                    AGREEMENT CONCERNING ADDITIONAL INVESTORS

        This AGREEMENT CONCERNING ADDITIONAL INVESTORS (the "Agreement") is made
and entered into as of March 8, 2002 by and among Superconductor Technologies
Inc., a Delaware corporation (the "Company"), and each of the investors set
forth on the signature pages of this Agreement (the "Investors") with reference
to the following facts:

        A. The Company and the Investors are parties to that certain Securities
Purchase Agreement dated as of March 6, 2002 (the "Securities Purchase
Agreement") concerning the sale to the Investors of (i) an aggregate of
3,714,286 shares (the "Shares") of the Company's common stock, par value $0.001
per share ("Common Stock"), at $3.50 per share and (ii) stock purchase warrants
in the form attached to the Agreement (the "Warrants") to purchase up to 557,143
additional shares of Common Stock (the "Warrant Shares"). (The Warrants and
Warrant Shares collectively, the "Securities".)

        B. The Company has received commitments to date from the Investors to
purchase 3,200,285 Shares and Warrants to purchase 480,043 Warrant Shares. The
Company is pursuing commitments from several additional investors (the
"Additional Investors") for the remaining 514,238 Shares and Warrants to
purchase 77,143 Warrant Shares and awaiting written confirmation from Nasdaq
that participation of the Additional Investors will not require approval of the
Company's shareholders under Nasdaq's Marketplace Rules.

        C. The Company plans to hold a first Closing on the commitments received
to date from the Investors as soon as practicable and, subject to receipt of the
aforementioned written confirmation from Nasdaq, to hold a second Closing on any
further commitments to purchase any of the remaining Securities received on or
before March 15, 2002 as soon as practicable after such date.

        D. Capitalized terms not defined in this Agreement have the meanings
given to them in the Securities Purchase Agreement.

        NOW, THEREFORE, the Company and each of the Investors severally (and not
jointly) hereby agree as follows:

        1. First Closing for Existing Investors. The Closing for the commitments
received to date from the Investors shall occur on Monday, March 11, 2002 at the
offices of Guth|Christopher LLP at 10866 Wilshire Blvd., Suite 1250, Los
Angeles, California 90024. The Investors hereby waive any condition to the
Closing that the Company have secured purchasers for all of the Securities and
agree to Close the transactions based on the commitments received to date from
the Investors.

        2. Second Closing for Any Additional Investors. Subject to written
confirmation from Nasdaq that the sale of the remaining Securities to Additional
Investors will not require approval of the Company's shareholders under Nasdaq's
Marketplace Rules, the Company will hold a second Closing for any further
commitments to purchase additional Securities received from Additional Investors
by Friday, March 15, 2002. The Company will hold the second Closing as soon as
practicable after such date at the offices of Guth|Christopher LLP at 10866
Wilshire Blvd., Suite 1250, Los Angeles, California 90024. The Company may not
issue in the

aggregate in the first and second Closing more Securities than contemplated
under the Securities Purchase Agreement, and the Company may elect to decline to
sell any additional Securities if it has not received the aforementioned written
confirmation from Nasdaq within a reasonable period of time as determined by the
Company in its sole discretion.

               2.1 General. Except as expressly modified herein, the Securities
Purchase Agreement shall remain in full force and effect, and to the extent
reasonably applicable, the provisions of Section 7 thereof (Governing Law;
Miscellaneous) are hereby incorporated herein and made a part hereof. This

<PAGE>

               Agreement, dated as of March 20, 2002, between Overture Services,
Inc., a Delaware corporation (the "Company"), and Mellon Investor Services LLC,
a New Jersey limited liability company, as rights agent (the "Rights Agent").

               The Board of Directors of the Company has authorized and declared
a dividend of one preferred share purchase right (a "Right") for each Common
Share (as hereinafter defined) of the Company outstanding on March 29, 2002 (the
"Record Date"), each Right representing the right to purchase one one-hundredth
of a Preferred Share (as hereinafter defined), upon the terms and subject to the
conditions herein set forth, and has further authorized and directed the
issuance of one Right with respect to each Common Share that shall become
outstanding between the Record Date and the earliest of the Distribution Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined).

               Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

               Section 1. Definitions. For purposes of this Agreement, the
following terms have the meanings indicated:

               (a) "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the Common Shares of the Company then
outstanding, but shall not include the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any Subsidiary of the Company, or
any Person holding Common Shares for or pursuant to the terms of any such plan.
Notwithstanding the foregoing, no Person shall become an "Acquiring Person" as
the result of an acquisition of Common Shares by the Company which, by reducing
the number of Common

<PAGE>

Shares of the Company outstanding, increases the proportionate number of Common
Shares of the Company beneficially owned by such Person to 15% or more of the
Common Shares of the Company then outstanding; provided, however, that, if a
Person shall become the Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding by reason of share purchases by the Company and
shall, after such share purchases by the Company, become the Beneficial Owner of
any additional Common Shares of the Company, then such Person shall be deemed to
be an "Acquiring Person." Notwithstanding the foregoing, if the Board of
Directors of the Company determines in good faith that a Person who would
otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently, and such Person
divests as promptly as practicable a sufficient number of Common Shares so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), then such Person shall not be deemed
to be an "Acquiring Person" for any purposes of this Agreement.

               (b) "Affiliate" shall have the meaning ascribed to such term in
Rule 12b-2 of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement.

               (c) "Associate" shall have the meaning ascribed to such term in
Rule 12b-2 of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement.

               (d) A Person shall be deemed the "Beneficial Owner" of and shall
be deemed to "beneficially own" any securities:

                                      -2-
<PAGE>

               (i) which such Person or any of such Person's Affiliates or
        Associates beneficially owns, directly or indirectly;

               (ii) which such Person or any of such Person's Affiliates or
        Associates has (A) the right to acquire (whether such right is
        exercisable immediately or only after the passage of time) pursuant to
        any agreement, arrangement or understanding (other than customary
        agreements with and between underwriters and selling group members with
        respect to a bona fide public offering of securities), or upon the
        exercise of conversion rights, exchange rights, rights (other than these
        Rights), warrants or options, or otherwise; provided, however, that a
        Person shall not be deemed the Beneficial Owner of, or to beneficially
        own, securities tendered pursuant to a tender or exchange offer made by
        or on behalf of such Person or any of such Person's Affiliates or
        Associates until such tendered securities are accepted for purchase or
        exchange; or (B) the right to vote pursuant to any agreement,
        arrangement or understanding; provided, however, that a Person shall not
        be deemed the Beneficial Owner of, or to beneficially own, any security
        if the agreement, arrangement or understanding to vote such security (1)
        arises solely from a revocable proxy or consent given to such Person in
        response to a public proxy or consent solicitation made pursuant to, and
        in accordance with, the applicable rules and regulations promulgated
        under the Exchange Act and (2) is not also then reportable on Schedule
        13D under the Exchange Act (or any comparable or successor report); or

               (iii) which are beneficially owned, directly or indirectly, by
        any other Person with which such Person or any of such Person's
        Affiliates or Associates has any agreement, arrangement or understanding
        (other than customary agreements with and between underwriters and
        selling group members with respect to a bona fide public offering of se

                                      -3-

        curities) for the purpose of acquiring, holding, voting (except to the
        extent contemplated by the proviso to Section 1(d)(ii)(B) hereof) or
        disposing of any securities of the Company.

               Notwithstanding anything in this definition of Beneficial Owner
to the contrary, the phrase "then outstanding," when used with reference to a
Person's beneficial ownership of securities of the Company, shall mean the
number of such securities then issued and outstanding together with the number
of such securities not then actually issued and outstanding which such Person
would be deemed to own beneficially hereunder.

               (e) "Business Day" shall mean any day other than a Saturday, a
Sunday, or a day on which banking institutions in the States of California or
New Jersey are authorized or obligated by law or executive order to close.

               (f) "Close of Business" on any given date shall mean 5:00 P.M.,
California time, on such date; provided, however, that, if such date is not a
Business Day, it shall mean 5:00 P.M., California time, on the next succeeding
Business Day.

               (g) "Common Shares" when used with reference to the Company shall
mean the shares of common stock, par value $0.0001 per share, of the Company.
"Common Shares" when used with reference to any Person other than the Company
shall mean the capital stock (or equity interest) with the greatest voting power
of such other Person or, if such other Person is a Subsidiary of another Person,
the Person or Persons which ultimately control such first-mentioned Person.

