by and between BENGREEN, L.L.C., an Oregon limited liability company, with its
address at 1022 SW Salmon Street, Suite 450, Portland, Oregon 97205

2200 Mission College Blvd., Santa Clara, CA 95052 ("Tenant").

1.  PREMISES AND TERM

         a. Premises. In consideration of the covenants and agreements herein
contained, Landlord does hereby lease, let and demise unto Tenant and Tenant
leases from Landlord, the space depicted on Exhibit "A" attached hereto (the
"Premises"), which contains 39,355 square feet, and which is located in Building
C, (the "Building"), all of which is in the Ronler Corporate Center (the "Park")
in Hillsboro, Oregon, which is legally described in Exhibit "B," attached
hereto. Tenant's Premises represent approximately twenty-five (25) percent of
the total existing square footage of 157,388 square feet within the Park. This
percentage shall be adjusted from time to time if more square footage is
constructed at the Park, and the percentage shall be computed by dividing the
square footage of the Premises by the total rentable square footage contained in
the Park, as determined by Landlord at its cost, using NAIOP standards. The
resulting percentage shall, upon written notice to Tenant, be used as Tenant's
proportionate share in determining Tenant's share of taxes, insurance,
assessments and operating expenses of the Park. Landlord reserves the right from
time to time to add to the real property which comprises the Park to include one
or more adjacent parcels. In the event that the inclusion of such additional
real property results in an increase of the total square footage of the Park,
Tenant's percentage shall be adjusted accordingly. Tenant shall have the right
to use, in common with others, the common areas of the Park.

         b. Possession. Landlord has completed the Landlord's Improvements, as
shown on Exhibit "C." Landlord shall deliver, and Tenant shall accept, the
Premises, upon the date that both Tenant and Landlord have executed this Lease
and Tenant has paid the first month of Base Monthly Rent. Landlord warrants that
as of the date of delivery of possession, the Premises will have been
constructed in accordance with all applicable recorded covenants, conditions and
restrictions and all applicable zoning, municipal, county, state and federal
laws, codes, ordinances and regulations (including ADA), governing and
regulating the development of the Park, construction of the Building and
construction of other improvements to the Park.

         c. Term. Landlord leases the Premises to Tenant for a term of eighty
four (84) months, commencing on March 1, 2001, ( the "Commencement Date"), and
continuing through the end of the eighty-fourth full calendar month after the
Commencement Date, February 29, 2008 ("Lease Term"). Notwithstanding the
foregoing, provided that Tenant is not then in default of this Lease, Tenant may
terminate this Lease as of February 28, 2006, by giving Landlord written notice
on or before September 1, 2005 that Tenant will terminate the Lease, and paying
Landlord the sum of One Hundred One Thousand Seven Hundred Twenty-Nine Dollars
and Twenty Cents ($101,729.20), which sum shall be paid to Landlord at the same
time that Tenant gives Landlord written notice of the exercise of its right to
terminate the Lease. In the event that Tenant fails to give Landlord timely
notice and make the payment on or before September 1, 2005, Tenant's right to
terminate the Lease shall lapse and be of no further effect. Notwithstanding the
foregoing, in consideration of the additional Base Monthly Rent to be paid, in
the event that Tenant exercises its right hereunder to the assign the Lease to
Convera, as allowed by Section 12 below, then the Lease Term shall terminate at
the end of the sixtieth full calendar month after the Commencement Date,
February 28,2006. Both Intel Corporation and Convera shall have the right to
exercise the Option to Renew as set out in the Addendum at the end of their
respective Lease Terms; provided however, if at the end of Convera's shortened
Lease Term, Convera does not elect to exercise the Option to Renew; and provided
the Lease is not then in default, Landlord will allow Convera to assign the
Lease back to Intel Corporation for the remainder of what would have been Intel
Corporation's original Lease Term. The Base Monthly Rent for the remainder of
the Lease Term will then revert back to the lesser dollar value per square foot
and shall be $44,081.30 per month, commencing March 1, 2007 and shall increase,
as set out in the Basic Lease Information in accordance with the established
rent for Intel Corporation. Intel Corporation and Convera must notify Landlord
on or before September 1, 2005, whether Convera will exercise the Option to
Renew, assign the Lease to Intel Corporation, or surrender the Premises in
accordance with the provisions of the Lease on February 28, 2006.

2.  BASE RENT AND SECURITY DEPOSIT

         a. Base Rent. Tenant agrees to pay to Landlord Base Rent for the
Premises, in advance, without demand, deduction, or set off, for the entire
Lease Term hereof, in monthly installments payable on the first day of each
calendar month, as set forth in the Basic Lease Information. First month's Base
Rent is due within five (5) days of receipt of a fully executed lease by Tenant.
In the event that Intel Corporation assigns this Lease to Convera, Base Monthly
Rent shall increase, as of the date of the assignment, to the amount of Base
Monthly Rent established for Convera for the year of the Lease Term in which the
Lease is assigned, as shown on the schedule of rent for Convera in the Basic
Lease Information.

         b. Security Deposit. In the event that the Lease is assigned to
Convera, the following provisions shall apply: Tenant agrees to deposit with
Landlord a security deposit in the amount specified in the Basic Lease
Information as security for the performance of Tenant's covenants and
obligations under this Lease, it being expressly understood and agreed that such
deposit is not an advance rental deposit, not the last month's rent, nor a
measure of Landlord's damage in the event of Tenant's default. If Tenant shall
at any time fail to make any payment or fail to keep or perform any term,
covenant, or condition on Tenant's part to be made or performed or kept under
this Lease, Landlord may, but shall not be obligated to, and without waiving or
releasing Tenant from any obligation under this Lease, apply the whole or any
part of the Security Deposit (a) to the extent of any sum due to Landlord; or
(b) to make any required payment on Tenant's behalf; or (c) to compensate
Landlord for any loss, damage, attorneys' fees, or expense sustained by Landlord
due to Tenant's default. In such event, Tenant shall, within five (5) days of
written demand by Landlord, remit to Landlord sufficient funds to restore the
Security Deposit to its original sum. Tenant's failure to do so shall be a
material breach of this Lease. Landlord shall not be required to keep the
Security Deposit separate from its general funds, and Tenant shall not be
entitled to interest on such deposit. Should Tenant comply with all of the
terms, covenants, and conditions of this Lease, and at the end of the Lease Term
leave the Premises in the condition required by this Lease, then the Security
Deposit, less any sums owing to Landlord, shall be returned to Tenant (or, at
Landlord's option to the last assignee of Tenant's interests hereunder) within
30 days after the termination of this Lease and vacancy of the Premises by
Tenant.

         c. Net Lease. This lease is intended to be a net lease, so that Tenant
shall pay all the costs associated with the Premises which are specifically set
out in this Lease, in addition to Base Rent. For purposes of the United States
Bankruptcy Code, all amounts payable by Tenant hereunder to Landlord or any
other party shall be rent.

