                          STOCKHOLDER RIGHTS AGREEMENT

      STOCKHOLDER RIGHTS AGREEMENT, dated as of March 24, 2005 (the
"Agreement"), between OXiGENE, INC., a Delaware corporation (the "Company"), and
American Stock Transfer & Trust Company, as Rights Agent (the "Rights Agent").

                                   WITNESSETH

      WHEREAS, on March 24, 2005 (the "Rights Dividend Declaration Date"), the
Board of Directors of the Company (the "Board") authorized and declared a
dividend distribution of one Right (a "Right") for each share of Common Stock
(as hereinafter defined) of the Company outstanding at the close of business on
April 4, 2005 (the "Record Date"), and has authorized the issuance of one Right
(as such number may hereinafter be adjusted pursuant to the provisions hereof)
for each share of Common Stock of the Company issued (whether originally issued
or delivered from the Company's treasury) between the Record Date and the
Distribution Date, each Right initially representing the right to purchase one
share of Common Stock upon the terms and conditions hereinafter set forth (the
"Rights");

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

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

            (a) "Acquiring Person" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 15% or more of the shares of Common Stock then outstanding, but shall not
include the Company, any Subsidiary of the Company, any employee benefit plan or
employee stock plan of the Company or of any Subsidiary of the Company, or any
Person or entity organized, appointed or established by the Company for or
pursuant to the terms of any such plan; provided, however, that (i) if the Board
determines in good faith that a Person who would otherwise be an "Acquiring
Person" became inadvertently the Beneficial Owner of a number of shares of
Common Stock such that the Person would otherwise qualify as an "Acquiring
Person" (including, without limitation, because (A) such Person was unaware that
it beneficially owned a percentage of Common Stock that would otherwise cause
such Person to be an "Acquiring Person" or (B) such Person was aware of the
extent of its Beneficial Ownership of Common Stock but had no actual knowledge
of the consequences of such Beneficial Ownership under this Agreement) and
without any intention of changing or influencing control of the Company, then
such Person shall not be deemed to be or to have become an "Acquiring Person"
for any purposes of this Agreement unless and until such Person shall have
failed to divest itself, as soon as practicable (as determined, in good faith,
by the Board), of Beneficial Ownership of a sufficient number of shares of
Common Stock so that such Person would no longer otherwise qualify as an
"Acquiring Person"; (ii) if, as of the date hereof or prior to the first public
announcement of the adoption of this Agreement,

<PAGE>

any Person is or becomes the Beneficial Owner of 15% or more of the shares of
Common Stock outstanding, such Person shall not be deemed to be or to become an
"Acquiring Person" unless and until such time as such Person shall, after the
first public announcement of the adoption of this Agreement, become the
Beneficial Owner of an additional 1% or more of the shares of Common Stock
outstanding (other than pursuant to a dividend or distribution paid or made by
the Company on the outstanding Common Stock or pursuant to a split or
subdivision of the outstanding Common Stock), unless, upon becoming the
Beneficial Owner of such additional shares of Common Stock, such Person is not
then the Beneficial Owner of 15% or more of the shares of Common Stock then
outstanding; and (iii) no Person shall become an "Acquiring Person" as the
result of an acquisition of shares of Common Stock by the Company which, by
reducing the number of shares outstanding, increases the proportionate number of
shares of Common Stock beneficially owned by such Person to 15% or more of the
shares of Common Stock then outstanding; provided, however, that if a Person
shall become the Beneficial Owner of 15% or more of the shares of Common Stock
then outstanding by reason of such share acquisitions by the Company and shall
thereafter become the Beneficial Owner of an additional 1% or more of the shares
of Common Stock outstanding (other than pursuant to a dividend or distribution
paid or made by the Company on the outstanding Common Stock or pursuant to a
split or subdivision of the outstanding Common Stock), then such Person shall be
deemed to be an "Acquiring Person" unless upon becoming the Beneficial Owner of
such additional shares of Common Stock such Person does not beneficially own 15%
or more of the shares of Common Stock then outstanding. For all purposes of this
Agreement, any calculation of the number of shares of Common Stock outstanding
at any particular time, including for purposes of determining the particular
percentage of such outstanding shares of Common Stock of which any Person is the
Beneficial Owner, shall be made in accordance with the last sentence of Rule
13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act (as
such term is hereinafter defined).

            (b) "Act" shall mean the Securities Act of 1933, as amended.

            (c) "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Securities Exchange Act of 1934, as amended and in effect on the date of
this Agreement (the "Exchange Act"); provided that, for the purpose of
determining whether a Person is an "Affiliate" or "Associate" of an executive
officer of the Corporation, the definitions of "Affiliate" and "Associate" shall
not include any relative of such executive officer other than his or her spouse,
children or grandchildren.

            (d) "Agreement" shall mean this Stockholder Rights Agreement as
originally executed or as it may from time to time be supplemented or amended
pursuant to the applicable provisions hereof.

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

                  (i) which such Person or any of such Person's Affiliates or
Associates, directly or indirectly, has the right to acquire (whether such right
is exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or understanding, whether or not in writing, or upon the
exercise of conversion rights, exchange rights, other rights, warrants or
options, or otherwise; provided, however, that a Person shall not be deemed the
"Beneficial Owner" of, or to "beneficially own", (A) securities tendered
pursuant to a tender offer or exchange offer made by such Person or any of such
Person's Affiliates or

                                       2
<PAGE>

Associates until such tendered securities are accepted for purchase or exchange,
or (B) securities issuable upon exercise of Rights at any time prior to the
occurrence of a Triggering Event, or (C) securities issuable upon exercise of
Rights from and after the occurrence of a Triggering Event which Rights were
acquired by such Person or any of such Person's Affiliates or Associates prior
to the Distribution Date or pursuant to Section 3(a) or Section 22 hereof (the
"Original Rights") or pursuant to Section 11(a)(i) hereof in connection with an
adjustment made with respect to any Original Rights;

                  (ii) which such Person or any of such Person's Affiliates or
Associates, directly or indirectly, has the right to vote or dispose of or has
"beneficial ownership" of (as determined pursuant to Rule 13d-3 of the General
Rules and Regulations under the Exchange Act, or any comparable or successor
rule), including pursuant to any agreement, arrangement or understanding,
whether or not in writing; provided, however, that a Person shall not be deemed
the "Beneficial Owner" of, or to "beneficially own", any security under this
subparagraph (ii) as a result of an agreement, arrangement or understanding to
vote such security if such agreement, arrangement or understanding: (A) arises
solely from a revocable proxy or consent given in response to a public proxy or
consent solicitation made pursuant to, and in accordance with, the applicable
provisions of the General Rules and Regulations under the Exchange Act, and (B)
is not also then reportable by such Person on Schedule 13D under the Exchange
Act (or any comparable or successor report); or

                  (iii) which are beneficially owned, directly or indirectly, by
any other Person (or any Affiliate or Associate thereof) and with respect to
which such Person (or any of such Person's Affiliates or Associates) has any
agreement, arrangement or understanding, whether or not in writing, for the
purpose of acquiring, holding, voting (except pursuant to a revocable proxy as
described in the proviso to subparagraph (ii) of this paragraph (e)) or
disposing of such securities of the Company (a joint filing of a Schedule 13D
under the Exchange Act or any comparable or successor report being deemed to be
conclusive evidence of such an agreement, arrangement or understanding);
provided, however, that nothing in this paragraph (e) shall cause a Person
engaged in business as an underwriter of securities to be the "Beneficial Owner"
of, or to "beneficially own", any securities acquired through such Person's
participation in good faith in a firm commitment underwriting until the
expiration of forty (40) days after the date of such acquisition.

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

            (f) "Board" shall have the meaning set forth in the preamble of the
Agreement.

Person would be the Beneficial Owner of 15% or more of the shares of Common
Stock then outstanding (the earlier of (i) or (ii) being herein referred to as
the "Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of paragraph (b) of this Section 3) by the certificates for the
Common Stock registered in the names of the holders of the Common Stock (which
certificates for Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company). As soon as practicable after
the Distribution Date and upon receipt of all necessary information, the Rights
Agent will send by first-class, insured, postage prepaid mail, to each record
holder of the Common Stock as of the Close of Business on the Distribution Date
(other than to any Acquiring Person or any Associate or Affiliate of an
Acquiring Person) at the address of such holder shown on the records of the
Company, one or more rights certificates, in the form specified in Section 4
hereof (the "Rights Certificates"), evidencing one Right for each share of
Common Stock so held, subject to adjustment as provided herein. In the event
that an adjustment in the number of Rights per share of Common Stock has been
made pursuant to this Agreement, at the time of distribution of the Rights
Certificates, the Company shall make the necessary and appropriate rounding
adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are

                                       6
<PAGE>

distributed and cash is paid in lieu of any fractional rights. As of and after
the Distribution Date, the Rights will be evidenced solely by such Rights
Certificates.

            (b) As promptly as practicable following the Record Date, the
Company will send a copy of a Summary of Rights, in substantially the form
attached hereto as Exhibit A, by first-class, postage prepaid mail, to each
record holder of the Common Stock as of the Close of Business on the Record Date
(other than to any Acquiring Person or any Associate or Affiliate of an
Acquiring Person) at the address of such holder shown on the records of the
Company. With respect to certificates for the Common Stock outstanding as of the
Record Date, until the Distribution Date, the Rights will be evidenced by such
certificates for the Common Stock together with the Summary of Rights and the
registered holders of the Common Stock shall also be the registered holders of
the associated Rights. Until the earlier of the Distribution Date or the
Expiration Date (as such term is defined in Section 7 hereof), the transfer of
any certificates representing shares of Common Stock, with or without a copy of
the Summary of Rights, shall also constitute the transfer of the Rights
associated with the shares of Common Stock represented by such certificates.

            (c) Rights shall be issued in respect of all shares of Common Stock
that are issued (whether originally issued or from the Company's treasury) after
the Record Date but prior to the earlier of the Distribution Date or the
Expiration Date. Rights shall also be issued to the extent provided in Section
22 in respect of all shares of Common Stock which are issued (whether originally
issued or from the Company's treasury) after the Distribution Date and prior to
the Expiration Date. Certificates representing such shares of Common Stock in
respect of which Rights are issued pursuant to the first sentence of this
Section 3(c) shall also be deemed to be certificates for Rights, and commencing
as soon as reasonably practicable following the date hereof shall bear the
following legend:

            This certificate also evidences and entitles the holder hereof to
            certain Rights as set forth in the Stockholder Rights Agreement
            between OXiGENE, Inc. (the "Company") and American Stock Transfer &
            Trust Company (the "Rights Agent") dated as of March 24, 2005 (the
            "Rights Agreement"), the terms of which are hereby incorporated
            herein by reference and a copy of which is on file at the principal
            offices of the Company. Under certain circumstances, as set forth in
            the Rights Agreement, such Rights will be evidenced by separate
            certificates and will no longer be evidenced by this certificate.
            The Company will mail to the holder of this certificate a copy of
            the Rights Agreement, as in effect on the date of mailing, without
            charge promptly after receipt of a written request therefor. UNDER
            CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS
            ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN
            ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE OF AN ACQUIRING
            PERSON (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), WHETHER
            CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY SUBSEQUENT
            HOLDER, WILL BECOME NULL AND VOID. THE RIGHTS SHALL NOT BE
            EXERCISABLE, AND SHALL BE VOID SO LONG AS HELD, BY A HOLDER IN ANY
            JURISDICTION WHERE THE REQUISITE QUALIFICATION TO THE ISSUANCE TO
            SUCH HOLDER, OR THE EXERCISE BY SUCH HOLDER, OF THE RIGHTS IN SUCH
            JURISDICTION SHALL NOT HAVE BEEN OBTAINED OR BE OBTAINABLE.

                                       7
<PAGE>

With respect to such certificates containing the foregoing legend, until the
earlier of (i) the Distribution Date or (ii) the Expiration Date, the Rights
associated with the Common Stock represented by such certificates shall be
evidenced by such certificates alone and registered holders of Common Stock
shall also be the registered holders of the associated Rights, and the transfer
of any of such certificates shall also constitute the transfer of the Rights
associated with the Common Stock represented by such certificates.
Notwithstanding the foregoing, the omission of a legend shall not affect the
enforceability of any part of this Agreement or the rights of any holder of the
Rights.

      Section 4. Form of Rights Certificates. The Rights Certificates (and the
forms of election to purchase and of assignment to be printed on the reverse
thereof) shall each be substantially in the form set forth in Exhibit B hereto
and may have such marks of identification or designation and such legends,
summaries or endorsements printed thereon as the Company may deem appropriate
(but which do not affect the rights, duties or responsibilities of the Rights
Agent) and as are not inconsistent with the provisions of this Agreement, or as
may be required to comply with any applicable law or with any rule or regulation
made pursuant thereto or with any rule or regulation of any stock exchange or
trading market on which the Rights may from time to time be listed, or to
conform to usage. Subject to the provisions hereof, the Rights Certificates,
whenever distributed, shall be dated as of the Record Date and on their face
shall entitle the holders thereof to purchase such number of shares of Common
Stock as shall be set forth therein at the price per share set forth therein
(such exercise price per share of Common Stock hereinafter referred to as the
"Purchase Price"), but the amount and type of securities purchasable upon the
exercise of each Right and the Purchase Price thereof shall be subject to
adjustment as provided herein.

