ITEM 1.  DESCRIPTION OF SECURITIES TO BE REGISTERED

     On March 11, 1999, the Board of Directors of Trinity Industries, Inc. (the
"Company") declared a dividend distribution of one Right for each outstanding
share of the Company's common stock, $1.00 par value (the "Common Stock"), to
stockholders of record at the close of business on April 27, 1999. Each Right
entitles the registered holder to purchase from the Company one one-hundredth
(1/100) of a share of Series A Preferred Stock, par value $1.00 (the "Preferred
Stock"), at a Purchase Price of $200.00 per one one-hundredth (1/100) of a
share, subject to adjustment. The description and terms of the Rights are set
forth in a Rights Agreement (the "Rights Agreement") between the Company and
The Bank of New York, as Rights Agent (the "Rights Agent").

     Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock upon the earlier
of (i) ten (10) business days following a public announcement that a person or
group of affiliated or associated persons (an "Acquiring Person") has acquired,
or obtained the right to acquire, beneficial ownership of twelve percent (12%)
or more of the outstanding shares of Common Stock (the "Stock Acquisition
Date"), or (ii) ten (10) business days (or such later date as the Board of
Directors shall determine) following the commencement of a tender or exchange
offer that would result in a person or group beneficially owning twelve percent
(12%) or more of such outstanding shares of Common Stock. The date the Rights
separate is referred to as the "Distribution Date."

     Until the Distribution Date, (i) the Rights will be evidenced by the
Common Stock certificates and will be transferred with and only with such
Common Stock certificates, (ii) new Common Stock certificates issued after
April 27, 1999 will contain a notation incorporating the Rights Agreement by
reference, and (iii) the surrender for transfer of any certificates for Common
Stock outstanding will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificates. Pursuant to the Rights
Agreement, the Company reserves the right to require prior to the occurrence of
a Triggering Event (as defined below) that, upon any exercise of Rights, a
number of Rights be exercised so that only whole shares of Preferred Stock will
be issued.

     The Rights are not exercisable until the Distribution Date and will expire
at the close of business on April 27, 2009, 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 the Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates will represent the Rights. Except in connection with shares of
Common Stock issued or sold pursuant to 

<PAGE>   3

the exercise of stock options under any employee plan or arrangements, or upon
the exercise, conversion or exchange of securities hereafter issued by the
Company, or as otherwise determined by the Board of Directors, only shares of
Common Stock issued prior to the Distribution Date will be issued with Rights.

     In the event that (i) the Company is the surviving corporation in a merger
or other business combination with an Acquiring Person (or any associate or
affiliate thereof) and its Common Stock remains outstanding and unchanged, (ii)
any person shall acquire beneficial ownership of more than twelve percent (12%)
of the outstanding shares of Common Stock (except pursuant to (A) certain
consolidations or mergers involving the Company or sales or transfers of the
combined assets, cash flow or earning power of the Company and its subsidiaries
or (B) an offer for all outstanding shares of Common Stock at a price and upon
terms and conditions which the Board of Directors determines to be in the best
interests of the Company and its stockholders), or (iii) there occurs a
reclassification of securities, a recapitalization of the Company or any of
certain business combinations or other transactions (other than certain
consolidations and mergers involving the Company and sales or transfers of the
combined assets, cash flow or earning power of the Company and its
subsidiaries) involving the Company or any of its subsidiaries which has the
effect of increasing by more than one percent (1%) the proportionate share of
any class of the outstanding equity securities of the Company or any of its
subsidiaries beneficially owned by an Acquiring Person (or any associate or
affiliate thereof), each holder of a Right (other than the Acquiring Person and
certain related parties) will thereafter have the right to receive, upon
exercise, Common Stock (or, in certain circumstances, cash, property or other
securities of the Company) having a value equal to two times the Purchase Price
of the Right. Notwithstanding any of the foregoing, following the occurrence of
any of the events described in this paragraph, all Rights that are, or (under
certain circumstances specified in the Rights Agreement) were, beneficially
owned by any Acquiring Person will be null and void. The events described in
this paragraph are referred to as "Flip-in Events."

     For example, at a Purchase Price of $200 per Right, each Right not owned
by an Acquiring Person (or by certain related parties or transferees) following
an event set forth in the preceding paragraph would entitle its holder to
purchase $400 worth of Common Stock (or other consideration, as noted above)
for $200. Assuming that the Common Stock had a per share market price of $80 at
such time, the holder of each valid Right would be entitled to purchase five
shares of Common Stock for $200.

     In the event that, at any time following the Stock Acquisition Date, (i)
the Company shall enter into a merger or other business combination transaction
in which the Company is not the surviving corporation, (ii) the Company is the
surviving corporation in a consolidation, merger or similar transaction
pursuant to which all or part of the outstanding shares of Common Stock are
changed into or exchanged for stock or other securities of any other person or
cash or any other property or (iii) more than 


                                      -2-
<PAGE>   4

50% of the combined assets, cash flow or earning power of the Company and its
subsidiaries is sold or transferred (in each case other than certain
consolidations with, mergers with and into, or sales of assets, cash flow or
earning power by or to subsidiaries of the Company as specified in the Rights
Agreement), each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, common stock of the acquiring company having a value equal to two
times the Purchase Price of the Right. The events described in this paragraph
are referred to as "Flip-over Events." Flip-in Events and Flip-over Events are
referred to collectively as "Triggering Events."

     The Purchase Price payable, the number and kind of shares covered by each
Right and the number of Rights outstanding 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, options or warrants
to subscribe for Preferred Stock or securities convertible into Preferred Stock
at less than the current market price of the Preferred Stock, or (iii) upon the
distribution to holders of the Preferred Stock of evidences of indebtedness,
cash (excluding regular quarterly cash dividends), assets (other than dividends
payable in Preferred Stock) or subscription rights or warrants (other than
those referred to in (ii) immediately above).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least one percent (1%) of
the Purchase Price. No fractional shares of Preferred Stock are required to be
issued (other than fractions which are integral multiples of one one-hundredth
(1/100) of a share of Preferred Stock) and, in lieu thereof, the Company may
make an adjustment in cash based on the market price of the Preferred Stock on
the trading date immediately prior to the date of exercise.

     At any time after any person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of fifty percent (50%) or more
of the outstanding shares of Common Stock, the Board of Directors of the
Company may, without payment of the Purchase Price by the holder, exchange the
Rights (other than Rights owned by such person or group, which will become
void), in whole or in part, for shares of Common Stock at an exchange ratio of
one-half (1/2) the number of shares of Common Stock (or in certain
circumstances Preferred Stock) for which a Right is exercisable immediately
prior to the time of the Company's decision to exchange the Rights (subject to
adjustment).

     At any time until the Stock Acquisition Date, the Company may redeem the
Rights in whole, but not in part, at a price of $0.01 per Right (payable in
cash, shares of Common Stock or other consideration deemed appropriate by the
Board of Directors). Immediately upon the action of the Board of Directors
ordering redemption of the 



                                      -3-
<PAGE>   5

Rights, the Rights will terminate and the only right of the holders of Rights
will be to receive the $0.01 redemption price.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends. While the distribution of the Rights
will not be taxable to stockholders or to the Company, stockholders may,
depending upon the circumstances, recognize taxable income in the event that
the Rights become exercisable for Common Stock (or other consideration) of the
Company or for common stock of an acquiring company as set forth above or in
the event that the Rights are redeemed.

     Other than those provisions relating to the principal economic terms of
the Rights, any of the provisions of the Rights Agreement may be amended by the
Board of Directors of the Company at any time during the period in which the
Rights are redeemable. At any time when the Rights are no longer redeemable,
the provisions of the Rights Agreement may be amended by the Board only if such
amendment does not adversely affect the interest of holders of Rights
(excluding the interest of any Acquiring Person); provided, however, that no
amendment may cause the Rights again to become redeemable.

     A copy of the Rights Agreement specifying the terms of the Rights, the
Certificate of Designation, Preferences and Rights of Series A Junior
Participating Preferred Stock, form of Certificate of Amendment to Certificate
of Designation, Preferences and Rights of Series A Junior Participating
Preferred Stock and the form of Rights Certificate are filed herewith as
Exhibits and are incorporated herein by reference. Copies of the Rights
Agreement are also available free of charge from the Rights Agent. The
foregoing description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement.

                                RIGHTS AGREEMENT


         RIGHTS AGREEMENT, dated as of March 11, 1999, between TRINITY
INDUSTRIES, INC., a Delaware corporation (the "Company"), and The Bank of New
York (the "Rights Agent").

                                    RECITALS

         On March 11, 1999 (the "Rights Dividend Declaration Date"), the Board
of Directors of the Company authorized and declared a dividend distribution of
one Right for each share of Common Stock (as hereinafter defined) of the Company
outstanding at the close of business on April 27, 1999 (the "Record Date"), and
has authorized the issuance of one Right (as such number may be hereafter
adjusted as provided herein) for each share of Common Stock of the Company
issued between the Record Date (whether originally issued or delivered from the
Company's treasury) and the Distribution Date, each Right initially representing
the right to purchase one one-hundredth of a share of Series A Junior
Participating Preferred Stock of the Company having the rights, powers and
preferences set forth in the Certificate of Designation, Preferences and Rights,
as amended, attached hereto as Exhibit 1, upon the terms and subject to the
conditions hereinafter set forth (the "Rights");

                                    AGREEMENT

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

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

              (a)    "Acquiring Person" shall mean any Person who or which, 
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner (as such term is hereinafter defined) of 12% or more of the
shares of Common Stock then outstanding, but shall not include (i) the Company,
(ii) any Subsidiary of the Company, (iii) any employee benefit plan of the
Company or of any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such
plan, or (iv) any Person who becomes an Acquiring Person solely as a result of a
reduction in the number of shares of Common Stock outstanding due to the
repurchase of shares of Common Stock by the Company, unless and until such
Person shall purchase or otherwise become (as a result of actions taken by such
Person or its Affiliates or Associates) the Beneficial Owner of additional
shares of Common Stock constituting 1% or more of the then outstanding shares of
Common Stock. Notwithstanding the foregoing, if (i) the Board of Directors of
the Company determines in good faith that a Person who would otherwise be an
Acquiring Person, as



                                        1

<PAGE>   7



defined pursuant to the foregoing provisions of this paragraph, has become such
inadvertently (including, without limitation, because (A) such Person was
unaware that it beneficially owned a percentage of Common Stock that would
otherwise cause such Person to be an Acquiring Person, or (B) such Person was
aware of the extent of its Beneficial Ownership of Common Stock but had no
actual knowledge of the consequences of such Beneficial Ownership under this
Agreement) and without any intention of changing or influencing control of the
Company, and (ii) within ten Business Days of being requested by the Company to
advise it regarding the same, such Person certifies to the Company that such
Person acquired shares of Common Stock in excess of 11.99% inadvertently or
without knowledge of the terms of the Rights and who, together with all
Affiliates and Associates, thereafter does not acquire additional shares of
Common Stock and within ten Business Days of being requested by the Company to
do so disposes of the portion of such Common Stock in excess of 11.99%, then
such Person shall not be deemed to be or to have become an Acquiring Person for
any purposes of this Agreement; provided, however, that if the Person requested
to so certify fails to do so within ten Business Days of the Company's request
or such Person fails to dispose of such Common Stock in excess of 11.99% within
ten Business Days of the Company's request, then such Person shall become an
Acquiring Person immediately after such ten Business Day period.

              (b)    "Act" shall mean the Securities Act of 1933, as amended and
in effect from time to time.

              (c)    "Adjustment Shares" shall have the meaning set forth in

shall be deemed to "beneficially own," any securities:

                     (i)  which such Person or any of such Person's Affiliates 
or Associates, directly or indirectly, has the right to acquire (whether such
right is exercisable immediately or only after the passage of time) pursuant to
any agreement, arrangement or understanding (whether or not in writing) or upon
the exercise of conversion rights, exchange rights, rights, warrants or options,
or otherwise; provided, however, that a Person shall not, for purposes of this
paragraph (i), be deemed the



                                        2

<PAGE>   8



"Beneficial Owner" of or to "beneficially own," (A) securities tendered pursuant
to a tender or exchange offer made by such Person or any of such Person's
Affiliates or Associates until such tendered securities are accepted for
purchase or exchange, or (B) securities issuable upon exercise of Rights at any
time prior to the occurrence of a Triggering Event, or (C) securities issuable
upon exercise of Rights from and after the occurrence of a Triggering Event,
which Rights were acquired by such Person or any of such Person's Affiliates or
Associates prior to the Distribution Date or pursuant to Section 3(a) (Issuance
of Rights Certificates -- Distribution Date; Rights Certificates) or Section 22
(Issuance of New Rights Certificates) (the "Original Rights") or pursuant to

of Rights -- Adjustment of Number of Rights) in connection with an adjustment
made with respect to any Original Rights;

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

                     (iii) which are "beneficially owned," directly or 
indirectly, by any other Person (or any Affiliate or Associate thereof) 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 (ii) of this paragraph (f)) or
disposing of any voting securities of the Company;

provided, however, that nothing in this paragraph (f) shall cause a person
engaged in business as an underwriter of securities to be the "Beneficial Owner"
of or to "beneficially own," any securities acquired through such person's
participation in good faith in a firm commitment underwriting until the
expiration of forty (40) calendar days after the date of such acquisition.

              (g)    "Board" means the Board of Directors of the Company.

