                                RIGHTS AGREEMENT

         Agreement, dated as of September 12, 2000, between NETsilicon, Inc., a
Massachusetts corporation (the "Company"), and American Stock Transfer and Trust
Company as rights agent (the "Rights Agent").

         WHEREAS, effective September 12, 2000, 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, par value $.01 per share, of
the Company (the "Common Stock") outstanding on the Close of Business on
September 23, 2000 (the "Record Date") and has authorized the issuance of one
Right with respect to each additional share of Common Stock that shall become
outstanding between the Record Date and the earliest of Close of Business on the
Distribution Date, the Redemption Date and the Close of Business on the Final
Expiration Date, each Right representing the right to purchase one
one-thousandth of a Preferred Share (as hereinafter defined), or such different
amount and/or kind of securities as shall be hereinafter provided.

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

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

         "Acquiring Person" shall mean any Person who or which, together with
all Affiliates and Associates of such Person, shall be the Beneficial Owner of
15% or more of the shares of Voting Stock of the Company then outstanding, or in
the case of the Grandfathered Stockholder, becomes the Beneficial Owner after
the date of this Agreement of an additional 1% or more of the shares of Voting
Stock of the Company then outstanding, but shall not include (i) the Company,
(ii) any Subsidiary of the Company, (iii) any employee benefit plan of the
Company or any Subsidiary of the Company, or (iv) any entity holding Voting
Stock for or pursuant to the terms of any such employee benefit plan.
Notwithstanding the foregoing:

                  (1) no Person shall become an "Acquiring Person" as the result
         of an acquisition of shares of Voting Stock by the Company which, by
         reducing the number of shares outstanding, increases the proportionate
         number of shares beneficially owned by such Person to 15% (or such
         other percentage as would otherwise result in such person becoming an
         Acquiring Person) or more of the shares of Voting Stock of the Company
         then outstanding; provided, however, that if a Person shall so become
         the Beneficial Owner of 15% (or such other percentage) or more of the
         shares of Voting Stock of the Company then outstanding by reason of an
         acquisition of shares of Voting Stock by the Company and shall, after
         such share purchases by the Company, become the Beneficial Owner of an
         additional 1% of the outstanding shares of Voting Stock of the Company,
         then such Person shall be deemed to be an "Acquiring Person"; and



                                       1
<PAGE>   5
                  (2) if the Board of Directors of the Company determines in
         good faith that a Person who would otherwise be an "Acquiring Person,"
         as defined pursuant to the foregoing provisions of this paragraph, has
         become such inadvertently and without any plan or intention to seek or
         affect control of the Company, and such Person enters into an
         irrevocable commitment with the Company to divest, and thereafter
         divests in accordance with the terms of such commitment a sufficient
         number of shares of Voting Stock so that such Person would no longer be
         an "Acquiring Person," as defined pursuant to the foregoing provisions
         of this paragraph, then such Person shall not be deemed to have become
         an "Acquiring Person" for any purposes of this Agreement.

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

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

                  (i) which such Person or any of such Person's Affiliates or
         Associates beneficially owns, directly or indirectly, for purposes of
         Section 13(d) of the Exchange Act and Rule 13d-3 of the Exchange Act
         Regulations (or any comparable or successor law or regulation);

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

                  (iii) which are beneficially owned, directly or indirectly, by
         any other Person (or any Affiliate or Associate thereof) with which
         such Person or any of such Person's Affiliates or Associates has any
         agreement, arrangement or understanding (other than


                                       2
<PAGE>   6
         customary agreements with and between underwriters and selling group
         members with respect to a bona fide public offering of securities),
         written or otherwise, for the purpose of acquiring, holding, voting
         (except to the extent contemplated by the proviso to section (B) of the
         immediately preceding paragraph (ii)) or disposing of any securities of
         the Company; provided, however, that in no case shall an officer or
         director of the Company be deemed (A) the Beneficial Owner of any
         securities beneficially owned by another officer or director of the
         Company solely by reason of actions undertaken by such persons in their
         capacity as officers or directors of the Company or (B) the Beneficial
         Owner of securities held of record by the trustee of any employee
         benefit plan of the Company or any Subsidiary of the Company for the
         benefit of any employee of the Company or any Subsidiary of the
         Company, other than the officer or director, by reason of any influence
         that such officer or director may have over the voting of the
         securities held in the plan.

the contrary, the phrase "then outstanding," when used with reference to a

the Company will send a copy of 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, 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 Close of Business on the Distribution Date, the
Rights will be evidenced by such certificates registered in the names of the
holders thereof together with a copy of the Summary of Rights attached thereto.
Until the Close of Business on the Distribution Date (or the earlier of the
Redemption Date or the Close of Business on the Final 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 attached thereto,
shall also constitute the transfer of the Rights associated with the Common
Stock evidenced thereby.

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

                  This certificate also evidences and entitles the holder hereof
                  to certain Rights as set forth in a Rights Agreement between
                  NETsilicon, Inc. and American Stock Transfer and Trust
                  Company, dated as of September 12, 2000 (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 NETsilicon, Inc. 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. NETsilicon, Inc. 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 that are or were acquired or
                  beneficially owned by Acquiring Persons (as defined in the
                  Rights Agreement) may become null and void.

