        This Rights Agreement (the "Agreement") is made and entered into as of
March 8, 2002, by and between I-Flow Corporation, a Delaware corporation (the
"Company"), and American Stock Transfer & Trust Company, a New York corporation,
as rights agent (the "Rights Agent").

        WHEREAS, the Board of Directors of the Company has authorized and
declared a dividend of one preferred stock purchase right (a "Right") for each
Common Share (as hereinafter defined) of the Company outstanding on March 15,
2002 (the "Record Date"), each Right representing the right to purchase one
one-hundredth of a Preferred Share (as hereinafter defined), upon the terms and
subject to the conditions set forth herein, and has further authorized and
directed the issuance of one Right with respect to each Common Share that shall
become outstanding between the Record Date and the earliest of the Distribution
Date, the Redemption Date or the Expiration Date (as such terms are hereinafter
defined).

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

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

        (a) "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 promulgated under the Exchange Act, as in
effect on the date hereof.

        (b) A Person shall be deemed the "Beneficial Owner" of and shall be
deemed to "Beneficially Own" any securities:

               (i) that such Person or any of such Person's Affiliates or
        Associates beneficially owns, directly or indirectly, for purposes of
        Section 13(d) of the Exchange Act and Rule 13d-3 promulgated under the
        Exchange Act, in each case as in effect on the date hereof;

               (ii) that such Person or any of such Person's Affiliates or

        regulatory requirements, the fulfillment of a condition or otherwise)
        pursuant to any agreement, arrangement or understanding, or upon the
        exercise of conversion rights, exchange rights, rights (other than these
        Rights), warrants or options, or otherwise, provided, however, that a
        Person shall not be deemed the Beneficial Owner of, or to Beneficially
        Own, securities tendered pursuant to a tender offer 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;

               (iii) that such Person or any such Person's Affiliates or

        others, pursuant to any agreement, arrangement or understanding,
        provided, however, that a Person shall not be deemed the Beneficial
        Owner of, or to Beneficially Own, any security if the agreement,
        arrangement or understanding to vote such security (A) arises solely
        from a revocable proxy given to such Person or any of such Person's
        Affiliates or Associates in response to a public proxy solicitation made
        pursuant to and in accordance with the applicable rules and regulations
        promulgated under the Exchange Act, and (B) is not also then reportable

on the date in question (or, if no Closing Price is available on the date in
question, on the Trading Day immediately preceding the date in question), then
each such non-comparable Closing Price so used shall be appropriately adjusted
by the Board of Directors in order to make the Closing Price on each Trading Day
during the period used for the determination of the Current Market Price fully

has become a 15% Stockholder.

        (p) "15% Stockholder" shall mean any Person that Beneficially Owns 15%
or more of the Voting Shares of the Company then outstanding; provided, however,
that the term "15% Stockholder" shall not include: (i) an Exempt Person; (ii)
any Person that would not otherwise be a 15% Stockholder but for a reduction in
the number of outstanding Voting Shares resulting from a stock repurchase
program or other similar plan of the Company or from a self tender offer of the
Company, which plan or tender offer commenced on or after the date hereof;
provided, however, that the term "15% Stockholder" shall include such Person

and Associates of such Person, shall Beneficially Own 15% or more of the Voting
Shares of the Company then outstanding; or (v) any Person (a "Transferee") that
acquires Voting Shares from a Person described in clause (iv) above that has not

the Company then outstanding. In calculating the percentage of the outstanding

deemed outstanding, and Voting Shares that are not Beneficially Owned by such
Person and that are subject to issuance upon the exercise or conversion of
outstanding conversion rights, exchange rights, rights, warrants or options
shall not be deemed outstanding. Any determination made by the Board of
Directors of the Company as to whether any Person is or is not a 15% Stockholder
shall be conclusive and binding upon all holders of Rights.

Section 11(a)(ii) Event, the Board of Directors of the Company may determine
that a Person who may otherwise be a 15% Stockholder pursuant to the foregoing
provisions of this definition, shall not be so deemed for purposes of this
Agreement, and no 15% Ownership Date shall be deemed to have occurred, under the
following circumstances: (i) such Person has become such inadvertently or (ii)
such Person has become such solely as the result of any agreement, arrangement
or understanding among two or more stockholders of the Company, none of whom is
individually the Beneficial Owner of 15% or more of the Company's stock other
than by reason of paragraph (iv) of the definition of the term Beneficial
Ownership herein and (iii) such Person ceases to be a 15% Stockholder or enters
into such agreement or arrangement as the Board of Directors of the Company may
approve or the Board of Directors is otherwise satisfied that such determination
is in the best interests of the Company and its stockholders.

               March 8, 2002 by and between I-Flow Corporation and American
               Stock Transfer & Trust Company, as Rights Agent, as amended to

               is on file at the principal executive offices of I-Flow
               Corporation. Under certain circumstances specified in the Rights
               Agreement, such Rights will be represented by separate
               certificates and will no longer be represented by this
               certificate. In addition, under certain circumstances specified
               in the Rights Agreement, Rights beneficially owned by certain
               Persons may become null and void. I-Flow Corporation will mail to
               the record holder of this certificate a copy of the Rights
               Agreement without charge promptly following its receipt of a
               written request therefor.

        (e) Certificates for Common Shares issued at any time on or after the
Distribution Date and prior to the earlier of the Redemption Date or the Rights

               between I-Flow Corporation and American Stock Transfer & Trust
               Company, as Rights Agent.

        (f) In the event that at any time on or after the earlier of the date of
the first Section 11(a)(ii) Event or the date of the first Section 13(a) Event

the Company shall issue any Common Shares pursuant to the exercise of conversion
rights, exchange rights, rights (other than Rights), warrants or options that

Section 11(a)(ii) Event or the date of the first Section 13(a) Event, then,
unless the Board of Directors of the Company shall have provided otherwise at
the time of the issuance or grant of such conversion rights, exchange rights,
rights (other than Rights), warrants or options, the Rights Agent shall, as soon
as practicable after the date of such event, send by first-class,

<PAGE>

        (g) Notwithstanding the foregoing provisions of this Section 3, the
Rights Agent shall not send any Right Certificate to any 15% Stockholder or any
of its Affiliates or Associates or to any Person if the Rights held by such
Person are Beneficially Owned by a 15% Stockholder or any of its Affiliates or
Associates. Any determination made by the Board of Directors of the Company as
to whether any Common Shares are or were Beneficially Owned at any time by a 15%
Stockholder or an Affiliate or Associate of a 15% Stockholder shall be
conclusive and binding upon all holders of Rights.

        Section 4. Form of Right Certificates. The Right Certificates and the
form of assignment, including certificate, and the form of election to purchase,
including certificate, printed on the reverse thereof, when, as and if issued,
shall be substantially the same as Exhibit A 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 upon which the Rights or the securities
of the Company issuable upon exercise of the Rights may from time to time be
listed, or to conform to usage. Subject to Section 22 hereof, Right
Certificates, whenever issued, that are issued in respect of Common Shares that
were issued and outstanding as of the Close of Business on the Distribution
Date, shall be dated as of the Distribution Date.

        Section 5. Countersignature and Registration.

        (a) The Right Certificates shall be executed on behalf of the Company by
any of its Chairman of the Board, its Chief Executive Officer, its President or
any Vice President, either manually or by facsimile signature, and may have
affixed thereto the Company's seal or a facsimile thereof attested by its
Secretary or any Assistant Secretary, either manually or by facsimile signature.
The Right Certificates shall be manually countersigned by the Rights Agent and
shall not be valid for any purpose unless so countersigned. In case any officer
of the Company who shall have signed any of the Right Certificates ceases to be
an officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right Certificates may nevertheless
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 an officer of the Company. Any Right
Certificate may be signed on behalf of the Company by any person who at the
actual date of such execution is a proper officer of the Company to sign such
Right Certificate, even though such person was not such an officer at the date
of the execution of this Agreement.

