                                   JACOM GROUP
                    560 ROUTE 303, ORANGEBURG, NEW YORK 10962

                                                              Lease Number  2017

                             MASTER LEASE AGREEMENT

This agreement is made the 2ND day of MARCH, 2000 between Jacom Computer
Services, Inc., its principal office at 560 Route 303, Orangeburg, New York
10962 (the "Lessor") and SCREAMING MEDIA.COM INC., 601 West 26 Street, New York,
N.Y. 10001 (the "Lessee").

1.     LEASE.

Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor, the items
of personal property (the "Equipment") described in an Equipment Schedule or
Schedules executed and delivered by Lessor and Lessee concurrently with this
Agreement or subsequent thereto. Neither Lessor nor Lessee shall have any
obligations hereunder until the execution and delivery of such Equipment
Schedule or Schedules. Each Equipment Schedule (which shall be in the form
annexed hereto) shall constitute a separate lease and shall be binding, when
executed by the parties hereto, upon the parties, their successors, legal
representatives and permitted assigns. The terms and conditions contained herein
(including the Supplements, if any annexed hereto) and in such Equipment
Schedule or Schedules shall govern the leasing and use of the Equipment.

2.     ADDITIONAL DEFINITIONS.

(a)    The "Installation Date" means the date on which the Equipment is
       installed at Lessee's site.

(b)    The "Commencement Date" means, as to the Equipment designated on any
       Equipment Schedule where the Installation Date for such Equipment falls
       on the first day of the month, that date, and in any other case, the
       first day of the month following the month in which such Installation
       Date falls.

3.     TERM OF LEASE.

(a)    The term of this Agreement, as to all Equipment designated on any
       Equipment Schedule, shall commence on the Installation Date for such
       Equipment, and shall continue for an initial period ending that number of
       months from the applicable Commencement Date (the "Initial Period");
       thereafter, the term of this Agreement for all such Equipment shall be
       automatically extended for successive three-month periods unless and
       until terminated by either party giving to the other not less than six
       months prior written notice. Any such termination shall be effective only
       on the last day of the Initial Period or the last day of any such
       successive

<PAGE>   2

       periods. No Equipment Schedule may be terminated with respect to less
       than all items of Equipment identified therein.

(b)    Any notice of termination given by either party under this Agreement or
       under any Supplement annexed hereto may not be revoked without the
       written consent of the other party.

4.     RENTALS.

As to all Equipment, the monthly rental payable by Lessee to Lessor is as set
forth in the applicable Schedule. Rental shall begin on the Installation Date
and shall be due and payable by Lessee in advance on the first day of each
month. If the Installation Date does not fall on the first day of a month, the
first payment shall be pro rata portion of the monthly rental, calculated on a
30-day basis, due and payable on the Installation Date. In addition to the
monthly rental set forth in the Schedule, Lessee shall pay to Lessor an amount
equal to all taxes paid, payable or required to be collected by Lessor, however
designated, which are levied or based on such rental, on this Agreement, or on
the Equipment or its use, lease operation, control, or value, including without
limitation, state and local privilege or excise taxes based on gross revenue,
any penalties or interest in connection therewith or taxes or amounts in lieu
thereof paid or payable by Lessor in respect of the foregoing, but excluding
taxes based on Lessor's net income. Personal property taxes on the Equipment
shall be paid by Lessee. Lessee agrees to file, on behalf of Lessor, all
required property tax returns and reports concerning the Equipment with all
appropriate governmental agencies, and, within not more than 45 days after the
due date of such filing, to send Lessor confirmation of such filing.

Interest on any past due payment shall accrue at the rate of 1 3/4% per month,
(including any fraction thereof), or if such rate shall exceed the maximum rate
allowed by law, then at such maximum rate, and shall be payable on demand.
Charges for taxes, penalties and interest shall be promptly paid by Lessee when
invoiced by Lessor.

5.     INSTALLATION AND USE OF EQUIPMENT.

(a)    Lessee will provide the required suitable electric current to operate the
       Equipment and/or suitable place of installation for the Equipment with
       all appropriate facilities as specified by the manufacturer.

(b)    Subject to the terms of this Agreement, Lessee shall be entitled to
       unlimited usage of the Equipment without extra charge by Lessor and may
       sell time on the Equipment to third parties.

(c)    Lessee will at all times keep the Equipment in its sole possession and
       control. The Equipment shall not be moved from the location stated in the
       Equipment Schedules without the prior written consent of Lessor.

<PAGE>   3

(d)    After prior notice to Lessor, Lessee may, at its own expense, make
       alterations in or add attachments to the Equipment, provided that such
       alterations or attachments do not decrease the value of the Equipment or
       interfere with the normal and satisfactory operation or maintenance of
       the Equipment or with Lessee's ability to obtain and maintain the
       maintenance contract required by this Agreement. Unless Lessor shall
       otherwise agree in writing, all such alterations and attachments shall be
       and become the property of Lessor or, at the option of Lessee, shall be
       removed by Lessee and the Equipment restored at Lessee's expense to its
       original condition, reasonable wear and tear only excepted.

6.     MAINTENANCE AND REPAIRS.

(a)    Lessee shall, during the continuance of this Agreement, at its expense,
       keep the Equipment in good working order and condition and make all
       necessary adjustments, repairs and replacements thereto. Lessee shall not
       use or permit the Equipment to be used for any purpose for which, in the
       opinion of manufacturer, the Equipment is not designed or reasonably
       suitable.

(b)    Without limiting the generality of the foregoing, Lessee shall, during
       the continuance of this Agreement, at its own expense, enter into and
       maintain in force a contract with the manufacturer (or other qualified
       service organization approved in writing by both parties) covering at
       least prime shift maintenance of each item of Equipment. Such contract as
       to each item shall commence upon expiration of the warranty period, if
       any, relating to such items. Lessee shall furnish Lessor with a copy of
       such contract(s) upon demand.