              (a)    Distribution Date; Rights Certificates. Until the earlier 
of (i) the Close of Business on the tenth Business Day after the Stock
Acquisition Date (or, if the tenth Business Day after the Stock Acquisition Date
occurs before the Record Date, the Close of Business on the Record Date), or
(ii) the Close of Business on the tenth Business Day (or such later date as the
Board shall determine prior to such time as any Person becomes an Acquiring
Person) 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 of the
Company or of any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such
plan) is first published or sent or given within the meaning of Rule 14d-2(a) of
the General Rules and Regulations under the Exchange Act, if upon consummation
thereof such Person would be the Beneficial Owner of 12% or more of the shares
of Common Stock then outstanding (the earlier of (i) and (ii) being herein
referred to as the "Distribution Date"), (x) the Rights will be evidenced
(subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock registered in the names of the holders of the
Common Stock (which certificates for Common Stock shall be deemed also to be
certificates for Rights) and not by separate certificates, and (y) the Rights
will be transferable only in connection with the transfer of the underlying
shares of Common Stock (including a transfer to the Company, except pursuant to
the provision of Section 23 (Redemption and Termination)). 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 the 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 substantially the form of Exhibit 2 hereto (the "Rights
Certificates"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in the
number of Rights per share of Common Stock has been made pursuant to Section
11(p) (Adjustment of Purchase Price; Number and Kind of Shares or Number of
Rights -- Common Stock Adjustments) at the time of distribution of the Rights
Certificates, the Company shall



                                        7

<PAGE>   13



make the necessary and appropriate rounding adjustments (in accordance with
Section 14(a) (Fractional Rights and Fractional Shares -- Fractional Rights)) 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)    Common Stock Certificates; Summary of Rights. With respect
to certificates for the Common Stock outstanding as of the Record Date, until
the Distribution Date, the Rights associated with the Common Stock represented
by such certificates will be evidenced by such certificates alone and the
registered holders of such Common Stock shall also be the registered holders of
the associated Rights. Until the earlier of the Distribution Date or the
Expiration Date, the transfer of any certificates representing shares of Common
Stock in respect of which Rights have been issued shall also constitute the
transfer of the Rights associated with such shares of Common Stock. On the
Record Date, or as soon as practicable thereafter, the Company will send a copy
of a Summary of Rights to Purchase Preferred Stock, in substantially the form of
Exhibit 3 hereto (the "Summary of Rights"), by first-class, postage-prepaid
mail, to each record holder of shares of Common Stock as of the close of
business of the Record Date, at the address of such holder shown on the records
of the Company.

              (c)    Legend. Rights shall be issued in respect of all 
certificates for shares of Common Stock which are issued (whether originally
issued or from the Company's treasury) after the Record Date but prior to the
earliest of the (i) Distribution Date, (ii) the Expiration Date, or (iii) the
Redemption Date, or, in certain circumstances provided in Section 22 (Issuance
of New Rights Certificates) after the Distribution Date. Certificates
representing such shares of Common Stock shall also be deemed to be certificates
for Rights, and shall bear the following legend:

              This certificate also evidences and entitles the holder hereof to
              certain Rights as set forth in the Rights Agreement dated as of
              March 11, 1999, by and between Trinity Industries, Inc. (the
              "Company") and The Bank of New York, as Rights Agent (the "Rights
              Agreement"), the terms of which are hereby incorporated herein by
              reference and a copy of which is on file at the principal offices
              of the Company. Under certain circumstances, as set forth in the
              Rights Agreement, such Rights will be evidenced by separate
              certificates and will no longer be evidenced by this certificate.
              The Company will mail to the holder of this certificate a copy of
              the Rights Agreement, as in effect on the date of mailing, without
              charge promptly after receipt of a written request therefor. Under
              certain circumstances set forth in the Rights Agreement, Rights
              issued to, or held by, any Person who is, was or becomes an
              Acquiring Person or any Affiliate or



                                        8

<PAGE>   14



              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.

With respect to such certificates containing the foregoing legend, until the
earliest of (i) the Distribution Date, (ii) the Expiration Date, and (iii) the
Redemption Date, (x) the Rights associated with the Common Stock represented by
such certificates shall be evidenced by such certificates alone, (y) the
registered holders of such Common Stock shall also be the registered holders of
the associated Rights, and (z) the transfer of any of such certificates shall
also constitute the transfer of the Rights associated with such shares of Common
Stock. In the event that the Company purchases, or acquires any shares of Common
Stock after the Record Date but prior to the Distribution Date, any rights
associated with such shares of Common Stock shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
shares of Common Stock which are no longer outstanding.

         Section 4.  Form of Rights Certificates.

              (a)    Form; Date. The Rights Certificates (and the forms of 
election to purchase and of assignment to be printed on the reverse thereof)
shall each be substantially in the form set forth in Exhibit 2 hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the Rights
may from time to time be listed or any securities association on whose
interdealer quotation system the Rights may be from time to time authorized for
quotation, or to conform to usage. Subject to the provisions of Section 11
(Adjustment of Purchase Price; Number and Kind of Shares or Number of Rights)
and Section 22 (Issuance of New Rights Certificates), 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 one one-hundredths
of a share of Preferred Stock as shall be set forth therein at the price set
forth therein (such exercise price per one one-hundredth of a share is referred
to herein as the "Purchase Price"), but the amount and type of securities
purchasable upon the exercise of each Right and the Purchase Price thereof shall
be subject to adjustment as provided herein.

              (b)    Acquiring Person Legend. Any Rights Certificate issued
pursuant to Section 3(a) (Issuance of Rights Certificates -- Distribution Date;
Rights Certificates) or Section 22 (Issuance of New Rights Certificates) 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) who becomes a transferee after the
Acquiring Person becomes such, or (iii) a transferee of an



                                        9

<PAGE>   15



Acquiring Person (or of any such Associate or Affiliate) who becomes a
transferee prior to or concurrently with the Acquiring Person becoming such and
receives such Rights pursuant to either (A) a transfer (whether or not for
consideration) from the Acquiring Person to holders of equity interests in such
Acquiring Person or to any Person with whom such Acquiring Person has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (B) a transfer which is part of a plan, arrangement or understanding
which has as a primary purpose or effect avoidance of Section 7(e) (Exercise of
Rights; Purchase Price; Expiration Date of Rights -- Termination of Acquiring
Person's Rights) and any Rights Certificate issued pursuant to Section 6
(Transfer, Split Up, Combination and Exchange of Rights Certificates; Mutilated,
Destroyed, Lost or Stolen Rights Certificates), Section 11 (Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights) or Section 22
(Issuance of New Rights Certificates) upon transfer, exchange, replacement or
adjustment of any other Rights Certificate referred to in this sentence, shall
contain (to the extent feasible) the following legend:

         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 Rights Agreement dated as of March 11, 1999, by and
         between Trinity Industries, Inc. and The Bank of New York, as Rights
         Agent). Accordingly, this Rights Certificate and the Rights represented
         hereby may become null and void in the circumstances specified in
         Section 7(e) (Exercise of Rights; Purchase Price; Expiration Date of
         Rights -- Termination of Acquiring Person's Rights) of such Agreement.

         Section 5.  Countersignature and Registration.

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

              (b)    Registration and Transfer. Following the Distribution Date,
the Rights Agent will keep or cause to be kept, at its principal office or
offices designated as the appropriate place for surrender of Rights Certificates
upon exercise or transfer, books for registration and transfer of the Rights
Certificates issued hereunder. Such books shall show the names and addresses of
the respective holders of the Rights Certificates, the number of Rights
evidenced on its face by each of the Rights Certificates and the date of each of
the Rights Certificates.

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

              (a)    Procedure. Subject to the provisions of Section 4(b) (Form
of Rights Certificates -- Acquiring Person Legend), Section 7(e) (Exercise of
Rights; Purchase Price; Expiration Date of Rights -- Termination of Acquiring
Person's Rights) and Section 14 (Fractional Rights and Fractional Shares), 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 one one-hundredths of a share of Preferred Stock (or, following
a Triggering Event, Common Stock, other securities, cash or other assets, as the
case may be) as the Rights Certificate or Certificates surrendered then entitled
such holder (or former holder in the case of a transfer) to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any Rights
Certificate or Certificates shall make such request in writing delivered to the
Rights Agent, and shall surrender the Rights Certificate or Certificates to be
transferred, split up, combined or exchanged at the principal office or offices
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 signed the certificate contained 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) or Affiliates or Associates thereof as the Company
shall reasonably request. Thereupon, the Rights Agent shall, subject to Section
4(b), Section 7(e) and Section 14, 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)    Issuance of New Rights Certificates. Upon receipt by the
Company and the Rights Agent of evidence reasonably satisfactory to them of the
loss, theft, destruction or mutilation of a Rights Certificate, and, in case of
loss, theft or destruction, of indemnity or security reasonably satisfactory to
them, and reimbursement to the Company and the Rights Agent of all reasonable
expenses incidental thereto, and upon



                                       11

<PAGE>   17



surrender to the Rights Agent and cancellation of the Rights Certificate if
mutilated, the Company will execute and deliver a new Rights Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

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

              (a)    Exercise. Subject to Section 7(e) (Exercise of Rights;
Purchase Price; Expiration Date of Rights -- Termination of Acquiring Person's
Rights), the registered holder of any Rights Certificate may exercise the Rights
evidenced thereby (except as otherwise provided herein, including, without
limitation, the restrictions on exercisability set forth in Section 9(c)
(Reservation and Availability of Capital Stock -- Registration under the Act),
Section 11(a)(iii) (Adjustment of Purchase Price; Number and Kind of Shares or
Number of Rights -- Certain Adjustments), Section 23(a) (Redemption and
Termination -- Redemption), and Section 24(b) (Exchange -- Effect of Exchange;
Procedure)) 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 principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price with respect to
the total number of one one-hundredths of a share of Preferred Stock (or other
securities, cash or other assets, as the case may be) as to which such
surrendered Rights are then exercisable and an amount equal to any applicable
transfer tax, at or prior to the earliest of (i) the Final Expiration Date, (ii)
the Redemption Date, or (iii) the expiration of the Rights pursuant to Section
13(d) (Consolidation, Merger or Sale or Transfer of Assets or Earning Power --
Exceptions) (the earliest of (i), (ii) and (iii) being herein referred to as the
"Expiration Date"). The payment of the Purchase Price and the applicable
transfer tax, if any (as such amount may be reduced pursuant to Section
11(a)(iii) (Adjustment of Purchase Price; Number and Kind of Shares or Number of
Rights -- Certain Adjustments)), may be made (x) in cash, (y) by certified
check, cashier's check or money order payable to the order of the Company, or
(z) by delivery of a certificate or certificates (with appropriate stock powers
executed in blank attached thereto) evidencing a number of shares of Common
Stock equal to the then Purchase Price divided by the closing price (as
determined pursuant to Section 11(d) (Adjustment of Purchase Price; Number and
Kind of Shares or Number of Rights -- Current Market Price)) per share of Common
Stock on the Trading Day immediately preceding the date of such exercise. In the
event that the Company is obligated to issue other securities (including Common
Stock) of the Company, pay cash and/or distribute other property pursuant to
Section 11(a) the Company will make all arrangements necessary so that such
other securities, cash and/or other property are available for distribution by
the Rights Agent, if and when appropriate. The Company reserves the right to
require prior to the occurrence of a Triggering Event that upon any exercise of
Rights, a number of Rights be exercised so that only whole shares of Preferred
Stock would be issued.




                                       12

<PAGE>   18



              (b)    Purchase Price. The Purchase Price for each one 
one-hundredth of a share of Preferred Stock pursuant to the exercise of a Right
shall initially be $200.00, and shall be subject to adjustment from time to time
as provided in Section 11 (Adjustment of Purchase Price; Number and Kind of
Shares or Number of Rights) and Section 13(a) (Consolidation, Merger or Sale or
Transfer of Assets or Earning Power -- Flip-over Event) and shall be payable in
accordance with paragraph (a) of this Section 7.

              (c)    Rights Agent Actions. Upon receipt of a Rights Certificate
representing exercisable Rights and the compliance by the holder of such Rights
Certificate with paragraph (a) of this Section 7, the Rights Agent shall,
subject to Section 20(k) (Duties of Rights Agent -- Exercise of Rights;
Consultation with Company), thereupon promptly (i) (A) requisition from any
transfer agent of the shares of Preferred Stock (or make available, if the
Rights Agent is the transfer agent for such shares) certificates for the total
number of one one-hundredths of a share of Preferred Stock to be purchased and
the Company hereby irrevocably authorizes its transfer agent to comply with all
such requests, or (B) if the Company shall have elected to deposit the total
number of shares of Preferred Stock issuable upon exercise of the Rights
hereunder with a depositary agent, requisition from the depositary agent
depositary receipts representing such number of one one-hundredths of a share of
Preferred Stock as are to be purchased (in which case certificates for the
shares of Preferred Stock represented by such receipts shall be deposited by the
transfer agent with the depositary agent) 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 (Fractional Rights and Fractional Shares), (iii)
after receipt thereof, deliver such certificates or depositary receipts 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.

              (d)    Partial Exercise. In case the registered holder of any 
Rights Certificate shall exercise less than all the Rights evidenced thereby, a
new Rights Certificate evidencing Rights equivalent to 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 (Fractional Rights and Fractional Shares).

              (e)    Termination of Acquiring Person's Rights. Notwithstanding
anything in this Agreement to the contrary, from and after the first occurrence
of a Flip-in 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) who becomes a
transferee after such Acquiring Person becomes such, or (iii) a transferee of an
Acquiring Person (or of any such Associate or Affiliate) who becomes a
transferee prior to or concurrently with the Acquiring Person becoming



                                       13

<PAGE>   19



such and receives such Rights pursuant to either (A) a transfer (whether or not
for consideration) from the Acquiring Person to holders of equity interests in
such Acquiring Person or to any Person with whom the Acquiring Person has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (B) a transfer which is part of a plan, arrangement or understanding
which has as a primary purpose or effect the avoidance of this Section 7(e),
shall become 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) (Form of Rights Certificates -- Acquiring Person Legend) are
complied with, but shall have no liability to any holder of Rights Certificates
or other Person as a result of its failure to make any determinations with
respect to an Acquiring Person or any of its respective Affiliates, Associates
or transferees hereunder.

