                        Preferred Share Purchase Rights
<PAGE>   2
ITEM 1. DESCRIPTION OF THE REGISTRANT'S SECURITIES TO BE REGISTERED.

         On January 16, 1997, the Board of Directors of Teltrend Inc. (the
"Company") declared a dividend of one preferred share purchase right (a
"Right") for each outstanding share of common stock, par value $.01 per share,
of the Company (the "Common Stock").  The dividend is payable on January 27,
1997 (the "Record Date") to the holders of record of the Common Stock as of the
close of business on that date.  Each Right entitles the registered holder to
purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share, of the Company (the
"Preferred Stock") at a price of $160.00 per one one-hundredth of a share of
Preferred Stock (the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement dated as of January
16, 1997, as the same may be amended from time to time (the "Rights
Agreement"), between the Company and LaSalle National Bank, as Rights Agent
(the "Rights Agent"), a copy of which is filed as an exhibit hereto.

         Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions, an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding shares of Common Stock or (ii) 10 business days
(or such later date as may be determined by action of the Board of Directors
prior to such time as any person or group of affiliated persons becomes an
Acquiring Person) following the commencement of, or announcement of an
intention to make, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of 15% or more of
the outstanding shares of Common Stock (the earlier of such dates being called
the "Distribution Date"), the Rights will be evidenced, with respect to any of
the Common Stock certificates outstanding as of the Record Date, by such Common
Stock certificate and not by a separate Rights Certificate (as defined).

         The Rights Agreement provides that, until the Distribution Date (or
earlier expiration of the Rights), the Rights will be transferred with and only
with the Common Stock.  Until the Distribution Date (or earlier expiration of
the Rights), new Common Stock certificates issued after the Record Date upon
transfer or new issuances of Common Stock will contain a notation incorporating
the Rights Agreement by reference.  Until the Distribution Date (or earlier
expiration of the Rights), the surrender for transfer of any certificates for
shares of Common Stock outstanding as of the Record Date, even without such
notation, will also constitute the transfer of the Rights associated with the
shares of Common Stock 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 Stock
as of the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.

         The Rights are not exercisable until the Distribution Date.  The
Rights will expire on January 16, 2007 (the "Final Expiration Date"), unless
the Final Expiration Date is advanced or extended or unless the Rights are
earlier redeemed or exchanged by the Company, in each case as described below.

         The Purchase Price payable, and the number of shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights is
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-current market price of the Preferred Stock or (iii) upon
the distribution to holders of the Preferred Stock of evidences of indebtedness
or assets (excluding regular periodic cash dividends or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

         The number of outstanding Rights is subject to adjustment in the event
of a stock dividend on the Common Stock payable in shares of Common Stock or
subdivisions, consolidations or combinations of the Common Stock occurring, in
any such case, prior to the Distribution Date.





                                     -2-
<PAGE>   3
         Shares of Preferred Stock purchasable upon exercise of the Rights will
not be redeemable.  Each share of Preferred Stock will be entitled, when, as
and if declared, to a minimum preferential quarterly dividend payment of $.05
per share but will be entitled to an aggregate dividend of 100 times the
dividend declared per share of Common Stock.  In the event of liquidation,
dissolution or winding up of the Company, the holders of the Preferred Stock
will be entitled to a minimum preferential payment of $160.00 per share (plus
any accrued but unpaid dividends) but will be entitled to an aggregate payment
of 100 times the payment made per share of Common Stock.  Each share of
Preferred Stock will have 100 votes, voting together with the Common Stock.
Finally, in the event of any merger, consolidation or other transaction in
which outstanding shares of Common Stock are converted or exchanged, each share
of Preferred Stock will be entitled to receive 100 times the amount received
per share of Common Stock.  These rights are protected by customary
antidilution provisions.

         In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person or its affiliates, associates or
certain transferees (which will thereupon become void), will thereafter have
the right to receive upon exercise of a Right that number of shares of Common
Stock having a market value of two times the exercise price of the Right.

         In the event that, after a person or group has become an Acquiring
Person, the Company is acquired in a merger or other business combination
transaction or 50% or more of its consolidated assets or earning power are
sold, proper provisions will be made so that each holder of a Right (other than
Rights beneficially owned by an Acquiring Person or its affiliates, associates
or certain transferees, which will have become void) will thereafter have the
right to receive upon the exercise of a Right that number of shares of common
stock of the person with whom the Company has engaged in the foregoing
transaction (or its parent) that at the time of such transaction have a market
value of two times the exercise price of the Right.

         At any time after any person or group becomes an Acquiring Person and
prior to the earlier of one of the events described in the previous paragraph
or the acquisition by such Acquiring Person of 50% or more of the outstanding
shares of Common Stock, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring Person or its affiliates,
associates, or certain transferees, which will have become void), in whole or
in part, for shares of Common Stock or Preferred Stock (or a series of the
Company's preferred stock having equivalent rights, preferences and
privileges), at an exchange ratio of one share of Common Stock (subject to
customary anti- dilution provisions), or a fractional share of Preferred Stock
(or other preferred stock) equivalent in value thereto, per Right.

         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 shares of Preferred Stock or Common Stock
will be issued (other than fractions of Preferred Stock which are integral
multiples of one one-hundredth of a share of Preferred Stock, 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 current market price of
the Preferred Stock or the Common Stock.

         At any time prior to the time an Acquiring Person becomes 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"), subject to
adjustment.  The redemption of the Rights may be made effective at such time,
on such basis and with such conditions as the Board of Directors in its sole
discretion may establish.  Immediately upon any redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders
of Rights will be to receive the Redemption Price.

         For so long as the Rights are then redeemable, the Company may, except
with respect to the Redemption Price, amend the Rights Agreement in any manner.
After the Rights are no longer redeemable, the Company generally may, except
with respect to the Redemption Price, amend the Rights Agreement in any manner
that does not adversely affect the interests of holders of the Rights.





                                      -3-
<PAGE>   4
         Until a Right is exercised or exchanged, 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.

         As of January 16, 1997, there were approximately 6,429,414 shares of
Common Stock outstanding.  Each outstanding share of Common Stock as of the
close of business on January 27, 1997 will receive one Right.

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

         This summary description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement, as the
same may be amended from time to time, which is hereby incorporated herein by
reference.

                                RIGHTS AGREEMENT


         Rights Agreement, dated as of January 16, 1997 ("Agreement"), between
Teltrend Inc., a Delaware corporation (the "Company"), and LaSalle National
Bank, as Rights Agent (the "Rights Agent").

         The Board of Directors of the Company has authorized and declared a
dividend  of one preferred share purchase right (a "Right") for each share of
Common Stock (as hereinafter defined) of the Company outstanding as of the
Close of Business (as defined below) on January 27, 1997 (the "Record Date"),
each Right representing the right to purchase one one-hundredth (subject to
adjustment) of a share of Preferred Stock (as hereinafter defined), upon the
terms and subject to the conditions herein set forth, and has further
authorized and directed the issuance of one Right (subject to adjustment as
provided herein) with respect to each share of Common Stock that shall become
outstanding between the Record Date and the earlier of the Distribution Date
and the Expiration Date (as such terms are hereinafter defined); provided,
however, that Rights may be issued with respect to shares of Common Stock that
shall become outstanding after the Distribution Date and prior to the
Expiration Date in accordance with Section 22.

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

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

         (a)     "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which shall be the Beneficial Owner (as such term
is hereinafter defined) of 15% or more of the shares of Common Stock then
outstanding, but shall not include an Exempt Person (as such term is
hereinafter defined); provided, however, that (i) if the Board of Directors of
the Company determines in good faith that a Person who would otherwise be an
"Acquiring Person" became such inadvertently (including, without limitation,
because (A) such Person was unaware that it beneficially owned a percentage of
Common Stock that would otherwise cause such Person to be an "Acquiring Person"
or (B) such Person was aware of the extent of its Beneficial Ownership of
Common Stock but had no actual knowledge of the consequences of such Beneficial
Ownership under this Agreement) and without any intention of changing or
influencing control of the Company, and if such Person as promptly as
practicable divested or divests itself of Beneficial Ownership of a sufficient
number of shares of Common Stock so that such Person would no longer be an
"Acquiring Person," then such Person shall not be deemed to be or to have
become an "Acquiring Person" for any purposes of this Agreement; (ii) if, as of
the date hereof, any Person is the Beneficial Owner of 15% or more of the
shares of Common Stock outstanding, such Person shall not be or become an
"Acquiring Person" unless and until such time as such Person shall become the
Beneficial Owner of additional shares of Common Stock (other than pursuant to a

Stock in shares of Common Stock or pursuant

to a split or subdivision of the outstanding Common Stock), unless, upon
becoming the Beneficial Owner of such additional shares of Common Stock, such
Person is not then the Beneficial Owner of 15% or more of the shares of Common
Stock then outstanding; and (iii) no Person shall become an "Acquiring Person"
as the result of an acquisition of shares of Common Stock by the Company which,
by reducing the number of shares outstanding, increases the proportionate
number of shares of Common Stock beneficially owned by such Person to 15% or
more of the shares of Common Stock then outstanding, provided, however, that if
a Person shall become the Beneficial Owner of 15% or more of the shares of
Common Stock then outstanding by reason of such share acquisitions by the
Company and shall thereafter become the Beneficial Owner of any additional
shares of Common Stock (other than pursuant to a dividend or distribution paid
or made by the Company on the outstanding Common Stock in shares of Common
Stock or pursuant to a split or subdivision of the outstanding Common Stock),
then such Person shall be deemed to be an "Acquiring Person" unless upon
becoming the Beneficial Owner of such additional shares of Common Stock such
Person does not beneficially own 15% or more of the shares of Common Stock then
outstanding.  For all purposes of this Agreement, any calculation of the number
of shares of Common Stock outstanding at any particular time, including for
purposes of determining the particular percentage of such outstanding shares of
Common Stock of which any Person is the Beneficial Owner, shall be made in

rights, rights, warrants or options, or otherwise; provided, however, that a

tendered securities are accepted for purchase, (y) securities which such Person

right to vote pursuant to any agreement, arrangement or understanding;
provided, however, that a Person shall not be deemed the Beneficial Owner of,
or to beneficially own, any security by reason of such agreement, arrangement
or understanding if the agreement, arrangement or understanding to vote such
security (1) arises solely from a revocable proxy or consent given to such
Person in response to a public proxy or consent solicitation made pursuant to,
and in accordance with, the applicable rules and regulations promulgated under
the Exchange Act and (2) is not also then reportable on Schedule 13D under the
Exchange Act (or any comparable or successor report); or

