    30 days and thereafter diligently prosecutes the cure to completion, then
    the Lessor may cancel this Lease in its entirety including but not limited
    to all options, upon giving notice required by law, and re-enter said
    Premises, but not withstanding such re-entry by Lessor, the liability of
    the Lessee for the rent and other obligations provided herein shall not be
    extinguished for the balance of the term of the Lease, and Lessee covenants
    and agrees to make good to Lessor any deficiency arising from a re-entry
    and reletting of the Premises at a lesser rental than therein agreed to.
    The Lessee shall pay such deficiency each month as the amount is
    ascertained by Lessor.  In the event Lessor re-enters the Premises, the
    cost of restoration and placing the Premises in a condition suitable for
    tenancy shall be added to any deficiency arising from such re-entry
    (ordinary wear and tear excepted).

25. EMINENT DOMAIN


                                          12


    (a)  Total Condemnation - If the whole of the Leased Premises shall be
    acquired or condemned by eminent domain for any public or quasi-public use
    or purpose, then the term of this Lease shall cease and terminate as of the
    date title or possession shall be transferred to such proceeding, whichever
    shall first occur, and all rentals shall be paid up to that date and Lessee
    shall have no claim against Lessor for the value of any unexpired term of
    this Lease.

    (b)  Partial Condemnation - If any part of the Leased Premises or the
    building in which the Leased Premises are situated shall be acquired or
    condemned by eminent domain for any public or quasi-public use or purpose
    and in the event that such partial taking or condemnation shall render the
    Leased Premises unsuitable for the business of the Lessee, then the term of
    this Lease shall cease and terminate as of the date title or possession
    shall be transferred in such proceeding, whichever shall first occur, and
    Lessee shall have no claim against Lessor for the value of any unexpired
    term of this Lease.  In the event of a partial taking or condemnation which
    is less than twenty percent (20%) of the premises and not extensive enough
    to render the Premises unsuitable for the business of the Lessee, then
    Lessor shall promptly restore the Leased Premises to a condition comparable
    to its condition at the time of such condemnation, less the portion lost
    and rental adjusted accordingly in the taking, and this Lease shall
    continue in full force and effect.  If the parties are unable to agree on
    the issue of the suitability of the remaining portion of the Premises, the
    same shall be submitted to binding arbitration during which period the
    Lease shall remain in effect except that the rental shall be partially
    abated as herein set forth.  Initially the parties shall attempt to agree
    upon one arbitrator..  Any arbitrator selected under this paragraph must be
    a commercial Realtor doing business in King County Washington.  If the
    parties are unable to agree upon one arbitrator within fourteen (14) days,
    each party shall name one arbitrator and the two so selected arbitrators
    shall select a third arbitrator.  If the two arbitrators fail to name a
    third arbitrator within a reasonable period of time, the third arbitrator
    shall be selected by the Presiding Judge of the Superior Court of the State
    of Washington for King County at the request of either Lessor or Lessee.
    The costs of arbitration shall be borne equally between the parties and the
    determination by the arbitrator shall be binding upon the parties and not
    subject to further legal proceedings.

    (c)  Lessor's Damages- In the event of any condemnation or taking as
    hereinbefore provided, whether whole or partial,


                                          13


    the Lessee shall not be entitled to any part of the award, as damages or
    otherwise, for such condemnation, and Lessor is to receive the full amount
    of such award, the Lessee hereby expressly waiving an right of claim to any
    part thereof.

    (d)  Lessee's Damages - Although all damages in the event of any
    condemnation are to belong to the Lessor, whether such damages are awarded
    as compensation or diminution of value of the Leasehold or the fee, Lessee
    shall have the right to claim and recover such compensation as may be
    separately awarded or recoverable by Lessee in Lessee's own right on
    account of any condemnation for or on account of any cause or loss to which
    Lessee might be put in removing Lessee's inventory, Leasehold improvements
    or equipment.

