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

           Preferred Stock Purchase Rights
           -------------------------------

           On December 10, 1996, the Board of Directors of Cable Design
  Technologies Corporation (the "Company") authorized the issuance of one
  preferred share purchase right (a "Right") for each outstanding share of
  common stock, par value $.01 per share (the "Common Shares"), of the Company.
  The distribution is payable to the stockholders of record at the close of
  business on December 26, 1996 (the "Record Date"), and with respect to all
  Common Shares that become outstanding after the Record Date and prior to the
  earliest of the Distribution Date (as defined below), the redemption of the
  Rights, the exchange of the Rights, and the expiration of the Rights (and, in
  certain cases, following the Distribution Date).  Each Right entitles the
  registered holder to purchase from the Company one one-thousandth of a share
  of a Junior Participating Preferred Stock, Series A, par value $1.00 per
  share, of the Company (the "Preferred Shares") at a price of $150.00 per one
  one-thousandth of a Preferred Share (the "Purchase Price"), subject to
  adjustment.  The description and terms of the Rights are set forth in a Rights
  Agreement (the "Rights Agreement") between the Company and The First National
  Bank of Boston, as Rights Agent (the "Rights Agent").

            Until the earlier to occur of (i) the expiration of the Company's
  redemption rights following the date of public disclosure that a person or
  group other than certain exempt persons (an "Acquiring Person"), together with
  persons affiliated or associated with such Acquiring Person (other than those
  that are exempt persons), has acquired, or obtained the right to acquire,
  beneficial ownership of 20% or more of the outstanding Common Shares (the
  "Stock Acquisition Date") or (ii) the tenth business day after the date of
  commencement or public disclosure of an intention to commence a tender offer
  or exchange offer by a person other than an exempt person if, upon
  consummation of the offer, such person could acquire beneficial ownership of
  20% or more of the outstanding Common Shares (the earlier of such dates being
  called the "Distribution Date"), the Rights will be evidenced by Common Share
  certificates and not by separate certificates.  The Rights Agreement provides
  that, until the Distribution Date (or earlier redemption, exchange or
  expiration of the Rights), the Rights will be transferred with and only with
  the Common Shares.  Until the Distribution Date (or earlier redemption,
  exchange or expiration of the Rights), new Common Share certificates issued
  after December 26, 1996, upon transfer or new issuance of the Common Shares,
  will contain a notation incorporating the Rights Agreement by reference.
  Until the Distribution Date (or earlier redemption, exchange or expiration of
  the Rights) the surrender for transfer of any certificate for Common Shares,
  with or without such notation or a copy of this Summary of Rights being
  attached thereto, will also constitute the transfer of the Rights associated
  with the Common Shares represented by such certificate.  As soon as
  practicable following the Distribution Date, separate certificates evidencing
  the Rights ("Right Certificates") will be mailed to holders of record of the
  Common Shares as of the close of business on the Distribution Date, and such
  separate Right Certificates alone will evidence the Rights.

            The Rights will first become exercisable after the Distribution Date
  (unless sooner redeemed or exchanged).  The Rights will expire at the close of
  business on December 11, 2006 (the "Expiration Date"), unless earlier redeemed
  or exchanged by the Company as described below.

                                     - 2 -

            The Purchase Price payable, and the number of Preferred Shares or
  other securities, cash or other property issuable, upon exercise of the Rights
  are subject to adjustment from time to time to prevent dilution (i) in the
  event of a stock dividend or distribution on, or a subdivision, combination or
  reclassification of, the Preferred Shares, (ii) upon the grant to holders of
  the Preferred Shares of certain rights, options or warrants to subscribe for
  Preferred Shares or securities convertible into Preferred Shares at less than
  the current market price of the Preferred Shares or (iii) upon the
  distribution to holders of the Preferred Shares of evidences of indebtedness
  or assets (excluding regular periodic cash dividends out of earnings or
  retained earnings) or of subscription rights or warrants (other than those
  referred to above).  In addition, the Purchase Price payable and the number of
  Preferred Shares purchasable, on exercise of a Right is subject to adjustment
  in the event that the Company should (i) declare or pay any dividend on the
  Common Shares payable in Common Shares or (ii) effect a subdivision or
  combination of the Common Shares into a different number of Common Shares.

            In the event that a person becomes an Acquiring Person, proper
  provision shall be made so that each holder of a Right, other than Rights that
  are or were beneficially owned by the Acquiring Person and certain related
  persons and transferees (which will thereafter be void), shall thereafter have
  the right to receive upon exercise of such Right that number of Common Shares
  (or other securities) having at the time of such transaction a market value of
  two times the exercise price of the Right. In the event that a person becomes
  an Acquiring Person and the Company is involved in a merger or other business
  combination transaction where the Company is not the surviving corporation or
  where Common Stock is changed or exchanged or in a transaction or transactions
  in which 50% or more of its consolidated assets or earning power are sold,
  proper provision shall be made so that each holder of a Right (other than such
  Acquiring Person and certain related persons or transferees) shall thereafter
  have the right to receive, upon the exercise thereof at the then current
  exercise price of the Right, that number of shares of common stock of the
  acquiring company which at the time of such transaction would have a market
  value of two times the exercise price of the Right. In addition, the Company's
  Board of Directors has the option of exchanging all or part of the Rights
  (excluding void Rights) for an equal number of Common Shares in the manner
  described in the Rights Agreement.

            With certain exceptions, no adjustment in the Purchase Price will be
  required until cumulative adjustments require an adjustment of at least 1% in
  such Purchase Price.  No fractional Preferred Shares will be issued (other
  than fractions which are integral multiples of one one-thousandth of a
  Preferred Share, which may, at the election of the Company, be evidenced by
  depositary receipts) and in lieu thereof, an adjustment in cash will be made
  based on the market price of the Preferred Shares on the last trading date
  prior to the date of exercise.

            At any time prior to public disclosure that an Acquiring Person has
  become such, the Board of Directors of the Company may redeem the Rights in
  whole, but not in part, at a price of $.01 per Right (the "Redemption Price"),
  payable in cash, shares (including fractional shares) of Common Stock or any
  other form of consideration deemed appropriate by the Board of Directors.
  Immediately upon action of the Board of Directors ordering redemption of the
  Rights, the ability of holders to exercise the Rights will terminate and the
  only rights of such holders will be to receive the Redemption Price.

                                     - 3 -
<PAGE>
 
            At any time prior to a public disclosure that an Acquiring Person
  has become such, the Board of Directors of the Company may amend or supplement
  the Rights Agreement without the approval of the Rights Agent or any holder of
  the Rights, except for an amendment or supplement which would change the
  Redemption Price, provide for an earlier expiration date of the Rights or
  change the Purchase Price.  Thereafter, the Board of Directors of the Company
  may amend or supplement the Rights Agreement without such approval only to
  cure ambiguity, correct or supplement any defective or inconsistent provision
  or change or supplement the Rights Agreement in any manner which shall not
  adversely affect the interests of the holders of the Rights (other than an
  Acquiring Person or an affiliate or associate thereof).  Immediately upon the
  action of the Board of Directors providing for any amendment or supplement,
  such amendment or supplement will be deemed effective.

            The Preferred Shares purchasable upon exercise of the Rights will
  not be redeemable. Each Preferred Share will be entitled to a minimum
  preferential quarterly dividend payment equal to the greater of $25 per share
  and 1,000 times the dividend declared per Common Share.  In the event of
  liquidation, the holders of the Preferred Shares will be entitled to a minimum
  preferential liquidation payment equal to the greater of $100 per share and
  1,000 times the payment made per Common Share.  Each Preferred Share will have
  1,000 votes per share, voting together with the Common Shares.  In the event
  of any merger, consolidation or other transaction in which Common Shares are
  exchanged, each Preferred Share will be entitled to receive 1,000 times the
  amount received per Common Share.  These rights are protected by customary
  antidilution provisions.

            The Rights have certain anti-takeover effects.  The Rights may cause
  substantial dilution to a person or group other than an exempt person that
  attempts to acquire the Company on terms not approved by the Board, except
  pursuant to an offer conditioned on a substantial number of Rights being
  acquired.  The Rights should not interfere with any merger or other business
  combination approved by the Board of Directors prior to the time a person or
  group other than an exempt person has acquired beneficial ownership of 20% or
  more of the Common Shares, because until such time the Rights may generally be
  redeemed by the Company at $.01 per Right.

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

            This summary description of the Rights does not purport to be
  complete and is quali fied in its entirety by reference to the Rights
  Agreement attached as Exhibit 1.1, which is incorporated in this Registration
  Statement on Form 8-A by reference.

          Rights Agreement, dated as of December 11, 1996, between Cable Design
Technologies Corporation, a Delaware corporation (the "Company") and The First
                                                       -------                
National Bank of Boston, a national banking association (the "Rights Agent").
                                                              ------------   

                                    RECITALS
                                    --------

          The Board of Directors of the Company has authorized and declared the
payment of a dividend of one preferred share purchase right (the "Right") for
                                                                  -----      
each share of Common Stock (as defined in Section 1) outstanding on the Record
Date (as defined in Section 1) and has authorized the issuance of one Right for
each share of Common Stock issued between the Record Date and the Distribution
Date (as defined in Section 1) and in certain cases following the Distribution
Date. Each Right represents, as of the Record Date, the right to purchase one
one-thousandth (1/1000) of a share of Preferred Stock (as defined in Section 1)
upon the terms and subject to the conditions hereinafter set forth.

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

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

          (a) "Acquiring Person" means any Person who or which, together with
               ----------------                                              
all Affiliates and Associates of such Person, is (or has previously been, at any
time after the date of this Agreement, whether or not such Person(s) continues
to be) the Beneficial Owner of 20% or more of the Common Stock then outstanding
(determined without taking into account any securities exercisable or
exchangeable for, or convertible into, Common Stock, other than any such
securities beneficially owned by the Acquiring Person and Affiliates and
Associates of such Person). However, "Acquiring Person" shall not include any
Exempt Person.

          A Person does not become an "Acquiring Person" solely as the result of
(i) an acquisition of Common Stock by the Company which, by reducing the number
of shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to 20% more of the Common Stock then outstanding as
determined above, or (ii) such Person becoming the Beneficial Owner of 20% or
more of the Common Stock then outstanding as determined above solely as a result
of an Exempt Event; provided, however, that if a Person becomes the Beneficial
                    --------  -------                                         
Owner of 20% or more of the Common Stock then outstanding as determined above
solely by reason of such a share acquisition by the Company or the occurrence of
such an Exempt Event and such Person shall, after becoming the Beneficial Owner
of such Common Stock, become the Beneficial Owner of any additional shares of
Common Stock by any means whatsoever (other than as a result of the subsequent
occurrence of an Exempt Event, a stock dividend or a subdivision of the Common
Stock into a larger number of shares or a similar transaction), then such Person
shall be deemed to be an "Acquiring Person."

                                     - 1 -
<PAGE>
 
          No Person (including any Exempt Person) that would have become an
"Acquiring Person" solely on account of becoming the Beneficial Owner of
additional shares of Common Stock but would have become such inadvertently shall
become an Acquiring Person on such account if such Person divests sufficient
shares as soon as practicable so that the proportionate number of shares of
Common Stock beneficially owned by such Person is less than the level at which
such Person would otherwise have become an Acquiring Person.  The determination
of whether such Person's becoming an Acquiring Person would have been
inadvertent and the determination of whether the divestment of sufficient shares
has been made as soon as practicable shall be made by a majority of the Board of
Directors of the Company.