                 (iii)    which are beneficially owned, directly or indirectly,
by any other Person and with respect to which such Person or any of such
Person's Affiliates or Associates has any agreement, arrangement or
understanding (other than customary agreements with and between underwriters
and selling group members with respect to a bona fide public offering of
securities) for the purpose of acquiring, holding, voting (except to the extent
contemplated by the proviso to Section 1(c)(ii)(B)) or disposing of such

                                       5
<PAGE>   9
transfer of Common Stock.  As soon as practicable after the Distribution
Date, the Company will prepare and execute, the Rights Agent will countersign
and the Company will send or cause to be sent (and the Rights Agent will, if
requested, send) by first-class, insured, postage-prepaid mail, to each record
holder of Common Stock as of the close of business on the Distribution Date

Person), at the address of such holder shown on the records of the Company, a
Right Certificate, in substantially the form of Exhibit B hereto (a "Right
Certificate"), evidencing one Right (subject to adjustment as provided herein)
for each share of Common Stock so held.  As of the Distribution Date, the
Rights will be evidenced solely by such Right Certificates.

         (b)     On the Record Date, or as soon as practicable thereafter, the
Company will send a copy of a Summary of Rights to Purchase Shares of Preferred
Stock, in substantially the form of Exhibit C hereto (the "Summary of Rights"),
by first-class, postage-prepaid mail, to each record holder of Common Stock as
of the Close of Business on the Record Date (other than any Acquiring Person or
any Associate or Affiliate of any Acquiring Person), at the address of such
holder shown on the records of the Company.  With respect to certificates for
Common Stock outstanding as of the Record Date, until the Distribution Date,
the Rights will be evidenced by such certificates registered in the names of
the holders thereof together with the Summary of Rights.  Until the
Distribution Date (or, if earlier, the Expiration Date), the surrender for
transfer of any certificate for Common Stock outstanding on the Record Date,
with or without a copy of the Summary of Rights, shall also constitute the
transfer of the Rights associated with the Common Stock represented thereby.

         (c)     Certificates issued for Common Stock (including, without
limitation, upon transfer of outstanding Common Stock, disposition of Common
Stock out of treasury stock or issuance or reissuance of Common Stock out of
authorized but unissued shares) after the Record Date but prior to the earlier
of the Distribution Date and the Expiration Date shall have impressed on,
printed on, written on or otherwise affixed to them the following legend:

                 This certificate also evidences and entitles the holder 
                 hereof to certain rights as set forth in a Rights Agreement 
                 between Teltrend Inc. (the "Company") and LaSalle National 
                 Bank, as Rights Agent, dated as of January 16, 1997 as the
                 same may be amended from time to time (the "Rights 
                 Agreement"), the terms of which are hereby incorporated 
                 herein by reference and a copy of which is on file at the 
                 principal executive offices of the Company.  Under certain
                 circumstances, as set forth in the Rights Agreement, such 
                 Rights will be evidenced by separate certificates and will no 
                 longer be evidenced by this certificate.  The Company will 
                 mail to the holder of this certificate a copy of the Rights 
                 Agreement without charge after receipt of a written request
                 therefor.  Under certain circumstances, as set forth in the 
                 Rights Agreement, Rights owned by or transferred





                                       6
<PAGE>   10
              to any Person who is or becomes an Acquiring Person (as defined 
              in the Rights Agreement) and certain transferees thereof will 
              become null and void and will no longer be transferable.

With respect to such certificates containing the foregoing legend, until the
Distribution Date the Rights associated with the Common Stock represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Stock represented thereby.  In the event that the Company purchases or
otherwise acquires any Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such Common Stock shall be deemed
canceled and retired so that the Company shall not be entitled to exercise any
Rights associated with the Common Stock which are no longer outstanding.

              Notwithstanding this paragraph (c), the omission of a legend
shall not affect the enforceability of any part of this Agreement or the rights
of any holder of the Rights.

              Section 4.  Form of Right Certificates.  The Right Certificates
(and the forms of election to purchase shares and of assignment to be printed
on the reverse thereof) shall be substantially in the form set forth in Exhibit
B hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange or interdealer quotation system on which the Rights may from time to
time be listed or quoted, or to conform to usage.  Subject to the provisions of
Sections 11, 13 and 22 hereof, the Right Certificates shall entitle the holders
thereof to purchase such number of one one-hundredths of a share of Preferred
Stock as shall be set forth therein at the price per one one-hundredth of a
share of Preferred Stock set forth therein (the "Purchase Price"), but the
number of such one one-hundredths of a share of Preferred Stock and the
Purchase Price shall be subject to adjustment as provided herein.

              Section 5.  Countersignature and Registration.

              (a)     The Right Certificates shall be executed on behalf of the
Company by the President or any Vice President of the Company, either manually
or by facsimile signature, shall have affixed thereto the Company's seal or a
facsimile thereof and shall be attested by the Secretary or any Assistant
Secretary of the Company, either manually or by facsimile signature.  The Right
Certificates shall be manually countersigned by the Rights Agent and shall not
be valid for any purpose unless countersigned.  In case any officer of the
Company who shall have signed any of the Right Certificates shall cease to be
such officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the





                                       7
<PAGE>   11
Company, such Right Certificates, nevertheless, may be countersigned by the
Rights Agent and issued and delivered by the Company with the same force and
effect as though the Person who signed such Right Certificates had not ceased
to be such officer of the Company; and any Right Certificate may be signed on
behalf of the Company by any Person who, at the actual date of the execution of
such Right Certificate, shall be a proper officer of the Company to sign such
Right Certificate, although at the date of the execution of this Agreement any
such Person was not such an officer.

              (b)     Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at an office or agency designated for such purpose,
books for registration and transfer of the Right Certificates issued hereunder.
Such books shall show the names and addresses of the respective holders of the
Right Certificates, the number of Rights evidenced on its face by each of the
Right Certificates and the date of each of the Right Certificates.

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

              (a)     Subject to the provisions of Sections 7(e), 11(a)(ii), 13
and 14 hereof, at any time after the Distribution Date and prior to the
Expiration Date, any Right Certificate or Right Certificates may be
transferred, split up, combined or exchanged for another Right Certificate or
Right Certificates, entitling the registered holder to purchase a like number
of one one-hundredths of a share of Preferred Stock as the Right Certificate or
Right Certificates surrendered then entitled such holder to purchase.  Any
registered holder desiring to transfer, split up, combine or exchange any Right
Certificate or Right Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Right Certificate or Right
Certificates to be transferred, split up, combined or exchanged at the office
or agency of the Rights Agent designated for such purpose.  Thereupon the
Rights Agent shall countersign and deliver to the Person entitled thereto a
Right Certificate or Right Certificates, as the case may be, as so requested.
The Company may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer, split
up, combination or exchange of Right Certificates.

              (b)     Subject to the provisions of Section 11(a)(ii) hereof, at
any time after the Distribution Date and prior to the Expiration Date, upon
receipt by the Company and the Rights Agent of evidence reasonably satisfactory
to them of the loss, theft, destruction or mutilation of a Right Certificate,
and, in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to them, and, at the Company's request, reimbursement to the
Company and the Rights Agent of all reasonable expenses incidental thereto, and
upon surrender to the Rights Agent and cancellation of the Right Certificate if
mutilated, the Company will make and deliver a new Right Certificate of like
tenor to the Rights Agent for delivery to the registered holder in lieu of the
Right Certificate so lost, stolen, destroyed or mutilated.

except as otherwise provided herein, exercise the Rights evidenced thereby in
whole or in part upon surrender of the Right Certificate, with the form of
election to purchase on the reverse side thereof duly executed, to the Rights
Agent at the office or agency of the Rights Agent designated for such purpose,
together with payment of the aggregate Purchase Price with respect to the total
number of one one-hundredths of a share of Preferred Stock (or other
securities, cash or other assets, as the case may be) as to which the Rights

to the time (the "Expiration Date") that is the earliest of (i) the Close of
Business on January 16, 2007 (the "Final Expiration Date"), (ii) the time at

Date") or (iii) the time at which such Rights are exchanged as provided in
Section 24 hereof.

              (b)     The Purchase Price shall be initially $160.00 for each

of a Right.  The Purchase Price and the number of one one-hundredths of a share

of a Right shall be subject to adjustment from time to time as provided in
Sections 11 and 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) of this Section 7.

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

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

              (e)     Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder of Rights upon the
occurrence of any purported transfer or exercise of Rights pursuant to Section
6 hereof or this Section 7 unless such registered holder shall have (i)
completed and signed the certificate contained in the form of assignment or
form of election to purchase set forth on the reverse side of the Rights
Certificate surrendered for such transfer or exercise and (ii) provided such
additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) thereof as the Company shall reasonably request.