3. USE. The Premises shall be used and occupied only for the uses set out in the
Basic Lease Information and for no other purpose without prior written approval
of Landlord, which approval shall not be unreasonably withheld, delayed or
conditioned. In connection with its use of the Premises and after commencement
of the Lease, Tenant shall, at Tenant's expense, comply with all applicable
laws, ordinances, and regulations of any public authority, including, but not
limited to, those requiring alterations of the Premises because of Tenant's
specific use; shall create no nuisance nor allow any objectionable liquid, odor,
or noise to be emitted from the Premises, shall store no gasoline or other

thereof. Landlord hereby confirms that Tenant's use as described in this Lease
conforms with all rules and regulations. Tenant shall not store, use or deposit,
or cause to be stored, used or deposited, on the Premises or anywhere in the
Building, any environmentally hazardous or potentially environmental hazardous

overload the floors or electrical circuits of the Premises or the Building.
Landlord shall have the right to approve, such approval not to be unreasonably

materials to be used or stored in the Building or on the Premises.

 4. SIGNS. Tenant may erect a sign on the exterior of the Building stating its
name, business, and product after first securing Landlord's written approval,
not to be unreasonably withheld, delayed or conditioned, of the size, color,
design, wording, and location, and all necessary governmental approvals.
Landlord shall have no obligation to approve any sign which differs in style,
size, color, design, or location from Landlord's standards or plans for the
Park's exterior signage (Exhibit E). All signs installed by Tenant shall be
removed upon termination of this Lease, with the sign location restored to its
former state. Tenant shall be responsible, at Tenant's sole cost and expense, to

Tenant shall also repair any damage to any area of the Premises or the Building
caused by Tenant's installation of Tenant's Improvements and shall be
responsible for the maintenance, repair and replacement of any structural

Tenant to any change of color of the exterior of the Building. Subject to the
preceding sentence, Landlord shall review and approve in writing such drawings

submittal by Tenant. Failure of Landlord to either approve such plans and
drawings, or to provide Tenant with Landlord's objections thereto, within five
(5) days after written notice from Tenant that Tenant has not received any
response to its submittal, shall be deemed approval of the plans and drawings as
submitted. Notwithstanding the foregoing, Tenant may make non-structural
alterations or improvements (as long as such improvements do not effect the
exterior of Building) which do not require a building permit, and the total hard
costs of which are less than $50,000.00 per occurrence. Prior to commencing any
construction, Tenant shall obtain a valid building permit issued by the
appropriate governmental agency. Upon termination of this Lease, any such

Landlord unless the terms of the Lease provide otherwise; or unless Landlord
requests that certain of the structural additions, or alterations or
improvements installed by Tenant be removed; provided however, that Tenant shall
not be required to remove any dropped ceilings, carpeting, ductwork, electrical
wiring and plumbing, HVAC systems, restrooms or interior floor-to-ceiling walls.
In such case, Tenant shall, at Tenant's sole cost and expense, promptly remove
the specified structural additions, alterations, or improvements and repair and

Landlord notice of its installation of such items within sixty (60) days of the
installation thereof, and Exhibit I shall then be amended to include such
additional items added to the Premises by Tenant, and Tenant and Landlord shall
initial any such changes to Exhibit I. Landlord shall not unreasonably withhold
consent to any additions to Exhibit I. During construction of any improvements
by Tenant, Tenant shall provide all security for its materials, offices, staging

of the Lease by Landlord and Tenant, and shall include a provision that the
coverage will not be canceled or materially altered without thirty (30) days'
advance written notice to Landlord. Landlord and Landlord's lender(s) shall be
named as additional insureds on such policies. The commercial general liability
policy shall insure on an occurrence and not a claims-made basis. The policies
shall be written with insurers qualified to do business in the state of Oregon,
carrying a financial rating by A.M. Best Reports of A or better. The limits of
the coverage under such policy shall not be deemed to limit the liability of
Tenant under this Lease. All polices of insurance carried by Tenant shall be
primary and non-contributing with any insurance of Landlord (any policy issued
to Landlord providing duplicate or similar coverage shall be deemed in excess of
Tenant's policies). Landlord reserves the right to change Tenant's insurance
requirements hereunder, from time to time, if reasonably necessary, to reflect
changes which may occur in the insurance industry in how policies and
endorsements are written.

     c. Tenant's Liability. Tenant hereby agrees that Landlord shall not be
liable for injury to Tenant's business or any loss of income therefrom or for
damage to the goods, wares, merchandise, equipment and vehicles or other
property of Tenant, Tenant's employees, invitees, customers, or any person in or
about the Premises unless caused by the negligence of Landlord, its employees,
agents or contractors; nor, unless caused by it or its contractors, employees or
agents negligence, shall Landlord be liable for injury to the person of Tenant,
Tenant's employees, agents or contractors and invitees, whether such damage or
injury is caused by or results from fire, steam, electricity, gas, water or
rain, or from defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures, or from any other cause; and whether the said
damage or injury results from conditions arising upon the Premises or upon other
portion of the Building or the Park, or from other sources or places, and
regardless of whether the cause of such damage or injury or the means of
repairing the same is inaccessible to Landlord or Tenant. Landlord shall not be
liable for any damages arising from any act or neglect of any other tenant, if
any, of the Park.

     d. Indemnity. Unless due to the negligence of Landlord, its employees,
agents or contractors, Tenant shall indemnify, defend and hold Landlord, its
principals, agents, successors and assigns harmless for, from and against any
and all claims, losses or damages arising from Tenant's use of the Premises, and
the related parking areas and common areas, or from the conduct of Tenant's
business or from any activity, work or things which may be permitted or suffered
by Tenant in or about the Premises and the Park, and shall further indemnify,
defend and hold Landlord harmless for, from and against any and all claims
arising from any material breach or material default in the performance of any
obligation on Tenant's part to be performed under the provisions of this Lease
or arising from any act, omission or negligence of Tenant or any of its agents,
contractors, employees, or invitees and from any and all reasonable costs,
attorneys' fees, expenses and liabilities incurred in the defense of any such
claim or action or proceeding brought thereon, including any appeal therefrom.
Tenant hereby assumes all risk or damage to property or injury to persons in or
about the Premises, and Tenant hereby waives all claims in respect thereof
against Landlord, except where said damage or injury arises out of the
negligence of Landlord, its agents or contractors. The foregoing indemnity shall
survive the expiration or earlier termination of this Lease, up to the extent of
the applicable statute of limitation.