(c)    At the termination of this Agreement, Lessee shall, at its expense,
       return the Equipment to Lessor (at the location designated by Lessor
       within the continental United States) in the same operating order,
       repair, condition and appearance as on the Installation Date, reasonable
       wear and tear only excepted with all engineering changes prescribed by
       the manufacturer prior thereto incorporated therein, and Lessee shall
       arrange and pay for such repairs (if any) as are necessary for the
       manufacturer to accept the equipment under contract maintenance at its
       then standard rates.

(d)    Lessee shall comply with all governmental laws, regulations and
       requirements, and all insurance requirements, if any, with respect to the
       use, maintenance and operation of the Equipment.

7.     OWNERSHIP AND INSPECTION.

(a)    The Equipment shall at all times remain the property of the Lessor.
       Lessor may affix or request Lessee to affix tags, decals or plates to the
       Equipment indicating Lessor's ownership, and Lessee shall not permit
       their removal or concealment.

(b)    It is the intention and understanding of both Lessor and Lessee that the
       Equipment shall be

<PAGE>   4

       and at all times remain separately identifiable personal property. Lessee
       shall not permit the Equipment to be installed in, or used, stored or
       maintained with, any personal property in such manner or under such
       circumstances that such Equipment might be or become an accession to or
       confused with such other personal property; provided, however, that the
       use or maintenance in accordance with normal operating procedures of
       Lessee of the Equipment with any other computer equipment owned by or
       leased to Lessee shall not be a violation of the foregoing provisions of
       this sentence. Lessee shall not permit the Equipment to be installed in
       or used, stored, or maintained with, any real property in such a manner
       or under such circumstances that any person might acquire any rights in
       such Equipment paramount to the rights of Lessor by reason of such
       Equipment being deemed to be real property or a fixture thereon.

(c)    Lessee shall keep the Equipment free and clear of all liens and
       encumbrances. Lessee shall not assign this agreement or any of its rights
       hereunder or sublease the Equipment without the prior written consent of
       Lessor, except that Lessee may, at its expense, upon prior written notice
       to Lessor, assign this Agreement or sublease the Equipment to any parent
       or subsidiary corporation, or to a corporation which shall have acquired
       all or substantially all of the property of Lessee by merger,
       consolidation or purchase. No permitted assignment or sublease shall
       relieve Lessee of any of its obligations hereunder.

(d)    Lessor or its agents shall have free access to the Equipment at all
       reasonable times for the purpose of inspection and for any other purpose
       contemplated in this Agreement.

(e)    Lessee shall immediately notify Lessor of all details concerning any
       damage or loss arising out of the improper manufacture, functioning or
       operation of the Equipment.

8.     WARRANTIES.

(a)    Lessor shall, at the request and expense of Lessee, enforce for the
       benefit of Lessee any rights which Lessor shall be entitled to enforce
       against the manufacturer in respect of the Equipment.

(b)    EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED HEREIN, THERE ARE NO
       REPRESENTATIONS OR WARRANTIES OF ANY KIND EXPRESS OR IMPLIED, WITH
       RESPECT TO THE CONDITION OR PERFORMANCE OF THE EQUIPMENT, ITS
       MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, OR WITH RESPECT TO
       PATENT INFRINGEMENT OR THE LIKE. LESSOR SHALL HAVE NO LIABILITY TO LESSEE
       FOR ANY CLAIM, LOSS OR DAMAGE OF ANY KIND OR NATURE WHATSOEVER, NOR SHALL
       THERE BE ANY ABATEMENT OF RENTAL, ARISING OUT OF OR IN CONNECTION WITH
       (i) THE DEFICIENCY OR INADEQUACY OF THE EQUIPMENT FOR ANY PURPOSE,
       WHETHER OR NOT KNOWN OR DISCLOSED TO LESSOR, (ii) ANY DEFICIENCY OR
       DEFECT IN THE EQUIPMENT, (iii) THE USE OR PERFORMANCE OF THE EQUIPMENT,
       (iv) ANY

<PAGE>   5

       INTERRUPTION OR LOSS OF SERVICE OR USE OF THE EQUIPMENT, OR (v) ANY LOSS
       OF BUSINESS OR OTHER CONSEQUENTIAL LOSS OR DAMAGE WHETHER OR NOT
       RESULTING FROM ANY OF THE FOREGOING. LESSEE WILL DEFEND, INDEMNIFY AND
       HOLD LESSOR HARMLESS AGAINST ANY AND ALL CLAIMS, DEMANDS AND LIABILITIES
       ARISING OUT OF OR IN CONNECTION WITH THE DESIGN, MANUFACTURE, POSSESSION
       OR OPERATION OF THE EQUIPMENT.

9.     SECURITY INTEREST.

(a)    In the event that Lessor transfers or assigns or grants a security
       interest in all or any part of its rights in this Agreement, the
       Equipment and/or sums payable hereunder to the third party, whether as
       collateral security for any loans or advances made or to be made to
       Lessor by such third party or otherwise, Lessee, upon receipt of notice
       of any such transfer or assignment and instructions from Lessor, shall
       pay its obligations hereunder or amounts equal thereto to the third party
       (or to any other party designated by the third party), and Lessee's
       obligations hereunder shall be absolute and unconditional and shall not
       be subject to any abatement, reduction, recoupment, defense, offset or
       counterclaim available to Lessee against Lessor for any reason
       whatsoever; nor, except as otherwise expressly provided herein, shall
       this Agreement terminate, or the respective obligations of Lessor or
       Lessee be otherwise affected, by reason of any defect in the Equipment,
       condition, design, operation or fitness for use thereof or any loss or
       destruction of the Equipment or any part thereof, the prohibition of or
       other restriction against Lessee's use of the Equipment, the interference
       with such use by any private person or entity, or by reason of any
       failure by Lessor to perform any of its obligations herein contained, or
       by reason of any other indebtedness or liability, howsoever and whenever
       arising, of Lessor to Lessee or to any other person, firm or corporation
       or to any governmental authority or for any other cause whether similar
       or dissimilar to the foregoing, any present or future law to the contrary
       notwithstanding, it being the intention of the parties hereto that the
       Rental payable by Lessee hereunder shall continue to be payable in all
       events and at the times herein provided, except as otherwise expressly
       provided for herein.

