                                 BUILDING LEASE

         THIS LEASE is made as of the 29th day of May, 1990, by and between
Michael J. Pollastro, Gary T. Pollastro, and John and Carmen Pollastro, husband
and wife, Tenants in Common, whose address is c/o Michael Pollastro, 4213
Lakeridge Drive East, Sumner, Washington 98390, hereinafter referred to as
"Lessor", and AUTOMATED REGISTER SYSTEMS, INC., a Washington corporation,
hereinafter referred to as "Lessee." 

         1.       DESCRIPTION. Lessor, in consideration of the agreements 
contained in this Lease, does hereby lease to Lessee, upon the terms and
conditions hereinafter set forth, that certain building commonly known as the
Automated Retail Systems Building and the real property (the "Property") upon
which it is situated in the City of Seattle, State of Washington (collectively,
the "Premises"), legally described as follows: 

         Lots 17, 18, 19, 20, 21 and 22, Block 26, Hill Tract Addition to the
         City of Seattle, Supplemental Plat, according to the plat recorded in
         Volume II of Plats, Page 51, in King County, Washington,

         2.       TERM.  The term of this Lease shall be for a period of ten 
(10) years, commencing upon the later of October 1, 1990, or Lessor's receipt of
a certificate of occupancy for the Building, and ending at the expiration of the
one hundred twentieth (120th) month following the commencement date. 

         3.       RENT.   During the first three years of the lease term, 
Lessee covenants and agrees to pay Lessor rent each month in advance on the 
first day of each calendar month in the sum of


                                      - 1 -
<PAGE>   2
Seven Thousand and no/100's Dollars ($7,000.00). Rent for any fractional
calendar month, at the beginning or end of the term, shall be the pro rated
portion of the rent. Rent for each one-year period following the first three
years of the lease term will be determined by applying the annual Consumer Price
Index ("CPI") percentage increase, if any, for the one-year period ending
January first (lst) of the year of increase and adding that amount to the then
current rent in order to establish the rent for the following year. Such rental
as established will be paid in equal monthly installments commencing on November
first (1st), and payable on the first day of each month thereafter. The annual
CPI percentage change will be determined by the report from the United States
Department of Labor, Bureau of Statistics, for the Seattle-Everett Metropolitan
Area for all Urban Consumers (calculated on the Base Period: 1967=100). In the
event the Seattle-Everett, Washington Metropolitan Area CPI for all Urban
Consumers presently published by the United States Department of Labor, Bureau
of Labor Statistics, is discontinued, then the parties shall follow, for the
purpose of determining the rent hereunder, any official CPI, whether so named or
designated or not, issued by any authorized agency of the United States which is
designed to supplant or take the place of the presently issued CPI. In no event
shall the minimum monthly or rent be less than the amount previously stated in
this Paragraph 3.

         4.       CONSIDERATION.  As consideration for the execution of this 
Lease, Lessee has paid to Lessor the first month's rent in

                                      - 2 -

Premises for a business office only and for no other purpose.

         6.       RULES AND REGULATIONS. Lessee and their agents, employees, 
servants or those claiming under Lessee will at all times observe, perform and
abide by all of the Rules and Regulations printed on this instrument or such

hereby made a part of this Lease. 

         7.       MAINTENANCE AND REPAIR. Lessee shall maintain the roof, 
exterior walls, and foundations of the Building in good repair, at its own

all times keep the Premises neat, clean, and in a safe and sanitary condition,
and remove all ice and snow therefrom, keep the glass and all windows and doors
thereof clean and presentable, maintain and keep the Premises and entries

thereof at the termination of this Lease, without disturbance, molestation or
injury. 

         11.      RESTRICTIONS. Lessee will not use or permit to be used in said
Premises anything that will increase the rate of insurance on the Building or

         12.      ACCESS. Lessee will allow and does hereby grant Lessor and/or
Lessor's agents the right of free access at all reasonable times to the Premises

Premises.

         13.      ATTORNEY'S FEES. In the event suit is brought to enforce any

business or property of Lessee and said appointment is not vacated within thirty
(30) days, Lessor may terminate this Lease, which termination shall reserve unto
Lessor all of the rights and remedies available under Paragraph 15 hereof, and
Lessor may accept rent from such assignee or receiver without waiving or
forfeiting said right of termination; that the filing in a court of competent

and terminate this Lease and Lessee shall immediately owe, and

                                      - 6 -



<PAGE>   7

the term hereof.
                           