              (f)    Surrender of Rights Certificates; Identity of Beneficial
Owner. Notwithstanding anything in this Agreement to the contrary, neither the
Rights Agent nor the Company shall be obligated to undertake any action with
respect to a registered holder upon the occurrence of any purported exercise as
set forth in this Section 7 unless such registered holder shall have (i)
completed and signed the certificate contained in the form of 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) 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 canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement, and the Rights Agent shall so cancel and
retire, any other Rights Certificate purchased or acquired by the Company
otherwise than upon the exercise thereof. The Rights Agent shall deliver all
canceled Rights Certificates to the Company, or shall, at the written request of
the Company, destroy such canceled 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)    Reservation of Capital Stock. The Company will use its best
efforts to reserve and keep available out of its authorized and unissued shares
of Preferred Stock (and, following the occurrence of a Triggering Event, out of
its authorized and unissued shares of Common Stock and/or other securities or
out of its authorized and issued shares of Common Stock held in its treasury),
the number of shares of Preferred



                                       14

<PAGE>   20



Stock (and, following the occurrence of a Triggering Event, Common Stock and/or
other securities) that, as provided in this Agreement, including the rights of
the Company under Section 11(a)(iii) (Adjustment of Purchase Price; Number and
Kind of Shares or Number of Rights -- Certain Adjustments) to otherwise fulfill
its obligations, will be sufficient to permit the exercise in full of all
outstanding Rights.

              (b)    Listing. So long as the shares of Preferred Stock (and,
following the occurrence of a Triggering Event, Common Stock and/or other
securities) issuable and deliverable upon the exercise of the Rights may be
listed on any national securities exchange or authorized for quotation on any
interdealer quotation system of any securities association, the Company shall
use its best efforts to cause, from and after such time as the Rights become
exercisable, all shares reserved for such issuance to be listed on such exchange
or quoted on such system upon official notice of issuance upon such exercise.

              (c)    Registration under the Act. The Company will use its best
efforts to (i) file, as soon as practicable following the earliest date after
the first occurrence of a Flip-in Event on which the consideration to be
delivered by the Company upon exercise of the Rights has been determined in
accordance with Section 11(a)(iii) (Adjustment of Purchase Price; Number and
Kind of Shares or Number of Rights -- Certain Adjustments), or as soon as is
required by law following the Distribution Date, as the case may be, a
registration statement on an appropriate form under the Act with respect to the
securities purchasable upon exercise of the Rights, (ii) cause such registration
statement to become effective as soon as practicable after such filing, and
(iii) cause such registration statement to remain effective (with a prospectus
at all times meeting the requirements of the Act) until the earlier of (A) the
date as of which the Rights are no longer exercisable for such securities, and
(B) the Expiration Date. The Company will also take such action as may be
appropriate under, or to ensure compliance with, the securities or "blue sky"
laws of the various states in connection with the exercisability of the Rights.
The Company may temporarily suspend, for a period of time not to exceed ninety
(90) calendar days after the date set forth in clause (i) of the first sentence
of this Section 9(c), the exercisability of the Rights in order to prepare and
file such registration statement and permit it to become effective. Upon any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect. In addition,
if the Company shall determine that a registration statement is required
following the Distribution Date, the Company may temporarily suspend the
exercisability of the Rights until such time as a registration statement has
been declared effective. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction if the
requisite qualification in such jurisdiction shall not have been obtained, the
exercise thereof shall not be permitted under applicable law or a registration
statement shall not have been declared effective.




                                       15

<PAGE>   21



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

              (e)    Transfer Taxes and Charges. The Company will pay when due 
and payable any and all federal and state transfer taxes and charges which may
be payable in respect of the issuance or delivery of the Rights Certificates and
of any certificates for a number of one one-hundredths of a share of Preferred
Stock (or Common Stock and/or other securities, as the case may be) upon the
exercise of Rights. The Company shall not, however, be required to pay any
transfer tax which may be payable in respect of any transfer or delivery of
Rights Certificates to a Person other than, or the issuance or delivery of a
number of one one-hundredths of a share of Preferred Stock (or Common Stock
and/or other securities, as the case may be) in respect of a name other than,
that of the registered holder of the Rights Certificates evidencing Rights
surrendered for exercise or to issue or deliver any certificates for a number of
one one-hundredths of a share of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until such tax 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 a number of one one-hundredths of a share of Preferred Stock (or
Common Stock and/or other securities, as the case may be) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of such fractional shares of Preferred Stock (or Common Stock and/or
other securities, as the case may be) represented thereby on, and such
certificate shall be dated as of, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares (fractional or otherwise) on, and such certificate shall be
dated, the next succeeding Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are open. Prior to the exercise of the Rights evidenced thereby, the holder of a
Rights Certificate shall not be entitled to any rights of a stockholder of the
Company with respect to shares for which the Rights shall be exercisable,
including, without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

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

              (a)    Certain Adjustments.

                     (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 or split 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) and Section 7(e)
         (Exercise of Rights; Purchase Price; Expiration Date of Rights --
         Termination of Acquiring Person's Rights), the Purchase Price in effect
         at the time of the record date for such dividend or of the effective
         date of such subdivision, split, combination or reclassification, and
         the number and kind of shares of Preferred Stock or capital stock, as
         the case may be, issuable on such date, shall be proportionately
         adjusted so that the holder of any Right exercised after such time
         shall be entitled to receive, upon payment of the aggregate adjusted
         Purchase Price then in effect necessary to exercise a Right in full,
         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 and at a time when the Preferred Stock
         (or other capital stock, as the case may be) transfer books of the
         Company were open, such holder would have owned upon such exercise and
         been entitled to receive by virtue of such dividend, subdivision,
         split, combination or reclassification. If an event occurs which would
         require an adjustment under both this Section 11(a)(i) and Section
         11(a)(ii) 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).

                     (ii)  In the event:

                           (A) (1) any Acquiring Person or any Associate or
                  Affiliate of any Acquiring Person, at any time after the date
                  of this Agreement, directly or indirectly, 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 the Common Stock of the Company
                  shall remain outstanding and unchanged, or (2) subject to
                  Section 23 (Redemption and Termination), any Person (other
                  than the Company, any Subsidiary of the Company, any employee
                  benefit plan of the Company or of any Subsidiary of the
                  Company, or any Person or entity

                  organized, appointed or established by the Company for or
                  pursuant to the terms of any such plan), alone or together
                  with its Affiliates and Associates, shall, at any time after
                  the Rights Dividend Declaration Date, become an Acquiring
                  Person, unless the event causing such Person to become an
                  Acquiring Person is a Flip-over Event, or is an acquisition of
                  shares of Common Stock pursuant to a tender offer or an
                  exchange offer for all outstanding shares of Common Stock at a
                  price and on terms determined by the Board of Directors, prior
                  to the public announcement of such tender offer or exchange
                  offer, after receiving advice from one or more investment
                  banking firms selected by the Board of Directors, to be (a) at
                  a price which is fair to the stockholders of the Company
                  (taking into account all factors which the Board of Directors
                  deem relevant including, without limitation, prices which
                  could reasonably be achieved if the Company or its assets were
                  sold on an orderly basis designed to realize maximum value)
                  and (b) otherwise in the best interests of the Company and its
                  stockholders, other than such Acquiring Person, its Affiliates
                  and its Associates; or

                           (B) 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) (Consolidation, Merger or Sale or
                  Transfer of Assets or Earning Power -- Flip-over Event) 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, promptly following the occurrence of any such Flip-in Event
         (whether described in Section 11(a)(ii)(A) or (B)), proper provision
         shall be made so that each holder of a Right (except as provided below
         and in Section 7(e) (Exercise of Rights; Purchase Price; Expiration
         Date of Rights -- Termination of Acquiring Person's Rights)) 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 one one-hundredths of a share of Preferred
         Stock, such number of shares of Common Stock of the Company as shall
         equal the result obtained by (x) multiplying the then current Purchase
         Price by the then number of one one-hundredths of a share of Preferred
         Stock for which a Right was exercisable immediately prior to the first
         occurrence of a Flip-in Event, and (y) dividing that product (which,
         following such first occurrence, shall thereafter



                                       18

         be referred to as the "Purchase Price" for each Right and for all
         purposes of this Agreement) by 50% of the Current Market Price per
         share of Common Stock on the date of such first occurrence (such number
         of shares being referred to as the "Adjustment Shares").

                     (iii) In the event that the number of shares of
         Common Stock that are authorized by the Company's Certificate of
         Incorporation but not outstanding or 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 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, the "Spread"), and (B) with respect to
         each Right, subject to Section 7(e)(Exercise of Rights; Purchase Price;
         Expiration Date of Rights -- Termination of Acquiring Person's Rights),
         make adequate provision to substitute for the Adjustment Shares, upon
         payment of the applicable Purchase Price, (1) cash, (2) a reduction in
         the Purchase Price, (3) Common Stock or other equity securities of the
         Company (including, without limitation, shares, or units of shares, of
         preferred stock which the Board has deemed to have essentially the same
         value or economic rights as shares of Common Stock (such shares of
         preferred stock being referred to as "Common Stock Equivalents")), (4)
         debt securities of the Company, (5) other assets, or (6) any
         combination of the foregoing, having an aggregate value equal to the
         Current Value (less the amount of any reduction in the Purchase Price),
         where such aggregate value has been determined by the Board based upon
         the advice of a nationally recognized investment banking firm selected
         by the Board; provided, however, that if the Company shall not have
         made adequate provision to deliver value pursuant to clause (B) above
         within thirty (30) calendar days following the first occurrence of a
         Flip-in Event (the date of such Flip-in Event being referred to herein
         as the "Flip-in Trigger Date"), then the Company shall be obligated to
         deliver, upon the surrender for exercise of a Right and without
         requiring payment of the Purchase Price, shares of Common Stock (to the
         extent available) and then, if necessary, cash, which shares and/or
         cash have an aggregate value equal to the Spread. If the Board shall
         determine in good faith that it is likely that sufficient additional
         shares of Common Stock or other equity securities could be authorized
         for issuance upon exercise in full of the Rights, the thirty (30)
         calendar day period set forth above may be extended to the extent
         necessary, but not more than ninety (90) calendar days after the
         Flip-in Trigger Date, in order that the Company may seek stockholder
         approval for the authorization of such additional shares (such period,
         the "Substitution Period"). To the extent that the Company determines
         that some action need be taken pursuant to the first and/or second
         sentences of this Section 11(a)(iii), the Company (x) shall provide,
         subject to Section 7(e), that such action shall apply uniformly to all
         outstanding Rights, and (y) may suspend the exercisability of the
         Rights until the expiration of the Substitution Period in



                                       19

<PAGE>   25



         order to seek any authorization of additional shares and/or to decide
         the appropriate form of distribution to be made pursuant to such first
         sentence and to determine the value thereof. In the event of any such
         suspension, the Company shall issue a public announcement stating that
         the exercisability of the Rights has been temporarily suspended, as
         well as a public announcement at such time as the suspension is no
         longer in effect. For purposes of this Section 11(a)(iii), the value of
         the Common Stock shall be the Current Market Price per share of the
         Common Stock on the Flip-in Trigger Date and the value of any Common
         Stock Equivalent shall be deemed to have the same value as the Common
         Stock on such date.

                     (iv)  If the rules of the national securities exchange, 
         registered as such pursuant to Section 6 of the Exchange Act, or of the
         national securities association, registered as such pursuant to Section
         15A of the Exchange Act, on which the Common Stock is principally
         traded or quoted would prohibit such exchange or association from
         listing or continuing to list, or from authorizing for or continuing
         quotation and/or transaction reporting through an inter-dealer
         quotation system, the Common Stock or other equity securities of the
         Company if the Rights were to be exercised for shares of Common Stock
         in accordance with subparagraph (ii) of this Section 11(a) because such
         issuance would nullify, restrict or disparately reduce the per share
         voting rights of holders of Common Stock, the Company shall: (A)
         determine the Spread, and (B) with respect to each Right, make adequate
         provision to substitute for the Adjustment Shares, upon payment of the
         applicable Purchase Price, (1) cash, (2) a reduction in the Purchase
         Price, (3) equity securities of the Company, including, without
         limitation, Common Stock Equivalents, other than securities which would
         have the effect of nullifying, restricting or disparately reducing the
         per share voting rights of holders of Common Stock, (4) debt securities
         of the Company, (5) other assets, or (6) any combination of the
         foregoing, having an aggregate value equal to the Current Value, where
         such aggregate value has been determined by the Board based upon the
         advice of a recognized investment banking firm selected by the Board;
         provided, however, if the Company shall not have made adequate
         provision to deliver value pursuant to clause (B) above within thirty
         (30) calendar days following the Flip-in 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, cash having
         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)(iv), the Company (x) shall provide,
         subject to Section 7(e) (Exercise of Rights; Purchase Price; Expiration
         Date of Rights -- Termination of Acquiring Person's Rights), that such
         action shall apply uniformly to all outstanding Rights and (y) may
         suspend the exercisability of the Rights, but not longer than ninety
         (90) calendar days after the Flip-in Trigger Date, in order to decide
         the appropriate form of distribution to be made pursuant to such first
         sentence and to determine the value thereof. In the event of any such
         suspension, the Company shall issue a public announcement stating that
         the exercisability of



                                       20

<PAGE>   26



         the Rights has been temporarily suspended, as well as a public
         announcement at such time as the suspension is no longer in effect. For
         purposes of this Section 11(a)(iv), the value of the Common Stock shall
         be the Current Market Price per share of the Common Stock on the
         Flip-in Trigger Date and the value of any Common Stock Equivalent shall
         be deemed to have the same value as the Common Stock on such date.

