                                RIGHTS AGREEMENT


         This RIGHTS AGREEMENT, dated as of September 23, 1997 (this
"Agreement"), is made and entered into by and between DTE Energy Company, a
Michigan corporation (the "Company"), and The Detroit Edison Company, a
Michigan corporation (the "Rights Agent").

                                    RECITALS

         WHEREAS, on September 22, 1997, the Board of Directors of the Company
authorized and declared a dividend distribution of one right (a "Right") for
each share of Common Stock, without par value, of the Company (a "Common
Share") outstanding as of the Close of Business (as hereinafter defined) on
October 6, 1997 (the "Record Date"), each Right initially representing the
right to purchase one one-hundredth of a Preferred Share (as hereinafter
defined), on the terms and subject to the conditions herein set forth, and
further authorized and directed the issuance of one Right (subject to
adjustment as provided herein) with respect to each Common Share issued or
delivered by the Company (whether originally issued or delivered from the
Company's treasury) after the Record Date but prior to the earlier of the
Distribution Date (as hereinafter defined) and the Expiration Date (as
hereinafter defined) or as provided in Section 22.

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

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

         (a)     "Acquiring Person" means any Person (other than the Company or
any Related Person) who or which, together with all Affiliates and Associates
of such Person, is the Beneficial Owner of 10% or more of the then-outstanding
Common Shares; provided, however, that a Person will not be deemed to have
become an Acquiring Person solely as a result of a reduction in the number of
Common Shares outstanding unless and until such time as (i) such Person or any
Affiliate or Associate of such Person thereafter becomes the Beneficial Owner
of additional Common Shares representing 1% or more of the then-outstanding
Common Shares, other than as a result of a stock dividend, stock split or
similar transaction effected by the Company in which all holders of Common
Shares are treated equally, or (ii) any other Person who is the Beneficial
Owner of Common Shares representing 1% or more of the then-outstanding Common
Shares thereafter becomes an Affiliate or Associate of such Person; provided
further, however, that a Person permitted by Rule 13d-1(b)(1) promulgated under
the Exchange Act to report the beneficial ownership of all Common Shares
Beneficially Owned by it on Schedule 13G under the Exchange Act and which
properly reports all Common Shares Beneficially Owned by it on Schedule 13G
shall not be deemed to have become an Acquiring Person
<PAGE>   5

unless such Person, together with all Affiliates and Associates of such Person,
shall be the Beneficial Owner of 20% or more of the Common Shares then
outstanding; provided, however, the foregoing proviso shall not apply to any
Person who formerly was eligible to report its holdings on Schedule 13G under
the Exchange Act but who thereafter becomes ineligible to report holdings
on Schedule 13G and who at such time is the Beneficial Owner of 10% or more of
the then-outstanding Common Shares.  Notwithstanding the foregoing, if the
Board of Directors of the Company determines in good faith that a Person who
would otherwise be an Acquiring Person, as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently, and such
Person divests as promptly as practicable a sufficient number of Common Shares
so that such Person would no longer be an Acquiring Person, as defined pursuant
to the foregoing provisions of this paragraph (a), then such Person shall not
be deemed to be an Acquiring Person for any purposes of this Agreement.

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

         (c)     A Person will be deemed the "Beneficial Owner" of, and to
"Beneficially Own," any securities:

                   (i)    the beneficial ownership of which such Person or any
         of such Person's Affiliates or Associates, directly or indirectly, has
         the right to acquire (whether such right is exercisable immediately or
         only after the passage of time) pursuant to any agreement, arrangement
         or understanding (whether or not in writing), or upon the exercise of
         conversion rights, exchange rights, warrants, options or other rights
         (in each case, other than upon exercise or exchange of the Rights);
         provided, however, that a Person will 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

                  (ii)    which such Person or any of such Person's Affiliates
         or Associates, directly or indirectly, has or shares the right to vote
         or dispose of, including pursuant to any agreement, arrangement or
         understanding (whether or not in writing); or

                 (iii)    of which any other Person is the Beneficial Owner, if
         such Person or any of such Person's Affiliates or Associates has any
         agreement, arrangement, or understanding (whether or not in writing)
         with such other Person (or any of such other Person's Affiliates or
         Associates) with respect to acquiring, holding, voting or disposing of
         any securities of the Company;





                                      -2-
<PAGE>   6

provided, however, that a Person will not be deemed the Beneficial Owner of, or
to Beneficially Own, any security (A) if such Person has the right to vote such
security pursuant to an agreement, arrangement or understanding (whether or not
in writing) which (1) arises solely from a revocable proxy given to such Person
in response to a public proxy or consent solicitation made pursuant to, and in
accordance with, the applicable rules and regulations of the Exchange Act and
(2) is not also then reportable on Schedule 13D under the Exchange Act (or any
comparable or successor report), or (B) if such beneficial ownership arises
solely as a result of such Person's status as a "clearing agency," as defined
in Section 3(a)(23) of the Exchange Act; provided further, however, that
nothing in this paragraph (c) will cause a Person engaged in business as an
underwriter of securities to be the Beneficial Owner of, or to Beneficially
Own, any securities acquired through such Person's participation in good faith
in an underwriting syndicate until the expiration of 40 calendar days after the
date of such acquisition, or such later date as the Board of Directors of the
Company may determine in any specific case.

         (d)     "Business Day" means any day other than a Saturday, Sunday or
a day on which banking institutions in the State of New York (or such other

authorized or obligated by law or executive order to close.

time, on such date; provided, however, that if such date is not a Business Day

         (f)     "Common Shares" when used with reference to the Company means
the shares of Common Stock, without par value, of the Company; provided,
however, that, if the Company is the continuing or surviving corporation in a
transaction described in Section 13(a)(ii), "Common Shares" when used with
reference to the Company means shares of the capital stock or units of the
equity interests with the greatest aggregate voting power of the Company.
"Common Shares" when used with reference to any corporation or other legal
entity other than the Company, including an Issuer, means shares of the capital
stock or units of the equity interests with the greatest aggregate voting power
of such corporation or other legal entity.

         (g)     "Company" means DTE Energy Company, a Michigan corporation.

         (h)     "Distribution Date" means the earlier of:  (i) the Close of
Business on the tenth calendar day after the Share Acquisition Date, or (ii)

conditions hereof, and the Rights Agent hereby accepts such appointment and

rights and protections of, and subject to all of the applicable duties and

Agreement.

         3.      Issue of Right Certificates.  (a) Until the Distribution Date,
(i) the Rights will be evidenced by the certificates representing Common Shares
registered in the names of the record holders thereof (which certificates
representing Common Shares will also be deemed to be Right Certificates), (ii)
the Rights will be transferable only in connection with the transfer of the
underlying Common Shares, and (iii) the surrender for transfer of any
certificates evidencing Common Shares in respect of which Rights have been
issued will also constitute the transfer of the Rights associated with the
Common Shares evidenced by such certificates.  On or as promptly as practicable
after the Record Date, the Company will send 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 of such date, a copy of a Summary of Rights to Purchase Preferred Stock in
substantially the form attached as Exhibit C.

         (b)     Rights will be issued by the Company in respect of all Common
Shares (other than Common Shares issued upon the exercise or exchange of any
Right) issued or delivered by the Company (whether originally issued or
delivered from the Company's treasury) after the Record Date but prior to the
earlier of the Distribution Date and the Expiration Date.  Certificates
evidencing such Common Shares will have stamped on, impressed on, printed on,
written on, or otherwise affixed to them the following legend or such similar
legend as the Company may deem appropriate and as is not inconsistent with the
provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange or transaction reporting system on
which the Common Shares may from time to time be listed or quoted, or to
conform to usage:

         This Certificate also evidences and entitles the holder hereof to
         certain Rights as set forth in a Rights Agreement between DTE Energy
         Company, a Michigan corporation, and The Detroit Edison Company, dated
         as of September 23, 1997, as the same may be amended from time to time
         (the "Rights 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 DTE Energy Company.  The Rights are not
         exercisable prior to the occurrence of certain events specified in the
         Rights Agreement.  Under certain circumstances, as set forth in the
         Rights Agreement, such Rights may be redeemed, may expire, may be
         amended, or may be evidenced by separate certificates and no longer be
         evidenced by this Certificate.  DTE Energy Company will mail to the
         holder of this Certificate a copy of the Rights





                                      -6-
<PAGE>   10

         Agreement, as in effect on the date of mailing, without charge
         promptly after receipt of a written request therefor.  Under certain
         circumstances as set forth in the Rights Agreement, Rights
         beneficially owned by an Acquiring Person or any Affiliate or
         Associate of an Acquiring Person (as such terms are defined in the
         Rights Agreement) may become null and void.

         (c)     As promptly 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,
send), by first class, insured, postage prepaid mail, to each record holder of
Common Shares 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
evidencing one Right for each Common Share so held, subject to adjustment as
provided herein.  As of and after the Distribution Date, the Rights will be
evidenced solely by such Right Certificates.

         (d)     In the event that the Company purchases or otherwise acquires
any Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares will be deemed canceled and retired
so that the Company will not be entitled to exercise any Rights associated with
the Common Shares so purchased or acquired.

         4.      Form of Right Certificates.  The Right Certificates (and the
form of election to purchase, the form of assignment and the form of election
to purchase without the payment of cash to be printed on the reverse thereof)
will be substantially in the form attached as Exhibit B with such changes and
marks of identification or designation, and such legends, summaries or
endorsements printed thereon, as the Company may deem appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required
to comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or transaction
reporting system on which the Rights may from time to time be listed or quoted,
or to conform to usage.  Subject to the provisions of Section 22, the Right
Certificates, whenever issued, on their face will entitle the holders thereof
to purchase such number of one one-hundredths of a Preferred Share as are set
forth therein at the Purchase Price set forth therein, but the Purchase Price,
the number and kind of securities issuable upon exercise of each Right and the
number of Rights outstanding will be subject to adjustment as provided herein.

         5.      Countersignature and Registration.  (a) The Right Certificates
will be executed on behalf of the Company by its Chairman of the Board, any
Vice Chairman, its President or any Vice President, either manually or by
facsimile signature, and will have affixed thereto the Company's seal or a
facsimile thereof which





                                      -7-
<PAGE>   11

will be attested by the Secretary or an Assistant Secretary of the Company,
either manually or by facsimile signature.  The Right Certificates will be
countersigned by the Rights Agent and will not be valid for any purpose unless
so countersigned by the manual, or if permitted by applicable law and stock
exchange regulations, facsimile signature of the Rights Agent.  In case any
officer of the Company who signed any of the Right Certificates ceases to be
such officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right Certificates, nevertheless,
may be countersigned by the Rights Agent, and issued and delivered by the
Company with the same force and effect as though the person who signed such
Right Certificates had not ceased to be such officer of the Company; and any
Right Certificate may be signed on behalf of the Company by any person who, at
the actual date of the execution of such Right Certificate, is a proper officer
of the Company to sign such Right Certificate, although at the date of the
execution of this Rights Agreement any such person was not such officer.

         (b)     Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at the principal office of the Rights Agent designated for
such purpose and at such other offices as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange or any transaction reporting system on
which the Rights may from time to time be listed or quoted, books for
registration and transfer of the Right Certificates issued hereunder.  Such
books will 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.

         6.      Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.  (a)
Subject to the provisions of Sections 7(d) and 14, at any time after the Close
of Business on the Distribution Date and prior to the Expiration Date, any
Right Certificate or Right Certificates representing exercisable Rights may be
transferred, split up, combined or exchanged for another Right Certificate or
Right Certificates, entitling the registered holder to purchase a like number
of one one-hundredths of a Preferred Share (or other securities, as the case
may be) as the Right Certificate or Right Certificates surrendered then
entitled such holder (or former holder in the case of a transfer) to purchase.
Any registered holder desiring to transfer, split up, combine or exchange any
such Right Certificate or Rights Certificates must make such request in a
writing delivered to the Rights Agent and must surrender the Right Certificate
or Right Certificates to be transferred, split up, combined or exchanged at the
principal office of the Rights Agent designated for such purpose.  Thereupon or
as promptly as practicable thereafter, subject to the provisions of Sections
7(d) and 14, the Company will prepare, execute and deliver to the Rights Agent,
and the Rights Agent will countersign





                                      -8-
<PAGE>   12

and deliver, 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.