With respect to such certificates containing the foregoing legend, until the
Close of Business on the Distribution Date, the Rights associated with the
Common Stock represented by certificates


                                       6
<PAGE>   10
shall be evidenced by such certificates alone, and the surrender for transfer of
any such certificate shall also constitute the transfer of the Rights associated
with the Common Stock represented thereby. In the event that the Company
purchases or acquires any Common Stock after the Record Date but prior to the
Close of Business on 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.

         Section 4. Form of Right Certificates. The Right Certificates (and the
forms of election to purchase Preferred Shares and of assignment to be printed
on the reverse thereof) shall be substantially the same as Exhibit B hereto and
may have such marks of identification or designation and such legends, summaries
or endorsements printed thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or transaction
reporting system on which the Rights may from time to time be listed, or to
conform to usage. Subject to the other provisions of this Agreement, the Right
Certificates shall entitle the holders thereof to purchase such number of one
one-thousandths of a Preferred Share as shall be set forth therein at the
Purchase Price, but the number of one one-thousandths of a Preferred Share and
the Purchase Price shall be subject to adjustment as provided herein.
Notwithstanding anything else set forth in this Agreement, no Distribution Date
shall be deemed to have occurred solely by reason of the execution and delivery
or amendment of the Merger Agreement, the Contribution Agreement or the Stock
Option Agreements and the transactions contemplated thereby.

         Section 5. Countersignature and Registration.

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

                  (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at its principal office, books for registration of the
transfer of the Right Certificates issued


                                       7
<PAGE>   11
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 Section 14 hereof, at any
time after the Close of Business on the Distribution Date, and prior to the
earlier of the Redemption Date or the Close of Business on the Final Expiration
Date, any Right Certificate or Right Certificates (other than Right Certificates
representing Rights that have become void pursuant to Section 11(a)(ii) hereof
or that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Right Certificate or Right
Certificates, entitling the registered holder to purchase a like number of one
one-thousandths of a Preferred Share as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any Right Certificate
or Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient for
any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

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

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

                  (a) The registered holder of any Right Certificate (other than
a holder whose Rights have become void pursuant to Section 11(a)(ii) hereof or
have been exchanged pursuant to Section 24 hereof) may exercise the Rights
evidenced thereby in whole or in part at any time after the Distribution Date
upon surrender of the Right Certificate, with the form of election to purchase
on the reverse side thereof duly executed, to the Rights Agent at its principal
office, together with payment of the Purchase Price for each one one-thousandth
of a Preferred Share as to which the Rights are exercised, prior to the earliest
of (i) the Close of Business on the Final Expiration Date or (ii) the closing
date of the transactions contemplated by the Merger Agreement.



                                       8
<PAGE>   12
                  (b) The purchase price for each one one-thousandth of a
Preferred Share to be purchased upon the exercise of a Right shall initially be
Two-Hundred Dollars ($200.00) (the "Purchase Price"), 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) below.

                  (c) Upon receipt of a Right Certificate representing
exercisable Rights, with the form of election to purchase and certificate duly
executed, accompanied by payment of the Purchase Price for the number of one
one-thousandths of a Preferred Share 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 Shares certificates for the number of one one-thousandths of a
Preferred Share to be purchased and the Company hereby irrevocably authorizes
its transfer agent to comply with all such requests, or (B) requisition from any
depository agent for the Preferred Shares depository receipts representing such
number of one one-thousandths of a Preferred Share as are to be purchased (in
which case certificates for the Preferred Shares represented by such receipts
shall be deposited by the transfer agent with the depository agent) and the
Company hereby directs the depository 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 Preferred Shares in accordance with Section 14
hereof, (iii) after receipt of such certificates or depository receipts, cause
the same to be delivered to or upon the order of the registered holder of such
Right Certificate, registered in such name or names as may be designated by such
holder and (iv) when appropriate, after receipt, deliver such cash to or upon
the order of the registered holder of such Right Certificate.

                  (d) In case the registered holder of any Right Certificate
shall exercise less than all the Rights evidenced thereby, a new Right
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to the registered holder of such Right
Certificate or to such registered holder's 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 upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall have (i) completed and signed the certificate contained in the form
of election to purchase set forth on the reverse side of the Right Certificate
surrendered for such exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request.

         Section 8. Cancellation and Destruction of Right Certificates. All
Right Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for


                                       9
<PAGE>   13
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 Rights Agreement.
The Company shall deliver to the Rights Agent for cancellation and retirement,
and the Rights Agent shall so cancel and retire, any other Right Certificate
purchased or acquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all 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. Status and Availability of Preferred Shares.

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

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

                  (c) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept available, out of its authorized and
unissued Preferred Shares or any Preferred Shares held in its treasury, the
number of Preferred Shares that will be sufficient to permit the exercise in
full of all outstanding Rights in accordance with Section 7 hereof. Upon the
occurrence of any events resulting in an increase in the aggregate number of
shares of Preferred Stock (or other equity securities of the Company) issuable
upon exercise of all outstanding Rights above the number then reserved, the
Company shall make appropriate increases in the number of shares so reserved.

