and Mask Works listed on Schedules A, B, C, and D hereto), and including without
limitation all proceeds thereof (such as, by way of example but not by way of
limitation, license royalties and proceeds of infringement suits), the right to
sue for past, present and future infringements, all rights corresponding thereto
throughout the world and all re-issues, divisions continuations, renewals,

interest granted hereby are in addition to those set forth in the Loan Agreement
and the other Loan Documents, and those which are now or hereafter available to

Lenders of any one or more of the rights, powers or remedies provided for in
this Intellectual Property Security Agreement, the Loan Agreement or any of the
other Loan Documents, or now or hereafter existing at law or in equity, shall
not preclude the simultaneous or later exercise by any person, including Agent
and Lenders, of any or all other rights, powers or remedies.

                           SECOND AMENDMENT TO LEASE

     This SECOND AMENDMENT TO LEASE (this "Second Amendment") is made and
entered into as of the 6th day of August, 2000, by and between BELLEVUE HINES

SOFTWARE CORPORATION, a Washington corporation ("Tenant") with reference to that
certain Lease (as defined below) covering certain premises located in the One

                                   RECITALS

     A.   Landlord and Tenant are parties to that certain Office Building Lease
dated as of June 6, 2000, as amended by that First Amendment to Lease dated June
20, 2000, (the "Lease") pursuant to which Tenant leased certain space in the

meanings given in the Lease.

     B.   Tenant now wishes to add additional space to the Premises and to
modify the Initial Term for that portion of the Premises located in the East

document such modifications.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby mutually acknowledged, the parties hereto agree
as follows:

     1.   Expansion of Premises; Restated Basic Lease Information Sheet. Tenant
hereby leases from Landlord and Landlord hereby leases to Tenant all of Floors

Hundred Fifty-six (78,256) square feet of Useable Area. The Additional Premises
shall be added to the Premises so that from and after the date hereof, the term
"Premises" shall include the Premises (as described in the Lease) and the

subject to all of the terms and conditions of the Lease applicable to the
Premises. The Basic Lease Information Sheet for the Lease is hereby restated and
replaced in its entirety by Exhibit A attached hereto and incorporated herein by
                            ---------
this reference, which reflects the modifications set forth herein.

</TABLE>

     Base Rent for the East Building shall be as indicated in Item 11 of the
                                                              -------
Basic Lease Information Sheet attached hereto as Exhibit A.
                                                 ---------

     4.   Term. The following provisions shall fully replace and supercede
Section 2.1(a) of the Lease:
-------------

     (a)  Except as otherwise provided herein, the term "Term Commencement Date"
shall mean the later of (i) the Rent Commencement Date for the final floor of
the Premises pursuant to Section 2.6(a) below, or (ii) the Scheduled
                         --------------
Commencement Date, as stated in the Basic Lease Information Sheet as Item 9.  If
                                                                     ------
Tenant commences business on all floors of the Premises prior to the Scheduled
Commencement Date, the date such business begins shall be the Term Commencement
Date.  The "Initial Term" of this Lease with respect to each Building shall mean
the number of years and/or months set forth as the "Initial Term" in the Basic
Lease Information Sheet as Item 10 for such Building, commencing on the first
                           -------
day of the calendar month following the Term Commencement Date (or on the Term
Commencement Date if it is the first day of a calendar month) through and
including the Expiration Date.  "Expiration Date" with respect to each Building
shall mean the last day of the Term or such earlier date upon which this Lease
is terminated pursuant to the terms hereof.  The "Term" of this Lease with
respect to each Building shall mean the Initial Term and the Extension Term(s)
(as defined in Section 2.1(b)), if any.  For all purposes hereunder, the term
               --------------
"Lease Year" shall mean a twelve (12) month period starting on the Term
Commencement Date or any anniversary thereof, the first Lease Year shall begin
on the Term Commencement Date and the final Lease Year may contain more than
twelve (12) months.  The Scheduled Commencement Date (as set forth in the Basic
Lease Information Sheet as Item 9) represents merely the parties' estimate of
                           ------
the Term Commencement Date and is the date before which Tenant is not obligated
to accept possession of the Premises. If the Premises are Substantially Complete
prior to the Scheduled Commencement Date, Tenant shall have the option to take
occupancy of the Premises and the Term Commencement Date shall be the date
Tenant commences business therein.  Landlord shall provide Tenant as much notice
as circumstances reasonably allow of the date when Landlord expects to achieve
Substantial Completion, based upon the progress of the work.  The covenants and
conditions of this Lease shall be effective as of the mutual execution of this
Lease notwithstanding the Term Commencement Date set forth herein.

