                                RIGHTS AGREEMENT

               Rights Agreement, dated as of ____________, 2002, between
Advanced Medical Optics, Inc., a Delaware corporation (the "Company"), and
______________, as Rights Agent (the "Rights Agent").

                                    RECITALS

               WHEREAS, on _________, 2002, the Board of Directors of the
Company adopted this Agreement, and has authorized and declared a dividend of
one preferred share purchase right (a "Right") for each Common Share (as defined
in Section 1.6) of the Company outstanding at the close of business on
__________, 2002 (the "Record Date") and has authorized and directed the
issuance of one Right (subject to adjustment as provided herein) with respect to
each Common Share that shall become outstanding between the Record Date and the
earliest of the Distribution Date and the Expiration Date (as such terms are
defined in Sections 3.1 and 7.1), each Right initially representing the right to
purchase one one-hundredth (subject to adjustment) of a share of Series A Junior
Participating Preferred Stock (the "Preferred Shares") of the Company having the
rights, powers and preferences set forth in the form of Certificate of
Designation attached hereto as Exhibit A, upon the terms and subject to the
conditions hereinafter set forth PROVIDED, HOWEVER, that Rights may be issued
with respect to Common Shares that shall become outstanding after the
Distribution Date and prior to the Expiration Date in accordance with Section
22.

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

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

               1.1 "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates and Associates
(as such terms are hereinafter defined) of such Person, shall be the Beneficial
Owner (as such term is hereinafter defined) of ____% or more of the Common
Shares of the Company then outstanding but shall not include an Exempt Person
(as such term is hereinafter defined). 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 shares outstanding,
increases the proportionate number of shares beneficially owned by such Person
to ____% or more of the Common Shares of the Company then outstanding; PROVIDED,
HOWEVER, that if a Person shall become the Beneficial Owner of ____% or more of
the Common Shares of the Company then outstanding solely by reason of share
purchases by the Company and shall, after such share purchases by the Company,
become the Beneficial Owner of one or more additional Common Shares of the
Company (other than pursuant to a dividend or distribution paid or made by the
Company on the outstanding Common Shares in Common Shares or pursuant to a split
or subdivision of the outstanding Common Shares), then such Person shall be
deemed to be an "Acquiring Person" unless upon becoming the Beneficial Owner of
such additional shares of Common Stock such Person does not beneficially own
____% or more of the shares of Common Stock then outstanding. Notwithstanding
the foregoing, if the Board of Directors of the Company



                                       1
<PAGE>
determines in good faith that a Person who would otherwise be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this Section 1.1,
has become such inadvertently (including, without limitation, because (A) such
Person was unaware that it beneficially owned a percentage of Common Stock that
would otherwise cause such Person to be an "Acquiring Person" or (B) such Person
was aware of the extent of its Beneficial Ownership of Common Stock but had no
actual knowledge of the consequences of such Beneficial Ownership under this
Agreement), and without any intention of changing or influencing control of the
Company, 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 Section 1.1, then such
Person shall not be deemed to be or have become an "Acquiring Person" at any
time for any purposes of this Agreement. For all purposes of this Agreement, any
calculation of the number of Common Shares outstanding at any particular time,
including for purposes of determining the particular percentage of such
outstanding Common Shares of which any Person is the Beneficial Owner, shall be
made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General
Rules and Regulations under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), as in effect on the date of this Agreement.

               1.2 "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations, under the Exchange Act, as in effect on the date of this Agreement.

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

                      (i) which such Person or any of such Person's Affiliates
or Associates beneficially owns, directly or indirectly (as determined pursuant
to Rule 13d-3 of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement);

                      (ii) which such Person or any of such Person's Affiliates
or Associates, directly or indirectly, has (A) the right to acquire (whether
such right is exercisable immediately, or only after the passage of time,
compliance with regulatory requirements, fulfillment of a condition or
otherwise) pursuant to any agreement, arrangement or understanding, whether or
not in writing (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,
warrants or options, or otherwise; PROVIDED, HOWEVER, that a Person shall not be
deemed the Beneficial Owner of, or to beneficially own, (w) 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, (x) securities which such Person has a right
to acquire upon the exercise of Rights at any time prior to the time that any
Person becomes an Acquiring Person, (y) securities issuable upon the exercise of
Rights from and after the time that any Person becomes an Acquiring Person if
such Rights were acquired by such Person or any of such Person's Affiliates or
Associates prior to the Distribution Date or pursuant to Section 3.1 or Section
22 ("Original Rights") or pursuant to Section 11.9 or Section 11.15 with respect
to an adjustment to Original Rights or (z) securities which such Person or any
of such Person's Affiliates or Associates may acquire, does or do acquire or may
be deemed to acquire or may be



                                       2
<PAGE>
deemed to have the right to acquire, pursuant to any merger or other acquisition
agreement between the Company and such Person (or one or more of such Person's
Affiliates or Associates) if prior to such Person becoming an Acquiring Person
the Board of Directors of the Company has approved such agreement and determined
that such Person shall not be or be deemed to be the beneficial owner of such
securities within the meaning of this Section 1.3; or (B) the right to vote
pursuant to any agreement, arrangement or understanding (whether or not in
writing); PROVIDED, HOWEVER, that a Person shall not be deemed the Beneficial
Owner of, or to beneficially own, any security under this clause (B) 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 of 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 (or any Affiliate or Associate thereof) and with
respect to 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 securities), whether or not in writing, for the purpose
of acquiring, holding, voting (except pursuant to a revocable proxy or consent
as described in the proviso to Section 1.3(ii)(B)) or disposing of any
securities of the Company; PROVIDED, HOWEVER, that no Person who is an officer,
director or employee of an Exempt Person shall be deemed, solely by reason of
such Person's status or authority as such, to be the "Beneficial Owner" of, to
have "Beneficial Ownership" of or to "beneficially own" any securities that are
"beneficially owned" (as defined in this Section 1.3), including, without
limitation, in a fiduciary capacity, by an Exempt Person or by any other such
officer, director or employee of an Exempt Person.

               1.4 "Business Day" shall mean any day other than a Saturday,
Sunday, or a day on which banking institutions in the State of New York are
authorized or obligated by law or executive order to close.

               1.5 "close of business" on any given date shall mean 5:00 p.m.,
New York time, on such date; PROVIDED, HOWEVER, that if such date is not a
Business Day it shall mean 5:00 p.m., New York time, on the next succeeding
Business Day.

               1.6 "Common Shares" when used with reference to the Company shall
mean the shares of common stock, par value $.01 per share, of the Company.
"Common Shares" when used with reference to any Person other than the Company
shall mean the capital stock with the greatest voting power, or the equity
securities or other equity interest having power to control or direct the
management, of such other Person or, if such Person is a Subsidiary (as such
term is hereinafter defined) of another Person, the Person or Persons which
ultimately control such first-mentioned Person, and which has issued and
outstanding such capital stock, equity securities or equity interest.

               1.7 "Exempt Person" shall mean (a) Allergan, Inc. ("Allergan"),
which, as of the date hereof, beneficially owns all of the Common Stock of the
Company outstanding as of the date hereof; provided, however, that Allergan
shall cease to be an Exempt Person for all purposes hereunder on the first
Business Day after the date on which Allergan distributes to its



                                       3
<PAGE>
stockholders all of the shares of the Company's Common Stock (together with the
Rights associated therewith) then held be Allergan; and (b) the Company, any
Subsidiary of the Company, in each case including, without limitation, its
fiduciary capacity, or any employee benefit plan of the Company or of any
Subsidiary of the Company or any entity or trustee holding shares of capital
stock of the Company for or pursuant to the terms of any such plan, or for the
purpose of funding other employee benefits for employees of the Company or any
Subsidiary of the Company.

               1.8 "Person" shall mean any individual, partnership, joint
venture, limited liability company, firm, corporation, unincorporated
association, trust or other entity, and shall include any successor (by merger
or otherwise) of such entity.

               1.9 "Shares Acquisition Date" shall mean the first date of public
announcement (which, for purposes of this definition, shall include, without
limitation, the filing of a report pursuant to Section 13(d) of the Exchange Act
or pursuant to a comparable successor statute) by the Company or an Acquiring
Person that an Acquiring Person has become such or that discloses information
which reveals the existence of an Acquiring Person or such earlier date as a

               1.10 "Subsidiary" of any Person shall mean any corporation or
other entity of which a majority of the voting power of the voting equity

Company may from time to time appoint such co-Rights Agents as it may deem
necessary or desirable. In the event the Company appoints one or more co-Rights

               Section 3. Issuance of Right Certificates.

               3.1 Rights Evidenced by Share Certificates. Until the earlier of
(i) the tenth day after the Shares Acquisition Date or (ii) the tenth Business
Day after the date of the commencement of, or first public announcement of the
intent of any Person (other than an Exempt Person) to commence, a tender or
exchange offer the consummation of which would result in any Person (other than
an Exempt Person) becoming the Beneficial Owner of Common Shares aggregating
____% or more of the then outstanding Common Shares of the Company (the earlier
of (i) and (ii) being herein referred to as the "Distribution Date"), (x) the
Rights (unless earlier expired, redeemed or terminated) will be evidenced
(subject to the provisions of Section 3.2) by the certificates for Common Shares
registered in the names of the holders thereof (which certificates for Common
Shares shall also be deemed to be Right Certificates) and not by separate
certificates, and (y) the Rights (and the right to receive certificates
therefor) will be transferable only in connection with the transfer of the
underlying Common Shares. The preceding sentence notwithstanding, prior to the
occurrence of a Distribution Date specified as a result of an event described in
clause (ii) (or such later Distribution Date as the Board of Directors of the
Company may select pursuant to this sentence), the Board of Directors may
postpone, one or more times, the Distribution Date which would occur as a result
of an event described in clause (ii) beyond the date set forth in such clause
(ii). Nothing herein shall permit such a postponement of a Distribution Date
after a Person becomes an Acquiring Person. As soon as practicable after the
Distribution Date, the Company will prepare and execute, the Rights Agent will
countersign and the Company (or, if requested, the Rights Agent) will send, by
first-class, postage-prepaid mail, to each record holder of Common Shares as of
the close of business on the Distribution Date (other than any Acquiring Person
or any Associate or Affiliate of an Acquiring Person), at the address of such
holder shown on the records of the Company, one or more certificates for Rights,
in substantially the form of Exhibit B hereto (a "Right Certificate"),
evidencing one Right (subject to adjustment as provided herein) for each Common
Share so held. As of the Distribution Date, the Rights will be evidenced solely
by such Right Certificates.

