NATIONAL LEASING, INC. ("Lessor") hereby leases to Lessee and Lessee leases from
Lessor, in accordance with the terms and conditions hereinafter set forth, the
equipment and property purchased by Lessor for lease to the Lessee hereunder
together with all replacement parts, additions, accessories, alterations and
repairs incorporated therein or now hereafter affixed thereto Add-on Items (as
defined herein) (herein collectively referred to as the "Equipment") described
in each Schedule which may be executed by Lessor and Lessee from time to time
(individually a "Schedule" and collectively, the "Schedules"), each of which is
made a part hereof. For all purposes of this Master Lease Agreement ("Lease"),
each Schedule relating to one or more items of Equipment shall be deemed a
separate lease incorporating all of the terms and provisions of this Lease. In
the event of a conflict between the terms of this Lease and the terms and
conditions of any Schedule, the terms and conditions of the Schedule shall
govern and control that Schedule.

1. TERM AND RENTAL. The term of this Lease (the "Initial Lease Term") for any
item Equipment shall be set forth in the Schedule relating to such item of
Equipment and shall commence (the "Commencement Date") on the Acceptance Date.
The "Acceptance Date" with respect to each Schedule shall be the applicable of
either: (1) the date of delivery to Lessee of all of the Equipment to be leased
thereunder; (2) in the case of Equipment which is the subject of a sale and
leaseback between Lessor and Lessee, the date upon which Lessor purchases such
Equipment from Lessee; or (3) in the case of Equipment requiring installation,
the date of installation of the Equipment. If the Acceptance Date is other than
the first day of a calendar quarter, then the Commencement Date of the Initial
Lease Term set forth in any Schedule shall be the first day of the calendar
quarter following the month which includes the Acceptance Date and Lessee shall
pay to Lessor, in addition to all other sums due hereunder, an amount equal to
one-thirtieth of the amount of the average monthly rental payment due or to
become due hereunder multiplied by the number of days from and including the
Acceptance Date to the Commencement Date of the Initial Lease Term set forth in
the Schedule. During the entire Initial Lease Term and any extension or renewal
of the term of this Lease, Lessee agrees to pay the total rental due hereunder
which shall be the total amount of all rental payments set forth in the Schedule
plus such additional amounts as may become due hereunder or pursuant to any
written modification hereof or additional written agreement hereto. Except as
otherwise specified in the Schedule, rental payments payable hereunder shall be
due monthly and shall be payable in advance on the first day of each month
during the term of this Lease beginning with the Commencement Date of the
Initial Lease Term. All rental payments due hereunder shall be sent to the
address of the Lessor specified in this Lease or in the Schedule or as otherwise
directed by the Lessor in writing. Rental payments or any other payments due
hereunder not made by their schedule due date shall be overdue and shall be
subject to a service charge in an amount equal to two percent (2%) per month or
the maximum rate permitted by law whichever is less (the "Service Charge Rate")
applied to amount of the overdue payments from the date due until paid. If
Lessor shall at any time accept a rental payment after it shall become due, such
acceptance shall not constitute or be construed as a waver of any or all of
Lessor's rights hereunder, including without limitation those rights of Lessor
set forth in Sections 12 and 13 hereof.

2. TITLE. This is an agreement of lease only. Except as otherwise provided in
any applicable Schedule, Lessee shall have no right, title or interest in or to
the Equipment leased hereunder, except as to the lawful use thereof subject to
the terms and conditions of this Lease. All of the Equipment shall remain
personal property (whether or not the Equipment may at any time become attached
or affixed to real property). The Equipment is and shall remain the sole and
exclusive property of Lessor or its assignees. All replacement parts,
modifications, repairs, alterations, additions and accessories now or hereafter
incorporated in or affixed to the Equipment whether before or after the
Commencement Date (herein collectively called "Add-on Items") are hereby
included in the definition of "Equipment." All Add-on Items shall become the
property of Lessor upon being so incorporated or affixed to the Equipment and
shall be returned to Lessor as provided in Section 3 (other than alterations,
additions and accessions that are attached or affixed by Lessee with notice to
Lessor after the Commencement Date for which the Lessor has not given value or
purchased and which are readily removable by Lessee from the Equipment without
any value or functionality to the Equipment). Upon the request of Lessor, Lessee
will affix to the Equipment labels or other markings supplied by Lessor
indicating its ownership of the Equipment and shall keep the same affixed for
the entire term of this Lease. Lessee agrees to promptly execute and deliver or
cause to be executed and delivered to Lessor and Lessor is hereby authorized to
record or file, any statement and/or instrument reasonably requested by Lessor
for the purpose of showing Lessor's interest in the Equipment, including without
limitation, financing statements, security agreements and waivers with respect
to rights in the Equipment form any owners of mortgagees of any real estate
where the Equipment may be located. In the event that Lessee fails or refuses to
execute and/or file Uniform Commercial Code financing statements or other
instruments or recordings which Lessor or its assignee reasonably deems
necessary to perfect or maintain perfection of Lessor's or its assignee's
interests hereunder, Lessee hereby appoints Lessor as Lessee's limited
attorney-in-fact to execute and record all documents necessary to perfect or
maintain the

                                       1
<PAGE>   2
perfection of Lessor's interests hereunder. Lessee shall pay Lessor for any
costs or fees relating to any filings hereunder including, but not limited to
actual out of pocket costs, fees, searches, documentation preparation,
documentary stamps, privilege taxes and reasonably attorneys' fees. If any item
of Equipment includes computer software purchased by Lessor for which Lessor has
given Lessee value, Lessee shall upon request made by Lessor, execute and
deliver and shall cause Seller (as hereinafter defined) to deliver all such
documents as are necessary to effectuate assignment of all software licenses to
Lessor.

3. ACCEPTANCE AND RETURN OF EQUIPMENT. Lessor shall, at any time prior to
unconditional acceptance of all Equipment by Lessee, have the right to cancel
this Lease with respect to such Equipment (and if the Equipment or any portion
thereof has not previously been delivered, Lessor may refuse to pay for the
Equipment or any portion thereof or refuse to cause the same to be delivered)
if: (a) the Acceptance Date with respect to any item of Equipment to be leased
pursuant to any Schedule has not occurred within ninety (90) days of the
estimated Acceptance Date set forth in such Schedule or (b) there shall be, in
the reasonable judgement of Lessor, a material adverse change in the financial
condition or credit standing of Lessee or of any guarantor of Lessee's
performance under this Lease since the date of the most recent financial
statements of Lessee or of such guarantor submitted to Lessor. Upon any
cancellation by Lessor pursuant to this Section or the provisions of any
Schedule, Lessee shall forthwith reimburse to Lessor all sums paid by Lessor
with respect to such Equipment plus all costs and expenses of Lessor incurred in
connection with such Equipment and any interest or rentals due hereunder in
connection with such Equipment and shall pay to Lessor all other sums then due
hereunder, whereupon if Lessee is not then in default and has fully performed
all of its obligations hereunder, Lessor will, upon request of Lessee, transfer
to Lessee without warranty or recourse any rights that Lessor may then have with
respect to such Equipment.

Lessee agrees to promptly execute and deliver to Lessor (in no event later than
15 days after the Acceptance Date) a confirmation by Lessee of unconditional
acceptance of the Equipment in the form supplied by Lessor (the "Equipment
Acceptance"). Lessee agrees, before execution of the aforesaid Equipment
Acceptance, to inform Lessor in writing of any defects in the Equipment, or in
the installation thereof, which have come to the attention of Lessee or its
agents and which might give rise to a claim by Lessee against the Seller or any
other person. If Lessee fails to give notice to Lessor of any such defects or
fails to deliver to Lessor the Equipment Acceptance as provided herein, it shall
be deemed an acknowledgement by Lessee (for purposes of this Lease only) that no
such defects in the Equipment or its installation exist and it shall be
conclusively presumed, solely as between Lessor and its assignees and Lessee,
that such Equipment has been unconditionally accepted by Lessee for lease
hereunder.

Except as otherwise provided in any Schedule, upon expiration or the
cancellation or termination of the Lease with respect to any Equipment, Lessee
shall return the Equipment to Lessor as provided herein. Lessee shall provide
Lessor with not less than ninety (90) days prior written notice of its intention
to return the Equipment upon expiration of the Initial Lease Term. Upon
expiration or the cancellation or termination of the Lease with respect to any
Equipment, Lessee shall, at its own expense, assemble, crate, insure and deliver
all of the Equipment and all of the service records and all software and
software documentation subject to this Lease and any Schedules hereto to Lessor
in the same good condition and repair as when received, reasonable wear and tear
resulting only from proper use thereof excepted, to such reasonable destination
within the continental United States as Lessor shall designate with all packing,
drayage and freight charges to the return destination designated by Lessor
prepaid by Lessee with evidence of transit insurance on all items of Equipment
at no less than their estimated fair market value as specified by Lessor. Lessee
shall, immediately prior to such return of each item of Equipment or commercial
unit of Equipment, provide to Lessor a letter from the manufacturer of the
equipment or another service organization reasonably acceptable to Lessor
certifying that said items is in good working order, with reasonable wear and
tear resulting from proper use thereof excepted, whether such item is eligible
for a maintenance agreement by such manufacturer, and all software and related
attachments are included thereon. If any computer software requires relicensing
when removed from Lessee's premises, Lessee shall bear all costs of such
relicensing. Except as otherwise expressly provided in the Schedule, if Lessee
fails for any reason to provide the notice set forth above or Lessee fails to
redeliver the Equipment back to Lessor accordance with the terms set forth
above, Lessee shall pay to Lessor, at Lessor's election, an amount equal to the
highest monthly payment set forth in the Schedule for a period of not less than
three (3) months and at the end of such period of time ("Holdover Period").
Except as otherwise expressly provided in the Schedule, if Lessee fails or
refuses to return the Equipment as provided herein at the end of any Holdover
Period, Lessee shall pay to Lessor, at Lessor's option, an amount equal to the
highest monthly rental payment set forth in the Schedule for each month or
portion thereof, until Lessee so returns the Equipment to Lessor. Should Lessor
permit use by Lessee of any Equipment beyond the Initial Lease Term, or, if
applicable, any exercised extension or renewal term, the lease obligations of
Lessee shall continue and such permissive use shall not be construed as a
renewal of the term thereof, or as a waver of any right or continuation of any
obligation of Lessor hereunder, and Lessor may take possession of any such
Equipment at any time upon demand.

