Item 5.   Other Events.

              Adoption of Shareholder Rights Plan.

              On June 11, 1996, the Board of Directors of Tegal Corporation (the
"Company") declared a dividend of one right (a "Right") for each share of common
stock, $.01 par value (the "Common Shares"), of the Company outstanding at the
close of business on July 1, 1996 (the "Record Date"). As long as the Rights are
attached to the Common Shares, the Company will issue one Right (subject to
adjustment) with each new Common Share so that all such shares will have
attached Rights. When exercisable, each Right will entitle the registered holder
to purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock (the "Preferred Shares") at a price of $45.00 per
one one-hundredth of a Preferred Share, subject to adjustment (the "Purchase
Price"). The description and terms of the Rights are set forth in a Rights
Agreement, dated as of June 11, 1996, as the same may be amended from time to
time (the "Rights Agreement"), between the Company and ChaseMellon Shareholder
Services, L.L.C., as Rights Agent (the "Rights Agent"). The Company has agreed
that, from and after the Distribution Date, the Company will reserve 350,000
Preferred Shares initially for issuance upon exercise of the Rights.

              Until the earlier to occur of (i) the 10th day after a public
announcement that any person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 15% or more of the Common Shares or (ii) the 10th day after the
commencement or announcement of an intention to make a tender offer or exchange
offer the consummation of which would result in the beneficial ownership by a
person or group of 15% or more of the Common Shares (the earlier of (i) and (ii)
being called the "Distribution Date," whether or not either such date occurs
prior to the Record Date), the Rights will be evidenced, with respect to any of
the Common Share certificates outstanding as of the Record Date, by such Common
Share certificate. Notwithstanding the foregoing, if any person or group owns
15% or more of the Company's common stock as of June 11, 1996, then the Rights
would become exercisable with respect to such person or group only after such
person or group acquires beneficial ownership of any additional shares of the
Company's common stock.

              The Rights Agreement provides that, until the Distribution Date,
the Rights will be transferred with and only with the Common Shares. Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the close of business on the Record Date
upon transfer or new issuance of the Common Shares will contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier redemption, exchange, termination or expiration of the Rights), the
surrender for transfer of any certificates for Common Shares will also
constitute the transfer of the Rights associated with the Common Shares
represented by such certificate. As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Common Shares as of
the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.



                                        2                          Page 2 of 52
<PAGE>   3
              The Rights are not exercisable until the Distribution Date. The
Rights will expire on June 11, 2006, subject to the Company's right to extend
such date (the "Final Expiration Date"), unless earlier redeemed or exchanged by
the Company or terminated.

              Each Preferred Share purchasable upon exercise of the Rights will
be entitled to a minimum preferential quarterly dividend payment of $1.00 per
share but will be entitled to an aggregate dividend of 100 times the dividend,
if any, declared per Common Share. In the event of liquidation, the holders of
the Preferred Shares will be entitled to a minimum preferential liquidation
payment of $100.00 per share but will be entitled to an aggregate payment of 100
times the payment made per Common Share. Each Preferred Share will have 100
votes and will vote together with the Common Shares. Finally, in the event of
any merger, consolidation or other transaction in which Common Shares are
exchanged, each Preferred Share will be entitled to receive 100 times the amount
received per Common Share. These rights are protected by customary antidilution
provisions. Because of the nature of the Preferred Share's dividend, liquidation
and voting rights, the value of one one-hundredth of a Preferred Share
purchasable upon exercise of each Right should approximate the value of one
Common Share.

              The Purchase Price payable, and the number of Preferred Shares or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or warrants to subscribe for or purchase Preferred Shares or convertible
securities at less than the current market price of the Preferred Shares or
(iii) upon the distribution to holders of the Preferred Shares of evidences of
indebtedness, cash, securities or assets (excluding regular periodic cash
dividends at a rate not in excess of 125% of the rate of the last regular
periodic cash dividend theretofore paid or, in case regular periodic cash
dividends have not theretofore been paid, at a rate not in excess of 50% of the
average net income per share of the Company for the four quarters ended
immediately prior to the payment of such dividend, or dividends payable in
Preferred Shares (which dividends will be subject to the adjustment described in
clause (i) above)) or of subscription rights or warrants (other than those
referred to above).

              In the event that a person becomes an Acquiring Person (except
pursuant to certain cash offers for all outstanding Common Shares approved by
the Board) or if the Company were the surviving corporation in a merger with an
Acquiring Person or any affiliate or associate of an Acquiring Person and the
Common Shares were not changed or exchanged, each holder of a Right, other than
Rights that are or were acquired or beneficially owned by the 15% stockholder
(which Rights will thereafter be void), will thereafter have the right to
receive upon exercise that number of Common Shares having a market value of two
times the then current Purchase Price of the Right. With certain exceptions, in
the event that the Company were acquired in a merger or other business
combination transaction or more than 50% of its assets or earning power were
sold, proper provision shall be made so that each holder of a Right shall
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction would have a market
value of two times the then current Purchase Price of the Right.


                                        3                          Page 3 of 52
<PAGE>   4
              At any time after a person becomes an Acquiring Person (except
pursuant to certain cash offers for all outstanding Common Shares approved by
the Board) and prior to the acquisition by such Acquiring Person of 50% or more
of the outstanding Common Shares, the Board of Directors may cause the Company
to acquire the Rights (other than Rights owned by an Acquiring Person which have
become void), in whole or in part, in exchange for that number of Common Shares
having an aggregate value equal to the Spread (the excess of the value of the
Common Shares issuable upon exercise of a Right after a person becomes an
Acquiring Person over the Purchase Price) per Right (subject to adjustment).

              The Rights may be redeemed in whole, but not in part, at a price
of $.01 per Right (the "Redemption Price") by the Board of Directors at any time
prior to the close of business on the tenth day following the first date that a
person has become an Acquiring Person (except pursuant to certain cash offers
for all outstanding Common Shares approved by the Board). The redemption of the
Rights by the Board of Directors may be made effective at such time, on such
basis and with such conditions as the Board of Directors in its sole discretion
may establish. The Company may, at its option, pay the Redemption Price in cash,
Common Shares (based on the current per share market price at the time of the
redemption) or any other form of consideration deemed appropriate by the Board
of Directors. Immediately upon the action of the Board of Directors of the
Company electing to redeem the Rights, the Company shall make an announcement
thereof, and upon such election, the right to exercise the Rights will terminate
and the only right of the holders of Rights will be to receive the Redemption
Price.

              Until a Right is exercised, the holder thereof, as such, will have
no rights as a stockholder of the Company beyond those as an existing
stockholder, including, without limitation, the right to vote or to receive
dividends.

              Any of the provisions of the Rights Agreement may be amended by
the Board of Directors of the Company prior to the Distribution Date. After the
Distribution Date, the Company and the Rights Agent may amend or supplement the
Rights Agreement without the approval of any holders of Right Certificates to
cure any ambiguity, to correct or supplement any provision contained therein
which may be defective or inconsistent with any other provisions therein, to
shorten or lengthen any time period under the Rights Agreement (so long as,
under certain circumstances, a majority of Continuing Directors approve such
shortening or lengthening) or so long as the interests of the holders of Right
Certificates (other than an Acquiring Person or an affiliate or associate of an
Acquiring Person) are not adversely affected thereby, to make any other
provisions in regard to matters or questions arising thereunder which the
Company and the Rights Agent may deem necessary or desirable, including but not
limited to extending the Final Expiration Date. The Company may at any time
prior to such time as any person becomes an Acquiring Person amend the Rights
Agreement to lower the thresholds described above to not less than the greater
of (i) any percentage greater than the largest percentage of the outstanding
Common Shares then known by the Company to be beneficially owned by any person
or group of affiliated or associated persons and (ii) 10%.

              The term "Continuing Directors" means any member of the Board of
Directors of the Company who was a member of the Board prior to the time that
any Person becomes an 


                                         4                         Page 4 of 52

Acquiring Person, and any person who is subsequently elected to the Board if
such person is recommended or approved by a majority of the Continuing
Directors. Continuing Directors do not include an Acquiring Person, or an
affiliate or associate of an Acquiring Person, or any representative of the
foregoing.

              The Rights will cause substantial dilution to a person or group
that acquires 15% or more of the Company's stock on terms not approved by the
Company's Board of Directors. The Rights should not interfere with any merger or
other business combination approved by the Board of Directors at any time prior
to the first date that a person or group has become an Acquiring Person.

              The Rights Agreement specifying the terms of the Rights and the
text of the press release announcing the declaration of the Rights are
incorporated herein by reference as exhibits to this Current Report. The
foregoing description of the Rights is qualified in its entirety by reference to

                                RIGHTS AGREEMENT

     Agreement, dated as of June 11, 1996, between TEGAL CORPORATION, a Delaware
corporation (the "Company"), and CHASEMELLON SHAREHOLDER SERVICES, L.L.C., a New
Jersey limited liability company, as Rights Agent (the "Rights Agent").

                                    RECITALS

     The Board of Directors of the Company has authorized and declared a
dividend of one right (a "Right") for each Common Share (as defined in Section
1.6) of the Company outstanding at the close of business on July 1, 1996 (the
"Record Date") and has authorized the issuance of one Right (subject to
adjustment as provided herein) with respect to each Common Share that shall
become outstanding between the Record Date and the earliest of the Distribution
Date, the Redemption Date and the Final Expiration Date (as such terms are
defined in Sections 3.1 and 7.1), each Right initially representing the right to
purchase one one-hundredth of a share of Series A Junior Participating Preferred
Stock (the "Preferred Shares") of the Company having the rights, powers and
preferences set forth in the form of Certificate of Designations attached hereto
as Exhibit A, upon the terms and subject to the conditions hereinafter set
forth.

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

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

     1.1   "Acquiring Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates and Associates (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is hereinafter defined) of 15% or more of the Common Shares of the
Company then outstanding but shall not include the Company, any Subsidiary of
the Company or any employee benefit plan of the Company or of any Subsidiary of
the Company or any entity holding shares of capital stock of the Company for or
pursuant to the terms of any such plan, in its capacity as an agent or trustee
for any such plan.  Notwithstanding the foregoing, no Person shall become an
"Acquiring Person" as the result of an acquisition of Common Shares by the
Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such Person to 15% or more
of the Common Shares of the Company then outstanding; PROVIDED, HOWEVER, that if
a Person shall become the Beneficial Owner of 15% or more of the Common Shares
of the Company then outstanding solely by reason of share purchases by the
Company and shall, after such share purchases by the Company, become the
Beneficial Owner of any additional Common Shares of the Company, then such
Person shall be deemed to be an "Acquiring Person."  Notwithstanding the
foregoing, if the Board of Directors of the Company determines in good faith
that a Person who would otherwise be an "Acquiring Person," as defined pursuant
to the foregoing provisions of this Section 1.1, has become such inadvertently,
and such Person divests as promptly as practicable a sufficient number of Common
Shares so that such Person would no longer be an Acquiring Person, as defined
pursuant to the foregoing provisions of this Section 1.1, then such Person shall
not be deemed to be an "Acquiring Person" at any time for any purposes of this
Agreement.

