continue through June 30, 2005.

      b) Possession: Tenant's right to possession and obligations under this
Lease shall commence on July 1, 1995.

II. RENT

      a) Basic Rent:

Tenant shall pay to Landlord as rent the sum of Seven Thousand and Fifty
($7,050.00) per month commencing the date Tenant is entitled to possession as
set forth above. Rent shall be payable on the 1st day of each month in advance
at such place as may be designated by Landlord.

      b) Escalation:

On May 25, 1999 and on the same day of every month of each succeeding year,
there shall be computed any increase in the cost of living based on the

                                       70
<PAGE>

and U.S. Average" (1967-100) hereinafter called the "Index", published by the
Bureau of Labor statistics of the U. S. Department of Labor. The Index number
for the city of Portland, Oregon entitled "All Items" for the month of July,
1995, to wit:_____, shall be the base Index number for purposes of computation.
The monthly basic rent set forth in Sub-paragraph (a) hereof shall, in the event
of an increase in the cost of living determined as above-mentioned, be increased
effective the 25th day of March of each succeeding calendar year during the term
of this Lease Agreement wherein there is an increase in said cost of living. The
current Index number shall be divided by the base Index number and half the
result multiplied by the basic monthly rental mentioned above shall be the
adjusted monthly rental. Landlord shall, within a reasonable time after
determining the appropriate information, with respect to said increase, give
Tenant notice of such increase, and Landlord's computation thereof shall be
binding and conclusive unless Tenant shall, within fifteen (15) days after the
giving of said notice, advise Landlord of any dispute in conjunction therewith.
Any dispute between the parties as to such computation shall be determined by a
Board of Arbitration with one member selected by Landlord and one member
selected by Tenant and one member selected by the selectees of Landlord and
Tenant. If publication of the Consumer Price Index shall be discontinued, the
parties shall thereafter accept comparable statistics on the cost of living for
the city of Portland as they shall be computed and published by any government
agency or by a responsible financial periodical of recognized authority. In the
event that any method is not utilizable and does not have an appropriate Index
for the given month that is herein involved, computation shall be undertaken in
the form of interpolation between given dates that are applicable so that the
spirit and intent of this paragraph can be given effect.

      b) Total Taking: If a condemning authority takes all of the leased

      c) Sale in Lieu of Condemnation: Sale of all or part of the leased
premises to a purchaser with the power of eminent domain in the face of a threat

      a) Liens:

      (1) Except with respect to activities for which Landlord is responsible,
      Tenant shall pay as due all claims for work done on, and for services
      rendered or material furnished to, the leased premises and shall keep the
      premises free from any liens. If Tenant fails to pay any such claims or to
      discharge any lien, Landlord may do so and collect the cost as additional
      rent. Any amount so added shall bear interest at the rate of Twelve
      percent (12%) per annum from the date expended by Landlord and shall be
      payable on demand. Such action by Landlord shall not constitute a waiver
      of any right or remedy which Landlord may have on account of Tenant's
      default.

      (2) Tenant may withhold payment of any claim in connection with a
      good-faith dispute over the obligation to pay, so long as Landlord's
      property interests are not jeopardized. If a lien is filed as a result of
      nonpayment, Tenant shall, within ten (10) days after knowledge of the
      filing, secure the discharge of the lien or deposit with Landlord cash or
      sufficient corporate surety bond or other surety satisfactory to Landlord
      in an amount sufficient to discharge the lien plus any costs, attorney
      fees, and other charges that could accrue as a result of a foreclosure or
      sale under the lien.

      b) Indemnification: Tenant shall indemnify and defend Landlord from any
claim, loss, or liability arising out of or related to any activity of Tenant on
the leased premises or any condition of the leased premises in the possession or
under the control of Tenant. Landlord shall have no liability to Tenant for any
loss or damage caused by third parties or by any condition of the premises.

      c) Liability Insurance: Before going into possession of the premises,
Tenant shall procure, and thereafter during the term of the Lease shall continue
to carry, the following insurance at Tenant's cost: public liability and
property damage insurance in a responsible company with limits of not less than
$1,000,000 for injury to one person, $1,000,000 for injury to two or more
persons in one occurrence, and $100,000 for damage to property. Such insurance
shall cover all risks arising directly or indirectly out of Tenant's activities
on or any condition of the leased premises whether or not related to an
occurrence caused or contributed to by Landlord's negligence, shall protect
Tenant against the claims of Landlord on account of the obligations assumed by
Tenant under this Lease; and shall protect Landlord and Tenant against claims of
third persons. Certificates evidencing such insurance and bearing endorsements


                                       75
<PAGE>

requiring ten (10) days' written notice to Landlord prior to any change or
cancellation shall be furnished to Landlord prior to Tenant's occupancy of the
property.

XI. ASSIGNMENT AND SUBLEASE

      No part of the leased property may be assigned, hypothecated, or
subleased, nor may a right of use of any portion of the property be conferred on
any third person by any other means, without the prior written consent of
Landlord. No consent in one instance shall prevent the provision from applying
to a subsequent instance.

XII. DEFAULT

The following shall be events of default:

      a) Default in Rent: Failure of Tenant to pay any rent or other charge
within 10 days after its due date.

      b) Default in Other Covenants: Failure of Tenant to comply with any term
or condition or fulfill any obligation of the Lease (other than the payment of
rent or other charges) within Twenty (2) days after written notice by Landlord
specifying the nature of the default with reasonable particularity. If the
default is of such a nature that it cannot be completely remedied within said
period, this provision shall be complied with if Tenant begins correction of the
default within said period and thereafter proceeds with reasonable diligence and
in good faith to effect the remedy as soon as practicable.