         (b)     Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation
of a Right Certificate and, in case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to them, and, if requested by the Company,
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 prepare, execute and
deliver a new Right Certificate of like tenor to the Rights Agent and the
Rights Agent will countersign and deliver such new Right Certificate to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed
or mutilated.

         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 and prior to the Expiration 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 office or
offices of the Rights Agent designated for such purpose, together with payment
in cash, in lawful money of the United States of America by certified check or
bank draft payable to the order of the Company, equal to the sum of (i) the
exercise price for the total number of securities as to which such surrendered
Rights are exercised and (ii) an amount equal to any applicable transfer tax
required to be paid by the holder of such Right Certificate in accordance with
the provisions of Section 9(c).

         (b)     Upon receipt of a Right Certificate representing exercisable
Rights with the form of election to purchase duly executed, accompanied by
payment as described above, the Rights Agent will promptly (i) requisition from
any transfer agent of the Preferred Shares (or make available, if the Rights
Agent is the transfer agent) certificates representing the number of one
one-hundredths of a Preferred Share to be purchased (and the Company hereby
irrevocably authorizes and directs its transfer agent to comply with all such
requests), or, if the Company elects to deposit Preferred Shares issuable upon
exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing such number of one
one-hundredths of a Preferred Share as are to be purchased (and the Company
hereby irrevocably authorizes and directs such depositary agent to comply with
all such requests), (ii) after receipt of such certificates (or depositary
receipts, as the case may be), cause the same to be delivered to or upon the
order of the registered holder of such Right Certificate, registered in such
name or names





                                      -9-
<PAGE>   13

as may be designated by such holder, (iii) when appropriate, requisition from
the Company or any transfer agent therefor (or make available, if the Rights
Agent is the transfer agent) certificates representing the number of equivalent
common shares to be issued in lieu of the issuance of Common Shares in
accordance with the provisions of Section 11(a)(iii), (iv) when appropriate,
after receipt of such certificates, cause the same to be delivered to or upon
the order of the registered holder of such Right Certificate, registered in
such name or names as may be designated by such holder, (v) when appropriate,
requisition from the Company the amount of cash to be paid in lieu of the
issuance of fractional shares in accordance with the provisions of Section 14
or in lieu of the issuance of Common Shares in accordance with the provisions
of Section 11(a)(iii), (vi) when appropriate, after receipt, deliver such cash
to or upon the order of the registered holder of such Right Certificate, and
(vii) when appropriate, deliver any due bill or other instrument provided to
the Rights Agent by the Company for delivery to the registered holder of such
Right Certificate as provided by Section 11(l).

         (c)     In case the registered holder of any Right Certificate
exercises less than all the Rights evidenced thereby, the Company will prepare,
execute and deliver a new Right Certificate evidencing Rights equivalent to the
Rights remaining unexercised and the Rights Agent will countersign and deliver
such new Right Certificate to the registered holder of such Right Certificate
or to his duly authorized assigns, subject to the provisions of Section 14.

         (d)     Notwithstanding anything in this Agreement to the contrary,
neither the Rights Agent nor the Company will be obligated to undertake any
action with respect to any purported transfer, split up, combination or
exchange of any Right Certificate pursuant to Section 6 or exercise of a Right
Certificate as set forth in this Section 7 unless the registered holder of such
Right Certificate has (i) completed and signed the certificate following the
form of assignment or the form of election to purchase, as applicable, set
forth on the reverse side of the Right Certificate surrendered for such
transfer, split up, combination, exchange or exercise and (ii) provided such
additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) or Affiliates or Associates thereof as the Company may
reasonably request.

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





                                      -10-
<PAGE>   14

retirement, and the Rights Agent will so cancel and retire, any other Right
Certificate purchased or acquired by the Company otherwise than upon the
exercise thereof.  The Rights Agent will deliver all canceled Right
Certificates to the Company, or will, at the written request of the Company,
destroy such canceled Right Certificates, and in such case will deliver a
certificate of destruction thereof to the Company.

         9.      Company Covenants Concerning Securities and Rights.  The
Company covenants and agrees that:

                 (a)      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, a number of Preferred Shares that will be
         sufficient to permit the exercise in full of all outstanding Rights in
         accordance with Section 7.

                 (b)      So long as the Preferred Shares (and, following the
         occurrence of a Triggering Event, Common Shares and/or other
         securities) issuable upon the exercise of the Rights may be listed on
         a national securities exchange, it will endeavor to cause, from and
         after such time as the Rights become exercisable, all securities
         reserved for issuance upon the exercise of Rights to be listed on such
         exchange upon official notice of issuance upon such exercise.

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

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





                                      -11-
<PAGE>   15

                 (e)      It will use its best efforts (i) to file on an
         appropriate form, as soon as practicable following the later of the
         Share Acquisition Date and the Distribution Date, a registration
         statement under the Securities Act with respect to the securities
         issuable upon exercise of the Rights, (ii) to cause such registration
         statement to become effective as soon as practicable after such
         filing, and (iii) to cause such registration statement to remain
         effective (with a prospectus at all times meeting the requirements of
         the Securities Act) until the earlier of (A) the date as of which the
         Rights are no longer exercisable for such securities and (B) the
         Expiration Date.  The Company will also take such action as may be
         appropriate under, or to ensure compliance with, the securities or
         "blue sky" laws of the various states in connection with the
         exercisability of the Rights.  The Company may temporarily suspend,
         for a period of time after the date set forth in clause (i) of the
         first sentence of this Section 9(e), the exercisability of the Rights
         in order to prepare and file such registration statement and to permit
         it to become effective.  Upon any such suspension, the Company will
         issue a public announcement stating that the exercisability of the
         Rights has been temporarily suspended, as well as a public
         announcement at such time as the suspension is no longer in effect.
         In addition, if the Company determines that a registration statement
         should be filed under the Securities Act or any state securities laws
         following the Distribution Date, the Company may temporarily suspend
         the exercisability of the Rights in each relevant jurisdiction until
         such time as a registration statement has been declared effective and,
         upon any such suspension, the Company will issue a public announcement
         stating that the exercisability of the Rights has been temporarily
         suspended, as well as a public announcement at such time as the
         suspension is no longer in effect.  Notwithstanding anything in this
         Agreement to the contrary, the Rights will not be exercisable in any
         jurisdiction if the requisite registration or qualification in such
         jurisdiction has not been effected or the exercise of the Rights is
         not permitted under applicable law.

                 (f)      Notwithstanding anything in this Agreement to the
         contrary, after the later of the Share Acquisition Date and the
         Distribution Date it will not take (or permit any Subsidiary to take)
         any action if at the time such action is taken it is reasonably
         foreseeable that such action will eliminate or otherwise diminish the
         benefits intended to be afforded by the Rights.

                 (g)      In the event that the Company is obligated to issue
         other securities of the Company and/or pay cash pursuant to Sections
         11, 13, 14 or 24 it will make all arrangements necessary so that such
         other securities and/or cash are available for distribution by the
         Rights Agent, if and when appropriate.





                                      -12-
<PAGE>   16

         10.     Record Date.  Each Person in whose name any certificate
representing Preferred Shares (or Common Shares and/or other securities, as the
case may be) is issued upon the exercise of Rights will for all purposes be
deemed to have become the holder of record of the Preferred Shares (or Common
Shares and/or other securities, as the case may be) represented thereby on, and
such certificate will be dated, the date upon which the Right Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the transfer books of
the Company for the Preferred Shares (or Common Shares and/or other securities,
as the case may be) are closed, such Person will be deemed to have become the
record holder of such securities on, and such certificate will be dated, the
next succeeding Business Day on which the transfer books of the Company for the
Preferred Shares (or Common Shares and/or other securities, as the case may be)
are open.  Prior to the exercise of the Rights evidenced thereby, the holder of
a Right Certificate will not be entitled to any rights of a holder of any
security for which the Rights are or may become exercisable, including without
limitation the right to vote, to receive dividends or other distributions, or
to exercise any preemptive rights, and will not be entitled to receive any
notice of any proceedings of the Company, except as provided herein.

         11.     Adjustment of Purchase Price, Number and Kind of Securities or
Number of Rights.  The Purchase Price, the number and kind of securities
issuable upon exercise of each Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 11.

         (a)       (i)    In the event that the Company at any time after the
         Record Date (A) declares a dividend on the Preferred Shares payable in
         Preferred Shares, (B) subdivides the outstanding Preferred Shares, (C)
         combines the outstanding Preferred Shares into a smaller number of
         Preferred Shares, or (D) issues 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/or the
         number and/or kind of shares of capital stock issuable on such date
         upon exercise of a Right, will be proportionately adjusted so that the
         holder of any Right exercised after such time is entitled to receive
         upon payment of the Purchase Price then in effect 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
         transfer books of the Company for the Preferred Shares were open, the
         holder of such Right would have owned upon such exercise (and, in the
         case of a





                                      -13-
<PAGE>   17

         reclassification, would have retained after giving effect to such
         reclassification) and would have 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 issuable upon exercise of one Right.  If an
         event occurs which would require an adjustment under both this Section
         11(a)(i) and Section 11(a)(ii) or Section 13, the adjustment provided
         for in this Section 11(a)(i) will be in addition to, and will be made
         prior to, any adjustment required pursuant to Section 11(a)(ii) or
         Section 13.

             (ii)    Subject to the provisions of Section 24, if:

              (A)  any Person becomes an Acquiring Person; or

              (B)  any Acquiring Person or any Affiliate or Associate of any
         Acquiring Person, directly or indirectly, (1) merges into the Company
         or otherwise combines with the Company and the Company is the
         continuing or surviving corporation of such merger or combination
         (other than in a transaction subject to Section 13), (2) merges or
         otherwise combines with any Subsidiary of the Company, (3) in one or
         more transactions (otherwise than in connection with the exercise,
         exchange or conversion of securities exercisable or exchangeable for
         or convertible into shares of any class of capital stock of the
         Company or any of its Subsidiaries) transfers cash, securities or any
         other property to the Company or any of its Subsidiaries in exchange
         (in whole or in part) for shares of any class of capital stock of the
         Company or any of its Subsidiaries or for securities exercisable or
         exchangeable for or convertible into shares of any class of capital
         stock of the Company or any of its Subsidiaries, or otherwise obtains
         from the Company or any of its Subsidiaries, with or without
         consideration, any additional shares of any class of capital stock of
         the Company or any of its Subsidiaries or securities exercisable or
         exchangeable for or convertible into shares of any class of capital
         stock of the Company or any of its Subsidiaries (otherwise than as
         part of a pro rata distribution to all holders of shares of any class
         of capital stock of the Company, or any of its Subsidiaries), (4)
         sells, purchases, leases, exchanges, mortgages, pledges, transfers or
         otherwise disposes (in one or more transactions) to, from, with or of,
         as the case may be, the Company or any of its Subsidiaries (otherwise
         than in a transaction subject to Section 13), any property, including
         securities, on terms and conditions less favorable to the Company than
         the Company would be able to obtain in an arm's-length transaction
         with an unaffiliated third party, (5) receives any compensation from
         the Company or any of its Subsidiaries other than compensation as a
         director or a regular full-time employee, in either case at rates
         consistent with the Company's (or its Subsidiaries')





                                      -14-
<PAGE>   18

         past practices, or (6) receives the benefit, directly or indirectly
         (except proportionately as a stockholder), of any loans, advances,
         guarantees, pledges or other financial assistance or any tax credits
         or other tax advantage provided by the Company or any of its
         Subsidiaries; or