      Section 5. Countersignature and Registration.

            (a) The Rights Certificates shall be executed on behalf of the
Company by its Chief Executive Officer and President, Chief Financial Officer or
any Vice President, either manually or by facsimile signature, and shall have
affixed thereto the Company's seal or a facsimile thereof which shall be
attested by the Secretary or an Assistant Secretary of the Company, either
manually or by facsimile signature. The Rights 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 Rights Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Rights Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the person who signed such Rights Certificates had not ceased to be such officer
of the Company; and any Rights Certificates may be signed on behalf of the
Company by any person who, at the actual date of the execution of such Rights
Certificate, shall be a proper officer of the Company to sign such Rights
Certificate, although at the date of the execution of this Agreement any such
person was not such an officer.

            (b) Following the Distribution Date and receipt by the Rights Agent
of all necessary information, the Rights Agent will keep or cause to be kept, at
its office designated as the appropriate place for surrender of Rights
Certificates upon exercise or transfer, books for registration and transfer of
the Rights Certificates issued hereunder. Such books shall show the

                                       8
<PAGE>

names and addresses of the respective holders of the Rights Certificates, the
number of Rights evidenced on its face by each of the Rights Certificates, the
Rights Certificate number and the date of each of the Rights Certificates.

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

            (a) Subject to the provisions of Section 11(a)(ii) and Section 14
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the Expiration Date, any Rights Certificate
or Certificates may be transferred, split up, combined or exchanged for another
Rights Certificate or Certificates, entitling the registered holder to purchase
a like number of shares of Common Stock (or, following a Triggering Event, other
securities, cash or other assets, as the case may be) as the Rights Certificate
or Certificates surrendered then entitled such holder (or former holder in the
case of a transfer) to purchase. Any registered holder desiring to transfer,
split up, combine or exchange any Rights Certificate or Certificates shall make
such request in writing delivered to the Rights Agent, and shall surrender the
Rights Certificate or Certificates to be transferred, split up, combined or
exchanged at the office of the Rights Agent designated for such purpose. Neither
the Rights Agent nor the Company shall be obligated to take any action
whatsoever with respect to the transfer of any such surrendered Rights
Certificate or Certificates until the registered holder shall have properly
completed and signed the certificate contained in the form of assignment set
forth on the reverse side of each such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company or
the Rights Agent shall reasonably request. Thereupon the Rights Agent shall,
subject to Section 14 hereof, countersign and deliver to the Person entitled
thereto a Rights Certificate or Certificates, as the case may be, 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 Rights Certificates. The Rights Agent shall
have no duty or obligation to take any action under any Section of this
Agreement which requires the payment by a Rights holder of applicable taxes and
governmental charges unless and until the Rights Agent is satisfied that all
such taxes and/or charges have been paid.

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

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

            (a) Except as otherwise provided herein, the registered holder of
any Rights Certificate may exercise the Rights evidenced thereby in whole or in
part at any time after the Distribution Date upon surrender of the Rights
Certificate, with the form of election to purchase

                                       9
<PAGE>

set forth on the reverse side thereof and the certificate contained therein
completed and duly executed, to the Rights Agent at the office of the Rights
Agent designated for such purpose, together with payment of the aggregate
Purchase Price with respect to the total number of shares of Common Stock (or
other securities, cash or other assets, as the case may be) as to which such
surrendered Rights are then exercisable, at or prior to the earlier of (i) the
Final Expiration Date, (ii) the time at which the Rights are redeemed as
provided in Section 23 hereof (the "Redemption Date"), or (iii) the time at
which such Rights are exchanged as provided in Section 24 hereof (the earliest
of (i), (ii) or (iii) being herein referred to as the "Expiration Date").

            (b) The Purchase Price for each share of Common Stock pursuant to
the exercise of a Right shall initially be the Initial Exercise Price, and shall
be subject to adjustment from time to time as provided in Sections 11 and 13(a)
hereof and shall be payable in accordance with paragraph (c) below.

            (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase set forth on the reverse side
thereof and the certificate contained therein completed and duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per share of Common Stock (or other securities, cash or other assets, as
the case may be) to be purchased as set forth below and an amount equal to any
applicable tax or charge, the Rights Agent shall, subject to Section 20(k)
hereof, promptly (i) requisition from any transfer agent of the shares of Common
Stock (or make available, if the Rights Agent is the transfer agent for such
shares) certificates for the total number of shares of Common Stock to be
purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, (ii) requisition from the Company the amount of
cash, if any, to be paid in lieu of fractional shares in accordance with Section
14 hereof, (iii) after receipt of such certificates, cause the same to be
delivered to or upon the order of the registered holder of such Rights
Certificate, registered in such name or names as may be designated by such
holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon
the order of the registered holder of such Rights Certificate. The payment of
the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)
hereof) shall be made in cash or by certified check, cashier's check or bank
draft payable to the order of the Company. In the event that, immediately prior
to the occurrence of a Distribution Date, the number of shares of Common Stock
which are authorized by the Company's Restated Certificate of Incorporation, as
amended and in effect at such time, but not outstanding or reserved for issuance
for purposes other than upon exercise of the Rights, is not sufficient to permit
exercise in full of the Rights in accordance with their terms, the Company,
acting by resolution of the Board, shall follow the same procedures and may take
any of the same actions in connection with the exercise of Rights under this
Section 7(c) as are required or permitted to be followed or taken pursuant to
Section 11(a)(iii) hereof with respect to substitution of value in connection
with the exercise of Rights under Section 11(a)(ii) hereof. The Company reserves
the right to require prior to the occurrence of a Triggering Event that, upon
any exercise of Rights, such number of Rights be exercised so that only whole
shares of Common Stock would be issued.

            (d) In case the registered holder of any Rights Certificate shall
exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing the Rights equivalent to the Rights remaining unexercised shall be
issued by the Rights Agent and delivered to, or

                                       10
<PAGE>

upon the order of, the registered holder of such Rights Certificate, registered
in such name or names as may be designated by such holder, subject to the
provisions of Section 14 hereof.

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

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

      Section 9. Reservation and Availability of Capital Stock.

            (a) The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares of Common
Stock (and, following the occurrence of a Triggering Event, other securities),
or out of its authorized and issued shares held in its treasury, the number of
shares of Common Stock (and, following the occurrence of a Triggering Event, the
amount of other securities) that, as provided in this Agreement including
Section 11(a)(iii) hereof, will be sufficient to permit the exercise in full of
all outstanding Rights.

            (b) So long as the shares of Common Stock (and, following the
occurrence of a Triggering Event, other securities) issuable and deliverable
upon the exercise of the Rights may be listed on any national securities
exchange, the Company shall use all reasonable efforts to cause all shares
reserved for such issuance to be listed on such exchange upon official notice of
issuance upon such exercise.

            (c) The Company shall use all reasonable efforts to (i) file, as
soon as practicable following the earliest date after the first occurrence of a
Triggering Event in which the consideration to be delivered by the Company upon
exercise of the Rights has been determined in accordance with this Agreement, a
registration statement under the Act, with respect to the Common Stock or other
securities purchasable upon exercise of the Rights on an appropriate form, (ii)
cause such registration statement to become effective as soon as practicable
after such filing, and (iii) cause such registration statement to remain
effective (with a prospectus at all times meeting the requirements of the Act)
until the earlier of (A) the date as of which the

                                       11
<PAGE>

Rights are no longer exercisable for such securities, and (B) the Expiration
Date. The Company will also take such action as may be appropriate under, or to
ensure compliance with, the securities or "blue sky" laws of the various states
in connection with the exercisability of the Rights. The Company may temporarily
suspend, for a period of time not to exceed ninety (90) days after the date set
forth in clause (i) of the first sentence of this Section 9(c), the
exercisability of the Rights in order to prepare and file such registration
statement and permit it to become effective. In addition, if the Company shall
determine that a registration statement is required following the Distribution
Date, the Company may temporarily suspend the exercisability of the Rights until
such time as a registration statement has been declared effective. Upon any
suspension of the exercisability of the Rights referred to in this Section 9(c),
the Company shall issue a public announcement stating that the exercisability of
the Rights has been temporarily suspended, as well as a public announcement at
such time as the suspension is no longer in effect. The Company shall promptly
provide the Rights Agent with copies of such announcements. Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable
and shall be void so long as held by a holder in any jurisdiction where the
requisite qualification to the issuance to such holder, or the exercise by such
holder, of the Rights in such jurisdiction shall not have been obtained or be
obtainable, the exercise thereof shall not be permitted under applicable law, or
a registration statement shall not have been declared effective.

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

            (e) The Company further covenants and agrees that, except as set
forth in Section 6(a) hereof and this Section 9(e), it will pay when due and
payable any and all taxes and governmental charges that may be payable in
respect of the issuance or delivery of the Rights Certificates and of any
certificates for a number of shares of Common Stock (or other securities, as the
case may be) upon the exercise of Rights. The Company shall not, however, be
required to pay any tax or charge that may be payable in respect of any transfer
or delivery of Rights Certificates to a Person other than, or the issuance or
delivery of a number of shares of Common Stock (or other securities, as the case
may be) in respect of a name other than that of, the registered holder of the
Rights Certificates evidencing Rights surrendered for exercise or to issue or
deliver any certificates for a number of shares of Common Stock (or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until such tax or charge shall have been
paid (any such tax or charge being payable by the holder of such Rights
Certificates at the time of surrender) or until it has been established to the
Company's satisfaction that no such tax or charge is due.

      Section 10. Record Date for Securities Issued Upon Exercise. Each Person
in whose name any certificate for a number of shares of Common Stock (or other
securities, as the case may be) is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of such Common Stock
(or other securities, as the case may be) represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all

                                       12
<PAGE>

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

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

            (a) (i) In the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the outstanding shares of Common Stock
payable in shares of Common Stock, (B) subdivide or split the outstanding shares
of Common Stock, (C) combine or consolidate the outstanding shares of Common
Stock into a smaller number of shares, or (D) issue any shares of its capital
stock in a reclassification of the Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), except as otherwise
provided in this Section 11(a) hereof, the Purchase Price in effect at the time
of the record date for such dividend or of the effective date of such
subdivision, split, combination, consolidation, or reclassification, and the
number and kind of shares of Common Stock or capital stock, as the case may be,
issuable on such date, shall be proportionately adjusted so that if a holder of
Rights after such time were to exercise that number of Rights (or fraction
thereof) which would result in the aggregate amount of the Purchase Price
payable upon such exercise (at the Purchase Price then in effect) being equal to
the amount of the Purchase Price payable prior to such time upon exercise of a
Right, such holder would be entitled to receive the aggregate number and kind of
shares of Common Stock or other capital stock, as the case may be, which, if a
Right had been exercised immediately prior to such time and at a time when the
Common Stock transfer books (or other capital stock transfer books, as the case
may be) of the Company were open, he would have owned upon such exercise and
been entitled to receive by virtue of such dividend, subdivision, split,
combination, consolidation 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) Subject to Section 24 of this Agreement, in the event any
Person becomes an Acquiring Person (the first occurrence of such event being
referred to hereinafter as the "Section 11(a)(ii) Event"), then (A) the Purchase
Price shall be adjusted to be the Purchase Price in effect immediately prior to
the Section 11(a)(ii) Event multiplied by the number of shares of Common Stock
for which a Right was exercisable immediately prior to such Section 11(a)(ii)
Event, whether or not such Right was then exercisable, and (B) each holder of a
Right, except as otherwise provided in this Section 11(a)(ii) and Section
11(a)(iii) hereof, shall

                                       13
<PAGE>

thereafter have the right to receive, upon exercise thereof at a price equal to
the Purchase Price (as so adjusted), in accordance with the terms of this
Agreement, such number of shares of Common Stock as shall equal the result
obtained by dividing the Purchase Price (as so adjusted) by 50% of the Current
Market Price per share of the Common Stock (determined pursuant to Section 11(d)
hereof) on the date of such Section 11(a)(ii) Event; provided, however, that the
Purchase Price (as so adjusted) and the number of shares of Common Stock so
receivable upon exercise of a Right shall, following the Section 11(a)(ii)
Event, be subject to further adjustment as appropriate in accordance with
Section 11(f) hereof. Notwithstanding anything in this Agreement to the
contrary, however, from and after the Section 11(a)(ii) Event, any Rights that
are beneficially owned by (x) any Acquiring Person (or any Affiliate or
Associate of any Acquiring Person), (y) a transferee of any Acquiring Person (or
any such Affiliate or Associate) who becomes a transferee after the Section
11(a)(ii) Event or (z) a transferee of any Acquiring Person (or any such
Affiliate or Associate) who became a transferee prior to or concurrently with
the Section 11(a)(ii) Event pursuant to either (I) a transfer from the Acquiring
Person to holders of its equity securities or to any Person with whom it has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (II) a transfer which the Board of Directors has determined is part of
a plan, arrangement or understanding which has the purpose or effect of avoiding
the provisions of this paragraph, and subsequent transferees of such Persons,
shall be void without any further action and any holder of such Rights shall
thereafter have no rights whatsoever with respect to such Rights under any
provision of this Agreement. The Company shall use all reasonable efforts to
ensure that the provisions of this Section 11(a)(ii) are complied with, but
shall have no liability to any holder of Right Certificates or other Person as a
result of its failure to make any determinations with respect to an Acquiring
Person or its Affiliates, Associates or transferees hereunder. From and after
the Section 11(a)(ii) Event, no Right Certificate shall be issued pursuant to
Section 3 or Section 6 hereof that represents Rights that are or have become
void pursuant to the provisions of this paragraph, and any Right Certificate
delivered to the Rights Agent that represents Rights that are or have become
void pursuant to the provisions of this paragraph shall be canceled. From and
after the occurrence of an event specified in Section 13(a) hereof, any Rights
that theretofore have not been exercised pursuant to this Section 11(a)(ii)
shall thereafter be exercisable only in accordance with Section 13 and not
pursuant to this Section 11(a)(ii).