         Section 10. Preferred Shares Record Date. Each person in whose name any
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares represented thereby on, and such certificate shall be dated, the date
upon which the Right Certificate evidencing such Rights was duly surrendered and
payment of the Purchase Price (and any applicable transfer taxes) was made.
Prior to the exercise of the Rights evidenced thereby, the holder of a Right
Certificate shall not be entitled to any rights of a holder of Preferred Shares
for which the Rights shall be exercisable, including, without limitation, the
right to vote, to receive dividends or other


                                       10
<PAGE>   14
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

         Section 11. Adjustment of Purchase Price, Number of Shares or Number of
Rights. The Purchase Price, the number of Preferred Shares covered by each Right
and the number of Rights outstanding are subject to adjustment from time to time
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 a dividend on the Preferred Shares
payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C)
combine the outstanding Preferred Shares into a smaller number of Preferred
Shares or (D) issue any shares of its capital stock in a reclassification of the
Preferred Shares (including any such reclassification in connection with a
consolidation or merger in which the Company is the continuing or surviving
corporation), except as otherwise provided in this Section 11(a), the Purchase
Price in effect at the time of the record date for such dividend or 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, such 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.
If an event occurs which would require an adjustment under both this Section
11(a)(i) and Section 11(a)(ii), the adjustment provided for in this Section
11(a)(i) shall be in addition to, and shall be made prior, to any adjustment
required pursuant to Section 11(a)(ii).

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

         From and after the occurrence of such an event, any Rights that are or
were acquired or beneficially owned by such Acquiring Person (or any Associate
or Affiliate of such Acquiring Person) on or after the earlier of (x) the date
of such event and (y) the Distribution Date shall be void and any holder of such
Rights shall thereafter have no right to exercise such Rights under


                                       11
<PAGE>   15
any provision of this Agreement. No Right Certificate shall be issued pursuant
to Section 3 that represents Rights beneficially owned by an Acquiring Person
whose Rights would be void pursuant to the preceding sentence or any Associate
or Affiliate thereof; no Right Certificate shall be issued at any time upon the
transfer of any Rights to an Acquiring Person whose Rights would be void
pursuant to the preceding sentence or any Associate or Affiliate thereof or to
any nominee of such Acquiring Person, Associate or Affiliate; and any Right
Certificate delivered to the Rights Agent for transfer to an Acquiring Person
whose Rights would be void pursuant to the preceding sentence or any Associate
or Affiliate thereof shall be canceled.

                           (iii) In the event that the number of shares of
Common Stock which are authorized by the Company's certificate of incorporation
and not outstanding or subscribed for, or reserved or otherwise committed for
issuance for purposes other than upon exercise of the Rights, are not sufficient
to permit the holder of each Right to purchase the number of shares of Common
Stock to which he would be entitled upon the exercise in full of the Rights in
accordance with the foregoing subparagraph (ii) of paragraph (a) of this Section
11, or should the Board of Directors so elect, the Company shall: (A) determine
the excess of (1) the value of the Common Stock issuable upon the exercise of a
Right (calculated as provided in the last sentence of this subparagraph (iii))
pursuant to Section 11(a)(ii) hereof (the "Current Value") over (2) the Purchase
Price (such excess, the "Spread"), and (B) with respect to each Right, make
adequate provision to substitute for such Common Stock, upon payment of the
applicable Purchase Price, any one or more of the following having an aggregate
value determined by the Board of Directors to be equal to the Current Value: (1)
cash, (2) a reduction in the Purchase Price, (3) Common Stock or other equity
securities of the Company (including, without limitation, shares, or units of
shares, of preferred stock which the Board of Directors of the Company has
determined to have the same value as shares of Common Stock (such shares of
preferred stock, "common stock equivalents")), (4) debt securities of the
Company, (5) other assets ,any combination of the foregoing, having an aggregate
value equal to the Current Value, where such aggregate value has been determined
by the Board of Directors of the Company, based upon the advice of a nationally
recognized investment banking firm selected by the Board of Directors of the
Company; provided, however, if the Company shall not have made adequate
provision to deliver value pursuant to clause (B) above within thirty (30) days
following the first occurrence of an event triggering the rights to purchase
Common Stock described in Section 11(a)(ii) (the "Section 11(a)(ii) Trigger
Date"), then the Company shall be obligated to deliver, upon the surrender for
exercise of a Right and without requiring payment of the Purchase Price, shares
of Common Stock (to the extent available) and then, if necessary, cash, which
shares and cash have an aggregate value equal to the Spread. If the Board of
Directors of the Company 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, 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
period, as it may be extended, the "Substitution Period"). To the extent that
the Company determines that some action need be taken pursuant to the first
and/or second sentences of this Section 11(a)(iii), the Company (x) shall
provide, subject to the last paragraph of Section 11(a)(ii) hereof, that such
action shall apply uniformly to all outstanding Rights, and (y) may suspend the
exercisability of the Rights until the expiration of


                                       12
<PAGE>   16
the Substitution Period in order to seek any authorization of additional shares
and/or to decide the appropriate form of distribution to be made pursuant to
such first sentence and to determine the value thereof. In the event of any such
suspension, the Company shall make a public announcement, and shall deliver to
the Rights Agent a statement, stating that the exercisability of the Rights has
been temporarily suspended. At such time as the suspension is no longer in
effect, the Company shall make another public announcement, and deliver to the
Rights Agent a statement, so stating. For purposes of this Section 11(a)(iii),
the value of the Common Stock shall be the current per share market price (as
determined pursuant to Section 11(d)(i) hereof) of the Common Stock on the
Section 11(a)(ii) Trigger Date and the value of any common stock equivalent
shall be deemed to have the same value as the Common Stock on such date.

