                              AGREEMENT OF SUBLEASE

          This Agreement of Sublease (this "SUBLEASE") is made as of the 27th
day of July 2004 by and between RSA Security Inc., a Delaware corporation with
offices at 174 Middlesex Turnpike, Bedford, Massachusetts (hereinafter referred
to as "SUBLANDLORD"), and Ask Jeeves, Inc., a Delaware corporation with offices
at 5858 Horton Street, Suite 350, Emeryville, CA 94608 (hereinafter referred to
as "SUBTENANT").

                                   WITNESSETH:

          WHEREAS, pursuant to that certain Lease by and between Beacon
Properties, L.P., and assigned to MA-Crosby Corporate Center, L.L.C. (the "PRIME
LANDLORD") and Sublandlord (f/k/a Security Dynamics Technologies, Inc.) dated
March 11, 1996, as amended by a First Amendment to Lease dated May 10, 1997 and
by a Second Amendment to Lease dated April 8, 1998 and by a Third Amendment to
Lease dated May 9, 2000 (the "PRIME LEASE" a copy of which Prime Lease, redacted
as appropriate, is attached hereto as EXHIBIT A), Sublandlord has leased, inter
alia, space located at the Crosby Corporate Center, known in the Prime Lease as
Building 8, 34 Crosby Drive, Bedford, Massachusetts (the "BUILDING");

          WHEREAS, Subtenant desires to sublease from Sublandlord, and
Sublandlord desires to sublease to Subtenant, a portion of the premises leased
by Sublandlord in the Building as set forth below (hereinafter referred to as
the "DEMISED PREMISES"); and

          WHEREAS, the parties hereto desire to provide for the subletting of
the Demised Premises on the terms and conditions set forth in this Sublease.

          NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

          1. Demised Premises.  Subject to and contingent upon the written
consent of the Prime Landlord (the "Landlord Consent"), Sublandlord does hereby
sublease to Subtenant, and Subtenant does hereby sublease from Sublandlord, for
the term and upon the conditions hereinafter provided, the Demised Premises,
including the right to use all common areas relating to the Building as set
forth in the Prime Lease. The Demised Premises is agreed to be approximately
7,900 square feet of gross rentable area (the "RENTABLE AREA") on the second
floor of the Building, and is outlined on EXHIBIT B attached hereto and made a
part hereof.

          2. Condition of Demised Premises.

          Sublandlord shall deliver the Demised Premises in broom clean but
otherwise in its "as is" condition. Sublandlord shall not be required to make
any alterations, improvements, repairs or decorations to the Demised Premises,
and the Subtenant acknowledges that the provisions of Article 4 of the Prime
Lease, Article 6 of the First Amendment to the Prime Lease, Article 5 of the
Second Amendment to the Prime Lease, or any other provision requiring work to be
completed prior to occupancy of the Demised Premises are not applicable to this
Sublease. Subtenant's possession of the Demised Premises on the Commencement
Date (as defined

<PAGE>

hereafter) shall be conclusive evidence that the Demised Premises have been
delivered in accordance with the provisions of this Sublease and are acceptable
to Subtenant.

          Subtenant shall make no alterations, additions or improvements to the
Demised Premises without the prior written consent of Sublandlord and Prime
Landlord All alterations, additions or improvements to the Premises shall be
subject to the provisions of the Prime Lease. Notwithstanding the above,
Sublandlord acknowledges that the Prime Landlord shall undertake certain
alterations to the Demised Premises (the "Prime Landlord Alterations"), as set
forth in the Landlord Consent. Subtenant acknowledges that Sublandlord shall
have no responsibility for any costs or expenses with respect to either the
Prime Landlord Alterations or any restoration thereof.

          3. Term.

     The term of this Sublease shall commence on the later of (i) September 17,
2004 or (ii) the receipt of Prime Landlord's consent to this Sublease (the
"COMMENCEMENT DATE") and shall end at midnight on June 30, 2005, or on such
earlier date upon which said term may expire or be terminated pursuant to any of
the conditions or limitations or other provisions of this Sublease or pursuant
to law (the "TERM"). A Notice of Lease Commencement shall be executed by the
Subtenant within five (5) days of its delivery to the Subtenant by the
Sublandlord.

