Item 1.        DESCRIPTION OF SECURITIES TO BE REGISTERED.

                    PREFERRED SHARE PURCHASE RIGHTS

          On July 9, 1998 the Board of Directors of Hilton Hotels Corporation
(the "Company") adopted a Preferred Share Purchase Rights Plan to replace its
existing rights plan which expires on July 27, 1998.

          In connection with the Rights Plan, the Board of Directors of the
Company declared a dividend of one preferred share purchase right (the "Rights")
for each outstanding share of common stock, par value $2.50 per share (the
"Common Shares"), of the Company outstanding at the close of business on July
27, 1998 (the "Record Date").  Each Right will entitle the registered holder
thereof, after the Rights become exercisable and until July 27, 2008 (or the
earlier redemption, exchange or termination of the Rights), to purchase from the
Company one one-hundredth (1/100th) of a share of Series A Junior Participating
Preferred Stock, par value $1.00 per share (the "Preferred Shares"), at a price
of $140 per one one-hundredth (1/100th) of a Preferred Share, subject to certain
anti-dilution adjustments (the "Purchase Price").

          Until the earlier to occur of (i) ten (10) days following a public
announcement that a person or group of affiliated or associated persons has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the Common Shares (an "Acquiring Person") or (ii) ten (10) business days (or
such later date as may be determined by action of the Board of Directors prior
to such time as any person or group of affiliated persons becomes an Acquiring
Person) following the commencement or announcement of an intention to make a
tender offer or exchange offer the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the Common Shares
(the earlier of (i) and (ii) being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate.  The Rights
will be transferred with and only with the Common Shares until the Distribution
Date or earlier redemption or expiration of the Rights.  Barron Hilton and The
Conrad N. Hilton Fund will not be deemed "Acquiring Persons" under the Rights
Plan.

          As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Shares as of the close of business on the
Distribution Date and such separate Right Certificates alone will evidence the
Rights.  The Rights will at no time have any voting rights.

          Each Preferred Share purchasable upon exercise of the Rights will be
entitled, when, as and if declared, to a minimum preferential quarterly dividend
payment of $1.00 per share but will be entitled to an aggregate dividend of 100
times the dividend, if any, declared per Common Share.  In the event of
liquidation, dissolution or winding up of the Company, the holders of the
Preferred Shares will be entitled to a preferential liquidation payment of $100
per share plus any accrued but unpaid dividends but will be entitled to an
aggregate payment of 100 times the payment made per Common Share.  Each
Preferred Share will have 100 votes and will vote together with the Common
Shares.  Finally, in the event of any merger, consolidation or


                                          2
<PAGE>

other transaction in which Common Shares are exchanged, each Preferred Share
will be entitled to receive 100 times the amount received per Common Share.
Preferred Shares will not be redeemable.  These Rights are protected by
customary anti-dilution provisions.  Because of the nature of the Preferred
Share's dividend, liquidation and voting rights, the value of one one-hundredth
of a Preferred Share purchasable upon exercise of each Right should approximate
the value of one Common Share.

          In the event that a Person becomes an Acquiring Person or if the
Company were the surviving corporation in a merger with an Acquiring Person or
any affiliate or associate of an Acquiring Person and the Common Shares were not
changed or exchanged, each holder of a Right, other than Rights that are or were
acquired or beneficially owned by the Acquiring Person (which Rights will
thereafter be void), will thereafter have the right to receive upon exercise
that number of Common Shares having a market value of two times the then current
Purchase Price of one Right.  In the event that, after a person has become an
Acquiring Person, the Company were acquired in a merger or other business
combination transaction or more than 50% of its assets or earning power were
sold, proper provision shall be made so that each holder of a Right shall
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction would have a market
value of two times the then current Purchase Price of one Right.

