ITEM 5.  OTHER EVENTS.

         Adoption of Rights Agreement.

         On July 24, 1998, the Board of Directors (the "Board") of Trident
Microsystems (the "Company") declared a dividend distribution of one Preferred
Stock Purchase Right (each a "Right" and collectively the "Rights") for each
outstanding share of Common Stock, $0.001 par value ("Common Stock"), of the
Company. The distribution was paid as of August 14, 1998 (the "Record Date"), to
stockholders of record on that date. Each Right entitles the registered holder
to purchase from the Company one one-hundredth of a share of the Company's
Series A Preferred Stock, $0.001 par value ("Preferred Stock"), at a price of
$50.00 (the "Purchase Price"). The description and terms of the Rights are set
forth in the Rights Agreement dated as of July 24, 1998 (the "Rights
Agreement"), between the Company and ChaseMellon Shareholder Services, L.L.C.
(the "Rights Agent").

         Until the earlier to occur of (i) the tenth day following the first
date of public announcement by the Company or by a person or group of affiliated
or associated persons ("Acquiring Person") other than (x) the Company or any
subsidiary of the Company or any employee benefit plan or employee stock plan of
the Company including, without limitation, in its fiduciary capacity, any
subsidiary of the Company or any individual, firm, corporation, partnership,
trust or other entity (a "Person") organized, appointed, established or holding
Common Stock for or pursuant to the terms of any such plan or any Person funding
other employee benefits for employees of the Company or any subsidiary of the
Company or (y) Frank C. Lin so long as he remains the Chief Executive Officer of
the Company and does not, together with his affiliates and associates other than
the Company and its subsidiaries, own more than twenty-five percent (25%) of the
outstanding shares of Common Stock ("Exempt Person"), that such Acquiring Person
has acquired, or obtained the right to acquire, without approval of the Board or
good faith determination of the Board that such person or group of affiliated or
associated persons has inadvertently become an Acquiring Person, beneficial
ownership of securities of the Company representing 15% or more of the
outstanding Common Stock (other than solely as a result of a reduction in the
outstanding shares of Common Stock or such earlier date as a majority of the
Board shall become aware of such acquisition of the Common Stock (the "Stock
Acquisition Date") (or, if the tenth day after the Stock Acquisition Date occurs
before the Record Date, the close of business on the Record Date) or (ii) the
tenth business day (subject to extension by the Board prior to the time a Person
becomes an Acquiring Person) following the commencement of, or public
announcement of an intention to commence, a tender or exchange offer by any
Person (other than by an Exempt Person), the consummation of which would result
in the beneficial ownership of 15% or more of the outstanding Common Stock by
such Person, together with its affiliates and associates (the earlier of such
dates being called the "Distribution Date"), the Rights will be evidenced, with
respect to all shares of Common Stock that are issued after the Record Date
prior to the Distribution Date (or earlier redemption or expiration of the
Rights), by certificates representing such shares of Common Stock together with
the Summary of Rights attached thereto. The Board of Directors may extend the
periods specified in subsections (i) and (ii) above by up to three (3)
consecutive periods of ten (10) days each.

         The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights), the Rights will be represented
by and transferred with, and only with, Common Stock. Until the Distribution
Date (or earlier redemption or expiration of the Rights), new certificates
issued for Common Stock (including, without limitation, certificates issued upon
transfer or exchange of Common Stock) after the Record Date, will contain a
legend incorporating the Rights Agreement by reference. Until the Distribution
Date (or earlier redemption or expiration of the Rights), the surrender for
transfer of any of Common Stock certificates, with or without the aforesaid
legend or the Summary of Rights attached thereto, also will 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 Common Stock as of the close of business on the
Distribution Date, and such separate certificates alone will evidence the Rights
from and after the Distribution Date.

         The Rights are not exercisable until the Distribution Date. The Rights
will expire upon the earlier of (i) July 23, 2008 or (ii) redemption or exchange
by the Company.

         The number of shares of Preferred Stock or other securities or property
issuable, and the purchase price payable upon exercise of the Rights (the
"Purchase Price") 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 Stock, (ii) upon the grant to holders of
Preferred Stock of certain rights or warrants to subscribe for Preferred Stock
or convertible securities at less than the current market price of Preferred
Stock or (iii) upon the distribution to holders of the Preferred Stock of
evidences of indebtedness, cash or assets (excluding dividends payable in
Preferred Stock) or subscription rights or warrants (other than those referred
to above). The number of Rights associated with each share of Common Stock also
is subject to adjustment in the event of a stock split of the Common Stock or a
stock dividend on the Common Stock payable in Common Stock or subdivisions,
consolidations or combinations of the Common Stock occurring, in any such case,
prior to the Distribution Date.

         The Preferred Stock purchasable upon exercise of the Rights will be
nonredeemable and junior to any other series of preferred stock the Company may
issue (unless otherwise provided in the terms of such other series). Each share
of Preferred Stock will have a preferential cumulative quarterly dividend in an
amount equal to the greater of (a) $125.00 or (b) 100 times the dividend
declared on each share of Common Stock (other than dividends payable in shares
of Common Stock). In the event of liquidation, the holders of Preferred Stock
will receive a preferred liquidation payment equal to the greater of (a)
$5,000.00 per share, plus accrued dividends to the date of distribution whether
or not earned or declared, or (b) an amount per share equal to 100 times the
aggregate payment to be distributed per share of Common Stock. Each share of
Preferred Stock shall entitle the holder thereof to 100 votes, voting together
with the holders of shares of Common Stock. In the event of any merger,
consolidation or other transaction in which shares of Common Stock are exchanged
for or changed into other securities, cash and/or other property, each share of
Preferred Stock will be entitled to receive 100 times the amount and type of
consideration received per share of Common Stock. The rights of the Preferred
Stock as to dividends, liquidation and voting, and in the event of mergers and
consolidations, are protected by customary anti-dilution provisions. Fractional
shares (in integral multiples of one one-hundredth) of Preferred Stock will be
issuable; however, the Company may elect to distribute depositary receipts in
lieu of such fractional shares. In lieu of fractional shares other than
fractions that are multiples of one one-hundredth of a share, an adjustment in
cash will be made based on the market price of the Preferred Stock on the last
trading date prior to the date of exercise. Because of the nature of the
Preferred Stock's dividend, liquidation and voting rights, the value of one
one-hundredth of a share of Preferred Stock purchasable upon exercise of each
Right should approximate the value of one share of Common Stock.

         In the event (i) any person becomes an Acquiring Person or (ii) any
Acquiring Person or any of its affiliates or associates, directly or indirectly,
(1) consolidates with or merges into the Company or any of its subsidiaries or
otherwise combines with the Company or any of its subsidiaries in a transaction
in which the Company or such subsidiary is the continuing or surviving
corporation of such merger or combination and Common Stock remains outstanding
and no shares thereof are changed into or exchanged for stock or other
securities of any other Person or of the Company or cash or any other property,
(2) transfers, in on one or more transactions, any assets or property to the
Company or any of its subsidiaries in exchange for capital stock of the Company
or any of its subsidiaries or for securities exercisable for or convertible into
capital stock of the Company or any of its subsidiaries or otherwise obtains
from the Company or any of its subsidiaries, with or without consideration, any
capital stock of the Company or any of its subsidiaries or securities
exercisable for or convertible into capital stock of the Company or any of its
subsidiaries (other than as part of a pro rata offer or distribution to all
holders of such stock), (3) sells, purchases, leases, exchanges, mortgages,
pledges, transfers or otherwise acquires (other than as a pro rata dividend) or
disposes, to, from or with, as the case may be, in one transaction or a series
of transactions, the Company or any of its subsidiaries, assets (including
securities) on terms and conditions less favorable to the Company or such
subsidiary than the Company or such subsidiary would be able to obtain in
arm's-length negotiation with an unaffiliated third party, (4) receives any
compensation from the Company or any of its subsidiaries for services other than
compensation for employment as a regular or part-time employee, or fees for
serving as a director at rates in accordance with the Company's (or its
subsidiary's) past practice, (5) receives the benefit, directly or indirectly
(except proportionately as a stockholder), of any loans, advances, guarantees,
pledges or other financial assistance or tax credit or tax advantage, or (6)
engages in any transaction with the Company (or any of its subsidiaries)
involving the sale, license, transfer or grant of any right in, or disclosure
of, any patents, copyrights, trade secrets, trademarks or know-how (or any other
intellectual or industrial property rights recognized under any country's
intellectual property rights laws) which the Company (including its
subsidiaries) owns or has the right to use on terms and conditions not approved
by the Board, or (iii) while there is an Acquiring 

                                       2

Person, there shall occur any reclassification of securities (including any
reverse stock split), any recapitalization of the Company, or any merger or
consolidation of the Company with any of its subsidiaries or any other
transaction or series of transactions involving the Company or any of its
subsidiaries (whether or not involving the Acquiring Person or any affiliate or
associate of such Acquiring Person) which has the effect, directly or
indirectly, of increasing by more than 1% the proportionate share of the
outstanding shares of any class of equity securities of the Company or any of
its subsidiaries, or securities exercisable for or convertible into equity
securities of the Company or any of its subsidiaries, which is directly or
indirectly beneficially owned by the Acquiring Person or any affiliate or
associate of such Acquiring Person (such events are collectively referred to
herein as the "Flip-In Events"), then, and in each such case, each holder of
record of a Right, other than the Acquiring Person, will thereafter have the
right to receive, upon payment of the then current Purchase Price, in lieu of
one one-hundredth of a share of Preferred Stock per outstanding Right, that
number of shares of Common Stock having a market value at the time of the
transaction equal to the Purchase Price (as adjusted to the Purchase Price in
effect immediately prior to the Flip-In Event multiplied by the number of one
one-hundredths of a share of Preferred Stock for which a Right was exercisable
immediately prior to such Flip-In Event) divided by one-half the average of the
daily closing prices per share of Common Stock for the thirty consecutive
trading days ("Current Market Price") on the date of such Flip-In Event.
Notwithstanding the foregoing, Rights held by the Acquiring Person or any
associate or affiliate thereof or certain transferees will be null and void and
no longer will be transferable.

         The Company may at its option substitute for a share of Common Stock
issuable upon the exercise of Rights in accordance with the preceding paragraph
such number or fractions of shares of Preferred Stock having an aggregate
current market value equal to the Current Market Price of a share of Common
Stock. In the event that insufficient shares of Common Stock are available to
permit the exercise in full of the Rights in accordance with the foregoing
paragraph, the Board shall, to the extent permitted by applicable law and any
material agreements then in effect to which the Company is a party, (A)
determine the excess (such excess, the "Spread") of (1) the value of the shares
of Common Stock issuable upon the exercise of a Right in accordance with the
preceding sentence (the "Current Value") over (2) the Purchase Price, and (B)
with respect to each Right (other than Rights which have become void pursuant to
the foregoing paragraph), make adequate provision to substitute for the shares
of Common Stock issuable in accordance with the preceding sentence upon exercise
of the Right and payment of the Purchase Price, (1) cash, (2) a reduction in
such Purchase Price, (3) shares of Preferred Stock or other equity securities of
the Company (including, without limitation, shares or fractions of shares of
preferred stock which, by virtue of having dividend, voting and liquidation
rights substantially comparable to those of the shares of Common Stock, are
deemed in good faith by the Board to have substantially the same value as the
shares of Common Stock, (4) debt securities of the Company, (5) other assets, or
(6) any combination of the foregoing, having a value which, when added to the
value of the shares of Common Stock actually issued upon exercise of such Right,
shall have an aggregate value equal to the Current Value (less the amount of any
reduction in such Purchase Price); provided, however, that if the Company shall
not make adequate provision to deliver value pursuant to clause (B) above within
thirty (30) days (extendible up to a total of ninety (90) days under certain
circumstances) following the Flip-In Event, then the Company shall be obligated
to deliver, to the extent permitted by applicable law and any material
agreements then in effect to which the Company is a party, upon the surrender
for exercise of a Right and without requiring payment of such Purchase Price,
shares of Common Stock (to the extent available), and then, if necessary, such
number or fractions of shares of Preferred Stock (to the extent available) and
then, if necessary, cash, which shares and/or cash have an aggregate value equal
to the Spread. Rights are not exercisable following the occurrence of the events
set forth in the foregoing paragraph until the expiration of the period during
which the Rights may be redeemed as described below.

