ITEM 1.  DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

     On November 12, 1998, the Board of Directors of Whittaker Corporation (the
"Company") declared a dividend of one preferred stock purchase right (a "Right")
for each outstanding share of common stock, par value $.01 per share (the
"Common Stock"), of the Company.  The dividend is payable on November 30, 1998
(the "Record Date") to holders of record as of the close of business on that
date.

     Prior to the Distribution Date (as defined below), the Rights will be
evidenced by the certificates for and will be transferred with the Common Stock,
and the registered holders of the Common Stock will be deemed to be the
registered holders of the Rights.  After the Distribution Date, the Rights Agent
will mail separate certificates evidencing the Rights to each record holder of
the Common Stock as of the close of business on the Distribution Date, and
thereafter the Rights will be transferable separately from the Common Stock.
The "Distribution Date" generally means the earlier of (i) the close of business
on the 10th day after the date (the "Stock Acquisition Date") of the first
public announcement that a person (other than the Company or any of its
subsidiaries or any employee benefit plan of the Company or any such subsidiary)
has acquired beneficial ownership of 25% or more of the outstanding shares of
Common Stock (an "Acquiring Person") and (ii) the close of business on the 10th
business day (or such later day as may be designated before any person has
become an Acquiring Person by the Board of Directors) after the date of the
commencement of a tender or exchange offer by any person which would, if
consummated, result in such person becoming an Acquiring Person.

     Prior to the Distribution Date, the Rights will not be exercisable to
purchase Series E Participating Cumulative Preferred Stock, par value $1.00 per
share (the "Preferred Stock").  After the Distribution Date, each Right will be
exercisable to purchase, for $125 (the "Purchase Price"), one one-hundredth of a
share of Preferred Stock.  The terms and conditions of the Rights are set forth
in a Rights Agreement dated as of November 12, 1998 between the Company and
Mellon Bank, N.A., as Rights Agent (the "Rights Agreement").

     At any time after any person has become an Acquiring Person (but before the
occurrence of any of the events described in the second succeeding paragraph),
each Right (other than Rights beneficially owned by the Acquiring Person and
certain affiliated persons) will entitle the holder to purchase, for the
Purchase Price, a number of shares of Common Stock having a market value of
twice the Purchase Price.

     At any time after any person has become an Acquiring Person (but before any
person becomes the beneficial owner of 50% or more of the outstanding shares of
Common Stock or the occurrence of any of the events described in the next
paragraph), the Board of Directors may exchange all or part of the Rights (other
than Rights beneficially owned by an Acquiring Person and certain affiliated
persons) for shares of Common Stock at an exchange ratio of one share of Common
Stock per Right.

     If, after any person has become an Acquiring Person, (1) the Company is
involved in a merger or other business combination in which the Company is not
the surviving corporation or its Common Stock is exchanged for other securities
or assets or (2) the Company and/or one or more of its subsidiaries sell or
otherwise transfer assets or earning power aggregating more than 50% of the
assets or earning power of the Company and its subsidiaries, taken as a whole,
then each Right (other than Rights beneficially owned by the Acquiring Person
and certain affiliated persons) will entitle the holder to purchase, for the
Purchase Price, a number of shares of common stock of the other party to such
business combination or sale (or in certain circumstances, an affiliate) having
a market value of twice the Purchase Price.

     The Board of Directors may redeem all of the Rights at a price of $.01 per
Right at any time before any person has become an Acquiring Person.

     The Rights will expire on November 30, 2008, unless earlier exchanged or
redeemed.

                                      -2-
<PAGE>
 
     For so long as the Rights are redeemable, the Rights Agreement may be
amended in any respect.  At any time when the Rights are no longer redeemable,
the Rights Agreement may be amended in any respect that does not adversely
affect Rights holders (other than any Acquiring Person and certain affiliated
persons), cause the Rights Agreement to become amendable other than in
accordance with this sentence or cause the Rights again to become redeemable.

     Rights holders have no rights as a stockholder of the Company, including
the right to vote and to receive dividends.

     The Rights Agreement includes antidilution provisions designed to prevent
efforts to diminish the effectiveness of the Rights.

     As of November 1, 1998 there were 11,345,199 shares of Common Stock
outstanding and 2,760,859 shares reserved for issuance under the Company's stock
option plans and for conversion of the Company's 7% convertible subordinated
note and the Company's Series D Participating Convertible Preferred Stock.  Each
outstanding share of Common Stock on the Record Date will receive one Right.
Shares of Common Stock issued after the Record Date and prior to the
Distribution Date will be issued with a Right attached so that all shares of
Common Stock outstanding prior to the Distribution Date will have Rights
attached.  150,000 shares of Preferred Stock have been reserved for issuance
upon exercise of the Rights.

     The Rights have certain anti-takeover effects.  The Rights may cause
substantial dilution to a person that attempts to acquire the Company without a
condition to such an offer that a substantial number of the Rights be acquired
or that the Rights be redeemed or declared invalid.  The Rights should not
interfere with any merger or other business combination approved by the Board of
Directors since the Rights may be redeemed by the Company as described above.

     While the dividend of the Rights will not be taxable to stockholders or to
the Company, stockholders or the Company may, depending upon the circumstances,
recognize taxable income in the event that the Rights become exercisable as set
forth above.

     The foregoing description of the Rights Agreement is qualified in its
entirety by reference to the full text of the Rights Agreement, which is
attached hereto as Exhibit 1 and incorporated herein by reference.

                                RIGHTS AGREEMENT

     AGREEMENT dated as of November 12, 1998, between Whittaker Corporation, a
Delaware corporation (the "COMPANY), and Mellon Bank, N.A., as Rights Agent (the
"RIGHTS AGENT").

 

                              W I T N E S S E T H

     WHEREAS, on November 12, 1998 the Board of Directors of the Company
authorized and declared a dividend of one preferred stock purchase right (a
"RIGHT") for each share of Common Stock (as hereinafter defined) outstanding at
the close of business on November 30, 1998 (the "RECORD DATE") and has
authorized the issuance, upon the terms and subject to the conditions
hereinafter set forth, of one Right (subject to adjustment) in respect of each
share of Common Stock issued after the Record Date, each Right representing the
right to purchase, upon the terms and subject to the conditions hereinafter set
forth, one one-hundredth (subject to adjustment) of a share of Preferred Stock
(as hereinafter defined);

     NOW, THEREFORE, the parties hereto agree as follows:

     Section 1.  Definitions.  The following terms, as used herein, have the
following meanings:

     "ACQUIRING PERSON" means any Person who, together with all Affiliates and
Associates of such Person, shall be the Beneficial Owner of 25% or more of the
shares of Common Stock then outstanding; provided, however, that an Acquiring
Person shall not include:

          (a)   any Person that the Board determines in good faith became the
     Beneficial Owner of shares of Common Stock that would otherwise cause such
     Person to be an "Acquiring Person" inadvertently (including, without
     limitation, because such Person was unaware of the extent of its Beneficial
     Ownership or was aware of the extent of its Beneficial Ownership but had no
     actual knowledge of the consequences of such Beneficial Ownership under
     this Agreement) and without any intention of changing or influencing
     control of the Company, unless and until such Person shall have failed to
     divest itself, as soon as practicable (as determined, in good faith, by the
     Board), of Beneficial Ownership of a sufficient number of shares of Common
     Stock so that such Person would no longer otherwise qualify as an
     "Acquiring Person";

                                       2
<PAGE>
 
          (b)  any Person who becomes the Beneficial Owner of shares of Common
     Stock that would otherwise cause such Person to be an Acquiring Person
     solely as a result of a repurchase of shares of Common Stock by the
     Company, unless and until such Person becomes the Beneficial Owner of any
     additional shares of Common Stock (other than pursuant to a dividend or
     distribution paid or made by the Company on the outstanding Common Stock or
     pursuant to a split or subdivision of the outstanding Common Stock) and at
     such time would be the Beneficial Owner of shares of Common Stock that
     would cause it to be an Acquiring Person; and

          (c)  any Exempt Person.

     "AFFILIATE" and "ASSOCIATE" have the respective meanings ascribed to such
terms in Rule 12b-2 under the Exchange Act as in effect on the date hereof.

     A Person shall be deemed the "BENEFICIAL OWNER" of, and shall be deemed to
have "BENEFICIAL OWNERSHIP" of and to "BENEFICIALLY OWN", any securities:

          (a)  which such Person or any of its Affiliates or Associates,
     directly or indirectly, beneficially owns (as determined pursuant to Rule
     13d-3 under the Exchange Act as in effect on the date hereof);


          (b)  which such Person or any of its Affiliates or Associates,
     directly or indirectly, has

                  (i)  the right to acquire (whether such right is exercisable
          immediately or only upon the occurrence of certain events or the
          passage of time or both) 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, warrants or options, or otherwise;
          provided, however, that a Person shall not be deemed the "Beneficial
          Owner" of, or to "beneficially own",  (A) 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, (B) securities which such Person
          has a right to acquire upon the exercise of Rights at any time prior
          to the time that any Person becomes an Acquiring Person or (C)
          securities issuable upon the exercise of Rights from and after the
          time that any Person becomes an Acquiring Person if such Rights were
          acquired by such Person or any of such Person's Affiliates or
          Associates prior to the

                                       3
<PAGE>
 
          Distribution Date or pursuant to Section 3(a) or Section 22 hereof
          ("ORIGINAL RIGHTS") or pursuant to Section 11(i) or Section 11(p) with
          respect to an adjustment to Original Rights; or

                  (ii)  the right to vote (whether such right is exercisable
          immediately or only upon the occurrence of certain events or the
          passage of time or both) pursuant to any agreement, arrangement or
          understanding (whether or not in writing) or otherwise; provided that
          a Person shall not be deemed the "Beneficial Owner" of or to
          "beneficially own" any security under this clause (ii) as a result of
          an agreement, arrangement or understanding to vote such security if
          such agreement, arrangement or understanding (A) arises solely from a
          revocable proxy or consent given in response to a public proxy or
          consent solicitation made pursuant to, and in accordance with, the
          applicable rules and regulations under the Exchange Act and (B) is not
          also then reportable by such Person on Schedule 13D under the Exchange
          Act (or any comparable or successor report); or

            (c)  which are beneficially owned, directly or indirectly, by any
     other Person (or any Affiliate or Associate thereof) and with respect to
     which such Person or any of its 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 pursuant to a revocable proxy or consent as described in
     subparagraph (b)(ii) immediately above) or disposing of any such
     securities;

provided, however, that no Person who is an officer, director or employee of an
Exempt Person shall be deemed, solely by reason of such Person's status or
authority as such, to be the "Beneficial Owner" of, to have "Beneficial
Ownership" of or to "beneficially own" any securities that are "beneficially
owned", including, without limitation, in a fiduciary capacity, by an Exempt
Person or by any other such officer, director or employee of an Exempt Person.