               3.2 Summary of Rights. On the Record Date or as soon as
practicable thereafter, the Company will send or cause to be sent a copy of a
Summary of Rights to Purchase Preferred Shares, in substantially the form
attached hereto as Exhibit C (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 outstanding as of
the close of business on the Record Date, until the Distribution Date (or the
earlier Expiration Date), the Rights will be evidenced by such certificates for
Common Shares registered in the names of the holders thereof together with a
copy of the Summary of Rights and the registered holders of the Common Shares
shall also be registered holders of the associated Rights. Until the
Distribution Date (or the earlier Expiration Date), the surrender for transfer
of any certificate for Common Shares outstanding at the close of business on the
Record Date, with or without a copy of the Summary of Rights, shall also
constitute the transfer of the Rights associated with the Common Shares
represented thereby.

               3.3 New Certificates After Record Date. Certificates for Common
Shares which become outstanding (whether upon issuance out of authorized but
unissued Common



                                       6
<PAGE>
Shares, disposition out of treasury or transfer or exchange of outstanding
Common Shares) after the Record Date but prior to the earliest of the
Distribution Date or the Expiration Date, shall have impressed, printed,
stamped, written or otherwise affixed onto them the following legend:

        This certificate also evidences and entitles the holder hereof to
        certain rights as set forth in an Agreement between Advanced Medical
        Optics, Inc. (the "Company") and ______________, as Rights Agent, dated
        as of _____________, 2002, as the same 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 the Company. Under certain circumstances, as set forth in the
        Agreement, such Rights will be evidenced by separate certificates and
        will no longer be evidenced by this certificate. The Company will mail
        to the holder of this certificate a copy of the Agreement without charge
        after receipt of a written request therefor. AS DESCRIBED IN THE
        AGREEMENT, RIGHTS WHICH ARE OWNED BY, TRANSFERRED TO OR HAVE BEEN OWNED
        BY ACQUIRING PERSONS OR ASSOCIATES OR AFFILIATES THEREOF (AS DEFINED IN
        THE AGREEMENT) SHALL BECOME NULL AND VOID AND WILL NO LONGER BE
        TRANSFERABLE.

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

               Notwithstanding this Section 3.3, the omission of a legend shall
not affect the enforceability of any part of this Agreement or the rights of any
holder of the Rights.

               Section 4. Form of Right Certificates. The Right Certificates
(and the forms of election to purchase shares, certification and 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 as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange or trading system on which the Rights may from time to time be listed
or quoted, or to conform to usage. Subject to the terms and conditions hereof,
the Right Certificates, whenever issued, shall be dated as of the Record Date,
and shall show the date of countersignature by the Rights Agent, and on their
face 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.


                                       7
<PAGE>
               Section 5. Countersignature and Registration. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board of Directors, the Chief Executive Officer, President or any Vice
President, either manually or by facsimile signature, and shall have affixed
thereto the Company's seal or a facsimile thereof which shall be attested by the
Secretary or any Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be countersigned, either
manually or by facsimile signature, by an authorized signatory of the Rights
Agent, but it shall not be necessary for the same signatory to countersign all
of the Right Certificates hereunder. No Right Certificate shall be valid for any
purpose unless so 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 person 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 person 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, although at the date of the execution of this Agreement any
such person was not such an officer.

               Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its principal office, 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, the certificate
number of 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 11.1.2 and Section 14, at any time after the close
of business on the Distribution Date, and at or prior to the close of business
on the Expiration Date, any Right Certificate or Right Certificates (other than
Right Certificates representing Rights that have become void pursuant to Section
11.1.2 or that have been exchanged pursuant to Section 27) may be transferred,
split up or 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 or combine or exchange any Right
Certificate shall make such request in writing delivered to the Rights Agent,
and shall surrender, together with any required form of assignment and
certificate duly completed, the Right Certificate or Right Certificates to be
transferred, split up or 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 Certificates until the registered holder
shall have 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 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


                                       8
<PAGE>
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up or combination or exchange of such Right Certificates.

               Subject to the provisions of Section 11.1.2 , at any time after
the Distribution Date and prior to the Expiration Date, 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 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 owner in lieu of the Right
Certificate so lost, stolen, destroyed or mutilated.

               Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights.

               7.1 Exercise of Rights. Subject to Section 11.1.2 and except as
otherwise provided herein, the registered holder of any Right Certificate may
exercise the Rights evidenced thereby in whole or in part at any time after the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase and certification on the reverse side thereof duly
executed, to the Rights Agent at the office of the Rights Agent designated for
such purpose, together with payment of the aggregate Purchase Price for the
total number of one one-hundredths of a Preferred Share (or other securities,
cash or other assets) as to which the Rights are exercised, at or prior to the
time (the "Expiration Date") that is the earliest of (i) the close of business
on ________________, 2012 (the "Final Expiration Date"), (ii) the time at which
the Rights are redeemed as provided in Section 23 (the "Redemption Date"), (iii)
the closing of any merger or other acquisition transaction involving the Company
pursuant to an agreement of the type described in Section 13.3 at which time the
Rights are deemed terminated, or (iv) the time at which the Rights are exchanged
as provided in Section 27.

               7.2 Purchase. The Purchase Price for each one one-hundredth of a
Preferred Share pursuant to the exercise of a Right shall be initially
$________, shall be subject to adjustment from time to time as provided in
Sections 11, 13 and 26 and shall be payable in lawful money of the United States
of America in accordance with Section 7.3.

               7.3 Payment Procedures. Upon receipt of a Right Certificate
representing exercisable Rights, with the form of election to purchase and
certification duly executed, accompanied by payment of the aggregate Purchase
Price for the total number of one one-hundredths of a Preferred Share to be
purchased and an amount equal to any applicable transfer tax required to be paid
by the holder of such Right Certificate in accordance with Section 9, in cash or
by certified or 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 (or make available, if the Rights Agent
is the transfer agent) certificates for the number of Preferred Shares to be
purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company shall have elected to
deposit the total number of Preferred Shares issuable upon exercise of the
Rights hereunder with a depository agent, requisition from the depositary agent
depositary receipts representing interests in such number of one one-hundredths
of a Preferred Share as are to be


                                       9
<PAGE>
purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent with the depositary
agent) and the Company hereby directs the depositary agent to comply with all
such requests, (ii) when appropriate, requisition from the Company the amount of
cash to be paid in lieu of the issuance of fractional shares in accordance with
Section 14 or otherwise in accordance with Section 11.1.3, (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. In the
event that the Company is obligated to issue other securities of the Company,
pay cash and/or distribute other property pursuant to Section 11.1.3, the
Company will make all arrangements necessary so that such other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when appropriate.

               7.4 Partial Exercise. 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 and delivered to the registered
holder of such Right Certificate or to his duly authorized assigns, subject to
the provisions of Section 14.

               7.5 Full Information Concerning Ownership. Notwithstanding
anything in this Agreement to the contrary, neither the Rights Agent nor the
Company shall be obligated to undertake any action with respect to a registered
holder of Rights upon the occurrence of any purported exercise as set forth in
this Section 7 unless the certificate contained in the form of election to
purchase set forth on the reverse side of the Right Certificate surrendered for
such exercise shall have been duly completed and signed by the registered holder
thereof and the Company shall have been provided with such additional evidence
of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company shall reasonably request.

               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 canceled
form, or, if surrendered to the Rights Agent, shall be canceled 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 canceled Right Certificates to the Company, or shall, at the written request
of the Company destroy such canceled Right Certificates, and in such case shall
deliver a certificate of destruction thereof to the Company. The Company may
then destroy the Certificates after any retention period required by the
Securities and Exchange Commission.

               Section 9. Reservation and Availability of Capital Stock. The
Company covenants and agrees that from and after the Distribution Date it will
cause to be reserved and kept available out of its authorized and unissued
Preferred Shares (and, following the occurrence of a Trigger Event, out of its
authorized and unissued Common Shares or other securities or out



                                       10
<PAGE>
of its shares held in its treasury) the number of Preferred Shares (and,
following the occurrence of a Trigger Event, Common Shares and/or other
securities) that will be sufficient to permit the exercise in full of all
outstanding Rights.

               So long as the Preferred Shares (and, following the occurrence of
a Trigger Event, Common Shares and/or other securities) issuable upon the
exercise of Rights may be listed on any national securities exchange or traded
in the over-the-counter market and quoted on the National Association of
Securities Dealers, Inc. Automated Quotation System ("Nasdaq") (including the
National Market or Small Cap Market), the Company shall use its best efforts to
cause, from and after such time as the Rights become exercisable, all shares
reserved for such issuance to be listed or admitted to trading on such exchange
or quoted on Nasdaq upon official notice of issuance upon such exercise.

               The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all Preferred Shares (and, following
the occurrence of a Trigger Event, Common Shares and/or other securities)
delivered upon exercise of Rights shall, at the time of delivery of the
certificates for such shares (subject to payment of the Purchase Price), be duly
and validly authorized and issued and fully paid and nonassessable shares.