         Unless the Rights are earlier redeemed, in the event that following the
first occurrence of a Flip-In Event, the Company were to be acquired in a merger
or other business combination in which any shares of Common Stock are exchanged
or converted for other securities or assets (other than a merger or other
business combination in which the voting power represented by the Company's
securities outstanding immediately prior thereto continues to represent all of
the voting power represented by the securities of the Company thereafter and the
holders of such securities have not changed as a result of such transaction), or
50% or more of the assets or earning power of the Company and its subsidiaries
(taken as a whole) were to be sold or transferred in one or a series of related
transactions (such transactions are collectively referred to herein as the
"Flip-Over Events"), the Rights Agreement provides that proper provision shall
be made so that each holder of record of a Right (other than an Acquiring
Person, or affiliates or associates thereof) will from and after such date have
the right to receive, upon payment of the then current Purchase Price, that
number of shares of common stock of the acquiring company 

                                       3


<PAGE>   5

having a market value at the time of such transaction equal to the Purchase
Price divided by one-half the Current Market Price of such common stock.

         No fractional shares of Common Stock will be issued upon exercise of
the Rights and, in lieu thereof, a payment in cash will be made to the holder of
such Rights equal to the same fraction of the current market value of a share of
Common Stock.

         At any time until the occurrence of a Flip-In Event, the Board may
redeem the Rights in whole, but not in part, at a price of $0.001 per Right.
Immediately upon the action of the Board authorizing 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 without any interest
thereon.

         At any time after the occurrence of a Flip-In Event and prior to the
earlier of a Flip-Over Event or such time as any Person (other than an Exempt
Person), together with all affiliates and associates of such Person, becomes the
Beneficial Owner of more than 50% of the Common Stock outstanding, the Board
may, at its option, exchange all or any portion of the outstanding Rights (other
than Rights held by any Acquiring Person which have become void) for shares of
Common Stock on a pro rata basis, at an exchange ratio of one share of Common
Stock or one one-hundredth of a share of Preferred Stock (or of a share of a
class or series of the Company's Preferred Stock having equivalent rights,
preferences and privileges) per Right. Immediately upon the ordering of such
exchange 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 shares of Common Stock or Common Stock Equivalents pursuant to the
exchange. In the event there are insufficient shares of Common Stock issued but
not outstanding or authorized but unissued to permit any exchange of Rights, the
Company shall take all actions necessary to authorize additional shares of
Common Stock for issuance upon exchange of the Rights.

         Until the Rights become nonredeemable the Company may, except with
respect to the redemption price of the Rights, amend the Rights Agreement in any
manner. After the Rights become nonredeemable, the Company may amend the Rights
Agreement to cure any ambiguity, to correct or supplement any provision which
may be defective or inconsistent with any other provisions, to shorten or
lengthen any time period under the Rights Agreement, or to arrange or supplement
the provisions hereunder in any manner which the Company may deem necessary or
desirable, provided that no such amendment may adversely affect the interests of
the holders of the Rights (other than the Acquiring Person or its affiliates or
associates) or cause the Rights to again be redeemable or the Agreement to again
be freely amendable.

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

         The issuance of the Rights is not taxable to the Company or to
stockholders under presently existing federal income tax law, and will not
change the way in which stockholders can presently trade shares of Common Stock.
If the Rights should become exercisable, stockholders, depending on then
existing circumstances, may recognize taxable income.

         The Rights have certain anti-takeover effects. Under certain
circumstances the Rights could cause substantial dilution to a person or group
who attempts to acquire the Company on terms not approved by the Board. However,
the Rights should not interfere with any merger or other business combination
approved by the Board.

         The form of Rights Agreement between the Company and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent (including as Exhibit A the form
of Certificate of Designation, Preferences and Rights of the Terms of the Series
A Preferred Stock, as Exhibit B the form of Right Certificate, and as Exhibit C

                                RIGHTS AGREEMENT


         This Rights Agreement ("Rights Agreement"), is dated as of July 24,
1998, between Trident Microsystems, Inc., a Delaware corporation (the
"Company"), and ChaseMellon Shareholder Services, LLC (the "Rights Agent").

                                   WITNESSETH:

         WHEREAS, the Board of Directors of the Company on July 24, 1998, (i)
authorized the issuance and declared a dividend of one right ("Right") for each
share of the common stock of the Company ("Common Stock") outstanding as of the
Close of Business (as such term is hereinafter defined) on August 14, 1998 (the
"Record Date"), each Right representing the right to purchase one one-hundredth
of a share of Series A Preferred Stock of the Company having the rights, powers
and preferences set forth in the form of Certificate of Designation attached
hereto as Exhibit A upon the terms and subject to the conditions hereinafter set
forth, and (ii) further authorized the issuance of one Right with respect to
each share of Common Stock of the Company that shall become outstanding between
August 14, 1998, and the Distribution Date (as such term is hereinafter
defined);

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

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

                  (a) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, without the prior approval of the Board of Directors, shall be the
Beneficial Owner (as such term is hereinafter defined) of fifteen percent (15%)
or more of the outstanding Common Stock; provided, however, that in no event
shall a Person who or which, together with all Affiliates and Associates of such
Person, is the Beneficial Owner of less than fifteen percent (15%) of the
Company's outstanding shares of Common Stock, become an Acquiring Person solely
as a result of a reduction of the number of shares of outstanding Common Stock,
including repurchases of outstanding shares of Common Stock by the Company,
which reduction increases the percentage of outstanding shares of Common Stock
beneficially owned by such Person, provided, however, that if a Person shall
become the Beneficial Owner of fifteen percent (15%) or more of the Company's
outstanding shares of Common Stock then outstanding solely by reason of a
reduction of the number of shares of outstanding Common Stock, and shall
thereafter become the Beneficial Owner of any additional shares of Common Stock
of the Company, then such Person shall be deemed to be an "Acquiring Person"
unless upon the consummation of the acquisition of such additional shares of
Common Stock such person does not own fifteen percent (15%) or more of the
shares of Common Stock then outstanding, and provided further, that an Acquiring
Person shall not include an Exempt Person (as such term is hereinafter defined).
Notwithstanding the foregoing, if the Board of Directors of the Company
determines in good faith that a Person who would 

<PAGE>   4


otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently (including,
without limitation, because (i) such Person was unaware that it beneficially
owned a percentage of Common Stock that would otherwise cause such Person to be
an "Acquiring Person" or (ii) such Person was aware of the extent of its
Beneficial Ownership but had no actual knowledge of the consequences of such
Beneficial Ownership under this Agreement) and without any intention of changing
or influencing control of the Company, and such Person divests as promptly as
practicable a sufficient number of shares of Common Stock so that such Person
would no longer be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), then such Person shall not be deemed to be or
to have become an "Acquiring Person" for any purposes of this Agreement.

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

                  (c) A Person shall be deemed the "Beneficial Owner" of any
securities

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

                           (ii) which such Person or any of such Person's
Affiliates or Associates, directly or indirectly, 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), whether or not in
writing, 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 the "Beneficial Owner" of, or to "beneficially
own," securities tendered pursuant to a tender or exchange offer made by 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 or
dispose of or has "beneficial ownership" of (as determined pursuant to Rule
13d-3 of the General Rules and Regulations under the Exchange Act, or any
comparable or successor rule), including pursuant to any agreement, arrangement
or understanding (whether or not in writing); provided, however, that a Person
shall not be deemed the "Beneficial Owner" of, or to "beneficially own", any
securities if the agreement, arrangement or understanding to vote such security
(1) arises solely from a revocable proxy or consent given in response to a
public proxy or consent solicitation made pursuant to, and in accordance with,
the applicable rules and regulations of the Exchange Act and (2) is not also
then reportable by such Person 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 with which such Person or any of such Person's
Affiliates or Associates has any agreement, arrangement or understanding
(whether or not in writing) for the purpose of acquiring, holding, voting except
as described in clause (B) of subparagraph (ii) of this 


                                       2


<PAGE>   5

Section 1(c) or disposing of any securities of the Company; provided, however,
that no Person who is an officer, director or employee of an Exempt Person shall
be deemed, solely by reason of such Person's status or authority as such, to be
the "Beneficial Owner" of, to have "Beneficial Ownership" of or to "beneficially
own" any securities that are "beneficially owned" (as defined in this Section
1(c)), including, without limitation, in a fiduciary capacity, by an Exempt
Person or by any other such officer, director or employee of an Exempt Person.

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

not a Business Day it shall mean 5:00 P.M., San Francisco time, on the next
succeeding Business Day.

Subsidiary of or is controlled by another Person, the Person which ultimately

any Person other than the Company which shall not be organized in corporate form
shall mean units of beneficial interest which shall represent the right to
participate in profits, losses, deductions and credits of such Person and which
shall be entitled to exercise the greatest voting power per unit of such Person.

<PAGE>   8

appoints one or more Co-Rights Agents, the respective duties of the Rights
Agents and any Co-Rights Agents shall be as the Company shall determine.

         3. Issuance of Right Certificates.

                  (a) Until the earlier of (i) the tenth day after the Stock
Acquisition Date (or, if the tenth day after the Stock Acquisition Date occurs
before the Record Date, the Close of Business on the Record Date) or (ii) the
tenth business day (or such later date as may be determined by action of the
Board of Directors prior to such time as any Person becomes an Acquiring Person)
after the date of the commencement by any Person (other than an Exempt Person)
of, or of the first public announcement of the intent of any Person (other than
an Exempt Person) to commence (which intention to commence remains in effect for
five business days after such announcement), a tender or exchange offer upon the
successful consummation of which such Person, together with its Affiliates and
Associates, would be the Beneficial Owner of 15% or more of the outstanding
Common Stock (irrespective of whether any shares are actually purchased pursuant
to any such offer) (including any such date which is after the date of this
Agreement and prior to the issuance of the Rights; the earlier of such dates
being herein referred to as the "Distribution Date"), (x) the Rights will be
evidenced (subject to the provisions of Section 3(c) hereof) by the certificates
for the Common Stock registered in the names of the holders of the Common Stock
and not by separate Right Certificates, and (y) each Right will be transferable
only in connection with the transfer of a share (subject to adjustment as
hereinafter provided) of Common Stock. The Board of Directors may extend the
periods specified in subsections (i) and (ii) above by up to three (3)
consecutive periods of ten (10) days each, so that the determination of the
Distribution Date is delayed by the number of days provided for in such
extension or extensions. As soon as practicable after the Distribution Date, the
Rights Agent will mail, by first-class, postage prepaid mail, to each record
holder of the Common Stock as of the Close of Business on the Distribution Date,
as shown by the records of the Company, to the address of such holder shown on
such records, a Right certificate in substantially the form of Exhibit B hereto
("Right Certificate") evidencing one Right for each share of Common Stock so
held. As of and after the Distribution Date the Rights will be evidenced solely
by such Right Certificates.

                  (b) On the Record Date, or as soon as practicable thereafter,
the Company will send a copy of a Summary of Rights to Purchase Preferred Stock,
substantially in the form attached hereto as Exhibit C ("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.

                  (c) Rights shall be issued in respect of all shares of Common
Stock that are issued (either as an original issuance or from the Company's
treasury) after the Record Date prior to the earlier of the Distribution Date or
the Expiration Date. With respect to certificates representing such shares of
Common Stock, the Rights will be evidenced by such certificates for Common Stock
registered in the names of the holders thereof together with the Summary of
Rights. Until the Distribution Date (or, if earlier, the Expiration Date), the
surrender for transfer of any certificate for Common Stock outstanding on the
Record Date (with or without a copy of 

                                       6


<PAGE>   9

the Summary of Rights attached thereto), shall also constitute the surrender for
transfer of the Rights associated with the Common Stock represented thereby.