                   (C)    during such time as there is an Acquiring Person,
         there is any reclassification of securities of the Company (including
         any reverse stock split), or any recapitalization of the Company, or
         any merger or consolidation of the Company with any of its
         Subsidiaries, or any other transaction or series of transactions
         involving the Company or any of its Subsidiaries (whether or not with
         or into or otherwise involving an Acquiring Person), other than a
         transaction subject to Section 13, which has the effect, directly or
         indirectly, of increasing by more than 1% the proportionate share of
         the outstanding shares of any class of equity securities of the
         Company or any of its Subsidiaries, or of securities exercisable or
         exchangeable for or convertible into equity securities of the Company
         or any of its Subsidiaries, of which an Acquiring Person, or any
         Affiliate or Associate of any Acquiring Person, is the Beneficial
         Owner;

         then, and in each such case, proper provision will be made so that
         each holder of a Right, except as provided below, will thereafter have
         the right to receive, upon exercise thereof in accordance with the
         terms of this Agreement at an exercise price per Right equal to the
         product of the then-current Purchase Price multiplied by the number of
         one one-hundredths of a Preferred Share for which a Right was
         exercisable immediately prior to the date of the occurrence of such
         Flip-in Event (or, if any other Flip-in Event shall have previously
         occurred, the product of the then-current Purchase Price multiplied by
         the number of one one-hundredths of a Preferred Share for which a
         Right was exercisable immediately prior to the date of the first
         occurrence of a Flip-in Event), in lieu of Preferred Shares, such
         number of Common Shares as equals the result obtained by (x)
         multiplying the then-current Purchase Price by the number of one
         one-hundredths of a Preferred Share for which a Right was exercisable
         immediately prior to the date of the occurrence of such Flip- in Event
         (or, if any other Flip-in Event shall have previously occurred,
         multiplying the then-current Purchase Price by the number of one
         one-hundredths of a Preferred Share for which a Right was exercisable
         immediately prior to the date of the first occurrence of a Flip-in
         Event), and dividing that product by (y) 50% of the current per share
         market price of the Common Shares (determined pursuant to Section
         11(d)) on the date of the occurrence of such Flip-in Event.
         Notwithstanding anything in this Agreement to the contrary, from and
         after the first occurrence of a Flip-in Event, any Rights that are
         Beneficially Owned by (A) any Acquiring Person (or any Affiliate or
         Associate of any Acquiring Person), (B) a

<PAGE>   19

         transferee of any Acquiring Person (or any such Affiliate or
         Associate) who becomes a transferee after the occurrence of a Flip-in
         Event, or (C) a transferee of any Acquiring Person (or any such
         Affiliate or Associate) who became a transferee prior to or
         concurrently with the occurrence of a Flip-in Event pursuant to either
         (1) a transfer from an Acquiring Person to holders of its equity
         securities or to any Person with whom it has any continuing agreement,
         arrangement or understanding regarding the transferred Rights or (2) a
         transfer which the Board of Directors of the Company has determined is
         part of a plan, arrangement or understanding which has the purpose or
         effect of avoiding the provisions of this Section 11(a)(ii), and
         subsequent transferees of any of such Persons, will be void without
         any further action and any holder of such Rights will thereafter have
         no rights whatsoever with respect to such Rights under any provision
         of this Agreement.  The Company will use all reasonable efforts to
         ensure that the provisions of this Section 11(a)(ii) are complied
         with, but will have no liability to any holder of Right Certificates
         or any other Person as a result of its failure to make any
         determinations with respect to an Acquiring Person or its Affiliates,
         Associates or transferees hereunder.  Upon the occurrence of a Flip-in
         Event, no Right Certificate that represents Rights that are or have
         become void pursuant to the provisions of this Section 11(a)(ii) will
         thereafter be issued pursuant to Section 3 or Section 6, and any Right
         Certificate delivered to the Rights Agent that represents Rights that
         are or have become void pursuant to the provisions of this Section
         11(a)(ii) will be canceled.  Upon the occurrence of a Flip-over Event,
         any Rights that shall not have been previously exercised pursuant to
         this Section 11(a)(ii) shall thereafter be exercisable only pursuant
         to Section 13 and not pursuant to this Section 11(a)(ii).

                 (iii)    Upon the occurrence of a Flip-in Event, if there are
         not sufficient Common Shares authorized but unissued or issued but not
         outstanding to permit the issuance of all the Common Shares issuable
         in accordance with Section 11(a)(ii) upon the exercise of a Right, the
         Board of Directors of the Company will use its best efforts promptly
         to authorize and, subject to the provisions of Section 9(e), make
         available for issuance additional Common Shares or other equity
         securities of the Company having equivalent voting rights and an
         equivalent value (as determined in good faith by the Board of
         Directors of the Company) to the Common Shares (for purposes of this
         Section 11(a)(iii), "equivalent common shares").  In the event that
         equivalent common shares are so authorized, upon the exercise of a
         Right in accordance with the provisions of Section 7, the registered
         holder will be entitled to receive (A) Common Shares, to the extent
         any are available, and (B) a number of equivalent common shares, which
         the Board of Directors of the Company has determined in good faith to
         have a value equivalent to the excess of (x) the aggregate current





                                      -16-
<PAGE>   20

         per share market value on the date of the occurrence of the most
         recent Flip-in Event of all the Common Shares issuable in accordance
         with Section 11(a)(ii) upon the exercise of a Right (the "Exercise
         Value") over (y) the aggregate current per share market value on the
         date of the occurrence of the most recent Flip-in Event of any Common
         Shares available for issuance upon the exercise of such Right;
         provided, however, that if at any time after 90 calendar days after
         the latest of the Share Acquisition Date, the Distribution Date and
         the date of the occurrence of the most recent Flip-in Event, there are
         not sufficient Common Shares and/or equivalent common shares
         available for issuance upon the exercise of a Right, then the Company
         will be obligated to deliver, upon the surrender of such Right  and
         without requiring payment of the Purchase Price, Common Shares (to the
         extent available), equivalent common shares (to the extent  available)
         and then cash (to the extent permitted by applicable law and any
         agreements or instruments to which the Company is a party       in
         effect immediately prior to the Share Acquisition Date), which
         securities and cash have an aggregate value equal to the excess of
         (1) the Exercise Value over (2) the product of the then-current
         Purchase Price multiplied by the number of one one-hundredths of a
         Preferred Share for which a Right was exercisable immediately prior to
         the date of the occurrence of the most recent Flip-in Event (or,
         if any other Flip-in Event shall have previously occurred, the product
         of the then-current Purchase Price multiplied by the number of
         one one-hundredths of a Preferred Share for which a Right would have
         been exercisable immediately prior to the date of the occurrence
         of such Flip-in Event if no other Flip-in Event had previously
         occurred).  To the extent that any legal or contractual restrictions
         prevent the Company from paying the full amount of cash payable in
         accordance with the foregoing sentence, the Company will pay to
         holders of the Rights as to which such payments are being made all
         amounts which are not then restricted on a pro rata basis and will
         continue to make payments on a pro rata basis as promptly as funds
         become available until the full amount due to each such Rights
         holder has been paid.

         (b)     In the event that the Company fixes a record date for the
issuance of rights, options or warrants to all holders of Preferred Shares
entitling them (for a period expiring within 45 calendar days after such record
date) to subscribe for or purchase Preferred Shares (or securities having
equivalent rights, privileges and preferences as the Preferred Shares (for
purposes of this Section 11(b), "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 current per share market price of the Preferred Shares
(determined pursuant to Section 11(d)) on such record date, the Purchase Price





                                      -17-
<PAGE>   21

to be in effect after such record date will be determined by multiplying the
Purchase Price in effect immediately prior to such record date by a fraction,
the numerator of which is 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 per
share market price and the denominator of which is 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 issuable upon exercise of
one Right.  In case such subscription price may be paid in a consideration part
or all of which is in a form other than cash, the value of such consideration
will be as determined in good faith by the Board of Directors of the Company,
whose determination will be described in a statement filed with the Rights
Agent.  Preferred Shares owned by or held for the account of the Company will
not be deemed outstanding for the purpose of any such computation.  Such
adjustment will 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 will be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

         (c)     In the event that the Company fixes a record date for the
making of a distribution to all holders of Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of
indebtedness, cash (other than a regular periodic cash dividend), assets, stock
(other than a dividend payable in Preferred Shares) or subscription rights,
options or warrants (excluding those referred to in Section 11(b)), the
Purchase Price to be in effect after such record date will be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which is the current per share market price of
the Preferred Shares (as determined pursuant to Section 11(d)) on such record
date or, if earlier, the date on which Preferred Shares begin to trade on an
ex-dividend or when issued basis for such distribution, less the fair market
value (as determined in good faith by the Board of Directors of the Company,
whose determination will be described in a statement filed with the Rights
Agent) of the portion of the evidences of indebtedness, cash, assets or stock
so to be distributed or of such subscription rights, options or warrants
applicable to one Preferred Share, and the denominator of which is such current
per share market price of the Preferred Shares; provided, however, that in no
event shall the consideration to be paid upon the exercise of one Right be less
than the aggregate par





                                      -18-
<PAGE>   22

value of the shares of capital stock issuable upon exercise of one Right.  Such
adjustments will be made successively whenever such a record date is fixed; and
in the event that such distribution is not so made, the Purchase Price will
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 Common Shares on any date will be
         deemed to be the average of the daily closing prices per share of such
         Common Shares 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 Common Shares is determined during a period
         following the announcement by the issuer of such Common Shares of (A)
         a dividend or distribution on such Common Shares payable in such
         Common Shares or securities convertible into such Common Shares (other
         than the Rights) or (B) any subdivision, combination or
         reclassification of such Common Shares, 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 will be appropriately adjusted to take into account
         ex-dividend trading or to reflect the current per share market price
         per Common Share equivalent.  The closing price for each day will 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 Common
         Shares 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 Common Shares are listed or
         admitted to trading or, if the Common Shares 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 Common
         Shares are not quoted by any such organization, the average of the
         closing bid and asked prices as furnished by a professional market
         maker making a market in the Common Shares selected by the Board of
         Directors of the Company.  If the Common Shares are not publicly held
         or not so listed or traded, or are not the subject of available bid
         and asked quotes, "current per share market price" will mean the fair
         value per share as determined in good faith by the Board of Directors
         of the Company, whose determination will be described in a statement
         filed with the Rights Agent.

                  (ii)    For the purpose of any computation hereunder, the
         "current per share market price" of the Preferred Shares will be
         determined in the same manner as set forth above for Common Shares in
         Section 11(d)(i), other than the last sentence thereof.  If the
         current per share market price of the Preferred Shares cannot be
         determined in the manner provided above, the "current per share market
         price" of the Preferred Shares will be conclusively deemed to be an
         amount equal to the current per share market price of the Common
         Shares multiplied by one hundred (as such number may be appropriately
         adjusted to reflect events such as stock splits, stock dividends,
         recapitalizations or similar transactions relating to the Common
         Shares occurring after the date of this Agreement).  If neither the
         Common Shares nor the Preferred Shares are publicly held or so listed
         or traded, or the subject of available bid and asked quotes, "current
         per share market price" of the Preferred Shares will mean the fair
         value per share as determined in good faith by the Board of Directors
         of the Company, whose determination will be described in a statement
         filed with the Rights Agent.  For all purposes of this Agreement, the
         current per share market price of one one-hundredth of a Preferred
         Share will be equal to the current per share market price of one
         Preferred Share divided by one hundred.

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

         (f)     If as a result of an adjustment made pursuant to Section
11(a), the holder of any Right thereafter exercised becomes entitled to receive
any securities of the Company other than Preferred Shares, thereafter the
number and/or kind of such other securities so receivable upon exercise of any
Right (and/or the Purchase Price in respect thereof) will be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Preferred Shares (and the
Purchase Price in respect thereof) contained in this Section 11, and the
provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares
(and the Purchase Price in respect thereof) will apply on like terms to any
such other securities (and the Purchase Price in respect thereof).





                                      -20-
<PAGE>   24

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

         (h)     Unless the Company has exercised its election as provided in
Section 11(i), upon each adjustment of the Purchase Price pursuant to Section
11(b) or Section 11(c), each Right outstanding immediately prior to the making
of such adjustment will 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
(i) multiplying (x) the number of one one-hundredths of a Preferred Share
issuable upon exercise of a Right immediately prior to such adjustment of the
Purchase Price by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

         (i)     The Company may elect, on or after the date of any adjustment
of the Purchase Price, to adjust the number of Rights in substitution for any
adjustment in the number of one one-hundredths of a Preferred Share issuable
upon the exercise of a Right.  Each of the Rights outstanding after such
adjustment of the number of Rights will be exercisable for the number of one
one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment.  Each Right held of record prior to such
adjustment of the number of Rights will 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 will 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.  Such 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, will be at least 10 calendar
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 will, as promptly as practicable, cause to be
distributed to holders of record of Right Certificates on such record date
Right Certificates evidencing, subject to the provisions of Section 14, the
additional Rights to which such holders are entitled as a result of such
adjustment, or, at the option of the Company, will 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 are entitled after such adjustment.  Right
Certificates so to be





                                      -21-
<PAGE>   25

distributed will be issued, executed, and countersigned in the manner provided
for herein (and may bear, at the option of the Company, the adjusted Purchase
Price) and will be registered in the names of the holders of record of Right
Certificates on the record date specified in the public announcement.

