                                ASK JEEVES, INC.
                    Form of Debt Securities Warrant Agreement

      DEBT SECURITIES WARRANT AGREEMENT, dated as of ______________ between ASK
JEEVES, INC., a Delaware corporation (the "Company") and ____________, a
[corporation] [national banking association] organized and existing under the
laws of _____________and having a corporate trust office in ________, as warrant
agent (the "WARRANT AGENT").

      WHEREAS, the Company has entered into an indenture dated as of [
_________(the "SENIOR INDENTURE"), with _______________, as trustee (such
trustee, and any successors to such trustee, herein called the "SENIOR
TRUSTEE"), providing for the issuance from time to time of its unsubordinated
debt securities, to be issued in one or more series as provided in the Senior
Indenture (the "DEBT SECURITIES");] [ __________(the "SUBORDINATED INDENTURE"),
with ___________, as trustee (such trustee, and any successors to such trustee,
herein called the "SUBORDINATED TRUSTEE"), providing for the issuance from time
to time of its subordinated debt securities, to be issued in one or more series
as provided in the Subordinated Indenture (the "DEBT SECURITIES");]

      WHEREAS, the Company proposes to sell [If Warrants are sold with other
securities -- title of such other Securities being offered (the "OTHER
SECURITIES") with] warrant certificates evidencing one or more warrants (the
"WARRANTS" or, individually, a "WARRANT") representing the right to purchase
[title of Debt Securities purchasable through exercise of Warrants] (the
"WARRANT DEBT SECURITIES"), such warrant certificates and other warrant
certificates issued pursuant to this Agreement being herein called the "WARRANT
CERTIFICATES"; and

      WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing so to act, in connection with the
issuance, registration, transfer, exchange, exercise and replacement of the
Warrant Certificates, and in this Agreement wishes to set forth, among other
things, the form and provisions of the Warrant Certificates and the terms and
conditions on which they may be issued, registered, transferred, exchanged,
exercised and replaced;

      NOW, THEREFORE, in consideration of the premises and of the mutual
agreements herein contained, the parties hereto agree as follows:

                                    ARTICLE 1

                     ISSUANCE OF WARRANTS AND EXECUTION AND
                        DELIVERY OF WARRANT CERTIFICATES

      1.1   ISSUANCE OF WARRANTS. [If Warrants alone -- Upon issuance, each
Warrant Certificate shall evidence one or more Warrants.] [If Other Securities
and Warrants -- Warrant Certificates shall be [initially] issued in connection
with the issuance of the Other Securities [but shall be separately transferable
on and after _______________(the "DETACHABLE DATE")] [and shall not be
separately transferable] and each Warrant Certificate shall evidence one or more
Warrants.] Each Warrant evidenced thereby shall represent the right, subject to
the provisions contained herein and therein, to purchase one Warrant Debt
Security. [If Other Securities and

                                       1
<PAGE>

Warrants -- Warrant Certificates shall be initially issued in units with the
Other Securities and each Warrant Certificate included in such a unit shall
evidence _____________Warrants for each [$ ________________ principal amount]
[_______ shares] of Other Securities included in such unit.].

      1.2   EXECUTION AND DELIVERY OF WARRANT CERTIFICATES. Each Warrant
Certificate, whenever issued, shall be in registered form substantially in the
form set forth in Exhibit A hereto, shall be dated the date of its
countersignature by the Warrant Agent and may have such letters, numbers, or
other marks of identification or designation and such legends or endorsements
printed, lithographed or engraved thereon as the officers of the Company
executing the same may approve (execution thereof to be conclusive evidence of
such approval) and as are not inconsistent with the provisions of this
Agreement, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any
securities exchange on which the Warrants may be listed, or to conform to usage.
The Warrant Certificates shall be signed on behalf of the Company by any of its
present or future chief executive officers, presidents, senior vice presidents,
vice presidents, chief financial officers, chief legal officers, treasurers,
assistant treasurers, controllers, assistant controllers, secretaries or
assistant secretaries under its corporate seal reproduced thereon. Such
signatures may be manual or facsimile signatures of such authorized officers and
may be imprinted or otherwise reproduced on the Warrant Certificates. The seal
of the Company may be in the form of a facsimile thereof and may be impressed,
affixed, imprinted or otherwise reproduced on the Warrant Certificates.