              (b)    Purchase Price Adjustment -- Capital Stock. 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 (45) calendar days after such record
date) Preferred Stock (or shares having the same rights, privileges and
preferences as the 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 per share 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 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 Board, whose determination shall be described in a statement filed with
the Rights Agent and shall be binding on the Rights Agent and the holders of the
Rights. Shares of Preferred Stock owned by or held for the account of the
Company shall not be deemed outstanding for the purpose of any such computation.
Such adjustment shall be made successively whenever such a record date is fixed,
and in the event that such rights 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)    Purchase Price Adjustment -- Cash, Assets, etc. In case the
Company shall fix a record date for a distribution to all holders 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 Preferred Stock, but including



                                       21

<PAGE>   27



any dividend payable in stock other than Preferred Stock) or subscription rights
or warrants (excluding those referred to in Section 11(b) (Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights Purchase Price
Adjustment -- Capital Stock)), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the Current Market Price per share of Preferred Stock on such record
date, less the fair market value (as determined in good faith by the Board,
whose determination shall be described in a statement filed with the Rights
Agent) of the portion of the cash, assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to a share of
Preferred Stock and the denominator of which shall be such Current Market Price
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)    Current Market Price.

                     (i)   For the purpose of any computation hereunder, other 
than computations made pursuant to Section 11(a)(iii) (Adjustment of Purchase
Price; Number and Kind of Shares or Number of Rights -- Certain Adjustments) the
Current Market Price per share of Common Stock on any date shall be deemed to be
the average of the daily closing prices per share of such Common Stock for the
thirty (30) consecutive Trading Days immediately prior to such date, and for
purposes of computations made pursuant to Section 11(a)(iii) the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily closing prices per share of such Common Stock for the ten (10)
consecutive Trading Days immediately following such date; provided, however,
that in the event that the Current Market Price per share of the Common Stock is
determined during a period following the announcement by the issuer of such
Common Stock of (A) a dividend or distribution on such Common Stock payable in
shares of such Common Stock or securities convertible into shares of such Common
Stock (other than the Rights), or (B) any subdivision, combination or
reclassification of such Common Stock and the ex-dividend date for such dividend
or distribution, or the record date for such subdivision, combination or
reclassification shall not have occurred prior to the commencement of the
requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth
above, then, and in each such case, the Current Market Price shall be properly
adjusted to take into account ex-dividend trading. The closing price for each
Trading Day shall be the last sale price, regular way, or, in case no such sale
takes place on such Trading Day, the average of the closing bid and asked
prices, regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the shares of Common Stock are not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which



                                       22

<PAGE>   28



the shares of Common Stock are listed or admitted to trading or, if the shares
of Common Stock are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by the
National Association of Securities Dealers, Inc. Automated Quotation System or
such other system then in use, or, if on any such date the shares of Common
Stock are not quoted by any such organization, the average of the closing bid
and asked prices as furnished by a professional market maker making a market in
the Common Stock selected by the Board. If on any such date no market maker is
making a market in the Common Stock, the fair value of such shares on such date
as determined in good faith by the Board shall be used. The term "Trading Day"
shall mean a day on which the principal national securities exchange on which
the shares of Common Stock are listed or admitted to trading is open for the
transaction of business or, if the shares of Common Stock are not listed or
admitted to trading on any national securities exchange, a Business Day. If the
Common Stock is not publicly held or not so listed or traded, Current Market
Price per share shall mean the fair value per share as determined in good faith
by the Board, whose determination shall be described in a statement filed with
the Rights Agent and shall be conclusive for all purposes.

                     (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 the Common Stock in clause (i) of this
Section 11(d) (other than the last 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 number may be appropriately adjusted for such events as stock
splits, stock dividends and recapitalizations with respect to the Common Stock
occurring after the date of this Agreement) multiplied by the Current Market
Price per share of the Common Stock. If neither the Common Stock nor the
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 Board, whose determination shall be described in
a statement filed with the Rights Agent and shall be conclusive for all
purposes. For all purposes of this Agreement, the Current Market Price of one
one-hundredth of a share of Preferred Stock shall be equal to the Current Market
Price of one share of Preferred Stock divided by 100.

              (e)    Purchase Price Adjustment Threshold. Anything herein to the
contrary notwithstanding, no adjustment in the Purchase Price shall be required
unless such adjustment would require an increase or decrease of at least one
percent (1%) in the Purchase Price; provided however, that any adjustments which
by reason of this Section 11(e) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Section 11 (Adjustment of Purchase Price; Number and Kind of Shares
or Number of Rights) shall be made to the nearest cent or to the nearest
hundredth of a share of Common Stock or



                                       23

<PAGE>   29



other share or one-hundred-thousandth 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
(3) years from the date of the transaction which mandates such adjustment, or
(ii) the Expiration Date.

              (f)    Equivalent Adjustments. If as a result of an adjustment 
made pursuant to Section 11(a)(ii) (Adjustment of Purchase Price; Number and
Kind of Shares or Number of Rights -- Certain Adjustments) or Section 13(a)
(Consolidation Merger or Sale or Transfer of Assets or Earning Power --
Flip-over Event) 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), (e), (g), (h), (i), (j), (k) and (m), and the provisions of Sections 7, 9,
10, 13 and 14 with respect to the Preferred Stock shall apply on like terms to
any such other shares.

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

              (h)    Preferred Stock Anti-Dilution. Unless the Company shall 
have exercised its election as provided in Section 11(i) (Adjustment of Purchase
Price; Number and Kind of Shares or Number of Rights -- Adjustment of Number of
Rights), upon each adjustment of the Purchase Price as a result of the
calculations made in Section 11(b) (Adjustment of Purchase Price; Number and
Kind of Shares or Number of Rights -- Purchase Price Adjustment -- Capital
Stock) and Section 11(c) (Adjustment of Purchase Price; Number and Kind of
Shares or Number of Rights -- Purchase Price Adjustment -- Cash, Assets, etc.),
each Right outstanding immediately prior to the making of such adjustment shall
thereafter evidence the right to purchase, at the adjusted Purchase Price, that
number of one one-hundredths of a share of Preferred Stock (calculated to the
nearest one-hundred-thousandth) obtained by (i) multiplying (x) the number of
one one-hundredths of a share covered by a Right immediately prior to this
adjustment, by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price, and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

              (i)    Adjustment of Number of Rights. 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 one one-hundredths of a share
of Preferred Stock purchasable upon the exercise of a Right. Each of the Rights
outstanding after the adjustment in the number of Rights shall be exercisable
for the number of one 



                                       24

<PAGE>   30



one-hundredths of a share 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 one-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights, indicating the record date for the adjustment, and, if known at the
time, the amount of the adjustment to be made. 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 (10) calendar days
later than the date of the public announcement. If Rights Certificates have been
issued, upon each adjustment of the number of Rights pursuant to this Section
11(i), the Company shall, as promptly as practicable, cause to be distributed to
holders of record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 (Fractional Rights and Fractional Shares) the
additional Rights to which such holders shall be entitled as a result of such
adjustment, or, at the option of the Company, shall cause to be distributed to
such holders of record in substitution and replacement for the Rights
Certificates held by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Rights Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Rights Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company, the adjusted Purchase Price) and shall be registered in the
names of the holders of record of Rights Certificates on the record date
specified in the public announcement.

              (j)    Rights Certificates. Irrespective of any adjustment or 
change in the Purchase Price or the number of one one-hundredths of a share 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 one one-hundredth of a share and the number of one
one-hundredths of a share which were expressed in the initial Rights
Certificates issued hereunder.

              (k)    Adjustment Below Par Value. Before taking any action that
would cause an adjustment reducing the Purchase Price below the then par or
stated value, if any, of the number of one one-hundredths of a share of
Preferred Stock issuable upon exercise of the Rights, the Company shall take any
corporate action which is or may, in the opinion of its counsel, be necessary in
order that the Company may validly and legally issue fully paid and
nonassessable such number of one one-hundredths of a share of Preferred Stock at
such adjusted Purchase Price.

              (l)    Adjustment Effective as of Future Date; Exercise. In any 
case in which this Section 11 (Adjustment of Purchase Price; Number and Kind of
Shares or Number of Rights) 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


                                       25

<PAGE>   31

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

              (m)    Tax Adjustments. Anything in this Section 11 (Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights) 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 its good faith judgment the Board 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 stockholders.

              (n)    Restriction on Certain Transactions. The Company shall not,
at any time after the earlier of the Stock Acquisition Date or 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) (Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights -- Restriction
Against Diminishing Benefits of the Rights)), (ii) merge with or into any other
Person (other than a Subsidiary of the Company in a transaction which complies
with Section 11(o)), (iii) enter into a statutory share exchange or similar
transaction with any other Person (other than a Subsidiary of the Company in a
transaction which complies with Section 11(o)), or (iv) sell or transfer (or
permit any Subsidiary to sell or transfer), in one transaction, or a series of
related transactions, assets, cash flow or earning power aggregating more than
50% of the assets, cash flow 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)), if (x) at the time of or immediately after such
consolidation, merger, statutory share exchange or similar transaction, 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, statutory
share exchange or similar transaction, or sale, the stockholders of the Person
who constitutes, or would constitute, the "Principal Party" for purposes of
Section 13(a)



                                       26

(Consolidation, Merger or Sale or Transfer of Assets or Earning Power --
Flip-over Event) shall have received a distribution of Rights previously owned
by such Person or any of its Affiliates and Associates.

              (o)    Restriction Against Diminishing Benefits of the Rights. The
Company covenants and agrees that, after the earlier of the Stock Acquisition
Date or the Distribution Date, it will not, except as permitted by Section 23
(Redemption and Termination) or Section 27 (Supplements and Amendments) 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.

              (p)    Common Stock Adjustments. 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 Common Stock payable in shares
of Common Stock, (ii) subdivide or split the outstanding shares of Common Stock,
or (iii) combine the outstanding shares of Common Stock into a smaller number of
shares, the number of Rights associated with each share of 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 Common Stock following any such event shall equal
the result obtained by multiplying the number of Rights associated with each
share of Common Stock immediately prior to such event by a fraction, the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to the occurrence of the event and the denominator
of which shall be the total number of shares of Common Stock outstanding
immediately following the occurrence of such event. The adjustments provided for
in this Section 11(p) shall be made successively whenever such a dividend is
declared or paid or such subdivision, combination or consolidation is effected.

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 (Adjustment of Purchase
Price; Number and Kind of Shares or Number of Rights) and Section 13
(Consolidation, Merger or Sale or Transfer of Assets or Earning Power) 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 Common Stock, a copy of such certificate, and (c) mail or cause the
Rights Agent to mail a brief summary thereof to each holder of a Rights
Certificate (or, if prior to the Distribution Date, to each holder of a
certificate representing shares of Common Stock) in accordance with Section 26
(Notices). The Rights Agent shall be fully protected in relying on any such
certificate and on any adjustment therein contained.

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

              (a)    Flip-over Event. In the event that, following the Stock
Acquisition Date, directly or indirectly, (x) the Company shall consolidate
with, or merge with and into, or enter into a statutory stock exchange or
similar transaction with, any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o)(Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights -- Restriction
Against Diminishing Benefits of the Rights)), and the Company shall not be the
continuing or surviving corporation of such consolidation, merger or statutory
share exchange or similar transaction, (y) any Person (other than a Subsidiary
of the Company in a transaction which complies with Section 11(o)) shall
consolidate with, or merge with or into, or enter into a statutory stock
exchange or similar transaction with, the Company, and the Company shall be the
continuing or surviving corporation of such consolidation, merger or statutory
share exchange or similar transaction and, in connection with such
consolidation, merger or statutory share exchange or similar transaction, all or
part of the outstanding shares of Common Stock shall be changed 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), in one transaction or a
series of related transactions, assets, cash flow or earning power aggregating
more than 50% of the assets, cash flow or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more transactions each of which
complies with Section 11(o)), then, and in each such case (except as may be
contemplated by Section 13(d) (Consolidation, Merger or Sale or Transfer of
Assets or Earning Power -- Exceptions)), (i) proper provision shall be made so
that: each holder of a Right, except as provided in Section 7(e) (Exercise of
Rights; Purchase Price; Expiration Date of Rights -- Termination of Acquiring
Person's Rights) shall thereafter have the right to receive, upon the exercise
thereof at the then current Purchase Price in accordance with the terms of this
Agreement, such number of validly authorized and issued, fully paid,
nonassessable and freely tradeable shares of Common Stock of the Principal
Party, not subject to any liens, encumbrances, rights of first refusal or other
adverse claims, as shall be equal to the result obtained by (A) multiplying the
then current Purchase Price by the number of one one-hundredths of a share of
Preferred Stock for which a Right is exercisable immediately prior to the first
occurrence of a Flip-over Event (or, if a Flip-in Event has occurred prior to
the first occurrence of a Flip-over Event, multiplying the number of such one
one-hundredths of a share for which a Right was exercisable immediately prior to
the first occurrence of a Flip-in Event by the Purchase Price in effect
immediately prior to such first occurrence), and (B) dividing that product
(which, following the first occurrence of a Flip-over Event, shall be referred
to as the "Purchase Price" for each Right and for all purposes of this
Agreement) by 50% of the Current Market Price per share of the Common Stock of
such Principal Party on the date of consummation of such Flip-over Event; (ii)
such Principal Party shall thereafter be liable for, and shall assume,



                                       28

<PAGE>   34



by virtue of such Flip-over Event, all the obligations and duties of the Company
pursuant to this Agreement; (iii) the term "Company" shall thereafter be deemed
to refer to such Principal Party, it being specifically intended that the
provisions of Section 11 (Adjustment of Purchase Price; Number and Kind of
Shares or Number of Rights) shall apply only to such Principal Party following
the first occurrence of a Flip-over Event; (iv) such Principal Party shall take
such steps (including, but not limited to, the reservation of a sufficient
number of shares of its Common Stock) in connection with the consummation of any
such transaction as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to its
shares of Common Stock thereafter deliverable upon the exercise of the Rights;
and (v) the provisions of Section 11(a)(ii) (Adjustment of Purchase Price;
Number and Kind of Shares or Number of Rights -- Certain Adjustments) hereof
shall be of no effect following the first occurrence of any Flip-over Event.
Notwithstanding anything in this Agreement to the contrary, if a Flip-over Event
shall occur prior to the Distribution Date, then (i) the Rights shall survive
such Flip-over Event and shall not as a result thereof be cancelled, terminated
or otherwise cease to exist and (ii) the Distribution Date shall be deemed to
have occurred on the day immediately prior to the date of such Flip-over Event.