         (j)     Without respect to any adjustment or change in the Purchase
Price and/or the number and/or kind of securities issuable upon the exercise of
the Rights, the Right Certificates theretofore and thereafter issued may
continue to express the Purchase Price and the number and kind of securities
which were expressed in the initial Right Certificate 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 or below the then par value, if any, of any other
securities of the Company issuable upon exercise of the Rights, the Company
will take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid
and nonassessable Preferred Shares or such other securities, as the case may
be, at such adjusted Purchase Price.

         (l)     In any case in which this Section 11 otherwise requires that
an adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuance to the holder of any Right exercised after such record date
the number of Preferred Shares or other securities of the Company, if any,
issuable upon such exercise over and above the number of Preferred Shares or
other 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 delivers to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such
additional Preferred Shares or other securities upon the occurrence of the
event requiring such adjustment.

         (m)     Notwithstanding anything in this Agreement to the contrary,
the Company will be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in its good faith judgment the Board of Directors of the
Company determines to be advisable in order that any (i) consolidation or
subdivision of the Preferred Shares, (ii) issuance wholly for cash of Preferred
Shares at less than the current per share market price therefor, (iii) issuance
wholly for cash of Preferred Shares or securities which by their terms are
convertible into or exchangeable for Preferred Shares, (iv) stock dividends, or
(v) issuance of rights, options or warrants  referred to in this Section 11,
hereafter made by the Company to holders of its Preferred Shares is not taxable
to such stockholders.





                                      -22-
<PAGE>   26


         (n)     Notwithstanding anything in this Agreement to the contrary, in
the event that the Company at any time after the Record Date prior to the
Distribution Date (i) pays a dividend on the outstanding Common Shares payable
in Common Shares, (ii) subdivides the outstanding Common Shares, (iii) combines
the outstanding Common Shares into a smaller number of shares, or (iv) issues
any shares of its capital stock in a reclassification of the outstanding Common
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation), the
number of Rights associated with each Common Share then outstanding, or issued
or delivered thereafter but prior to the Distribution Date, will be
proportionately adjusted so that the number of Rights thereafter associated
with each Common Share following any such event equals the result obtained by
multiplying the number of Rights associated with each Common Share immediately
prior to such event by a fraction the numerator of which is the total number of
Common Shares outstanding immediately prior to the occurrence of the event and
the denominator of which is the total number of Common Shares outstanding
immediately following the occurrence of such event.  The adjustments provided
for in this Section 11(n) will be made successively whenever such a dividend is
paid or such a subdivision, combination or reclassification is effected.

         12.     Certificate of Adjusted Purchase Price or Number of
Securities.  Whenever an adjustment is made as provided in Section 11 or
Section 13, the Company will 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
Preferred Shares and the Common Shares a copy of such certificate, and (c) if
such adjustment is made after the Distribution Date, mail a brief summary of
such adjustment to each holder of a Right Certificate in accordance with
Section 26.

         13.     Consolidation, Merger or Sale or Transfer of Assets or Earning
                 Power.  (a) In the event that:

                   (i)    at any time after a Person has become an Acquiring
         Person, the Company consolidates with, or merges with or into, any
         other Person and the Company is not the continuing or surviving
         corporation of such consolidation or merger; or

                  (ii)    at any time after a Person has become an Acquiring
         Person, any Person consolidates with the Company, or merges with or
         into the Company, and the Company is the continuing or surviving
         corporation of such merger or consolidation and, in connection with
         such merger or consolidation, all or part of the Common Shares is
         changed into or exchanged for stock or other securities of any other
         Person or cash or any other property; or





                                      -23-
<PAGE>   27

                    (iii)    at any time after a Person has become an Acquiring
               Person, the Company, directly or indirectly, sells or otherwise
               transfers (or one or more of its Subsidiaries sells or otherwise
               transfers), in one or more transactions, assets or earning power
               (including without limitation securities creating any obligation
               on the part of the Company and/or any of its Subsidiaries)
               representing in the aggregate more than 50% of the assets or
               earning power of the Company and its Subsidiaries (taken as a
               whole) to any Person or Persons other than the Company or one or
               more of its wholly owned Subsidiaries;

         then, and in each such case, proper provision will be made so that
         from and after the later of the Distribution Date and the date of the
         occurrence of such Flip-over Event (A) each holder of a Right
         thereafter has the right to receive, upon the exercise thereof in
         accordance with the terms of this Agreement at an exercise price per
         Right equal to the product of the then-current Purchase Price
         multiplied by the number of one one-hundredths of a Preferred Share
         for which a Right was exercisable immediately prior to the Share
         Acquisition Date, such number of duly authorized, validly issued,
         fully paid, nonassessable and freely tradeable Common Shares of the
         Issuer, free and clear of any liens, encumbrances and other adverse
         claims and not subject to any rights of call or first refusal, as
         equals the result obtained by (x) multiplying the then-current
         Purchase Price by the number of one one-hundredths of a Preferred
         Share for which a Right is exercisable immediately prior to the Share
         Acquisition Date and dividing that product by (y) 50% of the current
         per share market price of the Common Shares of the Issuer (determined
         pursuant to Section 11(d)), on the date of the occurrence of such
         Flip-over Event; (B) the Issuer will thereafter be liable for, and
         will assume, by virtue of the occurrence of such Flip-over Event, all
         the obligations and duties of the Company pursuant to this Agreement;
         (C) the term "Company" will thereafter be deemed to refer to the
         Issuer; and (D) the Issuer will take such steps (including without
         limitation the reservation of a sufficient number of its Common Shares
         to permit the exercise of all outstanding Rights) in connection with
         such consummation as may be necessary to assure that the provisions
         hereof are thereafter applicable, as nearly as reasonably may be
         possible, in relation to its Common Shares thereafter deliverable upon
         the exercise of the Rights.

                 (b)      For purposes of this Section 13, "Issuer" means (i) in
         the case of any Flip-over Event described in Sections 13(a)(i) or (ii)
         above, the Person that is the continuing, surviving, resulting or
         acquiring Person (including the Company as the continuing or surviving
         corporation of a transaction described in Section 13(a)(ii) above), and
         (ii) in the case of any Flip-over Event described in Section 13(a)(iii)
         above, the Person that is the party receiving the greatest portion of
         the assets or earning power (including without limitation securities
         creating any obligation on the part of the Company and/or any of its
         Subsidiaries) transferred





                                      -24-
<PAGE>   28

pursuant to such transaction or transactions; provided, however, that, in any
such case, (A) if (1) no class of equity security of such Person is, at the
time of such merger, consolidation or transaction and has been continuously
over the preceding 12-month period, registered pursuant to Section 12 of the
Exchange Act, and (2) such Person is a Subsidiary, directly or indirectly, of
another Person, a class of equity security of which is and has been so
registered, the term "Issuer" means such other Person; and (B) in case such
Person is a Subsidiary, directly or indirectly, of more than one Person, a
class of equity security of two or more of which are and have been so
registered, the term "Issuer" means whichever of such Persons is the issuer of
the equity security having the greatest aggregate market value.
Notwithstanding the foregoing, if the Issuer in any of the Flip-over Events
listed above is not a corporation or other legal entity having outstanding
equity securities, then, and in each such case, (x) if the Issuer is directly
or indirectly wholly owned by a corporation or other legal entity having
outstanding equity securities, then all references to Common Shares of the
Issuer will be deemed to be references to the Common Shares of the corporation
or other legal entity having outstanding equity securities which ultimately
controls the Issuer, and (y) if there is no such corporation or other legal
entity having outstanding equity securities, (I) proper provision will be made
so that the Issuer creates or otherwise makes available for purposes of the
exercise of the Rights in accordance with the terms of this Agreement, a kind
or kinds of security or securities having a fair market value at least equal to
the economic value of the Common Shares which each holder of a Right would have
been entitled to receive if the Issuer had been a corporation or other legal
entity having outstanding equity securities; and (II) all other provisions of
this Agreement will apply to the issuer of such securities as if such
securities were Common Shares.

          (c)    The Company will not consummate any Flip-over Event if, (i) at
the time of or immediately after such Flip-over Event, there are or would be any
rights, warrants, instruments or securities outstanding or any agreements or
arrangements in effect which would eliminate or substantially diminish the
benefits intended to be afforded by the Rights, (ii) prior to, simultaneously
with or immediately after such Flip-over Event, the stockholders of the Person
who constitutes, or would constitute, the Issuer for purposes of Section 13(a)
shall have received a distribution of Rights previously owned by such Person or
any of its Affiliates or Associates, or (iii) the form or nature of the
organization of the Issuer would preclude or limit the exercisability of the
Rights.  In addition, the Company will not consummate any Flip-over Event unless
the Issuer has a sufficient number of authorized Common Shares (or other
securities as contemplated in Section 13(b) above) which have not been issued or
reserved for issuance to permit the exercise in full of the Rights in accordance
with this Section 13 and unless prior to such consummation the Company and the
Issuer have executed and delivered to the Rights Agent a supplemental agreement
providing for the terms set forth in subsections (a) and





                                      -25-
<PAGE>   29

(b) of this Section 13 and further providing that as promptly as practicable
after the consummation of any Flip-over Event, the Issuer will:

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

                   (B)    take all such action as may be appropriate under, or
         to ensure compliance with, the securities or "blue sky" laws of the
         various states in connection with the exercisability of the Rights;
         and

                   (C)    deliver to holders of the Rights historical financial
         statements for the Issuer and each of its Affiliates which comply in
         all respects with the requirements for registration on Form 10 under
         the Exchange Act.

         (d)     The provisions of this Section 13 will similarly apply to
successive mergers or consolidations or sales or other transfers.  In the event
that a Flip-over Event occurs at any time after the occurrence of a Flip-in
Event, except for Rights that have become void pursuant to Section 11(a)(ii),
Rights that shall not have been previously exercised will cease to be
exercisable in the manner provided in Section 11(a)(ii) and will thereafter be
exercisable in the manner provided in Section 13(a).

         14.     Fractional Rights and Fractional Securities.  (a) The Company
will not be required to issue fractions of Rights or to distribute Right
Certificates which evidence fractional Rights.  In lieu of such fractional
Rights, the Company will pay as promptly as practicable to the registered
holders of the Right Certificates with regard to which such fractional Rights
otherwise would be issuable, an amount in cash equal to the same fraction of
the current market value of one Right.  For the purposes of this Section 14(a),
the current market value of one Right is the closing price of the Rights for
the Trading Day immediately prior to the date on which such fractional Rights
otherwise would have been issuable.  The closing price for any day is 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





                                      -26-
<PAGE>   30

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 the Rights are
not publicly held or are not so listed or traded, or are not the subject of
available bid and asked quotes, the current market value of one Right will mean
the fair value thereof as determined in good faith by the Board of Directors of
the Company, whose determination will be described in a statement filed with
the Rights Agent.