               Section 3. Issue of Right Certificates. (a) Until the earlier of

Subsidiary of the Company or any entity holding Common Shares of the Company for
or pursuant to the terms of any such plan) of a tender or exchange offer the

Common Shares of the Company (including any such date which is after the date of
this Agreement and prior to the issuance of the Rights; the earlier of such
dates being herein referred to as the "Distribution Date"), (x) the Rights will
be evidenced (subject to the provisions of Section 3(b) hereof) by the
certificates for Common Shares of the Company registered in the names of the
holders thereof (which certificates shall also be deemed to be Right
Certificates) and not by separate Right Certificates, and (y) the right to
receive Right Certificates will be transferable only in connection with the
transfer of Common Shares of the Company. The Company shall promptly notify the
Rights Agent of the occurrence of a Distribution Date and, if such notification

Date has not yet occurred. As soon as practicable after the Rights Agent
receives written notice of a Distribution Date, the Company will prepare and
execute, the Rights Agent will countersign,

                                      -7-
<PAGE>

and the Company will send or cause to be sent (and the Rights Agent will, if
requested and provided with all necessary information (including the addresses
shown on the records of the Company of record holders of Common Shares of the
Company as of the Close of Business on the Distribution Date) send) by
first-class, insured, postage-prepaid mail, to each record holder of Common
Shares of the Company as of the Close of Business on the Distribution Date, at
the address of such holder shown on the records of the Company, a Right
Certificate, in substantially the form of Exhibit B hereto (a "Right
Certificate"), evidencing one Right for each Common Share so held. As of and
after the Distribution Date, the Rights will be evidenced solely by such Right
Certificates.

               (b) On the Record Date, or as soon as practicable thereafter, the
Company will send a copy of a Summary of Rights to Purchase Preferred Shares, in
substantially the form of Exhibit C hereto (the "Summary of Rights"), by
first-class, postage-prepaid mail, to each record holder of Common Shares as of
the Close of Business on the Record Date, at the address of such holder shown on
the records of the Company. With respect to certificates for Common Shares of
the Company outstanding as of the Record Date, until the Distribution Date, the
Rights will be evidenced by such certificates registered in the names of the
holders thereof together with a copy of the Summary of Rights attached thereto.
Until the Distribution Date (or the earlier of the Redemption Date or the Final
Expiration Date), the surrender for transfer of any certificate for Common
Shares of the Company outstanding on the Record Date, with or without a copy of
the Summary of Rights attached thereto, shall also constitute the transfer of
the Rights associated with the Common Shares of the Company represented thereby.

               (c) Certificates for Common Shares which become outstanding
(including, without limitation, reacquired Common Shares referred to in the last
sentence of this paragraph

                                      -8-
<PAGE>

(c)) after the Record Date but prior to the earliest of the Distribution Date,
the Redemption Date or the Final Expiration Date shall have impressed on,
printed on, written on or otherwise affixed to them the following legend:

        This certificate also evidences and entitles the holder hereof to
        certain rights as set forth in a Rights Agreement between Overture
        Services, Inc. and Mellon Investor Services LLC, as Rights Agent, dated
        as of March 15, 2002, as it may be amended from time to time (the
        "Agreement"), the terms of which are hereby incorporated herein by
        reference and a copy of which is on file at the principal executive
        offices of Overture Services, Inc. Under certain circumstances, as set
        forth in the Agreement, such Rights (as defined in the Agreement) will
        be evidenced by separate certificates and will no longer be evidenced by
        this certificate. Overture Services, Inc. will mail to the holder of
        this certificate a copy of the Agreement without charge after receipt of
        a written request therefor. As set forth in the Agreement, Rights
        beneficially owned by any Person (as defined in the Agreement) who
        becomes an Acquiring Person (as defined in the Agreement) become null
        and void.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares of the Company
represented by such certificates shall be evidenced by such certificates alone,
and the surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares of the Company
represented thereby. In the event that the Company purchases or acquires any
Common Shares of the Company after the Record Date but prior to the Distribution
Date, any Rights associated with such Common Shares of the Company shall be
deemed cancelled and retired so that the Company shall not be entitled to
exercise any Rights associated with the Common Shares of the Company which are
no longer outstanding.

               Section 4. Form of Right Certificates. The Right Certificates
(and the forms of election to purchase Preferred Shares and of assignment to be
printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto, and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and which do not affect the rights, duties or responsibilities of
the Rights

                                      -9-
<PAGE>

Agent and as are not inconsistent with the provisions of this Agreement, or as
may be required to comply with any applicable law or with any applicable rule or
regulation made pursuant thereto or with any applicable rule or regulation of
any stock exchange or the National Association of Securities Dealers, Inc., or
to conform to usage. Subject to the provisions of Section 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such number of one
one-hundredths of a Preferred Share as shall be set forth therein at the price
per one one-hundredth of a Preferred Share set forth therein (the "Purchase
Price"), but the number of such one one-hundredths of a Preferred Share and the
Purchase Price shall be subject to adjustment as provided herein.

               Section 5. Countersignature and Registration. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its Chief Executive Officer, its President, any of its Vice Presidents or
its Treasurer, either manually or by facsimile signature, shall have affixed
thereto the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be manually countersigned by
the Rights Agent and shall not be valid for any purpose unless countersigned. In
case any officer of the Company who shall have signed any of the Right
Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the individual who signed such Right Certificates had not ceased to be such
officer of the Company; and any Right Certificate may be signed on behalf of the
Company by any individual who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Company to sign such Right
Certificate, al-

                                      -10-
<PAGE>

though at the date of the execution of this Agreement any such individual was
not such an officer.

               Following the Distribution Date and receipt by the Rights Agent
of the notice and all other relevant information referred to in Section 3(a),
the Rights Agent will keep or cause to be kept, at its office, designated for
such purpose, books for registration and transfer of the Right Certificates
issued hereunder. Such books shall show the names and addresses of the
respective holders of the Right Certificates, the number of Rights evidenced on
its face by each of the Right Certificates and the date of each of the Right
Certificates.

               Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. Subject
to the provisions of Section 14 hereof, at any time after the Close of Business
on the Distribution Date, and at or prior to the Close of Business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become null and void pursuant to Section 11(a)(ii) hereof or
that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Right Certificate or Right
Certificates entitling the registered holder to purchase a like number of one
one-hundredths of a Preferred Share as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any Right Certificate
or Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose. Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered Right Certificate or Right Cer-

                                      -11-
<PAGE>

tificates until the registered holder shall have properly completed and signed
the certificate contained in the form of assignment on the reverse side of such
Right Certificate or Right Certificates and shall have provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company or the Rights Agent shall
reasonably request. Thereupon the Rights Agent shall countersign and deliver to
the Person entitled thereto a Right Certificate or Right Certificates, as the
case may be, as so requested. The Company may require payment from the holders
of Right Certificates of a sum sufficient to cover any tax or governmental
charge that may be imposed in connection with any transfer, split up,
combination or exchange of Right Certificates. The Rights Agent shall have no
duty or obligation under this Section 6 or any other similar provision of this
Agreement unless and until it is reasonably satisfied that all such taxes and
governmental charges have been paid in full.

               Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's or Rights
Agent's request, reimbursement to the Company and the Rights Agent of all
reasonable expenses incidental thereto, and upon surrender to the Rights Agent
and cancellation of the Right Certificate if mutilated, the Company will make
and deliver a new Right Certificate of like tenor to the Rights Agent for
countersignature and delivery to the registered holder in lieu of the Right
Certificate so lost, stolen, destroyed or mutilated.

               Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights. (a) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein), in whole or in
part, at any time after the Distribution Date, upon

                                      -12-
<PAGE>

surrender of the Right Certificate, with the form of election to purchase on the
reverse side thereof properly completed and duly executed, to the Rights Agent
at the office of the Rights Agent designated for such purpose, together with
payment of the Purchase Price for each one one-hundredth of a Preferred Share as
to which the Rights are exercised, at or prior to the earliest of (i) the Close
of Business on March 29, 2012 (the "Final Expiration Date"), (ii) the time at
which the Rights are redeemed as provided in Section 23 hereof (the "Redemption
Date"), or (iii) the time at which such Rights are exchanged as provided in
Section 24 hereof.

               (b) The Purchase Price for each one one-hundredth of a Preferred
Share purchasable pursuant to the exercise of a Right shall initially be $200,
and shall be subject to adjustment from time to time as provided in Section 11
or 13 hereof, and shall be payable in lawful money of the United States of
America in accordance with paragraph (c) below.

               (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed and properly
completed, accompanied by payment of the Purchase Price for the shares to be
purchased and an amount equal to any applicable transfer or like tax or
governmental charge required to be paid by the holder of such Right Certificate
in accordance with Section 9 hereof by certified check, cashier's check or money
order payable to the order of the Company, the Rights Agent shall thereupon
promptly (i) (A) requisition from any transfer agent of the Preferred Shares
certificates for the number of Preferred Shares to be purchased and the Company
hereby irrevocably authorizes any such transfer agent to comply with all such
requests, or (B) requisition from the depositary agent depositary receipts
representing such number of one one-hundredths of a Preferred Share as are to be
purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent of the Preferred Shares
with such depositary agent) and the Company

                                      -13-
<PAGE>

hereby directs such depositary agent to comply with such request; (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of issuance of fractional shares in accordance with Section 14 hereof; (iii)
promptly after receipt of such certificates or depositary receipts, cause the
same to be delivered to or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be designated by such
holder; and (iv) when appropriate, after receipt, promptly deliver such cash to
or upon the order of the registered holder of such Right Certificate.

               (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Right Certificate or to
such holder's duly authorized assigns, subject to the provisions of Sections 6
and 14 hereof.

               Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Agreement. The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all cancelled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such cancelled Right Certificates, and, in such
case, shall deliver a certificate of destruction thereof to the Company.

                                      -14-
<PAGE>

               Section 9. Availability of Preferred Shares. The Company
covenants and agrees that it will cause to be reserved and kept available out of
its authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance with Section 7 hereof.
The Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares delivered upon exercise of Rights
shall, at the time of delivery of the certificates for such Preferred Shares
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares.

               The Company further covenants and agrees that it will pay when
due and payable any and all taxes and governmental charges payable by the
Company in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares upon the exercise of Rights. The Company shall not,
however, be required to pay any tax or governmental charge which may be payable
in respect of any transfer or delivery of Right Certificates to a Person other
than, or the issuance or delivery of certificates or depositary receipts for the
Preferred Shares in a name other than that of, the registered holder of the
Right Certificate evidencing Rights surrendered for exercise or to issue or to
deliver any certificates or depositary receipts for Preferred Shares upon the
exercise of any Rights until any such transfer or like tax or governmental
charge shall have been paid (any such tax or charge being payable by the holder
of such Right Certificate at the time of surrender) or until it has been
established to the Company's reasonable satisfaction that no such tax or
governmental charge is due.

               Section 10. Preferred Shares Record Date. Each Person in whose
name any certificate for Preferred Shares is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of the
Preferred Shares represented thereby on, and

                                      -15-
<PAGE>

such certificate shall be dated, the date upon which the Right Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer or like taxes and governmental charges) was made;
provided, however, that, if the date of such surrender and payment is a date
upon which the Preferred Shares transfer books of the Company are closed, such
Person shall be deemed to have become the record holder of such shares on, and
such certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares transfer books of the Company are open. Prior to the exercise
of the Rights evidenced thereby, the holder of a Right Certificate shall not be
entitled to any rights of a holder of Preferred Shares for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

               Section 11. Adjustment of Purchase Price, Number of Shares or
Number of Rights. The Purchase Price, the number of Preferred Shares covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

               (a) (i) In the event the Company shall at any time after the date
of this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification,

                                      -16-
<PAGE>

and the number and kind of shares of capital stock issuable on such date, shall
be proportionately adjusted so that the holder of any Right exercised after such
time shall be entitled to receive the aggregate number and kind of shares of
capital stock which, if such Right had been exercised immediately prior to such
date and at a time when the Preferred Shares transfer books of the Company were
open, such holder would have owned upon such exercise and been entitled to
receive by virtue of such dividend, subdivision, combination or
reclassification; provided, however, that in no event shall the consideration to
be paid upon the exercise of one Right be less than the aggregate par value of
the shares of capital stock of the Company issuable upon exercise of one Right.

               (ii) Subject to Section 24 hereof, in the event any Person
becomes an Acquiring Person, each holder of a Right shall thereafter have a
right to receive, upon exercise thereof at a price equal to the then current
Purchase Price multiplied by the number of one one-hundredths of a Preferred
Share for which a Right is then exercisable, in accordance with the terms of
this Agreement and in lieu of Preferred Shares, such number of Common Shares of
the Company as shall equal the result obtained by (A) multiplying the then
current Purchase Price by the number of one one-hundredths of a Preferred Share
for which a Right is then exercisable and dividing that product by (B) 50% of
the then current per share market price of the Common Shares of the Company
(determined pursuant to Section 11(d) hereof) on the date of the occurrence of
such event. In the event that any Person shall become an Acquiring Person and
the Rights shall then be outstanding, the Company shall not take any action
which would eliminate or diminish the benefits intended to be afforded by the
Rights.

               From and after the occurrence of such event, any Rights that are
or were acquired or beneficially owned by any Acquiring Person (or any Associate
or Affiliate of such Acquiring

                                      -17-
<PAGE>

Person) shall be null and void without any further action, and any holder of
such Rights shall thereafter have no right to exercise such Rights under any
provision of this Agreement. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person whose Rights would be null and void pursuant to the preceding sentence or
any Associate or Affiliate or nominee thereof; no Right Certificate shall be
issued at any time upon the transfer of any Rights to an Acquiring Person whose
Rights would be null and void pursuant to the preceding sentence or any
Associate or Affiliate thereof or to any nominee of such Acquiring Person,
Associate or Affiliate; and any Right Certificate delivered to the Rights Agent
for transfer to an Acquiring Person whose Rights would be null and void pursuant
to the preceding sentence shall be cancelled. The Company shall give the Rights
Agent written notice of the identity of any such Acquiring Person, Associate or
Affiliate, or the nominee of any of the foregoing, and the Rights Agent may rely
on such notice in carrying out its duties under this Agreement and shall be
deemed not to have any knowledge of the identity of any such Acquiring Person,
Associate or Affiliate, or the nominee of any of the foregoing unless and until
it shall have received such notice.

               (iii) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit the
exercise in full of the Rights in accordance with subparagraph (ii) above, the
Company shall take all such action as may be necessary to authorize additional
Common Shares for issuance upon exercise of the Rights. In the event the Company
shall, after good faith effort, be unable to take all such action as may be
necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exercise
of a Right, a number of Preferred Shares or fraction thereof such that the
current per share market price of one Preferred Share multiplied by

                                      -18-
<PAGE>

such number or fraction is equal to the current per share market price of one
Common Share as of the date of issuance of such Preferred Shares or fraction
thereof. The Company shall provide the Rights Agent written notice of any
substitution made pursuant to this Section 11(a)(iii).

               (b) In case the Company shall fix a record date for the issuance
of rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current per
share market price of the Preferred Shares (as defined in Section 11(d) hereof)
on such record date, the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of Preferred Shares outstanding on such record date plus the number of
Preferred Shares which the aggregate offering price of the total number of
Preferred Shares and/or equivalent preferred shares so to be offered (and/or the
aggregate initial conversion price of the convertible securities so to be
offered) would purchase at such current market price and the denominator of
which shall be the number of Preferred Shares outstanding on such record date
plus the number of additional Preferred Shares and/or equivalent preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible); provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right. In case such subscription price may be paid
in a

                                      -19-
<PAGE>

consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be conclusive and binding on the Rights
Agent and holders of the Rights. Preferred Shares owned by or held for the
account of the Company shall not be deemed outstanding for the purpose of any
such computation. Such adjustment shall be made successively whenever such a
record date is fixed; and, in the event that such rights, options or warrants
are not so issued, the Purchase Price shall be adjusted to be the Purchase Price
which would then be in effect if such record date had not been fixed.

               (c) In case the Company shall fix a record date for the making of
a distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the then-current per share market price of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive and binding on the
Rights Agent and holders of the Rights) of the portion of the assets or
evidences of indebtedness so to be distributed or of such subscription rights or
warrants applicable to one Preferred Share and the denominator of which shall be
such then-current per share market price of the Preferred Shares on such record
date;

                                      -20-
<PAGE>

provided, however, that in no event shall the consideration to be paid upon the
exercise of one Right be less than the aggregate par value of the shares of
capital stock of the Company to be issued upon exercise of one Right. Such
adjustments shall be made successively whenever such a record date is fixed;
and, in the event that such distribution is not so made, the Purchase Price
shall again be adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.

               (d) (i) For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the 30 consecutive Trading
Days (as hereinafter defined) immediately prior to such date; provided, however,
that, in the event that the current per share market price of the Security is
determined during a period following the announcement by the issuer of such
Security of (A) a dividend or distribution on such Security payable in shares of
such Security or Securities convertible into such shares, or (B) any
subdivision, combination or reclassification of such Security and prior to the
expiration of 30 Trading Days after but not including the ex-dividend date for
such dividend or distribution, or the record date for such subdivision,
combination or reclassification, then, and in each such case, the current per
share market price shall be appropriately adjusted to reflect the current market
price per share equivalent of such Security. The closing price for each day
shall be the last sale price, regular way, reported at or prior to 4:00 P.M.
Eastern time or, in case no such sale takes place on such day, the average of
the bid and asked prices, regular way, reported as of 4:00 P.M. Eastern time, in
either case, as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the Security is not listed or admitted to trading on the
New York Stock Ex-

                                      -21-
<PAGE>

change, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Security is listed or admitted to trading or, if the Security is
not listed or admitted to trading on any national securities exchange, the last
quoted price reported at or prior to 4:00 P.M. Eastern time or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported as of 4:00 P.M. Eastern time by NASDAQ or such other system
then in use, or, if on any such date the Security is not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Security selected by the Board
of Directors of the Company. The term "Trading Day" shall mean a day on which
the principal national securities exchange on which the Security is listed or
admitted to trading is open for the transaction of business, or, if the Security
is not listed or admitted to trading on any national securities exchange, a
Business Day.

               (ii) For the purpose of any computation hereunder, the "current
per share market price" of the Preferred Shares shall be determined in
accordance with the method set forth in Section 11(d)(i). If the Preferred
Shares are not publicly traded, the "current per share market price" of the
Preferred Shares shall be conclusively deemed to be the current per share market
price of the Common Shares as determined pursuant to Section 11(d)(i) hereof
(appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof), multiplied by one hundred. If
neither the Common Shares nor the Preferred Shares are publicly held or so
listed or traded, "current per share market price" shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent.

