                                ASK JEEVES, INC.
                    Form of Preferred Stock Warrant Agreement

      PREFERRED STOCK 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 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 Preferred Stock purchasable through exercise of Warrants] (the
"WARRANT 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--Warrants 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 Security. [If
Other Securities and 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

                                       1

<PAGE>

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 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 number of
Warrant Securities specified in the applicable Warrant Certificate at an initial
exercise price of $ __________ per Warrant Security, subject to adjustment upon
the occurrence of certain events, as hereinafter provided. Such purchase price
per Warrant Security 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 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 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 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 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 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 Securities on such date, but shall
be effective to constitute such person as the holder of record of such Warrant
Securities for all purposes at the opening of business on the next succeeding
day on which the transfer books for the Warrant Securities purchasable upon the
exercise of such Warrants shall be opened, and the certificates for the Warrant
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 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

                                       3

<PAGE>

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 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 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 Securities after such exercise, and (iv) such
other information as the Company shall reasonably require.

      (c)   As soon as practicable after the exercise of any Warrant, the
Company shall issue to or upon the order of the holder of the Warrant
Certificate evidencing such Warrant the Warrant 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 are 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 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 Securities, and in the event that any such
transfer is involved, the Company shall not be required to issue or deliver any
Warrant Security 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.

      (e)   Prior to the issuance of any Warrants there shall have been
reserved, and the Company shall at all times through the Expiration Date keep
reserved, out of its authorized but unissued Warrant Securities, a number of
shares sufficient to provide for the exercise of the Warrants.

                                   ARTICLE 3

                       OTHER PROVISIONS RELATING TO RIGHTS
                       OF HOLDERS OF WARRANT CERTIFICATES

      3.1   NO RIGHTS AS WARRANT SECURITYHOLDER 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 Securities,
including, without limitation, the right to receive the payment of dividends or
distributions, if any, on the Warrant Securities or to exercise any voting
rights, except to the extent expressly set forth in this Agreement or the
applicable Warrant Certificate.

      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

                                       4

<PAGE>

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 number of
Warrant 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 a Warrant Certificate,
without the consent of the Warrant Agent, the holder of any Warrant 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
Certificate and in this Agreement.

      3.4   ADJUSTMENTS.

      (a)   In case the Company shall at any time subdivide its outstanding
shares of [title of Preferred Stock purchasable through exercise of Warrants]
into a greater number of shares, the Warrant Price in effect immediately prior
to such subdivision shall be proportionately reduced and the number of Warrant
Securities purchasable under the Warrants shall be proportionately increased.
Conversely, in case the outstanding shares of [title of Preferred Stock
purchasable through exercise of Warrants] of the Company shall be combined into
a smaller number of shares, the Warrant Price in effect immediately prior to
such combination shall be proportionately increased and the number of Warrant
Securities purchasable under the Warrants shall be proportionately decreased.

      (b)   If at any time or from time to time the holders of [title of
Preferred Stock purchasable through exercise of Warrants] (or any shares of
stock or other securities at the time receivable upon the exercise of the
Warrants) shall have received or become entitled to receive, without payment
therefore,

            (i)   [title of Preferred Stock purchasable through exercise of
      Warrants] or any shares of stock or other securities which are at any time
      directly or indirectly convertible

                                       5

<PAGE>

      into or exchangeable for [title of Preferred Stock purchasable through
      exercise of Warrants], or any rights or options to subscribe for, purchase
      or otherwise acquire any of the foregoing by way of dividend or other
      distribution;

            (ii)  any cash paid or payable otherwise than in accordance with the
      terms of [title of Preferred Stock purchasable through exercise of
      Warrants] or otherwise than as a cash dividend paid or payable out of the
      Company's current or retained earnings;

            (iii) any evidence of the Company's indebtedness or rights to
      subscribe for or purchase the Company's indebtedness; or