          At any time after a Person becomes an Acquiring Person and prior to
the earlier of one of the events described in the last sentence in the previous
paragraph or the acquisition by such Acquiring Person of 50% or more of the then
outstanding Common Shares, the Board of Directors may cause the Company to
exchange the Rights (other than Rights owned by an Acquiring Person which have
become void), in whole or in part, for Common Shares having an aggregate value
equal to the difference between the value of the Common Shares issuable upon
exercise of the Rights and the Purchase Price payable upon such exercise.

          The Rights may be redeemed in whole, but not in part, at a price of
$.001 per Right (the "Redemption Price") by the Board of Directors at any time
prior to the close of business on the 10th day following the first date of
public announcement that an Acquiring Person has become such, and may under
certain circumstances redeem the Rights after a person has become an Acquiring
Person.  The redemption of the Rights may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish. Immediately upon any redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price.

          The Rights will expire at the close of business on July 27, 2008
(unless earlier redeemed, exchanged or terminated).  ChaseMellon Shareholder
Services, L.L.C. is the Rights Agent.

          The Purchase Price payable, and the number of one one-hundredths of a
Preferred Share or other securities or property issuable, upon exercise of the
Rights are subject to adjustment from time to time to prevent dilution (i) in
the event of a stock dividend on, or a


                                          3
<PAGE>

subdivision, combination or reclassification of, the Preferred Shares, (ii) upon
the grant to holders of the Preferred Shares of certain rights or warrants to
subscribe for or purchase Preferred Shares or convertible securities at less
than the current market price of the Preferred Shares or (iii) upon the
distribution to holders of the Preferred Shares of evidences of indebtedness,
cash, securities or assets (excluding regular periodic cash dividends at a rate
not in excess of 125% of the rate of the last regular periodic cash dividend
theretofore paid or, in case regular periodic cash dividends have not
theretofore been paid, at a rate not in excess of 50% of the average net income
per share of the Company for the four quarters ended immediately prior to the
payment of such dividend, or dividends payable in Preferred Shares (which
dividends will be subject to the adjustment described in clause (i) above)) or
of subscription rights or warrants (other than those referred to above).

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

          Any of the provisions of the Rights Agreement dated as of July 9, 1998
between the Company and the Rights Agent (the "Rights Agreement") may be amended
by the Board of Directors of the Company for so long as the Rights are then
redeemable, and after the Rights are no longer redeemable, the Company may amend
or supplement the Rights Agreement in any manner that does not adversely affect
the interests of the holder of the Rights.

          One Right will be distributed to stockholders of the Company for each
Common Share owned of record by them on July 27, 1998.  As long as the Rights
are attached to the Common Shares, the Company will issue one Right with each
new Common Share so that all such shares will have attached Rights.  The Company
has agreed that, from and after the Distribution Date, the Company will reserve
3,000,000 Preferred Shares initially for issuance upon exercise of the Rights.

          The Rights are designed to assure that all of the Company's
stockholders receive fair and equal treatment in the event of any proposed
takeover of the Company and to guard against partial tender offers, open market
accumulations and other abusive tactics to gain control of the Company without
paying all stockholders a control premium.  The Rights will cause substantial
dilution to a person or group that acquires 15% or more of the Company's stock
on terms not approved by the Company's Board of Directors.  The Rights should
not interfere with any merger or other business combination approved by the
Board of Directors at any time prior to the first date that a Person or group
has become an Acquiring Person.

          The foregoing description of the Rights is qualified in its entirety
by reference to the Rights Agreement which is attached as an exhibit to this
Form 8-A.

                                   RIGHTS AGREEMENT

          Rights Agreement, dated as of July 9, 1998, between Hilton Hotels
Corporation, a Delaware corporation (the "COMPANY"), and ChaseMellon Shareholder
Services L.L.C., as Rights Agent (the "RIGHTS AGENT").

