                           SECOND AMENDMENT TO OFFICE LEASE


       THIS SECOND AMENDMENT TO OFFICE LEASE (this "Agreement") is made the 30
day of August, 1998, by and between MURRAY OREGON EQUITIES, L.L.C. , an Oregon
limited liability company (the "Lessor") and CORILLIAN CORPORATION, an Oregon
corporation (the "Lessee").

RECITALS.

       A.     Lessor entered that certain Office Lease dated March 20, 1996,
with CheckFree Corporation, an Ohio corporation (the "Initial Lease"), the
lessee's interest of which was assigned by Assignment of and Consent to
Assignment of Lease, dated May 15, 1997, to Lessee. The Initial Lease has been
amended by that certain First Amendment to Office Lease between Lessor and
Lessee of even date herewith (the "First Amendment").  As used in this
Agreement the term "Lease" means the Initial Lease as amended by the First
Amendment.  The Lease pertains to office space in a project known as the Murray
Business Center (the "Project"), which space is more particularly described in
the Lease.  Terms with initial capitals used in this Agreement, unless
otherwise defined, shall have the meanings given them in the Lease.

       B.     Lessee has advised Lessor that it desires to lease certain
expansion space in Building 3 of the Project consisting of approximately 8,801
useable square feet and 9,522 rentable square feet, as outlined in Exhibit A to
this Agreement (the "Expansion Space") provided that Lessee can occupy the
Expansion Space not later than February 1, 2000.  Lessor is willing to lease
the Expansion Space to Lessee on the terms and subject to the conditions set
forth in the Lease, and on the further terms and subject to the further
conditions set forth in this Agreement.

AGREEMENT.

       NOW, THEREFORE, in consideration of the premises and of the mutual
covenants contained herein, the parties agree:

       1.     TERM.  Commencing on the date determined pursuant to this Section
1, and continuing for the remaining term of the Lease, Lessor shall lease to
Lessee and Lessee shall lease from Lessor the Expansion Space.  The foregoing
lease of the Expansion Space shall commence, if at all, between the period of
July 1, 1999 and February 1, 2000, on the date (the "Expansion Space
Commencement Date") that is the thirtieth (30th) day following Lessor's written
notice (the "Expansion Space Notice") to Lessee stating that the Expansion
Space will be ready for occupancy by the thirtieth (30th) day following the
date of such notice (which notice shall not be given before June 1, 1999, or
after January 1, 2000); provided, that the Expansion Space Commencement Date
shall be extended, but not beyond February 1, 1999, one day for each day after
the thirtieth (30th) day following the Expansion Space Notice


                                                                          PAGE 1

<PAGE>

that Nike, Inc., the existing tenant in the Expansion Space, actually vacates
the same.  Lessor shall use commercially reasonable efforts to keep Lessee
advised, from time to time after execution of this Agreement, concerning the
date on which Lessor anticipates that the Expansion Space will be available.
If Lessor anticipates that the Expansion Space will be available for occupancy
before July 1, 1999, Lessor shall so advise Lessee, and upon the parties'
written agreement, the lease of the Expansion Space hereunder may commence
before July 1, 1999.  If for any reason Lessor has not given Lessee the
Expansion Space Notice on or before January 1, 2000, or the Expansion Space
Commencement Date does not occur by February 1, 1999, then this Agreement shall
terminate automatically and be of no further force and effect.

       2.     RENT.  Effective upon the Expansion Space Commencement Date,
Section 3 of the Lease shall be amended to substitute the following for the
corresponding portion of the table appearing therein:

</TABLE>

The minimum monthly rent due in respect of the Expansion Space for the month in
which the Expansion Space Commencement Date occurs shall be prorated (at the
rate of $366.70 per day) if the Expansion Space Commencement Date occurs other
than on the first day of such month.

       3.     PREPAID RENT AND SECURITY DEPOSIT.  Within ten (10) days
following Lessee's receipt of the Expansion Space Notice, Lessee shall deliver
to Lessor the sum of $22,002.00, consisting of prepayment of the first month's
minimum rent for the Expansion Space, and a further security deposit of
$11,001.00. Upon delivery of such sum, the term "Security Deposit" used in the
Lease shall mean such $11,001.00 PLUS the $14,344.00 already held by Lessor as
a security deposit thereunder, and Lessee's obligation, if any, to replenish
the Security Deposit shall extend to the full $25,345.00 thereof.

       4.     PARKING.  Effective upon the Expansion Space Commencement Date,
Section 4 of the First Amendment shall be amended to substitute the number
fifty-one (51) for the number thirty-four (34) each instance that it appears
therein.


                                                                          PAGE 2

<PAGE>

       5.     WORK LETTER AGREEMENT.  Not later than the Expansion Space
Commencement Date, Lessor shall complete certain improvements to the Expansion
Space consisting of the following:

              A.      Lessor shall construct a doorway on the ground floor of
the Project, giving access from the Expansion Space to the elevator lobby.

              B.     Lessor shall paint the stairwell giving access to the
Expansion Space in Lessee's choice of a standard color established for use in
the Project.

Except for the improvements described in this Section 5, the Expansion Space
shall be delivered to Lessee "As Is," in its condition existing on the date
that Nike, Inc., vacates the same.

       6.     PREMISES.  Effective upon the Expansion Space Commencement Date,
the term "Premises" as used in the Lease shall mean the original "Premises" as
defined at Section 1 of the Lease, and the Expansion Space.

       7.     RATIFICATION.  Except to the extent expressly amended hereby, the
Lease, and each of its terms and provisions, is hereby ratified and confirmed
in all respects and shall remain in full force and effect and unmodified.

       IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date and year first above written.

                       FIRST AMENDMENT TO OFFICE LEASE


       THIS FIRST AMENDMENT TO OFFICE LEASE (this "Agreement") is made the 23
day of June, 1998, by and between MURRAY OREGON EQUITIES, L.L.C., an Oregon
limited liability company (the "Lessor") and CORILLIAN CORPORATION, an Oregon
corporation (thc "Lessee").

RECITALS.

       A.     Commercial Real Estate Company, LLC, a Washington limited
liability company and CheckFree Corporation, an Ohio corporation entered that
certain Office Lease dated March 20, 1996 (the "Lease"), the lessee's interest
of which was assigned by Assignment of and Consent to Assignment of Lease, dated
May 15, 1997, to Lessee, and the lessor's interest of which has been assigned
and transferred to Lessor.  The Lease pertains to 11,350 square feet of useable,
and 12,280 square feet of rentable, office space, in a project known as the
Murray Business Center (the "Project"), which space is more particularly
described in the Lease.  Terms with initial capitals used in this Agreement,
unless otherwise defined, shall have the meanings given them in the Lease.

       B.     Lessee has advised Lessor that it desires to extend the term of
the Lease, which currently expires February 28, 1999, for an additional period
of six years.  Lessor is willing to grant such extension on the terms and
subject to the conditions set forth in this Agreement.

AGREEMENT.

NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties agree:

       1.     TERM.  Section 2 of the Lease is hereby amended to substitute the
date, February 28, 2005, for the date February 28, 1999, appearing therein.