     Notwithstanding anything in this definition of "Acquiring Person" to the
contrary, if, at the time of the adoption of this Agreement, any Person together
with any of his Affiliates or Associates is the Beneficial Owner of 15% or more
of the shares of Common Stock then outstanding, such Person shall not become an
Acquiring Person unless and until such time as (i) such Person or Affiliate or
Associate of such Person shall purchase or otherwise become the Beneficial Owner
of any additional shares of Common Stock





                                       1
<PAGE>   3
(less any shares referred to in clause (ii)) or (ii) any other Person or
Persons who is or are the Beneficial Owner of an aggregate of any additional
shares of Common Stock (less any shares referred to in clause (i)) shall become
an Affiliate or Associate of such Person and as a result of either clause (i)
or (ii), such Person shall together with any of his Affiliates or Associates is
the Beneficial Owner of 15% or more of the shares of Common Stock then
outstanding.

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

     1.3    A Person shall be deemed the "Beneficial Owner" of and shall be
deemed to "beneficially own" any securities:

          (i)  which such Person or any of such Person's Affiliates or
     Associates beneficially owns, directly or indirectly (as determined
     pursuant to Rule 13d-3 of the General Rules and Regulations under the
     Exchange Act as in effect on the date of this Agreement);

          (ii)  which such Person or any of such Person's Affiliates or
     Associates, directly or indirectly, has (A) the right to acquire (whether
     such right is exercisable immediately, or only after the passage of time,
     compliance with regulatory requirements, fulfillment of a condition or
     otherwise) pursuant to any agreement, arrangement or understanding, whether
     or not in writing (other than customary agreements with and between
     underwriters and selling group members with respect to a bona fide public
     offering of securities), or upon the exercise of conversion rights,
     exchange rights, rights (other than the Rights), warrants or options, or
     otherwise; PROVIDED, HOWEVER, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, (1) securities tendered
     pursuant to a tender or exchange offer made by or on behalf of such Person
     or any of such Person's Affiliates or Associates until such tendered
     securities are accepted for purchase or exchange or (2) securities which
     such Person or any of such Person's Affiliates or Associates may acquire,
     does or do acquire or may be deemed to have the right to acquire, pursuant
     to any merger or other acquisition agreement between the Company and such
     Person (or one or more of his Affiliates or Associates) if such agreement
     has been approved by the Board of Directors of the Company prior to such
     Person's becoming an Acquiring Person; or (B) the right to vote 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 clause (B) if the
     agreement, arrangement or understanding to vote such security (1) arises
     solely from a revocable proxy or consent given to such Person in response
     to a public proxy or consent solicitation made pursuant to, and in
     accordance with, the applicable rules and regulations of the Exchange Act
     and (2) is not also then reportable on Schedule 13D under the Exchange Act
     (or any comparable or successor report); or

          (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 (other than customary agreements with and
     between underwriters and selling group members with respect to a bona fide
     public offering of securities), whether or not in writing, for the purpose
     of acquiring, holding, voting (except pursuant to a revocable proxy as
     described in the proviso to Section 1.3(ii)(B)) or disposing of any
     securities of the Company.

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

     1.5   "close of business" on any given date shall mean 5:00 p.m., Pacific
time, on such date; PROVIDED, HOWEVER, that if such date is not a Business Day

     1.6   "Common Shares" when used with reference to the Company shall mean

Shares" when used with reference to any Person other than the Company shall
mean the capital stock with the greatest voting power, or the equity securities
or other equity interest having power to control or direct the management, of
such other Person or, if such Person is a Subsidiary of another Person, the
Person or Persons which ultimately control such first-mentioned Person, and
which has issued and outstanding such capital stock, equity securities or
equity interest.

     1.7   "Continuing Director" shall mean (i) any member of the Board of
Directors of the Company, while such Person is a member of the Board, who is
not an Acquiring Person, or an Affiliate or Associate of an Acquiring Person,
or an employee, director, representative, nominee or designee of any Acquiring
Person or of any such Affiliate or Associate, and was a member of the Board
prior to the time that any Person becomes an Acquiring Person or (ii) any
Person (during such period in which such Person is a member of the Board) who,
after the time that any Person becomes an Acquiring Person, becomes a member of
the Board and who is not an Acquiring Person, or an Affiliate or Associate of
an Acquiring Person, or an employee, director, representative, nominee or
designee of an Acquiring Person or of any such Affiliate or Associate, if such

approved by a majority of the Continuing Directors.

     1.8    "Person" shall mean any individual, partnership, joint venture,

such entity.

     1.10   "Subsidiary" of any Person shall mean any corporation or other
entity of which a majority of the voting power of the voting equity securities
or equity interests is owned, of record or beneficially, directly or indirectly,
by such Person.

     1.11   A "Trigger Event" shall be deemed to have occurred upon any Person
becoming an Acquiring Person.  Notwithstanding the foregoing, a Trigger Event
shall not be deemed to have occurred if the event causing the 15% ownership
threshold to be crossed is an acquisition of Common Shares made pursuant to a
cash tender offer made pursuant to the rules and regulations under the Exchange
Act and filed with the Securities and Exchange Commission on Schedule 14D-1 (or
any successor form) for all outstanding Common Shares not beneficially owned by
the Person making such offer (or by its Affiliates or Associates) so long as the
Board of Directors of the Company determines, after receiving advice from one or
more investment banking firms, that such offer is (i) at a price and on terms
which are fair to stockholders (taking into account all factors which such
members of the Board 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





                                       3

realize maximum value) and (ii) otherwise in the best interests of the Company
and its stockholders; PROVIDED, HOWEVER, that there must be Continuing
Directors then in office and any such determination shall require the
concurrence of a majority of such Continuing Directors.

     1.12   The following terms shall have the meanings defined for such terms
in the Sections set forth below:

     Section 2.  Appointment of Rights Agent.  The Company hereby appoints the
Rights Agent to act as agent for the Company and the holders of the Rights (who,
in accordance with Section 3, shall prior to the Distribution Date also be the
holders of the Common Shares) in accordance with the terms and conditions
hereof, and the Rights Agent hereby accepts such appointment.  The Company may
from time to time appoint such co-Rights Agents as it may deem necessary or
desirable.  In the event the Company appoints one or more co-Rights Agents, the
respective duties of the Rights Agent and any co-Rights Agent shall be as the
Company shall determine.  Contemporaneously with such appointment, if any, the
Company shall notify the Rights Agent thereof.

     Section 3.  Issuance of Right Certificates.

     3.1      Rights Evidenced by Share Certificates.  Until the earlier of (i)
the tenth day after the Shares Acquisition Date or (ii) the tenth day after the
date of the commencement of, or first public announcement of the intent of any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
holding shares of capital stock of the Company for or pursuant to the terms of
any such plan, in its capacity as an agent or





                                       4
<PAGE>   6
trustee for any such plan) to commence, a tender or exchange offer the
consummation of which would result in any Person becoming the Beneficial Owner
of Common Shares aggregating 15% or more of the then outstanding Common Shares
of the Company (the earlier of (i) and (ii) being herein referred to as the
"Distribution Date," whether or not either such date occurs prior to the Record
Date), (x) the Rights (unless earlier expired, redeemed or terminated) will be
evidenced (subject to the provisions of Section 3.2) by the certificates for
Common Shares registered in the names of the holders thereof (which
certificates for Common Shares shall also be deemed to be Right Certificates)
and not by separate certificates, and (y) the Rights (and the right to receive
certificates therefor) will be transferable only in connection with the
transfer of the underlying Common Shares.  The preceding sentence
notwithstanding, prior to the Distribution Date specified therein (or such
later Distribution Date as the Board of Directors of the Company may select
pursuant to this sentence), the Board of Directors of the Company may postpone,
one or more times, the Distribution Date beyond the earlier of the dates set
forth in such preceding sentence; PROVIDED, HOWEVER, that there must be
Continuing Directors then in office and any such postponement shall require the
approval of at least a majority of such Continuing Directors.  As soon as
practicable after the Distribution Date, the Rights Agent will send, by
first-class, postage-prepaid mail, to each record holder of Common Shares as of
the close of business on the Distribution Date, at the address of such holder
shown on the records of the Company, one or more certificates for Rights, in
substantially the form of Exhibit B hereto (a "Right Certificate"), evidencing
one Right (subject to adjustment as provided herein) for each Common Share so
held.  As of the Distribution Date, the Rights will be evidenced solely by such
Right Certificates.

     3.2      Summary of Rights.  On the Record Date or as soon as practicable
thereafter, the Company will send or cause to be sent a copy of a Summary of
Rights to Purchase Preferred Shares, in substantially the form attached hereto
as Exhibit C (the "Summary of Rights"), by first-class, postage-prepaid mail, to
each record holder of Common Shares as of the close of business on the Record
Date at the address of such holder shown on the records of the Company.  With
respect to certificates for Common Shares outstanding as of the close of
business on the Record Date, until the Distribution Date (or the earlier
Redemption Date or Final Expiration Date), the Rights will be evidenced by such
certificates for Common Shares registered in the names of the holders thereof
together with a copy of the Summary of Rights and the registered holders of the
Common Shares shall also be registered holders of the associated Rights.  Until
the Distribution Date (or the earlier Redemption Date or Final Expiration Date),
the surrender for transfer of any certificate for Common Shares outstanding at
the close of business on the Record Date, with or without a copy of the Summary
of Rights, shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

     3.3      New Certificates After Record Date.  Certificates for Common
Shares which become outstanding (whether upon issuance out of authorized but
unissued Common Shares, issuance out of treasury or transfer or exchange of
outstanding Common Shares) after the Record Date but prior to the earliest of
the Distribution Date, the Redemption Date or the Final Expiration Date, shall
be deemed also to be certificates for Rights, and shall have impressed, printed,
stamped, written or otherwise affixed onto them the following legend:

         This certificate also evidences and entitles the holder hereof to
         certain Rights as set forth in a Rights Agreement between Tegal
         Corporation and ChaseMellon Shareholder Services, L.L.C., dated as of
         June 11, 1996, as the same may be amended from time to time (the
         "Rights Agreement"), the terms of which are hereby incorporated herein
         by reference and a copy of which is on file at the principal executive
         offices of Tegal Corporation.  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.  Tegal Corporation will mail to the holder of this
         certificate a copy of the Rights Agreement without charge after



                                       5
<PAGE>   7
         receipt of a written request therefor.  AS DESCRIBED IN THE RIGHTS
         AGREEMENT, RIGHTS WHICH ARE HELD BY OR HAVE BEEN HELD BY ACQUIRING
         PERSONS OR ASSOCIATES OR AFFILIATES THEREOF (AS DEFINED IN THE RIGHTS
         AGREEMENT) SHALL BECOME NULL AND VOID.

With respect to such certificates containing the foregoing legend, until the
Distribution Date (or the earlier Redemption Date or Final Expiration Date),
the Rights associated with the Common Shares represented by such certificates
shall be evidenced by such certificates (together with a copy of the Summary of
Rights), and the surrender for transfer of any such certificates shall also
constitute the transfer of the Rights associated with the Common Shares
represented thereby.  In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed cancelled and retired
so that the Company shall not be entitled to exercise any Rights associated
with the Common Shares which are no longer outstanding.