XIII. REMEDIES ON DEFAULT

      Upon the termination of this Lease, at its expiration by lapse of time or
otherwise, the Tenant shall yield up immediate possession to the Landlord.

      It is mutually agreed as a condition of this Lease, and the Tenant
covenants, that if there shall be a default as defined above, then and in each
and every case, the term hereby granted shall, at the election of the Landlord,
immediately thereupon cease, terminate and come to an end, without further
formality and without prejudice to Landlord's right to rents due or to become
due; and the Landlord may recover and resume possession of the demised premises
by any legal means; and in such case, the Landlord shall have the right to
re-enter upon said premises and resume possession of same and without prejudice
to any remedies which might otherwise be available to Landlord.

      It is understood and agreed that in the event of default of Tenant's
obligations as defined in this Agreement, so that Landlord resumes possession of
the subject real property and improvements thereon, the Tenant's obligations for
monthly installment payments shall not terminate; that each month's unpaid
installment shall constitute a separate cause of action for which the Landlord
may litigate independently. Any action or suit to recover possession of said
real property and improvements shall not terminate rent obligations due from
Tenant.


                                       76
<PAGE>

      The written notice of Landlord's intention to terminate this Lease
hereinabove provided for shall be deemed a re-entry under the law, as to all
rights between Landlord and Tenant herein, and upon any such resumption of
possession by the Landlord in any manner, Landlord may remove all persons and
property from the demised premises. Landlord may thereafter be entitled to hold
the Tenant liable for expenses incurred by the Landlord for necessary repairs to
the demised premises, so far as incumbent upon the Tenant to keep same in
repair, or by reason of the breach of any of the terms, conditions, or covenants
of this Lease, and all expenses incurred in recovering possession of the
premises and in reletting same to mitigate Landlord's loss.

XIV. SURRENDER AT EXPIRATION

      a) Condition of Premises: Upon expiration of the Lease term, or earlier
termination on account of default, Tenant shall deliver all keys to Landlord and
surrender the leased premises in first-class condition and broom clean.
Alterations constructed by Tenant with permission from Landlord shall not be
removed or restored to the original condition unless the terms of permission for
the alteration so require. Depreciation and wear from ordinary use for the
purpose for which Tenant is responsible shall not be charged against Tenant.
Excess use and damage shall be promptly remedied by Tenant, to be completed by
the latest practical date prior to surrender.

      b) Fixtures:

      (1) All fixtures placed upon the leased premises during the term, other
      than Tenant's trade fixtures, shall, at Landlord's option, become the
      property of Landlord. If Landlord so elects, Tenant shall remove any or
      all fixtures which would otherwise remain the property of Landlord, and
      shall repair any physical damage resulting from the removal. If Tenant
      fails to remove such fixtures, Landlord may do so and charge the cost to
      Tenant with interest at the legal rate from the date of expenditure.

      (2) Prior to expiration or termination of the Lease term Tenant shall
      remove all furnishings, furniture, and trade fixtures which remain
      Tenant's property. If Tenant fails to do so, this shall be an abandonment
      of the property.

      c) Holdover:

      (1) If Tenant does not vacate the leased premises at the time required,
      Landlord shall have the option to treat Tenant as a tenant from
      month-to-month, subject to all of the provisions of this Lease, except the
      provisions for term and renewal, and at a rental rate equal to One Hundred
      and Ten Percent (110%) of the rent last paid by Tenant during the original
      term. Failure of Tenant to remove fixtures, furniture, furnishings, or
      trade fixtures which Tenant is required to remove under this Lease, shall
      constitute a failure to vacate to which this paragraph shall apply if the
      property not removed will substantially interfere with occupancy of the
      premises by another tenant or with occupancy by Landlord for any purpose,
      including preparation for a new tenant.


                                       77
<PAGE>

      (2) If a month-to-month tenancy results from a holdover by Tenant under
      this Subsection, the tenancy shall be terminable at the end of any monthly
      rental period on written notice from Landlord given not less than Thirty
      (30) days prior to the termination date which shall be specified in the
      notice. Tenant waives any notice which would otherwise be provided by law
      with respect to a month-to-month tenancy.

XV. MISCELLANEOUS

      a) Nonwaiver: Waiver by either party of strict performance of any
provision of this Lease shall not be a waiver of or prejudice the party's right
to require strict performance of the same provision in the future, or of any
other provision.

      b) Attorney Fees: If suit or action is instituted in connection with any
controversy arising out of this Lease, the prevailing party shall be entitled to
recover, in addition to costs, such sum as the Court may adjudge reasonable as
attorney fees at trial and on appeal.

      c) Notices: Any notice required or permitted under this Lease shall be
deemed given when actually delivered, or forty-eight (48) hours after deposited
in the United States mail as certified Mail addressed to the address first given
in this Lease, or to such other address as may be specified from time to time by
either of the parties in writing.

      d) Succession: Subject to the above-stated limitations on transfer of
Tenant's interest, this Lease shall be binding upon and inure to the benefit of
the parties, their respective successors or assigns, subject to the above
restrictions on assignment.