               From and after such time as the Rights become exercisable, the
Company shall use its best efforts, if then necessary to permit the issuance of
Preferred Shares upon the exercise of Rights, to register and qualify such
Preferred Shares under the Securities Act and any applicable state securities or
"Blue Sky" laws (to the extent exemptions therefrom are not available), cause
such registration statement and qualifications to become effective as soon as
possible after such filing and keep such registration and qualifications
effective until the earlier of the date as of which the Rights are no longer
exercisable for such securities and the Expiration Date. The Company may
temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file a registration
statement under the Securities Act and permit it to become effective. Upon any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained and until a registration statement
under the Securities Act (if required) shall have been declared effective.

               The Company further covenants and agrees that it will pay when
due and payable any and all Federal and state transfer taxes and charges which
may be payable in respect of the issuance or delivery of the Right Certificates
or of any Preferred Shares (or Common Shares and/or other securities, as the
case may be) upon the exercise of Rights. The Company shall not, however, be
required to pay any transfer tax 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 for the Preferred Shares (or Common Shares and/or other
securities, as the case may be) in a name other than that of, the registered
holder of the Right Certificate evidencing Rights surrendered for exercise or to
issue or deliver any certificates for Preferred Shares (or Common Shares and/or
other securities, as the case may be) in a name other than that of the
registered holder upon the exercise of any Rights until any such tax shall have
been paid (any such tax being payable by the


                                       11
<PAGE>
holder of such Right Certificate at the time of surrender) or until it has been
established to the Company's satisfaction that no such tax is due.

               Section 10. Preferred Shares Record Date. Each person in whose
name any certificate for Preferred Shares (or Common Shares and/or other
securities, as the case may be) is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares (or Common Shares and/or other securities, as the case may be)
represented thereby on, and 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 taxes) was made; PROVIDED,
HOWEVER, that if the date of such surrender and payment is a date upon which the
Preferred Shares (or Common Shares and/or other securities, as the case may be)
transfer books of the Company are closed, such person shall be deemed to have
become the record holder of such shares (fractional or otherwise) on, and such
certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares (or Common Shares and/or other securities, as the case may be)
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 or to receive
dividends or other distributions, 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 or other
securities or property purchasable upon exercise of each Right and the number of
Rights outstanding are subject to adjustment from time to time as provided in
this Section 11.

               11.1 Post-Execution Events.

               11.1.1 Corporate Dividends, Reclassifications, Etc. In the event
the Company shall at any time after the date of this Agreement (A) declare and
pay 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 11.1, 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, 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, he 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. If an event occurs which would require an
adjustment under both Section 11.1.1 and Section 11.1.2, the adjustment provided
for


                                       12
<PAGE>
in this Section 11.1.1 shall be in addition to, and shall be made prior to, the
adjustment required pursuant to, Section 11.1.2.

               11.1.2 Acquiring Person Events; Triggering Events. Subject to
Sections 23.1 and 27, in the event that a Trigger Event occurs, then, from and
after the first occurrence of such event, each holder of a Right, except as
provided below, shall thereafter have a right to receive, upon exercise thereof
at a price per Right 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 (without giving effect to this Section 11.1.2), in accordance with
the terms of this Agreement and in lieu of Preferred Shares, such number of
Common Shares as shall equal the result obtained by (x) multiplying the then
current Purchase Price by the then number of one one-hundredths of a Preferred
Share for which a Right is then exercisable (without giving effect to this
Section 11.1.2) and (y) dividing that product by 50% of the current per share
market price of the Common Shares (determined pursuant to Section 11.4) on the
first of the date of the occurrence of, or the date of the first public
announcement of, a Trigger Event (the "Adjustment Shares"); PROVIDED that the
Purchase Price and the number of Adjustment Shares shall thereafter be subject
to further adjustment as appropriate in accordance with Section 11.6.
Notwithstanding the foregoing, upon the occurrence of a Trigger Event, any
Rights that are or were acquired or beneficially owned by (1) any Acquiring
Person or any Associate or Affiliate thereof, (2) a transferee of any Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee after
the Acquiring Person becomes such, or (3) a transferee of any Acquiring Person
(or of any such Associate or Affiliate) who becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which the Board of Directors of the Company has determined is part of a plan,
arrangement or understanding which has as a primary purpose or effect avoidance
of this Section 11.1.2, and subsequent transferees, shall become void without
any further action, and any holder (whether or not such holder is an Acquiring
Person or an Associate or Affiliate of an Acquiring Person) of such Rights shall
thereafter have no right to exercise such Rights under any provision of this
Agreement or otherwise. From and after the Trigger Event, no Right Certificate
shall be issued pursuant to Section 3 or Section 6 that represents Rights that
are or have become void pursuant to the provisions of this paragraph, and any
Right Certificate delivered to the Rights Agent that represents Rights that are
or have become void pursuant to the provisions of this paragraph shall be
canceled.

               The Company shall use all reasonable efforts to ensure that the
provisions of this Section 11.1.2 are complied with, but shall have no liability
to any holder of Right Certificates or other Person as a result of its failure
to make any determinations with respect to any Acquiring Person or its
Affiliates, Associates or transferees hereunder.

               From and after the occurrence of an event specified in Section
13.1, any Rights that theretofore have not been exercised pursuant to this
Section 11.1.2 shall thereafter be exercisable only in accordance with Section
13 and not pursuant to this Section 11.1.2.



                                       13
<PAGE>
               11.1.3 Insufficient Shares. The Company may at its option
substitute for a Common Share issuable upon the exercise of Rights in accordance
with the foregoing Section 11.1.2 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. In the event that upon the occurrence of a Trigger
Event there shall not be sufficient Common Shares authorized but unissued, or
held by the Company as treasury shares, to permit the exercise in full of the
Rights in accordance with the foregoing Section 11.1.2, the Company shall take
all such action as may be necessary to authorize additional Common Shares for
issuance upon exercise of the Rights, PROVIDED, HOWEVER, that if the Company
determines that it is unable to cause the authorization of a sufficient number
of additional Common Shares, then, in the event the Rights become exercisable,
the Company, with respect to each Right and to the extent necessary and
permitted by applicable law and any agreements or instruments in effect on the
date hereof to which it is a party, shall: (A) determine the excess of (1) the
value of the Adjustment Shares issuable upon the exercise of a Right (the
"Current Value"), over (2) the Purchase Price (such excess, the "Spread") and
(B) with respect to each Right (other than Rights which have become void
pursuant to Section 11.1.2), make adequate provision to substitute for the
Adjustment Shares, upon payment of the applicable Purchase Price, (1) cash, (2)
a reduction in the Purchase Price, (3) Preferred Shares or other equity
securities of the Company (including, without limitation, shares, or fractions
of shares, of preferred stock which, by virtue of having dividend and
liquidation rights substantially comparable to those of the Common Shares, the
Board of Directors of the Company has deemed in good faith to have substantially
the same value as Common Shares) (each such share of preferred stock or
fractions of shares of preferred stock constituting a "common stock
equivalent")), (4) debt securities of the Company, (5) other assets or (6) any
combination of the foregoing having an aggregate value equal to the Current
Value, where such aggregate value has been determined by the Board of Directors
of the Company based upon the advice of a nationally recognized investment
banking firm selected in good faith by the Board of Directors of the Company;
PROVIDED, HOWEVER, that if the Company shall not have made adequate provision to
deliver value pursuant to clause (B) above within thirty (30) days following the
occurrence of a Trigger Event, then the Company shall be obligated to deliver,
to the extent necessary and permitted by applicable law and any agreements or
instruments in effect on the date hereof to which it is a party, upon the
surrender for exercise of a Right and without requiring payment of the Purchase
Price, Common Shares (to the extent available) and then, if necessary, such
number or fractions of Preferred Shares (to the extent available) and then, if
necessary, cash, which shares and/or cash have an aggregate value equal to the
Spread. If the Board of Directors of the Company shall determine in good faith
that it is unlikely that sufficient additional Common Shares could be authorized
for issuance upon exercise in full of the Rights, the thirty (30) day period set
forth above may be extended and re-extended to the extent necessary, but not
more than ninety (90) days following the occurrence of a Trigger Event, in order
that the Company may seek stockholder approval for the authorization of such
additional shares (such period as may be extended, the "Substitution Period").
To the extent that the Company determines that some action need be taken
pursuant to the second and/or third sentences of this Section 11.1.3, the
Company (x) shall provide that such action shall apply uniformly to all
outstanding Rights, and (y) may suspend the exercisability of the Rights until
the expiration of the Substitution Period in order to seek any authorization of
additional shares and/or to decide the appropriate form of distribution to be
made pursuant to


                                       14
<PAGE>
such first sentence and to determine the value thereof. In the event of any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended as well as a public
announcement at such time as the suspension is no longer in effect. For purposes
of this Section 11.1.3, the value of a Common Share shall be the current per
share market price (as determined pursuant to Section 11.4) on the date of the
occurrence of a Trigger Event and the value of any "common stock equivalent"
shall be deemed to have the same value as the Common Shares on such date. The
Board of Directors of the Company may, but shall not be required to, establish
procedures to allocate the right to receive Common Shares upon the exercise of
the Rights among holders of Rights pursuant to this Section 11.1.3.