         15.      ARREARAGES.  If any rent is in arrears for a period of ten 
(10) days after receipt by Lessee of written notice from Lessor of such alleged
arrearages, or if this Lease is terminated in accordance with any of the terms
herein (with the exception of Paragraph 13), or if Lessee shall fail at any
time to keep or perform any of the covenants or conditions of this Lease other
than the covenant for the payment of the monthly rent and such failure shall not
be cured within the ten (10) day period following receipt by Lessee of written
notice from Lessor of such alleged failure then, and in either or any of such
events, Lessor may, at Lessor's option, enter into and repossess the Premises
and remove from the Premises and expel all goods and effects without being
deemed guilty of trespass and/or without prejudicing any remedy or remedies
which might otherwise be used by Lessor for arrears of rent or preceding breach
of covenant or condition of this Lease, and upon entry as aforesaid, said term
if not otherwise terminated shall immediately cease and terminate and Lessee
shall be liable (in addition to any other damage arising under any other
paragraph hereof) to Lessor for any deficiency arising from reletting the
Premises at a lesser rental than agreed to herein. In the event of such re-entry
and repossession, Lessor shall have the right, but not the obligation, to remove
from the Premises all personal property located therein and may place the same
in storage in the Building

                                      - 7 -

         16.      RISK. All personal property of any kind or description 
whatsoever in the Premises shall be at the Lessee's sole risk and the Lessor
shall not be liable for any damage done to or loss of such personal property or
damage or loss suffered by the business or occupation of the Lessee arising from
any acts or neglect of Lessee, its agents, employees, servants, customers or
clients, or from bursting, overflowing or leaking of water, sewer or steam
pipes or from the heating or plumbing fixtures or from electric wires, or from
gas, odors, or caused in any other manner whatsoever.

cost and expense, shall carry and maintain:

                  (a) Comprehensive public liability insurance, such insurance
to afford protection in the minimum combined limit of not less than $5,000,000

reviews, with respect to injury or damaged persons or property.
     
                  (b) Fire insurance with extended coverage endorsement upon

                                     - 8 -
<PAGE>   9
                  (d) Such policies of insurance shall not be cancelable without
thirty (30) days prior written notice thereof to Lessor, and, at Lessor's
request, to any holder of a security interest in the Building, and shall name
Lessor and any such security holder, at Lessor's request, as an additional named
insured. Lessee shall submit a certificate of such policies to Lessor, and, at
Lessor's request, to any party holding a security interest in the Building. 

         18.      INDEMNIFICATION. Lessee will indemnify and hold harmless 
Lessor from any claim, liability or suit on behalf of any person, persons,
corporations and/or firms for any injuries or damages occurring in or about the
Premises or on or about the sidewalk, stairs, or thoroughfares adjacent thereto
where said damage or injury was caused or partially caused by the ordinary or
gross negligence or intentional act of Lessee and/or by Lessee's agents,
employees, servants, customers, or clients. 

         19.      DAMAGE OR DESTRUCTION. In the event the Premises are rendered 
untenantable in whole or in excess of twenty-five percent (25%) thereof by fire,
the elements, or other casualty, Lessor may elect, at its option, not to restore
or rebuild the Premises and shall so notify Lessee, in which event Lessee shall
vacate the Premises and this Lease shall be terminated; or, in the alternative,
Lessor shall notify Lessee, within thirty (30) days after the notice of such
casualty, that Lessor will undertake to rebuild or restore the Premises, and
that such work can be completed within one hundred eighty (180) days from the
date of

                                      - 9 -



<PAGE>   10

such notice. If Lessor cannot restore or rebuild the Premises within the said
one hundred eighty (180) days, then the Lease may be terminated at Lessee's
option by written ten- (10-) day notice to Lessor. During the period of 
untenantability, rent shall abate in the same ratio as the portion of the
Premises rendered untenantable bears to the whole of the Premises; provided,
that if the damage is due to the fault or neglect of Lessee, there shall be no
abatement of rent. 