     "BOARD" means the Board of Directors of the Company.

     "BUSINESS DAY" means any day other than a Saturday, Sunday or a day on
which banking institutions in the State of New York are authorized or obligated
by law or executive order to close.

     "CLOSE OF BUSINESS" on any given date means 5:00 P.M., New York City time,
on such date; provided that if such date is not a Business Day "close of

                                       4
<PAGE>
 
business" means 5:00 P.M., New York City time, on the next succeeding Business
Day.

     "COMMON STOCK" means the Common Stock, par value $.01 per share, of the
Company, except that, when used with reference to any Person other than the

Acquiring Person or any Affiliate or Associate thereof), at the address of such
holder shown on the records of the Company, one or more Right Certificates
evidencing one Right (subject to adjustment as provided herein) for each share
of Common Stock so held.  If an adjustment in the number of Rights per share of
Common Stock has been made pursuant to Section 11, the Company shall, at the
time of distribution of the Right Certificates, make the necessary and
appropriate rounding adjustments (in accordance with Section 14(a)) so that
Right Certificates representing only whole numbers of Rights are distributed and
cash is paid in lieu of any fractional Rights.  From and after the Distribution
Date, the Rights will be evidenced solely by such Right Certificates.

          (c)  Rights shall be issued in respect of all shares of Common Stock
outstanding as of the Record Date or issued (on original issuance or out of
treasury) after the Record Date but prior to the earlier of the Distribution
Date and the Expiration Date.  In addition, in connection with the issuance or
sale of shares of Common Stock following the Distribution Date and prior to the
Expiration Date, the Company (i) shall, with respect to shares of Common Stock
so issued or sold (x) pursuant to the exercise of stock options or under any
employee plan or arrangement or (y) upon the exercise, conversion or exchange of
other securities issued by the Company prior to the Distribution Date and (ii)
may, in any other case, if deemed necessary or appropriate by the Board, issue
Right Certificates representing the appropriate number of Rights in connection
with such issuance or sale; provided that no such Right Certificate shall be
issued if, and to the extent that, (i) the Company shall be advised by counsel
that such issuance would create a significant risk of material adverse tax
consequences to the Company or the Person

                                       7
<PAGE>
 
to whom such Right Certificate would be issued or (ii) appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof.

          (d) Certificates issued for Common Stock after the Record Date but
prior to the earlier of the Distribution Date and the Expiration Date shall have
impressed on, printed on, written on or otherwise affixed to them the following
legend:

          This certificate also evidences certain Rights as set forth in a
          Rights Agreement between Whittaker Corporation and Mellon Bank, N.A.
          dated as of November 12, 1998 and as amended from time to time (the
          "RIGHTS AGREEMENT"), the terms of which are hereby incorporated herein
          by reference and a copy of which is on file at the principal executive
          offices of the Company. The Company will mail to the holder of this
          certificate a copy of the Rights Agreement without charge promptly
          after receipt of a written request therefor. Under certain
          circumstances, as set forth in the Rights Agreement, such Rights may
          be evidenced by separate certificates and no longer be evidenced by
          this certificate, may be redeemed or exchanged or may expire. AS SET
          FORTH IN THE RIGHTS AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY
          PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR AN AFFILIATE OR
          ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT),
          WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY
          SUBSEQUENT HOLDER, MAY BE NULL AND VOID.

          SECTION 4. Form of Right Certificates. The certificates evidencing the
Rights (and the forms of assignment, election to purchase and certificates to be
printed on the reverse thereof) (the "RIGHT CERTIFICATES") shall be
substantially in the form of 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, rule or regulation 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. The Right Certificates, whenever distributed, shall be dated as of the
Record Date.

          SECTION 5. Countersignature and Registration. (a) The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its President or any Vice President, either manually or by facsimile
signature, and shall have affixed thereto the Company's seal or a facsimile
thereof which shall be attested 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 so
                                       8
<PAGE>
 
countersigned.  In case any officer of the Company whose manual or facsimile
signature is affixed to 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 may, nevertheless, be
countersigned by the Rights Agent and issued and delivered 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.  Any Right Certificate may be signed
on behalf of the Company by any Person who, at the actual date of the execution
of such Right Certificate, shall be a proper officer of the Company to sign such
Right Certificate, although at the date of the execution of this Rights
Agreement any such Person was not such an officer.

       (b)  Following the Distribution Date, the Rights Agent will keep or cause
to be kept, at its principal office or offices designated as the place for
surrender of Right Certificates upon exercise, transfer or exchange, books for
registration and transfer of the Right Certificates.  Such books shall show with
respect to each Right Certificate the name and address of the registered holder
thereof, the number of Rights indicated on the certificate and the certificate
number.

       SECTION 6. Transfer and Exchange of Right Certificates; Mutilated,
Destroyed, Lost or Stolen Right Certificates. (a) At any time after the
Distribution Date and prior to the Expiration Date, any Right Certificate or
Certificates may, upon the terms and subject to the conditions set forth in this
Agreement, be transferred or exchanged for another Right Certificate or
Certificates evidencing a like number of Rights as the Right Certificate or
Certificates surrendered. Any registered holder desiring to transfer or exchange
any Right Certificate or Certificates shall surrender such Right Certificate or
Certificates (with, in the case of a transfer, the form of assignment and
certificate on the reverse side thereof duly executed) to the Rights Agent at
the principal office or offices of the Rights Agent designated for such purpose.
Neither the Rights Agent nor the Company shall be obligated to take any action
whatsoever with respect to the transfer of any such surrendered Right
Certificate or Certificates until the registered holder of the Rights has
complied with the requirements of Section 7(e). Upon satisfaction of the
foregoing requirements, the Rights Agent shall, subject to Sections 7(d), 14 and
24, countersign and deliver to the Person entitled thereto a Right Certificate
or Certificates as so requested. The Company may require payment of a sum
sufficient to cover any transfer tax or other governmental charge that may be
imposed in connection with any transfer or exchange of any Right Certificate or
Certificates.

       (b)  Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security

                                       9
<PAGE>
 
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 issue and deliver a new Right Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

       SECTION 7. Exercise of Rights; Purchase Price; Expiration Date of Rights.
(a) The registered holder of any Right Certificate may exercise the Rights
evidenced thereby (except as otherwise provided herein, including Sections 7(d),
7(e), 9(c), 11(a), 23 and 24) in whole or in part at any time after the
Distribution Date and prior to the Expiration Date upon surrender of the Right
Certificate, with the form of election to purchase and the certificate on the
reverse side thereof duly executed, to the Rights Agent at the principal office
or offices of the Rights Agent designated for such purpose, together with
payment (in lawful money of the United States of America by certified check or
bank draft payable to the order of the Company) of the aggregate Purchase Price
with respect to the Rights then to be exercised and an amount equal to any
applicable transfer tax or other governmental charge.

       (b)  Upon satisfaction of the requirements of Section 7(a) and subject to
Section 20(k), the Rights Agent shall thereupon promptly (i) (A) requisition
from any transfer agent of the Preferred Stock (or make available, if the Rights
Agent is the transfer agent therefor) certificates for the total number of one
one-hundredths of a share of Preferred Stock to be purchased (and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests) or (B) if the Company shall have elected to deposit the shares of
Preferred Stock issuable upon exercise of the Rights with a depositary agent,
requisition from the depositary agent depositary receipts representing interests
in such number of one one-hundredths of a share of Preferred Stock as are to be
purchased (in which case certificates for the shares of Preferred Stock
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company will direct the depositary agent to comply
with such request, (ii) requisition from the Company the amount of cash, if any,
to be paid in lieu of issuance of fractional shares in accordance with Section
14 and (iii) after receipt of such certificates or depositary receipts and cash,
if any, cause the same to be delivered to or upon the order of the registered
holder of such Right Certificate (with such certificates or receipts registered
in such name or names as may be designated by such holder).  If the Company is
obligated to deliver Common Stock, other securities or assets pursuant to this
Agreement, the Company will make all arrangements necessary so that such other
securities and assets are available for delivery by the Rights Agent, if and
when appropriate.

                                      10
<PAGE>
 
       (c)  In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing the number of Rights remaining unexercised shall be issued by the
Rights Agent and delivered to, or upon the order of, the registered holder of
such Right Certificate, registered in such name or names as may be designated by
such holder, subject to the provisions of Section 14.

       (d)  Notwithstanding anything in this Agreement to the contrary, from and
after the first occurrence of a Section 11(a)(ii) Event, any Rights beneficially
owned by (i) an Acquiring Person or an Associate or Affiliate of an Acquiring
Person, (ii) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person becomes such or
(iii) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee prior to or concurrently with the Acquiring
Person becoming such and receives such Rights pursuant to either (A) a transfer
(whether or not for consideration) from the Acquiring Person (or any such
Associate or Affiliate) to holders of equity interests in such Acquiring Person
(or in any such Associate or Affiliate) or to any Person with whom the Acquiring
Person (or any such Associate or Affiliate) has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which is part of a plan, arrangement or understanding which has as a primary
purpose or effect the avoidance of this Section 7(d) shall become null and void
without any further action, and no holder of such Rights shall have any rights
whatsoever with respect to such Rights, whether under any provision of this
Agreement or otherwise.  The Company shall use all reasonable efforts to insure
that the provisions of this Section 7(d) are complied with, but shall have no
liability to any holder of Right Certificates or other Person as a result of its
failure to make any determinations with respect to an Acquiring Person or its
Affiliates and Associates or any transferee of any of them hereunder.