     Landlord shall indemnify, defend and hold Tenant, its principals, agents,
successors and assigns harmless for, from and against any and all claims, losses
or damages arising from Landlord's negligence, and shall defend and hold Tenant
harmless for, from and against any and all claims arising from any material
breach or material default in the performance of any obligation on Landlord's
part to be performed under the provisions of this Lease or arising from any act,
omission or negligence of Landlord or any of its agents, contractors, or
employees and from any and all reasonable costs, attorneys' fees, expenses and
liabilities incurred in the defense of any such claim or action or proceeding
brought thereon, including any appeal therefrom. The foregoing indemnity shall
survive the expiration or earlier termination of this Lease, up to the extent of
any applicable statute of limitations.

     e. HVAC And Other  Systems.  Tenant shall  repair, replace and maintain the
HVAC and all other  systems  serving the Premises, at its own cost and expense.

     f. Personal Property Taxes: Tenant shall pay all personal property taxes
assessed against; (i) the Tenant Improvements installed by Tenant and (ii)
Tenant's trade fixtures and personal property, whether said taxes are assessed
separately and billed to Tenant directly, or are billed to Landlord as part of
Landlord's taxes for the Park.

10. CASUALTY DAMAGE

       a. Casualty Damage. If fire or other casualty cause damage to the
Premises in an amount exceeding thirty percent (30%) of the full
construction-replacement cost of the Premises, Landlord may elect to terminate
this Lease as of the date of the damage by notice in writing to Tenant. In the
event that the damage to the Premises is less than thirty percent of the full
construction-replacement cost of the Premises, or if more than thirty percent,
but Landlord elects not to terminate the Lease, Landlord shall promptly repair
the damage and restore the Landlord's Improvements to their former condition as
soon as practicable. Tenant's Improvements , trade fixtures, personal property
and any alterations to the Premises made by Tenant shall be replaced by Tenant
at Tenant's expense. In the event of such casualty, Tenant shall not be entitled
to any abatement of rent; instead, Tenant shall look to Tenant's Business
Interruption Insurance. Tenant shall not be entitled to any compensation or
damages from Landlord for loss of the use of the whole or part of the Premises
or the Park, or any inconvenience or annoyance occasioned by such damage or
reconstruction. Notwithstanding the foregoing, within fifteen (15) business days
of fire or casualty, Landlord shall provide to Tenant in writing a reasonable
estimate of the time required to repair the damage and restore the Landlord's
Improvements to their former condition. If such estimate exceeds one hundred
fifty (150) days, Tenant may terminate this lease by written notice to Landlord
to be given within fifteen business (15) days of receipt of Landlord's estimate,
after which Tenant's right to terminate shall lapse. The termination shall be
effective as of the date that Landlord receives the notice.

       b. Insurance. Landlord shall be responsible for insuring the Building at
full replacement cost with a standard inflation guard endorsement and at its
election with all perils, earthquake and such other endorsements and coverages
as are customary and reasonable, and Tenant shall be responsible for insuring
its systems, its construction, all Tenant Improvements installed by Tenant and
its personal property and trade fixtures located on the Premises. If any
activity by Tenant on the Premises causes Landlord's fire insurance rate to
increase, Tenant shall pay the amount of such increase promptly following
written demand from Landlord. Landlord shall carry commercial liability
insurance, with limits of not less than One Million Dollars ($1,000,000) for
injury to one person in one occurrence, Two Million Dollars ($2,000,000) for
injuries to more than one person in one occurrence, and Five Hundred Thousand
Dollars ($500,000) for property damage.

       c. Subrogation. Neither party shall be liable to the other for any loss
or damage to the Premises or either party's personal property or to any person
caused by any of the risks covered by an all risks of direct physical loss or
damage insurance policy or commercial general liability policy and there shall
be no subrogated claim by one party's insurance carrier against the other party
arising out of any such loss.

11. CONDEMNATION. If a condemning authority takes the entire Premises, or a
portion thereof which is sufficient to render the remainder unsuitable for
Tenant's use in Tenant's reasonable discretion, then Tenant may elect to
terminate this Lease effective on the date that title passes to the condemning
authority. Otherwise, Landlord shall proceed as soon as practicable to restore
the remaining Premises to a condition comparable to that existing at the time of
the taking. Rent shall be abated during the period of restoration to the extent
the Premises are reasonably usable by Tenant, and rent shall be reduced for the
remainder of the term in an amount equal to the reduction in rental value of the
Premises caused by the taking. For purposes of this Section only, a voluntary
sale or conveyance under threat and in lieu of condemnation, shall be deemed a
taking by eminent domain. Any condemnation proceeds shall belong solely to the
Landlord, except that Tenant shall be entitled to any separate award for loss of
or damage to Tenant, including damage to Tenant's trade fixtures, removable
personal property and unamortized tenant improvements that have been paid for by
Tenant. For that purpose, the cost of such improvements shall be amortized over
the original term of this Lease excluding any options. Nothing herein shall be
deemed to preclude Tenant from seeking or obtaining, nor shall it give Landlord
an interest in, any award to Tenant for damage for cessation or interruption of
Tenant's business; provided however that no claim of Tenant shall be in
derogation of Landlord's award.