(b)    On the Installation Date as to each Equipment Schedule, Lessee will
       furnish to Lessor, and/or its assignee, a certificate signed by an
       officer of Lessee to the effect that: Lessee has full power and authority
       to enter into this Agreement; this Agreement has been duly authorized,
       executed and delivered by Lessee and is its valid and binding obligation,
       enforceable in accordance with its terms; no approval, consent, or
       withholding of objection is required from any governmental authority with
       respect to the entering into or performance of this Agreement by Lessee;
       the entering into or performance of this Agreement by Lessee does not and
       will not violate a judgment, order, law or regulation applicable to
       Lessee or any provision of Lessee's certificate of incorporation or
       by-laws or result in a breach of, or constitute a default under, or
       result in the creation of any lien, charge, security interest or other
       encumbrance upon any assets of Lessee or on the Equipment or this
       Agreement pursuant to, any indenture, mortgage, deed of trust, bank loan,
       credit agreement or other
<PAGE>   6
       instrument to which Lessee is a party or by which it or its assets may be
       bound; the Equipment is located at Lessee's facility as shown on the
       Schedule; the Equipment has been and is then operating to the
       satisfaction of Lessee; Lessee has no right, title or interest in the
       Equipment or any part thereof except the rights, title and interest
       therein as Lessee thereof under this Agreement; and that, on the
       Installation Date, this Agreement is in full force and effect, neither
       party is in default hereunder, and Lessee's obligations hereunder are
       subject to no defenses, set offs or counterclaims. In addition, Lessee
       agrees promptly to execute and deliver to Lessor standard form UCC-l
       financing statements (to be filed for information purposes only) as well
       as such other agreements, documents, instruments and certificates as
       Lessor may reasonably request (including, without limitation, an opinion
       of counsel and certified copies of Board resolutions, both in form and
       substance satisfactory to Lessor) in order to effect Lessor's purchase of
       the Equipment or financing thereof.

10.    MISCELLANEOUS CHARGES.

Except as otherwise specifically provided in this Agreement, it is understood
and agreed that this is a net lease, and that, as between Lessor and Lessee,
Lessee shall be responsible for all costs and expenses of every nature
whatsoever arising out of or in connection with or related to this Agreement or
the Equipment (such as, but not limited to, transportation in and out,
transportation insurance, rigging, drayage, packing, installation and disconnect
charges).

11.    RISK OF LOSS ON LESSEE.

Lessee shall obtain and maintain from the time Lessee executes a document
evidencing physical receipt of the Equipment and for the entire term of this
Agreement, at its own expense, property damage and liability insurance and
insurance against loss or damage to the Equipment including, without limitation,
loss by fire (including so-called extended coverage) theft and such other risks
of loss as are customarily insured against the type of Equipment leased
hereunder by any businesses in which Lessee is engaged, in such amounts, in such
form and with such insurers as shall be satisfactory to Lessor; provided,
however, that the amount of insurance against loss or damage to the Equipment
shall not be less than the greater of the full replacement value of the
Equipment or the installments of rent then remaining unpaid hereunder plus any
renewal or purchase options contained herein. Each insurance policy will name
Lessee as an insured and Lessor as an additional insured and loss payee thereof
as Lessor's interest may appear, and shall contain a clause requiring the
insurer to give Lessor at least l0 days' prior written notice of any alteration
in the terms of such policy or of the cancellation thereof. Lessee shall furnish
to Lessor a certificate of insurance or other evidence satisfactory to Lessor
that such insurance coverage is in effect provided, however, that Lessor shall
be under no duty either to ascertain the existence of or to examine such
insurance policy or to advise Lessee in the event such insurance coverage shall
not comply with the requirements hereof. Lessee further agrees to give Lessor
prompt notice of any damage to, or loss of, the Equipment, or any part thereof.
Lessor shall be named as the Loss Payee on such policies, which shall be written
by an insurance company of recognized responsibility. Lessee agrees to insure
the interest of any third party (referred to in Paragraph 9 of this Agreement)
under a standard mortgagee
<PAGE>   7
clause. Evidence of such insurance coverage shall be furnished to Lessor upon
demand.

If any item of Equipment is rendered unusable as a result of any physical damage
to, or destruction of, the Equipment, the Lessee shall give Lessor immediate
notice thereof and this Agreement shall continue in full force and effect
without any abatement of rental. Lessee shall determine, within fifteen (15)
days after the date of occurrence of such damage or destruction, whether such
item of Equipment can be repaired. In the event Lessee determines that such item
of Equipment can be repaired, Lessee, at its expense, shall cause such item of
Equipment to be promptly repaired. In the event Lessee determines that the item
of Equipment cannot be repaired, Lessee, at its expense, shall promptly replace
such item of Equipment and convey title to such replacement to Lessor free of
all liens and encumbrances, and this Lease shall continue in full force and
effect as though such damage or destruction had not occurred. All proceeds of
insurance received by Lessor or Lessee under the policy referred to in the
preceding paragraph of this paragraph shall be applied toward the cost of any
such repair or replacement.

12.    INDEMNIFICATION.

Lessee hereby agrees to assume liability for, and does hereby agree to
indemnify, protect, save and keep harmless Lessor and its respective successors,
assigns, legal representatives, agents and servants, from and against, any and
all liabilities, obligations, losses, damages, penalties, claims, actions,
suits, costs, expenses or disbursements (including legal fees and expenses) of
any kind and nature whatsoever which may be imposed on, incurred by or asserted
against Lessor or any of its respective successors, assigns, legal
representatives, agents and servants (whether or not also indemnified against by
the manufacturer(s) or any other person), in any way relating to or arising out
of this Lease or any document contemplated hereby, or the performance or
enforcement of any of the terms hereof, or in any way relating to or arising out
of the manufacture, purchase, acceptance, rejection, return lease, ownership,
possession, use, condition, operation, sale or other disposition of the
Equipment or any accident in connection therewith (including, without
limitation, latent or other defects, whether or not discoverable); provided,
however, that Lessee shall not be required to indemnify Lessor or its respective
successors, assigns, legal representatives, agents and servants, for loss or
liability in respect of any item of Equipment arising from acts or events which
occur after possession of such item of Equipment has been returned to Lessor or
loss or liability resulting from the willful misconduct or gross negligence of
the party otherwise to be indemnified hereunder. Lessee agrees that Lessor shall
not be liable to Lessee for any liability, claim, loss, damage or expense of any
kind or nature arising in strict liability or caused directly or indirectly by
the inadequacy of the Equipment for any purpose or any deficiency or defect
therein or the use or maintenance thereof or any repairs, servicing or
adjustments thereto or any delay in providing or failure to provide any thereof
or any interruption or loss of service or use thereof or any loss of business.