        (b) In case any authorized signatory of the Rights Agent who shall have
countersigned any of the Right Certificates ceases to be such signatory before
delivery by the Company, such Right Certificates, nevertheless, may be issued
and delivered by the Company with the same force and effect as though the person
who countersigned such Right Certificates had not ceased to be an authorized
signatory; and any Right Certificate may be countersigned on behalf of the
Rights Agent by any person who, at the actual date of the countersignature of
such Right Certificate, was a proper signatory of the Rights Agent to
countersign such Right Certificate, although at the date of the execution of
this Rights Agreement any such person was not such a signatory.

        (c) Following the Distribution Date, the Rights Agent shall keep or
cause to be kept at its principal offices books for registration and transfer of
the Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of Right Certificates, the number of Rights
represented on its face by each Right Certificate and the date of each Right
Certificate.

        Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.

        (a) Subject to the provisions of Sections 6(c), 7(d) and 14 hereof, at
any time after the Close of Business on the Distribution Date, and so long as
any Rights represented thereby remain outstanding, any one or more Right
Certificates may be transferred, split-up, combined or exchanged for one or more
Right Certificates representing the same aggregate number of Rights as the Right
Certificates surrendered. Any registered holder desiring to transfer, split up,
combine or exchange one or more Right Certificates shall deliver such request in
writing to the Rights Agent, and shall surrender the Right Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
with the form of assignment, including certificate, on the reverse side thereof
completed and duly executed, with signature guaranteed. Thereupon, the Rights
Agent shall countersign and deliver to the Person entitled thereto one or more
Right Certificates, as so requested. The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Right
Certificates.

        (b) 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
such Right Certificate if mutilated, the Company shall issue and deliver to the
Rights Agent for delivery to the record holder of such Right Certificate a new
Right Certificate of like tenor in lieu of such lost, stolen, destroyed or
mutilated Right Certificate.

        (c) Notwithstanding anything to the contrary in this Section 6, the
Rights Agent shall not countersign and deliver a Right Certificate to any Person
if such Right Certificate represents, or would represent when held by such
Person, Rights that had become or would become null and void pursuant to Section
7(d) hereof.

        Section 7. Exercise of Rights.

        (a) Until the Distribution Date, no Right may be exercised.

        (b) Subject to Section 7(d) and (g) hereof and the other provisions of
this Agreement, at any time after the Close of Business on the Distribution Date
and prior to the Close of Business on the earlier of the Redemption Date or the
Rights Expiration Date, the registered holder of any Right Certificate may
exercise the Rights represented thereby in whole or in part upon surrender of
such Right Certificate, with the form of election to purchase, including
certificate, on the reverse side thereof completed and duly executed, with
signature guaranteed, to the Rights Agent at the office of the Rights Agent at
American Stock Transfer & Trust Company, 59 Maiden Lane, New York, NY 10038,
Attn: Corporate Trust Department, together with payment of the Exercise Price
for each Right exercised. Upon the exercise of an exercisable Right and payment
of the Exercise Price in accordance with the provisions of this Agreement, the
holder of such Right shall be entitled to receive, subject to adjustment as
provided herein, one one-hundredth of a Preferred Share (or Common Shares, other
securities, cash and/or other property in accordance with the provisions of this
Agreement).

        (c) The "Exercise Price" for the exercise of each Right shall initially
be $30.00 and shall be payable in lawful money of the United States of America
in accordance with Section 7(f) hereof. The Exercise Price and the number of
Preferred Shares (or Common Shares, other securities, cash and/or other
property) to be acquired upon exercise of a Right shall be subject to adjustment
from time to time as provided in Sections 7(e), 11 and 13 hereof and the other
provisions of this Agreement.

                                       8
<PAGE>

        (d) Notwithstanding anything in this Agreement to the contrary, from and
after the earlier of the date of the first Section 11(a)(ii) Event and the date
of the first Section 13(a) Event, any Rights that are or were Beneficially Owned
by a 15% Stockholder or any Affiliate or Associate of a 15% Stockholder at any
time on or after the Distribution Date shall be null and void, and for all
purposes of this Agreement such Rights shall thereafter be deemed not to be
outstanding, and any holder of such Rights (whether or not such holder is a 15%
Stockholder or an Affiliate or Associate of a 15% Stockholder) shall thereafter
have no right to exercise or exchange such Rights.

        (e) Prior to the Distribution Date, if the Board of Directors of the
Company shall have determined that such action adequately protects the interests
of the holders of Rights, the Company may, in its discretion, substitute for all
or any portion of the Preferred Shares that would otherwise be issuable (after
the Close of Business on the Distribution Date) upon the exercise of each Right
and payment of the Exercise Price (i) cash, (ii) other equity securities of the
Company, (iii) debt securities of the Company, (iv) other property or (v) any
combination of the foregoing, in each case having an aggregate Current Market
Price equal to the aggregate Current Market Price of the Preferred Shares for
which substitution is made. Subject to Section 7(d) hereof, in the event that
the Company takes any action pursuant to this Section 7(e), such action shall
apply uniformly to all outstanding Rights.

        (f) Upon receipt of a Right Certificate representing exercisable Rights,
with the form of election to purchase, including certificate, properly completed
and duly executed, with signature guaranteed, accompanied by payment of the
Exercise Price for each Right to be exercised 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 hereof by certified check or cashier's
check payable to the order of the Company, the Rights Agent shall thereupon
promptly (i) requisition from the transfer agent of the Preferred Shares (or
Common Shares and/or other securities in accordance with this Agreement)
certificates for the number of Preferred Shares (or such other securities) to be
purchased, and the Company hereby irrevocably authorizes such transfer agent to
comply with all such requests, and/or, as provided in Section 14 hereof,
requisition from the depositary agent described therein depositary receipts
representing such number of one-hundredths of a Preferred Share (or such other
securities) as are to be purchased (in which case certificates for the Preferred
Shares (or such other securities) represented by such receipts shall be
deposited by the transfer agent with such depositary agent) and the Company
hereby directs such depositary agent to comply with such request, (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of issuance of fractional Preferred Shares (or such other securities) in
accordance with Section 14 hereof or such other cash or property to be issued
upon exercise of the Rights in accordance with the provisions of this Agreement,
(iii) after receipt of such certificates, depositary receipts or cash, 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 thereof, deliver such cash to or
upon the order of the registered holder of such Right Certificate.

        (g) Notwithstanding the foregoing provisions of this Section 7, the
exercisability of the Rights shall be suspended for such period as shall
reasonably be necessary for the Company to register and qualify the Preferred
Shares and/or Common Shares or other securities to be issued pursuant to the
exercise of the Rights under the Securities Act and any applicable securities
law of any jurisdiction; provided, however, that nothing contained in this
Section 7 shall relieve the Company of its obligations under Section 9(c)
hereof.

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

                                       9
<PAGE>

        (i) Notwithstanding anything in this Agreement to the contrary, neither
the Rights Agent nor the Company shall be obligated to undertake any action
whatsoever 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 Rights 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 or the Rights Agent shall request.

        (j) Neither the Company nor the Rights Agent shall have any liability to
any holder of Rights or any other Person as a result of the Company's failure to
make any determination under this Section 7 or any other section with respect to
a 15% Stockholder or an Affiliate or Associate of a 15% Stockholder.

        Section 8. Cancellation and Destruction of Right Certificates. All Right
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, (i) if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in canceled
form or (ii) if surrendered to the Rights Agent, be canceled by the Rights
Agent, and no Right Certificates shall be issued in lieu thereof except as
expressly permitted by this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement, and the Rights Agent shall promptly
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.

        Section 9. Reservation and Availability of Capital Stock.

