                      AMENDED AND RESTATED RIGHTS AGREEMENT
                      -------------------------------------


          THIS AMENDED AND RESTATED RIGHTS AGREEMENT is dated as of February 13,
1996 and amends and restates in its entirety that certain Rights Agreement dated
as of August 31, 1989 between Vivra Incorporated, a Delaware corporation (the
"Company"), and The First National Bank of Boston (the "Rights Agent").

          The Board of Directors of the Company authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding on August 31, 1989 (the
"Record Date"), each Right representing the right to purchase one one-hundredth
of a Preferred Share (as hereinafter defined), and further authorized and
directed the issuance of one Right with respect to (i) each Common Share of the
Company that shall become outstanding between the Record Date and the earliest
of the Distribution Date, the Redemption Date and the Final Expiration Date and
(ii) at the sole discretion of the Board of Directors each Common Share of the
Company that shall be issued by the Company outstanding following the
Distribution Date and before the earlier of the Redemption Date and the Final
Expiration Date and as to which the Board of Directors specifically determines
to issue a Right therewith.

          The Board of Directors subsequently authorized the amendment and
restatement of this Agreement, to provide, among other things, that all
provisions of this Agreement relating to adjustment to the Rights and the
Purchase Price shall apply as if the Rights were declared as of February 13,
1996, and no adjustments which would otherwise be required to be made pursuant
to Section 11 of this Agreement shall be made with respect to the period between
August 31, 1989 and February 13, 1996, all such adjustments having been taken
into account herein.

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

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

          "Acquiring Person" shall mean any Person who or which, together with
all Affiliates and Associates of such Person, shall be the Beneficial Owner of
15% or more of the Common Shares of the Company then outstanding, but shall not
include the Company, any Subsidiary of the Company, any employee benefit plan of
the Company or any Subsidiary of the Company, or any entity holding Common
Shares for or pursuant to the terms of any such plan.  Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of

                                       -1-

<PAGE>

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 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."  In addition, the term
"Acquiring Person" shall not include any Grandfathered Person.

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

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

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

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

                                       -2-

<PAGE>

     Exchange Act (or any comparable or successor report); or

          (iii)  which are beneficially owned, directly or indirectly, by any
     other Person 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) for the
     purpose of acquiring, holding, voting (except to the extent contemplated by
     the proviso to paragraph(ii)(B) above) or disposing of any securities of
     the Company.

          Notwithstanding anything in this definition of beneficial ownership to
the contrary, any securities which are not outstanding but which are subject to
options, warrants, rights or conversion privileges shall be deemed to be
outstanding for the purpose of computing the percentage of outstanding
securities of the class owned by the person holding such options, warrants,
rights or conversion privileges but shall not be deemed to be outstanding for
the purpose of computing the percentage of the class owned by any other person
or for calculating the total number of outstanding shares of the Company.

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

          "Close of business" on any given date shall mean 5:00 P.M., San
Francisco, California time, on such date; provided, however, that if such date
                                          --------  -------
is not a Business Day it shall mean 5:00 P.M., San Francisco, California time,
on the next succeeding Business Day.

          "Common Shares" when used with reference to the Company shall mean the
shares of common stock, par value $.01 per share, of the Company.  "Common
Shares" when used with reference to any Person other than the Company shall mean
the capital stock (or equity interest) with the greatest voting power of such
other Person or, if such other Person is a Subsidiary of another Person, the
Person or Persons which ultimately control such first-mentioned Person.

          "Distribution Date" shall have the meaning set forth in Section 3
hereof.

          "Final Expiration Date" shall have the meaning set forth in Section 7
hereof.

                                       -3-

<PAGE>

          "Grandfathered Person" shall mean any Person who, or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
on February 13, 1996 of at least 15% but no more than 20% of the Common Shares
of the Company outstanding as of February 13, 1996; provided, however, that such
Person shall not be deemed a Grandfathered Person if such Person together with
the Affiliates and Associates of such Person acquires after February 13, 1996
additional Common Shares of the Company and after such acquisition such Person,
together with all Affiliates and Associates of such Person, is the Beneficial
Owner of 15% or more of the Common Shares of the Company outstanding at the time
of such acquisition.

          "Person" shall mean any individual, firm, partnership, group,
corporation or other entity, and shall include any successor (by merger or
otherwise) of such entity.

          "Preferred Shares" shall mean shares of Series A Junior Participating
Preferred Stock, par value $.01 per share, of the Company having the rights and
preferences set forth in the Form of Certificate of Designation attached to this
Agreement as Exhibit A.

hereof.