              (b)    Principal Party. "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) (Consolidation,
         Merger or Sale or Transfer of Assets or Earning Power -- Flip-over
         Event), the Person that is the issuer of any securities into which
         shares of Common Stock of the Company are converted in such
         consolidation, merger or statutory share exchange or similar
         transaction, and if no securities are so issued, the Person that is the
         other party to such consolidation, merger or statutory share exchange
         or similar transaction, and

                     (ii)   in the case of any transaction described in clause 
         (z) of the first sentence of Section 13(a) (Consolidation, Merger or
         Sale or Transfer of Assets or Earning Power -- Flip-over Event), the
         Person that is the party receiving the greatest portion of the assets,
         cash flow or earning power transferred pursuant to such transaction or
         transactions;

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding twelve (12)
month period registered under Section 12 of the Exchange Act, and such Person is
a direct or indirect Subsidiary of another Person the Common Stock of which is
and has been so registered, "Principal Party" shall refer to such other Person;
and (2) in case such Person is a Subsidiary, directly or indirectly, of more
than one Person, the Common Stocks of two or more of which are and have been so
registered, "Principal Party" shall refer to whichever of such Persons is the
issuer of the total outstanding Common Stock having the greatest aggregate
market value.



                                       29

<PAGE>   35



              (c)    Supplemental Agreement. The Company shall not consummate a
Flip-over Event 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 (Consolidation, Merger or Sale or Transfer of Assets or Earning
Power) and unless prior thereto the Company and such Principal Party shall have
executed and delivered to the Rights Agent a supplemental agreement providing
for the terms set forth in paragraphs (a) and (b) of this Section 13 and further
providing that, as soon as practicable after the date of such Flip-over Event,
the Principal Party will

                     (i)    prepare and file a registration statement under the
         Act, with respect to the Rights and the securities purchasable upon
         exercise of the Rights on an appropriate form, and will use its best
         efforts to cause such registration statement to (A) become effective as
         soon as practicable after such filing and (B) remain effective (with a
         prospectus at all times meeting the requirements of the Act) until the
         Expiration Date and take all such other action as may be necessary to
         enable the Principal Party to issue the securities purchasable upon
         exercise of the Rights, including but not limited to the registration
         or qualification of such securities under all requisite securities laws
         or jurisdictions of the various states and the listing of such
         securities on such exchange and trading markets as may be necessary or
         appropriate; and

                     (ii)   will 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.

The provisions of this Section 13 (Consolidation, Merger or Sale or Transfer of
Assets or Earning Power) shall similarly apply to successive consolidations,
mergers or statutory share exchanges or similar transactions or sales or other
transfers. In the event that a Flip-over Event shall occur at any time after the
occurrence of a Flip-in Event, the Rights which have not theretofore been
exercised shall thereafter become exercisable in the manner described in Section
13(a) (Consolidation, Merger or Sale or Transfer of Assets or Earning Power --
Flip-over Event).

              (d)    Exceptions. Notwithstanding anything in this Agreement to 
the contrary, Section 13 (Consolidation, Merger or Sale or Transfer of Assets or
Earning Power) shall not be applicable to a transaction described in
subparagraphs (x) and (y) of Section 13(a) (Consolidation, Merger or Sale or
Transfer of Assets or Earning Power -- Flip-over Event) if (i) such transaction
is consummated with a Person or Persons who acquired shares of Common Stock
pursuant to a tender offer or exchange offer for all outstanding shares of
Common Stock which complies with the provisions of Section 11(a)(ii)(A)
(Adjustment of Purchase Price; Number and Kind of Shares or Number of Rights --
Certain Adjustments) (or a wholly-owned subsidiary of any such



                                       30

<PAGE>   36



Person or Persons), (ii) the price per share of Common Stock offered in such
transaction is not less than the price per share of Common Stock paid to all
holders of shares of Common Stock whose shares were purchased pursuant to such
tender or exchange offer and (iii) the form of consideration being offered in
such transaction is the same as the form of consideration paid to all holders of
shares of Common Stock whose shares were purchased pursuant to such tender offer
or exchange offer. Upon consummation of any such transaction contemplated by
this Section 13(d), all Rights hereunder shall expire.

         Section 14. Fractional Rights and Fractional Shares.

              (a)    Fractional Rights. The Company shall not be required to 
issue fractions of Rights, except prior to the Distribution Date as provided in
Section 11(p) (Adjustment of Purchase Price; Number and Kind of Shares or Number
of Rights -- Common Stock Adjustments), or to distribute Rights Certificates
which evidence fractional Rights. In lieu of such fractional Rights, there shall
be paid to the registered holders of the Rights Certificates with regard to
which such fractional Rights would otherwise be issuable, an amount in cash
equal to the same fraction of the current market value of a whole Right. For
purposes of this Section 14(a), the current market value of a whole Right shall
be the closing price of the Rights for the Trading Day immediately prior to the
date on which such fractional Rights would have been otherwise issuable. The
closing price of the Rights for any Trading Day shall be the last sale price,
regular way, or, in case no such sale takes place on such Trading Day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Rights are not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Rights are listed or admitted to trading, or if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market as reported by the National Association of
Securities Dealers, Inc. Automated Quotation System or such other system then in
use or, if on any such date the Rights are not quoted by any such organization,
the average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Rights selected by the Board. If on any such
date no such market maker is making a market in the Rights, the fair value of
the Rights on such date as determined in good faith by the Board shall be used.

              (b)    Fractional Shares of Preferred Stock. 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 which may at the option of the Company, be evidenced by
depositary receipts) upon exercise of the Rights or to distribute certificates
which evidence fractional shares of Preferred Stock (other than fractions which
are integral multiples of one one-hundredth of a share of Preferred



                                       31

<PAGE>   37



Stock). Interests in fractions of Preferred Stock in integral multiples of one
one-hundredth of a share of Preferred Stock may, at the election of the Company,
be evidenced by depositary receipts, pursuant to an appropriate agreement
between the Company and a depositary selected by it; provided, however, that
such agreement shall provide that the holders of such depositary receipts shall
have all the rights, privileges and preferences to which they are entitled as
beneficial owners of the Preferred Stock represented by such depositary
receipts. In lieu of fractional shares of Preferred Stock that are not integral
multiples of one one-hundredth of a share of Preferred Stock, 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
current market value of one one-hundredth of a share of Preferred Stock. For
purposes of this Section 14(b), the current market value of one one-hundredth of
a share of Preferred Stock shall be one one-hundredth of the closing price of a
share of Preferred Stock (as determined pursuant to Section 11(d)(ii)
(Adjustment of Purchase Price; Number and Kind of Shares or Number of Rights --
Current Market Price) for the Trading Day immediately prior to the date of such
exercise.

              (c)    Fractional Shares of Common Stock Following the occurrence
of a Triggering Event, the Company shall not be required to issue fractions of
shares of Common Stock upon exercise of the Rights or to distribute certificates
which evidence fractional shares of Common Stock. In lieu of fractional shares
of Common Stock, the Company may pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of one (1) share
of Common Stock. For purposes of this Section 14(c), the current market value of
one share of Common Stock shall be the closing price of one share of Common
Stock (as determined pursuant to Section 11(d)(i) (Adjustment of Purchase Price;
Number and Kind of Shares or Number of Rights -- Current Market Price) for the
Trading Day immediately prior to the date of such exercise.

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

         Section 15. Rights of Action. All rights of action in respect of this
Agreement are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock); and any registered holder of any Rights Certificate (or, prior to
the Distribution Date, of the Common Stock), without the consent of the Rights
Agent or of the holder of any other Rights Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in his or her own behalf and for
his or her own benefit, enforce, and may institute and maintain any suit, action
or proceeding against the Company to enforce, or otherwise act in respect of,
his or her right to exercise the Rights evidenced by such Rights Certificate in
the manner



                                       32

<PAGE>   38



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 Common Stock;

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

              (c)    subject to Section 6(a) (Transfer, Split Up, Combination 
and Exchange of Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights
Certificates -- Procedure) and Section 7(f) (Exercise of Rights; Purchase Price;
Expiration Date of Rights -- Surrender of Rights Certificates; Identity of
Beneficial Owner), the Company and the Rights Agent may deem and treat the
person in whose name a Rights Certificate (or, prior to the Distribution Date,
the associated Common Stock certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Rights Certificates or the associated Common Stock
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent, subject to
the last sentence of Section 7(e) (Exercise of Rights; Purchase Price;
Expiration Date of Rights -- Termination of Acquiring Person's Rights), shall be
required to be affected by any notice to the contrary; and

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

         Section 17. Rights Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of one
one-hundredths of a share 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 stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in Section 25 (Notice of Certain Events)), 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)    Compensation. The Company shall pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from time
to time, on demand of the Rights Agent, its reasonable expenses and counsel fees
and other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
agrees to indemnify the Rights Agent for, and to hold it harmless against, any
loss, liability or expense, incurred without negligence, bad faith or willful
misconduct on the part of the Rights Agent, for anything done or omitted to be
done by the Rights Agent in connection with the acceptance and administration of
this Agreement, including the costs and expenses of defending against or
investigating any claim of liability in the premises.

              (b)    Reliance. The Rights Agent shall be protected and shall 
incur no liability for or in respect of any action taken, suffered or omitted to
be taken by it in connection with its administration of this Agreement in
reliance upon any Rights Certificate or certificate for Common Stock or for
other securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons, or otherwise upon the advice of counsel as set
forth in Section 20 (Duties of Rights Agent).

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

              (a)    Successor. Any corporation into which the Rights Agent or 
any successor Rights Agent may be merged or with which it may be consolidated,
or any corporation resulting from any merger or consolidation to which the
Rights Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the corporate trust or stock transfer business of the Rights Agent
or any successor Rights Agent, shall



                                       34

<PAGE>   40



be the successor to the Rights Agent under this Agreement without the execution
or filing of any paper or any further act on the part of any of the parties
hereto; provided, however, that such corporation would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
(Change of Rights Agent). 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)    Prior Countersignatures. 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)    Legal Counsel. 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 to be taken by it in good faith and in
accordance with such opinion.

              (b)    Certification by the Company. 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 herein
specifically prescribed) may be deemed to be conclusively proved and established
by a certificate signed by the President, any Vice President, the Secretary, any
Assistant Secretary, the Treasurer or any Assistant Treasurer 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.




                                       35

<PAGE>   41



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

              (d)    Statements of Fact or Recitals. 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)    Agreement; Adjustments. The Rights Agent shall not be under
any responsibility in respect of the validity of this Agreement or the execution
and delivery hereof (except the due execution hereof by the Rights Agent) or in
respect of the validity or execution of any Rights Certificate (except its
countersignature); nor shall it be responsible for any breach by the Company of
any covenant or condition contained in this Agreement or in any Rights
Certificate; nor shall it be responsible for any adjustment required under the
provisions of Section 11 (Adjustment of Purchase Price; Number and Kind of
Shares or Number of Rights) or Section 13 (Consolidation, Merger or Sale or
Transfer of Assets or Earning Power) or responsible for the manner, method or
amount of any such adjustment or the ascertaining of the existence of facts that
would require any such adjustment (except with respect to the exercise of Rights
evidenced by Rights Certificates after actual notice of any such adjustment);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Common Stock or
Preferred Stock to be issued pursuant to this Agreement or any Rights
Certificate or as to whether any shares of Common Stock or Preferred Stock will,
when so issued, be validly authorized and issued, fully paid and nonassessable.

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

              (g)    Instructions. The Rights Agent is hereby authorized and
directed to accept instructions with respect to the performance of its duties
hereunder from the President, any Vice President, the Secretary, any Assistant
Secretary, the Treasurer or any Assistant Treasurer of the Company and to apply
to such persons 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 the instructions of any such person.

              (h)    Dealing in Rights. The Rights Agent and any stockholder,
director, officer or employee of the Rights Agent may buy, sell or deal in any
of the Rights or other securities of the Company or become pecuniarily
interested in any transaction in which



                                       36

<PAGE>   42



the Company may be interested, or contract with or lend money to the Company or
otherwise act as fully and freely as though it were not Rights Agent under this
Agreement. Nothing herein shall preclude the Rights Agent from acting in any
other capacity for the Company or for any other legal entity.

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

              (j)    Expenses; Repayment Assurances. 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
hereunder or in the exercise of its rights if there shall be reasonable grounds
for believing that repayment of such funds or adequate indemnification against
such risk or liability is not reasonably assured to it.