        (a) Subject to Sections 7(e) and 9(f) hereof, the Company shall cause to
be reserved and kept available out of its authorized and unissued equity
securities (or out of its authorized and issued equity securities held in its
treasury), the number of such equity securities that will from time to time be
sufficient to permit the exercise in full of all outstanding Rights.

        (b) In the event that any securities issuable upon exercise of the
Rights are listed on any national securities exchange, the Company shall use its
best efforts, from and after such time as the Rights become exercisable, to
cause all such securities issued or reserved for such issuance to be listed on
such exchange upon official notice of issuance upon such exercise.

        (c) If necessary to permit the issuance of securities upon exercise of
the Rights, the Company shall use its best efforts, from and after the
Distribution Date, to register and qualify such securities under the Securities
Act, the Exchange Act and any other applicable securities laws and to keep such
registration effective so long as required under such laws.

        (d) The Company shall take all such action as may be necessary to ensure
that all securities delivered upon exercise of the Rights shall, at the time of
delivery of the certificates for such securities (subject to payment of the
Exercise Price), be duly and validly authorized and issued and fully paid and
nonassessable securities.

        (e) The Company shall pay when due and payable any and all federal
and state transfer taxes and charges that may be payable in respect of the
issuance or delivery of the Right Certificates or of any securities upon the
exercise of Rights. The Company shall not, however, be required to pay any
transfer tax that may be payable in respect of any transfer or delivery of a
Right Certificate to a Person other than,

                                       10
<PAGE>

or the issuance or delivery of a certificate for securities in respect of a name
other than that of, the registered holder of the Right Certificate representing
Rights surrendered for exercise, or to issue or deliver any certificate for
securities upon the exercise of any Right until any such tax shall have been
paid (any such tax being payable by the 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.

        (f) With respect to the Common Shares and/or other securities issuable
pursuant to Section 11(a)(ii) and (iii) hereof, the foregoing covenants of this
Section 9 shall be applicable only upon and following the occurrence of a
Section 11(a)(ii) Event.

        Section 10. Securities Record Date. Each Person in whose name any
certificate for securities of the Company is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of the
securities represented thereby on, and such certificate shall be dated, the date
upon which the Right Certificate representing such Rights was duly surrendered
and payment of the Exercise Price (and any applicable taxes) was made; provided,
however, that if the date of such surrender and payment is a date upon which the
securities transfer books of the Company are closed, such Person shall be deemed
to have become the record holder of such securities on, and such certificate
shall be dated, the next succeeding Business Day on which the securities
transfer books of the Company are open.

        Section 11. Adjustment of Exercise Price, Number of Shares Issuable Upon
Exercise of Rights or Number of Rights. The Exercise Price, the number and kind
of securities that may be purchased upon exercise of a Right and the number of
Rights outstanding are subject to adjustment from time to time as provided in
this Section 11.

               (a)(i) In the event that the Company shall at any time after the
        Close of Business on the Record Date and prior to the Close of Business
        on the earlier of the Redemption Date or the Rights Expiration Date (A)
        declare or pay any dividend on the Preferred Shares payable in Preferred
        Shares or Voting Shares, (B) subdivide the outstanding Preferred Shares,
        (C) combine the outstanding Preferred Shares into a smaller number of
        Preferred Shares or (D) issue Preferred Shares or other securities of
        the Company (other than those issuances for which an adjustment is
        required under Section 11(b) hereof) 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) or in a reorganization of the Company, then, and
        upon each such event, the number and kind of Preferred Shares or other
        securities issuable upon the exercise of a Right on the date of such
        event shall be proportionately adjusted so that the holder of any Right
        exercised on or after such date shall be entitled to receive, upon the
        exercise thereof and payment of the Exercise Price, the aggregate number
        and kind of Preferred Shares or other securities or other property, as
        the case may be, that, if such Right had been exercised immediately
        prior to such date and at a time when such Right was exercisable and the
        transfer books of the Company were open, such holder would have owned
        upon such exercise and would have been entitled to receive by virtue of
        such dividend, subdivision, combination or reclassification. If an event
        occurs that would require an adjustment under both this Section 11(a)(i)
        and Section 11(a)(ii) hereof, the adjustment provided for in this
        Section 11(a)(i) shall be in addition to, and shall be made prior to,
        any adjustment required pursuant to Section 11(a)(ii) hereof.

               (ii) In the event that a 15% Ownership Date shall have occurred
        and neither the Redemption Date nor the Expiration Date shall have
        occurred prior to the tenth Business Day following such 15% Ownership
        Date (a "Section 11(a)(ii) Event"), then, and upon each such Section
        11(a)(ii) Event, proper provision shall be made so that, except as
        provided in Section 7(d) hereof, each holder of a Right shall thereafter
        have the right to receive, upon the exercise thereof

                                       11
<PAGE>

        in accordance with the terms of this Agreement and payment of the then
        current Exercise Price, such number of Common Shares of the Company as
        shall equal the result obtained by (A) multiplying the then current
        Exercise Price by the then number of one-hundredths of a Preferred Share
        for which a Right was exercisable immediately prior to such Section
        11(a)(ii) Event (or, if the Distribution Date shall not have occurred
        prior to the date of such Section 11(a)(ii) Event, the number of
        one-hundredths of a Preferred Share for which a Right would have been
        exercisable if the Distribution Date had occurred on the Business Day
        immediately preceding the date of such Section 11(a)(ii) Event), and (B)
        dividing that product by 50% of the Current Market Price of a Common
        Share on the date of occurrence of the relevant Section 11(a)(ii) Event
        (such number of shares being hereinafter referred to as the "Adjustment
        Shares"). Successive adjustments shall be made pursuant to this
        paragraph each time a Section 11(a)(ii) Event occurs.

               (iii) In the event that on the date of a Section 11(a)(ii) Event
        the aggregate number of Common Shares that are authorized by the
        Company's Certificate of Incorporation, as amended from time to time,
        but not outstanding or reserved for issuance for purposes other than
        upon exercise of the Rights is less than the aggregate number of
        Adjustment Shares thereafter issuable upon the exercise in full of the
        Rights in accordance with Section 11(a)(ii) hereof (the excess of such
        number of Adjustment Shares over and above such number of Common Shares
        being hereinafter referred to as the "Unavailable Adjustment Shares"),
        then, and upon each such event, the Company shall substitute for the pro
        rata portion of the Unavailable Adjustment Shares that would otherwise
        be issuable thereafter upon the exercise of each Right and payment of
        the Exercise Price (A) cash, (B) other equity securities of the Company
        (including, without limitation, shares of preferred stock of the Company
        or units of such shares having the same Current Market Price as one
        Common Share (a "Common Share Equivalent")), (C) debt securities of the
        Company, (D) other property or (E) any combination of the foregoing, in
        each case having an aggregate Current Market Price equal to the
        aggregate Current Market Price of the Unavailable Adjustment Shares for
        which substitution is made. Subject to Section 7(d) hereof, in the event
        that the Company takes any action pursuant to this Section 11(a)(iii),
        such action shall apply uniformly to all outstanding Rights.

