         Item 5. Other Events.

         On April 27, 2000, the Board of Directors of the Registrant (the
"Board") authorized the amendment and restatement of the Rights Agreement dated
as of May 4, 1990, between the Registrant and NBD Bank, N.A., as rights agent
(the "Original Rights Agreement"), resulting in an Amended and Restated Rights
Agreement, dated as of April 27, 2000 (the "Amended Rights Agreement"), between
the Registrant and State Street Bank & Trust Company, as rights agent.

         The Amended Rights Agreement was adopted in the normal course of
updating and extending the Original Rights Agreement which was scheduled to
expire on May 4, 2000, and not in response to any acquisition proposal.

         In the Amended Rights Agreement, the Registrant has extended the
expiration date of its rights plan to May 4, 2010, and has amended it to reflect
prevailing stockholder rights plan terms. These amendments include, without
limitation, the following: (a) amending the definition of Acquiring Person to
prevent inadvertent triggering of the rights plan and (b) providing for a
cashless exchange of the rights, at the option of the Board of Directors of the
Registrant. In addition, the Registrant also appointed State Street Bank & Trust
Company as a successor rights agent.

         A copy of the Amended Rights Agreement is attached hereto as Exhibit 4
and is incorporated herein by reference. The foregoing discussion does not
purport to be complete and is qualified in its entirety by reference to such
Exhibit.

         Item 7.     Exhibits.

        Exhibit 4    Amended and Restated Rights Agreement dated as of April 27,
                     2000, between the Registrant and State Street Bank & Trust
                     Company, as rights agent.

        Exhibit 99   Press Release, dated April 27, 2000.

                      AMENDED AND RESTATED RIGHTS AGREEMENT


                  AMENDED AND RESTATED RIGHTS AGREEMENT, dated as of April 27,
2000 (the "Agreement"), between Detrex Corporation, a Michigan corporation (the
"Company"), and State Street Bank & Trust Company, a Massachusetts Trust Company
(the "Rights Agent").

                  WHEREAS, on May 4, 1990 (the "Rights Dividend Declaration
Date"), the Board of Directors of the Company authorized and declared a
distribution of one Right for each share of common stock, par value $2.00 per
share, of the Company (the "Company Common Stock") outstanding at the Close of
Business on May 15, 1990 (the "Record Date"), and issued one Right (as such
number may hereinafter be adjusted pursuant hereto) for each share of Company
Common Stock issued between the Record Date (whether originally issued or
delivered from the Company's treasury) and, except as otherwise provided in
Section 22, the Distribution Date, each Right initially representing the right
to purchase upon the terms and subject to the conditions hereinafter set forth
one Unit of Series A Preferred Stock (the "Rights");

                  WHEREAS, the Board of Directors has authorized amending the
Rights Agreement, dated as of May 4, 1990, between the Company and NBD Bank,
N.A., which amendment will, among other things, extend the Final Expiration Date
(as defined below) and change the Rights Agent; and

                  WHEREAS, the Company desires to set forth certain terms and
conditions governing the Rights;

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

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

                  (a) "Acquiring Person" shall mean any Person who or which,
         alone or together with all Affiliates and Associates of such Person,
         shall be the Beneficial Owner of 15% or more of the shares of Company
         Common Stock then outstanding, but shall not include (x) the Company,
         any Subsidiary of the Company, any employee benefit plan maintained by
         the Company or any of its Subsidiaries or any trustee or fiduciary with
         respect to such plan acting in such capacity or (y) any such Person who
         has become and is such a Beneficial Owner solely because (A) of a
         change in the aggregate number of shares of the Company Common Stock
         since the last date on which such Person acquired Beneficial Ownership
         of any shares of the Company Common Stock or (B) it acquired such
         Beneficial Ownership in the good faith belief that such acquisition
         would not (1) cause such Beneficial Ownership to be equal to or exceed
         15% of the shares of the Company Common Stock then outstanding and such
         Person relied in good faith in computing the percentage of its
         Beneficial Ownership on publicly filed reports or documents of the
         Company that are inaccurate or out-of-date or (2) otherwise cause a
         Distribution Date or the adjustment provided for in Section 11(a)(ii)
         to occur. Notwithstanding clause (B) of the prior sentence, if any
         Person that is not an Acquiring Person due to such clause (B) does not
         reduce its percentage of Beneficial


<PAGE>   4


                                        2

         Ownership of the Company Common Stock to less than 15% by the Close of
         Business on the fifth Business Day after notice from the Company (the
         date of notice being the first day) that such person's Beneficial
         Ownership of the Company Common Stock so equals to or exceeds 15%, such
         Person shall at the end of such five Business Day period, become an
         Acquiring Person (and such clause(B) shall no longer apply to such
         Person). For purposes of this definition, the determination whether any
         Person acted in "good faith" shall be conclusively determined by the
         Board of Directors of the Company, acting by a vote of those directors
         of the Company whose approval would be required to redeem the Rights
         under Section 23.

                  (b) "Adjustment Shares" has the meaning set forth in Section
         11(a)(ii).

                  (c) "Adjustment Spread" has the meaning set forth in Section
         34(a)(ii).

                  (d) "Affiliate" and "Associate" shall have the respective
         meanings ascribed to such terms in Rule 12b-2 of the General Rules and
         Regulations under the Securities Exchange Act of 1934, as amended (the
         "Exchange Act"), as in effect on the date hereof.

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

                      (i)   of which such Person or any of such Person's
                  Affiliates or Associates is considered to be a "beneficial
                  owner" under Rule 13d-3 of the General Rules and Regulations
                  under the Exchange Act (the "Exchange Act Regulations") as in
                  effect on the date hereof; provided, however, that a Person
                  shall not be deemed the "Beneficial Owner" of, or to
                  "beneficially own", or to have "Beneficial Ownership" of, any
                  securities under this subparagraph (i) as a result of an
                  agreement, arrangement or understanding to vote such
                  securities if such agreement, arrangement or understanding (A)
                  arises solely from a revocable proxy given in response to a
                  proxy or consent solicitation made pursuant to, and in
                  accordance with, the applicable provisions of the Exchange Act
                  and the Exchange Act Regulations, and (B) is not reportable by
                  such Person on Schedule 13D under the Exchange Act (or any
                  comparable or successor report);

                      (ii)  which are beneficially owned, directly or
                  indirectly, by any other Person (or any Affiliate or Associate
                  of such other Person) with which such Person (or any of such
                  Person's Affiliates or Associates) has any agreement,
                  arrangement or understanding (whether or not in writing), for
                  the purpose of acquiring, holding, voting (except pursuant to
                  a revocable proxy as described in the proviso to subparagraph
                  (i) of this paragraph (c)) or disposing of such securities; or

                      (iii) 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 or upon the
                  satisfaction of

                  of conversion rights, exchange rights, rights, warrants or
                  options, or otherwise;

         provided, however, that under this paragraph (e) a Person shall not be
         deemed the "Beneficial Owner" of, or to "beneficially own", or to have
         "Beneficial Ownership" of, (A) securities tendered pursuant to a tender
         or exchange offer made in accordance with Exchange Act Regulations by
         such Person or any of such Person's Affiliates or Associates until such
         tendered securities are accepted for purchase or exchange, (B)
         securities that may be issued upon exercise of Rights at any time prior
         to the occurrence of a Triggering Event, or (C) securities that may be
         issued upon exercise of Rights from and after the occurrence of a

         date is not a Business Day it shall mean 5:00 P.M., New York City time,
         on the next succeeding Business Day.

                  (h) "Common Stock" of any Person other than the Company shall
         mean the capital stock of such Person with the greatest voting power,

         Exchange Act) by the Company or an Acquiring Person that an Acquiring
         Person has become such.

                  (ff)  "Subsidiary" shall mean, with reference to any Person,
         any other Person of which an amount of voting securities or equity
         interests sufficient to elect at least a majority of the directors or
         equivalent governing body of such other Person is beneficially owned,
         directly or indirectly, by such Person, or otherwise controlled by such
         first-mentioned Person.

                  SECTION 2. Appointment of Rights Agent. The Company hereby
appoints the Rights Agent to act as agent for the Company in accordance with the

appointment. With the consent of the Rights Agent, the Company may from time to

ten (10) days' prior written notice to the Rights Agent. The Rights Agent shall
have no duty to supervise, and shall in no event be liable for, the acts or
omissions of any such Co-Rights Agent.

                  SECTION 3. Issue of Rights Certificates. (a) Until the earlier
of (i) the Close of Business on the tenth Business Day after the Stock
Acquisition Date, and (ii) the Close of Business on the tenth Business Day (or
such later date as may be determined by action of the Company's Board of
Directors prior to such time as any Person becomes an Acquiring Person and of
which the Company will give the Rights Agent prompt written notice) after the
date that a tender or exchange offer by any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan maintained by the Company
or any of its Subsidiaries or any trustee or fiduciary with respect to such plan
acting in such capacity) is first published or sent or given within the meaning
of Rule 14d-4(a) of the Exchange Act Regulations or any successor rule, if upon
consummation thereof such Person would be the Beneficial Owner of 30% or more of
the shares of Company Common Stock then outstanding (the earlier of (i) and (ii)
above being the "Distribution Date"), (x) the Rights will be evidenced (subject
to the provisions of paragraph (b) of this Section 3) by the certificates for
shares of Company Common Stock registered in the names of the holders of shares
of Company Common Stock as of and subsequent to the Record Date (which
certificates for shares of Company Common Stock shall be deemed also to be
certificates for Rights) and not by separate certificates, and (y) the Rights
will be transferable only in connection with the transfer of the underlying
shares of Company Common Stock (including a transfer to the Company). As soon as
practicable after the Distribution Date, the Rights Agent will send by first
class, insured, postage prepaid mail, to each record holder of shares of Company
Common Stock as of the Close of Business on the Distribution Date, at the
address of such holder shown on the records of the Company, one or more rights
certificates, in


<PAGE>   8


                                        6

substantially the form of Exhibit A hereto (the "Rights Certificates"),
evidencing one Right for each share of Company Common Stock so held, subject to
adjustment as provided herein. In the event that an adjustment in the number of
Rights per share of Company Common Stock has been made pursuant to Section 11(p)
hereof, at the time of distribution of the Rights Certificates, the Company may
make the necessary and appropriate rounding adjustments (in accordance with
Section 14(a) hereof) so that Rights Certificates representing only whole
numbers of Rights are distributed and cash is paid in lieu of any fractional
Rights. As of and after the Distribution Date, the Rights will be evidenced
solely by such Rights Certificates.

                  (b) As promptly as practicable following the Record Date, the
Company sent a copy of a Summary of Rights to Purchase Preferred Stock, in a
form which may be appended to certificates that represent shares of Company
Common Stock, in substantially the form attached hereto as Exhibit B (the
"Summary of Rights") (Exhibit B having been amended, however, to summarize the
terms of the Rights, as amended on the date hereof), by first-class, postage
prepaid mail, to each record holder of shares of Company Common Stock as of the
Close of Business on the Record Date, at the address of such holder shown on the
records of the Company.

                  (c) Rights shall, without any further action, be issued in
respect of all shares of Company Common Stock which are issued (including any
shares of Company Common Stock held in treasury) after the Record Date but prior
to the earlier of the Distribution Date and the Expiration Date. Certificates,
representing such shares of Company Common Stock, issued after the Record Date
shall bear the following legend:

                  "This certificate also evidences and entitles the holder
         hereof to certain Rights as set forth in the Rights Agreement between
         Detrex Corporation (the "Company") and NBD Bank, N.A. (the "Rights
         Agent") dated as of May 4, 1990 (the "Rights Agreement"), the terms of
         which are hereby incorporated herein by reference and a copy of which
         is on file at the principal office of the stock transfer administration
         office of the Rights Agent. Under certain circumstances, as set forth
         in the Rights Agreement, such Rights will be evidenced by separate
         certificates and will no longer be evidenced by this certificate. The
         Company will mail to the holder of this certificate a copy of the
         Rights Agreement, as in effect on the date of mailing, without charge
         promptly after receipt of a written request therefor. Under certain
         circumstances set forth in the Rights Agreement, Rights issued to, or
         held by, any Person who is, was or becomes an Acquiring Person or any
         Affiliate or Associate thereof (as such terms are defined in the Rights
         Agreement), whether currently held by or on behalf of such Person or by
         any subsequent holder, may become null and void."

; provided, however, that with respect to certificates representing such shares
of Company Common Stock which are issued (including any share of Company Common
Stock held in treasury) after the date hereof but prior to the earlier of the
Distribution Date and the Expiration Date, the first sentence of such legend
shall be replaced with the following:



<PAGE>   9


                                        7

                  "This certificate also evidences and entitles the holder
         hereof to certain Rights as set forth in the Amended and Restated
         Rights Agreement between Detrex Corporation (the "Company") and State
         Street Bank & Trust Company (the "Rights Agent") dated as of April 27,
         2000 (the "Rights Agreement"), the terms of which are hereby
         incorporated herein by reference and a copy of which is on file at the
         principal office of the stock transfer administration office of the
         Rights Agent."