26. WAIVER OF SUBROGATION

    Lessor hereby reLeases Lessee of and from every and all right, claim and
    demand that Lessor may hereafter have against Lessee, or Lessee's
    successors or assigns, arising out of or in connection with any loss or
    losses occasioned by fire and such perils as are included under the normal
    extended coverage clauses of fire insurance policies, and sustained by
    Lessor in or around the Premises.  Lessee hereby releases Lessor from any
    and every right, claim and demand that Lessee may hereafter or in
    connection with any loss or losses occasioned by fire and such perils as
    are included in the normal extended coverage clauses of fire insurance
    policies, and does hereby waive all rights of subrogation in favor of
    insurance carriers against Lessor arising out of any losses occassioned by
    fire, and such perils as are included under the normal extended coverage
    clauses of fire insurance policies, and sustained by Lessee to its trade
    fixtures, equipment and inventory.

27. SUBORDINATION

    This Lease and the Leasehold improvements therein are subject to and are
    hereby subordinated to all present and future mortgages, deeds of trust and
    other encumbrances affecting the demised Premises or the property of which
    the demised Premises are a part; provided however, that the mortgagee's
    beneficiaries or encumbrance holders shall agree to recognize the term of
    this Lease and not to disturb the


                                          14


    tenancy created hereby.  The Lessee agrees to execute, at no expense to the
    Lessor, instruments which may be needed, necessary or desirable by the
    Lessor which instruments shall effect the subordination of this Lease to
    any mortgage, deed of trust or encumbrance.

28. HOLDOVER

    If the Lessee shall, with the written consent of Lessor, hold over after
    the expiration of the term of this Lease, such tenancy shall be for an
    indefinite period of time on a month-to-month tenancy, which tenancy may be
    terminated as provided by the laws of the State of Washington.  During such
    tenancy, Lessee agrees to pay to the Lessor one and one-half (1 1/2) times
    the rent for the last month of the base term, and to be bound by all the
    terms, covenants, and conditions as herein specified, so far as applicable.

29. ESTOPPEL CERTIFICATES

    Lessee agrees at any time and from time to time upon no less than twenty
    (20) days prior notice by Lessor to execute and deliver to Lessor a
    statement in writing, addressed to Lessor, certifying that this Lease is
    unmodified and in full force and effect, or, if there have been
    modifications, that the same is in full force and effect as modified and
    stating modifications, stating the dates to which rental has been paid, and
    stating whether to the best knowledge of Lessee, there is any default under
    the terms and conditions of the Lease, and if so, specifying each such
    defect, it being intended that any such statement delivered pursuant hereto
    may be relied upon by Lessor and by mortgagee or prospective mortagee of
    any mortgage affecting the building or the building and the land.

30. ATTORNMENT

    If any proceedings are brought for the foreclosure of any encumbrance
    affecting the demised Premises, or the power of sale under any deed of
    trust made by Lessor covering the demised Premises, Lessee shall attorn to
    the Purchaser upon any such foreclosure of sale and recognize such
    Purchaser as Lessor under this Lease, provided however, that unless Lessee
    shall be in default, any such attornment or subordination as provided in
    this Lease shall not affect the possessory rights of Lessee under the terms
    of this Lease, and Lessee's use and quiet enjoyment of the premises shall
    continue undisturbed.

31. AUTHORITY OF PARTIES


                                          15

    of said corporation represents and warrants that he is duly authorized to
    execute and deliver this Lease on behalf of said corporation, in accordance
    with a duly adopted resolution of the Board of Directors of said
    corporation or in accordance with the bylaws of said corporation, and that
    this Lease is binding upon said corporation in accordance with its terms.

32. GENERAL PROVISIONS

    (a)  Waiver - the waiver by either party of any term, covenant or condition
    herein contained shall not be deemed to be a waiver of such term, covenant
    or condition or any subsequent breach of the same or any other term,
    covenant or condition herein contained.  The subsequent acceptance of rent
    hereunder by either party shall not be deemed to be a waiver of any
    preceding breach by either party of any term, covenant or condition of this
    Lease, other than the failure of Lessee to pay the particular rental so
    accepted, regardless of Lessor's knowledge of such preceding breach at the
    time of acceptance of such rent.