        (b) In the event that the Company shall, at any time after the Close of
Business on the Record Date and prior to the Close of Business on the earlier of
the Redemption Date or the Rights Expiration Date, fix a record date for the
issuance of rights, options or warrants to all holders of Preferred Shares
entitling such holders initially to subscribe for or purchase Preferred Shares
(or shares having the same rights, privileges and preferences as the Preferred
Shares ("Preferred Share Equivalents")) or securities convertible into Preferred
Shares or Preferred Share Equivalents, at a price per Preferred Share or
Preferred Share Equivalent (or having a conversion price per share, if a
security convertible into Preferred Shares or Preferred Share Equivalents) less
than the Current Market Price per Preferred Share on such record date, then, and
upon each such event, the Exercise Price to be in effect after such record date
shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be equal
to the sum of the number of Preferred Shares outstanding on such record date
plus the number of Preferred Shares that the aggregate offering price of the
total number of Preferred Shares and/or Preferred Share Equivalents to be so
offered (and/or the aggregate initial conversion price of the convertible
securities to be so offered) would purchase at such Current Market Price, and
the denominator of which shall be equal to the number of Preferred Shares
outstanding on such record date plus the number of additional Preferred Shares
and/or Preferred Share Equivalents to be offered for subscription or purchase
(or into which the convertible securities to be so 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; and
provided further, that if such rights, options or warrants are not

                                       12
<PAGE>

exercisable immediately upon issuance but become exercisable only upon the
occurrence of a specified event or the passage of a specified period of time,
then the adjustment to the Exercise Price shall be made and become effective
only upon the occurrence of such event or such passage of time, and such
adjustment shall be made as if the record date for the issuance of such rights,
options or warrants had been the Business Day immediately preceding the date
upon which such rights, options or warrants became exercisable. Preferred Shares
owned by or held for the account of the Company shall not be deemed outstanding
for the purpose of any such computation. Such adjustment to the Exercise Price
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 Exercise Price shall
be adjusted to be the Exercise Price that would then be in effect if such record
date had not been fixed.

        (c) In the event that the Company shall, at any time after the Close of
Business on the Record Date and prior to the Close of Business on the earlier of
the Redemption Date or the Rights Expiration Date, 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 surviving corporation) of assets (other than a distribution for
which an adjustment is required under Section 11(a)(i) or (b) hereof or a
regular quarterly cash dividend), then the Exercise Price to be in effect after
such record date shall be determined by multiplying the Exercise Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be equal to the excess of the Current Market Price per Preferred Share on
such record date over and above the fair market value of the portion of the
securities or assets to be so distributed with respect to one Preferred Share,
and the denominator of which shall be equal to such Current Market Price per
Preferred Share; 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.
Such adjustments shall be made successively whenever such a record date is
fixed, and in the event that such a distribution is not so made, the Exercise
Price shall be adjusted to be the Exercise Price that would then be in effect if
such record date had not been fixed.

        (d) For the purpose of any computation under this Section 11, if the
Preferred Shares are not publicly held or traded, the "Current Market Price" per
Preferred Share shall be conclusively deemed to be the Current Market Price per
Common Share multiplied by 100.

        (e) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the then
current Exercise Price; provided, however, that any adjustments that by reason
of this Section 11(e) are not required to be made shall be cumulated 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-thousandth of a
Common Share or other share or one-millionth of a Preferred Share, as the case
may be.

        (f) If, as a result of an adjustment made pursuant to Section 11(a)
hereof, the holder of any Right shall be entitled to receive any securities of
the Company other than Preferred Shares upon exercise of such Right, and if an
event occurs in respect of such securities that, if it were to occur in respect
of Preferred Shares, would require an adjustment under this Section 11 in
respect of Preferred Shares, then the number of such other securities 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 Preferred Shares contained in this Section 11, and
the other provisions of this Agreement with respect to Preferred Shares shall
apply on like terms to any such other securities.

        (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Exercise Price hereunder shall represent the right to
purchase, at the adjusted Exercise Price, the number

                                       13
<PAGE>

of 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.

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

        (i) The Company may elect, on or after the date of any adjustment of the
Exercise Price, to adjust the number of Rights instead of making any adjustment
in the number of Preferred Shares purchasable upon the exercise of a Right. Each
of the Rights outstanding after such adjustment of the number of Rights shall be
exercisable for the number of one-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 one-thousandth of a Right) obtained by
dividing the Exercise Price in effect immediately prior to the adjustment of the
Exercise Price by the Exercise Price in effect immediately after such adjustment
of the Exercise Price. The Company shall make a public announcement of its
election to adjust the number of Rights pursuant to this Section 11(i),
indicating the record date for the adjustment and, if known at the time, the
amount of the adjustment to be made. Such record date may be the date on which
the Exercise Price is adjusted or any day thereafter, but, if separate Right
Certificates have been issued, it shall be at least 10 days after the date of
such public announcement. If separate Right Certificates have been issued, upon
each adjustment of the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Right Certificates on such record date Right Certificates
representing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment or, at the option of
the Company, 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 such adjustment, and upon surrender thereof if required by the Company,
new Right Certificates representing all the Rights to which such holders shall
be entitled after such adjustment. Right Certificates to be so distributed shall
be issued, executed and countersigned in the manner provided for herein (and may
bear, at the option of the Company, the adjusted Exercise 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.

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

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

                                       14
<PAGE>

        (l) In any case in which this Section 11 shall require that an
adjustment in the Exercise 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 the number of one-hundredths of a Preferred Share and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of one-hundredths of a Preferred Share and other capital stock or
securities of the Company, if any, issuable upon such exercise on the basis of
the Exercise Price in effect prior to such adjustment; provided, however, that
the Company shall deliver to such holder a due bill or other appropriate
instrument representing such holder's right to receive such additional shares
upon the occurrence of the event requiring such adjustment.

        (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such further adjustments in the number of
one-hundredths of a Preferred Share that may be purchased upon exercise of one
Right, and such further adjustments in the Exercise Price, in addition to those
adjustments expressly required by this Section 11, as and to the extent that the
Company in its sole discretion shall determine to be advisable in order that any
(i) consolidation or subdivision of the Preferred Shares, (ii) issuance wholly
for cash of any Preferred Shares at less than the Current Market Price thereof,
(iii) issuance wholly for cash of Preferred Shares or securities that by their
terms are convertible into or exchangeable for Preferred Shares, (iv) dividends
on Preferred Shares payable in Preferred Shares or (v) issuance of rights,
options or warrants referred to in Section 11(b) hereof, hereafter made by the
Company to holders of its Preferred Shares shall not be taxable to such
stockholders.

        (n) In the event that the Company shall, at any time after the Close of
Business on the Record Date and prior to the Close of Business on the earliest
of the date of the first Section 11(a)(ii) Event, the date of the first Section
13(a) Event, the Redemption Date or the Rights Expiration Date, (i) pay any
dividend on the Common Shares payable in Common Shares, (ii) subdivide the
outstanding Common Shares, (iii) combine the outstanding Common Shares into a
smaller number of Common Shares or (iv) issue Common Shares in a
reclassification of the Common Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), then, and upon each such event, the Exercise Price to
be in effect after such event shall be determined by multiplying the Exercise
Price in effect immediately prior to such event by a fraction, the numerator of
which shall be equal to the number of Common Shares outstanding immediately
prior to such event and the denominator of which shall be equal to the number of
Common Shares outstanding immediately after such event. Successive adjustments
shall be made pursuant to this Section 11(n) each time such a dividend is paid
or such a subdivision, combination or reclassification is effected. If an event
occurs that would require an adjustment under both this Section 11(n) and
Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(n)
shall be in addition to, and shall be made prior to, any adjustment required
pursuant to Section 11(a)(ii) hereof.

        Section 12. Certificate of Adjusted Exercise Price or Number of Shares
Issuable Upon Exercise of Rights. Whenever an adjustment is made as provided in
Section 11 hereof, the Company shall promptly (a) prepare a certificate setting
forth such adjustment and a brief statement of the facts giving rise to such
adjustment, (b) file with the Rights Agent and with each transfer agent for the
securities issuable upon exercise of the Rights a copy of such certificate and
(c) mail a brief summary thereof to each holder of Rights in accordance with
Section 25 hereof. Notwithstanding the foregoing sentence, the failure of the
Company to make such certification or to give such notice shall not affect the
validity or the force and effect of such adjustment. Any adjustment to be made
pursuant to Sections 11 or 13 hereof shall be effective as of the date of the
event giving rise to such adjustment. The Rights Agent shall be fully protected
in relying on any such certificate and on any adjustment therein contained, and
shall not be obligated or responsible for calculating any adjustment nor shall
it be deemed to have knowledge of such an adjustment unless and until it shall
have received such certificate.