13.    REMEDIES.

Lessee shall be in default hereunder, and there shall be a breach of this
Agreement, if:

<PAGE>   8

(a)    Lessee fails to pay any installment of rent within twenty (20) days when
       the same becomes due and payable.

(b)    Lessee attempts to remove, sell, transfer, encumber, sublet or part with
       possession of the Equipment or any items thereof, except as expressly
       permitted herein.

(c)    Lessee shall fail to observe or perform any of the other obligations
       required to be observed or performed by Lessee hereunder, and such
       failure shall continue uncured for ten (10) days after written notice
       thereof to Lessee by Lessor.

(d)    Lessee ceases doing business as a going concern, makes an assignment for
       the benefit of creditors, admits in writing its inability to pay its
       debts as they become due, files a voluntary petition in bankruptcy, is
       adjudicated a bankrupt or an insolvent, files a petition seeking for
       itself any reorganization, arrangement, composition, readjustment,
       liquidation, dissolution or similar arrangement under any present or
       future statute, law or regulation, or files an answer admitting the
       material allegations of a petition filed against it in any such
       proceeding, consents to, or acquiesces in the appointment of, a trustee,
       receiver, or liquidator of it or of all or any substantial part of its
       assets or properties, or if it or its shareholders shall take any action
       looking to its dissolution or liquidation.

(e)    Within thirty (30) days after the commencement of any proceedings against
       Lessee seeking reorganization, arrangement, readjustment, liquidation,
       dissolution or similar relief under any present or future statute, law or
       regulation, such proceedings shall not have been dismissed, or if within
       30 days after the appointment without Lessee's consent or acquiescence of
       any trustee, receiver or liquidator of it or of all or any substantial
       part of its assets and properties, such appointment shall not be vacated.

       In the event that Lessee is in default hereunder, then, in any such
       event, Lessor may at its option do any or all of the following: (i) by
       notice to Lessee terminate this Agreement as to all or any Equipment
       Schedules; (ii) whether or not this Agreement is terminated as to all or
       any Equipment Schedules, take possession of any or all of the Equipment
       on any Equipment Schedule wherever situated, and for such purpose, enter
       upon any premises without liability for so doing; (iii) sell, dispose of,
       hold, use or lease any Equipment on any Equipment Schedule as Lessor in
       its sole discretion may decide, without any duty to account to Lessee;
       (iv) by notice to Lessee, declare immediately due and payable all monies
       to be paid by Lessee during the Initial Period or, if the Initial Period
       has then expired, declare immediately due and payable all monies to be
       paid during any term (extended as provided in Paragraph 3 (a) hereof)
       then in effect, and Lessee shall thereupon be obliged to pay such monies
       to Lessor immediately. Lessee shall in any event remain fully liable for
       reasonable damages as provide by law and for all costs and expenses
       incurred by Lessor on account of such default, including all court costs
       and reasonable attorney's fees. In any legal action between Lessor and
       Lessee, Lessee expressly waives its right to trial by jury. The waiver by
       Lessor of any breach of any obligation of Lessee shall not be deemed a
       waiver of such obligation or of any

<PAGE>   9

       subsequent breach of the same or any other obligation. The subsequent
       acceptance of rental payments hereunder by Lessor shall not be deemed a
       waiver of any prior existing breach by Lessee regardless of Lessor's
       knowledge of such prior existing breach at the time of acceptance of such
       rental payments. The rights afforded Lessor under this Paragraph shall
       not be deemed to be exclusive, but shall be in addition to any rights or
       remedies provided by law.

14.    PERFORMANCE OF OBLIGATIONS OF LESSEE BY LESSOR.

If Lessee shall be in default hereunder, Lessor may thereafter, without thereby
waiving any obligation of Lessee or such default make the payment or perform or
comply with the agreement, the nonpayment, nonperformance or noncompliance with
which caused such default, and the amount of such payment and the amount of the
reasonable expenses of Lessor incurred in connection with such payment or the
performance of or compliance with such agreement, as the case may be, shall be
payable by Lessee upon demand.

15.    GENERAL.

(a)    This Agreement shall not be binding upon Lessor unless signed on its
       behalf by a duly authorized officer. This Agreement shall be deemed to
       have been made in the State of New York and shall be governed in all
       respects by the laws of such State.

(b)    This Agreement (including the attached Equipment Schedules and
       Supplements) constitutes the entire Agreement between Lessee and Lessor
       with respect to the Equipment, and no covenant, condition or other term
       or provision may be waived or modified orally.

(c)    All notices hereunder shall be in writing and shall be delivered in
       person or sent by registered or certified mail, postage prepaid, to the

1.LEASE: Subject to the following terms and conditions, Working Capital
Technologies of America ("Lessor") hereby agrees to lease to Lessee the
Hardware, Software and other Equipment ("Property") described on the Lease
Schedule(s) ("Schedule(s)") referencing this Lease Agreement ("Agreement"), and
Lessee agrees to lease the Property from the Lessor. Each Schedule that the
parties may from time to time enter into with respect to this Agreement
incorporates the terms of the Agreement and constitutes a separate lease
agreement and is referred to herein as the "Lease".