          "Subsidiary" of any Person shall mean any corporation or other entity

(ii) any other shares of capital stock of the Company entitled to vote generally
in the election of directors or entitled to vote together with the Common Shares
in respect of any merger, consolidation, sale of all or substantially all of the
Company's assets, liquidation, dissolution or winding up.  Whenever any
provision of this Agreement requires a determination of whether a number of
shares of Voting Stock comprising a specified percentage of such Voting Stock
has been voted, tendered, acquired, sold or otherwise disposed of, or a
determination of whether a Person has offered or proposed to acquire a number of
shares of Voting Stock comprising such specified percentage, the number of
shares of Voting Stock comprising such specified percentage of Voting Stock
shall in every such case be deemed to be the number of shares of Voting Stock
comprising the specified percentage of the Company's entire voting power

                                       -4-

then entitled to vote generally in the election of directors or then entitled to
vote together with the Common Shares in respect of any merger, consolidation,

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

          Section 3.  Issue of Right Certificates.
                      ---------------------------

          (a)  Until the earlier of (i) the tenth day after the Shares
Acquisition Date or (ii) the tenth Business Day (or such later date as may be
determined by action of the Board of Directors prior to such time as any Person
becomes an Acquiring Person) after the date of the commencement by any Person
(other than the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or of any Subsidiary of the Company or any entity holding
Common Shares for or pursuant to the terms of any such plan) of, or of the first
public announcement of the intention 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 Common Shares for or pursuant to
the terms of 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
(including any such date which is after the date of this Agreement and prior to
the issuance of the Rights; the earlier of such dates being herein referred to
as the "Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of Section 3(b) hereof) by the certificates for Common Shares
registered in the names of the holders thereof (which certificates shall also be
deemed to be Right Certificates) and not by separate Right Certificates, and (y)
the right to receive Right Certificates will be transferable only in connection
with the transfer of Common Shares.  As soon as practicable after the
Distribution Date, the Company will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid mail, to each
record holder of Common Shares as of the close of business on the Distribution
Date, at the address of such holder shown on the records of the Company, a Right
Certificate, in substantially the form of Exhibit B hereto (a "Right
Certificate"),

                                       -5-

<PAGE>

evidencing one Right for each Common Share so held.  In addition, at any time
following the Distribution Date but before the earlier of the Redemption Date or
the Final Expiration Date, if the Company shall issue Common Shares and in
connection with such issuance the Board of Directors shall, in its sole
discretion, elect to issue Rights with such Common Shares, the Company will
prepare and execute, the Rights Agent will countersign, and the Company will
deliver at the time of such issuance or will thereafter send or cause to be sent
(and the Rights Agent will, if requested, send) by first-class insured, postage
prepaid, mail, to each record holder of such Common Shares so issued, at the
address of such holder shown on the records of the Company, a Right Certificate
evidencing one right for each Common Share so received (subject to adjustment as
provided herein).  As of the Distribution Date, the Rights will be evidenced
solely by such Right Certificates.

          (b)  Until the Distribution Date (or the earlier of the Redemption
Date or the Final Expiration Date), the surrender for transfer of any
certificate for Common Shares outstanding on the Record Date, with or without a
copy of the Summary of Rights attached thereto, shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby.

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

          This certificate also evidences and entitles the holder hereof to
          certain rights as set forth in a Rights Agreement between Vivra
          Incorporated and The First National Bank of Boston, and dated as of
          August 31, 1989 (as amended and restated, 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 Vivra
          Incorporated.  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.  Vivra Incorporated
          will mail to the holder of this certificate a copy of the Rights
          Agreement without charge after receipt of a written request therefor.
          As described in the Rights Agreement, Rights issued to any Person who
          becomes an Acquiring Person (as defined in the Rights Agreement) shall
          become null and void.

                                       -6-

<PAGE>

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares 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 and of assignment to be
printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Rights may from time to time be listed, or to conform to
usage.  Subject to the provisions of Section 22 hereof, the Right Certificates
shall entitle the holders thereof to purchase such number of one one-hundredths
of a Preferred Share as shall be set forth therein at the price per one
one-hundredth of a Preferred Share set forth therein (the "Purchase Price"), but
the number of such one one-hundredths of a Preferred Share and the Purchase
Price shall be subject to adjustment as provided herein.