     Section 4.  Form of Right Certificates.  The Right Certificates (and the
forms of election to purchase Preferred Shares, certification and assignment to
be printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Rights
Agreement, or as may be required to comply with any applicable law or with any
rule or regulation made pursuant thereto or with any rule or regulation of any
stock exchange or trading system on which the Rights may from time to time be
listed or quoted, or to conform to usage. Subject to the terms and conditions
hereof, the Right Certificates, whenever issued, shall be dated as of the Record
Date, and shall show the date of countersignature by the Rights Agent, and on
their face shall entitle the holders thereof to purchase such number of one
one-hundredths of a Preferred Share as shall be set forth therein at the price
per one one-hundredth of a Preferred Share set forth therein (the "Purchase
Price"), but the number of such one one-hundredths of a Preferred Share and the
Purchase Price shall be subject to adjustment as provided herein.

     Section 5.  Countersignature and Registration. The Right Certificates shall
be executed on behalf of the Company by its Chairman of the Board of Directors,
the Chief Executive Officer, 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 by the Secretary or any Assistant
Secretary of the Company, either manually or by facsimile signature.  The Right
Certificates shall be manually countersigned by an authorized signatory of the
Rights Agent, but it shall not be necessary for the same signatory to
countersign all of the Right Certificates hereunder.  No Right Certificate shall
be valid for any purpose unless so countersigned.  In case any officer of the
Company who shall have signed any of the Right Certificates shall cease to be
such officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right Certificates, nevertheless, may
be countersigned by the Rights Agent, and issued and delivered by the Company
with the same force and effect as though the person who signed such Right
Certificates had not ceased to be such officer of the Company; and any Right
Certificate may be signed on behalf of the Company by any person who, at the
actual date of the execution of such Right Certificate, shall be a proper
officer of the Company to sign such Right Certificate, although at the date of
the execution of this Rights Agreement any such person was not such an officer.

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

     Section 6.  Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. Subject
to the provisions of Section 11.1.2 and Section 14, at any time after the close
of business on the Distribution Date, and at or prior to the close of business
on the earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11.1.2 or that have been
exchanged pursuant to Section 27) may be transferred, split up or combined or
exchanged for another Right Certificate or Right Certificates, entitling the
registered holder to purchase a like number of one one-hundredths of a Preferred
Share as the Right Certificate or Right Certificates surrendered then entitled
such holder to purchase.  Any registered holder desiring to transfer, split up
or combine or exchange any Right Certificate shall make such request in writing
delivered to the Rights Agent, and shall surrender, together with any required
form of assignment and certificate duly completed, the Right Certificate or
Right Certificates to be transferred, split up or combined or exchanged at the
office of the Rights Agent designated for such purpose. Neither the Rights Agent
nor the Company shall be obligated to take any action whatsoever with respect to
the transfer of any such surrendered Right Certificate or Right Certificates
until the registered holder shall have completed and signed the certificate
contained in the form of assignment on the reverse side of such Right
Certificate or Right Certificates 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 countersign and deliver to the person entitled
thereto a Right Certificate or Right Certificates, as the case may be, as so
requested.  The Company may require payment from the holders of Right
Certificates of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer, split up or combination or
exchange of such Right Certificates.

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

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

     7.1      Exercise of Rights.  Subject to Section 11.1.3 and except as
otherwise provided herein, the registered holder of any Right Certificate may
exercise the Rights evidenced thereby in whole or in part at any time after the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase and certification on the reverse side thereof duly
executed, to the Rights Agent at the office of the Rights Agent designated for
such purpose, together with payment of the Purchase Price for each one
one-hundredth of a Preferred Share as to which the Rights are exercised, at or
prior to the earliest of (i) the close of business on June 11, 2006 (the "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 (the "Redemption Date"), (iii) the closing of any merger or other
acquisition transaction involving the Company pursuant to an agreement of the
type described in Section 1.3(ii)(A)(2), at which time the Rights are deemed
terminated, or (iv) the time at which the Rights are exchanged as provided in
Section 27.

     7.2      Purchase Price.  The Purchase Price for each one one-hundredth of
a Preferred Share pursuant to the exercise of a Right shall initially be $45.00,
shall be subject to adjustment from time to time as provided in Sections 11, 13
and 26 and shall be payable in lawful money of the United States of America in
accordance with paragraph 7.3.





                                       7
<PAGE>   9
     7.3      Payment Procedures.  Upon receipt of a Right Certificate
representing exercisable Rights, with the form of election to purchase and
certification duly executed, accompanied by payment of the Purchase Price for
the shares to be purchased and an amount equal to any applicable transfer tax
required to be paid by the holder of such Right Certificate in accordance with
Section 9, by certified or cashier's check or money order payable to the order
of the Company, the Rights Agent shall thereupon promptly (i)(A) requisition
from any transfer agent of the Preferred Shares (or make available, if the
Rights Agent is the transfer agent) certificates for the number of Preferred
Shares 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 Preferred Shares issuable upon
exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing such number of one
one-hundredths of a Preferred Share as are to be purchased (in which case
certificates for the Preferred Shares represented by such receipts shall be
deposited by the transfer agent with the depositary agent) and the Company
hereby directs the depositary agent to comply with all such requests, (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of the issuance of fractional shares in accordance with Section 14, (iii)
promptly after receipt of such certificates or depositary receipts, cause the
same to be delivered to or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be designated by such
holder and (iv) when appropriate, after receipt, promptly deliver such cash to
or upon the order of the registered holder of such Right Certificate.  In the
event that the Company is obligated to issue other securities of the Company,
pay cash and/or distribute other property pursuant to Section 11.1.3, 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.

     7.4      Partial Exercise.  In case the registered holder of any Right
Certificate shall exercise less than all the Rights evidenced thereby, a new
Right Certificate evidencing Rights equivalent to the Rights remaining
unexercised shall be issued by the Rights Agent and delivered to the registered
holder of such Right Certificate or to his duly authorized assigns, subject to
the provisions of Section 14.

     7.5      Full Information Concerning Ownership. Notwithstanding anything in
this Rights Agreement to the contrary, neither the Rights Agent nor the Company
shall be obligated to undertake any action with respect to a registered holder
of Rights upon the occurrence of any purported exercise as set forth in this
Section 7 unless the certificate contained in the form of election to purchase
set forth on the reverse side of the Right Certificate surrendered for such
exercise shall have been duly completed and signed by the registered holder
thereof and the Company shall have been provided with 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 Right Certificates.  All Right
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Rights Agreement.  The Company shall deliver to
the Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof.  The Rights Agent shall
deliver all cancelled Right Certificates to the Company, or shall, at the
written request of the Company, destroy such cancelled Right Certificates, and
in such case shall deliver a certificate of destruction thereof to the Company.

     Section 9.  Reservation and Availability of Capital Stock. The Company
covenants and agrees that from and after the Distribution Date it will cause to
be reserved and kept available out of its authorized and unissued Preferred
Shares (and, following the occurrence of a Trigger Event, out of its authorized





                                       8
<PAGE>   10
and unissued Common Shares or other securities or out of its shares held in its
treasury) the number of Preferred Shares (and, following the occurrence of a
Trigger Event, Common Shares and/or other securities) that will be sufficient
to permit the exercise in full of all outstanding Rights.

     So long as the Preferred Shares (and, following the occurrence of a Trigger
Event, Common Shares and/or other securities) issuable upon the exercise of
Rights may be listed on any national securities exchange or traded in the
over-the-counter market and quoted on the National Association of Securities
Dealers, Inc. Automated Quotation System ("Nasdaq"), 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 so traded in such over-the-counter market, upon official notice of issuance
upon such exercise.

     The Company covenants and agrees that it will take all such action as may
be necessary to ensure that all Preferred Shares (and, following the occurrence
of a Trigger Event, Common Shares  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 shares.

     The Company further covenants and agrees that it will pay when due and
payable any and all Federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares (or Common Shares 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 Right Certificates to a person other than, or the issuance or delivery of
certificates for the Preferred Shares (or Common Shares and/or other securities,
as the case may be) in a name other than that of, the registered holder of the
Right Certificate evidencing Rights surrendered for exercise or to issue or
deliver any certificates for Preferred Shares (or Common Shares 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 any such tax shall have been paid
(any such tax being payable by the holder of such Right Certificate at the time
of surrender) or until it has been established to the Company's satisfaction
that no such tax is due.

     Section 10.  Preferred Shares Record Date.  Each person in whose name any
certificate for Preferred Shares (or Common Shares 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 the Preferred Shares (or Common
Shares and/or other securities, as the case may be) represented thereby on, and
such certificate shall be dated, the date upon which the Right Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer taxes) was made; PROVIDED, HOWEVER, that if the
date of such surrender and payment is a date upon which the Preferred Shares (or
Common Shares 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 Shares (or Common
Shares and/or other securities, as the case may be) transfer books of the
Company are open.

     Section 11.  Adjustment of Purchase Price, Number of Shares or Number of
Rights.  The Purchase Price, the number 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.

     11.1  Post Execution Events.

     11.1.1  Corporate Dividends, Reclassifications, Etc.  In the event the
Company shall at any time after the date of this Rights Agreement (A) declare a
dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the
outstanding Preferred Shares, (C) combine the outstanding Preferred Shares into
a smaller number of shares or (D) issue any shares of its capital stock in a
reclassification of the Preferred Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), except as otherwise provided in this Section 11.1,
the Purchase Price in effect at the time of the record date for such dividend or
of the effective date of such subdivision, combination or reclassification, and
the number and kind of shares of capital stock issuable on such date, shall be
proportionately adjusted so that the holder of any Right exercised after such
time shall be entitled to receive the aggregate number and kind of shares of
capital stock which, if such Right had been exercised immediately prior to such
date and at a time when the Preferred Shares transfer books of the Company were
open, he would have owned upon such exercise and been entitled to receive by
virtue of such dividend, subdivision, combination or reclassification.  If an
event occurs which would require an adjustment under both Section 11.1.1 and
Section 11.1.2, the adjustment provided for in this Section 11.1.1 shall be in
addition to, and shall be made prior to, the adjustment required pursuant to,
Section 11.1.2.