With respect to certificates representing shares of Company Common Stock
(whether or not such certificates include the foregoing legend or have appended
to them the Summary of Rights), until the earlier of the Distribution Date and
the Expiration Date, the Rights associated with the shares of Company Common
Stock represented by such certificates shall be evidenced by such certificates
alone and registered holders of the shares of Company Common Stock shall also be
the registered holders of the associated Rights, and the transfer of any of such
certificates shall also constitute the transfer of the Rights associated with
the shares of Company Common Stock represented by such certificates.

                  SECTION 4. Form of Rights Certificates. (a) The Rights
Certificates (and the forms of election to purchase, assignment and certificate
to be printed on the reverse thereof) shall each be substantially in the form
set forth in Exhibit A hereto and may have such marks of identification or
designation and such legends, summaries or endorsements printed thereon as the
Company may deem appropriate and as are not inconsistent with the provisions of
this Agreement, or as may be required to comply with any applicable law or any
rule or regulation thereunder or with any rule or regulation of any stock
exchange on which the Rights may from time to time be listed or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever distributed, shall be dated as of the Record Date and on
their face shall entitle the holders thereof to purchase such number of Units of
Preferred Stock as shall be set forth therein at the price set forth therein,
but the amount and type of securities, cash or other assets that may be acquired
upon the exercise of each Right and the Purchase Price thereof shall be subject
to adjustment as provided herein.

                  (b) Any Rights Certificate issued pursuant hereto that
represents Rights beneficially owned by: (i) an Acquiring Person or any
Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) which becomes a transferee after
the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person
(or of any such Associate or Affiliate) which becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and which receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
the Acquiring Person (or any such Associate or Affiliate) to holders of equity
interests in such Acquiring Person (or such Associate or Affiliate) or to any
Person with whom such Acquiring Person (or such Associate or Affiliate) has any
continuing agreement, arrangement or understanding regarding either the
transferred Rights, shares of Company Common Stock or the Company or (B) a
transfer which the Company's Board of Directors has determined to be part of a
plan, arrangement or understanding which has as a primary purpose or effect the
avoidance of Section 7(e) hereof shall, upon the written direction of the
Company's Board of Directors, contain (to the extent feasible) the following
legend:


<PAGE>   10


                                        8

                  The Rights represented by this Rights Certificate are or were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate or Associate of an Acquiring Person (as such terms are
         defined in the Amended and Restated Rights Agreement). Accordingly,
         this Rights Certificate and the Rights represented hereby may become
         null and void in the circumstances specified in Section 7(e) of such
         Agreement.

                  SECTION 5. Countersignature and Registration. (a) Rights
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its President or one of its Vice Presidents, under its corporate seal
reproduced thereon attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Rights Certificates
may be manual or facsimile. Rights Certificates bearing the manual or facsimile
signatures of the individuals who were at any time the proper officers of the
Company shall bind the Company, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the countersignature of such
Rights Certificates or did not hold such offices at the date of such Rights
Certificates. No Rights Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose unless there appears on such Rights
Certificate a countersignature duly executed by the Rights Agent by manual
signature of an authorized officer, and such countersignature upon any Rights
Certificate shall be conclusive evidence, and the only evidence, that such
Rights Certificate has been duly countersigned as required hereunder.

                  (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at its office designated for surrender of Rights
Certificates upon exercise or transfer, books for registration and transfer of
the Rights Certificates issued hereunder. Such books shall show the name and
address of each holder of the Rights Certificates, the number of Rights
evidenced on its face by each Rights Certificate and the date of each Rights
Certificate.

                  SECTION 6. Transfer, Split Up, Combination and Exchange of
Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.
(a) Subject to the provisions of Sections 4(b), 7(e) and 14 hereof, at any time
after the Close of Business on the Distribution Date, and at or prior to the
Close of Business on the Expiration Date, any Rights Certificate or Certificates
may be transferred, split up, combined or exchanged for another Rights
Certificate or Certificates, entitling the registered holder to purchase a like
number of Units of Preferred Stock (or, following a Triggering Event, other
securities, cash or other assets, as the case may be) as the Rights Certificate
or Certificates surrendered then entitled such holder to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any Rights
Certificate or Certificates shall make such request in writing delivered to the
Rights Agent, and shall surrender the Rights Certificate or Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose. Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered Rights Certificate until the registered holder shall have completed
and executed the certificate set forth in the form of assignment on the reverse
side of such Rights Certificate and shall have provided such additional evidence
of the identity of the Beneficial Owner (or former Beneficial Owner) of the
Rights represented by such Rights Certificate or Affiliates or Associates
thereof as the Company shall reasonably request; whereupon the Rights Agent
shall, subject to the provisions of Section 4(b), Section 7(e) and


<PAGE>   11


                                        9

Section 14 hereof, countersign and deliver to the Person entitled thereto a
Rights Certificate or Rights Certificates, as the case may be, as so requested.
The Company may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer, split
up, combination or exchange of Rights Certificates.

                  (b) If a Rights Certificate shall be mutilated, lost, stolen
or destroyed, upon request by the registered holder of the Rights represented
thereby and upon payment to the Company and the Rights Agent of all reasonable
expenses incident thereto, there shall be issued, in exchange for and upon
cancellation of the mutilated Rights Certificate, or in substitution for the
lost, stolen or destroyed Rights Certificate, a new Rights Certificate, in
substantially the form of the prior Rights Certificate, of like tenor and
representing the equivalent number of Rights, but, in the case of loss, theft or
destruction, only upon receipt of evidence satisfactory to the Company and the
Rights Agent of such loss, theft or destruction of such Rights Certificate and,
if requested by the Company or the Rights Agent, indemnity also satisfactory to
it.

                  SECTION 7. Exercise of Rights; Purchase Price; Expiration Date
of Rights. (a) Prior to the earlier of (i) the Close of Business on May 4, 2010
(the "Final Expiration Date"), and (ii) the time at which the Rights are
redeemed as provided in Section 23 hereof (the earlier of (i) and (ii) being the
"Expiration Date"), the registered holder of any Rights Certificate may, subject
to the provisions of Sections 7(e) and 9(c) hereof, exercise the Rights
evidenced thereby in whole or in part at any time after the Distribution Date
upon surrender of the Rights Certificate, with the form of election to purchase
and the certificate on the reverse side thereof duly executed, to the Rights
Agent at the office of the Rights Agent designated for such purpose, together
with payment of the aggregate Purchase Price (as hereinafter defined) for the
number of Units of Preferred Stock (or, following a Triggering Event, other
securities, cash or other assets, as the case may be) for which such surrendered
Rights are then exercisable.

                  (b) The purchase price for each one one-hundredth of a share
(each such one one-hundredth of a share being a "Unit") of Preferred Stock upon
exercise of Rights shall be $30.00, subject to adjustment from time to time as
provided in Sections 11 and 13(a) hereof (such purchase price, as so adjusted,
being the "Purchase Price"), and shall be payable in accordance with paragraph
(c) below.

                  (c) As promptly as practicable following the occurrence of the
Distribution Date, the Company shall deposit with a corporation in good standing
organized under the laws of the United States or any State of the United States,
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 (such institution being the "Depositary Agent"), certificates
representing the shares of Preferred Stock that may be acquired upon exercise of
the Rights and shall cause such Depositary Agent to enter into an agreement
pursuant to which the Depositary Agent shall issue receipts representing
interests in the shares of Preferred Stock so deposited. Upon receipt of a
Rights Certificate representing exercisable Rights, with the form of election to
purchase and the certificate duly executed, accompanied by payment, with respect
to each Right so exercised, of the Purchase Price for the Units of Preferred
Stock (or, following a Triggering Event, other securities, cash or other assets,
as the case may be) to be purchased thereby as set forth below and


<PAGE>   12


                                       10

an amount equal to any applicable transfer tax or evidence satisfactory to the
Company of payment of such tax, the Rights Agent shall, subject to Section 20(k)
hereof, thereupon promptly (i) requisition from the Depositary Agent depositary
receipts representing such number of Units of Preferred Stock as are to be
purchased and the Company will direct the Depositary Agent to comply with such
request, (ii) requisition from the Company the amount of cash, if any, to be
paid in lieu of fractional shares in accordance with Section 14 hereof, (iii)
after receipt of such depositary, receipts, cause the same to be delivered to or
upon the order of the registered holder of such Rights Certificate, registered
in such name or names as may be designated by such holder, and (iv) after
receipt thereof, deliver such cash, if any, to or upon the order of the
registered holder of such Rights Certificate. In the event that the Company is
obligated to issue Company Common Stock, other securities of the Company, pay
cash and/or distribute other property pursuant to Section 11(a) hereof, the
Company will make all arrangements necessary so that such Company Common Stock,
other securities, cash and/or other property are available for distribution by
the Rights Agent, if and when appropriate. Subject to Section 34, the payment of
the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)
hereof) may be made in cash or by certified or bank check or money order payable
to the order of the Company, or by wire transfer of immediately available funds
to the account of the Company (provided that notice of such wire transfer shall
be given by the holder of related Rights to the Rights Agent).

                  (d) In case the registered holder of any Rights Certificate
shall exercise less than all the Rights evidenced thereby, a new Rights
Certificate evidencing the Rights remaining unexercised shall be issued by the
Rights Agent and delivered to, or upon the order of, the registered holder of
such Rights Certificate, registered in such name or names as may be designated
by such holder, subject to the provisions of Section 14 hereof.

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Section 11(a)(ii) Event or
Section 13 Event, any Rights beneficially owned by (i) an Acquiring Person or an
Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) which becomes a transferee after
the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person
(or of any such Associate or Affiliate) which becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and which receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
the Acquiring Person (or any such Associate or Affiliate) to holders of equity
interests in such Acquiring Person (or any such Associate or Affiliate) or to
any Person with whom such Acquiring Person (or such Associate or Affiliate) has
any continuing agreement, arrangement or understanding regarding the transferred
Rights, shares of Company Common Stock or the Company or (B) a transfer which
the Company's Board of Directors has determined to be part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of this Section 7(e), shall be null and void without any further
action, and no holder of such Rights shall have any rights whatsoever with
respect to such Rights, whether under any provision of this Agreement or
otherwise. The Company shall use all reasonable efforts to ensure that the
provisions of this Section 7(e) and Section 4(b) hereof are complied with, but
shall have no liability to any holder of Rights or any other Person as a result
of its failure to make any determination under this Section 7(e) or such Section
4(b) with respect to an Acquiring Person or its Affiliates, Associates or
transferees.

<PAGE>   13
                                       11

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

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

                  SECTION 9. Reservation and Availability of Capital Stock. (a)
The Company shall at all times prior to the Expiration Date cause to be reserved
and kept available, out of its authorized and unissued shares of Preferred
Stock, the number of shares of Preferred Stock that, as provided in this
Agreement, will be sufficient to permit the exercise in full of all outstanding
Rights. Upon the occurrence of any events resulting in an increase in the
aggregate number of shares of Preferred Stock (or other equity securities of the
Company) issuable upon exercise of all outstanding Rights above the number then
reserved, the Company shall make appropriate increases in the number of shares
so reserved.

                  (b) If the shares of Preferred Stock to be issued and
delivered upon the exercise of the Rights may be listed on any national
securities exchange, the Company shall during the period from the Distribution
Date through the Expiration Date use its best efforts to cause all securities
reserved for such issuance to be listed on such exchange upon official notice of
issuance upon such exercise.

                  (c) The Company shall use its best efforts (i) as soon as
practicable following the occurrence of a Section 11(a)(ii) Event and a
determination by the Company in accordance with Section 11(a)(iii) hereof of the
consideration to be delivered by the Company upon exercise of the Rights or, if
so required by law, as soon as practicable following the Distribution Date (such
date being the "Registration Date"), to file a registration statement on an
appropriate form under the Securities Act of 1933, as amended (the "Securities
Act"), with respect to the securities that may be acquired upon exercise of the
Rights (the "Registration Statement"), (ii) to cause the Registration Statement
to become effective as soon as practicable after such filing, (iii) to cause the
Registration Statement to continue to be effective (and to include a prospectus
complying


<PAGE>   14


                                       12

with the requirements of the Securities Act) until the earlier of (A) the date
as of which the Rights are no longer exercisable for the securities covered by
the Registration Statement and (B) the Expiration Date and (iv) to take as soon
as practicable following the Registration Date such action as may be required to
ensure that any acquisition of securities upon exercise of the Rights complies
with any applicable state securities or "blue sky" laws. If the Registration
Statement does not become effective prior to the close of business on the 60th
Business Day following the occurrence of a Section 11(a)(ii) Event, the Company
shall, unless otherwise determined by the Board of Directors, on the 61st
Business Day following the occurrence of such Section 11(a)(ii) Event, be
obligated to exercise the option described in Section 34.