2. UNIFORM COMMERCIAL CODE ACKNOWLEDGMENT: Lessee acknowledges that it has
received and approved any written "Supply Contract" covering the Property
purchased from the Supplier for lease and Lessor has informed or advised Lessee,
either previously or by this Lease, of the following: (i) the identity of the
Supplier; (ii) that Lessee may have rights under the Supply Contract; (iii) that
Lessee may contact the Supplier for a description of any such rights. This Lease
is a "Finance Lease". (The terms "Finance Lease", "Supply Contract" and
"Supplier" as used in this Lease have the meanings only as ascribed to them
under Division 10 of the California Uniform Commercial Code and have no effect
on any tax or accounting treatment). This provision survives termination of the
Lease.

3. TERM: This Lease, with respect to any Schedule, shall become effective upon
acceptance by Lessor and the term for any Schedule(s) shall commence on the day
Lessee certifies that the Property has been delivered to and is usable by Lessee
("Commencement Date"). Lessee agrees that its remedies, should it find fault
with any of the Property, shall be and are solely against the
manufacturer/vendor/licensor ("Supplier") and not against Lessor. This Lease
shall give Lessee the right to use the Property at the location(s) delineated on
the Schedule(s). The initial base term of the Lease shall be as indicated on the
respective Schedule(s) and shall be calculated from the first day of the
calendar quarter following the Commencement Date ("Base Lease Term"). A calendar
quarter means a three-month period commencing on January 1, April 1, July 1, and
October 1 of any calendar year. The Base Lease Term shall be extended for an
additional one-year period (the "extended Base Lease Term") at the rate
delineated on the respective Schedule(s) unless Lessee provides to Lessor
written notice of Lessee's election not to extend the Base Lease Term at least
one hundred eighty (180) days prior to the expiration of the initial Base Lease
Term. Notwithstanding the provisions of Section 20 below, such written notice
may be delivered to Lessor by hand or by certified mail and shall not be
effective unless it is actually received by Lessor at least one hundred (180)
days prior to the expiration of the initial Base Lease Term. At the expiration
of the initial Base Lease Term (or, if extended, at the expiration of the
extended Base Lease Term), Lessee shall do one of the following: (i) purchase
all, but not less than all, of the Property for its then Fair Market Value
("FMV"), plus applicable sales tax; (ii) promptly return all, but not less than
all, of the Property and lease replacement property from Lessor which has a cost
equal or to greater than the original cost of the Property; or (iii) extend the
Schedule for a period of one additional year at the rental rate delineated on
the respective Schedule. With respect to Option (i), FMV is the price a willing
buyer (who is neither a used property dealer or reseller) would pay for the
Property

in an arm's length transaction to a willing seller under no compulsion to sell.
Such FMV shall be determined on the basis that: (a) the Property is assumed to
be in the condition in which it is to be maintained under the Lease and is in
complete compliance with all other terms of the Lease; (b) the Property is
assumed to be installed and/or in full service and is valued on an installed
basis; and (c) the cost of removal of the Property from its present location is
not deducted from the valuation. If Lessee elects to purchase the Property and
the parties are not able to agree on FMV at least 60 days prior to the
expiration of the applicable term, Lessor shall appoint an independent appraiser
(reasonably acceptable to Lessee) who shall determine FMV, and the parties
acknowledge and agree that such determination shall be final, binding and
conclusive with respect to the parties' agreed upon purchase price. Lessee shall
be responsible for the cost of the appraisal. With respect to Option (ii),
Lessee and Lessor shall each have absolute discretion regarding their agreement
or lack of agreement to the terms of a lease for replacement property. If Lessee
has not elected Option (i) or (ii) by the end of the initial Base Lease Term or,
if extended, the extended Base Lease Term, then Option (iii) shall prevail.
Thereafter, this Lease will continue subject to termination by either Lessee or
Lessor at the end of any month, provided at least ninety days' prior notice is
delivered to the other party. Each Schedule shall be deemed to incorporate
therein these specific terms and conditions and shall have an independent
initial Base Lease Term and extension period(s).

4. RENT: The monthly rent payable with respect to any Schedule(s) shall be the
amount shown with respect to such Schedule(s). Lessee shall pay to the Lessor
the monthly rent for each Schedule, in advance, for each month or any part
thereof that this Lease, with respect to said Schedule(s), is in effect. The
first such payment shall be made on the first day of the calendar quarter
following the Commencement Date. A prorata portion of the monthly rental charges
based on a daily rental of one-thirtieth (1/30th) of the monthly rental
calculated from the Commencement Date to the end of the calendar quarter, shall
be due and payable at the Commencement Date. If rent or any other amount is not
paid within ten days of its due date, Lessee agrees to pay a late charge equal
to five percent (5%) of the unpaid amount. Each month thereafter, past due
amounts remaining unpaid hereunder shall bear interest at the lesser of one and
one-half percent (1 1/2%) per month, compounded monthly or the maximum rate
allowed by law. All rent shall be paid at the place of business if Lessor shown
above or such other place as Lessor may designate by written notice to Lessee.
Except as otherwise provided in this Lease, Lessee's obligation to pay rent
shall be absolute and unconditional under all circumstances, notwithstanding:
(i) any setoff, counterclaim, recoupment, defense or other right which Lessee
may have against Lessor for any reason whatsoever; or (ii) any defect in the
title, right to use, condition, operation, fitness for use, damage or
destruction of or to the Property or any interruptions or cessations in use or
possession thereof for any reason whatsoever. Lessee hereby waives, to the
extent permitted by law, the following rights and remedies which may be
conferred upon Lessee by law: (a) the right to cancel or terminate this Lease
except in accordance with the express terms hereof, (b) right to revoke
acceptance of the Property, (c) right to recover damages from Lessor for any
breach of warranty and (d) right to recover any consequential damages
whatsoever.

5. ADDITIONS AND MODIFICATIONS: All additions and modifications to the Property
become an integral part of the Property and are owned by Lessor. Software, as
described on any Schedule(s), includes all updates, revisions, upgrades, new
versions, enhancements, modifications, derivative works, maintenance fixes,
translations, adaptations, and copies of the foregoing or of the original
version of the Software whether obtained from the Supplier, or from any source
whatsoever, and references in this Lease to Software will be interpreted as
references to any and all of the foregoing. All additions and modifications to
the Property must be free and clear of any liens or rights of other parties.