                  (iii) In the event that the number of shares of Common Stock
which are authorized by the Company's Restated Certificate of Incorporation, as
amended, but not outstanding or reserved for issuance for purposes other than
upon exercise of the Rights are not sufficient to permit the exercise in full of
the Rights in accordance with the foregoing subparagraph (ii) of this Section
11(a), the Company shall (A) determine the value of the shares of Common Stock
issuable upon the exercise of a Right (the "Current Value"), and (B) with
respect to each Right, (subject to Section 11(a)(ii)) make adequate provision to
substitute, upon the exercise of a Right and payment of the applicable Purchase
Price, (1) cash, (2) a reduction in the Purchase Price (but in no event shall
the Purchase Price be less than the par value per share), (3) equity securities,
if any, of the Company other than Common Stock (including, without limitation,
shares, or units of shares, which the Board has deemed to have the same value as
shares of Common Stock (such shares being referred to herein as "Common Stock
Equivalents")), (4) debt securities of the Company, (5) other assets, or (6) any
combination of the foregoing, having an aggregate value equal to the Current
Value, as adjusted (less the amount of any reduction in the Purchase Price),
where such aggregate value has been determined by the

                                       14
<PAGE>

Board based upon the advice of a nationally recognized investment banking firm
selected by the Board; provided, however, if the Company shall not have made
adequate provision to deliver value pursuant to clause (B) above within thirty
(30) days following the first occurrence of a Section 11(a)(ii) Event (the
"Section 11(a)(ii) Trigger Date"), then the Company shall be obligated to
deliver, upon the surrender for exercise of a Right and without requiring
payment of the Purchase Price, shares of Common Stock (to the extent available)
and then, if necessary, cash, which shares or cash have an aggregate value equal
to the Spread. For purposes of the preceding sentence, the term "Spread" shall
mean the excess of (i) the Current Value over (ii) the Purchase Price. If the
number of shares of Common Stock that are authorized by the Company's Restated
Certificate of Incorporation, as amended, but not outstanding or reserved for
issuance for purposes other than upon exercise of the Rights, are not sufficient
to permit the exercise in full of any Rights and the Board determines in good
faith that it is likely that sufficient additional shares of Common Stock could
be authorized for issuance upon exercise in full of the Rights, the thirty (30)
day period set forth above may be extended to the extent necessary, but not more
than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that
the Company may seek stockholder approval for the authorization of such
additional shares (such thirty (30) day period, as it may be extended, shall be
referred to as the "Substitution Period"). To the extent that the Company
determines that some action need be taken pursuant to the preceding provisions
of this Section 11(a)(iii), the Company (x) shall provide, subject to Section
11(a)(ii) hereof, that such action shall apply uniformly to all outstanding
Rights, and (y) may suspend the exercisability of the Rights until the
expiration of the Substitution Period in order to seek any authorization of
additional shares or to decide the appropriate form of distribution to be made
pursuant to such provisions and to determine the value thereof. In the event of
any such suspension, the Company shall issue a public announcement stating that
the exercisability of the Rights has been temporarily suspended, as well as a
public announcement at such time as the suspension is no longer in effect and
the Company shall promptly provide the Rights Agent copies of such
announcements. For purposes of this Section 11(a)(iii), the value of each share
of Common Stock shall be the Current Market Price per share of the Common Stock
(as determined pursuant to Section 11(d) hereof) on the Section 11(a)(ii)
Trigger Date and the per share or per unit value of any Common Stock Equivalent
shall be deemed to equal the Current Market Price per share of the Common Stock
on such date.

            (b) In case the Company shall fix a record date for the issuance of
rights (other than the Rights), options or warrants to all holders of Common
Stock entitling them to subscribe for or purchase (for a period expiring within
forty-five (45) calendar days after such record date) Common Stock or securities
convertible into Common Stock or Common Stock Equivalents at a price per share
of Common Stock or per share of Common Stock Equivalents, (or having a
conversion price per share, if a security convertible into Common Stock) less
than the Current Market Price per share of Common Stock (as determined pursuant
to Section 11(d) hereof) on such record date except as otherwise provided in
Section 11(a) hereof, the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the sum
of (i) Common Stock or Common Stock Equivalents outstanding on such record date,
(ii) the number of shares of Common Stock or Common Stock Equivalents underlying
securities outstanding on such record date which are convertible into Common
Stock or Common Stock Equivalents and (iii) the number of shares of Common Stock
which the aggregate subscription price of the total number of shares of Common
Stock or Common Stock Equivalents so to be

                                       15
<PAGE>

offered (or the aggregate initial conversion price of the convertible securities
so to be offered) would purchase at such Current Market Price, and the
denominator of which shall be the sum of (i) the number of shares of Common
Stock outstanding on such record date, (ii) the number of shares of Common Stock
or Common Stock Equivalents underlying securities outstanding on such record
date which are convertible into Common Stock or Common Stock Equivalents and
(iii) the number of additional shares of Common Stock or Common Stock
Equivalents to be offered for subscription or purchase (or into which the
convertible securities so to be offered are initially convertible). In case such
subscription price may be paid by delivery of consideration part or all of which
may be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board, which determination shall be described in
a statement filed with the Rights Agent and shall be conclusive for all
purposes. Shares of Common Stock owned by or held for the account of the Company
shall not be deemed outstanding for the purpose of any such computation. Such
adjustment shall be made successively whenever such a record date is fixed, and
in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

            (c) In case the Company shall fix a record date for a distribution
to all holders of Common Stock (including any such distribution made in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation) of evidences of indebtedness, cash (other than a
regular quarterly or other periodic cash dividend out of the earnings or
retained earnings of the Company), assets (other than a dividend payable in
Common Stock, but including any dividend payable in stock other than Common
Stock) or subscription rights or warrants (excluding those referred to in
Section 11(b) hereof), the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
Current Market Price per share of Common Stock (as determined pursuant to
Section 11(d) hereof) on such record date, less the fair market value (as
determined in good faith by the Board whose determination shall be described in
a statement filed with the Rights Agent and shall be binding on the Rights Agent
and the holders of the Rights) of the portion of the cash, assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to a share of Common Stock and the denominator of which shall be such
Current Market Price per share of Common Stock (as determined pursuant to
Section 11(d) hereof). Such adjustments shall be made successively whenever such
a record date is fixed, and in the event that such distribution is not so made,
the Purchase Price shall be adjusted to be the Purchase Price which would have
been in effect if such record date had not been fixed.

            (d) For the purpose of any computation hereunder, other than
computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily closing prices per share of such Common Stock for the thirty (30)
consecutive Trading Days immediately prior to but not including such date, and
for the purposes of computations made pursuant to Section 11(a)(iii) hereof, the
Current Market Price per share of Common Stock on any date shall be deemed to be
the average of the daily closing prices per share of such Common Stock for the
ten (10) consecutive Trading Days immediately following but not including such
date; provided, however, that in the event that the Current Market Price per
share of the Common Stock is determined during a period following the
announcement by the issuer of such Common Stock of

                                       16
<PAGE>

(A) any dividend or distribution on such Common Stock payable in shares of such
Common Stock or securities convertible into shares of such Common Stock (other
than Rights), or (B) any subdivision, combination, consolidation, reverse stock
split or reclassification of such Common Stock, and prior to the expiration of
the requisite thirty (30) Trading Day or ten (10) Trading Day period, as set
forth above, after the ex-dividend date for such dividend or distribution, or
the record date for such subdivision, combination or reclassification, then, and
in each such case, the Current Market Price shall be properly adjusted to take
into account ex-dividend trading. The closing price for each day shall be the
last sale price, regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed on, the principal national securities exchange on which the
shares of Common Stock are listed or admitted to trading or, if the shares of
Common Stock are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by Nasdaq
or such other system then in use, or, if on any such date the shares of Common
Stock are not quoted by any such organization, the average of the closing bid
and asked prices as furnished by a professional market maker making a market in
the Common Stock selected by the Board. If on any such date no market maker is
making a market in the Common Stock, the fair value of such shares on such date
as determined in good faith by the Board shall be used. The term "Trading Day"
shall mean a day on which the principal national securities exchange on which
the shares of Common Stock are listed or admitted to trading is open for the
transaction of business or, if the shares of Common Stock are not listed or
admitted to trading on any national securities exchange, a Business Day. If the
Common Stock is not publicly held or not so listed or traded, Current Market
Price per share shall mean the fair value per share as determined in good faith
by the Board whose determination shall be described in a statement filed with
the Rights Agent and shall be conclusive for all purposes.

            (e) Anything herein to the contrary notwithstanding, no adjustment
in the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least one percent (1%) in the Purchase Price;
provided, however, that any adjustments which by reason of this Section 11(e)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section 11 shall be made
to the nearest cent or to the nearest ten-thousandth of a share of Common Stock,
as the case may be. Notwithstanding the first sentence of this Section 11(e),
any adjustment required by this Section 11 shall be made no later than the
earlier of (i) three (3) years from the date of the transaction which mandates
such adjustment, or (ii) the Expiration Date.

            (f) If as a result of an adjustment made pursuant to Section
11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter exercised
shall become entitled to receive any shares of capital stock other than Common
Stock, thereafter the number of such other shares so receivable upon exercise of
any Right and the Purchase Price thereof shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Common Stock contained in Sections 11(a), (b),
(c), (e), (g), (h), (i), (j), (k) and (m) hereof, and the provisions of Sections
7, 9, 10, 13 and 14 hereof with respect to the Common Stock shall apply on like
terms to any such other shares.

                                       17
<PAGE>

            (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of shares of Common Stock
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) hereof, upon each adjustment of the Purchase Price as a result
of the calculations made in Sections 11(b) and (c) hereof, each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
shares of Common Stock obtained by (i) multiplying (x) the number of shares
covered by a Right immediately prior to this adjustment, by (y) the Purchase
Price in effect immediately prior to such adjustment of the Purchase Price, and
(ii) dividing the product so obtained by the Purchase Price in effect
immediately after such adjustment of the Purchase Price.

            (i) The Company may elect on or after the date of any adjustment of
the Purchase Price to adjust the number of Rights, in lieu of any adjustment in
the number of shares of Common Stock purchasable upon the exercise of a Right.
Each of the Rights outstanding after the adjustment in the number of Rights
shall be exercisable for the number of shares of Common Stock 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-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to adjustment of the Purchase Price
by the Purchase Price in effect immediately after adjustment of the Purchase
Price. The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made, and shall promptly
give the Rights Agent a copy of such announcement. The record date may be the
date on which the Purchase Price is adjusted or any day thereafter, but, if the
Rights Certificates have been issued, shall be at least ten (10) days later than
the date of the public announcement. If Rights 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 Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Rights Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment. Rights Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein (and may bear, at the option of the Company, the adjusted Purchase
Price) and shall be registered in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.

            (j) Irrespective of any adjustment or change in the Purchase Price
or the number of shares of Common Stock issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue
to express the Purchase Price per share and the number of shares which were
expressed in the initial Rights Certificates issued hereunder.

                                       18
<PAGE>

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

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

            (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment the Board shall determine to be
advisable in order that any (i) consolidation or subdivision of the Common
Stock, (ii) issuance wholly for cash of any shares of Common Stock at less than
the Current Market Price, (iii) issuance wholly for cash of any shares of Common
Stock or securities which by their terms are convertible into or exchangeable
for shares of Common Stock, (iv) stock dividends, or (v) issuance of rights,
options or warrants referred to in this Section 11, hereafter made by the
Company to holders of its Common Stock shall not be taxable to such
stockholders.

            (n) The Company covenants and agrees that it shall not, at any time
after a Section 11(a)(ii) Event, (i) consolidate with any other Person, (ii)
merge with or into any other Person, or (iii) sell or transfer (or permit any
Subsidiary to sell or transfer), in one transaction, or a series of related
transactions, 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
other Person or Persons (other than the Company or any of its Subsidiaries in
one or more transactions each of which complies with Section 11(o) hereof), if
(x) at the time of or immediately after such consolidation, merger or sale there
are any rights, warrants or other instruments or securities outstanding or
agreements in effect that would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights or (y) prior to,
simultaneously with or immediately after such consolidation, merger or sale, the
stockholders of the Person who constitutes, or would constitute, the "Principal
Party" for purposes of Section 13(a) hereof shall have received a distribution
of Rights previously owned by such Person or any of its Affiliates and
Associates.