                                      -22-
<PAGE>

               (e) No adjustment in the Purchase Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Purchase Price; provided, however, that any adjustments which by reason of this
Section 11(e) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
11 shall be made to the nearest cent or to the nearest one one-millionth of a
Preferred Share or one ten-thousandth of any other share or security as the case
may be. Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the transaction which requires such adjustment or (ii)
the date of the expiration of the right to exercise any Rights.

               (f) If, as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Company other than Preferred
Shares, thereafter the number of such other shares so receivable upon exercise
of any Right shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to the
Preferred Shares contained in Section 11(a) through (c) hereof, inclusive, and
the provisions of Sections 7, 9, 10 and 13 hereof with respect to the Preferred
Shares shall apply on like terms to any such other shares.

               (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                                      -23-
<PAGE>

               (h) Unless the Company shall have exercised its election as
provided in Section 11(i) hereof, upon each adjustment of the Purchase Price as
a result of the calculations made in Sections 11(b) and (c) hereof, each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-hundredths of a Preferred Share (calculated to the nearest one
one-millionth of a Preferred Share) obtained by (A) multiplying (x) the number
of one one-hundredths of a share covered by a Right immediately prior to this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (B) dividing the product so obtained by the
Purchase Price in effect immediately after such adjustment of the Purchase
Price.

               (i) The Company may elect, on or after the date of any adjustment
of the Purchase Price, to adjust the number of Rights in substitution for any
adjustment in the number of one one-hundredths of a Preferred Share purchasable
upon the exercise of a Right. Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the number of one
one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights, indicating the record date for the adjustment, and, if known at the
time, the amount of the adjustment to be made (with prompt written notice to the
Rights Agent of such election and, if known at the time, the amount of the
adjustment). This record date may be the date on which the Purchase Price is
adjusted or any day thereafter, but, if the Right Certificates have been issued,
shall be at

                                      -24-
<PAGE>

least 10 days later than the date of the public announcement. If Right
Certificates have been issued, upon each adjustment of the number of Rights
pursuant to this Section 11(i), the Company shall, as promptly as practicable,
cause to be distributed to holders of record of Right Certificates on such
record date Right Certificates evidencing, subject to Section 14 hereof, the
additional Rights to which such holders shall be entitled as a result of such
adjustment, or, at the option of the Company, shall cause to be distributed to
such holders of record in substitution and replacement for the Right
Certificates held by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Right Certificates evidencing
all the Rights to which such holders shall be entitled after such adjustment.
Right Certificates so to be distributed shall be issued, executed and
countersigned in the manner provided for herein, and shall be registered in the
names of the holders of record of Right Certificates on the record date
specified in the public announcement.

               (j) Irrespective of any adjustment or change in the Purchase
Price or in the number of one one-hundredths of a Preferred Share issuable upon
the exercise of the Rights, the Right Certificates theretofore and thereafter
issued may continue to express the Purchase Price and the number of one
one-hundredths of a Preferred Share which were expressed in the initial Right
Certificates issued hereunder.

               (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below one one-hundredth of the then par value, if
any, of the Preferred Shares issuable upon exercise of the Rights, the Company
shall take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price.

                                      -25-
<PAGE>

               (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer (with prompt written notice of
such election to the Rights Agent) until the occurrence of such event the
issuing to the holder of any Right exercised after such record date of the
Preferred Shares and other capital stock or securities of the Company, if any,
issuable upon such exercise over and above the Preferred Shares and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

               (m) Anything in this Section 11 to the contrary notwithstanding,
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it, in its sole discretion, shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or issuance of rights, options or
warrants referred to in Section 11(b) hereof, hereafter made by the Company to
holders of the Preferred Shares shall not be taxable to such stockholders.

               (n) In the event that, at any time after the date of this
Agreement and prior to the Distribution Date, the Company shall (i) declare or
pay any dividend on the Common Shares payable in Common Shares, or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common

                                      -26-
<PAGE>

Shares) into a greater or lesser number of Common Shares, then, in any such
case, (A) the number of one one-hundredths of a Preferred Share purchasable
after such event upon proper exercise of each Right shall be determined by
multiplying the number of one one-hundredths of a Preferred Share so purchasable
immediately prior to such event by a fraction, the numerator of which is the
number of Common Shares outstanding immediately before such event and the
denominator of which is the number of Common Shares outstanding immediately
after such event, and (B) each Common Share outstanding immediately after such
event shall have issued with respect to it that number of Rights which each
Common Share outstanding immediately prior to such event had issued with respect
to it. The adjustments provided for in this Section 11(n) shall be made
successively whenever such a dividend is declared or paid or such a subdivision,
combination or consolidation is effected.

               Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares and the Securities and Exchange Commission a copy
of such certificate and (c) if such adjustment occurs at any time after the
Distribution Date, mail a brief summary thereof to each holder of a Right
Certificate in accordance with Section 25 and Section 26 hereof. The Rights
Agent shall be fully protected in relying on any such certificate and on any
adjustment or statement therein contained and shall not have any duty or
liability with respect to and shall not be deemed to have knowledge of any
adjustment unless and until such certificate has been filed with the Rights
Agent.

               Section 13. Consolidation, Merger or Sale or Transfer of Assets
or Earning Power. In the event, directly or indirectly, at any time after a
Person has become an Acquiring Person, (a) the Company shall consolidate with,
or merge with and into, any other Person, (b) any Person shall consolidate with
the Company, or merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person (or the Company) or cash or any
other property, or (c) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person other than the Company or one or more of its wholly-owned
Subsidiaries, then, and in each such case, proper provision shall be made so
that (i) each holder of a Right (except as otherwise provided herein) shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to the then current Purchase Price multiplied by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of Common Shares of such other Person (including the Company as
successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable and
dividing that product by (B) 50% of the then current per share market price of
the Common Shares of such other Person (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; (ii) the issuer of such Common Shares shall thereafter be liable for,
and shall assume, by virtue of such consolidation, merger, sale or transfer, all
the obligations

                                      -28-
<PAGE>

and duties of the Company pursuant to this Agreement; (iii) the term "Company"
shall thereafter be deemed to refer to such issuer; and (iv) such issuer shall
take such steps (including, but not limited to, the reservation of a sufficient
number of its Common Shares in accordance with this Agreement) in connection
with such consummation as may be necessary to assure that the provisions hereof
shall thereafter be applicable, as nearly as reasonably may be, in relation to
the Common Shares of the Company thereafter deliverable upon the exercise of the
Rights. The Company shall not consummate any such consolidation, merger, sale or
transfer unless, prior thereto, the Company and such issuer shall have executed
and delivered to the Rights Agent a supplemental agreement so providing. The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights. The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

               Section 14. Fractional Rights and Fractional Shares. (a) The
Company shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right. For the purposes of this Section 14(a), the current market value of a
whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable. The closing price for any day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of
the closing bid

                                      -29-
<PAGE>

and asked prices, regular way, in either case, as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Rights are not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the Rights are
listed or admitted to trading or, if the Rights are not listed or admitted to
trading on any national securities exchange, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported by NASDAQ or such other system then in use or, if on any
such date the Rights are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Rights selected by the Board of Directors of the Company. If on
any such date no such market maker is making a market in the Rights, the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

               (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute
certificates which evidence fractional Preferred Shares (other than fractions
which are integral multiples of one one-hundredth of a Preferred Share).
Fractions of Preferred Shares in integral multiples of one one-hundredth of a
Preferred Share may, at the election of the Company, be evidenced by depositary
receipts, pursuant to an appropriate agreement between the Company and a
depositary selected by it; provided that such agreement shall provide that the
holders of such depositary receipts shall have all the rights, privileges and
preferences to which they are entitled as beneficial owners of the Preferred
Shares represented by such depositary receipts. In lieu of fractional Preferred
Shares that are not inte-

                                      -30-
<PAGE>

gral multiples of one one-hundredth of a Preferred Share, the Company shall pay
to the registered holders of Right Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the
current market value of one Preferred Share. For the purposes of this Section
14(b), the current market value of a Preferred Share shall be the closing price
of a Preferred Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

               (c) The holder of a Right, by the acceptance of the Right,
expressly waives such holder's right to receive any fractional Rights or any
fractional shares upon exercise of a Right (except as provided above).

               (d) Whenever a payment for fractional Rights or fractional shares
is to be made by the Rights Agent, the Company shall (i) promptly prepare and
deliver to the Rights Agent a certificate setting forth in reasonable detail the
facts related to such payment and the prices and/or formulas utilized in
calculating such payments, and (ii) provide sufficient monies to the Rights
Agent in the form of fully collected funds to make such payments. The Rights
Agent shall be fully protected in relying upon such a certificate and shall have
no duty with respect to any payment for fractional Rights or fractional shares
under any Section of this Agreement relating to the payment of fractional Rights
or fractional shares unless and until the Rights Agent shall have received such
a certificate and sufficient monies.