       2.     MONTHLY MINIMUM RENT.  Section 3 of the Lease is hereby amended to
add, to the table appearing therein, the following:

<TABLE>
<CAPTION>
                  Months         Monthly Minimum Rent

                   85-96             $16,144.00
                   97-108            $16,628.00
</TABLE>


                                                                         PAGE 1

<PAGE>

       3.     PREPAID RENT AND SECURITY DEPOSIT.  Section 4 of the Lease is
hereby deleted in its entirety and the following is substituted therefor:

              "Lessee has delivered to Lessor, and Lessor currently
       holds, $14,344.00 which amount shall be held by Lessor under such
       section shall no longer be applied in payment of the last month's
       rent under this Lease but shall be held by Lessor as a security
       deposit for Lessee's due and prompt performance of each of its
       obligations under the Lease (the "Security Deposit").  If Lessee
       fails to perform any of its obligations under this Lease, then
       Lessor shall be entitled, without terminating this Lease and
       without limiting any other right it may have under this Lease or
       under applicable law, to apply all or any part of the Security
       Deposit to cure such failure or to compensate Lessor for any loss
       caused by Lessee's failure to perform.  Following Lessor's
       application of the Security Deposit in accordance with the
       preceding sentence, Lessee shall be obligated, upon receipt of
       Lessor's demand therefore, to restore the Security Deposit to
       $14,344.00 unless such application has occurred following
       expiration of the term of the Lease.  Upon expiration of the term
       of the Lease, after applying the Security Deposit in the manner
       permitted by this Section 4, Lessor shall refund to Lessee the
       Security Deposit net of such amounts that have been applied.
       Lessor may, upon transfer of its interest in the Lease, transfer
       the Security Deposit to its assignee and upon any such transfer
       Lessor shall be released and discharged from any further
       obligation or liability to Lessee with respect to the Security
       Deposit."

       4.     PARKING.  From and after the date of this Agreement, Lessee shall
have the right to use up to thirty-four (34) parking spaces in the outside
parking lot that forms a part of the Project, which use shall be subject to and
shall comply in all respects with rules and regulations from time to time
established by Lessor for the use of such lot.  Lessee shall have no right in
any particular parking space but rather shall the right to use up to thirty-four
(34) spaces, on a first-come-first-served basis, with others who enjoy parking
privileges in the lot.

       5.     WORK LETTER AGREEMENT.  The Lease is hereby amended to provide
that not later than commencement of the thirty-seventh (37th) month of the Lease
term, Lessor shall complete certain improvements to the Premises consisting of
the following:

              A.     Lessor shall install one or more light fixtures in the
Project stairwell that leads to the Premises, as and to the extent appropriate,
in the exercise of Lessor's discretion, to reasonably enhance the lighting of
such stairwell and entry.

              B.     Lessor shall install carpeting in the ground-floor entryway
to the Premises over the parquet flooring currently existing in that entryway.

              C.     Lessor shall supply and install in the Premises an
ice-maker and dishwasher, which appliances shall, upon installation, be and
remain Lessor's sole property but shall be available for use by Lessee during
the term of this Lease.


                                                                         PAGE 2

<PAGE>

Lessor shall perform the work under this Section 5 during normal business hours
following reasonable advance notice to Lessee.  Except as set forth in this
Section 5, the Premises shall be delivered to Lessee "As Is" at commencement of
the thirty-seventh month of the Lease term, in its condition existing at that
time.

       6.     ASSIGNMENT AND SUBLETTING.  Section 13 of the Lease is hereby
amended as set forth in this Section 6.  In connection with requesting Lessor's
consent to an assignment or subletting of all or any part of the Premises,
Lessee shall deliver to Lessor a statement setting forth the proposed terms of
the subletting or assignment, together with such background information
concerning the proposed assignee or subtenant as Lessor may reasonably request
(which information shall include, at a minimum, the name and state of
organization of the proposed subtenant or assignee, the name of the executive
officers or managers of the proposed subtenant or assignee, a description of the
business in which the proposed subtenant or assignee is engaged and will engage
in at the Premises, and financial statements for the proposed subtenant or
assignee for the prior two fiscal years consisting, at a minimum, of a balance
sheet and statements of profit and loss).  Lessor's 20-day period under Section
13 of the Lease, to consent to such subletting or assignment, or to recapture
the portion of the Premises proposed to be sublet or assigned, shall commence
only when all of the foregoing information has been provided.  If Lessor does
not elect to recapture the Premises (or applicable portion thereof) in
accordance with its rights under Section 13, as amended hereby, then Lessor
shall not unreasonably withhold its consent to the proposed subletting or
assignment.  To the extent that any subletting or assignment permitted to be
made under Section 13, as amended hereby, results in the payment to Lessee of
any amount that exceeds Lessee's obligation of payment to Lessor under the
Lease, then Lessee shall pay one-half of such excess, upon receipt, to Lessor as
additional rent under the Lease.  Notwithstanding any provision of Section 13
seemingly to the contrary, in no event shall Lessee (a) advertise the Premises
or any part thereof for subletting or assignment at a rental rate that is lower
than the rental rates then being charged in the Project for comparable space,
(b) assign the Lease or sublease the Premises, or any portion thereof, to
another tenant in the Project, or (c) assign the Lease or sublet the Premises,
or any portion thereof, to any third party with whom Lessor has, within the
twelve (12) months preceding such assignment or subletting, negotiated
concerning a lease in the Project.  If Lessor exercises its right under Section
13, as amended hereby, to recapture the Premises, or the portion thereof that
Lessee proposes to sublease or assign, Lessee shall pay Lessor's managing agent,
at the effective date of such recapture by Lessor, a leasing commission for two
and one-half percent (2.5%) of the aggregate minimum annual rent payable in
respect of such space during the remaining Lease term.

       7.     RATIFICATION.  Except to the extent expressly amended hereby, the
Lease, and each of its terms and provisions, is hereby ratified and confirmed in
all respects and shall remain in full force and effect and unmodified.


                                                                         PAGE 3

       IN WITNESS WHEREOF, the parties have executed this Agreement as of the

                   ASSIGNMENT OF AND CONSENT TO ASSIGNMENT OF LEASE

This Assignment of and Consent to Assignment of Lease is made on this 15 day
of May, 1997, between COMMERCIAL REAL ESTATE COMPANY, LLC, ("Lessor"), whose
address is 1001 Fourth Avenue, Suite 4700, Seattle, Washington  98154, and
CHECKFREE CORPORATION, whose address is 3601 SW Murray Boulevard, Suite 300,
Beaverton, OR 97005, ("Assignor") and CORILLIAN CORPORATION, whose address is
3601 SW Murray Boulevard, Suite 300, Beaverton, OR  97005 ("Assignee"), who
agree as follows:

1.     RECITALS.  This Assignment of Lease is made with reference to the
       following facts and objectives:

       a.     Lessor and Assignor, as Lessee, entered into a written Lease dated
              March 20, 1996, (the "Lease"), in which Lessor leased to Assignor
              and Assignor leased from Lessor Premises located in the city of
              Beaverton, County of Washington, Oregon, commonly known as 3601 SW
              Murray Boulevard, Suite 300, Beaverton, OR  97005.

       b.     Assignor desires to assign all of its right, title and interest in
              the Lease to Assignee ("Assignment").

       c.     Lessor shall consent to the proposed Assignment on the conditions
              set forth in this Assignment.