          Section 5.  Countersignature and Registration. The Right Certificates
                      ---------------------------------
shall be executed on behalf of the Company by its Chairman of the Board, its
Chief Executive Officer, its President, any of its Vice Presidents, or its
Treasurer, either manually or by facsimile signature, shall have affixed thereto
the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature.  The Right Certificates shall be manually countersigned by
the Rights Agent and shall not be valid for any purpose unless countersigned.
In case any officer of the Company who shall have signed any of the Right
Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the 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

                                       -7-

<PAGE>

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, books for registration and transfer of the
Right Certificates issued hereunder.  Such books shall show the names and
addresses of the respective holders of the Right Certificates, the number of
Rights evidenced on its face by each of the Right Certificates and the date of
each of the Right Certificates.

          Section 6.  Transfer, Split Up, Combination and Exchange of Right
                      -----------------------------------------------------
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.  Subject
- ---------------------------------------------------------------------
to the provisions of Section 14 hereof, at any time after the close of business
on the Distribution Date, and at or prior to the close of business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates,
entitling the registered holder to purchase a like number of one one-hundredths
of a Preferred Share as the Right Certificate or Right Certificates surrendered
then entitled such holder to purchase.  Any registered holder desiring to
transfer, split up, combine or exchange any Right Certificate or Right
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent.  Thereupon the Rights Agent shall countersign and deliver to the
person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested.  The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

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

                                       -8-

<PAGE>

delivery to the registered holder in lieu of the Right Certificate so lost,
stolen, destroyed or mutilated.

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

          (a)  The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein) in whole or in
part at any time after the Distribution Date upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the principal office of the Rights Agent,
together with payment of the Purchase Price for each one one-hundredth of a
Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the close of business on August 31, 1999 (the "Final Expiration
Date"), (ii) the time at which the Rights are redeemed as provided in Section 23
hereof (the "Redemption Date"), or (iii) the time at which such Rights are
exchanged as provided in Section 24 hereof.

          (b)  The Purchase Price for each one one-hundredth of a Preferred
Share pursuant to the exercise of a Right shall be $100.00, shall be subject to
adjustment from time to time on or after February 13, 1996 as provided in
Sections 11 and 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

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

                                       -9-



<PAGE>

holder and (iv) when appropriate, after receipt, deliver such cash to or upon
the order of the registered holder of such Right Certificate.

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

          Section 8.  Cancellation and Destruction of Right Certificates.  All
                      --------------------------------------------------
Right Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this 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.  Availability of Preferred Shares.  The Company covenants
                      --------------------------------
and agrees that it will take all such action as may be necessary to ensure that
all Preferred Shares delivered upon exercise of Rights shall, at the time of
delivery of the certificates for such Preferred Shares (subject to payment of
the Purchase Price), be duly and validly authorized and issued and fully paid
and nonassessable shares.

          The Company further covenants and agrees that it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares upon the exercise of Rights.  The Company shall not,
however, be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right Certificates to a person other than, or the
issuance or delivery of certificates or depositary receipts for the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depositary receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such

                                      -10-

<PAGE>

tax being payable by the holder of such Right Certificate at the time of
surrender) or until it has been established to the Company's reasonable
satisfaction that no such tax is due.

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

          Section 11.  Adjustment of Purchase Price, Number of Shares or Number
                       --------------------------------------------------------
of Rights.  The Purchase Price, the number of Preferred Shares covered by each
- ---------
Right and the number of Rights outstanding are subject to adjustment from time
to time on or after February 13, 1996 as provided in this Section 11.

          (a)  (i) In the event the Company shall at any time on or after
     February 13, 1996 (A) declare a dividend on the Preferred Shares payable in
     Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C)
     combine the outstanding Preferred Shares into a smaller number of Preferred
     Shares or (D) issue any shares of its capital stock in a reclassification
     of the Preferred Shares (including any such reclassification in connection
     with a consolidation or merger in which the Company is the continuing or
     surviving corporation), except as otherwise provided in this Section 11(a),
     the Purchase Price in effect at the time of the record date for such
     dividend or as 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

                                      -11-

<PAGE>

     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; provided, however,
                                                             --------  -------
     that in no event shall the consideration to be paid upon the exercise of
     one Right be less than the aggregate par value of the shares of capital
     stock of the Company issuable upon exercise of one Right.