               Section 15. Rights of Action. All rights of action in respect of
this Agreement, excepting the rights of action given to the Rights Agent
hereunder, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to

                                      -31-
<PAGE>

the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), 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 to enforce, or otherwise act in respect
of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach by the Company of this
Agreement, and will be entitled to specific performance of the obligations
under, and injunctive relief against actual or threatened violations of the
obligations by the Company of any Person subject to, this Agreement.

               Section 16. Agreement of Right Holders. Every holder of a Right,
by accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

               (a) prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common Shares;

               (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the office of the Rights Agent designated for such purpose, duly endorsed or
accompanied by a proper instrument of transfer; and

               (c) the Company and the Rights Agent may deem and treat the
Person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby

                                      -32-
<PAGE>

(notwithstanding any notations of ownership or writing on the Right Certificate
or the associated Common Shares certificate made by anyone other than the
Company or the Rights Agent) for all purposes whatsoever, and neither the
Company nor the Rights Agent shall be affected by any notice to the contrary.
Notwithstanding anything in this Agreement to the contrary, neither the Company
nor the Rights Agent shall have any liability to any holder of a Right or any
other Person as a result of its inability to perform any of its obligations
under this Agreement by reason of any preliminary or permanent injunction or
other order, decree, judgment or ruling (whether interlocutory or final) issued
by a court of competent jurisdiction or by a governmental, regulatory,
self-regulatory or administrative agency or commission, or any statute, rule,
regulation or executive order promulgated or enacted by any governmental
authority, prohibiting or otherwise restraining performance of such obligation.

               Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

               Section 18. Concerning the Rights Agent. The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder, and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the preparation,
negotiation, delivery, administration, execution and amendment of this Agreement
and the exercise and performance of its duties hereunder. The Company also
agrees to indemnify the Rights Agent for, and to hold it harmless against, any
loss, liability, damage, judgment, fine, penalty, claim, demand, settlement,
cost or expense incurred without gross negligence, bad faith or willful
misconduct (as each is determined by a final, non-appealable order, judgment,
decree or ruling of a court of competent jurisdiction) on the part of the Rights
Agent, for any action taken, suffered or omitted to be taken by the Rights Agent
in connection with the execution, acceptance, amendment, exercise,
administration and performance of its duties under this Agreement, including the
costs and expenses of defending against any claim of liability in the premises
(including, without limitation, the reasonable fees and expenses of legal
counsel). The costs and expenses incurred in enforcing this right of
indemnification shall be paid by the Company. Anything to the contrary
notwithstanding, in no event shall the Rights Agent be liable for any special,
punitive, indirect, consequential or incidental loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Rights Agent
has been advised of the likelihood of such loss or damage. Any liability of the
Rights Agent under this Agreement will be limited to the amount of fees paid by
the Company to the Rights Agent. The provisions of this Section 18 and Section
20 below shall survive the exercise or expiration of the Rights, the termination
of this Agreement and the resignation or removal of the Rights Agent.

                                      -34-
<PAGE>

               The Rights Agent is authorized to rely upon, and shall be
protected and shall incur no liability for, or in respect of any action taken,
suffered or omitted by it in connection with, the acceptance and administration
of this Agreement and the exercise and performance of its duties hereunder, in
reliance upon any Right Certificate or certificate for the Preferred Shares or
Common Shares or for other securities of the Company, instrument of assignment
or transfer, power of attorney, endorsement, affidavit, letter, notice,
direction, consent, certificate, statement, or other paper or document believed
by it to be genuine and to be signed, executed and, where necessary, verified or
acknowledged, by the proper Person, or otherwise upon the advice or opinion of
counsel as set forth in Section 20 hereof. The Rights Agent shall not be deemed
to have knowledge of any event of which it was supposed to receive notice
thereof hereunder, and the Rights Agent shall be fully protected and shall incur
no liability for failing to take any action in connection therewith, unless and
until it has received such notice in writing.

               Section 19. Merger or Consolidation or Change of Name of Rights
Agent. Any Person into which the Rights Agent or any successor Rights Agent may
be merged or with which it may be consolidated, or any Person resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any Person succeeding to the shareholder services business
of the Rights Agent or any successor Rights Agent, shall be the successor to the
Rights Agent under this Agreement without the execution or filing of any paper
or any further act on the part of any of the parties hereto; provided that such
Person would be eligible for appointment as a successor Rights Agent under the
provisions of Section 21 hereof. In case at the time such successor Rights Agent
shall succeed to the agency created by this Agreement, any of the Right
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of the predecessor Rights Agent

                                      -35-
<PAGE>

and deliver such Right Certificates so countersigned; and, in case at that time
any of the Right Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Right Certificates either in the name of the
predecessor Rights Agent or in the name of the successor Rights Agent; and, in
all such cases, such Right Certificates shall have the full force provided in
the Right Certificates and in this Agreement.

               In case at any time the name of the Rights Agent shall be changed
and at such time any of the Right Certificates shall have been countersigned but
not delivered, the Rights Agent may adopt the countersignature under its prior
name and deliver Right Certificates so countersigned; and, in case at that time
any of the Right Certificates shall not have been countersigned, the Rights
Agent may countersign such Right Certificates either in its prior name or in its
changed name; and, in all such cases, such Right Certificates shall have the
full force provided in the Right Certificates and in this Agreement.

               Section 20. Duties of Rights Agent. The Rights Agent undertakes
only the duties and obligations expressly imposed by this Agreement (and no
implied duties or obligations) upon the following terms and conditions, by all
of which the Company and the holders of Right Certificates, by their acceptance
thereof, shall be bound:

               (a) The Rights Agent may consult with legal counsel (who may be
legal counsel for the Company), and, absent bad faith by the Rights Agent, the
advice or opinion of such counsel shall be full and complete authorization and
protection to the Rights Agent and the Rights Agent shall incur no liability for
or in respect of any action taken, suffered or omitted to be taken by it in
accordance with such advice or opinion.

                                      -36-
<PAGE>

               (b) Whenever in the administration, exercise and performance of
its duties under this Agreement the Rights Agent shall deem it necessary or
desirable that any fact or matter be proved or established by the Company prior
to taking, suffering or omitting to take any action hereunder, such fact or
matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
certificate signed by any one of the Chairman of the Board, the Chief Executive
Officer, the President, any Vice President, the Treasurer or the Secretary of
the Company and delivered to the Rights Agent; and, absent bad faith by the
Rights Agent, such certificate shall be full and complete authorization and
protection to the Rights Agent for, and the Rights Agent shall incur no
liability for or in respect of, any action taken, suffered or omitted to be
taken by it under the provisions of this Agreement in reliance upon such
certificate.

               (c) The Rights Agent shall be liable hereunder to the Company and
any other Person only for its own gross negligence, bad faith or willful
misconduct (as each is determined by a final, non-appealable order, judgment,
decree or ruling of a court of competent jurisdiction).

               (d) The Rights Agent is authorized to rely upon, and shall be
protected and shall incur no liability for, or in respect of any action taken,
suffered or omitted by it in connection with, any interpretation of the
provisions of this Agreement or any determinations or calculations in connection
with the administration of this Agreement (including any determination with
respect to the redemption or exchange of the Rights or to amend the Agreement)
made by the Company or its Board of Directors, and any such interpretation,
determination or calculation shall be final, conclusive and binding upon the
Rights Agent.

                                      -37-
<PAGE>

               (e) The Rights Agent shall not be liable for or by reason of any
of the statements of fact or recitals contained in this Agreement or in the
Right Certificates (except its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

               (f) The Rights Agent shall not have any liability for or be under
any responsibility in respect of the legality, validity or enforceability of
this Agreement or the execution and delivery hereof (except the due execution
hereof by the Rights Agent) or in respect of the legality, validity or
enforceability or the execution of any Right Certificate (except its
countersignature thereof); nor shall it be liable or responsible for any breach
by the Company of any covenant or condition contained in this Agreement or in
any Right Certificate; nor shall it be liable or responsible for any change in
the exercisability of the Rights (including the Rights becoming null and void
pursuant to Section 11(a)(ii) hereof) or any adjustment in the terms of the
Rights (including the manner, method or amount thereof) provided for in Section
3, 11, 13, 23 or 24 hereof, or the ascertaining of the existence of facts that
would require any such change or adjustment (except with respect to the exercise
of Rights evidenced by Right Certificates after notice has been delivered by the
Company in accordance with the terms hereof that such change or adjustment is
required); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any
Preferred Shares to be issued pursuant to this Agreement or any Right
Certificate or as to whether any Preferred Shares will, when issued, be validly
authorized and issued, fully paid and nonassessable.

               (g) The Company agrees that it will perform, execute, acknowledge
and deliver or cause to be performed, executed, acknowledged and delivered all
such further and other

                                      -38-
<PAGE>

acts, instruments and assurances as may reasonably be required by the Rights
Agent for the carrying out or performing by the Rights Agent of the provisions
of this Agreement.