                  (d) The Company shall take such action as may be necessary to
ensure that all shares of Preferred Stock (and, following the occurrence of a
Triggering Event, any other securities that may be delivered upon exercise of
Rights) shall be, at the time of delivery of the certificates or depositary
receipts for such securities, duly and validly authorized and issued and fully
paid and non-assessable.

                  (e) The Company shall pay any documentary, stamp or transfer
tax imposed in connection with the issuance or delivery of the Rights
Certificates or upon the exercise of Rights; provided, however, the Company
shall not be required to pay any such tax imposed in connection with the
issuance or delivery of Units of Preferred Stock, or any certificates or
depositary receipts for such Units of Preferred Stock (or, following the
occurrence of a Triggering Event, any other securities, cash or assets, as the
case may be) to any person other than the registered holder of the Rights
Certificates evidencing the Rights surrendered for exercise. The Company shall
not be required to issue or deliver any certificates or depositary receipts for
Units of Preferred Stock (or, following the occurrence of a Triggering Event,
any other securities, cash or assets, as the case may be) to, or in a name other
than that of, the registered holder of the Rights Certificate upon the exercise
of any Rights represented thereby until any such tax shall have been paid (any
such tax being payable by the holder of such Rights Certificate at the time of
surrender) or until it has been established to the Company's satisfaction that
no such tax is due.

                  SECTION 10. Preferred Stock Record Date. Each Person in whose
name any certificate for Units of Preferred Stock (or, following the occurrence
of a Triggering Event, other securities) is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of the
Units of Preferred Stock (or, following the occurrence of a Triggering Event,
other securities) represented thereby on, and such certificate shall be dated,
the date upon which the Rights Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Stock (or, following the occurrence
of a Triggering Event, other securities) transfer books of the Company are
closed, such Person shall be deemed to have become the record holder of such
securities and such certificate shall be dated, the next succeeding Business Day
on which the Preferred Stock (or, following the occurrence of a Triggering
Event, other securities) transfer books of the Company are open and, further
provided, however, that if delivery of Units of Preferred Stock is delayed as a
result of a failure to register such Units of Preferred Stock pursuant to
Section 9(c) hereof, such Persons shall be deemed to have become the record
holders of such Units of Preferred Stock only


<PAGE>   15

when such Units first become deliverable. Prior to the exercise of the Rights
evidenced thereby, the holder of a Rights Certificate shall not be entitled to
any rights of a shareholder of the Company with respect to securities for which
the Rights shall be exercisable, including, without limitation, the right to
vote, to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of
the Company, except as provided herein.

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

                  (a) (i) In the event the Company shall at any time after the
         date of this Agreement (A) declare a dividend on the Preferred Stock
         payable in shares of Preferred Stock, (B) subdivide the outstanding
         Preferred Stock, (C) combine the outstanding Preferred Stock into a
         smaller number of shares, or (D) issue any shares of its capital stock
         in a reclassification of the Preferred Stock (including any such
         reclassification in connection with a consolidation or merger in which
         the Company is the continuing or surviving corporation), except as
         otherwise provided in this Section 11(a), the Purchase Price in effect
         at the time of the record date for such dividend or of the effective
         date of such subdivision, combination or reclassification, and the
         number and kind of shares of Preferred Stock or capital stock, as the
         case may be, issuable on such date upon exercise of the Rights, shall
         be proportionately adjusted so that the holder of any Right exercised
         after such time shall be entitled to receive, upon payment of the
         Purchase Price then in effect, the aggregate number and kind of shares
         of Preferred Stock or capital stock, as the case may be, which, if such
         Right had been exercised immediately prior to such date, such holder
         would have owned upon such exercise and been entitled to receive by
         virtue of such dividend, subdivision, combination or reclassification.
         If an event occurs which would require an adjustment under both this
         Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided
         for in this Section 11(a)(i) shall be in addition to, and shall be made
         prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

                  (ii)     In the event:

                           (A) any Acquiring Person or any Associate or
                  Affiliate of any Acquiring Person, at any time after the date
                  of this Agreement, directly or indirectly, (1) shall merge
                  into the Company or otherwise combine with the Company and the
                  Company shall be the continuing or surviving corporation of
                  such merger or combination and Company Common Stock shall
                  remain outstanding and unchanged, (2) shall, in one
                  transaction or a series of transactions, transfer any assets
                  to the Company or to any of its Subsidiaries in exchange (in
                  whole or in part) for shares of Company Common Stock, for
                  other equity securities of the Company or any such Subsidiary,
                  or for securities exercisable for or convertible into shares
                  of equity securities of the Company or any of its Subsidiaries
                  (whether Company Common Stock or otherwise) or otherwise
                  obtain

                  from the Company or any of its Subsidiaries, with or without
                  consideration, any additional shares of such equity securities
                  or securities exercisable for or convertible into such equity
                  securities (other than pursuant to a pro rata distribution to
                  all holders of Company Common Stock), (3) shall sell,
                  purchase, lease, exchange, mortgage, pledge, transfer or
                  otherwise acquire or dispose of, in one transaction or a
                  series of transactions, to, from or with (as the case may be)
                  the Company or any of its Subsidiaries or any employee benefit
                  plan maintained by the Company or any of its Subsidiaries or
                  any trustee or fiduciary with respect to such plan acting in
                  such capacity, assets (including securities) on terms and
                  conditions less favorable to the Company or such Subsidiary or
                  plan than those that could have been obtained in arm's-length
                  negotiations with an unaffiliated third party, other than
                  pursuant to a transaction set forth in Section 13(a) hereof,
                  (4) shall sell, purchase, lease, exchange, mortgage, pledge,
                  transfer or otherwise acquire or dispose of, in one
                  transaction or a series of transactions, to, from or with the
                  Company or any of the Company's Subsidiaries or any employee
                  benefit plan maintained by the Company or any of its
                  Subsidiaries or any trustee or fiduciary with respect to such
                  plan acting in such capacity (other than transactions, if any,
                  consistent with those engaged in, as of the date hereof, by
                  the Company and such Acquiring Person or such Associate or
                  Affiliate), assets (including securities) having an aggregate
                  fair market value of more than $1,000,000, other than pursuant
                  to a transaction set forth in Section 13(a) hereof, (5) shall
                  sell, purchase, lease, exchange, mortgage, pledge, transfer or
                  otherwise acquire or dispose of, in one transaction or a
                  series of transactions, to, from or with the Company or any of
                  its Subsidiaries or any employee benefit plan maintained by
                  the Company or any of its Subsidiaries or any trustee or
                  fiduciary with respect to such plan acting in such capacity,
                  any material trademark or material service mark, other than
                  pursuant to a transaction set forth in Section 13(a) hereof,
                  (6) shall receive, or any designee, agent or representative of
                  such Acquiring Person or any Affiliate or Associate of such
                  Acquiring Person shall receive, any compensation from the
                  Company or any of its Subsidiaries other than compensation for
                  full-time employment as a regular employee at rates in
                  accordance with the Company's (or its Subsidiaries') past
                  practices, or (7) shall receive the benefit, directly or
                  indirectly (except proportionately as a holder of Company
                  Common Stock or as required by law or governmental
                  regulation), 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 any employee benefit plan maintained by the Company or any
                  of its Subsidiaries or any trustee or fiduciary with respect
                  to such plan acting in such capacity; or

                           (B) any Person shall become an Acquiring Person,
                  unless the event causing such Person to become an Acquiring
                  Person is a transaction set forth in Section 13(a) hereof; or

                           (C) during such time as there is an Acquiring Person,
                  there shall be any reclassification of securities (including
                  any reverse stock split), or 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,
                  other than a transaction or transactions to which the
                  provisions of Section 13(a) apply (whether or not with or into
                  or otherwise involving an Acquiring Person), 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
                  which is directly or indirectly beneficially owned by any
                  Acquiring Person or any Associate or Affiliate of any
                  Acquiring Person;

         then, immediately upon the date of the occurrence of an event described
         in Section 11(a)(ii)(A), (B) or (C) hereof (a "Section 11(a)(ii)
         Event"), proper provision shall be made so that each holder of a Right
         (except as provided below and in Section 7(e) hereof) shall thereafter
         have the right to receive, upon exercise thereof at the then current
         Purchase Price in accordance with the terms of this Agreement, in lieu
         of the number of Units of Preferred Stock for which a Right was
         exercisable immediately prior to the first occurrence of a Section
         11(a)(ii) Event, such number of shares of Company Common Stock as shall
         equal the result obtained by (x) multiplying the then current Purchase
         Price by the then number of Units of Preferred Stock for which a Right
         was exercisable immediately prior to the first occurrence of a Section
         11(a)(ii) Event (such product thereafter being, for all purposes of
         this Agreement other than Section 13 hereof, the "Purchase Price"), and
         (y) dividing the product by 50% of the then current market price
         (determined pursuant to Section 11(d) hereof) per share of Company
         Common Stock on the date of such first occurrence (such shares of
         Company Common Stock being the "Adjustment Shares").

                  (iii) In the event that the number of shares of Company Common
         Stock which are authorized by the Company's Restated Articles of
         Incorporation, and neither outstanding nor reserved for issuance for
         purposes other than upon exercise of the Rights, is not sufficient to
         permit the exercise in full of the Rights in accordance with the
         foregoing subparagraph (ii) of this Section 11(a), the Company, by the
         vote of the Company's Board of Directors, shall: (A) determine the
         excess of (1) the value of the Adjustment Shares issuable upon the
         exercise of a Right (the "Current Value") over (2) the Purchase Price
         (such excess being the "Spread"), and (B) with respect to each Right,
         make adequate provision to substitute for such Adjustment Shares, upon
         payment of the applicable Purchase Price, (1) such number of Units of
         Preferred Stock which is the product of such Adjustment Shares
         multiplied by

                                    (1 - A )
                                        ---
                                         B
         where:



<PAGE>   18


                                        16

                  A = the number of shares of Company Common Stock
                      authorized and neither outstanding nor reserved for
                      issuance for purposes other than upon exercise of the
                      Rights; and

                  B = the number of shares of Company Common Stock
                      sufficient to permit the exercise in full of the
                      Rights in accordance with the foregoing subparagraph
                      (ii) of this Section 11(a),

         (2) cash, (3) a reduction in the Purchase Price, (4) other equity
         securities of the Company (including, without limitation, shares, or
         units of shares, of preferred stock (such other shares being "preferred
         stock equivalents")), (5) debt securities of the Company, (6) other
         assets, or (7) any combination of the foregoing having an aggregate
         value equal to the Current Value, where such aggregate value has been
         determined by the Company's Board of Directors, after receiving advice
         from a nationally recognized investment banking firm; provided,
         however, that the Company may substitute the consideration specified in
         clauses (2) - (7) above only in the event that the number of shares of
         Preferred Stock authorized by the Company's Articles of Incorporation
         is inadequate for the purposes hereof; and provided further, however,
         that if the Company shall not have made adequate provision to deliver
         value pursuant to clause (B) above within thirty days following the
         later of (x) the first occurrence of a Section 11(a)(ii) Event and (y)
         the date on which the Company's right of redemption pursuant to Section
         23(a) expires (the later of (x) and (y) being referred to herein as the
         "Section 11(a)(iii) Trigger Date"), then the Company shall be obligated
         to deliver, upon the surrender for exercise of a Right and without
         requiring payment of the Purchase Price, shares of Company Common Stock
         (to the extent available), Units of Preferred Stock (to the extent
         available) and then, if necessary, cash, which shares of Company Common
         Stock, Units of Preferred Stock and/or cash shall have an aggregate
         value equal to the Spread. To the extent that the Company determines
         that some action need be taken pursuant to the first sentence of this
         Section 11(a)(iii), the Company shall provide, subject to Section 7(e)
         hereof, that such action shall apply uniformly to all outstanding
         Rights. For purposes of this Section 11(a)(iii), the value of a share
         of Company Common Stock or a Unit of Preferred Stock shall be the
         current market price (as determined pursuant to Section 11(d) hereof)
         per share of Company Stock or of Preferred Stock, as the case may be,
         on the Section 11(a)(iii) Trigger Date and the value of any preferred
         stock equivalent shall be deemed to have the same value as the
         Preferred Stock on such date.