            (o) The Company covenants and agrees that, after the earlier of the
Stock Acquisition Date or the Distribution Date, it will not, except as
permitted by Section 23, Section 24 or Section 27 hereof, take (or permit any
Subsidiary to take) any action if at the time such

                                       19
<PAGE>

action is taken it is reasonably foreseeable that such action will diminish
substantially or otherwise eliminate the benefits intended to be afforded by the
Rights.

      Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 or Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the computations and facts accounting for
such adjustment, (b) promptly file with the Rights Agent, and with each transfer
agent for the Common Stock, a copy of such certificate, and (c) mail a brief
summary thereof to each holder of a Rights Certificate (or, if prior to the
Distribution Date, to each holder of a certificate representing shares of Common
Stock) in accordance with Section 26 hereof. Notwithstanding the foregoing
sentence, the failure of the Company to prepare such certificate or statement or
make such filings of the Company to prepare such certificate or statement or
make such filings or mailings shall not affect the validity of, or the force or
effect of, the requirement for such adjustment. The Rights Agent shall be fully
protected in relying on any such certificate and on any adjustment therein
contained and shall have no duty with respect to and shall not be deemed to have
knowledge of any such adjustment unless and until it shall have received such
certificate.

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

            (a) In the event, directly or indirectly, at any time after a
Section 11(a)(ii) Event (i) the Company shall consolidate with or shall merge
into any other Person, (ii) any Person shall merge with and into the Company and
the Company shall be the continuing or surviving corporation of such merger and,
in connection with such merger, all or part of the Common Stock shall be changed
into or exchanged for stock or other securities of any other Person (or of the
Company) or cash or any other property, or (iii) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one or more transactions, assets or earning power aggregating 50%
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person (other than the Company or one or more
wholly-owned Subsidiaries of the Company); then upon the first occurrence of
such event, proper provision shall be made so that: (A) each holder of a Right
(other than Rights which have become void pursuant to Section 11(a)(ii) hereof)
shall thereafter have the right to receive, upon the exercise thereof at the
Purchase Price (as theretofore adjusted in accordance with Section 11(a)(ii)
hereof), in accordance with the terms of this Agreement and in lieu of shares of
Common Stock, such number of validly authorized and issued, fully paid,
non-assessable and freely tradable shares of Common Stock of the Principal Party
(as such term is hereinafter defined), not subject to any liens, encumbrances,
rights of first refusal or other adverse claims, as shall equal the result
obtained by dividing the Purchase Price (as theretofore adjusted in accordance
with Section 11(a)(ii) hereof) by 50% of the current per share market price of
the Common Stock of such Principal Party (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; provided, however, that the Purchase Price (as theretofore adjusted in
accordance with Section 11(a)(ii) hereof) and the number of shares of Common
Stock of such Principal Party so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(f)
hereof to reflect any events occurring in respect of the Common Stock of such
Principal Party after the occurrence of such consolidation, merger, sale or
transfer; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such Section 13

                                       20
<PAGE>

Event, all the obligations and duties of the Company pursuant to this Agreement;
(iii) the term "Company" shall thereafter be deemed to refer to such Principal
Party, it being specifically intended that the provisions of Section 11 hereof
shall apply only to such Principal Party following the first occurrence of a
Section 13 Event; (iv) such Principal Party shall take such steps (including,
but not limited to, the reservation of a sufficient number of shares of its
common stock) in connection with the consummation of any such transaction as may
be necessary to assure that the provisions hereof shall thereafter be
applicable, as nearly as reasonably may be, in relation to its shares of common
stock thereafter deliverable upon the exercise of the Rights; and (v) the
provisions of Section 11(a)(ii) hereof shall be of no effect following the first
occurrence of any Section 13 Event.

            (b) "Principal Party" shall mean

                  (i) in the case of any transaction described in clause (i) or
(ii) of the first sentence of Section 13(a) hereof, the Person that is the
issuer of any securities into which shares of Common Stock are converted in such
merger or consolidation, and if no securities are so issued, the Person that is
the other party to such merger or consolidation (or, if there is more than one
such Person, the Person the Common Stock of which has the greatest market
value), or if the other party to the merger does not survive the merger, the
Person that does survive the merger (including the Company, if it survives); and

                  (ii) in the case of any transaction described in clause (iii)
of the first sentence of Section 13(a) hereof, the Person that is the party
receiving the greatest portion of the assets or earning power transferred
pursuant to such transaction or transactions or, if each Person that is a party
to such transaction or transactions receives the same portion of the assets or
earning power so transferred or if the Person receiving the greatest portion of
the assets or earning power cannot be determined, whichever of such Persons is
the issuer of Common Stock having the greatest market value;

provided, however, that in any such case, (1) if the common stock of such Person
is not at such time and has not been continuously over the preceding twelve (12)
month period registered under Section 12 of the Exchange Act, and such Person is
a direct or indirect Subsidiary of another Person the common stock of which is
and has been so registered, "Principal Party" shall refer to such other Person;
(2) in case such Person is a Subsidiary, directly or indirectly, of more than
one Person, the common stock of two or more of which are and have been so
registered, "Principal Party" shall refer to whichever of such Persons is the
issuer of the common stock having the greatest aggregate market value and (3) if
the Common Stock of such Person is not and has not been registered and such
Person is owned, directly or indirectly, by a joint venture formed by two or
more Persons that are not owned, directly or indirectly, by the same Person, the
rules set forth in (1) and (2) above shall apply to each of the chains of
ownership having an interest in such joint venture as if such party were a
Subsidiary of both or all of such joint venturers, and the Principal Parties in
each such chain shall bear the obligations set forth in this Section 13 in the
same ratio as their direct or indirect interests in such Person bear to the
total of such interests.

            (c) The Company shall not consummate any such consolidation, merger,
sale or transfer unless the Principal Party shall have a sufficient number of
authorized shares of its

                                       21
<PAGE>

Common Stock which have not been issued or reserved for issuance to permit the
exercise in full of the Rights in accordance with this Section 13 and unless
prior thereto the Company and such Principal Party shall have executed and
delivered to the Rights Agent a supplemental agreement providing for the terms
set forth in paragraphs (a) and (b) of this Section 13 and further providing
that, as soon as practicable after the date of any Section 13 Event, the
Principal Party will:

                  (i) prepare and file a registration statement under the Act,
with respect to the Rights and the securities purchasable upon exercise of the
Rights on an appropriate form, and will use its best efforts to cause such
registration statement to (A) become effective as soon as practicable after such
filing and (B) remain effective (with a prospectus at all times meeting the
requirements of the Act) until the Expiration Date and to similarly comply with
applicable state securities laws;

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

                  (iii) use its best efforts to list or obtain quotation of (or
continue the listing or quotation of) the Rights and the securities purchasable
upon exercise of the Rights on a national securities exchange or by an automated
quotation services; and

                  (iv) use its best efforts to list or obtain waivers of any
rights of first refusal or preemptive rights in respect of the shares of Common
Stock of the Principal Party subject to purchase upon exercise of outstanding
Rights.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. In the event that a Section 13 Event
shall occur at any time after the occurrence of a Section 11(a)(ii) Event, the
Rights which have not theretofore been exercised shall thereafter become
exercisable in the manner described in Section 13(a) hereof.

      Section 14. Fractional Rights and Fractional Shares.

            (a) The Company shall not be required to issue fractions of Rights,
except prior to the Distribution Date as provided in Section 11(i) hereof, or to
distribute Rights Certificates that evidence fractional Rights. If the Company
determines not to issue fractional Rights, there shall be paid in lieu thereof
to the registered holders of the Rights Certificates with regard to which such
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right. For purposes of this
Section 14(a), the current market value of a whole Right shall be the closing
price of the Rights for the Trading Day immediately prior to the date on which
such fractional Rights would have been otherwise issuable. The closing price of
the Rights for any day shall be the last sale price, regular way, or, in case no
such sale takes place on such day, the average of the closing bid and asked
prices, regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed on the principal
national securities exchange on which the Rights are listed or admitted to
trading, or if the Rights are not listed or admitted to trading on any national
securities exchange, the last quoted price or, if not so quoted, the average

                                       22
<PAGE>

of the high bid and low asked prices in the over-the-counter market, as reported
by Nasdaq or such other system then in use or, if on any such date the Rights
are not quoted by any such organization, the average of the closing bid and
asked prices as furnished by a professional market maker making a market in the
Rights selected by the Board. If on any such date no such market maker is making
a market in the Rights the fair value of the Rights on such date as determined
in good faith by the Board shall be used.

            (b) The Company shall not be required to issue fractions of shares
of Common Stock upon exercise of the Rights or to distribute certificates that
evidence fractional shares of Common Stock. In lieu of fractional shares of
Common Stock, the Company may pay to the registered holders of Rights
Certificates, with regard to which such fractional shares of Common Stock would
otherwise be issuable, at the time such Rights are exercised as herein provided,
an amount in cash equal to the same fraction of the current market value of one
share of Common Stock. For purposes of this Section 14(b), the current market
value of one share of Common Stock shall be the closing price of one share of
Common Stock, or if unavailable, the appropriate alternative price (determined
pursuant to Section 11(d) hereof) on the Trading Day immediately prior to the
date of such exercise.

            (c) The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right, except as permitted by this Section 14.

            (d) Whenever a payment for fractional Rights or fractional shares is
to be made by the Rights Agent, the Company shall (i) promptly prepare and
deliver to the Rights Agent a certificate setting forth in reasonable detail the
facts related to such payment and the prices and/or formulas utilized in
calculating such payments, and (ii) provide sufficient monies to the Rights
Agent in the form of fully collected funds to make such payments. The Rights
Agent shall be fully protected in relying upon such a certificate and shall have
no duty with respect to, and shall not be deemed to have knowledge of, any
payment for fractional Rights or fractional shares under any Section of this
Agreement relating to the payment of fractional Rights or fractional shares
unless and until the Rights Agent shall have received such a certificate and
sufficient monies.

      Section 15. Rights of Action. All rights of action in respect of this
Agreement, other than rights of action vested in the Rights Agent in Section 18
hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock); and any registered holder of any Rights Certificate (or, prior to
the Distribution Date, of the Common Stock), without the consent of the Rights
Agent or of the holder of any other Rights Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in his own behalf and for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce, or otherwise act in respect of, his right to
exercise the Rights evidenced by such Rights Certificate in the manner provided
in such Rights Certificate and in this Agreement. Without limiting the foregoing
or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and shall be entitled to specific performance
of the obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.

                                       23
<PAGE>

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

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

            (b) after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office or offices of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper instrument of transfer and
with the appropriate forms of assignment and certificates duly completed and
fully executed;

            (c) subject to Section 6(a) and Section 7(e) hereof, the Company and
the Rights Agent may deem and treat the person in whose name a Rights
Certificate (or, prior to the Distribution Date, the associated Common Stock
certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or writing on the
Rights Certificates or the associated Common Stock certificate made by anyone
other than the Company or the Rights Agent) for all purposes whatsoever, and
neither the Company nor the Rights Agent, subject to the last sentence of
Section 11(a)(ii) hereof, shall be required to 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 or ruling 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, the Company must use its
reasonable efforts to have any such order, decree or ruling lifted or otherwise
overturned as soon as possible.

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

      Section 18. Concerning the Rights Agent.

            (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
disbursements and other disbursements incurred in the preparation, execution,
delivery, amendment and administration of this Agreement and the exercise and
performance of its duties hereunder. The Company also agrees to indemnify the
Rights Agent for, and to hold it harmless against, any loss, liability, damage,
judgment, fine, penalty, claim, demand, settlement, cost or expense, incurred
without gross negligence, bad faith or willful misconduct on the part of the
Rights Agent (each as determined by a final, non-appealable order, judgment,
decree or ruling of a court of competent jurisdiction) for any action taken,
suffered or omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including, without limitation, the costs and
expenses of defending against any claim of liability in the premises. The costs
and expenses incurred in enforcing this right of indemnification shall be paid
by the Company. The provisions of this Section 18 and Section 20 below shall
survive the termination of this Agreement, the exercise or expiration of the
Rights and the resignation or removal of the Rights Agent.

            (b) The Rights Agent shall be authorized and protected and shall
incur no liability for or in respect of any action taken, suffered or omitted by
it in connection with its acceptance and administration of this Agreement in
reliance upon any Rights Certificate or certificate for Common Stock 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. The Rights Agent shall not be deemed to have
knowledge of any event of which it was supposed to receive notice thereof
hereunder, and the Rights Agent shall be fully protected and shall incur no
liability for failing to take any action in connection therewith unless and
until it has received such notice in writing.

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

            (a) Any Person into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any Person
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any Person succeeding to the
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, however, that such Person would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at the
time such successor Rights Agent shall succeed to the agency created by this
Agreement, any of the Rights Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the counter-signature of a
predecessor Rights Agent and deliver such Rights Certificates so countersigned;
and in case at that time any of the Rights Certificates shall not have been
countersigned, any successor Rights Agent may countersign such Rights
Certificates either in the name of the predecessor or the name of the successor
Rights Agent; and in all such cases such Rights Certificates shall have the full
force provided in the Rights Certificates and in this Agreement.