                  (d) Certificates issued for Common Stock (including, without
limitation, certificates issued upon transfer or exchange of Common Stock) after
the Record Date but prior to the earlier of the Distribution Date or the
Expiration Date shall have impressed on, printed on, written on or otherwise
affixed to them the following legend:

         This certificate also evidences and entitles the holder hereof to
         certain Rights as set forth in the Rights Agreement between Trident
         Microsystems, Inc. and ChaseMellon Shareholder Services, L.L.C., as
         Rights Agent, dated as of July 24, 1998, as the same may be amended
         from time to time (the "Rights Agreement"), the terms of which are
         incorporated herein by reference and a copy of which is on file at the
         principal executive office of Trident Microsystems, 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. Trident Microsystems, Inc. will mail to the holder
         of this certificate a copy of the Rights Agreement without charge after
         receipt by it of a written request therefor. Under certain
         circumstances as provided in the Rights Agreement, Rights issued to,
         beneficially owned by or transferred to any person who is or becomes an
         Acquiring Person (as defined in the Rights Agreement) or an Associate
         or Affiliate (as defined in the Rights Agreement) thereof and certain
         transferees thereof will be null and void and will no longer be
         transferable.

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

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

         4. Form of Right Certificates.

                  (a) The Right Certificates (and the forms of election to
purchase shares and of assignment to be printed on the reverse thereof), when,
as and if issued, shall be substantially in the form set forth in Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Rights
Agreement, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Rights may from time to time be 


                                       7


<PAGE>   10

listed, or to conform to usage. Subject to the provisions of Sections 11, 13 and
22 hereof, the Right Certificates evidencing the Rights issued on the Record
Date whenever such certificates are issued, shall be dated as of the Record Date
and the Right Certificates evidencing Rights to holders of record of Common
Stock issued after the Record Date shall be dated as of the Record Date but
shall also be dated to reflect the date of issuance of such Right Certificate.
On their face, Right Certificates shall entitle the holders thereof to purchase,
for each Right, one one-hundredth of a share of Preferred Stock, or other
securities or property as provided herein, as the same may from time to time be
adjusted as provided herein, at the price per share of $50.00, as the same may
from time to time be adjusted as provided herein (the "Purchase Price").

                  (b) Notwithstanding any other provision of this Rights
Agreement, any Right Certificate that represents Rights that are or were at any
time on or after the earlier of the Stock Acquisition Date or the Distribution
Date beneficially owned by an Acquiring Person or any Affiliate or Associate
thereof (or any transferee of such Rights) shall have impressed on, printed on,
written on or otherwise affixed to it (if the Company or the Rights Agent has
knowledge that such Person is an Acquiring Person or an Associate or Affiliate
thereof or transferee of such Persons or a nominee of any of the foregoing) the
following legend:

         The beneficial owner of the Rights represented by this Right
         Certificate is an Acquiring Person or an Affiliate or Associate (as
         defined in the Rights Agreement) of an Acquiring Person or a subsequent
         holder of such Right Certificates beneficially owned by such Persons.
         Accordingly, this Right Certificate and the Rights represented hereby
         are null and void and will no longer be transferable as provided in the
         Rights Agreement.

The provisions of Section 11(a)(ii) and Section 24 of this Rights Agreement
shall be operative whether or not the foregoing legend is contained on any such
Right Certificates.

         5. Countersignature and Registration.

                  (a) The Right Certificates shall be executed on behalf of the
Company by its Chief Executive Officer, its President or any Vice President,
either manually or by facsimile signature, and have affixed thereto the
Company's seal or a facsimile thereof which shall be attested by the Secretary
or an Assistant Secretary of the Company, either manually or by facsimile
signature. The Right Certificates shall be countersigned, either manually or by
facsimile, by the Rights Agent and shall not be valid for any purpose unless so
countersigned. In case any officer of the Company who shall have signed any of
the Right Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent,
issued and delivered with the same force and effect as though the person who
signed such Right Certificates had not ceased to be such officer of the Company;
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 one of its offices designated for such purposes,
records for registration and transfer of the Right Certificates issued
hereunder. Such records 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, the date of each of the Right Certificates and
the certificate numbers for each of the Right Certificates.

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

                  (a) Subject to the provisions of Sections 7(e), 11(a)(ii) and
14 hereof, at any time after the Close of Business on the Distribution Date and
at or prior to the Close of Business on the Expiration Date, any Right
Certificate or 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 (i) transferred or (ii) split
up, combined or exchanged for another Right Certificate or Right Certificates,
entitling the registered holder to purchase a like number of shares of Preferred
Stock or other securities as the Right Certificate or Right Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer any Right Certificate shall surrender the Right Certificate
at the office of the Rights Agent designated for such purposes with the form of
assignment on the reverse side thereof duly endorsed (or enclose with such Right
Certificate a written instrument of transfer in form satisfactory to the Company
and the Rights Agent), duly executed by the registered holder thereof or his
attorney duly authorized in writing, and with such signature guaranteed by a
member of a securities approved medallion program. Any registered holder
desiring to split up, combine or exchange any Right Certificate shall make such
request in writing delivered to the Rights Agent, and shall surrender the Right
Certificate or Right Certificates to be split up, combined or exchanged at the
principal office of the Rights Agent. Thereupon the Rights Agent shall, subject
to Sections 4(b), 7(e), 11 and 14 hereof, countersign (by manual or facsimile
signature) and deliver to the person entitled thereto a Right Certificate or
Right Certificates, as the case may be, as so requested. The Company may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer, split up, combination or exchange of
Right Certificates.

                  (b) Subject to the provisions of Section 11(a)(ii) hereof,
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, if requested by the Company,
reimbursement to the Company of all reasonable expenses incidental thereto, and
upon surrender to the Rights Agent and cancellation of the Right Certificate if
mutilated, the Company will execute and deliver a new Right Certificate of like
tenor to the Rights Agent for delivery to the registered owner in lieu of the
Right Certificate so lost, stolen, destroyed or mutilated.

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

                  (a) Subject to Section 11(a)(ii) hereof, the Rights shall
become exercisable, and may be exercised to purchase Preferred Stock, except as
otherwise provided herein, in whole or in part at any time after the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase on the reverse side thereof duly executed (with such
signature duly guaranteed), to the Rights Agent at 235 Montgomery Street, 23rd
Floor, San Francisco, California, 94104, Attention: Manager, together with
payment of the Purchase Price with respect to each Right exercised, subject to
adjustment as hereinafter provided, at or prior to the Close of Business on the
earlier of (i) July 23, 2008 (the "Final Expiration Date"), (ii) the time at
which the Rights are redeemed as provided in Section 23 hereof (such date being
herein referred to as the "Redemption Date") or (iii) the time at which all such
Rights are exchanged as provided in Section 24 hereof (the earliest of (i), (ii)
and (iii) being herein referred to as the "Expiration Date").

                  (b) The Purchase Price and the number of shares of Preferred
Stock or other securities or consideration to be acquired upon exercise of a
Right shall be subject to adjustment from time to time as provided in Sections
11 and 13 hereof. The Purchase Price shall be payable in lawful money of the
United States of America, in accordance with Section 7(c) hereof.

                  (c) Except as provided in Section 11(a)(ii) hereof, upon
receipt of a Right Certificate with the form of election to purchase duly
executed, accompanied by payment of the Purchase Price (as such amount may be
reduced pursuant to Section 11(a)(iii) hereof) or so much thereof as is
necessary for the shares to be purchased and an amount equal to any applicable
transfer tax, by cash, certified check or official bank check payable to the
order of the Company or the Rights Agent, the Rights Agent shall, subject to
Section 20(k), thereupon promptly (i) requisition from any transfer agent of the
Preferred Stock (or make available if the Rights Agent is the transfer agent)
certificates for the number of shares of Preferred Stock so elected to be
purchased and the Company will comply and hereby authorizes and directs such
transfer agent to comply with all such requests, (ii) requisition from the
Company the amount of cash to be paid in lieu of issuance of fractional shares
in accordance with Section 14(b) hereof, and (iii) promptly after receipt of
such Preferred Stock certificates 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, when appropriate, after
receipt promptly deliver such cash to or upon the order of the registered holder
of such Right Certificate. In the event of a purchase of securities, other than
Preferred Stock, pursuant to Section 11(a) or Section 13 hereof, the Rights
Agent shall promptly take the appropriate actions corresponding to the foregoing
clauses (i) through (iii). In the event that the Company is obligated to issue
other securities of the Company, pay cash and/or distribute other property
pursuant to Section 11(a) hereof, the Company will make all arrangements
necessary so that such other securities, cash and/or other property are
available for distribution by the Rights Agent, if and when appropriate.


                                       10

<PAGE>   13

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

                  (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.

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

         9. Reservation and Availability of Shares of Preferred Stock.

                  (a) The Company covenants and agrees that at all times it will
cause to be reserved and kept available, out of and to the extent of its
authorized and unissued shares of Preferred Stock not reserved for another
purpose (and, following the occurrence of a Triggering Event, other securities)
or held in its treasury, the number of shares of Preferred Stock (and, following
the occurrence of a Triggering Event, other securities) that, as provided in
this Agreement, including Section 11(a)(iii) hereof, will be sufficient to
permit the exercise in full of all outstanding Rights, provided, however, that
the Company shall not be required to reserve and keep available shares of
Preferred Stock or other securities sufficient to permit the exercise in full of
all outstanding Rights pursuant to the adjustments set forth in Section
11(a)(ii), Section 11(a)(iii) or Section 13 hereof unless, and only to the
extent that, the Rights become exercisable pursuant to such adjustments.

                  (b) The Company shall (i) use its best efforts to cause, from
and after such time as the Rights become exercisable, the Rights and all shares
of Preferred Stock (and following the occurrence of a Triggering Event, other
securities) issued or reserved for issuance upon exercise thereof to be reported
by the National Association of Securities Dealers, Inc. 

                                       11


<PAGE>   14

Automated Quotations System ("NASDAQ"), or such other system then in use, and if
the Preferred Stock shall become listed on any national securities exchange, to
cause, from and after such time as the Rights become exercisable, the Rights and
all shares of Preferred Stock (and, following the occurrence of a Triggering
Event, other securities) issued or reserved for issuance upon exercise thereof
to be listed on such exchange upon official notice of issuance upon such
exercise and (ii) if then necessary, to permit the offer and issuance of such
shares of Preferred Stock (and, following the occurrence of a Triggering Event,
other securities), register and qualify such share of Preferred Stock (and,
following the occurrence of a Triggering Event, other securities) under the
Securities Act and any applicable state securities or "blue sky" laws (to the
extent exemptions therefrom are not available), cause such registration
statement and qualifications to become effective as soon as possible after such
filing and keep such registration and qualifications effective until the
Expiration Date of the Rights. The Company may temporarily suspend, for a period
of time not to exceed ninety (90) days, the exercisability of the Rights in
order to prepare and file a registration statement under the Securities Act and
permit it to become effective. Upon any such suspension, the Company shall issue
a public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect. Notwithstanding any provision of this
Agreement to the contrary, the Rights shall not be exercisable in any
jurisdiction unless the requisite qualification in such jurisdiction shall have
been obtained and until a registration statement under the Securities Act (if
required) shall have been declared effective.

                  (c) The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all shares of Preferred Stock
(and following the occurrence of a Triggering Event, other securities) delivered
upon exercise of Rights shall, at the time of delivery of the certificates for
such shares (subject to payment of the Purchase Price in respect thereof), be
duly and validly authorized and issued and fully paid and nonassessable shares
in accordance with applicable law.

                  (d) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any shares of Preferred Stock (or other securities, as the case may be) 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 for Preferred Stock (or other securities, as the case may be) upon
exercise of Rights in a name other than that of, the registered holder of the
Right Certificate, and the Company shall not be required to issue or deliver a
Right Certificate or certificate for Preferred Stock (or other securities, as
the case may be) to a person other than such registered holder 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 satisfaction that no such tax is due.