4. DISCLAIMER OF WARRANTIES. LESSEE HAS EXCLUSIVELY SELECTED AND CHOSEN THE
TYPE, DESIGN, CONFIGURATION, SPECIFICATION AND QUALITY OF THE EQUIPMENT HEREIN
LEASED AND THE VENDOR, DEALER, SELLER, MANUFACTURER OR SUPPLIER THEREOF (HEREIN
COLLECTIVELY CALLED "SELLER"), AS SET FORTH IN THE SCHEDULES, LESSOR MAKES NO
REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, AS TO ANY MATTER
WHATSOEVER, INCLUDING WITHOUT LIMITATION, THE CONDITION OF THE

                                       2
<PAGE>   3
EQUIPMENT, ITS MERCHANTABILITY OR ITS FITNESS, ADAPTABILITY, ANY IMPLIED
WARRANTY OR QUIET ENJOYMENT OR NON-INTERFERENCE OR SUITABILITY FOR ANY
PARTICULAR PURPOSE, AND, LESSEE LEASES, HIRES AND RENTS THE EQUIPMENT "AS IS,
WHERE IS." Lessee understands and agrees that neither Seller, nor any agent of
Seller, is an agent of Lessor or is in any manner authorized to waive or alter
any term or condition of this Lease. Lessor shall not be liable for any loss or
damage suffered by Lessee or by any other person or entity, direct or indirect
or consequential, including, but not limited to, business interruption and
injury to persons or property, resulting from non-delivery or late delivery,
installation, failure or faulty operation, condition, suitability or use of the
Equipment leased by Lessee hereunder, or for any failure of any representations,
warranties or covenants made by the Seller. Any claims of Lessee, with respect
to claims discussed in the preceding sentences, shall be made against Lessor but
shall be made, if at all, solely and exclusively against Seller, or any persons
other than the lessor. Lessor hereby authorizes Lessee to enforce during the
term of this Lease, in its name, but at Lessee's sole effort and expense, all
warranties, agreements or representations, if any, which may have been made by
Seller to Lessor or to Lessee, and Lessor hereby assigns to Lessee solely for
the limited purpose of making and prosecuting any such claim, all rights which
Lessor may have against Seller for breach of warranty or other representation
respecting the Equipment.

5. CARE, TRANSFER AND USE OF EQUIPMENT. Lessee, at its own expense, shall
maintain the Equipment in good operating condition, repair and appearance in
accordance with all Seller's specifications and in compliance with all laws and
regulations applicable to the Equipment, Lessee and its business and shall
protect the Equipment from deterioration except for reasonable wear and tear
resulting only from proper use thereof. When generally offered with respect to
the Equipment, Lessee shall, at its expense, keep a maintenance contract in full
force and effect, throughout the term of this Lease and any Schedule hereto
unless otherwise agreed on the Schedule. The disrepair or inoperability of the
Equipment regardless of the cause thereof shall not relieve Lessee of the
obligation to pay rental hereunder. Lessee shall not make any modification,
alteration or addition to the Equipment (other than normal operating accessories
or controls). Lessee will not, and will not permit anyone other than the
authorized field engineering representatives of Seller or other maintenance
organization reasonably acceptable to Lessor to effect any inspection,
adjustment, preventative or remedial maintenance or repair to the Equipment.
LESSEE MAY NOT (A) RELOCATE OR OPERATE THE EQUIPMENT AT LOCATIONS OTHER THAN THE
PREMISES OF LESSEE SPECIFIED IN THE APPLICABLE SCHEDULE (THE "PREMISES"), EXCEPT
WITH LESSOR'S PRIOR WRITTEN CONSENT, WHICH SHALL NOT BE UNREASONABLY WITHHELD IF
SUCH OTHER LOCATION WITHIN THE CONTINENTAL UNITED STATES, OR (B) SELL, CONVEY,
TRANSFER, ENCUMBER, PART WITH POSSESSION OF, OR ASSIGN ANY ITEM OF EQUIPMENT OR
ANY OF ITS RIGHTS HEREUNDER, AND ANY SUCH PURPORTED TRANSACTION SHALL BE NULL
AND VOID AND OF NO FORCE OR EFFECT. In the event of a relocation of the
Equipment or any item thereof to which Lessor consents, all costs (including any
additional property taxes or other taxes and any additional expense of insurance
coverage) resulting from any such relocation, shall be promptly pad by Lessee
upon presentation to Lessee of evidence supporting such cost. Lessor shall have
the right during normal hour upon reasonable notice to Lessee, subject to
applicable laws and regulations, to enter Lessee's Premises in order to inspect,
observe, affix labels or other markings, or to exhibit the Equipment to
prospective purchasers or future lessees thereof, or to otherwise protect
Lessor's interest therein.

6. NET LEASE. THIS LEASE AND ANY SCHEDULE HERETO IS A NET LEASE, AND ALL
PAYMENTS HEREUNDER ARE NET TO LESSOR. All taxes, assessments, licenses, and
other charges (including, without limitation personal property taxes and sales
taxes, use taxes, leasing taxes and all other taxes based on gross receipts) and
penalties and interest on such taxes imposed, levied or assessed on the
ownership, possession, rental or use of the Equipment after delivery of the
Equipment to Lessee and thereafter dung the term of this Lease and any Schedule
hereto (except for Lessor's federal or state net income taxes) shall be paid by
Lessee when due and before the same shall become delinquent, whether such taxes
are assessed or would ordinarily be assessed against Lessor or Lessee. To the
extent possible under applicable law, for persons property or ad valorem tax
return purposes only. Lessee shall include the Equipment on such reports and
returns as may be required by local law, which returns shall be timely filed by
it. Lessee shall provide Lessor with evidence that Lessee has complied with the
foregoing provisions. In any event, Lessee shall file all tax returns required
for itself or Lessor with respect to the Equipment and this Lease and Lessor
hereby appoints Lessee as its attorney-in-fact for such purpose. In case of
failure by Lessee to so pay said taxes, assessments, licenses or other charges,
Lessor may pay all or any part of such items, in which event the amount so paid
by Lessor including any interest or penalties thereon and reasonable attorneys'
fees incurred by Lessor in pursuing its fights against Lessee or defending
against any claims or defenses asserted by or through Lessee shall be
immediately paid by Lessee to Lessor as additional rental hereunder. Lessee
shall promptly pay all costs, expenses and obligations of every kind and nature
incurred in connection with the use or operation of the Equipment which may
arise or become due during the term of this Lease and any Schedule hereto,
whether or not specifically mentioned herein. In case of failure by Lessee to
comply with any provision of this Lease and any Schedule hereto, Lessor shall
have the right, but not the obligation, to effect such compliance on behalf of
Lessee. In such event, all costs and expenses incurred by Lessor in effecting
such compliance shall be immediately payable by Lessee to Lessor as additional
rental hereunder.

7. INDEMNITY. Lessee shall at its expense: (i) indemnify, protect and defend
Lessor's title to the Equipment from and against all persons claiming against or
through Lessee; (ii) at all times keep the Equipment then subject to this Lease
free from any and all liens, encumbrances, attachments, levies,

                                       3
<PAGE>   4
executions, burdens, charges or legal process of any and every type whatsoever;
(iii) give Lessor immediate written notice of any breach of this Lease described
in clause (ii); and (iv) indemnify, protect and save Lessor harmless from any
loss, cost or expense (including reasonable attorneys' fees) caused by the
Lessee's breach of any of the provisions of this Lease, whether incurred by
Lessor in pursuing its rights against Lessee or defending against any claims or
defenses asserted by or through Lessee. Lessee shall and does hereby agree to
indemnify, defend and hold Lessor and its assigns harmless from and against any
and all liability, loss, costs, injury, damage, penalties, suits, judgements,
demands, claims, expenses and disbursements (including without limitation,
reasonable attorneys' fees incurred by Lessor in pursuing its rights against
Lessee or defending against any claims or defenses asserted by or through
Lessee) of any kind whatsoever arising out of, on account of, or in connection
with this Lease and the Equipment leased hereunder, including, without
limitation, its manufacture, selection, purchase, delivery, rejection,
installation, ownership, possession, leasing, renting, operation, control, use,
maintenance and the return thereof except for any such claims or damages from
Lessor's gross negligence or wilful misconduct. This indemnity shall survive the
Initial Lease Term or earlier cancellation or termination of this Lease and any
Schedule hereto.

8. INSURANCE. Commencing on the date that risk of loss or damage passes to
lessor from the Seller of any Equipment covered under this Lease and continuing
until Lessee has re-delivered possession of the Equipment to lessor, Lessee
shall, at its own expense, keep the Equipment (including all Add-on Items
thereto) insured against all risks of loss or damage from every and any cause
whatsoever in such amounts (but in no event less than the greater of the
replacement value thereof or the amount set forth in any applicable Casualty
Schedule, whichever is higher) with such deductibles and exclusions as approved
by Lessor and in such form as is reasonably satisfactory to Lessor. All such
insurance policies shall protect Lessor and Lessor's assignee(s) as loss payees
as their interests may appear. Lessee shall also, at its own expense, carry
public liability insurance, with Lessor and Lessor's assignee(s) as an
additional insured, in such amounts with such companies and in such forms as is
reasonably satisfactory to Lessor, with respect to injury to person or property
resulting from or based in way upon or in any way connected with or relating to
the installation, use or alleged use, or operation of any or all of the
Equipment, or its location or condition.

Not less than ten days prior to the Acceptance Date, Lessee shall deliver to
Lessor satisfactory evidence of such insurance and shall further deliver
evidence of renewal of each policy not less than thirty (30) days prior to
expiration thereof. If the Lessee fails to provide evidence of such insurance or
to deliver evidence of renewal of each such policy then Lessee agrees to pay
Lessor a non-compliance fee equal to 1% of the Equipment Cost for all Equipment
covered under this Lease each month until such evidence is provided to Lessor.
Each such policy shall contain an endorsement providing that the insurer will
give Lessor not less than thirty (30) days prior written notice of the effective
date of any alteration, change, cancellation, or modification of such policy or
the failure by Lessee to timely pay all required premiums, costs or charges with
respect thereto. Upon Lessor's request, Lessee shall cause its insurance
agent(s) to execute and deliver to Lessor Loss Payable Clause Endorsement and
Additional Insured Endorsement (bodily injury and property damage liability
insurance) forms provided to Lessee by Lessor. In case of the failure to procure
or maintain such insurance, Lessor shall have the right, but not the obligation,
to obtain such insurance and any premium paid by Lessor shall be immediately due
and payable by Lessee to Lessor as additional rent hereunder. The maintenance of
any policy or policies of insurance pursuant to this Section shall not limit any
obligation or liability of Lessee pursuant to Sections 7 or 9 or any other
provision of this Lease and any Schedule hereto.

9. RISK OF LOSS. Until such time as the Equipment is returned and delivered to
and accepted by Lessor at the expiration of this Lease, pursuant to the terms of
this Lease and any Schedule hereto, Lessee hereby assumes and shall bear the
entire risk of loss, damage, theft and destruction of the Equipment, or any
portion thereof, from any cause whatsoever ("Equipment Loss"). Without
limitation of the foregoing, no Equipment Loss shall relieve Lessee in any way
from its obligations hereunder. Lessee shall promptly notify Lessor in writing
of any Equipment Loss. In the event of any such Equipment Loss, Lessee shall:
(a) in the event Lessor determines such Equipment to be repairable, promptly
place, at Lessee's expense, the Equipment in good repair, condition and working
order in accordance with Seller's specifications and to the satisfaction of
Lessor, or (b) in the event an actual or constructive total loss of any item of
Equipment, at lessor's option: (i) promptly replace, at Lessee's expense, the
Equipment with like equipment of the same or a later model with the same Add-on
Items as the Equipment, and in good repair, condition and working order in
accordance with the Seller's specifications and to the satisfaction of Lessor;
or (ii) immediately pay to Lessor the sum of (a) any accrued and unpaid rental
or any amounts due hereunder plus (b) an amount equal to the present value of
the total amount of unpaid rentals and all other amounts due and to become due
under any applicable Schedule during the term thereof as of the date of any
payment, discounted at a rate equal to discount rate of the Federal Reserve Bank
of Chicago as of the Commencement Date of the Lease with respect to each
applicable Schedule shall be paid to Lessor by Lessee, plus (c) an additional
amount equal to the present value of the estimated fair market value of the
Equipment at the end of the Initial Lease Term applicable to such Equipment (the
"End of Term Value"). In no event shall the amount of such End of Term Value for
the Equipment be less than twenty percent (20%) of the actual cost of the
Equipment unless a lesser amount is actually specified as the purchase option
price, if any, in the applicable Schedule. If a Casualty Schedule has been made
a part of any applicable Schedule, then in lieu of the amounts specified in
subparagraphs (b)(ii)(b) and (c) Lessee shall pay Lessor the amounts obtained by
multiplying the actual Equipment Cost as specified in the applicable Schedule by
the percentage contained in any applicable Casualty Schedule for the date of
such Equipment Loss.