2.     EFFECTIVE DATE OF ASSIGNMENT.  The Assignment in this Agreement shall
       take effect on May 15, 1997, and Assignor shall give possession of
       the Premises to Assignee on that date.

3.     ASSIGNMENT AND ASSUMPTION.  Assignor assigns and transfers to Assignee
       all of its right, title and interest in the Lease, and Assignee accepts
       the Assignment and assumes and agrees to perform, from the date the
       Assignment becomes effective, as a direct obligation to Lessor, all of
       the provisions of the Lease.

4.     LESSOR'S CONSENT.  Lessor consents to the Assignment without waiver of
       the restrictions in the Lease concerning further assignment or
       subleasing.

5.     ASSIGNOR'S LIABILITY.  Assignor shall remain primarily liable for the
       performance of the provisions and obligations under the Lease, including
       without limitation all obligations existing as of the date of this
       Agreement.  Anything in this agreement to the contrary notwithstanding,
       Assignor's obligations under the Lease remain as a direct obligation of
       Assignor to Lessor.  Lessor's willingness to accept performance by
       Assignee of Assignor's obligations does not affect the direct obligation
       of Assignor


                                                                          PAGE 1

<PAGE>

       to Lessor.  Upon a default by Lessee, Lessor may file suit directly
       against Assignor whether or not Lessor is enforcing its remedies
       against Assignee.

6.     ASSIGNEE TO HOLD ASSIGNOR HARMLESS.  If Assignee defaults under the
       Lease, Assignee shall indemnify and hold Assignor harmless from all
       damages, including reasonable attorney's fees and costs of suit, at trial
       and on appeal, resulting from the default.  If Assignee defaults in its
       obligations under the Lease and Assignor pays rent to Lessor or fulfills
       any of Assignee's other obligations in order to prevent Assignee from
       being in default, Assignee immediately shall reimburse Assignor for the
       amount of rent or costs incurred by Assignor in fulfilling Assignee's
       obligations under the Assignment of Lease, together with interest on
       those sums at the rate provided for in the Lease for interest on late
       payments.

7.     DEFAULT OF LEASE:  NOTICE TO ASSIGNOR.  Lessor will send any notice of
       default to both Assignor and Assignee.

8.     PREPAID RENT:  SECURITY DEPOSIT AND LAST MONTH'S RENT.  The parties
       acknowledge that Lessor now holds the sum of $14,344.00, of which $0 is a
       security deposit and $14,344.00 is to be applied to last month's rent,
       subject to the provisions of the Lease.  Assignor releases all claims to
       that sum, and the sum shall be held by Lessor for the benefit of
       Assignee, subject to the provisions of the Lease.

9.     AMENDMENT OF LEASE.  Lessor and Assignee shall not enter into any
       agreement that amends the material items and obligations pursuant to the
       Lease without notice to Assignor.  If Lessor and Assignee amend the Lease
       and Lessor fails to give notice to Assignor, such failure shall not
       release Assignor from its obligation on any unamended portions of the
       Lease.  In such event Assignor will remain liable under the Lease and
       this Agreement as if such amendment had not been made.

10.    MISCELLANEOUS.

       a.     ATTORNEYS' FEES.  If any party commences an action against any of
              the other parties arising out of or in connection with this
              Assignment of Lease, the prevailing party or parties shall be
              entitled to recover from the losing party or parties reasonable
              attorney's fees and costs of suit, at trial or on appeal.

       b.     NOTICE.  Any notice, demand, request, consent, approval or
              communication that any party desires or is required to give to any
              other party or any other person shall be given in the manner
              provided for notices in the Lease at the address set forth in the
              introductory paragraph of this Assignment.  Either party may
              change its address by notifying the other party of the change of
              address in writing.


                                                                          PAGE 2

       c.     SUCCESSORS.  This Assignment shall be binding on and inure to the

7      RULES AND REGULATIONS. Lessee agrees to comply with the Rules and
       Regulations attached hereto as Exhibit C, as well as such other
       reasonable rules and regulations as may from time to time be adopted by
       Lessor for the management, good order and safety of common areas, the
       building and its Lessee(s).  Lessee shall be responsible for the
       compliance with such rules and regulations by its employees, agents and
       invitees. Lessor's failure to enforce any of such rules and regulations
       against Lessee or any other Lessee shall not be deemed to be a waiver of
       same.

8.     MAINTENANCE AND REPAIRS.

              a.  LESSEE OBLIGATIONS. By entry hereunder, Lessee accepts the
       Premises as being in good and sanitary order, condition and repair.
       Lessee shall, at its expense, keep, maintain and preserve the Premises in
       first class condition and repair, and shall make all repairs to the
       Premises and every part thereof.  Lessee shall, upon the expiration or
       sooner termination of the term hereof, surrender the Premises to Lessor
       in the same condition as when received, usual and ordinary wear and tear
       excepted.  Lessee shall not alter, remodel, improve, repair, decorate or
       paint the Premises or any part thereof without first obtaining the prior
       written permission of Lessor.

              b.  LESSOR OBLIGATIONS.  Notwithstanding Section 8a, Lessor shall
       repair and maintain the structural portions of the Building and the
       plumbing, heating, ventilating, air conditioning, elevator and electrical
       systems furnished by Lessor; the costs of the foregoing shall be
       Operating Expenses, unless such maintenance and repairs are caused by the
       act, neglect or omission of Lessee, its agents, servants, employees or
       invitees, in which case Lessee shall pay to Lessor, as additional rent,
       the cost of such maintenance and repairs.  Lessor shall not be liable for
       any failure to make any such repairs or to perform any maintenance unless
       such failure shall persist for an unreasonable time after written notice
       of the need of such repairs or maintenance is given to Lessor by Lessee.
       There shall be no abatement of rent and no liability of Lessor by reason
       of any injury to or interference with Lessee's business arising from the
       making of any repairs, alterations or improvements in or to any portion
       of the Building or the Premises or in or to fixtures, appurtenances and
       equipment therein.  Lessee waives the right, if any, to make repairs at
       Lessor's expense under any law, statute or ordinance now or hereafter in
       effect.

9.     UTILITIES AND FEES.  It is Lessor's policy that utilities and services be
       furnished as set forth in Exhibit D hereto.  Lessor's failure to furnish
       any of such items shall not result in any liability to Lessor, Lessee
       shall not be entitled to any abatement or reduction of rent by reason of
       such failure, and no eviction of Lessee shall result from such failure.
       If Lessee uses more water or electrical power than is considered
       reasonable or normal by Lessor, Lessor may at its option require Lessee
       to pay, as additional rent, the cost, as fairly determined by Lessor,
       incurred by such extraordinary usage.  In addition, Lessor may install
       separate meter(s) for the Premises, at Lessee's sole expense, and Lessee
       thereafter shall pay all charges so metered.  Alternatively, Lessee may
       utilize a portion of the Lessee Improvement Allowance to pay for the cost
       of the installation of such separate meter(s).