                                       12

<PAGE>   15

         10. Preferred Stock Record Date. Each Person in whose name any
certificate for shares of Preferred Stock (or other securities, as the case may
be) is issued upon the exercise of Rights shall for all purposes be deemed to
have become the holder of record of the shares of Preferred Stock (or other
securities, as the case may be) 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, as such, shall not be entitled to any rights
of a stockholder of the Company with respect to the shares for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

         11. Adjustments to Number and Kind of Shares, Number of Rights or
Purchase Price. The number and kind of shares subject to purchase upon the
exercise of each Right, the number of Rights outstanding and the Purchase Price
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 Rights Agreement (A) declare or pay any dividend on Preferred Stock
payable in shares of Preferred Stock, (B) subdivide or split the outstanding
shares of Preferred Stock into a greater number of shares, (C) combine or
consolidate the outstanding shares of Preferred Stock into a smaller number of
shares or effect a reverse split of the outstanding shares of Preferred Stock,
or (D) issue any shares of its capital stock in a reclassification of the
Preferred Stock (including any such reclassification in connection with a
consolidation or merger in which the Company is the continuing or surviving
corporation), except as otherwise provided in this Section 11(a), the Purchase
Price in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination or reclassification, and the
number and kind of shares of Preferred Stock or capital stock, as the case may
be, issuable on such date, shall be proportionately adjusted so that the holder
of any Right exercised after such time shall be entitled to receive, upon
payment of the Purchase Price then in effect, the aggregate number and kind of
shares of capital stock or other securities, which, if such Right had been
exercised immediately prior to such date, the holder thereof would have owned
upon such exercise and been entitled to receive by virtue of such dividend,
subdivision, combination or reclassification. If an event occurs which would
require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii)
hereof, 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 Section 24, in the event

                           (A) any Acquiring Person or any Associate or
Affiliate of any Acquiring Person at any time after the date of this Agreement,
directly or indirectly, (1) shall consolidate with or merge with and into the
Company or any of its Subsidiaries or otherwise combine with the Company or any
of its Subsidiaries and the Company or such Subsidiary shall be the continuing
or surviving corporation of such consolidation, merger or combination and the
Common Stock of the Company shall remain outstanding and no shares thereof shall
be changed 

                                       13

into or exchanged for stock or other securities of the Company or of any other
Person or cash or any other property, or (2) shall, in one or more transactions,
other than in connection with the exercise of a Right or Rights and other than
in connection with the exercise or conversion of securities exercisable for or
convertible into securities of the Company or of any Subsidiary of the Company,
transfer any assets or property to the Company or any of its Subsidiaries in
exchange (in whole or in part) for any shares of any class of capital stock of
the Company or any of its Subsidiaries or any securities exercisable for or
convertible into shares of any class of capital stock of the Company or any of
its Subsidiaries, or otherwise obtain from the Company or any of its
Subsidiaries, with or without consideration, any additional shares of any class
of capital stock of the Company or any of its Subsidiaries or any securities
exercisable for or convertible into shares of any class of capital stock of the
Company or any of its Subsidiaries (other than as part of a pro rata offer or
distribution by the Company or such Subsidiary to all holders of such shares),
or (3) shall sell, purchase, lease, exchange, mortgage, pledge, transfer or
otherwise acquire (other than as a pro rata dividend) or dispose, to, from or
with, as the case may be, in one transaction or a series of transactions, the
Company or any of its Subsidiaries, assets (including securities) on terms and
conditions less favorable to the Company or such Subsidiary than the Company or
such Subsidiary would be able to obtain in arm's-length negotiation with an
unaffiliated third party, or (4) shall receive any compensation from the Company
or any of its Subsidiaries for services other than compensation for employment
as a regular or part-time employee, or fees for serving as a director, at rates
in accordance with the Company's (or its Subsidiary's) past practices, or (5)
shall receive the benefit, directly or indirectly (except proportionately as a
stockholder), of any loans, advances, guarantees, pledges or other financial
assistance or any tax credits or tax advantage provided by the Company or any of
its Subsidiaries, or (6) shall engage in any transaction with the Company (or
any of its Subsidiaries) involving the sale, license, transfer or grant of any
right in, or disclosure of, any patents, copyrights, trade secrets, trademarks,
know-how or any other intellectual or industrial property rights recognized
under any country's intellectual property laws which the Company (including its
Subsidiaries) owns or has the right to use on terms and conditions not approved
by the Board; or

                           (B) any Person, alone or together with its Affiliates
and Associates, shall become an Acquiring Person (except pursuant to a tender or
exchange offer for all outstanding shares of Common Stock at a price and on
terms determined by at least a majority of the members of the Board of Directors
who are not officers of the Company and are not Acquiring Persons or Affiliates
or Associates thereof to be in the best interests of the Company and its
stockholders (other than the Person or an Affiliate or Associate thereof on
whose behalf the offer is being made) (a "Permitted Offer")); or

                           (C) during such time as there is an Acquiring Person,
there shall be any reclassification of securities (including any reverse stock
split), or any recapitalization of the Company, or any merger or consolidation
of the Company with any of its Subsidiaries or any other transaction or series
of transactions involving the Company or any of its Subsidiaries (whether or not
with or into or otherwise involving an Acquiring Person or any Affiliate or
Associate of such Acquiring Person) which has the effect, directly or
indirectly, of increasing by more than 1% the proportionate share of the
outstanding shares of any class of

                                       14


<PAGE>   17

equity securities of the Company or any of its Subsidiaries, or securities
exercisable for or convertible into equity securities of the Company or any of
its Subsidiaries, which is directly or indirectly beneficially owned by any
Acquiring Person or any Affiliate or Associate of any Acquiring Person (any of
(A), (B) or (C) being referred to herein as a "Flip-In Event"), then upon the
first occurrence of such Flip-In Event (A) the Purchase Price shall be adjusted
to be the Purchase Price in effect immediately prior to the Flip-In Event
multiplied by the number of one one-hundredth of a share of Preferred Stock for
which a Right was exercisable immediately prior to such Flip-In Event, whether
or not such Right was then exercisable, and (B) each holder of a Right, except
as otherwise provided in this Section 11(a)(ii) and Section 11(a)(iii) hereof,
shall thereafter have the right to receive, upon exercise thereof at a price
equal to the Purchase Price (as so adjusted), in accordance with the terms of
this Agreement and in lieu of shares of Preferred Stock, such number of shares
of Common Stock as shall equal the result obtained by dividing the Purchase
Price (as so adjusted) by 50% of the Current Market Price per share of the
Common Stock (determined pursuant to Section 11(d) hereof) on the date of such
Flip-In Event; provided, however, that the Purchase Price (as so adjusted) and
the number of shares of Common Stock so receivable upon the exercise of a Right
shall, following the Flip-In Event, be subject to further adjustment as
appropriate in accordance with Section 11(f) hereof. Notwithstanding anything in
this Agreement to the contrary, however, from and after the Flip-In Event, any
Rights that are beneficially owned by (x) any Acquiring Person (or any Affiliate
or Associate of any Acquiring Person), (y) a transferee of any Acquiring Person
(or any such Affiliate or Associate) who becomes a transferee after the Flip-In
Event or (z) a transferee of any Acquiring Person (or any such Affiliate or
Associate) who became a transferee prior to or concurrently with the Flip-In
Event pursuant to either (I) a transfer from the Acquiring Person to holders of
its equity securities or to any Person with whom it has any continuing
agreement, arrangement or understanding regarding the transferred Rights or (II)
a transfer which the Board of Directors has determined is part of a plan,
arrangement or understanding which has the purpose or effect of avoiding the
provisions of this paragraph, and subsequent transferees of such Persons, shall
be void without any further action and any holder of such Rights shall
thereafter have no rights whatsoever with respect to such Rights under any
provision of this Agreement. The Company shall use all reasonable efforts to
ensure that the provisions of this Section 11(a)(ii) are complied with, but
shall have no liability to any holder of Right Certificates or other Person as a
result of its failure to make any determinations with respect to an Acquiring
Person or its Affiliates, Associates or transferees hereunder. From and after
the Flip-In Event, no Right Certificate shall be issued pursuant to Section 3 or
Section 6 hereof that represents Rights that are or have become void pursuant to
the provisions of this paragraph, and any Right Certificate delivered to the
Rights Agent that represents Rights that are or have become void pursuant to the
provisions of this paragraph shall be canceled.

                      (iii) The Company may at its option substitute for a share
of Common Stock issuable upon the exercise of Rights in accordance with the
foregoing subparagraph (ii) such number or fractions of shares of Preferred
Stock having an aggregate current market value equal to the Current Market Price
of a share of Common Stock. In the event that there shall not be sufficient
shares of Common Stock issued but not outstanding or authorized but unissued to
permit the exercise in full of the Rights in accordance with the foregoing
subparagraph (ii), the Board of Directors shall, to the extent permitted by
applicable law and any material agreements 


                                       15


<PAGE>   18

then in effect to which the Company is a party (A) determine the excess (such
excess, the "Spread") of (1) the value of the shares of Common Stock issuable
upon the exercise of a Right in accordance with the foregoing subparagraph (ii)
(the "Current Value") over (2) the Purchase Price (as adjusted in accordance
with the foregoing subparagraph (ii)), and (B) with respect to each Right (other
than Rights which have become void pursuant to the foregoing subparagraph (ii)),
make adequate provision to substitute for the shares of Common Stock issuable in
accordance with the foregoing paragraph (ii) upon exercise of the Right and
payment of the Purchase Price (as adjusted in accordance therewith), (1) cash,
(2) a reduction in such Purchase Price, (3) shares of Preferred Stock or other
equity securities of the Company (including, without limitation, shares or
fractions of shares of preferred stock which, by virtue of having dividend,
voting and liquidation rights substantially comparable to those of the shares of
Common Stock, are deemed in good faith by the Board of Directors to have
substantially the same value as the shares of Common Stock (such shares of
Preferred Stock and shares or fractions of shares of preferred stock are
hereinafter referred to as "Common Stock Equivalents", (4) debt securities of
the Company, (5) other assets, or (6) any combination of the foregoing, having a
value which, when added to the value of the shares of Common Stock actually
issued upon exercise of such Right, shall have an aggregate value equal to the
Current Value (less the amount of any reduction in such Purchase Price), where
such aggregate value has been determined by the Board of Directors upon the
advice of a nationally recognized investment banking firm selected in good faith
by the Board of Directors; provided, however, that if the Company shall not make
adequate provision to deliver value pursuant to clause (B) above within thirty
(30) days following the Flip-In Event (the "Flip-in Trigger Date"), then the
Company shall be obligated to deliver, to the extent permitted by applicable law
and any material agreements then in effect to which the Company is a party, upon
the surrender for exercise of a Right and without requiring payment of such
Purchase Price, shares of Common Stock (to the extent available), and then, if
necessary, such number or fractions of shares of Preferred Stock (to the extent
available) and then, if necessary, cash, which shares and/or cash have an
aggregate value equal to the Spread. If the Board of Directors of the Company
shall determine in good faith that it is likely that sufficient additional
shares of Common Stock and/or Common Stock Equivalents 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 Flip-In Trigger Date, in order that the Company may seek
stockholder approval for the authorization of such additional shares or Common
Stock Equivalents (such thirty (30) day period, as it may be extended, is herein
called the "Substitution Period"). To the extent that the Company determines
that some action need be taken pursuant to the second and/or third sentence of
this Section 11(a)(iii), the Company (x) shall provide, subject to the last
sentence 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 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 the first sentence of Section 11(a)(iii) and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement stating that the exercisability of the Rights
has been temporarily suspended, as well as a public announcement at such time as
the suspension is no longer in effect. For purposes of this Section 11(a)(iii),
the value of the Common Stock shall be the Current Market Price per share of the
Common Stock on the Flip-In Trigger Date and the per share or per unit 

                                       16




<PAGE>   19

value of any Common Stock Equivalent shall be deemed to equal the Current
Market Price per share of the Common Stock on such date. The Board of Directors
may, but shall not be required to, establish procedures to allocate the right to
receive Common Stock upon the exercise of the Rights among holders of Rights
pursuant to this Section 11(a)(iii).

                  (b) In case the Company shall fix a record date for the
issuance of rights (other than the Rights), options or warrants to all holders
of Preferred Stock entitling them to subscribe for or purchase (for a period
expiring within forty-five calendar days after such record date) Preferred
Stock, shares having the same rights, privileges and preferences as the
Preferred Stock ("equivalent preferred stock") or securities convertible into
Preferred Stock or equivalent preferred stock at a price per share of Preferred
Stock or equivalent preferred stock (or having a conversion price per share, if
a security convertible into Preferred Stock or equivalent preferred stock) less
than the Current Market Price per share of Preferred Stock on such record date,
the Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the number of shares of Preferred
Stock outstanding on such record date, plus the number of shares of Preferred
Stock which the aggregate offering price of the total number of shares of
Preferred Stock and/or equivalent preferred stock (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such Current Market Price, and the denominator of which shall be the number
of shares of Preferred Stock outstanding on such record date, plus the number of
additional shares of Preferred Stock and/or equivalent preferred stock to be
offered for subscription or purchase (or into which the convertible securities
so to be offered are initially convertible). In case such subscription price may
be paid by delivery of consideration part or all of which may be in a form other
than cash, the value of such non-cash consideration shall be as determined in
good faith by the Board of Directors of the Company, whose determination shall
be described in a statement filed with the Rights Agent. Shares of Preferred
Stock 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 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 a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash, assets (other than a
dividend payable in Preferred Stock, but including any dividend payable in stock
other than Preferred Stock) or subscription rights or warrants (excluding those
referred to in Section 11(b) hereof), the Purchase Price to be in effect after
such record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the Current Market Price per share of Preferred Stock 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 cash, assets or evidences of
indebtedness to be distributed or of such subscription rights or warrants
applicable to a share of Preferred Stock and the denominator of which shall be
such Current Market Price per share of Preferred Stock. Such 

                                       17



<PAGE>   20

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 be
adjusted to be the Purchase Price which would have been in effect if such record
date had not been fixed.