            (iv)  [title of Preferred Stock purchasable through exercise of
      Warrants] or additional stock or other securities or property (including
      cash) by way of spinoff, split-up, reclassification, combination of shares
      or similar corporate rearrangement (other than shares of [title of
      Preferred Stock purchasable through exercise of Warrants] issued as a
      stock split or adjustments in respect of which shall be covered by the
      terms of Section 3.4(a) above),

then and in each such case, the holder of each Warrant shall, upon the exercise
of the Warrant, be entitled to receive, in addition to the number of Warrant
Securities receivable thereupon, and without payment of any additional
consideration therefore, the amount of stock and other securities and property
(including cash and indebtedness (or rights to subscribe for or purchase
indebtedness) which such holder would hold on the date of such exercise had he
been the holder of record of such Warrant Securities as of the date on which
holders of [title of Preferred Stock purchasable through exercise of Warrants]
received or became entitled to receive such shares or all other additional stock
and other securities and property.

      (c)   In case of (i) any reclassification, capital reorganization, or
change in the [title of Preferred Stock purchasable through the exercise of the
Warrants] of the Company (other than as a result of a subdivision, combination
or stock dividend provided for in Section 3.4(a) or Section 3.4(b) above), (ii)
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 and
which does not result in any change in the [title of Preferred Stock purchasable
through the exercise of the Warrants] other than the issuance of additional
shares of [title of Preferred Stock purchasable through the exercise of the
Warrants]) or (iii) 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 "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 or its successor shall be
delivered to the holders of the Warrants, so that the holders of the Warrants
shall have the right at any time prior to the expiration of the Warrants to
purchase, at a total price equal to that payable upon the exercise of the
Warrants, the kind and amount of shares of stock and other securities and
property receivable in connection with such Reorganization Event by a holder of
the same number of shares of [title of Preferred Stock purchasable through the
exercise of the Warrants] as were purchasable by the holders of the Warrants
immediately prior to such Reorganization Event. In any such case appropriate
provisions shall be made with respect to the rights and interests of the holders
of the Warrants so that the provisions hereof shall thereafter be

                                       6

<PAGE>

applicable with respect to any shares of stock or other securities and property
deliverable upon exercise the Warrants, and appropriate adjustments shall be
made to the Warrant Price payable hereunder provided the aggregate purchase
price shall remain the same. In the case of any transaction described in clauses
(ii) and (iii) above, 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 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.

      (d)   The Company may, at its option, at any time until the Expiration
Date, reduce the then current Warrant Price to any amount deemed appropriate by
the Board of Directors of the Company for any period not exceeding twenty
consecutive days (as evidenced in a resolution adopted by such Board of
Directors), but only upon giving the notices required by Section 3.5 at least
ten days prior to taking such action.

      (e)   Except as herein otherwise expressly provided, no adjustment in the
Warrant Price shall be made by reason of the issuance of any securities of the
Company or for any other reason whatsoever.

      (f)   No fractional Warrant Securities shall be issued upon the exercise
of Warrants. If more than one Warrant shall be exercised at one time by the same
holder, the number of full Warrant Securities which shall be issuable upon such
exercise shall be computed on the basis of the aggregate number of Warrant
Securities purchased pursuant to the Warrants so exercised. Instead of any
fractional Warrant Security which would otherwise be issuable upon exercise of
any Warrant, the Company shall pay a cash adjustment in respect of such fraction
in an amount equal to the same fraction of the last sales price (or bid price if
there were no sales) per Warrant Security, in either case as reported on the New
York Stock Exchange Composite Tape on the business day which next precedes the
day of exercise or, if the Warrant Securities are not then listed or admitted to

                  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

                                       9

<PAGE>

that such other Warrant Certificates evidence Warrants for the same aggregate
number of Warrant 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 Security or
a number of Warrants for a whole number of Warrant Securities and a fraction of
a Warrant 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] [T]he
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.

upon the terms and subject to the conditions herein set forth, and ____________
hereby accepts such appointment. The Warrant Agent shall have the powers and
authority granted to and conferred upon it in the Warrant Certificates and
hereby and such further powers and authority to act on behalf of the Company as
the Company may hereafter grant to or confer upon it. All of the terms and
provisions with respect to such powers and authority contained in the Warrant
Certificates are subject to and governed by the terms and provisions hereof.