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

          From and after the occurrence of such event, any Rights that are or
     were acquired or beneficially owned by any Acquiring Person (or any
     Associate or Affiliate of such Acquiring Person) shall be void and any
     holder of such Rights shall thereafter have no right to exercise such
     Rights under any provision of this Agreement.  No Right Certificate shall
     be issued pursuant to Section 3 that represents Rights beneficially owned
     by an Acquiring Person or any Associate or Affiliate thereof whose Rights
     would be void pursuant to the preceding sentence; no Right Certificate
     shall be issued at any time upon the transfer of any Rights to an Acquiring
     Person whose Rights would be void pursuant to the preceding sentence or any
     Associate or Affiliate thereof or to any nominee of such Acquiring Person,
     Associate or Affiliate; and any Right Certificate delivered to the Rights
     Agent for transfer to an Acquiring Person

                                      -12-

<PAGE>

     whose Rights would be void pursuant to the preceding sentence shall be
     cancelled.


          (iii)  In the event that there shall not be sufficient treasury shares
     or authorized but unissued Common Shares to permit the exercise in full of
     the Rights in accordance with the foregoing subparagraph (ii) and the
     Rights become so exercisable, notwithstanding any other provision of this
     Agreement, to the extent necessary and permitted by applicable law and any
     agreements in effect on the date hereof to which the Company is a party,
     each Right shall thereafter represent the right to receive, upon exercise
     thereof at the then current Purchase Price in accordance with the terms of
     this Agreement, a number of shares, or units of shares, of (x) Common
     Shares and (y) preferred stock (or other equity securities) of the Company,
     including, but not limited to, Preferred Shares, equal in the aggregate to
     the number of Adjustment Shares where the Board of Directors of the Company
     shall have deemed such shares or units, other than the Common Shares, to
     have at least the same economic value and voting rights as the Common
     Shares (a "common stock equivalent") (one-hundredth of a share of Preferred
     Stock shall be deemed to be a common stock equivalent); provided, however,
     if there are unavailable a sufficient number of (or fractions of) Common
     Shares and/or common stock equivalents, then the Company shall take all
     such action as may be necessary to authorize additional Common Shares or
     common stock equivalents for issuance upon exercise of the Rights,
     including the calling of a meeting of stockholders; and provided, further,
     that the Company shall issue no common stock equivalent upon exercise of
     the Rights until the Company has first issued all authorized and unreserved
     Common Shares; and provided, further, that if the Company is unable to
     cause sufficient Common Shares and/or common stock equivalents to be
     available for issuance upon exercise in full of the Rights, then each Right
     shall thereafter represent the right to receive the Adjusted Number of
     Common Shares upon exercise at the Adjusted Purchase Price (as such terms
     are hereinafter defined).  As used herein, the term Adjusted Number of
     Common Shares shall be equal to that number of (or fractions of) Common
     Shares (and/or shares or units of common stock equivalents) equal to the
     product of (x) the number of Adjustment Shares and (y) a fraction, the
     numerator of which is the number of Common Shares (and/or shares or units
     of common stock equivalents) available for issuance upon exercise of the
     Rights and the denominator of

                                      -13-

<PAGE>

     which is the aggregate number of Adjustment Shares otherwise issuable upon
     exercise in full of all Rights (assuming there were sufficient Common
     Shares available) (such fraction being referred to as the "Proration
     Factor").  The Adjusted Purchase Price shall mean the product of the
     Purchase Price and the Proration Factor.  The Board of Directors may, but
     shall not be required to, establish procedures to allocate the right to
     receive Common Shares and common stock equivalents upon exercise of the
     Rights among holders of Rights.

          (b)  In case the Company shall fix a record date for the issuance of
     rights, options or warrants to all holders of Preferred Shares entitling
     them (for a period expiring within 45 calendar days after such record date)
     to subscribe for or purchase Preferred Shares (or shares having the same
     rights, privileges and preferences as the Preferred Shares ("equivalent
     preferred shares")) or securities convertible into Preferred Shares or
     equivalent preferred shares at a price per Preferred Share or equivalent
     preferred share (or having a conversion price per share, if a security
     convertible into Preferred Shares or equivalent preferred shares) less than
     the then current per share market price of the Preferred Shares (as defined
     in Section 11(d)) on such record date, the Purchase Price to be in effect
     after such record date shall be determined by multiplying the Purchase
     Price in effect immediately prior to such record date by a fraction, the
     numerator of which shall be the number of Preferred Shares outstanding on
     such record date plus the number of Preferred Shares which the aggregate
     offering price of the total number of Preferred Shares and/or equivalent
     preferred shares so to be offered (and/or the aggregate initial conversion
     price of the convertible securities so to be offered) would purchase at
     such current market price and the denominator of which shall be the number
     of Preferred Shares outstanding on such record date plus the number of
     additional Preferred Shares and/or equivalent preferred shares to be
     offered for subscription or purchase (or into which the convertible
     securities so to be offered are initially convertible); provided, however,
                                                             --------  -------
     that in no event shall the consideration to be paid upon the exercise of
     one Right be less than the aggregate par value of the shares of capital
     stock of the Company issuable upon exercise of one Right.  In case such
     subscription price may be paid in a consideration part or all of which
     shall be in a form other than cash, the value of such consideration shall
     be as determined in good faith by the Board of Directors of the Company,
     whose determination shall be described