                                       RECITALS

          WHEREAS, on July 9, 1998, the Board of Directors of the Company
adopted this Agreement, and has authorized and declared a dividend of one
preferred share purchase right (a "RIGHT") for each Common Share (as defined in
Section 1.6) of the Company outstanding at the close of business on July 27,
1998 (the "RECORD DATE") and has authorized and directed the issuance of one
Right (subject to adjustment as provided herein) with respect to each Common
Share that shall become outstanding between the Record Date and the earliest of
the Distribution Date and the Expiration Date (as such terms are defined in
Sections 3.1 and 7.1), each Right initially representing the right to purchase
one one-hundredth (subject to adjustment) of a share of Series A Junior
Participating Preferred Stock (the "PREFERRED SHARES") 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 PROVIDED, HOWEVER, that Rights may be issued
with respect to Common Shares that shall become outstanding after the
Distribution Date and prior to the Expiration Date in accordance with Section
22.

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

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

          1.1.      "ACQUIRING PERSON" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates and Associates
(as such terms are hereinafter defined) of such Person, shall be the Beneficial
Owner (as such term is hereinafter defined) of 15% or more of the Common Shares
of the Company then outstanding but shall not include an Exempt Person (as such
term is hereinafter defined).  Notwithstanding the foregoing, no Person shall
become an "Acquiring Person" as the result of an acquisition of Common Shares by
the Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such Person to 15% or more
of the Common Shares of the Company then outstanding; PROVIDED, HOWEVER, that if
a Person shall become the Beneficial Owner of 15% or more of the Common Shares
of the Company then outstanding solely by reason of share purchases by the
Company and shall, after such share purchases by the Company, become the
Beneficial Owner of one or more additional Common Shares of the Company (other
than pursuant to a dividend or distribution paid or made by the Company on the
outstanding Common Shares in Common Shares or pursuant to a split or subdivision
of the outstanding Common Shares), then such Person shall be deemed to be an
"Acquiring Person" unless upon becoming the Beneficial Owner of such additional
Common Shares of the Company such Person 


                                          1

<PAGE>


does not beneficially own 15% or more of the Common Shares of the Company then
outstanding.  Notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
Section 1.1, has become such inadvertently (including, without limitation,
because (A) such Person was unaware that it beneficially owned a percentage of
Common Stock that would otherwise cause such Person to be an "Acquiring Person"
or (B) such Person was aware of the extent of its Beneficial Ownership of Common
Stock but had no actual knowledge of the consequences of such Beneficial
Ownership under this Agreement), and without any intention of changing or
influencing control of the Company, and such Person divests as promptly as
practicable a sufficient number of Common Shares so that such Person would no
longer be an Acquiring Person, as defined pursuant to the foregoing provisions
of this Section 1.1, then such Person shall not be deemed to be or have become
an "Acquiring Person" at any time for any purposes of this Agreement.  For all
purposes of this Agreement, any calculation of the number of Common Shares
outstanding at any particular time, including for purposes of determining the
particular percentage of such outstanding Common Shares 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 Securities
Exchange Act of 1934, as amended (the "EXCHANGE ACT"), as in effect on the date
of this Agreement.

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

          1.3.      A Person shall be deemed the "BENEFICIAL OWNER" of and
shall be deemed to "BENEFICIALLY OWN" any securities:

                    (i)     which such Person or any of such Person's Affiliates
or Associates beneficially owns, directly or indirectly (as determined pursuant
to Rule 13d-3 of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement);

                    (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,
compliance with regulatory requirements, fulfillment of a condition or
otherwise) pursuant to any agreement, arrangement or understanding, whether or
not in writing (other than customary agreements with and between underwriters
and selling group members with respect to a bona fide public offering of
securities), or upon the exercise of conversion rights, exchange rights, rights,
warrants or options, or otherwise; PROVIDED, HOWEVER, that a Person shall not be
deemed the Beneficial Owner of, or to beneficially own, (w) securities tendered
pursuant to a tender or exchange offer made by or on behalf of such Person or
any of such Person's Affiliates or Associates until such tendered securities are
accepted for purchase or exchange, (x) securities which such Person has a right
to acquire upon the exercise of Rights at any time prior to the time that any
Person becomes an Acquiring Person, (y) securities issuable upon the exercise of
Rights from and after the time that any Person becomes an Acquiring Person if
such Rights were acquired by such Person or any of such Person's Affiliates or
Associates