12. ASSIGNMENT AND SUBLETTING. Tenant shall not transfer, alienate, hypothecate
or assign (collectively "assign") or sublease its interest under this Lease
without first obtaining Landlord's consent in writing, which consent shall not
be unreasonably withheld, delayed or conditioned. No consent in one instance
shall prevent this provision from applying to each subsequent instance. This
provision shall apply to all transfers by operation of law including, but not
limited to, mergers and changes in control of Tenant. No assignment shall
relieve Tenant of its obligation to make payments or perform other obligations
required by this Lease. If Tenant assigns this Lease for an amount in excess of
the rent called for by this Lease, fifty percent (50%) of such excess, excluding
all reasonable expenses incurred by Tenant and approved by Landlord, shall be
paid to Landlord promptly as it is received by Tenant. Any assignment or sublet
in violation of this Section shall be null and void. Notwithstanding the
foregoing, Tenant may assign its interest in the Lease and the Premises, or
sublease all or a portion of the Premises, to any wholly-owned affiliate or
subsidiary of INTEL CORPORATION, or to CONVERA, without Landlord's consent;
provided that CONVERA or such other wholly-owned affiliate or subsidiary of
INTEL CORPORATION, as the case may be, executes an Assignment and Assumption
Agreement in the form attached hereto as Exhibit F, and that the Lease is not in
default as of the date of such assignment. In the event that Tenant elects to
assign the Lease to CONVERA, prior to such assignment, and as a condition
thereof, Tenant and CONVERA shall submit CONVERA's financial statement and
balance sheet to Landlord for approval, along with any other financial
information reasonably requested by Landlord. In the event of an assignment by
INTEL CORPORATION to CONVERA, as of the date of such assignment to CONVERA,
INTEL CORPORATION shall be relieved from any future obligation on the Lease,
unless and until CONVERA assigns the Lease back to INTEL CORPORATION, as allowed
by Section 1.c above; in which case INTEL CORPORATION shall assume and agree to
pay all of Tenant's obligations under the Lease, and as shall execute and
deliver to Landlord an Assignment and Assumption in the form of Exhibit F. In
the event of any other assignment or sublease by INTEL CORPORATION to any other
party other than CONVERA, INTEL CORPORATION shall not be relieved of liability
hereunder.

13. DEFAULT

       Any of the following shall constitute a default by Tenant under this
Lease:

       a. Tenant's failure to pay rent or any other charge under this Lease when
due; provided however that Landlord shall first notify Tenant in writing of such
failure and allow Tenant ten (10) business days after such notice to make
payment; but further provided that Landlord shall have no obligation to give
Tenant such notice and time to cure more than two (2) times in a twelve (12)
month period.

       b. Failure to comply with any other terms or condition of this Lease,
other than payment of rent or any other charge, within thirty (30) days
following written notice from Landlord specifying the noncompliance. If such
noncompliance cannot be cured within the thirty (30) day period, this provision
shall be satisfied if Tenant commences correction within such period and
thereafter proceeds in good faith and with reasonable diligence to effect
compliance as soon as possible.

        c. Insolvency of Tenant; an assignment by Tenant for the benefit of
creditors; the filing by Tenant of a voluntary petition in bankruptcy; an
adjudication that Tenant is bankrupt or the appointment of a receiver of the
properties of Tenant; the filing of any involuntary petition of bankruptcy and
failure of Tenant to secure a dismissal of the petition within 30 days after
filing; attachment of or the levying of execution on the leasehold interest and
failure of Tenant to secure discharge of the attachment or release of the levy
of execution within 10 days shall constitute a default. If Tenant consists of
two or more individuals or business entities, the events of default specified in
this Section shall apply to each individual unless, within 10 days after an
event of default occurs, the remaining individuals produce evidence satisfactory
to Landlord that they have unconditionally acquired the interest of the one
causing the default. If the Lease has been assigned, the events of default so
specified shall apply only with respect to the one then exercising the rights of
Tenant under the lease.

       d. Subject to written notice from Landlord, failure of Tenant, for seven
(7) consecutive days or more, to occupy the Premises for one or more of the
purposes permitted under this lease, but only in the event that Tenant is also
in monetary or other default under this Lease, unless such failure is excused
under other provisions of this lease.


14. REMEDIES ON DEFAULT.

       a. Termination. In the event of a default, as specified in Section 13
above, the Lease may be terminated at the option of Landlord by written notice
to Tenant. Whether or not the Lease is terminated by the election of Landlord or
otherwise, Landlord shall be entitled to recover reasonable damages from Tenant
for the default. If the Lease is terminated, Landlord may reenter, take
possession of the premises, and remove any persons or property by legal action
with the use of reasonable force and without liability for damages and without
having accepted a surrender.

       b. Reletting. Following reentry or abandonment, Landlord may relet the
Premises and in that connection may make any suitable alterations or refurbish
the Premises, or both, or change the character or use of the Premises, but
Landlord shall not be required to relet for any use or purpose other than that
specified in the Lease, or which Landlord may reasonably consider injurious to
the Premises, or to any tenant that Landlord may reasonably consider
objectionable. Landlord may relet all or part of the Premises, for a term longer
or shorter than the term of this Lease, upon any reasonable terms and
conditions, including the granting of some rent-free occupancy or other rent
concession.

       c. Damages. In the event of termination or retaking of possession
following default, Landlord shall be entitled to recover immediately, without
waiting until the due date of any future rent or until the date fixed for
expiration of the Lease Term, the following amounts as damages:

       i. The loss of rent and other charges payable by Tenant from the date of
  default until a new tenant is, or with the exercise of reasonable efforts
  could have been, secured and paying out;
       ii. The reasonable costs of reentry and reletting, including without
limitation the cost of any cleanup, refurbishing, removal of Tenant's property
and fixtures, or any other expense occasioned by Tenant's default, including but
not limited to, any remodeling or repair costs, recovery of free rent or any
other monetary concessions made to a replacement tenant, attorney fees, court
costs, broker commissions, and advertising costs; and
       iii. Any excess of the value of the rent and all of Tenant's other
obligations under this Lease over the reasonable expected rent and other charges
from the Premises for the period commencing on the earlier of the date of trial
or the date the Premises are relet (or with the exercise of reasonable efforts
could be relet), and continuing through the end of the Lease Term. The present
value of future amounts will be computed using a discount rate equal to the
prime loan rate of Landlord's bank in effect on the date of trial. For the
purposes of this subsection c, Landlord shall have met the standard of
"reasonable efforts to relet or secure a new tenant" if Landlord has listed the
Premises with a licensed real estate broker in the Hillsboro, Oregon area who
has made commercially reasonable efforts to find a new tenant for the Premises.

