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 than
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 to Lessor  interest at the rate of one and one half percent (1.5%) per month
(i.e. 18% per annum) on the amount of unpaid Rent.

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,
set-off, defense,  counterclaim,  interruption,  deferment or recoupment for any
reason whatsoever.  Lessee agrees to pay Lessor when due shipping charges, fees,
and  assessments.  Lessee will pay when due or  reimburse  Lessor for all taxes,
fees or any other charges  (together with any related  interest or penalties not
arising from the negligence of Lessor) accrued for or arising during the term of
each  Schedule  against  Lessor.  Lessee  or the  Product  by  any  governmental
authority (except only Federal, Provincial and local taxes on the capital or the

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,  and Lessee  shall not  represent  to any third party that the
Product is the property of Lessee.  When necessary under  applicable law, Lessee

name  security  registration  statements,   affidavits,   or  other  instruments
reasonably  required to evidence  and protect the  interest of the Lessor or the
Lessor's  Assignee (as defined in Section 7 of this Master Lease) in the Product
and to insert serial numbers in Schedules as appropriate.

Lessee will,  at its expense,  keep the Product free and clear from any security
interests,  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.  Lessee will label the Product as the property of Lessor, which label
shall provide that no party shall tamper with, obstruct,  interfere with, remove
or alter the Product in which such label is affixed. Lessee shall allow, subject
to Lessee's  reasonable  security  requirements,  the  inspection of the Product
during regular business hours.

5.       Use, Maintenance and Repair

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 guidelines.

6.       Delivery and Return Product
Lessee assumes the full expense of transportation,  insurance,  and installation
to Lessee's site. Upon termination of each Schedule,  Lessee will provide Lessor
a letter from the manufacturer  certifying that the Product is in good operating
condition  and is eligible  for  continued  maintenance  and that the  operating
system is at then current level,  unless under a Sun Microsystems of Canada Inc.
service contract during the Lease Term. Lessee, at its expense, shall deinstall,
pack and ship the Product to a Canadian  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 Master Lease and a Schedule
with Lessor's prior written  consent,  subject 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

                                       -2-



hereunder  Lessor and 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 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.  Notwithstanding  any such  assignment,
Lessor  shall  remain  liable  to  Lessee  for the  performance  of all  duties,
covenants and conditions  hereunder,  and in no event shall Lessor's Assignee be
obligated to perform any duty, covenant or condition under this Lease and Lessee
agrees it shall pay Lessor's Assignee without any defense,  rights of set-off or
counterclaims and shall not hold or attempt to hold Lessor's 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  Canada and Lessee  hereby  covenants  not to remove any
Products, of any part thereof, from such jurisdiction.

8.       Upgrade and Additions
Lessee may affix or install  any  accessory,  addition,  upgrade,  equipment  or
device on the Product  ("Additions")  provided that such  Additions are obtained
from or  approved  in writing by Sun  Microsystems  of Canada  Inc.  and are not
subject to the interest of any third party other than Lessor.  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  service given at least ninety (90) days prior to expiration of the
Lease Term, provided Lessee is not in default under any Schedule. Lessee may (i)
exercise  any  purchase  option  set forth on 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 returned to
Lessor in  accordance  with each Lease,  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 co-loss  payee or sole loss
payee and/or named 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

                                       -3-



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  (discounted at six (6%) percent per
annum, compounded monthly) plus the buyout purchase option price provided for in
the applicable Schedule.

11.      Selection, Warranties and Limitation of Liability
Lessee  acknowledges that it has selected the Product and disclaims any reliance
upon  statements  made by Lessor.  Lessee  acknowledges  and agrees that use and
possession  of the Product by Lessee shall be subject to and  controlled  by the
terms of any manufacturer's or, if appropriate,  supplier's warranty, and Lessee
agrees to look solely to the  manufacturer  or, if  appropriate,  supplier  with
respect to all  mechanical,  service and other claims,  and the right to enforce
all warranties made by said  manufacturer  are hereby assigned to Lessee for the
term of the Schedule.

leasing, maintenance, delivery or return of any item of Product.

13.      Default and Remedies
Lessee  shall be in  fundamental  breach of any Lease if (i) Lessee fails to pay
Rent within ten (10) days of due date;  (ii) Lessee  fails to perform or observe
or breaches any covenant or condition or any  representation or warranty in such
Lease, and such failure or breach continues  unremedied for a period of ten (10)

permitted in the Lease,  attempts to move, sell, transfer,  encumber,  or sublet
without  consent any item of Product leased under such Lease;  (iv) Lessee files
or has filed against it a petition in bankruptcy or


                                       -4-

consents  to the  appointment  of a  trustee  or  receiver  or  either  shall be
appointed for Lessee or for a substantial part of its property; or (v) Lessee or
any  guarantor  of Lessee  is  declared  legally  deceased  or if  Lessee  shall
terminate  its  existence  by  amalgamation,  winding up its  business,  sale of
substantially all of its assets or otherwise.

Upon  any  such  breach,  Lessor  may,  at its  option,  take one or more of the
following actions: (i) with notice and demand declare all sums due and to become
due under the Schedule  immediately due and payable,  and in so doing accelerate

default,  or the exercise of Lessor's remedies,  and expenses resulting from any
default, or the exercise of Lessor's remedies, including placing such Product in
the  condition  required by Paragraph 8 hereof.  Each remedy shall be cumulative
and in addition to any other remedy  otherwise  available to Lessor at law or in
equity. Any waiver of default by Lessor must be in writing and no such waiver or
any default shall  constitute a waiver of any of Lessor's other rights or future
defaults.

relates to this Master  Lease,  as  amended,  modified  or  supplemented  or any
security  collateral hereto,  Lessee hereby waives the benefit of all provisions

right to demand  security for costs in the event of  litigation.  If this Master