         (b)     The Company will not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-hundredth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share).  Fractions of Preferred Shares in integral multiples of one
one-hundredth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts pursuant to an appropriate agreement between
the Company and a depositary selected by it, provided that such agreement
provides that the holders of such depositary receipts 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 may pay to any Person to whom
or which such fractional Preferred Shares would otherwise be issuable an amount
in cash equal to the same fraction of the current market value of one Preferred
Share.  For purposes of this Section 14(b), the current market value of one
Preferred Share is the closing price of the Preferred Shares (as determined in
the same manner as set forth for Common Shares in the second sentence of
Section 11(d)(i)) for the Trading Day immediately prior to the date of such
exercise; provided, however, that if the closing price of the Preferred Shares
cannot be so determined, the closing price of the Preferred Shares for such
Trading Day will be conclusively deemed to be an amount equal to the closing
price of the Common Shares (determined pursuant to the second sentence of
Section 11(d)(i)) for such Trading Day multiplied by one hundred (as such
number may be appropriately adjusted to reflect events such as stock splits,
stock dividends, recapitalizations or similar transactions relating to the
Common Shares occurring after the date of this Agreement); provided further,
however, that if neither the Common Shares nor the Preferred Shares are
publicly held or listed or admitted to trading on any national securities
exchange, or the subject of available bid and asked quotes, the current market
value of one Preferred Share will mean the fair value thereof as determined in
good faith by the Board of Directors of the Company, whose





                                      -27-
<PAGE>   31

determination will be described in a statement filed with the Rights Agent.

         (c)     Following the occurrence of a Triggering Event, the Company
will not be required to issue fractions of Common Shares or other securities
issuable upon exercise or exchange of the Rights or to distribute certificates
which evidence any such fractional securities.  In lieu of issuing any such
fractional securities, the Company may pay to any Person to whom or which such
fractional securities would otherwise be issuable an amount in cash equal to
the same fraction of the current market value of one such security.  For
purposes of this Section 14(c), the current market value of one Common Share or
other security issuable upon the exercise or exchange of Rights is the closing
price thereof (as determined in the same manner as set forth for Common Shares
in the second sentence of Section 11(d)(i)) for the Trading Day immediately
prior to the date of such exercise or exchange; provided, however, that if
neither the Common Shares nor any such other securities are publicly held or
listed or admitted to trading on any national securities exchange, or the
subject of available bid and asked quotes, the current market value of one
Common Share or such other security will mean the fair value thereof as
determined in good faith by the Board of Directors of the Company, whose
determination will mean the fair value thereof as be described in a statement
filed with the Rights Agent.

         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, 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 holder of any Common Shares), may in his own
behalf and for his own benefit enforce, and may institute and maintain any
suit, action or proceeding against the Company to enforce, or otherwise act in
respect of, his right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this
Agreement.  Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
will be entitled to specific performance of the obligations under this
Agreement, and injunctive relief against actual or threatened violations of the
obligations of any Person subject to this Agreement.

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





                                      -28-
<PAGE>   32

                 (a)      Prior to the Distribution Date, the Rights are
         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 designated for
         such purpose, duly endorsed or accompanied by a proper instrument of
         transfer;

                 (c)      The Company and the Rights Agent may deem and treat
         the person in whose name the Right Certificate (or, prior to the
         Distribution Date, the associated Common Share 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 Share certificate made by
         anyone other than the Company or the Rights Agent) for all purposes
         whatsoever, and neither the Company nor the Rights Agent will be
         affected by any notice to the contrary;

                 (d)      Such holder expressly waives any right to receive any
         fractional Rights and any fractional securities upon exercise or
         exchange of a Right, except as otherwise provided in Section 14.

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

         17.     Right Certificate Holder Not Deemed a Stockholder.  No holder,
as such, of any Right Certificate will be entitled to vote, receive dividends,
or be deemed for any purpose the holder of Preferred Shares or any other
securities of the Company which may at any time be issuable upon the exercise
of the Rights represented thereby, nor will 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





                                      -29-
<PAGE>   33

as provided in Section 25), 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 of this Agreement or
exchanged pursuant to the provisions of Section 24.

         18.     Concerning the Rights Agent.  (a) The Company will 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 will also indemnify the Rights Agent for, and hold it
harmless against, any loss, liability, suit, action, proceeding or expense,
incurred without negligence, bad faith, or willful misconduct on the part of
the Rights Agent, for anything done or omitted to be done by the Rights Agent
in connection with the acceptance and administration of this Agreement,
including the costs and expenses of defending against any claim of liability
arising therefrom, directly or indirectly.

         (b)     The Rights Agent will be protected and will 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 evidencing Preferred Shares or Common Shares or
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.

         19.     Merger or Consolidation or Change of Name of Rights Agent.
(a) Any corporation into which the Rights Agent or any successor Rights Agent
may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent is a party, or any corporation succeeding to the
corporate trust business of the Rights Agent or any successor Rights Agent,
will 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.  If
at the time such successor Rights Agent succeeds to the agency created by this
Agreement any of the Right Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of
the predecessor Rights Agent and deliver such Right Certificates so
countersigned; and if at that time any of the Right Certificates shall not have
been countersigned, any successor Rights Agent may countersign such Right
Certificates either in the name of the predecessor Rights





                                      -30-
<PAGE>   34

Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates will have the full force provided in the Right Certificates
and in this Agreement.

         (b)     If at any time the name of the Rights Agent changes and at
such time any of the Right Certificates have been countersigned but not
delivered, the Rights Agent may adopt the countersignature under its prior name
and deliver Right Certificates so countersigned; and if at that time any of the
Right Certificates have not 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 will have the full force
provided in the Right Certificates and in this Agreement.

         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, will 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
         will 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 deems 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 President, any
         Vice President, the Secretary or the Treasurer of the Company and
         delivered to the Rights Agent, and such certificate will be full
         authorization to the Rights Agent for any action taken or suffered in
         good faith by it under the provisions of this Agreement in reliance
         upon such certificate.

                 (c)      The Rights Agent will be liable hereunder only for
         its own negligence, bad faith or willful misconduct.

                 (d)      The Rights Agent will 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 will be deemed to have been made by the Company
         only.

                 (e)      The Rights Agent will not be under any responsibility
         in respect of the validity of this Agreement or the execution and
         delivery hereof (except the due execution and delivery hereof by the
         Rights Agent) or in respect of the





                                      -31-
<PAGE>   35

         validity or execution of any Right Certificate (except its
         countersignature thereof); nor will it be responsible for any breach
         by the Company of any covenant contained in this Agreement or in any
         Right Certificate; nor will it be responsible for any adjustment
         required under the provisions of Sections 11 or 13 (including any
         adjustment which results in Rights becoming void) or responsible for
         the manner, method or amount of any such adjustment or the
         ascertaining of the existence of facts that would require any such
         adjustment (except with respect to the exercise of Rights evidenced by
         Right Certificates after actual notice of any such adjustment); nor
         will it by any act hereunder be deemed to make any representation or
         warranty as to the authorization or reservation of any shares of stock
         or other securities to be issued pursuant to this Agreement or any
         Right Certificate or as to whether any shares of stock or other
         securities will, when issued, be duly authorized, validly issued,
         fully paid and nonassessable.

                 (f)      The Company will perform, execute, acknowledge and
         deliver or cause to be performed, executed, acknowledged and delivered
         all such further and other acts, instruments and assurances as may
         reasonably be required by the Rights Agent for the carrying out or
         performing by the Rights Agent of the provisions of this Agreement.

                 (g)      The Rights Agent is hereby authorized and directed to
         accept instructions with respect to the performance of its duties
         hereunder from any one of the Chairman of the Board, the 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 will not be liable for any action taken or
         suffered to be taken by it in good faith in accordance with
         instructions of any such officer.

                 (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 will preclude the Rights Agent from acting
         in any other capacity for the Company or for any other Person.

                 (i)      The Rights Agent may execute and exercise any of the
         rights or powers hereby vested in it or perform any duty hereunder
         either itself or by or through its attorneys or agents, and the Rights
         Agent will 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,





                                      -32-
<PAGE>   36

         provided reasonable care was exercised in the selection and continued
         employment thereof.  The Rights Agent will not be under any duty or
         responsibility to ensure compliance with any applicable federal or
         state securities laws in connection with the issuance, transfer or
         exchange of Right Certificates.

                 (j)      If, with respect to any Right Certificate surrendered
         to the Rights Agent for exercise, transfer, split up, combination or
         exchange, either (i) the certificate attached to the form of
         assignment or form of election to purchase, as the case may be, has
         either not been completed or indicates an affirmative response to
         clause 1 or 2 thereof, or (ii) any other actual or suspected
         irregularity exists, the Rights Agent will not take any further action
         with respect to such requested exercise, transfer, split up,
         combination or exchange without first consulting with the Company, and
         will thereafter take further action with respect thereto only in
         accordance with the Company's written instructions.

         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 calendar days' notice in writing mailed to the Company and to each
transfer agent of the Preferred Shares or the Common 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 calendar 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
Preferred Shares and the Common Shares by registered or certified mail, and to
the holders of the Right Certificates by first class mail.  If the Rights Agent
resigns or is removed or otherwise becomes incapable of acting, the Company
will appoint a successor to the Rights Agent.  If the Company fails to make
such appointment within a period of 30 calendar days after giving notice of
such removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a
Right Certificate (who will, with such notice, submit his Right Certificate for
inspection by the Company), then the registered holder of any Right Certificate
may apply to any court of competent jurisdiction for the appointment of a new
Rights Agent.  Any successor Rights Agent, whether appointed by the Company or
by such a court, will be a corporation or other legal entity organized and
doing business under the laws of the United States or of any State, in good
standing, having an office or agency in the State of New York or elsewhere as
may then be required under any applicable stock exchange or other rule or
regulation, 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 will be vested with the same powers, rights, duties, and
responsibilities as if it had





                                      -33-
<PAGE>   37

been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent will 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 will file
notice thereof in writing with the predecessor Rights Agent and each transfer
agent of the Preferred Shares or the Common 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, will 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.

         22.     Issuance of New Right Certificates.  Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Right Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or
change in the Purchase Price per share and the number or kind of securities
issuable upon exercise of the Rights made in accordance with the provisions of
this Agreement.  In addition, in connection with the issuance or sale by the
Company of Common Shares following the Distribution Date and prior to the
Expiration Date, the Company (a) will, with respect to Common Shares so issued
or sold pursuant to the exercise, exchange or conversion of securities (other
than Rights) issued prior to the Distribution Date which are exercisable or
exchangeable for, or convertible into Common Shares, and (b) may, in any other
case, if deemed necessary, appropriate or desirable by the Board of Directors
of the Company, issue Right Certificates representing an equivalent number of
Rights as would have been issued in respect of such Common Shares if they had
been issued or sold prior to the Distribution Date, as appropriately adjusted
as provided herein as if they had been so issued or sold; provided, however,
that (i) no such Right Certificate will be issued if, and to the extent that,
in its good faith judgment the Board of Directors of the Company determines
that the issuance of such Right Certificate could have a material adverse tax
consequence to the Company or to the Person to whom or which such Right
Certificate otherwise would be issued and (ii) no such Right Certificate will
be issued if, and to the extent that, appropriate adjustment otherwise has been
made in lieu of the issuance thereof.

         23.     Redemption.  (a) Prior to the Expiration Date, the Board of
Directors of the Company may, at its option, redeem all but not less than all
of the then-outstanding Rights at the Redemption Price at any time prior to the
Close of Business on the later of (i) the date of the first occurrence of a
Triggering Event and (ii) the Distribution Date.  Any such redemption will be
effective immediately upon the action of the Board of Directors of the Company
ordering the same, unless such action of the Board of Directors of the Company
expressly provides that such redemption





                                      -34-
<PAGE>   38

will be effective at a subsequent time or upon the occurrence or nonoccurrence
of one or more specified events (in which case such redemption will be
effective in accordance with the provisions of such action of the Board of
Directors of the Company).

         (b)     Immediately upon the effectiveness of the redemption of the
Rights as provided in Section 23(a), 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 will be to receive the Redemption Price,
without interest thereon.  Promptly after the effectiveness of the redemption
of the Rights as provided in Section 23(a), the Company will publicly announce
such redemption and, within 10 calendar days thereafter, will give notice of
such redemption to the holders of the then-outstanding Rights by mailing such
notice to all such holders at their last addresses as they appear upon the
registry books of the Company; provided, however, that the failure to give, or
any defect in, any such notice will not affect the validity of the redemption
of the Rights.  Any notice which is mailed in the manner herein provided will
be deemed given, whether or not the holder receives the notice.  The notice of
redemption mailed to the holders of Rights will state the method by which the
payment of the Redemption Price will be made.  The Company may, at its option,
pay the Redemption Price in cash, Common Shares (based upon the current per
share market price of the Common Shares (determined pursuant to Section 11(d))
at the time of redemption), or any other form of consideration deemed
appropriate by the Board of Directors of the Company (based upon the fair
market value of such other consideration, determined by the Board of Directors
of the Company in good faith) or any combination thereof.  The Company may, at
its option, combine the payment of the Redemption Price with any other payment
being made concurrently to holders of Common Shares and, to the extent that any
such other payment is discretionary, may reduce the amount thereof on account
of the concurrent payment of the Redemption Price.  If legal or contractual
restrictions prevent the Company from paying the Redemption Price (in the form
of consideration deemed appropriate by the Board of Directors) at the time of
redemption, the Company will pay the Redemption Price, without interest,
promptly after such time as the Company ceases to be so prevented from paying
the Redemption Price.