               11.2 Dilutive Rights Offering. 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
securities having the same rights, privileges and preferences as the Preferred
Shares ("equivalent preferred stock")) or securities convertible into Preferred
Shares or equivalent preferred stock at a price per Preferred Share or per share
of equivalent preferred stock (or having a conversion or exercise price per
share, if a security convertible into or exercisable for Preferred Shares or
equivalent preferred stock) less than the current per share market price of the
Preferred Shares (as determined pursuant to Section 11.4) 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
and shares of equivalent preferred stock outstanding on such record date plus
the number of Preferred Shares and shares of equivalent preferred stock which
the aggregate offering price of the total number of Preferred Shares and/or
shares of equivalent preferred stock to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such current per share market price and the denominator of which shall be the
number of Preferred Shares and shares of equivalent preferred stock outstanding
on such record date plus the number of additional Preferred Shares and/or shares
of equivalent preferred stock 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 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 binding on the Rights Agent and the holders of the Rights. Preferred
Shares and shares of equivalent preferred stock owned by or held for the account
of the Company or any Subsidiary of the Company shall not be deemed outstanding
for the purpose of any such computation. Such adjustments shall be made
successively whenever such a record date is fixed; and in the event that such
rights 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.

               11.3 Distributions. 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


                                       15
<PAGE>
corporation) of evidences of indebtedness, cash, securities or assets (other
than a regular periodic cash dividend at a rate not in excess of 125% of the
rate of the last regular periodic cash dividend theretofore paid or, in case
regular periodic cash dividends have not theretofore been paid, at a rate not in
excess of 50% of the average net income per share of the Company for the four
quarters ended immediately prior to the payment of such dividend, or a dividend
payable in Preferred Shares (which dividend, for purposes of this Agreement,
shall be subject to the provisions of Section 11.1.1(A))) or convertible
securities, or subscription rights or warrants (excluding those referred to in
Section 11.2), 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 current per
share market price of the Preferred Shares (as determined pursuant to Section
11.4) 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) of the portion of the
cash, assets, securities 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 current per share market price of the
Preferred Shares (as determined pursuant to Section 11.4); 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.

               11.4 Current Per Share Market Value.

               11.4.1 General. For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11.4.1) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days (as such term is 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 any period following the announcement
by the issuer of such Security of (i) a dividend or distribution on such
Security payable in shares of such Security or securities convertible into such
shares or (ii) any subdivision, combination or reclassification of such
Security, and prior to the expiration of thirty (30) Trading Days after 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, or, in case no such sale
takes place on such day, the average of the closing bid 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 Security is 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 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 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



                                       16
<PAGE>
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. If on any such date no such market maker is making a market in the
Security, the fair value of the Security on such date as determined in good
faith by the Board of Directors of the Company shall be used. 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. If the Security is not publicly
held or not so listed or traded, or if on any such date the Security is not so
quoted and no such market maker is making a market in the Security, "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 or, if at the time of such
determination there is an Acquiring Person, by a nationally recognized
investment banking firm selected by the Board of Directors, which shall have the
duty to make such determination in a reasonable and objective manner, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

               11.4.2 Preferred Shares. Notwithstanding Section 11.4.1, for the
purpose of any computation hereunder, the "current per share market price" of
the Preferred Shares shall be determined in the same manner as set forth above
in Section 11.4.1 (other than the last sentence thereof). If the current per
share market price of the Preferred Shares cannot be determined in the manner
described in Section 11.4.1, the "current per share market price" of the
Preferred Shares shall be conclusively deemed to be an amount equal to 100 (as
such number may be appropriately adjusted for such events as stock splits, stock
dividends and recapitalizations with respect to the Common Shares occurring
after the date of this Agreement) multiplied by the current per share market
price of the Common Shares (as determined pursuant to Section 11.4.1). If
neither the Common Shares nor the Preferred Shares are publicly held or so
listed or traded, or if on any such date neither the Common Shares nor the
Preferred Shares are so quoted and no such market maker is making a market in
either the Common Shares or the Preferred Shares, "current per share market
price" of the Preferred Shares shall mean the fair value per share as determined
in good faith by the Board of Directors of the Company, or, if at the time of
such determination there is an Acquiring Person, by a nationally recognized
investment banking firm selected by the Board of Directors of the Company, which
shall have the duty to make such determination in a reasonable and objective
manner, which determination shall be described in a statement filed with the
Rights Agent and shall be conclusive for all purposes. For purposes of this
Agreement, the "current per share market price" of one one-hundredth of a
Preferred Share shall be equal to the "current per share market price" of one
Preferred Share divided by 100.

               11.5 Insignificant Changes. 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. Any adjustments which by reason of this
Section 11.5 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-hundred thousandth of a
Preferred Share or the nearest one-hundredth of a Common Share or other share or
security, as the case may be.



                                       17

               11.6 Shares Other Than Preferred Shares. If as a result of an
adjustment made pursuant to Section 11.1, 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 Sections 11.1,
11.2, 11.3, 11.5, 11.8, 11.9 and 11.13, and the provisions of Sections 7, 9, 10,
13 and 14 with respect to the Preferred Shares shall apply on like terms to any
such other shares.

               11.7 Rights Issued Prior to Adjustment. 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.

               11.8 Effect of Adjustments. Unless the Company shall have
exercised its election as provided in Section 11.9, upon each adjustment of the
Purchase Price as a result of the calculations made in Sections 11.2 and 11.3,
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-hundred thousandth of a Preferred Share) obtained by (i) multiplying (x) the
number of one one-hundredths of a Preferred 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 (ii) dividing the product so
obtained by the Purchase Price in effect immediately after such adjustment of
the Purchase Price.

               11.9 Adjustment in Number of Rights. 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 issuable 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-hundredth) 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. 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 least ten (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
11.9, the Company may, 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, 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


                                       18
<PAGE>
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 may bear, at the option of the Company, the
adjusted Purchase Price) and shall be registered in the names of the holders of
record of Right Certificates on the record date specified in the public
announcement.

               11.10 Right Certificates Unchanged. Irrespective of any
adjustment or change in the Purchase Price or 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 per share and the number of one one-hundredths of a Preferred
Share which were expressed in the initial Right Certificates issued hereunder.

               11.11 Par Value Limitations. 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 or other shares of capital stock
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 or other such shares at such adjusted Purchase Price.

               11.12 Deferred Issuance. 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 until the
occurrence of such event the issuance to the holder of any Right exercised after
such record date of that number of Preferred Shares and shares of other capital
stock or securities of the Company, if any, issuable upon such exercise over and
above the Preferred Shares and shares of other capital stock or other
securities, assets or cash 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.

               11.13 Reduction in Purchase Price. 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 of the 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 hereinabove in this
Section 11, hereafter made by the Company to holders of its Preferred Shares
shall not be taxable to such stockholders.

               11.14 Company Not to Diminish Benefits of Rights. The Company
covenants and agrees that after the earlier of the Shares Acquisition Date or
Distribution Date it will not, except as permitted by Section 23, Section 26 or
Section 27, take (or permit any Subsidiary to take) any action if at the time
such action is taken it is reasonably foreseeable that such action will
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights.

               11.15 Adjustment of Rights Associated with Common Shares.
Notwithstanding anything contained in this Agreement to the contrary, in the
event that the Company shall at any time after the date hereof and prior to the
Distribution Date (i) declare or pay any dividend on the outstanding Common
Shares payable in Common Shares, (ii) effect a subdivision or consolidation of
the outstanding Common Shares (by reclassification or otherwise than by the
payment of dividends payable in Common Shares), or (iii) combine the outstanding
Common Shares into a greater or lesser number of Common Shares, then in any such
case, the number of Rights associated with each Common Share then outstanding,
or issued or delivered thereafter but prior to the Distribution Date or in
accordance with Section 22 shall be proportionately adjusted so that the number
of Rights thereafter associated with each Common Share following any such event
shall equal the result obtained by multiplying the number of Rights associated
with each Common Share immediately prior to such event by a fraction, the
numerator of which shall be the total number of Common Shares outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of Common Shares outstanding immediately following the
occurrence of such event. The adjustments provided for in this Section 11.15
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 Sections 11 or 13, the
Company shall (a) promptly prepare a certificate setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) promptly
file with the Rights Agent and with each transfer agent for the Common Shares or
the Preferred Shares a copy of such certificate and (c) mail a brief summary
thereof to each holder of a Right Certificate in accordance with Section 25. The
Rights Agent shall be fully protected in relying on any such certificate and on
any adjustment therein contained and shall not be deemed to have knowledge of
any such adjustment unless and until it shall have received such certificate.

               Section 13. Consolidation, Merger or Sale or Transfer of Assets
or Earning Power.

               13.1 Certain Transactions. In the event that, from and after the
first occurrence of a Trigger Event, directly or indirectly, (A) the Company
shall consolidate with, or merge with and into, any other Person and the Company
shall not be the continuing or surviving corporation, (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 the Company or any other
Person or cash or any other property, or (C) the Company shall sell, exchange,
mortgage or otherwise transfer (or one or more of its Subsidiaries shall sell,
exchange, mortgage 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 or Persons
(other than the Company or one or more wholly-owned Subsidiaries of the Company
in one or more transactions each of which complies with Section 11.14), then,
and in each such case, proper provision shall be made so that (i) each holder of
a Right (other than Rights which have become void pursuant to Section 11.1.2)
shall thereafter have the right to receive, upon the exercise thereof at a price
per Right equal to the then current Purchase Price multiplied by the number of
one one-hundredths of a Preferred