       (e)  Notwithstanding anything in this Agreement to the contrary, neither
the Rights Agent nor the Company shall be obligated to undertake any action with
respect to a registered holder of Rights upon the occurrence of any purported
transfer pursuant to Section 6 or exercise pursuant to this Section 7 unless
such registered holder (i) shall have completed and signed the certificate
contained in the form of assignment or election to purchase, as the case may be,
set forth on the reverse side of the Right Certificate surrendered for such
transfer or exercise, as the case may be, (ii) shall not have indicated an
affirmative response to clause 1 or 2 thereof and (iii) shall have provided such
additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) or Affiliates or Associates thereof as the Company shall
reasonably request.

                                      11
<PAGE>
 
       SECTION 8. Cancellation and Destruction of Right Certificates. All Right
Certificates surrendered for exercise, transfer 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 this Agreement. The Company shall
deliver to the Rights Agent for cancellation, and the Rights Agent shall cancel,
any other Right Certificate purchased or acquired by the Company otherwise than
upon the exercise thereof. The Rights Agent shall deliver all cancelled Right
Certificates to the Company, or shall, at the written request of the Company,
destroy such cancelled Right Certificates, and in such case shall deliver a
certificate of destruction thereof to the Company.

       SECTION 9.  Reservation and Availability of Capital Stock. (a) The
Company covenants and agrees that it will cause to be reserved and kept
available a number of shares of Preferred Stock which are authorized but not
outstanding or otherwise reserved for issuance sufficient to permit the exercise
in full of all outstanding Rights as provided in this Agreement.

       (b)  So long as the Preferred Stock issuable upon the exercise of Rights
may be listed on any national securities exchange, the Company shall use its
best efforts to cause, from and after such time as the Rights become
exercisable, all securities reserved for such issuance to be listed on any such
exchange upon official notice of issuance upon such exercise.

       (c)  The Company shall use its best efforts (i) to file, as soon as
practicable following the earliest date after the occurrence of a Section
11(a)(ii) Event as of which the consideration to be delivered by the Company
upon exercise of the Rights has been determined in accordance with Section
11(a)(iii), or as soon as is required by law following the Distribution Date, as
the case may be, a registration statement under the Securities Act with respect
to the securities issuable upon exercise of the Rights, (ii) to cause such
registration statement to become effective as soon as practicable after such
filing and (iii) to cause such registration statement to remain effective (with
a prospectus at all times meeting the requirements of the Securities Act) until
the earlier of (A) the date as of which the Rights are no longer exercisable for
such securities and (B) the Expiration Date.  The Company will also take such
action as may be appropriate under, or to ensure compliance with, the securities
or blue sky laws of the various states in connection with the exercisability of
the Rights.  The Company may temporarily suspend, for a period of time not to
exceed 90 days after the date set forth in clause 9(c)(i), the exercisability of
the Rights in order to prepare and file such registration statement and permit
it to become effective.  Upon any such suspension, the Company shall issue a
public announcement stating that the

                                      12
<PAGE>
 
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect.
Notwithstanding any such provision of this Agreement to the contrary, the Rights
shall not be exercisable for securities in any jurisdiction if the requisite
qualification in such jurisdiction shall not have been obtained, such exercise
therefor shall not be permitted under applicable law or a registration statement
in respect of such securities shall not have been declared effective.

       (d)  The Company covenants and agrees that it will take all such action
as may be necessary to insure that all one one-hundredths of a share of
Preferred Stock issuable upon exercise of Rights shall, at the time of delivery
of the certificates for such securities (subject to payment of the Purchase
Price), be duly and validly authorized and issued and fully paid and
nonassessable.

       (e)  The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and other governmental
charges which may be payable in respect of the issuance or delivery of the Right
Certificates and of any certificates for Preferred Stock upon the exercise of
Rights. The Company shall not, however, be required to pay any transfer tax or
other governmental charge which may be payable in respect of any transfer
involved in the issuance or delivery of any Right Certificates or of any
certificates for Preferred Stock to a Person other than the registered holder of
the applicable Right Certificate, and prior to any such transfer, issuance or
delivery any such tax or other governmental charge shall have been paid by the
holder of such Right Certificate or it shall have been established to the
Company's satisfaction that no such tax or other governmental charge is due.

       SECTION 10.  Preferred Stock Record Date.  Each Person (other than the
Company) in whose name any certificate for Preferred Stock is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of such Preferred Stock 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 transfer taxes
or other governmental charges) was made; provided that if the date of such
surrender and payment is a date upon which the transfer books of the Company
relating to the Preferred Stock 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 applicable 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
stockholder of the Company with respect to shares for which the Rights shall be
exercisable, including the right to vote, to receive dividends or other
distributions or to

                                      13
<PAGE>
 
exercise any preemptive rights, and shall not be entitled to receive any notice
of any proceedings of the Company except as provided herein.

     SECTION 11.  Adjustment of Purchase Price, Number and Kind of Shares or
Number of Rights.

          (a)  (i)  If the Company shall at any time after the date of this
     Agreement (A) pay a dividend on the Preferred Stock payable in shares of
     Preferred Stock, (B) subdivide the outstanding Preferred Stock into a
     greater number of shares, (C) combine the outstanding Preferred Stock into
     a smaller number of shares or (D) issue any shares of its capital stock in
     a reclassification of the Preferred Stock (including any such
     reclassification in connection with a consolidation or merger involving the
     Company), the Purchase Price in effect immediately prior to the record date
     for such dividend or of the effective date of such subdivision, combination
     or reclassification, and the number and kind of shares of Preferred Stock
     or other capital stock issuable on such date shall be proportionately
     adjusted so that each holder of a Right shall (except as otherwise provided
     herein, including Section 7(d)) thereafter be entitled to receive, upon
     exercise thereof at the Purchase Price in effect immediately prior to such
     date, the aggregate number and kind of shares of Preferred Stock or other
     capital stock, as the case may be, which, if such Right had been exercised
     immediately prior to such date and at a time when the applicable transfer
     books of the Company were open, such holder would have been entitled to
     receive upon such exercise and by virtue of such dividend, subdivision,
     combination or reclassification.  If an event occurs which requires an
     adjustment under both this Section 11(a)(i) and Section 11(a)(ii), the
     adjustment provided for in this Section 11(a)(i) shall be in addition to,
     and shall be made prior to, any adjustment required pursuant to Section
     11(a)(ii).

            (ii)  If any Person, alone or together with its Affiliates and
     Associates, shall, at any time after the date of this Agreement, become an
     Acquiring Person, then each holder of a Right shall (except as otherwise
     provided herein, including Section 7(d)) thereafter be entitled to receive,
     upon exercise thereof at the Purchase Price in effect immediately prior to
     the first occurrence of a Section 11(a)(ii) Event, in lieu of Preferred
     Stock, such number of duly authorized, validly issued, fully paid and
     nonassessable shares of Common Stock of the Company (such shares being
     referred to herein as the "ADJUSTMENT SHARES") as shall be equal to the
     result obtained by dividing

                  (x) the product obtained by multiplying the Purchase Price in
          effect immediately prior to the first occurrence of a Section

                                      14
<PAGE>
 
          11(a)(ii) Event by the number of one one-hundredths of a share of
          Preferred Stock for which a Right was exercisable immediately prior to
          such first occurrence (such product being thereafter referred to as
          the "PURCHASE PRICE" for each Right) by

                  (y) 50% of the current market price (determined pursuant to
          Section 11(d)(i)) per share of Common Stock on the date of such first
          occurrence;

     provided, however, that the Purchase Price (as so adjusted pursuant to the
     foregoing clause (ii)(x)) and the number of Adjustment Shares so receivable
     upon exercise of a Right shall, following the occurrence of such Section
     11(a)(ii) Event, be subject to further adjustment as appropriate in
     accordance with Section 11(f).  From and after the occurrence of a Section
     13 Event, any Rights that theretofore have not been exercised pursuant to
     this Section 11(a)(ii) shall thereafter be exercisable only in accordance
     with Section 13 and not pursuant to this Section 11(a)(ii).

            (iii)   If the number of shares of Common Stock which are authorized
     by the Company's certificate of incorporation but not outstanding or
     reserved for issuance other than upon exercise of the Rights is not
     sufficient to permit the exercise in full of the Rights in accordance with
     Section 11(a)(ii), the Company shall, with respect to each Right, make
     adequate provision to substitute for the Adjustment Shares, upon payment of
     the Purchase Price then in effect, (A) (to the extent available) Common
     Stock and then, (B) (to the extent available) such number of one one-
     hundredths of a share of Preferred Stock as are then equivalent in value to
     the value of the Adjustment Shares, and then, if necessary, (C) other
     equity or debt securities of the Company, cash or other assets, a reduction
     in the Purchase Price or any combination of the foregoing, having an
     aggregate value (based upon the advice of a nationally recognized
     investment banking firm) equal to the value of the Adjustment Shares;
     provided that (x) the Company may, and (y) if the Company shall not have
     made adequate provision as required above to deliver value within 30 days
     following the first occurrence of a Section 11(a)(ii) Event (the
     "SUBSTITUTION PERIOD"), then the Company shall be obligated to deliver,
     upon the surrender for exercise of a Right and without requiring payment of
     the Purchase Price, (1) (to the extent available) Common Stock and then (2)
     (to the extent available) one-hundredths of a share of Preferred Stock and
     then, if necessary, (3)  other equity or debt securities of the Company,
     cash or other assets or any combination of the foregoing, having an
     aggregate value (based upon the advice of a nationally recognized
     investment banking firm) equal to the excess of the value of the Adjustment
     Shares over the

                                      15
<PAGE>
 
     Purchase Price. To the extent that the Company determines that some action
     is to be taken pursuant to the preceding sentence, the Company (X) shall
     provide, subject to Section 7(d), that such action shall apply uniformly to
     all outstanding Rights and (Y) may suspend the exercisability of the Rights
     until the expiration of the Substitution Period in order to decide the
     appropriate form and value of any consideration to be delivered as referred
     to in the preceding sentence. If any such suspension occurs, the Company
     shall issue a public announcement stating that the exercisability of the
     Rights has been temporarily suspended, as well as a public announcement at
     such time as the suspension is no longer in effect. For purposes of this
     Section 11(a)(iii), the value of the Common Stock shall be the current
     market price per share of Common Stock (as determined pursuant to Section
     11(d)) on the date of the first occurrence of a Section 11(a)(ii) Event;
     any common stock equivalent shall be deemed to have the same value as the
     Common Stock on such date; and the value of other securities or assets
     shall be determined pursuant to Section 11(d)(iii).

