            Agreement, dated as of __________ ____, 200_, between
CORVETTEPORSCHE, a Delaware corporation (the "Company"), and [CHASEMELLON
SHAREHOLDER SERVICES, L.L.C.] , as rights agent (the "Rights Agent").

            The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding on           , 200_ (the
"Record Date"), each Right representing the right to purchase one one-hundredth
of a Preferred Share (as hereinafter defined), upon the terms and subject to the
conditions herein set forth, and has further authorized and directed the
issuance of one Right with respect to each Common Share that shall become
outstanding between the Record Date and the earliest of the Distribution Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined).

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

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

            (a)   "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the Common Shares of the Company then
outstanding, but shall not include [Corvette], [Porsche], the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or any
Subsidiary of the Company, or any entity holding Common Shares for or pursuant
to the terms of any such plan. Notwithstanding the foregoing, no Person shall
become an "Acquiring Person" as the result of an acquisition of Common Shares by
the Company which, by reducing
<PAGE>
the number of Common Shares of the Company outstanding, increases the
proportionate number of Common Shares of the Company beneficially owned by such
Person to 15% or more of the Common Shares of the Company then outstanding;
provided, however, that, if a Person shall become the Beneficial Owner of 15% or
more of the Common Shares of the Company then outstanding by reason of share
purchases by the Company and shall, after such share purchases by the Company,
become the Beneficial Owner of any additional Common Shares of the Company, then
such Person shall be deemed to be an "Acquiring Person," unless such Person is
not then the Beneficial Owner of 15% or more of the Common Shares of the Company
then outstanding. Notwithstanding the foregoing, if the Board of Directors of
the Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), became or has become such inadvertently, and such Person divested
or divests as promptly as practicable a sufficient number of Common Shares so
that such Person would no longer be an "Acquiring Person," as defined pursuant
to the foregoing provisions of this paragraph (a), then such Person shall not be
deemed to be an "Acquiring Person" for any purposes of this Agreement.

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

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

                                      -2-
<PAGE>
            (d)   A Person shall be deemed the "Beneficial Owner" of and shall
be deemed to "beneficially own" any securities:

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

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

                                      -3-
<PAGE>
            (iii) which are beneficially owned, directly or indirectly, by any
      other Person and with respect to which such Person or any of such Person's
      Affiliates or Associates has any agreement, arrangement or understanding
      (other than customary agreements with and between underwriters and selling
      group members with respect to a bona fide public offering of securities)
      for the purpose of acquiring, holding, voting (except to the extent
      contemplated by the proviso to Section 1(d)(ii)(B) hereof) or disposing of
      such securities of the Company.

            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.

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

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

            (g)   "Common Shares" when used with reference to the Company shall
mean the shares of common stock, par value $.01 per share, of the Company.
"Common Shares" when used with reference to any Person other than the Company
shall mean the capital stock (or equity interest) with the greatest voting power

            Section 2.  Appointment of Rights Agent. The Company hereby appoints
the Rights Agent to act as agent for the Company and the holders of the Rights
(who, in accordance with Section 3 hereof, shall, prior to the Distribution

with the terms and conditions hereof, and the Rights Agent hereby accepts such
appointment. The Company may from time to time appoint such co-Rights Agents as
it may deem necessary or desirable.

            Section 3.  Issue of Right Certificates. (a) Until the earlier of
(i) the Shares Acquisition Date or (ii) such date as may be determined by action
of the Board of Directors of the Company (prior to such time as any Person
becomes an Acquiring Person) after the date of the commencement by any Person
(other than the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or of any Subsidiary of the Company or any entity holding
Common Shares of the Company for or pursuant to the terms of any such plan) of a
tender or exchange offer the consummation of which would result in any Person
becoming the Beneficial Owner of Common Shares of the Company aggregating 15% or
more of the then outstanding Common Shares of the Company (including any such
date which is after the date of this Agreement and prior to the issuance of the
Rights; the earlier of such dates being herein referred to as the "Distribution
Date"), (x) the Rights will be evidenced (subject to the provisions of Section
3(b) hereof) by the certificates for Common Shares of the Company registered in
the names of the holders thereof (which certificates shall also be deemed to be
Right Certificates) and not by separate Right Certificates, and (y) the right to
receive Right Certificates will be transferable only in connection with the
transfer of Common Shares of the Company. As soon as practicable after the
Distribution Date, the Company will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested,

                                      -7-
<PAGE>
send) by first-class, insured, postage-prepaid mail, to each record holder of
Common Shares of the Company as of the Close of Business on the Distribution
Date, at the address of such holder shown on the records of the Company, a Right
Certificate, in substantially the form of Exhibit B hereto (a "Right
Certificate"), evidencing one Right for each Common Share so held. As of the
Distribution Date, the Rights will be evidenced solely by such Right
Certificates.