10.    ADDITIONAL RENT AND MONTHLY OPERATING EXPENSE ADJUSTMENTS.  For each
       calendar year during this Lease, or portion thereof, Lessee shall pay as
       Additional Rent its pro rata share of the amount by which Operating
       Expenses for each year exceed $4.30 per square foot.  Lessor shall
       estimate, from time to time, Lessee's payment amount.  This estimated
       amount shall be divided into equal monthly installments, one payable with
       each installment of the Monthly Minimum Rent.  As soon as practical
       following each calendar year, Lessor shall prepare


                                     Page 2

<PAGE>

       an accounting of actual Operating Expenses incurred during the prior
       calendar year and such accounting shall reflect Lessee's Percentage.  If
       the Additional Rent paid by Lessee under this Section 10 during the
       preceding calendar year was less than the actual amount of Lessee's
       Percentage of Operating Expenses, Lessor shall notify Lessee and Lessee
       shall pay such amount to Lessor within fifteen (15) days of receipt of
       such notice.  Lessee shall have fifteen (15) days from receipt of such
       notice to contest the amount due; failure to so notify Lessor shall
       represent final determination of Lessee's share of Operating Expenses.
       If Lessee's payments were greater than the actual amount due, then such
       overpayment shall be credited to Lessor to all present rent next due
       under this Section 10.

       For the purposes of this Paragraph 10, "Operating Expenses" shall
       include, but not be limited to:

       a)     Real Estate taxes and assessments, all costs of management,
              operation and maintenance of the Premises, the building and the
              Land, including without limitation the following:  wages and
              salaries of employees; janitorial, cleaning, maintenance, and
              other services; electricity, water, waste disposal and other
              utilities; heating, ventilating and air conditioning; materials
              and supplies; painting, repairs and other maintenance; insurance;
              all real and personal property taxes, assessments, and charges
              levied upon or with respect to the Land, the Building or Lessor's
              interest in the same; and depreciation on personal property,
              Management fees; expenses incurred to operate an on site
              management office; association dues directly attributable to the
              management of the property.  Expenses shall not include
              depreciation on the Building; costs of tenants' improvements; real
              estate brokers' commissions; or capital items except that Expenses
              shall include the cost of any capital improvements made after
              completion of the Building as a labor-saving device or to effect
              other economies in the operation or maintenance of the building or
              made after the date of this Lease that are required under any
              governmental law or regulation, such costs to be amortized over
              such reasonable period as Lessor shall determine, together with
              interest at a rate equal to the rate of interest publicly
              announced from time to time by Seattle First National Bank of
              Washington, Seattle, Washington, as its "prime interest rate" plus
              two percent (2%) per annum or such higher rate as may be paid by
              Lessor on funds borrowed for the purpose of constructing such
              capital improvements.

       Even after this Lease has expired or been terminated, when final
       determination is made of Lessee's Percentage of Operating Expenses for
       the year in which this Lease expires or terminates, Lessee shall
       immediately pay any shortfall due.  Conversely, any overpayment made
       shall be rebated by Lessor to Lessee, unless Lessee at that time is
       indebted to Lessor.

11.    LESSOR'S RESERVATIONS.  Lessor reserves the right without liability to
       Lessee:  (a) to inspect the Premises, to show them to prospective
       Lessees, and if they are vacated, to prepare them for reoccupancy; (b) to
       retain at all times and to use in appropriate instances keys to doors
       within and into the Premises; (c) to make repairs, alterations, additions
       or improvements, whether structural or otherwise, in or about the
       building, and for such purposes to enter upon the Premises and during the
       continuance of any work, to close common areas and to interrupt or
       temporarily suspend building services and facilities, all without
       affecting any of Lessee's obligations hereunder, so long as the Premises
       are reasonably accessible; and (d) generally to perform any act relating
       to the safety, protection and preservation of the Premises or building.

12.    POSSESSION.  If Lessor does not deliver possession of the Premises at the
       Commencement Date of the term of this Lease, Lessee may give Lessor
       written notice of its intention to cancel


                                     Page 3

<PAGE>

       this Lease if possession is not delivered within ninety (90) days after
       receipt of such notice by Lessor.  Lessor shall not be liable for any
       damages caused by failure to deliver possession of the Premises and
       Lessee shall not be liable for any rent until such time as Lessor
       delivers possession.  A delay of possession shall not extend the
       termination date.  If Lessor offers possession of the Premises or any
       portion thereof prior to the Commencement Date of the term of this
       Lease, and if Lessee accepts such early possession, then both parties
       shall be bound by all of the covenants and terms contained herein during
       such period of early possession including the payment of rent which
       shall be pro-rated accordingly and for the number of days of such early
       possession.

13.    ASSIGNMENT AND SUBLETTING.  Lessee shall not either voluntarily or by
       operation of law assign, transfer, convey or encumber this Lease or any
       interest under it, or sublet to occupy or use the Premises without
       Lessor's prior written consent.  Lessor reserves the right to recapture
       the Premises or applicable portion thereof in lieu of giving its consent
       by notice given to Lessee within twenty (20) days after receipt of
       Lessee's written request for assignment or subletting.  Such recapture
       shall terminate this Lease as to the applicable space effective on the
       prospective date of assignment or subletting, which shall be the last day
       of a calendar month and not earlier than sixty (60) days after receipt of
       Lessee's request hereunder.  In the event that Lessor shall not elect to
       recapture and shall thereafter give its consent, Lessee shall pay Lessor
       a reasonable fee, not to exceed One Thousand and No/100 Dollars
       ($1,000.00) to reimburse Lessor for processing costs incurred in
       connection with such consent.  Lessor's consent shall not release or
       discharge Lessee from future liability under this Lease and shall not
       waive Lessor's right to consent to any future assignment or sublease.
       Any assignment or subletting without Lessor's consent shall be void and
       shall, at Lessor's option, constitute a default under this Lease.  A
       transfer by the present majority shareholders of ownership or control of
       a majority of the voting stock of a corporate Lessee shall be deemed an
       assignment.

14.    ALTERATIONS.  After obtaining the prior written consent of Lessor, Lessee
       may make minor alterations, additions and improvements in said Premises
       (so long as such alterations, additions or improvements are not visible
       from the exterior of the Premises) at its sole cost and expense.  Lessee
       agrees to save Lessor harmless from any damage, loss, or expense arising
       therefrom and to comply with all laws, ordinances, rules and regulations.
       Upon termination of this Lease, all alterations, additions and
       improvements made in, to or on the Premises (including without limitation
       all electrical, lighting, plumbing, heating, air conditioning, and
       communications equipment and systems, doors, windows, partitions,
       drapery, carpeting, shelving, counters, and physically attached fixtures
       unless excluded by written agreement annexed hereto), shall remain upon
       and be surrendered as a part of the Premises; provided however, upon
       Lessor's request, Lessee shall promptly remove those additions,
       alterations, or improvements as may be specified by Lessor, and repair
       and restore the Premises to its original condition at Lessee's sole cost
       and expense.