                                       20
<PAGE>
Share for which a Right was exercisable immediately prior to the first
occurrence of a Trigger Event (as subsequently adjusted pursuant to Sections
11.1.1, 11.2, 11.3, 11.8, 11.9 and 11.12), in accordance with the terms of this
Agreement and in lieu of Preferred Shares or Common Shares, such number of
validly authorized and issued, fully paid, non-assessable and freely tradable
Common Shares of the Principal Party (as such term is hereinafter defined) not
subject to any liens, encumbrances, rights of first refusal or other adverse
claims, as shall be equal to the result obtained by (x) multiplying the then
current Purchase Price by the number of one one-hundredths of a Preferred Share
for which a Right was exercisable immediately prior to the first occurrence of a
Trigger Event (as subsequently adjusted pursuant to Sections 11.1.1, 11.2, 11.3,
11.8, 11.9 and 11.12) and (y) dividing that product by 50% of the then current
per share market price of the Common Shares of such Principal Party (determined
pursuant to Section 11.4) on the date of consummation of such consolidation,
merger, sale or transfer; PROVIDED, that the price per Right so payable and the
number of Common Shares of such Principal Party so receivable upon exercise of a
Right shall thereafter be subject to further adjustment as appropriate in
accordance with Section 11.6 to reflect any events covered thereby occurring in
respect of the Common Shares of such Principal Party after the occurrence of
such consolidation, merger, sale or transfer; (ii) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such consolidation,
merger, sale or transfer, all the obligations and duties of the Company pursuant
to this Agreement; (iii) the term "Company" shall thereafter be deemed to refer
to such Principal Party; and (iv) such Principal Party shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
Common Shares in accordance with Section 9) 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 its Common Shares
thereafter deliverable upon the exercise of the Rights; PROVIDED that, upon the
subsequent occurrence of any consolidation, merger, sale or transfer of assets
or other extraordinary transaction in respect of such Principal Party, each
holder of a Right shall thereupon be entitled to receive, upon exercise of a
Right and payment of the Purchase Price as provided in this Section 13.1, such
cash, shares, rights, warrants and other property which such holder would have
been entitled to receive had such holder, at the time of such transaction, owned
the Common Shares of the Principal Party receivable upon the exercise of a Right
pursuant to this Section 13.1, and such Principal Party shall take such steps
(including, but not limited to, reservation of shares of stock) as may be
necessary to permit the subsequent exercise of the Rights in accordance with the
terms hereof for such cash, shares, rights, warrants and other property. The
Company shall not consummate any such consolidation, merger, sale or transfer
unless prior thereto the Company and such Principal Party shall have executed
and delivered to the Rights Agent a supplemental agreement confirming that the
requirements of this Section 13.1 and Section 13.2 shall promptly be performed
in accordance with their terms and that such consolidation, merger, sale or
transfer of assets shall not result in a default by the Principal Party under
this Agreement as the same shall have been assumed by the Principal Party
pursuant to this Section 13.1 and Section 13.2 and providing that, as soon as
practicable after executing such agreement pursuant to this Section 13, the
Principal Party, at its own expense, shall:

               (1) prepare and file a registration statement under the
Securities Act, if necessary, with respect to the Rights and the securities
purchasable upon exercise of the Rights on an appropriate form, use its best
efforts to cause such registration statement to become effective as soon as
practicable after such filing and use its best efforts to cause such
registration statement to remain effective (with a prospectus at all times
meeting the requirements of the



                                       21
<PAGE>
Securities Act) until the Expiration Date and similarly comply with applicable
state securities laws;

               (2) use its best efforts, if the Common Shares of the Principal
Party shall be listed or admitted to trading on the New York Stock Exchange or
on another national securities exchange, to list or admit to trading (or
continue the listing of) the Rights and the securities purchasable upon exercise
of the Rights on the New York Stock Exchange or such securities exchange, or, if
the Common Shares of the Principal Party shall not be listed or admitted to
trading on the New York Stock Exchange or a national securities exchange, to
cause the Rights and the securities receivable upon exercise of the Rights to be
authorized for quotation on Nasdaq or on such other system then in use;

               (3) deliver to holders of the Rights historical financial
statements for the Principal Party which comply in all respects with the
requirements for registration on Form 10 (or any successor form) under the
Exchange Act; and

               (4) obtain waivers of any rights of first refusal or preemptive
rights in respect of the Common Shares of the Principal Party subject to
purchase upon exercise of outstanding Rights.

               In case the Principal Party has provision in any of its
authorized securities or in its certificate of incorporation or by-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue (other than to holders of
Rights pursuant to this Section 13), in connection with, or as a consequence of,
the consummation of a transaction referred to in this Section 13, Common Shares
or common stock equivalents of such Principal Party at less than the then
current market price per share thereof (determined pursuant to Section 11.4) or
securities exercisable for, or convertible into, Common Shares or common stock
equivalents of such Principal Party at less than such then current market price
(other than to holders of Rights pursuant to this Section 13), or (ii) providing
for any special payment, taxes or similar provision in connection with the
issuance of the Common Shares of such Principal Party pursuant to the provision
of Section 13, then, in such event, the Company hereby agrees with each holder
of Rights that it shall not consummate any such transaction unless prior thereto
the Company and such Principal Party shall have executed and delivered to the
Rights Agent a supplemental agreement providing that the provision in question
of such Principal Party shall have been canceled, waived or amended, or that the
authorized securities shall be redeemed, so that the applicable provision will
have no effect in connection with, or as a consequence of, the consummation of
the proposed transaction.

               The Company covenants and agrees that it shall not, at any time
after the Trigger Event, enter into any transaction of the type described in
clauses (A) through (C) of this Section 13.1 if (i) at the time of or
immediately after such consolidation, merger, sale, transfer or other
transaction there are any rights, warrants or other instruments or securities
outstanding or agreements in effect which would substantially diminish or
otherwise eliminate the benefits intended to be afforded by the Rights, (ii)
prior to, simultaneously with or immediately after such consolidation, merger,
sale, transfer or other transaction, the stockholders of the Person who
constitutes, or would constitute, the Principal Party for purposes of Section
13.2 shall have received a distribution of Rights previously owned by such
Person or any of its Affiliates or



                                       22
<PAGE>
Associates or (iii) the form or nature of organization of the Principal Party
would preclude or limit the exercisability of the Rights. The provisions of this
Section 13 shall similarly apply to successive transactions of the type
described in clauses (A) through (C) of this Section 13.1.

               13.2   Principal Party.  "Principal Party" shall mean:

                      (i) in the case of any transaction described in (A) or (B)
of the first sentence of Section 13.1: (i) the Person that is the issuer of the
securities into which the Common Shares are converted in such merger or
consolidation, or, if there is more than one such issuer, the issuer the Common
Shares of which have the greatest aggregate market value of shares outstanding,
or (ii) if no securities are so issued, (x) the Person that is the other party
to the merger, if such Person survives said merger, or, if there is more than
one such Person, the Person the Common Shares of which have the greatest
aggregate market value of shares outstanding or (y) if the Person that is the
other party to the merger does not survive the merger, the Person that does
survive the merger (including the Company if it survives) or (z) the Person
resulting from the consolidation; and

                      (ii) in the case of any transaction described in (C) of
the first sentence in Section 13.1, the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to such
transaction or transactions, or, if each Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power so transferred or if the Person receiving the greatest portion of the
assets or earning power cannot be determined, whichever of such Persons is the
issuer of Common Shares having the greatest aggregate market value of shares
outstanding; PROVIDED, HOWEVER, that in any such case described in the foregoing
clause (i) or (ii) of this Section 13.2, if the Common Shares of such Person are
not at such time or have not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, then (1) if such Person
is a direct or indirect Subsidiary of another Person the Common Shares of which
are and have been so registered, the term "Principal Party" shall refer to such
other Person, or (2) if such Person is a Subsidiary, directly or indirectly, of
more than one Person, the Common Shares of all of which are and have been so
registered, the term "Principal Party" shall refer to whichever of such Persons
is the issuer of Common Shares having the greatest aggregate market value of
shares outstanding, or (3) if such Person is owned, directly or indirectly, by a
joint venture formed by two or more Persons that are not owned, directly or
indirectly, by the same Person, the rules set forth in clauses (1) and (2) above
shall apply to each of the owners having an interest in the venture as if the
Person owned by the joint venture was a Subsidiary of both or all of such joint
venturers, and the Principal Party in each such case shall bear the obligations
set forth in this Section 13 in the same ratio as its interest in such Person
bears to the total of such interests.

               13.3 Approved Acquisitions. Notwithstanding anything contained
herein to the contrary, upon the consummation of any merger or other acquisition
transaction of the type described in clause (A), (B) or (C) of Section 13.1
involving the Company pursuant to a merger or other acquisition agreement
between the Company and any Person (or one or more of such Person's Affiliates
or Associates) which agreement has been approved by the Board of Directors of
the Company prior to any Person becoming an Acquiring Person, this Agreement and
the rights of holders of Rights hereunder shall be terminated in accordance with
Section 7.1.

               Section 14. Fractional Rights and Fractional Shares.

               14.1 Cash in Lieu of Fractional Rights. The Company shall not be
required to issue fractions of Rights or to distribute Right Certificates which
evidence fractional Rights (except prior to the Distribution Date in accordance
with Section 11.15). 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 14.1, 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 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 current market
value of the Rights on such date shall be the fair value of the Rights as
determined in good faith by the Board of Directors of the Company, or, if at the
time of such determination there is an Acquiring Person, by a nationally
recognized investment banking firm selected by the Board of Directors of the
Company, which shall have the duty to make such determination in a reasonable
and objective manner, which determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes.

               14.2 Cash in Lieu of Fractional Preferred Shares. 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 or exchange 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). Interests in
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 integral 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 or exchanged as herein provided an amount in
cash equal to the same fraction of the current per share market price of one
Preferred Share (as determined in accordance with Section 14.1) for the Trading
Day immediately prior to the date of such exercise or exchange.



                                       24
<PAGE>
               14.3 Cash in Lieu of Fractional Common Shares. The Company shall
not be required to issue fractions of Common Shares or to distribute
certificates which evidence fractional Common Shares upon the exercise or
exchange of Rights. 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
(as determined in accordance with Section 14.1) for the Trading Day immediately
prior to the date of such exercise or exchange.

               14.4 Waiver of Right to Receive Fractional Rights or Shares. The
holder of a Right by the acceptance of the Rights expressly waives his right to
receive any fractional Rights or any fractional shares upon exercise or exchange
of a Right, except as permitted by this Section 14.