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

                  (c) In case the Company shall fix a record date for the making
of a distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those


                                       13
<PAGE>   17
referred to in Section 11(b) hereof), the Purchase Price to be in effect after
such record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the then current per share market price of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the denominator of which shall be such
current per share market price of the Preferred Shares; provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
to be issued upon exercise of one Right. Such adjustments shall be made
successively whenever such a record date is fixed; and in the event that such
distribution is not so made, the Purchase Price shall again be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.

                  (d)      (i) For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11(d)(i)) on any date shall be deemed to be the average of the
daily closing 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 in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the Nasdaq National Market System
("NASDAQ"), if the Security is not listed or admitted to trading on the NASDAQ,
as reported in the principal consolidated transaction reporting system with
respect to securities listed on the principal 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.



                                       14
<PAGE>   18
                           (ii) For the purpose of any computation hereunder,
the "current per share market price" of the Preferred Shares shall be determined
in accordance with the method set forth in Section 11(d)(i). If the Preferred
Shares are not publicly traded, the "current per share market price" of the
Preferred Shares shall be conclusively deemed to be the current per share market
price of the Common Stock as determined pursuant to Section 11(d)(i)
(appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof), multiplied by 1,000. If neither
the shares of Common Stock nor the Preferred Shares are publicly held or so
listed or traded, "current per share market price" shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent.

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

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

                  (g) All Rights originally issued by the Company subsequent to
any adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-thousandths of a
Preferred Share 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 (c), each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-thousandths of a Preferred Share (calculated to the nearest one
ten-millionth of a Preferred Share) obtained by (i) multiplying (x) the number
of one one-thousandths of a share covered by a Right immediately prior to this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.



                                       15
<PAGE>   19
                  (i) The Company may elect on or after the date of any
adjustment of the Purchase Price to adjust the number of Rights in substitution
for any adjustment in the number of one one-thousandths of a Preferred Share
purchasable upon the exercise of a Right. Each of the Rights outstanding after
such adjustment of the number of Rights shall be exercisable for the number of
one one-thousandths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one hundred-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to adjustment of the Purchase Price
by the Purchase Price in effect immediately after adjustment of the Purchase
Price. The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made. This record date may
be the date on which the Purchase Price is adjusted or any day thereafter, but,
if the Right Certificates have been distributed, shall be at least 10 days later
than the date of the public announcement. If Right Certificates have been
distributed, upon each adjustment of the number of Rights pursuant to this
Section 11(i), the Company shall, as promptly as practicable, cause to be
distributed to holders of record of Right Certificates on such record date Right
Certificates evidencing, subject to Section 14 hereof, the additional Rights to
which such holders shall be entitled as a result of such adjustment, or, at the
option of the Company, shall cause to be distributed to such holders of record
in substitution and replacement for the Right Certificates held by such holders
prior to the date 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 to be so 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-thousandths of a Preferred Share issuable upon
the exercise of the Rights, the Right Certificates theretofore and thereafter
issued may continue to express the Purchase Price and the number of one
one-thousandths of a Preferred Share which were expressed in the initial Right
Certificates issued hereunder.

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

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


                                       16
<PAGE>   20
deliver to such holder a due bill or other appropriate instrument evidencing
such holder's right to receive such additional shares upon the occurrence of the
event requiring such adjustment.

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

                  (n) In the event that at any time after the date of this
Agreement and prior to the Distribution Date, the Company shall (i) declare or
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 other than by payment of dividends in shares of
Common Stock) into a greater or lesser number of shares of Common Stock, then in
any such case (i) the number of one one-thousandths of a Preferred Share
purchasable after such event upon proper exercise of each Right shall be
determined by multiplying the number of one one-thousandths of a Preferred Share
so purchasable immediately prior to such event by a fraction, the numerator of
which is the number of shares of Common Stock outstanding immediately before
such event and the denominator of which is the number of shares of Common Stock
outstanding immediately after such event, and (ii) each share of Common Stock
outstanding immediately after such event shall have issued with respect to it
that number of Rights which each share of Common Stock outstanding immediately
prior to such event had issued with respect to it. The adjustments provided for
in this Section 11(n) shall be made successively whenever such a dividend is
declared or paid or such a subdivision, combination or consolidation is
effected.

         Section 12. Certificate of Adjustment. Whenever an adjustment is made
as provided in Sections 11 and 13 hereof, the Company shall promptly (a) prepare
a certificate setting forth such adjustment, and a brief statement of the facts
accounting for such adjustment, (b) file with the Rights Agent and with each
transfer agent for the Common Stock or the Preferred Shares a copy of such
certificate and (c) mail a brief summary thereof to each holder of a Right
Certificate in accordance with Section 25 hereof. Notwithstanding the foregoing
sentence, the failure by the Company to make such certification or give such
notice shall not affect the validity of or the force or effect of the
requirement for such adjustment. The Rights Agent shall be fully protected in
relying on any such certificate and on any adjustment therein contained.


         Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earning Power. In the event that, at any time after a Person becomes an
Acquiring Person, directly or indirectly, (i) the Company shall consolidate
with, or merge with and into, any other Person, (ii) any Person shall
consolidate with the Company, or merge with and into the Company and the Company
shall


                                       17
<PAGE>   21
be the continuing or surviving corporation of such merger and, in connection
with such merger, all or part of the shares of Common Stock shall be changed
into or exchanged for stock or other securities of any other Person (or the
Company) or cash or any other property, or (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 of
its wholly-owned Subsidiaries, then, and in each such case, proper provision
shall be made so that (A) each holder of a Right (except as otherwise provided
herein) shall thereafter have the right to receive, upon the exercise thereof at
a price equal to the then current Purchase Price multiplied by the number of one
one-thousandths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of shares of Common Stock of such other Person (including the
Company as successor thereto or as the surviving corporation) as shall equal the
result obtained by (x) multiplying the then current Purchase Price by the number
of one one-thousandths of a Preferred Share for which a Right is then
exercisable and dividing that product by (y) 50% of the then current per share
market price of the Common Stock of such other Person (determined pursuant to
Section 11(d) hereof) on the date of consummation of such consolidation, merger,
sale or transfer; (B) the issuer of such Common Stock shall thereafter be liable
for, and shall assume, by virtue of such consolidation, merger, sale or
transfer, all the obligations and duties of the Company pursuant to this
Agreement; (C) the term "Company" shall thereafter be deemed to refer to such
issuer; and (D) such issuer 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 as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to the Common Stock thereafter
deliverable upon the exercise of the Rights. The Company covenants and agrees
that it shall not consummate any such consolidation, merger, sale or transfer
unless prior thereto the Company and such issuer shall have executed and
delivered to the Rights Agent a supplemental agreement so providing. The Company
shall not enter into any transaction of the kind referred to in this Section 13
if at the time of such transaction there are any rights, warrants, instruments
or securities outstanding or any agreements or arrangements which, as a result
of the consummation of such transaction, would eliminate or substantially
diminish the benefits intended to be afforded by the Rights. The provisions of
this Section 13 shall similarly apply to successive mergers or consolidations or
sales or other transfers. For purposes hereof, the "earning power" of the
Company and its Subsidiaries shall be determined in good faith by the Company's
Board of Directors on the basis of the operating earnings of each business
operated by the Company and its Subsidiaries during the three fiscal years
preceding the date of such determination (or, in the case of any business not
operated by the Company or any Subsidiary during three full fiscal years
preceding such date, during the period such business was operated by the Company
or any Subsidiary).

         Section 14. Fractional Rights and Fractional Shares.

                  (a) The Company shall not be required to issue fractions of
Rights or to distribute Right Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Right Certificates with regard to which such


                                       18
<PAGE>   22
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right. For the purposes of
this Section 14(a), the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such fractional Rights would have been otherwise issuable. The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the Rights are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Rights are listed or
admitted to trading or, if the Rights are not listed or admitted to trading on
any national securities exchange, the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported by NASDAQ or such other system then in use or, if on any such date
the Rights are not quoted by any such organization, the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Rights selected by the Board of Directors of the Company. If on any such
date no such market maker is making a market in the Rights, the fair value of
the Rights on such date as determined in good faith by the Board of Directors of
the Company shall be used.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions which are integral multiples of one one-thousandth of a Preferred
Share). Fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, be
evidenced by depository receipts, pursuant to an appropriate agreement between
the Company and a depository selected by it; provided, that such agreement shall
provide that the holders of such depository receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depository receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth of a Preferred Share, the Company shall pay to each registered
holder of Right Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of one Preferred Share as the fraction of one Preferred Share that such
holder would otherwise receive upon the exercise of the aggregate number of
rights exercised by such holder. For the purposes of this Section 14(b), the
current market value of a Preferred Share shall be the closing price of a
Preferred Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

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

         Section 15. Rights of Action. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the


                                       19
<PAGE>   23
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) may, 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, enforce, and may
institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act in respect of, his right to exercise the Rights
evidenced by such Right Certificate in the manner provided in such Right
Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and will be entitled to specific performance of the
obligations under, and injunctive relief against actual or threatened violations
of the obligations of any Person subject to, this Agreement.

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

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

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

                  (c) the Company and the Rights Agent may deem and treat the
person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common 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 associated 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 Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

<PAGE>   24
         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 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 or
liability in connection therewith.

                  (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 Preferred Shares or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement, or other
paper or document believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged, by the proper Person or Persons.

         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 corporate trust business of the Rights Agent or any successor
Rights Agent, shall be the successor to the Rights Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, provided that such corporation would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
hereof. In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement, any of the Right Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such Right
Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

                  (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.



                                       21
<PAGE>   25
         Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations expressly set forth in this Agreement and no implied
duties or obligations shall be read into this Agreement against the Rights
Agent. The Rights Agent shall perform those duties and obligations upon the
following terms and conditions, by all of which the Company and the holders of
Right Certificates, by their acceptance thereof, shall be bound:

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

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

                  (c) The Rights Agent shall be liable hereunder only for its
own negligence, bad faith or willful misconduct.

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

                  (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 adjustment required under the provisions of
Sections 11 or 13 hereof or responsible for the manner, method or amount of any
such adjustment or the ascertaining of the existence of facts that would require
any such adjustment (except with respect to the exercise of Rights evidenced by
Right Certificates after actual notice of any such adjustment); nor shall it by
any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any shares of Preferred Shares to be issued
pursuant to this Agreement or any Right Certificate or as to whether any
Preferred Shares will, when so issued, be validly authorized and issued, fully
paid and nonassessable.