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
Right Certificates shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Agreement.  The Company shall
deliver to the Rights Agent for cancellation and retirement, and the Rights
Agent shall so cancel and retire, any other Right Certificate purchased or
acquired by the Company otherwise than upon the exercise thereof.  The Rights
Agent shall deliver all canceled Right Certificates to the Company, or shall,
at the written request of the Company, destroy such canceled Right
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

              Section 9.  Availability of Shares of Preferred Stock.

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

              (c)     From and after such time as the Rights become
exercisable, the Company shall use its best efforts, if then necessary to
permit the issuance of shares of Preferred Stock





                                       10

upon the exercise of Rights, to register and qualify such shares of Preferred
Stock under the Securities Act and any applicable state securities or "Blue
Sky" laws (to the extent exemptions therefrom are not available), cause such
registration statement and qualifications to become effective as soon as
possible after such filing and keep such registration and qualifications
effective until the earlier of the date as of which the Rights are no longer
exercisable for such securities and the Expiration Date.  The Company may
temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file a registration
statement under the Securities Act and permit it to become effective.  Upon any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a
public announcement at such time as the suspension is no longer in effect.
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 under the Securities Act (if required) shall have been declared
effective.

              (d)     The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all shares of Preferred Stock
delivered upon exercise of Rights shall, at the time of delivery of the
certificates therefor (subject to payment of the Purchase Price), be duly and
validly authorized and issued and fully paid and nonassessable shares.

              (e)     The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
which may be payable in respect of the issuance or delivery of the Right
Certificates or of any shares of Preferred Stock upon the exercise of Rights.
The Company shall not, however, be required to pay any transfer tax which may
be payable in respect of any transfer or delivery of Right Certificates to a
Person other than, or the issuance or delivery of certificates or depositary
receipts for the Preferred Stock in a name other than that of, the registered
holder of the Right Certificate evidencing Rights surrendered for exercise or
to issue or deliver any certificates or depositary receipts for Preferred Stock
upon the exercise of any Rights until any such tax shall have been paid (any
such tax being payable by that holder of such Right Certificate at the time of
surrender) or until it has been established to the Company's reasonable
satisfaction that no such tax is due.

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





                                       11
<PAGE>   15
the holder of a Right Certificate shall not be entitled to any rights of a
holder of Preferred Stock for which the Rights shall be exercisable, including,
without limitation, the right to vote or to receive dividends or other
distributions, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein.

              Section 11.  Adjustment of Purchase Price, Number and Kind of
Shares and Number of Rights.  The Purchase Price, the number of shares of
Preferred Stock or other securities or property purchasable upon exercise of
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

              (a)(i)  In the event the Company shall at any time after the date
of this Agreement (A) declare and pay a dividend on the Preferred Stock payable
in shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock,
(C) combine the outstanding Preferred Stock into a smaller number of shares of
Preferred Stock or (D) issue any shares of its capital stock in a
reclassification of the Preferred Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the
continuing or surviving corporation), except as otherwise provided in this
Section 11(a), the Purchase Price in effect at the time of the record date for
such dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable
on such date, shall be proportionately adjusted so that the holder of any Right
exercised after such time shall be entitled to receive the aggregate number and
kind of shares of capital stock which, if such Right had been exercised
immediately prior to such date and at a time when the Preferred Stock transfer
books of the Company were open, the holder would have owned upon such exercise
and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right.

              (ii)    Subject to Section 24 of this Agreement, in the event any
Person becomes an Acquiring Person (the first occurrence of such event being
referred to hereinafter as the "Flip-In Event"), then (A) the Purchase Price
shall be adjusted to be the Purchase Price in effect immediately prior to the
Flip-In Event multiplied by the number of one one-hundredths of a share of
Preferred Stock for which a Right was exercisable immediately prior to such
Flip-In Event, whether or not such Right was then exercisable, and (B) each
holder of a Right, except as otherwise provided in this Section 11(a)(ii) and
Section 11(a)(iii) hereof, shall thereafter have the right to receive, upon
exercise thereof at a price equal to the Purchase Price (as so adjusted), in
accordance with the terms of this Agreement and in lieu of shares of Preferred
Stock, such number of shares of Common Stock as shall equal the result obtained
by dividing the Purchase Price (as so adjusted) by 50% of the current per share
market price of the Common Stock (determined pursuant to Section 11(d) hereof)
on the date of such Flip-In Event; provided, however, that the Purchase Price
(as so adjusted) and the number of shares of Common Stock so receivable upon
exercise of a Right shall, following the Flip-In Event, be subject to further
adjustment as appropriate in accordance with Section 11(f) hereof.





                                       12
<PAGE>   16
Notwithstanding anything in this Agreement to the contrary, however, from and
after the Flip-In Event, any Rights that are beneficially owned by (x) any
Acquiring Person (or any Affiliate or Associate of any Acquiring Person), (y) a
transferee of any Acquiring Person (or any such Affiliate or Associate) who
becomes a transferee after the Flip-In Event or (z) a transferee of any
Acquiring Person (or any such Affiliate or Associate) who became a transferee
prior to or concurrently with the Flip-In Event pursuant to either (I) a
transfer from the Acquiring Person to holders of its equity securities or to
any Person with whom it has any continuing agreement, arrangement or
understanding regarding the transferred Rights or (II) a transfer which the
Board of Directors has determined is part of a plan, arrangement or
understanding which has the purpose or effect of avoiding the provisions of
this paragraph, and subsequent transferees of such Persons, shall be void
without any further action and any holder of such Rights shall thereafter have
no rights whatsoever with respect to such Rights under any provision of this
Agreement.  The Company shall use all reasonable efforts to ensure that the
provisions of this Section 11(a)(ii) are complied with, but shall have no
liability to any holder of Right Certificates or other Person as a result of
its failure to make any determinations with respect to an Acquiring Person or
its Affiliates, Associates or transferees hereunder.  From and after the
Flip-In Event, no Right Certificate shall be issued pursuant to Section 3 or
Section 6 hereof that represents Rights that are or have become void pursuant
to the provisions of this paragraph, and any Right Certificate delivered to the
Rights Agent that represents Rights that are or have become void pursuant to
the provisions of this paragraph shall be canceled.  From and after the
occurrence of an event specified in Section 13(a) hereof, any Rights that
theretofore have not been exercised pursuant to this Section 11(a)(ii) shall
thereafter be exercisable only in accordance with Section 13 and not pursuant
to this Section 11(a)(ii).

              (iii)   The Company may at its option substitute for a share of
Common Stock issuable upon the exercise of Rights in accordance with the
foregoing subparagraph (ii) a number of shares of Preferred Stock or fraction
thereof such that the current per share market price of one share of Preferred
Stock multiplied by such number or fraction is equal to the current per share
market price of one share of Common Stock.  In the event that there shall not
be sufficient shares of Common Stock issued but not outstanding or authorized
but unissued to permit the exercise in full of the Rights in accordance with
the foregoing subparagraph (ii), the Board of Directors shall, to the extent
permitted by applicable law and any material agreements then in effect to which
the Company is a party (A) determine the excess (such excess, the "Spread") of
(1) the value of the shares of Common Stock issuable upon the exercise of a
Right in accordance with the foregoing subparagraph (ii) (the "Current Value")
over (2) the Purchase Price (as adjusted in accordance with the foregoing
subparagraph (ii)), and (B) with respect to each Right (other than Rights which
have become void pursuant to the foregoing subparagraph (ii)), make adequate
provision to substitute for the shares of Common Stock issuable in accordance
with the foregoing subparagraph (ii) upon exercise of the Right and payment of
the Purchase Price (as adjusted in accordance therewith), (1) cash, (2) a
reduction in such Purchase Price, (3) shares of Preferred Stock or other equity
securities of the Company (including, without limitation, shares or fractions
of shares of preferred stock which,





                                       13
<PAGE>   17
by virtue of having dividend, voting and liquidation rights substantially
comparable to those of the shares of Common Stock, are deemed in good faith by
the Board of Directors to have substantially the same value as the shares of
Common Stock (such shares of Preferred Stock and shares or fractions of shares
of preferred stock are hereinafter referred to as "Common Stock Equivalents")),
(4) debt securities of the Company, (5) other assets, or (6) any combination of
the foregoing, having a value which, when added to the value of the shares of
Common Stock issued upon exercise of such Right, shall have an aggregate value
equal to the Current Value (less the amount of any reduction in such Purchase
Price), where such aggregate value has been determined by the Board of
Directors upon the advice of a nationally recognized investment banking firm
selected in good faith by the Board of Directors; provided, however, that if
the Company shall not make adequate provision to deliver value pursuant to
clause (B) above within thirty (30) days following the Flip-In Event (the
"Section 11(a) (ii) Trigger Date"), then the Company shall be obligated to
deliver, to the extent permitted by applicable law and any material agreements
then in effect to which the Company is a party, upon the surrender for exercise
of a Right and without requiring payment of such Purchase Price, shares of
Common Stock (to the extent available), and then, if necessary, such number or
fractions of shares of Preferred Stock (to the extent available) and then, if
necessary, cash, which shares and/or cash have an aggregate value equal to the
Spread.  If, upon the occurrence of the Flip-In Event, the Board of Directors
shall determine in good faith that it is likely that sufficient additional
shares of Common Stock could be authorized for issuance upon exercise in full
of the Rights, then, if the Board of Directors so elects, the thirty (30) day
period set forth above may be extended to the extent necessary, but not more
than ninety (90) days after the Section 11(a) (ii) Trigger Date, in order that
the Company may seek stockholder approval for the authorization of such
additional shares (such thirty (30) day period, as it may be extended, is
herein called the "Substitution Period").  To the extent that the Company
determines that some action need be taken pursuant to the second and/or third
sentence of this Section 11(a)(iii), the Company (x) shall provide, subject to
Section 11(a)(ii) hereof and the last sentence of this Section 11(a)(iii)
hereof, that such action shall apply uniformly to all outstanding Rights and
(y) may suspend the exercisability of the Rights until the expiration of the
Substitution Period in order to seek any authorization of additional shares
and/or to decide the appropriate form of distribution to be made pursuant to
such second sentence and to determine the value thereof.  In the event of any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a
public announcement at such time as the suspension is no longer in effect.  For
purposes of this Section 11(a)(iii), the value of the shares of Common Stock
shall be the current per share market price (as determined pursuant to Section
11(d)(i)) on the Section 11(a)(ii) Trigger Date and the per share or fractional
value of any "Common Stock Equivalent" shall be deemed to equal the current per
share market price of the Common Stock.  The Board of Directors of the Company
may, but shall not be required to, establish procedures to allocate the right
to receive shares of Common Stock upon the exercise of the Rights among holders
of Rights pursuant to this Section 11(a)(iii).