                                       4
<PAGE>   5
If no Casualty Schedule has been made a part of any applicable Schedule, an
amount equal to the present value of the total amount of unpaid rentals and all
other amounts due and to become due under any applicable Schedule during the
term thereof as of the date of any payment, discounted at a rate equal to
discount rate of the Federal Reserve Bank of Chicago as of the Commencement Date
of the Lease with respect to each applicable Schedule shall be paid to Lessor by
Lessee, plus an additional amount equal to the estimated fair market value of
die Equipment at the end of the initial Lease Term applicable to such Equipment
(the "End of Term Value"). In no event shall the amount of such End of Term
Value for the Equipment be less than twenty percent (20%) of the actual cost of
the Equipment unless a purchase option is granted (or other end of term payment
is required) under this Lease for other there the fair market value of the
Equipment then the actual amount of such Purchase Option Price (or other end of
term payment) specified in the applicable Equipment Schedule shall be due and
payable to Lessor as the End of Term Value undo the section or such lesser or
greater amount specified in the applicable Schedule.

In the event Lessee is required to repair or replace any such item of Equipment
pursuant to Subsections (a) or (b)(i) of the preceding sentence, the insurance
proceeds received 6t' Lessor, if any, pursuant to Section 8, after the use of
such funds to pay any unpaid amounts then due hereunder, shall be paid to Lessee
or, if applicable, to a third party repairing or replacing the Equipment upon
Lessee's furnishing proof reasonably satisfactory to Lessor that such repair or
replacement has been completed in a reasonably satisfactory manner. In the event
Lessor elects option (b)(ii), Lessee shall be entitled to a credit against the
payment required by said Subsection in an amount equal to such insurance
proceeds actually received by Lessor pursuant to Section 8 on account of such
Equipment, and, upon payment by Lessee to Lessor of all of the sums required
pursuant to Subsection (b)(ii), the applicable Schedule shall terminate with
respect to such item of Equipment and Lessee shall be entitled to whatever
interest Lessor may have in such item AS IS, WHERE IS AND WITH ALL FAULTS in its
then condition and location without warranties of any type whatsoever, express
or implied.

10. COVENANTS OF LESSEE. Lessee agrees that its obligations under this Lease and
any Schedule hereto, including without limitation, the obligation to pay rental,
are irrevocable and absolute, shall not abate for any reason whatsoever
(including any claims against Lessor), and shall continue in full force and
effect regardless of say inability of Lessee to use the Equipment or arty part
thereof for any reason whatsoever including, without limitation, war, act of
God, storms, governmental regulations, strike or other labor troubles, loss,
damage, destruction, disrepair, obsolescence, failure of or delay in delivery of
the Equipment or failure of the Equipment to properly operate for any cause. In
the event of any alleged claim (including a claim which would otherwise be in
the nature of a set-off) against Lessor, Lessee shall fully perform and pay its
obligations hereunder (including the payment of all tarts, without set-off or
defense of any kind) and its only exclusive recourse against Lessor shall be by
a separate action. Lessee agrees to furnish promptly to Lessor the annual
financial statements of Lessee (and of any guarantors of Lessee's performance
trader this Lease and any Schedule hereto), prepared in accordance with
generally accepted accounting principles and such interim financial statements
of Lessee as Lessor may reasonably require during the entire term of the Lease
and any Schedule hereto. Either independent certified public accountants or the
Lessee's chief financial officer as requested by Lessor shall certify all such
annual financial statements. Lessee, if requested by Lessor prior to the initial
purchase by Lessor of Equipment for lease hereunder, shall provide at Lessee's
expense an opinion of its counsel acceptable to Lessor affirming the covenants,
representations and warranties of Lessee under this Lease and any Schedule
hereto. So long as there are amounts due Lessor under this Lease, Lessee shall
supply Lessor with such other financial and operating performance data as is
provided to its outside investors or commercial lenders and, if applicable,

breach or failure and such remedy is in fact achieved within a time period
agreed to by Lessor); or (vi) shall become insolvent or bankrupt or make an
assignment of the benefit of creditors or consent to the appointment of a

Default (the "Default Date") set forth in Section 12, Lessor may, in its sole
and absolute discretion, do any one or more of the following: (a) upon notice to
Lessee cancel all or any portion of this Lease or any Schedules executed
pursuant thereto; (b) enter Lessee's Premises and without removal of the
Equipment, render the Equipment unusable or, require Lessee to assemble the

(ii) the present value of all future rentals and other amounts described in the
Lease and not included in the above discounted to the Default Date at a rate

the facts and circumstances at the time such Schedule commenced), (iii) all
commercially reasonable costs and expenses incurred by Lessor in enforcing
Lessor's rights under this Lease, or defending against any claims or defenses

available to it under the Uniform Commercial Code or any other applicable law.

If Lessor elects to dispose of any Equipment recovered from the possession of
Lessee after an Event of Default, Lessor shall dispose of such Equipment in a
commercially reasonable manner, Lessor reserves the right, in its sole and
absolute discretion, to control the timing and negotiate the terms of any
re-leasing or re-sale of any or all of the Equipment at a public

                                       6
<PAGE>   7
auction or in a private sale, at such time, on such terms and with such notice
as Lessor shall in its sole and absolute discretion deem commercially
reasonable. In such event, without any duty on Lessor's part to effect any such
re-lease or sale of the Equipment, Lessor will credit the present value of any
proceeds from such sale or re-lease actually received and retainable by it (net
of any and all costs or expenses) discounted from the date of Lessor's receipt
thereof to the Default Date at 2 1/2% in excess of the Prime Rate (or its
equivalent) per annum in effect at the First National Bank of Chicago on the
date of such payment to the amounts due to Lessor from Lessee under the
provisions of (c), (d) and/or (e) above. A cancellation of this Lease shall
occur only upon notice by Lessor and only as to such items of Equipment as
Lessor specifically elects to cancel and this Lease shall continue in full force
and effect as to the remaining items of Equipment, if any. If this Lease and/or
any Schedule is deemed at any time to be one intended as security, Lessee agrees
that the Equipment shall secure, in addition to the indebtedness set forth
herein, any other indebtedness at any time owing by Lessee to Lessor. No remedy
referred to in this Section is intended to be exclusive, but shall be cumulative
and in addition to any other remedy referred to above or otherwise available to
Lessor at law or in equity. No express or implied waiver by Lessor of any
default shall constitute a waiver of any other default by Lessee or a waiver of
any of Lessor's rights.

14. ASSIGNMENT BY LESSOR. LESSOR MAY, (WITH OR WITHOUT NOTICE TO LESSEE) SELL,
TRANSFER, ASSIGN OR GRANT A SECURITY INTEREST IN ALL OR ANY PART OF ITS INTEREST
IN THIS LEASE, ANY SCHEDULE, ANY ITEMS OF EQUIPMENT OR ANY AMOUNT PAYABLE
HEREUNDER. In such an event, Lessee shall, upon receipt of written notice,
acknowledge any such sale, transfer, assignment or grant of a security interest
and shall pay its obligations hereunder or amounts equal thereto to the
respective transferee, assignee or secured party in the manner specified in any
instructions received from Lessor. Notwithstanding any such sale, transfer,
assignment or grant of a security interest by Lessor and so long as no Event of
Default shall have occurred hereunder, neither Lessor nor any transferee,
assignee or secured party shall interfere with Lessee's right of use or quiet
enjoyment of the Equipment. In the event of such sale, transfer, assignment or
grant of a security interest in all or any part of this Lease and any Schedule
hereto, or in the Equipment or in sums payable hereunder, as aforesaid, Lessee
agrees to execute such documents as may be reasonably necessary to evidence,
secure and complete such sale, transfer, assignment or grant of a security
interest and to perfect the transferee's assignee's or secured party's interest
therein (with any filing fees at Lessor's expense) and Lessee further agrees
that the rights of any transferee, assignee or secured party shall not be
subject to any defense, set-off or counterclaim that Lessee may have against
Lessor or any other party, including the Seller, which defenses, set-offs and
counterclaims shall be asserted only against such party, and that any such
transferee, assignee or secured party shall have all or Lessor's rights
hereunder, but shall assume none of Lessor's obligations hereunder. Lessee
acknowledges that any assignment or transfer by Lessor shall not materially
change Lessee's duties or obligations under this Lease and shall not materially
increase the burdens and risks imposed upon Lessee.

15. MISCELLANEOUS. All notices and demands relating hereto shall be in writing
and sent by either any nationally recognized overnight air courier or by
certified mail, return receipt requested, to Lessor or Lessee at their
respective addresses above or shown in the Schedule, or at any other address
designated by notice served in accordance herewith. Notice by overnight air
courier shall be effective one (1) business day after delivery. Notice by
certified mail shall become effective five (5) business days after deposit in
the United States mail, with proper postage prepaid, to the party intended to be
served at the address designated herein. All obligations of Lessee shall survive
the termination or expiration of this Lease and any Schedule hereto. If more
than one Lessee is named in this Lease, the liability of each hereunder to
Lessor shall be joint and several. Any general partner executing this Lease on
behalf of the Lessee agrees that its liability to Lessor hereunder shall be
absolute, primary and direct, and that Lessor shall not be required to pursue
any right or remedy it may have against the Lessee under the Lease (and shall
not be required to first commence any action or obtain any judgment against
Lessee) before enforcing this liability against such general partner, and that
such general partner will, upon demand, pay Lessor the amount of all sums then
due under the Lease, the payment of which, by Lessee, is in default under the
Lease, and will, upon demand, perform all other obligations of Lessee, the
performance of which, by Lessee, is in default under the Lease. Lessee shall,
upon request of Lessor from time to time, perform all acts and execute and
deliver to Lessor all documents which Lessor deems reasonably necessary to
implement this Lease and any Schedule hereto, including, without limitation,
certificates addresses to such persons as Lessor may direct stating that this
Lease and the Schedule hereto is in full force and effect, that there are no
amendments or modifications thereto, that Lessor is not in default hereof or
breach hereunder, setting forth the date to which rentals due hereunder have
been paid, and stating such other matters as Lessor may reasonably request. This
Lease and any Schedule hereto shall be binding upon the parties and their
successors, legal representatives and assigns. Lessee's successor and assigns
shall include, without limitation, a receiver, debtor-in-possession, or trustee
of or for Lessee. If any person, firm, corporation or other entity shall
guarantee this Lease and the performance by Lessee of its obligations hereunder,
all of the terms and provisions hereof shall be duly applicable to such Obligor.

16. CONDITIONS PRECEDENT TO LEASING. (i) Lessor shall have no obligation to
purchase any Equipment for lease to Lessee under any Schedule hereunder unless
or until acceptable documentation, the form of which will be provided by Lessor
has been executed by Lessee and delivered to Lessor; (ii) Lessor has confirmed
with Lessee that no material adverse change in Lessee's financial condition and
business prospects has occurred prior to each purchase of Equipment.