6. NO WARRANTIES: Lessor not being the Supplier, manufacturer, developer,
publisher, distributor, or licensor of the Property, MAKES NO WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, NOR SHALL IT BE DEEMED TO HAVE MADE ANY
SUCH WARRANTIES OR REPRESENTATIONS AS TO THE MERCHANTABILITY, COMPATIBILITY,
FITNESS, DESIGN, CONDITIONS, QUALITY OR CAPACITY OF THE LEASED PROPERTY, OR ANY
OTHER REPRESENTATION OR WARRANTY WHATSOEVER WITH RESPECT TO THE PROPERTY. LESSEE
REPRESENTS THAT ALL OF THE PROPERTY ARE OF A SIZE, DESIGN, AND CAPACITY SELECTED
BY IT, AND THAT IT IS SATISFIED THAT THE SAME IS SUITABLE FOR LESSEE'S PURPOSES.
Lessor assigns to Lessee during the term of the Lease any warranty rights it may
have received from the Supplier as a result of Lessor's purchase of the
Property. If Lessee has any claims regarding the Property or any other matter
arising from Lessee's relationship with the Supplier, Lessee must make them
against the Supplier. This provision survives termination of the Lease.

7. MAINTENANCE: Lessee at its own expense, will provide a suitable place for the
operation of the Property, and keep in force for the term of the Lease the best
standard Supplier's maintenance agreement(s) which will cause the Supplier(s) to
make all the necessary repairs, adjustments, and replacements in accordance with
such maintenance agreement(s) and entitle Lessee (through Lessor, if necessary)
to obtain available enhancements, updates, upgrades and changes.

8. RISK OF LOSS: During the period the Property is in transit, is in the
possession of Lessee, and until the Property is returned to Lessor, Lessee shall
assume all responsibility for loss or damage and shall hold Lessor harmless
against the same. In the event that, during the term of the Lease or until the
Property shall have been returned, if any of the Property shall be confiscated,
taken, requisitioned, lost, stolen, destroyed or irreparably damaged for any
cause whatsoever (such occurrences being hereinafter called "Casualty
Occurrences"), Lessee shall immediately and fully inform Lessor. In the case of
Software, the erasure, inoperability or other incapacity of the Software
triggered by a preprogrammed termination or limiting design or routine embedded
in the Software shall also be deemed a "Casualty Occurrence". Following a
Casualty Occurrence, on the next succeeding rent payment date, Lessee shall pay
to Lessor, in addition to all past due rentals and other amounts then late and
outstanding, an amount equal to the Casualty Value as determined by the attached
Casualty Schedule as of the date of the Casualty Occurrence. Upon the making of
such payment by Lessee, the rental for such Schedule(s) shall cease to accrue as
of the date of such payment and the term of the Lease as to such Schedule(s)
shall terminate, Insurance proceeds received by Lessor as the result of a
Casualty Occurrence with respect to any Schedule(s) shall be applied in
reduction of Lessee's obligation to pay the Casualty Value. The Casualty Value
as of any rent payment date (or as of any other date on which Casualty Value is
payable shall be an amount equal to that percentage of the Purchase Price or
License Fee as is set forth in the Casualty Schedule attached hereto, opposite
the number of such rent payment date or such other date. The Purchase Price or
License Fee of any Property shall be the

                                       2
<PAGE>   3

total cost paid by Lessor with respect to the Property.

9. INDEMNIFICATIONS AND INSURANCE: Lessee assumes liability for, and agrees at
its own expense to indemnify and defend Lessor, its employees, officers,
directors and assigns, from and against any and all claims, liabilities, losses,
damages, and expenses (including legal expenses) of every kind or nature
(including, without limitation, claims based upon strict liability) arising out
of the use, condition (including latent and other defects, whether or not
discoverable by Lessee or Lessor), operation or ownership of any items of
Property (including, without limitation, any claim for patent, trademark or
copyright infringement) or for any interruptions of service, loss of business,
or consequential damages. These indemnities and assumptions survive termination
of this Lease. Lessee, at its expense, shall procure and maintain in full force
and effect such public liability (including, without limitation, contractual
liability insurance), property damage liability, fire with extended coverage,
theft, and other insurance in such form and amounts and with such companies as
shall be satisfactory to Lessor. Lessor shall be named as an additional insured
and loss payee on all policies which shall provide that no cancellation thereof
shall be effective without thirty (30) days' prior written notice to Lessor and
shall not be invalidated as to Lessor by any act, omission or neglect of Lessee.

10. TAXES: Lessee shall pay directly, all License fees, registration fees,
assessments and taxes which may now or hereafter be imposed upon the ownership,
sale (if authorized), possession or use of the Property, excepting only those
based on Lessor's income, and shall keep the Property free and clear of all
levies, liens or encumbrances arising therefrom. While Lessee is responsible for
payment of all personal property taxes, Lessor will file all personal property
tax returns. Lessor shall not be responsible for contesting any valuation of or
tax imposed on the Property, but may do so strictly as an accommodation to
Lessee and shall not be liable or accountable to Lessee therefor.

11. OWNERSHIP: Lessor at all times retains ownership, title and/or control over
Lessee's right to use the Property in accordance with the terms of the Lease. To
the extent Software subject to this Lease may also be the subject of a license
agreement between the Supplier and Lessee, Lessee acknowledges that the License
to use the Software is being provided to Lessee solely because of payments made
by Lessor to the Supplier and, accordingly, Lessee agrees that Lessor has an
interest in the license. Lessee agrees that if it or any of its affiliates
receives anything of value from the Supplier (including without limitation, a
trade-in, substitution, discount or upgrade allowance) other than Lessee's
rights to use the Software reflected on the Schedule for the term of this Lease,
Lessee will advise Lessor and pay to Lessor an amount equal to such additional
value obtained by Lessee. Lessee agrees that it will not surrender, transfer or
modify the license agreement without first obtaining the written consent of
Lessor. Lessee will at all times protect and defend, at its own cost and
expense, the title and/or License rights of Lessor from and against all claims,
liens and legal processes and keep all Property free and clear from all such
claims, liens and processes. The Property is and shall remain personal property
of Lessor.