          (b) "Affiliate" of a Person has the meaning given to such term in Rule
               ---------                                                        
12b-2 of the General Rules and Regulations under the Exchange Act, as in effect
on the date of this Agreement; provided that, for purposes of this Agreement,
the term "Affiliate" shall not include any Person that is an Exempt Person.

          (c) "Associate" of a Person has the meaning given to such term in Rule
               ---------                                                        
12b-2 of the General Rules and Regulations under the Exchange Act, as in effect
on the date of this Agreement; provided that, for purposes of this Agreement,
the term "Associate" shall not include any Person that is an Exempt Person.

          (d) Except as provided below, a Person is the "Beneficial Owner" of,
                                                         ----------------
and "beneficially owns," any securities:
     ----------------

then any day for which the high bid and low asked prices in the over-the-counter
market are reported, or if the Common Stock, Preferred Stock or Equivalent
Shares are not traded in the over-the-counter market, then a Business Day.  If
the Common Stock, Preferred Stock or Equivalent Shares have not been so listed
or admitted to trading for 30 or more Trading Days or traded in the over-the-
counter market for 30 or more Trading Days, "Current Market Price"

the Company, other than the Preferred Stock, which is entitled to participate on
a proportional basis with the Preferred Stock in dividends and other

Equivalent Shares for purposes of Section 11, the number of shares, or fractions

same dividend or distribution as a whole share of Preferred Stock shall be

of Common Stock issued after the Record Date but prior to the earliest of the
Distribution Date, the Redemption Date, the Exchange Date and the Expiration
Date shall have impressed, printed, or written on, or otherwise affixed to them
a legend substantially in the following form:

          This certificate also evidences and entitles the holder hereof to
          certain Rights as set forth in a Rights Agreement between Cable Design
          Technologies Corporation and The First National Bank of Boston, as
          Rights Agent, dated as of December 11, 1996 (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 Cable
          Design Technologies Corporation.  Under certain circumstances, as set
          forth in the Rights Agreement, such Rights will be evidenced by
          separate certificates and will no longer be evidenced by this
          certificate.  Cable Design Technologies Corporation will mail to the
          holder of this certificate a copy of the Rights Agreement without
          charge after receipt of a written request therefor.  Under certain
          circumstances, Rights that were, are or become beneficially owned by
          Acquiring Persons or their Associates or Affiliates (as such terms are
          defined in the Rights Agreement) may become null and void and the
          holder of any of such Rights (including any subsequent holder) shall
          not have any right to exercise such Rights.

           Section 4.    Form of Rights Certificates.
                         --------------------------- 

          (a) The Rights Certificates (and the form of election to purchase
shares and form of assignment to be printed on the reverse thereof) shall be in
substantially 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
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any stock exchange on which the Rights may from time to time be
listed, or to conform to usage.  Subject to the provisions of this Agreement,
the Rights Certificates, whenever issued, shall be dated as of the Distribution
Date, and on their face shall entitle the holders thereof to purchase such
number of shares of Preferred Stock as shall be set forth therein at the
Purchase Price set forth therein, but the number of such securities and the
Purchase Price shall be subject to adjustment as provided in this Agreement.

          (b) Notwithstanding any other provision of this Agreement, (i) any
Rights Certificate issued pursuant to this Agreement that represents Rights
beneficially owned or formerly beneficially owned, on or after the earlier of
the Distribution Date and the Stock Acquisition Date, by a Person known by the
Company to be:  (A) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person; (B) a direct or indirect transferee of an Acquiring Person (or
of an Associate or Affiliate of such Acquiring Person) who becomes or becomes
entitled to be a transferee after the Acquiring Person becomes such; or (C) a
direct or indirect transferee of an Acquiring Person (or of an Associate or
Affiliate of such Acquiring Person) who becomes or becomes entitled to be a

                                     - 9 -
<PAGE>
 
transferee prior to or concurrently with the Acquiring Person becoming such and
receives such Rights pursuant to either (x) a direct or indirect transfer
(whether or not for consideration) from the Acquiring Person (or from an
Associate or Affiliate of such Acquiring Person) to holders of equity interests
in such Acquiring Person (or to holders of equity interests in an Associate or
Affiliate of such Acquiring Person) or to any Person with whom such Acquiring
Person (or an Associate or Affiliate of such Acquiring Person) has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (y) a direct or indirect transfer which a majority of the Board of
Directors of the Company has determined is part of a plan, arrangement or
understanding which has as a primary purpose or effect the avoidance of Section
7(e) of this Agreement, or (ii) any Rights Certificate issued pursuant to this
Agreement upon transfer, exchange, replacement or adjustment of any other Rights
Certificate beneficially owned by a Person referred to in this Section 4(b),
shall contain (to the extent feasible) the following legend:

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

           Section 5.    Execution, Countersignature and Registration.
                         -------------------------------------------- 

          (a) Each Rights Certificate shall be executed on behalf of the Company
by the Company's Chairman of the Board, Chief Executive Officer, President,
Chief Financial Officer 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 Company's Secretary or an Assistant
Secretary, either manually or by facsimile signature.  Each Rights Certificate
shall be countersigned by the Rights Agent either manually or, if permitted by
the Company, by facsimile signature and shall not be valid for any purpose
unless so countersigned.  In case any officer of the Company who shall have
signed a Rights Certificate shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Rights Certificate nevertheless may be countersigned by the Rights Agent
and issued and delivered with the same force and effect as though the Person who
signed such Rights Certificate had not ceased to be such officer of the Company;
and any Rights Certificate may be signed on behalf of the Company by any Person
who, at the actual date of the execution of such Rights Certificate, shall be a
proper officer of the Company to sign such Rights Certificate, although at the
date of the execution of this Agreement any such Person was not such an officer.

          (b) Following the Distribution Date, the Rights Agent shall keep or
cause to be kept, at its principal corporate trust office, books for
registration and transfer of the Rights Certificates issued hereunder.  Such
books shall show the names and addresses of the respective holders of the Rights
Certificates, the number of Rights evidenced by each Rights Certificate, and the
certificate number and the date of issuance of each Rights Certificate.

Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.
- - ---------------------------------------------------------------------- 

          (a) Subject to the provisions of Section 14, at any time after the
Close of Business on the Distribution Date and at or prior to the Close of
Business on the earliest of the Redemption Date, the Exchange Date and the
Expiration Date, any Rights Certificate or Rights Certificates may be
transferred, divided, combined or exchanged for another Rights Certificate or
Rights Certificates, entitling the registered holder to purchase a like number
of shares of Preferred Stock (or other securities, cash or other property,
following a Triggering Event or a Business Combination, as the case may be) as
the Rights Certificate or Rights Certificates surrendered then entitled such
holder to purchase.  Any registered holder desiring to transfer, divide, combine
or exchange any Rights Certificate shall make such request in writing delivered
to the Rights Agent, and shall surrender the Rights Certificate or Rights
Certificates to be transferred, divided, combined or exchanged at the principal
corporate office of the Rights Agent.  Thereupon the Rights Agent shall
countersign and deliver to the Person entitled thereto a Rights Certificate or
Rights Certificates, as the case may be, as so requested.  As a condition to
such transfer, division, combination or exchange, the Company may require
payment by the surrendering holder of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection therewith.  Neither the
Rights Agent nor the Company shall be obligated to take any action whatsoever
with respect to the transfer of any such surrendered Rights Certificate until
the registered holder shall have duly completed and executed the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
such former or proposed Beneficial Owner) thereof or such Beneficial Owner's
Affiliates or Associates as the Company shall reasonably request.

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

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

          (a) Each Right shall entitle (except as otherwise provided in this
Agreement) the registered holder thereof, upon the exercise thereof as provided
in this Agreement, to purchase, for the Purchase Price, at any time after the
Distribution Date and prior to the earliest of the Expiration Date, the Exchange
Date and the Redemption Date, one one-thousandth (1/1000) of a share of
Preferred Stock, subject to adjustment from time to time as provided in Sections
11 and 13.

          (b) The registered holder of any Rights Certificate may exercise the
Rights evidenced thereby (except as otherwise provided in this Agreement) in
whole or in part (except that no fraction of a Right may be exercised) at any
time after the Distribution Date and prior to the

                                     - 11 -
<PAGE>
 
earliest of the Expiration Date, the Exchange Date and the Redemption Date, by
surrendering the Rights Certificate, with the form of election to purchase on
the reverse side thereof duly executed, to the Rights Agent at the principal
corporate trust office of the Rights Agent, together with payment of the
Purchase Price for each one one-thousandth of a share of Preferred Stock (or
other securities, cash or other assets, as the case may be) as to which the
Rights are exercised.

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for each one one-thousandth of a share of
Preferred Stock (or, following a Triggering Event or a Business Combination,
other securities, cash or other assets, as the case may be) to be purchased and
an amount in cash, certified bank check or bank draft payable to the order of
the Company equal to any applicable transfer tax required to be paid by the
surrendering holder pursuant to Section 9(d), the Rights Agent shall, subject to
the provisions of this Agreement, thereupon promptly (i)(A) requisition from any
transfer agent for the Preferred Stock (or make available, if the Rights Agent
is the transfer agent for such shares) certificates for the total number of one
one-thousandths of a share of Preferred Stock (or other securities, as the case
may be) to be purchased (and the Company hereby irrevocably authorizes its
transfer agent to comply with all such requests), or (B) if the Company shall
have elected to deposit the total number of shares of Preferred Stock (or other
securities, as the case may be) issuable upon exercise of the Rights with a
depositary agent, requisition from the depositary agent depositary receipts
representing such number of one one-thousandths of a share of Preferred Stock
(or other securities, as the case may be) as are to be purchased (in which case
certificates for the Preferred Stock (or other securities, as the case may be)
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company shall direct the depositary agent to comply
with such request; (ii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder; and (iii) if appropriate, requisition from the
Company the amount of cash to be paid in lieu of issuance of fractional shares
in accordance with Section 14 of this Agreement and, promptly after receipt
thereof, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate.  In the event that the Company is obligated
to issue other securities (including shares of Common Stock) of the Company, pay
cash and/or distribute other property pursuant to this Agreement, the Company
will make all arrangements necessary so that such other securities, cash and/or
other property are available for distribution by the Rights Agent, if and when
appropriate.

          (d) In case the registered holder of any Rights Certificate shall
exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent and delivered to the registered holder of such Rights
Certificate or to his duly authorized assigns, subject to the provisions of
Section 6 and Section 14.