17. INVALIDITY. In the event that any provision of this Lease and any Schedule
hereto shall be unenforceable in whole or in

                                       7
<PAGE>   8
party, such provision shall be limited to the extent necessary to render the
same valid, or shall be excised from this Lease or any Schedule hereto, as
circumstances may require, and this Lease and the applicable Schedule shall be
construed as if said provision had been incorporated herein as so limited, or as
if said provision had not been included herein, as the case may be without
invalidating any of the remaining provisions hereof.

18. END OF TERM OPTIONS. Provided that the Lease has not been terminated and
that no Event of Default or event which, with notice or lapse of time or both,
would become an Event of Default shall have occurred and shall be continuing,
Lessee shall at the end of the Initial Lease Term of the first Schedule be
entitled to elect and to exercise one of the options, if any, indicated in the
applicable Schedule which election shall be binding on Lessee with respect to
all Schedules entered into between Lessor and Lessee under this Lease. The
foregoing options granted hereunder shall be exercised by written notice
delivered to Lessor by Lessee not more than 180 days and not less than ninety
(90) days prior to the expiration of the Initial Lease Term of the Equipment,
subject to Schedule No. 001.

19. PROGRESS PAYMENTS. If requested by Lessee, progress payments will be made
for any amount over the Minimum Invoice Amount specified on each Progress
Payment Authorization per invoice to vendors in accordance with Lessor's
standard procedures. Unless otherwise agreed by Lessor the minimum progress
payment amount shall not be less than the Minimum Progress Payment Amount
specified on the Progress Payment Authorization. Interim rent, on progress
payments, shall be payable from the date progress payments are made by Lessor to
the Commencement Date of the corresponding Schedule. Interim rent shall be
calculated at the daily equivalent of the Monthly Lease Rate Factor. Lessee
shall deliver to Lessor a Progress Payment Authorization, not less than 30 days
prior to the due date thereof and in a form acceptable to Lessor, to make a
progress payment and, provided on such due date no Events of Default have
occurred and be continuing hereunder or under the Lease, Lessor shall make the
progress payment set forth to the manufacturer(s) or supplier(s) as set forth in
such authorization.

20. LAW. This Lease and any Schedule hereto shall be binding only when accepted
by Lessor and shall in all respects be governed and construed, and the rights
and the liabilities of the parties hereto determined, except for local filing
requirements, in accordance with the laws of the State of Illinois, the
principle place of business of LINC Capital, Inc., the intended assignee of this
lease. LESSEE WAIVES TRIAL BY JURY AND SUBMITS TO THE JURISDICTION OF THE
FEDERAL DISTRICT COURT OR ANY STATE COURT LOCATED WITHIN COOK COUNTY IN THE
STATE OF ILLINOIS AND WAIVES ANY RIGHT TO ASSERT THAT ANY ACTION INSTITUTED BY
LESSOR IN ANY SUCH COURT IS IN THE IMPROPER VENUE OR SHOULD BE TRANSFERRED TO A
MORE CONVENIENT FORUM.

                            COMPAQ FINANCIAL SERVICES

                      MASTER LEASE AND FINANCING AGREEMENT

This Master Lease and Financing Agreement (together with Exhibits A through E
attached hereto and hereby made a part hereof, this "Master Agreement"), dated
as of November 1, 1999, is entered into by and between Compaq Financial Services
Corporation, a Delaware corporation ("Lessor"), and AppliedTheory Corporation, a
Delaware ("Lessee"). Capitalized terms used in this Master Agreement without
definition have the meanings ascribed to them in Section 31.

1. PURPOSE OF MASTER AGREEMENT. The purpose of this Master Agreement is to set
forth the general terms and conditions upon which (a) Lessor shall lease to
Lessee and Lessee shall lease from Lessor items of Hardware, Software or both
(such Hardware and Software being collectively referred to as "Equipment", and
each such lease of Equipment being referred to as a "Lease"), and (b) Lessor
shall provide financing to Lessee (each such financing transaction being
referred to as a "Financing") for software program license fees, maintenance
fees, fees for other services and other one-time charges ("Financed Items")
Lessee desires to finance hereunder. In connection with its execution of this
Master Agreement, Lessee shall deliver to Lessor an Officer's Certificate in
form and substance acceptable to Lessor, executed by a duly authorized officer
of Lessee and certifying as to, among other things, Lessee's authority to enter
into this Master Agreement and Leases and Financings hereunder and the authority
of Lessee's officers or representatives specified therein to execute this Master
Agreement and all other Fundamental Agreements.

2. ALTERNATIVE COMMENCEMENT PROCEDURES. Subject to the other terms and
conditions contained in this Master Agreement and the applicable Schedule or
Advance Pricing Agreement, Lessee may, at its option, enter into individual
Leases and Financings with Lessor under either or both of the following
procedures:

      A. TRADITIONAL PROCEDURE. (a) Execution of Schedule. Lessor and Lessee
mutually agree to enter into a Lease, a Financing or both by executing a
Schedule in the form of Exhibit A with such changes as Lessor and Lessee shall
have agreed to as conclusively evidenced by their execution thereof. Each such
Schedule shall specifically identify (by serial number or other identifying
characteristics) the items of Equipment to be leased under such Schedule (other
than items of System Software, which shall be deemed to be items of Software
leased under the Schedule pursuant to which the related items of Hardware are
leased), and the Financed Items to be financed under such Schedule. Each
Schedule, when executed by both Lessee and Lessor, together with this Master
Agreement, shall constitute a separate and distinct Lease, a separate and
distinct Financing, or a separate and distinct Lease and a separate and distinct
Financing, as the case may be, enforceable according to its terms. In the event
of any conflict between the terms of this Master Agreement and such Schedule,
the provisions of the Schedule shall govern.

      (b) Acceptance; Initial Term of Leases and Term of Financings. Lessee
shall accept the Equipment subject to a Lease and the Financed Items subject to
a Financing in accordance with Section 3. The Initial Term of each Lease and, if
applicable, the Term of any related Financing evidenced by a Schedule executed
pursuant to this Section 2.A shall begin on the Acceptance Date of the Equipment
subject to such Lease and shall continue for the period described in the
applicable Schedule. The Term of each Financing evidenced by a Schedule executed
pursuant to this Section 2.A that is unrelated to any Lease shall begin on the
Acceptance Date for the related Financed Items and shall continue for the period
described in the applicable Schedule.

      (c) Adjustments to Schedule. Lessee acknowledges that the Total Cost of
Equipment and Financed Items and the related Rent payments set forth in any
Schedule executed pursuant to this Section 2.A may be estimates, and if the
final invoice from the Seller specifies a Total Cost that is more or less than
the estimated Total Cost set forth in the Schedule, Lessee hereby authorizes
Lessor to adjust the applicable Total Cost and Rent payment on the Schedule to
reflect the final invoice amount (the "Final Invoice Amount"). However, if the
Final Invoice Amount exceeds the estimated Total Cost by more than 5%, Lessor
will notify Lessee and obtain Lessee's prior written approval of the
aforementioned adjustments. If Lessee fails to so approve any such adjustments
within 15 days of Lessor's request, then the affected Schedule shall terminate
without penalty to either Lessor or Lessee and Lessee shall be solely
responsible for all obligations arising under the applicable Purchase Documents,
including, without limitation, the obligation to purchase equipment and pay
Financed Items. All references in this Master Agreement and any Schedule to
Total Cost and Rent shall mean the amounts thereof specified in the applicable
Schedule, as adjusted pursuant to this paragraph. Lessee also acknowledges that
the Equipment and Financed Items described in a Schedule may differ from the
description of the Equipment and Financed Items set forth in the related
Acceptance Certificate and actually accepted by Lessee. Lessee hereby authorizes
Lessor to conform the description of the Equipment and Financed Items set forth
in any Schedule to the description thereof in the related Acceptance
Certificate. All references in the Master Agreement and any Schedule to the
Equipment subject to a Lease and the Financed Items subject to a Financing shall
mean the Equipment and Financed Items described in the applicable Schedule, as
conformed to the related Acceptance Certificate pursuant to this paragraph.

      B. FUNDING CONSOLIDATION PROCEDURE. (a) Execution of Advance Pricing
Agreement. Lessor and Lessee mutually agree to enter into one or more Leases,
Financings or both by executing, from time to time, an Advance Pricing Agreement
in the form of Exhibit B with such changes as Lessor and Lessee shall have
agreed to as conclusively evidenced by their execution thereof. Subject to the
following provisions of this Section 2.B, such Advance Pricing Agreement shall
constitute a commitment on the part of Lessor, during the Commitment Period
specified therein (i) to purchase Equipment of the type(s) described therein and
enter into one or more Leases of the same with Lessee at the lease rates set
forth therein, and (ii) to fund Financed Items of the type(s) described therein
and enter into one or more Financings of the same with Lessee at the financing
rates set forth therein; provided, however, that Lessor shall under no
circumstances be obligated to purchase Equipment or fund Financed Items if (x)
such purchase or funding would require Lessor to expend moneys in excess of the
Amount Available specified in the Advance Pricing Agreement less the aggregate
amount previously paid or committed to be paid by Lessor to acquire Equipment or
fund Financed Items during such Commitment Period, or (y) any Lessee Default
shall have occurred and be continuing under any Lease or Financing or any event
shall have occurred and be continuing which, with the giving of notice or the
passage of time or both, would constitute a Lessee Default under any Lease or
Financing, or (z) Lessee shall have failed to deliver to Lessor any financial
statements in accordance with the provisions of paragraph (f) below or any
material adverse change shall have occurred in Lessee's financial or operating
condition, as determined by Lessor in its sole discretion, after the date of the
last financial statements of Lessee delivered to Lessor prior to the execution
and delivery of such Advance Pricing Agreement.

      (b) Lessor's Purchase of Equipment and Funding of Financed Items. Subject
to the provisions of this Section 2.B and the applicable Advance Pricing
Agreement, Lessor shall, at Lessee's request made during the Commitment Period
specified in such Advance Pricing Agreement (i) purchase Equipment of the
type(s) described therein and enter into a Lease of such Equipment with Lessee,
and (ii) fund Financed Items of the type(s) described therein and enter into a
Financing with Lessee relating to such Financed Items. Until such time as Lessee
shall have executed and delivered to Lessor a Consolidating Schedule in
accordance with paragraph (d) below, each such Lease or Financing shall be
governed by the terms of this Master Agreement, the applicable Advance Pricing
Agreement and the Acceptance Certificate executed and delivered to Lessor by
Lessee pursuant to paragraph (c) below. Each such Acceptance Certificate shall
specifically identify (by serial number or other identifying characteristics)
the items of Equipment to be leased thereunder (other than items of System
Software, which shall be deemed to be items of Software leased together with the
related items of Hardware) and the Financed Items to be financed thereunder.
Until Lessee shall have executed and delivered to Lessor a Consolidating
Schedule, each such Acceptance Certificate, when executed and delivered by
Lessee and accepted by Lessor, together with this Master Agreement and the
applicable Advance Pricing Agreement, shall constitute a separate and distinct
Lease, a separate and distinct Financing, or a separate and distinct Lease and a
separate and distinct Financing, as the case may be, enforceable according to
its terms. In the event of any conflict among the terms of such documents, the
provisions of such Acceptance Certificate shall control over conflicting
provisions in such Advance Pricing Agreement or this Master Agreement and the
provisions of such Advance Pricing Agreement shall control over conflicting
provisions in this Master Agreement.