         24.     Exchange.  (a) The Board of Directors of the Company may, at
its option, at any time after the later of the Share Acquisition Date and the
Distribution Date, exchange all or part of the then-outstanding and exercisable
Rights (which will not include Rights that have become void pursuant to the
provisions of Section 11(a)(ii)) for Common Shares at an exchange ratio of one
Common Share per Right, appropriately adjusted to reflect any stock split,
stock dividend or similar transaction occurring after the Record Date (such
exchange ratio being hereinafter referred to as the "Exchange Ratio").  Any
such exchange will be effective immediately upon the action of the Board of
Directors of the Company ordering the same, unless such action of the Board of
Directors of the





                                      -35-
<PAGE>   39

Company expressly provides that such exchange will be effective at a subsequent
time or upon the occurrence or nonoccurrence of one or more specified events
(in which case such redemption will be effective in accordance with the
provisions of such action of the Board of Directors of the Company).
Notwithstanding the foregoing, the Board of Directors of the Company will not
be empowered to effect such exchange at any time after any Person (other than
the Company or any Related Person), who or which, together with all Affiliates
and Associates of such Person, becomes the Beneficial Owner of 50% or more of
the then-outstanding Common Shares.

         (b)     Immediately upon the effectiveness of the exchange of any
Rights as provided in Section 24(a), and without any further action and without
any notice, the right to exercise such Rights will terminate and the only right
with respect to such Rights thereafter of the holder of such Rights will be to
receive that number of Common Shares equal to the number of such Rights held by
such holder multiplied by the Exchange Ratio.  Promptly after the effectiveness
of the exchange of any Rights as provided in Section 24(a), the Company will
publicly announce such exchange and, within 10 calendar days thereafter, will
give notice of 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; provided,
however, that the failure to give, or any defect in, such notice will not
affect the validity of such exchange.  Any notice which is mailed in the manner
herein provided will 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 will 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)) held by each holder of Rights.

         (c)     In any exchange pursuant to this Section 24, the Company, at
its option, may substitute for any Common Share exchangeable for a Right (i)
equivalent common shares (as such term is used in Section 11(a)(iii)), (ii)
cash, (iii) debt securities of the Company, (iv) other assets, or (v) any
combination of the foregoing, in any event having an aggregate value, as
determined in good faith by the Board of Directors of the Company (whose
determination will be described in a statement filed with the Rights Agent),
equal to the current market value of one Common Share (determined pursuant to
Section 11(d)) on the Trading Day immediately preceding the date of the
effectiveness of the exchange pursuant to this Section 24.

         25.     Notice of Certain Events.  (a) If, after the Distribution
Date, the Company proposes (i) to pay any dividend payable in stock of any
class to the holders of Preferred Shares or to make any other distribution to
the holders of Preferred Shares (other than a regular periodic cash dividend),
(ii) to offer to the holders of Preferred Shares rights, options or warrants to
subscribe for or to





                                      -36-
<PAGE>   40

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
its 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 assets or earning power (including without limitation
securities creating any obligation on the part of the Company and/or any of its
Subsidiaries) representing more than 50% of the assets and earning power of the
Company and its Subsidiaries, taken as a whole, to any other Person or Persons
other than the Company or one or more of its wholly owned Subsidiaries, (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 reclassification of the Common Shares
then, in each such case, the Company will give to each holder of a Right
Certificate, to the extent feasible and in accordance with Section 26, a notice
of such proposed action, which specifies the record date for the purposes of
such stock dividend, distribution or offering of rights, options 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 will be so given, in
the case of any action covered by clause (i) or (ii) above, at least 10
calendar 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 calendar 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 is the earlier.

         (b)     In case any Triggering Event occurs, then, in any such case,
the Company will as soon as practicable thereafter give to the Rights Agent and
each holder of a Right Certificate, in accordance with Section 26, a notice of
the occurrence of such event, which specifies the event and the consequences of
the event to holders of Rights.

         26.     Notices.  (a) 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 will be sufficiently given or made if sent by
first class mail, postage prepaid, addressed (until another address is filed in
writing with the Rights Agent) as follows:

                                DTE Energy Company

                                      -37-
<PAGE>   41


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

                                The Detroit Edison Company
                                2000 2d Avenue
                                Detroit, Michigan 48226-1277
                                Attention: Vice President and General Counsel

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

         27.     Supplements and Amendments.  Prior to the time at which the
Rights cease to be redeemable pursuant to Section 23, and subject to the last
sentence of this Section 27, the Company may in its sole and absolute
discretion, and the Rights Agent will if the Company so directs, supplement or
amend any provision of this Agreement in any respect without the approval of
any holders of Rights or Common Shares.  From and after the time at which the
Rights cease to be redeemable pursuant to Section 23, and subject to the last
sentence of this Section 27, the Company may, and the Rights Agent will if the
Company so directs, supplement or amend this Agreement without the approval of
any holders of Rights or Common Shares in order (i) to cure any ambiguity, (ii)
to correct or supplement any provision contained herein which may be defective
or inconsistent with any other provisions herein, (iii) to shorten or lengthen
any time period hereunder, or (iv) to supplement or amend the provisions
hereunder in any manner which the Company may deem desirable; provided that no
such supplement or amendment shall adversely affect the interests of the
holders of Rights as such (other than an Acquiring Person or an Affiliate or
Associate of an Acquiring Person), and no such supplement or amendment shall
cause the Rights again to become redeemable or cause this Agreement again to
become supplementable or amendable otherwise than in accordance with the
provisions of this sentence.  Without limiting the generality or effect of the
foregoing, this Agreement may be supplemented or amended to provide for such
voting powers for the Rights and such procedures for the exercise thereof, if
any, as the Board of Directors of the Company may determine to be appropriate.
Upon the delivery of a certificate from an officer of the Company which states
that the proposed supplement or amendment is in compliance with the terms of
this Section 27, the Rights Agent will execute such supplement or amendment;
provided, however, that the failure or refusal of the Rights Agent to execute
such supplement or amendment will not affect the validity of any supplement or





                                      -38-
<PAGE>   42

amendment adopted by the Board of Directors of the Company, any of which will
be effective in accordance with the terms thereof.  Notwithstanding anything in
this Agreement to the contrary, no supplement or amendment may be made which
decreases the stated Redemption Price to an amount less than $0.01 per Right.

         28.     Successors; Certain Covenants.  All the covenants and
provisions of this Agreement by or for the benefit of the Company or the Rights
Agent will be binding on and inure to the benefit of their respective
successors and assigns hereunder.

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

         30.     Governing Law.  This Agreement, each Right and each Right
Certificate issued hereunder will be deemed to be a contract made under the
internal substantive laws of the State of Michigan and for all purposes will be
governed by and construed in accordance with the internal substantive laws of
such State applicable to contracts to be made and performed entirely within
such State.

         31.     Severability.  If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions of this Agreement will remain in full
force and effect and will in no way be affected, impaired or invalidated;
provided, however, that nothing contained in this Section 31 will affect the
ability of the Company under the provisions of Section 27 to supplement or
amend this Agreement to replace such invalid, void or unenforceable term,
provision, covenant or restriction with a legal, valid and enforceable term,
provision, covenant or restriction.

         32.     Descriptive Headings, Etc.  Descriptive headings of the
several Sections of this Agreement are inserted for convenience only and will
not control or affect the meaning or construction of any of the provisions
hereof.  Unless otherwise expressly provided, references herein to Articles,
Sections and Exhibits are to Articles, Sections and Exhibits of or to this
Agreement.

         33.     Determinations and Actions by the Board.  For all purposes of
this Agreement, any calculation of the number of Common Shares outstanding at
any particular time, including for purposes of determining the particular
percentage of such outstanding Common Shares of which any Person is the
Beneficial Owner, will be made in





                                      -39-
<PAGE>   43

accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules
and Regulations under the Exchange Act.  The Board of Directors of the Company
will have the exclusive power and authority to administer this Agreement and to
exercise all rights and powers specifically granted to the Board of Directors
of the Company or to the Company, or as may be necessary or advisable in the
administration of this Agreement, including without limitation the right and
power to (i) interpret the provisions of this Agreement and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including any determination as to whether particular Rights shall
have become void).  All such actions, calculations, interpretations and
determinations (including, for purposes of clause (y) below, any omission with
respect to any of the foregoing) which are done or made by the Board of
Directors of the Company in good faith will (x) be final, conclusive and
binding on the Company, the Rights Agent, the holders of the Rights and all
other parties and (y) not subject the Board of Directors of the Company to any
liability to any Person, including without limitation the Rights Agent and the
holders of the Rights.

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

                               DTE ENERGY COMPANY

                      (Pursuant to Section 450.1302 of the
               Business Corporation Act of the State of Michigan)


         DTE Energy Company, a Michigan corporation (the "Company"), DOES
HEREBY CERTIFY:

         That, pursuant to authority vested in the Board of Directors of the
Company by its Amended and Restated Articles of Incorporation, and pursuant to
the provisions of Section 450.1302 of the Michigan Business Corporation Act,
the Board of Directors of the Company has adopted the following resolution
providing for the issuance of a series of Preferred Stock:

         RESOLVED, that pursuant to the authority expressly granted to and
vested in the Board of Directors of the Company (hereinafter called the "Board
of Directors" or the "Board") by the Amended and Restated Articles of
Incorporation of the Company, a series of Preferred Stock, without par value
(the "Preferred Stock"), of the Company be, and it hereby is, created, and that
the designation and amount thereof and the powers, designations, preferences
and relative, participating, optional and other special rights of the shares of
such series, and the qualifications, limitations or restrictions thereof are as
follows:

                           I.  Designation and Amount

         The shares of such series will be designated as Series A Junior
Participating Preferred Stock (the "Series A Preferred") and the number of
shares constituting the Series A Preferred is 1,500,000.

                        II.  Dividends and Distributions

         (a)     Subject to the rights of the holders of any shares of any
series of Preferred Stock ranking prior to the Series A Preferred with respect
to dividends, the holders of shares of Series A Preferred, in preference to the
holders of Common Stock, without





                                      A-1
<PAGE>   46

par value (the "Common Stock"), of the Company, and of any other junior stock,
will be entitled to receive, when, as and if declared by the Board out of funds
legally available for the purpose, dividends payable in cash (except as
otherwise provided below) on such dates as are from time to time established
for the payment of dividends on the Common Stock (each such date being referred
to herein as a "Dividend Payment Date"), commencing on the first Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Preferred (the "First Dividend Payment Date"), in an amount per share
(rounded to the nearest cent) equal to the greater of (i) $1.00 or (ii) subject
to the provision for adjustment hereinafter set forth, one hundred times the
aggregate per share amount of all cash dividends, and one hundred times the
aggregate per share amount (payable in kind) of all non-cash dividends, 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 Dividend Payment Date or,
with respect to the First Dividend Payment Date, since the first issuance of
any share or fraction of a share of Series A Preferred.  In the event that the
Company at any time (i) declares a dividend on the outstanding shares of Common
Stock payable in shares of Common Stock, (ii) subdivides the outstanding shares
of Common Stock, (iii) combines the outstanding shares of Common Stock into a
smaller number of shares, or (iv) issues any shares of its capital stock in a
reclassification of the outstanding shares of Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such case
and regardless of whether any shares of Series A Preferred are then issued or
outstanding, the amount to which holders of shares of Series A Preferred would
otherwise be entitled immediately prior to such event under clause (ii) of the
preceding sentence will be adjusted by multiplying such amount by a fraction,
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

         (b)     The Company will declare a dividend on the Series A Preferred
as provided in the immediately preceding paragraph immediately after it
declares a dividend on the Common Stock (other than a dividend payable in
shares of Common Stock).  Each such dividend on the Series A Preferred will be
payable immediately prior to the time at which the related dividend on the
Common Stock is payable.