       (b)  In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Stock entitling them to
subscribe for or purchase (for a period expiring within 45 calendar days after
such record date) Preferred Stock (or securities having the same rights,
privileges and preferences as the shares of Preferred Stock ("EQUIVALENT
PREFERRED STOCK")) or securities convertible into or exercisable for Preferred
Stock (or equivalent preferred stock) at a price per share of Preferred Stock
(or equivalent preferred stock) (in each case, taking account of any conversion
or exercise price) less than the current market price (as determined pursuant to
Section 11(d)) per share of Preferred Stock on such record date, the Purchase
Price to be in effect after such record date shall be determined by multiplying
the Purchase Price in effect immediately prior to such date by a fraction, the
numerator of which shall be the number of shares of Preferred Stock outstanding
on such record date, plus the number of shares of Preferred Stock which the
aggregate price (taking account of any conversion or exercise price) of the
total number of shares of Preferred Stock (and/or equivalent preferred stock) so
to be offered would purchase at such current market price and the denominator of
which shall be the number of shares of Preferred Stock outstanding on such
record date plus the number of additional shares of Preferred Stock (and/or
equivalent preferred stock) so to be offered.  In case such subscription price
may be paid by delivery of 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, whose determination shall be described in a statement filed
with the Rights Agent and shall be conclusive for all purposes.  Shares of
Preferred Stock owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation.  Such adjustment
shall be made successively whenever such a record date is fixed, and if

                                      16
<PAGE>
 
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 Preferred Stock (including any such distribution
made in connection with a consolidation or merger involving the Company) of
evidences of indebtedness, equity securities other than Preferred Stock, assets
(other than a regular periodic cash dividend out of the earnings or retained
earnings of the Company) or rights, options or warrants (excluding those
referred to in Section 11(b)), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the current market price (as determined pursuant to Section 11(d)) per
share of Preferred Stock on such record date, less the value (as determined
pursuant to Section 11(d)(iii)) of such evidences of indebtedness, equity
securities, assets, rights, options or warrants so to be distributed with
respect to one share of Preferred Stock and the denominator of which shall be
such current market price per share of Preferred Stock.  Such adjustment shall
be made successively whenever such a record date is fixed, and if such
distribution is not so made, 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.

       (d)  (i)    For the purpose of any computation hereunder other than
computations made pursuant to Section 11(a)(iii) or 14, the "current market
price" per share of Common Stock on any date shall be deemed to be the average
of the daily closing prices per share of such Common Stock for the 30
consecutive Trading Days immediately prior to such date; for purposes of
computations made pursuant to Section 11(a)(iii), the "current market price" per
share of Common Stock on any date shall be deemed to be the average of the daily
closing prices per share of such Common Stock for the 10 consecutive Trading
Days immediately following such date; and for purposes of computations made
pursuant to Section 14, the "current market price" per share of Common Stock for
any Trading Day shall be deemed to be the closing price per share of Common
Stock for such Trading Day; provided that if the current market price per share
of the Common Stock is determined during a period following the announcement by
the issuer of such Common Stock of (A) a dividend or distribution on such Common
Stock payable in shares of such Common Stock or securities exercisable for or
convertible into shares of such Common Stock (other than the Rights), or (B) any
subdivision, combination or reclassification of such Common Stock, and prior to
the expiration of the requisite 30 Trading Day or 10 Trading Day period, as set
forth above, after the ex-dividend date for such dividend or distribution, or
the record date for such subdivision, combination or reclassification, then, and
in each

                                       17
<PAGE>
 
such case, the "current market price" shall be properly adjusted to take into
account ex-dividend trading. 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 shares of Common Stock are not listed or admitted to trading on the New
York Stock Exchange, on the principal national securities exchange on which the
shares of Common Stock are listed or admitted to trading or, if the shares of
Common Stock are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by the
National Association of Securities Dealers, Inc. Automated Quotation System
("NASDAQ") or such other system then in use or, if on any such date the shares
of Common Stock are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Common Stock selected by the Board. If on any such date no
market maker is making a market in the Common Stock, the fair value of such
shares on such date as determined in good faith by the Board (or, if at the time
of such determination there is an Acquiring Person, by a nationally recognized
investment banking firm) shall be used. If the Common Stock is not publicly held
or not so listed or traded, the "CURRENT MARKET PRICE" per share means the fair
value per share as determined in good faith by the Board, or, if at the time of
such determination there is an Acquiring Person, by a nationally recognized
investment banking firm, which determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes.

       (ii)   For the purpose of any computation hereunder, the "current
market price" per share of Preferred Stock shall be determined in the same
manner as set forth above for the Common Stock in Section 11(d)(i) (other than
the last sentence thereof). If the current market price per share of Preferred
Stock cannot be determined in such manner, the "current market price" per share
of Preferred Stock shall be conclusively deemed to be an amount equal to 100 (as
such number may be appropriately adjusted for such events as stock splits, stock
dividends and recapitalizations with respect to the Common Stock occurring after
the date of this Agreement) multiplied by the current market price per share of
Common Stock (as determined pursuant to Section 11(d)(i) (other than the last
sentence thereof)). If neither the Common Stock nor the Preferred Stock is
publicly held or so listed or traded, the "current market price" per share of
the Preferred Stock shall be determined in the same manner as set forth in the
last sentence of Section 11(d)(i). For all purposes of this Agreement, the
"current market price" of one one-hundredth of a share of Preferred Stock shall
be equal to the "current market price" of one share of Preferred Stock divided
by 100.

                                       18
<PAGE>
 
       (iii)  For the purpose of any computation hereunder, the value of
any securities or assets other than Common Stock or Preferred Stock shall be the
fair value as determined in good faith by the Board, or, if at the time of such
determination there is an Acquiring Person, by a nationally recognized
investment banking firm, which determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes.

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

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

       (g) All Rights originally issued by the Company subsequent to any
adjustment made hereunder shall evidence the right to purchase, at the Purchase
Price then in effect, the then applicable number of one one-hundredths of a
share of Preferred Stock and other capital stock of the Company issuable from
time to time hereunder upon exercise of the Rights, all subject to further
adjustment as provided herein.

       (h) Unless the Company shall have exercised its election as provided in
Section 11(i), upon each adjustment of the Purchase Price as a result of the
calculations made in Section 11(b) and 11(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 one-hundredths of a
share of Preferred Stock (calculated to the nearest one-millionth) obtained by
(iv) multiplying (x) the number of one one-hundredths of a share for which a
Right was exercisable immediately prior to this adjustment by (y) the Purchase
Price in effect immediately prior to such adjustment of the Purchase Price and
(v) dividing the

                                       19
<PAGE>
 
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 lieu of any adjustment in
the number of one one-hundredths of a share of Preferred Stock issuable upon the
exercise of a Right. Each of the Rights outstanding after such adjustment of the
number of Rights shall be exercisable for the number of one one-hundredths of a
share of Preferred Stock for which such Right was exercisable immediately prior
to such adjustment. Each Right held of record prior to such adjustment of the
number of Rights shall become that number of Rights (calculated to the nearest
ten-thousandth) obtained by dividing the Purchase Price in effect immediately
prior to adjustment of the Purchase Price by the Purchase Price in effect
immediately after adjustment of the Purchase Price. The Company shall make a
public announcement of its election to adjust the number of Rights, indicating
the record date for the adjustment, and, if known at the time, the amount of the
adjustment to be made. This record date may be the date on which the Purchase
Price is adjusted or any day thereafter, but, if the Right Certificates have
been issued, shall be at least 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, the additional Rights to which such holders shall be entitled as a
result of such adjustment, or, at the option of the Company, shall cause to be
distributed to such holders of record in substitution and replacement for the
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Right Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company, the adjusted Purchase Price) and shall be registered in the
names of the holders of record of Right Certificates on the record date
specified in the public announcement.

       (j) Irrespective of any adjustment or change in the Purchase Price or the
number of one one-hundredths of a share of Preferred Stock issuable upon the
exercise of the Rights, the Right Certificates theretofore and thereafter issued
may continue to express the Purchase Price per one one-hundredth of a share and
the number of shares 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 the par value, if any, of the number of one one-hundredths
of

                                       20
<PAGE>
 
a share of Preferred Stock issuable upon exercise of the Rights, the Company
shall take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable such number of one one-hundredths of a share of Preferred Stock at
such adjusted Purchase Price.

       (l) In any case in which this Section 11 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuance to the holder of any Right exercised after such record date the number
of one one-hundredths of a share of Preferred Stock or other capital stock of
the Company, if any, issuable upon such exercise over and above the number of
one one-hundredths of a share of Preferred Stock or other capital stock of the
Company, if any, issuable upon such exercise on the basis of the Purchase Price
in effect prior to such adjustment; provided 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
order that any consolidation or subdivision of the Preferred Stock, issuance
wholly for cash of any Preferred Stock at less than the current market price,
issuance wholly for cash of Preferred Stock or securities which by their terms
are convertible into or exercisable for Preferred Stock, stock dividends or
issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Company to the holders of its Preferred Stock, shall not
be taxable to such stockholders.

       (n) The Company covenants and agrees that it will not at any time after
the Distribution Date (i)  consolidate, merge or otherwise combine with or (ii)
sell or otherwise transfer (and/or permit any of its Subsidiaries to sell or
otherwise transfer), in one transaction or a series of related transactions,
assets or earning power aggregating more than 50% of the assets or earning power
of the Company and its Subsidiaries, taken as a whole, to any other Person or
Persons if (x) at the time of or immediately after such consolidation, merger,
combination or sale there are any rights, warrants or other instruments or
securities outstanding or any agreements or arrangements in effect which would
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights or (y) prior to, simultaneously with or immediately after
such consolidation, merger, combination or sale, the stockholders of a Person
who constitutes, or would constitute, the "Principal Party" for the purposes of
Section 13 shall have received

                                       21
<PAGE>
 
a distribution of Rights previously owned by such Person or any of its
Affiliates and Associates.