                                       14
<PAGE>   18
              (b)     In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of Preferred Stock
entitling them (for a period expiring within 45 calendar days after such record
date) to subscribe for or purchase Preferred Stock (or shares having the same
rights, privileges and preferences as the Preferred Stock ("equivalent
preferred shares")) or securities convertible into Preferred Stock or
equivalent preferred shares at a price per share of Preferred Stock or
equivalent preferred shares (or having a conversion price per share, if a
security convertible into shares of Preferred Stock or equivalent preferred
shares) less than the then current per share market price of the Preferred
Stock (determined pursuant to Section 11(d) hereof) 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 preferred shares outstanding on such record date
plus the number of shares of Preferred Stock and equivalent preferred shares
which the aggregate offering price of the total number of shares of Preferred
Stock and/or equivalent preferred shares so to be offered (and/or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at such current market price, and the denominator of which shall be
the number of shares of Preferred Stock and equivalent preferred shares
outstanding on such record date plus the number of additional shares of
Preferred Stock and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right.  In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board
of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent.  Shares of Preferred Stock and
equivalent preferred shares owned by or held for the account of the Company
shall not be deemed outstanding for the purpose of any such computation.  Such
adjustment shall be made successively whenever such a record date is fixed; and
in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be
in effect if such record date had not been fixed.

              (c)     In case the Company shall fix a record date for the
making of a distribution to all holders of the Preferred Stock (including any
such distribution made in connection with a consolidation or merger in which
the Company is the continuing or surviving corporation) of evidences of
indebtedness or assets (other than a regular quarterly cash dividend or a
dividend payable in Preferred Stock) or subscription rights or warrants
(excluding those referred to in Section 11(b) hereof), the Purchase Price to be
in effect after such record date shall be determined by multiplying the
Purchase Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the then current per share market price of the
Preferred Stock (determined pursuant to Section 11(d) hereof) on such record
date, less the fair market value (as determined in good faith by the Board of
Directors of the Company whose determination shall be described in a statement
filed with the Rights Agent)





                                       15
<PAGE>   19
of the portion of the assets or evidences of indebtedness so to be distributed
or of such subscription rights or warrants applicable to one share of Preferred
Stock, and the denominator of which shall be such current per share market
price (determined pursuant to Section 11(d) hereof) of the Preferred Stock;
provided, however, that in no event shall the consideration to be paid upon the
exercise of one Right be less than the aggregate par value of the shares of
capital stock of the Company to be issued upon exercise of one Right.  Such
adjustments shall be made successively whenever such a record date is fixed;
and in the event that such distribution is not so made, the Purchase Price
shall again be adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.

              (d)(i)  Except as otherwise provided herein, for the purpose of
any computation hereunder, the "current per share market price " of any
security (a "Security " for the purpose of this Section 11(d)(i)) on any date
shall be deemed to be the average of the daily closing prices per share of such
Security for the 30 consecutive Trading Days (as such term is hereinafter
defined) immediately prior to such date; provided, however, that in the event
that the current per share market price of the Security is determined during a
period following the announcement by the issuer of such Security of (A) a
dividend or distribution on such Security payable in shares of such Security or
securities convertible into such shares, or (B) any subdivision, combination or
reclassification of such Security, and prior to the expiration of 30 Trading
Days after the ex-dividend date for such dividend or distribution, or the
record date for such subdivision, combination or reclassification, then, and in
each such case, the current per share market price shall be appropriately
adjusted to reflect the current market price per share equivalent of such
Security.  The closing price for each day shall be the last sale price, regular
way, or, in case no such sale takes place on such day, the average of the
closing bid and asked prices, regular way, in either case as reported by the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange or, if the
Security is not listed or admitted to trading on the New York Stock Exchange,
as reported in the principal consolidated transaction reporting system with
respect to securities listed on the principal national securities exchange on
which the Security is listed or admitted to trading or, if the Security is not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use, or, if on any such date the Security is not quoted by any
such organization, the average of the closing bid and asked prices as furnished
by a professional market maker making a market in the Security selected by the
Board of Directors of the Company.  The term "Trading Day" shall mean a day on
which the principal national securities exchange on which the Security is
listed or admitted to trading is open for the transaction of business or, if
the Security is not listed or admitted to trading on any national securities
exchange, a Business Day.

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





                                       16
<PAGE>   20
publicly traded but the Common Stock is publicly traded, the "current per share
market price" of the Preferred Stock shall be conclusively deemed to be the
current per share market price of the Common Stock as determined pursuant to
Section 11(d)(i) multiplied by the then applicable Adjustment Number (as
defined in and determined in accordance with the Certificate of Designation for
the Preferred Stock).  If neither the Common Stock nor the Preferred Stock is
publicly traded, "current per share market price" shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent.

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

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

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

              (h)     Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase Price as a
result of the calculations made in Sections 11(b) and 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-hundredth of a share of Preferred Stock (calculated to the nearest one
ten-thousandth of a share of Preferred Stock) obtained by (i) multiplying (x)
the number of one one-hundredths of a share purchasable upon the exercise of a
Right immediately prior to such adjustment by (y) the Purchase Price in effect
immediately prior to such





                                       17
<PAGE>   21
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

              (i)     The Company may elect on or after the date of any
adjustment of the Purchase Price pursuant to Sections 11(b) or 11(c) hereof to
adjust the number of Rights, in substitution for any adjustment in the number
of one one-hundredths of a share of Preferred Stock purchasable upon the
exercise of a Right.  Each of the Rights outstanding after such adjustment of
the number of Rights shall be exercisable for the number of one one-hundredths
of a share of Preferred Stock for which a Right was exercisable immediately
prior to such adjustment.  Each Right held of record prior to such adjustment
of the number of Rights shall become that number of Rights (calculated to the
nearest one-hundredth) obtained by dividing the Purchase Price in effect
immediately prior to adjustment of the Purchase Price by the Purchase Price in
effect immediately after adjustment of the Purchase Price.  The Company shall
make a public announcement of its election to adjust the number of Rights,
indicating the record date for the adjustment, and, if known at the time, the
amount of the adjustment to be made.  Such record date may be the date on which
the Purchase Price is adjusted or any day thereafter, but, if the Right
Certificates have been issued, shall be at least 10 days later than the date of
the public announcement.  If Right Certificates have been issued, upon each
adjustment of the number of Rights pursuant to this Section 11(i), the Company
may, as promptly as practicable, cause to be distributed to holders of record
of Right Certificates on such record date Right Certificates evidencing,
subject to Section 14 hereof, the additional Rights to which such holders shall
be entitled as a result of such adjustment, or, at the option of the Company,
shall cause to be distributed to such holders of record in substitution and
replacement for the Right Certificates held by such holders prior to the date
of adjustment, and upon surrender thereof, if required by the Company, new
Right Certificates evidencing all the Rights to which such holders shall be
entitled after such adjustment.  Right Certificates so to be distributed shall
be issued, executed and countersigned in the manner provided for herein and
shall be registered in the names of the holders of record of Right Certificates
on the record date specified in the public announcement.

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

              (k)     Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the fraction
of Preferred Stock or other shares of capital stock issuable upon exercise of a
Right, 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 shares of Preferred Stock or other such
shares at such adjusted Purchase Price.





                                       18
<PAGE>   22
              (l)     In any case in which this Section 11 shall require that
an adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event issuing to the holder of any Right exercised after such record date the
Preferred Stock and other capital stock or securities of the Company, if any,
issuable upon such exercise over and above the Preferred Stock and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment;
provided, however, that the Company shall deliver to such holder a due bill or
other appropriate instrument evidencing such holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

              (m)     Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such adjustments in the
Purchase Price, in addition to those adjustments expressly required by this
Section 11, as and to the extent that it in its sole discretion shall determine
to be advisable in order that any consolidation or subdivision of the Preferred
Stock, issuance wholly for cash of any shares of 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 for
Preferred Stock, dividends on Preferred Stock payable in shares of Preferred
Stock or issuance of rights, options or warrants referred to hereinabove in
Section 11(b), hereafter made by the Company to holders of its Preferred Stock
shall not be taxable to such stockholders.

              (n)     Anything in this Agreement to the contrary
notwithstanding, in the event that at any time after the date of this Rights
Agreement and prior to the Distribution Date, the Company shall (i) declare and
pay any dividend on the Common Stock payable in Common Stock or (ii) effect a
subdivision, combination or consolidation of the Common Stock (by
reclassification or otherwise than by payment of a dividend payable in Common
Stock) into a greater or lesser number of shares of Common Stock, then, in each
such case, the number of Rights associated with each share of Common Stock then
outstanding, or issued or delivered thereafter, shall be proportionately
adjusted so that the number of Rights thereafter associated with each share of
Common Stock following any such event shall equal the result obtained by
multiplying the number of Rights associated with each share of Common Stock
immediately prior to such event by a fraction the numerator of which shall be
the total number of shares of Common Stock outstanding immediately prior to the
occurrence of the event and the denominator of which shall be the total number
of shares of Common Stock outstanding immediately following the occurrence of
such event.