         (c)     Dividends will accrue on outstanding shares of Series A
Preferred from the Dividend Payment Date next preceding the date of issue of
such shares, unless (i) the date of issue of such shares is prior to the record
date for the First Dividend Payment Date, in which case dividends on such
shares will accrue from the date of the first issuance of a share of Series A
Preferred or (ii) the





                                      A-2
<PAGE>   47

date of issue is a Dividend Payment Date or is a date after the record date for
the determination of holders of shares of Series A Preferred entitled to
receive a dividend and before such Dividend Payment Date, in either of which
events such dividends will accrue from such Dividend Payment Date.  Accrued but
unpaid dividends will cumulate from the applicable Dividend Payment Date but
will not bear interest.  Dividends paid on the shares of Series A Preferred in
an amount less than the total amount of such dividends at the time accrued and
payable on such shares will be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding.  The Board may fix a record date
for the determination of holders of shares of Series A Preferred entitled to
receive payment of a dividend or distribution declared thereon, which record
date will be not more than 60 calendar days prior to the date fixed for the
payment thereof.

                              III.  Voting Rights

         The holders of shares of Series A Preferred will have the following
voting rights:

                 (a)      Subject to the provision for adjustment hereinafter
         set forth, each share of Series A Preferred will entitle the holder
         thereof to one vote on all matters submitted to a vote of the
         stockholders of the Company.

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

                 (c)      Except as set forth in the Amended and Restated
         Articles of Incorporation or herein, or as otherwise provided by law,
         holders of shares of Series A Preferred will have no voting rights.

                           IV.  Certain Restrictions

         (a)     Whenever dividends or other dividends or distributions payable
on the Series A Preferred are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Preferred outstanding have been paid in full, the Company will 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
         shares of Series A Preferred;





                                      A-3
<PAGE>   48

                  (ii)    Declare or pay dividends, or make any other
         distributions, on any shares of stock ranking on a parity (either as
         to dividends or upon liquidation, dissolution, or winding up) with the
         shares of Series A Preferred, except dividends paid ratably on the
         shares of Series A Preferred 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, 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
         shares of Series A Preferred; provided, however, that the Company may
         at any time redeem, purchase or otherwise acquire shares of any such
         junior stock in exchange for shares of any stock of the Company
         ranking junior (either as to dividends or upon dissolution,
         liquidation or winding up) to the shares of Series A Preferred; or

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

         (b)     The Company will not permit any majority-owned subsidiary of
the Company to purchase or otherwise acquire for consideration any shares of
stock of the Company unless the Company could, under paragraph (a) of this
Article IV, purchase or otherwise acquire such shares at such time and in such
manner.

                             V.  Reacquired Shares

         Any shares of Series A Preferred purchased or otherwise acquired by
the Company in any manner whatsoever will be retired and canceled promptly
after the acquisition thereof.  All such shares will 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 Amended and Restated Articles
of Incorporation of the Company, or in any other Preferred Stock Designation
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.





                                      A-4
<PAGE>   49

                  VI.  Liquidation, Dissolution or Winding Up

         Upon any liquidation, dissolution or winding up of the Company, no
distribution will be made (a) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution, or winding up) to the
shares of Series A Preferred unless, prior thereto, the holders of shares of
Series A Preferred 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, however, that the holders of
shares of Series A Preferred will be entitled to receive an aggregate amount
per share, subject to the provision for adjustment hereinafter set forth, equal
to one hundred times the aggregate amount to be distributed per share to
holders of shares of Common Stock or (b) to the holders of shares of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution,
or winding up) with the shares of Series A Preferred, except distributions made
ratably on the shares of Series A Preferred and all such parity stock in
proportion to the total amounts to which the holders of all such shares are
entitled upon such liquidation, dissolution, or winding up.  In the event the
Company at any time (i) declares a dividend on the outstanding shares of Common
Stock payable in shares of Common Stock, (ii) subdivides the outstanding shares
of Common Stock, (iii) combines the outstanding shares of Common Stock into a
smaller number of shares, or (iv) issues any shares of its capital stock in a
reclassification of the outstanding shares of Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such case
and regardless of whether any shares of Series A Preferred are then issued or
outstanding, the aggregate amount to which each holder of shares of Series A
Preferred would otherwise be entitled immediately prior to such event under the
proviso in clause (a) of the preceding sentence will 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.

                       VII.  Consolidation, Merger, Etc.

         In the event that the Company enters 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 each such case, each share of Series A Preferred will at the
same time be similarly exchanged for or changed into an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to one
hundred times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged.  In the event the Company at any
time (a) declares a dividend on the outstanding shares of Common Stock





                                      A-5
<PAGE>   50

payable in shares of Common Stock, (b) subdivides the outstanding shares of
Common Stock, (c) combines the outstanding shares of Common Stock in a smaller
number of shares, or (d) issues any shares of its capital stock in a
reclassification of the outstanding shares of Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such case
and regardless of whether any shares of Series A Preferred are then issued or
outstanding, the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred will 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.

                               VIII.  Redemption

         The shares of Series A Preferred are not redeemable.

                                   IX.  Rank

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

                                 X.  Amendment

         Notwithstanding anything contained in the Amended and Restated
Articles of Incorporation of the Company to the contrary and in addition to any
other vote required by applicable law, the Amended and Restated Articles of
Incorporation of the Company may not be amended in any manner that would
materially alter or change the powers, preferences or special rights of the
Series A Preferred so as to affect them adversely without the affirmative vote
of the holders of at least 80% of the outstanding shares of Series A Preferred,
voting together as a single series.

         IN WITNESS WHEREOF, this Certificate of Designation is executed on
behalf of the Company by its Chairman and Chief Executive Officer and attested
by its Vice President and Secretary this 23rd day of September, 1997.

         This certifies that _______________, or registered assigns, is the
registered owner of the number of Rights set forth above, each of which
entitles the owner thereof, subject to the terms, provisions, and conditions of
the Rights Agreement, dated as of September 23, 1997 (the "Rights Agreement"),

Right Certificate with the Form of Election to Purchase and related Certificate
duly executed.  If this Right Certificate is exercised in part, the holder will
be entitled to receive upon surrender hereof another Right Certificate or Right
Certificates for the number of whole Rights not exercised.  The number of
Rights evidenced by this Right Certificate (and the number of one

                                      B-1
<PAGE>   53

         As provided in the Rights Agreement, the Purchase Price and/or the
number and/or kind of securities issuable upon the exercise of the Rights
evidenced by this Right Certificate are subject to adjustment upon the
occurrence of certain events.

         This Right Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities of the Rights Agent,
the Company and the holders of the Right Certificates, which limitations of
rights include the temporary suspension of the exercisability of the Rights
under the circumstances specified in the Rights Agreement.  Copies of the
Rights Agreement are on file at the above-mentioned office of the Rights Agent
and can be obtained from the Company without charge upon written request
therefor.  Terms used herein with initial capital letters and not defined
herein are used herein with the meanings ascribed thereto in the Rights
Agreement.

         Pursuant to the Rights Agreement, from and after the occurrence of a
Flip-in Event, any Rights that are Beneficially Owned by (i) any Acquiring
Person (or any Affiliate or Associate of any Acquiring Person), (ii) a
transferee of any Acquiring Person (or any such Affiliate or Associate) who
becomes a transferee after the occurrence of a Flip-in Event, or (iii) a
transferee of any Acquiring Person (or any such Affiliate or Associate) who
became a transferee prior to or concurrently with the Flip-in Event pursuant to
either (a) a transfer from an Acquiring Person to holders of its equity
securities or to any Person with whom it has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (b) a transfer
which the Board of Directors of the Company has determined is part of a plan,
arrangement or understanding which has the purpose or effect of avoiding
certain provisions of the Rights Agreement, and subsequent transferees of any
of such Persons, will be void without any further action and any holder of such
Rights will thereafter have no rights whatsoever with respect to such Rights
under any provision of the Rights Agreement.  From and after the occurrence of
a Flip-in Event, no Right Certificate will be issued that represents Rights
that are or have become void pursuant to the provisions of the Rights
Agreement, and any Right Certificate delivered to the Rights Agent that
represents Rights that are or have become void pursuant to the provisions of
the Rights Agreement will be canceled.

         This Right Certificate, with or without other Right Certificates, may
be transferred, split up, combined or exchanged for another Right Certificate
or Right Certificates entitling the holder to purchase a like number of one
one-hundredths of a Preferred Share (or other securities, as the case may be)
as the Right Certificate or Right Certificates surrendered entitled such holder
(or former holder in the case of a transfer) to purchase,





                                      B-2
<PAGE>   54

upon presentation and surrender hereof at the principal office of the Rights
Agent designated for such purpose, with the Form of Assignment (if appropriate)
and the related Certificate duly executed.

         Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company at its option at a
redemption price of $.01 per Right or may be exchanged in whole or in part.
The Rights Agreement may be supplemented and amended by the Company, as
provided therein.

         The Company is not required to issue fractions of Preferred Shares
(other than fractions which are integral multiples of one one- hundredth of a
Preferred Share, which may, at the option of the Company, be evidenced by
depositary receipts) or other securities issuable upon the exercise of any
Right or Rights evidenced hereby.  In lieu of issuing such fractional Preferred
Shares or other securities, the Company may make a cash payment, as provided in
the Rights Agreement.

         No holder of this Right Certificate, as such, will be entitled to vote
or receive dividends or be deemed for any purpose the holder of the Preferred
Shares or of any other securities of the Company which may at any time be
issuable upon the exercise of the Right or Rights represented hereby, nor will
anything contained herein or in the Rights Agreement be construed to confer
upon the holder hereof, as such, any of the rights of a stockholder of the
Company or any right to vote for the election of directors or upon any matter
submitted to stockholders at any meeting thereof, or to give or withhold
consent to any corporate action, or to receive notice of meetings or other
actions affecting stockholders (except as provided in the Rights Agreement), or
to receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by this Right Certificate have been exercised in accordance

                 SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK

         The Board of Directors (the "Board") of DTE Energy Company, a Michigan
corporation (the "Company"), has declared a dividend distribution of one right
(a "Right") for each outstanding share of Common Stock, without par value (the
"Common Shares"), of the Company.  The distribution is payable on October 6,
1997 the "Record Date") to the stockholders of record as of the close of
business on the Record Date.  Each Right entitles the registered holder thereof
to purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock, without par value (the "Preferred Shares"), of
the Company at a price (the "Purchase Price") of $90.00 per one one-hundredth
of a Preferred Share, subject to adjustment.  The description and terms of the
Rights are set forth in a Rights Agreement, dated as of September 23, 1997 (the
"Rights Agreement"), between the Company and The Detroit Edison Company, as
Rights Agent (the "Rights Agent").

         Under the Rights Agreement, the Rights will be evidenced by the
certificates evidencing Common Shares until the earlier (the "Distribution
Date") of:  (i) the close of business on the tenth calendar day (or such later
date as may be specified by the Board) following the first date (the "Share
Acquisition Date") of public announcement that a person (other than the
Company, a subsidiary or employee benefit or stock ownership plan of the
Company or any of its affiliates or associates), together with its affiliates
and associates, has acquired beneficial ownership of 10% or more of the
outstanding Common Shares (any such person being hereinafter called an
"Acquiring Person") or (ii) the close of business on the tenth business day (or
such later date as may be specified by the Board) following the commencement of
a tender offer or exchange offer by a person (other than the Company, a
subsidiary or employee benefit or stock ownership plan of the Company or any of
its affiliates or associates), the consummation of which would result in
beneficial ownership by such person 10% or more of the outstanding Common
Shares.