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

                                      -8-
<PAGE>
Shares of the Company represented thereby. The reference in the preceding two
sentences to certificates for Common Shares which immediately prior to the
Merger Effective Time represented shares of Porsche Common Stock shall be deemed
to include any uncertificated Porsche Common Shares as evidenced by the relevant
book-entry accounts and the stock distribution statements.

            (c)   Certificates (other than certificates which immediately prior
to the Merger Effective Time represented shares of Porsche Common Shares) for
Common Shares which become outstanding (including, without limitation,
reacquired Common Shares referred to in the last sentence of this paragraph (c))
after the Record Date but prior to the earliest of the Distribution Date, the
Redemption Date or the Final Expiration Date shall have impressed on, printed
on, written on or otherwise affixed to them the following legend:

      This certificate also evidences and entitles the holder hereof to certain
      rights as set forth in an Agreement between CORVETTEPORSCHE CORP. and
      [CHASEMELLON SHAREHOLDER SERVICES, L.L.C.], dated as of            , 200_,
      as it may be amended from time to time (the "Agreement"), the terms of
      which are hereby incorporated herein by reference and a copy of which is
      on file at the principal executive offices of CORVETTEPORSCHE CORP. Under
      certain circumstances, as set forth in the Agreement, such Rights (as
      defined in the Agreement) will be evidenced by separate certificates and
      will no longer be evidenced by this certificate. CORVETTEPORSCHE CORP.
      will mail to the holder of this certificate a copy of the Agreement
      without charge after receipt of a written request therefor. As set forth
      in the Agreement, Rights beneficially owned by any Person (as defined in
      the Agreement) who becomes an Acquiring Person (as defined in the
      Agreement) become null and void.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares of the Company
represented by such certificates shall be evidenced by such certificates alone,
and the surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares of the Company
represented thereby. In the event that the Company purchases or acquires any
Com-

                                      -9-
<PAGE>
mon Shares of the Company after the Record Date but prior to the Distribution
Date, any Rights associated with such Common Shares of the Company shall be
deemed cancelled and retired so that the Company shall not be entitled to
exercise any Rights associated with the Common Shares of the Company which are
no longer outstanding.

            Section 4.  Form of Right Certificates. The Right Certificates (and
the forms of election to purchase Preferred Shares and of assignment to be
printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto, and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any applicable
rule or regulation made pursuant thereto or with any applicable rule or
regulation of any stock exchange or the National Association of Securities
Dealers, Inc., or to conform to usage. Subject to the provisions of Section 22
hereof, the Right Certificates shall entitle the holders thereof to purchase
such number of one one-hundredths of a Preferred Share as shall be set forth
therein at the price per one one-hundredth of a Preferred Share set forth
therein (the "Purchase Price"), but the number of such one one-hundredths of a
Preferred Share and the Purchase Price shall be subject to adjustment as
provided herein.

            Section 5.  Countersignature and Registration. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its Chief Executive Officer, its President, any of its Vice Presidents or
its Treasurer, either manually or by facsimile signature, shall have affixed
thereto the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be manually countersigned by
the Rights Agent and shall not be

                                      -10-
<PAGE>
valid for any purpose unless countersigned. In case any officer of the Company
who shall have signed any of the Right Certificates shall cease to be such
officer of the Company before countersignature by the Rights Agent and issuance
and delivery by the Company, such Right Certificates, nevertheless, may be
countersigned by the Rights Agent and issued and delivered by the Company with
the same force and effect as though the individual who signed such Right
Certificates had not ceased to be such officer of the Company; and any Right
Certificate may be signed on behalf of the Company by any individual who, at the
actual date of the execution of such Right Certificate, shall be a proper
officer of the Company to sign such Right Certificate, although at the date of
the execution of this Agreement any such individual was not such an officer.

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

            Section 6.  Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. Subject
to the provisions of Section 14 hereof, at any time after the Close of Business
on the Distribution Date, and at or prior to the Close of Business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates
entitling the registered holder to purchase a like number of one one-

                                      -11-
<PAGE>
hundredths of a Preferred Share as the Right Certificate or Right Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Right Certificate or
Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
Person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

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

            Section 7.  Exercise of Rights; Purchase Price; Expiration Date of
Rights. (a) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein), in whole or in
part, at any time after the Distribution Date, upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the principal office of the Rights Agent,
together with payment of the Purchase Price for each one one-hundredth of a
Preferred Share as to which

                                      -12-
<PAGE>
the Rights are exercised, at or prior to the earliest of (i) the Close of
Business on ____________, 201_ (the "Final Expiration Date"), (ii) the time at
which the Rights are redeemed as provided in Section 23 hereof (the "Redemption
Date"), or (iii) the time at which such Rights are exchanged as provided in
Section 24 hereof.