       (o) The Company covenants and agrees that after the Distribution Date, it
will not, except as permitted by Sections 23, 24 and 27, take (or permit any
Subsidiary to take) any action if at the time such action is taken it is
reasonably foreseeable that such action will substantially diminish or otherwise
eliminate the benefits intended to be afforded by the Rights.

       (p) Notwithstanding anything in this Agreement to the contrary, if at any
time after the date hereof and prior to the Distribution Date the Company shall
(i) pay a dividend on the outstanding shares of Common Stock payable in shares
of Common Stock, (ii)  subdivide the outstanding Common Stock into a larger
number of shares or (iii) combine the outstanding Common Stock into a smaller
number of shares, the number of Rights associated with each share of Common
Stock then outstanding, or issued or delivered thereafter as contemplated by
Section 3(c), shall be proportionately adjusted so that the number of Rights
thereafter associated with each share of Common Stock following any such event
shall equal the result obtained by multiplying the number of Rights associated
with each share of Common Stock immediately prior to such event by a fraction
the numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to the occurrence of the event and the denominator
of which shall be the total number of shares of Common Stock outstanding
immediately following the occurrence of such event.

  SECTION 12.  Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 and 13, the Company
shall (a) promptly prepare a certificate setting forth such adjustment and a
brief statement of the facts accounting for such adjustment, (b) promptly file
with the Rights Agent and with each transfer agent for the Preferred Stock and
the Common Stock a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Right Certificate (or, if prior to the Distribution Date, to
each holder of a certificate representing shares of Common Stock) in the manner
set forth in Section 26.  The Rights Agent shall be fully protected in relying
on any such certificate and on any adjustment therein contained.

  SECTION 13.  Consolidation, Merger or Sale or Transfer of Assets or Earning
Power.  (a)  If, following the occurrence of a Section 11(a)(ii) Event, directly
or indirectly,

            (x)  the Company shall consolidate with, merge into, or otherwise
     combine with, any other Person, and the Company shall not be the

                                       22
<PAGE>
 
     continuing or surviving corporation of such consolidation, merger or
     combination,

            (y) any Person shall merge into, or otherwise combine with, the
     Company, and the Company shall be the continuing or surviving corporation
     of such merger or combination and, in connection with such merger or
     combination, all or part of the outstanding shares of Common Stock shall be
     changed into or exchanged for other stock or securities of the Company or
     any other Person, cash or any other property, or

            (z) the Company and/or one or more of its Subsidiaries shall sell or
     otherwise transfer, in one transaction or a series of related transactions,
     assets or earning power aggregating more than 50% of the assets or earning
     power of the Company and its Subsidiaries, taken as a whole, to any other
     Person or Persons,

then, and in each such case, proper provision shall promptly be made so that

            (vi)  each holder of a Right shall thereafter be entitled to
     receive, upon exercise thereof at the Purchase Price in effect immediately
     prior to the first occurrence of a Section 11(a)(ii) Event, such number of
     duly authorized, validly issued, fully paid and nonassessable shares of
     freely tradeable Common Stock of the Principal Party (as hereinafter
     defined), not subject to any rights of call or first refusal, liens,
     encumbrances or other claims, as shall be equal to the result obtained by
     dividing


                  (A) the product obtained by multiplying the Purchase Price in
          effect immediately prior to the first occurrence of a Section
          11(a)(ii) Event by the number of one one-hundredths of a share of
          Preferred Stock for which a Right was exercisable immediately prior to
          such first occurrence (such product being thereafter referred to as
          the "PURCHASE PRICE" for each Right and for all purposes of this
          Agreement) by

                  (B)  50% of the current market price (determined pursuant to
          Section 11(d)(i)) per share of the Common Stock of such Principal
          Party on the date of consummation of such consolidation, merger,
          combination, sale or transfer;

provided, however, that the Purchase Price (as so adjusted pursuant to the
foregoing clause (i)(A)) and the number of shares of Common Stock of such
Principal Party so receivable upon exercise of a Right shall be subject to
further adjustment as appropriate in accordance with Section 11(f) to reflect
any events

                                       23
<PAGE>
 
occurring in respect of the Common Stock of such Principal Party after the
occurrence of such consolidation, merger, sale or transfer;

            (vii)  the Principal Party shall thereafter be liable for, and shall
     assume, by virtue of such consolidation, merger, combination, sale or
     transfer, all the obligations and duties of the Company pursuant to this
     Agreement;

            (viii) the term "COMPANY" shall thereafter be deemed to refer to
     such Principal Party, it being specifically intended that the provisions of
     Section 11 shall apply only to such Principal Party following the first
     occurrence of a Section 13 Event; and

            (ix)   such Principal Party shall take such steps (including the
     authorization and reservation of a sufficient number of shares of its
     Common Stock to permit exercise of all outstanding Rights in accordance
     with this Section 13(a)) in connection with the consummation of any such
     transaction as may be necessary to assure that the provisions hereof shall
     thereafter be applicable, as nearly as reasonably may be, in relation to
     the shares of its Common Stock thereafter deliverable upon the exercise of
     the Rights.

       (b)  "PRINCIPAL PARTY" means

            (i)    in the case of any transaction described in Section 13(a)(x)
     or (y), the Person that is the issuer of any securities into which shares
     of Common Stock of the Company are converted in such merger, consolidation
     or combination, and if no securities are so issued, the Person that
     survives or results from such merger, consolidation or combination; and

            (ii)   in the case of any transaction described in Section 13(a)(z),
     the Person that is the party receiving the greatest portion of the assets
     or earning power transferred pursuant to such transaction or transactions;

provided that in any such case, (A) if the Common Stock of such Person is not at
such time and has not been continuously over the preceding 12-month period
registered under Section 12 of the Exchange Act, and such Person is a direct or
indirect Subsidiary of another Person the Common Stock of which is and has been
so registered, "Principal Party" shall refer to such other Person; and (B) in
case such Person is a Subsidiary, directly or indirectly, of more than one
Person, the Common Stocks of two or more of which are and have been so
registered,

                                       24
<PAGE>
 
"Principal Party" shall refer to whichever of such Persons is the issuer of the
Common Stock having the greatest aggregate market value.

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

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

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

     SECTION 14.  Fractional Rights and Fractional Shares.  (a)  The Company
shall not be required to issue fractions of Rights, except prior to the
Distribution Date as provided in Section 11(p), or to distribute Right
Certificates which evidence fractional Rights.  In lieu of any such fractional
Rights, the Company shall pay 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
price of a whole Right.  For purposes of this Section 14(a), the current market
price of a whole Right shall be the closing price of a Right for the Trading Day
immediately prior to the date on which such fractional Rights would otherwise
have been issuable.  The closing price of a Right 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, 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

                                       25
<PAGE>
 
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. If on any such date no such market
maker is making a market in the Rights, the current market price of the Rights
on such date shall be as determined in good faith by the Board, or, if at the
time of such determination there is an Acquiring Person, by a nationally
recognized investment banking firm.

       (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are multiples of one one-hundredth
of a share of Preferred Stock) upon exercise of the Rights or to distribute
certificates which evidence fractional shares of Preferred Stock (other than
fractions which are multiples of one one-hundredth of a share of Preferred
Stock).  In lieu of any such fractional shares of Preferred Stock, 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 price of one one-hundredth of a share of
Preferred Stock.  For purposes of this Section 14(b), the current market price
of one one-hundredth of a share of Preferred Stock shall be one one-hundredth of
the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)) for the Trading Day immediately prior to the date of such
exercise.

       (c) Following the occurrence of any Triggering Event or upon any exchange
pursuant to Section 24, the Company shall not be required to issue fractions of
shares of Common Stock upon exercise of the Rights or to distribute certificates
which evidence fractional shares of Common Stock.  In lieu of fractional shares
of Common Stock, the Company shall pay to the registered holders of Right
Certificates at the time such Rights are exercised or exchanged as herein
provided an amount in cash equal to the same fraction of the current market
price of a share of Common Stock.  For purposes of this Section 14(c), the
current market price of a share of Common Stock shall be the closing price of a
share of Common Stock (as determined pursuant to Section 11(d)(i)) for the
Trading Day immediately prior to the date of such exercise or exchange.

       (d) 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 permitted by this Section 14.

     SECTION 15.  Rights of Action.   All rights of action in respect of this
Agreement are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of
certificates

                                       26

representing Common Stock); and any registered holder of any Right Certificate
(or, prior to the Distribution Date, of any certificate representing Common
Stock), without the consent of the Rights Agent or of the holder of any other
Right Certificate (or, prior to the Distribution Date, of any certificate
representing Common Stock), 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 Common Stock;


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

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

            (d) notwithstanding anything in this Agreement to the contrary,
     neither the Company nor the Rights Agent shall have any liability to any
     holder of a Right or other Person as a result of its inability to perform
     any of its obligations under this Agreement by reason of any preliminary or

                                       27
<PAGE>
 
     permanent injunction or other order, decree or ruling issued by a court of
     competent jurisdiction or by a governmental, regulatory or administrative
     agency or commission, or any statute, rule, regulation or executive order
     promulgated or enacted by any governmental authority prohibiting or
     otherwise restraining performance of such obligation; provided that the
     Company must use its best efforts to have any such order, decree or ruling
     lifted or otherwise overturned as soon as possible.

     SECTION 17.  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 shares of capital stock 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), 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.  (a)  The Company agrees to pay
to the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and disbursements and other disbursements incurred in
the execution or administration 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 loss, liability, or
expense, incurred without negligence, bad faith or willful misconduct on the
part of the Rights Agent, for anything done or omitted by the Rights Agent in
connection with the administration of this Agreement or the exercise or
performance of its duties hereunder, including the costs and expenses of
defending against any claim of liability.

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

     Section 19.  Merger or Consolidation or Change of Name of Rights Agents.
(a)  Any corporation into which the Rights Agent or any successor Rights Agent
may be merged or with which it may be consolidated, or any corporation resulting
from any merger or consolidation to which the Rights Agent or any successor
Rights Agent shall be a party, or any corporation succeeding to the corporate
trust or stock transfer 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.  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 a 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.