                  (b) In case the Company shall fix a record date for the
         issuance of rights, options or warrants to all holders of Preferred
         Stock entitling them to subscribe for or purchase (for a period
         expiring within forty-five calendar days after such record date) shares
         of Preferred Stock (or shares having substantially the same rights,
         privileges and preferences as shares of Preferred Stock ("equivalent
         preferred stock")) or securities convertible into Preferred Stock or
         equivalent preferred stock at a price per share of Preferred Stock or
         per share of equivalent preferred stock (or having a conversion price
         per share, if a security convertible into Preferred Stock or equivalent
         preferred stock) less than the current market price (as determined
         pursuant to Section 11(d) hereof) per share


<PAGE>   19


                                       17

         of Preferred Stock on such record date, the Purchase Price to be in
         effect after such record date shall be determined by multiplying the
         Purchase Price in effect immediately prior to such record date by a
         fraction, the numerator of which shall be the sum of the number of
         shares of Preferred Stock outstanding on such record date plus the
         number of shares of Preferred Stock which the aggregate offering price
         of the total number of shares of Preferred Stock and/or equivalent
         preferred stock so to be offered (and/or the aggregate initial
         conversion price of the convertible securities so to be offered) would
         purchase at such current market price, and the denominator of which
         shall be the number of shares of Preferred Stock outstanding on such
         record date plus the number of additional shares of Preferred Stock
         and/or equivalent preferred stock to be offered for subscription or
         purchase (or into which the convertible securities so to be offered are
         initially convertible). In case such subscription price may be paid by
         delivery of consideration part or all of which may be in a form other
         than cash, the value of such consideration shall be as determined in
         good faith by the Company's Board of Directors, whose determination
         shall be described in a statement filed with the Rights Agent and shall
         be binding on the Rights Agent and the holders of the Rights. Shares of
         Preferred Stock owned by or held for the account of the Company or any
         Subsidiary shall not be deemed outstanding for the purpose of any such
         computation. Such adjustment shall be made successively whenever such a
         record date is fixed, and in the event that such rights or warrants are
         not so issued, the Purchase Price shall be adjusted to be the Purchase
         Price which would then be in effect if such record date had not been
         fixed.

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

                  (d) (i) For the purpose of any computation hereunder, the
         "current market price" per share of Company Common Stock or Common
         Stock on any date shall be deemed to be the average of the daily
         closing prices per share of such shares for the ten consecutive Trading
         Days (as such term is hereinafter defined) immediately prior to such
         date; provided, however, if prior to the expiration of such requisite
         ten Trading Day period the issuer announces either (A) a dividend or
         distribution on such shares payable in such shares or securities
         convertible into such shares (other than the Rights), or (B) any
         subdivision, combination or reclassification of such shares, then,
         following the ex- dividend date for such dividend or the record date
         for such subdivision, as the case may be, the "current market price"
         shall be properly adjusted to take into account such event. The closing
         price for each day shall be, if the shares are listed and admitted to
         trading on a national securities exchange, as reported in the principal
         consolidated transaction reporting system with respect to securities
         listed on the principal national securities exchange on which such
         shares are listed or admitted to trading or, if such 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 The
         Nasdaq Stock Market Consolidated Quotations Service ("NASDAQ") or such
         other system then in use, or, if on any such date such 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 such shares selected by the Company's Board of Directors. If
         on any such date no market maker is making a market in such shares, the
         fair value of such shares on such date as determined in good faith by
         the Company's Board of Directors shall be used. If such shares are not
         publicly held or not so listed or traded, "current market price" per
         share shall mean the fair value per share as determined in good faith
         by the Company's Board of Directors, whose determination shall be
         described in a statement filed with the Rights Agent and shall be
         conclusive for all purposes. The term "Trading Day" shall mean, if such
         shares are listed or admitted to trading on any national securities
         exchange, a day on which the principal national securities exchange on
         which such shares are listed or admitted to trading is open for the
         transaction of business or, if such shares are not so listed or
         admitted, a Business Day.

                  (ii) For the purpose of any computation hereunder, the
         "current market price" per share of Preferred Stock shall be determined
         in the same manner as set forth above for Company Common Stock in
         clause (i) of this Section 11(d) (other than the fourth sentence
         thereof). If the current market price per share of Preferred Stock
         cannot be determined in the manner provided above or if the Preferred
         Stock is not publicly held or listed or traded in a manner described in
         clause (i) of this Section 11(d), the "current market price" per share
         of Preferred Stock shall be conclusively deemed to be an amount equal
         to 100 (as such amount may be appropriately adjusted for such events as
         stock splits, stock dividends and recapitalizations with respect to
         Company Common Stock occurring after the date of this Agreement)
         multiplied by the current market price per share of Company Common
         Stock. If neither Company Common Stock nor Preferred Stock is publicly
         held or so listed or traded, "current market price" per share of the
         Preferred Stock shall mean the fair value per share as determined in
         good faith by the Company's Board of Directors whose determination
         shall be described in a statement


<PAGE>   21


                                       19

         filed with the Rights Agent and shall be binding on the Rights Agent
         and holders of the Rights. For all purposes of this Agreement, the
         "current market price" of a Unit of Preferred Stock shall be equal to
         the "current market price" of one share of Preferred Stock divided by
         100.

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

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

                  (g) All Rights originally issued by the Company subsequent to
         any adjustment made to the Purchase Price hereunder shall evidence the
         right to purchase, at the adjusted Purchase Price, the number of Units
         of Preferred Stock (or other securities or amount of cash or
         combination thereof) that may be acquired from time to time hereunder
         upon exercise of the Rights, all subject to further adjustment as
         provided herein.

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






<PAGE>   22

                                       20

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

                  (j) Irrespective of any adjustment or change in the Purchase
         Price or the number of Units of Preferred Stock issuable upon the
         exercise of the Rights, the Rights Certificates theretofore and
         thereafter issued may continue to express the Purchase Price per Unit
         and the number of Units of Preferred Stock which was expressed in the
         Initial Rights Certificates issued hereunder without prejudice to any
         such adjustment or change.

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

                  (l) In any case in which this Section 11 shall require that an
         adjustment in the Purchase Price be made effective as of a record date
         for a specified event, the Company may elect to defer until the
         occurrence of such event the issuance to the holder of any Right
         exercised after such record date of that number of Units of Preferred
         Stock and


<PAGE>   23


                                       21

         shares of other capital stock or securities of the Company, if any,
         issuable upon such exercise over and above the number of Units of
         Preferred Stock and shares of other capital stock or securities of the
         Company, if any, issuable upon such exercise on the basis of the
         Purchase Price in effect prior to such adjustment; provided, however,
         that the Company shall deliver to such holder a due bill or other
         appropriate instrument evidencing such holder's right to receive such
         additional shares (fractional or otherwise) or securities upon the
         occurrence of the event requiring such adjustment.

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

                  (n) The Company shall not, at any time after the Distribution
         Date, (i) consolidate with any other Person (other than a Subsidiary of
         the Company in a transaction which complies with Section 11(o) hereof),
         (ii) merge with or into any other Person (other than a Subsidiary of
         the Company in a transaction which complies with Section 11(o) hereof),
         or (iii) sell or transfer (or permit any Subsidiary to sell or
         transfer), in one transaction, or a series of transactions, assets or
         earning power aggregating more than 50% of the assets or earning power
         of the Company and its Subsidiaries (taken as a whole) to any other
         Person or Persons (other than the Company and/or any of its
         Subsidiaries in one or more transactions each of which complies with
         Section 11(o) hereof), if (x) at the time of or immediately after such
         consolidation, merger or sale there are any rights, warrants or other
         instruments or securities outstanding or agreements in effect which
         would substantially diminish or otherwise eliminate the benefits
         intended to be afforded by the Rights or (y) prior to, simultaneously
         with or immediately after such consolidation, merger or sale, the
         Person which constitutes, or would constitute, the "Principal Party"
         for purposes of Section 13(a) hereof shall have distributed or
         otherwise transferred to its shareholders or other persons holding an
         equity interest in such Person Rights previously owned by such Person
         or any of its Affiliates and Associates; provided, however, this
         Section 11(n) shall not affect the ability of any Subsidiary of the
         Company to consolidate with, merge with or into, or sell or transfer
         assets or earning power to, any other Subsidiary of the Company.

                  (o) After the Distribution Date, the Company shall not, except
         as permitted by Section 23 or Section 26 hereof, 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 diminish substantially
         or otherwise eliminate the benefits intended to be afforded by the
         Rights.

                                       22


                  (p) Anything in this Agreement to the contrary
         notwithstanding, in the event that the Company shall at any time after
         the Rights Dividend Declaration Date and prior to the Distribution Date
         (i) declare a dividend on the outstanding shares of Company Common
         Stock payable in shares of Company Common Stock, (ii) subdivide the
         outstanding shares of Company Common Stock, (iii) combine the
         outstanding shares of Company Common Stock into a smaller number of
         shares, or (iv) issue any shares of its capital stock in a
         reclassification of Company Common Stock (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 share of Company Common Stock then
         outstanding, or issued or delivered thereafter but prior to the
         Distribution Date, shall be proportionately adjusted so that the number
         of Rights thereafter associated with each share of Company Common Stock
         following any such event shall equal the result obtained by multiplying
         the number of Rights associated with each share of Company Common Stock
         immediately prior to such event by a fraction the numerator of which
         shall be the total number of shares of Company Common Stock outstanding
         immediately prior to the occurrence of the event and the denominator of
         which shall be the total number of shares of Company Common Stock
         outstanding immediately following the occurrence of such event.

                  SECTION 12. Certificate of Adjusted Purchase Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11 or Section
13 hereof, the Company shall (a) promptly prepare a certificate setting forth
such adjustment and a brief statement of the facts accounting for such
adjustment, (b) promptly file with the Rights Agent, and with each transfer
agent for the Preferred Stock and the Company Common Stock, a copy of such
certificate, and (c) mail a brief summary thereof to each holder of a Rights
Certificate (or, if prior to the Distribution Date, to each holder of a
certificate representing shares of Company Common Stock) in accordance with
Section 25 hereof. The Rights Agent shall be fully protected in relying on any
such certificate and on any adjustment therein contained and shall not be deemed
to have knowledge of any such adjustment unless and until it shall have received
such certificate.

                  SECTION 13. Consolidation, Merger or Sale or Transfer of
Assets or Earning Power. (a) In the event that, following the Stock Acquisition
Date, directly or indirectly, either (x) the Company shall consolidate with, or
merge with or into, any other Person (other than a Subsidiary of the Company in
a transaction which complies with Section 11(o) hereof), and the Company shall
not be the continuing or surviving corporation of such consolidation or merger,
(y) any Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof) shall consolidate with, or merge with or
into, the Company, and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such
consolidation or merger, all or part of the outstanding shares of Company Common
Stock shall be converted into or exchanged for stock or other securities of any
other Person or cash or any other property, or (z) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer) to any Person or Persons (other than the Company or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), in one or more transactions, assets or earning power aggregating


<PAGE>   25


                                       23

more than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) (any such event described in clause (x), (y) or (z) being a
"Section 13 Event"), then, and in each such case, proper provision shall be made
so that: (i) each holder of a Right, except as provided in Section 7(e) hereof,
shall thereafter have the right to receive, upon the exercise thereof at the
then current Purchase Price, such number of validly authorized and issued, fully
paid and non-assessable shares of Common Stock of the Principal Party (as such
term is hereinafter defined), which shares shall not be subject to any liens,
encumbrances, rights of first refusal, transfer restrictions or other adverse
claims, as shall be equal to the result obtained by (1) multiplying the then
current Purchase Price by the number of Units of Preferred Stock for which a
Right is exercisable immediately prior to the first occurrence of a Section 13
Event (or, if a Section 11(a)(ii) Event has occurred prior to the first
occurrence of a Section 13 Event, multiplying the number of such Units for which
a Right would be exercisable hereunder but for the occurrence of such Section
11(a)(ii) Event by the Purchase Price which would be in effect hereunder but for
such first occurrence) and (2) dividing that product (which, following the first
occurrence of a Section 13 Event, shall be the "Purchase Price" for all purposes
of this Agreement) by 50% of the current market price (determined pursuant to
Section 11(d) hereof) per share of the Common Stock of such Principal Party on
the date of consummation of such Section 13 Event; (ii) such Principal Party
shall thereafter be liable for, and shall assume, by virtue of such Section 13
Event, all the obligations and duties of the Company pursuant to this Agreement;
(iii) the term "Company" shall, for all purposes of this Agreement, thereafter
be deemed to refer to such Principal Party, it being specifically intended that
the provisions of Section 11 hereof shall apply only to such Principal Party
following the first occurrence of a Section 13 Event; (iv) such Principal Party
shall take such steps (including, but not limited to, the reservation of a
sufficient number of shares of its Common Stock) in connection with the
consummation of any such transaction as may be necessary to ensure that the
provisions of this Agreement shall thereafter be applicable to its shares of
Common Stock thereafter deliverable upon the exercise of the Rights; and (v) the
provisions of Section 11(a)(ii) hereof shall be of no further effect following
the first occurrence of any Section 13 Event.