          (e) Notwithstanding anything in this Agreement to the contrary, any
Rights that are or were formerly beneficially owned on or after the earlier of
the Distribution Date or the Stock Acquisition Date by (i) an Acquiring Person
or any Associate or Affiliate of an Acquiring Person, (ii) a direct or indirect
transferee of an Acquiring Person (or of an Associate or Affiliate of such

                                     - 12 -
<PAGE>
 
Acquiring Person) who becomes or becomes entitled to be a transferee after the
Acquiring Person becomes such, or (iii) a direct or indirect transferee of an
Acquiring Person (or of an Associate or Affiliate of such Acquiring Person) who
becomes or becomes entitled to be a transferee prior to or concurrently with the
Acquiring Person becoming such and receives such Rights pursuant to either (A) a
direct or indirect transfer (whether or not for consideration) from the
Acquiring Person (or from an Associate or Affiliate of such Acquiring Person) to
holders of equity interests in such Acquiring Person (or to holders of equity
interests in any Associate or Affiliate of such Acquiring Person) or to any
Person with whom the Acquiring Person (or an Associate or Affiliate of such
Acquiring Person) has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a direct or indirect transfer which a
majority of the Board of Directors of the Company determines is part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of this Section 7(e), shall, immediately upon the occurrence of a
Triggering Event and without any further action, be null and void and no holder
of such Rights shall have any rights whatsoever with respect to such Rights
whether under this Agreement or otherwise, provided, however, that, in the case
of transferees under clause (ii) or clause (iii) above, any Rights beneficially
owned by such transferee shall be null and void only if and to the extent such
Rights were formerly beneficially owned by a Person who was, at the time such
Person beneficially owned such Rights, or who later became, an Acquiring Person
or an Affiliate or Associate of such Acquiring Person.  The Company shall use
all reasonable efforts to ensure that the provisions of this Section 7(e) and
Section 4(b) are complied with, but shall have no liability to any holder of a
Rights Certificate or to any other Person as a result of the Company's failure
to make, or any delay in making (including any such failure or delay by the
Board of Directors of the Company) any determinations with respect to an
Acquiring Person or its Affiliates, Associates or transferees hereunder.

          (f) 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 the registered holder of a Rights Certificate upon the
occurrence of any purported exercise as set forth in this Section 7 unless such
registered holder shall have (i) completed and signed the certificate contained
in the form of election to purchase set forth on the reverse side of the Rights
Certificate surrendered for such exercise and (ii) provided such additional
evidence of the identity of the Beneficial Owner (or former or proposed
Beneficial Owner) thereof or the Affiliates or Associates of such Beneficial
Owner (or former or proposed Beneficial Owner) as the Company shall reasonably
request.

          Section 8.     Cancellation and Destruction of Rights Certificates.
                         ---------------------------------------------------  
All Rights Certificates surrendered for the purpose of exercise, transfer,
division, combination or exchange shall, if surrendered to the Company or to any
of its agents, be delivered to the Rights Agent for cancellation or in canceled
form, or, if surrendered to the Rights Agent, shall be canceled by it, and no
Rights Certificates shall be issued in lieu thereof except as expressly
permitted by the provisions of this Agreement.  The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Rights Certificate purchased or acquired

                                     - 13 -
<PAGE>
 
by the Company otherwise than upon the exercise thereof.  The Rights Agent shall
deliver all canceled Rights Certificates to the Company, or shall, at the
written request of the Company, destroy such canceled Rights Certificates, and
in such case shall deliver a certificate of destruction thereof to the Company.

           Section 9.    Reservation and Availability of Preferred Stock.
                         ----------------------------------------------- 

          (a) The Company covenants and agrees that it will cause to be reserved
and kept available at all times out of its authorized and unissued shares of
Preferred Stock or its authorized and issued shares of Preferred Stock held in
its treasury (and, following the occurrence of a Triggering Event, out of its
authorized and unissued shares of Common Stock and/or other securities or out of
its authorized and issued shares of Common Stock and/or other securities held in
its treasury) free from preemptive rights or any right of first refusal, a
sufficient number of shares of Preferred Stock (and, following the occurrence of
a Triggering Event, shares of Common Stock and/or other securities) to permit
the exercise in full of all Rights from time to time outstanding.

          (b) The Company further covenants and agrees, so long as the Preferred
Stock (and, following the occurrence of a Triggering Event, shares of Common
Stock and/or other securities) issuable upon the exercise of Rights may be
listed on any United States national securities exchange, to use its best
efforts to cause, from and after the time that the Rights become exercisable,
all such shares and/or other securities reserved for such issuance to be listed
on such exchange upon official notice of issuance upon such exercise.

          (c) The Company further covenants and agrees that it will take all
such action as may be necessary to ensure that all shares of Preferred Stock
(and, following the occurrence of a Triggering Event or a Business Combination,
shares of Common Stock and/or other securities) delivered upon the exercise of
Rights shall, at the time of delivery of the certificates for such shares and/or
such other securities (subject to payment of the Purchase Price), be duly and
validly authorized and issued, fully paid, nonassessable, freely tradeable, not
subject to liens or encumbrances, and free of preemptive rights, rights of first
refusal or any other restrictions or limitations on the transfer or ownership
thereof, of any kind or nature whatsoever.

          (d) The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and charges which may
be payable in respect of the original issuance or delivery of the Rights
Certificates or of any certificates for shares of Preferred Stock (or Common
Stock and/or other securities, as the case may be) upon the exercise of Rights.
The Company shall not, however, be required to (i) pay any transfer tax which
may be payable in respect of any transfer involved in the issuance or delivery
of any Rights Certificates or the issuance or delivery of any certificates for
shares of Preferred Stock (or Common Stock and/or other securities as the case
may be) to a Person other than, or in a name other than that of, the registered
holder of the Rights Certificate evidencing Rights surrendered for exercise or
(ii) transfer or deliver any Rights Certificate or issue or deliver any
certificates for shares of Preferred Stock (or

                                     - 14 -
<PAGE>
 
Common Stock and/or other securities as the case may be) upon the exercise of
any Rights until any such tax shall have been paid (any such tax being payable
by the holder of such Rights Certificate at the time of surrender) or until it
has been established to the Company's satisfaction that no such tax is due.

          (e) The Company shall use its best efforts (i) as soon as practicable
following a Triggering Event (provided the consideration to be delivered by the
Company upon exercise of the Rights has been determined in accordance with
Section 11(a)(iii) of this Agreement), or as soon as is required by law
following the Distribution Date, as the case may be, to prepare and file a
registration statement on an appropriate form under the Securities Act with
respect to the securities purchasable 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 Rights are no longer exercisable
for such securities and (B) the Expiration Date.  The Company shall also use its
best efforts to take such action as may be necessary or appropriate under, or to
ensure compliance with, the securities or "blue sky" laws of the various states
in connection with the exercise of the Rights.  The Company may temporarily
suspend, for a period of time not to exceed 90 days after the date of a
Triggering Event described in clause (i) of the first sentence of this paragraph
of Section 9, 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 make 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.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained and until a registration statement
has been declared effective.

          Section 10.    Preferred Stock Record Date.  Each Person in whose name
                         ---------------------------                            
any certificate for shares of Preferred Stock (or Common Stock and/or other
securities, as the case may be) is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Stock (or Common Stock and/or other securities, as the case may be) represented
thereby on, and such certificate shall be dated, the date upon which the Rights
Certificate evidencing such Rights was duly surrendered and payment of the
Purchase Price (and any applicable transfer taxes) was made; provided, however,
                                                             --------  ------- 
that if the date of such surrender and payment is a date upon which the
Preferred Stock (or Common Stock and/or other securities, as the case may be)
transfer books of the Company are closed, such Person shall be deemed to have
become the record holder of such shares (and/or such other securities, as the
case may be) on, and such certificate shall be dated, the next succeeding
Business Day on which the Preferred Stock (or Common Stock and/or other
securities, as the case may be) transfer books of the Company are open.

and other property obtainable upon exercise of each Right and the number of
Rights outstanding shall be subject to adjustment from time to time as provided
in this Section 11.

          (a)  (i)  In the event the Company shall at any time on or after the
date of this Agreement (A) pay a dividend or make a distribution on the
Preferred Stock payable in shares of Preferred Stock, (B) subdivide (by a stock
split or otherwise) the outstanding Preferred Stock into a larger number of
shares, (C) combine (by a reverse stock split or otherwise) the outstanding
Preferred Stock into a smaller number of shares or (D) issue any securities in a
reclassification of the Preferred Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the surviving
corporation), then in each such event the Purchase Price and the Redemption
Price set forth in Section 23, as each is in effect at the time of the record
date for such dividend or distribution, or of the effective date of such
subdivision, combination or reclassification, shall be proportionately adjusted
by multiplying the Purchase Price and such Redemption Price by a fraction the
numerator of which shall be the total number of shares of Preferred Stock
outstanding immediately prior to the occurrence of such event and the
denominator of which shall be the total number of shares of Preferred Stock
outstanding immediately following the occurrence of such event.  If an event
occurs which would require an adjustment under both this Section 11(a)(i) and
Section 11(a)(ii), the adjustment provided for in this Section 11(a)(i) shall be
in addition to, and shall be made prior to, any adjustment required pursuant to
Section 11(a)(ii).

          (ii) Upon the first occurrence of a Triggering Event, proper provision
shall be made so that each holder of a Right, except as otherwise provided in
this Agreement, shall thereafter have the right to receive, and the Company
shall issue, upon exercise thereof at the then-current Purchase Price required
to be paid in order to exercise a Right in accordance with the terms of this
Agreement, in lieu of the number of one one-thousandths of a share of Preferred
Stock or other securities receivable upon exercise of a Right prior to the
occurrence of the Triggering Event, such number of shares of Common Stock of the
Company as shall equal the result obtained by (x) multiplying the then-current
Purchase Price by the number of one-thousandths of a share of Preferred Stock or
other securities for which a Right was then exercisable (without giving effect
to such Triggering Event) and (y) dividing that product by 50% of the Current
Market Price per share of Common Stock on the date of the occurrence of the
Triggering Event (such number of shares being referred to as the "Adjustment
                                                                  ----------

otherwise give rise to the foregoing adjustment is also subject to the
provisions of Section 13 of this Agreement, then only the provisions of Section
13 of this Agreement shall apply and no adjustment shall be made pursuant to
this Section 11(a)(ii).  Upon the occurrence of such Triggering Event, the
Purchase Price required to be paid in order to exercise a Right shall be
unchanged, and the Purchase Price shall be appropriately adjusted to reflect,
and shall thereafter mean, the amount required to be paid per share of Common
Stock upon exercise of a Right.