15.    LIENS.  Lessee shall keep the Premises free from any liens arising out of
       any work performed, materials furnished, equipment supplied, or
       obligations incurred by or on behalf of Lessee.  No work performed,
       material furnished, equipment supplied or obligations incurred by or on
       behalf of Lessee shall be deemed to be for the immediate use and benefit
       of Lessor so that no mechanic's lien or other lien shall be allowed
       against Lessor's estate in the Premises.  Lessee shall provide, at
       Lessee's own cost, a waiver of lien signed by any party (including the
       Lessee) who commences to perform work, furnish materials, or supply
       equipment to the Premises.  Lessor does not authorize or consent to the
       performance of any work, furnishing of material or supply of equipment
       incurred by or on behalf of Lessee prior to Lessee providing Lessor with
       the signed


                                     Page 4

<PAGE>

       waiver of lien referred to above.  Lessor may require, at Lessee's sole
       cost and expense, a lien release and completion bond in an amount equal
       to either the actual contract price or one and one-half times the
       estimated cost of any improvements, additions or alterations in the
       Premises which Lessee desires to make, to insure Lessor against any
       liability for lien and to insure completion of the work.

16.    SIGNS.  All signs or symbols placed by Lessee in the windows and doors of
       the Premises, or upon any exterior part of the building, shall be subject
       to Lessor's prior written approval.  Prior to termination of this Lease,
       Lessee will remove all signs placed by it upon the Premises, and will
       repair any damages caused by such removal.

17.    INSURANCE.

       A.     Lessee shall pay for and maintain, during the entire Lease Term,
              the following policies of insurance:

                            (i)    Commercial general liability insurance,
                     including products, completed operations coverage and auto
                     liability insurance covering Lessee's operations and the
                     Premises including but not limited to coverage for personal
                     injuries with limits of not less than $1,000,000 combined
                     single limit for death, personal injury, and property
                     damage, per occurrence, including Lessor as an additional
                     insured.  Such policies shall be endorsed to provide
                     contractual liability insurance covering all liability
                     assumed by Lessee under the provisions of this Lease and a
                     copy of said endorsement will be delivered to Lessor prior
                     to commencement of the Term.

                            (ii)   Special cause of loss or "all risk" perils
                     and sprinkler leakage property insurance upon all
                     alterations on the Premises and upon Lessee's property,
                     including but not limited to Fire and Extended Coverage,
                     Vandalism and Malicious Mischief, in the amount of one
                     hundred percent (100%) full replacement cost, including
                     Lessor as an additional insured, as its interests may
                     appear, with a loss payable clause in favor of Lessor to
                     the extent of Lessor's interest in property damaged, except
                     to the extent proceeds are required to be paid to holders
                     of mortgages or trust deeds.

       B.     Each policy provided by Lessee shall expressly provide that it
              shall not be subject to cancellation or material change without at
              least thirty (30) days prior written notice to Lessor.  Lessee
              shall furnish Lessor, prior to commencement of the Term, with
              insurance certificates and, upon request, copies of such policies
              required to be maintained hereunder.

18.    INDEMNITY AGAINST LIABILITY FOR LOSS OR DAMAGE BY LESSEE.

       A.     Lessee assumes all liability for and shall indemnify, hold
              harmless and defend Lessor from and against all loss, damage or
              expense which the Lessor may sustain or incur, and against any and
              all claims, demands, suits and actions whatsoever, including
              expense of investigation and litigation, on account of injury to
              or death of persons, including without limitation employees of
              Lessor, employees of Lessee or its affiliated companies or on
              account of damage to or destruction of property, including without
              limitation property


                                     Page 5

<PAGE>

              owned by and property in the care, custody or control of Lessor
              during the Term, due to or arising in any manner from:

                                   (i)    The acts or negligence of Lessee or
                            any contractor, subcontractor, or agent of Lessee or
                            their respective employees;

                                   (ii)   The condition, use or operation of the
                            Premises and/or materials or substances used by
                            Lessee or any of its contractors, subcontractors or
                            agents of Lessee or by their respective employees,
                            regardless of whether or not furnished by Lessor
                            under this Lease or otherwise;

                                   (iii)  Any damage or injury to persons or
                            property arising out of Lessee's breach or this
                            Lease, including, but not limited to, obligations of
                            Lessee under Section 8, Maintenance and Repairs.

       B.     Lessor shall have no liability to Lessee as a result of loss or
              damage to Lessee's property or for death or bodily injury caused
              by the acts or omissions of other tenants in the project or by
              third parties (including criminal acts).

       C.     It is mutually understood and agreed that the assumption of
              liabilities and indemnification provided for in this Section 18
              shall survive any termination of this Lease.

       D.     Notwithstanding the preceding provisions of this Section 18,
              Lessor and Lessee each herewith and hereby release and relieve the
              other and waive its entire right of recovery against the other for
              loss or damage arising out of or incident to perils insured
              against, whether due to the negligence of either party, their
              agents, employees, contractors, invitees or otherwise.

19.    DAMAGE OR DESTRUCTION. If the Premises or the building in which the
       Premises are located shall be damaged or destroyed by fire or other
       casualty, Lessor shall have the Option either (a) to repair or rebuild
       within one hundred twenty (120) days, or (b) not to repair  or rebuild,
       and to cancel this Lease on thirty (30) days notice. If Lessor fails to
       give Lessee written notice of its election within thirty (30) days from
       the date of damage, or if the restoration of the Premises cannot be
       completed within one hundred twenty (120) days from date of notice,
       Lessee may cancel this Lease at its option on thirty (30) days notice.
       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 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 monthly rent 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 or if more than twenty-five percent (25%) of the
       rentable square footage of the Premises shall be so taken, then


                                     Page 6

<PAGE>

       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. If any part of the building other than the Premises shall be
       so taken so as to render in Lessor's opinion the termination of this
       Lease beneficial to the remaining portion of the building, Lessor shall
       have the right within sixty (60) days of said taking to terminate this
       Lease upon thirty (30) days written notice to Lessee. In the event of any
       taking, whether whole or partial, Lessor shall be entitled to all awards,
       settlements, or compensation which may be given for the land and
       buildings. Lessee shall have no claim against Lessor for the value of any
       unexpired term of this Lease.

21.    INSOLVENCY. If Lessee shall be declared insolvent or bankrupt, or if
       Lessee's leasehold interest herein shall be levied upon or seized under
       writ of any court of law, or if a trustee, receiver or assignee be
       appointed for the property of Lessee, whether under operation of State or
       Federal statutes, then Lessor may, at its option, immediately, without
       notice (notice being expressly waived), terminate this Lease and take
       possession of said Premises, without, however, terminating Lessee's
       obligations under this Lease.