       d. Right to Sue More than Once.  Landlord may sue periodically to recover
damages during the period corresponding to the remainder of the Lease Term, and
no action for damages shall bar a later actionfor damages subsequently accruing.

       e. Landlord's Right to Cure Defaults. If Tenant fails to perform any
obligation under this Lease, or shall fail to commence to perform said
obligation within thirty (30) days after written notice to Tenant by Landlord,
then Landlord shall have the option to do so, except in the case of an
emergency, in which case Landlord may cure immediately, without notice to
Tenant. All of Landlord's expenditures to correct the default shall be
reimbursed by Tenant on demand with interest at the rate of twelve percent (12%)
per annum from the date of expenditure by Landlord, or the highest amount
allowed by law if less than 12%. Such action by Landlord shall not waive any
other remedies available to Landlord because of the default.

       f. Remedies Cumulative. The foregoing remedies shall be in addition to
and shall not exclude any other remedy available to Landlord under applicable
law. A receipt by Landlord of rent or other payment with knowledge of the breach
of any covenant hereof shall not be deemed a waiver of such breach.

15. SURRENDER ON TERMINATION; HOLDOVER. On expiration or early termination of
this Lease, Tenant shall deliver all keys to Landlord, have final utility
readings made on the date of move out, and surrender the Premises clean and free
of debris inside and out, with all mechanical, electrical, and plumbing systems
in good operating condition, reasonable wear and tear excepted, all signage
removed and defacement corrected and all repairs called for under this Lease
completed. Subject to the provisions of Section 5 hereof, the Premises shall be
delivered in the same condition as at the commencement of the Lease Term,
subject only to (1) depreciation and wear and tear from ordinary use; (2) damage
by fire, explosion or other casualty; (3) repairs and restoration for which
Tenant is not responsible hereunder; (4) Tenant's improvements, alterations and
renovations to the Premises, unless Landlord has required that any such
improvements, alterations or renovations be removed in accordance with the
provisions of this Lease; and (5) Tenant's removal of its trade fixtures and
affixed personal property as listed on Exhibit I, as amended from time to time.
Tenant shall remove all of its furnishings and trade fixtures that remain
Tenant's property and restore all damage resulting from such removal. Failure to
remove shall be an abandonment of the property, and Landlord may dispose of it
in any manner without liability. If Tenant remains in the Premises after the
Lease expiration date, such continuance in possession by Tenant shall be deemed
to be month-to-month tenancy at the sufferance of Landlord, terminable upon
thirty (30) days' notice at any time by either Tenant or Landlord. All
provisions of this Lease, except those pertaining to term and rent, will apply
to the month-to-month tenancy. Tenant will pay Base Rent in the amount equal to
125% of the Base Rent for the last full calendar month during the Lease Term.
Notwithstanding the foregoing, Tenant shall be allowed to holdover at the then
current Monthly Base Rent for up to four (4) months immediately following the
Lease Term as may be extended by providing Landlord with one hundred eighty
(180)days advance written notice. All obligations of Tenant and Landlord
hereunder not fully performed as of the termination of the Lease Term shall
survive such termination, including without limitation, indemnity obligations,
payment obligations with respect to operating expenses, taxes and insurance and
obligations concerning the repair and condition of the Premises.

16. LANDLORD'S REPAIRS. Within ten (10) business days after written notice from
Tenant, Landlord shall immediately proceed to repair structural as well as
non-structural problems occurring in the roof, exterior walls, building
structure and foundations, and subject to section 7 of this Lease, Landlord may
include the costs of certain repairs in the operating expenses of the Park which
are passed through to Tenant. Tenant shall repair and pay for any damage to such
items to be maintained by Landlord caused by any act, omission or negligence of
Tenant, or Tenant's employees, agents, licenses or invitees, or caused by
Tenant's default hereunder. The Term "walls" as used herein shall not include
windows, glass or plate glass, doors, special storefronts or office entries.
Tenant shall promptly give Landlord written notice of defect or need for
repairs, after which Landlord shall within thirty (30) days repair same or cure
such defect, or if repair or cure can not be accomplished within 30 days,
diligently commence such cure within said 30 day period. In no event will
Landlord be responsible for paying incidental or consequential damages resulting
from Landlord's failure to cure such defects. Notwithstanding the above, in the
event of an emergency to which Landlord has not immediately responded after
notice from Tenant, or where Landlord has not commenced a repair within thirty
(30) days notice from Tenant, Tenant may commence such repair without notice to
Landlord. In such case, all of Tenant's reasonable expenditures shall be
reimbursed by Landlord on demand with interest at the rate of twelve percent
(12%) per annum from the date of expenditure by Tenant, or the highest amount
allowed by law if less than 12%. Subject to Landlord's right to charge back
expenses to Tenant in accordance with Section 7 above, Landlord shall maintain
the common areas of the Park, including landscaping, snow removal, parking lot,
etc.

17. LATE CHARGES. Landlord may impose a late charge for rent or other charges
due from Tenant which are not paid when due as set out below; provided however,
that Landlord shall first notify Tenant in writing of Landlord's intention to
impose such late charge and allow Tenant ten (10) business days after such
notice to make payments; but further provided that Landlord shall have no
obligation to give Tenant such notice and time to cure more than two (2) times
in a twelve-month period, and such notice may be given in the same notice that
Landlord is required to give Tenant in accordance with Section 13 (a) above.
Except as set out in the foregoing sentence, a late charge shall accrue on the
sixth business day following the due date. The late charge shall be equal to One
Hundred Dollars ($100.00) per day until the amount due is paid in full. The
collection of a late charge from Tenant by Landlord shall not waive any other
remedies available to Landlord on account of Tenant's default. Tenant shall be
entitled to collect a late charge from Landlord in accordance with the terms of
this section in the event that Landlord fails to timely pay any amount due to
Tenant in accordance with section 7 (d), above, Reconciliations or fails to
reimburse Tenant in accordance with Section 16 .

18. SUBORDINATION. This Lease may, at Landlord's option, be made subordinate to
any ground lease, mortgage, or deed of trust which may hereafter affect the
Premises or the Park; provided however, that in the event of a termination of
any such ground lease or upon the foreclosure of any such mortgage or deed of
trust, so long as Tenant is not in default or is diligently proceeding to cure
default, Tenant's rights under this Lease shall continue and Tenant's quiet
enjoyment of the Premises shall not be disturbed. Tenant or Tenant's successors
in interest will execute and deliver any reasonable and customary documents
required to effectuate such subordination to any ground lease, mortgage, or deed
of trust in the form reasonably required by Landlord or its lender or in the
forms attached hereto as Exhibit J, within fifteen (15) business days of receipt
of such documents from Landlord.