                                       25
<PAGE>

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

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

            (a) The Rights Agent may consult with legal counsel (who may be
legal counsel for the Company), and the advice or opinion of such counsel shall
be full and complete authorization and protection to the Rights Agent, and the
Rights Agent shall incur no liability for or in respect of, any action taken,
suffered or omitted by it 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
(including, without limitation, the identity of any Acquiring Person and the
determination of Current Market Price) be proved or established by the Company
prior to taking, suffering or omitting to take any action hereunder, such fact
or matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
certificate signed by the Chief Executive Officer and President, the Chief
Financial Officer, any Vice President, the Treasurer, any Assistant Treasurer,
the Secretary or any Assistant Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization and protection to
the Rights Agent and the Rights Agent shall incur no liability for or in respect
of, any action taken, suffered or omitted to be taken by it under the provisions
of this Agreement in reliance upon such certificate.

            (c) The Rights Agent shall be liable hereunder only for its own
gross negligence, bad faith or willful misconduct (each as determined by a
final, non-appealable order, judgment, decree or ruling of a court of competent
jurisdiction). Anything to the contrary notwithstanding, in no event shall the
Rights Agent be liable for special, punitive, indirect, consequential or
incidental loss or damage of any kind whatsoever (including but not limited to
lost profits), even if the Rights Agent has been advised of the likelihood of
such loss or damage. Any liability of the Rights Agent under this Agreement will
be limited to the amount of fees paid by the Company to the Rights Agent.

            (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 Rights
Certificates or be required to verify the same (except as to its
countersignature on such Rights Certificates), but all such statements and
recitals are and shall be deemed to have been made by the Company only.

                                       26
<PAGE>

            (e) The Rights Agent shall not be under any responsibility or have
any liability in respect of the validity of this Agreement or the execution and
delivery hereof (except the due execution hereof by the Rights Agent) or in
respect of the validity or execution of any Rights Certificate (except its
countersignature thereof); nor shall it be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any
Rights Certificate; nor shall it be responsible for any adjustment required
under the provisions of Section 11 or Section 13 hereof or responsible for the
manner, method or amount of any such adjustment or the ascertaining of the
existence of facts that would require any such adjustment (except with respect
to the exercise of Rights evidenced by Rights Certificates after receipt of a
certificate describing any such adjustment furnished in accordance with Section
12); nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Common Stock to
be issued pursuant to this Agreement or any Rights Certificate or as to whether
any shares of Common Stock will, when so 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 the
Chief Executive Officer and President, the Chief Financial Officer, any Vice
President, the Secretary, any Assistant Secretary, the Treasurer or any
Assistant Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and such instructions shall be full
authorization and protection to the Rights Agent and the Rights Agent shall
incur no liability for or in respect of any action taken, suffered or omitted to
be taken by it in accordance with instructions of any such officer.

            (h) The Rights Agent and any stockholder, affiliate, director,
officer or employee of the Rights Agent may buy, sell or deal in any of the
Rights or other securities of the Company or become pecuniarily interested in
any transaction in which the Company may be interested, or contract with or lend
money to the Company or otherwise act as fully and freely as though it were not
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 absent gross negligence, bad faith or willful misconduct
(each as determined by a final, non-appealable order, judgment, decree or ruling
of a court of competent jurisdiction) in the selection and continued employment
thereof.

            (j) No provision of this Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its

                                       27
<PAGE>

duties hereunder or in the exercise of its rights if it believes that repayment
of such funds or adequate indemnification against such risk or liability is not
assured to it.

            (k) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate contained in the form of
assignment or the form of election to purchase set forth on the reverse thereof,
as the case may be, has either not been completed or indicates an affirmative
response to clause 1 or 2 thereof, 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 thirty (30) days' notice in writing mailed to the Company, and to each
transfer agent of the Common Stock, by registered or certified mail, and to the
holders of the Rights Certificates by first-class mail. The Company may remove
the Rights Agent or any successor Rights Agent upon thirty (30) days' notice in
writing, mailed to the Rights Agent or successor Rights Agent, as the case may
be, and to each transfer agent of the Common Stock, by registered or certified
mail, and to the holders of the Rights Certificates by first-class mail. If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of thirty (30) days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by any registered holder of a Rights Certificate (who shall, with such notice,
submit his Rights Certificate for inspection by the Company), then any
registered holder of any Rights 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) a
Person organized and doing business under the laws of the United States or any
state thereof in good standing, which is authorized under such laws to exercise
stock transfer powers and is subject to supervision or examination by federal or
state authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $50,000,000 or (b) an affiliate of a
Person described in clause (a) of this sentence. After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the purpose. Not later than the effective date of any such appointment, the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Stock, and mail a notice thereof in
writing to the registered holders of the Rights Certificates. Failure to give
any notice provided for in this Section 21, however, or any defect therein,
shall not affect the legality or validity of the resignation or removal of the
Rights Agent or the appointment of the successor Rights Agent, as the case may
be.

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

                                       28
<PAGE>

provisions of this Agreement. In addition, in connection with the issuance or
sale of shares of Common Stock following the Distribution Date (other than upon
exercise of a Right) and prior to the redemption or expiration of the Rights,
the Company (a) shall, with respect to shares of Common Stock so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement, or upon the exercise, conversion or exchange of securities, notes,
warrants or debentures issued by the Company, and (b) may, in any other case, if
deemed necessary or appropriate by the Board, issue Rights Certificates
representing the appropriate number of Rights in connection with such issuance
or sale; provided, however, that (i) no such Rights Certificate shall be issued
if, and to the extent that, the Company shall be advised by counsel that such
issuance would create a significant risk of material adverse tax consequences to
the Company or the Person to whom such Rights Certificate would be issued, and
(ii) no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

      Section 23. Redemption and Termination.

            (a) The Board may, at its option, at any time prior to a Section
11(a)(ii) Event, redeem all but not less than all of the then outstanding Rights
at a redemption price of $0.001 per Right, as such amount may be appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price" ). The redemption of the Rights may be
made effective at such time, on such basis and with such conditions as the Board
in its sole discretion may establish.

            (b) The Company may, at its option, pay the Redemption Price in
cash, shares of Common Stock (based on the Current Market Price as defined in
Section 11(d) hereof, of the Common Stock at the time of redemption) or any
other form of consideration deemed appropriate by the Board.

            (c) Immediately upon the action of the Board ordering the redemption
of the Rights, and without any further action and without any notice, the right
to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the Redemption Price for each Right so
held. Promptly after the action of the Board ordering the redemption of the
Rights, the Company shall give notice of such redemption to the Rights Agent in
writing and the holders of the then outstanding Rights by mailing such notice to
all such holders at each holder's last address as it appears upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the Transfer Agent for the Common Stock. Any notice which is mailed in
the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of the redemption will state the method by
which the payment of the Redemption Price will be made.

      Section 24. Exchange.

            (a) At any time after a Section 11(a)(ii) Event, the Board may, at
its option, exchange all or part of the then outstanding and exercisable Rights
(which (i) shall not include Rights that have become null and void pursuant to
Section 11(a)(ii) hereof and (ii) shall include, without limitation, any Rights
issued after the Distribution Date in connection with the exercise

                                       29
<PAGE>

of options pursuant to any employee benefit plan or stock option plan of the
Company or any Subsidiary of the Company) for shares of Common Stock at an
exchange ratio of one share of Common Stock per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such exchange ratio being hereinafter referred to as the
"Exchange Ratio"). Notwithstanding the foregoing, the Board shall not be
empowered to effect such exchange at any time after any Person (other than the
Company, any of its Subsidiaries, any employee benefit plan or stock option plan
of the Company or any of its Subsidiaries or any Person organized, appointed or
established by the Company or any of its Subsidiaries for or pursuant to the
terms of any such plan), together with all Affiliates and Associates of such
Person, becomes the Beneficial Owner of 50% or more of the shares of Common
Stock then outstanding. From and after the occurrence of a Section 13 Event, any
Rights that theretofore have not been exchanged pursuant to this Section 24(a)
shall thereafter be exercised only in accordance with Section 13 and may not be
exchanged pursuant to this Section 24(a).

            (b) Immediately upon the action of the Board electing to exchange
any Rights pursuant to Section 24(a) and without any further action and without
any notice, the right to exercise such Rights will terminate and thereafter the
only right of the holders of such Rights shall be to receive that number of
shares of Common Stock equal to the number of such Rights held by such holder
multiplied by the Exchange Ratio. The Company shall promptly thereafter give
written notice of such exchange to the Rights Agent and the holders of the
Rights to be exchanged in the manner set forth in Section 26; provided, however,
that the failure to give, or any defect in, such notice shall not affect the
validity of such exchange. Any notice which is mailed in the manner herein
provided shall be deemed given, whether or not the holder receives the notice.
Each such notice of exchange will state the method by which the exchange of the
shares of Common Stock for Rights will be effected and, in the event of any
partial exchange, the number of Rights which will be exchanged. Any partial
exchange shall be effected pro rata based on the number of Rights (other than
Rights which have become void pursuant to Section 11(a)(ii)) held by each holder
of Rights.

            (c) In any exchange pursuant to this Section 24, the Company, at its
option, may substitute Common Stock Equivalents (as defined in Section
11(a)(iii)) for shares of Common Stock exchangeable for Rights, at the initial
rate of one Common Stock Equivalent for each share of Common Stock, as
appropriately adjusted to reflect adjustments in dividend, liquidation and
voting rights of Common Stock Equivalents pursuant to the terms thereof, so that
each Common Stock Equivalent delivered in lieu of each share of Common Stock
shall have essentially the same dividend, liquidation and voting rights as one
share of Common Stock.

            (d) In the event that the number of shares of Common Stock which are
authorized by the Company's Restated Certificate of Incorporation, as amended,
but not outstanding or reserved for issuance are not sufficient to permit an
exchange of Rights as contemplated by this Section 24, the Company shall take
all such action as may be necessary to authorize additional shares of Common
Stock for issuance upon exchange of the Rights.

            (e) The Company shall not be required to issue fractions of shares
of Common Stock or to distribute certificates that evidence fractional shares of
Common Stock. In lieu of fractional shares of Common Stock, the Company may pay
to the registered holders of

                                       30
<PAGE>

Rights Certificates with regard to which such fractional shares of Common Stock
would otherwise be issuable, an amount in cash equal to the same fraction of the
current market value of a whole share of Common Stock. For purposes of this
Section 24(e), the current market value of a whole share of Common Stock shall
be the closing price per share of Common Stock (determined pursuant to Section
11(d)(ii) hereof) on the Trading Day immediately prior to the date of exchange
pursuant to this Section 24.

      Section 25. Notice of Certain Events.

            (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Common Stock or to make any other distribution to the holders of
Common Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), or (ii) to offer to the holders of Common
Stock rights or warrants to subscribe for or to purchase any additional shares
of Common Stock or shares of stock of any class or any other securities, rights
or options, or (iii) to effect any reclassification of its Common Stock (other
than a reclassification involving only the subdivision of outstanding shares of
Common Stock), or (iv) to effect any consolidation or merger into or with any
other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), 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 transaction or a series of related transactions, of more than 50% of the
assets or earning power of the Company and its Subsidiaries (taken as a whole)
to any other Person or Persons (other than the Company or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of
the Company, then, in each such case, the Company shall give to each holder of a
Rights Certificate, to the extent feasible, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend or distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the shares of Common Stock, 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 twenty (20) days prior to
the record date for determining holders of the shares of Common Stock for
purposes of such action, and in the case of any such other action, at least
twenty (20) days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of the shares of Common Stock,
whichever shall be the earlier.

            (b) In case any Section 11(a)(ii) Event or Section 13 Event shall
occur, then, in any such case, (i) the Company shall as soon as practicable
thereafter give to each holder of a Rights Certificate and to the Rights Agent,
and in accordance with Section 26 hereof, a notice of the occurrence of such
event, which shall specify the event and the consequences of the event to
holders of Rights under Section 11(a)(ii) or Section 13 hereof and (ii) all
references in the preceding paragraph to Common Stock shall, to the extent
appropriate, also be deemed thereafter to refer to other securities.

      Section 26. Notices. Notices or demands authorized by this Agreement to be
given or made by the Rights Agent or by the holder of any Rights Certificate to
or on the Company shall

                                       31

            Waltham, MA 02451
            Attention: Chief Executive Officer and President

Subject to the provisions of Section 21, any notice or demand authorized by this
Agreement to be given or made by the Company or by the holder of any Rights
Certificate to or on the Rights Agent shall be sufficiently given or made if

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

      Section 27. Supplements and Amendments. Except as provided in the
penultimate sentence of this Section 27, for so long as the Rights are then
redeemable, the Company may in its sole and absolute discretion, and the Rights
Agent shall if the Company so directs, supplement or amend any provision of this
Agreement in any respect without the approval of any holders of the Rights. At
any time when the Rights are no longer redeemable, except as provided in the
penultimate sentence of this Section 27, the Company may, and the Rights Agent
shall, if the Company so directs, supplement or amend this Agreement without the
approval of any holders of Rights; provided that no such supplement or amendment
may (a) adversely affect the interests of the holders of Rights as such (other
than an Acquiring Person or an Affiliate or Associate of an Acquiring Person),
(b) cause this Agreement again to become amendable other than in accordance with
this sentence or (c) cause the Rights again to become redeemable.
Notwithstanding anything contained in this Agreement to the contrary, no
supplement or amendment shall be made which changes the Redemption Price. Upon
the delivery of a certificate from an appropriate officer of the Company which
states that the supplement or amendment is in compliance with the terms of this
Section 27, the Rights Agent shall execute such supplement or amendment;
provided that any supplement or amendment that does not amend Sections 18, 19,
20 or 21 hereof in a manner adverse to the Rights Agent shall become effective
immediately upon execution by the Company, whether or not also executed by the
Rights Agent.