     Upon execution of this Sublease and receipt of written consent from the
Prime Landlord, Subtenant shall be allowed to enter the Demised Premises prior
to the Commencement Date solely for purposes of the Prime Landlord Alterations
(the "EARLY OCCUPANCY PERIOD"), subject to Subtenant's compliance with any
requirements of Prime Landlord. Subtenant's use of the Demised Premises during
the Early Occupancy Period shall be subject to all terms and conditions of this
Sublease except for the obligation to pay Base Rent. If, after obtaining Prime
Landlord's consent to this Sublease, Subtenant occupies the Demised Premises for
the purposes of conducting its business prior to September 17, 2004, then the
Early Occupancy Period shall terminate, and the Commencement Date shall be
deemed to be as of the date that Subtenant first occupied the Demised Premises
for the conduct of its business.

          4. Use.  Subtenant shall use and occupy the Demised Premises solely
for general office purposes, research, development, light manufacturing and any
uses ancillary thereto all in compliance with the Prime Lease, and shall comply
with all applicable laws, ordinances, governmental regulations, and all
protective covenants and restrictions of record affecting such use, and all
rules and regulations of the Prime Landlord with respect to the Building.

          5. Base Rent.  Commencing on the Commencement Date, Subtenant shall
pay base rent ("BASE RENT") for the Term hereby created in the monthly amount of
Six Thousand Five Hundred Eighty Three and 33/100 Dollars ($6,583.33).

     (The Base Rent and the Additional Rent (as defined hereafter) are referred
to herein as "RENT"). If the obligation of Subtenant to pay Base Rent hereunder
begins on a day other than on the first day of a month, Base Rent from such date
until the first day of the following month shall be pro-rated at the rate of
one-thirtieth (1/30) of the Base Rent for each day payable in


                                       2

<PAGE>

advance. Subtenant will pay said Base Rent by check made payable to Sublandlord
and sent to 174 Middlesex Turnpike, Bedford, Massachusetts, or to such other
party as Sublandlord may designate, at its address provided in the notice
section hereof, or at such other address as Sublandlord may hereafter designate
in writing, in lawful money of the United States, without notice, demand,
set-off or deduction whatsoever, except as otherwise provided in the Prime
Lease. Base Rent shall be due and payable on the first day of each month.

          6. Security Deposit.  (a) Simultaneously with the execution of this
Sublease, Subtenant shall provide Sublandlord with a Security Deposit (the
"Security Deposit") in the amount of Six Thousand Five Hundred Eighty Three and
33/100 Dollars ($6,583.33). Said Security Deposit may be mingled with other
funds of Sublandlord and no fiduciary relationship shall be created with respect
to such deposit, nor shall Sublandlord be liable to pay Subtenant interest
thereon. In the event that Subtenant is in default, beyond the expiration of any
applicable grace periods, of its obligations under this Sublease, then the
Sublandlord shall have the right, but not the obligation, at any time after such
event to (1) apply from said Security Deposit the amount necessary to cure such
default and/or (2) to exercise all rights and remedies Sublandlord may have on
account of such default and to apply from said Security Deposit the amount
which, in Sublandlord's reasonable opinion, is necessary to satisfy Subtenant's
liability on account thereof. In the event that Sublandlord elects to cure a
default by applying any portion of the Security Deposit, Subtenant shall, within
ten (10) business days of written demand therefor, replenish the Security
Deposit to the original amount. To the extent that Subtenant has faithfully
performed all of its covenants and obligations hereunder and is not otherwise in
default of its obligations under this Sublease as of the expiration or earlier
termination of this Sublease, Sublandlord shall return the Security Deposit to
Subtenant within ten (10) days after the Prime Landlord notified Sublandlord as
to whether any damage exists with respect to the Demised Premises.

          7. Additional Rent.

          Commencing at such time as the Early Occupancy Period begins, and
continuing during the term of this Sublease, Subtenant shall pay all electricity
charges and other utility charges with respect to the Demised Premises (which
payments, in addition to any other amounts due hereunder, are referred to as
"ADDITIONAL RENT"). Subtenant shall pay such charges within thirty (30) days of
receipt of billing from Sublandlord. Subtenant shall not be required to pay any
portion of the Operating Costs or Taxes (as those terms are defined in the Prime
Lease).