     11.1.2  Acquiring Person Events; Triggering Events.  Subject to Sections
23.1 and 27 of this Agreement, in the event

          (A)  any Acquiring Person or any Associate or Affiliate of any
     Acquiring Person, at any time after the date of this Rights 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 Shares of the
     Company shall remain outstanding and not changed into or exchanged for
     stock or other securities of any other Person or the Company or cash or any
     other property, or

          (B)  that a Trigger Event occurs,

then, from and after the first occurrence of such event, each holder of a
Right, except as provided below, shall thereafter have a right to receive, upon
exercise thereof at a price per Right equal to the then current Purchase Price
multiplied by the number of one one-hundredths of a Preferred Share for which a
Right is then exercisable (without giving effect to this Section 11.1.2), in
accordance with the terms of this Rights Agreement, such number of Common
Shares as shall equal the result obtained by (x) multiplying the then current
Purchase Price by the then number of one one-hundredths of a Preferred Share
for which a Right is then exercisable (without giving effect to this Section
11.1.2) and (y) dividing that product by 50% of the current per share market
price of the Common Shares (determined pursuant to Section 11.4) on the first
of the date of the occurrence of, or the date of the first public announcement
of, one of the events listed above in this Section 11.1.2 (the "Adjustment
Shares"); PROVIDED, HOWEVER, that if the transaction that would otherwise give
rise to the foregoing adjustment is also subject to the provisions of Section
13, then only the provisions of Section 13 shall apply and no adjustment shall
be made pursuant to this Section 11.1.2; PROVIDED, FURTHER, that nothing
contained in this Section 11.1.2 shall limit or otherwise diminish the power of
the Board of Directors (or, if applicable, the Continuing Directors) to
postpone the Distribution Date pursuant to Section 3.1 or to extend the period
during which the Rights may be redeemed pursuant to Section 23.1; PROVIDED,
FURTHER, that the Purchase Price and the number of Adjustment Shares shall
thereafter be subject to further adjustment pursuant to Section 11.1.1 hereof.
Notwithstanding the foregoing, upon the occurrence of either of the events
listed above in this Section 11.1.2, any Rights that are or were acquired or
beneficially owned by (1) an Acquiring Person or any Associate or Affiliate
thereof, (2) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person becomes such, or
(3) a transferee of an Acquiring Person (or of any such Associate or Affiliate)
who becomes a transferee prior





                                       10
<PAGE>   12
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 the Acquiring Person has any continuing
agreement, arrangement or understanding regarding the transferred Rights or (B)
a transfer which the Board of Directors of the Company has determined is part
of a plan, arrangement or understanding which has as a primary purpose or
effect avoidance of this Section 11.1.2, shall become void, and any holder
(whether or not such holder is an Acquiring Person or an Associate or Affiliate
of an Acquiring Person) of such Rights shall thereafter have no right to
exercise such Rights under any provision of this Rights Agreement or otherwise.
The Company shall not enter into any transaction of the type described in this
Section 11.1.2 if at the time of such transaction there are any rights,
warrants, instruments or securities outstanding or any arrangements which, as a
result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights.  Any
Right Certificate issued pursuant to Section 3 or Section 22 that represents
Rights beneficially owned by: (1) an Acquiring Person or any Associate or
Affiliate thereof, (2) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes such, or (3) 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 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 the Board of Directors
of the Company has determined is part of a plan, arrangement or understanding
which has as a primary purpose or effect avoidance of this Section 11.1.2, and
any Right Certificate issued pursuant to Section 6, 7.4 or 22 or this Section
11 upon transfer, exchange, replacement or adjustment of any other Right
Certificate referred to in this sentence, shall contain the following legend
(PROVIDED, HOWEVER, that the Rights Agent shall not be responsible for affixing
such legend unless it has actual knowledge as to the foregoing circumstances or
the Company has notified the Rights Agent in writing thereof):

               THE RIGHTS REPRESENTED BY THIS RIGHT CERTIFICATE ARE HELD OR HAVE
               BEEN HELD BY A PERSON WHO IS OR WAS AN ACQUIRING PERSON OR AN
               AFFILIATE OR AN ASSOCIATE OF AN ACQUIRING PERSON OR A NOMINEE
               THEREOF. THIS RIGHT CERTIFICATE AND THE RIGHTS REPRESENTED HEREBY
               HAVE BECOME NULL AND VOID AS SPECIFIED IN SECTION 11.1.2 OF THE
               RIGHTS AGREEMENT.

     The Company shall use all reasonable efforts to insure that the provisions
of this Section 11.1.2 are complied with, but shall have no liability to any
holder of Right Certificates or other Person as a result of its failure to make
any determinations with respect to any Acquiring Person or its Affiliates,
Associates or transferees hereunder.

     11.1.3  Insufficient Shares.  In the event that upon the occurrence of one
or more of the events listed in Section 11.1.2 above there shall not be
sufficient Common Shares authorized but unissued, or held by the Company as
treasury shares, to permit the exercise in full of the Rights in accordance with
the foregoing Section 11.1.2, the Company shall take all such action as may be
necessary to authorize additional Common Shares for issuance upon exercise of
the Rights, PROVIDED, HOWEVER, that if the Company determines that it is unable
to cause the authorization of a sufficient number of additional Common Shares,
then, in the event the Rights become exercisable, the Company, with respect to
each Right and to the extent necessary and permitted by applicable law and any
agreements or instruments in effect on the date hereof to which it is a party,
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,
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 Shares or other equity securities of the Company (including, without
limitation, shares, or units of shares, of preferred stock which the Board





                                       11
<PAGE>   13
of Directors of the Company has deemed to have the same value as Common Shares)
(each such share of preferred stock constituting a "common stock equivalent")),
(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 of Directors of the Company
based upon the advice of a nationally recognized investment banking firm
selected by the Board of Directors of the Company; PROVIDED, HOWEVER, that if
the Company shall not have made adequate provision to deliver value pursuant to
clause (B) above within thirty (30) days following the first occurrence of one
of the events listed in Section 11.1.2 above, then the Company shall be
obligated to deliver, upon the surrender for exercise of a Right and without
requiring payment of the Purchase Price, Common Shares (to the extent
available) and then, if necessary, cash, which in the aggregate are equal to
the Spread.  If the Board of Directors of the Company shall determine in good
faith that it is unlikely that sufficient additional Common Shares could be
authorized for issuance upon exercise in full of the Rights, the thirty (30)
day period set forth above may be extended and re-extended to the extent
necessary, but not more than ninety (90) days following the first occurrence of
one of the events listed in Section 11.1.2 above, in order that the Company may
seek stockholder approval for the authorization of such additional shares (such
period as may be extended, 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 11.1.3, the Company (x) shall provide that
such action shall apply uniformly to all outstanding Rights, and (y) may
suspend the exercisability of the Rights until the expiration of the
Substitution Period in order to seek any authorization of additional shares
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 11.1.3, the value of a Common Share shall be the
current per share market price (as determined pursuant to Section 11.4) on the
date of the first occurrence of one of the events listed in Section 11.1.2
above and the value of any "common stock equivalent" shall be deemed to have
the same value as the Common Shares on such date.

     11.2  Dilutive Rights Offering.  In case the Company shall fix a record
date for the issuance of rights, options or warrants to all holders of Preferred
Shares entitling them (for a period expiring within 45 calendar days after such
record date) to subscribe for or purchase Preferred Shares (or securities having
the same rights, privileges and preferences as the Preferred Shares ("equivalent
preferred stock")) or securities convertible into Preferred Shares or equivalent
preferred stock at a price per share of Preferred Shares or per share of
equivalent preferred stock (or having a conversion or exercise price per share,
if a security convertible into or exercisable for Preferred Shares or equivalent
preferred stock) less than the current per share market price of the Preferred
Shares (as defined in Section 11.4) on such record date, the Purchase Price to
be in effect after such record date shall be determined by multiplying the
Purchase Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the number of Preferred Shares outstanding on
such record date plus the number of Preferred Shares which the aggregate
offering price of the total number of Preferred Shares and/or equivalent
preferred stock to be offered (and/or the aggregate initial conversion price of
the convertible securities so to be offered) would purchase at such current per
share market price and the denominator of which shall be the number of Preferred
Shares outstanding on such record date plus the number of additional Preferred
Shares 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 in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and the
holders of the Rights.  Preferred Shares owned by or held for the account of the
Company or any Subsidiary of the Company shall not be deemed outstanding for the
purpose of any such computation.  Such adjustments shall be made successively
whenever such a record date is fixed; and in





                                       12
<PAGE>   14
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.

     11.3  Distributions.  In case the Company shall fix a record date for the
making of a distribution to all holders of the Preferred Shares (including any
such distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of
indebtedness, cash, securities or assets (other than a regular periodic cash
dividend at a rate not in excess of 125% of the rate of the last regular
periodic cash dividend theretofore paid or, in case regular periodic cash
dividends have not theretofore been paid, at a rate not in excess of 50% of the
average net income per share of the Company for the four quarters ended
immediately prior to the payment of such dividend, or a dividend payable in
Preferred Shares (which dividend, for purposes of this Agreement, shall be
subject to the provisions of Section 11.1.1(A) hereof)) or convertible
securities, or subscription rights or warrants (excluding those referred to in
Section 11.2), 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 per
share market price of the Preferred Shares (as defined in Section 11.4) on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the cash, assets,
securities or evidences of indebtedness so to be distributed or of such
subscription rights or warrants applicable to one Preferred Share and the
denominator of which shall be such current per share market price of the
Preferred Shares.  Such adjustments shall be made successively whenever such a
record date is fixed; and in the event that such distribution is not so made,
the Purchase Price shall again be adjusted to be the Purchase Price which would
then be in effect if such record date had not been fixed.

     11.4  Current Per Share Market Value.

     11.4.1   General.  For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11.4.1) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days (as such term is hereinafter defined) immediately prior to such
date; PROVIDED, HOWEVER, that in the event that the current per share market
price of the Security is determined during any period following the announcement
by the issuer of such Security of (i) a dividend or distribution on such
Security payable in shares of such Security or securities convertible into such
shares or (ii) any subdivision, combination or reclassification of such
Security, and prior to the expiration of thirty (30) Trading Days after the
ex-dividend date for such dividend or distribution, or the record date for such
subdivision, combination or reclassification, then, and in each such case, the
"current per share market price" shall be appropriately adjusted to reflect the
current market price per share equivalent of such Security.  The closing price
for each day shall be the last sale price, regular way, 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 Security is not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Security is listed or
admitted to trading or, if the Security is not listed or admitted to trading on
any national securities exchange, the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported by Nasdaq or such other system then in use, or, if on any such date
the Security is not quoted by any such organization, the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Security selected by the Board of Directors of the Company.  If on any
such date no such market maker is making a market in the Security, the fair
value of the Security 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





                                       13
<PAGE>   15
on which the Security is listed or admitted to trading is open for the
transaction of business or, if the Security is not listed or admitted to
trading on any national securities exchange, a Business Day.  If the Security
is not publicly held or not so listed or traded, "current per share market
price" shall mean the fair value per share as determined in good faith by the
Board of Directors of the Company or, if at the time of such determination
there is an Acquiring Person, by a majority of the Continuing Directors then in
office, or if there are no Continuing Directors, by a nationally recognized
investment banking firm selected by the Board of Directors, which shall have
the duty to make such determination in a reasonable and objective manner, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

     11.4.2  Preferred Shares.  Notwithstanding Section 11.4.1, for the purpose
of any computation hereunder, the "current per share market price" of the
Preferred Shares shall be determined in the same manner as set forth above in
Section 11.4.1 (other than the last sentence thereof).  If the current per share
market price of the Preferred Shares cannot be determined in the manner
described in Section 11.4.1, the "current per share market price" of the
Preferred Shares 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 Shares occurring
after the date of this Agreement) multiplied by the current per share market
price of the Common Shares.  If neither the Common Shares nor the Preferred
Shares is publicly held or so listed or traded, "current per share market price"
of the Preferred Shares shall mean the fair value per share as determined in
good faith by the Board of Directors of the Company, or, if at the time of such
determination there is an Acquiring Person, by a majority of the Continuing
Directors then in office, or if there are no Continuing Directors, by a
nationally recognized investment banking firm selected by the Board of Directors
of the Company, which shall have the duty to make such determination in a
reasonable and objective manner, which determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes.
For purposes of this Agreement, the "current per share market price" of one
one-hundredth of a Preferred Share shall be equal to the "current per share
market price" of one Preferred Share divided by 100.