          (iii)     In lieu of issuing shares of Common Stock in accordance with
Section 11(a)(ii), the Company may, if a majority of the Board of Directors of
the Company determine that such action is necessary or appropriate and not
contrary to the interests of holders of Rights (and, in the event that the
number of shares of Common Stock which are authorized by the Company's
certificate of incorporation, but which are not outstanding or reserved for
issuance for purposes other than upon exercise of the Rights, are not sufficient
to permit the exercise in full of the Rights in accordance with Section
11(a)(ii), the Company shall) take one or more of the following actions:  (A)
reduce the Purchase Price required to be paid in order to exercise a Right by
any amount (the "Reduction Amount"), in which event the number of Adjustment

referred to as the "Total Consideration") shall be reduced so that the aggregate
                    -------------------                                         
value of the Total Consideration issuable in respect of each Right is equal to
the Current Value (as hereinafter defined) less the Reduction Amount (herein the
"Adjusted Current Value"), and/or (B) make adequate provision with respect to
 ----------------------                                                      
each Right to substitute for all or part of the Adjustment Shares otherwise
obtainable upon exercise of a Right:  (1) cash, (2) other equity securities of
the Company (including, without limitation, shares, or units of shares, of
preferred stock which a majority of the Board of Directors of the Company have
determined to have the same value as shares of Common Stock (such shares or
units of preferred stock being referred to as "Common Stock Equivalents")), (3)
                                               ------------------------        
debt securities of the Company, (4) other assets, or (5) any combination of the
foregoing (collectively, "Substitute Consideration"), having an aggregate value
                          ------------------------                             
which, when added to the value of the Adjustment Shares (if any) in respect of
which no substitution is being made, is equal to the Adjusted Current Value.  If
a majority of the Board of Directors of the Company determine to issue or
deliver any equity securities (other than Common Stock or Common Stock
Equivalents), debt securities and/or other assets pursuant to this Section
11(a)(iii), the value of such securities and/or assets shall be determined by a
majority of the Board of Directors of the Company based upon the advice of a
nationally recognized investment banking firm selected by a majority of the
Board of Directors of the Company.  If the Company is required to make adequate
provision to deliver value pursuant to the first sentence of this Section
11(a)(iii) and the Company shall not have made such adequate provision to
deliver value within ninety (90) days following the first occurrence of a
Triggering Event (the "Substitution Period"), then notwithstanding any provision
                       -------------------                                      
of Section 11(a)(ii) or this Section 11(a)(iii) to the contrary, the Company
shall be obligated to deliver, upon the surrender for exercise of a Right and
without requiring payment of the Purchase Price, shares of Common Stock (to the
extent available) and then, if necessary, cash, which shares and/or cash have an
aggregate value equal to the excess of the Current Value over the Purchase
Price.  If both Common Stock and cash are to be delivered pursuant to the
preceding sentence, amounts of both Common Stock and cash shall be delivered
upon surrender of each Right in a ratio of Common Stock to cash that bears the
same ratio as the total value of all Common Stock to be delivered (as determined
pursuant to this Section 11(a)(iii)) bears to the total value of all cash to be
delivered; provided, however, that the Company may adjust such ratio to avoid
           --------  -------                                                 
issuing any fractional shares of Common Stock so long as the method of
adjustment is applied consistently to each holder of Rights entitled to receive
value thereon pursuant to this Section 11(a)(iii).  To the extent that the
Company determines that some action is to be taken pursuant to the first and/or
third sentences of this Section 11(a)(iii), the Company (x) shall provide,
subject to Section 7(e) hereof, that such action shall apply uniformly to all
outstanding Rights, and (y) may suspend the exercisability of the Rights but in
no event to a time later than the expiration of the Substitution Period.  In the
event of any such suspension, the Company shall issue a public announcement
stating that the exercisability of the Rights has been temporarily suspended, as
well as a public announcement at such time as the suspension is no longer in
effect.  Upon any change in the Adjustment Shares obtainable upon exercise of a
Right pursuant to this Section 11(a)(iii), the Purchase Price shall thereafter
mean the amount, if any, required to be paid upon exercise of a Right for the
Adjustment Shares, if any, and the Substitute Consideration, if any, then
issuable or deliverable upon exercise of a Right, and a majority of the Board of
Directors of the Company shall make any necessary provisions to ensure that the
provisions of Section 11(e) shall thereafter apply

                                     - 17 -
<PAGE>
 
as appropriate to the Total Consideration.  For purposes of this Section
11(a)(iii), (A) "Current Value" shall be the product derived by multiplying (x)
                 -------------                                                 
the number of Adjustment Shares issuable in respect of each Right determined
under Section 11(a)(ii), by (y) the Current Market Price per share of Common
Stock on the date of the Triggering Event, and (B) the value of each share of
Common Stock and each share or unit of any "Common Stock Equivalent" shall be
                                            -----------------------          
deemed conclusively to be equal to the Current Market Price per share of the
Common Stock on the date of the Triggering Event.

          (iv)  A majority of the Board of Directors of the Company may, at
their option, at any time and from time to time after the first occurrence of a
Triggering Event, cause the Company to exchange, for all or part of the then-
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to the provisions of Section 7(e) hereof), shares of
Common Stock or Common Stock Equivalents 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 of this Agreement (such
exchange ratio being hereinafter referred to as the "Exchange Ratio").  Any
                                                     --------------        
partial exchange shall be effected on a pro rata basis based on the number of
Rights (other than Rights which have become void pursuant to the provisions of
Section 7(e) hereof) held by each holder of Rights.

          Immediately upon the action of a majority of the Board of Directors of
the Company ordering the exchange of any Rights pursuant to this Section
11(a)(iv) and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of shares of  Common Stock and/or
Common Stock Equivalents equal to the number of such Rights held by such holder
multiplied by the Exchange Ratio.  The Company shall promptly give public notice
of any such exchange and in addition, the Company shall promptly mail a notice
of any such exchange to all of the holders of such Rights in accordance with
Section 25 of this Agreement; provided, however, that the failure to give, any
                              --------  -------                               
delay in giving or any defect in, such notice shall not affect the validity of
such exchange.  Each such notice of exchange will state the method by which the
exchange of the Common Stock or Common Stock Equivalents for Rights will be
effected and, in the event of any partial exchange, the number of Rights which
will be exchanged.  In the event that the number of shares of  Common Stock
which is authorized but not outstanding or reserved for issuance for a purpose
other than exercise of the Rights is not sufficient to permit any exchange of
Rights as contemplated in accordance with this Section 11(a)(iv), the Board of
Directors of the Company shall take all such action within its power as may be
necessary to authorize additional shares of Common Stock for issuance upon
exchange of the Rights.  The Company shall not be required to issue fractions of
shares of Common Stock or Common Stock Equivalents or to distribute certificates
which evidence fractional shares of Common Stock or Common Stock Equivalents.
In lieu of such fractional shares of Common Stock or Common Stock Equivalents,
the Company shall pay to the registered holders of the Rights Certificates with
regard to which such fractional shares of Common Stock or Common Stock
Equivalents would otherwise be issuable an amount in cash equal to the product
derived by multiplying (x) the subject fraction, by (y) the last sale price of
the Company's Common Stock on the fifth Trading Day following the public
announcement of the exchange by the Company, or, in case no such sale takes
place on such day, the average of the high bid and low asked prices on such day,
in either case on a when issued basis (taking into account the exchange), as

                                     - 18 -
<PAGE>
 
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the NASDAQ (or, if the Company's
Common Stock is not so listed or traded, then as determined in the manner
provided under the definition of "Current Market Price," adjusted to take into
account the exchange).  For the purposes of this Section 11(a)(iv) the value of
any Common Stock Equivalent on any date shall be the same as the value of the
Common Stock, as determined pursuant to the previous sentence, on such date.

          (b) If the Company shall at any time on or after the date of this
Agreement fix a record date for the issuance of rights, options or warrants to
holders of Preferred Stock entitling them to subscribe for or purchase Preferred
Stock or Equivalent Shares (or securities convertible into Preferred Stock or
Equivalent Shares) at a price per share of Preferred Stock or Equivalent Shares
(or, in the case of a convertible security, having a conversion price per share
of Preferred Stock or Equivalent Shares) less than the Current Market Price per
share of Preferred Stock on such record date, the Purchase Price to be in effect
after such record date shall be determined by multiplying the Purchase Price in
effect immediately prior to such record date by a fraction, the numerator of
which shall be the number of shares of Preferred Stock and Equivalent Shares (if
any) outstanding on such record date, plus the number of shares of Preferred
Stock or Equivalent Shares, as the case may be, which the aggregate exercise
and/or conversion price for the total number of shares of Preferred Stock or
Equivalent Shares, as the case may be, which are obtainable upon exercise and/or
conversion of such rights, options, warrants or convertible securities would
purchase at such Current Market Price, and the denominator of which shall be the
number of shares of Preferred Stock and Equivalent Shares (if any) outstanding
on such record date, plus the number of additional shares of Preferred Stock or
Equivalent Shares, as the case may be, which may be obtained upon exercise
and/or conversion of such rights, options, warrants or convertible securities.
In case such subscription price may be paid in a consideration part or all of
which shall be in a form other than cash, the value of such consideration shall
be as determined in good faith by a majority of the Board of Directors of the
Company, whose determination shall be described in a statement filed with the
Rights Agent and shall be binding on the Rights Agent.  Preferred Stock and
Equivalent Shares owned by or held for the account of the Company or any
Subsidiary of the Company shall not be deemed outstanding for the purpose of any
such computation.  Such adjustment shall be made successively whenever such a
record date is fixed; and in the event that such rights, options or warrants are
not issued following such adjustment, the Purchase Price shall be readjusted to
be the Purchase Price which would have been in effect if such record date had
not been fixed.

          (c) In case the Company shall at any time after the date of this
Agreement fix a record date for the making of a distribution to holders of
Preferred Stock (including any such distribution made in connection with a
reclassification of the Preferred Stock or a consolidation or merger in which
the Company is the surviving corporation) of securities (other than Preferred
Stock and rights, options or warrants referred to in Section 11(b)), cash (other
than a regular periodic cash dividend at an annual rate not in excess of: (x)
125% of the annual rate of the regular cash dividend paid on the Preferred Stock
during the immediately preceding fiscal year (or, if the Preferred Stock was not
outstanding during such preceding fiscal year, then 125% of the annual rate of
the regular cash dividend paid on the Common Stock during such year), or (y) in
the event that a regular cash dividend was not paid on the Preferred Stock (or
Common Stock) during such preceding fiscal year, 5% of the Current Market Value
of the Preferred Stock on the date such regular cash dividend was

                                     - 19 -
<PAGE>
 
first declared), property, evidences of indebtedness or assets, the Purchase
Price to be in effect after such record date shall be determined by multiplying
the Purchase Price in effect immediately prior to such record date by a
fraction, the numerator of which shall be the Current Market Price per share of
Preferred Stock on such record date, less the fair market value (as determined
in good faith by a majority of the Board of Directors of the Company whose
determination shall be described in a statement filed with the Rights Agent) of
such securities, cash, property, evidences of indebtedness or assets to be so
distributed in respect of one share of Preferred Stock, and the denominator of
which shall be such Current Market Price per share of Preferred Stock on such
record date.  Such adjustments shall be made successively whenever such a record
date is fixed; and in the event that such distribution is not made following
such adjustment, the Purchase Price shall be readjusted to be the Purchase Price
which would have been in effect if such record date had not been fixed.

          (d) Except as provided below, no adjustment in the Purchase Price
shall be required unless such adjustment would require an increase or decrease
of at least 1% in the Purchase Price; provided, however, that any adjustments
                                      --------  -------                      
which by reason of this Section 11(d) 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, to the
nearest ten-thousandth of a share of Common Stock, or to the nearest ten-
millionth of a share of Preferred Stock, as the case may be.  Notwithstanding
the first sentence of this Section 11(d), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three years from the
date of the transaction which requires such adjustment or (ii) the Expiration
Date.

          (e) If, as a result of an adjustment made pursuant to Section 11(a) or
Section 13(a) of this Agreement, the holder of any Right thereafter exercised
shall become entitled to receive any securities of the Company other than shares
of Preferred Stock, thereafter the Purchase Price and the number of such other
securities so receivable upon exercise of any Right shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the shares of Preferred Stock
contained in this Section 11 and the provisions of Sections 7, 9, 10, 12, 13, 14
and 24 with respect to the shares of Preferred Stock shall apply on like terms
to any such other securities.