19. ESTOPPEL CERTIFICATE

       a. Tenant shall, at any time upon not less than fifteen (15) business
days' prior written notice from Landlord, execute, acknowledge and deliver to
Landlord a statement in writing certifying that the Lease is in full force and
effect (or, certifying that this Lease, as so modified, is in full force and
effect), the amount of rent and other charges due, and the date to which the
rent and other charges are paid in advance, if any, and acknowledging that there
are not, to Tenant's knowledge, any uncured defaults on the part of the Landlord
hereunder, or specifying such defaults, if any are claimed. Any such statement
may be conclusively relied upon by any prospective purchaser or party making a
loan to Landlord.

       b. Tenant's failure to deliver such statement within such time shall be
conclusive upon Tenant that this Lease is in full force and effect, without
modification except as may be represented by Landlord, that there are no uncured
defaults in Landlord's performance, and that not more than one month's Base Rent
has been paid in advance.

20. MODIFICATIONS TO PREMISES. If Tenant wants to make any modifications to the
Premises, Tenant shall, at Tenant's sole cost and expense, construct the
improvements on the Premises, all of which are subject to Section 5 above and
the tenant improvement allowance in the Addendum.

21. HAZARDOUS SUBSTANCES. Tenant shall not, and shall not cause any party under
Tenant's control or invited on the Premises or the Park by Tenant, to construct,
use, deposit, store, dispose, place or locate on or about the Premises any
hazardous substances (as later defined) without the prior written consent of
Landlord, which shall not be unreasonably withheld as long as Tenant
demonstrates to Landlord's reasonable satisfaction that (a) the nature and
quality of any hazardous substances are necessary, useful, and appropriate to
Tenant's business conducted at the Premises: (b) the hazardous substances will
be used, kept and stored with the highest degree of care and in a manner that
complies with all governmental laws, ordinances, regulations, orders and
policies regulating any such hazardous material so brought upon or used or kept
in or about the Premises, (c) such hazardous substances are disposed of off the
Premises and the Park, in a disposal site licensed or designated for such
hazardous substances, with the utmost care and caution and in a manner
consistent with applicable governmental laws, ordinances, regulations, orders
and policies; (d) Tenant pays, as additional rent, any increase in the premiums
charged Landlord for insurance coverage by reason of Tenant's' storage,
placement, location, or use of hazardous substances or any premiums for
additional insurance coverages deemed appropriate by Landlord because of the
presence of such hazardous substances; and (e) Tenant procures any insurance
coverages reasonably demanded by Landlord. Tenant shall indemnify, defend, and
hold Landlord, its principals, agents, successors and assigns, harmless for,
from and against, any and all claims, judgments, damages, penalties, fines,
costs, liabilities, or losses (including, without limitation, diminution in
value of the Premises, damages for the loss or restrictions on use of rentable
or usable space or of any amenity of the Premises, damages arising from any
adverse impact on marketing of space, and sums paid in settlement of claims,
attorneys' fees, consultant fees, and expert fees) which arise during or after
the Lease Term as a result of contamination by hazardous substances as a result
of Tenant's use or activities, or of Tenant's agents or contractors. This
indemnification of Landlord by Tenant includes, without limitation, reasonable
costs incurred in connection with any investigation of the site conditions or
any cleanup, remediation, removal, or restoration work required by any federal,
state, or local governmental agency or political subdivision because of
hazardous substances present in the soil or ground water on or under the
Premises as a result of the actions of Tenant or any other party under its
control or invited on the Premises or the Park by Tenant . Without limiting the
foregoing, if the presence of any hazardous substances on the Premises caused or
permitted by Tenant or its agents or contractors results in any contamination of
the Premises, Tenant shall promptly take all actions, at its sole expense, as
are necessary to return the Premises to the condition existing prior to the
release of any such hazardous substance to the Premises, provided that
Landlord's approval of such actions shall first be obtained, which approval
shall not be unreasonably withheld so long as such action would not potentially
have any material adverse long-term or short-term effect on the Premises. The
term "hazardous substances" shall include (a) any chemical, material, element,
compound, solution, mixture, substance, or other matter of any kind whatsoever
which is a "hazardous substance", "hazardous material", "toxic substance" or
"solid waste" as defined in CERCLA, as amended by the Superfund Amendments and
Reauthorization Act of 1986 ("SARA"), the Resource Conservation and Recovery Act
("RCRA") and the Hazardous Materials Transportation Table (49 CFR 172.101 and
amendments thereto) or by the Environmental Protection Agency (or any successor
agency) as hazardous substances (40 CFR Part 302 and amendments thereto); and
such other substances which are or become regulated or classified as hazardous
or toxic under applicable local, state or federal laws or regulations, and (b)
asbestos or materials containing asbestos, petroleum products, or such other
substances, materials, and wastes that are or become regulated under the
applicable local, state, or federal laws or regulations from time to time.
Landlord shall indemnify and hold harmless Tenant, its principals, agents,
successors and assigns, harmless for, from and against, any and all claims,
judgments, damages, penalties, fines, costs, liabilities, or losses (including,
without limitation, attorneys' fees, consultant fees, and expert fees) which
arise during or after the Lease Term as a result of contamination of the
Premises or Park by hazardous substances which existed at or under the Park
prior to the effective date of the Lease and from the activities of Landlord or
its employees or agents at the Park. The foregoing indemnities shall survive the
expiration or earlier termination of this lease, up to the extent of the
applicable statute of limitation.

22.  RELOCATION.  INTENTIONALLY DELETED

23. BROKERAGE FEES. Landlord agrees to pay a real estate fee to Melvin Mark
Brokerage Company, which fee shall be shared with Grubb and Ellis. Landlord
agrees to indemnify and hold Tenant free and harmless from and against all
claims for brokerage commissions or fees and/or finder's fees by any person or
entity claiming to have been retained by Landlord in connection with this
transaction. Tenant agrees to indemnify and hold Landlord free and harmless from
and against all claims for brokerage commissions or fees and/or finder's fees
from any person or entity claiming to have been retained by Tenant in connection
with this transaction, or to be the procuring cause of this transaction, other
than the real estate fee which Landlord has agreed to pay hereunder to the
parties named in this section.