              (k)    Exercise of Rights; Consultation with Company. 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 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 of
transfer without first consulting with the Company.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty (30) calendar days' notice in writing mailed to the Company, and to
each transfer agent of the Common Stock and Preferred Stock, by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) calendar days' notice in writing, mailed to the Rights Agent or
successor Rights Agent, as the case may be, and to each transfer agent of the
Common Stock and Preferred Stock, by registered or certified mail, and to the
holders of the Rights Certificates by first-class mail. If the Rights Agent
shall resign or be removed or shall otherwise become incapable of acting, the
Company shall appoint a successor to the Rights Agent. If the Company shall fail
to make such appointment within a period of thirty (30) calendar days after
giving notice of such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then the registered holder of
any Rights Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court, shall be (a) a



                                       37

<PAGE>   43



corporation organized and doing business under the laws of the United States or
of any State of the United States, in good standing, which is authorized under
such laws to exercise stock transfer or corporate trust powers, is subject to
supervision or examination by federal or state authority and has at the time of
its appointment as Rights Agent a combined capital and surplus of at least
$50,000,000 or (b) an Affiliate of a corporation described in clause (a) of this
sentence. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Stock
and the Preferred Stock, and mail a notice thereof in writing to the registered
holders of the Rights Certificates. Failure to give any notice provided for in
this Section 21 (Change of Rights Agent), or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by the Board to reflect any adjustment or change in the
Purchase Price and the number or kind or class of shares or other securities or
property purchasable under the Rights Certificates made in accordance with the
provisions of this Agreement. In addition, in connection with the issuance or
sale of shares of Common Stock following the Distribution Date and prior to the
redemption or expiration of the Rights, the Company (a) shall, with respect to
shares of Common Stock so issued or sold pursuant to the exercise of stock
options or under any employee plan or arrangement, or upon the exercise,
conversion or exchange of securities hereafter issued by the Company, in either
case outstanding as of the Distribution Date, and (b) may, in any other case, if
deemed necessary or appropriate by the Board, issue Rights Certificates
representing the appropriate number of Rights in connection with such issuance
or sale; provided, however, that (i) no such Rights Certificate shall be issued
if, and to the extent that, the Company shall be advised by counsel that such
issuance would create a significant risk of material, adverse tax consequences
to the Company or the Person to whom such Rights Certificate would be issued,
and (ii) no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

         Section 23. Redemption and Termination.

              (a)    Redemption. The Company may, at its option, at any time 
prior to the earlier of (i) the Stock Acquisition Date, or (ii) the Final
Expiration Date, redeem



                                       38

<PAGE>   44



(the date of such redemption being referred to herein as the "Redemption Date")
all but not less than all of the then outstanding Rights at a redemption price
of $0.01 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 hereinafter referred to as the "Redemption
Price"). The redemption of the Rights by the Company may be made effective at
such time, on such basis and with such conditions as the Board in its sole
discretion may establish. The Company may, at its option, pay the Redemption
Price in cash, shares of Common Stock (based on the Current Market Price of the
Common Stock at the time of redemption) or any other form of consideration
deemed appropriate by Board.

              (b)    Effect of Redemption; Procedure. Immediately upon the 
action of the Company ordering the redemption of the Rights and without any
further action and without any notice, the right to exercise the Rights will
terminate and the only right thereafter of the holders of Rights shall be to
receive the Redemption Price for each Right so held. Promptly after the
Redemption Date, the Company shall (i) give notice of such redemption to the
Rights Agent, (ii) give public notice of such redemption; provided, however,
that the failure to give, or any defect in, such notice shall not affect the
validity of such redemption, and (iii) mail notice of such redemption to the
holders of the then outstanding Rights at their last addresses as they appear
upon the registry books of the Rights Agent or, prior to the Distribution Date,
on the registry books of the Transfer Agent for the Common 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. Amounts
payable shall be rounded down to the nearest $0.01.

         Section 24. Exchange.

              (a)    Right to Exchange. The Company may, at its option, at any
time and from time to time after the first occurrence of a Flip-in Event,
exchange all or part of the then outstanding and exercisable Rights (other than
Rights which have become void as provided in Section 7(e) (Exercise of Rights;
Purchase Price; Expiration Date of Rights -- Termination of Acquiring Person's
Rights)) for the Exchange Number of shares of Common Stock, shares or units of
Preferred Stock which the Board has determined to be a Common Stock Equivalent,
units of other property or any combination thereof as determined by the Board.
Notwithstanding the foregoing, the Company shall not be empowered to effect such
exchange at any time after any Person (other than the Company, any Subsidiary of
the Company, any employee benefit plan of the Company or any such Subsidiary or
any entity holding shares of Common Stock for or pursuant to any such plan),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the shares of Common Stock then outstanding.
The exchange of the Rights by the Company may be made effective at such time, on
such basis and with such conditions as the Board in its sole discretion may
establish.



                                       39

<PAGE>   45



              (b)    Effect of Exchange; Procedure. Immediately upon the action
of the Company ordering the exchange of any Rights pursuant to paragraph (a) of
this Section 24, evidence of which shall have been filed with the Rights Agent
and without any further action and without any notice, the right to exercise
such Rights will terminate and the only right thereafter of a holder of such
Rights shall be to receive that number of shares of Common Stock, Common Stock
Equivalents or units of other property equal to the number of such Rights held
by such holder multiplied by the Exchange Number. Promptly after the action of
the Company ordering the exchange of the Rights, the Company shall (i) file
evidence of such action with the Rights Agent, (ii) give public notice of such
exchange; provided, however, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange, and (iii) mail notice of
such exchange to the holders of such Rights at their last addresses as they
appear upon the registry books of the Rights Agent. Any notice which is mailed
in the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of exchange will state the method by which
the exchange will be effected and, in the event of any partial exchange, the
number of Rights which will be exchanged. Any partial exchange shall be effected
pro rata based on the number of Rights (other than Rights which have become void
as provided in Section 7(e) (Exercise of Rights; Purchase Price; Expiration Date
of Rights -- Termination of Acquiring Person's Rights)) held by each holder of
Rights.

              (c)    Common Stock Equivalents. In any exchange pursuant to this
Section 24, the Company, at its option, may substitute Common Stock Equivalents
for Common Stock exchangeable for Rights, at the initial rate of one share of
Common Stock Equivalent for each share of Common Stock, as appropriately
adjusted to reflect adjustments in the voting rights of the Common Stock
pursuant to the Company's Certificate of Incorporation, so that the share of
Common Stock Equivalent delivered in lieu of each share of Common Stock shall
have the same voting rights as one share of Common Stock.

              (d)    Insufficient Common Stock. In the event that the number of
shares of Common Stock which are authorized by the Company's Certificate of
Incorporation but not outstanding or reserved for issuance for purposes other
than upon exercise of the Rights is not sufficient to permit any exchange of
Rights in accordance with this Section 24, the Company may, at its option, take
all such action as may be necessary to authorize additional shares of Common
Stock for issuance upon such exchange.

              (e)    Fractional Shares. Upon the action of the Company ordering
the exchange of any Rights pursuant to paragraph (a) of this Section 24, the
Company shall not be required to issue fractions of shares or to distribute
certificates which evidence fractional shares. In lieu of such fractional
shares, the Company may pay to the registered holders of the Rights Certificates
with regard to which such fractional shares would otherwise be issuable an
amount in cash equal to the same fraction of the current market value of one
share of Common Stock. For purposes of this Section 24, the current



                                       40

<PAGE>   46



market value of one share of Common Stock shall be the closing price of one
share of Common Stock (as determined pursuant to Section 11(d)(i) (Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights -- Current Market
Price)) for the Trading Day immediately prior to the date of exchange pursuant
to this Section 24, and the value of any Common Stock Equivalent shall be deemed
to have the same current market value as the Common Stock on such date.

         Section 25. Notice of Certain Events.

              (a)    Preferred Stock Transactions, etc. 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 (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 its Preferred Stock (other than a reclassification involving
only the subdivision of outstanding shares of Preferred Stock); (iv) to effect
any consolidation with, merger into or with, or statutory share exchange or
similar transaction with, any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) (Adjustment of
Purchase Price; Number and Kind of Shares or Number of Rights -- Restriction
against Diminishing Benefits of the Rights)), or to effect any sale or other
transfer (or to permit one or more of its Subsidiaries to effect any sale or
other transfer), in one transaction or a series of related transactions, of more
than 50% of the assets, cash flow 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)); (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the shares
of Common Stock payable in Common Stock or to effect a subdivision, combination
or consolidation of the shares of Common Stock (by reclassification or otherwise
than by payment of dividends in Common Stock), then, in each such case, the
Company shall give to each holder of a Rights Certificate, to the extent
feasible and in accordance with Section 26 (Notices), 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, statutory share exchange or similar
transaction, 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) calendar 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) calendar 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.



                                       41

<PAGE>   47



              (b)    Other Transactions. In case any of the events set forth in
Section 11(a)(ii) (Adjustment of Purchase Price; Number and Kind of Shares or
Number of Rights -- Certain Adjustments) shall occur, then, in any such case,
(i) 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 26
(Notices), 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), and (ii) all references in the preceding paragraph to Preferred Stock
shall be deemed thereafter to refer to Common Stock and/or, if appropriate,
other securities.

         Section 26. Notices. Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Rights Certificate
to or on the Company shall be sufficiently given or made if sent by telecopier
(with receipt confirmed) or by first-class mail, postage prepaid, addressed

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

                              The Bank of New York
                              101 Barclay Street

                              Telecopier: (212) 815-3201

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

         Section 27. Supplements and Amendments. For so long as the Rights are
redeemable, and subject to the penultimate sentence of this Section 27, the
Company may, 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



                                       42

<PAGE>   48



representing shares of Common Stock or, on and after the Distribution Date, the
holders of Rights Certificates. At any time when the Rights are no longer
redeemable and subject to the penultimate sentence of this Section 27, 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;
provided, however, that no such supplement or amendment may (i) adversely affect
the interests of the holders of Rights Certificates (other than an Acquiring
Person or an Affiliate or Associate of any such Person) or, prior to the
Distribution Date, holders of certificates representing shares of Common Stock;
(ii) cause this Agreement again to become amendable other than in accordance
with this sentence; or (iii) cause the Rights again to become redeemable. 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 27, the Rights Agent shall execute such supplement or amendment.
Notwithstanding anything contained in this Agreement to the contrary, no
supplement or amendment shall be made which changes the Redemption Price, the
Final Expiration Date, the Purchase Price, or the number of one one-hundredths
of a share of Preferred Stock for which a right is exercisable; provided,
however, that at any time prior to (i) a Stock Acquisition Date or (ii) the date
that a tender or exchange offer by any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or any
Subsidiary of the Company, or any Person or entity organized, appointed or
established by the Company for or pursuant to the terms of any such plan) is
first published or sent or given within the meaning of Rule 14d-2(a) of the
General Rules and Regulations under the Exchange Act, if upon consummation
thereof, such Person would be the Beneficial Owner of 12% or more of the shares
of Common Stock then outstanding, the Board may amend this Agreement to increase
the Purchase Price or extend the Final Expiration Date. Prior to the
Distribution Date, the interests of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Stock.

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

         Section 29. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common Stock
of which any Person is the Beneficial Owner, shall be made in accordance with
the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations
under the Exchange Act. The Board shall have the exclusive power and authority
to administer this Agreement and to exercise all rights and powers specifically
granted to the Board or to the Company, or as may be necessary or advisable in
the administration of this Agreement, including, without limitation, the right
and power to (i) interpret the provisions of this Agreement, and (ii) make all
determinations deemed necessary or advisable for the administration of this



                                       43

<PAGE>   49



Agreement (including a determination to redeem or not redeem the Rights or to
amend the 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 to
any liability to the holders of the Rights.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of the Common Stock) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock).

         Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
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 Board determines
in its good faith judgment that severing the invalid language from this
Agreement would adversely affect the purpose or effect of this Agreement, the
right of redemption set forth in Section 23 (Redemption and Termination) 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 Board.

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

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

         Section 34. Descriptive Headings. Descriptive headings of the several
Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                           TRINITY INDUSTRIES, INC.

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware

     We, W. Ray Wallace, President of Trinity Industries Inc., a corporation
organized and existing under the General Corporation Law of the State of
Delaware, and J. J. French, Jr., Secretary in accordance with the provisions of
Section 151 thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the Corporation and the General Corporation
Law of Delaware, the Board of Directors on April 11, 1989, adopted the
following resolution creating a series of 250,000 shares of Preferred Stock
designated as Series A Junior Participating Preferred Stock:

          RESOLVED, that pursuant to the authority vested in the Board of
     Directors of this Corporation in accordance with the provisions of its
     Certificate of Incorporation and the General Corporation Law of Delaware,
     a series of Preferred Stock of the Corporation be and it hereby is
     created, and that the designation and amount thereof and the voting
     powers, preferences and relative, participating, optional and other
     special rights of the shares of such series, and the qualifications,
     limitations or restrictions thereof are as follows:

                                   SECTION 1
                             DESIGNATION AND AMOUNT

     The shares of such series shall be designated as "Series A Junior
Participating Preferred Stock" and the number of shares constituting such
series shall be 250,000.

                                   SECTION 2
                          DIVIDENDS AND DISTRIBUTIONS

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


<PAGE>   53
shares of Series A Junior Participating Preferred Stock with respect to
dividends, the holders of shares of Series A Junior Participating. Preferred
Stock shall be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available for the purpose, quarterly dividends
payable in cash on the last day of January, April July and October in each year
(each such date being referred to herein as a "Quarterly Dividend Payment
Date"), commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A Junior Participating
Preferred Stock, in an amount per share (rounded to the nearest cent) equal to
the greater of (a) $4.25 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per amount of all cash dividends,
and 100 times the aggregate per share amount (Payable in kind) of all, non-cash
dividends or other distributions other than a dividend payable in shares of
Common Stock or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock, par value $1.00
per share, of the Corporation (the "Common Stock") since the immediately
preceding Quarterly Dividend Payment Date, or, with respect to the first
Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Junior Participating Preferred Stock. In the
event the Corporation shall at any time after April 11, 1989 (the "Rights
Declaration Date") (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount to which holders of shares of Series A Junior Participating Preferred
Stock were entitled immediately prior to such event under clause (b) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction,
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     (B) The Corporation shall declare a dividend or distribution on the Series
A Junior Participating Preferred Stock as provided in paragraph (A) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in
the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the
next subsequent Quarterly Dividend Payment Date, a dividend of $4.25 per share
on the Series A Junior Participating Preferred Stock shall nevertheless be
payable on such subsequent Quarterly Dividend Payment Date.