                                       22
<PAGE>   26
                  (f) The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.

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

                  (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not 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.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Stock and the Preferred Shares by registered or certified mail,
and to the holders of the Right Certificates by first-class mail. The Company
may remove the Rights Agent or any successor Rights Agent upon 30 days' notice
in writing, mailed to the Rights Agent or successor Rights Agent, as the case
may be, and to each transfer agent of the Common Stock and the Preferred Shares
by registered or certified mail, and to the holders of the Right Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (who shall,
with such notice, submit his Right Certificate for inspection by the Company),
then the registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be a
corporation organized and doing business under the laws of the United States or
of any state of the United States, in good standing, having an office in the
State of California which is authorized under such laws to exercise corporate
trust powers and is subject to supervision or


                                       23
<PAGE>   27
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 $100
million. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Stock
and the Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Right Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Right Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of shares of Common Stock following the Distribution
Date and prior to the Final Expiration Date, the Company (a) shall, with respect
to shares of Common Stock so issued or sold pursuant to the exercise of stock
options or under any employee benefit plan or arrangement or upon the exercise,
conversion or exchange of securities of the Company currently outstanding or
issued at any time in the future by the Company and (b) may, in any other case,
if deemed necessary or appropriate by the Board of Directors of the Company,
issue Rights Certificate representing the appropriate number of Rights in
connection with such issuance or sale; provided, however, that (i) no such
Rights Certificate shall be issued and this sentence shall be null and void ab
initio if, and to the extent that, such issuance or this sentence would create a
significant risk of or result in material adverse tax consequences to the
Company or the Person to whom such Rights Certificate would be issued or would
create a significant risk of or result in such options' or employee plans' or
arrangements' failing to qualify for otherwise available special tax treatment
and (ii) no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

         Section 23. Redemption

                  (a) The Board of Directors of the Company may, at its option,
at any time prior to the earlier of (i) the Close of Business on the tenth
calendar date following the Shares Acquisition Date, or (ii) the Final
Expiration Date, redeem all but not less than all of the then outstanding Rights
at a redemption price of $0.01 per Right, appropriately adjusted to reflect any
stock split, stock dividend or similar transaction occurring after the date
hereof (such redemption price being hereinafter referred to as the "Redemption
Price"). The redemption of the Rights by the Board of Directors may be made
effective at such time, on such basis and subject to such conditions as the
Board of Directors in its sole discretion may establish.


                                       24
<PAGE>   28
                  (b) Immediately upon the time of the effectiveness of the
redemption of the Rights pursuant to paragraph (a) of this Section 23 or such
earlier time as may be determined by the Board of Directors of the Company in
the action ordering such redemption (although not earlier than the time of such
action) (such time the "Redemption Date"), and without any further action and
without any notice, the right to exercise the Rights shall terminate and the
only right thereafter of the holders of Rights shall be to receive the
Redemption Price. The Company shall promptly give public notice of any such
redemption; provided, however, that the failure to give, or any defect in, any
such notice shall not affect the validity of such redemption. Within 10 days
after such action of the Board of Directors ordering the redemption of the
Rights pursuant to paragraph (a), 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. If the payment of the
Redemption Price is not included with such notice, each such notice shall state
the method by which the payment of the Redemption Price will be made. Neither
the Company nor any of its Affiliates or Associates may redeem, acquire or
purchase for value any Rights at any time in any manner other than that
specifically set forth in this Section 23 or in Section 24 hereof, other than in
connection with the purchase of Common Stock prior to the Distribution Date.

         Section 24. Exchange.

                  (a) The Board of Directors of the Company may, at its option,
at any time after any Person becomes an Acquiring Person, exchange all or part
of the then outstanding and exercisable Rights (which shall not include Rights
that have become void pursuant to the provisions of Section 11(a)(ii) hereof)
for shares of Common Stock at an exchange ratio of one share of Common Stock per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any such Subsidiary, or any entity
holding Common Stock for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of a majority of the Common Stock then outstanding.

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the exchange of any Rights pursuant to subsection (a) of
this Section 24 and without any further action and without any notice, the right
to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of 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 promptly
shall mail a notice of any such exchange to all of the holders of such Rights at
their last addresses as they appear upon the registry books of


                                       25
<PAGE>   29
the Rights Agent. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of exchange will state the method by which the exchange of the Common 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.

                  (c) In any exchange pursuant to this Section 24, the Company,
at its option, may substitute Preferred Shares or common stock equivalents for
shares of Common Stock exchangeable for Rights, at the initial rate of one
one-thousandth of a Preferred Share (or an appropriate number of common stock
equivalents) for each share of Common Stock, as appropriately adjusted to
reflect adjustments in the voting rights of the Preferred Shares pursuant to the
terms thereof, so that the fraction of a Preferred Share delivered in lieu of
each share of Common Stock shall have the same voting rights as one share of
Common Stock.

                  (d) In the event that there shall not be sufficient shares of
Common Stock, Preferred Shares or common stock equivalents authorized by the
Company's certificate of incorporation and not outstanding or subscribed for, or
reserved or otherwise committed for issuance for purposes other than upon
exercise of Rights, to permit any exchange of Rights as contemplated in
accordance with this Section 24, the Company shall take all such action as may
be necessary to authorize additional Common Stock, Preferred Shares or common
stock equivalents for issuance upon exchange of the Rights.