hereunder of the holders from time to time of the Warrant Certificates shall be
subject:

      (a)   COMPENSATION AND INDEMNIFICATION. The Company agrees promptly to pay
the Warrant Agent the compensation to be agreed upon with the Company for all
services rendered by the Warrant Agent and to reimburse the Warrant Agent for
reasonable out-of-pocket expenses (including reasonable counsel fees) incurred

connection with the services rendered hereunder by the Warrant Agent. The
Company also agrees to indemnify the Warrant Agent for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, bad faith
or willful misconduct on the part of the Warrant Agent, arising out of or in
connection with its acting as Warrant Agent hereunder, including the reasonable
costs and expenses of defending against any claim of such liability.

      (b)   AGENT FOR THE COMPANY. In acting under this Warrant Agreement and in
connection with the Warrant Certificates, the Warrant Agent is acting solely as
agent of the Company and does not assume any obligations or relationship of
agency or trust for or with any of the holders of Warrant Certificates or
beneficial owners of Warrants.

      (c)   COUNSEL. The Warrant Agent may consult with counsel satisfactory to
it, which may include counsel for the Company, and the written advice of such
counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
accordance with the advice of such counsel.

      (d)   DOCUMENTS. The Warrant Agent shall be protected and shall incur no
liability for or in respect of any action taken or omitted by it in reliance
upon any Warrant Certificate, notice, direction, consent, certificate,
affidavit, statement or other paper or document reasonably believed by it to be
genuine and to have been presented or signed by the proper parties.

      (e)   CERTAIN TRANSACTIONS. The Warrant Agent, and its officers, directors
and employees, may become the owner of, or acquire any interest in, Warrants,
with the same rights that it or they would have if it were not the Warrant Agent
hereunder, and, to the extent

                                       11

<PAGE>

permitted by applicable law, it or they may engage or be interested in any
financial or other transaction with the Company and may act on, or as
depositary, trustee or agent for, any committee or body of holders of Warrant
Securities or other obligations of the Company as freely as if it were not the
Warrant Agent hereunder. Nothing in this Warrant Agreement shall be deemed to
prevent the Warrant Agent from acting as trustee under any indenture to which
the Company is a party.

      (f)   NO LIABILITY FOR INTEREST. Unless otherwise agreed with the Company,
the Warrant Agent shall have no liability for interest on any monies at any time
received by it pursuant to any of the provisions of this Agreement or of the

perform only such duties as are herein and in the Warrant Certificates

this Agreement or the Warrant Certificates against the Warrant Agent. The
Warrant Agent shall not be under any obligation to take any action hereunder
which may tend to involve it in any expense or liability, the payment of which
within a reasonable time is not, in its reasonable opinion, assured to it. The
Warrant Agent shall not be accountable or under any duty or responsibility for
the use by the Company of any of the Warrant Certificates authenticated by the
Warrant Agent and delivered by it to the Company pursuant to this Agreement or
for the application by the Company of the proceeds of the Warrant Certificates.
The Warrant Agent shall have no duty or responsibility in case of any default by
the Company in the performance of its covenants or agreements contained herein
or in the Warrant Certificates or in the case of the receipt of any written
demand from a holder of a Warrant Certificate with respect to such default,
including, without limiting the generality of the foregoing, any duty or
responsibility to initiate or attempt to initiate any proceedings at law or
otherwise or, except as provided in Section 6.2 hereof, to make any demand upon
the Company.

jurisdiction of its organization to exercise corporate trust powers) and the
acceptance of such appointment by such successor Warrant Agent. The obligation
of the Company under Section 5.2(a) shall continue to the extent set forth
therein notwithstanding the resignation or removal of the Warrant Agent.

the Warrant Agent shall cease to be Warrant Agent hereunder.

      (d)   Any successor Warrant Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor and to the Company an instrument
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.