                                          2

<PAGE>

prior to the Distribution Date or pursuant to Section 3.1 or Section 22
("ORIGINAL RIGHTS") or pursuant to Section 11.9 or Section 11.15 with respect to
an adjustment to Original Rights or (z) securities which such Person or any of
such Person's Affiliates or Associates may acquire, does or do acquire or may be
deemed to have the right to acquire, pursuant to any merger or other acquisition
agreement between the Company and such Person (or one or more of his Affiliates
or Associates) if such agreement has been approved by the Board of Directors of
the Company prior to such Person's becoming an Acquiring Person; or (B) the
right to vote 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 security under this clause (B)
if the agreement, arrangement or understanding to vote such security (1) arises
solely from a revocable proxy or consent given to such Person in response to a
public proxy or consent solicitation made pursuant to, and in accordance with,
the applicable rules and regulations of the Exchange Act and (2) is not also
then reportable on Schedule 13D under the Exchange Act (or any comparable or
successor report); or

                    (iii)   which are beneficially owned, directly or
indirectly, by any other Person (or any Affiliate or Associate thereof) and with
respect to which such Person or any of such Person's Affiliates or Associates
has any agreement, arrangement or understanding (other than customary agreements
with and between underwriters and selling group members with respect to a bona
fide public offering of securities), whether or not in writing, for the purpose
of acquiring, holding, voting (except pursuant to a revocable proxy or consent
as described in the proviso to Section 1.3(ii)(B)) 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 1.3), including, without limitation, in a
fiduciary capacity, by an Exempt Person or by any other such officer, director
or employee of an Exempt Person.

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

          1.5.      "CLOSE OF BUSINESS" on any given date shall mean 5:00 p.m.,
California time, on such date; PROVIDED, HOWEVER, that if such date is not a
Business Day it shall mean 5:00 p.m., California time, on the next succeeding
Business Day.

          1.6.      "COMMON SHARES" when used with reference to the Company
shall mean the shares of common stock, par value $2.50 per share, of the
Company.  "Common Shares" when used with reference to any Person other than the
Company shall mean the capital stock with the greatest voting power, or the
equity securities or other equity interest having power to control or direct the
management, of such other Person or, if such Person is a Subsidiary (as such
term is hereinafter defined) of another Person, the Person or Persons which
ultimately control


                                          3

<PAGE>

          Section 3.        ISSUANCE OF RIGHT CERTIFICATES.

          3.1.      RIGHTS EVIDENCED BY SHARE CERTIFICATES.  Until the earlier
of (i) the tenth day after the Shares Acquisition Date or (ii) the tenth
Business Day after the date of the commencement of, or first public announcement
of the intent of any Person (other than an Exempt Person) to commence, a tender
or exchange offer the consummation of which would result in any Person (other
than an Exempt Person) becoming the Beneficial Owner of Common Shares
aggregating 15% or more of the then outstanding Common Shares of the Company
(the earlier of (i) and (ii) being herein referred to as the "DISTRIBUTION
DATE"), (x) the Rights (unless earlier expired, redeemed or terminated) will be
evidenced (subject to the provisions of Section 3.2) by the certificates for
Common Shares registered in the names of the holders thereof (which certificates
for Common Shares shall also be deemed to be Right Certificates) and not by
separate certificates, and (y) the Rights (and the right to receive certificates
therefor) will be transferable only in connection with the transfer of the
underlying Common Shares.  The preceding sentence notwithstanding, prior to the
occurrence of a Distribution Date specified as a result of an event described in
clause (ii) (or such later Distribution Date as the Board of Directors of the
Company may select pursuant to this sentence), the Board of Directors may
postpone, one or more times, the Distribution Date which would occur as a result
of an event described in clause (ii) beyond the date set forth in such clause
(ii).  Nothing herein shall permit such a postponement of a Distribution Date
after a Person becomes an Acquiring Person, except as a result of the operation
of the third sentence of Section 1.1 or as permitted by Section 23.1.  As soon
as practicable after the Distribution Date, the Company will prepare and
execute, the Rights Agent will countersign and the Company (or, if requested,
the Rights Agent) will send, by first-class, postage-prepaid mail, to each
record holder of Common Shares as of the close of business on the Distribution
Date (other than any Acquiring Person or any Associate or Affiliate of an
Acquiring Person), at the address of such holder shown on the records of the
Company, one or more certificates for Rights, in substantially the form of
Exhibit B hereto (a "RIGHT CERTIFICATE"), evidencing one Right (subject to
adjustment as provided herein) for each Common Share so held.  As of the
Distribution Date, the Rights will be evidenced solely by such Right
Certificates.