     (b) 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 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

                                       29
<PAGE>
 
     fact or matter (including, without limitation, the identity of any
     "Acquiring Person" and the determination of "current market price") be
     proved or established by the Company prior to taking, suffering or omitting
     to take any action hereunder, such fact or matter (unless other evidence in
     respect thereof be herein specifically prescribed) may be deemed to be
     conclusively proved and established by a certificate signed by the Chairman
     of the Board, the President or any Vice President and by the Treasurer or
     any Assistant Treasurer or the Secretary or any Assistant Secretary of the
     Company and delivered to the Rights Agent; and such certificate shall be
     full authorization to the Rights Agent for any action taken, suffered or
     omitted in good faith by it under the provisions of this Agreement in
     reliance upon such certificate.

          (c) The Rights Agent shall be liable hereunder only for its own
     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 7(d)) or any adjustment in the terms of the Rights (including
     the manner, method or amount thereof) provided for in Sections 3, 11, 13,
     23 or 24, or the ascertaining of the existence of facts that would require
     any such adjustment (except with respect to the exercise of Rights
     evidenced by Right Certificates after actual notice of any such
     adjustment); nor shall it by any act hereunder be deemed to make any
     representation or warranty as to the authorization or reservation of any
     shares of Common Stock or Preferred Stock to be issued pursuant to this
     Agreement or any Right Certificate or as to whether any shares of Common
     Stock or Preferred Stock will, when issued, be duly authorized, validly
     issued, fully paid and nonassessable.

                                       30

          (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
     the Chairman of the Board, the President or any Vice President or the
     Secretary or any Assistant Secretary or the Treasurer or any Assistant
     Treasurer of the Company, and to apply to such officers for advice or
     instructions in connection with its duties, and it shall not be liable for
     any action taken, suffered or omitted to be taken by it in good faith in
     accordance with instructions of any such officer.

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

          (i) The Rights Agent may execute and exercise any of the rights or
     powers hereby vested in it or perform any duty hereunder either itself or
     by or through its attorneys or agents, 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 or to any
     holders of Rights resulting from any such act, default, neglect or
     misconduct, provided that reasonable care was exercised in the selection
     and continued employment thereof.

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

          (k) If, with respect to any Right Certificate surrendered to the
     Rights Agent for exercise or transfer, the certificate attached to the form
     of

                                       31
<PAGE>
 
     assignment or form of election to purchase, as the cases may be, has either
     not been completed or indicates an affirmative response to clause 1 or 2
     thereof, the Rights Agent shall not take any further action with respect to
     such requested exercise or transfer without first consulting with the
     Company.

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

                                       32
<PAGE>
 
of the resignation or removal of the Rights Agent or the appointment of the
successor Rights Agent, as the case may be.

     Section 22.  Issuance of New Right Certificates.  Notwithstanding any of
the provisions of this 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 to reflect any adjustment or change in the
Purchase Price and the number or kind or class of shares of stock issuable upon
exercise of the Rights made in accordance with the provisions of this Agreement.

     Section 23.  Redemption.  (a)  The Board may, at its option, at any time
prior to the earlier of (x) the occurrence of a Section 11(a)(ii) Event and (xi)
the Final Expiration Date, redeem all but not less than all the then outstanding
Rights at a redemption price of $.01 per Right, as such amount may be
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "REDEMPTION PRICE").  The redemption of the
Rights may be made effective at such time, on such basis and with such
conditions as the Board in its sole discretion may establish.  The Redemption
Price shall be payable, at the option of the Company, in cash, shares of Common
Stock, or such other form of consideration as the Board shall determine.

     (b) Immediately upon the action of the Board electing to redeem the Rights
(or at such later time as the Board may establish for the effectiveness of such
redemption), and without any further action and without any notice, the right to
exercise the Rights will terminate and thereafter the only right of the holders
of Rights shall be to receive the Redemption Price for each Right so held. The
Company shall promptly thereafter give notice of such redemption to the Rights
Agent and the holders of the Rights in the manner set forth in Section 26;
provided that the failure to give, or any defect in, such notice shall not
affect the validity of such redemption. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of redemption will state the method by which the
payment of the Redemption Price will be made.

     Section 24.  Exchange.  (a)  At any time after the occurrence of a Section
11(a)(ii) Event, the Board may, at its option, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to Section 7(d)) for shares of Common Stock at an exchange
ratio of one share of Common Stock per Right, appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof (such exchange ratio being hereinafter referred to as the "EXCHANGE
RATIO").  Notwithstanding the foregoing, the Board shall not be empowered to
effect such exchange at any time after an Acquiring Person, together with all

                                       33
<PAGE>
 
Affiliates and Associates of such Acquiring Person, becomes the Beneficial Owner
of 50% or more of the shares of Common Stock then outstanding.  From and after
the occurrence of a Section 13 Event, any Rights that theretofore have not been
exchanged pursuant to this Section 24(a) shall thereafter be exercisable only in
accordance with Section 13 and may not be exchanged pursuant to this Section
24(a).  The exchange of the Rights by the Board may be made effective at such
time, on such basis and with such conditions as the Board in its sole discretion
may establish.

     (b) Immediately upon the effectiveness of the action of the Board electing
to exchange any Rights pursuant to Section 24(a) and without any further action
and without any notice, the right to exercise such Rights will terminate and
thereafter the only right of a holder of such Rights shall be to receive that
number of shares of Common Stock equal to the number of such Rights held by such
holder multiplied by the Exchange Ratio. The Company shall promptly thereafter
give notice of such exchange to the Rights Agent and the holders of the Rights
to be exchanged in the manner set forth in Section 26; provided that the failure
to give, or any defect in, such notice shall not affect the validity of such
exchange. 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 shares of Common
Stock 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 Section 7(d)) held by each holder of Rights.

     (c) The Company may at its option substitute, and, in the event that there
shall not be sufficient shares of Common Stock issued but not outstanding or
authorized but unissued to permit the exchange of Rights for Common Stock
ordered in accordance with Section 24(a), the Company shall substitute to the
extent of such insufficiency, for each share of Common Stock that would
otherwise be issuable upon exchange of a Right, a number of one one-hundredths
of a share of Preferred Stock such that the current market price (determined
pursuant to Section 11(d)) of such number of one-one hundredths of a share of
Preferred Stock is equal to the current market price (determined pursuant to
Section 11(d)) of one share of Common Stock as of the date of such exchange.

     Section 25.  Notice of Proposed Actions.  (a)  In case the Company shall
propose, at any time after the Distribution Date, (i) to pay any dividend
payable in stock of any class to the holders of Preferred Stock or to make any
other distribution to the holders of Preferred Stock (other than a regular
quarterly cash dividend out of earnings or retained earnings of the Company), or
(ii) to offer to the holders of its Preferred Stock rights or warrants to
subscribe for or to purchase 

                                       34
<PAGE>
 
any additional shares of Preferred Stock or shares of stock of any class or any
other securities, rights or options, or (iii) to effect any reclassification of
its Preferred Stock (other than a reclassification involving only the
subdivision or combination of outstanding shares of Preferred Stock) or (iv) to
effect any consolidation or merger with any other Person, or to effect and/or to
permit one or more of its Subsidiaries to effect any sale or other transfer, in
one transaction or a series of related transactions, of assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries, taken as a whole, to any other Person or Persons, or (v) to effect
the liquidation, dissolution or winding up of the Company, then, in each such
case, the Company shall give to each holder of a Right, to the extent feasible
and in accordance with Section 26, a notice of such proposed action, which shall
specify the record date for the purposes of any such dividend, distribution or
offering of rights or warrants, or the date on which any 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 Preferred
Stock, if any such date is to be fixed, and such notice shall be so given in the
case of any action covered by clause 25(a)(i) or 25(a)(ii) above at least 20
days prior to the record date for determining holders of the Preferred Stock
entitled to participate in such dividend, distribution or offering, and in the
case of any such other action, at least 20 days prior to the date of the taking
of such proposed action or the date of participation therein by the holders of
Preferred Stock, whichever shall be the earlier. The failure to give notice
required by this Section or any defect therein shall not affect the legality or
validity of the action taken by the Company or the vote upon any such action.

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

     (c) If a Triggering Event shall occur, then, in any such case, (i) the
Company shall as soon as practicable thereafter give to each holder of a Right,
in accordance with Section 26, a notice of the occurrence of such event, which
shall specify the event and the consequences of the event to holders of Rights
under Section 11(a)(ii) or 13, as the case may be, and (ii) all references in
Section 25(a) to Preferred Stock shall be deemed thereafter to refer to Common
Stock or other capital stock, as the case may be.

     Section 26.  Notices.  Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Right to or on the
Company shall be sufficiently given or made if sent by first-class mail (postage
prepaid) to the address of the Company indicated on the signature page hereof or

                                       35

such other address as the Company shall specify in writing to the Rights Agent.
Subject to the provisions of Section 21, any notice or demand authorized by this
Agreement to be given or made by the Company or by the holder of any Right to or
on the Rights Agent shall be sufficiently given or made if sent by first-class
mail (postage prepaid) to the address of the Rights Agent indicated on the
signature page hereof or such other address as the Rights Agent shall specify in
writing to the Company.  Notices or demands authorized by this Agreement to be
given or made by the Company or the Rights Agent to the holder of any Right
Certificate (or, prior to the Distribution Date, to the holder of any
certificate representing shares of Common Stock) shall be sufficiently given or
made if sent by first-class mail (postage prepaid) to the address of such holder
shown on the registry books of the Company.

     Section 27.  Supplements and Amendments.  For so long as the Rights are
redeemable, the Company may, and the Rights Agent shall if the Company so
directs, supplement or amend any provision of this Agreement in any respect
without the approval of any holders of certificates representing shares of
Common Stock.  At any time when the Rights are no longer redeemable, the Company
may, and the Rights Agent shall if the Company so directs, supplement or amend
this Agreement without the approval of any holders of Rights; provided, however,
that no such supplement or amendment may (a) adversely affect the interests of
the holders of Rights as such (other than an Acquiring Person or an Affiliate or
Associate of an Acquiring Person), (b) cause this Agreement again to become
amendable other than in accordance with this sentence, or (c) cause the Rights
again to become redeemable.  Upon the delivery of a certificate from an
appropriate officer of the Company which states that the proposed supplement or
amendment is in compliance with the terms of this Section, the Rights Agent
shall execute such supplement or amendment.