          (f) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of shares of Preferred
Stock or other securities, cash or other property purchasable from time to time
hereunder upon exercise of the Rights, all subject to further adjustment as
provided in this Agreement.

          (g) Unless the Company shall have exercised its election as provided
in Section 11(h), upon each adjustment of the Purchase Price as a result of the
calculations made in Sections 11(a)(i), 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-
thousandths of a share of Preferred Stock (calculated to the nearest one ten-
millionth of a share of Preferred Stock) obtained by (i) multiplying the number
of one one-thousandths of a share of Preferred Stock covered by a Right
immediately prior to adjustment pursuant to this Section 11(g) by the Purchase
Price in effect immediately prior to such adjustment

                                     - 20 -
<PAGE>
 
of the Purchase Price and (ii) dividing the product so obtained by the Purchase
Price in effect immediately after such adjustment of the Purchase Price.

          (h) The Company may elect, on or after the date of any adjustment of
the Purchase Price or any adjustment to the number of shares of Preferred Stock
for which a Right may be exercised, to adjust the number of Rights, in lieu of
an adjustment in the number of one one-thousandths of a share of Preferred Stock
purchasable upon the exercise of a Right.  Each of the Rights outstanding after
such adjustment of the number of Rights shall be exercisable for the number of
one one-thousandths of a share of Preferred Stock for which a Right was
exercisable immediately prior to such adjustment.  Each Right outstanding prior
to such adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one hundred-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to such adjustment by the Purchase
Price in effect immediately after such adjustment.  The Company shall make a
public announcement of its election to adjust the number of Rights, indicating
the record date for the adjustment, and, if known at the time, the amount of the
adjustment to be made.  This record date may be the date on which the Purchase
Price is adjusted or any day thereafter, but, if the Rights Certificates have
been issued, shall be at least 10 days after the date of the public
announcement.  If Rights Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Section 11(h) the Company shall, as
promptly as practicable, cause to be distributed to holders of record of Rights
Certificates on such record date a new Rights Certificate 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
Rights Certificates held by such holders prior to the date of adjustment and
upon surrender thereof (if required by the Company), new Rights Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment.  Rights Certificates to be so distributed shall be issued, executed
and countersigned in the manner provided for in this Agreement (and may bear, at
the option of the Company, the adjusted Purchase Price) and shall be registered
in the names of the holders of record of Rights Certificates on the record date
specified in the public announcement.

          (i) Irrespective of any adjustment or change in the Purchase Price or
the number or kind of shares issuable upon the exercise of the Rights, the
Rights Certificates theretofore and thereafter issued may continue to express
the Purchase Price per one one-thousandth of a share of Preferred Stock and the
number of shares of Preferred Stock which were expressed in the initial Rights
Certificates issued hereunder.

          (j) Before taking any action that would cause an adjustment reducing
the Purchase Price below the then par value, if any, of one one-thousandth of 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 one one-thousandth shares of such Preferred Stock at such adjusted
Purchase Price.

          (k) In any case in which this Section 11 shall require that an
adjustment 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

                                     - 21 -
<PAGE>
 
shares of Preferred Stock and other securities, cash or property of the Company,
if any, issuable upon such exercise over and above the shares of Preferred Stock
and other securities, cash or property of the Company, if any, issuable upon
such exercise on the basis of the Purchase Price in effect prior to such
adjustment; provided, however, that the Company shall deliver to such holder a
            --------  -------                                                 
due bill or other appropriate instrument evidencing such holder's right to
receive such additional shares (fractional or otherwise) or other securities,
cash or property upon the occurrence of the event requiring such adjustment.

          (l) 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 combination 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 exchangeable 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 holders of its Preferred Stock, shall not
be taxable to such stockholders.

          (m) The Company covenants and agrees that it shall not (i) consolidate
with, (ii) merge with or into or (iii) directly or indirectly sell, lease, or
otherwise transfer or dispose of (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 if (A) at the time of or immediately after such consolidation, merger,
sale, lease, transfer or disposition there are any rights, warrants, securities
or other instruments outstanding or agreements in effect which would
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights, (B) prior to, simultaneously with or immediately after
such consolidation, merger, sale, lease, transfer or disposition the
stockholders (or equity holders) of the Person who constitutes, or would
constitute, the Principal Party in such transaction shall have received a
distribution of Rights previously owned by such Person or any of its Affiliates
or Associates or (C) the form or nature of organization of the Principal Party
would preclude or limit the exercisability of the Rights.  The Company shall not
consummate any such consolidation, merger, sale, lease, transfer or disposition
unless prior thereto the Company and such other Person shall have executed and
delivered to the Rights Agent a supplemental agreement evidencing compliance
with this Section 11(m).

          (n) The Company covenants and agrees that, after the Stock Acquisition
Date it will not, except as permitted by Section 11(a)(iv), 26 or 29(b) of this
Agreement, 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,
directly or indirectly, diminish or otherwise eliminate the benefits intended to
be afforded by the Rights.

          (o) Anything in this Agreement to the contrary notwithstanding, if the
Company shall at any time prior to the Distribution Date (i) pay a dividend or
distribution on the outstanding shares of Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the
outstanding Common Stock into a smaller number of shares,

                                     - 22 -
<PAGE>
 
then the number of Rights associated with each share of Common Stock then
outstanding, or issued or delivered thereafter but prior to the Distribution
Date, and the Purchase Price under, and the number of one one-thousandths of a
share of Preferred Stock issuable in respect of, the Rights, shall be
proportionately adjusted, so that following such event one Right (with the
Purchase Price and the number of one one-thousandths of a share proportionately
adjusted thereunder) shall thereafter be associated with each share of Common
Stock then outstanding, or issued or delivered thereafter but prior to the
Distribution Date.  For example, if the Company effects a two-for-one stock
split at a time when each Right (if it becomes exercisable) would entitle the
holder to purchase one one-thousandth of a share of Preferred Stock for a
Purchase Price of $"Z", then following such stock split each previous Right
would be split into two current Rights and thereafter each current Right, upon
becoming exercisable, would (subject to further adjustment) entitle the holder
to purchase one two-thousandth of a share of Preferred Stock at a Purchase Price
of  1/2 x $"Z".

          Section 12.    Certification of Adjustments.  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 a copy of such certificate
and (c) mail a brief summary thereof to each holder of a Rights Certificate (or,
if no Rights Certificates have been issued, to each holder of a certificate
representing shares of Common Stock) in accordance with Section 25.
Notwithstanding the foregoing sentence, the failure of the Company to give such
notice shall not affect the validity of or the force or effect of or the
requirement for such adjustment.  Any adjustment to be made pursuant to Sections
11 and 13 of this Agreement shall be effective as of the date of the event
giving rise to such adjustment.

           Section 13.   Consolidation, Merger or Sale or Transfer of Assets or
                         ------------------------------------------------------

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

          (a) A "Business Combination" shall be deemed to occur in the event
that, in or following a Triggering Event, (i) the Company shall, directly or
indirectly, consolidate with, or merge with and into, any other Person (other
than a Subsidiary of the Company in a transaction that complies with Section
11(m) and Section 11(n) of this Agreement) in a transaction in which the Company
is not the continuing, resulting or surviving corporation of such merger or
consolidation, (ii) any Person (other than a Subsidiary of the Company in a
transaction that complies with Section 11(m) and Section 11(n) of this
Agreement) shall, directly or indirectly, consolidate with the Company, or shall
merge with and into the Company, in a transaction in which the Company is the
continuing, resulting  or surviving corporation of such merger or consolidation
and, in connection with such merger or consolidation, all or part of the Common
Stock shall be changed (including, without limitation, any conversion into or
exchange for securities of the Company or of any other Person, cash or any other
property), (iii) the Company shall, directly or indirectly, effect a share
exchange in which all or part of the Common Stock shall be changed (including,
without limitation, any conversion into or exchange for securities of any other
Person, cash or any other property) or (iv) the Company shall, directly or
indirectly, sell, lease, exchange, mortgage, pledge or otherwise transfer or
dispose of (or one or more of its Subsidiaries shall directly or indirectly
sell, lease, exchange, mortgage, pledge or otherwise transfer or dispose of), 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 (other than the

                                     - 23 -
<PAGE>
 
Company or any of its Subsidiaries in one or more transactions each and all of
which comply with Section 11(m) and Section 11(n) of this Agreement).

          In the event of a Business Combination, proper provision shall be made
so that each holder of a Right (except as otherwise provided in this Agreement)
shall thereafter have the right to receive, upon the exercise thereof at the
Purchase Price immediately prior to the first occurrence of a Triggering Event
multiplied by the number of one one-thousandths of a share of Preferred Stock
for which a Right was exercisable immediately prior to the first occurrence of a
Triggering Event (without giving effect to the Triggering Event) in accordance
with the terms of this Agreement, such number of shares of Common Stock of the
Principal Party as shall be equal to the result obtained by (x) multiplying the
Purchase Price immediately prior to the first occurrence of a Triggering Event
by the number of one one-thousandths of a share of Preferred Stock for which a
Right was exercisable immediately prior to the first occurrence of a Triggering
Event (without giving effect to the Triggering Event), and (y) dividing that
product by 50% of the Current Market Price per share of the Common Stock of such
Principal Party immediately prior to the consummation of such Business
Combination.  All shares of Common Stock of any Person for which any Right may
be exercised after consummation of a Business Combination as provided in this
Section 13(a) shall, when issued upon exercise thereof in accordance with this
Agreement, be duly and validly authorized and issued, fully paid, nonassessable,
freely tradeable, not subject to liens or encumbrances, and free of preemptive
rights, rights of first refusal or any other restrictions or limitations on the
transfer or ownership thereof of any kind or nature whatsoever.

          (b) After consummation of any Business Combination, (i) the Principal
Party shall be liable for, and shall assume, by virtue of such Business
Combination and without the necessity of any further act, all the obligations
and duties of the Company pursuant to this Agreement, (ii) the term "Company" as
used in this Agreement shall thereafter be deemed to refer to such Principal
Party and (iii) such Principal Party shall take all steps (including, but not
limited to, the reservation of a sufficient number of shares of its Common Stock
in accordance with Section 9) in connection with such Business Combination as
necessary to ensure that the provisions of this Agreement 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.