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

            (c)   Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the shares to be purchased and an amount equal
to any applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof by certified check, cashier's
check or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i) (A) requisition from any transfer agent of the Preferred
Shares certificates for the number of Preferred Shares to be purchased and the
Company hereby irrevocably authorizes any such transfer agent to comply with all
such requests, or (B) requisition from the depositary agent depositary receipts
representing such number of one one-hundredths of a Preferred Share as are to be
purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent of the Preferred Shares
with such depositary agent) and the Company hereby directs such depositary agent
to comply with such request; (ii) when appropriate, requisition from the Company
the amount of cash to be paid in lieu of issuance of fractional shares in
accordance with Section 14 hereof; (iii) promptly after receipt of such
certificates or depositary receipts, cause the same to be delivered to or upon
the

                                      -13-
<PAGE>
order of the registered holder of such Right Certificate, registered in such
name or names as may be designated by such holder; and (iv) when appropriate,
after receipt, promptly deliver such cash to or upon the order of the registered
holder of such Right Certificate.

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

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

            Section 9.  Availability of Preferred Shares. The Company covenants
and agrees that it will cause to be reserved and kept available out of its
authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury the number of Preferred Shares that will

                                      -14-
<PAGE>
be sufficient to permit the exercise in full of all outstanding Rights in
accordance with Section 7 hereof. The Company covenants and agrees that it will
take all such action as may be necessary to ensure that all Preferred Shares
delivered upon exercise of Rights shall, at the time of delivery of the
certificates for such Preferred Shares (subject to payment of the Purchase
Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

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

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

                                      -15-
<PAGE>
have become the record holder of such shares on, and such certificate shall be
dated, the next succeeding Business Day on which the Preferred Shares transfer
books of the Company are open. Prior to the exercise of the Rights evidenced
thereby, the holder of a Right Certificate shall not be entitled to any rights
of a holder of Preferred Shares for which the Rights shall be exercisable,
including, without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

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

            (a)   (i)   In the event the Company shall at any time after the
date of this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification, and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the

                                      -16-
<PAGE>
Company were open, such holder would have owned upon such exercise and been
entitled to receive by virtue of such dividend, subdivision, combination or
reclassification; provided, however, that in no event shall the consideration to
be paid upon the exercise of one Right be less than the aggregate par value of
the shares of capital stock of the Company issuable upon exercise of one Right.

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

            From and after the occurrence of such event, any Rights that are or
were acquired or beneficially owned by any Acquiring Person (or any Associate or
Affiliate of such Acquiring Person) shall be void, and any holder of such Rights
shall thereafter have no right to exercise such Rights under any provision of
this Agreement. No Right Certificate shall be issued pursuant to Section 3
hereof that represents Rights beneficially owned by an Acquiring Person whose

                                      -17-
<PAGE>
Rights would be void pursuant to the preceding sentence or any Associate or
Affiliate thereof; no Right Certificate shall be issued at any time upon the
transfer of any Rights to an Acquiring Person whose Rights would be void
pursuant to the preceding sentence or any Associate or Affiliate thereof or to
any nominee of such Acquiring Person, Associate or Affiliate; and any Right
Certificate delivered to the Rights Agent for transfer to an Acquiring Person
whose Rights would be void pursuant to the preceding sentence shall be
cancelled.

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

            (b)   In case the Company shall fix a record date for the issuance
of rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current

                                      -18-
<PAGE>
per share market price of the Preferred Shares (as defined in Section 11(d)) on
such record date, the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of Preferred Shares outstanding on such record date plus the number of
Preferred Shares which the aggregate offering price of the total number of
Preferred Shares and/or equivalent preferred shares so to be offered (and/or the
aggregate initial conversion price of the convertible securities so to be
offered) would purchase at such current market price and the denominator of
which shall be the number of Preferred Shares outstanding on such record date
plus the number of additional Preferred Shares and/or equivalent preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible); provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right. In case such subscription price may be paid
in a consideration part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and holders
of the Rights. Preferred Shares owned by or held for the account of the Company
shall not be deemed outstanding for the purpose of any such computation. Such
adjustment shall be made successively whenever such a record date is fixed; and,
in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

            (c)   In case the Company shall fix a record date for the making of
a distribution to all holders of the Preferred Shares (including any such
distribution made in connection