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

              Section 12.  Certificate of Adjusted Purchase Price or Number of
Shares.  Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Stock and the Preferred Stock a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with
Section 25 hereof (if so required under Section 25 hereof).  The Rights Agent
shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall not be deemed to have knowledge of any
such adjustment unless and until it shall have received such certificate.

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

              (a)     In the event, directly or indirectly, at any time after
the Flip-In Event (i) the Company shall consolidate with or shall merge into
any other Person, (ii) any Person shall merge with and into the Company and the
Company shall be the continuing or surviving corporation of such merger and, in
connection with such merger, all or part of the Common Stock shall be changed
into or exchanged for stock or other securities of any other Person (or of the
Company) or cash or any other property, or (iii) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one or more transactions, assets or earning power aggregating 50%
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person (other than the Company or one or more
wholly-owned Subsidiaries of the Company), then upon the first occurrence of
such event, proper provision shall be made so that: (A) each holder of a Right
(other than Rights which have become void pursuant to Section 11(a)(ii) hereof)
shall thereafter have the right to receive, upon the exercise thereof at the
Purchase Price (as theretofore adjusted in accordance with Section 11(a)(ii)
hereof), in accordance with the terms of this Agreement and in lieu of shares
of Preferred Stock or Common Stock of the Company, such number of validly
authorized and issued, fully paid, non-assessable and freely tradeable shares
of Common Stock of the Principal Party (as such term is hereinafter defined),
not subject to any liens, encumbrances, rights of first refusal or other
adverse claims, as shall equal the result obtained by dividing the Purchase
Price (as theretofore adjusted in accordance with Section 11(a)(ii) hereof) by
50% of the current per share market price of the Common Stock of such Principal
Party (determined pursuant to Section 11(d) hereof) on the date of consummation
of such consolidation, merger, sale or transfer; provided, however, that the
Purchase Price (as theretofore adjusted in accordance with Section 11(a)(ii)
hereof) and the number of shares of Common Stock of such Principal Party so
receivable upon exercise of a Right shall be subject to further adjustment as
appropriate in accordance with Section 11(f) hereof to reflect any events
occurring in respect of the Common Stock of such Principal Party after the
occurrence of such consolidation, merger, sale or transfer; (B) such Principal
Party shall thereafter be liable for, and shall assume, by virtue of such
consolidation, merger, sale or transfer, all the obligations and duties of the
Company pursuant to this Rights Agreement;





                                       20
<PAGE>   24
(C) the term "Company" shall thereafter be deemed to refer to such Principal
Party; and (D) such Principal Party shall take such steps (including, but not
limited to, the reservation of a sufficient number of its shares of Common
Stock in accordance with Section 9 hereof) in connection with such consummation
of any such transaction as may be necessary to assure that the provisions
hereof shall thereafter be applicable, as nearly as reasonably may be, in
relation to the shares of its Common Stock thereafter deliverable upon the
exercise of the Rights; provided that, upon the subsequent occurrence of any
consolidation, merger, sale or transfer of assets or other extraordinary
transaction in respect of such Principal Party, each holder of a Right shall
thereupon be entitled to receive, upon exercise of a Right and payment of the
Purchase Price as provided in this Section 13(a), such cash, shares, rights,
warrants and other property which such holder would have been entitled to
receive had such holder, at the time of such transaction, owned the Common
Stock of the Principal Party receivable upon the exercise of a Right pursuant
to this Section 13(a), and such Principal Party shall take such steps
(including, but not limited to, reservation of shares of stock) as may be
necessary to permit the subsequent exercise of the Rights in accordance with
the terms hereof for such cash, shares, rights, warrants and other property.

              (b)     "Principal Party" shall mean:

                      (i)      in the case of any transaction described in (i)
or (ii) of the first sentence of Section 13(a) hereof: (A) the Person that is
the issuer of the securities into which the shares of Common Stock are
converted in such merger or consolidation, or, if there is more than one such
issuer, the issuer the shares of Common Stock of which have the greatest
aggregate market value of shares outstanding, or (B) if no securities are so
issued, (x) the Person that is the other party to the merger, if such Person
survives said merger, or, if there is more than one such Person, the Person the
shares of Common Stock of which have the greatest aggregate market value of
shares outstanding or (y) if the Person that is the other party to the merger
does not survive the merger, the Person that does survive the merger (including
the Company if it survives) or (z) the Person resulting from the consolidation;
and

                      (ii)     in the case of any transaction described in
(iii) of the first sentence in Section 13(a) hereof, the Person that is the
party receiving the greatest portion of the assets or earning power transferred
pursuant to such transaction or transactions, or, if each Person that is a
party to such transaction or transactions receives the same portion of the
assets or earning power so transferred or if the Person receiving the greatest
portion of the assets or earning power cannot be determined, whichever of such
Persons is the issuer of Common Stock having the greatest aggregate market
value of shares outstanding; provided, however, that in any such case described
in the foregoing clause (b)(i) or (b)(ii), if the Common Stock of such Person
is not at such time or has not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, then (1) if such Person
is a direct or indirect Subsidiary of another Person the Common Stock of which
is and has been so registered, the term "Principal Party" shall refer to such
other Person, or (2) if such





                                       21
<PAGE>   25
Person is a Subsidiary, directly or indirectly, of more than one Person, the
Common Stock of all of which is and has been so registered, the term "Principal
Party" shall refer to whichever of such Persons is the issuer of Common Stock
having the greatest aggregate market value of shares outstanding, or (3) if
such Person is owned, directly or indirectly, by a joint venture formed by two
or more Persons that are not owned, directly or indirectly, by the same Person,
the rules set forth in clauses (1) and (2) above shall apply to each of the
owners having an interest in the venture as if the Person owned by the joint
venture was a Subsidiary of both or all of such joint venturers, and the
Principal Party in each such case shall bear the obligations set forth in this
Section 13 in the same ratio as its interest in such Person bears to the total
of such interests.

              (c)     The Company shall not consummate any consolidation,
merger, sale or transfer referred to in Section 13(a) hereof unless prior
thereto the Company and the Principal Party involved therein shall have
executed and delivered to the Rights Agent an agreement confirming that the
requirements of Sections 13(a) and (b) hereof shall promptly be performed in
accordance with their terms and that such consolidation, merger, sale or
transfer of assets shall not result in a default by the Principal Party under
this Agreement as the same shall have been assumed by the Principal Party
pursuant to Sections 13(a) and (b) hereof and providing that, as soon as
practicable after executing such agreement pursuant to this Section 13, the
Principal Party will:

                      (i)      prepare and file a registration statement under
the Securities Act, if necessary, with respect to the Rights and the securities
purchasable upon exercise of the Rights on an appropriate form, use its best
efforts to cause such registration statement to become effective as soon as
practicable after such filing and use its best efforts to cause such
registration statement to remain effective (with a prospectus at all times
meeting the requirements of the Securities Act) until the Expiration Date and
similarly comply with applicable state securities laws;

                      (ii)     use its best efforts, if the Common Stock of the
Principal Party shall be listed or admitted to trading on the New York Stock
Exchange or on another national securities exchange, to list or admit to
trading (or continue the listing of) the Rights and the securities purchasable
upon exercise of the Rights on the New York Stock Exchange or such securities
exchange, or, if the Common Stock of the Principal Party shall not be listed or
admitted to trading on the New York Stock Exchange or a national securities
exchange, to cause the Rights and the securities receivable upon exercise of
the Rights to be authorized for quotation on NASDAQ or on such other system
then in use;

                      (iii)    deliver to holders of the Rights historical
financial statements for the Principal Party which comply in all respects with
the requirements for registration on Form 10 (or any successor form) under the
Exchange Act; and





                                       22
<PAGE>   26
                      (iv)     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.

              (d)     In case the Principal Party has provision in any of its
authorized securities or in its certificate of incorporation or by-laws or
other instrument governing its corporate affairs, which provision would have
the effect of (i) causing such Principal Party to issue (other than to holders
of Rights pursuant to this Section 13), in connection with, or as a consequence
of, the consummation of a transaction referred to in this Section 13, shares of
Common Stock or Common Stock Equivalents of such Principal Party at less than
the then current market price per share thereof (determined pursuant to Section
11(d) hereof) or securities exercisable for, or convertible into, Common Stock
or Common Stock Equivalents of such Principal Party at less than such then
current market price, or (ii) providing for any special payment, tax or similar
provision in connection with the issuance of the Common Stock of such Principal
Party pursuant to the provisions of Section 13, then, in such event, the
Company hereby agrees with each holder of Rights that it shall not consummate
any such transaction unless prior thereto the Company and such Principal Party
shall have executed and delivered to the Rights Agent a supplemental agreement
providing that the provision in question of such Principal Party shall have
been canceled, waived or amended, or that the authorized securities shall be
redeemed, so that the applicable provision will have no effect in connection
with, or as a consequence of, the consummation of the proposed transaction.

              (e)     The Company covenants and agrees that it shall not, at
any time after the Flip-In Event, enter into any transaction of the type
described in clauses (i) through (iii) of Section 13(a) hereof if (i) at the
time of or immediately after such consolidation, merger, sale, transfer or
other transaction there are any rights, warrants or other instruments or
securities outstanding or agreements in effect which would substantially
diminish or otherwise eliminate the benefits intended to be afforded by the
Rights, (ii) prior to, simultaneously with or immediately after such
consolidation, merger, sale, transfer or other transaction, the stockholders of
the Person who constitutes, or would constitute, the Principal Party for
purposes of Section 13(b) hereof shall have received a distribution of Rights
previously owned by such Person or any of its Affiliates or Associates or (iii)
the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

              Section 14.  Fractional Rights and Fractional Shares.