24. GENERAL PROVISIONS

       a. Waiver by either party of strict performance of any provision or this
Lease shall not be a waiver nor prejudice the party's right otherwise to require
performance of the same provision or any other provisions.

       b. Landlord shall have the right to enter upon the Premises, upon
reasonable notice, during normal business hours, except in the case of an
emergency when no notice shall be required, to determine Tenant's compliance
with this Lease, to make necessary repairs to the Building or the Premises, or
during the last six (6) months of the Lease Term if Tenant has not extended the
term, to show the Premises to any prospective tenant or purchasers. Landlord may
place and maintain upon the Premises notices for leasing or sale of the
Premises.

       c. If this Lease commences or terminates at a time other than the
beginning or end of one of the specified rental periods, then the rent and other
charges to be paid by Tenant as required by this Lease shall be prorated as of
such date.

       d. Landlord warrants that, so long as Tenant complies with all terms of
this Lease, it shall be entitled to peaceable and undisturbed possession of the
Premises, free from any eviction or disturbance by Landlord or persons claiming
through Landlord or its successors or assigns.

       e. The term "Landlord" as used herein shall mean only the owner of the
fee title to the Park. In the event of any transfer of such title or interest,
Landlord herein named (and in case of any subsequent transfers, the then
Landlord) shall be relieved from and after the date of such transfer of all
liability as respects Landlord's obligations thereafter to be performed;
provided that any funds in the hands of Landlord, or the then Landlord at the
time of such transfer, in which Tenant has an interest, shall be delivered to
the succeeding Landlord. Tenant shall attorn to any party who succeeds to
Landlord's interest and in return such successor shall not disturb Tenant's
possession of the Premises. If Landlord neglects or fails to perform its
obligations under this Lease within thirty (30) days after written notice of
default (or if more than thirty (30) days shall be required because of the
nature of the default, if Landlord fails to proceed diligently to cure such
default after written notice thereof), then Landlord shall be liable to Tenant
for damages sustained by Tenant as a result of Landlord's breach and Tenant may
cure such default by Landlord on behalf of, and at the sole expense of,
Landlord, and Landlord shall reimburse Tenant for its costs and expenses in
connection therewith including interest at the rate of twelve percent (12%) per
annum from the date of expenditure by Tenant, or the highest amount allowed by
law if less than 12%, within thirty (30) days after Tenant's delivery to
Landlord of an invoice therefor; provided, however, that any money judgment
resulting from any such default or other claim arising under this Lease shall be
satisfied only out of the assets of the Park or the rents, issues, profits and
other income received from the operation of the Park, and no other real,
personal or mixed property of Landlord, (the term "Landlord" for purposes of
this paragraph only shall mean any and all members, if any, which comprise
Landlord). Tenant will not institute any further action, suit, claim or demand,
in law or in equity, against Landlord for or on the account of such deficiency.
Tenant hereby waives, to the extent waivable under law, any right to satisfy
said money judgment against Landlord except from the aforementioned assets.

       f. If the Premises or any part thereof are at any time subject to a first
mortgage or a first deed of trust and this Lease or the rentals due from Tenant
hereunder are assigned to such mortgagee, trustee or beneficiary (called
"Assignee" for purposes of this Section only) and Tenant is given written notice
thereof, including the post office address of such Assignee, then Tenant shall
give written notice of any default by Landlord to such Assignee by Certified or
Registered mail, with a copy to Landlord, specifying the default in reasonable
detail, and affording such Assignee an additional thirty (30) days following
Assignee's receipt of such notice of default to make performance for and on
behalf of Landlord; provided that if such default cannot reasonably be cured
within such additional 30-day period, then such mortgagee or beneficiary shall
have such additional time to cure the default as is reasonably necessary under
the circumstances; but further provided that Tenant shall not be required to
allow said additional time to cure in the case of an emergency. If and when the
said Assignee has made performance on behalf of Landlord, such default shall be
deemed cured.

       g. Notices between the parties relating to this Lease shall be in
writing, effective when delivered, or if mailed, effective on the third day
following mailing, postage prepaid, certified mail, return receipt requested, to
the address for the party stated in this Lease or to such other address as
either party may specify by notice to the other. Rent shall be payable to
Landlord at the same address.

Parking

Landlord shall maintain a parking ratio at the Park of four (4) parking spaces
per 1000 square feet of office space in Phase II of the Park, which consists of
Buildings C and D, during the entire Lease Term. The parking spaces shown on
Exhibit A shall be marked as "Visitor Spaces" for Tenant.

Tenant Improvements:

Tenant shall construct the tenant improvements which are listed on Exhibit "D"
and such other improvements agreed to by Landlord and Tenant in accordance with
Section 5(b) of the Lease ("Tenant's Improvements") Landlord shall provide
Tenant with a Tenant Improvement Allowance in the amount of $1,180,650.00, to be
applied towards HVAC, lighting, electrical systems, space plans, working
drawings, engineering costs, permit fees, utility hook-up fees and other related
tenant improvements. Landlord shall pay the entire Tenant Improvement Allowance
to Tenant upon the occurrence of the following: Tenant has received a final
certificate of occupancy for the Premises, has obtained final lien waivers from
all contractors providing work and/or materials to the Premises and provided
copies to Landlord, and has taken possession of the Premises and is paying rent.
As to all Tenant Improvements installed by Tenant which Landlord has a right to
require Tenant to remove in accordance with the provisions of Section 5 (b) and
Exhibit I, as amended from time to time, Landlord shall give Tenant notice, no
later than ninety (90) days prior to the termination or expiration date of this
Lease, of which of those Tenant Improvements listed on Exhibit I. Landlord will
require Tenant to remove or restore, in order to allow Tenant time prior to the
end of such term to remove the Tenant Improvements as required by Landlord.

Contractors:

All Tenant improvement work, as well as any subsequent major work in the
Premises shall be performed by Landlord's contractor or other contractor
selected by Tenant and acceptable to the Landlord, such consent shall not be
unreasonably withheld or delayed. In no event shall Tenant be obligated to use
Landlord's contractor if his costs are greater than the lowest bid received by
Tenant. Landlord approves Baugh Construction as contractor for the Tenant
Improvements.