          8. Obligations Under the Prime Lease.  This Sublease and Subtenant's
rights under this Sublease shall at all times be subject to and are made upon
all of the terms, covenants, and conditions of the Prime Lease (except as
otherwise set forth herein), with the same force and effect as if fully set
forth herein at length, the termination (for whatever reason) of which Prime
Lease shall automatically terminate this Sublease upon notice to Subtenant.
Except as otherwise expressly provided for herein or as may be inconsistent or
in conflict with the terms and provisions of this Sublease, Subtenant shall
keep, observe and perform or cause to be kept, observed and performed,
faithfully all those terms, covenants and conditions of Sublandlord under the
Prime Lease with respect to the Demised Premises. Notwithstanding the foregoing,
where "Premises" or "Lease" or words of similar import appear in the Prime
Lease, the same shall be deemed to mean the Demised Premises (as defined in this
Sublease) and this Sublease,


                                       3

<PAGE>

respectively, and wherever the words "Landlord" and "Tenant" appear in the Prime
Lease, the words shall be deemed to refer to Sublandlord and Subtenant,
respectively.

          Notwithstanding the foregoing, to the extent that Sublandlord has any
rights or options to extend or renew the Prime Lease, or any expansion options
or right of first offers, Subtenant shall have no right to exercise such rights
or options. In addition, notwithstanding the provisions of this Section 8 of the
Sublease to the contrary, Sublandlord shall have no obligation to perform or
furnish any of the work, services, repairs or maintenance undertaken to be
provided to the Demised Premises that are made or performed by Prime Landlord
under the Lease (including but not limited to the Prime Landlord's Covenants set
forth in Article 8 of the Prime Lease), or any other term, covenant or condition
required to be performed by Prime Landlord under the Lease, and for all such
services and rights Subtenant will look solely to Prime Landlord. To the extent
that Sublandlord receives any abatement of Rent hereunder as a result of the
failure of Prime Landlord to perform or provide any of the work or services to
be provided by Prime Landlord in respect of the Demised Premises, Subtenant
shall receive a proportional abatement of its Rent due hereunder.

          9. Insurance.

               (a) Subtenant shall obtain and at all times during the term
hereof maintain, at its sole cost and expense, policies of insurance in the
amount and otherwise in conformance with the requirements of the Prime Lease.

               (b) Subtenant shall deliver to Sublandlord certificates of such
insurance at the beginning of the term of this Sublease, and thereafter
certificates of renewal thereof not less than fifteen (15) days prior to the
expiration of any such policy. In the event that Subtenant shall fail promptly
to furnish any insurance herein required, Sublandlord may effect the same and
pay the premium therefor for a period not exceeding one (1) year of the
expiration hereof, and the premium so paid by Sublandlord shall be payable by
Subtenant to Sublandlord within five (5) business days of receipt by Subtenant
of notice of payment thereof from Sublandlord.

               (c) All policies of insurance as aforesaid shall name both
Sublandlord and the Prime Landlord as additional insureds, as their interests
may appear, and include a clause waiving the rights of subrogation against Prime
Landlord and Sublandlord,

          10. Defaults.  If Subtenant shall (i) fail to pay when due any Rent or
other sums due hereunder, or (ii) shall fail to faithfully perform any other
obligation under this Sublease, or (iii) any other default under Article 21 of
the Prime Lease occurs, then Subtenant shall be in default of this Sublease and,
Sublandlord shall have all of the rights and remedies accorded to the Prime
Landlord under the Prime Lease. Subtenant further agrees to reimburse
Sublandlord for all costs and expenses, including reasonable attorneys' fees,
incurred by Sublandlord in asserting its rights hereunder against Subtenant or
any other party claiming by, through or under Subtenant.


                                       4

<PAGE>

          11. Subordination.  This Sublease is subject and subordinate to the
Prime Lease, to all ground and underlying leases, and to all mortgages and deeds
of trust which may now or hereafter affect such leases, the leasehold estate or
estates thereby created or the real property of which the Demised Premises form
a part, and to any and all renewals, modifications, consolidations, replacements
and extensions thereof

          12. Assignments and Further Subleases.

          (a) Subtenant agrees that it will not assign or encumber, or permit to
be encumbered, its rights or interests under this Sublease, nor sublet the whole
or any part of the Demised Premises, directly or indirectly, by operation of law
or otherwise, without the prior written consent of Sublandlord and Prime
Landlord. Sublandlord agrees that it shall not unreasonably withhold its consent
to any proposed assignment or sublet, provided that the proposed assignment or
sublet complies with all conditions set forth in the Prime Lease. Subtenant
further agrees that, notwithstanding any assignment or sublease, Subtenant shall
remain fully liable for the payment of Rent and Additional Rent and for the
other obligations of this Sublease on the part of Subtenant to be performed or
observed.