22.    DEFAULT AND RE-ENTRY. If Lessee fails to keep or perform any of the
       covenants and agreements herein contained, then the same shall constitute
       a breach hereof, and if Lessee has not remedied such breach within three
       (3) days after written notice thereof from Lessor if the breach is
       non-payment of rent or other charges, or within ten (10) days after
       written notice thereof from Lessor in the event of the breach of any
       other covenant, then Lessor may, at its option, without further notice or
       demand:

       (a)    Cure such breach for the account and at the expense of Lessee and
              such expense shall be deemed additional rent due on the first of
              the following month; or

       (b)    Re-enter the Premises, remove all persons therefrom, take
              possession of the Premises and remove all personal property
              therein at Lessee's risk and expense and (1) terminate this Lease,
              or (2) without terminating the Lease or in any way affecting the
              rights and remedies of Lessor or the obligations of Lessee, re-let
              the whole or any part of the Premises as agent for Lessee, upon
              such terms and conditions as Lessor may deem advisable. In either
              event, any moneys received from Lessee and any deposit or other
              amounts held by Lessor may first be applied by Lessor to any
              damages suffered by Lessor as a result of such default, including
              without limitation, costs and expenses incurred on re-entry and
              re-letting, any unamortized tenant improvements and commissions,
              cleaning, necessary repairs, restoration and alteration, and any
              commissions incurred on re-letting, and the balance of such
              amounts may be applied toward payment of other sums due to Lessor
              hereunder. In the event the Premises are re-let for Lessee's
              account, Lessee shall pay to Lessor monthly any deficiency;
              however, Lessor shall not be required to pay any excess to Lessee.
              Upon termination of this Lease or of Lessee's right to possession,
              Lessor has the right to recover from Lessee: (1) The worth of the
              unpaid rent that had been earned at the time of such termination;
              (2) The worth of the amount of the unpaid rent that would have
              been earned after the date of such termination; and (3) Any other
              amount, including court, attorney and collection costs, necessary
              to compensate Lessor. "The Worth," as used in Section (1) of this
              paragraph 22(b) is to be allowing interest at 18% per year.  "The
              Worth" as used for Section2) of this paragraph 22(b) is to be
              computed by discounting the amount at the discount rate of the
              Federal Reserve Bank of San Francisco at the time of termination.
              The above


                                     Page 7

<PAGE>

              remedies of Lessor are cumulative and in addition to any other
              remedies now or hereafter allowed by law or elsewhere provided
              for in this Lease.

23.    REMOVAL OF PROPERTY. Any property of Lessee removed by Lessor in
       accordance with Section 22 above may be stored by Lessor or may be
       deposited on any area adjacent to the building at the sole risk and
       expense of Lessee and without any further responsibility of Lessor, and
       Lessor may at its sole discretion without removing said property or after
       removing said property, without obligation to do so and without notice to
       Lessee, sell or dispose of the same at public or private sale for the
       account of Lessee, in which event the proceeds therefrom may be applied
       by Lessor upon any indebtedness due from Lessee to Lessor. Lessee waives
       all claims for damages that may be caused by Lessor re-entering the
       Premises and removing or disposing of said property as herein provided.

24.    COSTS AND ATTORNEYS' FEES. In the event either party shall commence legal
       action to enforce any provision of this Lease, the court shall award to
       the prevailing party all reasonable attorneys' fees and all costs

       action relating to this Lease shall be brought in the County in which the
       Premises are located or, at Lessor's election, in King County,
       Washington.

25.    SUBROGATION WAIVER. Lessor and Lessee each herewith and hereby release
       and relieve the other and waive its entire right of recovery against the
       other for loss or damage arising out of or incident to the perils of
       fire, explosion or any other perils described in the "all risk" insurance
       endorsement approved for use in the state in which the Premises are
       situated which occurs in, on or about the Premises, whether due to the
       negligence of either party, their agents, employees or otherwise.

26.    HOLDING OVER. If Lessee, with the express consent of Lessor, shall hold
       over after the expiration of the term of this Lease, Lessee shall remain
       bound by all the covenants and agreements herein, except that (a) the
       tenancy shall be from month-to-month and (b) the monthly rent to be paid
       by Lessee shall be determined by multiplying the monthly rent in effect
       preceding such expiration times 150%.

27.    SUBORDINATION AND ATTORNMENT; MORTGAGEE PROTECTION.

       A.     SUBORDINATION NOTICE TO MORTGAGEE. At the request of Lessor,
              Lessee shall promptly execute, acknowledge and deliver, all
              instruments which may be required to subordinate this Lease to any
              existing or future mortgages, deeds of trust and/or other security
              documents on or encumbering the Premises or on the leasehold
              interest held by Lessor, and to any extensions, renewals, or
              replacements thereof, provided that the mortgagee or beneficiary,
              as the case may be, shall agree to recognize this Lease in the
              event of foreclosure if Lessee is not in default at such time.

       B.     LESSEE'S CERTIFICATE.  Lessee shall at any time and from time to
              time upon not less than three (3) days prior written notice from
              Lessor execute, acknowledge and deliver to Lessor a statement in
              writing (a) certifying that this Lease is unmodified and in full
              force and effect (or, if modified, stating the nature of such
              modification and certifying that this Lease as so modified is in
              full force and effect), and the date to which the rental and other
              charges are paid in advance, if any; and (b) acknowledging that
              there are not, to Lessee's knowledge, any uncured defaults on the
              part of the Lessor or Lessee hereunder,


                                     Page 8

<PAGE>

              or specifying such defaults if any are claimed; and (c) setting
              forth the date of commencement of rents and expiration of the
              Lease Term hereof.  Any such statement may be relied upon by any
              prospective purchaser or encumbrancer of all or any portion of
              the Premises of which the Premises are a part.

       C.     MORTGAGEE PROTECTION CLAUSE. Lessee agrees to notify any mortgagee
              and/or trust deed holders, by registered mail, with a copy of any
              notice of default served upon the Lessor, provided that prior to
              such notice Lessee has been notified in writing (by way of Notice
              of Assignment of Rents and Lease, or otherwise) of the addresses
              of such mortgagees and/or trust deed holders. Lessee further
              agrees that if Lessor shall have failed to cure such default, then
              the mortgagees and/or trust deed holders have thirty (30) days
              within which to cure such default or if such default cannot be
              cured within that time, then such additional times as may be
              necessary if within such thirty (30) days any mortgagee and/or
              trust deed holder has commenced and is diligently pursuing the
              remedies necessary to cure such default (including but not limited
              to commencement of foreclosure proceedings if necessary to affect
              such cure), in which event this Lease shall not be terminated if
              such remedies are being so diligently pursued.

28.    SURRENDER OF POSSESSION. Lessee shall, prior to the termination of this
       Lease or of Lessee's right to possession, remove from the Premises all
       personal property which Lessee is entitled to remove and those
       alterations, additions, improvements or signs which may be required by
       Lessor to be removed, pursuant to Sections 12 and 14 above, and shall
       repair or pay for all damage to the Premises caused by such removal. All
       such property remaining and every interest of Lessee in the same shall be
       conclusively presumed to have been conveyed by Lessee to Lessor under
       this Lease as a bill of sale, without compensation, allowance or credit
       to Lessee. Lessee shall upon termination of this Lease or of Lessee's
       right of possession, deliver all keys to Lessor and peacefully quit and
       surrender the Premises without notice, neat and clean, and in as good
       condition as when Lessee took possession, except for reasonable wear and
       tear as determined by Lessor.

29.    LATE PAYMENT AND INTEREST. If any amount due from Lessee is not received
       in the office of Lessor on or before the third (3rd) day following the
       date upon which such amount is due and payable, a late charge of five
       percent (5%) of said amount shall become immediately due and payable,
       which late charge Lessor and Lessee agree represents a fair and
       reasonable estimate of the processing and accounting costs that Lessor
       will incur by reason of such late payment.  All past due amounts owing to
       Lessor under this Lease, including rent, shall be assessed interest at an
       annual percentage rate of eighteen percent (18%) from the date due or
       date of invoice, whichever is earlier, until paid.