                                      -14-

<PAGE>

     in a statement filed with the Rights Agent.  Preferred Shares owned by or
     held for the account of the Company shall not be deemed outstanding for the
     purpose of any such computation.  Such adjustment shall be made
     successively whenever such a record date is fixed; and in the event that
     such rights, options or warrants are not so issued, the Purchase Price
     shall be adjusted to be the Purchase Price which would then be in effect if
     such record date had not been fixed.

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

          (d)  (i) For the purpose of any computation hereunder, the "current
     per share market price" of any security (a "Security" for the purpose of
     this Section 11(d)(i)) on any date shall be deemed to be the average of the
     daily closing price per share of such Security for the 30 consecutive
     Trading Days (as such term is hereinafter defined) immediately prior to
     such date; provided, however, that in the event
                --------  -------

                                      -15-

<PAGE>

     that the current per share market price of the Security is determined
     during a period following the announcement by the issuer of such Security
     of (A) a dividend or distribution on such Security payable in shares of
     such Security or securities convertible into such shares, or (B) any
     subdivision, combination or reclassification of such Security and prior to
     the expiration of 30 Trading Days after the ex-dividend date for such
     dividend or distribution, or the record date for such subdivision,
     combination or reclassification, then, and in each such case, the current
     per share market price shall be appropriately adjusted to reflect the
     current market price per share equivalent of such Security.  The
     closing price for each day shall be the last sale price, regular way, 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 or National Market System 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 or National Market System,
     the last quoted price or, if not so quoted, the average of the high bid and
     low asked prices in the over-the-counter market, as reported by the
     National Association of Securities Dealers, Inc. Automated Quotations
     System ("NASDAQ") or such other system then in use, or, if on any such date
     the Security is not quoted by any such organization, the average of the
     closing bid and asked prices as furnished by a professional market maker
     making a market in the Security selected by the Board of Directors of the
     Company.  The term "Trading Day" shall mean a day on which the principal
     national securities exchange on which the Security is listed or admitted to
     trading is open for the transaction of business or, if the Security is not
     listed or admitted to trading on any national securities exchange, a
     Business Day.

          (ii)  For the purpose of any computation hereunder, the "current per
     share market price" of the Preferred Shares shall be determined in
     accordance with the method set forth in Section 11(d)(i).  If the Preferred
     Shares are not publicly traded, the "current per share market price" of the
     Preferred Shares shall be conclusively deemed to be the current

                                      -16-

<PAGE>

     per share market price of the Common Shares as determined pursuant to
     Section 11(d)(i) (appropriately adjusted to reflect any stock split, stock
     dividend or similar transaction occurring after the date hereof),
     multiplied by one hundred.  If neither the Common Shares nor the Preferred
     Shares are publicly held or so listed or traded, "current per share market
     price" shall mean the fair value per share as determined in good faith by
     the Board of Directors of the Company, whose determination shall be
     described in a statement filed with the Rights Agent.

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

          (f)  If as a result of an adjustment made pursuant to Section 11(a)
     hereof, the holder of any Right thereafter exercised shall become entitled
     to receive any shares of capital stock of the Company other than Preferred
     Shares, thereafter the number of such other shares so receivable upon
     exercise of any Right shall be subject to adjustment from time to time in a
     manner and on terms as nearly equivalent as practicable to the provisions
     with respect to the Preferred Shares contained in Sections 11(a) through
     (c), 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.