               (h) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the administration, exercise and performance of its
duties hereunder from any one of the Chairman of the Board, the Chief Executive
Officer, the President, any Vice President, the Secretary or the Treasurer of
the Company, and to apply to such officers for advice or instructions in
connection with its duties, and, absent bad faith by the Rights Agent, such
instructions shall be full authorization and protection to the Rights Agent and
the Rights Agent shall incur no liability for or in respect of any action taken,
suffered or omitted to be taken by it in accordance with the instructions of any
such officer or for any delay in acting while waiting for those instructions.
The Rights Agent shall be fully authorized and protected in relying upon the
most recent instructions received by any such officer.

               (i) The Rights Agent and any stockholder, Affiliate, director,
officer or employee of the Rights Agent may buy, sell or deal in any of the
Rights or other securities of the Company or become pecuniarily interested in
any transaction in which the Company may be interested, or contract with or lend
money to the Company or otherwise act as fully and freely as though it were not
Rights Agent under this Agreement. Nothing herein shall preclude the Rights
Agent or any such stockholder, affiliate, director, officer or employee from
acting in any other capacity for the Company or for any other Person.

               (j) The Rights Agent may execute and exercise any of the rights
or powers hereby vested in it or perform any duty hereunder either itself
(through its directors, officers and employees) or by or through its attorneys
or agents, and the Rights Agent shall not be answerable

                                      -39-
<PAGE>

or accountable for any act, omission, default, neglect or misconduct of any such
attorneys or agents or for any loss to the Company or any other Person resulting
from any such act, omission, default, neglect or misconduct, absent gross
negligence, bad faith or willful misconduct (each as determined by a final,
non-appealable order, judgment, decree or ruling of a court of competent
jurisdiction) in the selection and continued employment thereof.

               (k) No provision of this Agreement shall require the Rights Agent
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder or in the exercise of its rights
if it believes that repayment of such funds or adequate indemnification against
such risk or liability is not reasonably assured to it.

               (l) If, with respect to any Right Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has not been
properly completed or executed, the Rights Agent shall not take any further
action with respect to such requested exercise or transfer without first
consulting with the Company.

               Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares known to the Rights
Agent by registered or certified mail. Following the Distribution Date, the
Company shall promptly notify the holders of the Right Certificates by
first-class mail of any such resignation. The Company may remove the Rights
Agent or any successor Rights Agent upon 30 days' notice in writing, mailed to
the Rights Agent or successor Rights Agent, as the case may be, and to each
transfer agent of the Common Shares or Preferred Shares

                                      -40-
<PAGE>

by registered or certified mail, and to the holders of the Right Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (which holder
shall, with such notice, submit such holder's Right Certificate for inspection
by the Company), then the registered holder of any Right Certificate may apply
to any court of competent jurisdiction for the appointment of a new Rights
Agent. Any successor Rights Agent, whether appointed by the Company or by such a
court, shall be a Person organized and doing business under the laws of the
United States or of any state of the United States, in good standing, which is
authorized under such laws to conduct shareholder services businesses (including
the authority under such laws to act as Rights Agent and to fulfill all
obligations and take all actions required hereunder), which has at the time of
its appointment as Rights Agent a combined capital and surplus of at least $50
million, and which is subject to supervision or examination by federal or state
authority or is a wholly owned subsidiary of a Person which is subject to such
supervision or examination. After appointment, the successor Rights Agent shall
be vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor

                                      -41-
<PAGE>

Rights Agent and each transfer agent of the Common Shares or Preferred Shares,
and mail a notice thereof in writing to the registered holders of the Right
Certificates. Failure to give any notice provided for in this Section 21,
however, or any defect therein, shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the successor
Rights Agent, as the case may be.

               Section 22. Issuance of New Right Certificates. Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by the Board of Directors of the Company to reflect
any adjustment or change in the Purchase Price and the number or kind or class
of shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Agreement.

               Section 23. Redemption. (a) The Board of Directors of the Company
may, at its option, at any time prior to such time as any Person becomes an
Acquiring Person, redeem all but not less than all the then outstanding Rights
at a redemption price of $.001 per Right, appropriately adjusted to reflect any
stock split, stock dividend or similar transaction occurring after the date
hereof (such redemption price being hereinafter referred to as the "Redemption
Price"). The redemption of the Rights by the Board of Directors of the Company
may be made effective at such time, on such basis and with such conditions as
the Board of Directors of the Company, in its sole discretion, may establish.

               (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, and without any further action and without any notice, the right to
exercise the Rights will terminate and the

                                      -42-
<PAGE>

only right thereafter of the holders of Rights shall be to receive the
Redemption Price. The Company shall promptly give public notice of any such
redemption (with prompt written notice thereof to the Rights Agent); provided,
however, that the failure to give, or any defect in, any such notice shall not
affect the legality or validity of such redemption. Within 10 days after such
action of the Board of Directors of the Company ordering the redemption of the
Rights, the Company shall mail a notice of redemption to all the holders of the
then outstanding Rights at their last addresses as they appear upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent for the Common Shares. Any notice which is mailed in
the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of redemption will state the method by
which the payment of the Redemption Price will be made. Neither the Company nor
any of its Affiliates or Associates may redeem, acquire or purchase for value
any Rights at any time in any manner other than that specifically set forth in
this Section 23 or in Section 24 hereof, and other than in connection with the
purchase of Common Shares prior to the Distribution Date.

               Section 24. Exchange. (a) The Board of Directors of the Company
may, at its option, at any time after any Person becomes an Acquiring Person,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become null and void pursuant to the provisions of
Section 11(a)(ii) hereof) for Common Shares at an exchange ratio of one Common
Share per Right, appropriately adjusted to reflect any adjustment in the number
of Rights pursuant to Section 11(i) (such exchange ratio being hereinafter
referred to as the "Exchange Ratio"). Notwithstanding the foregoing, the Board
of Directors of the Company shall not be empowered to effect such exchange at
any time after any Person (other than the Company, any Subsidiary of the
Company, any employee benefit plan of the Company or any

                                      -43-
<PAGE>

such Subsidiary, or any entity holding Common Shares for or pursuant to the
terms of any such plan), together with all Affiliates and Associates of such
Person, becomes the Beneficial Owner of 50% or more of the Common Shares then
outstanding.

               (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice of any such exchange (with prompt
written notice thereof to the Rights Agent); provided, however, that the failure
to give, or any defect in, such notice shall not affect the legality or validity
of such exchange. The Company promptly shall mail a notice of any such exchange
to all of the holders of such Rights at their last addresses as they appear upon
the registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Common Shares for Rights will be effected, and, in the event of any
partial exchange, the number of Rights which will be exchanged. Any partial
exchange shall be effected pro rata based on the number of Rights (other than
Rights which have become null and void pursuant to the provisions of Section
11(a)(ii) hereof) held by each holder of Rights.

               (c) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit any exchange of
Rights as contemplated in accordance with this Section 24, the Company shall
take all such action as may be necessary to authorize additional Common Shares
for issuance upon exchange of the Rights. In the event the

                                      -44-
<PAGE>

Company shall, after good faith effort, be unable to take all such action as may
be necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exchange
of a Right, a number of Preferred Shares or fraction thereof such that the
current per share market price of one Preferred Share multiplied by such number
or fraction is equal to the current per share market price of one Common Share
as of the date of issuance of such Preferred Shares or fraction thereof.

               (d) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares. In lieu of such fractional Common Shares, the Company shall pay to the
registered holders of the Right Certificates with regard to which such
fractional Common Shares would otherwise be issuable an amount in cash equal to
the same fraction of the current market value of a whole Common Share. For the
purposes of this paragraph (d), the current market value of a whole Common Share
shall be the closing price of a Common Share (as determined pursuant to the
second sentence of Section 11(d)(i) hereof) for the Trading Day immediately
prior to the date of exchange pursuant to this Section 24.

               Section 25. Notice of Certain Events. (a) In case the Company
shall, at any time after the Distribution Date, propose (i) to pay any dividend
payable in stock of any class to the holders of the Preferred Shares or to make
any other distribution to the holders of the Preferred Shares (other than a
regular quarterly cash dividend), (ii) to offer to the holders of the Preferred
Shares rights or warrants to subscribe for or to purchase any additional
Preferred Shares or shares of stock of any class or any other securities, rights
or options, (iii) to effect any reclassification of the Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect

                                      -45-
<PAGE>

any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to the Rights Agent and to each holder of a Right Certificate, in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, or distribution
of rights or warrants, or the date on which such reclassification,
consolidation, merger, sale, transfer, liquidation, dissolution, or winding up
is to take place and the date of participation therein by the holders of the
Common Shares and/or Preferred Shares, if any such date is to be fixed, and such
notice shall be so given in the case of any action covered by clause (i) or (ii)
above at least 10 days prior to the record date for determining holders of the
Preferred Shares for purposes of such action, and, in the case of any such other
action, at least 10 days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the Common Shares and/or
Preferred Shares, whichever shall be the earlier.

               (b) In case the event set forth in Section 11(a)(ii) hereof shall
occur, then the Company shall, as soon as practicable thereafter, give to the
Rights Agent and each holder of a Right Certificate, in accordance with Section
26 hereof, a notice of the occurrence of such event, which notice shall describe
such event and the consequences of such event to holders of Rights under Section
11(a)(ii) hereof.

