         MASTER LEASE AGREEMENT

         Master Lease # SL2890

Lessor agrees to lease to Lessee and Lessee agrees to lease from Lessor, subject
to the following terms of this Master Lease Agreement ('Master Lease') and any
Lease Schedule ('Schedule'), collectively referred to as the Lease ('Lease'),
the personal property described in any Schedule together with all attachments,
replacements, parts, substitutions, additions, upgrades, accessories, software
licenses and operating manuals (the 'Product'). Each Schedule shall constitute a
separate, distinct, and independent Lease and contractual obligation of Lessee.

1.       Commencement Date And Term

The initial lease term ('Initial Term') and Lessee's rental obligations shall
begin on the Commencement Date and continue for the number of Rental Periods
specified in the Lease as set forth in Section 2 below and shall renew
automatically thereafter until terminated by either party upon not less them
ninety (90) days' prior written notice. The Commencement Date with respect to
each item of Product shall be the 16th day after date of shipment to Lessee.

2.       Rent and Rental Period

All rental payments and any other amounts payable under a Lease are collectively
referred to as 'Rent'. The Rental Period shall mean the rental payment period of
either calendar months, quarters, or as otherwise specified in each Schedule.
Rent for the specified Rental Period is due and payable in advance, to the
address specified in Lessor's invoice, on the first day of each Rental Period
during the Initial Term and any extension (collectively, the 'Lease Term'),
provided, however, that Rent for the period of time (if any) from the
Commencement Date to the first day of the first Rental Period shall begin to
accrue on the Commencement Date. If any Rent is not paid when due, Lessee will
pay a service fee equal to five percent (5%) of the overdue amount plus interest
at the rate of one and one half percent (1.5%) per month or the maximum legal
interest rate, whichever is less.

3.       Net Lease, Taxes and Fees

Each Schedule shall constitute a net lease and payment of Rent shall be absolute
and unconditional, and shall not be subject to any abatement, reduction, setoff,
defense, counterclaim, interruption, deferment or recoupment for any reason
whatsoever. Lessee agrees to pay Lessor when due shipping charges, fees,
assessments and all taxes (municipal, state and federal) imposed upon a Lease or
the Product or its ownership, leasing, renting, possession or use except for
taxes based on Lessor's income.

4.       Title

Product shall always remain personal property. Lessee shall have no right or
interest in the Product except as provided in this Master Lease and the
applicable Schedule and shall hold the Product subject and subordinate to the
rights of Lessor. Lessee agrees to execute UCC financing statements as and when
requested by Lessor and hereby appoints Lessor as its attorney-in-fact to
execute such financing statements. Lessor may file a photocopy of any Lease as a
financing statement.

Lessee will, at its expense, keep the Product free and clear from any liens or
encumbrances of any kind (except any caused by Lessor) and will indemnify and
hold Lessor harmless from and against any loss or expense caused by Lessee's
failure to do so. Lessee shall give Lessor immediate written notice of any
attachment or judicial process affecting the Product or Lessor's ownership. If
requested, Lessee will label the Product as the property of Lessor and shall
allow, subject to Lessee's reasonable security requirements, the inspection of
the Product during regular business hours.

5.       Use, Maintenance And Repair

Lessee, at its own expense, shall keep the Product in good repair, appearance
and condition, other than normal wear and tear and shall obtain and keep in
effect throughout the term of the Schedule a hardware and software maintenance
agreement with the manufacturer or other party acceptable to Lessor. All parts
furnished in connection with such repair and maintenance shall be
manufacturer-authorized parts and shall immediately become components of the
Product and the property of Lessor. Lessee shall use the Product in compliance
with the manufacturer's or supplier's suggested guidelines.

6.       Delivery And Return of Product

Lessee assumes the full expense of transportation, insurance, and installation
to Lessee's site. Upon termination of each Schedule, Lessee will provide
operating condition and is eligible for continued maintenance and that the
operating system is at the then current level, unless under a Sun service
contract during the Lease Term. Lessee, at its expense, shall deinstall, pack
and ship the Product to a U.S. location identified by Lessor. Lessee shall
remain obligated to pay Rent on the Product until the Product and certification
are received by Lessor.

7.       Assignment And Relocation

Lessee may sublease or assign its rights under this agreement with Lessor's
prior written consent, which consent shall not be unreasonably withheld,
subject, however, to any terms and conditions which Lessor may require. No
permitted assignment or sublease shall relieve Lessee of any of its obligations
hereunder.

Lessee acknowledges Lessor may sell and/or assign its interest or grant a
security interest in each Lease and/or the Product to an assignee ('Lessor's
Assignee'), so long as Lessee is not in default hereunder. Lessor or Lessor's
Assignee shall not interfere with Lessee's right of quiet enjoyment and use of
the Product. Upon the assignment of each Lease, Lessor's Assignee shall have any
and all discretions, rights and remedies of Lessor, and all references to Lessor
shall mean Lessor's Assignee. In no event shall any assignee of Lessor be
obligated to perform any duty, covenant or condition under this Lease, and
Lessee agrees it shall pay such assignee without any defense, rights of set-off
or counterclaims and shall not hold or attempt to hold such assignee liable for
any of Lessor's obligations hereunder.

Lessee, at its expense, may relocate Product (after packing it for shipment in
accordance with the manufacturer's instructions) to a different address with
thirty (30) days' prior written notice to Lessor. The Product shall at all times
be used solely within the United States.

8.       Upgrades And Additions

Lessee may affix or install any accessory, addition, upgrade, equipment or
device on the Product ('Additions') provided that such Additions (i) can be
removed without causing material damage to the Product, (ii) do not reduce the
value of the Product and (iii) are obtained from or approved by Sun Microsystems
Computer Corporation and are not subject to the interest of any third party
other than Lessor. Any other Additions may not be installed without Lessor's
prior written consent. At the end of the Schedule Term, Lessee shall remove any
Additions which (i) were not leased by Lessor and (ii) are readily removable
without causing material damage or impairment of the intended function, use, or
value of the Product and restore the Product to its original configuration. Any
Additions which are not so removable will become the Lessor's property (lien
free).

9.       Lease End Options

Upon written notice given at least ninety (90) days prior to expiration of the
Lease Term, and provided Lessee is not in default under any Schedule, Lessee may
(i) exercise any purchase option set forth in the Schedule, or (ii) renew the
Schedule for a minimum extension period of twelve (12) months, or (iii) return
the Product to Lessor at the expiration date of the Schedule pursuant to Section
6 above.

10.      Insurance, Loss or Damage

Effective upon shipment of Product to Lessee and until Product is received by
Lessor, Lessee shall provide at its expense (i) insurance against the loss or
theft or damage to the Product for the full replacement value, and (ii)
insurance against public liability and property damage. Lessee shall provide a
certificate of insurance that such coverage is in effect, upon request by
Lessor, naming Lessor as loss payee and/or additional insured as may be
required.

Lessee shall bear the entire risk of loss, theft, destruction of or damage to
any item of Product. No loss or damage shall relieve Lessee of the obligation to
pay Rent or any other obligation under the Schedule. In the event of loss or
damage, Lessee shall promptly notify Lessor and shall, at Lessor's option, (i)
place the Product in good condition and repair, or (ii) replace the Product with
lien-free Product of the same model, type and configuration in which case the
relevant Schedule shall continue in full force and effect and clear title in
such Product shall automatically vest in Lessor, or (iii) pay Lessor the present
value of remaining Rent plus the buyout purchase option price provided for in
the applicable Schedule.