                  (b) "Principal Party" shall mean:

                  (i) in the case of any transaction described in clause (x) or
         (y) of the first sentence of Section 13(a), (A) the Person that is the
         issuer of any securities into which shares of Company Common Stock are
         converted in such merger or consolidation, or, if there is more than
         one such issuer, the issuer of Common Stock that has the highest
         aggregate current market price (determined pursuant to Section 11(d)
         hereof) and (B) if no securities are so issued, the Person that is the
         other party to such merger or consolidation, or, if there is more than
         one such Person, the Person the Common Stock of which has the highest
         aggregate current market price (determined pursuant to Section 11(d)
         hereof); and

                  (ii) in the case of any transaction described in clause (z) of
         the first sentence of Section 13(a), the Person that is the party
         receiving the largest portion of the assets or earning power
         transferred pursuant to such transaction or transactions, or, if each
         Person that is a party to such transaction or transactions receives the
         same portion of the assets or


<PAGE>   26


                                       24

         earning power transferred pursuant to such transaction or transactions
         or if the Person receiving the largest portion of the assets or earning
         power cannot be determined, whichever Person the Common Stock of which
         has the highest aggregate current market price (determined pursuant to
         Section 11(d) hereof);

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding
twelve-month period registered under Section 12 of the Exchange Act ("Registered
Common Stock"), or such Person is not a corporation, and such Person is a direct
or indirect Subsidiary of another Person that has Registered Common Stock
outstanding, "Principal Party" shall refer to such other Person; (2) if the
Common Stock of such Person is not Registered Common Stock or such Person is not
a corporation, and such Person is a direct or indirect Subsidiary of another
Person but is not a direct or indirect Subsidiary of another Person which has
Registered Common Stock outstanding, "Principal Party" shall refer to the
ultimate parent entity of such first-mentioned Person; (3) if the Common Stock
of such Person is not Registered Common Stock or such Person is not a
corporation, and such Person is directly or indirectly controlled by more than
one Person, and one or more of such other Persons has Registered Common Stock
outstanding, "Principal Party" shall refer to whichever of such other Persons is
the issuer of the Registered Common Stock having the highest aggregate current
market price (determined pursuant to Section 11(d) hereof); and (4) if the
Common Stock of such Person is not Registered Common Stock or such Person is not
a corporation, and such Person is directly or indirectly controlled by more than
one Person, and none of such other Persons have Registered Common Stock
outstanding, "Principal Party" shall refer to whichever ultimate parent entity
is the corporation having the greatest shareholders equity or, if no such
ultimate parent entity is a corporation, shall refer to whichever ultimate
parent entity is the entity having the greatest net assets.

                  (c) The Company shall not consummate any such consolidation,
merger, sale or transfer unless the Principal Party shall have a sufficient
number of authorized shares of its Common Stock which have not been issued or
reserved for issuance to permit the exercise in full of the Rights in accordance
with this Section 13, and unless prior thereto the Company and such Principal
Party shall have executed and delivered to the Rights Agent a supplemental
agreement providing for the terms set forth in paragraphs (a) and (b) of this
Section 13 and further providing that the Principal Party will:

                  (i) (A) file on an appropriate form, as soon as practicable
         following the execution of such agreement, a registration statement
         under the Securities Act with respect to the Common Stock that may be
         acquired upon exercise of the Rights, (B) cause such registration
         statement to remain effective (and to include a prospectus complying
         with the requirements of the Securities Act) until the Expiration Date,
         and (C) as soon as practicable following the execution of such
         agreement, take such action as may be required to ensure that any
         acquisition of such Common Stock upon the exercise of the Rights
         complies with any applicable state securities or "blue sky" laws; and



<PAGE>   27


                                       25

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

                  (d) In case the Principal Party which is to be a party to a
transaction referred to in this Section 13 has a provision in any of its
authorized securities or in its Certificate of Incorporation or By-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue, in connection with, or as a
consequence of, the consummation of a transaction referred to in this Section
13, shares of Common Stock of such Principal Party at less than the then current
market price per share (determined pursuant to Section 11(d) hereof) or
securities exercisable for, or convertible into, Common Stock of such Principal
Party at less than such then current market price (other than to holders of
Rights pursuant to this Section 13) or (ii) providing for any special payment,
tax or similar provisions in connection with the issuance of the Common Stock of
such Principal Party pursuant to the provisions of this Section 13; then, in
such event, the Company shall not consummate any such transaction unless prior
thereto the Company and such Principal Party shall have executed and delivered
to the Rights Agent a supplemental agreement providing that the provision in
question of such Principal Party shall have been cancelled, waived or amended,
or that the authorized securities shall be redeemed, so that the applicable
provision will have no effect in connection with, or as a consequence of, the
consummation of the proposed transaction.

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

                  SECTION 14. Fractional Rights and Fractional Shares. (a) The
Company shall not be required to issue fractions of Rights or to distribute
Rights Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the Persons to which such fractional Rights would
otherwise be issuable, an amount in cash equal to such fraction of the market
value of a whole Right. For purposes of this Section 14(a), the market value of
a whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable. The closing price of the Rights for any day shall be, if the
Rights are listed or admitted to trading on a national securities exchange, as
reported in the principal consolidated transaction reporting system with respect
to securities listed on the principal national securities exchange on which the
Rights are listed or admitted to trading or, if the Rights are not listed or
admitted to trading on any national securities exchange, the last quoted price
or, if not so quoted, the average of the high bid and low asked prices in the
over-the-counter market, as reported by NASDAQ or such other system then in use
or, if on any such date the Rights are not quoted by any such organization, the
average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Rights selected by the Company's Board of
Directors. If on any such date no such market maker is making a market in the
Rights, the fair value of the Rights on such date as determined in


<PAGE>   28


                                       26

good faith by the Company's Board of Directors shall be used and such
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

                  (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral multiples of
one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates which evidence such fractional shares of Preferred
Stock (other than fractions which are integral multiples of one one-hundredth of
a share of Preferred Stock). In lieu of such fractional shares of Preferred
Stock that are not integral multiples of one one-hundredth of a share, the
Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the then current market price of a share of Preferred Stock on the
day of exercise, determined in accordance Section 11(d) hereof.

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

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

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

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

                  (b) after the Distribution Date, the Rights Certificates are
         transferable only on the registry books of the Rights Agent if
         surrendered at the office of the Rights Agent


<PAGE>   29


                                       27

         designated for such purposes, duly endorsed or accompanied by a proper
         instrument of transfer and with the appropriate forms and certificates
         duly executed;

                  (c) subject to Section 6(a) and Section 7(f) hereof, the
         Company and the Rights Agent may deem and treat the person in whose
         name a Rights Certificate (or, prior to the Distribution Date, the
         associated Company Common Stock certificate) is registered as the
         absolute owner thereof and of the Rights evidenced thereby
         (notwithstanding any notations of ownership or writing on the Rights
         Certificates or the associated Company Common Stock certificate made by
         anyone other than the Company or the Rights Agent) for all purposes
         whatsoever, and neither the Company nor the Rights Agent, subject to
         the last sentence of Section 7(e) hereof, shall be affected by any
         notice to the contrary; and

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

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

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


<PAGE>   30


                                       28

                  (b) The Rights Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate or certificate for Preferred Stock or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement or other
paper or document believed by it to be genuine and to have been signed, executed
and, where necessary, verified or acknowledged by the proper Person or Persons.

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

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

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

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





<PAGE>   31
                                       29

          (b) Whenever in the performance of its duties under this Agreement the
     Rights Agent shall deem it necessary or desirable that any fact or matter
     (including, without limitation, the identity of any Acquiring Person and
     the determination of "current market price") be proved or established by
     the Company prior to taking or suffering any action hereunder, such fact or
     matter (unless other evidence in respect thereof be specified herein) may
     be deemed to be conclusively proved and established by a certificate signed
     by the Chairman of the Board, the President, any Vice President, the
     Treasurer, any Assistant Treasurer, the Secretary or any Assistant
     Secretary of the Company and delivered to the Rights Agent; and such
     certificate shall be full authorization to the Rights Agent for any action
     taken or suffered in good faith by it under the provisions of this
     Agreement in reliance upon such certificate.

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

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

          (e) The Rights Agent shall not have any responsibility for the
     validity of this Agreement or the execution and delivery hereof (except the
     due execution and delivery hereof by the Rights Agent) or for the validity
     or execution of any Rights Certificate (except its countersignature
     thereof); nor shall it be responsible for any breach by the Company of any
     covenant or failure by the Company to satisfy conditions contained in this
     Agreement or in any Rights Certificate; nor shall it be responsible for any
     adjustment required under the provisions of Section 11 or Section 13 hereof
     or for the manner, method or amount of any such adjustment or the
     ascertaining of the existence of facts that would require any such
     adjustment (except with respect to the exercise of Rights evidenced by
     Rights Certificates after receipt by the Rights Agent of the certificate
     describing any such adjustment contemplated by Section 12); nor shall it by
     any act hereunder be deemed to make any representation or warranty as to
     the authorization or reservation of any shares of Preferred Stock or any
     other securities to be issued pursuant to this Agreement or any Rights
     Certificate or as to whether any shares of Preferred Stock or any other
     securities will, when so issued, be validly authorized and issued, fully
     paid and non-assessable.

          (f) The Company shall perform, execute, acknowledge and deliver or
     cause to be performed, executed, acknowledged and delivered all such
     further acts, instruments and assurances as may reasonably be required by
     the Rights Agent for the performance by the Rights Agent of its duties
     under this Agreement.

          (g) The Rights Agent is hereby authorized and directed to accept
     instructions with respect to the performance of its duties hereunder from
     the Chairman of the Board,


<PAGE>   32


                                       30

     the President, any Vice President, the Secretary, any Assistant Secretary,
     the Treasurer or any Assistant Treasurer of the Company, and to apply to
     such officers for advice or instructions in connection with its duties, and
     it shall not be liable for any action taken or suffered to be taken by it
     in good faith in accordance with instructions of any such officer. Any
     application by the Rights Agent for written instructions from the Company
     may, at the option of the Rights Agent, set forth in writing any action
     proposed to be taken or omitted by the Rights Agent under this Rights
     Agreement and the date on and/or after which such action shall be taken or
     such omission shall be effective. The Rights Agent shall not be liable for
     any action taken by, or omission of, the Rights Agent in accordance with a
     proposal included in any such application on or after the date specified in
     such application (which date shall not be less than five Business Days
     after the date any such officer of the Company actually receives such
     application, unless any such officer shall have consented in writing to an
     earlier date) unless, prior to taking any such action (or the effective
     date in the case of an omission), the Rights Agent shall have received
     written instructions in response to such application specifying the action
     to be taken or omitted.

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

          (j) No provision of this Agreement shall require the Rights Agent to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties or in the exercise of its rights
     hereunder if the Rights Agent shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnification against such risk
     or liability is not reasonably assured to it.

          (k) If, with respect to any Rights Certificate surrendered to the
     Rights Agent for exercise or transfer, the certificate attached to the form
     of assignment or form of election to purchase, as the case may be, has
     either not been completed, not signed or indicates an affirmative response
     to clause 1 and/or 2 thereof, the Rights Agent shall not take any further
     action with respect to such requested exercise or transfer without first
     consulting with the Company. If such certificate has been completed and
     signed and shows a negative response to clauses 1 and 2 of such
     certificate, unless previously instructed otherwise in writing by the
     Company (which instructions may impose on the Rights Agent additional
     ministerial responsibilities, but no discretionary responsibilities), the
     Rights Agent may assume without further inquiry that the Rights Certificate
     is not


<PAGE>   33


                                       31

          owned by a person described in Section 4(b) or Section 7(e) hereof and
          shall not be charged with any knowledge to the contrary.