                                      -19-
<PAGE>
with a consolidation or merger in which the Company is the continuing or
surviving corporation) of evidences of indebtedness or assets (other than a
regular quarterly cash dividend or a dividend payable in Preferred Shares) or
subscription rights or warrants (excluding those referred to in Section 11(b)
hereof), the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the then-current per
share market price of the Preferred Shares on such record date, less the fair
market value (as determined in good faith by the Board of Directors of the
Company, whose determination shall be described in a statement filed with the
Rights Agent and shall be binding on the Rights Agent and holders of the Rights)
of the portion of the assets or evidences of indebtedness so to be distributed
or of such subscription rights or warrants applicable to one Preferred Share and
the denominator of which shall be such then-current per share market price of
the Preferred Shares on such record date; provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than
the aggregate par value of the shares of capital stock of the Company to be
issued upon exercise of one Right. Such adjustments shall be made successively
whenever such a record date is fixed; and, in the event that such distribution
is not so made, the Purchase Price shall again be adjusted to be the Purchase
Price which would then be in effect if such record date had not been fixed.

            (d)   (i)   For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the 30 consecutive Trading
Days immediately prior to such date; provided, however, that, in the event that
the current per share market price of the Security is determined during a period
following the announcement by the issuer of such Security of (A) a dividend or
distribution on such Security

                                      -20-
<PAGE>
payable in shares of such Security or Securities convertible into such shares,
or (B) any subdivision, combination or reclassification of such Security and
prior to the expiration of 30 Trading Days after the ex-dividend date for such
dividend or distribution, or the record date for such subdivision, combination
or reclassification, then, and in each such case, the current per share market
price shall be appropriately adjusted to reflect the current market price per
share equivalent of such Security. The closing price for each day shall be the
last sale price, regular way, reported at or prior to 4:00 P.M. Eastern time or,
in case no such sale takes place on such day, the average of the bid and asked
prices, regular way, reported as of 4:00 P.M. Eastern time, in either case, as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Security is not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Security is listed or admitted to trading or, if the Security is
not listed or admitted to trading on any national securities exchange, the last
quoted price reported at or prior to 4:00 P.M. Eastern time or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported as of 4:00 P.M. Eastern time by NASDAQ or such other system
then in use, or, if on any such date the Security is not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Security selected by the Board
of Directors of the Company. The term "Trading Day" shall mean a day on which
the principal national securities exchange on which the Security is listed or
admitted to trading is open for the transaction of business, or, if the Security
is not listed or admitted to trading on any national securities exchange, a
Business Day.

                                      -21-
<PAGE>
                  (ii)  For the purpose of any computation hereunder, the
"current per share market price" of the Preferred Shares shall be determined in
accordance with the method set forth in Section 11(d)(i). If the Preferred
Shares are not publicly traded, the "current per share market price" of the
Preferred Shares shall be conclusively deemed to be the current per share market
price of the Common Shares as determined pursuant to Section 11(d)(i) hereof
(appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof), multiplied by one hundred. If
neither the Common Shares nor the Preferred Shares are publicly held or so
listed or traded, "current per share market price" shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent.

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

            (f)   If, as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Company other than Preferred
Shares, thereafter the number of such other shares so receivable upon exercise
of any Right shall be subject to adjustment from time to time in a man-

                                      -22-
<PAGE>
ner and on terms as nearly equivalent as practicable to the provisions with
respect to the Preferred Shares contained in Section 11(a) through (c) hereof,
inclusive, and the provisions of Sections 7, 9, 10 and 13 hereof with respect to
the Preferred Shares shall apply on like terms to any such other shares.

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

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

            (i)   The Company may elect, on or after the date of any adjustment
of the Purchase Price, to adjust the number of Rights in substitution for any
adjustment in the number of one one-hundredths of a Preferred Share purchasable
upon the exercise of a Right. Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the number of one
one-hundredths of a Preferred Share for which a Right was exercisable
immedi-

                                      -23-
<PAGE>
ately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights, indicating the record date for the adjustment, and, if known at the
time, the amount of the adjustment to be made. This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the Right
Certificates have been issued, shall be at least 10 days later than the date of
the public announcement. If Right Certificates have been issued, upon each
adjustment of the number of Rights pursuant to this Section 11(i), the Company
shall, as promptly as practicable, cause to be distributed to holders of record
of Right Certificates on such record date Right Certificates evidencing, subject
to Section 14 hereof, the additional Rights to which such holders shall be
entitled as a result of such adjustment, or, at the option of the Company, shall
cause to be distributed to such holders of record in substitution and
replacement for the Right Certificates held by such holders prior to the date of
adjustment, and upon surrender thereof, if required by the Company, new Right
Certificates evidencing all the Rights to which such holders shall be entitled
after such adjustment. Right Certificates so to be distributed shall be issued,
executed and countersigned in the manner provided for herein, and shall be
registered in the names of the holders of record of Right Certificates on the
record date specified in the public announcement.

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

                                      -24-
<PAGE>
and the number of one one-hundredths of a Preferred Share which were expressed
in the initial Right Certificates issued hereunder.