12. EFFECTS OF TERMINATION OR EXPIRATION OF LEASE TERM: In the event Lessee
elects to return the Property to Lessor in accordance with the express terms of
the Lease, Lessee will discontinue its use of the Property, pay to Lessor an
inspection, refurbishment and restocking fee equal to five percent (5%) of the
Lessor's original cost of the Property, and immediately, at its own expense,
ship the Property, with all manuals, cables, cartons and packing materials as
originally furnished by Supplier, to a location within the United States in
accordance with the Property return instructions provided by Lessor. In the case
of Software, Lessee will destroy all intangible Software items, and deliver to
Lessor all tangible items constituting Software. At Lessor's request, Lessee
will also certify in a written form acceptable to Lessor that: (i) all the
tangible Software has been delivered to Lessor; (ii) all intangible records have
been destroyed; (iii) Lessee has not retained the Software in any form; (iv)
Lessee will not use the Software after termination and (v) Lessee has not
received from Supplier(s) anything of value relating to or in exchange for
Lessee's use, rental or possession of the Software during the term of the Lease
(including a trade-in, substitution or upgrade allowance). Until Lessee has
complied with all of the requirements of this Section, rent payment obligations
will continue from month to month at the rental rate delineated on the Schedule.
TERMINATION OF ANY LEASE TERM (OR TERMINATION OF THE LICENSE SHALL NOT ABSOLVE
USER FROM PAYMENT OF ACCRUED PERIODIC PAYMENTS OR FROM COMPLIANCE WITH THE USE
AND DISCLOSURE RESTRICTIONS OF THIS AGREEMENT, OR FROM ITS OBLIGATIONS TO
INDEMNIFY LESSOR.

13. PERFORMANCE OF LESSEE'S OBLIGATIONS BY LESSOR: If Lessee fails duly and
promptly to perform any of its obligations under this Lease, Lessor may, at its
option, immediately or at any time thereafter perform the same for the account
of Lessee without thereby waiving Lessee's default, and any amount paid, expense
(including reasonable attorney's fees), penalty or other liability incurred by
Lessor in such performance shall be payable by Lessee to Lessor upon demand,
with interest thereon at the rate set forth in Paragraph 3, above.

14. INSPECTION: In addition to its rights of entry and inspection stated
elsewhere in this Lease, Lessor may from time to time during reasonable business
hours enter upon any premises where any of the Property may be located for the
purpose of confirming the existence, condition, and proper maintenance of the
Property.

15. DEFAULT: An Event of Default shall occur if: (a) Lessee fails to pay within
ten (10) days after the due date, any installment of rent; (b) Lessee fails to
perform or observe any covenant, condition, or obligation to be performed or
observed by it under this Lease and such failure continues uncured for fifteen
(15) days after written notice thereof to Lessee by Lessor; (c) Lessee makes an
assignment for the benefit of its creditors, files any petition or takes any
action under any bankruptcy, reorganization or insolvency laws; (d) an
involuntary petition is filed under any bankruptcy statute against Lessee or any
receiver, trustee or custodian is appointed to take possession of Lessee's
properties, unless such petition or appointment is set aside or withdrawn within
sixty days of said filing or appointment; (e) Lessee attempts to or does remove,
transfer, sell, sublicense, encumber, part with possession, or sublet any of the
Property; (f) Lessee attempts to assign or transfer this Lease or its interest
under the Lease or moves the Property from the location(s) set forth on the
Schedule without Lessor's prior written consent; or (g) Lessee undergoes a sale,
buyout, change in control, or change in ownership of any type, form or manner
which, as judged solely by Lessor, results in a material deterioration in
Lessee's credit worthiness.

16. REMEDIES: If an Event of Default shall occur and be continuing, Lessor may
exercise at its sole option, but not specifically limited thereto, any one or
more of the following remedies: (a) terminate this Lease and Lessee's rights
hereunder, (b) proceed, by

                                       3
<PAGE>   4
appropriate court action or actions either at law or in equity, to enforce
performance by Lessee of the applicable covenants of this Lease or to recover
damages for the breach thereof, (c) by notice in writing to Lessee, recover all
amounts due on or before the date Lessor declared this Lease to be in default,
plus, as liquidated damages for loss of a bargain and not as a penalty,
accelerate, and declare to be immediately due and payable, all rentals and other
sums payable hereunder, without any presentment, demand, protest or further
notice (all of which hereby are expressly waived by Lessee), whereupon the same
shall be and become immediately due and payable, and (d) take immediate
possession of the Property, or any part thereof, from Lessee free from all
claims by Lessee. In the case of Software, it is acknowledged and agreed that
the unauthorized use, disclosure, or transfer of the Software could cause Lessor
incalculable, irreparable, and serious harm. Therefore, if Lessee is found to be
using (in whatever manner) any portion of the Software after the applicable
Lease Term or if Licensor terminates a License or Lessee's right to use the
Software thereunder for an alleged breach of the License's use, disclosure, or
transfer restrictions, then liquidated damages shall be payable immediately to
Lessor in an amount equal to two (2) times the amount paid by Lessor with
respect to the Software. The exercise of any of the foregoing remedies by Lessor
shall not constitute a termination of this Lease unless Lessor so notifies
Lessee in writing. In the event Lessor repossesses the Hardware, Lessor may (A)
lease the Hardware or any portion thereof, in such a manner, for such time and
upon such terms as Lessor may determine, or (B) sell the Hardware or any portion
thereof, at one or more public or private sales, in such manner, and at such
times and upon such terms as Lessor may determine. In the event that Lessor
leases the Hardware, any rentals received by Lessor for the remaining lease term
(the period ending on the date when the initial Base Lease Term for the Hardware
would have expired) shall be applied to the payment of: (i) all costs and
expenses (including reasonable attorney's fees) incurred by Lessor in retaking
possession of, and removing, storing, repairing, refurbishing and leasing such
Hardware, and (ii) the rentals for the remainder of the initial term and all
other sums then remaining unpaid under this lease. The remaining balance of such
rentals, if any, shall be applied to reimburse Lessee for any sums previously
paid by Lessee as liquidated damages. All rentals received by Lessor for the
period commencing after the remaining Initial Base Lease Term shall be retained
by Lessor. Lessee shall remain liable to Lessor to the extent that the aggregate
amount of the sums referred to in clauses (i) and (ii) above shall exceed the
aggregate rentals received by Lessor under such leases for the respective
remaining lease term applicable to the Hardware covered by such leases. In the
event that Lessor shall sell or otherwise dispose of (other than pursuant to a
lease) the Hardware, the proceeds thereof shall be applied to the sum of (1) all
costs and expenses (including reasonable attorney's fees) incurred by Lessor in
retaking possession of, and removing, storing, repairing, refurbishing and
selling or otherwise disposing of such Hardware, (2) the rentals accrued under
this Lease, but unpaid up to the time of such sale or other disposition, (3) any
and all other sums (other than rentals) then owing to Lessor by Lessee
hereunder, and (4) the Casualty Value of such Hardware determined as of the date
of such sale or other disposition in accordance with the Casualty Schedule,
attached hereto. The remaining balance of such proceeds, if any, shall be
applied first to reimburse Lessee for any sums previously paid by Lessee as
liquidated damages, and any remaining amounts shall be retained by Lessor.
Lessee shall remain liable to Lessor to the extent that the aggregate amount of
the sums referred to in clauses (1) through (4) above shall exceed the aggregate
proceeds received by Lessor in connection with the sale or disposition of the
Property. Lessor's remedies, as discussed in this Agreement, including but not
limited to remedies discussed in this paragraph shall not be deemed exclusive.
Waiver of any defaults or breach of this Lease shall not be construed as a
waiver of subsequent or continuing defaults or breaches.