          3.2.      SUMMARY OF RIGHTS.  On the Record Date or as soon as 
practicable thereafter, the Company will send or cause to be sent a copy of a 
Summary of Rights to Purchase Preferred Shares, in substantially the form 
attached hereto as Exhibit C (the "SUMMARY OF RIGHTS"), by first-class, 
postage-prepaid mail, to each record holder of Common Shares as of the close 
of business on the Record Date at the address of such holder shown on the 
records of the Company.  With respect to certificates for Common Shares 
outstanding as of the close of business on the Record Date, until the 
Distribution Date (or the earlier Expiration Date), the Rights will be 
evidenced by such certificates for Common Shares registered in the names of 
the holders thereof together with a copy of the Summary of Rights and the 
registered holders of the Common Shares shall also be registered holders of 
the associated Rights.  Until the Distribution Date (or the earlier 
Expiration Date), the surrender for transfer of any certificate for Common 
Shares outstanding at the close of business on the Record Date, with or 
without a copy of the 

                                          6

<PAGE>

Summary of Rights, shall also constitute the transfer of the Rights 
associated with the Common Shares represented thereby.

          3.3.      NEW CERTIFICATES AFTER RECORD DATE.  Certificates for
Common Shares which become outstanding (whether upon issuance out of authorized
but unissued Common Shares, disposition out of treasury or transfer or exchange
of outstanding Common Shares) after the Record Date but prior to the earliest of
the Distribution Date or the Expiration Date, shall have impressed, printed,
stamped, written or otherwise affixed onto them the following legend:

     This certificate also evidences and entitles the holder hereof to
     certain rights as set forth in an Agreement between Hilton Hotels
     Corporation (the "Company") and ChaseMellon Shareholder Services,
     L.L.C., as Rights Agent, dated as of July 9, 1998, as the same may be
     amended from time to time (the "Agreement"), the terms of which are
     hereby incorporated herein by reference and a copy of which is on file
     at the principal executive offices of the Company.  Under certain
     circumstances, as set forth in the Agreement, such Rights will be
     evidenced by separate certificates and will no longer be evidenced by
     this certificate.  The Company will mail to the holder of this
     certificate a copy of the Agreement without charge after receipt of a
     written request therefor.  AS DESCRIBED IN THE AGREEMENT, RIGHTS WHICH
     ARE OWNED BY, TRANSFERRED TO OR HAVE BEEN OWNED BY ACQUIRING PERSONS
     OR ASSOCIATES OR AFFILIATES THEREOF (AS DEFINED IN THE AGREEMENT)
     SHALL BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

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

          Notwithstanding this Section 3.3, the omission of a legend shall not
affect the enforceability of any part of this Agreement or the rights of any
holder of the Rights.

          Section 4.        FORM OF RIGHT CERTIFICATES.  The Right Certificates
(and the forms of election to purchase shares, certification and assignment to
be printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange or trading system on which the Rights may from time to time be listed
or quoted, or to conform to usage.  Subject to the terms and conditions hereof,
the Right Certificates, whenever issued, shall be dated as of the Record Date, 


                                          7

<PAGE>

and shall show the date of countersignature by the Rights Agent, and on their 
face shall entitle the holders thereof to purchase such number of one 
one-hundredths of a Preferred Share as shall be set forth therein at the 
price per one one-hundredth of a Preferred Share set forth therein (the 
"PURCHASE PRICE"), but the number of such one one-hundredths of a Preferred 
Share and the Purchase Price shall be subject to adjustment as provided 
herein.