Option to Renew:

Provided no default under any of the provisions or covenants of this Lease has
occurred and is continuing, Tenant shall be afforded the opportunity of
extending the term of this Lease for three (3) periods of three (3) additional
years each (an "Option Term") by giving written notice (the "Exercise Notice")
of its intent to extend the term of this Lease no less than one hundred eighty
(180) days prior to the expiration of the initial Lease Term, or the Option
Term, as the case may be. The exercise of the option in accordance with the
provisions of this Section shall be effective to make the Option Term binding
upon Landlord and Tenant, with the exception of the determination of the Monthly
Base Rent, which shall be made in accordance with this Section. If an option is
duly exercised, the term of this Lease shall be automatically extended upon all
of the same terms, conditions and covenants as are set forth in this Lease with
the exception of Monthly Base Rent for the Premises, which shall be, for each
Option Term, ninety-five percent (95%) of the Fair Market Rent for the Premises
at the time the option is exercised (as determined below) and there shall be no
further options to extend or renew this Lease, except as specifically provided
herein. Should Tenant fail to exercise any of its options as provided herein,
the entire option privilege shall be extinguished and the term of this Lease
shall end upon the expiration of the initial Lease Term, or the current Option
Term, as the case may be. If default has occurred under this Lease which has not
been cured on the date Tenant exercises an option, such exercise shall be null
and void and of no force and effect. If Tenant is in default of this Lease
beyond any applicable cure period and is not diligently proceeding to cure such
default on the date an Option Term commences, Landlord may, in its sole
discretion, terminate this Lease by delivery of a written termination notice to
Tenant.

"Fair Market Rent" for the Premises shall be determined as follows:

"Fair Market Rent" shall mean the minimum rent being charged for comparable
space in the Hillsboro, Oregon, area with similar amenities and fixtures taking
into account the size of the Premises and Tenant's financial strength but
excluding any specialized improvements, alterations and fixtures that are
related solely to Tenant's use and making an adjustment to reflect that no
tenant improvement allowances, broker's commissions, free rent or other
incentives will be paid to Tenant. Fair Market Rent as of the date of an Option
Term shall be determined by Landlord with written notice (the "Notice") given to
Tenant not later than thirty (30) days after receipt of the Exercise Notice,
subject to Tenant's right to arbitration as hereinafter provided. If Tenant
disputes the amount claimed by Landlord as Fair Market Rent, Tenant and Landlord
shall use their best efforts to come to agreement on the Fair Market Rent. If
Landlord and Tenant cannot agree on the Fair Market Rent, Tenant may require
that Landlord submit the dispute to arbitration. Failure on the part of Tenant
to demand arbitration within thirty (30) days after receipt of the Notice from
Landlord shall bind Tenant to the Fair Market Rent determined by Landlord. The
arbitration shall be conducted and determined in Portland, Oregon in accordance
with the then prevailing rules of the Arbitration Services of Portland or its
successor for arbitration of real estate valuation disputes, except that the
procedures mandated by such rules shall be modified as follows:

         (1) Tenant shall make demand for arbitration in writing within thirty
(30) days after receipt of the Notice, specifying the name and address of the
person to act as arbitrator on Tenant's behalf. The arbitrator shall be a real
estate broker with at least ten (10) years full-time experience who is familiar
with the Fair Market Rent of space similar to the Premises in the Hillsboro,
Oregon, metropolitan area. Within ten (10) business days after the service of
Tenant's demand for arbitration, Landlord shall give notice to Tenant specifying
the name and address of the person designated by Landlord to act as arbitrator
on Landlord's behalf, which person shall be similarly qualified. If Landlord
fails to notify Tenant of the appointment of Landlord's arbitrator within the
time specified, then the arbitrator appointed by Tenant shall be the arbitrator
to determine the Fair Market Rent for the Premises.

         (2) If two arbitrators are chosen, the arbitrators so chosen shall meet
within ten (10) days after the second arbitrator is appointed and shall appoint
a neutral arbitrator who shall be a competent and impartial person with
qualifications similar to those required of the first two arbitrators. If they
are unable to agree upon such appointment within five (5) days, the neutral
arbitrator shall be selected by the presiding judge of the Washington County
Circuit Court.

         (3) The Fair Market Rent shall be agreed by the three arbitrators. If
the arbitrators cannot come to agreement, then the three arbitrators shall
determine the Fair Market Rent in accordance with the following procedures: Each
party appointed arbitrator shall state, in writing, such arbitrator's
determination of the Fair Market Rent supported by the reasons therefor and
shall make counterpart copies for the other party appointed arbitrator and the
neutral arbitrator. The party appointed arbitrators shall arrange for a
simultaneous exchange of their proposed Fair Market Rent determinations. The
role of the neutral arbitrator shall be to select whichever of the two proposed
determinations of Fair Market Rent most closely approximates the neutral
arbitrator's own determination of Fair Market Rent. The neutral arbitrator shall
have no right to propose a middle ground or any modification of either of the
two proposed determinations of Fair Market Rent. The determination of Fair
Market Rent the neutral arbitrator chooses as that most closely approximating
the neutral arbitrator's determination of the Fair Market Rent shall constitute
the decision of the arbitrators and shall be final and binding upon the parties.
The arbitrators shall have no power to modify the provisions of this Lease.

         (4) The neutral arbitrator's decision shall be made not later than
thirty (30) days after the submission by the arbitrators of their proposals with
respect to the Fair Market Rent. The parties have included these time limits in
order to expedite the proceeding, but they are not jurisdictional, and the
neutral arbitrator may for good cause allow reasonable extensions or delays,
which shall not affect the validity of the decision. Absent fraud, collusion or
willful misconduct by the neutral arbitrator, the decision shall be final, and
judgment may be entered in any court having jurisdiction thereof.

         (5) Each party shall pay the fees and expenses of its respective
arbitrator and both parties shall share the fees and expenses of the neutral
arbitrator equally.

         (6) Notwithstanding any rights of Tenant to assign or sublet, the
option privilege granted herein shall not be assigned (except to an entity
affiliated or controlled by Tenant, or to CONVERA) under any circumstances
unless Landlord shall have consented to such assignment in writing, which
consent may be withheld by Landlord in its sole discretion.

         (7) Tenant Improvements shall remain in "As Is" condition.