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

            (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 until the occurrence of such
event the issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

            (m)   Anything in this Section 11 to the contrary notwithstanding,
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it, in its sole discretion, shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or ex-

                                      -25-
<PAGE>
changeable for Preferred Shares, dividends on Preferred Shares payable in
Preferred Shares or issuance of rights, options or warrants referred to in
Section 11(b) hereof, hereafter made by the Company to holders of the Preferred
Shares shall not be taxable to such stockholders.

            (n)   In the event that, at any time after the date of this
Agreement and prior to the Distribution Date, the Company shall (i) declare or
pay any dividend on the Common Shares payable in Common Shares, or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then, in any such case, (A)
the number of one one-hundredths of a Preferred Share purchasable after such
event upon proper exercise of each Right shall be determined by multiplying the
number of one one-hundredths of a Preferred Share so purchasable immediately
prior to such event by a fraction, the numerator of which is the number of
Common Shares outstanding immediately before such event and the denominator of
which is the number of Common Shares outstanding immediately after such event,
and (B) each Common Share outstanding immediately after such event shall have
issued with respect to it that number of Rights which each Common Share
outstanding immediately prior to such event had issued with respect to it. The
adjustments provided for in this Section 11(n) shall be made successively
whenever such a dividend is declared or paid or such a subdivision, combination
or consolidation is effected.

            Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares and the Securities and Exchange Commission a copy

                                      -26-
<PAGE>
of such certificate and (c) if such adjustment occurs at any time after the
Distribution Date, mail a brief summary thereof to each holder of a Right
Certificate in accordance with Section 25 hereof.

            Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earning Power. In the event, directly or indirectly, at any time after a Person
has become an Acquiring Person, (a) the Company shall consolidate with, or merge
with and into, any other Person, (b) any Person shall merge with and into the
Company and the Company shall be the continuing or surviving corporation of such
merger and, in connection with such merger, all or part of the Common Shares
shall be changed into or exchanged for stock or other securities of any other
Person (or the Company) or cash or any other property, or (c) the Company shall
sell or otherwise transfer (or one or more of its Subsidiaries shall sell or
otherwise transfer), in one or more transactions, assets or earning power
aggregating 50% or more of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person other than the Company or
one or more of its wholly-owned Subsidiaries, then, and in each such case,
proper provision shall be made so that (i) each holder of a Right (except as
otherwise provided herein) shall thereafter have the right to receive, upon the
exercise thereof at a price equal to the then current Purchase Price multiplied
by the number of one one-hundredths of a Preferred Share for which a Right is
then exercisable (whether or not then exercisable for Preferred Shares), in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of Common Shares of such other Person (including the Company as
successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable
(whether or not then exercisable for Preferred Shares) and dividing that product
by (B) 50% of

                                      -27-
<PAGE>
the then current per share market price of the Common Shares of such other
Person (determined pursuant to Section 11(d) hereof) on the date of consummation
of such consolidation, merger, sale or transfer; (ii) the issuer of such Common
Shares shall thereafter be liable for, and shall assume, by virtue of such
consolidation, merger, sale or transfer, all the obligations and duties of the
Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be
deemed to refer to such issuer; and (iv) such issuer shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
Common Shares in accordance with Section 9 hereof) in connection with such
consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to the
Common Shares of the Company thereafter deliverable upon the exercise of the
Rights. The Company shall not consummate any such consolidation, merger, sale or
transfer unless, prior thereto, the Company and such issuer shall have executed
and delivered to the Rights Agent a supplemental agreement so providing. The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights. The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

            Section 14. Fractional Rights and Fractional Shares. (a) The Company
shall not be required to issue fractions of Rights or to distribute Right
Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right. For

                                      -28-
<PAGE>
the purposes of this Section 14(a), the current market value of a whole Right
shall be the closing price of the Rights for the Trading Day immediately prior
to the date on which such fractional Rights would have been otherwise issuable.
The closing price for any day shall be the last sale price, regular way, or, in
case no such sale takes place on such day, the average of the closing bid and
asked prices, regular way, in either case, as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Rights are not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the Rights are
listed or admitted to trading or, if the Rights are not listed or admitted to
trading on any national securities exchange, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported by NASDAQ or such other system then in use or, if on any
such date the Rights are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Rights selected by the Board of Directors of the Company. If on
any such date no such market maker is making a market in the Rights, the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

            (b)   The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute
certificates which evidence fractional Preferred Shares (other than fractions
which are integral multiples of one one-hundredth of a Preferred Share).
Fractions of Preferred Shares in integral multiples of one one-hundredth of a
Preferred Share may, at the election of the Company, be evidenced by depositary
receipts, pursuant to an