               Section 15. Rights of Action. All rights of action in respect of
this Agreement, except the rights of action given to the Rights Agent under
Section 18, 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
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 his own behalf and for his own
benefit, enforce this Agreement, and may institute and maintain any suit, action
or proceeding against the Company to enforce this Agreement, or otherwise
enforce or act in respect of his 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 of this Agreement and
shall be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of, the obligations of
any Person (including, without limitation, the Company) 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) as of and 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 with all required certifications completed; 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 (notwithstanding any notations of ownership or writing on the
        Right Certificates or the associated Common Shares certificate made by
        anyone other than the



                                       25
<PAGE>
        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.

               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 24), 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 in accordance with a fee schedule to be mutually agreed upon and, from
time to time, on demand of the Rights Agent, its reasonable expenses and counsel
fees and other disbursements incurred in the administration and execution 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, or expense, incurred without negligence, bad faith
or willful misconduct on the part of the Rights Agent, for anything done or
omitted by the Rights Agent in connection with the acceptance and administration
of this Agreement, including the costs and expenses of defending against any
claim of liability arising therefrom, directly or indirectly.

               The Rights Agent shall be protected and shall incur no liability
for or in respect of any action taken, suffered or omitted by it in connection
with its administration of this Agreement in reliance upon any Right Certificate
or certificate for the Preferred Shares or the Common Shares or for other
securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, instruction, 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 Persons.

               Section 19. Merger or Consolidation or Change of Name of Rights
Agent. Any corporation or limited liability company into which the Rights Agent
or any successor Rights Agent may be merged or with which it may be
consolidated, or any corporation or limited liability company resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any corporation or limited liability company succeeding to
the corporate trust or stock transfer 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 corporation or limited
liability company would be eligible for appointment as a successor Rights Agent
under the provisions of Section 21. 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 and
deliver such Right


                                       26
<PAGE>
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
the duties and obligations imposed by this Agreement 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:

               20.1 Legal Counsel. The Rights Agent may consult with legal
counsel selected by it (who may be legal counsel for the Company), and the
opinion of such counsel shall be full and complete authorization and protection
to the Rights Agent as to any action taken or omitted by it in good faith and in
accordance with such opinion.

               20.2 Certificates as to Facts or Matters. Whenever in the
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 or suffering 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 of Directors, the Chief Executive Officer,
the President, the Chief Financial Officer, any Vice President, the Treasurer,
the Secretary or any Assistant Treasurer or Assistant Secretary of the Company
and delivered to the Rights Agent; and such certificate shall be full
authorization to the Rights Agent for any action taken or suffered in good faith
by it under the provisions of this Agreement in reliance upon such certificate.

               20.3 Standard of Care. The Rights Agent shall be liable hereunder
only for its own gross negligence, bad faith or willful misconduct.

               20.4 Reliance on Agreement and Right Certificates. 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 as to
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.

               20.5 No Responsibility as to Certain Matters. The Rights Agent
shall not be under any responsibility in respect of the validity of this
Agreement or the execution and delivery hereof (except the due execution hereof
by the Rights Agent) or in respect of the



                                       27
<PAGE>
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be 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 responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 11.1.2) or any
adjustment required under the provisions of Sections 3, 11, 13, 23 or 27 or
responsible for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such adjustment
(except with respect to the exercise of Rights evidenced by Right Certificates
after actual notice of any such change or adjustment); 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 or other securities to be
issued pursuant to this Agreement or any Right Certificate or as to whether any
Preferred Shares will, when so issued, be validly authorized and issued, fully
paid and nonassessable.

               20.6 Further Assurance by Company. 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 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.

               20.7 Authorized Company Officers. The Rights Agent is hereby
authorized and directed to accept instructions with respect to the performance
of its duties hereunder from any one of the Chairman of the Board of Directors,
the Chief Executive Officer, the President, the Chief Financial Officer, any
Vice President, the Treasurer, the Secretary or any Assistant Treasurer or
Assistant Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties under this Agreement, and it shall
not be liable for any action taken or suffered to be taken by it in good faith
in accordance with instructions of any such officer or for any delay in acting
while waiting for these instructions. Any application by the Rights Agent for
written instructions from the Company may, at the option of the Rights Agent,
set forth in writing any action proposed to be taken or omitted by the Rights
Agent with respect to its duties or obligations under this Agreement and the
date on and/or after which such action shall be taken or such omission shall be
effective. The Rights Agent shall not be liable to the Company for any action
taken by, or omission of, the Rights Agent in accordance with a proposal
included in any such application on or after the date specified therein (which
date shall not be less than three business days after the date any such officer
actually receives such application, unless any such officer shall have consented
in writing to an earlier date) unless, prior to taking of any such action (or
the effective date in the case of omission), the Rights Agent shall have
received written instructions in response to such application specifying the
action to be taken or omitted.

               20.8 Freedom to Trade in Company Securities. The Rights Agent and
any stockholder, 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 from acting in any other capacity
for the Company or for any other legal entity.


                                       28
<PAGE>
               20.9 Reliance on Attorneys and Agents. The Rights Agent may
execute and exercise any of the rights or powers hereby vested in it or perform
any duty hereunder either itself or by or through its attorneys or agents, and
the Rights Agent shall not be answerable or accountable for any act, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss
to the Company resulting from any such act, omission, default, neglect or
misconduct, PROVIDED that reasonable care was exercised in the selection and
continued employment thereof.

               20.10 Incomplete Certificate. If, with respect to any Rights
Certificate surrendered to the Rights Agent for exercise or transfer, the
certificate contained in the form of assignment or the form of election to
purchase set forth on the reverse thereof, as the case may be, has not been
completed to certify the holder is not an Acquiring Person (or an Affiliate or
Associate thereof), the Rights Agent shall not take any further action with
respect to such requested exercise or transfer without first consulting with the
Company.

               20.11 Rights Holders List. At any time and from time to time
after the Distribution Date, upon the request of the Company, the Rights Agent
shall promptly deliver to the Company a list, as of the most recent practicable
date (or as of such earlier date as may be specified by the Company), of the
holders of record of Rights.

               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 thirty (30) days' notice in writing mailed to the Company and to
each transfer agent of the Common Shares and/or Preferred Shares, as applicable,
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 thirty (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 and/or Preferred Shares, as applicable, 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 resigning, removed, or incapacitated Rights Agent shall
remit to the Company, or to any successor Rights Agent designated by the
Company, all books, records, funds, certificates or other documents or
instruments of any kind then in its possession which were acquired by such
resigning, removed or incapacitated Rights Agent in connection with its services
as Rights Agent hereunder, and shall thereafter be discharged from all duties
and obligations hereunder. Following notice of such removal, resignation or
incapacity, the Company shall appoint a successor to such Rights Agent. If the
Company shall fail to make such appointment within a period of thirty (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 (who shall, with such notice, submit his
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 corporation organized and doing
business under the laws of the United States or of the State of New York or the
State of California (or any other state of the United States so long as such
corporation is authorized to do business as a banking institution in the State
of New York or California) in good standing, having an office in the State of
New York or the State of



                                       29
<PAGE>
California, which is authorized under such laws to exercise stock transfer or
corporate trust powers and is subject to supervision or examination by Federal
or state authority and which has at the time of its appointment as Rights Agent
a combined capital and surplus of at least $10 million. 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 Rights Agent
and each transfer agent of the Common Shares and/or Preferred Shares, as
applicable, and, following the Distribution Date, 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 its Board of Directors 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. In addition, in connection
with the issuance or sale of Common Shares following the Distribution Date and
prior to the Expiration Date, the Company shall, with respect to Common Shares
so issued or sold pursuant to the exercise of stock options or under any
employee plan or arrangement, granted or awarded, or upon exercise, conversion
or exchange of securities hereinafter issued by the Company, in each case
existing prior to the Distribution Date, issue Right Certificates representing
the appropriate number of Rights in connection with such issuance or sale;
PROVIDED, HOWEVER, that (i) no such Right Certificate shall be issued if, and to
the extent that, the Company shall be advised by counsel that such issuance
would create a significant risk of material adverse tax consequences to the
Company or the Person to whom such Right Certificate would be issued and (ii) no
such Right Certificate shall be issued if, and to the extent that, appropriate
adjustment shall otherwise have been made in lieu of the issuance thereof.

               Section 23. Redemption.

               23.1 Right to Redeem. The Board of Directors of the Company may,
at its option, at any time prior to a Trigger Event, redeem all but not less
than all of the then outstanding Rights at a redemption price of $.01 per Right,
appropriately adjusted to reflect any stock split, stock dividend,
recapitalization or similar transaction occurring after the date hereof (such
redemption price being hereinafter referred to as the "Redemption Price"), and
the Company may, at its option, pay the Redemption Price in Common Shares (based
on the "current per share market price," determined pursuant to Section 11.4, of
the Common Shares at the time of redemption), cash or any other form of
consideration deemed appropriate by the Board of Directors. The redemption of
the Rights by the Board of Directors may be made effective at such time, on such
basis and subject to such conditions as the Board of Directors in its sole
discretion may establish.



                                       30
<PAGE>
               23.2 Redemption Procedures. Immediately upon the action of the
Board of Directors of the Company ordering the redemption of the Rights (or at
such later time as the Board of Directors may establish for the effectiveness of
such redemption), and without any further action and without any notice, the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the Redemption Price for each Right so
held. The Company shall promptly give public notice of such redemption;
PROVIDED, HOWEVER, that the failure to give, or any defect in, any such notice
shall not affect the validity of such redemption. The Company shall promptly
give, or cause the Rights Agent to give, notice of such redemption to the
holders of the then outstanding Rights by mailing such notice to all such
holders 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 shall 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 27, and other than in connection with the purchase, acquisition or
redemption of Common Shares prior to the Distribution Date.