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

     Section 29.  Determinations and Actions by the Board, etc.  For all
purposes of this Agreement, any calculation of the number of shares of Common
Stock outstanding at any particular time, including for purposes of determining
the particular percentage of such outstanding shares of Common Stock of which
any Person is the Beneficial Owner, shall be made in accordance with the last
sentence of Rule 13d-3(d)(1)(i) under the Exchange Act as in effect on the date

                                PREFERRED STOCK

                                      OF

                             WHITTAKER CORPORATION

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


     We, Joseph F. Alibrandi, President and Chief Executive Officer, and Lynne
M. O. Brickner, Secretary, of Whittaker Corporation, a corporation organized and
existing under the General Corporation Law of the State of Delaware ("DELAWARE
LAW"), in accordance with the provisions thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by the
Certificate of Incorporation of the Corporation, the Board of Directors on
November 12, 1998, adopted the following resolution creating a series of
Preferred Stock in the amount and having the designation, voting powers,
preferences and relative, participating, optional and other special rights and
qualifications, limitations and restrictions thereof as follows:

     Section 1.  Designation and Number of Shares.  The shares of such series
shall be designated as "Series E Participating Cumulative Preferred Stock" (the
"SERIES E PREFERRED STOCK"), and the number of shares constituting such series
shall be 150,000.  Such number of shares of the Series E Preferred Stock may be
increased or decreased by resolution of the Board of Directors; provided that no
decrease shall reduce the number of shares of Series E Preferred Stock to a
number less than the number of shares then outstanding plus the number of shares
issuable upon exercise or conversion of outstanding rights, options or other
securities issued by the Corporation.

     Section 2.  Dividends and Distributions.

            (a)  The holders of shares of Series E Preferred Stock shall be
     entitled to receive, when, as and if declared by the Board of Directors out

                                      A-1
<PAGE>
 
     of funds legally available for the purpose, quarterly dividends payable in
     cash on January 30, April 30, July 30 and October 30 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 any share or fraction of a share of Series E Preferred Stock,
     in an amount per share (rounded to the nearest cent) equal to the greater
     of (i) $1.00 and (ii) subject to the provision for adjustment hereinafter
     set forth, 100 times the aggregate per share amount of all cash dividends
     or other distributions and 100 times the aggregate per share amount of all
     non-cash dividends or other distributions (other than (A) a dividend
     payable in shares of Common Stock, par value $.01 per share, of the
     Corporation (the "COMMON STOCK") or (B) 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 E
     Preferred Stock.  If the Corporation shall at any time after November 12,
     1998 (the "RIGHTS DECLARATION DATE") pay any dividend on Common Stock
     payable in shares of Common Stock or effect a subdivision or combination of
     the outstanding shares of Common Stock (by reclassification or otherwise)
     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 E Preferred Stock
     were entitled immediately prior to such event under clause 2(a)(ii) 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 E Preferred Stock as provided in paragraph 2(a) above immediately
     after it declares a dividend or distribution on the Common Stock (other
     than as described in clauses 2(a)(ii)(A) and 2(a)(ii)(B) above); provided
     that if 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 (or, with respect to the
     first Quarterly Dividend Payment Date, the period between the first
     issuance of any share or fraction of a share of Series E Preferred Stock
     and such first Quarterly Dividend Payment Date), a dividend of $1.00 per
     share on the Series E Preferred Stock shall nevertheless be payable on such
     subsequent Quarterly Dividend Payment Date.

                                      A-2
<PAGE>
 
          (c) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series E Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares of Series E Preferred
     Stock, unless the date of issue of such shares is on or before the record
     date for the first Quarterly Dividend Payment Date, in which case dividends
     on such shares shall begin to accrue and be cumulative from the date of
     issue of such shares, or unless the date of issue is a date after the
     record date for the determination of holders of shares of Series E
     Preferred Stock entitled to receive a quarterly dividend and on or before
     such Quarterly Dividend Payment Date, in which case 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
     shares of Series E 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 E Preferred Stock entitled to
     receive payment of a dividend or distribution declared thereon, which
     record date shall not be more than 60 days prior to the date fixed for the
     payment thereof.

     Section 3.  Voting Rights.  In addition to any other voting rights required
by law, the holders of shares of Series E Preferred Stock shall have the
following voting rights:

          (a) Subject to the provision for adjustment hereinafter set forth,
     each share of Series E Preferred Stock shall entitle the holder thereof to
     100 votes on all matters submitted to a vote of stockholders of the
     Corporation. If the Corporation shall at any time after the Rights
     Declaration Date pay any dividend on Common Stock payable in shares of
     Common Stock or effect a subdivision or combination of the outstanding
     shares of Common Stock (by reclassification or otherwise) 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 E 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 or by law, the holders of
     shares of Series E Preferred Stock and the holders of shares of Common

                                      A-3
<PAGE>
 
     Stock shall vote together as a single class on all matters submitted to a
     vote of stockholders of the Corporation.

          (c)  (i) If at any time dividends on any Series E Preferred Stock
     shall be in arrears in an amount equal to six quarterly dividends thereon,
     the occurrence of such contingency shall mark the beginning of a period
     (herein called a "DEFAULT PERIOD") which shall extend until such time when
     all accrued and unpaid dividends for all previous quarterly dividend
     periods and for the current quarterly dividend period on all shares of
     Series E Preferred Stock then outstanding shall have been declared and paid
     or set apart for payment.  During each default period, all holders of
     Preferred Stock and any other series of Preferred Stock then entitled as a
     class to elect directors, voting together as a single class, irrespective
     of series, shall have the right to elect two Directors.

               (ii)   During any default period, such voting right of the
          holders of Series E Preferred Stock may be exercised initially at a
          special meeting called pursuant to subparagraph 3(c)(iii) hereof or at
          any annual meeting of stockholders, and thereafter at annual meetings
          of stockholders; provided that neither such voting right nor the right
          of the holders of any other series of Preferred Stock, if any, to
          increase, in certain cases, the authorized number of Directors shall
          be exercised unless the holders of 10% in number of shares of
          Preferred Stock outstanding shall be present in person or by proxy.
          The absence of a quorum of holders of Common Stock shall not affect
          the exercise by holders of Preferred Stock of such voting right. At
          any meeting at which holders of Preferred Stock shall exercise such
          voting right initially during an existing default period, they shall
          have the right, voting as a class, to elect Directors to fill such
          vacancies, if any, in the Board of Directors as may then exist up to
          two Directors or, if such right is exercised at an annual meeting, to
          elect two Directors. If the number which may be so elected at any
          special meeting does not amount to the required number, the holders of
          the Preferred Stock shall have the right to make such increase in the
          number of Directors as shall be necessary to permit the election by
          them of the required number. After the holders of the Preferred Stock
          shall have exercised their right to elect Directors in any default
          period and during the continuance of such period, the number of
          Directors shall not be increased or decreased except by vote of the
          holders of Preferred Stock as herein provided or pursuant to the
          rights of any equity securities ranking senior to or pari passu with
          the Series E Preferred Stock.

                                      A-4
<PAGE>
 
               (iii)  Unless the holders of Preferred Stock shall, during an
          existing default period, have previously exercised their right to
          elect Directors, the Board of Directors may order, or any stockholder
          or stockholders owning in the aggregate not less than 10% of the total
          number of shares of Preferred Stock outstanding, irrespective of
          series, may request, the calling of special meeting of holders of
          Preferred Stock, which meeting shall thereupon be called by the
          President, a Vice President or the Secretary of the Corporation.
          Notice of such meeting and of any annual meeting at which holders of
          Preferred Stock are entitled to vote pursuant to this paragraph
          3(c)(iii) shall be given to each holder of record of Preferred Stock
          by mailing a copy of such notice to him at his last address as the
          same appears on the books of the Corporation.  Such meeting shall be
          called for a time not earlier than 20 days and not later than 60 days
          after such order or request or in default of the calling of such
          meeting within 60 days after such order or request, such meeting may
          be called on similar notice by any stockholder or stockholders owning
          in the aggregate not less than 10% of the total number of shares of
          Preferred Stock outstanding, irrespective of series.  Notwithstanding
          the provisions of this paragraph 3(c)(iii), no such special meeting
          shall be called during the period within 60 days immediately preceding
          the date fixed for the next annual meeting of stockholders.

               (iv)   In any default period, the holders of Common Stock, and
          other classes of stock of the Corporation if applicable, shall
          continue to be entitled to elect the whole number of Directors until
          the holders of Preferred Stock shall have exercised their right to
          elect two Directors voting as a class, after the exercise of which
          right (x) the Directors so elected by the holders of Preferred Stock
          shall continue in office until their successors shall have been
          elected by such holders or until the expiration of the default period,
          and (y) any vacancy in the Board of Directors may (except as provided
          in paragraph 3(c)(ii) hereof) be filled by vote of a majority of the
          remaining Directors theretofore elected by the holders of the class of
          stock which elected the Director whose office shall have become
          vacant.  References in this paragraph 3(c) to Directors elected by the
          holders of a particular class of stock shall include Directors elected
          by such Directors to fill vacancies as provided in clause (y) of the
          foregoing sentence.

               (v)    Immediately upon the expiration of a default period, (x)
          the right of the holders of Preferred Stock as a class to elect

                                      A-5
<PAGE>
 
          Directors shall cease, (y) the term of any Directors elected by the
          holders of Preferred Stock as a class shall terminate, and (z) the
          number of Directors shall be such number as may be provided for in the
          certificate of incorporation or bylaws irrespective of any increase
          made pursuant to the provisions of paragraph 3(c)(ii) hereof (such
          number being subject, however, to change thereafter in any manner
          provided by law or in the certificate of incorporation or bylaws).
          Any vacancies in the Board of Directors effected by the provisions of
          clauses (y) and (z) in the preceding sentence may be filled by a
          majority of the remaining Directors.

          (d) The Certificate of Incorporation of the Corporation shall not be
     amended in any manner (whether by merger or otherwise) so as to adversely
     affect the powers, preferences or special rights of the Series E Preferred
     Stock without the affirmative vote of the holders of a majority of the
     outstanding shares of Series E Preferred Stock, voting separately as a
     class.