      (c) Acceptance; Initial Term of Leases and Term of Financing.
<PAGE>   2
Lessee shall accept the Equipment subject to a Lease and the Financed Items
subject to a Financing in accordance with Section 3. The Initial Term of each
Lease and, if applicable, the Term of any related Financing evidenced by an
Advance Pricing Agreement and an Acceptance Certificate shall begin on the
Acceptance Date of the Equipment subject to such Lease and shall continue for
the period determined pursuant to such Advance Pricing Agreement. The Term of
each Financing evidenced by an Advance Pricing Agreement and an Acceptance
Certificate that is unrelated to any Lease shall begin on the Acceptance Date
for the related Financed Items and shall continue for the period determined
pursuant to such Advance Pricing Agreement.

      (d) Periodic Consolidation of Leases and Financings. All Leases and
Financings commenced during a Consolidation Period (as specified in the
applicable Advance Pricing Agreement) pursuant to this Section 2.B shall be
consolidated into a single Schedule (a "Consolidating Schedule") in the form of
Exhibit C with such changes as Lessor and Lessee shall have agreed to as
conclusively evidenced by their execution thereof. Lessor shall prepare and
deliver to Lessee a Consolidating Schedule as of the close of each applicable
Consolidation Period. Lessee agrees to execute and deliver each Consolidating
Schedule to Lessor within 10 days after its receipt thereof from Lessor. From
and after Lessee's execution and delivery to Lessor of a Consolidating Schedule,
the Consolidating Schedule shall supersede the applicable Acceptance
Certificates and the Advance Pricing Agreement with respect to all Leases and
Financings commenced during the Consolidation Period to which such Consolidating
Schedule relates, and all such Leases shall be deemed to be a single, separate
and distinct Lease and all such Financings shall be deemed to be a single,
separate and distinct Financing, in each case governed by such Consolidating
Schedule and this Master Agreement and enforceable in accordance with its terms.
In the event of any conflict between the terms of this Master Agreement and such
Consolidating Schedule, the provisions of the Consolidating Schedule shall
govern.

      (e) Failure of Lessee to Deliver Consolidating Schedule. If Lessee fails
to execute and deliver to Lessor any Consolidating Schedule within 10 days after
its receipt thereof, Lessor may exercise its rights and remedies under Section
21 and 22 of this Master Agreement arising as a result of such failure, either
immediately or at any time during the Initial Term of the Leases or the Term of
the Financings to which such Consolidating Schedule relates. No delay in
exercising such rights or remedies shall operate as a waiver thereof. Lessee
acknowledges and agrees that Rent with respect to such Leases and Financings
shall be payable in the amounts and at the times determined pursuant to the
applicable Advance Pricing Agreement and Acceptance Certificates, regardless of
whether Lessee shall have received such Consolidating Schedule from Lessor or
executed and delivered the same to Lessor as of the time any such payment is
due.

      (f) Financial Statements. Lessee shall, at all times during which any
Advance Pricing Agreement is effective, deliver to Lessor its quarterly and
annual financial statements no later then 45 days after the end of each of
Lessee's fiscal quarters or 90 days after the end of each of Lessee's fiscal
years, as applicable. Such annual financial statements shall be audited and
certified by Lessee's independent certified public accountants.

3. ACCEPTANCE OF EQUIPMENT AND FINANCED ITEMS. (a) General. Lessee shall
unconditionally and irrevocably accept all Equipment under a Lease and, if
applicable, all related Financed Items subject to a Financing as soon as such
Equipment is delivered and inspected by Lessee or, if acceptance requirements
for such Equipment, related Financed Items or both are specified in the
applicable Purchase Documents, as soon as such requirements are met. Lessee
shall evidence such acceptance by executing and delivering to Lessor a properly
completed Acceptance Certificate in substantially the form of (i) Exhibit D if
the Lease or the Lease and the related Financing, as the case may be, is
evidenced by a Schedule executed pursuant to Section 2.A, or (ii) Exhibit E if
the Lease or the Lease and the related Financing, as the case may be, is being
commenced pursuant to an Advance Pricing Agreement executed pursuant to Section
2.B. Lessee agrees (y) to inspect all Equipment as soon as reasonably
practicable after the delivery thereof to Lessee or, if acceptance requirements
for such Equipment or any related Financed Items are specified in the applicable
Purchase Documents, as soon as reasonably practicable after being advised by the
Supplier that such requirements have been met, and (z) to complete, execute and
deliver to Lessor such Acceptance Certificate as soon as reasonably practicable
after its satisfactory completion of such inspection. In the case of a Financing
of Financed Items unrelated to any Equipment subject to a Lease, Lessee shall
unconditionally and irrevocably accept such Financed Items as soon as it shall
have become liable to pay for such Financed Items, and shall complete, execute
and deliver to Lessor an Acceptance Certificate in substantially the form of
Exhibit D or Exhibit E (as applicable) as soon as reasonably practicable
thereafter.

      (b) E-mail Acceptance. For its convenience and at its option, Lessee may
accept Equipment and Financed Items by electronic mail in accordance with this
paragraph, in lieu of the execution and physical delivery of Acceptance
Certificates provided for in paragraph (a) above. Subject to the terms and
conditions set forth below, a Valid E-mail Acceptance Certificate shall
constitute an original and authentic written Acceptance Certificate, duly
executed and delivered by an authorized representative of Lessee. A "Valid
E-mail Acceptance Certificate" means an electronic facsimile of an Acceptance
Certificate in substantially the form of Exhibit D or Exhibit E (as applicable)
properly completed and sent by an Authorized Lessee Representative from his or
her Authorized Lessee E-mail Address to an Authorized Lessor E-mail Address by
an electronic mail message confirming Lessee's acceptance of the Equipment or
Financed Items described therein. Upon request, Lessor shall provide to Lessee
electronic file copies of Exhibits D and E for Lessee's use under this
paragraph. The Authorized Lessee Representatives and their corresponding
Authorized Lessee E-mail Addresses and the Lessee Acceptance Confirmation Fax
Number are as specified in Section 29 or as designated by Lessee in a written
notice executed by a duly authorized officer of Lessee and delivered to Lessor
in accordance with Section 29. The Authorized Lessor E-mail Address(es) are
specified in Section 29. Lessee may unilaterally modify any of the Authorized
Lessee Representatives and Authorized Lessee E-mail Addresses and the Lessee
Acceptance Confirmation Fax Number by written notice of the modification
executed by a duly authorized officer of Lessee and delivered to Lessor in
accordance with Section 29. Lessor may unilaterally modify any Authorized Lessor
E-mail Address by written notice of the modification executed by a duly
authorized officer of Lessor and delivered to Lessee in accordance with Section
29. Upon Lessor's receipt of a Valid E-mail Acceptance Certificate from Lessee,
Lessor shall transmit to Lessee by confirmed facsimile transmission to the
Lessee Acceptance Confirmation Fax Number, a notice acknowledging Lessor's
receipt of the Valid E-mail Acceptance Certificate from Lessee. A Valid E-mail
Acceptance Certificate shall become effective and constitute Lessee's
unconditional and irrevocable acceptance of the Equipment or Financed Items
described therein, as of the Acceptance Date specified therein, at the end of
the second business day following the day on which Lessor shall have transmitted
such notice unless Lessee shall have delivered a written notice to Lessor in
accordance with Section 29 revoking such Valid E-mail Acceptance Certificate
prior to the end of such second business day. Lessor's transmission of such
notice shall constitute Lessor's acknowledgement and acceptance of the Valid
E-mail Acceptance Certificate. Lessee expressly waives any claim or defense that
any Valid E-mail Acceptance Certificate which was sent and became effective in
accordance with the above procedures does not constitute an original and
authentic written Acceptance Certificate, duly executed and delivered by Lessee.

4. LESSEE'S END-OF-LEASE-TERM OPTIONS; AUTOMATIC EXTENSION. Lessee shall have
the following options in respect of each Lease at the end of each of the Initial
Term, any Renewal Term and any optional extension of the Initial Term or any
Renewal Term:

      A. PURCHASE OPTION. Lessee may elect, by delivering to Lessor an
End-of-Term Notice at least 90 days prior to the expiration of the Initial Term,
any Renewal Term or any optional extension of the Initial Term or any Renewal
Term, to purchase any or all Units of Equipment then subject to such Lease
(other than items of Software that may not be sold by Lessor under the terms of
any applicable License Agreement) for an amount equal to the Fair Market Value
of such Units of Equipment as of the end of the Then Applicable Term, provided
no Lessee Default shall have occurred and be continuing. In the event of such an
election, Lessee shall pay such amount to Lessor, in immediately available
funds, on or before the last day of the Then Applicable Term. If Lessee shall
have so elected to purchase any of the Units of Equipment, shall have so paid
the applicable purchase price and shall have fulfilled the terms and conditions
of this Master Agreement, then on the last day of the Then Applicable Term (i)
the Lease with respect to such Units of Equipment shall terminate and, except as
provided in Section 27, Lessee shall be relieved of all of its obligations in
favor of Lessor with respect to such Units of Equipment, and (ii) Lessor shall
transfer all of its interest in such Units of Equipment to Lessee "AS IS, WHERE
IS," without any warranty, express or implied, from Lessor, other than the
absence of any liens or claims by or through Lessor. In the event Lessor and
Lessee are unable to agree on

                                       2
<PAGE>   3
the Fair Market Value of any Units of Equipment, Lessor and Lessee shall, at
Lessee's expense, select an independent appraiser to conclusively determine such
amount.

      B. RENEWAL OPTION. Lessee may elect, by delivering to Lessor an
End-of-Term Notice at least 90 days prior to the expiration of the Initial Term,
any Renewal Term, or any optional extension of the Initial Term or any Renewal
Term, to renew the Lease with respect to any or all Units of Equipment then
subject to such Lease (other than items of Software that may not be re-released
by Lessor under the terms of any applicable License Agreement) for an amount
equal to the Fair Rental Value of such Units of Equipment as of the end of the
Then Applicable Term. In the event of such an election, Lessee shall enter into
a mutually agreeable renewal agreement with Lessor ("Renewal Agreement") on or
before the last day of the Then Applicable Term confirming the Units of
Equipment as to which the Lease is to be renewed, the period for which the Lease
is to be renewed (the "Renewal Term"), and the amount of Rent and the times at
which such Rent is to be payable during the Renewal Term. In the event Lessor
and Lessee are unable to agree on the Fair Rental Value of any Units of
Equipment, Lessor and Lessee shall, at Lessee's expense, select an independent
appraiser to conclusively determine such amount.

      C. RETURN. Lessee may elect, by delivering to Lessor an End-of-Term Notice
at least 90 days prior to the expiration of the Initial Term, any Renewal Term
or any optional extension of the Initial Term or any Renewal Term, to return any
or all of the Units of Equipment then subject to such Lease in accordance with
Section 9 of this Master Agreement.

      D. OPTIONAL EXTENSION. Lessee may elect, by omitting to deliver to Lessor
an End-of-Term Notice at least 90 days prior to the expiration of the Initial
Term or any Renewal Term, to extend the Initial Term or such Renewal Term, as
the case may be. In that event, the Initial Term or such Renewal Term shall,
without any additional notice or documentation, be automatically extended for
successive calendar months with respect to all items of Equipment then subject
to such Lease through the end of the calendar month falling at least 90 days
after the date Lessee shall have delivered to Lessor an End-of-Term Notice with
respect to such Lease. For each calendar month that the Then Applicable Term of
such Lease is so extended, Lessee shall pay to Lessor Rent in an amount equal to
the monthly Rent payment in effect immediately prior to such extension (or the
appropriate pro rata portion of the Rent payment then in effect in the case of
Rent payable other than on a monthly basis), and all other provisions of this
Master Agreement and the applicable Schedule shall continue to apply.