                  (e) The Company shall not be required to issue fractions of
Common Stock or to distribute certificates which evidence fractional shares of
Common Stock. 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 per share market value
of a whole share of Common Stock. For the purposes of this paragraph (e), the
current per share market value of a whole share of Common Stock shall be the
closing price of a share of Common Stock (as determined pursuant to the second
sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to
the date of exchange pursuant to this Section 24.

         Section 25. Notice of Certain Events.

                  (a) In case the Company shall after the Distribution Date
propose (i) to pay any dividend payable in stock of any class to the holders of
its Preferred Shares or to make any other distribution to the holders of its
Preferred Shares (other than a regular quarterly cash dividend), (ii) to offer
to the holders of its Preferred Shares rights or warrants to subscribe for or to
purchase any additional Preferred Shares or shares of stock of any class or any
other securities, rights or options, (iii) to effect any reclassification of its
Preferred Shares (other than a reclassification involving only the subdivision
of outstanding Preferred Shares), (iv) to effect any consolidation or merger
into or with, or to effect any sale or other transfer (or to permit one or more
of its Subsidiaries to effect any sale or other transfer), in one or more
transactions, of 50%


                                       26
<PAGE>   30
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to, any other Person, (v) to effect the liquidation,
dissolution or winding up of the Company, or (vi) to declare or pay any dividend
on the Common Stock payable in shares of Common Stock or to effect a
subdivision, combination or consolidation of the Common Stock (by
reclassification or otherwise than by payment of dividends in shares of 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
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution, or winding up is to take place and the date of participation
therein by the holders of the Common Stock and/or Preferred Shares, if any such
date is to be fixed, and such notice shall be so given in the case of any action
covered by clause (i) or (ii) above at least 10 days prior to the record date
for determining holders of the Preferred Shares for purposes of such action, and
in the case of any such other action, at least 10 days prior to the date of the
taking of such proposed action or the date of participation therein by the
holders of the Common Stock and/or Preferred Shares, whichever shall be the
earlier.

                  (b) In case any event set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate, in accordance with 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)
hereof.

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

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



         NETsilicon, Inc., a corporation organized and existing under the
Business Corporation Law of the Commonwealth of Massachusetts (hereinafter
called the "Corporation"), hereby certifies that the following resolution was
adopted by the Board of Directors of the Corporation as required by Section 59
of Chapter 156B of the Business Corporation Law at a meeting duly called and
held on September 12, 2000:

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

         Section 1. Designation and Amount. The shares of this series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be one hundred thousand (100,000). Such number of shares may be
increased or decreased by resolution of the Board of Directors; provided, that
no decrease shall reduce the number of shares of Series A Preferred Stock to a
number less than the number of shares then outstanding plus the number of shares
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Corporation convertible into Series A Preferred Stock.

         Section 2. Dividends and Distributions.

                  (a) Subject to the rights of the holders of any shares of any
series of Preferred Stock (or any other stock) ranking prior and superior to the
Series A Preferred Stock with respect


                                      A-1
<PAGE>   35
to dividends, the holders of shares of Series A Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for the purpose, quarterly dividends payable in cash on
the last day of March, June, September and December in each year (each such date
being referred to herein as a "Quarterly Dividend Payment Date"), commencing on
the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Stock, in an amount (if any) per share
(rounded to the nearest cent), subject to the provision for adjustment
hereinafter set forth, equal to 1,000 times the aggregate per share amount of
all cash dividends, and 1,000 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, par value $.01 per share (the "Common
Stock"), of the Corporation or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

                  (b) The Corporation shall declare a dividend or distribution
on the Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock).

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



                                      A-2
<PAGE>   36
         Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                  (a) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 1,000 votes on all matters submitted to a vote of the stockholders of the
Corporation. In the event the Corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the number of votes per share to which holders of shares of
Series A Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

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

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

         Section 4. Certain Restrictions.

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

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

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



                                      A-3
<PAGE>   37
                  (iii) redeem or purchase or otherwise acquire for
consideration shares of any stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock,
provided that the Corporation may at any time redeem, purchase or otherwise
acquire shares of any such junior stock in exchange for shares of any stock of
the Corporation ranking junior (as to dividends and upon dissolution,
liquidation or winding up) to the Series A Preferred Stock.

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

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

         Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation the holders of shares
of Series A Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
1,000 times the aggregate amount to be distributed per share to holders of
shares of Common Stock plus an amount equal to any accrued and unpaid dividends.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the preceding sentence
shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

         Section 7. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1,000 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by


                                      A-4
<PAGE>   38
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 8. Amendment. The Restated Articles of Organization, as
amended, shall not be amended in any manner, including in a merger or
consolidation, which would alter, change, or repeal the powers, preferences or
special rights of the Series A Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of at least two-thirds of the
outstanding shares of Series A Preferred Stock, voting together as a single
class.

         Section 9. Rank. The Series A Preferred Stock shall rank, with respect
to the payment of dividends and upon liquidation, dissolution and winding up,
junior to all series of Preferred Stock.

adjustment upon the happening of certain events.