                  (d) (i) For the purpose of any computation hereunder, other
than computations made pursuant to Section 11(a)(iii) hereof, the "Current
Market Price" per share of Common Stock on any date shall be deemed to be the
average of the daily closing prices per share of the Common Stock for the thirty
consecutive Trading Days (as such term is hereinafter defined) immediately prior
to such date, and for purpose of computations made pursuant to Section
11(a)(iii) hereof, the "Current Market Price" per share of the Common Stock on
any date shall be deemed to be the average of the daily closing prices per share
of the Common Stock for the ten consecutive Trading Days immediately following
such date; provided, however, that in the event that the Current Market Price
per share of the Common Stock is determined during a period following the
announcement by the issuer of the Common Stock of (i) any dividend or
distribution on the Common Stock (other than a regular quarterly cash dividend
and other than the Rights), (ii) any subdivision, combination or
reclassification of the Common Stock, and prior to the expiration of the
requisite thirty Trading Day or ten Trading Day period, as set forth above,
after the ex-dividend date for such dividend or distribution, or the record date
for such subdivision, combination or reclassification occurs, then, and in each
such case, the Current Market Price shall be properly adjusted to take into
account ex-dividend trading. The closing price for each day shall be the last
sale price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the shares of Common Stock are not listed or admitted to trading on the New
York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the shares of Common Stock are listed or admitted
to trading or, if the shares of Common Stock are not listed or admitted to
trading on any national securities exchange, the last quoted sale 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 shares of Common Stock are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Common Stock selected by the
Board of Directors of the Company. If on any such date no market maker is making
a market in the Common Stock, the fair value of such shares on such date as
determined in good faith by the Board of Directors of the Company shall be used
and shall be binding on the Rights Agent. The term "Trading Day" shall mean a
day on which the principal national securities exchange on which the shares of
Common Stock are listed or admitted to trading is open for the transaction of
business or, if the shares of Common Stock are not listed or admitted to trading
on any national securities exchange, a Business Day. If the Common Stock is not
publicly held or not so listed or traded, "Current Market Price" per share 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 and shall be conclusive for all purposes.

                                       18
<PAGE>   21

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

                  (e) Anything herein to the contrary notwithstanding, no
adjustment in the Purchase Price shall be required unless such adjustment would
require an increase or decrease of at least one percent 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 ten-thousandth of a share of Common Stock
or other share or one-hundred-thousandth of a share of Preferred Stock, as the
case may be. Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which mandates such
adjustment, or (ii) the Expiration Date.

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

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


                                       19

<PAGE>   22

                  (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-hundredth of a share of Preferred Stock (calculated to the nearest
one-hundred-thousandth) obtained by (i) multiplying (x) the number of one
one-hundredth of a share of Preferred Stock covered by a Right immediately prior
to this adjustment, by (y) the Purchase Price in effect immediately prior to
such adjustment of the Purchase Price, and (ii) dividing the product so obtained
by the Purchase Price in effect immediately after such adjustment of the
Purchase Price.

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

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


                                       20


<PAGE>   23

                  (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the shares of
Common Stock, Preferred Stock or other capital stock issuable upon exercise of
the Rights, the Company shall take any corporate action, including using its
best efforts to obtain any required stockholder approvals, which may, in the
opinion of its counsel, be necessary in order that the Company may validly and
legally issue fully paid and nonassessable shares of Common Stock, Preferred
Stock or other capital stock at such adjusted Purchase Price. If upon any
exercise of the Rights, a holder is to receive a combination of Common Stock and
Common Stock Equivalents, a portion of the consideration paid upon such
exercise, equal to at least the then par value of a share of Common Stock of the
Company, shall be allocated as the payment for each share of Common Stock of the
Company so received.

                  (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuance to the holder of any Right exercised after such record date
the shares of Preferred Stock and other capital stock or securities of the
Company, if any, issuable upon such exercise over and above the shares of
Preferred Stock and other capital stock or securities of the Company, if any,
issuable upon such exercise on the basis of the Purchase Price in effect prior
to such adjustment; provided, however, that the Company shall deliver to such
holder a due bill or other appropriate instrument evidencing such holder's right
to receive such additional shares of Preferred Stock and other capital stock or
securities 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 in their good faith judgment the Board of
Directors of the Company shall determine to be advisable in order that any (i)
consolidation or subdivision of the Preferred Stock, (ii) issuance for cash of
any shares of Preferred Stock at less than the Current Market Price, (iii)
issuance for cash of shares of Preferred Stock or securities which by their
terms are convertible into or exchangeable for shares of Preferred Stock, (iv)
stock dividends or (v) issuance of rights, options or warrants referred to in
this Section 11, hereafter made by the Company to holders of its Preferred Stock
shall not be taxable to such stockholders.

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

                                       21



<PAGE>   24

distribution of Rights previously owned by such Person or any of its Affiliates
and Associates. The Company shall not consummate any such consolidation, merger
or sale unless prior thereto the Company and such other Person shall have
executed and delivered to the Rights Agent a supplemental agreement evidencing
compliance with this subsection.

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

                  (p) Anything in this Agreement to the contrary
notwithstanding, in the event that the Company shall at any time after the
Record Date and prior to the Distribution Date (i) declare or pay any dividend
on the outstanding shares of Common Stock payable in shares of Common Stock,
(ii) subdivide the outstanding shares of Common Stock, or (iii) combine the
outstanding shares of Common Stock into a smaller number of shares, the number
of Rights associated with each share of Common Stock then outstanding, or issued
or delivered thereafter, shall be proportionately adjusted so that the number of
Rights thereafter associated with each share of Common Stock following any such
event equals the result obtained by multiplying the number of Rights associated
with each share of Common Stock immediately prior to such event by a fraction,
the numerator or which shall be the number of shares of Common Stock outstanding
immediately prior to the occurrence of such event and the denominator of which
shall be the number of shares of Common Stock outstanding immediately following
the occurrence of such event.

         12. Certification of Adjustments. Whenever an adjustment is made as
provided in Sections 11 and 13 hereof, the Company shall (a) promptly prepare a
certificate signed by its Chief Executive Officer, its President or any Vice
President and by the Treasurer or any Assistant Treasurer or the Secretary or
any Assistant Secretary of the Company setting forth such adjustment and a brief
statement of the facts giving rise to such adjustment, (b) promptly file with
the Rights Agent and with each transfer agent for the Preferred Stock and the
Common Stock a copy of such certificate and (c) mail a brief summary thereof to
each holder of a Right Certificate (or, if prior to the Distribution Date, to
each holder of a certificate representing shares of Common Stock) in accordance
with Section 26 hereof. Notwithstanding the foregoing sentence, the failure of
the Company to give such notice shall not affect the validity of or the force or
effect of or the requirement for such adjustment. The Rights Agent shall be
fully protected in relying on any certificate prepared by the Company pursuant
to Sections 11 and 13 and on any adjustment therein contained and shall not be
deemed to have knowledge of any such adjustment unless and until it shall have
received such certificate. Any adjustment to be made pursuant to Sections 11 and
13 of this Rights Agreement shall be effective as of the date of the event
giving rise to such adjustment.

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

                  (a) In the event that following the first occurrence of a
Flip-In Event, directly or indirectly, (x) the Company shall consolidate with,
or merge with and into, any other Person or Persons and the Company shall not be
the surviving or continuing corporation of such consolidation or merger, or (y)
any Person or Persons shall consolidate with, or merge with and into, the
Company, and the Company shall be the continuing or surviving corporation of
such consolidation or merger and, in connection with such consolidation or
merger, all or part of the outstanding shares of Common Stock shall be changed
into or exchanged for stock or other securities of any other Person or of the
Company or cash or any other property other than, in the case of the
transactions described in subparagraphs (x) or (y), a merger or consolidation
which would result in all of the Voting Power represented by the securities of
the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into securities of the
surviving entity) all of the Voting Power represented by the securities of the
Company or such surviving entity outstanding immediately after such merger or
consolidation and the holders of such securities not having changed as a result
of such transactions), or (z) the Company or one or more of its Subsidiaries
shall sell, mortgage or otherwise transfer to any other Person or any Affiliate
or Associate of such Person, in one transaction, or a series of related
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole), then, on
the first occurrence of any such event (a "Flip-Over Event"), proper provision
shall be made so that (i) each holder of a Right (other than Rights which have
become void pursuant to Section 11(a)(ii) hereof) shall thereafter have the
right to receive, upon the exercise thereof at the Purchase Price (as
theretofore adjusted in accordance with Section 11(a)(ii) hereof), in accordance
with the terms of this Agreement and in lieu of shares of Preferred Stock or
Common Stock of the Company, such number of validly authorized and issued, fully
paid, non-assessable and freely tradeable shares of Common Stock of the
Principal Party (as such term is hereinafter defined), not subject to any liens,
encumbrances, rights of first refusal or other adverse claims, as shall equal
the result obtained by dividing the Purchase Price (as theretofore adjusted in
accordance with Section 11(a)(ii) hereof) by 50% of the Current Market Price per
share of the Common Stock of such Principal Party (determined pursuant to
Section 11(d) hereof) on the date of consummation of such consolidation, merger,
sale or transfer; provided, however, that the Purchase Price (as theretofore
adjusted in accordance with Section 11(a)(ii) hereof) and the number of shares
of Common Stock of such Principal Party so receivable upon exercise of a Right
shall be subject to further adjustment as appropriate in accordance with Section
11(f) hereof to reflect any events occurring in respect of the Common Stock of
such Principal Party after the occurrence of such consolidation, merger, sale or
transfer; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such Flip-Over Event, all the obligations and duties of the
Company pursuant to this Rights Agreement; (iii) the term "Company" for all
purposes of this Rights Agreement shall thereafter be deemed to refer to such
Principal Party, it being specifically intended that the provisions of Section
11 hereof shall only apply to such Principal Party following the first
occurrence of a Flip-Over Event; and (iv) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
shares of its Common Stock in accordance with Section 9 hereof) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof 

                                       23



<PAGE>   26

shall thereafter be applicable, as nearly as reasonably may be, in relation to
its shares of Common Stock thereafter deliverable upon the exercise of the
Rights; provided, however, that, upon the subsequent occurrence of any merger,
consolidation, sale of all or substantially all assets, recapitalization,
reclassification of shares, reorganization or other extraordinary transaction in
respect of such Principal Party, each holder of a Right shall thereupon be
entitled to receive, upon exercise of a Right, such cash, shares, rights,
warrants and other property which such holder would have been entitled to
receive had he, at the time of such transaction, owned the shares of Common
Stock of the Principal Party purchasable upon the exercise of a Right, and such
Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property.

                  (b) "Principal Party" shall mean

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

                           (ii) in the case of any transaction described in (z)
of the first sentence in Section 13(a) hereof, the Person that is the party
receiving the greatest portion of the assets or earning power transferred
pursuant to such transaction or transactions, or, if each Person that is a party
to such transaction or transactions receives the same portion of the assets or
earning power so transferred or if the Person receiving the greatest portion of
the assets or earning power cannot be determined, whichever of such Persons as
is the issuer of Common Stock having the greatest aggregate market value of
shares outstanding; provided, however, that in any such case described in the
foregoing (b)(i) or (b)(ii), (1) if the Common Stock of such Person is not at
such time and has not been continuously over the preceding 12-month period
registered under Section 12 of the Exchange Act, and such Person is a direct or
indirect Subsidiary of another Person the Common Stock of which is and has been
so registered, the term "Principal Party" shall refer to such other Person, or
(2) if such Person is a Subsidiary, directly or indirectly, of more than one
Person, the Common Stocks of all of which are and have been so registered, the
term "Principal Party" shall refer to whichever of such Persons is the issuer of
the Common Stock having the greatest market value of shares outstanding, or (3)
if such Person is owned, directly or indirectly, by a joint venture formed by
two or more Persons that are not owned, directly or indirectly, by the same
Person, the rules set forth in clauses (1) and (2) above shall apply to each of
the owners having an interest in the joint venture as if the Person owned by the
joint venture was a Subsidiary of both or all of such joint 

                                       24



<PAGE>   27
venturers, and the Principal Party in each such case shall bear the obligations
set forth in this Section 13 in the same ratio as its interest in such Person
bears to the total of such interests.