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

                                      -17-

<PAGE>

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

          (i)  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-hundredths of a Preferred Share purchasable
     upon the exercise of a Right.  Each of the Rights outstanding after such
     adjustment of the number of Rights shall be exercisable for the number of
     one-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 one ten-thousandth) obtained by dividing the
     Purchase Price in effect immediately prior to adjustment of the Purchase
     Price by the Purchase Price in effect immediately after adjustment of the
     Purchase Price.  The Company shall make a public announcement of its
     election to adjust the number of Rights, indicating the record date for the
     adjustment, and, if known at the time, the amount of the adjustment to be
     made.  The record date may be the date on which the Purchase Price is
     adjusted or any day thereafter, but, if the Right Certificates have been
     issued, shall be at least 10 days later than the date of the public
     announcement.  If Right Certificates have been issued, upon each adjustment
     of the number of Rights pursuant to this Section 11(i), the Company shall,
     as promptly as practicable, cause to be distributed to holders of record of
     Right Certificates on such record date Right Certificates evidencing,
     subject to Section 14 hereof, the additional Rights to which such holders
     shall be entitled as a result of such adjustment, or, at the option of the
     Company, shall cause to be distributed to such holders of record in
     substitution and replacement for the Right Certificates held by such
     holders prior to the date

                                      -18-

<PAGE>

     of adjustment, and upon surrender thereof, if required by the Company, new
     Right Certificates evidencing all the Rights to which such holders shall be
     entitled after such adjustment.  Right Certificates so to be distributed
     shall be issued, executed and countersigned in the manner provided for
     herein and shall be registered in the names of the holders of record of
     Right Certificates on the record date specified in the public announcement.

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

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

          (l)  In any case in which this Section 11 shall require that an
     adjustment in the Purchase Price be made effective as of a record date for
     a specified event, the Company may elect to defer until the occurrence of
     such event the issuing to the holder of any Right exercised after such
     record date of the Preferred Shares and other capital stock or securities
     of the Company, if any, issuable upon such exercise over and above the
     Preferred Shares and other capital stock or securities of the Company, if
     any, issuable upon such exercise on the basis of the Purchase Price in
     effect prior to such adjustment; provided, however, that the Company shall
                                      --------  -------
     deliver to such holder a due bill or other appropriate instrument
     evidencing such holder's right to receive such additional shares upon the
     occurrence of the event requiring such adjustment.

          (m)  Anything in this Section 11 to the contrary notwithstanding, the
     Company shall be entitled to make such reductions in the Purchase Price, in
     addition to those adjustments expressly required by this Section 11, as and
     to the extent that it in its sole discretion shall determine to be
     advisable in

                                      -19-

<PAGE>

     order that any consolidation or subdivision of the Preferred Shares,
     issuance wholly for cash of any Preferred Shares at less than the current
     market price, issuance wholly for cash of Preferred Shares or securities
     which by their terms are convertible into or exchangeable for Preferred
     Shares, dividends on Preferred Shares payable in Preferred Shares or
     issuance of rights, options or warrants referred to hereinabove in Section
     11(b), hereafter made by the Company to holders of its Preferred Shares
     shall not be taxable to such stockholders.

          (n)  In the event that at any time on or after February 13, 1996 and
     prior to the Distribution Date, the Company shall (i) declare or pay any
     dividend on the Common Shares payable in Common Shares or (ii) effect a
     subdivision, combination or consolidation of the Common Shares (by
     reclassification or otherwise than by payment of dividends in Common
     Shares) into a greater or lesser number of Common Shares, then in any such
     case the number of Rights associated with each Common Share then
     outstanding, or issued or delivered thereafter but prior to the
     Distribution Date (or issuable thereafter at the discretion of the Board of
     Directors), 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(n) shall be made successively whenever such a dividend is
     declared or paid or such a subdivision, combination or consolidation is
     effected.

          Section 12.  Certificate of Adjusted Purchase Price or Number of
                       ---------------------------------------------------
Shares.  Whenever an adjustment is made as provided in Sections 11 and 13
- ------
hereof, the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with Section
25 hereof.