         From and after the occurrence of an event described in Section

such event and (y) the Distribution Date (as such term is defined in the Rights
Agreement) acquired or beneficially owned by an Acquiring Person or an Associate
or Affiliate of an Acquiring Person (as such terms are defined in the Rights
Agreement), such Rights shall become void, and any holder of such Rights shall
thereafter have no right to exercise such Rights.

                                                                       EXHIBIT C


                                NETSILICON, INC.
                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

         On September 12, 2000, the Board of Directors of NETsilicon, Inc.
declared a dividend of one preferred share purchase right (a "Right") for each
outstanding share of common stock, par value $.01 per share (the "Common Stock")
outstanding on September 23, 2000 (the "Record Date") to the stockholders of
record on that date. Each Right entitles the registered holder to purchase from
the Company one one-thousandth of a share of Series A Junior Participating
Preferred Stock, par value $0.01 per share (the "Preferred Shares"), of the
Company, at a price of $200.00 per one one-thousandth of a Preferred Share (the
"Purchase Price"), subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") between the
Company and Rights Agents (the "Rights Agent").

         Until the earlier to occur of (i) the tenth calendar day after a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired beneficial ownership of 15% or, in the case of
Osicom Technologies, Inc. (the "Grandfathered Stockholder"), an additional 1%,
or more of the outstanding voting securities of the Company 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 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, in the case of the Grandfathered
Stockholder, an additional 1%, or more of such outstanding voting securities of
the Company (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
with a copy of this Summary of Rights attached thereto.

         The Rights Agreement provides that, until the Distribution Date, the
Rights will be transferred with and only with the Common Stock. Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Stock certificates issued after the Record Date or upon transfer or new
issuance of Common Stock will contain a notation incorporating the Rights
Agreement by reference. Until the Distribution Date (or earlier redemption or
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 being attached thereto, will also
constitute the transfer of the Rights associated with the 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


                                      C-1
<PAGE>   46
September 12, 2010 (the "Final Expiration Date"), unless the Final Expiration
Date is extended or unless the Rights are earlier redeemed by the Company, in
each case, as described below.

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

         The number of outstanding Rights and the number of one one-thousandths
of a Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Stock or a stock dividend
on the Common Stock payable in shares of Common Stock or subdivisions,
consolidations or combinations occurring, in any such case, prior to the
Distribution Date.

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

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

         From and after the occurrence of an event described in Section
11(a)(ii) of the Rights Agreement, if the Rights evidenced by this Right
Certificate are or were at any time on or after the earlier of (x) the date of
such event and (y) the Distribution Date (as such term is defined in the Rights
Agreement) acquired or beneficially owned by an Acquiring Person or an Associate
or Affiliate of an Acquiring Person (as such terms are defined in the Rights
Agreement), such Rights shall become void, and any holder of such Rights shall
thereafter have no right to exercise such Rights.

         In the event that, at any time after a Person becomes 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 provision will be made so that each holder


                                      C-2
<PAGE>   47
of a Right will thereafter have the right to receive, upon the exercise thereof
at the then current exercise price of the Right, that number of shares of common
stock of the acquiring company which at the time of such transaction will have a
market value of two times the exercise price of the Right. In the event that any
person becomes an Acquiring Person, proper provision shall be made so that each
holder of a Right, other than Rights beneficially owned by the Acquiring Person
and its Affiliates and Associates (which will thereafter be void), will
thereafter have the right to receive upon exercise that number of shares of
Common Stock having a market value of two times the exercise price of the Right.
If the Company does not have sufficient shares of Common Stock to satisfy such
obligation to issue Common Stock, or if the Board of Directors so elects, the
Company shall deliver upon payment of the exercise price of a Right an amount of
cash or securities equivalent in value to the Common Stock issuable upon
exercise of a Right; provided that, if the Company fails to meet such obligation
within 30 days following the later of (x) the first occurrence of an event
triggering the right to purchase Common Stock and (y) the date on which the
Company's right to redeem the Rights expires, the Company must deliver, upon
exercise of a Right but without requiring payment of the exercise price then in
effect, Common Stock (to the extent available) and cash equal in value to the
difference between the value of the Common Stock otherwise issuable upon the
exercise of a Right and the exercise price then in effect. The Board of
Directors may extend the 30-day period described above for up to an additional
90 days to permit the taking of action that may be necessary to authorize
sufficient additional shares of Common Stock to permit the issuance of Common
Stock upon the exercise in full of the Rights.

         At any time after any Person becomes an Acquiring Person and prior to
the acquisition by any person or group of a majority of the outstanding Common
Stock, the Board of Directors of the Company may exchange the Rights (other than
Rights owned by such person or group which have become void), in whole or in
part, at an exchange ratio of one share of Common Stock per Right (subject to
adjustment).

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

         At any time prior to the tenth day following the time any Person
becomes an Acquiring Person, the Board of Directors of the Company may redeem
the Rights in whole, but not in part, at a price of $0.01 per Right (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. 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.

         The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, except that from and
after such time as any


                                      C-3
<PAGE>   48
person becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights (other than the Acquiring Person and its
Affiliates and Associates).

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

         A copy of the Agreement has been filed with the Securities and Exchange
Commission as an Exhibit to a Registration Statement on Form 8-A dated September
13, 2000 . A copy of the 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 Agreement, which is hereby
incorporated herein by reference.