         20.      EMINENT DOMAIN. If the whole of the Premises shall be taken by
any public authority under the power of eminent domain, or purchased by the
condemnor in lieu thereof, then the term of this Lease shall cease as of the
date possession is taken by such public authority. If only a part of the
Premises shall be so taken, the Lease shall terminate only as to the portion
taken, and shall continue in full force and effect as to the remainder of said
Premises, and the rent amount shall be reduced proportionately; provided,
however, if the remainder of the Premises cannot be made tenantable for the
purposes for which Lessee has been using the Premises, in Lessee's judgment, or
if more than twenty-five percent (25%) of the rentable square footage of the
Premises shall be so taken, then either party, by written notice to the other,
given at least thirty (30) days prior to the date that possession must be
surrendered to the public authority, may terminate this Lease effective as of
such surrender of possession. In the event of any such taking, whether whole
or partial, Lessor shall be entitled to any and all awards, settlements, or
compensation which may be given for the


                                     - 10 -
<PAGE>   11

land and buildings.  Lessee shall have no claim against Lessor for the value of
any unexpired term of this Lease.

         21.      SUBORDINATION. This Lease and all interest and estate of 
Lessee hereunder is subject to and is hereby subordinated to all present and
future mortgages and deeds of trust affecting the Premises. The Lessee agrees to
execute, at no expense to the Lessor, any instrument which may be deemed
necessary or desirable by the Lessor to further effect the subordination of this
Lease to any such mortgage or deed of trust. 

         22.      SIGN RESTRICTION. No sign, picture, advertisement or notice 
shall be displayed, inscribed, painted or affixed to any of the glass or
woodwork of the leased Building without the approval of Lessor, which approval
will not be unreasonably withheld. 

         23.      LOCKS. No additional locks shall be placed upon any doors of 
the Premises. Keys will be furnished to each door lock. At the termination of
the Lease, Lessee shall surrender all keys to the Premises. 

         24.      WAIVER OF SUBROGATION. Notwithstanding anything contained 
herein to the contrary, in the event of loss or damage to the Building, the
Premises and/or any contents herein, each party shall look first to any
insurance in its favor before making any claim against the other party; and to
the extent possible without additional cost, each party shall obtain for each
policy of such insurance, provisions permitting waiver of any claim against the
other party for loss or damage within the scope of the insurance company, and
each party, to such extent

                                     - 11 -



<PAGE>   12

permitted, for itself and its insurers, waives all such insured claims against
the other party.

         25.      REAL PROPERTY TAXES. Lessee agrees to reimburse Lessor for all
real property taxes on the Premises. Lessor shall notify Lessee promptly of
amounts owing and upon receipt of an increased assessment for the Premises, all
of which sum Lessee shall pay to Lessor no later than five (5) days before such
payments are due to the taxing authorities. Lessee shall be entitled to
challenge such increased assessment at its own expense. Lessee shall not be
obligated to pay any penalty for delinquent payment by Lessor of such taxes,
unless Lessee shall have failed to pay such sum due to Lessor as herein
provided. For any year in which the Lease terminates or expires before the end
of the calendar year, any reimbursement by Lessee hereunder shall be prorated.
Lessee shall be required to pay any assessments levied against the Premises in
accordance with this paragraph 25. Provided, however, that the Lessor shall be
required to elect, if possible, to pay such assessment in the maximum number of
installments allowed by law. 

         26.      HOLDING OVER. If Lessee holds possession of the Premises after
the term of this Lease, Lessee shall be deemed to be a month-to-month tenant
upon the same terms and conditions as contained herein.

         27.      NO REPRESENTATIONS. The Lessor has made no representations or
promises except as contained herein or in some further writings signed by
Lessor.

                                     - 12 -



<PAGE>   13

         28.      QUIET ENJOYMENT.  Lessor covenants that if and so long as 
Lessee pays the rent and performs the covenants contained in this Lease, Lessee
shall hold and enjoy the Premises peaceably and quietly, subject to the
provisions of this Lease. 