30.    NOTICE. Any notice required to be given by either party to the other
       pursuant to the provisions of this Lease or any law, present or future,
       shall be in writing, and shall be deemed to have been dully given or sent
       if either delivered personally or deposited in the United States Mail,
       postage prepaid, registered or certified, addressed to the Lessor at the
       address specified for the payment of rent under paragraph 3 of this Lease
       or to Lessee at the Premises or to such other address as either party may
       designate to the other in writing from time to time:

31.    NO WAIVER OR COVENANTS. Time is of the essence of this Lease. Any waiver
       by either party of any breach hereof by the other shall not be considered
       a waiver of any future similar or other breach.

32.    BINDING ON HEIRS, SUCCESSORS AND ASSIGNS.  The covenants and agreements

       provided.

33.    LESSOR'S ASSIGNMENT.  Lessor shall have the full right to assign this
       Lease, without any notice to Lessee, thereby relieving Lessor from all
       and any liabilities; provided however, that the assignee assumes all
       Lessor's responsibilities as set forth in this Lease.

34.    ENVIRONMENTAL, EMISSIONS; STORAGE, USE AND DISPOSAL OF WASTE:

       a.     EMISSIONS. Lessee shall not (i) discharge, emit or permit to be
              discharged or emitted, any liquid, solid or gaseous matter, or any
              combination thereof, into the atmosphere, the ground or any body
              of water, which does or may pollute or contaminate the same, or
              does or may adversely affect the health or safety of persons, or
              the use or enjoyment of the Premises; nor (ii) transmit, receive
              or permit to be transmitted or received, any electromagnetic,

       b.     STORAGE. If, with or without violation of this Lease, Lessee
              possesses at the Premises any matter described in Section A above
              or any Hazardous Substances (as defined below), Lessee shall store
              the same in appropriate leak proof containers and/or areas which
              comply with all laws and all prudent practices.

       c.     DISPOSAL OF WASTE.  Lessee shall not keep any trash, garbage,
              waste or other refuse on the Premises except in sanitary
              containers and shall regularly and frequently remove same from the
              Premises. Lessee shall keep all such containers in a clean and
              sanitary condition. Lessee shall properly dispose of all sanitary
              sewage and shall not use the sewage system for the disposal of
              anything except sanitary sewage, nor in excess of capacity.
              Lessee shall not cause any obstruction in the sewage disposal
              system.

       d.     COMPLIANCE OF LAW. Notwithstanding any other provision in the
              Lease to the contrary, Lessee shall comply with all Laws in

              particular, laws relating to the storage, use and disposal of
              Hazardous Substances (as defined below).

              or expense, including, without limitation, attorneys fees and
              costs, at trial and/or on appeal and review, arising out of or in
              connection with its failure to observe or comply with the
              provisions of this Section. This indemnity shall survive the
              expiration or earlier termination of the term of the Lease or the
              termination of Lessee's right of possession and be fully
              enforceable thereafter.

              herein. This indemnity shall include (i) claims of third parties,
              including governmental agencies, for damages, fines, penalties,
              response costs, monitoring costs, injunctive or other relief;

              at, before and after any administrational proceeding, trial,

              earlier termination of the term of the Lease or the termination of
              Lessee's right of possession and shall remain fully enforceable
              thereafter.

              Lessor. In the event of any accident, spill or other incident
              involving Hazardous Substances, Lessee shall immediately report
              the same to Lessor and supply Lessor with all information and
              reports with respect to the same. All information described herein
              shall be provided to Lessor regardless of any claim by Lessee that
              it is confidential or privileged.

       35.    ENTIRE AGREEMENT.  It is expressly understood and agreed by Lessor
              and Lessee that there are no promises, agreements, conditions,
              understandings, inducements, warranties, or representations, oral
              or written, express or implied, between them, other than as herein

                        STANDARDS FOR UTILITIES AND SERVICES

To Lease made on this 20 day of March, 1996, between Commercial Real Estate
Company, L.L.C., a Washington limited liability company (the "Lessor") and
CheckFree Corporation, an Ohio corporation, (the "Lessee").

       The following Standards for Utilities and Services are in effect. Lessor
reserves the right to adopt nondiscriminatory modifications and additions
hereto.

1.     Non-attended automatic elevator facilities.

2.     Monday through Friday, except holidays, from 8 a.m. to 6 p.m (and other
times for the sum of $20.00 per hour), ventilate the Premises and furnish air
conditioning or heating on such days and hours, when in the reasonable judgment
of Lessor it may be required for the comfortable occupancy of the Premises.
Lessee agrees to cooperate fully at all times with Lessor, and to abide by all
reasonable regulations and requirements which Lessor may prescribe for the
proper function and protection of said air conditioning system. Lessee agrees
not to connect any apparatus, device, conduit or pipe to the building chilled
and hot water air conditioning supply lines. Lessee further agrees that neither
Lessee nor its, employees, agents, visitors, licensees or contractors shall at
any time enter mechanical installations or facilities of the Building or adjust,
tamper with, touch or otherwise in any manner affect said installations or
facilities. The cost of maintenance and service calls to adjust and regulate the
air conditioning system shall be charged to Lessee if the need for maintenance
work results from either Lessee's adjustment of room thermostats or Lessee's
failure to comply with its obligations under this section. Such work shall be
charged at hourly rates equal to then-current journeymen's wages to air
conditioning mechanics.

3.     During the usual business hours on business days, electric current as
required by the building standard office lighting and fractional horsepower
office business machines in an amount not to exceed 3.5 watts per square foot.
Lessee agrees, should its electrical installation or electrical consumption be
in excess of the aforesaid quantity or extend beyond normal business hours, to
reimburse Lessor monthly for the measured consumption at the average cost per
kilowatt hour charged to the building during the period. If a separate meter is
not installed at Lessee's cost, such excess costs will be established by an
estimate agreed upon by Lessor and Lessee, and if the parties fail to agree, as
established by an independent licensed engineer. Lessee agrees not to use any
apparatus or device in, or upon, or about the Premises which may in any way
increase the amount of such services usually furnished or supplied to said
Premises, and Lessee further agrees not to connect any apparatus or devise with
wires, conduits or pipes, or the other means by which such services are
supplied, for the purpose of using additional or unusual amounts of such
services without the prior written consent of Lessor. Should Lessee use the same
to excess, the refusal on the part of Lessee to pay upon demand of Lessor the
amount established by Lessor for such excess charge shall constitute a breach of
the obligation to pay rent under this Lease and shall entitle Lessor to the
rights therein granted for such breach. At all times Lessee's use of electric
current shall never exceed the capacity of the feeders to the building or the
risers or wiring installation and Lessee shall not install or use or permit the
installation or use of any unusually high weight or high electrical consumption
computer or electronic data processing equipment in the Premises without the
prior written consent of Lessor.