          (c) The Company shall not consummate any Business Combination unless
prior thereto (i) the Principal Party shall have a sufficient number of
authorized shares of its Common Stock which have not been issued or reserved for
issuance (other than shares reserved for issuance pursuant to this Agreement to
the holders of Rights) to permit the exercise in full of the Rights in
accordance with this Section 13, (ii) the Company and such Principal Party shall
have executed and delivered to the Rights Agent a supplemental agreement
providing for the fulfillment of the Principal Party's obligations and the terms
as set forth in paragraphs (a) and (b) of this Section 13 and further providing
that, as soon as practicable on or after the date of such Business Combination,
the Principal Party, at its own expense, shall (A) prepare and file, if
necessary, a registration statement on an appropriate form under the Securities
Act with respect to the Rights and the securities purchasable upon exercise of
the Rights, (B) use its best efforts to cause such registration statement to
become effective as soon as practicable after such filing and remain effective
(with a prospectus at all times meeting the requirements of the Securities Act)
until the Expiration Date, (C) deliver to

                                     - 24 -
<PAGE>
 
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 (or any successor form) under the Exchange Act, (D)
use its best efforts to qualify or register the Rights and the securities
purchasable upon exercise of the Rights under the state securities or "blue sky"
laws of such jurisdictions as may be necessary or appropriate, (E) use its best
efforts to list the Rights and the securities purchasable upon exercise of the
Rights on a United States national securities exchange and (F) obtain waivers of
any rights of first refusal or preemptive rights in respect of the Common Stock
of the Principal Party subject to purchase upon exercise of outstanding Rights,
(iii) the Company and the Principal Party shall have furnished to the Rights
Agent an opinion of independent counsel stating that such supplemental agreement
is a legal, valid and binding agreement of the Principal Party enforceable
against the Principal Party in accordance with its terms, and (iv) the Company
and the Principal Party shall have filed with the Rights Agent a certificate of
a nationally recognized firm of independent accountants setting forth the number
of shares of Common Stock of such issuer which may be purchased upon the
exercise of each Right after the consummation of such Business Combination.

          (d)  The provisions of this Section 13 shall similarly apply to
successive Business Combinations.  In the event a Business Combination shall be
consummated at any time after the occurrence of a Triggering Event, the Rights
which have not theretofore been exercised shall thereafter be exercisable for
the consideration and in the manner described in Section 13(a). Following a
Business Combination, the provisions of Section 11(a)(ii) of this Agreement
shall be of no effect.

          (e) Notwithstanding any other provision of this Agreement, no
adjustment to the number of shares of Preferred Stock (or fractions of a share)
or other securities, cash or other property for which a Right is exercisable or
the number of Rights outstanding or associated with each share of Common Stock
or any similar or other adjustment shall be made or be effective if such
adjustment would have the effect of reducing or limiting the benefits the
holders of the Rights would have had absent such adjustment, including, without
limitation, the benefits under Sections 11 and 13, unless the terms of this
Agreement are amended so as to preserve such benefits.

          (f) The Company covenants and agrees that it shall not effect any
Business Combination if at the time of, or immediately after such Business
Combination, there are any rights, options, warrants or other instruments
outstanding which would diminish or otherwise eliminate the benefits intended to
be afforded by the Rights.

          (g) Without limiting the generality of this Section 13, in the event
the nature of the organization of any Principal Party shall preclude or limit
the acquisition of Common Stock of such Principal Party upon exercise of the
Rights as required by Section 13(a) as a result of a Business Combination, it
shall be a condition to such Business Combination that such Principal Party
shall take such steps (including, but not limited to, a reorganization) as may
be necessary to ensure that the benefits intended to be derived under this
Section 13 upon the exercise of the Rights are assured to the holders thereof.

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

                                     - 25 -
<PAGE>
 
          (a) The Company shall not be required to issue fractional Rights or to
distribute Rights Certificates which evidence fractional Rights.  In lieu of
such fractional Rights, the Company may at its option pay to the registered
holders of the Rights Certificates with respect to which such fractional Rights
would otherwise be issuable an amount in cash equal to the same fraction of the
current market value of a whole Right.  For the purposes of this Section 14(a),
the current market value of a whole Right shall be the closing price of a Right
for the Trading Day immediately prior to the date on which such fractional
Rights otherwise would have been issuable.  The closing price for any Trading
Day shall be the last sale price on such day, regular way, or, in case no such
sale takes place on such day, the average of the closing bid and asked prices,
regular way, on such day, in either case as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the NASDAQ or, if the Rights are not listed or admitted
to trading on the Nasdaq, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal United
States 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 United
States national securities exchange, the last quoted sale price on such day or,
if not so quoted, the average of the high bid and low asked prices on such day
in the over-the-counter market as reported in any publication or by any service
which so reports over-the-counter market prices or, if on such day the Rights
are not quoted by any such system, the average of the closing bid and asked
prices on such day as furnished by a professional market maker making a market
in the Rights selected by a majority of the Board of Directors of the Company.
If on such day no such market maker is making a market in the Rights, the
current market value of the Rights on such day shall be determined in good faith
by a majority of the Board of Directors of the Company, whose determination
shall be described in a statement filed with the Rights Agent and shall be
binding and conclusive for all purposes.

          (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are integral multiples of one one-
thousandth 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 integral multiples of one one-thousandth of a
share of Preferred Stock).  Fractions of shares of Preferred Stock may, at the
election of the Company, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Company and a depositary selected by it,
provided that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the Preferred Stock.  In lieu of fractional
shares of Preferred Stock that are not integral multiples of one one-thousandth
of a share of Preferred Stock, the Company may at its option (i) issue scrip or
warrants in registered form (either represented by a certificate or
uncertificated) or in bearer form (represented by a certificate) which shall
entitle the holder to receive a full one one-thousandth of a share of Preferred
Stock upon the surrender of such scrip or warrants aggregating a full one one-
thousandth of a share of Preferred Stock, or (ii) pay to the registered holders
of Rights Certificates at the time such Rights Certificates are exercised as
provided in this Agreement an amount in cash equal to the same fraction of the
current market value of a share of Preferred Stock.  For purposes of this
Section 14(b), the current market value of a share of Preferred Stock shall be
the closing price of a share of Preferred Stock (as determined pursuant to the
second sentence of the definition of "Current Market Price" in Section 1) for
the Trading Day immediately prior to the date of such exercise.

                                     - 26 -

          (c)  The Company shall not be required to issue fractions of shares of
Common Stock or Common Stock Equivalents or to distribute certificates which
evidence fractional shares of Common Stock or Common Stock Equivalents. In lieu
of such fractional shares of Common Stock or Common Stock Equivalents, the
Company shall pay to the registered holders of the Rights Certificates with
regard to which such fractional shares of Common Stock or Common Stock
Equivalents would otherwise be issuable an amount in cash equal to the product
derived by multiplying (x) the subject fraction, by (y) Current Market Price of
the Company's Common Stock.

          (d) The holder of a Right by his acceptance thereof expressly waives
any right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as otherwise provided in this Agreement).

          Section 15.    Rights of Action.  Except as otherwise provided, all
                         ----------------                                    
rights of action in respect of this Agreement are vested in the respective
registered holders of the Rights Certificates (and, prior to the Distribution
Date, any registered holders of associated Common Stock); and any registered
holder of any Rights Certificate (or, prior to the Distribution Date, any share
of associated Common Stock), without the consent of the Rights Agent or of the
holder of any other Right, may, on 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 rights pursuant to
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 Rights Holders Concerning Transfer and
                         ---------------------------------------------------
Ownership of Rights.  Every holder of a Right by accepting the same consents and
- - -------------------                                                             
agrees with the Company and the Rights Agent and with every other holder of a
Right that:

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

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

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

          Section 17.  Rights Holder Not Deemed a Stockholder.  No holder, as
                       --------------------------------------                
such, of any Rights Certificate shall be entitled to vote or to receive
dividends or distributions or shall be deemed for any purpose the holder of
Preferred Stock or any other securities, cash or other property which may at any
time be issuable on the exercise of the Rights represented thereby, nor shall
anything contained in this Agreement or in any Rights Certificate be construed
to confer upon the holder of any Rights Certificate, as such, any of the rights
of a stockholder of the Company, including, without limitation, any right (i) to
vote for the election of directors or upon any matter submitted to stockholders
at any meeting thereof, (ii) to give or withhold consent to any corporate
action, (iii) to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 24), (iv) to receive dividends,
distributions or subscription rights, (v) to institute, as a holder of Preferred
Stock or other securities issuable on exercise of the Rights represented by any
Rights Certificate, any derivative action on behalf of the Company, or
otherwise, until and only to the extent that the Right or Rights evidenced by
such Rights Certificate shall have been exercised in accordance with the
provisions of this Agreement.

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

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

          Section 19.    Merger or Consolidation or Change of Name of Rights
                         ---------------------------------------------------
Agent.  Any corporation into which the Rights Agent or any successor Rights
- - -----                                                                      
Agent may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any corporation succeeding to the
corporate trust business of the Rights Agent or any successor Rights Agent,
shall be the successor to the Rights Agent under this Agreement without the
execution or filing of any document or any further act on the part of any of the
parties hereto, provided 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 Rights Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the
predecessor Rights Agent and deliver

                                     - 28 -
<PAGE>
 
such Rights Certificate so countersigned; and in case at that time any of the
Rights Certificates shall not have been countersigned, any successor Rights
Agent may countersign such Rights Certificate either in the name of the
predecessor Rights Agent or in the name of the successor Rights Agent; and in
all such cases such Rights Certificates shall have the full force provided in
the Rights Certificates and in this Agreement.

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

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

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

          (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter
(including, without limitation, the identity of any Acquiring Person or any
Affiliate or Associate of an Acquiring Person or the determination of Current
Market Price) be proved or established by the Company prior to taking or
suffering any action hereunder, such fact or matter (unless other evidence in
respect thereof be specifically prescribed in this Agreement) may be deemed to
be conclusively proved and established by a certificate signed by the Chairman
of the Board, the Chief Executive Officer, the President, the Chief Financial
Officer, any Vice President or the Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization to the Rights
Agent for any action taken or suffered in good faith by it under the provisions
of this Agreement in reliance upon such certificate.

          (c) The Rights Agent shall be liable hereunder only for the gross
negligence, bad faith, willful misconduct or breach of this Agreement by it or
its attorneys or agent.

          (d) The Rights Agent shall not be liable for or by reason of any of
the statements of fact or recitals contained in this Agreement or in the Rights
Certificates (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 of this
Agreement (except the due execution

                                     - 29 -
<PAGE>
 
and delivery of this Agreement by the Rights Agent) or in respect of the
validity or execution of any Rights Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change or adjustment in the terms of the
Rights (including the manner, method or amount thereof) provided for in Sections
3, 11, 13 or 23 or the ascertaining of the existence of facts that would require
any such change or adjustment (except with respect to the exercise of Rights
evidenced by Rights Certificates after actual notice of any change or adjustment
is required); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any shares
of Preferred Stock, Common Stock or other securities to be issued pursuant to
this Agreement or any Rights Certificate or as to whether any shares of
Preferred Stock, Common Stock or other securities will, when issued, be validly
authorized and issued, fully paid and nonassessable.

          (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performance 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 Chief Executive Officer, the President, the Chief
Financial Officer, any Vice President or the Secretary of the Company, and to
apply to such officers for advice or instructions in connection with its duties,
and it shall not be liable for any action taken or suffered to be taken by it in
good faith in accordance with instructions of any such officer.

          (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 the Rights Agent were not
serving as such under this Agreement.  Nothing in this Agreement shall preclude
the Rights Agent from acting in any other capacity  for the Company or for any
other legal entity.

          (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents.