                                       2
<PAGE>   54
 (C) Dividends shall begin to accrue and be cumulative on outstanding shares of
Series A Junior Participating Preferred Stock from the Quarterly Dividend
Payment Date preceding the date of issue of such shares of Series A Junior
Participating Preferred Stock, unless the date of issue of such shares is prior
to the record date for the first Quarterly Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a
date after the record date for the determination of holders of shares of Series
A Junior Participating Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends
paid on the shares of Series A Junior Participating Preferred Stock in an amount
less than the total amount of such dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. The Board of Directors may fix a record date for
the determination of holders of shares of Series A Junior Participating
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
                                 VOTING RIGHTS

     The holders of shares of Series A Junior Participating Preferred Stock
shall have the following voting rights:

     (A) In addition to such voting rights as may from time to time be required
by the laws of Delaware, the holders of Preferred Stock shall vote at such
times as holders of Common Stock may vote and in a like manner, one vote for
each share of stock held, and all shares of the corporation shall be voted as a
single class, except where specifically required by law to vote separately.

                                   SECTION 4
                              CERTAIN RESTRICTIONS

     (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Junior Participating Preferred Stock


                                       3

<PAGE>   55

as provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Junior Participating Preferred Stock shall have been paid in full,
the Corporation shall not:

          (i) declare or pay dividends on, make any other distributions on
     (other than dividends or distributions in shares of stock junior to the
     Series A Junior Participating Preferred Stock), or redeem or purchase or
     otherwise acquire for consideration any shares of stock ranking junior
     (either as to dividends or upon liquidation, dissolution or winding up)
     to the Series A Junior Participating Preferred Stock;

          (ii) declare or pay dividends on or make any other distributions on
     (other than dividends or distributions in shares of stock junior to the
     Series A Junior Participating Preferred Stock) any shares of stock ranking
     on a parity (either as to dividends or upon liquidation, dissolution or
     winding up) with the Series A Junior Participating Preferred Stock, except
     dividends paid ratably on the Series A Junior Participating Preferred
     Stock and all such parity stock on which dividends are payable or in
     arrears in proportion to the total amounts to which the holders of all
     such shares are then entitled;

          (iii) except as permitted by subparagraph (iv) immediately below,
     redeem or purchase or otherwise acquire for consideration shares of any
     stock ranking on a parity (either as to dividends or upon liquidation,
     dissolution or winding up) with the Series A Junior Participating
     Preferred Stock, provided that the Corporation may at any time redeem,
     purchase or otherwise acquire shares of any such parity stock in exchange
     for shares of any stock of the Corporation ranking junior (either as to
     dividends or upon dissolution, liquidation or winding up) to the Series A
     Junior Participating Preferred Stock; or

          (iv) purchase or otherwise acquire for consideration any shares of
     Series A Junior Participating Preferred Stock, or any shares of stock
     ranking on a parity with the Series A Junior Participating Preferred
     Stock, except in accordance with a purchase offer made in writing or by
     publication (as determined by the Board of Directors) to all holders of
     such shares upon such terms as the Board of Directors, after consideration
     of the respective annual dividend rates and other relative rights and
     preferences of the respective series and


                                       4
<PAGE>   56

     classes, shall determine in good faith will result in fair and equitable
     treatment among the respective series or classes.

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

                                   SECTION 5
                               REACQUIRED SHARES

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

                                   SECTION 6
                    LIQUIDATION, DISSOLUTION OR WINDING UP

     (A) Upon any liquidation (voluntary or otherwise), dissolution or winding
up of the Corporation, no distribution shall be made to the holders of shares
of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred Stock
unless, prior thereto, the holders of shares of Series A Junior Participating
Preferred Stock shall have received the greater of (a) $100.00 per share, plus
an amount equal to accrued and unpaid dividends and distributions thereon,
whether or not declared, to the date of such payment or (b) an amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
100 times the aggregate amount to be distributed per share to holders of Common
Stock. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such
case the amount to which holders of shares of Series A Participating Junior
Preferred Stock were entitled immediately prior to such event pursuant to
clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction of the numerator of which is the number of shares of
Common


                                       5
<PAGE>   57

Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     (B) In the event, however, that there are not sufficient assets available
to permit payment in full of the Series A liquidation Preference and the
liquidation preferences of all other series of Preferred Stock, if any, which
rank on a parity with the Series A Junior Participating Preferred Stock, then
such assets shall be distributed ratably to the holders of such parity shares in
proportion to their respective liquidation preferences.

                                   SECTION 7
                          CONSOLIDATION, MERGER, ETC.

     In case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common Stock are
exchanged for or changed into other stock or securities, cash and/or any other
property, then in any such case the sham of Series A Junior Participating
Preferred Stock shall at the same time be similarly exchanged or changed into
an amount per share (subject to the provision for adjustment hereinafter set
forth) equal to 100 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is changed or exchanged. In the event the
Corporation shall at any time after the Rights Declaration Date (i) declare
any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide
the outstanding Common Stock, or (iii) combine the outstanding Common Stock
into a smaller number of shares, then in each such case the amount set forth in
the preceding sentence with respect to the exchange or change of shares of
Series A Junior Participating Preferred Stock shall be adjusted by multiplying
such amount by a fraction, the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

                                   SECTION 8
                              OPTIONAL REDEMPTION

     (A) The Company shall have the option to redeem the whole or any part of
the Series A Junior Participating Preferred Stock at any time at a redemption
price equal to 100 times the "current per share market price" of the Common
Stock on the date of the mailing of the notice of redemption, plus unpaid
accumulated dividends to the date of such


                                       6
<PAGE>   58
 redemption. in the event the Company shall at any time after the Rights
Declaration Date, (ii) declare any dividend on Common Stock, payable in shares
of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine
the outstanding Common Stock into a smaller number of shares, then in each such
case the amount to which holders of shares of Series A Junior Participation
Preferred Stock were otherwise entitled immediately prior to such event shall be
adjusted by such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. The "current per share market
price" on any date shall be deemed to be the average of the closing price per
share of such Common Stock for the 10 consecutive Trading Days (as such term is
hereinafter defined) immediately prior to such date. The closing price for each
day shall be the last sale price, regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked prices, regular way,
in either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the Common Stock is not listed or admitted to trading on
the New York Stock Exchange, as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the principal national securities exchange on which the Common Stock
is listed or admitted to trading or, if the Common Stock is 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 National Association of Securities
Dealers, Inc. Automated Quotation System or such other system then in use or, if
on any such date the Common Stock is not quoted by any such organization, the
average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Common Stock selected by the Board of
Directors of the Company. If on such date no such market maker is making a
market in the Common Stock, the fair value of the Common Stock on such date as
determined in good faith by the Board of Directors of the Company shall be used.
The term "Trading Day" shall mean a day on which the principal national
securities exchange on which the Common Stock is listed or admitted to trading
is open for the transaction of business or, if the Common Stock is not listed or
admitted to trading on any national securities exchange, a Monday, Tuesday,
Wednesday, Thursday or Friday on which banking institutions in the State of
Delaware are not authorized or obligated by law or executive order to close.

<PAGE>   59

     (B) Notice of any such redemption shall be given by mailing to the holders
of the Series A Junior Participating Preference Stock a notice of such
redemption, first class postage prepaid, not later than the thirtieth day and
not earlier than the sixtieth day before the date fixed for redemption, at
their last address as the same shall appear upon the books of the Company. Any
notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the shareholder received such
notice, and failure duly to give such notice by mail, or any defect in such
notice to any holder of Series A Junior Participating Preferred Stock shall not
affect the validity of the proceedings for the redemption of such Series A
Junior Participating Preferred Stock.

     (C) If less than all the outstanding shares of the Series A Junior 
Participating Preference Stock are to be redeemed, the number of shares to be
redeemed shall be determined by the Board of Directors and the shares to be
redeemed shall be determined by lot or pro rata or in such fair and equitable
other manner as may be prescribed by resolution of the Board of Directors.

     (D) The notice of redemption to each holder of Series A Junior 
Participating Preference Stock shall specify (a) the number of shares of Series
A Junior Participating Preference Stock of such holder to be redeemed, (b) the
date fixed for redemption, (c) the redemption price and (d) the place of
payment of the redemption price.

     (E) If any such notice of redemption shall have been duly given or if the
Company shall have given to the bank or trust company hereinafter referred to
irrevocable written authorization promptly to give or complete such notice, and
if on or before the redemption date specified therein the funds necessary for
such redemption shall have been deposited by the Company with the bank or trust
company designated in such notice, doing business in the United States of
America and having a capital surplus and undivided profits aggregating at least
$25,000,000 according to its last published statement of condition, in trust
for the benefit of the holders of Series A Junior Participating Preferred Stock
called for redemption, then, notwithstanding that any certificate for such
shares so called for redemption shall not have been surrendered for
cancellation, from and after the time of such deposit all such shares called
for redemption shall no longer be deemed outstanding and all rights with
respect to such shares shall no longer be deemed outstanding and all rights
with respect to such shares shall forthwith cease and terminate, except the
right of the holders thereof to receive from such bank or trust company at any
time after the time of such deposit the funds so deposited, without interest,
and the right to


                                       8
<PAGE>   60
exercise, up to the close of business on the fifth day before the date fixed
for redemption, all privileges of conversion or exchange, if any. In case less
than all the shares represented by any surrendered certificate are redeemed, a
new certificate shall be issued representing the unredeemed shares. Any interest
accrued on such funds shall be paid to the Company from time to time. Any funds
so deposited and unclaimed at the end of six years from such redemption date
shall be repaid to the Company, after which the holders of shares of Series A
Junior Participating Preferred Stock called for redemption shall look only to
the Company for payment thereof; provided that any funds so deposited which
shall not be required for redemption because of the exercise of any privilege of
conversion or exchange subsequent to the date of deposit shall be repaid to the
Company forthwith.

                                   SECTION 9
                                    RANKING

     The Series A Junior Participating Preferred Stock shall rank junior to all
other series of the Corporation's Preferred Stock as to the payment of dividends
and the distribution of assets, unless the terms of any such series shall
provide otherwise.

                                  SECTION 10
                                   AMENDMENT

     So long as any shares of Series A Junior Participating Preferred Stock are
outstanding, the Certificate of Incorporation of the Corporation shall not be
further amended in any manner which would materially alter or change the
powers, preferences or special rights of the Series A Junior Participating
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority or more of the outstanding shares of Series A Junior
Participating Preferred Stock, voting separately as a class.

                                   SECTION 11
                               FRACTIONAL SHARES

     Series A Junior Participating Preferred Stock may be issued in fractions
of a share which shall entitle the holder, in proportion to such holders'
fractional shares, to exercise voting rights, receive dividends, participate in
distributions and to have the benefit of all other rights of holders of Series
A Junior Participating Preferred Stock.

     Pursuant to Section 151 of the General Corporation Law of the State of
Delaware, the undersigned authorized officer of Trinity Industries, Inc. (the
"Corporation"), on behalf of the Corporation, DOES HEREBY CERTIFY

     That no shares of Preferred Stock of the Corporation designated as Series
A Junior Participating Preferred Stock have been issued.

     That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the Corporation and the General Corporation
Law of the State of Delaware, the Board of Directors on March 11, 1999, adopted

          RESOLVED, that pursuant to the authority vested in the Board of
     Directors in accordance with the provisions of the Corporation's
     Certificate of Incorporation and the General Corporation Law of the State
     of Delaware, Section 2 of the Certificate of Designations, Preferences and
     Rights of Series A Junior Participating Preferred Stock setting forth the
     designation and amount and the voting powers, preferences and relative,
     participating, optional and other special rights of the shares of, and the
     qualifications, limitations and restrictions of the Corporation's series
     of Preferred Stock designated as "Series A Junior Participating Preferred
     Stock" is deleted and replaced in its entirety with a new Section 2 that
     reads as follows:

<PAGE>   63

                                   "SECTION 2
                          DIVIDENDS AND DISTRIBUTIONS

          (A) Subject to the prior and superior rights of the holders of any
     shares of any series of Preferred Stock ranking prior and superior to the
     shares of Series A Junior Participating Preferred Stock with respect to
     dividends, the holders of shares of Series A Junior Participating
     Preferred Stock shall be entitled to receive, when, as and if declared by
     the Board of Directors out of funds legally available for the purpose,
     quarterly dividends payable in cash on the last day of January, April,
     July and October in each year (each such date being referred to herein as
     a "Quarterly Dividend Payment Date"), commencing on the first Quarterly
     Dividend Payment Date after the first issuance of a share or fraction of a
     share of Series A Junior Participating Preferred Stock, in an amount per
     share (rounded to the nearest cent) equal to the greater of (a) $4.25 or
     (b) subject to the provision for adjustment hereinafter set forth, 100
     times the aggregate per share amount of all cash dividends, and 100 times
     the aggregate per share amount (payable in kind) of all, non-cash
     dividends or other distributions other than a dividend payable in shares
     of Common Stock or a subdivision of the outstanding shares of common Stock
     (by reclassification or otherwise), declared on the Common Stock, par
     value $1.00 per share, of the Corporation (the "Common Stock") since the
     immediately preceding Quarterly Dividend Payment Date, or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Series A Junior Participating Preferred
     Stock. In the event the Corporation shall at any time after March 11, 1999
     (the "Rights Declaration Date") (i) declare any dividend on Common Stock
     payable in shares of Common Stock, (ii) subdivide the outstanding Common
     Stock, or (iii) combine the outstanding Common Stock into a smaller number
     of shares, then in each such case the amount to which holders of shares of
     Series A Junior Participating Preferred Stock were entitled immediately
     prior to such event under clause (b) of the preceding sentence shall be
     adjusted by multiplying such amount by a fraction, the numerator of which
     is the number of shares of Common Stock outstanding immediately after such
     event and the


                                      -2-
<PAGE>   64

     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          (B) The Corporation shall declare a dividend or distribution on the
     Series A Junior Participating Preferred Stock as provided in paragraph (A)
     above immediately after it declares a dividend or distribution on the
     Common Stock (other than a dividend payable in shares of Common Stock);
     provided that, in the event no dividend or distribution shall have been
     declared on the Common Stock during the period between any Quarterly
     Dividend Payment Date and the next subsequent Quarterly Dividend Payment
     Date, a dividend of $4.25 per share on the Series A Junior Participating
     Preferred Stock shall nevertheless be payable on such subsequent Quarterly
     Dividend Payment Date.