  17 ATTORNEY'S FEES AND VENUE OF LITIGATION: THE PARTIES AGREE THAT ALL
DISPUTES, WHETHER BASED IN TORT OR CONTRACT, RELATING TO OR ARISING OUT OF THIS
LEASE WILL BE SUBMITTED TO THE ORANGE COUNTY, CALIFORNIA OFFICE OF ENDISPUTE,

CONDUCTED BY A RETIRED JUDGE OR JUSTICE FROM THE PANEL OF JAMS, APPOINTED
PURSUANT TO A GENERAL REFERENCE UNDER CALIFORNIA CODE OR CIVIL PROCEDURE SECTION
838(1) OR ANY AMENDMENT, ADDITION OR SUCCESSOR SECTION THERETO) UNLESS LESSOR OR
ITS ASSIGNEE SELECTS AN ALTERNATIVE FORUM. IF THE PARTIES ARE UNABLE TO AGREE ON
A MEMBER OF THE JAMS PANEL, THEN ONE SHALL BE APPOINTED BY THE PRESIDING JUDGE
OF THE CALIFORNIA SUPERIOR COURT FOR THE COUNTY OF ORANGE, IN THE EVENT THAT

DISPUTES ARISING UNDER THIS LEASE FOR ANY BREACH WILL BE FILED AND CONDUCTED IN
THE CALIFORNIA SUPERIOR COURT FOR THE COUNTY OF ORANGE, UNLESS LESSOR OR ITS
ASSIGNEE SELECTS AN ALTERNATIVE FORUM, LESSEE AGREES TO SUBMIT TO THE PERSONAL
JURISDICTION OF THE CALIFORNIA SUPERIOR COURT FOR THE COUNTY OF ORANGE. LESSEE
AND LESSOR WAIVE THEIR RIGHTS TO A JUST TRIAL IN ANY ACTION ARISING OUT OF OR
RELATING TO THIS LEASE. If any party to this Lease brings any action to enforce
any of the terms, or to recover for any breach, then the prevailing party is
entitled to recover reasonable attorneys' fees, and cost, including all
JAMS-related costs and costs of collection, from the other party.

  18 TRANSPORTATION; INSTALLATION/DEINSTALLATION: All transportation, rigging
and damage charges on delivery or redelivery of the Property to and from Lessee

meanings set forth in then Lease, unless specifically modified. This Addendum
is to be construed as supplemental to, and part of, the Lease.

Throughout the term of the Lease, as security for Lessee's obligations
hereunder, Lessee agrees to maintain at its sole cost and expense an
unconditional and irrevocable stand by letter of credit ("Letter of Credit") in
the amount of Two Million Seven Hundred Ninety-Two Thousand Seven Hundred
Ninety-One dollars and 43/100 U.S. Dollars ($2,792,791.43), in form, substance,
and issued by a bank satisfactory to WCT. Such Letter of Credit will be
considered for full or partial release at WCT's absolute and sole discretion,
not less than biannually. Lessee agrees to obligate the issuer to notify WCT in
writing at least ninety (90) days in advance of any date of expiration of such
Letter of Credit that such Letter of Credit has not been renewed. In addition
to the provisions of Section 9 of the Agreement, it shall be an Event of
Default hereunder if WCT does not receive a satisfactory replacement Letter of
Credit, at least sixty (60) days in advance of any expiration or cancellation
of any Letter of Credit issued pursuant to this Lease. If there is any Event of
Default under the Lease, WCT may draw all or part of the amount available under
such Letter of Credit, and may pursue any or all of its other remedies
available. WCT may draw upon the Letter of Credit to obtain payment of any
amounts due and unpaid under the Lease.

In all other respects, the terms and conditions of the Lease, as originally set
forth, shall remain in full force and effect. The Lease sets forth the entire
and final understanding between the parties with respect hereto. The terms of
this Addendum have been negotiated and jointly drafted by WCT and Lessee and,
therefore, the language of the Addendum shalt not be construed in favor or
against either party. The undersigned represent that they have the authority to
enter into this Lease, and that the same shall be legally binding and
enforceable on the respective principals.

IN WITNESS WHEREOF, the parties hereto, by their authorized signatories, have
executed this Addendum "B" at the date set forth below their respective
signatures.