                  (c) The Company shall not consummate any consolidation,
merger, sale or transfer referred to in Section 13(a) unless the Principal Party
shall have a sufficient number of authorized shares of its Common Stock that
have not been issued or reserved for issuance to permit the exercise in full of
the Rights in accordance with this Section 13 and unless prior thereto the
Company and the Principal Party involved therein shall have executed and
delivered to the Rights Agent an agreement confirming that the requirements of
Sections 13(a) and (b) hereof shall promptly be performed in accordance with
their terms and that such consolidation, merger, sale or transfer of assets
shall not result in a default by the Principal Party under this Rights Agreement
as the same shall have been assumed by the Principal Party pursuant to Sections
13(a) and (b) hereof and further providing that, as soon as practicable after
executing such agreement pursuant to this Section 13, the Principal Party at its
own expense shall:

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

                           (ii) use its best efforts, if the Common Stock of the
Principal Party shall become listed on a national securities exchange, to list
(or continue the listing of) the Rights and the securities purchasable upon
exercise of the Rights on such securities exchange and, if the Common Stock of
the Principal Party shall not be listed on a national securities exchange, to
cause the Rights and the securities purchased upon exercise of the Rights to be
reported by NASDAQ or such other system then in use;

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

                           (iv) obtain waivers of any rights of first refusal or
preemptive rights in respect of the shares of Common Stock of the Principal
Party subject to purchase upon exercise of outstanding Rights.

In the event that any of the transactions described in Section 13(a) hereof
shall occur at any time after the occurrence of a transaction described in
Section 11(a)(ii) hereof, the Rights which have not theretofore been exercised
shall thereafter be exercisable in the manner described in Section 13(a).

                                       25

<PAGE>   28

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

                  (e) Notwithstanding anything in this Rights Agreement to the
contrary, Section 13 shall not be applicable to a transaction described in
subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is
consummated with a Person or Persons who acquired shares of Common Stock
pursuant to a Permitted Offer (or a wholly owned subsidiary of any such Person
or Persons), (ii) the price per share of Common Stock offered in such
transaction is not less than the price per share of Common Stock paid to all
holders of Common Stock whose shares were purchased pursuant to such Permitted
Offer and (iii) the form of consideration being offered to the remaining holders
of Common Stock pursuant to such transaction is the same as the form of
consideration paid pursuant to such Permitted Offer. Upon consummation of any
such transaction contemplated by this subsection (e), all Rights hereunder shall
expire.

         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 holders of record of
the Right Certificates with regard to which such fractional Rights would
otherwise be issuable, an amount in cash equal to the same fraction of the then
current market value of a whole Right. For the purposes of this Section 14(a),
the then current market value of a Right shall be determined in the same manner
as the Current Market Price of a share of Common Stock shall be determined
pursuant to Section 11(d) hereof.

                  (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral multiples of
one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates which evidence fractional shares of Preferred Stock
(other fractions which are integral multiples of one one-hundredth of a share of
Preferred Stock). Fractions of shares of Preferred Stock in integral multiples
of one one-hundredth of a share of Preferred Stock may, at the election of the


                                       26


<PAGE>   29

Company, be evidenced by depositary receipts, pursuant to an appropriate
agreement between the Company and a depositary selected by it, provided that
such agreement shall provide that the holders of such depositary receipts shall
have all the rights, privileges and preferences to which they are entitled as
beneficial owners of the shares of Preferred Stock represented by such
depositary receipts. In lieu of fractional shares of Preferred Stock that are
not integral multiples of one one-hundredth of a share of Preferred Stock, the
Company may pay to the registered holders of Right Certificates at the time such
Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one one-hundredth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market value of
one one-hundredth of a share of Preferred Stock shall be the Current Market
Price of a share of Common Stock (as determined pursuant to Section 11(d)(ii)
hereof) for the Trading Day immediately prior to the date of such exercise.

                  (c) Following the occurrence of a Flip-In Event, the Company
shall not be required to issue fractions of shares or units of Common Stock or
Common Stock Equivalents or other securities upon exercise of the Rights or to
distribute certificates which evidence fractional shares of such Common Stock or
Common Stock Equivalents or other securities. In lieu of fractional shares or
units of such Common Stock or Common Stock Equivalents or other securities, the
Company may pay to the registered holders of Right Certificates at the time such
Rights are exercised as herein provided an amount in cash equal to the same
fraction of the Current Market Value of a share or unit of such Common Stock or
Common Stock Equivalent or other securities. For purposes of this Section 14(c),
the Current Market Value shall be determined in the manner set forth in Section
11(d) hereof for the Trading Day immediately prior to the date of such exercise
and, if such Common Stock Equivalent is not traded, each such Common Stock
Equivalent shall have the value of one one-hundredth of a share of Preferred
Stock.

                  (d) The holder of a Right by the acceptance of a Right
expressly waives his right to receive any fractional Right or any fractional
shares upon exercise of a Right.

         15. Rights of Action. All rights of action in respect of this
Agreement, other than any rights of action vested in the Rights Agent pursuant
to Sections 18 and 20 below, are vested in the respective holders of record of
the Right Certificates (and, prior to the Distribution Date, the holders of
record of the Common Stock); and any holder of record of any Right Certificate
(or, prior to the Distribution Date, of the Common Stock), without the consent
of the Rights Agent or of the holder of any other Right Certificate (or, prior
to the Distribution Date, of the Common Stock), may, in his own behalf and for
his own benefit, enforce, and may institute and maintain any suit, action or
proceeding against the Company or any other Person 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,
accordingly, that they 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. Holders of Rights
shall be entitled to recover the reasonable costs and 


                                       27


<PAGE>   30

expenses, including attorneys' fees, incurred by them in any action to enforce
the provisions of this Agreement.

         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 not be
evidenced by a Right Certificate and will be transferable only in connection
with the transfer of Common Stock;

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

                  (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 Certificate or the associated Common Stock
certificate made by anyone other than the Company or the Rights Agent or the
transfer agent of the Common Stock) for all purposes whatsoever, and neither the
Company nor the Rights Agent shall be affected by any notice to the contrary;
and

                  (d) notwithstanding anything in this Agreement to the
contrary, neither the Company nor the Rights Agent shall have any liability to
any holder of a Right or other Person as a result of its inability to perform
any of its obligations under this Agreement by reason of any preliminary or
permanent injunction or other order, decree or ruling issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency
or commission, or any statute, rule, regulation or executive order promulgated
or enacted by any governmental authority, prohibiting or otherwise restraining
performance of such obligation; provided, however, that the Company must use its
best efforts to have any such order, decree or ruling lifted or otherwise
overturned as soon as possible.

         17. Right Certificate Holder Not Deemed a Stockholder. No holder of a
Right, as such, shall be entitled to vote, receive dividends in respect of or be
deemed for any purpose to be the holder of Common Stock or any other securities
of the Company which may at any time be issuable upon the exercise of the
Rights, 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 in 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 in respect
of any such stock or securities, or otherwise, until the Right or Rights
evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

         18. Concerning the Rights Agent.

                  (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all service 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 Rights
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability or expense incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent for any thing done or omitted
to be done by the Rights Agent in connection with the acceptance and
administration of this Rights Agreement, including the cost and expenses of
defending against any claim of liability in the premises. The indemnity provided
herein shall survive the expiration of the Rights and the termination of this
Rights Agreement. Anything in this agreement to the contrary notwithstanding, in
no event shall the Rights Agent be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Rights Agent has been advised of the likelihood of such
loss damage and regardless of the form of action.

                  (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 Rights Agreement in reliance upon any
Right Certificate, certificate for Common Stock or 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, guaranteed, verified or acknowledged, by the proper Person or
Persons.

         19. Merger or Consolidation or Changed 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 or stock transfer business of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent under
this Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto, provided that such corporation would
be eligible for appointment as a successor Rights Agent under the provisions of
Section 21 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.



                                       29

<PAGE>   32

                  (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 such 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
Certificate shall have the full force provided in the Right Certificates and in
this Rights Agreement.

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

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

                  (b) Whenever in the performance of its duties under this
Rights Agreement the Rights Agent shall deem it necessary or desirable that any
fact or matter (including, without limitation, the identity of any Acquiring
Person and the determination of "Current Market Price") be proved or established
by the Company prior to taking 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
certificate signed by the President or any Vice President and by the Treasurer
or any Assistant Treasurer or the Secretary or any Assistant Secretary of the
Company and delivered to the Rights Agent; and such certificate shall be full
authorization to the Rights Agent for any action taken or suffered in good faith
by it under the provisions of this Rights Agreement in reliance upon such
certificate.

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

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

                  (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Rights 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 Rights Agreement or in any Right
Certificate; nor shall it be responsible for any adjustment required under the
provisions of Sections 11, 13, 23 or 24 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 receipt of a
Certificate furnished pursuant to Section 12 describing any such adjustment);
nor shall it by any act hereunder be 


                                       30


<PAGE>   33

deemed to make any representation or warranty as to the authorization or
reservation of any shares of Common Stock to be issued pursuant to this Rights
Agreement or any Right Certificate or as to whether any shares of Common Stock
will, when issued, be validly authorized and issued, fully paid and
nonassessable.

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

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
the Chairman of the Board, the Chief Executive Officer, the President or any
Vice President or the Secretary or any Assistant Secretary or the Treasurer or
any Assistant Treasurer of the Company, and to apply to such officers for advice
or instructions in connection with its duties, and it shall not be liable for
any action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer. Any application by the Rights Agent for
written instructions from the Company may, at the option of the Rights Agent,
set forth in writing any action proposed to be taken or omitted by the Rights
Agent under this Rights Agreement and the date on and/or after which such action
shall be taken or such omission shall be effective. Subject to Section 20(c)
hereof, the Rights Agent shall not be liable for any action taken by, or
omission of, the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date shall
not be less than five Business Days after the date any officer of the Company
actually receives such application, unless any such officer shall have consented
in writing to an earlier date) unless, prior to taking any such action (or the
effective date in the case of an omission), the Rights Agent shall have received
written instructions in response to such application specifying the action to be
taken or omitted.

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


                                       31

<PAGE>   34

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

                  (k) If, with respect to any Right Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate contained in the form
of assignment or the form of election to purchase set forth on the reverse
thereof, as the case may be, has either not been completed or indicates an
affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not
take any further action with respect to such requested exercise of transfer
without first consulting with the Company.

         21. Change of Rights Agent. The Rights Agent or any successor Rights
Agent may resign and be discharged from its duties under this Rights Agreement
upon 30 days' notice in writing, or such earlier period as shall be agreed to in
writing, mailed to the Company and to each transfer agent of the Common Stock 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 (with or without cause) upon 30 days' notice in writing, or such
earlier period as shall be agreed to 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 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. Notwithstanding the foregoing provisions of this
Section 21, in no event shall the resignation or removal of a Rights Agent be
effective until a successor Rights Agent shall have been appointed and have
accepted such appointment. If the Company shall fail to make such appointment
within a period of 30 days after such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of a Right Certificate (who shall, with such
notice, submit his Right Certificate for inspection by the Company), then the
incumbent Rights Agent or the holder of record of any Right Certificate may
apply to any court of competent jurisdiction for the appointment of a new Rights
Agent. Any successor Rights Agent, whether appointed by the Company or by such a
court, shall be (a) a corporation organized and doing business under the laws of
the United States or any State thereof, in good standing, which is authorized
under such laws to exercise corporate trust or stock transfer powers and is
subject to supervision or examination by federal or state authority and which
has at the time of its appointment as Rights Agent a combined capital and
surplus of at least $50,000,000 or (b) an Affiliate controlled by a corporation
described in clause (a) of this sentence. 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 mail a notice thereof in
writing to the registered holders of the Right 


                                       32



<PAGE>   35

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.