              (a)     The Company shall not be required to issue fractions of
Rights or to distribute Right Certificates which evidence fractional Rights
(except prior to the Distribution Date in accordance with Section 11(n)
hereof).  In lieu of such fractional Rights, there shall be paid to the
registered holders of the Right Certificates with regard to which such
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right.  For the purposes
of this Section 14(a), the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day





                                       23
<PAGE>   27
immediately prior to the date on which such fractional Rights would have been
otherwise issuable.  The closing price for any day shall be the last sale
price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with
respect to securities listed or admitted to trading on the New York Stock
Exchange or, if the Rights are not listed or admitted to trading on the New
York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Rights are listed or admitted to trading or,
if the Rights are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by NASDAQ
or such other system then in use or, if on any such date the Rights are not
quoted by any such organization, the average of the closing bid and asked
prices as furnished by a professional market maker making a market in the
Rights selected by the Board of Directors of the Company.  If on any such date
no such market maker is making a market in the Rights, the fair value of the
Rights on such date as determined in good faith by the Board of Directors of
the Company shall be used.

              (b)     The Company shall not be required to issue fractions of
Preferred Stock (other than fractions which are integral multiples of one
one-hundredth of a share of Preferred Stock) or to distribute certificates
which evidence fractional shares of Preferred Stock (other than fractions which
are integral multiples of one one-hundredth of a share of Preferred Stock) upon
the exercise or exchange of Rights.  Interests in fractions of Preferred Stock
in integral multiples of one one-hundredth of a share of Preferred Stock may,
at the election of the Company, be evidenced by depositary receipts, pursuant
to an appropriate agreement between the Company and a depositary selected by
it; provided, that such agreement shall provide that the holders of such
depositary receipts shall have all the rights, privileges and preferences to
which they are entitled as beneficial owners of the Preferred Stock represented
by such depositary receipts.  In lieu of fractional shares of Preferred Stock
that are not integral multiples of one one-hundredth of a share of Preferred
Stock, the Company shall pay to the registered holders of Right Certificates at
the time such Rights are exercised or exchanged as herein provided an amount in
cash equal to the same fraction of the current market value of a whole share of
Preferred Stock (as determined in accordance with Section 14(a) hereof) for the
Trading Day immediately prior to the date of such exercise or exchange.

              (c)     The Company shall not be required to issue fractions of
shares of Common Stock or to distribute certificates which evidence fractional
shares of Common Stock upon the exercise or exchange of Rights.  In lieu of
such fractional shares of Common Stock, the Company shall pay to the registered
holders of the Right Certificates with regard to which such fractional shares
of Common Stock would otherwise be issuable an amount in cash equal to the same
fraction of the current market value of a whole share of Common Stock (as
determined in accordance with Section 14(a) hereof) for the Trading Day
immediately prior to the date of such exercise or exchange.





                                       24
<PAGE>   28
              (d)     The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise or exchange of a Right (except as provided above).

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

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

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

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

              (c)     the Company and the Rights Agent may deem and treat the
Person in whose name the Right Certificate (or, prior to the Distribution Date,
the 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 Right Certificates or the Common Stock certificate made by
anyone other than the Company or the Rights Agent) for all purposes whatsoever,
and neither the Company nor the Rights Agent shall be affected by any notice to
the contrary.

              Section 17.  Right Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Stock or any
other securities of the Company which may





                                       25
<PAGE>   29
at any time be issuable on the exercise or exchange of the Rights represented
thereby, nor shall anything contained herein or in any Right Certificate be
construed to confer upon the holder of any Right Certificate, as such, any of
the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in this Agreement), or to receive dividends or subscription rights, or
otherwise, until the Rights evidenced by such Right Certificate shall have been
exercised or exchanged in accordance with the provisions hereof.

              Section 18.  Concerning the Rights Agent.

              (a)     The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
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 or willful misconduct on the part of the Rights Agent, for anything done
or omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including the costs and expenses of defending
against any claim of liability arising therefrom, directly or indirectly.

              (b)     The Rights Agent shall be protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it in
connection with, its administration of this Agreement in reliance upon any
Right Certificate or certificate for the 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 believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

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

              (a)     Any corporation into which the Rights Agent or any
successor Rights Agent may be merged or with which it may be consolidated, or
any corporation resulting from any merger or consolidation to which the Rights
Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the stock transfer or corporate trust powers of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent under
this Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto; provided, that such corporation would
be eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof.  In case at the time such successor Rights Agent shall
succeed to the agency created by this Agreement, any of the





                                       26
<PAGE>   30
Right Certificates shall have been countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Right Certificates so countersigned; and in case at that
time any of the Right Certificates shall not have been countersigned, any
successor Rights Agent may countersign such Right Certificates either in the
name of the predecessor Rights Agent or in the name of the successor Rights
Agent; and in all such cases such Right Certificates shall have the full force
provided in the Right Certificates and in this Agreement.

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

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

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

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

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

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





                                       27
<PAGE>   31
              (e)     The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Right Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or
any adjustment in the terms of the Rights provided for in Sections 3, 11, 13,
23 and 24, or the ascertaining of the existence of facts that would require any
such change or adjustment (except with respect to the exercise of Rights
evidenced by Right Certificates after receipt of a certificate furnished
pursuant to Section 12, describing such change or adjustment); nor shall it by
any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any shares of Preferred Stock or other
securities to be issued pursuant to this Agreement or any Right Certificate or
as to whether any shares of Preferred 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 performing
by the Rights Agent of the provisions of this Agreement.

              (g)     The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder
from any person reasonably believed by the Rights Agent to be one of the
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 by it in good faith in accordance with
instructions of any such officer or for any delay in acting while waiting for
those instructions.  Any application by the Rights Agent for written
instructions from the Company may, at the option of the Rights Agent, set forth
in writing any action proposed to be taken or omitted by the Rights Agent under
this Agreement and the date on and/or after which such action shall be taken or
such omission shall be effective.  The Rights Agent shall not be liable for any
action taken by, or omission of, the Rights Agent in accordance with a proposal
included in any such application on or after the date specified in such
application (which date shall not be less than five Business Days after the
date any officer of the Company actually receives such application unless any
such officer shall have consented in writing to an earlier date) unless, prior
to taking any such action (or the effective date in the case of an omission),
the Rights Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted.

              (h)     The Rights Agent and any stockholder, director, officer
or employee of the Rights Agent may buy, sell or deal in any of the Rights or
other securities of the Company or become pecuniarily interested in any
transaction in which the Company may be interested, or contract with or lend
money to the Company or otherwise act as fully and freely as though it





                                       28
<PAGE>   32
were not Rights Agent under this Agreement.  Nothing herein shall preclude the
Rights Agent from acting in any other capacity for the Company or for any other
legal entity.

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

              (j)     If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate contained in the
form of assignment or the form of election to purchase set forth on the reverse
thereof, as the case may be, has not been completed to certify the holder is
not an Acquiring Person (or an Affiliate or Associate thereof), the Rights
Agent shall not take any further action with respect to such requested exercise
or transfer without first consulting with the Company.

              Section 21.  Change of Rights Agent.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Stock or Preferred Stock by registered or
certified mail, and, following the Distribution Date, to the holders of the
Right Certificates by first-class mail.  The Company may remove the Rights
Agent or any successor Rights Agent upon 30 days' notice in writing, mailed to
the Rights Agent or successor Rights Agent, as the case may be, and to each
transfer agent of the Common Stock or Preferred Stock by registered or
certified mail, and, following the Distribution Date, to the holders of the
Right Certificates by first-class mail.  If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall
appoint a successor to the Rights Agent.  If the Company shall fail to make
such appointment within a period of 30 days after giving notice of such removal
or after it has been notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the holder of a Right
Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Company), then the registered holder of any Right Certificate
may apply to any court of competent jurisdiction for the appointment of a new
Rights Agent.  Any successor Rights Agent, whether appointed by the Company or
by such a court, shall be a corporation organized and doing business under the
laws of the United States or the laws of any state of the United States or the
District of Columbia, in good standing, having an office in the State of
Illinois, which is authorized under such laws to exercise corporate trust or
stock transfer powers and is subject to supervision or examination by federal
or state authority and which has at the time of its appointment as Rights Agent
a combined capital and surplus of at least $50 million.  After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and
transfer to the successor Rights Agent any property at the time held by it
hereunder, and execute and





                                       29
<PAGE>   33
deliver any further assurance, conveyance, act or deed necessary for the
purpose.  Not later than the effective date of any such appointment the Company
shall file notice thereof in writing with the predecessor Rights Agent and each
transfer agent of the Common Stock or Preferred Stock, and, following the
Distribution Date, mail a notice thereof in writing to the registered holders
of the Right Certificates.  Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

              Section 22.  Issuance of New Right Certificates.  Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such forms as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Agreement.  In addition, in
connection with the issuance or sale of Common Stock following the Distribution
Date and prior to the Expiration Date, the Company may with respect to shares
of Common Stock so issued or sold pursuant to (i) the exercise of stock
options, (ii) under any employee plan or arrangement, (iii) upon the exercise,
conversion or exchange of securities, notes or debentures issued by the Company
or (iv) a contractual obligation of the Company, in each case existing prior to
the Distribution Date, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale.

              Section 23.  Redemption.