4.     Provide janitor service to the Premises, provided the same are used
exclusively as offices, and are kept reasonably in order by Lessee, and if to be
kept clean by Lessee, no one other than persons approved


                                       Page 19

<PAGE>

by Lessor shall be permitted to enter the Premises for such purposes. If the
Premises are not used exclusively as offices, they shall be kept clean and in
order by Lessee, at Lessee's expense, and to the satisfaction of Lessor, and
by persons approved by Lessor. Lessee shall pay to Lessor the cost of removal
of any of Lessee's refuse and rubbish to the extent that the same exceeds the
refuse and rubbish usually attendant upon the use of the Premises as offices.

       Lessor reserves the right to stop service of the elevator, plumbing,
ventilation, air conditioning and electric systems, when necessary, by reason of
accident or emergency or for repairs, alterations or improvements, in the
judgment of Lessor desirable or necessary to be made, until said repairs,
alterations or improvements, shall have been completed, and shall further have
no responsibility or liability for failure to supply elevator facilities,
plumbing, ventilation, air conditioning or electric service. It is expressly
understood and agreed that any covenants, express or implied, for Lessor to
furnish any service for the benefit of Lessee shall not be deemed breached if
Lessor is unable to furnish or perform the same by virtue of a strike or labor
trouble or any other cause whatsoever beyond Lessor's reasonable control.

5.     Lessee shall not use or install in the Premises any hear generating
equipment, except as specifically authorized herein, or installed pursuant to
the Work Letter Agreement, without Lessor's prior written consent. The inclusion
of this restriction is to ensure that the HVAC system is adequate to service the
Building and the various uses of tenants that occupy the Building.

       and conditions under which Lessor will lease the space. Lessee shall
       respond within five (5) business days of written notification by Lessor
       if Lessee wishes to lease the space. If Lessee shall not respond within
       five (5) business days, Lessee shall be deemed to have passed on the
       offer to lease the space. Should Lessee accept such offer to lease,
       Lessee shall enter into a Lease for the space.

       Lessee Improvement Allowance shall be used by Lessee to recarpet,
       repaint and/or remodel the Premises. Such Lessee Improvements will be
       based upon a space plan mutually acceptable to Lessor and Lessee.

       Improvement Allowance will be at Lessee's sole cost and expense. All
       improvements to the Premises shall conform to the provisions of

       Improvement Allowance, Lessor shall be responsible for the cost of
       demolishing the Premises as provided in the Construction Drawings and
       providing American with Disabilities Act improvements to the Premises
       as reasonably required by the City of Beaverton, Oregon.

       Thousand Seven Hundred Fifty and No/100 Dollars ($56,750.00), complete
       the construction of the improvements to the Premises as described and
       delineated in a space plan mutually acceptable to Lessor and Lessee, as
       provided by Lessee.  Lessee Improvement Costs to the Premises in excess
       of this Lessee Improvement Allowance of $56,750.00 shall be Lessee's
       responsibility.  Lessor shall cause to be prepared final drawings
       ("Construction Drawings") for the Lessee Improvements that are consistent
       with and are logical evolutions of the space plans.  As soon as such
       Construction Drawings are completed, Lessor shall deliver the same to
       Lessee for approval.  Lessee shall promptly review and approve the
       Construction Drawings within two (2) days after the date of receipt
       thereof and shall initial two (2) copies of the Construction Drawings as
       indication of its approval thereof.  Lessee's approval of the
       Construction Drawings shall constitute Lessor's authorization to complete
       the Lease Improvements in accordance with such Construction Drawings.  If
       Lessee shall request any change in the Construction Drawings, Lessor
       shall promptly notify Lessee in writing of the additional costs of
       construction of the Lessee Improvements required by such change, and
       Lessee shall accompany its approval of the Construction Drawings with a
       check made payable to Lessor in the amount of the authorized excess
       costs.  If Lessor does not receive written authorization, and Lessee's
       check for any additional costs incurred as a result of Lessee's request
       for changes in the Construction Drawings, within three (3) business days
       after the date of receipt of notice from Lessor of the additional cost of
       construction required by such change, then Lessor may, at its option,
       terminate the Lease by giving written notice of such termination to
       Lessee.  If Lessor does not elect to terminate the Lease, Lessor shall
       not be obligated to commence work on the Premises, and Lessee shall be
       charged withany delay in completion of the Premises.

2.     Lessee is responsible for the suitability of the design and function of
       the Lessee Improvements for Lessee's needs and business.  Lessee shall

       Premises by Lessee, and the cost of such Personal Property shall be paid
       by Lessee.  Lessee shall conform to the Building's wiring standards in
       installing any telephone and computer equipment and shall be subject to
       any and all rules of the site during construction of the Lessee
       Improvements.

3.     If Lessee shall request any change, addition or alteration in the plans,
       the Building standards or the approved Construction Drawings, Lessor
       shall promptly give Lessee a written estimate of (a) the cost of
       engineering and design services to prepare a change order ("Change
       Order") in accordance with such request, (b) the cost of the work to be
       performed pursuant to such Change Order, and (c) the time delay expected
       because of such requested Change Order.  Within two (2) business days
       following Lessee's receipt of the foregoing written estimate, Lessee
       shall notify Lessor in writing whether it approves such written estimate.
       If Lessee approves such written estimate, Lessee shall accompany such
       approval with a good check made payable to Lessor in the


                                       Page 23

<PAGE>

       amount of the estimated cost of preparing the Change Order and
       performing the work thereof, and the foregoing shall constitute
       Lessor's authorization to proceed.  If such written authorization and
       check are not received by Lessor within such two (2) business days
       period, Lessor shall not be obligated to prepare the Change Order or
       perform any work in connection therewith.  Upon completion of the work
       of the Change Order and submission of the final cost thereof by Lessor
       to Lessee, Lessee shall promptly pay any such additional amounts due
       Lessor.

4.     If the completion of the Lessee Improvements in the Premises is delayed
       (i) at the request of Lessee, (ii) by Lessee's failure to comply with the
       foregoing provisions, (iii) by changes in the work requested (whether or
       not Lessee authorizes Lessor to proceed therewith) or ordered by Lessee
       or by extra work ordered by Lessee, or (iv) because Lessee chooses to
       have additional work performed by Lessor (each, a "Lease Delay"), then
       Lessee shall be responsible for all costs and expenses occasioned by such
       delays, including, without limitation, any costs and expenses
       attributable to increases in labor or materials, and there shall be no
       delay in the commencement of Lessee's obligation to pay rent if the
       completion of the Lessee Improvements is delayed as a result of the
       foregoing.

5.     Lessee may, with Lessor's written consent, enter the Premises prior to
       the Commencement Date solely for the purpose of installing Lessee's
       Personal Property and equipment as long as such entry does not interfere
       with the orderly construction and completion of the Premises.  Lessee
       shall notify Lessor of its desired time(s) of entry and shall submit for
       Lessor's approval the scope of the work to be performed and the name(s)
       of the contractor(s) who will perform such work.  Lessee hereby
       indemnifies and agrees to protect, defend and hold Lessor, any mortgagee,
       ground lessor or beneficiary of a mortgage, ground lease or deed of trust
       related to the Premises or the Building harmless from and against any and

       for worker's compensation) for any nature whatsoever, together with
       reasonable attorney fees for counsel of Lessor's choice, arising out of
       or in connection with the installation of Lessee's Personal Property or
       equipment (including, but not limited to, claims for breach of warranty,
       personal injury or property damage).