22. Issuance of New Right Certificates. Notwithstanding any of the provisions of
this Rights 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 per share and the number or kind or class of shares of stock or
other securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Rights Agreement. In addition, in
connection with the issuance or sale of shares of Common Stock following the
Distribution Date and prior to the redemption or expiration of the Rights, the
Company shall, with respect to shares of Common Stock so issued or sold pursuant
to the exercise of stock options or under any employee plan or arrangement, or
upon the exercise, conversion or exchange of securities hereinafter issued by
the Company, in each case existing prior to the Distribution Date, issue Right
Certificates representing the appropriate number of Rights in connection with
such issuance or sale; provided, however, that (i) no such Right Certificate
shall be issued if, and to the extent that, the Company shall be advised by
counsel that such issuance would create a significant risk of material adverse
tax consequences to the Company or the Person to whom such Right Certificate
would be issued, and (ii) no such Right Certificate shall be issued, if, and to
the extent that, appropriate adjustment shall otherwise have been made in lieu
of the issuance thereof.

         23. Redemption.

                  (a)      (i) The Board of Directors of the Company may, at its
option, at any time prior to the earlier of (x) the first occurrence of a
Flip-In Event or (y) the Close of Business on the Expiration Date, redeem all
but not less than all the then outstanding Rights at a redemption price of
$0.001 per Right, as such amount may be appropriately adjusted to reflect any
stock split, stock dividend or similar transaction occurring after the date
hereof (such redemption price being hereinafter referred to as the "Redemption
Price").

                           (ii) In addition, and notwithstanding the provisions
of Section 23(a)(i), the Board of Directors of the Company may redeem all but
not less than all of the then outstanding Rights at the Redemption Price
following the Stock Acquisition Date but prior to any event described in Section
13(a) either (x) in connection with any event specified in Section 13(a) in
which all holders of Common Stock are treated alike and not involving (other
than as a holder of Common Stock being treated like all other such holders) an
Acquiring Person or an Affiliate or Associate thereof or any other Person in
which such Acquiring Person or Affiliate or Associate thereof has any interest,
or any other Person acting directly or indirectly on behalf of or in association
with any such Acquiring Person or Affiliate or Associate thereof, or (y)
following the occurrence of an event set forth in, and the expiration of any
period during which the holder of Rights may exercise the rights under, Section
11(a)(ii) if and for as long as any Acquiring Person having triggered such event
is not thereafter the Beneficial Owner of securities representing 15% or more of
the outstanding shares of Common Stock, and at the time of redemption there are
no other Persons who are Acquiring Persons.


                                       33

<PAGE>   36

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the redemption of the Rights (or at such later time as the
Board of Directors may establish for the effectiveness of such redemption), and
without any further action and without any notice, the right to exercise the
Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price. The Company shall promptly give public
notice of any such redemption; provided, however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within (10) days after such action of the Board of Directors ordering the
redemption of the Rights (or such later time as the Board of Directors may
establish for the effectiveness of such redemption), the Company shall mail a
notice of redemption to all the holders of the then outstanding Rights at their
last addresses as they appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Stock. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of redemption shall state the method by which the payment of the Redemption
Price will be made. The failure to give notice required by this Section 23(b) or
any defect therein shall not affect the legality or validity of the action taken
by the Company.

                  (c) In the case of a redemption permitted under Section 23(a),
the Company may, at its option, discharge all of its obligations with respect to
the Rights by (i) issuing a press release announcing the manner of redemption of
the Rights and (ii) mailing payment of the Redemption Price to the registered
holders of the Rights at their last addresses as they appear on the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent of the Common Stock, and upon such action, all
outstanding Right Certificates shall be null and void without any further action
by the Company.

         24. Exchange of Rights for Common Stock.

                  (a) The Board of Directors of the Company may, at its option,
at any time after the occurrence of a Flip-In Event, exchange all or part of the
then outstanding and exercisable Rights (which (i) shall not include Rights that
have become void pursuant to the provisions of Section 11(a)(ii) and (ii) shall
include, without limitation, any Rights issued after the Distribution Date in
accordance with Section 22) 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 an Exempt Person),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of shares of Common Stock aggregating 50% or more of the shares
of Common Stock then outstanding. From and after the occurrence of an event
specified in Section 13(a) hereof, any Rights that theretofore have not been
exchanged pursuant to this Section 24(a) shall thereafter be exercisable only in
accordance with Section 13 and may not be exchanged pursuant to this Section
24(a).


                                       34

<PAGE>   37

                  (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 the Rights Agent.
Any notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will
state the method by which the exchange of the shares of Common Stock for Rights
will be effected and, in the event of any partial exchange, the number of Rights
which will be exchanged. Any partial exchange shall be effected pro rata based
on the number of Rights (other than Rights which have become void pursuant to
the provisions of Section 11(a)(ii) hereof) held by each holder of Rights.

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

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

                  (e) The Company shall not be required to issue fractions of
shares of Common Stock or to distribute certificates which evidence fractional
shares of Common Stock. In lieu of such fractional shares of Common Stock, the
Company shall pay to the registered holders of the Right Certificates with
regard to which such fractional shares of Common Stock would otherwise be
issuable an amount in cash equal to the same fraction of the current market
value of a whole share of Common Stock. For the purposes of this paragraph (d),
the current market value of a whole share of Common Stock shall be the Current
Market Price of a share of Common Stock (as defined in Section 11(d) hereof for
the purposes of computations made other than pursuant to Section 11(a)(iii)) for
the Trading Day immediately prior to the date of exchange pursuant to this
Section 24.

to pay any dividend to the holders of record of its Preferred Stock payable in
stock of any class or to make any other distribution to the holders of record of
its Preferred Stock (other than a regular periodic cash dividend), or (ii) to
offer to the holders of record of its Preferred Stock or options, warrants, or
other rights to subscribe for or to purchase shares of Preferred Stock
(including any security convertible into or exchangeable for Preferred Stock) or
shares of stock of any other class or any other securities, options, warrants,
convertible or exchangeable securities or other rights, or (iii) to effect any
reclassification of its Preferred Stock or any recapitalization or
reorganization of the Company, or (iv) to effect any consolidation or merger

transactions, of more than 50% of the assets or earning power of the Company and
its Subsidiaries (taken as a whole) to, any other Person or Persons, or (v) to
effect the liquidation, dissolution or winding up of the Company, then, in each
such case, the Company shall give to each holder of record of a Right

action, which shall specify the record date for the purposes of such transaction

transaction, shall similarly give notice thereof to each holder of Rights.

                  (c) The failure to give notice required by this Section 25 or
any defect therein shall not affect the legality or validity of the action taken
by the Company or the vote upon any such action.

be given or made by the Rights Agent or by the holder of record of any Right
Certificate or Right to or on behalf of the Company shall be sufficiently given

shall be construed to give to any person or corporation other than the Company,

holders of record of the Right Certificates (and, prior to the Distribution
Date, the Common Stock).

                           TRIDENT MICROSYSTEMS, INC.

                                  CERTIFICATE
                     OF DESIGNATION, PREFERENCES AND RIGHTS
                              OF THE TERMS OF THE
                            SERIES A PREFERRED STOCK


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

         We, the President and Chief Executive Officer and Secretary,
respectively, of Trident Microsystems, Inc., organized and existing under the
General Corporation Law of the State of Delaware, in accordance with the
provisions of Section 103 thereof, DO HEREBY CERTIFY:

         That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the said Corporation, the said Board of
Directors on July 24, 1998, adopted the following resolution creating a series
of 300,000 shares of Preferred Stock designated as Series A Preferred Stock:

         RESOLVED, that pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock of the Corporation be
and it hereby is created, and that the designation and amount thereof and the
powers, preferences and relative, participating, optional and other special
rights of the shares of such series, and the qualifications, limitations or
restrictions thereof are as follows:

         Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Preferred Stock" (the "Series A Preferred Stock"),
$0.001 par value per share, and the number of shares constituting such series
shall be 300,000.

         Section 2. Dividends and Distributions.

                  (A) The dividend rate on the shares of Series A Preferred
Stock shall be for each quarterly dividend (hereinafter referred to as a
"quarterly dividend period"), which quarterly dividend periods shall commence on
January 1, April 1, July 1 and October 1 each year (each such date being
referred to herein as a "Quarterly Dividend Payment Date") (or in the case of
original issuance, from the date of original issuance) and shall end on and
include the day next preceding the first date of the next quarterly dividend
period, at a rate per quarterly dividend period (rounded to the nearest cent)
equal to the greater of (a) $125.00 or (b) subject to the provisions for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
cash, based upon the fair market value at the time the non-cash dividend or
other distribution is declared as determined in good faith by the Board of
Directors) of all non-cash dividends or other distributions other than a 

                                       1

<PAGE>   43

dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared (but not
withdrawn) on the Common Stock, par value $0.001 per share, of the Corporation
(the "Common Stock") during the immediately preceding quarterly dividend period,
or, with respect to the first quarterly dividend period, since the first
issuance of any share or fraction of a share of Series A Preferred Stock. In the
event this Company shall at any time after August 14, 1998 (the "Rights
Declaration Date") (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  (B) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares of Series A
Preferred Stock, unless the date of issue of such shares is prior to the record
date for the first Quarterly Dividend Payment Date, in which case dividends on
such shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive a quarterly dividend and before such Quarterly
Dividend Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but
unpaid dividends shall not bear interest. Dividends paid on the shares of Series
A Preferred Stock in an amount less than the total amount of such dividends at
the time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors may fix a record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than 45 days
prior to the date fixed for the payment thereof.

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

                  (A) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 100 votes on all matters submitted to a vote of the stockholders of the
Corporation. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the 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.


                                       2


<PAGE>   44

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

                  (C) Except as set forth herein, in the Certificate of
Incorporation and in the By-laws, 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. 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
to be created by resolution or resolutions of the Board of Directors, subject to
the conditions and restrictions on issuance set forth herein.

         Section 5. Liquidation, Dissolution or Winding Up.

                  (A) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of the Series A
Preferred Stock shall be entitled to receive the greater of (a) $5,000.00 per
share, plus accrued dividends to the date of distribution, whether or not earned
or declared, or (b) an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount to be distributed
per share to holders of Common Stock. In the event the Corporation shall at any
time after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event pursuant to clause
(b) of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

         Section 6. 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 the shares of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of shares
of Series A Preferred Stock 

                                       3



<PAGE>   45

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

         Section 8. Fractional Shares. Series A Preferred Stock may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and have the benefit of all other rights of holders
of Series A Preferred Stock. All payments made with respect to fractional shares
hereunder shall be rounded to the nearest whole cent.

         Section 9. 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 on, make any other
distributions on, or redeem or purchase or otherwise acquire for consideration
any shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Preferred Stock;

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

                           (iii) redeem or purchase or otherwise acquire for
consideration shares of any stock ranking on a parity (either as to dividends or
upon liquidation, dissolution or winding up) with the Series A Preferred Stock,
provided that the Corporation may at any time redeem, purchase or otherwise
acquire shares of any such parity stock in exchange for shares of any stock of
the Corporation ranking junior (either as to dividends or upon dissolution,
liquidation or winding up) to the Series A Preferred Stock; or

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

<PAGE>   46

                  (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 9, purchase or otherwise acquire such shares at such time and in
such manner.

         Section 10. Ranking. The Series A Preferred Stock shall be junior to
all other Series of the Corporation's preferred stock as to the payment of
dividends and the distribution of assets, unless the terms of any series shall
provide otherwise.

         Section 11. Amendment. The Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of
two-thirds or more of the outstanding shares of Series A Preferred Stock voting
together as a single class.

         IN WITNESS WHEREOF, we have executed and subscribed this Certificate
and do affirm the foregoing as true under the penalties of perjury this 14th day
of August, 1998.

principal office of the Rights Agent, or its successors as Rights Agent,
designated for such purposes, one one-hundredth of a fully paid and
nonassessable share of Series A Preferred Stock of the Company ("Preferred
Stock") at a purchase price of $50.00 per one one-hundredth of a share, as the
same may from time to time be adjusted in accordance with the Rights Agreement
("Purchase Price"), upon presentation and surrender of this Right Certificate
with the Form of Election to Purchase duly executed. Capitalized terms used
herein and not otherwise defined herein shall have the meanings ascribed to such
terms in the Rights Agreement.