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

              (b)     Immediately upon the action of the Board of Directors
ordering the redemption of the Rights pursuant to paragraph (a) of this Section
23 (or at such later time as the Board of Directors may establish for the
effectiveness of such redemption), and without any further action and without
any notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
The Company shall promptly give public notice of any such redemption; provided,
however, that the failure to give, or any defect in, any such notice shall not
affect the validity of such redemption.  Within 10 days after such action of
the Board of Directors ordering the





                                       30
<PAGE>   34
redemption of the Rights (or such later time as the Board of Directors may
establish for the effectiveness of such redemption), the Company shall mail a
notice of redemption to all the holders of the then outstanding Rights at their
last addresses as they appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Stock.  Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice.  Each
such notice of redemption shall state the method by which the payment of the
Redemption Price will be made.

              Section 24.  Exchange.

              (a)     The Board of Directors of the Company may, at its option,
at any time after the Flip-In Event, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to the provisions of Section 11(a)(ii) hereof) for Common
Stock at an exchange ratio of one share of Common Stock per Right,
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such amount per Right being
hereinafter referred to as the "Exchange Ratio").  Notwithstanding the
foregoing, the Board of Directors shall not be empowered to effect such
exchange at any time after an Acquiring Person shall have become the Beneficial
Owner of shares of Common Stock aggregating 50% or more of the shares of Common
Stock then outstanding.  From and after the occurrence of an event specified in
Section 13(a) hereof, any Rights that theretofore have not been exchanged
pursuant to this Section 24(a) shall thereafter be exercisable only in
accordance with Section 13 and may not be exchanged pursuant to this Section
24(a).  The exchange of the Rights by the Board of Directors may be made
effective at such time, on such basis and with such conditions as the Board of
Directors in its sole discretion may establish.

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





                                       31
<PAGE>   35
              (c)     The Company may at its option substitute, and, in the
event that there shall not be sufficient shares of Common Stock issued but not
outstanding or authorized but unissued to permit an exchange of Rights for
Common Stock as contemplated in accordance with this Section 24, the Company
shall substitute to the extent of such insufficiency, for each share of Common
Stock that would otherwise be issuable upon exchange of a Right, a number of
shares of Preferred Stock or fraction thereof (or equivalent preferred shares,
as such term is defined in Section 11(b)) such that the current per share
market price (determined pursuant to Section 11(d) hereof) of one share of
Preferred Stock (or equivalent preferred share) multiplied by such number or
fraction is equal to the current per share market price of one share of Common
Stock (determined pursuant to Section 11(d) hereof) as of the date of such
exchange.

              Section 25.  Notice of Certain Events.

              (a)     In case the Company shall at any time after the earlier
of the Distribution Date or the Stock Acquisition Date propose (i) to pay any
dividend payable in stock of any class to the holders of its Preferred Stock or
to make any other distribution to the holders of its Preferred Stock (other
than a regular quarterly cash dividend), (ii) to offer to the holders of its
Preferred Stock rights or warrants to subscribe for or to purchase any
additional shares of Preferred Stock or shares of stock of any class or any
other securities, rights or options, (iii) to effect any reclassification of
its Preferred Stock (other than a reclassification involving only the
subdivision or combination of outstanding Preferred Stock), (iv) to effect the
liquidation, dissolution or winding up of the Company, or (v) to pay any
dividend on the Common Stock payable in Common Stock or to effect a
subdivision, combination or consolidation of the Common Stock (by
reclassification or otherwise than by payment of dividends in Common Stock),
then, in each such case, the Company shall give to each holder of a Right
Certificate, in accordance with Section 26 hereof, a notice of such proposed
action, which shall specify the record date for the purposes of such stock
dividend, or distribution of rights or warrants, or the date on which such
liquidation, dissolution or winding up is to take place and the date of
participation therein by the holders of the Common Stock and/or Preferred
Stock, if any such date is to be fixed, and such notice shall be so given in
the case of any action covered by clause (i) or (ii) above at least 10 days
prior to the record date for determining holders of the Preferred Stock for
purposes of such action, and in the case of any such other action, at least 10
days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Common Stock and/or Preferred
Stock, whichever shall be the earlier.

              (b)     In case any event described in Section 11(a)(ii) or
Section 13 shall occur then the Company shall as soon as practicable thereafter
give to each holder of a Right Certificate (or if occurring prior to the
Distribution Date, the holders of the Common Stock) in accordance with Section
26 hereof, a notice of the occurrence of such event, which notice shall
describe such event and the consequences of such event to holders of Rights
under Section 11(a)(ii) and Section 13 hereof.

              Section 27.  Supplements and Amendments.  Except as provided in
the penultimate sentence of this Section 27, for so long as the Rights are then
redeemable, the Company may in its sole and absolute discretion, and the Rights
Agent shall if the Company so directs, supplement or amend any provision of
this Agreement in any respect without the approval of any holders of the
Rights.  At any time when the Rights are no longer redeemable, except as

the Rights Agent shall, if the Company so directs, supplement or amend this
Agreement without the approval of any holders of Rights in order to (i) cure

interests of the holders of Rights as such (other than an Acquiring Person or
an Affiliate or Associate of an Acquiring Person), and no such amendment may
cause the Rights again to become redeemable or cause the Agreement again to
become amendable other than in accordance with this sentence.  Notwithstanding
anything contained in this Agreement to the contrary, no supplement or
amendment shall be made which changes the Redemption Price.  Upon the delivery
of a certificate from an appropriate officer of the Company which states that
the proposed supplement or amendment is in compliance with the terms of this
Section 27, the Rights Agent shall execute such supplement or amendment.

              Section 28.  Successors.  All the covenants and provisions of

bind and inure to the benefit of their respective successors and assigns
hereunder.

Agreement shall be construed to give to any Person other than the Company, the
Rights Agent and the registered holders of the Right Certificates (and, prior

remedy or claim under this Agreement; but this Agreement shall be for the sole
and exclusive benefit of the Company, the Rights Agent and the registered
holders of the Right Certificates (and, prior to the Distribution Date, the
Common Stock).

              Section 30.  Determinations and Actions by the Board of
Directors.  The Board of Directors of the Company shall have the exclusive
power and authority to administer this Agreement and to exercise the rights and
powers specifically granted to the Board of Directors of the Company or to the
Company, or as may be necessary or advisable in the administration of this
Agreement, including, without limitation, the right and power to (i) interpret
the provisions of this Agreement and (ii) make all determinations deemed
necessary or advisable for the administration of this Agreement (including,
without limitation, a determination to redeem or not redeem the Rights or to
amend this Agreement).  All such actions, calculations, interpretations and
determinations (including, for purposes of clause (y) below, all omissions with
respect to the foregoing) that are done or made by the Board of Directors of
the Company in good faith, shall (x) be final, conclusive and binding on the
Company, the Rights Agent, the holders of the Rights, as such, and all other
parties, and (y) not subject the Board of Directors to any liability to the
holders of the Rights.

              Section 31.  Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

              Section 32.  Governing Law.  This Agreement and each Right
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and

                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                                 TELTREND INC.

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

              Teltrend Inc., a corporation organized and existing under the
General Corporation Law of the State of Delaware, in accordance with the
provisions of Section 103 thereof, DOES HEREBY CERTIFY:

              That pursuant to the authority vested in the Board of Directors
in accordance with the provisions of the Certificate of Incorporation of the
said Corporation, the said Board of Directors on January 16, 1997 adopted the
following resolution creating a series of 80,000 shares of Preferred Stock
designated as "Series A Junior Participating Preferred Stock":

                      RESOLVED, that pursuant to the authority vested in the
              Board of Directors of this Corporation in accordance with the
              provisions of the Certificate of Incorporation, a series of
              Preferred Stock, par value $.01 per share, of the Corporation be

              shares thereof and the voting and other powers, preferences and

              of such series and the qualifications, limitations and
              restrictions thereof are as follows:

                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

              1.      Designation and Amount.  There shall be a series of
Preferred Stock that shall be designated as "Series A Junior Participating
Preferred Stock," and the number of shares constituting such series shall be
80,000.  Such number of shares may be increased or decreased by resolution of
the Board of Directors; provided, however, that no decrease shall reduce the
number of shares of Series A Junior Participating  Preferred Stock to less than
the number of shares then issued and outstanding plus the number of shares
issuable upon exercise





                                      A-1
<PAGE>   41
of outstanding rights, options or warrants or upon conversion of outstanding
securities issued by the Corporation.

              2.      Dividends and Distribution.

                      (A)      Subject to the prior and superior rights of the
holders of any shares of any class or series of stock of the Corporation
ranking prior and superior to the shares of Series A Junior Participating
Preferred Stock with respect to dividends, the holders of shares of Series A
Junior Participating  Preferred Stock, in preference to the holders of shares
of any class or series of stock of the Corporation ranking junior to the Series
A Junior Participating Preferred Stock in respect thereof, shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds
legally available for the purpose, quarterly dividends payable in cash on the
first day of April, July, October and January, in each year (each such date
being referred to herein as a "Quarterly Dividend Payment Date"), commencing on
the first Quarterly Dividend Payment Date after the first issuance of a share
or fraction of a share of Series A Junior Participating Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the greater of (a) $.05
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, par value $.01 per share, of the Corporation (the "Common
Stock") since the immediately preceding Quarterly Dividend Payment Date, or,
with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Junior Participating
Preferred Stock.  The "Adjustment Number" shall initially be 100.  In the event
the Corporation shall at any time after January 16, 1997 (the "Rights
Declaration Date") (i) declare and pay any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the 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 Junior Participating Preferred Stock as provided
in paragraph (A) above immediately after it declares a dividend or distribution
on the Common Stock (other than a dividend payable in shares of Common Stock).