or indirectly, (a) the Company shall consolidate with, or merge with and into,
any other Person, (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 any other Person (or the Company) or cash or any other property,
or (c) the Company shall sell or otherwise transfer (or one or more of its
Subsidiaries shall sell or otherwise transfer), in one or more transactions,
assets or earning power aggregating 50% or more of the assets or earning power
of the Company and its Subsidiaries (taken as a whole) to any Person other than
the Company or one or more of its wholly owned Subsidiaries, then, and in each
such case (except as may be contemplated by the last sentence of this Section
13), proper provision shall be made so that (i) each holder of a Right (except
as otherwise provided herein) shall thereafter have the right to receive, upon
the exercise thereof at a price equal to the then current Purchase Price
multiplied by the number of one one-hundredths of a Preferred Share for which a
Right is then exercisable, in accordance with the terms of this Agreement and in
lieu of Preferred Shares, such number of Common Shares of such other Person
(including the Company as successor thereto or as the surviving corporation) as
shall equal the result obtained by (A) multiplying the then current Purchase
Price by the number of one one-hundredths of a Preferred Share for which a Right
is then exercisable and dividing that product by (B) 50% of the then current per
share market price of the Common Shares of such other Person (determined
pursuant to Section 11(d) hereof) on the date of consummation of such
consolidation, merger, sale or transfer; (ii) the issuer of such Common Shares
shall thereafter be liable for, and shall assume, by virtue of such
consolidation, merger, sale or transfer, all the obligations and duties of the
Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be
deemed to refer to such issuer; and (iv) such issuer shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
Common Shares in accordance with Section 9 hereof) in connection with such
consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to the
Common Shares thereafter deliverable upon the exercise of the Rights.  The
Company shall not consummate any such consolidation, merger, sale or transfer
unless prior thereto the Company and such issuer shall have executed and
delivered to the Rights Agent a supplemental agreement so providing.  The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits

                                      -21-

<PAGE>

intended to be afforded by the Rights.  The provisions of this Section 13 shall
similarly apply to successive mergers or consolidations or sales or other
transfers.

          Section 14.  Fractional Rights and Fractional Shares.
                       ---------------------------------------

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

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

                                      -22-

<PAGE>

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-hundredth of a Preferred Share,
the Company shall pay to the registered holders of Right Certificates at the
time such Rights are exercised as herein provided an amount in cash equal to the
same fraction of the current market value of one Preferred Share.  For the
purposes of this Section 14(b), the current market value of a Preferred Share
shall be the closing price of a Preferred Share (as determined pursuant to the
second sentence of Section 11(d)(i) hereof) for the Trading Day immediately
prior to the date of such exercise.

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

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

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

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

                                      -23-

<PAGE>

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

          (c)  the Company and the Rights Agent may deem and treat the person in
     whose name the Right Certificate (or, prior to the Distribution Date, the
     associated Common Shares certificate) is registered as the absolute owner
     thereof and of the Rights evidenced thereby (notwithstanding any notations
     of ownership or writing on the Right 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 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

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

                                      -24-

<PAGE>

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

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

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

          Section 20.  Duties of Rights Agent.  The Rights Agent undertakes the

duties and obligations imposed by this

                                      -25-

<PAGE>

Agreement upon the following terms and conditions, by all of which the Company
and the holders of Right Certificates, by their acceptance thereof, shall be
bound:

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

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

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

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

          (e)  The Rights Agent shall not be under any responsibility in respect
     of the validity of this Agreement or the execution and delivery hereof
     (except the due execution hereof by the Rights Agent) or in respect of the
     validity or execution of any Right Certificate (except its countersignature
     thereof); nor shall it be responsible for any breach by the Company of any
     covenant or condition contained in this Agreement or in any Right
     Certificate; nor shall it be responsible for any change in the
     exercisability of the Rights (including the Rights becoming void pursuant
     to Section 11(a)(ii) hereof) or any adjustment in the terms of the Rights
     (including the manner, method or amount thereof)

                                      -26-

     provided for in Section 3, 11, 13, 23 or 24, or the ascertaining of the
     existence of facts that would require any such change or adjustment (except
     with respect to the exercise of Rights evidenced by Right Certificates
     after actual notice that such change or adjustment is required); nor shall
     it by any act hereunder be deemed to make any representation or warranty as
     to the authorization or reservation of any Preferred Shares to be issued
     pursuant to this Agreement or any Right Certificate or as to whether any
     Preferred Shares will, when issued, be validly authorized and issued, fully
     paid and nonassessable.

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

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

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

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

     provided reasonable care was exercised in the selection and continued

          Section 21.  Change of Rights Agent.  The Rights Agent or any
                       ----------------------
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail.  The Company may remove the Rights Agent or any successor Rights Agent
upon 30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates by first-class mail.  If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent.  If the Company shall fail to make such
appointment within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Right Certificate
(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 California (or of any other state of the United States
so long as such corporation is authorized to do business as a banking
institution in the State of California), in good standing, having an office in
the State of California, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject to supervision or
examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $50
million.  After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose.  Not later than the effective
date of any such appointment the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Shares
or Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Right Certificates.  Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal

                                      -28-

of the Rights Agent or the appointment of the successor Rights Agent, as the
case may be.