<PAGE>   48

         As provided in the Rights Agreement, the Purchase Price and the number
of shares of Preferred Stock or other securities which may be purchased upon the
exercise of the Rights evidenced by this Right Certificate are subject to
modification and adjustment upon the happening of certain events and, upon the
happening of certain events, securities other than shares of Preferred Stock, or
other property, may be acquired upon exercise of the Rights evidenced by this
Right Certificate, as provided by the Rights Agreement.

         Upon the occurrence of a Flip-In Event, if the Rights evidenced by this
Rights Certificate are beneficially owned by (i) an Acquiring Person or an
Affiliate or Associate of any such Acquiring Person, (ii) a transferee of any
such Acquiring Person, Associate or Affiliate, or (iii) under certain
circumstances specified in the Rights Agreement, a transferee of a person who,
after such transfer, became an Acquiring Person, or any Affiliate or Associate
of an Acquiring Person, such Rights shall be null and void and will no longer be
transferable and no holder hereof shall have any right with respect to such
Rights from and after the occurrence of such Flip-In Events.

         This Right Certificate is subject to all the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
incorporated herein by reference and made a part hereof and to which Rights
Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities of the Rights Agent,
the Company and the holders of record of the Right Certificates, which
limitation of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the principal executive office of
the Company and are available upon written request to the Company.

         This Right Certificate, with or without other Right Certificates, upon
surrender at the principal office of the Rights Agent, may be exchanged for
another Right Certificate or Right 

                                       2
<PAGE>   49

Certificates of like tenor and date evidencing Rights entitling the holder of
record to purchase a like aggregate number of shares of Preferred Stock as the
Rights evidenced by the Right Certificate or Right Certificates surrendered
shall have entitled such holder to purchase. If this Right Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender
hereof, another Right Certificate or Right Certificates for the number of whole
Rights not exercised.
 
        Subject to the provisions of the Rights Agreement, at any time prior to
the earlier of (i) the occurrence of a Flip-In Event (as such term is defined in
the Rights Agreement) or (ii) the Expiration Date (as such term is defined in
the Rights Agreement), the Rights evidenced by this Certificate may be redeemed
by the Company at its option at a redemption price of $0.001 per Right. Subject
to the provisions of the Rights Agreement, the Company may, at its option, at
any time after a Flip-In Event, exchange all or part of the Rights evidenced by
this Certificate for shares of the Company's Common Stock or for Preferred Stock
(or shares of a class or series of the Company's preferred stock having the same
rights, privileges and preferences as the Preferred Stock).

         In the event (i) any person or group becomes an Acquiring Person or
(ii) any of the types of transactions, acquisitions or other events described
above as self-dealing transactions occur, and prior to the acquisition by such
person or group of 50% or more of the outstanding shares of Common Stock, the
Board may require all or any portion of the outstanding Rights (other than
Rights owned by such Acquiring Person which have become void) to be exchanged
for Common Stock on a pro rata basis, at an exchange ratio of one share of
Common Stock or one one-hundredth of a share of Preferred Stock (or of a share
of a class or series of the Company's Preferred Stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

         No fractional shares of Preferred Stock shall be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a 


                                       3

<PAGE>   50
share of Preferred Stock, which may, at the option of the Company, be evidenced
by depositary receipts), and no fractional shares of Common Stock will be issued
upon the exchange of any Right or Rights evidenced hereby, and in lieu thereof,
as provided in the Rights Agreement, fractions of shares of Preferred Stock or
Common Stock shall receive an amount in cash equal to the same fraction of the
then Current Market Price (as such term is defined in the Rights Agreement) of a
share of Preferred Stock or Common Stock, as the case may be.

         No holder of this Right Certificate, as such, shall be entitled to vote
or receive dividends or be deemed for any purpose the holder of Common Stock or
of any other securities of the Company which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote in 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 (other than certain actions specified in
the Rights Agreement) or to receive dividends or subscription rights, or
otherwise, until the Right or Rights evidenced by this Right Certificate shall
have been exercised or exchanged as provided in the Rights Agreement.

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

UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS ISSUED
TO, BENEFICIALLY OWNED BY OR TRANSFERRED TO ANY PERSON WHO IS OR BECOMES AN
ACQUIRING PERSON (AS DEFINED IN THE RIGHTS AGREEMENT) OR AN ASSOCIATE OR
AFFILIATE (AS DEFINED IN THE RIGHTS AGREEMENT) THEREOF AND CERTAIN TRANSFEREES
THEREOF WILL BE NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                           TRIDENT MICROSYSTEMS, INC.

                               SUMMARY OF TERMS OF
                                RIGHTS AGREEMENT



NATURE OF RIGHT:           When exercisable, each Right (a "Right") will
                           initially entitle the holder to purchase one
                           one-hundredth of a share of Series A Preferred Stock
                           ("Preferred Stock") of Trident Microsystems, Inc.
                           (the "Company").

MEANS OF DISTRIBUTION:     The Rights will be distributed to holders of the
                           Company's outstanding Common Stock (the "Common
                           Stock") as a dividend of one Right for each share of
                           Common Stock. The Rights will also be attached to all
                           future issuances of Common Stock prior to the 
                           Distribution Date (as defined below).

EXERCISABILITY:            Rights become exercisable on the earlier of: (i) the
                           tenth day following the date of public announcement
                           by the Company or by any person or group (an
                           "Acquiring Person") that such person or group has
                           acquired beneficial ownership of 15% or more of the
                           Company's outstanding Common Stock, or (ii) the tenth
                           business day (unless extended by the Board prior to
                           the time a person becomes an Acquiring Person)
                           following the commencement, or announcement of an
                           intention to commence, by any person or group of a
                           tender or exchange offer which would result in such
                           person owning 15% or more of the outstanding Common
                           Stock of the Company (the earlier of such dates is
                           referred to as the "Distribution Date"), provided
                           that an Acquiring Person does not include an Exempt
                           Person (as such term is defined in the Rights
                           Agreement). Rights will trade separately from the
                           Common Stock once the Rights become exercisable. The
                           Board of Directors (the "Board") of the Company may
                           extend the periods specified in subsections (i) and
                           (ii) above by up to three (3) consecutive periods of
                           ten (10) days each.

EXERCISE PRICE:            $50.00 per share, which is the amount that in the
                           judgment of the Board represents the long-term value
                           of the Common Stock over the term of the Rights 
                           Agreement (the "Purchase Price").


                                       1


<PAGE>   57

TERM:                      The Rights will expire upon the earlier of (i) July
                           23, 2008 or (ii) redemption or exchange by the
                           Company as described below.

REDEMPTION OF RIGHTS:      Rights are redeemable at a price of $0.001 per Right,
                           by the vote of the Board, at any time until the 
                           occurrence of a Flip-In Event (defined below).

PREFERRED STOCK:           The Preferred Stock purchasable upon exercise of the
                           Rights will be nonredeemable and junior to any other
                           series of preferred stock the Company may issue
                           (unless otherwise provided in the terms of such other
                           series). Each share of Preferred Stock will have a
                           preferential cumulative quarterly dividend in an
                           amount equal to the greater of (a) $125.00 or (b) 100
                           times the dividend declared on each share of Common
                           Stock. In the event of liquidation, the holders of
                           Preferred Stock will receive a preferred liquidation
                           payment equal to the greater of (a) $5,000.00 per
                           share, plus accrued dividends to the date of
                           distribution whether or not earned or declared, or
                           (b) an amount per share equal to 100 times the
                           aggregate payment to be distributed per share of
                           Common Stock. Each share of Preferred Stock shall
                           entitle the holder thereof to 100 votes, voting
                           together with the shares of Common Stock. In the
                           event of any merger, consolidation or other
                           transaction in which shares of Common Stock are
                           exchanged for or changed into other securities, cash
                           and/or other property, each share of Preferred Stock
                           will be entitled to receive 100 times the amount and
                           type of consideration received per share of Common
                           Stock. The rights of the Preferred Stock as to
                           dividends, liquidation and voting, and in the event
                           of mergers and consolidations, are protected by
                           customary anti-dilution provisions. Fractional shares
                           (in integral multiples of one one-hundredth) of
                           Preferred Stock will be issuable; however, the
                           Company may elect to distribute depositary receipts
                           in lieu of such fractional shares. In lieu of
                           fractional shares other than fractions that are
                           multiples of one one-hundredth of a share, an
                           adjustment in cash will be made based on the market
                           price of the Preferred Stock on the last trading date
                           prior to the date of exercise. Because of the nature
                           of the Preferred Stock's dividend, liquidation and
                           voting rights, the value of one one-hundredth of a

                           TRIDENT MICROSYSTEMS, INC.
                         ADOPTS SHAREHOLDERS RIGHTS PLAN

         Mountain View, California, July 27 -- Trident Microsystems, Inc.
("Trident") announced today that on the evening of July 24, 1998 its Board of
Directors has adopted a Preferred Stock Purchase Rights Plan designed to enable
all Trident's stockholders to realize the full value of their investment and to
provide for fair and equal treatment for all Trident's stockholders in the event
that an unsolicited attempt is made to acquire Trident. The adoption of the Plan
is intended as a means to guard against any potential use of takeover tactics
designed to gain control of Trident without paying all stockholders full and
fair value. The distribution of the Rights is not in response to any proposal to
acquire Trident. The Board is not aware of any such effort.

         Under the plan, stockholders will receive one Right to purchase one
one-hundredth of a share of a new series of Preferred Stock for each outstanding
share of Trident's Common Stock held of record at the close of business on
August 14, 1998.

         The Rights, which will initially trade with the Common Stock, become
exercisable to purchase one one-hundredth of a share of the new Preferred Stock,
at $50 per Right, when someone acquires 15 percent or more of Trident's Common
Stock or announces a tender offer

                              [TRIDENT LETTERHEAD]

                                August 18, 1998

Dear Fellow Stockholders:

     Trident Microsystems, Inc.'s Board of Directors has adopted a Shareholder
Rights Plan (the "Plan"). We have attached a summary of the principal terms of
the Plan and we urge you to read it carefully.

     The Plan is designed to protect your interests in the event the Company is
confronted with an unsolicited takeover attempt. The Plan contains provisions
designed to deter unsolicited offers that do not treat all stockholders equally,
acquisitions of significant blocks of shares in the open market without paying a
control premium and other coercive takeover tactics which may impair the Board's
ability to represent your interests fully. These tactics unfairly pressure
stockholders, squeeze them out of their investment without giving them any real
choice and deprive them of the full value of their shares of the Company's
Common Stock. The Plan is similar to plans adopted by over 1,500 publicly held
companies, and was adopted by the Board of Directors after consultation with the
Company's investment bankers and counsel. We consider the Plan to be an
effective tool in protecting your equity investment, while not preventing a fair
acquisition offer.

     The Plan is not intended to prevent a takeover of the Company and will not
do so. It is designed to deal with unilateral actions by a hostile acquiror that
are calculated to deprive the Board of Directors and the Company's stockholders
of the ability to take actions to maximize stockholder value. The Plan does not
preclude the Board of Directors from considering or accepting an offer to
acquire all or part of the Company, if the Board of Directors believes the offer
to be in the best interests of the Company's stockholders. The Plan has not been
adopted in response to any known effort to acquire control of the Company.

     The adoption of the Plan does not weaken the financial strength of the
Company or interfere with its business plans. The issuance of the Rights has no
dilutive effect, will not affect reported earnings per share, is not taxable to
the Company or you, and will not change the way in which you can trade the
Company's common stock. As explained in detail in the enclosed summary of the
Plan, the Rights can only be exercised if and when a situation arises which the
Plan was created to address.

     You are not required to take any action at this time. We recommend,
however, that you read the attached summary of the many features of the Plan,
and retain the summary with your Trident Microsystems, Inc. stock certificates
or records. If you should require further information, a copy of the Plan can
be obtained from the Company's Secretary.

     The Board of Directors believes that the adoption of the Plan represents a
sound and reasonable means of preserving the long-term value of the Company for
all of its stockholders. We want to thank all stockholders for their continued
support.

                                        Very truly yours,

                                        /s/ FRANK C. LIN
                                        -------------------------------------