                                      -29-
<PAGE>
appropriate agreement between the Company and a depositary selected by it;
provided that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the Preferred Shares represented by such
depositary receipts. In lieu of fractional Preferred Shares that are not
integral multiples of one one-hundredth of a Preferred Share, the Company shall
pay to the registered holders of Right Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the
current market value of one Preferred Share. For the purposes of this Section
14(b), the current market value of a Preferred Share shall be the closing price
of a Preferred Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

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

            Section 15. Rights of Action. All rights of action in respect of
this Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in such holder's own behalf and
for such holder's own benefit, enforce, and may institute and maintain any suit,
action or proceeding against the Company to enforce, or otherwise act in respect
of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this
Agreement. With-

                                      -30-
<PAGE>
out 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 will be entitled to
specific performance of the obligations under, and injunctive relief against
actual or threatened violations of the obligations of any Person subject to,
this Agreement.

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

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

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

            (c)   the Company and the Rights Agent may deem and treat the person
in whose name the Right Certificate (or, prior to the Distribution Date, the
associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificate or the associated Common Shares
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary.

                                      -31-
<PAGE>
                  Section 17. Right Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

                  Section 18. Concerning the Rights Agent. The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder, and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability, or expense incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability in the premises.

                  The Rights Agent shall be protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it in
connection with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Shares or Com-

                                      -32-
<PAGE>
mon Shares or for other securities of the Company, instrument of assignment or
transfer, power of attorney, endorsement, affidavit, letter, notice, direction,
consent, certificate, statement, or other paper or document believed by it to be
genuine and to be signed, executed and, where necessary, verified or
acknowledged, by the proper person or persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

                  Section 19. Merger or Consolidation or Change of Name of
Rights Agent. Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the stock transfer or corporate trust powers of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto; provided that such corporation would be
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement, any of the Right Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and, in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and, in all such cases, such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

                  In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights

                                      -33-
<PAGE>
Agent may adopt the countersignature under its prior name and deliver Right
Certificates so countersigned; and, in case at that time any of the Right
Certificates shall not have been countersigned, the Rights Agent may countersign
such Right Certificates either in its prior name or in its changed name; and, in
all such cases, such Right Certificates shall have the full force provided in
the Right Certificates and in this Agreement.

                  Section 20. Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Company and the holders of
Right Certificates, by their acceptance thereof, shall be bound:

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

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking or suffering any
action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Treasurer or the
Secretary of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Agreement in reliance upon such
certificate.

                                      -34-
<PAGE>
                  (c) The Rights Agent shall be liable hereunder to the Company
and any other Person only for its own negligence, bad faith or willful
misconduct.

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

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

                  (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

                                      -35-
<PAGE>
acts, instruments and assurances as may reasonably be required by the Rights
Agent for the carrying out or performing by the Rights Agent of the provisions
of this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
any one of the Chairman of the Board, the Chief Executive Officer, the
President, any Vice President, the Secretary or the Treasurer of the Company,
and to apply to such officers for advice or instructions in connection with its
duties, and it shall not be liable for any action taken or suffered by it in
good faith in accordance with instructions of any such officer or for any delay
in acting while waiting for those instructions.

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

                  (i) The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys or agents, and the Rights Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company resulting from any such
act, default, neglect or misconduct, provided that reasonable care was exercised
in the selection and continued employment thereof.

                                      -36-
<PAGE>
                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Right Certificate
(which holder shall, with such notice, submit such holder's Right Certificate
for inspection by the Company), then the registered holder of any Right
Certificate may apply to any court of competent jurisdiction for the appointment
of a new Rights Agent. Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be a corporation organized and doing business
under the laws of the United States or of the [State of New York] (or of any
other state of the United States so long as such corporation is authorized to do
business as a banking institution in the [State of New York]), in good standing,
having an office in the [State of New York], which is authorized under such laws
to exercise corporate trust or stock transfer powers and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50 million. After appointment, the successor Rights Agent shall be

                                      -37-
<PAGE>
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Shares or Preferred Shares, and mail a notice thereof in writing to
the registered holders of the Right Certificates. Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

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

                  Section 23. Redemption. (a) The Board of Directors of the
Company may, at its option, at any time prior to such time as any Person becomes
an Acquiring Person, redeem all but not less than all the then outstanding
Rights at a redemption price of $.01 per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such redemption price being hereinafter referred to as the
"Redemption Price"). The redemption of the Rights by the Board of Directors of
the Company may be made effective

                                      -38-
<PAGE>
at such time, on such basis and with such conditions as the Board of Directors
of the Company, in its sole discretion, may establish.