          SECTION 21. Change of Rights Agent. The Rights Agent or any successor
     Rights Agent may resign and be discharged from its duties under this
     Agreement upon thirty days' prior notice in writing mailed to the Company,
     and to each transfer agent of the Preferred Stock and the Company Common
     Stock, by registered or certified mail, and to the holders of the Rights
     Certificates (or certificates for the Company Common Stock prior to the
     Distribution Date) by first-class mail. The Company may remove the Rights
     Agent or any successor Rights Agent upon thirty days' prior 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 Stock and the Company
     Common Stock, by registered or certified mail, and to the holders of the
     Rights Certificates (or certificates for the Company Common Stock prior to
     the Distribution Date) by first-class mail. If the Rights Agent shall
     resign or be removed or shall otherwise become incapable of acting, the
     Company shall appoint a successor to the Rights Agent. If the Company shall
     fail to make such appointment within a period of thirty 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 Rights Certificate or, prior to the Distribution Date,
     the holder of a certificate for the Company Common Stock (who shall, with
     such notice, submit such holder's Rights Certificate or certificate for the
     Company Common Stock, as the case may be, for inspection by the Company),
     then any registered holder of any Rights Certificate or, prior to the
     Distribution Date, the holder of a certificate for the Company Common Stock
     may apply to any court of competent jurisdiction for the appointment of a
     new Rights Agent. Any successor Rights Agent, whether appointed by the
     Company or by such a court, shall be (a) a corporation organized and doing
     business under the laws of the United States or any state of the United
     States in good standing, shall be authorized to do business as a banking
     institution in the State of New York, shall be authorized under such laws
     to exercise corporate trust or stock transfer powers, shall be subject to
     supervision or examination by federal or state authorities and shall have
     at the time of its appointment as Rights Agent a combined capital and
     surplus of at least $100,000,000 or (b) an Affiliate of a corporation
     described in clause (a). After appointment, the successor Rights Agent
     shall be vested with the same powers, rights, duties and responsibilities
     as if it had been originally named as Rights Agent without further act or
     deed; but the predecessor Rights Agent shall deliver and transfer to the
     successor Rights Agent any property at the time held by it hereunder, and
     execute and deliver any further assurance, conveyance, act or deed
     necessary for the purpose. Not later than the effective date of any such
     appointment, the Company shall file notice thereof in writing with the
     predecessor Rights Agent and each transfer agent of the Preferred Stock and
     the Company Common Stock, and mail a notice thereof in writing to the
     registered holders of the Rights Certificates (or certificates for the
     Company Common Stock prior to the Distribution Date). Failure to give any
     notice provided for in this Section 21, however, or any defect therein,
     shall not affect the legality or validity of the resignation or removal of
     the Rights Agent or the appointment of the successor Rights Agent.

          SECTION 22. Issuance of New Rights Certificates. Notwithstanding any
     of the provisions of this Agreement or the Rights to the contrary, the
     Company may, at its option, issue new Rights Certificates evidencing Rights
     in such form as may be approved by the Company's


<PAGE>   34


                                       32

Board of Directors to reflect any adjustment or change made in accordance with
the provisions of this Agreement in the Purchase Price or the number or kind or
class of shares or other securities or property that may be acquired upon
exercise of the Rights. In addition, in connection with the issuance or sale of
shares of Company Common Stock following the Distribution Date and prior to the
Expiration Date, the Company (a) shall, with respect to shares of Company Common
Stock so issued or sold pursuant to the exercise of stock options or under any
employee plan or arrangement, or upon the exercise, conversion or exchange of
securities hereinafter issued by the Company, and (b) may, in any other case, if
deemed necessary or appropriate by the Company's Board of Directors, issue
Rights Certificates representing the appropriate number of Rights in connection
with such issuance or sale; provided, however, that (i) no such Rights
Certificate shall be issued if, and to the extent that, the Company shall be
advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the person to whom such
Rights Certificate would be issued, and (ii) no such Rights Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

     SECTION 23. Redemption and Termination. (a) Subject to Section 28 hereof,
the Company may, at its option, by action of the Company's Board of Directors,
at any time prior to the earlier of (i) the Close of Business on the tenth
Business Day following the Stock Acquisition Date, or (ii) the Final Expiration
Date, redeem all but not less than all of the then outstanding Rights at a
redemption price of $.01 per Right, as such amount may be appropriately adjusted
to reflect any stock split, stock dividend or similar transaction occurring
after the date hereof (such redemption price being the "Redemption Price"), and
the Company may, at its option, by action of the Company's Board of Directors,
pay the Redemption Price either in shares of Company Common Stock (based on the
"current market price", as defined in Section 11(d) hereof, of the shares of
Company Common Stock at the time of redemption) or cash. Subject to the
foregoing, the redemption of the Rights may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish.

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

     SECTION 24. Notice of Certain Events. (a) In case the Company shall
propose, at any time after the Distribution Date, (i) to pay any dividend
payable in stock of any class to the holders of Preferred Stock or to make any
other distribution to the holders of Preferred Stock


<PAGE>   35


                                       33

(other than a regular quarterly cash dividend out of earnings or retained
earnings of the Company), (ii) to offer to the holders of Preferred Stock rights
or warrants to subscribe for or to purchase any additional shares of Preferred
Stock or shares of stock of any class or any other securities, rights or
options, (iii) to effect any reclassification of the Preferred Stock (other than
a reclassification involving only the subdivision of outstanding shares of
Preferred Stock), (iv) to effect any consolidation or merger into or with any
other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), or to effect any sale or other transfer (or
to permit one or more of its Subsidiaries to effect any sale or other transfer),
in one or more transactions, of more than 50% of the assets or earning power of
the Company and its Subsidiaries (taken as a whole) to any other Person or
Persons (other than the Company and/or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(o) hereof), or (v) to effect
the liquidation, dissolution or winding up of the Company, then, in each such
case, the Company shall give to each holder of a Rights Certificate (or, prior
to the Distribution Date, to each holder of certificates for Company Common
Stock), to the extent feasible and in accordance with Section 25 hereof, a
notice of such proposed action, which shall specify the record date for the
purposes of such stock dividend, distribution of rights or warrants, or the date
on which such reclassification, consolidation, merger, sale, transfer,
liquidation, dissolution, or winding up is to take place and the date of
participation therein by the holders of the shares of Preferred Stock, if any
such date is to be fixed, and such notice shall be so given in the case of any
action covered by clause (i) or (ii) above at least twenty (20) days prior to
the record date for determining holders of the shares of Preferred Stock for
purposes of such action, and in the case of any such other action, at least
twenty (20) days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of the shares of Preferred Stock
whichever shall be the earlier; provided, however, no such notice shall be
required pursuant to this Section 24, if any Subsidiary of the Company effects a
consolidation or merger with or into, or effects a sale or other transfer of
assets or earning power to, any other Subsidiary of the Company.

     (b) In case any of the events set forth in Section 11(a)(ii)
hereof shall occur, then, in any such case, the Company shall as soon as
practicable thereafter give to each holder of a Rights Certificate, to the
extent feasible and in accordance with Section 25 hereof, a notice of the
occurrence of such event, which shall specify the event and the consequences of
the event to holders of Rights under Section 11(a)(ii) hereof.

     SECTION 25. Notices. All notices and other communications provided for
hereunder shall, unless otherwise stated herein, be in writing (including by
facsimile, telex, telegram or cable) and mailed or sent or delivered, if to the
Company, at its address at:

     Attention: Client Administration

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

     SECTION 26. Supplements and Amendments. Prior to the Distribution Date and
subject to the penultimate sentence of this Section 26, the Company and the
Rights Agent shall, if the Company so directs, supplement or amend any provision
of this Agreement without the approval of any holders of certificates
representing shares of Company Common Stock. From and after the Distribution
Date and subject to the penultimate sentence of this Section 26, the Company and
the Rights Agent shall, if the Company so directs, supplement or amend this
Agreement without the approval of any holders of Rights Certificates 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 change or
supplement the provisions hereunder in any manner which the Company may deem
necessary or desirable and which shall not adversely affect the interests of the
holders of Rights Certificates (other than an Acquiring Person or an Affiliate
or Associate of an Acquiring Person); provided, however, that this Agreement may
not be supplemented or amended to lengthen, pursuant to clause (iii) of this
sentence, (A) subject to Section 30 hereof, a time period relating to when the
Rights may be redeemed at such time as the Rights are not then redeemable, or
(B) any other time period, including, without limitation, a time period relating
to when the Rights may be redeemed at such time as the Rights are then
redeemable, unless such lengthening is for the purpose of protecting, enhancing
or clarifying the rights of, and/or the benefits to, the holders of Rights. Upon
the delivery of a certificate from an appropriate officer of the Company which
states that the proposed supplement or amendment is in compliance with the terms
of this Section 26, the Rights Agent shall execute such supplement or amendment.
Prior to the Distribution Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of Company Common Stock.

     SECTION 27. Successors. All the covenants and provisions of this Agreement
by or for the benefit of the Company or the Rights Agent shall bind and inure to
the benefit of their respective successors and assigns hereunder.

     SECTION 28. Determinations and Actions by the Board of Directors, etc. For
all purposes of this Agreement, any calculation of the number of shares of
Company Common Stock outstanding at any particular time, including for purposes
of determining the particular


<PAGE>   37


                                       35

percentage of such outstanding shares of Company Common Stock of which any
Person is the Beneficial Owner, shall be made in accordance with the last
sentence of Rule 13d-3(d)(1)(i) of the Exchange Act Regulations as in effect on
the date hereof. Except as otherwise specifically provided herein, the Board of
Directors of the Company shall 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 (i) to interpret the provisions of this
Agreement, and (ii) to make all determinations deemed necessary or advisable for
the administration of this Agreement. All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith shall (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 or any member thereof to any
liability to the holders of the Rights. Any reference herein to action by the
Board of Directors of the Company refers to action by such vote as is required
by the Restated Articles of Incorporation or By-laws of the Company or otherwise
required by applicable law.

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

     SECTION 30. Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions of this Agreement shall remain in full
force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Company's Board
of Directors determines in its good faith judgment that severing the invalid
language from this Agreement would adversely affect the purpose or effect of
this Agreement and the Rights shall not then be redeemable, the right of
redemption set forth in Section 23 hereof shall be reinstated and shall not
expire until the Close of Business on the tenth Business Day following the date
of such determination by the Company's Board of Directors.

     SECTION 31. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be governed by, and construed in accordance
with, the laws of the State of Michigan applicable to contracts executed in and
to be performed entirely in such State.

     SECTION 32. Counterparts. This Agreement may be executed (including by
facsimile) in one or more counterparts, and by the different parties hereto in
separate


<PAGE>   38


                                       36

counterparts, each of which when executed shall be deemed to be an original, but
all of which taken together shall constitute one and the same instrument.

     SECTION 33. Descriptive Headings. The headings contained in this Agreement
are for descriptive purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     SECTION 34. Exchange. (a) (i) The Company may, at its option, at any time
after any person becomes an Acquiring Person, upon resolution adopted by the
Company's Board of Directors, exchange all or part of the then outstanding and
exercisable Rights (which shall not include Rights that have become void
pursuant Section 7(e)) for shares of Company Common Stock at an exchange ratio
of one share of Company Common Stock per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such exchange ratio being hereinafter referred to as the
"Section 34(a)(i) Exchange Ratio"). Notwithstanding the foregoing, the Company
may not effect such exchange at any time after any Person (other than the
Company, any Subsidiary of the Company, any employee benefit plan maintained by
the Company or any of its Subsidiaries, or any trustee or fiduciary with respect
to such plan acting in such capacity), together with all Affiliates and
Associates of such Person, becomes the Beneficial Owner of 50% or more of the
shares of Company Common Stock then outstanding.

     (ii) The Company may, at its option, at any time after any person becomes
an Acquiring Person, upon resolution adopted by the Company's Board of
Directors, exchange all or part of the then outstanding and exercisable Rights
(which shall not include Rights that have become void pursuant to Section 7(e))
for shares of Company Common Stock at an exchange ratio specified in the
following sentence, as appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof. Subject to such
adjustment, each Right may be exchanged for that number of shares of Company
Common Stock obtained by dividing the Adjustment Spread (as defined below) by
the then current market price (determined pursuant to Section 11(d)) per Unit of
Preferred Stock on the earlier of (i) the date on which any Person becomes an
Acquiring Person and (ii) the date on which a tender or exchange offer by any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan maintained by the Company or any of its Subsidiaries or any trustee
or fiduciary with respect to such plan acting in such capacity) is first
published or sent or given within the meaning of Rule 14d-4(a) of the Exchange
Act Regulations or any successor rule, if upon consummation thereof such Person
would be the Beneficial Owner of 30% or more of the shares of Company Common
Stock then outstanding (such exchange ratio being the "Section 34(a)(ii)
Exchange Ratio"). The "Adjustment Spread" shall equal (x) the aggregate market
price on the date of such event of the number of Adjustment Shares determined
pursuant to Section 11(a)(ii), minus (y) the Purchase Price. Notwithstanding the
foregoing, the Company may not effect such exchange at any time after any Person
(other than the Company, any Subsidiary of the Company, any employee benefit
plan maintained by the Company or any of its Subsidiaries, or any trustee or
fiduciary with respect to such plan acting in such capacity), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the shares of the Company Common Stock then outstanding.