      No Warrant Certificate shall be valid for any purpose, and no Warrant
evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the manual signature of the Warrant Agent. Such signature by
the Warrant Agent upon any Warrant Certificate executed by the Company shall be
conclusive evidence that the Warrant Certificate so countersigned has been duly
issued hereunder.

      In case any officer of the Company who shall have signed any of the
Warrant Certificates either manually or by facsimile signature shall cease to be
such officer before the Warrant Certificates so signed shall have been
countersigned and delivered by the Warrant Agent, such Warrant Certificates may
be countersigned and delivered notwithstanding that the person who signed
Warrant Certificates ceased to be such officer of the Company; and any Warrant
Certificate may be signed on behalf of the Company by such persons as, at the
actual date of the execution of such Warrant Certificate, shall be the proper
officers of the Company, although at the date of the execution of this Agreement
any such person was not such officer.

      The term "holder" or "holder of a Warrant Certificate" as used herein
shall mean any person in whose name at the time any Warrant Certificate shall be
registered upon the books to be maintained by the Warrant Agent for that purpose
[If Other Securities and Warrants are not immediately detachable -- or upon the
registration of the Other Securities prior to the Detachable Date. Prior to the
Detachable Date, the Company will, or will cause the registrar of the Other
Securities to, make available at all times to the Warrant Agent such information
as to holders of the Other Securities as may be necessary to keep the Warrant
Agent's records up to date].

      1.3   ISSUANCE OF WARRANT CERTIFICATES. Warrant Certificates evidencing
the right to purchase Warrant Debt Securities may be executed by the Company and
delivered to the Warrant Agent upon the execution of this Warrant Agreement or
from time to time thereafter. The Warrant Agent shall, upon receipt of Warrant
Certificates duly executed on behalf of the Company, countersign such Warrant
Certificates and shall deliver such Warrant Certificates to or upon the order of
the Company.

                                    ARTICLE 2

                           WARRANT PRICE, DURATION AND
                              EXERCISE OF WARRANTS

      2.1   WARRANT PRICE. During the period specified in Section 2.2, each
Warrant shall, subject to the terms of this Warrant Agreement and the applicable
Warrant Certificate, entitle the holder thereof, to purchase the principal
amount of Warrant Debt Securities specified in the applicable Warrant
Certificate at an initial exercise price of ________% of the principal amount
thereof [plus accrued amortization, if any, of the original issue discount of
the Warrant Debt Securities] [plus accrued interest, if any, from the most
recent date from which interest shall have been paid on the Warrant Debt
Securities or, if no interest shall have been paid on the Warrant Debt
Securities, from the date of their initial issuance.] [The original issue
discount ($ _______ for each $1,000 principal amount of Warrant Debt Securities)
will be amortized at a _______% annual rate, computed on a[n] [semi-] annual
basis [using a 360-day year consisting of twelve 30-day months].] Such purchase
price for the Warrant Debt Securities is referred to in this Agreement as the
"WARRANT PRICE."

      2.2   DURATION OF WARRANTS. Each Warrant may be exercised in whole or in
part at any time, as specified herein, on or after [the date thereof]
[__________] and at or before [______] p.m., [City] time, on ___________ or such
later date as the Company may designate by notice to the Warrant Agent and the
holders of Warrant Certificates mailed to their addresses as set forth in the
record books of the Warrant Agent (the "Expiration Date"). Each Warrant not
exercised at or before [__________] p.m., [City] time, on the Expiration Date
shall become void, and all rights of the holder of the Warrant Certificate
evidencing such Warrant under this Agreement shall cease.

      2.3   EXERCISE OF WARRANTS.

      (a)   During the period specified in Section 2.2, the Warrants may be
exercised to purchase a whole number of Warrant Debt Securities in registered
form by providing certain information as set forth on the reverse side of the
Warrant Certificate and by paying in full, in lawful money of the United States
of America, [in cash or by certified check or official bank check in New York
Clearing House funds] [by bank wire transfer in immediately available funds] the
Warrant Price for each Warrant Debt Security with respect to which a Warrant is
being exercised to the Warrant Agent at its corporate trust office, provided
that such exercise is subject to receipt within five business days of such
payment by the Warrant Agent of the Warrant Certificate with the form of
election to purchase Warrant Debt Securities set forth on the reverse side of
the Warrant Certificate properly completed and duly executed. The date on which
payment in full of the Warrant Price is received by the Warrant Agent shall,
subject to