     11.5  Insignificant Changes.  No adjustment in the Purchase Price shall be
required unless such adjustment would require an increase or decrease of at
least 1% in such price.  Any adjustments which by reason of this Section 11.5
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment.  All calculations under this Section 11 shall be made
to the nearest cent or to the nearest one-millionth of a Preferred Share or the
nearest ten-thousandth of a Common Share, as the case may be.

     11.6  Shares Other Than Preferred Shares.  If as a result of an adjustment
made pursuant to Section 11.1, the holder of any Right thereafter exercised
shall become entitled to receive any shares of capital stock of the Company
other than Preferred Shares, thereafter the number of such other shares so
receivable upon exercise of any Right shall be subject to adjustment from time
to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Preferred Shares contained in Sections 11.1
through 11.3, inclusive, and the provisions of Sections 7, 9, 10 and 13 with
respect to the Preferred Shares shall apply on like terms to any such other
shares.

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





                                       14
<PAGE>   16
     11.8  Effect of Adjustments.  Unless the Company shall have exercised its
election as provided in Section 11.9, upon each adjustment of the Purchase Price
as a result of the calculations made in Sections 11.2 and 11.3, each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one- hundredths of a Preferred Share (calculated to the nearest
one-millionth of a Preferred Share) obtained by (i) multiplying (x) the number
of one one-hundredths of a Preferred 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.

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

     11.10  Right Certificates Unchanged.  Irrespective of any adjustment or
change in the Purchase Price or the number of one one- hundredths of a Preferred
Share issuable upon the exercise of the Rights, the Right Certificates
theretofore and thereafter issued may continue to express the Purchase Price per
share and the number of one one-hundredths of a Preferred Share which were
expressed in the initial Right Certificates issued hereunder.

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

     11.12  Deferred Issuance.  In any case in which this Section 11 shall
require that an adjustment in the Purchase Price be made effective as of a
record date for a specified event, the Company may elect to defer until the
occurrence of such event the issuing to the holder of any Right exercised after
such 


                                       15
<PAGE>   17

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

     11.13  Reduction in Purchase Price.  Anything in this Section 11 to the
contrary notwithstanding, the Company shall be entitled to make such reductions
in the Purchase Price, in addition to those adjustments expressly required by
this Section 11, as and to the extent that it in its sole discretion shall
determine to be advisable in order that any consolidation or subdivision of the
Preferred Shares, issuance wholly for cash of any of the Preferred Shares at
less than the current market price, issuance wholly for cash of Preferred Shares
or securities which by their terms are convertible into or exchangeable for
Preferred Shares, dividends on Preferred Shares payable in Preferred Shares or
issuance of rights, options or warrants referred to hereinabove in this Section
11, hereafter made by the Company to holders of its Preferred Shares shall not
be taxable to such stockholders.

     11.14  The Company covenants and agrees that after the Distribution Date it
will not, except as permitted by Section 23 or Section 26, 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 substantially diminish or otherwise
eliminate the benefits intended to be afforded by the Rights.

     11.15  Notwithstanding anything contained in this Agreement to the
contrary, in the event that the Company shall at any time after the date hereof
and prior to the Distribution Date (i) declare or pay any dividend on the
outstanding Common Shares payable in Common Shares, (ii) effect a subdivision or
consolidation of the outstanding Common Shares (by reclassification or otherwise
than by the payment of dividends payable in Common Shares), or (iii) combine the
outstanding Common Shares into a greater or lesser number of Common Shares, then
in any such case, the number of Rights associated with each Common Share 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 Common Share following any such event shall equal the
result obtained by multiplying the number of Rights associated with each Common
Share immediately prior to such event by a fraction, the numerator of which
shall be the total number of Common Shares outstanding immediately prior to the
occurrence of the event and the denominator of which shall be the total number
of Common Shares outstanding immediately following the occurrence of such event.
The adjustments provided for in this Section 11.15 shall be made successively
whenever such a dividend is declared or paid or such a subdivision, combination
or consolidation is effected.

     Section 12.  Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 and 13, 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 Common Shares or the
Preferred Shares a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Right Certificate in accordance with Section 25.  The Rights
Agent shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall not be deemed to have knowledge of any
such adjustment unless and until it shall have received such certificate.

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

     13.1  General.  In the event that, from and after the first occurrence of a
Trigger Event, directly or indirectly, (A) the Company shall consolidate with,
or merge with and into, any other Person and the Company shall not be the
continuing or surviving corporation, (B) any Person shall consolidate with the
Company, or merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of the Company or any other Person or cash or any
other property, or (C) the Company shall sell, exchange, mortgage or otherwise
transfer (or one or more of its Subsidiaries shall sell, exchange, mortgage or
otherwise transfer), in one or more transactions, assets or earning power
aggregating 50% or more of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person or Persons, then, and in
each such case, proper provision shall be made so that (i) each holder of a
Right (except as provided in Section 11.1.2 and as otherwise provided herein)
shall thereafter have the right to receive, upon the exercise thereof at a price
per Right equal to the then current Purchase Price multiplied by the number of
one one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to the first occurrence of a Trigger Event (as subsequently
adjusted pursuant to Sections 11.1.1, 11.2, 11.3, 11.8, 11.9 and 11.12), in
accordance with the terms of this Rights Agreement and in lieu of Preferred
Shares, such number of Common Shares of such other Person (including the Company
as successor thereto or as the surviving corporation) as shall be equal to the
result obtained by (x) multiplying the then current Purchase Price by the number
of one one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to the first occurrence of a Trigger Event (as subsequently
adjusted pursuant to Sections 11.1.1, 11.2, 11.3, 11.8, 11.9 and 11.12) and (y)
dividing that product by 50% of the then current per share market price of the
Common Shares of such other Person (determined pursuant to Section 11.4) on the
date of consummation of such consolidation, merger, sale or transfer; PROVIDED,
that the price per Right so payable and the number of Common Shares of such
Person so purchasable shall thereafter be adjusted in accordance with Sections
11.1.1, 11.2, 11.3, 11.8, 11.9 and 11.12 by reason of such subsequent events
covered thereby occurring in respect of such Person; (ii) the issuer of such
Common Shares shall thereafter be liable for, and shall assume, by virtue of
such consolidation, merger, sale or transfer, all the obligations and duties of
the Company pursuant to this Rights Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such issuer; and (iv) such issuer shall take
such steps (including, but not limited to, the reservation of a sufficient
number of its Common Shares in accordance with Section 9) in connection with
such consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to its
Common Shares thereafter deliverable upon the exercise of the Rights.  The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights.  The
Company shall not consummate any such consolidation, merger, sale or transfer
unless prior thereto the Company and such issuer shall have executed and
delivered to the Rights Agent a supplemental agreement so providing.  The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

     13.2  Approved Acquisitions.  Notwithstanding anything contained herein to
the contrary, in the event of any merger or other acquisition transaction
involving the Company pursuant to a merger or other acquisition agreement
between the Company and any Person (or one or more of such Person's Affiliates
or Associates) which agreement has been approved by the Board of Directors of
the Company prior to any Person becoming an Acquiring Person, this Rights
Agreement and the rights of holders of Rights hereunder shall be terminated in
accordance with Section 7.1.

     Section 14.  Fractional Rights and Fractional Shares.

     14.1  Cash in Lieu of Fractional Rights.  The Company shall not be required
to issue fractions of Rights or to distribute Right Certificates which evidence
fractional Rights.  In lieu of such fractional Rights, there shall be paid to
the registered holders of the Right Certificates with regard to which such
fractional Rights would otherwise be issuable an amount in cash equal to the
same fraction of the current market value of a whole Right.  For the purposes of
this Section 14.1, the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such fractional Rights would have been otherwise issuable.  The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the Rights are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Rights are listed or
admitted to trading or, if the Rights are not listed or admitted to trading on
any national securities exchange, the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the- counter
market, as reported by Nasdaq or such other system then in use or, if on any
such date the Rights are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Rights selected by the Board of Directors of the Company.  If on
any such date no such market maker is making a market in the Rights, the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

     14.2  Cash in Lieu of Fractional Shares.  The Company shall not be required
to issue fractions of Preferred Shares (other than fractions which are integral
multiples of one one-hundredth of a Preferred Share) upon exercise of the Rights
or to distribute certificates which evidence fractional Preferred Shares (other
than fractions which are integral multiples of one one-hundredth of a Preferred
Share).  Fractions of Preferred Shares in integral multiples of one
one-hundredth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, pursuant to an appropriate agreement between
the Company and a depositary selected by it; PROVIDED, that such agreement shall
provide that the holders of such depositary receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts.  In lieu of
fractional Preferred Shares that are not integral multiples of one one-hundredth
of a Preferred Share, the Company shall pay to the registered holders of Right
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current per share market price of one
Preferred Share.  For purposes of this Section 14.2, the current per share
market price of a Preferred Share shall be the closing price of a Preferred
Share (as determined pursuant to the second sentence of Section 11.4.2) for the
Trading Day immediately prior to the date of such exercise.

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

     Section 15.  Rights of Action.  All rights of action in respect of this
Rights Agreement, except the rights of action given to the Rights Agent under
Section 18, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in his own behalf and for his own
benefit, enforce this Rights





                                       18

<PAGE>   20
Agreement, and may institute and maintain any suit, action or proceeding
against the Company to enforce this Rights Agreement, or otherwise enforce or
act in respect of his right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this Rights
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 Rights
Agreement and shall be entitled to specific performance of the obligations
under, and injunctive relief against actual or threatened violations of, the
obligations of any Person (including, without limitation, the Company) subject
to this Rights Agreement.

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

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

          (b)  as of and after the Distribution Date, the Right Certificates
     are transferable only on the registry books of the Rights Agent if
     surrendered at the office of the Rights Agent designated for such purpose,
     duly endorsed or accompanied by a proper instrument of transfer with all
     required certifications completed; and

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

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

     Section 18.  Concerning the Rights Agent.  The Company agrees to pay to the
Rights Agent reasonable compensation for all services rendered by it hereunder
in accordance with a fee schedule to be mutually agreed upon 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
Rights Agreement and the exercise and performance of its duties hereunder.  The
Company also agrees to indemnify the Rights Agent for, and to hold it harmless
against, any loss, liability, or expense, incurred without negligence, bad faith
or willful misconduct on the part of the Rights Agent, for anything done or
omitted by the Rights Agent in connection with the acceptance and administration
of this Rights Agreement, including the costs and expenses of defending against
any claim of liability in the premises. Notwithstanding anything to the contrary
in this Agreement, in no event shall the Rights Agent be liable for special,
indirect or consequential loss or





                                       19
<PAGE>   21
damage of any kind whatsoever, even if the Rights Agent has been advised of the
likelihood of such loss or damage and regardless of the form of action.