          (j) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed or indicates an affirmative response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise 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

                                     - 30 -
<PAGE>
 
writing mailed to the Company and to each transfer agent of the Common Stock or
Preferred Stock by registered or certified mail, and to the holders of the
Rights Certificates by first-class mail.  The Company may remove the Rights
Agent or any successor Rights Agent upon 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 or Preferred Stock by registered or certified
mail, and to the holders of the Rights Certificates by first-class mail.  If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent.
Notwithstanding any other provision of this Agreement, in no event shall the
resignation or removal of a Rights Agent be effective until a successor Rights
Agent shall have been appointed and have accepted such appointment.  If the
Company shall fail to make such appointment within a period of 30 days after
such removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by any holder of a
Rights Certificate (who shall, with such notice, submit his Rights Certificate
for inspection by the Company), then the incumbent Rights Agent or the
registered holder of any Rights Certificate may apply to any court of competent
jurisdiction for the appointment of a new Rights Agent.  Any successor Rights
Agent, whether appointed by the Company or by such a court, shall be a
corporation organized and doing business under the laws of the United States or
of the State of New York (or of any other state of the United States so long as
such corporation is authorized to conduct a corporate trust or banking business
in the State of New York) in good standing, which is authorized under such laws
to exercise 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.  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 such 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 or
Preferred Stock, and mail a notice thereof in writing to the registered holders
of the Rights Certificates.  Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be.

          Section 22.    Issuance of New Rights Certificates.  Notwithstanding
                         -----------------------------------                  
any of the provisions of this Agreement or of the Rights Certificates to the
contrary, the Company may, at its option, issue new Rights Certificates
evidencing new Rights in such form as may be approved by a majority of the Board
of Directors of the Company to reflect any adjustment or change in the Purchase
Price per share and the number or kind or class of securities, cash or other
property purchasable under the Rights Certificates made in accordance with the
provisions of this Agreement.

           Section 23.  Redemption and Termination.
                        -------------------------- 

          (a) The Board of Directors of the Company may, at its option, at any
time prior to the earlier of (i) the Stock Acquisition Date and (ii) the
Expiration Date, redeem all but not less than all of the then-outstanding Rights
at a redemption price of $0.01 per Right (the "Redemption Price") appropriately
                                               ----------------                
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date of this Agreement. The Company may, at its option, pay
the Redemption Price in cash, shares (including fractional shares) of Common
Stock (based on the Current Market Price of the Common Stock at the time of
redemption) or any other form of consideration deemed appropriate by the Board
of Directors.

          (b) At the time and date of effectiveness set forth in any resolution
of the Board of Directors of the Company ordering the redemption of the Rights,
without any further action and without any further notice, the right to exercise
the Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price; provided, however, that such
                                          --------  -------           
resolution of the Board of Directors of the Company may be revoked, rescinded or
otherwise modified at any time prior to the time and date of effectiveness set
forth in such resolution, in which event the right to exercise will not
terminate at the time and date originally set for such termination by the Board
of Directors of the Company. As soon as practicable after the action of the
Board of Directors of the Company ordering the redemption of the Rights, the
Company shall give notice of such redemption to the Rights Agent and to the
holders of the then-outstanding Rights by mailing such notice to all such
holders at their last addresses as they appear upon the registry books of the
Rights Agent or, prior to the issuance of Rights Certificates, on the registry
books of the transfer agent for the Common Stock.  Any notice which is mailed in
the manner provided in this Agreement 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.  In any case,
failure to give such notice by mail, or any defect in the notice, to any
particular holder of Rights shall not affect the sufficiency of the notice to
other holders of Rights.  In the case of a redemption permitted under this
Section 23, the Company may, at its option, discharge all of its obligations
with respect to the Rights by (i) issuing a press release announcing the manner
of redemption of the Rights and (ii) mailing payment of the Redemption Price to
the registered holders of the Rights at their last addresses as they appear on
the registry books of the Rights Agent or, prior to the issuance of the Rights
Certificates, on the registry books of the transfer agent for the Common Stock,
and upon such action, all outstanding Rights Certificates shall be null and void
without any further action by the Company.  Neither the Company nor any of its
Affiliates or Associates may redeem, acquire or purchase for value any Rights at
any time in any manner other than that specifically set forth in this Section

purchase any additional shares of Preferred Stock or shares of stock of any
class or any other securities, rights or options, or (c) effect any

only the subdivision of outstanding shares of Preferred Stock, a change in the
par value of such Preferred Stock or a change from par value to no par value),
or (d) directly or indirectly effect any consolidation or merger into or with,
or effect any sale, lease, exchange, or other transfer or disposition (or to

determining holders of the Preferred Stock for purposes of such action, 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, if any, by

affect the legality or validity of the action taken by the Company or the vote
upon any such action.

                     CABLE DESIGN TECHNOLOGIES CORPORATION

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


          I, Kenneth Hale, Chief Financial Officer of Cable Design Technologies
Corporation, a corporation organized and existing under the General Corporation
Law of the State of Delaware, in accordance with the provisions of Section 151
thereof, DO HEREBY CERTIFY:
         
          That pursuant to the authority conferred upon the Board of Directors
by the Restated Certificate of Incorporation of the Corporation, the Board of
Directors on December 10, 1996, adopted the following resolution creating a
series of 100,000 shares of Preferred Stock designated as Junior Participating
Preferred Stock, Series A:

          RESOLVED, that pursuant to the authority vested in the Board by
ARTICLE FOUR of the Restated Certificate of Incorporation and out of the
Preferred Stock authorized therein, the Board hereby authorizes that a series of
Preferred Stock of the Corporation be, and it hereby is, created, and that the
designation and amount thereof and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such series,
and the qualifications, limitations or restrictions thereof are as follows:

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

          Section 2.  Dividends and Distributions.
                      --------------------------- 

     (A)  Subject to the prior and superior rights of the holders of any shares
of any series of Preferred Stock ranking prior and superior to the shares of
Series A Preferred Stock with respect to dividends, the holders of shares of
Series A Preferred Stock, in preference to the holders of Common Stock and of
any other junior stock, shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash on the fifteenth day of March, June,
September and December in each year (each such date being referred to herein as
a "Quarterly Dividend Payment Date"), commencing on
<PAGE>
 
the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $25.00 or (b) the Adjustment
Number (as defined below) times the aggregate per share amount of all cash
dividends, and the Adjustment Number times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock since the immediately preceding Quarterly Dividend Payment Date or,
with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Preferred Stock.  The
"Adjustment Number" shall initially be 1000.  In the event the Corporation shall
at any time after January 1, 1997 (i) declare or pay any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock into a greater number of shares or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the Adjustment
Number in effect immediately prior to such event shall be adjusted by
multiplying such Adjustment 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)  The Corporation shall declare a dividend or distribution on the Series
A Preferred Stock as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided that, in the event no
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $25.00 per share on the Series A
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

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

                                      -2-
<PAGE>
 
of Directors may fix a record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

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

     (A) Each share of Series A Preferred Stock shall entitle the holder thereof
to a number of votes equal to the Adjustment Number (as adjusted from time to
time pursuant to Section 2(A) hereof) on all matters submitted to a vote of the
stockholders of the Corporation.

     (B)  Except as otherwise provided herein, in the Restated Certificate of
Incorporation or by-laws, the holders of shares of Series A Preferred Stock and
the holders of shares of Common Stock shall vote together as one class on all
matters submitted to a vote of stockholders of  the Corporation.

     (C)  (i)  If at any time dividends on any Series A 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") that shall extend until such time when all accrued and unpaid
dividends for all previous quarterly dividend periods and for the current
quarterly period on all shares of Series A Preferred Stock then outstanding
shall have been declared and paid or set apart for payment. During each default
period, (1) the number of Directors shall be increased by two, effective as of
the time of election of such Directors as herein provided, and (2) the holders
of Series A Preferred Stock and the holders of other Preferred Stock upon which
these or like voting rights have been conferred and are exercisable (the "Voting
Preferred Stock") with dividends in arrears equal to six quarterly dividends
thereon, voting as a class, irrespective of series, shall have the right to
elect such two Directors.

          (ii)  During any default period, such voting right of the holders of
Series A Preferred Stock may be exercised initially at a special meeting called
pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of
stockholders, and thereafter at annual meetings of stockholders, provided that
such voting right shall not be exercised unless the holders of at least one-
third in number of the shares of Voting Preferred Stock outstanding shall be
present in person or by proxy.  The absence of a quorum of the holders of Common
Stock shall not affect the exercise by the holders of Voting Preferred Stock of
such voting right.

          (iii)  Unless the holders of Voting 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
Voting Preferred Stock outstanding,

                                      -3-
<PAGE>
 
irrespective of series, may request, the calling of a special meeting of the
holders of Voting Preferred Stock, which meeting shall thereupon be called by
the Chairman of the Board, the President, an Executive Vice President, a Vice
President or the Secretary of the Corporation.  Notice of such meeting and of
any annual meeting at which holders of Voting Preferred Stock are entitled to
vote pursuant to this paragraph (C)(iii) shall be given to each holder of record
of Voting 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 10 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 Voting Preferred Stock outstanding.
Notwithstanding the provisions of this paragraph (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 the stockholders.

          (iv)  In any default period, after the holders of Voting Preferred
Stock shall have exercised their right to elect Directors voting as a class, (x)
the Directors so elected by the holders of Voting 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 be filled by vote of a majority of the remaining Directors
theretofore elected by the holders of the class or classes of stock which
elected the Director whose office shall have become vacant.  References in this
paragraph (C) to Directors elected by the holders of a particular class or
classes 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 Voting Preferred Stock as a class to elect Directors shall
cease, (y) the term of any Directors elected by the holders of Voting Preferred
Stock as a class shall terminate and (z) the number of Directors shall be such
number as may be provided for in the Restated Certificate of Incorporation or
By-Laws irrespective of any increase made pursuant to the provisions of
paragraph (C) of this Section 3 (such number being subject, however, to change
thereafter in any manner provided by law or in the Restated Certificate of
Incorporation or By-Laws). 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)  Except as set forth herein, holders of Series A Preferred Stock shall
have no special voting rights and their consent shall not be required (except to
the extent they are entitled to vote with holders of Common Stock as set forth
herein) for taking any corporate action.

          Section 4.  Certain Restrictions.
                      -------------------- 

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

          (ii) declare or pay dividends on or make any other distributions on

such junior stock in exchange for shares of any stock of the Corporation ranking
junior (either as to dividends or upon dissolution, liquidation or winding up)
to the Series A Preferred Stock; or

          (iv)  purchase or otherwise acquire for consideration any shares of

Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all other such parity stock in proportion to the total
amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up.

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

          This certifies that _________________________, or registered assigns,
is the registered owner of the number of Rights set forth above, each of which
entitles the owner thereof, subject to the terms, provisions and conditions of
the Rights Agreement dated as of December 11, 1996 (the "Rights Agreement")
between Cable Design Technologies Corporation, a Delaware corporation (the
"Company"), and The First National Bank of Boston, a national banking
association (the "Rights Agent"), unless notice of redemption shall have been
previously given by the Company, to purchase from the Company at any time after
the Distribution Date (as such term is defined in the Rights Agreement) and
prior to 5:00 P.M. (New York, New York time) on December 11, 2006, at the
principal corporate trust office of the Rights Agent, or at the office of its
successor as Rights Agent, one one-thousandth of a fully paid nonassessable
share of the Junior Participating Preferred Stock, Series A, par value $1.00 per
share, of the Company (the "Preferred Stock"), at a purchase price (the
"Purchase Price") of $150.00 per one one-thousandth share, upon presentation and
surrender of this Rights Certificate with the Form of Election to Purchase duly
executed.  The Purchase Price may be paid in cash or by certified bank check or
bank draft payable to the order of the Company.