                                       3
<PAGE>

receipt of the Warrant Certificate as aforesaid, be deemed to be the date on
which the Warrant is exercised; provided, however, that if, at the date of
receipt of such Warrant Certificates and payment in full of the Warrant Price,
the transfer books for the Warrant Debt Securities purchasable upon the exercise
of such Warrants shall be closed, no such receipt of such Warrant Certificates
and no such payment of such Warrant Price shall be effective to constitute the
person so designated to be named as the holder of record of such Warrant Debt
Securities on such date, but shall be effective to constitute such person as the
holder of record of such Warrant Debt Securities for all purposes at the opening
of business on the next succeeding day on which the transfer books for the
Warrant Debt Securities purchasable upon the exercise of such Warrants shall be
opened, and the certificates for the Warrant Debt Securities in respect of which
such Warrants are then exercised shall be issuable as of the date on such next
succeeding day on which the transfer books shall next be opened, and until such
date the Company shall be under no duty to deliver any certificate for such
Warrant Debt Securities. The Warrant Agent shall deposit all funds received by
it in payment of the Warrant Price in an account of the Company maintained with
it and shall advise the Company by telephone at the end of each day on which a
payment for the exercise of Warrants is received of the amount so deposited to
its account. The Warrant Agent shall promptly confirm such telephone advice to
the Company in writing.

      (b)   The Warrant Agent shall, from time to time, as promptly as
practicable, advise the Company of (i) the number of Warrant Debt Securities
with respect to which Warrants were exercised, (ii) the instructions of each
holder of the Warrant Certificates evidencing such Warrants with respect to
delivery of the Warrant Debt Securities to which such holder is entitled upon
such exercise, (iii) delivery of Warrant Certificates evidencing the balance, if
any, of the Warrants for the remaining Warrant Debt Securities after such
exercise, and (iv) such other information as the Company or the [Senior]
[Subordinated] Trustee shall reasonably require.

      (c)   As soon as practicable after the exercise of any Warrant, the
Company shall issue, pursuant to the Indenture, in authorized denominations, to
or upon the order of the holder of the Warrant Certificate evidencing such
Warrant, the Warrant Debt Securities to which such holder is entitled, in fully
registered form, registered in such name or names as may be directed by such
holder. If fewer than all of the Warrants evidenced by such Warrant Certificate
were exercised, the Company shall execute, and an authorized officer of the
Warrant Agent shall manually countersign and deliver, a new Warrant Certificate
evidencing Warrants for the number of Warrant Debt Securities remaining
unexercised.

      (d)   The Company shall not be required to pay any stamp or other tax or
other governmental charge required to be paid in connection with any transfer
involved in the issue of the Warrant Debt Securities, and in the event that any
such transfer is involved, the Company shall not be required to issue or deliver
any Warrant Debt Securities until such tax or other charge shall have been paid
or it has been established to the Company's satisfaction that no such tax or
other charge is due.

                                    ARTICLE 3

                     OTHER PROVISIONS RELATING TO RIGHTS OF
                         HOLDERS OF WARRANT CERTIFICATES

      3.1   NO RIGHTS AS HOLDERS OF WARRANT DEBT SECURITIES CONFERRED BY
WARRANTS OR WARRANT CERTIFICATES. No Warrant Certificate or Warrant evidenced
thereby shall entitle the holder thereof to any of the rights of a holder of
Warrant Debt Securities, including, without limitation, the right to receive the
payment of principal of (or premium, if any) or interest, if any, on the Warrant
Debt Securities or to enforce any of the covenants in the Indenture.