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the redemption of the Rights pursuant to paragraph (a) of
this Section 23, and without any further action and without any notice, the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the Redemption Price. The Company shall
promptly give public notice of any such redemption; provided, however, that the
failure to give, or any defect in, any such notice shall not affect the validity
of such redemption. Within 10 days after such action of the Board of Directors
of the Company ordering the redemption of the Rights, the Company shall mail a
notice of redemption to all the holders of the then outstanding Rights at their
last addresses as they appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Shares. Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice. Each such
notice of redemption will state the method by which the payment of the
Redemption Price will be made. Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23 or in
Section 24 hereof, and other than in connection with the purchase of Common
Shares prior to the Distribution Date.

                  Section 24. Exchange (a) The Board of Directors of the Company
may, at its option, at any time after any Person becomes an Acquiring Person,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become void pursuant to the provisions of Section
11(a)(ii) hereof) for Common Shares at an exchange ratio

                                      -39-
<PAGE>
of one Common Share per Right, appropriately adjusted to reflect any adjustment
in the number of Rights pursuant to Section 11(i) (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors of the Company shall not be empowered to effect such
exchange at any time after any Person (other than the Company, any Subsidiary of
the Company, any employee benefit plan of the Company or any such Subsidiary, or
any entity holding Common Shares for or pursuant to the terms of any such plan),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the Common Shares then outstanding.

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

                                      -40-
<PAGE>
                  (c) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary to authorize additional
Common Shares for issuance upon exchange of the Rights. In the event the Company
shall, after good faith effort, be unable to take all such action as may be
necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exchange
of a Right, a number of Preferred Shares or fraction thereof such that the
current per share market price of one Preferred Share multiplied by such number
or fraction is equal to the current per share market price of one Common Share
as of the date of issuance of such Preferred Shares or fraction thereof.

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

                  Section 25. Notice of Certain Events. (a) In case the Company
shall, at any time after the Distribution Date, propose (i) to pay any dividend
payable in stock of any class to the holders of the Preferred Shares or to make
any other distribution to the holders of the Preferred Shares (other than a
regular quarterly cash dividend), (ii) to offer to the holders of the Pre-

                                      -41-
<PAGE>
ferred Shares rights or warrants to subscribe for or to purchase any additional
Preferred Shares or shares of stock of any class or any other securities, rights
or options, (iii) to effect any reclassification of the Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, or distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the Common Shares and/or Preferred
Shares, if any such date is to be fixed, and such notice shall be so given in
the case of any action covered by clause (i) or (ii) above at least 10 days
prior to the record date for determining holders of the Preferred Shares for
purposes of such action, and, in the case of any such other action, at least 10
days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Common Shares and/or Preferred
Shares, whichever shall be the earlier.

                  (b) In case the event set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall, as soon as practicable thereafter, give to
each holder of a Right Certificate, in

                                      -42-
<PAGE>
accordance with Section 26 hereof, a notice of the occurrence of such event,
which notice shall describe such event and the consequences of such event to
holders of Rights under Section 11(a)(ii) hereof.

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

time to time supplement or amend this Agreement without the approval of any
holders of Right Certificates in order to cure any ambiguity, to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, or to make any other provisions with respect

and 3(a) hereof to not less than 10% (the "Reduced Threshold"); provided,
however, that no Person who beneficially owns a number of Common Shares equal to
or greater than the Reduced Threshold shall become an Acquiring Person unless
such Person shall, after the public announcement of the Reduced Threshold,

than as a result of an acquisition of Common Shares by the Company) to an amount
equal to or greater than the greater of (x) the Reduced Threshold or (y) the sum
of (i) the lowest beneficial ownership of such Person as a percentage of the
outstanding Common Shares as of any date on or after the date of the public
announcement of such Reduced Threshold plus (ii) .001%.

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

                  CORVETTEPORSCHE CORP., a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Corporation"), hereby certifies that the following resolution was adopted
by the Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law at a meeting duly called and held on         , 200_:

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

                  Series A Junior Participating Preferred Stock:

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" (the
"Series A Preferred Stock") and the number of shares constituting the Series A
Preferred Stock shall be [10,000,000]. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

                  Section 2. Dividends and Distributions.