          (b) In the event Subtenant subleases or assigns all or part of the
Demised Premises to a tenant pursuant to Section 12 (a) above, and, after
deducting all reasonable expenses incurred by Subtenant in connection with such
sublease or assignment (including attorneys fees, brokerage commissions, tenant
improvements paid by Subtenant and rent concessions) said tenant is obligated to
pay Subtenant more in any month than Subtenant is obligated to pay Sublandlord
under this Sublease, then Subtenant shall pay Sublandlord one hundred percent
(100%) of the amount by which the said tenant's payment obligations exceed the
Subtenant's payment obligations hereunder.

          13. Quiet Enjoyment and Consent of Prime Landlord.  Sublandlord
covenants and agrees with Subtenant that, upon Subtenant paying the rent
reserved in this Sublease and observing and performing all the terms, covenants
and conditions of this Sublease on Subtenant's part to be observed and
performed, Subtenant may peaceably and quietly enjoy the Demised Premises during
the term of this Sublease free from any claim by Sublandlord or persons claiming
under Sublandlord, in accordance with the terms, covenants and conditions of
this Sublease.

          14. Indemnification.  Subtenant and Sublandlord shall be governed by
the terms of Article 15 of the Prime Lease with respect to each party's
indemnification of the other, provided, however, that Subtenant's indemnity
obligations thereunder shall run to both Sublandlord and the Prime Landlord.

          15. Notices.  Any notice, demand or other communication which must or
may be given or made by either party hereto shall be in writing and shall be
given or made by hand delivery, commercial courier, against receipt, or by
mailing the same by registered or certified mail, postage prepaid, addressed:

Premises.

          18. Sublandlord's Compliance with Prime Lease.  Sublandlord agrees to
pay all rents and other sums required of it, and comply with all other
provisions of the Prime Lease. Sublandlord hereby represents and warrants that
the Prime Lease (a) is presently in full force and effect, and has not been
amended or modified except as provided above, (b) there is presently no
outstanding default in the payment of rent or other sums due under the Prime
Lease and (c) to the best of Sublandlord's knowledge, there is presently no
outstanding breach or default of the Prime Lease by either Sublandlord or Prime
Landlord.

     Subtenant agrees that in any case where the provisions of this Sublease
require the consent or approval of Sublandlord prior to the taking of any
action, it shall be a condition precedent to the taking of such action that the
prior consent or approval of Prime Landlord shall have been obtained if Prime
Landlord' consent must be obtained under the Prime Lease in such cases. In the
event Prime Landlord's consent is so obtained, Sublandlord agrees that its
consent shall not be unreasonably withheld, delayed or conditioned except as
otherwise provided herein. Sublandlord agrees that it shall use commercially
reasonable efforts to obtain Prime Landlord's consent in such circumstances
(provided that in no event shall Sublandlord be required to compensate Prime
Landlord to obtain such consent), but otherwise shall not have any duty or
responsibility with respect to obtaining the consent or approval of Prime
Landlord.

          19. Casualty and Taking.  In the event of any taking by eminent domain
or damage by fire or other casualty to the Demised Premises thereby rendering
the Demised Premises wholly or in part untenantable, Subtenant shall acquiesce
in and be bound by any action taken by or agreement entered into between Prime
Landlord and Sublandlord as set forth in the Prime Lease with respect thereto.
In addition, in the event of any taking by eminent domain or damage by fire or
other casualty to the Demised Premises, Subtenant shall be entitled to exercise,
if applicable, the "Tenant's" termination rights set forth in 18.4(a), 18.4(b)
or 20.2 of the Prime Lease with respect to the Demised Premises, provided,
however, that it must provide notice of any such termination five (5) days
earlier than required by Sublandlord under the terms of the Prime Lease.

          20. Broker.  The parties warrant that they have had no dealings with
any broker or agent in connection with this Sublease except for T3 Realty
Advisors and Trammell Crow Company. Sublandlord and Subtenant each covenant to
pay, hold harmless and indemnify the other party from and against any and all
costs, expense or liability for any compensation, commissions and charges
claimed by and broker or agent other than the brokers designated in this Section
with respect to this Sublease or the negotiation thereof arising from a breach
of the foregoing warranty. Sublandlord shall be responsible for payment of any
brokerage commission to the broker designated in this Section pursuant to
separate agreement.