          (C) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Junior Participating Preferred Stock from the Quarterly
     Dividend Payment Date next preceding the date of issue of such shares of
     Series A Junior Participating Preferred Stock, unless the date of issue of
     such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Junior Participating
     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 by unpaid dividends shall not bear interest.
     Dividends paid on the shares of Series A Junior Participating Preferred
     Stock in an amount less than the total amount of such dividends at the
     time accrued and payable on such shares shall be allocated pro rata on a
     share-by-share basis among all such shares at the time outstanding. The
     Board of Directors may fix a record date for the determination of holders
     of shares of Series A Junior Participating 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."

     and, be it

          RESOLVED FURTHER, that pursuant to the authority vested in the Board
     of Directors in accordance with the provisions of the Corporation's
     Certificate of Incorporation and the General Corporation Law of the State
     of Delaware, the number of authorized shares of Preferred Stock of the
     Corporation designated as Series A Junior Participating Preferred Stock
     be, and it hereby is, increased from 300,000 shares to 1,000,000 shares.

     IN WITNESS WHEREOF, I have executed this certificate as of March 11, 1999.

Junior Participating Preferred Stock (the "Preferred Stock") of the Corporation,
at a purchase price of $ per one one-hundredth (1/100) of a share (the "Purchase
Price"), upon presentation and surrender of this Rights Certificate with the
Form of Election to Purchase and related Certificate duly executed. The number
of Rights evidenced by this Rights Certificate (and the number of shares which
may be purchased upon exercise thereof) set forth above, and the Purchase Price
set forth above, are the number and Purchase Price as of ________ __, ____,
based on the Preferred Stock as constituted at such date. The Corporation
reserves the right to require prior to the occurrence of a Triggering Event (as
such term is defined in the Rights Agreement) that upon any exercise of Rights,
a number of Rights be exercised so that only whole shares of Preferred Stock
would be issued.

         Upon the occurrence of a Flip-in Event (as such term is defined in the
Rights Agreement), if the Rights evidenced by this Rights Certificate are
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate or
any such Person (as such terms are defined in the Rights Agreement), (ii) a
transferee of an Acquiring Person or its Associate or Affiliate who becomes a
transferee after such Acquiring Person or its Associate or Affiliate becomes
such, or (iii) under certain circumstances specified in the Rights Agreement, a
transferee of an Acquiring Person or its Associate or Affiliate who becomes a
transferee prior to or concurrently with the Acquiring Person becoming such,
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 Flip-in Event.

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

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Corporation and the holders of the Rights Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the above-mentioned office of the
Rights Agent and are also available upon written request to the Rights Agent.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the principal office or offices of the Rights Agent designated
for such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of one one-


                                       48

<PAGE>   68

hundredths of a share of Preferred Stock as the Rights evidenced by the Rights
Certificate or Rights Certificates surrendered shall have entitled such holder
to purchase. If this Rights Certificate shall be exercised in part, the holder
shall be entitled to receive upon surrender hereof another Rights Certificate or
Rights Certificates for the number of whole Rights for which this Rights
Certificate is not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate (i) may be redeemed by the Corporation at its option at a
redemption price of $0.01 per Right at any time prior to the earlier of (a) the
Stock Acquisition Date (as such term is defined in the Rights Agreement) or (b)
the Final Expiration Date (as such term is defined in the Rights Agreement) and
(ii) may be exchanged in whole or in part for Preferred Stock, shares of the
Corporation's Common Stock, par value $1.00 per share, other property or any
combination thereof.

         In addition, the Rights may be exchanged, in whole or in part, for
shares of the Common Stock, or shares of common stock equivalents of the
Corporation having essentially the same value or economic rights as such shares.
Immediately upon the action of the Board of Directors of the Corporation
authorizing any such exchange, and without any further action or any notice, the
Rights (other than Rights which are not subject to such exchange) will terminate
and the Rights will only enable holders to receive the shares issuable upon such
exchange.

         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 (1/100) of a share of Preferred Stock,
which may, at the election of the Corporation, be evidenced by depositary
receipts), but a cash payment will be made in lieu thereof, as provided in the
Rights Agreement.

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

         This Rights Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.

[Letter to Stockholders]


                              ___________ __, 1999




Dear Trinity Industries Stockholder:

      On March 11, 1999, your Board of Directors adopted a Stockholder Rights
Plan designed to prevent a potential acquiror from gaining control of the
Company without fairly compensating all of the Company's stockholders. The
Stockholder Rights Plan replaces a similar Stockholders Rights Plan that expired
on April 27, 1999.

      The Rights will initially trade with shares of the Company's Common Stock
and will have no impact on the way in which the Company's shares are traded.
There are no separate certificates or market for the Rights.

      The Rights will not become exercisable and trade separately from the
Common Stock until the earlier of (1) ten business days after a public
announcement that a person has acquired 12% or more of the Common Stock of the
Company or (2) ten business days (or any later date determined by the Company's
Board of Directors) after a person makes a tender or exchange offer for 12% or
more of the Company's Common Stock.

      Many other public companies have adopted similar plans, indicating
widespread agreement that such plans can help Directors deflect coercive and
inadequate offers.

      A summary of the terms of the Rights is included with this letter.

                                               Sincerely,



                                               Timothy R. Wallace
                                               Chairman, President and
                                               Chief Executive Officer

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK

         On March 11, 1999, the Board of Directors of Trinity Industries, Inc.
(the "Company") declared a dividend distribution of one Right for each
outstanding share of the Company's common stock, $1.00 par value (the "Common
Stock"), to stockholders of record at the close of business on April 27, 1999.
Each Right entitles the registered holder to purchase from the Company one
one-hundredth (1/100) of a share of Series A Preferred Stock, par value $1.00
(the "Preferred Stock"), at a Purchase Price of $200.00 per one one-hundredth
(1/100) of a share, subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") between the
Company and The Bank of New York, as Rights Agent (the "Rights Agent").

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock upon the earlier
of (i) ten (10) business days following a public announcement that a person or
group of affiliated or associated persons (an "Acquiring Person") has acquired,
or obtained the right to acquire, beneficial ownership of twelve percent (12%)
or more of the outstanding shares of Common Stock (the "Stock Acquisition
Date"), or (ii) ten (10) business days (or such later date as the Board of
Directors shall determine) following the commencement of a tender or exchange
offer that would result in a person or group beneficially owning twelve percent
(12%) or more of such outstanding shares of Common Stock. The date the Rights
separate is referred to as the "Distribution Date."


         Until the Distribution Date, (i) the Rights will be evidenced by the
Common Stock certificates and will be transferred with and only with such Common
Stock certificates, (ii) new Common Stock certificates issued after April 27,
1999 will contain a notation incorporating the Rights Agreement by reference,
and (iii) the surrender for transfer of any certificates for Common Stock
outstanding will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificates. Pursuant to the Rights Agreement,
the Company reserves the right to require prior to the occurrence of a
Triggering Event (as defined below) that, upon any exercise of Rights, a number
of Rights be exercised so that only whole shares of Preferred Stock will be
issued.

         The Rights are not exercisable until the Distribution Date and will
expire at the close of business on April 27, 2009, 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 the Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates will represent the Rights. Except in connection with shares of
Common Stock issued or sold pursuant to



                                       55

<PAGE>   75


the exercise of stock options under any employee plan or arrangements, or
upon the exercise, conversion or exchange of securities hereafter issued by the
Company, or as otherwise determined by the Board of Directors, only shares of
Common Stock issued prior to the Distribution Date will be issued with Rights.

         In the event that (i) the Company is the surviving corporation in a
merger or other business combination with an Acquiring Person (or any associate
or affiliate thereof) and its Common Stock remains outstanding and unchanged,
(ii) any person shall acquire beneficial ownership of more than twelve percent
(12%) of the outstanding shares of Common Stock (except pursuant to (A) certain
consolidations or mergers involving the Company or sales or transfers of the
combined assets, cash flow or earning power of the Company and its subsidiaries
or (B) an offer for all outstanding shares of Common Stock at a price and upon
terms and conditions which the Board of Directors determines to be in the best
interests of the Company and its stockholders), or (iii) there occurs a
reclassification of securities, a recapitalization of the Company or any of
certain business combinations or other transactions (other than certain
consolidations and mergers involving the Company and sales or transfers of the
combined assets, cash flow or earning power of the Company and its subsidiaries)
involving the Company or any of its subsidiaries which has the effect of
increasing by more than one percent (1%) the proportionate share of any class of
the outstanding equity securities of the Company or any of its subsidiaries
beneficially owned by an Acquiring Person (or any associate or affiliate
thereof), each holder of a Right (other than the Acquiring Person and certain
related parties) will thereafter have the right to receive, upon exercise,
Common Stock (or, in certain circumstances, cash, property or other securities
of the Company) having a value equal to two times the Purchase Price of the
Right. Notwithstanding any of the foregoing, following the occurrence of any of
the events described in this paragraph, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person will be null and void. The events described in this paragraph
are referred to as "Flip-in Events."

         For example, at a Purchase Price of $200 per Right, each Right not
owned by an Acquiring Person (or by certain related parties or transferees)
following an event set forth in the preceding paragraph would entitle its holder
to purchase $400 worth of Common Stock (or other consideration, as noted above)
for $200. Assuming that the Common Stock had a per share market price of $80 at
such time, the holder of each valid Right would be entitled to purchase five
shares of Common Stock for $200.

         In the event that, at any time following the Stock Acquisition Date,
(i) the Company shall enter into a merger or other business combination
transaction in which the Company is not the surviving corporation, (ii) the
Company is the surviving corporation in a consolidation, merger or similar
transaction pursuant to which all or part of the outstanding shares of Common
Stock are changed into or exchanged for stock or other securities of any other
person or cash or any other property or (iii) more than 50% of the combined
assets, cash flow or earning power of the Company and its

subsidiaries is sold or transferred (in each case other than certain
consolidations with, mergers with and into, or sales of assets, cash flow or
earning power by or to subsidiaries of the Company as specified in the Rights
Agreement), each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, common stock of the acquiring company having a value equal to two
times the Purchase Price of the Right. The events described in this paragraph
are referred to as "Flip-over Events." Flip-in Events and Flip-over Events are
referred to collectively as "Triggering Events."

         The Purchase Price payable, the number and kind of shares covered by
each Right and the number of Rights outstanding 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, options or warrants
to subscribe for Preferred Stock or securities convertible into Preferred Stock
at less than the current market price of the Preferred Stock, or (iii) upon the
distribution to holders of the Preferred Stock of evidences of indebtedness,
cash (excluding regular quarterly cash dividends), assets (other than dividends
payable in Preferred Stock) or subscription rights or warrants (other than those
referred to in (ii) immediately above).

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least one percent (1%) of the
Purchase Price. No fractional shares of Preferred Stock are required to be
issued (other than fractions which are integral multiples of one one-hundredth
(1/100) of a share of Preferred Stock) and, in lieu thereof, the Company may
make an adjustment in cash based on the market price of the Preferred Stock on
the trading date immediately prior to the date of exercise.

         At any time after any person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of fifty percent (50%) or more
of the outstanding shares of Common Stock, the Board of Directors of the Company
may, without payment of the Purchase Price by the holder, exchange the Rights
(other than Rights owned by such person or group, which will become void), in
whole or in part, for shares of Common Stock at an exchange ratio of one-half
(1/2) the number of shares of Common Stock (or in certain circumstances
Preferred Stock) for which a Right is exercisable immediately prior to the time
of the Company's decision to exchange the Rights (subject to adjustment).

         At any time until the Stock Acquisition Date, the Company may redeem
the Rights in whole, but not in part, at a price of $0.01 per Right (payable in
cash, shares of Common Stock or other consideration deemed appropriate by the
Board of Directors). Immediately upon the action of the Board of Directors
ordering redemption of the Rights, the Rights will terminate and the only right
of the holders of Rights will be to receive the $0.01 redemption price.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Common Stock (or other consideration) of the Company or for
common stock of an acquiring company as set forth above or in the event that the
Rights are redeemed.

         Other than those provisions relating to the principal economic terms of
the Rights, any of the provisions of the Rights Agreement may be amended by the
Board of Directors of the Company at any time during the period in which the
Rights are redeemable. At any time when the Rights are no longer redeemable, the
provisions of the Rights Agreement may be amended by the Board only if such
amendment does not adversely affect the interest of holders of Rights (excluding
the interest of any Acquiring Person); provided, however, that no amendment may
cause the Rights again to become redeemable.

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 8-A filed
on [March , 1999]. A copy of the Rights Agreement is available free of charge
from the Rights Agent. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