         The Rights Agreement provides that, until the Distribution Date, the
Rights may be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), any
certificate evidencing Common Shares of the Company issued upon transfer or new
issuance of the Common Shares will contain a notation incorporating the Rights
Agreement by reference.  Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any certificates
evidencing Common Shares will also constitute the transfer of the Rights
associated with such certificates.  As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of Common Shares as of the
close of business on the Distribution Date and such separate Rights
Certificates alone will evidence the Rights.  No Right is exercisable at any
time prior to the Distribution Date.  The





                                      C-1

Rights will expire on the tenth anniversary of the Record Date (the "Final
Expiration Date") unless earlier redeemed, exchanged or amended by the Company
as described below.  Until a Right is exercised, the holder thereof, as such,
will have no rights as a stockholder of the Company, including the right to
vote or to receive dividends.

         The Purchase Price payable, and the number of the Preferred Shares or
other securities issuable, upon exercise of the Rights will be subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares, (ii) upon the grant to holders of Preferred Shares of certain
rights or warrants to subscribe for or purchase the Preferred Shares at a
price, or securities convertible into the Preferred Shares with a conversion
price, less than the then-current market price of the Preferred Shares, or
(iii) upon the distribution to holders of the Preferred Shares of evidences of
indebtedness, cash (excluding regular periodic cash dividends), assets, stock
(excluding dividends payable in the Preferred Shares) or subscription rights or
warrants (other than those referred to above).  The number of outstanding
Rights and the number of one one-hundredths of the Preferred Shares issuable
upon exercise of each Right will be subject to adjustment in the event of a
stock dividend on the Common Shares payable in Common Shares or a subdivision,
combination or reclassification of Common Shares occurring, in any such case,
prior to the Distribution Date.

         The Preferred Shares issuable upon exercise of the Rights will not be
redeemable.  Each Preferred Share will be entitled, in connection with the
declaration of a dividend on the Common Shares, to a preferential dividend
payment equal to the greater of (i) $1.00 per share and (ii) an amount equal to
100 times the related dividend declared per Common Share.  Subject to customary
anti-dilution provisions, in the event of liquidation, the holders of Preferred
Shares will be entitled to a preferential liquidation payment equal to the
greater of (a) $100 per share and (b) an amount equal to 100 times the
liquidation payment made per Common Share.  Because of the nature of the
Preferred Shares' dividend and liquidation rights, the value of the one
one-hundredth interest in a Preferred Share purchasable upon exercise of a
Right should approximate the value of one Common Share.

         Rights will be exercisable to purchase Preferred Shares only after the
Distribution Date occurs and prior to the occurrence of a Flip-in Event as
described below.  A Distribution Date resulting from the commencement of a
tender offer or exchange offer described in clause (ii) of the second paragraph
of this summary could precede the occurrence of a Flip-in Event and thus result
in the Rights being exercisable to purchase Preferred Shares.  A Distribution
Date resulting from any occurrence described in clause (i) of the second
paragraph of this summary would necessarily follow the occurrence of a Flip-in
Event and thus result in the





                                      C-2
<PAGE>   62

Rights being exercisable to purchase Common Shares or other securities as
described below.

         Under the Rights Agreement, in the event (a "Flip-in Event") that (i)
any person, together with its affiliates and associates, becomes the beneficial
owner of 10% or more of the outstanding Common Shares, (ii) any Acquiring
Person or any affiliate or associate thereof merges into or combines with the
Company and the Company is the surviving corporation, (iii) any Acquiring
Person or any affiliate or associate thereof effects certain other transactions
with the Company, or (iv) during such time as there is an Acquiring Person the
Company effects certain transactions, in each case as described in the Rights
Agreement, then, in each such case, proper provision will be made so that from
and after the latest of the Share Acquisition Date, the Distribution Date and
the date of the occurrence of such Flip-in Event each holder of a Right, other
than Rights that are or were owned beneficially by an Acquiring Person (which,
from and after the date of a Flip-in Event, will be void), will have the right
to receive, upon exercise thereof at the then-current exercise price of the
Right, that number of Common Shares (or, under certain circumstances, an
economically equivalent security or securities of the Company) that at the time
of such Flip-in Event have a market value of two times the exercise price of
the Right.

         In the event (a "Flip-over Event") that, at any time after a person
has become an Acquiring Person, (i) the Company merges with or into any person
and the Company is not the surviving corporation, (ii) any person merges with
or into the Company and the Company is the surviving corporation, but all or
part of the Common Shares are changed or exchanged for stock or other
securities of any other person or cash or any other property, or (iii) 50% or
more of the Company's assets or earning power, including securities creating
obligations of the Company, are sold, in each case as described in the Rights
Agreement, then, in each such case, proper provision will be made so that from
and after the later of the Distribution Date and the date of the occurrence of
such Flip-over Event each holder of a Right, other than Rights which have
become void, will have the right to receive, upon the exercise thereof at the
then-current exercise price of the Right, that number of shares of common stock
(or, under certain circumstances, an economically equivalent security or
securities) of such other person that at the time of such Flip-over Event have
a market value of two times the exercise price of the Right.

         From and after the later of the Share Acquisition Date and the
Distribution Date, Rights (other than any Rights that have become void) will be
exercisable as described above, upon payment of the aggregate exercise price in
cash.  In addition, at any time after the later of the Share Acquisition Date
and the Distribution Date and prior to the acquisition by any person or group
of affiliated or associated persons of 50% or more of the outstanding Common
Shares, the Company may exchange the Rights (other than any rights





                                      C-3
<PAGE>   63

that have become void), in whole or in part, at an exchange ratio of one Common
Share per Right (subject to adjustment).

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment in the Purchase
Price of at least 1%.  The Company will not be required to issue fractional
Preferred Shares (other than fractions that are integral multiples of one
one-hundredth of a Preferred Share, which may, at the option of the Company, be
evidenced by depositary receipts) or fractional Common Shares or other
securities issuable upon the exercise of Rights.  In lieu of issuing such
securities, the Company may make a cash payment, as provided in the Rights
Agreement.

         The Company may, at its option, redeem the Rights in whole, but not in
part, at a price of $.01 per Right, subject to adjustment (the "Redemption
Price"), at any time prior to the close of business on the later of (i) the
date of the first occurrence of any Flip-in Event or Flip-over Event and (ii)
the Distribution Date.  Immediately upon any redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders
of Rights will be to receive the Redemption Price.

         The Rights Agreement may be amended by the Company without the
approval of any holders of Rights Certificates, including amendments that
increase or decrease the Purchase Price, that add other events requiring
adjustment to the Purchase Price payable and the number of the Preferred Shares
or other securities issuable upon the exercise of the Rights or that modify
procedures relating to the redemption of the Rights, except that no amendment
may be made that decreases the stated Redemption Price to an amount less than
$.01 per Right.

         The Board will have the exclusive power and authority to administer
the Rights Agreement and to exercise all rights and powers specifically granted
to the Board or to the Company therein, or as may be necessary or advisable in
the administration of the Rights Agreement, including without limitation the
right and power to interpret the provisions of the Rights Agreement and to make
all determinations deemed necessary or advisable for the administration of the
Rights Agreement (including any determination to redeem or not redeem the
Rights or to amend or not amend the Rights Agreement).  All such actions,
calculations, interpretations and determinations (including any omission with
respect to any of the foregoing) which are done or made by the Board in good
faith will be final, conclusive and binding on the Company, the Rights Agent,
the holders of the Rights and all other parties and will not subject the Board
to any liability to any person, including without limitation the Rights Agent
and the holders of the Rights.

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an exhibit to a Registration

                              [COMPANY LETTERHEAD]


                                October 6, 1997



To Our Stockholders:

         We are pleased to inform you that DTE Energy Company has adopted a new
stockholder rights plan.

         This action was taken after long and careful study and was not taken
in response to any pending takeover or proposed change in control of the
Company.  The plan is intended to protect the Company and its stockholders from
potentially coercive takeover practices or takeover bids which are inconsistent
with the interests of the Company and its stockholders.  The plan is not
intended to deter unsolicited offers that would provide superior long-term
value to all of the Company's stockholders.  The adoption of a stockholder
rights plan has become common practice in major American companies and a well
accepted approach to ensuring that all stockholders receive a fair price and
are treated equally in the event of a takeover.

         To effect the plan, the Board of Directors declared a dividend of one
stockholder right for each outstanding share of the Company's common stock.
The distribution is being made to stockholders of record as of the close of
business today.

         Under the plan, the rights will initially trade together with the
Company's common stock and will not be exercisable.  In the absence of further
board action, the rights generally will become exercisable and allow the holder
to acquire the Company's common stock at a discounted price if a person or
group acquires 10 percent or more of the Company's common stock.  Rights held
by persons who exceed the applicable threshold will be void.  Under certain
circumstances, the rights will entitle the holder to buy shares in an acquiring
entity at a discounted price.

         The plan also includes an exchange option.  In general, after the
rights become exercisable, the Board of Directors may, at its option, effect an
exchange of part or all of the rights (other than rights that have become void)
for shares of the Company's common stock.  Under this option, the Company would
issue one share of common stock for each right, subject to adjustment in
certain circumstances.

         The Company's Board of Directors may, at its option, redeem all rights
for $.01 per right, generally at any time prior to the rights becoming
exercisable.  The rights will expire September 23, 2007, unless earlier
redeemed, exchanged or amended by the Board of Directors.





<PAGE>   2

         The issuance of the rights is not a taxable event, will not affect the
Company's reported financial condition or results of operations (including
earnings per share), should not interfere with the Company's operating,
financing or investing activities and will not change the way in which the
Company's common stock is currently traded.

         A summary of the stockholder rights plan (which explains the terms and
nature of the rights) is enclosed.  Stockholders are urged to review the
summary carefully and retain it with their permanent records.

         In adopting the stockholder rights plan, the Board has expressed its
confidence in the Company's future and its determination that you, our
stockholders, be given every opportunity to participate fully in that future.

On Behalf of the Board of Directors,



John E. Lobbia
Chairman of the Board and
Chief Executive Officer

DTE ENERGY COMPANY BOARD ADOPTS SHAREHOLDER RIGHTS PLAN
- -------------------------------------------------------

        DETROIT - The Board of Directors of DTE Energy Company (NYSE/CSE: DTE),
parent of Detroit Edison, today announced the adoption of a new shareholders
rights plan for stockholders of record on Oct. 6, 1997.

        "This action was taken after long and careful consideration," said John
E. Lobbia, DTE Energy chairman and chief executive officer.  "While the plan is
not in response to any pending takeover or proposed change in the control of
the company, it is clearly intended to protect the company and its shareholders
from any potentially coercive takeover practices or bids that would not benefit
DTE Energy and our shareholders."
        
        Share purchase rights plans have become common practice in major
American companies and ensure that all shareholders receive a fair price and
are treated equally in the event of a takeover, Lobbia said.

        Under the plan, one right will be issued for each common share
outstanding on the record date.  Initially the DTE Energy plan calls for the
rights to trade together with DTE Energy common stock.  The rights will not be
exercisable immediately.  However in the absence of further board action, the
rights generally will become exercisable if any person or group acquires 10
percent or more of the outstanding common shares of DTE Energy.  This will
entitle shareholders, other than that person or group, to buy DTE Energy common
stock at a discount.  Under certain circumstances, the plan allows DTE
Energy shareholders the right to buy shares in an acquiring entity at a
discount.

                                    -more-
        
<PAGE>   2
                                     -2-


        The plan includes an option that allows the board of directors to
exchange for common stock all or part of the exercisable rights of shareholders
other than the person or group holding 10 percent or more of DTE Energy common
stock.  Under this option, DTE Energy  typically would issue one share of
common stock for each right.  The number of shares issued in an exchange is
subject to adjustment under the plan.

        The plan includes an option generally allowing the DTE Energy Board of
Directors to redeem all rights for one cent per right at any time before the
rights are exercisable.  Unless redeemed, exchanged or amended by the board of
directors, the rights will expire Oct. 6, 2007.

        This action will not change the way DTE Energy common stock is traded
currently.  Issuing the rights will not affect DTE Energy's reported financial
condition or results of operations, including earnings per share.  In addition,
shareholders will not be subject to federal income tax on the issuance of the
rights.

        DTE Energy Company is a Detroit-based diversified energy company
involved in the development and management of energy-related businesses and
services nationwide.  It also is the parent company of Detroit Edison, an
electric utility that serves 2 million customers in Southeastern Michigan.