      3.2   LOST, STOLEN, MUTILATED OR DESTROYED WARRANT CERTIFICATES. Upon
receipt by the Warrant Agent of evidence reasonably satisfactory to it and the
Company of the ownership of and the loss, theft, destruction or mutilation of
any Warrant Certificate and/or indemnity reasonably satisfactory to the Warrant
Agent and the Company and, in the case of mutilation, upon surrender of the
mutilated Warrant Certificate to the Warrant Agent for cancellation, then, in
the absence of notice to the Company or the Warrant Agent that such Warrant
Certificate has been acquired by a bona fide purchaser, the Company shall
execute, and an authorized officer of the Warrant Agent shall manually
countersign and deliver, in exchange for or in lieu of the lost, stolen,
destroyed or mutilated Warrant Certificate, a new Warrant Certificate of the
same tenor and evidencing Warrants for a like principal amount of Warrant Debt
Securities. Upon the issuance of any new Warrant Certificate under this Section
3.2, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Warrant Agent) in connection
therewith. Every substitute Warrant Certificate executed and delivered pursuant
to this Section 3.2 in lieu of any lost, stolen or destroyed Warrant Certificate
shall represent an additional contractual obligation of the Company, whether or
not the lost, stolen or destroyed Warrant Certificate shall be at any time
enforceable by anyone, and shall be entitled to the benefits of this Agreement
equally and proportionately with any and all other Warrant Certificates duly
executed and delivered hereunder. The provisions of this Section 3.2 are
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement of mutilated, lost, stolen or destroyed
Warrant Certificates.

      3.3   HOLDER OF WARRANT CERTIFICATE MAY ENFORCE RIGHTS. Notwithstanding
any of the provisions of this Agreement, any holder of any Warrant Certificate,
without the consent of the Warrant Agent, the [Senior] [Subordinated] Trustee,
the holder of any Warrant Debt Securities or the holder of any other Warrant
Certificate, may, in such holder's own behalf and for such holder's own benefit,
enforce, and may institute and maintain any suit, action or proceeding against
the Company suitable to enforce, or otherwise in respect of, such holder's right
to exercise the Warrants evidenced by such holder's Warrant Certificate in the
manner provided in such holder's Warrant Certificates and in this Agreement.

      3.4   MERGER, SALE, CONVEYANCE OR LEASE. In case of (a) any share
exchange, merger or similar transaction of the Company with or into another
person or entity (other than a share exchange, merger or similar transaction in
which the Company is the acquiring or surviving corporation) or (b) the sale,
exchange, lease, transfer or other disposition of all or substantially all of
the properties and assets of the Company as an entirety (in any such case, a

                                       5
<PAGE>

"REORGANIZATION EVENT"), then, as a condition of such Reorganization Event,
lawful provisions shall be made, and duly executed documents evidencing the same
from the Company's successor shall be delivered to the holders of the Warrants,
so that such successor shall succeed to and be substituted for the Company, and
assume all the Company's obligations under, this Agreement and the Warrants. The
Company shall thereupon be relieved of any further obligation hereunder or under
the Warrants, and the Company as the predecessor corporation may thereupon or at
any time thereafter be dissolved, wound up or liquidated. Such successor or
assuming entity thereupon may cause to be signed, and may issue either in its
own name or in the name of the Company, any or all of the Warrants issuable
hereunder which heretofore shall not have been signed by the Company, and may
execute and deliver securities in its own name, in fulfillment of its
obligations to deliver Warrant Debt Securities upon exercise of the Warrants.
All the Warrants so issued shall in all respects have the same legal rank and
benefit under this Agreement as the Warrants theretofore or thereafter issued in
accordance with the terms of this Agreement as though all of such Warrants had
been issued at the date of the execution hereof. In any case of any such
Reorganization Event, such changes in phraseology and form (but not in
substance) may be made in the Warrants thereafter to be issued as may be
appropriate.

      The Warrant Agent may receive a written opinion of legal counsel as
conclusive evidence that any such Reorganization Event complies with the
provisions of this Section 3.4.

      3.5   NOTICE TO WARRANTHOLDERS. In case the Company shall (a) effect any
Reorganization Event or (b) make any distribution on or in respect of the [title
of Warrant Debt Securities] in connection with the dissolution, liquidation or
winding up of the Company, then the Company shall mail to each holder of
Warrants at such holder's address as it shall appear on the books of the Warrant
Agent, at least ten days prior to the applicable date hereinafter specified, a
notice stating the date on which such Reorganization Event, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of [title of Warrant Debt Securities] of
record shall be entitled to exchange their shares of [title of Warrant Debt
Securities] for securities or other property deliverable upon such
Reorganization Event, dissolution, liquidation or winding up. No failure to mail
such notice nor any defect therein or in the mailing thereof shall affect any
such transaction.