     5.   Extension Term. The first sentence of Section 2.1(b) is amended to
                                                -------------
read as follows:

     Provided that (a) no Event of Default has occurred and not been cured prior
     to such time, and (b) Tenant is not in default of this Lease at the time of
     exercise or at any time thereafter prior to the scheduled Expiration Date,
     Tenant shall have two (2) consecutive options to extend the Term of this
     Lease with respect to any one or more of the Buildings (the

                                       2
<PAGE>

     "Extension Options") for the number of years and/or months set forth as the
     "Extension Terms" in the Basic Lease Information Sheet as Item 10,
                                                               -------
     commencing on the day after the expiration of the Initial Term or the first
     Extension Term for such Building, as applicable, and continuing through the
     Expiration Date, subject to all of the terms and conditions of this Lease,
     except that (i) Base Rent shall be adjusted as provided in Section 2.6(b),
                                                                -------------
     (ii) Landlord shall have no obligation to alter the Premises for the
     Extension Terms, and (iii) Tenant shall not have any additional rights to
     extend the Term, except to the extent an Extension Option remains to be
     exercised hereunder. Tenant shall provide Landlord with irrevocable written
     notice of Tenant's intent to exercise each Extension Option no later than
     fifteen (15) months prior to the expiration of the Initial Term or the
     first Extension Term for such Building, as applicable.

     6.   Signage. The following provisions shall fully replace and supercede
Section 5.6(b) of the Lease:
-------------

     (b)  Limited Right to Exterior Signage. So long as Tenant is leasing and
     occupying (which shall include for purposes hereof space initially
     subleased prior to Tenant's occupancy) a minimum of three (3) full floors
     in the South Building and Tenant is not in default under this Lease, Tenant
     shall have the exclusive right, at Tenant's sole cost and expense, to
     install and maintain a sign identifying Onyx Software Corporation (a
     "Tenant Sign") on the upper portion of the South Building in a location
     selected by Landlord and approved by the City of Bellevue. The Tenant Sign
     shall be the highest exterior sign permitted on the South Building that is
     visible from Interstate 405. In addition, Tenant shall have the exclusive
     right without charge to install one additional sign per Building (each of
     which shall be referred to herein as a "Lower Tenant Sign") (i) on the
     exterior of the East Building below the third floor windows facing NE 12th
     Street, and (ii) on the exterior of the South Building below the third
     floor windows facing 112th Avenue NE. The design and method of installation
     of all signs hereunder shall be subject to Landlord's reasonable approval
     and all City of Bellevue and other applicable governmental requirements.
     The exclusive right provided in the preceding sentences shall not apply
     with respect to typical retail signage for retail tenants of the Project.
     Tenant must submit detailed plans for all signs hereunder to Landlord for
     review and approval before Tenant installs the signs on the exterior of
     either Building. Tenant shall remove the Tenant Sign and Lower Tenant Signs
     and shall restore each Building to its condition prior to installation of
     the signage, at Tenant's sole cost and expense, (A) at the end of the Lease
     Term, or (B) if Tenant no longer leases and occupies at least one (1) full
     floor in such Building, or (C) upon request by Landlord if an Event of
     Default is outstanding under this Lease. The right to install and maintain
     the signs hereunder is personal to Onyx Software Corporation and shall not
     be assignable to any other party without the Landlord's prior written
     consent which may be given or withheld in Landlord's sole discretion. Any
     change in the Tenant Signs or the Lower Tenant Signs requested by Tenant
     shall be subject to Landlord's prior written approval, which shall not be
     unreasonably withheld (unless in Landlord's opinion such change may
     adversely affect the exterior appearance of the Project); provided,
     however, that with respect to any requested change in the Tenant Signs or
     the Lower Tenant Signs to reflect the name of a Permitted Transferee or a
     new name for Onyx Software Corporation, Landlord shall not unreasonably
     withhold its approval unless, in Landlord's judgment, the proposed new name
     will: (1) have an adverse effect on the value of the Project (including any
     adverse effect, in Landlord's judgment, on its ability to lease space in
     the Project) or its

                                       3
<PAGE>

     reputation; (2) be offensive; or (3) violate the provisions of any other
     tenant lease in the Project.

     7.   Entry for Repairs, Inspection, Posting Notices, etc. The second
sentence of Section 6.10 is amended to read as follows:
            ------------

     Unless Tenant is in default, Landlord shall only show the Premises to
     prospective tenants during the last twelve (12) months of the Initial Term
     with respect to each Building, if Tenant has not exercised an Extension
     Option, or during the last twelve (12) months of either Extension Term with
     respect to each Building.

     8.   Surrender. The first two sentences of Section 6.13 are amended to read
                                                ------------
as follows:

     On or before the ninetieth (90th) day preceding the Expiration Date for
     each Building, Tenant shall notify Landlord in writing of the precise date
     upon which Tenant plans to surrender the Premises to Landlord.  On
     expiration of the Term for any Building, Tenant shall quit and surrender
     that portion of the Premises located in such Building to Landlord, broom
     clean, in good order, condition and repair as required by this Lease, with
     all of Tenant's movable equipment, furniture, trade fixtures and other
     personal property removed therefrom (ordinary wear and tear and damage to
     an extent consistent with the Premises remaining in good condition and
     casualty damage which is not required to be restored by Tenant pursuant to
     Section 12 excepted).
     ----------

     9.   Assignment or Sublease; Landlord's Options. The first sentence of
Section 8.2 is amended to read as follows:

conditions of the Lease, the terms, conditions and provisions of this Second
Amendment shall prevail.