                                       37

     (b) Immediately upon the action of the Company's Board of Directors
ordering the exchange of any Rights pursuant to Section 34(a) and without any
further action and without any notice, the right to exercise such Rights shall
terminate and the only right thereafter of a holder of such Rights shall be to
receive that number of shares of Company Common Stock equal to the number of
such Rights held by such holder multiplied by the Section 34(a)(i) Exchange
Ratio or Section 34(a)(ii) Exchange Ratio, as the case may be (in each case, the
"Exchange Shares"). The Company shall promptly give public notice of any such
exchange; provided, however, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange. The Company promptly
shall mail a notice of any such exchange to all of the holders of such Rights at
their last addresses as they appear upon the registry books of the Rights Agent.
Any notice that is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange
shall state the method by which the exchange of shares of Company Common Stock
for Rights will be effected and, in the event of any partial exchange, the
number of Rights that will be exchanged. Any partial exchange shall be effected
pro rata based on the number of Rights (other than Rights that have become void
pursuant to Section 7(e)) held by each holder of Rights.

     (c) In the event that the number of shares of Company Common Stock which
are authorized by the Company's Restated Articles of Incorporation, and neither
outstanding nor reserved for issuance for purposes other than upon exercise of
the Rights, are not sufficient to permit any exchange of Rights as contemplated
in accordance with this Section 34, the Company shall take all such action as
may be necessary to authorize additional shares of Company Common Stock for
issuance upon exchange of the Rights or make adequate provision to substitute
(1) such number of Units of Preferred Stock which is the product of such
Exchange Shares multiplied by

                                    (1 - A )
                                        ---
                                         B
   where:

         A =      the number of shares of Company Common Stock
                  authorized and neither outstanding nor reserved for
                  issuance for purposes other than upon exercise of the
                  Rights; and

         B =      the number of shares of Company Common Stock
                  sufficient to permit any exchange of Rights as
                  contemplated in accordance with this Section 34,

   (2) cash, (3) other equity securities of the Company, (4) debt securities of
   the Company, (5) other assets or (6) any combination of the foregoing, having
   an aggregate value equal to the Adjustment Spread, where such aggregate value
   has been determined by the Company's Board of Directors; provided, however,
   that the Company may substitute the consideration specified in clauses (2) -
   (6) above only in the event that the number of shares of Preferred Stock
   authorized by the Company's Restated Articles of Incorporation is inadequate
   for the purposes hereof.

                                       38

     (d) The Company shall not be required to issue fractions of Company Common
Stock or Units of Preferred Stock, as the case may be, or to distribute
certificates that evidence fractional Company Common Stock or Units. In lieu of
fractional Company Common Stock or Units, the Company may pay to the registered
holders of Rights Certificates at the time such Rights are exchanged as herein
provided an amount in cash equal to the same fraction of the current market
price (determined pursuant to Section 11(d)) of one share of Company Common
Stock or Unit of Preferred Stock, as the case may be.

         This certifies that _____________________, or registered assigns, is
the registered holder of the number of Rights set forth above, each of which
entitles the registered holder thereof, subject to the terms and conditions of
the Amended and Restated Rights Agreement dated as of April 27, 2000 (the

surrender of this Rights Certificate with the Election to Purchase and related
certificate duly executed. The number of Rights evidenced by this Rights
Certificate (and the number of Units which may be purchased upon exercise
thereof) set forth above, and the Purchase Price per Unit set forth above shall
be subject to adjustment in certain events as provided in the Rights Agreement.

         Upon the occurrence of a Section 11(a)(ii) Event, if the Rights
evidenced by this Rights Certificate are beneficially owned by an Acquiring
Person or an Affiliate or Associate of any such Acquiring Person or, under
certain circumstances described in the Amended Rights Agreement, a transferee of
any such Acquiring Person, Associate or Affiliate, such Rights shall become null
and void and no holder hereof shall have any right with respect to such Rights
from and after the occurrence of such Section 11(a)(ii) Event.

         In certain circumstances described in the Amended Rights Agreement, the
rights evidenced hereby may entitle the registered holder thereof to purchase
capital stock of an entity other than the Company or receive common stock, cash
or other assets, all as provided in the Amended Rights Agreement.

         This Rights Certificate is subject to all of the terms and conditions
of the Amended Rights Agreement, which terms and conditions are hereby
incorporated herein by reference and made a part hereof and to which Amended
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates. Copies of
the Amended Rights Agreement are on file at the principal office of the Company
and are available from the Company upon written request.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the office of the Rights Agent designated for such purpose,
may be exchanged for another Rights Certificate or Rights Certificates of like
tenor and date evidencing an aggregate number of Rights equal to the aggregate
number of Rights evidenced by the Rights Certificate or Rights Certificates
surrendered. If this Rights Certificate shall be exercised in part, the
registered holder shall be entitled to receive, upon surrender hereof, another
Rights Certificate or Rights Certificates for the number of whole Rights not
exercised.

         Subject to the provisions of the Amended Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company under certain
circumstances at its option at a redemption price of $.01 per Right, payable at
the Company's option in cash or in common stock of the Company, subject to
adjustment in certain events as provided in the Amended Rights Agreement.

         No fractional shares of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a share of Preferred Stock), but in
lieu thereof a cash payment will be made, as provided in the Amended Rights
Agreement.

         No holder of this Rights Certificate, as such, shall be entitled to
vote or receive dividends or be deemed for any purpose the holder of Preferred
Stock or of any other securities which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Amended Rights Agreement or
herein be construed to confer upon the holder hereof, as such, any of the rights
of a shareholder of the Company or any right to vote for the election of
directors or upon any matter submitted to shareholders at any meeting thereof,
or to give or withhold consent to any corporate action, or to receive notice of
meetings or other actions affecting shareholders (except as provided in the
Amended Rights Agreement), or to receive dividends or subscription rights, or

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK

         On May 4, 1990, Detrex Corporation (the "Company") entered into a
stockholder rights agreement (the "Rights Agreement") between the Company and
NBD Bank, N.A., as Rights Agent. Pursuant to the Rights Agreement, the Board of
Directors of the Company declared, effective May 4, 1990, a distribution of one
Right for each outstanding share of Common Stock, par value $2.00 per share (the
"Company Common Stock"), to shareholders of record at the close of business on
May 15, 1990 and for each share of Company Common Stock issued (including shares
distributed from Treasury) by the Company thereafter and prior to the
Distribution Date. On April 27, 2000, the Board of Directors of the Company
authorized the renewal of the Rights Agreement which was due to expire on May 4,
2000. The Company entered into an Amended and Restated Rights Agreement (the
"Amended Rights Agreement"), dated as of April 27, 2000, between the Company and
State Street Bank & Trust Company, as Rights Agent.

         Each Right entitles the registered holder subject to the terms of the
Amended Rights Agreement, to purchase from the Company one one-hundredth of a
share (a "Unit") of Series A Preferred Stock, par value $2.00 per share (the
"Preferred Stock"), at a Purchase Price of $30.00 per Unit, subject to
adjustment. The Purchase Price is payable in cash or by certified or bank check
or money order payable to the order of the Company or by wire transfer of
immediately payable funds to the account of the Company (provided that a notice
of such wire transfer is given by the holder of the related Right to the Rights
Agent).

         The description and terms of the Rights are set forth in the Amended
Rights Agreement. Copies of the Amended Rights Agreement and the Certificate of
Designations for the Preferred Stock have been filed with the Securities and
Exchange Commission as exhibits to a Registration Statement on Form 8-A dated
May 4, 1990, as amended on April 27, 2000 (the "Form 8-A"). Copies of the
Amended Rights Agreement and the Certificate of Designations are available free
of charge from the Company. This summary description of the Rights and the
Preferred Stock does not purport to be complete and is qualified in its entirety
by reference to all the provisions of the Amended Rights Agreement and the
Certificate of Designations, including the definitions therein of certain terms,
which Amended Rights Agreement and Certificate of Designations are incorporated
herein by reference.

The Amended Rights Agreement

         Initially the Rights will attach to all certificates representing
shares of outstanding Company Common Stock, and no separate Rights Certificates
will be distributed. The Rights will separate from the Company Common Stock and
the Distribution Date will occur upon the earlier of (i) 10 business days
following a public announcement (the date of such announcement being the "Stock
Acquisition Date") that a person or group of affiliated or associated persons
(other than the Company, any Subsidiary of the Company or any employee benefit
plan of the Company or such Subsidiary) (an "Acquiring Person") has acquired,
obtained the right to acquire, or otherwise obtained beneficial ownership of 15%
or more of the then outstanding


<PAGE>   50


                                        2

shares of Company Common Stock, or (ii) 10 business days (or such later date as
may be determined by action of the Board of Directors prior to such time as any
person becomes an Acquiring Person) following the commencement of a tender offer
or exchange offer that would result in a person or group beneficially owning 30%
or more of the then outstanding shares of Company Common Stock. Until the
Distribution Date, (i) the Rights will be evidenced by Company Common Stock
certificates and will be transferred with and only with such Company Common
Stock certificates, (ii) new Company Common Stock certificates issued after May
15, 1990 (also including shares distributed from Treasury) will contain a
notation incorporating the Amended Rights Agreement by reference and (iii) the
surrender for transfer of any certificates representing outstanding Company
Common Stock will also constitute the transfer of the Rights associated with the
Company Common Stock represented by such certificates.

         The Rights are not exercisable until the Distribution Date and will
expire at the close of business on May 4, 2010 unless earlier redeemed by the
Company as described below.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of Company Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights.

         In the event that (i) the Company is the surviving corporation in a
merger with an Acquiring Person and shares of Company Common Stock shall remain
outstanding, (ii) a Person becomes an Acquiring Person, (iii) an Acquiring
Person engages in one or more "self-dealing" transactions as set forth in the
Amended Rights Agreement, or (iv) during such time as there is an Acquiring
Person, an event occurs which results in such Acquiring Person's ownership
interest being increased by more than 1% (e.g., by means of a reverse stock
split or recapitalization) (each such event being a "Section 11(a)(ii) Event"),
then, in each such case, each holder of a Right will thereafter have the right
to receive, upon exercise, Company Common Stock (or, in certain circumstances,
Units of Preferred Stock, cash, property or other securities of the Company)
having a value equal to two times the exercise price of the Right. The exercise
price is the Purchase Price multiplied by the number of Units of Preferred Stock
issuable upon exercise of a Right prior to the events described in this
paragraph. Notwithstanding any of the foregoing, following the occurrence of any
of the events set forth in this paragraph, all Rights that are, or (under
certain circumstances specified in the Amended Rights Agreement) were,
beneficially owned by any Acquiring Person will be null and void.

         In the event that, at any time following the Stock Acquisition Date,
(i) the Company is acquired in a merger or other business combination
transaction and the Company is not the surviving corporation (other than a
merger described in the preceding paragraph), (ii) any Person consolidates or
merges with the Company and all or part of the Company Common Stock is converted
or exchanged for securities, cash or property of any other Person or (iii) 50%
or more of the Company's assets or earning power is sold or transferred, each
holder of a Right (except Rights which previously have been voided as described
above) shall thereafter have the right to receive, upon exercise, common stock
of the ultimate parent of the Acquiring Person having a value equal to two times
the exercise price of the Right.



<PAGE>   51


                                        3

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

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. The Company is not required to issue fractional Units. In lieu thereof,
an adjustment in cash may be made based on the market price of the Preferred
Stock prior to the date of exercise.

         At any time until ten business days following the Stock Acquisition
Date, the Company's Board of Directors may redeem the Rights in whole, but not
in part, at a price of $.01 per Right (the "Redemption Price"), payable, at the
election of the Company's Board of Directors, in cash or shares of Company
Common Stock. Immediately upon the action of the Company's Board of Directors
ordering the redemption of the Rights, the Rights will terminate and the only
right of the holders of Rights will be to receive the Redemption Price.

         The Board of Directors, at its option, may exchange each Right for (i)
one share of Company Common Stock or (ii) such number of shares of Company
Common Stock (or, in certain circumstances, Units of Preferred Stock, cash,
property or other securities of the Company) as will equal (x) the difference
between the aggregate market price of the number of shares of Company Common
Stock to be received upon a Section 11(a)(ii) Event and the purchase price set
forth in the Amended Rights Agreement, divided by (y) the market price per share
of Company Common Stock upon a Section 11(a)(ii) Event.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to shareholders or to the Company, shareholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Units of Preferred Stock (or other consideration).

         Any of the provisions of the Amended Rights Agreement may be amended
without the approval of the holders of Company Common Stock at any time prior to
the Distribution Date. After the Distribution Date, the provisions of the
Amended Rights Agreement may be amended in order to cure any ambiguity, defect
or inconsistency, to make changes which do not adversely affect the interests of
holders of Rights (excluding the interests of any Acquiring Person), or to
shorten or lengthen any time period under the Amended Rights Agreement;
provided, however, that no amendment to adjust the time period governing
redemption shall be made at such time as the Rights are not redeemable.

Description of Preferred Stock

         The Units of Preferred Stock that may be acquired upon exercise of the
Rights will be nonredeemable and subordinate to any other shares of preferred
stock that may be issued by the Company.