    (b)  Notices - All notices and demands which may or are to be required or
    permitted to be given by either party to the other hereunder shall be in
    writing.  All notices and demands by Lessor to Lessee shall be sent by
    United States Mail, postage prepaid, and certified with return receipt
    requested, addressed to Lessee at the Leased premises or to such other
    place as Lessee may from time to time designate in a notice to Lessor.  All
    notices and demands by Lessee to Lessor shall be sent by United States
    Mail, postage prepaid, addressed to Lessor HRP PROPERTIES 1 at Post Office
    Box 700, Mercer Island, Washington, 98040, or to such other person or place
    as Lessor may from time to time designate in a notice to Lessee.  Notices
    are effective three days after mailing.

    (c)  Marginal Headings - The marginal headings and paragraph titles of this
    Lease are not a part of this Lease and shall have no effect on the
    construction or interpretation of any part hereof.

    (d)  Time - Time is of the essence of this Lease and each and all of its
    provisions in which performance is a factor.

    (e)  Successors  and Assigns - The covenants and conditions herein
    contained, subject to the provisions as to assignment, apply to and bind
    the heirs, successors, executors, administrators and assigns of the parties
    hereto.


                                          16


    (f)  Recordation - Neither Lessor nor Lessee shall record this Lease or a
    short form memorandum hereof without the prior written consent of the other
    party.

    (g)  Quiet Possession - Upon Lessee paying the rent reserved hereunder and
    observing and performing all of the covenants, conditions and provisions on
    Lessee's part to be observed and performed hereunder, Lessee shall have
    quiet possession of the Premises for the entire term hereof, subject to all
    the provisions of this Lease.

    (h)  Late Charges - Lessee hereby acknowledges that late payment by Lessee
    to Lessor of rent or other sums due hereunder will cause Lessor to incur
    costs not contemplated by this Lease, the exact amount of which will be
    extremely difficult to ascertain.  Such costs include but are not limited
    to, processing and accounting charges, and late charges which may be
    imposed upon Lessor by terms of any mortgage or trust deed covering the
    Premises.  Accordingly, if any installment of  rent or of a sum due from
    Lessee shall not be received by Lessor or Lessor's assignee, in the event
    of rent on the tenth (10th) of the month, or in the event of any other sum
    due within ten (10) days after written demand, then Lessee shall pay to
    Lessor a late charge equal to six percent (6%) of such overdue amount.
    However, if said period be extended beyond fifteen (15) days, then Lessee
    shall pay to Lessor a late charge equal to twelve percent (12%) per annum
    of such overdue amount.  The parties hereby agree that such late charges
    represent a fair and reasonable estimate of the cost that Lessor will incur
    by reason of the late payment by Lessee.  Acceptance of such late charges
    by Lessor shall in no event constitute a waiver of Lessee's default with
    respect to such overdue amount, nor prevent Lessor from exercising any of
    the other rights and remedies granted hereunder.

    (i)  Prior Agreements - This Lease contains all of the agreements of the
    parties hereto with respect to any matter covered or mentioned in this
    Lease, and no prior agreements or understanding pertaining to any such
    matters shall be effective for any purpose.  No provision of this Lease may
    be amended or added to except by an agreement in writing signed by the
    parties hereto to their respective successors of interest.  This Lease
    shall not be effective or binding on any party until fully executed by both
    parties hereto.

    (j)  Variation in Pronouns - All pronouns and variations thereof shall be
    deemed to refer to the


                                          17


    masculine, feminine, singular or plural as the identity of the person or
    persons may require.

    (k)  Inability to Perform - This Lease and the obligations of the Lessee
    hereunder shall not be affected or impaired because the Lessor is unable to
    fulfill any of its obligations hereunder or is delayed in doing so, if such
    inability or delay is caused by reason of strike, labor troubles, acts of
    God, or any other cause beyond the reasonable control of the Lessor.

    (l)  Separability - Any provisions of this Lease which shall prove to be
    invalid, void or illegal shall in no way affect, impair, or invalidate any
    other provisions hereof and such other provisions shall remain in full
    force and effect.

    (m)  Cumulative Remedies - No remedy or election hereunder shall be deemed
    exclusive but shall, whenever possible, be cumulative with all other
    remedies at law or in equity.

    laws of the State of Washington as they exist on even date.