          (e) Except as otherwise provided herein, holders of Series E Preferred
     Stock shall have no special voting rights, and their consent shall not be
     required for taking any corporate action.

     Section 4.  Certain Restrictions.

          (a) Whenever quarterly dividends or other dividends or distributions
     payable on the Series E 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 outstanding shares of Series E
     Preferred Stock shall have been paid in full, the Corporation shall not:

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

               (ii)   declare or pay dividends on, 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 E Preferred Stock, except dividends paid ratably on the Series
          E Preferred Stock and all such other 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;

                                      A-6
<PAGE>
 
               (iii)  redeem, purchase or otherwise acquire for value any shares
          of stock ranking junior (either as to dividends or upon liquidation,
          dissolution or winding up) to the Series E 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
          stock of the Corporation ranking junior (as to dividends and upon
          dissolution, liquidation or winding up) to the Series E Preferred
          Stock; or

               (iv)   redeem, purchase or otherwise acquire for value any
          shares of Series E Preferred Stock, or any shares of stock ranking on
          a parity (either as to dividends or upon liquidation, dissolution or
          winding up) with the Series E 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 Series E Preferred Stock
          and all such other parity stock 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 value any shares of stock of the
     Corporation unless the Corporation could, under paragraph 4(a), purchase or
     otherwise acquire such shares at such time and in such manner.

     Section 5.  Reacquired Shares.  Any shares of Series E Preferred Stock
redeemed, 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 without designation as to series and may be
reissued as part of a new series of Preferred Stock to be created by resolution
or resolutions of the Board of Directors as permitted by the Certificate of
Incorporation or as otherwise permitted under Delaware Law.

     Section 6.  Liquidation, Dissolution and 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 E Preferred Stock unless,
prior thereto, the holders of shares of Series E Preferred Stock shall have
received $1.00 per share, plus an amount equal to accrued and unpaid dividends
and 

                                      A-7
<PAGE>
 
distributions thereon, whether or not declared, to the date of such payment;
provided that the holders of shares of Series E 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 Common Stock, or (2) to the holders of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or
winding up) with the Series E Preferred Stock, except distributions made ratably
on the Series E Preferred Stock and all such other 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. If the Corporation shall at any time
after the Rights Declaration Date pay any dividend on Common Stock payable in
shares of Common Stock or effect a subdivision or combination of the outstanding
shares of Common Stock (by reclassification or otherwise) 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 E 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.  If 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 or any other property, then in any such case the shares of
Series E Preferred Stock shall at the same time be similarly exchanged for or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash or any other property, as the case may be, into which or for
which each share of Common Stock is changed or exchanged.  If the Corporation
shall at any time after the Rights Declaration Date pay any dividend on Common
Stock payable in shares of Common Stock or effect a subdivision or combination
of the outstanding shares of Common Stock (by reclassification or otherwise)
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 E 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

                               RIGHT CERTIFICATE

                             WHITTAKER CORPORATION

     This Right Certificate certifies that ______________________, or registered
assigns, is the registered holder of the number of Rights set forth above, each
of which entitles the holder (upon the terms and subject to the conditions set
forth in the Rights Agreement dated as of November 12, 1998 and as amended from
time to time (the "RIGHTS AGREEMENT") between Whittaker Corporation, a Delaware
corporation (the "COMPANY"), and Mellon Bank, N.A. (the "RIGHTS AGENT")) to
purchase from the Company, at any time after the Distribution Date and prior to
the Expiration Date, one one-hundredth of a fully paid, nonassessable share of
Series E Participating Cumulative Preferred Stock (the "SERIES E PREFERRED
STOCK") of the Company at a purchase price of $125 per one one-hundredth of a
share (the "PURCHASE PRICE"), payable in lawful money of the United States of
America, upon surrender of this Right Certificate, with the form of election to
purchase and related certificate duly executed, and payment of the Purchase
Price at an office of the Rights Agent designated for such purpose.

     Terms used herein and not otherwise defined herein have the meanings
assigned to them in the Rights Agreement.
<PAGE>
 
     The number of Rights evidenced by this Right Certificate (and the number
and kind of shares issuable upon exercise of each Right) and the Purchase Price
set forth above are as of ____________, ____, and may have been or in the future
be adjusted as a result of the occurrence of certain events, as more fully
provided in the Rights Agreement.

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

     This Right Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Right Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.

     Upon surrender at the principal office or offices of the Rights Agent
designated for such purpose and subject to the terms and conditions set forth in
the Rights Agreement, any Rights Certificate or Certificates may be transferred
or exchanged for another Rights Certificate or Certificates evidencing a like
number of Rights as the Rights Certificate or Certificates surrendered.

     Subject to the provisions of the Rights Agreement, the Board of Directors
of the Company may, at its option,

          (a) at any time prior to the earlier of (i) the occurrence of a
     Section 11(a)(ii) Event and (ii) the Final Expiration Date, redeem all but
     not less than all the then outstanding Rights at a redemption price of $.01
     per Right; or

          (b) at any time after any Person becomes an Acquiring Person (but
     before such Person becomes the Beneficial Owner of 50% or more of the
     shares of Common Stock then outstanding), exchange all or part of the then
     outstanding Rights (other than Rights held by the Acquiring Person

                                      B-2
<PAGE>
 
     and certain related Persons) for shares of Common Stock at an exchange
     ratio of one share of Common Stock per Right. If the Rights shall be
     exchanged in part, the holder of this Right Certificate shall be entitled
     to receive upon surrender hereof another Right Certificate or Certificates
     for the number of whole Rights not exchanged.

     No fractional shares of Series E Preferred Stock are required to be issued
upon the exercise of any Right or Rights evidenced hereby (other than fractions
which are integral multiples of one one-hundredth of a share of Series E
Preferred Stock, which may, at the election of the Company, be evidenced by
depositary receipts), but in lieu thereof a cash payment will be made, as
provided in the Rights Agreement.  If this Right Certificate shall be exercised
in part, the holder shall be entitled to receive upon surrender hereof another
Right Certificate or Certificates for the number of whole Rights not exercised.

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

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

                               Summary of Terms


FORM OF SECURITY     The Board has declared a dividend of one preferred stock
                     purchase right for each outstanding share of the Company's
                     Common Stock, payable to holders of record as of the close
                     of business on November 30, 1998 (each a "RIGHT" and
                     collectively, the "RIGHTS")

TRANSFER             Prior to the Distribution Date/1/, the Rights will be
                     evidenced by the certificates for and will be transferred
                     with the Common Stock, and the registered holders of the
                     Common Stock will be deemed to be the registered holders of
                     the Rights.

                     After the Distribution Date, the Rights Agent will mail
                     separate certificates evidencing the Rights to each record
                     holder of the Common Stock as of the

________________
     /1/ Distribution Date generally means the earlier of:
 
     (1)  the 10th day after public announcement that any person or group has
     become the beneficial owner of 25% or more of the Company's Common Stock;
     and
 
     (2)  the 10th business day after the date of the commencement of a tender
     or exchange offer by any person which would, if consummated, result in such
     person becoming the beneficial owner of 25% or more of the Company's Common
     Stock.
<PAGE>
 
                     close of business on the Distribution Date, and thereafter
                     the Rights will be transferable separately from the Common
                     Stock.

EXERCISE             Prior to the Distribution Date, the Rights will not be
                     exercisable.

                     After the Distribution Date but prior to the occurrence of
                     an event described below under "Flip-In" or "Flip-Over",
                     each Right will be exercisable to purchase, for $125 (the
                     "PURCHASE PRICE"), one one-hundredth of a share of Series E
                     Participating Cumulative Preferred Stock, par value $1.00
                     per share, of the Company.

FLIP-IN              Subject to certain exceptions, if any person or group (an
                     "ACQUIRING PERSON") becomes the beneficial owner of 25% or
                     more of the Company's Common Stock, then each Right (other
                     than Rights beneficially owned by the Acquiring Person and
                     certain affiliated persons) will entitle the holder to
                     purchase, for the Purchase Price, a number of shares of the
                     Company's Common Stock having a market value of twice the
                     Purchase Price.

FLIP-OVER            If, after any person has become an Acquiring Person, (1)
                     the Company is involved in a merger or other business
                     combination in which the Company is not the surviving
                     corporation or its Common Stock is exchanged for other
                     securities or assets or (2) the Company and/or one or more
                     of its subsidiaries sell or otherwise transfer assets or
                     earning power aggregating more than 50% of the assets or
                     earning power of the Company and its subsidiaries, taken as
                     a whole, then each Right will entitle the holder to
                     purchase, for the Purchase Price, a number of shares of
                     common stock of the other party to such business
                     combination or sale (or in certain circumstances, an
                     affiliate) having a market value of twice the Purchase
                     Price.

EXCHANGE             At any time after any person has become an Acquiring Person
                     (but before any person becomes 

                                      C-2
<PAGE>
 
                              the beneficial owner of 50% or more of the
                              Company's Common Stock), the Board may exchange
                              all or part of the Rights (other than the Rights
                              beneficially owned by the Acquiring Person and
                              certain affiliated persons) for shares of Common
                              Stock at an exchange ratio of one share of Common
                              Stock per Right.

REDEMPTION                    The Board may redeem all of the Rights at a price
                              of $.01 per Right at any time prior to the time
                              that any person becomes an Acquiring Person.

EXPIRATION                    The Rights will expire on November 30, 2008,
                              unless earlier exchanged or redeemed.

AMENDMENTS                    For so long as the Rights are redeemable, the
                              Rights Agreement may be amended in any respect.

                              At any time after the Rights are no longer
                              redeemable, the Rights Agreement may not be
                              amended in any respect that would adversely affect
                              the Rights holders (other than any Acquiring
                              Person and certain affiliated persons) or cause
                              the Rights again to become redeemable.

VOTING RIGHTS                 Rights holders have no rights as a stockholder of
                              the Company, including the right to vote and to
                              receive dividends.

ANTIDILUTION PROVISIONS       The Rights Agreement includes standard
                              antidilution provisions designed to protect the
                              efficacy of the Rights.

TAXES                         While the dividend of the Rights will not be
                              taxable to stockholders or to the Company,
                              stockholders or the Company may, depending upon
                              the circumstances, recognize taxable income in the
                              event that the Rights become exercisable as set
                              forth above.