         Each Unit of Preferred Stock will have a minimum preferential quarterly
dividend rate of $.30 per Unit but will, in any event, be entitled to a dividend
equal to the per share dividend declared on the Company Common Stock.

         In the event of liquidation, the holder of a Unit of Preferred Stock
will receive a preferred liquidation payment equal to the greater of $.05 per
Unit or the per share amount paid in respect of a share of Company Common Stock.

         Each Unit of Preferred Stock will have one one-hundredth of a vote,
voting together with the Company Common Stock. The approval of holders a
majority of the Units of Preferred Stock, voting as a separate class, is
necessary in order for the Company to (i) create a class of stock with a
superior rank as to dividends or assets or (ii) sell, lease, exchange, assign,
transfer or convey all or substantially all the property and assets of the
Company. The approval of holders of two-thirds of such Units, voting as a
separate class, is necessary in order for the Company to merge or consolidate
into or with any other corporation unless such approval is not required by law,
the rights of such holders are not adversely affected thereby and the
corporation resulting from such merger or consolidation will not have, after
such merger or consolidation, any securities ranking prior to the Units of
Preferred Stock as to dividends or assets of the merged or consolidated
corporation.

         In the event of any merger, consolidation or other transaction in which
shares of Company Common Stock are exchanged, each Unit of Preferred Stock will
be entitled to receive the per share amount paid in respect of each share of
Company Common Stock.

         The rights of holders of the Preferred Stock to dividends and,
liquidation, and in the event of mergers and consolidations, are protected by
customary antidilution provisions.

         Because of the nature of the Preferred Stock's dividend and liquidation
rights, and except for its diminished voting rights, the economic value of one
Unit of Preferred Stock that may be acquired upon the exercise of each Right
should approximate the economic value of one share of Company Common Stock.

                           CERTIFICATE OF DESIGNATIONS

                                       of

                            SERIES A PREFERRED STOCK

                                       of

                               DETREX CORPORATION
                         (Pursuant to Section 302 of the
                       Michigan Business Corporation Act)

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

         Detrex Corporation, a Michigan corporation (the "Corporation") hereby
certifies that the following resolution was adopted by the Board of Directors of
the Corporation as required by Section 302 of the Michigan Business Corporation
Act, Mich. Comp. Laws Ann. ss. 450.1302 at a meeting duly called and held on May
1, 1990:

         RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation by Article IV of its Restated Articles of
Incorporation and in accordance with the provisions of Section 302 of the
Michigan Business Corporation Act, said Board of Directors does hereby create,
authorize and provide for the issuance of a series of Preferred Stock, par value
$2.00 per share, of the Corporation having the following voting powers,
designation, preferences and relative, participating, optional and other special
rights, and qualifications, limitations and restrictions in addition to those
set forth in said Article IV:

         Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Preferred Stock" and the number of shares constituting
such series shall be 100,000.

         Section 2. Dividends and Distributions. (A) Subject to the prior and
superior rights of the holders of any shares of any other series of Preferred
Stock or any other shares of preferred stock of the Corporation ranking prior
and superior to the shares of Series A Preferred Stock with respect to
dividends, each holder of one one-hundredth (1/100) of a share (a "Unit") of
Series A Preferred Stock shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for that purpose, (i)
quarterly dividends payable in cash on the first day of January, April, July and
October in each year (each such date being a "Quarterly Dividend Payment Date"),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of such Unit of Series A Preferred Stock, in an amount per Unit (rounded to the
nearest cent) equal to the greater of (a) $.30 or (b) subject to the provision
for adjustment hereinafter set forth, the aggregate per share amount of all cash
dividends declared on shares of the Common Stock since the immediately preceding
Quarterly Dividend Payment Date, or, with respect to the first Quarterly
Dividend Payment Date, since the first issuance of a Unit of Series A Preferred
Stock, and (ii) subject to the provision for adjustment hereinafter set forth,
quarterly distributions (payable in kind) on each Quarterly Dividend Payment
Date in an amount per Unit equal to the


<PAGE>   54


                                        2

aggregate per share amount of all non-cash dividends or other distributions
(other than a dividend payable in shares of Common Stock or a subdivision of the
outstanding shares of Common Stock, by reclassification or otherwise) declared
on shares of Common Stock since the immediately preceding Quarterly Dividend
Payment Date, or with respect to the first Quarterly Dividend Payment Date,
since the first issuance of a Unit of Series A Preferred Stock. In the event
that the Corporation shall at any time after May 4, 1990 (the "Rights
Declaration Date") (i) declare any dividend on outstanding shares of Common
Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of
Common Stock or (iii) combine outstanding shares of Common Stock into a smaller
number of shares, then in each such case the amount to which the holder of a
Unit of Series A Preferred Stock was entitled immediately prior to such event
pursuant to the preceding sentence shall be adjusted by multiplying such amount
by a fraction the numerator of which shall be the number of shares of Common
Stock that are outstanding immediately after such event and the denominator of
which shall be the number of shares of Common Stock that were outstanding
immediately prior to such event.

         (B)  The Corporation shall declare a dividend or distribution on Units
of Series A Preferred Stock as provided in paragraph (A) above immediately after
it declares a dividend or distribution on the shares of Common Stock (other than
a dividend payable in shares of Common Stock); provided, however, that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $.30 per Unit on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

         (C)  Dividends shall begin to accrue and shall be cumulative on each
outstanding Unit of Series A Preferred Stock from the Quarterly Dividend Payment
Date next preceding the date of issuance of such Unit of Series A Preferred
Stock, unless the date of issuance of such Unit is prior to the record date for
the first Quarterly Dividend Payment Date, in which case, dividends on such Unit
shall begin to accrue from the date of issuance of such Unit, or unless the date
of issuance is a Quarterly Dividend Payment Date or is a date after the record
date for the determination of holders of Units of Series A Preferred Stock
entitled to receive a quarterly dividend and before such Quarterly Dividend
Payment Date, in either of which events such dividends shall begin to accrue and
be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
dividends shall not bear interest. Dividends paid on Units of Series A Preferred
Stock in an amount less than the aggregate amount of all such dividends at the
time accrued and payable on such Units shall be allocated pro rata on a
unit-by-unit basis among all Units of Series A Preferred Stock at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of Units of Series A Preferred Stock entitled to receive payment of a
dividend or distribution declared thereon, which record date shall be no more
than 30 days prior to the date fixed for the payment thereof.

Section 3. Certain Restrictions. (A) Whenever quarterly dividends or other
dividends or distributions payable on Units of Series A Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared,


<PAGE>   55


                                        3

on outstanding Units of Series A Preferred Stock shall have been paid in full,
the Corporation shall not

              (i)   declare or pay dividends on, make any other distributions
         on, or redeem or purchase or otherwise acquire for consideration any
         shares of junior stock;

              (ii)  declare or pay dividends on or make any other distributions
         on any shares of parity stock, except dividends paid ratably on Units
         of Series A Preferred Stock and shares of all such parity stock on
         which dividends are payable or in arrears in proportion to the total
         amounts to which the holders of such Units and all such shares are then
         entitled;

              (iii) redeem or purchase or otherwise acquire for consideration
         shares of any parity stock, provided, however, that the Corporation may
         at any time redeem, purchase or otherwise acquire shares of any such
         parity stock in exchange for shares of any junior stock;

              (iv)  purchase or otherwise acquire for consideration any Units of
         Series A Preferred Stock, except in accordance with a purchase offer
         made in writing or by publication (as determined by the Board of
         Directors) to all holders of such Units.

         (B)  The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 3,
purchase or otherwise acquire such shares at such time and in such manner.

         Section 4. Reacquired Shares. Any Units of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled automatically upon the acquisition thereof. All
such Units shall, upon their cancellation, become authorized but unissued Units
of Preferred Stock and may be reissued as part of a new series of Preferred
Stock to be created by resolution or resolutions of the Board of Directors,
subject to the conditions and restrictions on issuance set forth herein.

         Section 5. Liquidation, Dissolution or Winding Up. (A) Upon any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, no distribution shall made (i) to the holders of shares of junior
stock unless the holders of Units of Series A Preferred Stock shall have
received, subject to adjustment as hereinafter provided in paragraph (B), the
greater of either (a) $.05 per Unit plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not earned or declared, to the
date of such payment, or (b) the amount per Unit equal to the aggregate per
share amount to be distributed to holders of shares of Common Stock, or (ii) to
the holders of shares of parity stock, unless simultaneously therewith
distributions are made ratably on Units of Series A Preferred Stock and all
other shares of such parity stock in proportion to the total amounts to which
the holders of Units of Series A Preferred Stock are entitled under clause
(i)(a) of this sentence and to which the holders of shares of such parity stock
are entitled, in each case upon such liquidation, dissolution or winding up.


<PAGE>   56


                                        4

         (B)  In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on outstanding shares of Common Stock
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common
Stock, or (iii) combine outstanding shares of Common Stock into a smaller number
of shares, then in each such case the aggregate amount to which holders of Units
of Series A Preferred Stock were entitled immediately prior to such event
pursuant to clause (i)(b) of paragraph (A) of this Section 5 shall be adjusted
by multiplying such amount by a fraction the numerator of which shall be the
number of shares of Common Stock that are outstanding immediately after such
event and the denominator of which shall be the number of shares of Common Stock
that were outstanding immediately prior to such event.

           Section 6. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or converted into other stock or
securities, cash and/or any other property, then in any such case Units of
Series A Preferred Stock shall at the same time be similarly exchanged for or
converted into an amount per Unit (subject to the provision for adjustment
hereinafter set forth) equal to 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 converted or exchanged. In the event the
Corporation shall at any time after the Rights Declaration Date (i) declare any
dividend on outstanding shares of Common Stock payable in shares of Common
Stock, (ii) subdivide outstanding shares of Common Stock, or (iii) combine
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the immediately preceding sentence with respect to the
exchange or conversion of Units of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction the numerator of which shall be the number
of shares of Common Stock that are outstanding immediately after such event and
the denominator of which shall be the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 7.  Redemption.  The Units of Series A Preferred Stock shall
not be redeemable.

         Section 8. Ranking. The Units of Series A Preferred Stock shall rank
junior to any other class of preferred stock that hereafter may be issued by the
Corporation as to the payment of dividends and the distribution of assets,
unless the terms of any such series or class shall provide otherwise.

         Section 9. Amendment. The Articles, including, without limitation, this
resolution, shall not hereafter be amended, either directly or indirectly, or
through merger or consolidation with another corporation, in any manner that
would alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders a majority or more of the outstanding Units of Series A Preferred
Stock, voting separately as a class.

         Section 10. Fractional Shares. The Series A Preferred Stock may be
issued in Units or other fractions of a share, which Units or fractions shall
entitle the holder, in proportion to such holder's fractional shares, to
exercise voting rights, receive dividends, participate in distributions and to
have the benefit of all other rights holders of Series A Preferred Stock.


<PAGE>   57


                                        5

         Section 11.  Certain Definitions.  As used herein with respect to the
Series A Preferred Stock, the following terms shall have the following meanings:

                   (A)  The term "Common Stock" shall mean the class of stock
         designated as the common stock, par value $2.00 per share, of the
         Corporation at the date hereof or any other class of stock resulting
         from successive changes or reclassification of the common stock.

                   (B)  The term "junior stock" (i) as used in Section 3 shall
         mean the Common Stock and any other class or series of capital stock of
         the Corporation hereafter authorized or issued over which the Series A
         Preferred Stock has preference or priority as to the payment of
         dividends and (ii) as used in Section 5, shall mean the Common Stock
         and any other class or series of capital stock of the Corporation over
         which the Series A Preferred Stock has preference or priority in the
         distribution of assets on any liquidation, dissolution or winding up of
         the Corporation.

                   (C)  The term "parity stock" (i) as used in Section 3, shall
         mean any class or series of stock of the Corporation hereafter
         authorized or issued ranking pari passu with the Series A Preferred
         Stock as to dividends and (ii) as used in Section 5, shall mean any

         IN WITNESS WHEREOF, this Certificate of Designations is executed on

                DETREX CORPORATION RENEWS STOCKHOLDER RIGHTS PLAN

         Southfield, Michigan - April 27, 2000 - Detrex Corporation (NASDAQ:
DTRX), a diversified manufacturer of a broad range of chemicals and allied
products for manufacturing and service industries, announced today that its
Board of Directors has renewed the Company's shareholder rights plan designed to
protect its shareholders from unsolicited, coercive takeover proposals.
         An amended and restated plan was adopted in the normal course of
updating and extending the shareholder rights plan, which was scheduled to
expire on May 4, 2000, and not in response to any acquisition proposal. The
expiration date of the rights plan has been extended to May 4, 2010.
         The amended plan reflects prevailing shareholder rights plan terms,
including a cashless exchange of the rights at the option of the Board of
Directors of the Company.