     The Rights Agent shall be protected and shall incur no liability for or in
respect of any action taken, suffered or omitted by it in connection with its
administration of this Rights Agreement in reliance upon any Right Certificate
or certificate for the Preferred Shares or the Common Shares or for other
securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, instruction, 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.

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

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

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

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

     20.2  Certificates as to Facts or Matters.  Whenever in the performance of
its duties under this Rights Agreement the Rights Agent shall deem it necessary
or desirable that any fact or matter be proved or established by the Company
prior to taking or suffering any action hereunder, such fact or matter (unless
other evidence in respect thereof be herein specifically prescribed) may be
deemed to be conclusively proved and established by a certificate signed by any
one of the Chairman of the Board of Directors, the Chief Executive Officer, the
President, the Chief Financial Officer, any Vice President, the Treasurer, the
Secretary or any Assistant Treasurer or Assistant Secretary of the Company and
delivered to the Rights Agent; and such





                                       20
<PAGE>   22
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 Rights
Agreement in reliance upon such certificate.

     20.3  Standard of Care.  The Rights Agent shall be liable hereunder only
for its own negligence, bad faith or willful misconduct.

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

     20.5  No Responsibility as to Certain Matters.  The Rights Agent shall not
be under any responsibility in respect of the validity of this Rights Agreement
or the execution and delivery hereof (except the due execution hereof by the
Rights Agent) or in respect of the validity or execution of any Right
Certificate (except its countersignature thereof); nor shall it be responsible
for any breach by the Company of any covenant or condition contained in this
Rights Agreement or in any Right Certificate; nor shall it be responsible for
any change in the exercisability of the Rights (including the Rights becoming
void pursuant to Section 11.1.2) or any adjustment required under the provisions
of Sections 3, 11, 13, 23 or 27 or responsible for the manner, method or amount
of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights
evidenced by Right Certificates after actual notice of any such adjustment); nor
shall it by any act hereunder be deemed to make any representation or warranty
as to the authorization or reservation of any Preferred Shares to be issued
pursuant to this Rights Agreement or any Right Certificate or as to whether any
Preferred Shares will, when so issued, be validly authorized and issued, fully
paid and nonassessable.

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

     20.7  Authorized Company Officers.  The Rights Agent is hereby authorized
and directed to accept instructions with respect to the performance of its
duties hereunder from any one of the Chairman of the Board of Directors, the
Chief Executive Officer, the President, the Chief Financial Officer, any Vice
President, the Treasurer, the Secretary or any Assistant Treasurer or Assistant
Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties under this Rights Agreement, and it
shall not be liable for any action taken or suffered to be taken by it in good
faith in accordance with instructions of any such officer or for any delay in
acting while waiting for these instructions.  Any application by the Rights
Agent for written instructions from the Company may, at the option of the Rights
Agent, set forth in writing any action proposed to be taken or omitted by the
Rights Agent with respect to its duties or obligations under this Rights
Agreement and the date on and/or after which such action shall be taken or
omitted.  The Rights Agent shall not be liable to the Company for any action
taken or omitted in accordance with a proposal included in any such application
on or after the date specified therein (which date shall not be less than three
business days after the date any such officer actually receives such
application, unless any such officer shall have consented in writing to an
earlier date) unless, prior to taking of any such action (or the effective date
in the case of omission), the Rights Agent shall have received written
instructions in response to such application specifying the action to be taken
or omitted.

     20.8  Freedom to Trade in Company Securities.  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 


                                       21

<PAGE>   23
of the Company or become
pecuniarily interested in any transaction in which the Company may be
interested, or contract with or lend money to the Company or otherwise act as
fully and freely as though it were not Rights Agent under this Rights Agreement.
Nothing herein shall preclude the Rights Agent from acting in any other capacity
for the Company or for any other legal entity.

     20.9  Reliance on Attorneys and Agents.  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, omission, default,
neglect or misconduct of any such attorneys or agents or for any loss to the
Company resulting from any such act, omission, default, neglect or misconduct,
PROVIDED that reasonable care was exercised in the selection and continued
employment thereof.

     20.10  Rights Holders List.  At any time and from time to time after the
Distribution Date, upon the request of the Company, the Rights Agent shall
promptly deliver to the Company a list, as of the most recent practicable date
(or as of such earlier date as may be specified by the Company), of the holders
of record of Rights.

     Section 21.  Change of Rights Agent.  The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Rights
Agreement upon thirty (30) days' notice in writing mailed to the Company and to
each transfer agent of the Common Shares and/or Preferred Shares, as applicable,
by registered or certified mail.  The Company shall promptly notify the holders
of the Right Certificates by first-class mail of any such resignation.  The
Company may remove the Rights Agent or any successor Rights Agent upon thirty
(30) days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares
and/or Preferred Shares, as applicable, by registered or certified mail, and to
the holders of the Right Certificates by first- class mail.  If the Rights Agent
shall resign or be removed or shall otherwise become incapable of acting, the
resigning, removed, or incapacitated Rights Agent shall remit to the Company, or
to any successor Rights Agent designated by the Company, all books, records,
funds, certificates or other documents or instruments of any kind then in its
possession which were acquired by such resigning, removed or incapacitated
Rights Agent in connection with its services as Rights Agent hereunder, and
shall thereafter be discharged from all duties and obligations hereunder.
Following notice of such removal, resignation or incapacity, the Company shall
appoint a successor to such Rights Agent.  If the Company shall fail to make
such appointment within a period of thirty (30) days after giving notice of such
removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Company), then the registered holder of any Right Certificate
may apply to any court of competent jurisdiction for the appointment of a new
Rights Agent.  Any successor Rights Agent, whether appointed by the Company or
by such a court, shall be a corporation organized and doing business under the
laws of the United States or of the State of New York (or any other state of the
United States so long as such corporation is authorized to do business as a
banking institution in the State of New York) in good standing, having a
principal office in the State of New York, which is authorized under such laws
to exercise stock transfer or corporate trust powers and is subject to
supervision or examination by Federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $10 million.  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 Shares and/or Preferred Shares, as applicable, and mail a notice
thereof in





                                       22
<PAGE>   24
writing to the registered holders of the Right Certificates.  Failure to give
any notice provided for in this Section 21, however, or any defect therein,
shall not affect the legality or validity of the resignation or removal of the
Rights Agent or the appointment of the successor Rights Agent, as the case may
be.

     Section 22.  Issuance of New Right Certificates. Notwithstanding any of the
provisions of this Rights Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares or
other securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Rights Agreement. In addition, in
connection with the issuance or sale of Common Shares following the Distribution
Date and prior to the redemption, exchange, termination or expiration of the
Rights, the Company (a) shall, with respect to Common Shares so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement, granted or awarded as of the Distribution Date, or upon exercise,
conversion or exchange of securities hereinafter issued by the Company, and (b)
may, in any other case, if deemed necessary or appropriate by the Board of
Directors of the Company, issue Right Certificates representing the appropriate
number of Rights in connection with such issuance or sale; PROVIDED, HOWEVER,
that (i) no such Right 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 Right Certificate would be issued, (ii) no such Right
Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof and (iii) at the
time of a determination by the Board of Directors to cause the Company to issue
a Right Certificate under clause (b) above, there must be Continuing Directors
then in office and any such determination shall require the approval of at least
a majority of such Continuing Directors.

     Section 23.  Redemption.

     23.1  Right to Redeem.  The Board of Directors of the Company may, at its
option, at any time prior to the close of business on the tenth day following
the Shares Acquisition Date, redeem all but not less than all of the then
outstanding Rights at a redemption price of $0.01 per Right, appropriately
adjusted to reflect any stock split, stock dividend, recapitalization or similar
transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "Redemption Price"), PROVIDED, HOWEVER, that if
the Board of Directors of the Company authorizes redemption of the Rights after
the time a Person becomes an Acquiring Person, then there must be Continuing
Directors then in office and such authorization shall require the approval of at
least a majority of such Continuing Directors.  The preceding sentence
notwithstanding, prior to the expiration of the period during which the Rights
may be redeemed as specified therein (or such longer period as the Board of
Directors of the Company may select pursuant to this sentence), the Board of
Directors of the Company may extend, one or more times, the period during which
the Rights may be redeemed beyond the close of business on the tenth day
following the Shares Acquisition Date; PROVIDED, HOWEVER, that there must be
Continuing Directors then in office and any such extension shall require the
approval of at least a majority of such Continuing Directors. Anything contained
in this Rights Agreement to the contrary notwithstanding, the Rights shall not
be exercisable following a transaction or event described in Section 11.1.2
prior to the expiration of the Company's right of redemption hereunder.

     23.2  Redemption Procedures.  Immediately upon the action of the Board of
Directors 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.  Within ten (10) days after
the action of the Board of Directors ordering the redemption of the Rights, the
Company shall give, or cause the Rights Agent to give, notice of such redemption
to the holders of the then outstanding Rights by mailing such notice to all such





                                       23
<PAGE>   25
holders at their last addresses as they appear upon the registry books of the
Rights Agent or, prior to the Distribution Date, on the registry books of the
transfer agent for the Common Shares.  Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice.  Each such notice of redemption will state the method by which the
payment of the Redemption Price will be made.  Neither the Company nor any of
its Affiliates or Associates may redeem, acquire or purchase for value any
Rights at any time in any manner other than that specifically set forth in this
Section 23 or in Section 27, and other than in connection with the purchase,
acquisition or redemption of Common Shares prior to the Distribution Date.

     Section 24.  Notice of Certain Events.  In case the Company shall propose
at any time after the Distribution Date (a) to pay any dividend payable in stock
of any class to the holders of Preferred Shares or to make any other
distribution to the holders of Preferred Shares (other than a regular periodic
cash dividend at a rate not in excess of 125% of the rate of the last regular
periodic cash dividend theretofore paid or, in case regular periodic cash
dividends have not theretofore been paid, at a rate not in excess of 50% of the
average net income per share of the Company for the four quarters ended
immediately prior to the payment of such dividends, or a stock dividend on, or a
subdivision, combination or reclassification of the Common Shares), or (b) to
offer to the holders of Preferred Shares rights or warrants to subscribe for or
to purchase any additional Preferred Shares or shares of stock of any class or
any other securities, rights or options, or (c) to effect any reclassification
of its Preferred Shares (other than a reclassification involving only the
subdivision of outstanding Preferred Shares), or (d) to effect any consolidation
or merger into or with, or to effect any sale or other transfer (or to permit
one or more of its Subsidiaries to effect any sale or other transfer), in one or
more transactions, of 50% or more of the assets or earning power of the Company
and its Subsidiaries (taken as a whole) to, any other Person (other than
pursuant to a merger or other acquisition agreement of the type described in
Section 1.3(ii)(A)(2)), or (e) to effect the liquidation, dissolution or winding
up of the Company, or (f) to declare or pay any dividend on the Common Shares
payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to the Rights Agent and to each holder of a Right Certificate, in
accordance with Section 25, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, distribution of
rights or warrants, or the date on which such reclassification, consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to take place
and the date of participation therein by the holders of the Preferred Shares
and/or Common Shares, if any such date is to be fixed, and such notice shall be
so given in the case of any action covered by clause (a) or (b) above at least
ten (10) days prior to the record date for determining holders of the Preferred
Shares for purposes of such action, and in the case of any such other action, at
least ten (10) days prior to the date of the taking of such proposed action or
the date of participation therein by the holders of the Preferred Shares and/or
Common Shares, whichever shall be the earlier.