      If Lessee shall have delivered to Lessor an End-of-Term Notice with
respect to a Lease, but shall have subsequently failed to comply with its
obligations arising from its elections specified therein (e.g., Lessee shall
have failed, on or before the last day of the Then Applicable Term (i) to pay
Lessor the purchase price for Equipment to be purchased in accordance with
Section 4.A above (ii) to execute a Renewal Agreement with respect to Equipment
as to which the Lease is to be renewed in accordance with Section 4.B above, or
(iii) to return to Lessor Equipment to be returned in accordance with Section
4.C above), then the Then Applicable Term of such Lease shall, without any
additional notice or documentation, be automatically extended for successive
calendar months with respect to all items of Equipment as to which Lessee shall
have so failed to comply with its obligations through the end of the calendar
month in which Lessee shall have complied with such obligations. For each
calendar month that the Then Applicable Term of any Lease is so extended, Lessee
shall pay to Lessor Rent in an amount equal to the monthly Rent payment in
effect immediately prior to such extension (or the appropriate pro rata portion
of the Rent payment then in effect in the case of Rent payable other than on a
monthly basis), and all other provisions of this Master Agreement and the
applicable Schedule shall continue to apply. Notwithstanding any of the
provisions of this Section 4 to the contrary, if any Lessee Default shall have
occurred and be continuing at any time during the last 90 days of the Then
Applicable Term of any Lease, Lessor may cancel any Renewal Term or optional or
other automatic extension of the Then Applicable Term immediately upon written
notice to Lessee.

5. RENT; LATE CHARGES; ADVANCE RENT. As rent ("Rent") for the Equipment under
any Lease and the Financed Items under any Financing, Lessee agrees to pay the
amounts specified in the applicable Schedule on the due dates specified in the
applicable Schedule. Lessee agrees to pay Lessor interest on any Rent payment or
other amount due hereunder that is not paid within 10 days of its due date, at
the rate of 1-1/2% per month (or such lesser rate as is the maximum rate
allowable under applicable law). Lessee shall pay to Lessor, with respect to
each Lease or Financing, the Advance Rent specified on the applicable Schedule,
if any. Any payment of Advance Rent shall be credited against the first Rent
payment payable by Lessee under the applicable Schedule and any excess Advance
Rent will be credited against the last Rent payment(s) payable by Lessee with
respect to the Initial Term of the applicable Lease or Financing. Advance Rent
shall be refunded to Lessee without interest only if Lessor declines to sign the
applicable Schedule.

6. LEASES AND FINANCINGS NON-CANCELABLE; NET LEASES; WAIVER OF DEFENSES TO
PAYMENT. IT IS SPECIFICALLY UNDERSTOOD AND AGREED THAT EACH LEASE AND FINANCING
HEREUNDER SHALL BE NON-CANCELABLE, AND THAT EACH LEASE HEREUNDER IS A NET LEASE.
LESSEE AGREES THAT IT HAS AN ABSOLUTE AND UNCONDITIONAL OBLIGATION TO PAY ALL
RENT AND OTHER AMOUNTS WHEN DUE. LESSEE IS NOT ENTITLED TO ABATE OR REDUCE RENT
OR ANY OTHER AMOUNT DUE, OR TO SET OFF ANY CHARGE AGAINST ANY SUCH AMOUNT.
LESSEE HEREBY WAIVES ANY RECOUPMENT, CROSS-CLAIM, COUNTERCLAIM OR ANY OTHER
DEFENSE AT LAW OR IN EQUITY TO ANY RENT PAYMENT OR OTHER AMOUNT DUE WITH RESPECT
TO ANY LEASE OR FINANCING, WHETHER ANY SUCH DEFENSE ARISES OUT OF THIS MASTER
AGREEMENT, ANY SCHEDULE, ANY CLAIM BY LESSEE AGAINST LESSOR, LESSOR'S ASSIGNEES
OR SUPPLIER, OR OTHERWISE. IF THE EQUIPMENT OR ANY FINANCED ITEM IS NOT PROPERLY
INSTALLED, DOES NOT OPERATE OR INTEGRATE AS REPRESENTED OR WARRANTED BY SUPPLIER
OR IS UNSATISFACTORY FOR ANY REASON WHATSOEVER, LESSEE SHALL MAKE ANY CLAIM ON
ACCOUNT THEREOF SOLELY AGAINST SUPPLIER AND SHALL NEVERTHELESS PAY ALL SUMS DUE
WITH RESPECT TO EACH LEASE AND EACH FINANCING.

7. ASSIGNMENT OF PURCHASE DOCUMENTS. Lessee assigns to Lessor all of Lessee's
right, title and interest in and to (a) the Equipment described in each
Schedule, and (b) the Purchase Documents relating to such Equipment. Such
assignment of the Purchase Documents is an assignment of rights only; nothing in
this Master Agreement shall be deemed to have relieved Lessee of any obligation
or liability under any of the Purchase Documents, except that, as between Lessee
and Lessor, Lessor shall pay for the Equipment within 30 days after Lessee's
delivery to Lessor of a properly completed and executed Acceptance Certificate
and all other documentation necessary to establish Lessee's acceptance of such
Equipment under the related Lease. Lessee represents and warrants that it has
reviewed and approved the Purchase Documents. In addition, if Lessor shall so
request, Lessee shall deliver to Lessor a document acceptable to Lessor whereby
Seller acknowledges and provides any required consent to such assignment. For
the avoidance of doubt, Lessee covenants and agrees that it shall at all times
during the Total Term of each Lease comply in all respects with the terms of any
License Agreement relating to any Equipment leased thereunder. IT IS ALSO
SPECIFICALLY UNDERSTOOD AND AGREED THAT NEITHER SUPPLIER NOR ANY SALESPERSON OF
SUPPLIER IS AN AGENT OF LESSOR, NOR ARE THEY AUTHORIZED TO WAIVE OR ALTER ANY
TERMS OF THIS MASTER AGREEMENT OR ANY SCHEDULE.

8. ASSIGNMENT OF SUPPLIER WARRANTIES. To the extent permitted, Lessor hereby
assigns to Lessee, for the Total Term of any Lease, all Equipment warranties
provided by any Supplier in the applicable Purchase Documents. Lessee shall have
the right to take any action it deems appropriate to enforce such warranties
provided such enforcement is pursued in Lessee's name and at its expense. In the
event Lessee is precluded from enforcing any such warranty in its name, Lessor
shall, upon Lessee's request, take reasonable steps to enforce such warranty. In
such circumstances, Lessee shall, promptly upon demand, reimburse Lessor for all
out-of-pocket expenses incurred by Lessor in enforcing the Supplier warranty.
Any recovery resulting from any such enforcement efforts shall be divided among
Lessor and Lessee as their interests may appear.

9. EQUIPMENT RETURN REQUIREMENTS. On or before the last day of the Total Term of
each Lease (and any other time Lessee is required to return Equipment to Lessor
under the terms of this Master Agreement or any Schedule), Lessee shall pack the
Equipment to be returned to Lessor in

                                       3
<PAGE>   4
accordance with the manufacturer's guidelines and deliver such Equipment to
Lessor at any destination within the continental United States designated by
Lessor. In the case of any item of Software to be returned to Lessor, Lessee
shall also deliver to Lessor the original Certificate of Authenticity issued by
the licensor of such Software, if any. Alternatively, Lessee may deliver any
such Certificate of Authenticity to Lessor on or at any time after the
Acceptance Date for such Software. All dismantling, packaging, transportation,
in-transit insurance and shipping charges shall be borne by Lessee. All
Equipment shall be returned to Lessor in the same condition and working order as
when delivered to Lessee, reasonable wear and tear excepted, and shall qualify
for maintenance service by the Supplier at its then standard rates for Equipment
of that age, if available. Lessee shall be responsible for, and shall reimburse
Lessor promptly on demand for, any cost incurred by Lessor to qualify the
Equipment for the Supplier's maintenance service or, if not available, to return
the Equipment to good working condition.

10. EQUIPMENT USE AND MAINTENANCE. Lessee is solely responsible for the
selection, installation, operation and maintenance of the Equipment and all
costs related thereto, including shipping charges. Lessee shall at all times
operate and maintain the Equipment in good working order, repair, condition and
appearance, and in accordance with the manufacturer's specifications and
recommendations. On reasonable prior notice to Lessee, Lessor and Lessors agents
shall have the right, during Lessee's normal business hours, to enter the
premises where the Equipment is located for the purpose of inspecting the
Equipment and observing its use. If Lessor shall have provided to Lessee any
tags or identifying labels, Lessee shall, at its expense, affix and maintain in
a prominent position on each item of Equipment such tags or labels to indicate
Lessor's ownership of the Equipment. Except in the case of PC Equipment and
Software, Lessee shall, at its expense, enter into and maintain and enforce at
all times during the Total Term of each Lease a maintenance agreement to service
and maintain the related Equipment, upon terms and with a provider reasonably
acceptable to Lessor.

11. EQUIPMENT OWNERSHIP; LIENS; LOCATION. As between Lessor and Lessee, Lessor
is the sole owner of the Equipment and has sole title thereto. Lessee shall not
make any representation to any third-party inconsistent with Lessor's sole
ownership of the Equipment. Lessee covenants that it will not pledge or
encumber the Equipment or Lessor's interest in the Equipment in any manner
whatsoever nor create or permit to exist any levy, lien or encumbrance thereof
or thereon except those created by or through Lessor. The Equipment shall remain
Lessor's personal property whether or not affixed to realty and shall not become
a fixture or be made to become a part of any real property on which it is placed
without Lessor's prior written consent. Lessee shall maintain the Equipment so
that it may be removed from any building in which it is placed without any
damage to the building or the Equipment. Lessee may relocate any Equipment from
the Equipment Location specified in the applicable Schedule to another of its
business locations within the United States upon prior written notice to Lessor
specifying the new Equipment Location, provided Lessee remains in possession and
control of the Equipment.

12. ALTERATIONS AND ADDITIONS TO EQUIPMENT. Lessee shall make no alterations or
additions to the Equipment, except those that (a) will not void any warranty
made by the Supplier of the Equipment, result in the creation of any security
interest, lien or encumbrance on the Equipment or impair the value or use of the
Equipment either at the time made or at the end of the Total Term of the
applicable Lease, and that are readily removable without damage to the Equipment
("Optional Additions"), or (b) are required by any applicable law, regulation or
order. All additions to the Equipment or repairs made to the Equipment, except
Optional Additions, become a part thereof and Lessor's property at the time
made; Optional Additions which have not been removed prior to the return of the
Equipment shall become Lessor's property upon such return.