                                       32

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

      Section 29. Determinations and Actions by the Board of Directors, etc. The
Board shall have the exclusive power and authority to administer this Agreement
and to exercise all rights and powers specifically granted to the Board or to
the Company, or as may be necessary or advisable in the administration of this
Agreement, including, without limitation, the right and power to (i) interpret
the provisions of this Agreement, and (ii) make all determinations deemed
necessary or advisable for the administration of this Agreement (including a
determination to redeem or not redeem the Rights or to amend the Agreement). All
such actions, calculations, interpretations and determinations which are done or
made by the Board in good faith, shall be final, conclusive and binding on the
Company, the Rights Agent, the holders of the Rights and all other Persons.

      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 Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock) any legal or equitable right,
remedy or claim under this Agreement; but this Agreement shall be for the sole
and exclusive benefit of the Company, the Rights Agent and the registered
holders of the Rights Certificates (and, prior to the Distribution Date,
registered holders of the Common Stock).

      Section 31. Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions of this Agreement shall remain in full
force and effect and shall in no way be affected, impaired or invalidated.

      Section 32. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be deemed to be a contract made under the
internal laws of the State of Delaware and for all purposes shall be governed by
and construed in accordance with the laws of such State applicable to contracts
made and to be performed entirely within such State; provided, however, that all
provisions regarding the rights, duties and obligations of the Rights Agent
shall be governed by and construed in accordance with the laws of The
Commonwealth of Massachusetts applicable to contracts made and to be performed
entirely within such State.

      Section 33. Counterparts. This Agreement may be executed in any number of
counterparts and each of such counterparts shall for all purposes be deemed to
be an original, and all such counterparts shall together constitute but one and
the same instrument.

                   SUMMARY OF RIGHTS TO PURCHASE COMMON STOCK

      On March 24, 2005 the Board of Directors of OXiGENE, INC. (the "Company")
declared a dividend of one common stock purchase right (a "Right") for each
outstanding share of the Company's voting common stock, $.01 par value (the
"Common Stock"), to stockholders of record at the close of business on April 4,
2005 (the "Record Date"). Each Right entitles the registered holder to purchase
from the Company one share of Common Stock, at a purchase price of $50.00 in
cash (the "Purchase Price"), subject to adjustment. The description and terms of
the Rights are set forth in a Stockholder Rights Agreement (the "Rights
Agreement") between the Company and American Stock Transfer & Trust Company, as
Rights Agent.

      Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate certificates for Rights
will be distributed. The Rights will separate from the Common Stock and a
"Distribution Date" will occur upon the earlier of (i) 10 days following a
public announcement that a person or group of affiliated or associated persons
(an "Acquiring Person") has acquired, or obtained the right to acquire,
beneficial ownership of 15% or more of the outstanding shares of the Company's
Common Stock (the "Stock Acquisition Date") or (ii) 10 business days following
the commencement of a tender offer or exchange offer that may result in a person
or group beneficially owning 15% or more of the outstanding shares of the
Company's Common Stock.

      Until the Distribution Date (or earlier redemption or expiration of the
Rights), (i) the Rights will be evidenced by the Common Stock certificates and
will be transferred with and only with such Common Stock certificates, (ii) new
Common Stock certificates issued after the Record Date will contain a notation
incorporating the Rights Agreement by reference, and (iii) the surrender for
transfer of any certificates for Common Stock outstanding, even without such
notation, will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate.

      The Rights are not exercisable until the Distribution Date and will expire
at the close of business on March 24, 2015, unless earlier redeemed or exchanged
by the Company as described below.

      As soon as practicable after the Distribution Date, separate certificates
evidencing the Rights ("Rights Certificates") will be mailed to holders of
record of the Common Stock as of the close of business on the Distribution Date
(other than to any Acquiring Person or any associate or affiliate of an
Acquiring Person), and thereafter such separate Rights Certificates alone will
represent the Rights. Except as otherwise determined by the Board and except in
connection with shares of Common Stock issued after the Distribution Date upon
the exercise of employee stock options, under other employee stock benefit
plans, or upon the conversion of convertible securities, only shares of Common
Stock issued prior to the Distribution Date will be issued with Rights.

      In the event any Person becomes an Acquiring Person, also known as a
"Section 11(a)(ii) Event", each holder of a Right will thereafter have the right
to receive, upon exercise, that

<PAGE>

number of shares of Common Stock (or, in certain circumstances, cash, property
or other securities of the Company) which equals the exercise price of the Right
divided by one-half of the current market price (as defined in the Rights
Agreement) of the Common Stock at the date of the occurrence of the event.
Notwithstanding any of the foregoing, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by an
Acquiring Person will be null and void.

      In the event that, at any time following a Section 11(a)(ii) Event, (i)
the Company is acquired in a merger or other business combination transaction or
(ii) more than 50% of the Company's assets or earning power is sold or
transferred, each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, that number of shares of common stock of the acquiring company which
equals the exercise price of the Right divided by one-half of the current market
price (as defined in the Rights Agreement) of such common stock at the date of
the occurrence of the event. The events set forth in this paragraph and in the
preceding paragraph are referred to as the "Triggering Events."

      At any time after the occurrence of a Section 11(a)(ii) Event, the Board
may exchange the Rights (other than Rights owned by an Acquiring Person which
have become void), in whole or in part, at an exchange ratio of one share of
Common Stock, or one Common Stock Equivalent (as defined in the Rights
Agreement), per Right (subject to adjustment).

      The Purchase Price payable, and the number of shares of Common Stock or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Common
Stock, (ii) if holders of the Common Stock are granted certain rights or
warrants to subscribe for Common Stock or convertible securities at less than
the current market price of the Common Stock, or (iii) upon the distribution to
holders of the Common Stock of evidences of indebtedness or assets (excluding
regular quarterly cash dividends) or of subscription rights or warrants (other
than those referred to above).

      With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. No fractional shares of Common Stock will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the Common Stock
on the last trading date prior to the date of exercise.

      In general, the Company may redeem the Rights in whole, but not in part,
at any time before a Section 11(a)(ii) Event, at a price of $.001 per Right
(payable in cash, Common Stock or other consideration deemed appropriate by the
Board). Immediately upon the action of the Board ordering redemption of the
Rights, the Rights will terminate and the only right of the holders of Rights
will be to receive the $.001 per Right redemption price. The redemption price is
payable in cash, stock or other consideration deemed appropriate by the Board.

      Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights

                                       2
<PAGE>

become exercisable for Common Stock (or other consideration) of the Company or
for common stock of the acquiring company as set forth above.

      Subject to certain exceptions, any of the provisions of the Rights
Agreement may be amended by the Board of Directors of the Company prior to such
time as the Rights are no longer redeemable.

      A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an exhibit to the Company's Current Report on Form 8-K,
dated March 24, 2005 and filed on March 30, 2005. A copy of the Rights Agreement
is available free of charge from the Company. This summary description of the
Rights does not purport to be complete and is qualified in its entirety by
reference to the Rights Agreement, which is incorporated herein by reference.

COMPANY. THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE COMPANY, AT
$0.001 PER RIGHT, ON THE TERMS SET FORTH IN THE RIGHTS AGREEMENT. UNDER CERTAIN
CIRCUMSTANCES, RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON OR AN AFFILIATE

AGREEMENT) AND ANY SUBSEQUENT HOLDER OF SUCH RIGHTS WILL BECOME NULL AND VOID.

                               Rights Certificate

                                  OXiGENE, INC.

      This Rights Certificate certifies that ____________________, or registered
assigns, is the registered holder of the number of Rights set forth above, each
of which entitles the holder thereof, subject to the terms, provisions and
conditions of the Stockholder Rights Agreement, dated as of March 24, 2005 (the
"Rights Agreement"), between OXiGENE, Inc., a Delaware corporation (the
"Company"), and American Stock Transfer & Trust Company (the "Rights Agent"), to
purchase from the Company after the Distribution Date (as such term is defined
in the Rights Agreement) and at any time prior to the Expiration Date (as such
term is defined in the Rights Agreement) at the office or offices of the Rights
Agent designated for such purpose, or its successors as Rights Agent, one fully
paid, non-assessable share of Common Stock, $.01 par value per share (the
"Common Stock") of the Company, at a purchase price of $50.00 per share (the
"Purchase Price"), upon presentation and surrender of this Rights Certificate
with the Form of Election to Purchase and related Certificate duly executed. The
number of Rights evidenced by this Rights Certificate (and the number of shares
which may be purchased upon exercise thereof) set forth above, and the Purchase
Price per share set forth above, are the number and Purchase Price as of
______________, based on the Common Stock as constituted at such date. The
Company reserves the right to require prior to the occurrence of a Triggering
Event (as such term is defined in the Rights Agreement) that a number of Rights
be exercised so that only whole shares of Common Stock will be issued.

      Capitalized terms used herein and not otherwise defined herein shall have
the meanings assigned to such terms in the Rights Agreement.

      Upon the occurrence of a Section 11(a)(ii) Event, if the Rights evidenced
by this Rights Certificate are beneficially owned by (i) an Acquiring Person or
an Affiliate or Associate of an Acquiring Person (ii) a transferee of an
Acquiring Person (or of any such Associate or Affiliate of an Acquiring Person),
or (iii) under certain circumstances specified in the Rights Agreement, a

<PAGE>

transferee of a person who, after such transfer, became an Acquiring Person (or
an Associate or Affiliate of an Acquiring Person), such Rights shall become null
and void and no holder hereof shall have any right with respect to such Rights
from and after the occurrence of such Section 11(a)(ii) Event.

      As provided in the Rights Agreement, the Purchase Price and the number and
kind of shares of Common Stock or other securities which may be purchased upon
the exercise of the Rights evidenced by this Rights Certificate are subject to
modification and adjustment upon the happening of certain events, including
Triggering Events.

      This Rights 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, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the office of the Company and are
also available upon written request to the Company.

      This Rights Certificate, with or without other Rights Certificates, upon
surrender at the principal office or offices of the Rights Agent designated for
such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of shares of Common Stock as the Rights
evidenced by the Rights Certificate or Rights Certificates surrendered shall
have entitled such holder to purchase. If this Rights Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender hereof
another Rights Certificate or Rights Certificates for the number of whole Rights
not exercised.

      Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Certificate may be redeemed by the Company at the option of the Board at a
redemption price of $.001 per Right at any time prior to a Section 11(a)(ii)
Event.

      No fractional shares of Common Stock will be issued upon the exercise of
any Right or Rights evidenced hereby, but in lieu thereof a cash payment will be
made, as provided in the Rights Agreement.

      No holder of this Rights Certificate shall be entitled to vote or receive
dividends or be deemed for any purpose the holder of shares of Common Stock or
of any other securities of the Company which 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
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in the Rights
Agreement), or to receive dividends or subscription rights, or otherwise, until
the Right or Rights evidenced by this Rights Certificate shall have been
exercised as provided in the Rights Agreement.

("Effective Date") of the registration statement ("Registration Statement")
pursuant to which Units are offered for sale to the public ("Offering"). Each
Warrant is exercisable at $5.00 per share (as adjusted from time to time) and is
the same as the warrants included in the Units being registered for sale to the

which banking institutions are authorized by law to close, then this Purchase
Option may be exercised on the next succeeding day which is not such a day in
accordance with the terms herein. During the period ending on the Expiration
Date, the Company agrees not to take any action that would

terminate the Purchase Option. This Purchase Option is initially exercisable at
$7.50 per Unit so purchased; provided, however, that upon the occurrence of any
of the events specified in Section 6 hereof, the rights granted by this Purchase
Option, including the exercise price per Unit and the number of Units (and

adjusted as therein specified. The term "Exercise Price" shall mean the initial
exercise price or the adjusted exercise price, depending on the context.

2.       Exercise.

exercise form attached hereto must be duly executed and completed and delivered
to the Company, together with this Purchase Option and payment of the Exercise
Price for the Units being purchased payable in cash or by certified check or
official bank check. If the subscription rights represented hereby shall not be
exercised at or before 5:00 p.m., Eastern time, on the Expiration Date this
Purchase Option shall become and be void without further force or effect, and
all rights represented hereby shall cease and expire.

         2.2      Legend. Each certificate for the securities purchased under
this Purchase Option shall bear a legend as follows unless such securities have
been registered under the Securities Act of 1933, as amended ("Act"):

                  "The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act") or applicable state law. The securities may not be
                  offered for sale, sold or otherwise transferred except
                  pursuant to an effective registration statement under the Act,
                  or pursuant to an exemption from registration under the Act
                  and applicable state law."