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

          Section 23.  Redemption.
                       ----------

          (a)  The Board of Directors of the Company may, at its option, at any
time prior to such time as any Person becomes an Acquiring Person, redeem all
but not less than all the then outstanding Rights at a redemption price of $.001
per Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "Redemption Price").  The redemption of the
Rights by the Board of Directors may be made effective at such time, on such
basis and with such conditions as the Board of Directors in its sole discretion
may establish.

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

          Section 24.  Exchange.
                       --------

          (a)  The Board of Directors of the Company may, at its option, at any
time after any Person becomes an Acquiring Person, exchange all or part of the
then outstanding and exercisable Rights (which shall not include Rights that
have become void pursuant to the provisions of Section 11(a)(ii) hereof) for
Common Shares at an exchange ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such exchange ratio being hereinafter referred
to as the "Exchange Ratio").  Notwithstanding the foregoing, 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.

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

          (c)  In any exchange pursuant to this Section 24, the Company, at its
option, may substitute Preferred Shares (or equivalent preferred shares, as such
term is defined in Section 11(b) hereof) for Common Shares exchangeable for
Rights, at the initial rate of one one-hundredth of a Preferred Share (or
equivalent preferred share) for each Common Share, as appropriately adjusted to
reflect adjustments in the voting rights of the Preferred Shares pursuant to the
terms thereof, so that the fraction of a

                                      -30-

<PAGE>

Preferred Share delivered in lieu of each Common Share shall have the same
voting rights as one Common Share.

          (d)  In the event that there shall not be sufficient Common Shares or
Preferred Shares issued but not outstanding or authorized but unissued to permit
any exchange of Rights as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary to authorize additional
Common Shares or Preferred Shares for issuance upon exchange of the Rights.

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

          Section 25.  Notice of Certain Events.
                       ------------------------

          (a)  In case the Company shall propose (i) to pay any dividend payable
in stock of any class to the holders of its Preferred Shares or to make any
other distribution to the holders of its Preferred Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of its 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, (iii) to effect any reclassification of its Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, or

                                      -31-

<PAGE>

distribution of rights or warrants, or the date on which such reclassification,
consolidation, merger, sale, transfer, liquidation, dissolution or winding up is
to take place and the date of participation therein by the holders of the Common
Shares and/or Preferred Shares, if any such date is to be fixed, and such notice
shall be so given in the case of any action covered by clause (i) or (ii) above
at least 10 days prior to the record date for determining holders of the
Preferred Shares for purposes of such action, and in the case of any such other
action, at least 10 days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the Common Shares and/or
Preferred Shares, whichever shall be the earlier.

          (b)  In case any of the events set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate, in accordance with this Section 26, a notice
of the occurrence of such event, which notice shall describe such event and the
consequences of such event to holders of Rights under Section 11(a)(ii) hereof.

          Section 26.  Notices.  Notices or demands authorized by this Agreement
                       -------

                       --------------------------
time supplement or amend this Agreement without the approval of any holders of

which would adversely affect the interests of the holders of Rights.  Without
limiting the foregoing, the Company may at any time prior to such time as any

Shares then known by the Company to be beneficially owned by any Person (other

Common Shares).

               Corporation Law of the State of Delaware)

                    _____________________________


          Vivra Incorporated, a corporation organized and existing under the
laws 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(a) of the Delaware Corporation Law at
a meeting duly called and held on February 13, 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 Restated
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 600,000.  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.

                              A-1

<PAGE>

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

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

                             A-2

<PAGE>

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.

          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 or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

          (B)  Except as otherwise provided herein, in any other Certificate of
Designation creating a series of


                             A-3

<PAGE>

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

     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

          (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


                             A-4

<PAGE>

     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
Restated Certificate of Incorporation or in any other Certificate of Designation
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 or


                             A-5

<PAGE>

combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the proviso in clause
(1) of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

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

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

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

          Section 10.  Amendment.  The Restated 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


                             A-6

<PAGE>

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.

          IN WITNESS WHEREOF,  this Certificate of Designation has been executed
          ------------------

payment will be made, as provided in the Rights Agreement.

        No holder of this Right Certificate shall be entitled to vote or receive
dividends or be deemed for any purpose the holder of the Preferred Shares or of
any other securities of the Company which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein

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