13. INSURANCE. Lessee agrees to keep the Equipment insured at Lessee's expense
against all risks of loss from any cause whatsoever, including without
limitation, theft and damage. Lessee agrees that such insurance shall name
Lessor as a loss payee and cover not less than the Stipulated Loss Value of the
Equipment. Lessee also agrees that it shall carry commercial general liability
insurance in an amount not less than $2,000,000 total liability per occurrence
and cause Lessor and its affiliates to be named additional insureds under such
insurance. Each policy shall provide that the insurance cannot be canceled
without at least 30 days prior written notice to Lessor. Lessee shall provide to
Lessor (a) on or prior to the Acceptance Date for each Lease, and from time to
time thereafter, certificates of insurance evidencing such insurance coverage
throughout the Total Term of each Lease, and (b) upon Lessor's request, copies
of the insurance policies. If Lessee fails to provide Lessor with such evidence,
then Lessor will have the right, but not the obligation, to purchase such
insurance protecting Lessor at Lessee's expense. Lessee's expense shall include
the full premium paid for such insurance and any customary charges, costs or
fees of Lessor. Lessee agrees to pay such amounts in substantially equal
installments allocated to each Rent payment (plus interest on such amounts at
the rate of 1-1/2% per month or such lesser rate as is the maximum rate
allowable under applicable law).

14. RISK OF LOSS. In the event any Casualty Loss shall occur, on the next Rent
payment date Lessee shall, at its option (a) pay Lessor the Stipulated Loss
Value of the Equipment suffering the Casualty Loss, or (b) substitute and
replace each item of Equipment suffering the Casualty Loss with an item of
Substitute Equipment. If Lessee shall elect to pay the Stipulated Loss Value of
the Equipment suffering a Casualty Loss, upon Lessor's receipt in full of such
payment the applicable Lease shall terminate as it relates to such Equipment
and, except as provided in Section 27, Lessee shall be relieved of all
obligations under the applicable Lease as it relates to such Equipment. If
Lessee shall elect to replace Equipment suffering a Casualty Loss with items of
Substitute Equipment (i) the applicable Lease shall continue in full force and
effect without any abatement of Rent with such Substitute Equipment thereafter
being deemed to be Equipment leased thereunder, and (ii) Lessee shall deliver to
Lessor a bill of sale or other documentation, in either case in form and
substance satisfactory to Lessor, in which Lessee shall represent and warrant
that it has transferred to Lessor good and marketable title to all Substitute
Equipment, free and clear of all liens, encumbrances and claims of others. Upon
Lessor's receipt of such payment of Stipulated Loss Value in full, or such bill
of sale or other documentation, as the case may be, Lessor shall transfer to
Lessee all of Lessor's interest in the Equipment suffering the Casualty Loss "AS
IS, WHERE IS," without any warranty, express or implied, from Lessor, other than
the absence of any liens or claims by or through Lessor. In the event of any
repairable damage to any Equipment, the Lease shall continue with respect to
such Equipment without any abatement of Rent and Lessee shall at its expense
promptly cause such Equipment to be repaired to the condition it is required to
be maintained in pursuant to Section 10. Lessee shall notify Lessor of any
Casualty Loss or repairable damage to any Equipment as soon as reasonably
practicable after the date of any such occurrence.

15. TAXES. Lessor shall report and pay all Taxes now or hereafter imposed or
assessed by governmental body, agency or taxing authority upon the purchase,
ownership, delivery, installation, leasing, rental, use or sale of the
Equipment, the Rent or other charges payable hereunder, or otherwise upon or in
connection with any Lease or Financing, whether assessed on Lessor or Lessee,
other than any such Taxes required by-law to be reported and paid by Lessee.
Lessee shall promptly reimburse Lessor for all such Taxes paid by Lessor,
together with any penalties or interest in connection therewith attributable to
Lessee's acts or failure to act, excluding (a) Taxes on or measured by the
overall gross or net income or items of tax preference of Lessor, (b) as to any
Lease or the related Equipment, Taxes attributable to the period after the
return of such Equipment to Lessor, and (c) Taxes imposed as a result of a sale
or other transfer by Lessor of any portion of its interest in any Lease or
Financing or in any Equipment except for a sale or other transfer to Lessee or a
sale or other transfer occurring after and during the continuance of any Lessee
Default.

16. GENERAL INDEMNITY. Lessee shall indemnify and hold harmless Lessor, its
employees, officers, directors, agents and assignees and, if requested by
Lessor, defend Lessor, its employees, officers, directors, agents and assignees,
from and against any and all Claims arising directly or indirectly out of or in
connection with any matter involving this Master Agreement, the Equipment or any
Lease or Financing, including but not limited to (a) the selection, manufacture,
purchase, acceptance, rejection, ownership, delivery, lease, financing,
possession, maintenance, use, condition, return or operation of any Equipment or
Financed Items or the enforcement of Lessor's rights under any Lease or
Financing; (b) any latent defect or other defect in any Equipment or Financed
Item, whether or not discoverable by Lessor or by Lessee; (c) any patent,
trademark or copyright infringement involving any Equipment or Financed Item;
(d) the condition of any Equipment or Financed Item arising or existing at any
time during the Total Term of any Lease or the Term of any Financing; and (e)
any breach by Lessee of any representation, warranty or covenant contained in
any

                                       4
<PAGE>   5
Fundamental Agreement. Notwithstanding the foregoing, Lessee shall have no
obligation to indemnify or defend against any Claim arising solely as a result
of Lessor's gross negligence or willful misconduct.

17. TAX BENEFIT INDEMNITY. Each Lease is entered into on the assumption that
Lessor is the owner of the Equipment for tax purposes and is entitled to certain
federal and state tax benefits available to an owner of Equipment (collectively,
"Tax Benefits"), including without limitation, accelerated cost recovery system
deductions for 5-year property and deductions for interest incurred by Lessor to
finance the purchase of Equipment available under the Code. Lessee represents,
warrants and covenants to Lessor that (a) Lessee is not a tax-exempt entity
(as defined in Section 168(h) of the Code), (b) all Equipment will be used
solely within the United States, and (c) Lessee will take no position
inconsistent with the assumption that Lessor is the owner of the Equipment for
federal and state tax purposes. If, due to any act or omission of Lessee or any
party acting through Lessee, or the breach or inaccuracy of any representation,
warranty or covenant of Lessee contained in any Fundamental Agreement, Lessor
reasonably determines that it cannot claim, is not allowed to claim, loses or
must recapture any or all of the Tax Benefits otherwise available with respect
to the Equipment subject to any Lease (a "Tax Loss"), then Lessee shall,
promptly upon demand, pay to Lessor an amount sufficient to provide Lessor the
same after-tax rate of return and aggregate after-tax cash flow through the end
of the Then Applicable Term of such Lease that Lessor would have realized but
for such Tax Loss.

18. COVENANT OF QUIET ENJOYMENT. So long as no Lessee Default exists, and no
event shall have occurred and be continuing which, with the giving of notice or
the passage of time or both, would constitute a Lessee Default, neither Lessor
nor any party acting or claiming through Lessor, by assignment or otherwise,
will disturb Lessee's quiet enjoyment of the Equipment during the Total Term of
the related Lease.

19. DISCLAIMERS AND LESSEE WAIVERS. LESSEE LEASES THE EQUIPMENT FROM LESSOR "AS
IS, WHERE IS". IT IS SPECIFICALLY UNDERSTOOD AND AGREED THAT (A) EXCEPT AS
EXPRESSLY SET FORTH IN SECTION 18, LESSOR MAKES ABSOLUTELY NO REPRESENTATIONS OR
WARRANTIES WHATSOEVER, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY
REPRESENTATION OR WARRANTY WITH RESPECT TO THE DESIGN, COMPLIANCE WITH
SPECIFICATIONS, QUALITY, OPERATION, OR CONDITION OF ANY EQUIPMENT OR FINANCED
ITEMS (OR ANY PART THEREOF), THE MERCHANTABILITY OR FITNESS OF EQUIPMENT OR
FINANCED ITEMS FOR A PARTICULAR PURPOSE, OR ISSUES REGARDING PATENT
INFRINGEMENT, TITLE AND THE LIKE; (B) LESSOR SHALL NOT BE DEEMED TO HAVE MADE,
BE BOUND BY OR LIABLE FOR, ANY REPRESENTATION, WARRANTY OR PROMISE MADE BY THE
SUPPLIER OF ANY EQUIPMENT OR FINANCED ITEMS (EVEN IF LESSOR IS AFFILIATED WITH
SUCH SUPPLIER); (C) LESSOR SHALL NOT BE LIABLE FOR ANY FAILURE OF ANY EQUIPMENT
OR FINANCED ITEMS OR ANY DELAY IN THE DELIVERY OR INSTALLATION THEREOF; (D)
LESSEE HAS SELECTED ALL EQUIPMENT AND FINANCED ITEMS WITHOUT LESSOR'S
ASSISTANCE; AND (E) LESSOR IS NOT A MANUFACTURER OF ANY EQUIPMENT. IT IS FURTHER
AGREED THAT LESSOR SHALL HAVE NO LIABILITY TO LESSEE, LESSEE'S CUSTOMERS, OR ANY
THIRD PARTIES FOR ANY INCIDENTAL, INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES
ARISING OUT OF THIS MASTER AGREEMENT OR ANY SCHEDULE OR CONCERNING ANY EQUIPMENT
OR FINANCED ITEMS, OR FOR ANY DAMAGES BASED ON STRICT OR ABSOLUTE TORT LIABILITY
OR, EXCEPT TO THE EXTENT CONSTITUTING A LESSOR DEFAULT, LESSOR'S NEGLIGENCE;
PROVIDED, HOWEVER, THAT NOTHING IN THIS MASTER AGREEMENT SHALL DEPRIVE LESSEE OF
ANY RIGHTS IT MAY HAVE AGAINST ANY PERSON OTHER THAN LESSOR. LESSOR AND LESSEE
AGREE THAT THE LEASES AND THE FINANCINGS SHALL BE GOVERNED BY THE EXPRESS
PROVISIONS OF THIS MASTER AGREEMENT AND THE OTHER FUNDAMENTAL AGREEMENTS AND NOT
BY THE CONFLICTING PROVISIONS OF ANY OTHERWISE APPLICABLE LAW. ACCORDINGLY, TO
THE EXTENT PERMITTED BY APPLICABLE LAW, LESSEE WAIVES THE RIGHT TO (1) CANCEL OR
REPUDIATE THIS MASTER AGREEMENT, (2) REVOKE ACCEPTANCE OF OR REJECT THE
EQUIPMENT, (3) CLAIM A SECURITY INTEREST IN THE EQUIPMENT, (4) SELL OR DISPOSE
OF THE EQUIPMENT UPON REJECTION OR REVOCATION, (5) SEEK "COVER" IN SUBSTITUTION
FOR A LEASE FROM LESSOR, AND (6) CLAIM AN AGENCY RELATIONSHIP BETWEEN SUPPLIER
AND LESSOR.

20. LESSEE WARRANTIES. Lessee represents, warrants and covenants to Lessor that:
(a) ALL EQUIPMENT WILL BE USED FOR BUSINESS PURPOSES ONLY AND NOT FOR PERSONAL,
FAMILY OR HOUSEHOLD PURPOSES; (b) Lessee is duly organized, validly existing and
in good standing under applicable law; (c) Lessee has the power and authority to
enter into each of the Fundamental Agreements; (d) all Fundamental Agreements
are enforceable against Lessee in accordance with their terms and do not violate
or create a default under any instrument or agreement binding on Lessee: (e)
there are no pending or threatened actions or proceedings before any court or
administrative agency that could have a material adverse effect on Lessee or any
Fundamental Agreement, unless such actions are disclosed to Lessor and consented
to in writing by Lessor; (x) Lessee shall comply in all material respects with
all laws and regulations the violation of which could have a material adverse
effect upon the Equipment or Lessee's performance of its obligations under any
Fundamental Agreement; (g) each Fundamental Agreement shall be effective against
all creditors of Lessee under applicable law, including fraudulent conveyance
and bulk transfer laws, and shall raise no presumption of fraud; and (h) all
financial statements and other related information furnished by Lessee shall be
prepared in accordance with generally accepted accounting principles and shall
fairly present Lessee's financial position as of the dates given on such
statements.