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

        (a) In the event (a "Section 13(a) Event") that, at any time on or after
the 15% Ownership Date and prior to the earlier of the Redemption Date or the
Rights Expiration Date, (1) the Company shall, directly or indirectly,
consolidate with or merge with and into any other Person and the Company shall
not be the continuing or surviving corporation in such consolidation or merger,
(2) any Person shall, directly or indirectly, consolidate with or merge with and
into the Company and the Company shall be the continuing or surviving
corporation in such merger and, in connection with such merger, all or part of
the Common Shares shall be changed into or exchanged for stock or other
securities of any Person or cash or any other property, or (3) the Company
and/or any one or more of its Subsidiaries shall, directly or indirectly, sell
or otherwise transfer, in one or more transactions (other than transactions in
the ordinary course of business), assets or earning power aggregating more than
50% of the assets or earning power of the Company and its Subsidiaries (taken as
a whole) to any Person or Persons other than the Company or one or more of its
wholly-owned Subsidiaries (such Persons, together with the Persons described in
clauses (1) and (2) above shall be collectively referred to in this Section as
the "Surviving Person"), then, and in each such case, proper provision shall be
made so that:

               (i) except as provided in Section 7(d) hereof, each holder of a
        Right shall thereafter have the right to receive, upon the exercise
        thereof in accordance with the terms of this Agreement and payment of
        the then current Exercise Price, in lieu of the securities or other
        property otherwise purchasable upon such exercise, such number of
        validly authorized and issued, fully paid and nonassessable Common
        Shares of the Surviving Person as shall be equal to a fraction, the
        numerator of which is:

                      (A) if a Section 11(a)(ii) Event has not occurred prior to
               such Section 13(a) Event, the product of the then current
               Exercise Price multiplied by the number of one-hundredths of a
               Preferred Share purchasable upon the exercise of one Right
               immediately prior to the first Section 13(a) Event (or, if the
               Distribution Date shall not have occurred prior to the date of
               such Section 13(a) Event, the number of one-hundredths of a
               Preferred Share that would have been so purchasable if the
               Distribution Date had occurred on the Business Day immediately
               preceding the date of such Section 13(a) Event), or

                      (B) if a Section 11(a)(ii) Event has occurred prior to
               such Section 13(a) Event, the product of the Exercise Price in
               effect immediately prior to such Section 11(a)(ii) Event
               multiplied by the number of one-hundredths of a Preferred Share
               purchasable upon the exercise of one Right immediately prior to
               such Section 11(a)(ii) Event (or, if the Distribution Date shall
               not have occurred prior to the date of such Section 11(a)(ii)
               Event, the number of one-hundredths of a Preferred Share that
               would have been so purchasable if the Distribution Date had
               occurred on the Business Day immediately preceding the date of
               such Section 11(a)(ii) Event),

        and the denominator of which is 50% of the Current Market Price per
        Common Share of the Surviving Person on the date of consummation of such
        Section 13(a) Event;

               (ii) the Surviving Person 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
        the Surviving Person; and

                                       16
<PAGE>

               (iv) the Surviving Person shall take such steps (including, but
        not limited to, the reservation of a sufficient number of its Common
        Shares in accordance with Section 9 hereof) in connection with such
        consummation as may be necessary to ensure that the provisions hereof
        shall thereafter be applicable to its Common Shares thereafter
        deliverable upon the exercise of Rights.

        (b) Notwithstanding the foregoing, if the Section 13(a) Event is the
sale or transfer in one or more transactions of assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole), but less than 100% thereof, then each Person
acquiring all or a portion thereof shall assume the obligations of the Company
as to a fraction of each of the Rights equal to the fraction of the assets of
the Company and its Subsidiaries (taken as a whole) acquired by such Person, and
the obligations of the Company as to the remaining fraction of each of the
Rights shall continue to be the obligations of the Company.

        (c) The Company shall not consummate a Section 13(a) Event unless prior
thereto the Company and the Surviving Person shall have executed and delivered
to the Rights Agent a supplemental agreement confirming that such Surviving
Person shall, upon consummation of such Section 13(a) Event, assume this
Agreement in accordance with Section 13 hereof, that all rights of first refusal
or preemptive rights in respect of the issuance of Common Shares of such
Surviving Person upon exercise of outstanding Rights have been waived and that
such Section 13(a) Event shall not result in a default by such Surviving Person
under this Agreement, and further providing that, as soon as practicable after
the date of consummation of such Section 13(a) Event, such Surviving Person
shall:

               (i) prepare and file a registration statement under the
        Securities Act 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, use its best efforts to cause such
        registration statement to remain effective (with a prospectus at all
        times meeting the requirements of the Securities Act) until the Rights
        Expiration Date, and similarly comply with all applicable state
        securities laws;

               (ii) use its best efforts to list (or continue the listing of)
        the Rights and the Common Shares of the Surviving Person purchasable
        upon exercise of the Rights on a national securities exchange, or use
        its best efforts to cause the Rights and such Common Shares to meet the
        eligibility requirements for quotation on Nasdaq; and

               (iii) deliver to holders of the Rights historical financial
        statements for such Surviving Person that comply in all respects with
        the requirements for registration on Form 10 (or any successor form)
        under the Exchange Act.

        (d) In the event that at any time after the occurrence of a Section
11(a)(ii) Event some or all of the Rights shall not have been exercised pursuant
to Section 11 hereof prior to the date of a Section 13(a) Event, such Rights
shall thereafter be exercisable only in the manner described in Section 13(a)
hereof. In the event that a Section 11(a)(ii) Event occurs on or after the date
of a Section 13(a) Event, Rights shall not be exercisable pursuant to Section 11
hereof but shall instead be exercisable pursuant to, and only pursuant to, this
Section 13.

        (e) The provisions of this Section 13 shall apply to each successive
merger, consolidation, sale or other transfer constituting a Section 13(a)
Event.

        Section 14. Fractional Rights and Fractional Shares.

        (a) The Company shall not be required to issue fractions of Rights or to
distribute Right Certificates that represent fractional Rights. If the Company
shall determine not to issue such fractional Rights, the Company shall pay to
the registered holders of the Right Certificates with respect to which such
fractional Rights would otherwise be issuable, at the time such fractional
Rights would otherwise have been issued as provided herein, an amount in cash
equal to the same fraction of the Current Market Price of a whole Right on the
Business Day immediately prior to the date upon which such fractional Rights
would otherwise have been issuable.

        (b) The Company shall not be required to issue fractions of Common
Shares or Preferred Shares upon exercise of Rights (other than fractions that
are integral multiples of one one-hundredth of a Preferred Share), or to
distribute certificates that represent fractional Common Shares or Preferred
Shares (other than fractions that are integral multiples of one one-hundredth of
a Preferred Share). Fractions of Preferred Shares in integral multiples of one
one-hundredth of a Preferred Share may, at the election of the Company, be
represented 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
Preferred Shares. If the Company shall determine not to issue fractional Common
Shares or Preferred Shares (or depositary receipts in lieu of Preferred Shares),
the Company shall pay to the registered holders of Right Certificates to whom
such fractional Common Shares or Preferred Shares would otherwise be issuable,
at the time such Rights are exercised as provided herein, an amount in cash
equal to the same fraction of the Current Market Price of a whole Common Share
or Preferred Share, as the case may be. For purposes of this Section 14(b), the
Current Market Price of a whole Common Share or Preferred Share shall be the
Closing Price per share for the Trading Day immediately prior to the date of
such exercise.