     16.  No Further Amendment.  Except as expressly modified by this Second
Amendment, all terms, covenants and provisions of the Lease shall remain
unmodified and in full force and effect and are hereby expressly ratified and
confirmed.

     17.  Entire Agreement. This Second Amendment reflects the entire agreement
of the parties with respect to amending the terms of the Lease and this Second
Amendment supersedes any and all correspondence and oral agreements between the
parties hereto regarding the amendment of the Lease which are prior in time to
this Second Amendment. With respect to the subject matter hereof, neither party
will be bound by any understanding, agreement, promise, representation or
stipulation, express or implied, not specified herein.

     18.  Counterparts.  This Second Amendment may be executed in counterparts,
each of which will be deemed to be an original, but all of which together will
constitute one and the same document.

Landlord shall each indemnify, defend and hold the other party harmless from and
against any and all liabilities for commissions or other compensation or charges
claimed by any other broker or agent based on dealings with the indemnifying
party with respect to this Lease.

     IN WITNESS WHEREOF, the parties hereto have executed this Second Amendment
in triplicate originals as of the day and year first above written.

"Agent") for itself and the Lenders (as defined in the Loan and Security
Agreement), on the one hand, and ONYX SOFTWARE CORPORATION ("Grantor"), on the
other hand.

                                   RECITALS
                                   --------

     A.        Agent and Lenders have agreed to make certain advances of money
and to extend certain financial accommodation to Grantor (the "Loans") in the
amounts and manner set forth in that certain Loan and Security Agreement by and
between Agent, Lenders, and Grantor dated as of even date herewith (as the same
may be amended, modified or supplemented from time to time, the "Loan
Agreement"; capitalized terms used herein are used as defined in the Loan
Agreement). Agent and Lenders are willing to make the Loans to Grantor, but only
upon the condition, among others, that Grantor shall grant to Agent for the
ratable benefit of Lenders, a security interest in certain Copyrights,
Trademarks, Patents, and Mask Works to secure the obligations of Grantor under
the Loan Agreement.

     B.        Pursuant to the terms of the Loan Agreement, Grantor has granted
to Agent for the ratable benefit of Lenders, a security interest in all of
Grantor's right, title and interest, whether presently existing or hereafter
acquired, in, to and under all of the Collateral.

     NOW, THEREFORE, for good and valuable consideration, receipt of which is
hereby acknowledged, and intending to be legally bound, as collateral security
for the prompt and complete payment when due of its obligations under the Loan
Agreement, Grantor hereby represents, warrants, covenants and agrees as follows:

                                   AGREEMENT
                                   ---------
     To secure its obligations under the Loan Agreement, Grantor grants and
pledges to Agent for the ratable benefit of Silicon Valley Bank and Comerica
Bank-California (collectively, "Lenders"), a security interest in all of
Grantor's right, title and interest in, to and under its Intellectual Property
Collateral (including without limitation those Copyrights, Patents, Trademarks
and Mask Works listed on Schedules A, B, C, and D hereto), and including without
limitation all proceeds thereof (such as, by way of example but not by way of
limitation, license royalties and proceeds of infringement suits), the right to
sue for past, present and future infringements, all rights corresponding thereto
throughout the world and all re-issues, divisions continuations, renewals,
extensions and continuations-in-part thereof.

     This security interest is granted in conjunction with the security interest
granted to Agent for the ratable benefit of Lenders, under the Loan Agreement.
The rights and remedies of Agent and Lenders with respect to the security
interest granted hereby are in addition to those set forth in the Loan Agreement
and the other Loan Documents, and those which are now or hereafter available to
Agent and Lenders as a matter of law or equity. Each right, power and remedy of
Agent and Lenders provided for herein or in the Loan Agreement or any of the
Loan Documents, or now or hereafter existing at law or in equity shall be
cumulative and concurrent and shall be in addition to
<PAGE>

every right, power or remedy provided for herein and the exercise by Agent and
Lenders of any one or more of the rights, powers or remedies provided for in
this Intellectual Property Security Agreement, the Loan Agreement or any of the
other Loan Documents, or now or hereafter existing at law or in equity, shall
not preclude the simultaneous or later exercise by any person, including Agent
and Lenders, of any or all other rights, powers or remedies.

     IN WITNESS WHEREOF, the parties have cause this Intellectual Property
Security Agreement to be duly executed by its officers thereunto duly authorized
as of the first date written above.