               Section 24. Notice of Certain Events. In case the Company shall
propose at any time after the earlier of the Shares Acquisition Date and the
Distribution Date (a) to pay any dividend payable in stock of any class to the
holders of Preferred Shares or to make any other distribution to the holders of
Preferred Shares (other than a regular periodic cash dividend at a rate not in
excess of 125% of the rate of the last regular periodic cash dividend
theretofore paid or, in case regular periodic cash dividends have not
theretofore been paid, at a rate not in excess of 50% of the average net income
per share of the Company for the four quarters ended immediately prior to the
payment of such dividends, or a stock dividend on, or a subdivision, combination
or reclassification of the Common Shares), or (b) to offer to the holders of
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, or (c) to effect any reclassification of its
Preferred Shares (other than a reclassification involving only the subdivision
of outstanding Preferred Shares), or (d) to effect any consolidation or merger
into or with, or to effect 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 (other than pursuant to
a merger or other acquisition agreement of the type described in Section
1.3(ii)(A)(z)), or (e) to effect the liquidation, dissolution or winding up of
the Company, or (f) 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 25,
a notice of such proposed action, which shall specify the record date for the
purposes of such stock dividend, 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 Preferred Shares and/or Common
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 (a) or (b) above at least ten (10) days
prior to the record date for



                                       31
<PAGE>
determining holders of the Preferred Shares for purposes of such action, and in
the case of any such other action, at least ten (10) days prior to the date of
the taking of such proposed action or the date of participation therein by the
holders of the Preferred Shares and/or Common Shares, whichever shall be the
earlier.

               In case any event set forth in Section 11.1.2 or Section 13 shall
occur, then, in any such case, (i) the Company shall as soon as practicable
thereafter give to the Rights Agent and to each holder of a Right Certificate,
in accordance with Section 25, a notice of the occurrence of such event, which
notice shall describe the event and the consequences of the event to holders of
Rights under Section 11.1.2 and Section 13, and (ii) all references in this
Section 24 to Preferred Shares shall be deemed thereafter to refer to Common
Shares and/or, if appropriate, other securities.

               Notwithstanding anything in this Agreement to the contrary, prior
to the Distribution Date a filing by the Company with the Securities and
Exchange Commission shall constitute sufficient notice to the holders of
securities of the Company, including the Rights, for purposes of this Agreement
and no other notice need be given.

               Section 25. Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed (until another address is filed in
writing with the Rights Agent) as follows:

                      Advanced Medical Optics, Inc.
                      2525 Dupont Drive
                      Irvine, California  92612
                      Attention:  Secretary

Subject to the provisions of Section 21 and Section 24, any notice or demand
authorized by this Agreement to be given or made by the Company or by the holder
of any Right Certificate to or on the Rights Agent shall be sufficiently given
or made if sent by first-class mail, postage prepaid, addressed (until another
address is filed in writing with the Company) as follows:

                      -----------------------
                      -----------------------
                      -----------------------
                      Attention:
                                -------------

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Right Certificate (or, prior to
the Distribution Date, to the holder of any certificate representing Common
Shares) shall be sufficiently given or made if sent by first-class mail, postage
prepaid, addressed to such holder at the address of such holder as shown on the
registry books of the Company.

               Section 26. Supplements and Amendments. For so long as the Rights
are then redeemable, the Company may in its sole and absolute discretion, and
the Rights Agent shall, if the Company so directs, supplement or amend any
provision of this Agreement in any respect without the approval of any holders
of Rights or Common Shares. From and after the time that



                                       32
<PAGE>
the Rights are no longer redeemable, the Company may, and the Rights Agent
shall, if the Company so directs, from time to time supplement or amend this
Agreement without the approval of any holders of Rights (i) to cure any
ambiguity or to correct or supplement any provision contained herein which may
be defective or inconsistent with any other provisions herein or (ii) to make
any other changes or provisions in regard to matters or questions arising
hereunder which the Company may deem necessary or desirable, including but not
limited to extending the Final Expiration Date; PROVIDED, HOWEVER, that no such
supplement or amendment shall adversely affect the interests of the holders of
Rights as such (other than an Acquiring Person or an Affiliate or Associate of
an Acquiring Person), and no such supplement or amendment may cause the Rights
again to become redeemable or cause this Agreement again to become amendable
other than in accordance with this sentence; PROVIDED FURTHER, that the right of
the Board of Directors to extend the Distribution Date shall not require any
amendment or supplement hereunder. Upon the 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 26, the Rights Agent
shall execute such supplement or amendment. Without limiting the foregoing, at
any time prior to such time as any Person becomes an Acquiring Person, the
Company and the Rights Agent may amend this Agreement to lower the thresholds
set forth in Sections 1.1 and 3.1 to not less than the greater of (i) any
percentage greater than the largest percentage of the outstanding Common Shares
then known by the Company to be beneficially owned by any Person (other than an
Exempt Person) and (ii) 10%.

               Section 27. Exchange.

               27.1 Exchange of Common Shares for Rights. The Board of Directors
of the Company may, at its option, at any time after the occurrence of a Trigger
Event, exchange Common Shares for all or part of the then outstanding and
exercisable Rights (which shall not include Rights that have become void
pursuant to the provisions of Section 11.1.2) by exchanging at an exchange ratio
of one Common Share per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(such amount per Right being hereinafter referred to as the "Exchange
Consideration"). Notwithstanding the foregoing, the Board of Directors shall not
be empowered to effect such exchange at any time after any Acquiring Person
shall have become the Beneficial Owner of 50% or more of the Common Shares then
outstanding. From and after the occurrence of an event specified in Section
13.1, any Rights that theretofore have not been exchanged pursuant to this
Section 27.1 shall thereafter be exercisable only in accordance with Section 13
and may not be exchanged pursuant to this Section 27.1. The exchange of the
Rights by the Board of Directors may be made effective at such time, on such
basis and with such conditions as the Board of Directors in its sole discretion
may establish.

               27.2 Exchange Procedures. Immediately upon the action of the
Board of Directors of the Company ordering the exchange for any Rights pursuant
to Section 27.1 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 the Exchange Consideration. The
Company shall promptly give public notice of any such exchange; PROVIDED,
HOWEVER, that the failure to give, or any defect in, such notice shall not
affect the 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.



                                       33
<PAGE>
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
shall 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 the Rights that have become void pursuant to
the provisions of Section 11.1.2) held by each holder of Rights.

               27.3 Insufficient Shares. The Company may at its option
substitute, and, in the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit an exchange of
Rights for Common Shares as contemplated in accordance with this Section 27, the
Company shall substitute to the extent of such insufficiency, for each Common
Share that would otherwise be issuable upon exchange of a Right, a number of
Preferred Shares or fraction thereof (or equivalent preferred stock, as such
term is defined in Section 11.2) such that the current per share market price
(determined pursuant to Section 11.4) of one Preferred Share (or equivalent
preferred share) multiplied by such number or fraction is equal to the current
per share market price of one Common Share (determined pursuant to Section 11.4)
as of the date of such exchange.

               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 or corporation 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. Determination and Actions by the Board of Directors.
The Board of Directors of the Company shall have the exclusive power and
authority to administer this Agreement and to exercise the rights and powers
specifically granted to the Board of Directors of the Company or to the Company,
or as may be necessary or advisable in the administration of this Agreement,
including, without limitation, the right and power to (i) interpret the
provisions of this Agreement and (ii) make all determinations deemed necessary
or advisable for the administration of this Agreement (including, without
limitation, a determination to redeem or not redeem the Rights or amend this
Agreement). All such actions, calculations, interpretations and determinations
(including, for purposes of clause (y) below, all omissions with respect to the
foregoing) that are done or made by the Board of Directors of the Company in
good faith shall (x) be final, conclusive and binding on the Company, the Rights
Agent, the holders of the Rights, as such, and all other parties, and (y) not
subject the Board of Directors to any liability to the holders of the Rights.

               Section 31. 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



                                       34

Agreement shall remain in full force and effect and shall in no way be affected,
impaired or invalidated.

               Section 32. 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 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.

               Section 33. 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.

several Sections of this Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

                           CERTIFICATE OF DESIGNATIONS

                                       of

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                          ADVANCED MEDICAL OPTICS, INC.

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

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

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

               RESOLVED, that pursuant to the authority granted to and vested in
the Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation of this Corporation, the Board of Directors hereby creates a
series of Preferred Stock, par value $.01 per share (the "Preferred Stock"), of
the Corporation and hereby states the designation and number of shares, and
fixes the relative rights, powers and preferences, and qualifications,
limitations and restrictions thereof as follows:

               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 ___________. 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 Corporation
convertible into Series A Preferred Stock.

               Section 2. Dividends and Distributions.

               (A) Subject to the prior and superior rights of the holders of
        any shares of any class or series of stock of this Corporation ranking
        prior and superior to the Series A Preferred Stock with respect to
        dividends, the holders of shares of Series A Preferred Stock, in
        preference to the holders of Common Stock, par value $.01 per share (the



                                      A-1
<PAGE>
        "Common Stock"), of the Corporation, and of any other stock ranking
        junior to the Series A Preferred 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) $1.00 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 Corporation shall at
        any time declare or pay any dividend on the Common Stock payable in
        shares of Common Stock, or effect a subdivision, 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 Corporation shall declare a dividend or distribution on
        the Series A Preferred Stock as provided in paragraph (A) of this
        Section 2 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 $1.00 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 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



                                      A-2
<PAGE>
        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 Corporation. In the event the Corporation shall at
        any time declare or pay any dividend on the Common Stock payable in
        shares of Common Stock, or effect a subdivision, 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
        Corporation having general voting rights shall vote together as one
        class on all matters submitted to a vote of stockholders of the
        Corporation.