        (c) The holder of a Right, by the acceptance of such Right, expressly
waives such holder's right to receive any fractional Rights or any fractional
Common Shares or Preferred Shares upon exercise of such 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 hereof, are vested in the respective registered holders of the Right
Certificates and certificates for Common Shares representing Rights, and any
registered holder of any Right Certificate or of such certificate for Common
Shares, without the consent of the Rights Agent or of the holder of any other
Right Certificate or any other certificate for Common Shares may, in such
holder's own behalf and for such holder's own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act in respect of, such holder's right to exercise the
Rights represented by such Right Certificate or by such certificate for Common
Shares in the manner provided in such 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, and injunctive relief against actual or threatened violations, of
the obligations of any Person under 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 every other holder of a Right that:

               (a) prior to the Distribution Date, the Rights shall be
        represented by certificates for Common Shares registered in the name of
        the holders of such Common Shares (which certificates

                                       18
<PAGE>

        for Common Shares shall also constitute Right Certificates), and each
        such Right shall be transferable only in connection with the transfer of
        such Common Shares;

               (b) after the Distribution Date, the Right Certificates shall
        only be transferable on the registry books of the Rights Agent if
        surrendered at the principal office of the Rights Agent, duly endorsed
        or accompanied by a proper instrument of transfer;

               (c) the Company and the Rights Agent may deem and treat the
        Person in whose name the Right Certificate is registered as the absolute
        owner thereof and of the Rights represented thereby for all purposes
        whatsoever (notwithstanding any notations of ownership or writing on the
        Right Certificate by anyone other than the Company or the Rights Agent),
        and neither the Company nor the Rights Agent shall be affected by any
        notice to the contrary; and

               (d) notwithstanding anything in this Agreement to the contrary,
        neither the Company nor the Rights Agent shall have any liability to any
        holder of a Right or other Person as a result of its inability to
        perform any of its obligations under this Agreement by reason of any
        preliminary or permanent injunction or other order, decree, judgment or
        ruling (whether interlocutory or final) issued by a court of competent
        jurisdiction or by a governmental, regulatory or administrative agency
        or commission, or any statute, rule, regulation or executive order
        promulgated or enacted by any governmental authority, prohibiting or
        otherwise restraining performance of such obligation; provided, however,
        that the Company must use commercially reasonable efforts to have any
        such order, decree, judgment or ruling lifted, rescinded or otherwise
        overturned as soon as possible.

        Section 17. Right Holder and Right Certificate Holder Not Deemed a
Stockholder. No holder, as such, of any Right or Right Certificate shall be
entitled to vote, receive dividends or be deemed for any purpose the holder of
the securities of the Company that may at any time be issuable upon 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 or 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, to give or withhold consent to any
corporate action, to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, in each case until such Right or the
Rights represented by such Right Certificate shall have been exercised in
accordance with the provisions hereof.

        Section 18. Concerning the Rights Agent.

        (a) The Company shall pay to the Rights Agent as compensation for all
services rendered by the Rights Agent hereunder such fees as the Company and the
Rights Agent have agreed upon in writing (by confirming letter or otherwise) or,
if no such agreement has been made, reasonable and customary fees and expenses
including any 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 Rights Agent 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 reasonable costs and expenses of defending
against any claim of liability arising under this Agreement. The indemnification
provided for hereunder shall survive the expiration of the Rights and the
termination of this Agreement.

        (b) The Rights Agent may conclusively rely upon and shall be protected
and shall incur no liability for or in respect of any action taken, suffered or
omitted by it in connection with its

                                       19
<PAGE>

administration of this Agreement in reliance upon any Right Certificate or
certificate for Preferred Shares or Common Shares or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement or other
paper or document believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged, by the proper Person or Persons, or
otherwise upon the advice of its counsel as set forth in Section 20 hereof.

        (c) Notwithstanding anything in this Agreement to the contrary, in no
event shall the Rights Agent be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Rights Agent has been advised of the likelihood of such
loss or damage and regardless of the form of the action.

        Section 19. Merger or Consolidation or Change of Name of Rights Agent.

        (a) Any corporation into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any corporation 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 would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
hereof. If, 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
Certificates so countersigned; and if 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 such Right Certificate and in
this Agreement.

        (b) If 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 if 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
and effect provided in such Right Certificate and in this Agreement.

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

               (a) Before the Rights Agent acts or refrains from acting, it may
        consult with legal counsel (who may be legal counsel for the Company),
        and the advice or 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 advice or
        opinion.

               (b) 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, the Chief

                                       20
<PAGE>

        Executive Officer, the President, any Vice President, the Treasurer, the
        Secretary or any 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.

               (c) The Rights Agent shall be liable hereunder to the Company and
        any other Person only for its own negligence, bad faith or willful
        misconduct.

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

               (e) 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 authorization, execution and delivery hereof by
        the Rights Agent) or in respect of the validity or execution of any
        Right Certificate (except its countersignature thereof); nor shall the
        Rights Agent be responsible for any breach by the Company of any
        covenant or condition contained in this Agreement or in any Right
        Certificate; nor shall the Rights Agent be responsible for any change in
        the exercisability of the Rights (including any Rights becoming null and
        void pursuant to Section 7(d) hereof) or any adjustment in the terms of
        the Rights (including the manner, method or amount thereof) provided for
        in Sections 7, 11, 13 and 23 hereof, or the ascertaining of the
        existence of facts that would require any such change or adjustment
        (except with respect to the exercise of Rights represented by Right
        Certificates after actual notice that such change or adjustment is
        required); nor shall the Rights Agent by any act hereunder be deemed to
        make any representation or warranty as to the authorization or
        reservation of any Preferred Shares or Common Shares or other securities
        to be issued pursuant to this Agreement or any Right Certificate, or as
        to whether any Preferred Shares or Common Shares or other securities
        will, when issued, be validly authorized and issued, fully paid and
        nonassessable.

               (f) 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.

               (g) 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, the Chief Executive Officer,
        the President, any Vice President, the Chief Financial Officer, the
        Secretary, the Assistant Secretary or the Treasurer of the Company, and
        to apply to such officers for advice or instructions in connection with
        its duties under this Agreement, and the Rights Agent 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 those 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 under this Agreement and the
        date on or after which such action shall be taken or such omission shall
        be effective. The Rights Agent shall not be liable 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 in such
        application (which date shall not be less than ten Business Days after
        the date any officer of the Company actually receives such application,
        unless any such officer shall have consented in writing to an earlier
        date) unless, prior to taking any such action (or the effective date in
        the case of an omission), the Rights Agent

                                       21
<PAGE>

        shall have received written instructions from the Company in response to
        such application to the contrary.

               (h) 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 take a pecuniary interest 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 the 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 Person.

               (i) 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, default, neglect or
        misconduct of any such attorneys or agents or for any loss to the
        Company resulting from any such act, default, neglect or misconduct,
        provided that reasonable care was exercised in the selection and
        continued employment thereof.

               (j) The Rights Agent shall not be required to take notice or be
        deemed to have notice of any fact, event or determination (including,
        without limitation, any dates or events defined in this Agreement or the
        designation of any Person as a 15% Stockholder, Affiliate or Associate)
        under this Agreement unless and until the Rights Agent is specifically
        notified in writing by the Company of such fact, event or determination.