     In case any event set forth in Section 11.1.2 of this Rights Agreement
shall occur, then, in any such case, (i) the Company shall as soon as
practicable thereafter give to the Rights Agent and to each holder of a Right
Certificate, in accordance with Section 25, a notice of the occurrence of such
event, which notice shall describe the event and the consequences of the event
to holders of Rights under Section 11.1.2, and (ii) all references in this
Section 24 to Preferred Shares shall be deemed thereafter to refer to Common
Shares and/or, if appropriate, other securities.

     Notwithstanding anything in this Rights Agreement to the contrary, prior to
the Distribution Date a filing by the Company with the Securities and Exchange
Commission shall constitute sufficient notice to the holders of securities of
the Company, including the Rights, for purposes of this Rights Agreement and no
other notice need be given.

the Company or the Rights Agent to the holder of any Right Certificate (or,
prior to the Distribution Date, to the holder of any certificate representing
Common Shares) 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

     Section 26.  Supplements and Amendments.  Prior to the Distribution Date
and subject to the last sentence of this Section 26, the Company and the Rights
Agent may, if the Company so directs, supplement or amend any provision of this
Rights Agreement without the approval of any holders of certificates
representing Common Shares.  From and after the Distribution Date and subject to
the last sentence of this Section 26, the Company and the Rights Agent may from
time to time supplement or amend this Rights Agreement without the approval of
any holders of Right Certificates (i) to cure any ambiguity or to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, (ii) to shorten or lengthen any time period
hereunder (which shortening or lengthening, after the time a Person becomes an
Acquiring Person, shall be effective only if there are Continuing Directors and
shall require the approval of at least a majority of such Continuing Directors)
or (iii) so long as the interests of the holders of the Right Certificates
(other than an Acquiring Person or an Affiliate or Associate of an Acquiring
Person) are not adversely affected thereby, to make any other changes or
provisions in regard to matters or questions arising hereunder which the Company
and the Rights Agent may deem necessary or desirable, including but not limited
to extending the Final Expiration Date; PROVIDED, HOWEVER, that the right of the
Board of Directors to extend the Distribution Date or Redemption Date shall not
require any amendment or supplement hereunder.  Upon the delivery of a
certificate from an appropriate officer of the Company which states that the
proposed supplement or amendment is in compliance with the terms of this Section
26, the Rights Agent shall execute such supplement or amendment.  Prior to the
Distribution Date, the interests of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Shares.  Without limiting
the foregoing, at any time prior to such time as any Person becomes an Acquiring
Person, the Company and the Rights Agent may amend this Agreement to lower the
thresholds set forth in Sections 1.1 and 3.1 to not less than the greater of (i)
any percentage greater than the largest percentage of the outstanding Common
Shares then known by the Company to be beneficially owned by any Person (other
than the





                                       25
<PAGE>   27
Company, any Subsidiary of the Company, any employee benefit plan of the
Company or any Subsidiary of the Company, or any entity holding Common Shares
for or pursuant to the terms of any such plan) and (ii) 10%.

     Section 27.  Exchange.

     27.1  Exchange of Common Shares for Rights.  The Board of Directors of the
Company may, at its option, at any time after the occurrence of a Trigger Event,
exchange Common Shares for all or part of the then outstanding and exercisable
Rights (which shall not include Rights that have become void pursuant to the
provisions of Section 11.1.2) by exchanging that number of Common Shares having
an aggregate value equal to the Spread (with such value being based on the
current per share market price (as determined pursuant to Section 11.4) on the
date of the occurrence of a Trigger Event) per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such amount per Right being hereinafter referred to as the
"Exchange Consideration"). Notwithstanding the foregoing, (i) the Board of
Directors shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Shares then outstanding and (ii) the Board shall not be
empowered to effect an exchange for more than that number of Rights for which
there are sufficient Common Shares authorized but unissued, or held by the
Company as treasury shares, to permit the exchange for Rights.

     27.2  Exchange Procedures.  Immediately upon the action of the Board of
Directors of the Company ordering the exchange for any Rights pursuant to
Section 27.1 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange
Consideration.  The Company shall promptly give public notice of any such
exchange; PROVIDED, HOWEVER, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange.  The Company promptly
shall mail a notice of any such exchange to all of the holders of such Rights at
their last addresses as they appear upon the registry books of the Rights Agent.
Any notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice.  Each such notice of exchange
will state the method by which the exchange of the Common Shares for Rights will
be effected and, in the event of any partial exchange, the number of Rights
which will be exchanged.  Any partial exchange shall be effected pro rata based
on the number of Rights (other than the Rights which have become void pursuant
to the provisions of Section 11.1.2) held by each holder of Rights.

     27.3  No Fractional Shares Upon Exchange.  The Company shall not be
required to issue fractions of Common Shares or to distribute certificates which
evidence fractional Common Shares.  In lieu of such fractional Common Shares,
the Company shall pay to the registered holders of the Right Certificates, with
regard to which such fractional Common Shares would otherwise be issuable, in an
amount in cash equal to the same fraction of the current market value of a whole
Common Share.  For the purposes of this Section 27.3, the current market value
of a whole Common Share shall be the current per share market price (as
determined pursuant to Section 11.4) for the Trading Day immediately prior to
the date of exchange pursuant to this Section 27.

     Section 28.  Successors.  All the covenants and provisions of this Rights
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.  Benefits of this Rights Agreement.  Nothing in this Rights
Agreement shall be construed to give to any Person or corporation other than the
Company, the Rights Agent and the registered holders of the Right Certificates
(and, prior to the Distribution Date, the Common Shares) any legal or equitable
right, remedy or claim under this Rights Agreement; but this Rights Agreement
shall be for the sole and exclusive benefit of the Company, the Rights Agent and
the registered holders of the Right Certificates (and, prior to the Distribution
Date, the Common Shares).

     Section 30.  Severability.  If any term, provision, covenant or restriction
of this Rights 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 Rights Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

     Section 31.  Governing Law.  This Rights Agreement and each Right
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 to
be made and performed entirely within such State.

     Section 32.  Counterparts.  This Rights 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 33.  Descriptive Heading.  Descriptive headings of the several
Sections of this Rights Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

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

                         _____________________________


         Tegal Corporation, a corporation organized and existing under the
General Corporation Law of the State of Delaware (hereinafter called the
"Corporation"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law at a meeting duly called and held on June 11, 1996.

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

         Series A Junior Participating Preferred Stock:

         Section 1.  Designation and Amount.  The shares of such series shall
be designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 350,000.  Such number of shares may be increased or decreased by
resolution of the Board of Directors; PROVIDED, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

         Section 2.  Dividends and Distributions.

                 (A) Subject to the rights of the holders of any shares of any
         series of Preferred Stock (or any similar stock) ranking prior and
         superior to the Series A Preferred Stock with respect to dividends,
         the holders of shares of Series A Preferred Stock, in preference to
         the holders of Common Stock, par





                                      A-1
<PAGE>   31
         value $.01 per share (the "Common Stock"), of the Corporation, and of
         any other junior stock, shall be entitled to receive, when, as and if
         declared by the Board of Directors out of funds legally available for
         the purpose, quarterly dividends payable in cash on the first day of
         March, June, September and December in each year (each such date being
         referred to herein as a "Quarterly Dividend Payment Date"), commencing
         on the first Quarterly Dividend Payment Date after the first issuance
         of a share or fraction of a share of Series A Preferred Stock, in an
         amount per share (rounded to the nearest cent) equal to the greater of
         (a) $1.00 or (b) subject to the provision for adjustment hereinafter
         set forth, 100 times the aggregate per share amount of all cash
         dividends, and 100 times the aggregate per share amount (payable in
         kind) of all non-cash dividends or other distributions, other than a
         dividend payable in shares of Common Stock or a subdivision of the
         outstanding shares of Common Stock (by reclassification or otherwise),
         declared on the Common Stock since the immediately preceding Quarterly
         Dividend Payment Date or, with respect to the first Quarterly Dividend
         Payment Date, since the first issuance of any share or fraction of a
         share of Series A Preferred Stock. In the event the Corporation shall
         at any time declare or pay any dividend on the Common Stock payable in
         shares of Common Stock, or effect a subdivision, combination or
         consolidation of the outstanding shares of Common Stock (by
         reclassification or otherwise than by payment of a dividend in shares
         of Common Stock) into a greater or lesser number of shares of Common
         Stock, then in each such case the amount to which holders of shares of
         Series A Preferred Stock were entitled immediately prior to such event
         under clause (b) of the preceding sentence shall be adjusted by
         multiplying such amount by a fraction, the numerator of which is the
         number of shares of Common Stock outstanding immediately after such
         event and the denominator of which is the number of shares of Common
         Stock that were outstanding immediately prior to such event.

                 (B)  The Corporation shall declare a dividend or distribution
         on the Series A Preferred Stock as provided in paragraph (A) of this
         Section 2 immediately after it declares a dividend or distribution on
         the Common Stock (other than a dividend payable in shares of Common
         Stock); provided that, in the event no dividend or distribution shall
         have been declared on the Common Stock during the period between any
         Quarterly Dividend Payment Date and the next subsequent Quarterly
         Dividend Payment Date, a dividend of $1.00 per share on the Series A
         Preferred Stock shall nevertheless be payable on such subsequent
         Quarterly Dividend Payment Date.

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





                                      A-2
<PAGE>   32
         Section 3.  Voting Rights.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

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

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

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

         Section 4. Certain Restrictions.

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

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

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

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





                                      A-3
<PAGE>   33
                         (iv)  redeem or purchase or otherwise acquire for
                 consideration any shares of Series A Preferred Stock, or any
                 shares of stock ranking on a parity with the Series A Preferred
                 Stock, except in accordance with a purchase offer made in
                 writing or by publication (as determined by the Board of
                 Directors) to all holders of such shares upon such terms as the
                 Board of Directors, after consideration of the respective
                 annual dividend rates and other relative rights and preferences
                 of the respective series and classes, shall determine in good
                 faith will result in fair and equitable treatment among the
                 respective series or classes.

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

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

         Section 6.  Liquidation, Dissolution or Winding Up.  Upon any
liquidation, dissolution or winding up of the Corporation, no distribution
shall be made (1) to the holders of shares of stock ranking junior (either as
to dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not
declared, to the date of such payment, provided that the holders of shares of
Series A Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
100 times the aggregate amount to be distributed per share to holders of shares
of Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with
the Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up.  In the event the Corporation shall at any time
declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision, combination or consolidation of the outstanding
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in shares of Common Stock) into a greater or lesser number of shares
of Common Stock, then in each such case the aggregate amount to which holders
of shares of Series A Preferred Stock were entitled immediately prior to such
event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that are
outstanding immediately prior to such event.