               (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
        Corporation 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 Corporation may at
               any time redeem, purchase or otherwise acquire shares of any such
               junior stock in exchange for shares of any stock of the
               Corporation ranking junior (both as to dividends and 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 Corporation shall not permit any subsidiary of the
        Corporation to purchase or otherwise acquire for consideration any
        shares of stock of the Corporation unless the Corporation 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 Corporation in any manner
whatsoever shall be retired and canceled 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.

               (A) Upon any liquidation, dissolution or winding up of the
        Corporation, voluntary or otherwise 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 an amount per share (the "Series A Liquidation
        Preference") equal to $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



                                      A-4
<PAGE>
        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 liquidation, 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
        Corporation shall at any time declare or pay any dividend on the Common
        Stock payable in shares of Common Stock, or effect a subdivision,
        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 are outstanding immediately prior to such
        event.

               (B) In the event, however, that there are not sufficient assets
        available to permit payment in full of the Series A Liquidation
        Preference and the liquidation preferences of all other classes and
        series of stock of the Corporation, if any, that rank on a parity with
        the Series A Preferred Stock in respect thereof, then the assets
        available for such distribution shall be distributed ratably to the
        holders of the Series A Preferred Stock and the holders of such parity
        shares in proportion to their respective liquidation preferences.

               (C) Neither the merger or consolidation of the Corporation into
        or with another corporation nor the merger or consolidation of any other
        corporation into or with the Corporation shall be deemed to be a
        liquidation, dissolution or winding up of the Corporation within the
        meaning of this Section 6.

               Section 7. Consolidation, Merger, etc. In case the Corporation
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 Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision,
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



                                      A-5
<PAGE>
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 by the Company.

               Section 9. Rank. The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up, junior to all series of any other class
of the Corporation's Preferred Stock, except to the extent that any such other
series specifically provides that it shall rank on a parity with or junior to
the Series A Preferred Stock.

               Section 10. Amendment. At any time any shares of Series A
Preferred Stock are outstanding, the Certificate of Incorporation of the
Corporation 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
separately as a single class.

               Section 11. Fractional Shares. Series A Preferred Stock may be
issued in fractions of a share that shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Stock.

               IN WITNESS WHEREOF, this Certificate of Designations is executed
on behalf of the Corporation by its Chairman of the Board this ___ day of
__________, 2002.

be issuable on the exercise hereof, nor shall anything contained in the
Agreement or herein be construed to confer upon the holder hereof, 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

otherwise, until the Right or Rights evidenced by this Right Certificate shall

restrictions of the Agreement shall remain in full force and effect and shall in

           As described in the Rights Agreement, Rights which are held
            by or have been held by an Acquiring Person or Associates
         or Affiliates thereof (as defined in the Rights Agreement) and
    certain transferees thereof shall become null and void and will no longer
                                be transferable.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

               On ___________, 2002 the Board of Directors of Advanced Medical
Optics, Inc. (the "Company") declared a dividend of one preferred share purchase
right (a "Right") for each share of common stock, $.01 par value (the "Common
Shares"), of the Company outstanding at the close of business on
_______________, 2002 (the "Record Date"). As long as the Rights are attached to
the Common Shares, the Company will issue one Right (subject to adjustment) with
each new Common Share so that all such shares will have attached Rights. When
exercisable, each Right will entitle the registered holder to purchase from the
Company one one-hundredth of a share of Series A Junior Participating Preferred
Stock (the "Preferred Shares") at a price of $_________ per one one-hundredth of
a Preferred Share, subject to adjustment (the "Purchase Price"). The description
and terms of the Rights are set forth in a Rights Agreement, dated as of
___________, 2002, as the same may be amended from time to time (the
"Agreement"), between the Company and ______________, as Rights Agent (the
"Rights Agent").

               Until the earlier to occur of (i) ten (10) days following a
public announcement that a person or group of affiliated or associated persons
has acquired, or obtained the right to acquire, beneficial ownership of ____% or
more of the Common Shares (an "Acquiring Person") or (ii) ten (10) business days
(or such later date as may be determined by action of the Board of Directors
prior to such time as any person or group of affiliated persons becomes an
Acquiring Person) following the commencement or announcement of an intention to
make a tender offer or exchange offer the consummation of which would result in
the beneficial ownership by a person or group of ____% or more of the Common
Shares (the earlier of (i) and (ii) being called the "Distribution Date"), the
Rights will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate together
with a copy of this Summary of Rights.

               The Agreement provides that until the Distribution Date (or
earlier redemption exchange, termination, or expiration of the Rights), the
Rights will be transferred with and only with the Common Shares. Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the close of business on the Record Date
upon transfer or new issuance of the Common Shares will contain a notation
incorporating the Agreement by reference. Until the Distribution Date (or
earlier redemption, exchange, termination or expiration of the Rights), the
surrender for transfer of any certificates for Common Shares, with or without
such notation or a copy of this Summary of Rights, will also constitute the
transfer of the Rights associated with the Common Shares represented by such
certificate. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common



                                      C-1
<PAGE>
Shares as of the close of business on the Distribution Date and such separate
Right Certificates alone will evidence the Rights.

               The Rights are not exercisable until the Distribution Date. The
Rights will expire on ___________, 2012, subject to the Company's right to
extend such date (the "Final Expiration Date"), unless earlier redeemed or
exchanged by the Company or terminated.

               Each Preferred Share purchasable upon exercise of the Rights will
be entitled, when, as and if declared, to a minimum preferential quarterly
dividend payment of $1.00 per share but will be entitled to an aggregate
dividend of 100 times the dividend, if any, declared per Common Share. In the
event of liquidation, dissolution or winding up of the Company, the holders of
the Preferred Shares will be entitled to a minimum preferential liquidation
payment of $100 per share (plus any accrued but unpaid dividends) but will be
entitled to an aggregate payment of 100 times the payment made per Common Share.
Each Preferred Share will have 100 votes and will vote together with the Common
Shares. Finally, in the event of any merger, consolidation or other transaction
in which Common Shares are exchanged, each Preferred Share will be entitled to
receive 100 times the amount received per Common Share. Preferred Shares will
not be redeemable. These rights are protected by customary antidilution
provisions. Because of the nature of the Preferred Share's dividend, liquidation
and voting rights, the value of one one-hundredth of a Preferred Share
purchasable upon exercise of each Right should approximate the value of one
Common Share.

               The Purchase Price payable, and the number of Preferred Shares or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or warrants to subscribe for or purchase Preferred Shares or convertible
securities at less than the current market price of the Preferred Shares or
(iii) upon the distribution to holders of the Preferred Shares of evidences of
indebtedness, cash, securities or assets (excluding regular periodic cash
dividends at a rate not in excess of 125% of the rate of the last regular
periodic cash dividend theretofore paid or, in case regular periodic cash
dividends have not theretofore been paid, at a rate not in excess of 50% of the
average net income per share of the Company for the four quarters ended
immediately prior to the payment of such dividend, or dividends payable in
Preferred Shares (which dividends will be subject to the adjustment described in
clause (i) above)) or of subscription rights or warrants (other than those
referred to above).

               In the event that a Person becomes an Acquiring Person or if the
Company were the surviving corporation in a merger with an Acquiring Person or
any affiliate or associate of an Acquiring Person and the Common Shares were not
changed or exchanged, each holder of a Right, other than Rights that are or were
acquired or beneficially owned by the Acquiring Person (which Rights will
thereafter be void), will thereafter have the right to receive upon exercise
that number of Common Shares having a market value of two times the then current
Purchase Price of the Right. In the event that, after a person has become an
Acquiring Person, the Company were acquired in a merger or other business
combination transaction or more than 50% of its assets or earning power were
sold, proper provision shall be made so that each holder of a Right shall
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase


                                      C-2
<PAGE>
Price of the Right, that number of shares of common stock of the acquiring
company which at the time of such transaction would have a market value of two
times the then current Purchase Price of the Right.

               At any time after a Person becomes an Acquiring Person and prior
to the earlier of one of the events described in the last sentence of the
previous paragraph or the acquisition by such Acquiring Person of 50% or more of
the outstanding Common Shares, the Board of Directors may cause the Company to
exchange the Rights (other than Rights owned by an Acquiring Person which will
have become void), in whole or in part, for Common Shares at an exchange rate of
one Common Share per Right (subject to adjustment).

               No adjustment in the Purchase Price will be required until
cumulative adjustments require an adjustment of at least 1% in such Purchase
Price. No fractional Preferred Shares or Common Shares will be issued (other
than fractions of Preferred Shares which are integral multiples of one
one-hundredth of a Preferred Share, which may, at the election of the Company,
be evidenced by depository receipts), and in lieu thereof, a payment in cash
will be made based on the market price of the Preferred Shares or Common Shares
on the last trading date prior to the date of exercise.

               The Rights may be redeemed in whole, but not in part, at a price
of $.01 per Right (the "Redemption Price") by the Board of Directors at any time
prior to the time that an Acquiring Person has become such. The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

               Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Company beyond those as an existing
stockholder, including, without limitation, the right to vote or to receive
dividends.

               Any of the provisions of the Agreement may be amended by the
Board of Directors of the Company for so long as the Rights are then redeemable,
and after the Rights are no longer redeemable, the Company may amend or
supplement the Agreement in any manner that does not adversely affect the
interests of the holders of the Rights (other than an Acquiring Person or an
affiliate or associate of an Acquiring Person). The Company may at any time
prior to such time as any person becomes an Acquiring Person amend the Agreement
to lower the thresholds described above to no less than the greater of (i) any
percentage greater than the largest percentage of the outstanding Common Shares
then known by the Company to be beneficially owned by any person or group of
affiliated or associated persons (other than an Exempt Person) and (ii) 10%.

               A copy of the Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to the Company's Form 10. A copy of the
Agreement is available free of charge from the Company. This summary description
of the Rights does not purport to be complete and is qualified in its entirety
by reference to the Agreement, which is incorporated herein by reference.