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

        Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon 30-days' advance notice in writing mailed to the Company and to each
transfer agent of the Common Shares and Preferred Shares by registered or
certified mail, and, at the expense of the Company to the holders of the Right
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor Rights Agent upon 30-days' advance 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 Preferred Shares 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
as such, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of 30 days after
giving notice of such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Right Certificate (who shall, with such notice, submit such
holder's Right Certificate for inspection by the Company), then the Company
shall become the Rights Agent and 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, in good standing and doing
business under the laws of the United States or of the States of New York or
California (or of any other state of the United States so long as such
corporation is authorized to do business as a banking institution in the States
of New York or California), in good standing, having a principal office in New
York or California, that is authorized under such laws to exercise corporate
trust or stock transfer powers and is subject to supervision or examination by
federal or state authority and that has at the time of its appointment as Rights
Agent a combined capital and surplus of at least $50,000,000. After appointment,

                                       22
<PAGE>

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 the predecessor
Rights Agent hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose of this Agreement and so that
the successor Rights Agent may appropriately act as Rights Agent hereunder. 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 Preferred Shares, and mail a notice thereof in
writing to the registered holders of the Right Certificates. Failure to give any
notice provided for in this Section 21, however, or any defect therein, shall
not affect the legality or validity of the resignation or removal of the
predecessor 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 Right Certificates to the contrary,
the Company may, at its option, issue new Right Certificates in such form as may
be approved by the Board of Directors in order to reflect any adjustment or
change in the Exercise Price and the number or kind or class of shares or other
securities or property purchasable upon exercise of the Rights in accordance
with the provisions of this Agreement.

        Section 23. Redemption of Rights.

        (a) Until the earliest of (i) the date of the first Section 11(a)(ii)
Event, (ii) the date of the first Section 13(a) Event or (iii) the Rights
Expiration Date, the Board of Directors of the Company may, at its option,
authorize and direct the redemption of all, but not less than all, of the then
outstanding Rights at a redemption price of $0.001 per Right, as such redemption
price shall be appropriately adjusted to reflect any stock split, stock dividend
or similar transaction occurring after the date hereof (the "Redemption Price"),
and the Company shall so redeem the Rights.

        (b) Immediately upon the action of the Board of Directors of the Company
authorizing and directing the redemption of the Rights pursuant to subsection
(a) of this Section 23, or at such time and date thereafter as the Board of
Directors of the Company may specify, and without any further action and without
any notice, the right to exercise Rights shall terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
Within ten Business Days after the date of such action, the Company shall give
notice of such redemption to the holders of Rights by mailing such notice to all
holders of Rights at their last addresses as they appear upon the registry books
of the Rights Agent or, if prior to the Distribution Date, on the registry books
of the transfer agent for the Common Shares. Any notice that is mailed in the
manner herein provided shall be deemed given, whether or not the holder receives
such notice; provided, however, that neither the failure to give any such notice
nor any defect therein shall affect the legality or validity of such redemption.
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, directly or indirectly, redeem, acquire or purchase for value
any Rights in any manner other than (i) in the manner specifically set forth in
Section 24 hereof (ii) in the manner specifically set forth in this Section 23
or (iii) in connection with the purchase of Common Shares prior to the earlier
of the date of the first Section 11(a)(ii) Event or the date of the first
Section 13(a) Event.

        (c) The Company may, at its option, pay the Redemption Price in cash,
Common Shares, Preferred Shares, other equity securities of the Company, debt
securities of the Company, other property or any combination of the foregoing,
in each case having an aggregate Current Market Price on the Redemption Date
equal to the Redemption Price.

        Section 24. Exchange of Rights.

        (a) At any time during the period of 180 days after a Section 11(a)(ii)
Event, the Board of Directors of the Company may, at its option, authorize and
direct the exchange of all, but not less than all, of the then outstanding
Rights (other than Rights that have become null and void pursuant to Section
7(d)) for Common Shares, one one-hundredths of Preferred Shares, debt securities
of the Company, other property, or any combination of the foregoing, in each
case having an aggregate Current Market Price per Right equal to the result
obtained by (i) multiplying the Current Market Price per Common Share on the
record date for such exchange by the number of Common Shares for which a Right
is exercisable on such record date and (ii) subtracting from such product the
Exercise Price on such Record Date (the "Exchange Ratio"), and the Company shall
so exchange the Rights.

        (b) Immediately upon the action of the Board of Directors of the Company
authorizing and directing the exchange of the Rights pursuant to Section 24(a),
or at such time and date thereafter as the Board of Directors of the Company may
specify, and without any further action and without any notice, the right to
exercise Rights shall terminate and the only right thereafter of the holders of
Rights shall be to receive the securities and other property described in
Section 24(a) in accordance with the Exchange Ratio. Within ten Business Days
after the date of such action, the Company shall give notice of such exchange to
the holders of Rights by mailing such notice to all holders of Rights at their
last addresses as they appear upon the registry books of the Rights Agent or, if
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Shares. Any notice that is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives such notice, but neither the
failure to give any such notice nor any defect therein shall affect the legality
or validity of such exchange. Each such notice of exchange shall state the
method by which the Rights will be exchanged.

        (c) Notwithstanding the foregoing, in the event that the Board of
Directors directs the exchange of the outstanding Rights for Common Shares but
the aggregate number of Common Shares that are authorized by the Company's
Certificate of Incorporation, as amended from time to time, but not outstanding
or reserved for issuance for purposes other than upon exercise or exchange of
the Rights is less than the aggregate number of Common Shares issuable upon the
exchange of the Rights in accordance with this Section 24 (the excess of such
number of authorized Common Shares over and above such number of issuable Common
Shares being hereinafter referred to as the "Unavailable Exchange Shares"), then
the Company shall substitute for the pro rata portion of the Unavailable
Exchange Shares that would otherwise be issuable upon the exchange of the Rights
in accordance with this Section 24 (i) cash, (ii) other equity securities of the
Company (including, without limitation, Common Share Equivalents), (iii) debt
securities of the Company, (iv) other property or (v) any combination of the
foregoing, in each case having an aggregate Current Market Price equal to the
aggregate Current Market Price of the Unavailable Exchange Shares for which
substitution is made. Subject to Section 7(d) hereof, in the event that the
Company takes any action pursuant to this Section 24, such action shall apply
uniformly to all outstanding Rights.

        Section 25. Notice of Certain Events.

        (a) In the event that the Company shall propose (i) to declare or pay
any dividend on or make any distribution with respect to its Common Shares or
Preferred Shares (other than a regular quarterly cash dividend), (ii) to offer
to the holders of its Common Shares or Preferred Shares options, rights or
warrants to subscribe for or to purchase any additional shares thereof or shares
of stock of any class or any other securities, rights or options, (iii) to
effect any reclassification of its Common Shares or Preferred Shares (other than
a reclassification involving only the subdivision of outstanding shares), (iv)
to effect any consolidation or merger with or into, 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 more

                                       24
<PAGE>

than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to, any other Person or Persons, or (v) to effect the
liquidation, dissolution or winding up of the Company, then and in each such
case, the Company shall give to each holder of a Right Certificate, in
accordance with Section 26 hereof, a notice of such proposed action that shall
specify the record date for the purpose of such dividend or distribution, or the
date upon 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 record of the Common Shares or Preferred
Shares, if any such date is to be fixed, and such notice shall be so given in
the case of any action covered by clause (i) or (ii) above at least 20 days
prior to the record date for determining holders of the Common Shares or
Preferred Shares for purposes of such action, and in the case of any such other
action, at least 20 days prior to the earlier of the date of the taking of such
proposed action or the date of participation therein by the holders of the
Common Shares or Preferred Shares. The failure to give the notice required by
this Section 25 or any defect therein shall not affect the legality or validity
of the action taken by the Company or the vote upon any such action.

        (b) Upon the occurrence of each Section 11(a)(ii) Event and each Section
13(a) Event, the Company shall as soon as practicable thereafter give to each
holder of a Right Certificate, in accordance with Section 26 hereof, a notice of
the occurrence of such event, specifying the event and the consequences of the
event to holders of Rights under Sections 11 and 13 hereof.

        Section 26. Notices. Notices or demands authorized by this Agreement to

        Section 27. Supplements and Amendments.