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

                                      A-1
<PAGE>
         with respect to dividends, the holders of shares of Series A Preferred
         Stock, in preference to the holders of Common Stock, par value $.01 per
         share (the "Common Stock"), of the Corporation, and of any other junior
         stock, shall be entitled to receive, when, as and if declared by the
         Board of Directors out of funds legally available for the purpose,
         quarterly dividends payable in cash on the first day of March, June,
         September and December in each year (each such date being referred to
         herein as a "Quarterly Dividend Payment Date"), commencing on the first
         Quarterly Dividend Payment Date after the first issuance of a share or
         fraction of a share of Series A Preferred Stock, in an amount per share
         (rounded to the nearest cent) equal to the greater of (a) $1 or (b)
         subject to the provision for adjustment hereinafter set forth, 100
         times the aggregate per share amount of all cash dividends, and 100
         times the aggregate per share amount (payable in kind) of all non-cash
         dividends or other distributions, other than a dividend payable in
         shares of Common Stock or a subdivision of the outstanding shares of
         Common Stock (by reclassification or otherwise), declared on the Common
         Stock since the immediately preceding Quarterly Dividend Payment Date
         or, with respect to the first Quarterly Dividend Payment Date, since
         the first issuance of any share or fraction of a share of Series A
         Preferred Stock. In the event the Corporation shall at any time declare
         or pay any dividend on the Common Stock payable in shares of Common
         Stock, or effect a subdivision or combination or consolidation of the
         outstanding shares of Common Stock (by reclassification or otherwise
         than by payment of a dividend in shares of Common Stock) into a greater
         or lesser number of shares of Common Stock, then in each such case the
         amount to which holders of shares of Series A Preferred Stock were
         entitled immediately prior to such event under clause (b) of the
         preceding sentence shall be adjusted by multiplying such amount by a
         fraction, the numerator of which is the number of shares of Common
         Stock outstanding immediately after such event and the denominator of
         which is the number of shares of Common Stock that were outstanding
         immediately prior to such event.

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

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

                                      A-2
<PAGE>
         dividends at the time accrued and payable on such shares shall be
         allocated pro rata on a share-by-share basis among all such shares at
         the time outstanding. The Board of Directors may fix a record date for
         the determination of holders of shares of Series A Preferred Stock
         entitled to receive payment of a dividend or distribution declared
         thereon, which record date shall be not more than 60 days prior to the
         date fixed for the payment thereof.

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

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

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

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

                  Section 4. Certain Restrictions.

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

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

                           (ii) declare or pay dividends, or make any other
                  distributions, on any shares of stock ranking on a parity
                  (either as to dividends or upon liquidation, dis-

                                      A-3
<PAGE>
                  solution or winding up) with the Series A Preferred Stock,
                  except dividends paid ratably on the Series A Preferred Stock
                  and all such parity stock on which dividends are payable or in
                  arrears in proportion to the total amounts to which the
                  holders of all such shares are then entitled;

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

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

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

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

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

                                      A-4
<PAGE>
amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up. In the event the Corporation shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

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

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

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

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

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

Introduction

                  On ______ __, 200_, the Board of Directors of our Company,
CorvettePorsche, a Delaware corporation, declared a dividend of one preferred
share purchase right (a "Right") for each outstanding share of common stock, par
value $.01 per share. The dividend is payable on _________ __, 200_ to the
stockholders of record on _________ __, 200_.

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

                  For those interested in the specific terms of the Rights
Agreement as made between our Company and [ChaseMellon Shareholder Services,
L.L.C.], as the Rights Agent, on ______ __, 200_, we provide the following
summary description. Please note, however, that this description is only a
summary, and is not complete, and should be read together with the entire Rights
Agreement, which has been filed with the Securities and Exchange Commission as
an exhibit to a Registration Statement on Form 8-A dated _________ __, 200_. A
copy of the agreement is available free of charge from our Company.

The Rights. Our Board authorized the issuance of a Right with respect to each
outstanding share of common stock on _________ __, 200_. The Rights will
initially trade with, and will be inseparable from, the common stock. The Rights
are evidenced only by certificates that represent shares of common stock. New
Rights will accompany any new shares of common stock we issue after _________
__, 200_ until the Distribution Date described below.

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

Exercisability.  The Rights will not be exercisable until

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

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

                                      C-1
<PAGE>
                  We refer to the date when the Rights become exercisable as the
"Distribution Date." Until that date, the common stock certificates will also
evidence the Rights, and any transfer of shares of common stock will constitute
a transfer of Rights. After that date, the Rights will separate from the common
stock and be evidenced by book-entry credits or by Rights certificates that we
will mail to all eligible holders of common stock. Any Rights held by an
Acquiring Person are void and may not be exercised.

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

Consequences of a Person or Group Becoming an Acquiring Person.

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

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

Preferred Share Provisions.

Each one one-hundredth of a Preferred Share, if issued:

-        will not be redeemable.

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

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

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

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

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

Expiration.  The Rights will expire on _________ __, 201_.

Redemption. Our Board may redeem the Rights for $.01 per Right at any time
before any person or group becomes an Acquiring Person. If our Board redeems any
Rights, it must redeem all of the Rights. Once the Rights are redeemed, the only
right of the holders of Rights will be to re-

                                       C-2
<PAGE>
ceive the redemption price of $.01 per Right. The redemption price will be
adjusted if we have a stock split or stock dividends of our common stock.

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

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

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