          As provided in the Rights Agreement, the Purchase Price and the number
of shares of Preferred Stock or other securities, cash or other property which
may be purchased upon the exercise of the Rights evidenced by this Rights
Certificate are subject to modification and adjustment upon the happening of
certain events.
<PAGE>
 
          If the Rights evidenced by this Rights Certificate are or were
formerly beneficially owned, on or after the earlier of the Distribution Date
and the Stock Acquisition Date, by (i) an Acquiring Person or any Associate or
Affiliate of an Acquiring Person, or (ii) a direct or indirect transferee of an
Acquiring Person (or of any Associate or Affiliate of an Acquiring Person), such
Rights may become null and void, in which event the holder of any such Right
(including any subsequent holder) shall not have any right with respect to such
Right.

          This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates.
Capitalized terms used but not defined in this Rights Certificate that are
defined in the Rights Agreement shall have the same meanings ascribed to them in
the Rights Agreement.  Copies of the Rights Agreement are on file at the
principal executive offices of the Company and the above-mentioned office of the
Rights Agent.

          This Rights Certificate, with or without other Rights Certificates,
upon surrender at the principal corporate trust office of the Rights Agent, may
be exchanged for another Rights Certificate or Rights Certificates of like tenor
and date evidencing Rights entitling the holder to purchase a like aggregate
number of shares of Preferred Stock or other property as the Rights evidenced by
the Rights Certificate or Rights Certificates surrendered entitled such holder
to purchase.  If this Rights Certificate shall be exercised in part, the holder
shall be entitled to receive upon surrender hereof another Rights Certificate or
Rights Certificates for the number of whole Rights not exercised.

          Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate (a) may be redeemed by the Board of Directors of
the Company at its option at a redemption price of $.01 per Right subject to
adjustment, payable, at the election of the Company, in cash or shares
(including fractional shares) of Common  Stock or such other consideration as
the Board of Directors may determine, at any time prior to the earlier of (i)
12:00 a.m. (midnight, New York, New York time) on the Stock Acquisition Date,
and (ii) the Expiration Date, or, (b) may be exchanged after the Stock
Acquisition Date by the Board of Directors of the Company at its option in whole
or in part for shares of the Company's Common Stock or other Company securities.

          No fractional shares of Preferred Stock (other than fractions that are
integral multiples of one one-thousandth of a share of Preferred Stock, which
may, at the election of the Company, be evidenced by depository receipts) are
required to be issued upon the exercise of any Right or Rights evidenced hereby,
but in lieu thereof the Company may elect to (i) evidence fractional shares by
depositary receipts, (ii) issue scrip or warrants in registered form (either
represented by a certificate or uncertificated) or in bearer form (represented
by a certificate) which shall entitle the holder to receive a full share upon
the surrender of such

                                       2

scrip or warrants aggregating a full share, or (iii) make a cash payment, as
provided in the Rights Agreement.

          No holder of this Rights Certificate, as such, shall be entitled to
vote or to receive dividends on, or shall be deemed for any purpose the holder
of, Preferred Stock or of any other securities, cash or property which may at
any time be issuable on the exercise hereof, nor shall anything contained in the
Rights Agreement or this Certificate be construed to confer upon the holder
hereof, as such, any of the rights of a stockholder of the Company, including,
without limitation, 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 to institute, as a holder of
Preferred Stock or other securities issuable on the exercise of the Rights
represented by this Certificate, any derivative action, or otherwise, until and
only to the extent the Right or Rights evidenced by this Rights Certificate
shall have been exercised as provided in the Rights Agreement.

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

                                                                       ---------

                 SUMMARY OF RIGHTS TO PURCHASE PREFERRED SHARES


          On December 11, 1996, the Board of Directors of Cable Design
Technologies Corporation (the "Company") authorized the issuance of one
preferred share purchase right (a "Right") for each outstanding share of common
stock, par value $0.01 per share (the "Common Shares"), of the Company.  The
distribution is payable to the stockholders of record at the close of business
on December 26, 1996 (the "Record Date"), and with respect to all Common Shares
that become outstanding after the Record Date and prior to the earliest of the
Distribution Date (as defined below), the redemption of the Rights, the exchange
of the Rights, and the expiration of the Rights (and, in certain cases,
following the Distribution Date).  Each Right entitles the registered holder to
purchase from the Company one one-thousandth of a share of a Junior
Participating Preferred Stock, Series A, par value $1.00 per share, of the
Company (the "Preferred Shares") at a price of $150.00 per one one-thousandth of
a Preferred Share (the "Purchase Price"), subject to adjustment.  The
description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") between the Company and The First National Bank of Boston,
as Rights Agent (the "Rights Agent").

          Until the earlier to occur of (i) the expiration of the Company's
redemption rights following the date of public disclosure that a person or group
other than certain exempt persons (an "Acquiring Person"), together with persons
affiliated or associated with such Acquiring Person (other than those that are
exempt persons), has acquired, or obtained the right to acquire, beneficial
ownership of 20% or more of the outstanding Common Shares (the "Stock
Acquisition Date") or (ii) the tenth business day after the date of commencement
or public disclosure of an intention to commence a tender offer or exchange
offer by a person other than an exempt person if, upon consummation of the
offer, such person could acquire beneficial ownership of  20% or more of the
outstanding Common Shares (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced by Common Share certificates
and not by separate certificates.  The Rights Agreement provides that, until the
Distribution Date (or earlier redemption, exchange or expiration of the Rights),
the Rights will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption, exchange or expiration of the Rights),
new Common Share certificates issued after the Record Date, upon transfer or new
issuance of the Common Shares, will contain a notation incorporating the Rights
Agreement by reference.  Until the Distribution Date (or earlier redemption,
exchange or expiration of the Rights) the surrender for transfer of any
certificate for Common Shares, with or without such notation or a copy of this
Summary of Rights being attached thereto, will also constitute the transfer of
the Rights associated with the Common Shares represented by such certificate.
As soon as practicable following the Distribution Date, separate certificates
evidencing the Rights ("Right Certificates") will be mailed to holders of record
of the Common Shares as of the close of business on the Distribution Date, and
such separate Right Certificates alone will evidence the Rights.
<PAGE>
 
          The Rights will first become exercisable after the Distribution Date
(unless sooner redeemed or exchanged).  The Rights will expire at the close of
business on December 11, 2006 (the "Expiration Date"), unless earlier redeemed
or exchanged by the Company as described below.

          The Purchase Price payable, and the number of Preferred Shares or
other securities, cash or other property issuable, upon exercise of the Rights
are subject to adjustment from time to time to prevent dilution (i) in the event
of a stock dividend or distribution on, or a subdivision, combination or
reclassification of, the Preferred Shares, (ii) upon the grant to holders of the
Preferred Shares of certain rights, options or warrants to subscribe for
Preferred Shares or securities convertible into Preferred Shares at less than
the current market price of the Preferred Shares or (iii) upon the distribution
to holders of the Preferred Shares of evidences of indebtedness or assets
(excluding regular periodic cash dividends out of earnings or retained earnings)
or of subscription rights or warrants (other than those referred to above).  In
addition, the Purchase Price payable and the number of Preferred Shares
purchasable, on exercise of a Right is subject to adjustment in the event that
the Company should (i) declare or pay any dividend on the Common Shares payable
in Common Shares or (ii) effect a subdivision or combination of the Common
Shares into a different number of Common Shares.

          In the event that a person becomes an Acquiring Person, proper
provision shall be made so that each holder of a Right, other than Rights that
are or were beneficially owned by the Acquiring Person and certain related
persons and transferees (which will thereafter be void), shall thereafter have
the right to receive upon exercise of such Right that number of Common Shares
(or other securities) having at the time of such transaction a market value of
two times the exercise price of the Right. In the event that a person becomes an
Acquiring Person and the Company is involved in a merger or other business
combination transaction where the Company is not the surviving corporation or
where Common Stock is changed or exchanged or in a transaction or transactions
in which 50% or more of its consolidated assets or earning power are sold,
proper provision shall be made so that each holder of a Right (other than such
Acquiring Person and certain related persons or transferees) shall thereafter
have the right to receive, upon the exercise thereof at the then current
exercise price of the Right, that number of shares of common stock of the
acquiring company which at the time of such transaction would have a market
value of two times the exercise price of the Right. In addition, the Company's
Board of Directors has the option of exchanging all or part of the Rights
(excluding void Rights) for an equal number of Common Shares in the manner
described in the Rights Agreement.

          With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-thousandth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading date prior to the date
of exercise.

          At any time prior to public disclosure that an Acquiring Person has
become such, the Board of Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (the "Redemption Price"),
payable in cash, shares (including fractional shares) of

Common Stock or any other form of consideration deemed appropriate by the Board
of Directors. Immediately upon action of the Board of Directors ordering
redemption of the Rights, the ability of holders to exercise the Rights will
terminate and the only rights of such holders will be to receive the Redemption
Price.

          At any time prior to public disclosure that an Acquiring Person has
become such, the Board of Directors of the Company may amend or supplement the
Rights Agreement without the approval of the Rights Agent or any holder of the
Rights, except for an amendment or supplement which would change the Redemption
Price, provide for an earlier expiration date of the Rights or change the
Purchase Price.  Thereafter, the Board of Directors of the Company may amend or
supplement the Rights Agreement without such approval only to cure ambiguity,
correct or supplement any defective or inconsistent provision or change or
supplement the Rights Agreement in any manner which shall not adversely affect
the interests of the holders of the Rights (other than an Acquiring Person or an
affiliate or associate thereof).  Immediately upon the action of the Board of
Directors providing for any amendment or supplement, such amendment or
supplement will be deemed effective.

          The Preferred Shares purchasable upon exercise of the Rights will not
be redeemable. Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment equal to the greater of $25.00 per share and 1,000
times the dividend declared per Common Share.  In the event of liquidation, the
holders of the Preferred Shares will be entitled to a minimum preferential
liquidation payment equal to the greater of $100 per share and 1,000 times the
payment made per Common Share.  Each Preferred Share will have 1,000 votes per
share, voting together with the Common Shares.  In the event of any merger,
consolidation or other transaction in which Common Shares are exchanged, each
Preferred Share will be entitled to receive 1,000 times the amount received per
Common Share.

          The Rights have certain anti-takeover effects.  The Rights may cause
substantial dilution to a person or group other than an exempt person that
attempts to acquire the Company on terms not approved by the Board, except
pursuant to an offer conditioned on a substantial number of Rights being
acquired.  The Rights should not interfere with any merger or other business
combination approved by the Board of Directors prior to the time a person or
group other than an exempt person has acquired beneficial ownership of 20% or
more of the Common Shares, because until such time the Rights may generally be
redeemed by the Company at $.01 per Right.

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

          A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to an Application for Registration on Form 8-A
and as an Exhibit to the Company's Current Report on Form 8-K.  A copy of the
Rights Agreement is available free of charge from the Company.  This summary
description of the Rights does not purport to be complete and is qualified in
its entirety by reference to the Rights Agreement, which is hereby incorporated
herein by reference.