        (a) The Board of Directors of the Company may, from time to time,
without the approval of any holders of Rights, supplement or amend any provision
of this Agreement in any manner, whether or

                                       25
<PAGE>

not such supplement or amendment is adverse to any holder of Rights, and direct

after the earliest of (i) the date of the first Section 11(a)(ii) Event, (ii)

        (b) From and after the earlier of the date of the first Section
11(a)(ii) Event or the date of the first Section 13(a) Event and prior to the
Rights Expiration Date, the Company shall not effect any amendment to the
Certificate of Designations for the Preferred Shares that would materially and

outstanding Rights. Notwithstanding anything in this Agreement to the contrary,
no supplement or amendment that changes the rights and duties of the Rights
Agent under this Agreement in any manner adverse to the Rights Agent will be
effective against the Rights Agent without the execution of such supplement or
amendment by the Rights Agent.

        Section 28. Certain Covenants. Subject to Section 27 hereof and the

adversely affect the value of the Rights.

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 permitted assigns
hereunder.

        Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Right Certificates (other than those representing
Rights that have become null and void) and the certificates for Common Shares
representing Rights (other than those Rights that have become null and void) any
legal or equitable right, remedy or claim under this Agreement, and this
Agreement shall be for the sole and exclusive benefit of the Company, the Rights
Agent and such registered holders of Right Certificates and certificates for

with the Form of Election to Purchase duly executed. The number of Rights
evidenced by this Right Certificate (and the number of Preferred Shares that may
be purchased upon exercise thereof) set forth above, and the Exercise Price per
share set forth above, are the number and Exercise Price as of March 8, 2002,
based on the Preferred Shares as constituted at such date.

        As provided in the Rights Agreement, the Exercise Price and the number
of Preferred Shares that may be purchased upon the exercise of the Rights
evidenced by this Right Certificate are subject to modification and adjustment
upon the happening of certain events. This Right Certificate is subject to all
of the terms, provisions and conditions of the Rights Agreement, which terms,
provisions and conditions are hereby incorporated herein by reference and made a
part hereof and to which Rights Agreement reference is hereby made for a full
description of the rights, limitations of rights, obligations, duties and
immunities hereunder of the Rights Agent, the Company and the holders of the
Rights Certificates. Copies of the Rights Agreement are on file at the principal
executive offices of I-Flow Corporation and the above-mentioned offices of the
Rights Agent.

        This Right Certificate, with or without other Right Certificates, upon
surrender at the office or agency of the Rights Agent at American Stock Transfer
& Trust Company, 59 Maiden Lane, New York, NY 10038, Attn: Corporate Trust
Department, may be exchanged for another Right Certificate or Right Certificates
of like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of Preferred Shares as the Rights evidenced by the Right
Certificate or Right Certificates surrendered shall have entitled such holder to
purchase. If this Right Certificate shall be exercised in part, the holder shall
be entitled to receive upon surrender hereof another Right Certificate or Right
Certificates for the number of whole Rights not exercised. Subject to the
provisions of the Rights Agreement, the Rights evidenced by this Certificate
may, but are not required to, be redeemed by the Company at a redemption price
of $0.001 per Right.

        No fractional Preferred Shares will be issued upon the exercise of any
Right or Rights evidenced hereby (other than fractions that are integral
multiples of one one-hundredth of a Preferred Share, which may, at the election
of the Company, be evidenced by depositary receipts), but in lieu thereof, a
cash payment will be made, as provided in the Rights Agreement.

        No holder of this Right Certificate shall be entitled to vote or receive
dividends or be deemed for any purpose the holder of the Preferred Shares or of
any other securities of the Company that may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a

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

                         PURSUANT TO SECTION 151 OF THE
                GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

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

        I-Flow Corporation, a Delaware corporation (the "Corporation"),
certifies that pursuant to the authority conferred upon the Board of Directors
of the Corporation (the "Board of Directors") by the Certificate of
Incorporation of the Corporation (the "Certificate of Incorporation"), and in
accordance with the provisions of Section 151 of the General Corporation Law of
the State of Delaware, as amended, the Board of Directors, on February 26, 2002,
adopted the following resolution creating a series of its Preferred Stock, par
value $.001 per share:

        RESOLVED, that (1) pursuant to the authority conferred upon the Board of
Directors of the Corporation by the Certificate of Incorporation of the
Corporation, the Board of Directors hereby designates 300,000 shares of the
preferred stock, par value $.001 per share, of the Corporation as "Series A
Junior Participating Cumulative Preferred Stock" (the "Preferred Shares"), and
the powers, designations, preferences and relative, participating, optional and
other rights of the Preferred Shares and the qualifications, limitations and
restrictions thereof, be, and they hereby are, as set forth below (the
"Certificate of Designation") and (2) in connection therewith, the officers of
the Corporation be, and each of them hereby is, authorized, empowered and
directed on behalf of the Corporation and in its name to execute and file the
Certificate of Designation with the Delaware Secretary of State:

        Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Cumulative Preferred Stock" and the
number of shares constituting such series so designated shall be 300,000 (the
"Series A Preferred Stock"). Such number of shares may be increased or decreased
by resolution of the Board of Directors; provided, however, 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.

<PAGE>

        Section 2. Dividends and Distributions.

        (a) Subject to the rights of the holders of any shares of any series of
preferred stock of the Corporation, par value $.001 per share ("Preferred
Stock")(or any similar stock) 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 shares of common stock of the
Corporation, par value $.001 per share (the "Common Stock"), and of any other
junior stock, shall be entitled to receive, when, as and if declared by the
Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the tenth 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 (i) $0.25 per share ($1.00 per annum) or (ii) 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 or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such event the
amount to which the holder of each share of Series A Preferred Stock was
entitled immediately prior to such event under clause (ii) 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 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, however,
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 $0.25 per
share ($1.00 per annum) 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 event 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

                                       2
<PAGE>

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 cumulate but 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 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 or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock outstanding
immediately prior to such event.

        (b) Except as otherwise provided herein, in the Corporation's
Certificate of Incorporation, as amended (the "Charter"), in any other
certificate of designation 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 authorized or declared, on shares of Series A Preferred Stock outstanding
shall have been paid in full, the Corporation shall not, directly or indirectly:

                                       3
<PAGE>

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

               (ii) authorize, declare or pay dividends on, or make any other
distributions with respect to, 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 (either as to dividends or upon liquidation, dissolution 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, directly or indirectly, 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
Charter, in any other certificate of designation creating a series of Preferred
Stock or any similar stock or as otherwise required by law.

        Section 6. Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made to:
(i) 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 the greater of (A) $1.00 per share ($0.01 per one one-hundredth of
a share), plus an amount equal to accrued and unpaid dividends and distributions
thereon, whether or not declared, to the date of such payment, or (B) an
aggregate amount per share, subject to the provision for adjustment hereinafter
set forth, equal to 100 times the aggregate amount to be

                                       4
<PAGE>

distributed per share of Common Stock to holders thereof; or (ii) 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 or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such event the
aggregate amount to which each holder of a share of Series A Preferred Stock was
entitled immediately prior to such event under clause (i) 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 outstanding immediately prior to such event.

        Section 7. Consolidation, Merger or Other. In the event 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 or otherwise changed, then in any
such event 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 or combination or consolidation of the outstanding shares
of Common Stock (by reclassification or otherwise than by payment of a dividend
in shares of Common Stock) into a greater or lesser number of shares of Common
Stock, then in each such event the amount set forth in the preceding sentence
with respect to the exchange or change of shares of Series A Preferred Stock
shall be adjusted by multiplying such amount by a fraction, the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event, and the denominator of which is the number of shares of Common Stock
outstanding immediately prior to such event.

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

        Section 9. Rank. The Series A Preferred Stock shall rank, with respect
to the payment of dividends and the distribution of assets, junior to all series
or classes of the Corporation's Preferred Stock whether issued before or after
the issuance of the Series A Preferred Stock.

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