         2.3      Cashless Exercise.

                  In lieu of the payment of the Exercise Price multiplied by the
number of Units for which this Purchase Option is exercisable (and in lieu of
being entitled to receive Common Stock and Warrants) in the manner required by
Section 2.1, the Holder shall have the right (but not the obligation) to convert
any exercisable but unexercised portion of this Purchase Option into Units
("Conversion Right") as follows: upon exercise of the Conversion Right, the
Company shall deliver to the Holder (without payment by the Holder of any of the
Exercise Price in cash) that number of Units (or that number of shares of Common
Stock and Warrants (or that number of shares of comprising that number of Units)
equal to the quotient obtained by dividing (x) the "Value" (as defined below) of
the portion of the Purchase Option being converted by (y) the Current Market
Value (as defined below). The "Value" of the portion of the Purchase Option
being converted shall equal the remainder derived from subtracting (a) (i) the
Exercise Price multiplied by (ii) the number of Units underlying the portion of
this Purchase Option being converted from (b) the Current Market Value of a Unit
multiplied by the number of Units underlying the portion of the Purchase Option
being converted. As used herein, the term "Current Market Value" per Unit at any
date means: (A) in the event that neither the Units nor Warrants are still
trading, the remainder derived from subtracting (x) the exercise price of the
Warrants multiplied by the number of shares of Common Stock issuable upon
exercise of the Warrants underlying one Unit from (y) (i) the Current Market
Price of the Common Stock multiplied by (ii) the number of shares of Common
Stock underlying one Unit, which shall include the shares of Common Stock
underlying the Warrants included in such Unit; (B) in the event that the Units,
Common Stock and Warrants are still trading, (i) if the Units are listed on a
national securities exchange or quoted on the Nasdaq National Market, Nasdaq
SmallCap Market or NASD OTC Bulletin Board (or successor such as the Bulletin
Board Exchange), the last sale price of the Units in the principal trading
market for the Units as reported by the exchange, Nasdaq or the NASD, as the
case may be, on the last trading day preceding the date in question; or (ii) if
the Units are not listed on a national securities exchange or quoted on the
Nasdaq National Market, Nasdaq SmallCap Market or the NASD OTC Bulletin Board
(or successor exchange), but is traded in the residual over-the-counter market,

                                       2

the closing bid price for Units on the last trading day preceding the date in
question for which such quotations are reported by the Pink Sheets, LLC or
similar publisher of such quotations; and (C) in the event that the Units are
not still trading but the Common Stock and Warrants underlying the Units are
still trading, the Current Market Price of the Common Stock plus the product of
(x) the Current Market Price of the Warrants and (y) the number of shares of
Common Stock underlying the Warrants included in one Unit. The "Current Market
Price" shall mean (i) if the Common Stock (or Warrants, as the case may be) is
listed on a national securities exchange or quoted on the Nasdaq National
Market, Nasdaq SmallCap Market or NASD OTC Bulletin Board (or successor such as
the Bulletin Board Exchange), the last sale price of the Common Stock (or
Warrants) in the principal trading market for the Common Stock as reported by
the exchange, Nasdaq or the NASD, as the case may be, on the last trading day
preceding the date in question; (ii) if the Common Stock (or Warrants, as the
case may be) is not listed on a national securities exchange or quoted on the
Nasdaq National Market, Nasdaq SmallCap Market or the NASD OTC Bulletin Board
(or successor exchange), but is traded in the residual over-the-counter market,
the closing bid price for the Common Stock (or Warrants) on the last trading day
preceding the date in question for which such quotations are reported by the
Pink Sheets, LLC or similar publisher of such quotations; and (iii) if the fair
market value of the Common Stock cannot be determined pursuant to clause (i) or
(ii) above, such price as the Board of Directors of the Company shall determine,
in good faith.

                  2.3.2 Mechanics of Cashless Exercise. The Cashless Exercise
Right may be exercised by the Holder on any business day on or after the
Commencement Date and not later than the Expiration Date by delivering the
Purchase Option with the duly executed exercise form attached hereto with the
cashless exercise section completed to the Company, exercising the Cashless
Exercise Right and specifying the total number of Units the Holder will purchase
pursuant to such Cashless Exercise Right.

3.       Transfer.

         3.1      General Restrictions. The registered Holder of this Purchase
Option, by its acceptance hereof, agrees that it will not sell, transfer,
assign, pledge or hypothecate this Purchase Option for a period of one year
following the Effective Date to anyone other than (i) Sunrise or an underwriter
or a selected dealer in connection with the Offering, or (ii) a bona fide
officer or partner of Sunrise or of any such underwriter or selected dealer. On
and after the first anniversary of the Effective Date, transfers to others may
be made subject to compliance with or exemptions from applicable securities
laws. In order to make any permitted assignment, the Holder must deliver to the
Company the assignment form attached hereto duly executed and completed,
together with the Purchase Option and payment of all transfer taxes, if any,
payable in connection therewith. The Company shall within five business days
transfer this Purchase Option on the books of the Company and shall execute and
deliver a new Purchase Option or Purchase Options of like tenor to the
appropriate assignee(s) expressly evidencing the right to purchase the aggregate
number of Units purchasable hereunder or such portion of such number as shall be
contemplated by any such assignment.

         3.2      Restrictions Imposed by the Act. The securities evidenced by
this Purchase Option shall not be transferred unless and until (i) the Company
has received the opinion of counsel for the Holder that the securities may be
transferred pursuant to an exemption from registration under the Act and
applicable state securities laws, the availability of which is established to
the reasonable satisfaction of the Company (the Company hereby agreeing that the
opinion of Graubard Miller shall be deemed satisfactory evidence of the
availability of an exemption), or (ii) a registration statement or a
post-

                                       3

effective amendment to the Registration Statement relating to such securities
has been filed by the Company and declared effective by the Securities and
Exchange Commission and compliance with applicable state securities law has been
established.

4.        New Purchase Options to be Issued.

         4.1 Partial Exercise or Transfer. Subject to the restrictions in
Section 3 hereof, this Purchase Option may be exercised or assigned in whole or
in part. In the event of the exercise or assignment hereof in part only, upon
surrender of this Purchase Option for cancellation, together with the duly
executed exercise or assignment form and funds sufficient to pay any Exercise
Price and/or transfer tax, the Company shall cause to be delivered to the Holder
without charge a new Purchase Option of like tenor to this Purchase Option in
the name of the Holder evidencing the right of the Holder to purchase the number
of Units purchasable hereunder as to which this Purchase Option has not been
exercised or assigned.

         4.2 Lost Certificate. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Option and of reasonably satisfactory indemnification or the posting of
a bond, the Company shall execute and deliver a new Purchase Option of like
tenor and date. Any such new Purchase Option executed and delivered as a result
of such loss, theft, mutilation or destruction shall constitute a substitute
contractual obligation on the part of the Company.

5.       Registration Rights.

         5.1      Demand Registration.

                  5.1.1 Grant of Right. The Company, upon written demand
("Initial Demand Notice") of the Holder(s) of at least 51% of the Purchase
Options and/or the underlying Units and/or the underlying securities ("Majority
Holders"), agrees to register on one occasion, all or any portion of the
Purchase Options requested by the Majority Holders in the Initial Demand Notice
and all of the securities underlying such Purchase Options, including the Units,
Common Stock, the Warrants and the Common Stock underlying the Warrants
(collectively, the "Registrable Securities"). On such occasion, the Company will
file a registration statement or a post-effective amendment to the Registration
Statement covering the Registrable Securities within sixty days after receipt of
the Initial Demand Notice and use its best efforts to have such registration
statement or post-effective amendment declared effective as soon as possible
thereafter. The demand for registration may be made at any time during a period
of five years beginning on the Effective Date. The Company covenants and agrees
to give written notice of its receipt of any Initial Demand Notice by any
Holder(s) to all other registered Holders of the Purchase Options and/or the
Registrable Securities within ten days from the date of the receipt of any such
Initial Demand Notice.

                  5.1.2 Terms. The Company shall bear all fees and expenses
attendant to registering the Registrable Securities, including the expenses of
any legal counsel selected by the Holders to represent them in connection with
the sale of the Registrable Securities, but the Holders shall pay any and all
underwriting commissions. The Company agrees to use its reasonable best efforts
to qualify or register the Registrable Securities in such States as are
reasonably requested by the Majority Holder(s); provided, however, that in no
event shall the Company be required to register the Registrable Securities in a
State in which such registration would cause (i) the Company to be obligated to
qualify to do business in such State, or would subject the Company to taxation
as a foreign corporation doing business

                                       4

in such jurisdiction or (ii) the principal stockholders of the Company to be
obligated to escrow their shares of capital stock of the Company. The Company
shall cause any registration statement or post-effective amendment filed
pursuant to the demand rights granted under Section 5.1.1 to remain effective
for a period of nine consecutive months from the effective date of such
registration statement or post-effective amendment.

         5.2      "Piggy-Back" Registration.

                  5.2.1 Grant of Right. In addition to the demand right of
registration, the Holders of the Purchase Options shall have the right for a
period of seven years commencing on the Effective Date, to include the
Registrable Securities as part of any other registration of securities filed by
the Company (other than in connection with a transaction contemplated by Rule
145(a) promulgated under the Act or pursuant to Form S-8); provided, however,
that if, in the written opinion of the Company's managing underwriter or
underwriters, if any, for such offering, the inclusion of the Registrable
Securities, when added to the securities being registered by the Company or the
selling stockholder(s), will exceed the maximum amount of the Company's
securities ("Maximum Number of Shares") which can be marketed (i) at a price
reasonably related to their then current market value, and (ii) without
materially and adversely affecting the entire offering, then the Company shall
include in any such registration:

                             (i) If the registration is undertaken for the
Company's account: (A) first, the shares of Common Stock or other securities
that the Company desires to sell that can be sold without exceeding the Maximum
Number of Shares; (B) second, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clause (A), the shares of Common Stock,
if any, including the Registrable Securities, as to which registration has been
requested pursuant to written contractual piggy-back registration rights of
security holders (pro rata in accordance with the number of shares of Common
Stock which each such person has actually requested to be included in such
registration, regardless of the number of shares of Common Stock with respect to
which such persons have the right to request such inclusion) that can be sold
without exceeding the Maximum Number of Shares; and

                             (ii) If the registration is a "demand" registration
undertaken at the demand of persons other than the holders of Registrable
Securities pursuant to written contractual arrangements with such persons, (A)
first, the shares of Common Stock for the account of the demanding persons that
can be sold without exceeding the Maximum Number of Shares; (B) second, to the
extent that the Maximum Number of Shares has not been reached under the
foregoing clause (A), the shares of Common Stock or other securities that the
Company desires to sell that can be sold without exceeding the Maximum Number of
Shares; and (C) third, to the extent that the Maximum Number of Shares has not
been reached under the foregoing clauses (A) and (B), the Registrable Securities
as to which registration has been requested under this Section 5.2 (pro rata in
accordance with the number of shares of Registrable Securities held by each such
holder); and (D) fourth, to the extent that the Maximum Number of Shares has not
been reached under the foregoing clauses (A), (B) and (C), the shares of Common
Stock, if any, as to which registration has been requested pursuant to written
contractual piggy-back registration rights which other shareholders desire to
sell that can be sold without exceeding the Maximum Number of Shares.

                  5.2.2 Terms. The Company shall bear all fees and expenses
attendant to registering the Registrable Securities, including the expenses of
any legal counsel selected by the Holders to represent them in connection with
the sale of the Registrable Securities but the Holders shall pay any and all
underwriting commissions related to the Registrable Securities. In the event of
such a proposed registration, the Company shall furnish the then Holders of
outstanding Registrable Securities with not less than fifteen days written
notice prior to the proposed date of filing of such registration statement. Such
notice to the Holders shall continue to be given for each applicable
registration statement filed (during the period in which the Purchase Option is
exercisable) by the Company until such time as all of the Registrable Securities
have been registered and sold. The holders of the Registrable Securities shall
exercise the "piggy-back" rights provided for herein by giving written notice,
within ten days of the receipt of the Company's notice of its intention to file
a registration statement. The Company shall cause any registration statement
filed pursuant to the above "piggyback" rights to remain effective for at least
nine months from the date that the Holders of the Registrable Securities are
first given the opportunity to sell all of such securities.

         5.3 Damages. Should the registration or the effectiveness thereof
required by Sections 5.1 and 5.2 hereof be delayed by the Company or the Company
otherwise materially fails to comply with such provisions, the Company shall, in
addition to any other equitable or other relief available to the Holder(s), be
liable for any and all incidental, special and consequential damages sustained
by the Holder(s), including, but not limited to, the loss of any profits that
might have been received by the holder upon the sale of shares of Common Stock
or Warrants (and shares of Common Stock underlying the Warrants) underlying this
Purchase Option.

                                       5

         5.4      General Terms.

                  5.4.1 Indemnification. The Company shall indemnify the
Holder(s) of the Registrable Securities to be sold pursuant to any registration
statement hereunder and each person, if any, who controls such Holders within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage,
expense or liability (including all reasonable attorneys' fees and other
expenses reasonably incurred in investigating, preparing or defending against
litigation, commenced or threatened, or any claim whatsoever whether arising out
of any action between the underwriter and the Company or between the underwriter
and any third party or otherwise) to which any of them may become subject under
the Act, the Exchange Act or otherwise, arising from such registration statement
but only to the same extent and with the same effect as the provisions pursuant
to which the Company has agreed to indemnify the underwriters contained in
Section 6 of the Underwriting Agreement between the Company, Sunrise and the
other underwriters named therein dated the Effective Date. The Holder(s) of the
Registrable Securities to be sold pursuant to such registration statement, and
their successors and assigns, shall severally, and not jointly, indemnify the
Company, its officers and directors and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act, against all loss, claim, damage, expense or liability (including
all reasonable attorneys' fees and other expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, in writing, for specific inclusion in such registration statement to
the same extent and with the same effect as the provisions contained in Section
6 of the Underwriting Agreement pursuant to which the underwriters have agreed
to indemnify the Company.