               Section 27. Supplements and Amendments. The Company may from time
to time supplement or amend this Agreement without the approval of any holders
of Right Certificates in order to cure any ambiguity, to correct or supplement
any provision contained herein which may be defective or inconsistent with any
other provisions herein, or to make any other provisions with respect to the
Rights which the Company may deem necessary or desirable, any such supplement or
amendment to be evidenced by a writing signed by the Company and the Rights
Agent; provided, however, that, from and after such time as any Person becomes
an Acquiring Person, this Agreement shall not be amended in any manner which
would adversely affect the interests of the holders of Rights. Without limiting
the foregoing, the Company may at any time prior to such time as any Person
becomes an Acquiring Person amend this Agreement to lower the thresholds set
forth in Section 1(a) and 3(a) hereof to not less than 10% (the "Reduced
Threshold"); provided, however, that no Person who beneficially owns a number of
Common Shares equal to or greater than the Reduced Threshold shall become an
Acquiring Person unless such Person shall, after the public announcement of the
Reduced Threshold, increase its beneficial ownership of the then outstanding
Common Shares (other than as a result of an acquisition of Common Shares by the
Company) to an amount equal to or greater than the greater of (x) the Reduced
Threshold or (y) the sum of (i) the lowest beneficial ownership of such Person
as a percentage of the outstanding Common Shares as of any date on or after the
date of the public announcement of such Reduced Threshold plus (ii) .001%.

               Upon delivery of a certificate from an appropriate officer of the
Company which states that the proposed supplement or amendment is in compliance
with the terms of this Section 27, the Rights Agent shall execute such
supplement or amendment unless the Rights Agent shall have determined in good
faith that such supplement or amendment would increase the Rights

                                      -48-
<PAGE>

Agent's duties, liabilities or obligations, or would reduce the Rights Agent's
rights or immunities, under this Agreement; provided, that any amendment to the
definition of Acquiring Person in Section 1(a) hereof shall not be deemed to
increase the Rights Agent's duties, liabilities or obligations, or reduce the
Rights Agent's rights or immunities, under this Agreement.

               Section 28. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

               Section 29. Benefits of this Agreement. Nothing in this Agreement
shall be construed to give to any Person other than the Company, the Rights
Agent and the registered holders of the Right Certificates (and, prior to the
Distribution Date, the Common Shares) any legal or equitable right, remedy or
claim under this Agreement; but this Agreement shall be for the sole and
exclusive benefit of the Company, the Rights Agent and the registered holders of
the Right Certificates (and, prior to the Distribution Date, the Common Shares).

               Section 30. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

               Section 31. Governing Law. This Agreement and each Right
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for

                                      -49-
<PAGE>

all purposes shall be governed by and construed in accordance with the laws of
such state applicable to contracts to be made and performed entirely within such
state; provided, however, that all provisions regarding the rights, duties and
obligations of the Rights Agent shall be governed by and construed in accordance
with the laws of the State of New York applicable to contracts made and to be
performed entirely within such State.

               Section 32. Counterparts. This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

                             OVERTURE SERVICES, INC.

                         (Pursuant to Section 151 of the
                        Delaware General Corporation Law)

                             ----------------------

               Overture Services, Inc., a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Company"), hereby certifies that the following resolution was adopted
by the Board of Directors of the Company as required by Section 151 of the
General Corporation Law at a meeting duly called and held on March 8, 2002:

               RESOLVED, that pursuant to the authority granted to and vested in
the Board of Directors of this Company (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, the Board of Directors hereby creates a series of Preferred
Stock, par value $0.0001 per share, of the Company (the "Preferred Stock"),
and hereby states the designation and number of shares, and fixes the relative
rights, preferences, and limitations thereof as follows:

               Series A Junior Participating Preferred Stock:

               Section 1. Designation and Amount. The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" (the
"Series A Preferred Stock") and the number of shares constituting the Series A
Preferred Stock shall be 2,000,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Company
convertible into Series A Preferred Stock.

               Section 2. Dividends and Distributions.

               (A) Subject to the rights of the holders of any shares of any
        series of Preferred Stock (or any similar stock) ranking prior and
        superior to the Series A Preferred Stock

                                      A-1

<PAGE>

        with respect to dividends, the holders of shares of Series A Preferred
        Stock, in preference to the holders of Common Stock, par value $0.0001
        per share (the "Common Stock"), of the Company, and of any other
        junior stock, shall be entitled to receive, when, as and if declared by
        the Board of Directors out of funds legally available for the purpose,
        quarterly dividends payable in cash on the first day of March, June,
        September and December in each year (each such date being referred to
        herein as a "Quarterly Dividend Payment Date"), commencing on the first
        Quarterly Dividend Payment Date after the first issuance of a share or
        fraction of a share of Series A Preferred Stock, in an amount per share
        (rounded to the nearest cent) equal to the greater of (a) $1 or (b)
        subject to the provision for adjustment hereinafter set forth, 100 times
        the aggregate per share amount of all cash dividends, and 100 times the
        aggregate per share amount (payable in kind) of all non-cash dividends
        or other distributions, other than a dividend payable in shares of
        Common Stock or a subdivision of the outstanding shares of Common Stock
        (by reclassification or otherwise), declared on the Common Stock since
        the immediately preceding Quarterly Dividend Payment Date or, with
        respect to the first Quarterly Dividend Payment Date, since the first
        issuance of any share or fraction of a share of Series A Preferred
        Stock. In the event the Company shall at any time declare or pay any
        dividend on the Common Stock payable in shares of Common Stock, or
        effect a subdivision or combination or consolidation of the outstanding
        shares of Common Stock (by reclassification or otherwise than by payment
        of a dividend in shares of Common Stock) into a greater or lesser number
        of shares of Common Stock, then in each such case the amount to which
        holders of shares of Series A Preferred Stock were entitled immediately
        prior to such event under clause (b) of the preceding sentence shall be
        adjusted by multiplying such amount by a fraction, the numerator of
        which is the number of shares of Common Stock outstanding immediately
        after such event and the denominator of which is the number of shares of
        Common Stock that were outstanding immediately prior to such event.

               (B) The Company shall declare a dividend or distribution on
        the Series A Preferred Stock as provided in paragraph (A) of this
        Section immediately after it declares a dividend or distribution on the
        Common Stock (other than a dividend payable in shares of Common Stock);
        provided that, in the event no dividend or distribution shall have been
        declared on the Common Stock during the period between any Quarterly
        Dividend Payment Date and the next subsequent Quarterly Dividend Payment
        Date, a dividend of $1 per share on the Series A Preferred Stock shall
        nevertheless be payable on such subsequent Quarterly Dividend Payment
        Date.

               (C) Dividends shall begin to accrue and be cumulative on
        outstanding shares of Series A Preferred Stock from the Quarterly
        Dividend Payment Date next preceding the date of issue of such shares,
        unless the date of issue of such shares is prior to the record date for
        the first Quarterly Dividend Payment Date, in which case dividends on
        such shares shall begin to accrue from the date of issue of such shares,
        or unless the date of issue is a Quarterly Dividend Payment Date or is a
        date after the record date for the determination of holders of shares of
        Series A Preferred Stock entitled to receive a quarterly dividend and
        before such Quarterly Dividend Payment Date, in either of which events
        such dividends shall begin to accrue and be cumulative from such
        Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not
        bear interest. Dividends paid on

                                      A-2

<PAGE>

        the shares of Series A Preferred Stock in an amount less than the total
        amount of such dividends at the time accrued and payable on such shares
        shall be allocated pro rata on a share-by-share basis among all such
        shares at the time outstanding. The Board of Directors may fix a record
        date for the determination of holders of shares of Series A Preferred
        Stock entitled to receive payment of a dividend or distribution declared
        thereon, which record date shall be not more than 60 days prior to the
        date fixed for the payment thereof.

               Section 3. Voting Rights. The holders of shares of Series A
Preferred Stock shall have the following voting rights:

               (A) Subject to the provision for adjustment hereinafter set
        forth, each share of Series A Preferred Stock shall entitle the holder
        thereof to 100 votes on all matters submitted to a vote of the
        stockholders of the Company. In the event the Company shall at
        any time declare or pay any dividend on the Common Stock payable in
        shares of Common Stock, or effect a subdivision or combination or
        consolidation of the outstanding shares of Common Stock (by
        reclassification or otherwise than by payment of a dividend in shares of
        Common Stock) into a greater or lesser number of shares of Common Stock,
        then in each such case the number of votes per share to which holders of
        shares of Series A Preferred Stock were entitled immediately prior to
        such event shall be adjusted by multiplying such number by a fraction,
        the numerator of which is the number of shares of Common Stock
        outstanding immediately after such event and the denominator of which is
        the number of shares of Common Stock that were outstanding immediately
        prior to such event.

               (B) Except as otherwise provided herein, in any other Certificate
        of Designations creating a series of Preferred Stock or any similar
        stock, or by law, the holders of shares of Series A Preferred Stock and
        the holders of shares of Common Stock and any other capital stock of the
        Company having general voting rights shall vote together as one
        class on all matters submitted to a vote of stockholders of the
        Company.