         29.      BINDING EFFECT.  The parties agree that each of the provisions
of this Lease shall extend to and shall, as the case may require, bind and inure
to the benefit of the parties and their respective heirs, legal representatives,
successors and assigns, subject, however, to the provisions covering assignment
and subletting of this Lease. It is also understood and agreed that the terms
"Lessor" and "Lessee" and verbs and pronouns in the singular number are
uniformly used throughout this Lease regardless of gender, number or fact of
incorporation of the parties hereto, The typewritten riders or supplemental
provisions, if any, attached or added hereto are made a part of this Lease by
reference. It is further agreed that no waiver by Lessor of a breach by Lessee
of any covenant or condition of this Lease shall be construed to be a waiver of
any succeeding breach of the same or any other covenant or condition.

                        FIRST AMENDMENT TO BUILDING LEASE


      THIS FIRST AMENDMENT TO BUILDING LEASE is made and entered into as of this
first day of January, 1997, by and between AUTOMATED RETAIL SYSTEMS, INC., a
Delaware corporation ("Lessee"), and Michael Pollastro, Gary T. Pollastro, and
John and Carmen Pollastro, husband and wife, tenants in common ("Lessor").

      On or about May 29, 1990, the parties hereto entered into that certain
Building Lease, a copy of which is attached hereto and incorporated by this
reference as if fully set forth herein (the "Lease"). The parties now desire to
amend the lease for the first time, as hereinafter provided.

      In consideration of the forgoing and other valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree to
amendment the Lease for the first time, as follows:

1.    Section 1 shall be restated in its entirety, as follows:

      1. DESCRIPTION. Lessor, in consideration of the agreements contained in
      this Lease, does hereby lease to Lessee, upon the terms and conditions
      hereinafter set forth, 11,158 square feet (as depicted on Schedule A
      attached) of that certain building commonly known as the Automated Retail
      Systems Building (the "Premises") situated upon the real property (the
      "Property") in the City of Seattle, State of Washington, legally described
      as follows:

            Lots 17, 18, 19, 20, 21, and 22, Block 26, Hill Tract Addition to
            the City of Seattle, Supplemental Plat, according to the plat
            recorded in Volume II of Plats, Page 51, in King County, Washington.

2.    Section 2 shall be restated in its entirety, as follows:

      2. TERM. The term of this Lease shall be for a period commencing upon the
      later of October 1, 1990, or Lessor's receipt of a certificate of
      occupancy for the Building, and ending on December 31, 2003.

3.    Section 3 shall be modified by adding the following sentence at the
      conclusion of the Section : "Notwithstanding the forgoing, from and after
      January 1, 1997, Lessee shall pay rent on the first day of each calendar
      month of FIFTEEN THOUSAND SIXTY-THREE AND 30/100 DOLLARS ($15,063.30),
      together with one-twelfth of the annual increase of the actual cost of
      taxes, insurance, utilities, and maintenance for the Premises in relation
      to the costs of such items for the calendar year 1996."

4.    Section 4 shall be modified by adding the following as the last sentence
      to the Section : "In the event Michael Pollastro shall not be president of
      the Lessee for any reason, the Lessee shall


                                       1
<PAGE>   16
      thereupon deposit with Lessor, as a security deposit, a sum equal to the
      rent due and payable as of the first day of the month immediately
      preceding the date of such change of officers."

5.    Section 7 shall be modified by imposing upon Lessor all obligations
      imposed upon Lessee in such section; provided, however, such modification
      shall not be deemed to relieve Lessee of its duty to "commit no waste of
      any kind."

6.    Section 8 shall be modified to impose upon Lessor the obligation to pay
      those items of cost identified in Subsection 8(a).

7.    Section 17 shall be modified by substituting "Lessor" for "Lessee" in line
      one thereof, and deleting the last sentence of Subsection 17(d).

8.    Section 21 shall be modified by restating the final sentence, as follows:
      "The Lessee agrees to execute, at no expense to the Lessor, any instrument
      which may be deemed necessary or desirable by the Lessor to further effect
      the subordination of this Lease to any such mortgage or deed of trust, or
      to allow an assignment of this Lease for security purposes to any lender
      providing financing with respect to the Property.

9.    Section 25 shall be restated in its entirety, as follows:

      25. REAL PROPERTY TAXES. Lessor shall pay all real property taxes on the
      Property and building. Lessee shall pay any personal property taxes