                  5.4.2 Exercise of Purchase Options. Nothing contained in this
Purchase Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options or Warrants underlying such Purchase Options prior to or after
the initial filing of any registration statement or the effectiveness thereof.

                  5.4.3 Documents Delivered to Holders. The Company shall
furnish Sunrise, as representative of the Holders participating in any of the
foregoing offerings, a signed counterpart, addressed to the participating
Holders, of (i) an opinion of counsel to the Company, dated the effective date
of such registration statement (and, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under any
underwriting agreement related thereto), and (ii) a "cold comfort" letter dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting agreement) signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities. The Company shall
also deliver promptly to Sunrise, as representative of the Holders participating
in the offering, the correspondence and memoranda described below and copies of
all correspondence between the Commission and the Company, its counsel or
auditors and all memoranda relating to discussions with the Commission or its
staff with respect to the registration statement and permit Sunrise, as
representative of the Holders, to do such investigation, upon reasonable advance
notice, with respect to information contained in or omitted from the
registration state-

                                       6

ment as it deems reasonably necessary to comply with applicable securities laws
or rules of the National Association of Securities Dealers, Inc. ("NASD"). Such
investigation shall include access to books, records and properties and
opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable times
and as often as Sunrise, as representative of the Holders, shall reasonably
request. The Company shall not be required to disclose any confidential
information or other records to Sunrise, as representative of the Holders, or to
any other person, until and unless such persons shall have entered into
reasonable confidentiality agreements (in form and substance reasonably
satisfactory to the Company), with the Company with respect thereto.

                  5.4.4 Underwriting Agreement. The Company shall enter into an
underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this
Section 5, which managing underwriter shall be reasonably acceptable to the
Company. Such agreement shall be reasonably satisfactory in form and substance
to the Company, each Holder and such managing underwriters, and shall contain
such representations, warranties and covenants by the Company and such other
terms as are customarily contained in agreements of that type used by the
managing underwriter. The Holders shall be parties to any underwriting agreement
relating to an underwritten sale of their Registrable Securities and may, at
their option, require that any or all the representations, warranties and
covenants of the Company to or for the benefit of such underwriters shall also
be made to and for the benefit of such Holders. Such Holders shall not be
required to make any representations or warranties to or agreements with the
Company or the underwriters except as they may relate to such Holders and their
intended methods of distribution. Such Holders, however, shall agree to such
covenants and indemnification and contribution obligations for selling
stockholders as are customarily contained in agreements of that type used by the
managing underwriter. Further, such Holders shall execute appropriate custody
agreements and otherwise cooperate fully in the preparation of the registration
statement and other documents relating to any offering in which they include
securities pursuant to this Section 5. Each Holder shall also furnish to the
Company such information regarding itself, the Registrable Securities held by
it, and the intended method of disposition of such securities as shall be
required to effect the registration of the Registrable Securities.

                  5.4.5    Intentionally Omitted.

                  5.4.6 Supplemental Prospectus. Each Holder agrees, that upon
receipt of any notice from the Company of the happening of any event as a result
of which the prospectus included in the Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing, such Holder
will immediately discontinue disposition of Registrable Securities pursuant to
the Registration Statement covering such Registrable Securities until such
Holder's receipt of the copies of a supplemental or amended prospectus, and, if
so desired by the Company, such Holder shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate of
such destruction) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.

                                       7

6.       Adjustments.

         6.1      Adjustments to Exercise Price and Number of Securities. The
Exercise Price and the number of Units underlying the Purchase Option shall be
subject to adjustment from time to time as hereinafter set forth:

                  6.1.1 Stock Dividends - Split-Ups. If after the date hereof,
and subject to the provisions of Section 6.4 below, the number of outstanding
shares of Common Stock is increased by a stock dividend payable in shares of
Common Stock or by a split-up of shares of Common Stock or other similar event,
then, on the effective date thereof, the number of shares of Common Stock
underlying each of the Units purchasable hereunder shall be increased in
proportion to such increase in outstanding shares. In such case, the number of
shares of Common Stock, and the exercise price applicable thereto, underlying
the Warrants underlying each of the Units purchasable hereunder shall be
adjusted in accordance with the terms of the Warrants. For example, if the
Company declares a two-for-one stock dividend and at the time of such dividend
this Purchase Option is for the purchase of one Unit at $6.60 per whole Unit
(each Warrant underlying the Units is exercisable for $5.00 per share), upon
effectiveness of the dividend, this Purchase Option will be adjusted to allow
for the purchase of one Unit at $6.60 per Unit, each Unit entitling the holder
to receive two shares of Common Stock and four Warrants (each Warrant
exercisable for $2.50 per share).

                  6.1.2 Aggregation of Shares. If after the date hereof, and
subject to the provisions of Section 6.4, the number of outstanding shares of
Common Stock is decreased by a consolidation, combination or reclassification of
shares of Common Stock or other similar event, then, on the effective date
thereof, the number of shares of Common Stock underlying each of the Units
purchasable hereunder shall be decreased in proportion to such decrease in
outstanding shares. In such case, the number of shares of Common Stock, and the
exercise price applicable thereto, underlying the Warrants underlying each of
the Units purchasable hereunder shall be adjusted in accordance with the terms
of the Warrants.

                  6.1.3 Replacement of Securities upon Reorganization, etc. In
case of any reclassification or reorganization of the outstanding shares of
Common Stock other than a change covered by Section 6.1.1 or 6.1.2 hereof or
that solely affects the par value of such shares of Common Stock, or in the case
of any merger or consolidation of the Company with or into another corporation
(other than a consolidation or merger in which the Company is the continuing
corporation and that does not result in any reclassification or reorganization
of the outstanding shares of Common Stock), or in the case of any sale or
conveyance to another corporation or entity of the property of the Company as an
entirety or substantially as an entirety in connection with which the Company is
dissolved, the Holder of this Purchase Option shall have the right thereafter
(until the expiration of the right of exercise of this Purchase Option) to
receive upon the exercise hereof, for the same aggregate Exercise Price payable
hereunder immediately prior to such event, the kind and amount of shares of
stock or other securities or property (including cash) receivable upon such
reclassification, reorganization, merger or consolidation, or upon a dissolution
following any such sale or transfer, by a Holder of the number of shares of
Common Stock of the Company obtainable upon exercise of this Purchase Option and
the underlying Warrants immediately prior to such event; and if any
reclassification also results in a change in shares of Common Stock covered by
Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections
6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
similarly apply to successive reclassifications, reorganizations, mergers or
consolidations, sales or other transfers.

                                       8

                  6.1.4 Changes in Form of Purchase Option. This form of
Purchase Option need not be changed because of any change pursuant to this
Section, and Purchase Options issued after such change may state the same
Exercise Price and the same number of Units as are stated in the Purchase
Options initially issued pursuant to this Agreement. The acceptance by any
Holder of the issuance of new Purchase Options reflecting a required or
permissive change shall not be deemed to waive any rights to an adjustment
occurring after the Commencement Date or the computation thereof.

         6.2      [Intentionally Omitted]

         6.3      Substitute Purchase Option. In case of any consolidation of
the Company with, or merger of the Company with, or merger of the Company into,
another corporation (other than a consolidation or merger which does not result
in any reclassification or change of the outstanding Common Stock), the
corporation formed by such consolidation or merger shall execute and deliver to
the Holder a supplemental Purchase Option providing that the holder of each
Purchase Option then outstanding or to be outstanding shall have the right
thereafter (until the stated expiration of such Purchase Option) to receive,
upon exercise of such Purchase Option, the kind and amount of shares of stock
and other securities and property receivable upon such consolidation or merger,
by a holder of the number of shares of Common Stock of the Company for which
such Purchase Option might have been exercised immediately prior to such
consolidation, merger, sale or transfer. Such supplemental Purchase Option shall
provide for adjustments which shall be identical to the adjustments provided in
Section 6. The above provision of this Section shall similarly apply to
successive consolidations or mergers.

         6.4      Elimination of Fractional Interests. The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
or Warrants upon the exercise of the Purchase Option, nor shall it be required
to issue scrip or pay cash in lieu of any fractional interests, it being the
intent of the parties that all fractional interests shall be eliminated by
rounding any fraction up or down to the nearest whole number of Warrants, shares
of Common Stock or other securities, properties or rights.

7.       Reservation and Listing. The Company shall at all times reserve and
keep available out of its authorized shares of Common Stock, solely for the
purpose of issuance upon exercise of the Purchase Options or the Warrants
underlying the Purchase Option, such number of shares of Common Stock or other
securities, properties or rights as shall be issuable upon the exercise thereof.
The Company covenants and agrees that, upon exercise of the Purchase Options and
payment of the Exercise Price therefor, all shares of Common Stock and other
securities issuable upon such exercise shall be duly and validly issued, fully
paid and non-assessable and not subject to preemptive rights of any stockholder.
The Company further covenants and agrees that upon exercise of the Warrants
underlying the Purchase Options and payment of the respective Warrant exercise
price therefor, all shares of Common Stock and other securities issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable
and not subject to preemptive rights of any stockholder. As long as the Purchase
Options shall be outstanding, the Company shall use its best efforts to cause
all (i) Units and shares of Common Stock issuable upon exercise of the Purchase
Options, (ii) Warrants issuable upon exercise of the Purchase Options and (iii)
shares of Common Stock issuable upon exercise of the Warrants included in the
Units issuable upon exercise of the Purchase Option to be listed (subject to
official notice of issuance) on all securities exchanges (or, if applicable on
the Nasdaq National Market, SmallCap Market, OTC Bulletin Board or any successor
trading market) on which the Units, the Common Stock or the Warrants may then be
listed and/or quoted.

                                       9

8.       Certain Notice Requirements.

         8.1      Holder's Right to Receive Notice. Nothing herein shall be
construed as conferring upon the Holders the right to vote or consent as a
stockholder for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company. If, however, at any time
prior to the expiration of the Purchase Options and their exercise, any of the
events described in Section 8.2 shall occur, then, in one or more of said
events, the Company shall give written notice of such event at least fifteen
days prior to the date fixed as a record date or the date of closing the
transfer books for the determination of the stockholders entitled to such
dividend, distribution, conversion or exchange of securities or subscription
rights, or entitled to vote on such proposed dissolution, liquidation, winding
up or sale. Such notice shall specify such record date or the date of the
closing of the transfer books, as the case may be. Notwithstanding the
foregoing, the Company shall deliver to each Holder a copy of each notice given
to the other stockholders of the Company at the same time and in the same manner
that such notice is given to the stockholders.

         8.2      Events Requiring Notice. The Company shall be required to give
the notice described in this Section 8 upon one or more of the following events:
(i) if the Company shall take a record of the holders of its shares of Common
Stock for the purpose of entitling them to receive a dividend or distribution
payable otherwise than in cash, or a cash dividend or distribution payable
otherwise than out of retained earnings, as indicated by the accounting
treatment of such dividend or distribution on the books of the Company, or (ii)
the Company shall offer to all the holders of its Common Stock any additional
shares of capital stock of the Company or securities convertible into or
exchangeable for shares of capital stock of the Company, or any option, right or
warrant to subscribe therefor, or (iii) a dissolution, liquidation or winding up
of the Company (other than in connection with a consolidation or merger) or a
sale of all or substantially all of its property, assets and business shall be
proposed.

         8.3      Notice of Change in Exercise Price. The Company shall,
promptly after an event requiring a change in the Exercise Price pursuant to
Section 6 hereof, send notice to the Holders of such event and change ("Price
Notice"). The Price Notice shall describe the event causing the change and the
method of calculating same and shall be certified as being true and accurate by
the Company's President and Chief Financial Officer.

         8.4      Transmittal of Notices. All notices, requests, consents and
other communications under this Purchase Option shall be in writing and shall be
deemed to have been duly made when hand delivered, or mailed by express mail or
private courier service: (i) If to the registered Holder of the Purchase Option,
to the address of such Holder as shown on the books of the Company, or (ii) if
to the Company, to the following address or to such other address as the Company
may designate by notice to the Holders:

                                International Metal Enterprises, Inc.
                                1 Penn Plaza, Suite 2514

                                Attn:   Alan Kestenbaum, Chief Executive Officer

                                       10

9.       Miscellaneous.

         9.1      Amendments. The Company and Sunrise may from time to time
supplement or amend this Purchase Option without the approval of any of the
Holders in order to cure any ambiguity, to correct or supplement any provision
contained herein that may be defective or inconsistent with any other provisions
herein, or to make any other provisions in regard to matters or questions
arising hereunder that the Company and Sunrise may deem necessary or desirable
and that the Company and Sunrise deem shall not adversely affect the interest of
the Holders. All other modifications or amendments shall require the written

separate counterparts, each of which shall be deemed to be an original, but all
of which taken together shall constitute one and the same agreement, and shall
become effective when one or more counterparts has been signed by each of the
parties hereto and delivered to each of the other parties hereto.