21. DEFAULT. Any of the following shall constitute a default by Lessee (a
"Lessee Default") under this Master Agreement and all Leases and Financings: (a)

exercise one or more of the following remedies: (a) declare all amounts due and
to become due under any or all Leases and Financings to be

                                       5
<PAGE>   6
immediately due and payable; or (b) terminate this Master Agreement or any Lease
or Financing; or (c) take possession of, or render unusable, any Equipment
wherever the Equipment may be located, without demand or notice and without any
court order or other process of law, but not in violation of the law, in
accordance with Lessee's reasonable security procedures, and no such action
shall constitute a termination of any Lease; or (d) require Lessee to deliver
the Equipment to a location specified by Lessor; or (e) declare the Stipulated
Loss Value for any or all Equipment to be due and payable as liquidated damages
for loss of a bargain and not as a penalty and in lieu of any further Rent
payments under the applicable Lease or Leases; or (x) proceed by court action to
enforce performance by Lessee of any Lease or Financing and/or to recover all
damages and expenses incurred by Lessor by reason of any Lessee Default; or (g)
terminate any other agreement that Lessor may have with Lessee; or (h) exercise
any other right or remedy available to Lessor at law or in equity. In the event
of a Lessee Default, Lessee shall pay Lessor all reasonable costs and expenses
that Lessor may incur to maintain, safeguard or preserve the Equipment, and
other reasonable expenses incurred by Lessor in enforcing any of the terms,
conditions or provisions of this Master Agreement (including reasonable legal
fees and collection agency costs). Upon repossession or surrender of any
Equipment, Lessor shall lease, sell or otherwise dispose of the Equipment in a
commercially reasonable manner and apply the net proceeds thereof to the amounts
owed to Lessor hereunder, which shall be the Stipulated Loss Value with regard
to such but only after deducting (i) in the case of a sale, the estimated Fair
Market Value of the Equipment sold as of the scheduled expiration of the Then
Applicable Term of the related Lease, (ii) in the case of a lease, the rent due
for any period beyond the scheduled expiration of the Then Applicable Term of
the related Lease, and (iii) in either case, all expenses (including reasonable
legal fees and costs) reasonably incurred by Lessor in connection therewith;
provided, however, that lessee shall remain liable to Lessor for any deficiency
that remains after any sale or lease of such Equipment. Any proceeds of any sale
or lease of such Equipment in excess of the amounts owed to Lessor hereunder
shall be retained by Lessor. Lessee agrees that with respect to any notice of a
sale required by law to be given, 10 days' notice shall constitute reasonable
notice. Upon payment of all past due Rent and the Stipulated Loss Value as
provided in clause (e) above, together with interest at the rate of 1-1/2 % per
month (or such lesser rate as is the maximum rate allowable under applicable
law) from the date declared due until paid, Lessor will transfer to Lessee all
of Lessors interest in the Equipment for which such Rent and Stipulated Loss
Value has been paid, which transfer shall be on an "AS IS, WHERE IS" basis,
without any warranty, express or implied, from Lessor, other than the absence of
any liens or claims by or through Lessor. These remedies are cumulative of every
other right or remedy given hereunder or now or hereafter existing at law or in
equity or by statute or otherwise, and may be enforced concurrently therewith or
from time to time.

      If a Lessor Default occurs, Lessee's sole and exclusive remedy shall be to
recover by appropriate legal proceedings any direct damages suffered by Lessee
as a result of such Lessor Default and any reasonable and necessary expenses
(including, without limitation, court costs and reasonable legal fees) incurred
by Lessee in connection therewith.

23. PERFORMANCE OF LESSEE'S OBLIGATIONS. If Lessee fails to perform any of its
obligations hereunder, Lessor may perform any act or make any payment that
Lessor deems reasonably necessary for the maintenance and preservation of the
Equipment and Lessors interests therein; provided, however, that the performance
of any act or payment by Lessor shall not be deemed a waiver of, or release
Lessee from, the obligation at issue. All sums so paid by Lessor, together with
expenses (including legal fees and costs) incurred by Lessor in connection
therewith, shall be paid to Lessor by Lessee immediately upon demand.

24. TRUE LEASE; SECURITY INTEREST; MAXIMUM RATE. Each Lease is intended to be a
"Finance Lease" as defined in Article 2A of the UCC, and Lessee hereby
authorizes Lessor to file a financing statement to give public notice of
Lessor's ownership of the Equipment. Lessee, by its execution of each Schedule,
acknowledges that Lessor has informed it that (a) the identity of Seller is set
forth in the applicable Schedule, (b) Lessee is entitled under Article 2A to the
promises and warranties, including those of any third party, provided to Lessor
in connection with, or as a part of, the applicable Purchase Documents, and (c)
Lessee may communicate with Seller and receive an accurate and complete
statement of the promises and warranties, including any disclaimers and
limitations of them or of remedies. If (i) notwithstanding the express intention
of Lessor and Lessee to enter into a true lease, any Lease is ever deemed by a
court of competent jurisdiction to be a lease intended for security, or (ii)
Lessor and Lessee enter into a Lease with the intention that it be treated as a
lease intended as security by so providing in the applicable Schedule, or (iii)
Lessor and Lessee enter into a Financing, then to secure payment and performance
of Lessee's obligations under this Master Agreement and all Leases and
Financings, Lessee hereby grants Lessor a purchase money security interest in
the related Equipment and Financed Items and in all attachments, accessories,
additions, substitutions, products, replacements, rentals and proceeds
(including, without limitation, insurance proceeds) thereto as well as a
security interest in any other equipment financed pursuant to this Master
Agreement or any other agreement between Lessor and Lessee (collectively, the
"Collateral"). In any such event, notwithstanding any provisions contained in
this Master Agreement or in any Schedule, neither Lessor nor any Assignee shall
be entitled to receive, collect or apply as interest any amount in excess of the
maximum rate or amount permitted by applicable law. In the event Lessor or any
Assignee ever receives, collects or applies as interest any amount in excess of
the maximum amount permitted by applicable law, such excess amount shall be
applied to the unpaid principal balance and any remaining excess shall be
refunded to Lessee. In determining whether the interest paid or payable under
any specific contingency exceeds the maximum rate or amount permitted by
applicable law, Lessor and Lessee shall, to the maximum extent permitted under
applicable law, characterize any non-principal payment as an expense or fee
rather than as interest, exclude voluntary prepayments and the effect thereof,
and spread the total amount of interest over the entire term of this Master
Agreement and all Leases and Financings.

25. ASSIGNMENT. Lessor shall have the unqualified right to sell, assign, pledge,
transfer, mortgage or otherwise convey any part of its interest in this Master
Agreement, any Schedule or any Equipment, in whole or in part, without prior
notice to or the consent of Lessee. If any Lease is assigned, Lessee shall (a)
unless otherwise specified by Lessor and the Assignee, pay all amounts due under
the applicable Schedule to such Assignee, notwithstanding any defense, setoff or
counterclaim whatsoever that Lessee may have against Lessor or Assignee; (b) not
permit the applicable Schedule to be amended or the terms thereof waived without
the prior written consent of the Assignee; (c) not require the Assignee to
perform any obligations of Lessor, other than those that are expressly assumed
in writing by such Assignee; and (d) execute such acknowledgments thereto as may
be requested by Lessor or the Assignee. It is further agreed that (i) each
Assignee shall be entitled to all of Lessor's rights, powers and privileges
under the applicable Lease or Financing, to the extent assigned; (ii) any
Assignee may reassign its rights and interests under the applicable Lease or
Financing with the same force and effect as the assignment described herein; and
(iii) any payments received by the Assignee from Lessee with respect to the
assigned portion of the Lease or Financing shall, to the extent thereof,
discharge the obligations of Lessee to Lessor with respect to the assigned
portion of the Lease or Financing. Lessee acknowledges that any assignment or
transfer by Lessor or any Assignee shall not materially change Lessee's
obligations under the assigned Lease or Financing.

      Upon Lessor's prior written consent, which shall not be unreasonably
withheld, Lessee may sublet the Equipment to another end user other than another
leasing company or other competitor of Lessor. No such sublease shall relieve
Lessee of its obligations under the Lease and Lessee shall be responsible for
all costs and expenses associated with such sublease, including, without
limitation, additional Taxes or any Tax Loss suffered by Lessor. Lessee may
permit use of the Equipment by its affiliates or independent contractors at the
Equipment Location provided it does not relinquish possession and control of the
Equipment. Lessee may not assign, transfer or otherwise dispose of this Master
Agreement, any Lease or Financing, any Equipment or any interest therein.

26. FURTHER ASSURANCES. Lessee agrees to promptly execute and deliver to Lessor
such further documents and take such further action as Lessor may require in
order to more effectively carry out the intent and purpose of this Master
Agreement and any Schedule. Without limiting the generality of the foregoing,
Lessee agrees (a) to furnish to Lessor from time to time, its certified
financial statements, officer's certificates and appropriate resolutions,
opinions of counsel and such other information and documents as Lessor may
reasonably request, and (b) to execute and timely deliver to Lessor any
financing statements or other documents that Lessor deems necessary to perfect
or protect Lessor's security interest in the Collateral or to evidence Lessor's
interest in the Equipment. If Lessee fails to execute any document referred to
in clause (b) of the preceding sentence, Lessor or Lessor's agent is hereby
authorized to sign and file the same as Lessee's agent.

                                       6
<PAGE>   7
It is also agreed that Lessor or Lessor's agent may file as a financing
statement, any lease document (or copy thereof, where permitted by law) that
Lessor deems appropriate to perfect or protect Lessor's security interest in the
Collateral or to evidence Lessor's interest in the Equipment. Upon demand,
Lessee will promptly reimburse Lessor for any filing or recordation fees or
expenses (including legal fees and costs) incurred by Lessor in perfecting or
protecting its interests in the Equipment.

27. TERM OF MASTER AGREEMENT; SURVIVAL. This Master Agreement shall commence and
be effective upon the execution hereof by both parties and shall continue in
effect until terminated by either party by 30 days' prior written notice to the
other. However, no termination of this Master Agreement pursuant to the
preceding sentence shall be effective with respect to any Lease or Financing
that commenced prior to such termination until the expiration or termination of
such Lease or Financing and the satisfaction by Lessee of all of its obligations
hereunder with respect thereto. All representations, warranties and covenants
made by Lessee hereunder shall survive the termination of this Master Agreement
and shall remain in full force and effect. All of Lessor's rights, privileges
and indemnities under this Master Agreement or any Lease or Financing, to the
extent they are fairly attributable to events or conditions occurring or
existing on or prior to the expiration or termination of such Lease or
Financing, shall survive such expiration or termination and be enforceable by
Lessor and Lessor's successors and assigns.

28. WAIVER OF JURY TRIAL. LESSEE AND LESSOR HEREBY EXPRESSLY WAIVE ANY RIGHT TO
DEMAND A JURY TRIAL WITH RESPECT TO ANY ACTION OR PROCEEDING INSTITUTED BY
LESSOR OR LESSEE IN CONNECTION WITH THIS MASTER AGREEMENT OR ANY FUNDAMENTAL
AGREEMENT.

29. NOTICES. All notices, requests, demands, waivers and other communications
required or permitted to be given under this Master Agreement or any other