               (C) Except as set forth herein, or as otherwise provided by law,
        holders of Series A Preferred Stock shall have no special voting rights
        and their consent shall not be required (except to the extent they are
        entitled to vote with holders of Common Stock as set forth herein) for
        taking any corporate action.

               Section 4. Certain Restrictions.

               (A) Whenever quarterly dividends or other dividends or
        distributions payable on the Series A Preferred Stock as provided in
        Section 2 are in arrears, thereafter and until all accrued and unpaid
        dividends and distributions, whether or not declared, on shares of
        Series A Preferred Stock outstanding shall have been paid in full, the
        Company shall not:

                        (i) declare or pay dividends, or make any other
                distributions, on any shares of stock ranking junior (either as
                to dividends or upon liquidation, dissolution or winding up) to
                the Series A Preferred Stock;

                                      A-3

<PAGE>

                        (ii) declare or pay dividends, or make any other
                distributions, on any shares of stock ranking on a parity
                (either as to dividends or upon liquidation, dissolution or
                winding up) with the Series A Preferred Stock, except dividends
                paid ratably on the Series A Preferred Stock and all such parity
                stock on which dividends are payable or in arrears in proportion
                to the total amounts to which the holders of all such shares are
                then entitled;

                        (iii) redeem or purchase or otherwise acquire for
                consideration shares of any stock ranking junior (either as to
                dividends or upon liquidation, dissolution or winding up) to the
                Series A Preferred Stock, provided that the Company may at
                any time redeem, purchase or otherwise acquire shares of any
                such junior stock in exchange for shares of any stock of the
                Company ranking junior (either as to dividends or upon
                dissolution, liquidation or winding up) to the Series A
                Preferred Stock; or

                        (iv) redeem or purchase or otherwise acquire for
                consideration any shares of Series A Preferred Stock, or any
                shares of stock ranking on a parity with the Series A Preferred
                Stock, except in accordance with a purchase offer made in
                writing or by publication (as determined by the Board of
                Directors) to all holders of such shares upon such terms as the
                Board of Directors, after consideration of the respective annual
                dividend rates and other relative rights and preferences of the
                respective series and classes, shall determine in good faith
                will result in fair and equitable treatment among the respective
                series or classes.

               (B) The Company shall not permit any subsidiary of the
        Company to purchase or otherwise acquire for consideration any
        shares of stock of the Company unless the Company could, under
        paragraph (A) of this Section 4, purchase or otherwise acquire such
        shares at such time and in such manner.

               Section 5. Reacquired Shares. Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Company in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof. All such shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of a new series
of Preferred Stock subject to the conditions and restrictions on issuance set
forth herein, in the Certificate of Incorporation, or in any other Certificate
of Designations creating a series of Preferred Stock or any similar stock or as
otherwise required by law.

               Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquida-

                                      A-4

<PAGE>

tion, dissolution or winding up) with the Series A Preferred Stock, except
distributions made ratably on the Series A Preferred Stock and all such parity
stock in proportion to the total amounts to which the holders of all such shares
are entitled upon such liquidation, dissolution or winding up. In the event the
Company shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under the proviso in clause (1) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

               Section 7. Consolidation, Merger, etc. In case the Company
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case each share
of Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Company shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

               Section 8. No Redemption. The shares of Series A Preferred Stock
shall not be redeemable.

               Section 9. Rank. The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets, junior to
all series of any other class of the Company's Preferred Stock.

               Section 10. Amendment. The Certificate of Incorporation of the
Company shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

Introduction

               On March 8, 2002, the board of directors of our Company, Overture
Services, Inc., a Delaware corporation, declared a dividend of one preferred
share purchase right (a "Right") for each outstanding share of common stock, par
value $0.0001 per share. The dividend is payable on March 29, 2002 to the
stockholders of record as of the close of business on March 29, 2002.

               Our board of directors has adopted this share purchase rights
plan to protect stockholders from coercive or otherwise unfair takeover tactics.
In general terms, it works by imposing a significant penalty upon any person or
group which acquires 15% or more of our outstanding common stock without the
approval of our board. The share purchase rights plan should not interfere with
any merger or other business combination approved by our board.

               For those interested in the specific terms of the share purchase
rights plan as made between our Company and Mellon Investor Services LLC, a New
Jersey limited liability company, as rights agent, as of March 15, 2002, we
provide the following summary description. Please note, however, that this
description is only a summary, and is not complete, and should be read together
with the entire share purchase rights plan, which has been filed with the
Securities and Exchange Commission as an exhibit to a Registration Statement on
Form 8-A dated March 25, 2002. A copy of the agreement is available free of
charge from our Company.

The Rights. Our board of directors authorized the issuance of a Right with
respect to each outstanding share of common stock on March 8, 2002. The Rights
will initially trade with, and will be inseparable from, the common stock. The
Rights are evidenced only by certificates that represent shares of common stock.
New Rights will accompany any new shares of common stock we issue after March
29, 2002 until the distribution date described below.

Exercise Price. Each Right will allow its holder to purchase from our Company
one one-hundredth of a share of Series A Junior Participating Preferred Stock
("preferred share") for $200, once the Rights become exercisable. This portion
of a preferred share will give the stockholder approximately the same dividend,
voting, and liquidation rights as would one share of common stock. Prior to
exercise, the Right does not give its holder any dividend, voting, or
liquidation rights.

Exercisability. The Rights will not be exercisable until

-   10 days after the public announcement that a person or group has become an
    "Acquiring Person" by obtaining beneficial ownership of 15% or more of our
    outstanding common stock, or, if earlier,

-   10 business days (or a later date determined by our board of directors
    before any person or group becomes an Acquiring Person) after a person or
    group begins a tender or exchange offer which, if completed, would result in
    that person or group becoming an Acquiring Person.

                                      C-1

               We refer to the date when the Rights become exercisable as the
"Distribution Date." Until that date, the common stock certificates will also
evidence the Rights, and any transfer of shares of common stock will constitute
a transfer of Rights. After the Distribution Date, the Rights will separate from
the common stock and be evidenced by book-entry credits or by Rights
certificates that we will mail to all eligible holders of common stock. Any
Rights held by an Acquiring Person are null and void and may not be exercised.

               Our board of directors may reduce the threshold at which a person
or group becomes an Acquiring Person from 15% to not less than 10% of the
outstanding common stock.

Consequences of a Person or Group Becoming an Acquiring Person.

-   Flip In. If a person or group becomes an Acquiring Person, all holders of
    Rights except the Acquiring Person may, for $200, purchase shares of our
    common stock with a market value of $400, based on the market price of the
    common stock prior to such acquisition.

-   Flip Over. If our Company is later acquired in a merger or similar
    transaction after the Distribution Date, all holders of Rights except the
    Acquiring Person may, for $200, purchase shares of the acquiring corporation
    with a market value of $400 based on the market price of the acquiring
    corporation's stock, prior to such merger.

Preferred Share Provisions.

Each one one-hundredth of a preferred share, if issued:

-   will not be redeemable.

-   will entitle holders to quarterly dividend payments of $.01 per share, or an
    amount equal to the dividend paid on one share of common stock, whichever is
    greater.

-   will entitle holders upon liquidation either to receive $1 per share or an
    amount equal to the payment made on one share of common stock, whichever is
    greater.

-   will have the same voting power as one share of common stock.

-   if shares of our common stock are exchanged via merger, consolidation, or a
    similar transaction, will entitle holders to a per share payment equal to
    the payment made on one share of common stock.

The value of one one-hundredth interest in a preferred share should approximate
the value of one share of common stock.

Expiration. The Rights will expire on March 29, 2012.

Redemption. Our board of directors may redeem the Rights for $.001 per Right at
any time before any person or group becomes an Acquiring Person. If our board
redeems any Rights, it must redeem all of the Rights. Once the Rights are
redeemed, the only right of the holders of

                                      C-2

<PAGE>

Rights will be to receive the redemption price of $.001 per Right. The
redemption price will be adjusted if we have a stock split or pay stock
dividends on our common stock.

Exchange. After a person or group becomes an Acquiring Person, but before an
Acquiring Person owns 50% or more of our outstanding common stock, our board of
directors may extinguish the Rights by exchanging one share of common stock or
an equivalent security for each Right, other than Rights held by the Acquiring
Person.

Anti-Dilution Provisions. Our board of directors may adjust the purchase price
of the preferred shares, the number of preferred shares issuable and the number
of outstanding Rights to prevent dilution that may occur from a stock dividend,
a stock split or a reclassification of the preferred shares or common stock. No
adjustments to the exercise price of less than 1% will be made.

Amendments. The terms of the share purchase rights plan may be amended by our
board of directors without the consent of the holders of the Rights. However,
our board may not amend the share purchase rights plan to lower the threshold at
which a person or group becomes an Acquiring Person to below 10% of our
outstanding common stock. In addition, the board may not cause a person or group
to become an Acquiring Person by lowering this threshold below the percentage
interest that such person or group already owns. After a person or group becomes
an Acquiring Person, our board may not amend the agreement in a way that
adversely affects holders of the Rights.