                      (C)      Dividends shall begin to accrue and be
cumulative on outstanding shares of Series A Junior Participating Preferred
Stock from the Quarterly Dividend Payment Date next preceding the date of issue
of such shares of Series A Junior Participating Preferred Stock, unless the
date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such shares shall
begin to accrue from the date of issue of such shares, or unless the date of
issue is a Quarterly





                                      A-2
<PAGE>   42
Dividend Payment Date or is a date after the record date for the determination
of holders of shares of Series A Junior Participating Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment
Date, in either of which events such dividends shall begin to accrue and be
cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid
dividends shall not bear interest.  Dividends paid on the shares of Series A
Junior Participating Preferred Stock in an amount less than the total amount of
such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding.  The Board of Directors may fix a record date for the
determination of holders of shares of Series A Junior Participating Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 60 days prior to the date
fixed for the payment thereof.

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

                      (A)      Each share of Series A Junior Participating
Preferred Stock shall entitle the holder thereof to a number of votes equal to
the Adjustment Number on all matters submitted to a vote of the stockholders of
the Corporation.

                      (B)      Except as required by law and by Section 10
hereof, holders of Series A Junior Participating 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.

              4.      Certain Restrictions.

                      (A)      Whenever quarterly dividends or other dividends
or distributions payable on the Series A Junior Participating 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 Junior Participating Preferred Stock outstanding shall have been paid
in full, the Corporation shall not:

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

                               (ii)    declare or pay dividends on or make any
other distributions on any shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Series A
Junior Participating Preferred Stock, except dividends paid ratably on the
Series A Junior Participating Preferred Stock and all such parity





                                      A-3
<PAGE>   43
stock on which dividends are payable or in arrears in proportion to the total
amounts to which the holders of all such shares are then entitled; or

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

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

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

                      6.       Liquidation, Dissolution or Winding Up. (A) Upon
any liquidation, dissolution or winding up of the Corporation, voluntary or
otherwise, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating Preferred Stock
shall have received an amount per share (the "Series A Liquidation Preference")
equal to the greater of (i) $160.00 plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment, or (ii) the Adjustment Number times the per share amount of all
cash and other property to be distributed in respect of the Common Stock upon
such liquidation, dissolution or winding up of the Corporation.

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





                                      A-4
<PAGE>   44
                               (C)     Neither the merger or consolidation of
the Corporation into or with another corporation nor the merger or
consolidation of any other corporation into or with the Corporation shall be
deemed to be a liquidation, dissolution or winding up of the Corporation within
the meaning of this Section 6.

                      7.       Consolidation, Merger, Etc.  In case the
Corporation shall enter into any consolidation, merger, combination or other
transaction in which the outstanding shares of Common Stock are exchanged for
or changed into other stock or securities, cash and/or any other property, then
in any such case each share of Series A Junior Participating Preferred Stock
shall at the same time be similarly exchanged or changed in an amount per share
equal to the Adjustment Number times the aggregate amount of stock, securities,
cash and/or any other property (payable in kind), as the case may be, into
which or for which each share of Common Stock is changed or exchanged.

                      8.       No Redemption.  Shares of Series A Junior
Participating Preferred Stock shall not be subject to redemption by the
Company.

                      9.       Ranking.  The Series A Junior Participating
Preferred Stock shall rank junior to all other series of the Preferred Stock as
to the payment of dividends and as to the distribution of assets upon
liquidation, dissolution or winding up, unless the terms of any such series
shall provide otherwise, and shall rank senior to the Common Stock as to such
matters.

                      10.      Amendment.  At any time that any shares of
Series A Junior Participating Preferred Stock are outstanding, the Restated
Certificate of Incorporation of the Corporation shall not be amended in any
manner which would materially alter or change the powers, preferences or
special rights of the Series A Junior Participating Preferred Stock so as to
affect them adversely without the affirmative vote of the holders of two-thirds
of the outstanding shares of Series A Junior Participating Preferred Stock,
voting separately as a class.

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

                         SUMMARY OF RIGHTS TO PURCHASE
                          SHARES OF PREFERRED STOCK OF
                                 TELTREND INC.

              On January 16, 1997, the Board of Directors of Teltrend Inc. (the
"Company") declared a dividend of one preferred share purchase right (a
"Right") for each outstanding share of common stock, par value $.01 per share,
of the Company (the "Common Stock").  The dividend is payable on January 27,
1997 (the "Record Date") to the holders of record of the Common Stock as of the
close of business on that date.  Each Right entitles the registered holder to
purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share, of the Company (the
"Preferred Stock") at a price of $160.00 per one one-hundredth of a share of
Preferred Stock (the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement dated as of January
16, 1997, as the same may be amended from time to time (the "Rights
Agreement"), between the Company and LaSalle National Bank, as Rights Agent
(the "Rights Agent").

              Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions, an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding shares of Common Stock or (ii) 10 business days
(or such later date as may be determined by action of the Board of Directors
prior to such time as any person or group of affiliated persons becomes an
Acquiring Person) following the commencement of, or announcement of an
intention to make, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of 15% or more of
the outstanding shares of Common Stock (the earlier of such dates being called
the "Distribution Date"), the Rights will be evidenced, with respect to any of
the Common Stock certificates outstanding as of the Record Date, by such Common
Stock certificate together with a copy of this Summary of Rights.

              The Rights Agreement provides that, until the Distribution Date
(or earlier expiration of the Rights), the Rights will be transferred with and
only with the Common Stock.  Until the Distribution Date (or earlier expiration
of the Rights), new Common Stock





                                      C-1

certificates issued after the Record Date upon transfer or new issuances of
Common Stock will contain a notation incorporating the Rights Agreement by
reference.  Until the Distribution Date (or earlier expiration of the Rights),
the surrender for transfer of any certificates for shares of Common Stock
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights, will also constitute the transfer of the Rights associated
with the shares of Common Stock 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 Stock as of the close of business on the Distribution Date and such
separate Right Certificates alone will evidence the Rights.

              The Rights are not exercisable until the Distribution Date.  The
Rights will expire on January 16, 2007 (the "Final Expiration Date"), unless
the Final Expiration Date is advanced or extended or unless the Rights are
earlier redeemed or exchanged by the Company, in each case as described below.

              The Purchase Price payable, and the number of shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights is
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-current market price of the Preferred Stock or (iii) upon
the distribution to holders of the Preferred Stock of evidences of indebtedness
or assets (excluding regular periodic cash dividends or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

              The number of outstanding Rights is subject to adjustment in the
event of a stock dividend on the Common Stock payable in shares of Common Stock
or subdivisions, consolidations or combinations of the Common Stock occurring,
in any such case, prior to the Distribution Date.

              Shares of Preferred Stock purchasable upon exercise of the Rights
will not be redeemable.  Each share of Preferred Stock will be entitled, when,
as and if declared, to a minimum preferential quarterly dividend payment of
$.05 per share but will be entitled to an aggregate dividend of 100 times the
dividend declared per share of Common Stock.  In the event of liquidation,
dissolution or winding up of the Company, the holders of the Preferred Stock
will be entitled to a minimum preferential payment of $160.00 per share (plus
any accrued but unpaid dividends) but will be entitled to an aggregate payment
of 100 times the payment made per share of Common Stock.  Each share of
Preferred Stock will have 100 votes, voting together with the Common Stock.
Finally, in the event of any merger, consolidation or other transaction in
which outstanding shares of Common Stock are converted or exchanged, each share
of Preferred Stock will be entitled to receive 100 times the amount





                                      C-2

received per share of Common Stock.  These rights are protected by customary
antidilution provisions.

              Because of the nature of the Preferred Stock's dividend,
liquidation and voting rights, the value of the one one-hundredth interest in a
share of Preferred Stock purchasable upon exercise of each Right should
approximate the value of one share of Common Stock.

              In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right that number
of shares of Common Stock having a market value of two times the exercise price
of the Right.

              In the event that, after a person or group has become an
Acquiring Person, the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold, proper provisions will be made so that each holder of a Right
(other than Rights beneficially owned by an Acquiring Person which will have
become void) will thereafter have the right to receive upon the exercise of a
Right that number of shares of common stock of the person with whom the Company
has engaged in the foregoing transaction (or its parent) that at the time of
such transaction have a market value of two times the exercise price of the
Right.

              At any time after any person or group becomes an Acquiring Person
and prior to the earlier of one of the events described in the previous
paragraph or the acquisition by such Acquiring Person of 50% or more of the
outstanding shares of Common Stock, the Board of Directors of the Company may
exchange the Rights (other than Rights owned by such Acquiring Person which
will have become void), in whole or in part, for shares of Common Stock or
Preferred Stock (or a series of the Company's preferred stock having equivalent
rights, preferences and privileges), at an exchange ratio of one share of
Common Stock (subject to customary anti-dilution provisions), or a fractional
share of Preferred Stock (or other preferred stock) equivalent in value
thereto, per Right.

              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 shares of Preferred Stock or Common
Stock will be issued (other than fractions of Preferred Stock which are
integral multiples of one one-hundredth of a share of Preferred Stock, 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 current market
price of the Preferred Stock or the Common Stock.

              At any time prior to the time an Acquiring Person becomes 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").  The redemption
of the Rights may be made effective at





                                      C-3
<PAGE>   55
such time, on such basis and with such conditions as the Board of Directors in
its sole discretion may establish.  Immediately upon any redemption of the
Rights, the right to exercise the Rights will terminate and the only right of
the holders of Rights will be to receive the Redemption Price.

              For so long as the Rights are then redeemable, the Company may,
except with respect to the Redemption Price, amend the Rights Agreement in any
manner.  After the Rights are no longer redeemable, the Company generally may,
except with respect to the Redemption Price, amend the Rights Agreement in any
manner that does not adversely affect the interests of holders of the Rights.

              Until a Right is exercised or exchanged, 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 a Registration Statement on Form 8-A
dated January 27, 1997.  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, as the same may be amended from time to time, which is hereby
incorporated herein by reference.