                                    ARTICLE 4

                  EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES

      4.1   EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES. [If Other Securities
with Warrants which are immediately detachable -- Upon] [If Other Securities
with Warrants which are not immediately detachable -- Prior to the Detachable
Date, a Warrant Certificate may be exchanged or transferred only together with
the Other Security to which the Warrant Certificate was initially attached, and
only for the purpose of effecting or in conjunction with an exchange or transfer
of such Other Security. Prior to any Detachable Date, each transfer of the Other
Security shall operate also to transfer the related Warrant Certificates. After
the Detachable Date, upon] surrender at the corporate trust office of the
Warrant Agent, Warrant Certificates evidencing Warrants may be exchanged for
Warrant Certificates in other denominations evidencing such Warrants or the
transfer thereof may be registered in whole or in part; provided that such other
Warrant Certificates evidence Warrants for the same aggregate principal amount

                                       6
<PAGE>

of Warrant Debt Securities as the Warrant Certificates so surrendered. The
Warrant Agent shall keep, at its corporate trust office, books in which, subject
to such reasonable regulations as it may prescribe, it shall register Warrant
Certificates and exchanges and transfers of outstanding Warrant Certificates,
upon surrender of the Warrant Certificates to the Warrant Agent at its corporate
trust office for exchange or registration of transfer, properly endorsed or
accompanied by appropriate instruments of registration of transfer and written
instructions for transfer, all in form satisfactory to the Company and the
Warrant Agent. No service charge shall be made for any exchange or registration
of transfer of Warrant Certificates, but the Company may require payment of a
sum sufficient to cover any stamp or other tax or other governmental charge that
may be imposed in connection with any such exchange or registration of transfer.
Whenever any Warrant Certificates are so surrendered for exchange or
registration of transfer, an authorized officer of the Warrant Agent shall
manually countersign and deliver to the person or persons entitled thereto a
Warrant Certificate or Warrant Certificates duly authorized and executed by the
Company, as so requested. The Warrant Agent shall not be required to effect any
exchange or registration of transfer which will result in the issuance of a
Warrant Certificate evidencing a Warrant for a fraction of a Warrant Debt
Security or a number of Warrants for a whole number of Warrant Debt Securities
and a fraction of a Warrant Debt Security. All Warrant Certificates issued upon
any exchange or registration of transfer of Warrant Certificates shall be the
valid obligations of the Company, evidencing the same obligations and entitled
to the same benefits under this Agreement as the Warrant Certificate surrendered
for such exchange or registration of transfer.

      4.2   TREATMENT OF HOLDERS OF WARRANT CERTIFICATES. [If Other Securities
and Warrants are not immediately detachable -- Prior to the Detachable Date, the
Company, the Warrant Agent and all other persons may treat the owner of the
Other Security as the owner of the Warrant Certificates initially attached
thereto for any purpose and as the person entitled to exercise the rights
represented by the Warrants evidenced by such Warrant Certificates, any notice
to the contrary notwithstanding. After the Detachable Date and prior to due
presentment of a Warrant Certificate for registration of transfer, the] [The]
Company, the Warrant Agent and all other persons may treat the registered holder
of a Warrant Certificate as the absolute owner thereof for any purpose and as
the person entitled to exercise the rights represented by the Warrants evidenced
thereby, any notice to the contrary notwithstanding.

      4.3   CANCELLATION OF WARRANT CERTIFICATES. Any Warrant Certificate
surrendered for exchange, registration of transfer or exercise of the Warrants
evidenced thereby shall, if surrendered to the Company, be delivered to the
Warrant Agent and all Warrant Certificates surrendered or so delivered to the
Warrant Agent shall be promptly canceled by the Warrant Agent and shall not be
reissued and, except as expressly permitted by this Agreement, no Warrant
Certificate shall be issued hereunder in exchange therefor or in lieu thereof.
The Warrant Agent shall deliver to the Company from time to time or otherwise
dispose of canceled Warrant Certificates in a manner satisfactory to the
Company.

accepting such appointment hereunder, and thereupon such successor Warrant
Agent, without any further act, deed or conveyance, shall become vested with all
the authority, rights, powers, trusts, immunities, duties and obligations of
such predecessor with like effect as if originally named as Warrant Agent
hereunder, and such predecessor, upon payment of its charges and disbursements
then unpaid, shall thereupon become obligated to transfer, deliver and pay over,
and such successor Warrant Agent shall be entitled to receive, all monies,
securities and other property on deposit with or held by such predecessor, as
Warrant Agent hereunder.