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

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

         Section 9.  Rank.  The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets, junior to
all series of any other class of the Corporation's Preferred Stock, except to
the extent that any such other series specifically provides that it shall rank
on a parity with or junior to the Series A Preferred Stock.

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

                 This Right Certificate is subject to all of the terms,
provisions and conditions of the Rights Agreement, which terms, provisions and
conditions are hereby incorporated herein by reference and made a part
hereof and to which Rights Agreement reference is hereby made for a full
description of the rights, limitations of rights, obligations, duties and
immunities hereunder of the Rights Agent, the Company and the holders of the

principal offices of the Company and the Rights Agent.

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

                 Subject to the provisions of the Rights Agreement, the Board

the Rights evidenced by this Certificate, in whole or in part, after the
occurrence of a Trigger Event.  The period during which redemption of the
Rights is permitted may be extended by the Board of Directors of the Company,

Continuing Directors.  Under certain circumstances set forth in the Rights
Agreement, the decision to redeem shall require the concurrence of a majority
of the Continuing Directors.

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

entitled to vote or receive dividends or be deemed for any purpose the holder
of the Preferred Shares or of any other securities of the Company which may at
any time be issuable on the exercise hereof, nor shall anything contained in
the Rights Agreement or herein be construed to confer upon the holder hereof,
as such, any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action, or
to receive notice of meetings or other actions affecting stockholders (except
as provided in the Rights Agreement), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this Right
Certificate shall have been exercised as provided in the Rights Agreement.

                 If any term, provision, covenant or restriction of the Rights
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 the Rights Agreement shall remain in full force
and effect and shall in no way be affected, impaired or invalidated.

                 This Right Certificate shall not be valid or binding for any

         As described in the Rights Agreement, Rights which are held by
       or have been held by Acquiring Persons or Associates or Affiliates
    thereof (as defined in the Rights Agreement) shall become null and void.

                         SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

            On June 11, 1996 the Board of Directors of Tegal Corporation (the
"Company") declared a dividend of one Right for each share of common stock,
$.01 par value (the "Common Shares"), of the Company outstanding at the close
of business on July 1, 1996 (the "Record Date").  As long as the Rights are
attached to the Common Shares, the Company will issue one Right (subject to
adjustment) with each new Common Share so that all such shares will have
attached Rights.  When exercisable, each Right will entitle the registered
holder to purchase from the Company one one-hundredth of a share of Series A
Junior Participating Preferred Stock (the "Preferred Shares") at a price of
$45.00 per one one- hundredth of a Preferred Share, subject to adjustment (the
"Purchase Price").  The description and terms of the Rights are set forth in a
Rights Agreement, dated as of June 11, 1996, as the same may be amended from
time to time (the "Rights Agreement"), between the Company and CHASEMELLON
SHAREHOLDER SERVICES, L.L.C., as Rights Agent (the "Rights Agent").

            Until the earlier to occur of (i) ten (10) days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 15% or more of the Common Shares or (ii) ten (10) days following
the commencement or announcement of an intention to make a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the Common Shares (the earlier
of (i) and (ii) being called the "Distribution Date," whether or not either
such date occurs prior to the Record Date), the Rights will be evidenced, with
respect to any of the Common Share certificates outstanding as of the Record
Date, by such Common Share certificate together with a copy of this Summary of
Rights.

            The Rights Agreement provides that the Board of Directors, with the
concurrence of a majority of the Continuing Directors (as defined below), may
postpone the Distribution Date and that, until the Distribution Date, the
Rights will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the close of business on the Record Date
upon transfer or new issuance of the Common Shares will contain a notation
incorporating the Rights Agreement by reference.  Until the Distribution Date
(or earlier redemption, exchange, termination or expiration of the Rights), the
surrender for transfer of any certificates for Common Shares, with or without a
copy of this Summary of Rights, will also constitute the transfer of the Rights
associated with the Common Shares represented by such certificate.  As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right Certificates") will be mailed to holders of record of the
Common Shares as of the close of business on the Distribution Date and such
separate Right Certificates alone will evidence the Rights.

            The Rights are not exercisable until the Distribution Date.  The
Rights will expire on June 11, 2006, subject to the Company's right to extend
such date (the "Final Expiration Date"), unless earlier redeemed or exchanged
by the Company or terminated.

            Each Preferred Share purchasable upon exercise of the Rights will
be entitled to a minimum preferential quarterly dividend payment of $1.00 per
share but will be entitled to an aggregate dividend of 100 times the dividend,
if any, declared per Common Share.  In the event of liquidation, the holders of 
the





                                      C-1
<PAGE>   44
Preferred Shares will be entitled to a minimum preferential liquidation
payment of $100 per share but will be entitled to an aggregate payment of 100
times the payment made per Common Share.  Each Preferred Share will have 100
votes and will vote together with the Common Shares.  Finally, in the event of
any merger, consolidation or other transaction in which Common Shares are
exchanged, each Preferred Share will be entitled to receive 100 times the
amount received per Common Share.  These rights are protected by customary
antidilution provisions.  Because of the nature of the Preferred Share's
dividend, liquidation and voting rights, the value of one one-hundredth of a
Preferred Share purchasable upon exercise of each Right should approximate the
value of one Common Share.

            The Purchase Price payable, and the number of Preferred Shares or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain
rights or warrants to subscribe for or purchase Preferred Shares or convertible
securities at less than the current market price of the Preferred Shares or
(iii) upon the distribution to holders of the Preferred Shares of evidences of
indebtedness, cash, securities or assets (excluding regular periodic cash
dividends at a rate not in excess of 125% of the rate of the last regular
periodic cash dividend theretofore paid or, in case regular periodic cash
dividends have not theretofore been paid, at a rate not in excess of 50% of the
average net income per share of the Company for the four quarters ended
immediately prior to the payment of such dividend, or dividends payable in
Preferred Shares (which dividends will be subject to the adjustment described
in clause (i) above)) or of subscription rights or warrants (other than those
referred to above).

            In the event that a Person becomes an Acquiring Person (except
pursuant to certain cash offers for all outstanding Common Shares approved by
the Board) or if the Company were the surviving corporation in a merger with an
Acquiring Person or any affiliate or associate of an Acquiring Person and the
Common Shares were not changed or exchanged, each holder of a Right, other than
Rights that are or were acquired or beneficially owned by the 15% stockholder
(which Rights will thereafter be void), will thereafter have the right to
receive upon exercise that number of Common Shares having a market value of two
times the then current Purchase Price of the Right.  With certain exceptions,
in the event that the Company were acquired in a merger or other business
combination transaction or more than 50% of its assets or earning power were
sold, proper provision shall be made so that each holder of a Right shall
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction would have a market
value of two times the then current Purchase Price of the Right.

            At any time after a Person becomes an Acquiring Person and prior to
the acquisition by such Acquiring Person of 50% or more of the outstanding
Common Shares, the Board of Directors may cause the Company to acquire the
Rights (other than Rights owned by an Acquiring Person which have become void),
in whole or in part, in exchange for that number of Common Shares having an
aggregate value equal to the Spread (the excess of the value of the Common
Shares issuable upon exercise of a Right after a Person becomes an Acquiring
Person over the Purchase Price) per Right (subject to adjustment).

            No adjustment in the Purchase Price will be required until
cumulative adjustments require an adjustment of at least 1% in such Purchase
Price. No fractional shares will be issued and in lieu thereof, a payment in
cash will be made based on the market price of the Preferred Shares on the last
trading date prior to the date of exercise.

            The Rights may be redeemed in whole, but not in part, at a price of
$0.01 per Right (the "Redemption Price") by the Board of Directors at any time
prior to the close of business on the tenth day following the first date of
public announcement that a Person has become an Acquiring Person.  The Board





                                      C-2
<PAGE>   45
of Directors, with the concurrence of a majority of the Continuing Directors
(as defined below), may extend the period during which the Rights are
redeemable beyond the ten (10) days following the public announcement that a
Person has become an Acquiring Person.  Under certain circumstances set forth
in the Rights Agreement, the decision to redeem shall require the concurrence
of a majority of the Continuing Directors.  Immediately upon the action of the
Board of Directors of the Company electing to redeem the Rights, the Company
shall make an announcement thereof, and upon such election, the right to
exercise the Rights will terminate and the only right of the holders of Rights
will be to receive the Redemption Price.

            The term "Continuing Directors" means any member of the Board of
Directors of the Company who was a member of the Board prior to the time that
any Person becomes an Acquiring Person, and any person who is subsequently

FOR IMMEDIATE RELEASE

                TEGAL CORPORATION DECLARES DIVIDEND DISTRIBUTION
                       OF PREFERRED SHARE PURCHASE RIGHTS


PETALUMA, Calif., June 11, 1996 -- The Board of Directors of Tegal Corporation
(Nasdaq: TGAL) today declared a dividend distribution of one Preferred Share
Purchase Right on each outstanding share of Tegal Corporation common stock.
Each Right will entitle stockholders to buy one one-hundredth of a share of a
newly created Series A Junior Participating Preferred Stock of the Company at
an exercise price of $45.00. The Rights will be exercisable if a person or
group acquires 15 percent or more of the Company's common stock or announce a
tender offer for 15 percent or more of the common stock; provided, however,
that if any person or group owns 15 percent or more of the Company's common
stock as of June 11, 1996, then the Rights would become exercisable with
respect to such person or group only after such person or group acquires
beneficial ownership of any additional shares of the Company's common stock.
Tegal Corporation Board will be entitled to redeem the Rights at 0.01 cent per
Right at any time before the tenth day after the person has acquired 15 percent
or more of the outstanding common stock.

The Rights are not being distributed in response to any specific effort to
acquire control of the Company. The Rights are designed to assure all Tegal
Corporation stockholders receive fair and equal treatments in the event of any
proposed takeover of the Company and to guard against partial tender offers,
open market accumulations and other abusive tactics to gain control of Tegal
Corporation without paying all stockholders a control premium.

If a person acquires 15 percent or more of the outstanding common stock of
Tegal Corporation, each Right will entitle its holder to purchase, at the
Right's then-current exercise price, a number of common shares of Tegal
Corporation having a market value at that time of twice the Right's exercise
price. Rights held by the 15 percent holder will become void and will not be
exercisable to purchase shares at the bargain purchase price. If Tegal
Corporation is acquired in a merger or

other business combination transaction which has not been approved by the Board
of Directors, each Right will entitle its holder to purchase, at the Right's
then-current exercise price, a number of the acquiring company's common shares
having a market value at that time of twice the Right's exercise price.

"The Rights are intended to enable all Tegal Corporation stockholders to
realize the long-term value of their investment in the Company. They do not
prevent a takeover, but should encourage anyone seeking to acquire the Company
to negotiate with the Board of Directors prior to attempting a takeover," said
Robert V. Hery, Chief Executive Officer of Tegal Corporation.

The dividend distribution will be payable to stockholders of record on July 1,
1996. The Rights will expire in ten years. The Rights distribution is not 
taxable to stockholders.

Tegal Corporation, headquartered in Petaluma, California is a leading designer
and manufacturer of plasma etch systems used in the fabrication of integrated
circuits (ICs). Etching is a key process and must be performed multiple times
in regions of the world in which ICs are manufactured.