          Section 5.        COUNTERSIGNATURE AND REGISTRATION. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board of Directors, the Chief Executive Officer, President, any Vice President
or its Treasurer, either manually or by facsimile signature, and shall have
affixed thereto the Company's seal or a facsimile thereof which shall be
attested by the Secretary or any Assistant Secretary of the Company, either
manually or by facsimile signature.  The Right Certificates shall be
countersigned, either manually or by facsimile signature, by an authorized
signatory of the Rights Agent, but it shall not be necessary for the same
signatory to countersign all of the Right Certificates hereunder.  No Right
Certificate shall 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, and issued and delivered
by the Company with the same force and effect as though the person who signed
such Right Certificates had not ceased to be such officer of the Company; and
any Right Certificate may be signed on behalf of the Company by any person who,
at the actual date of the execution of such Right Certificate, shall be a proper
officer of the Company to sign such Right Certificate, although at the date of
the execution of this Agreement any such person was not such an officer.



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

          Section 6.        TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF
RIGHT CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES. 
Subject to the provisions of Section 7.5, Section 11.1.2 and Section 14, at any
time after the close of business on the Distribution Date, and at or prior to
the close of business on the Expiration Date, any Right Certificate or Right
Certificates (other than Right Certificates representing Rights that have become
void pursuant to Section 11.1.2 or that have been exchanged pursuant to Section
27) may be transferred, split up or combined or exchanged for another Right
Certificate or Right Certificates, entitling the registered holder to purchase a
like number of one one-hundredths of a Preferred Share as the Right Certificate
or Right Certificates surrendered then entitled such holder to purchase.  Any
registered holder desiring to transfer, split up or combine or exchange any
Right Certificate shall make such request in writing delivered to the Rights
Agent, and shall surrender, together with any required form of assignment and
certificate duly completed, the Right Certificate or Right Certificates to be
transferred, split up or combined or exchanged at the 


                                          8

<PAGE>

office of the Rights Agent designated for such purpose.  Neither the Rights
Agent nor the Company shall be obligated to take any action whatsoever with
respect to the transfer of any such surrendered Right Certificate or Right
Certificates until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Right Certificate or Right Certificates and shall have provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company shall reasonably request. 
Thereupon the Rights Agent shall countersign and deliver to the person entitled
thereto a Right Certificate or Right Certificates, as the case may be, as so
requested.  The Company may require payment from the holders of Right
Certificates of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer, split up or combination or
exchange of such Right Certificates.

          Subject to the provisions of Section 11.1.2 , at any time after the
Distribution Date and prior to the Expiration Date, upon receipt by the Company
and the Rights Agent of evidence reasonably satisfactory to them of the loss,
theft, destruction or mutilation of a Right Certificate, and, in case of loss,
theft or destruction, of indemnity or security reasonably satisfactory to them,
and, at the Company's request, reimbursement to the Company and the Rights Agent
of all reasonable expenses incidental thereto, and upon surrender to the Rights
Agent and cancellation of the Right Certificate if mutilated, the Company will
make and deliver a new Right Certificate of like tenor to the Rights Agent for
countersignature and delivery to the registered owner in lieu of the Right
Certificate so lost, stolen, destroyed or mutilated.

          Section 7.        EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE
OF RIGHTS.

          7.1.      EXERCISE OF RIGHTS.  Subject to Section 11.1.2 and except
as otherwise provided herein, the registered holder of any Right Certificate may
exercise the Rights evidenced thereby in whole or in part at any time after the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase and certification on the reverse side thereof duly
executed, to the Rights Agent at the office of the Rights Agent designated for
such purpose, together with payment of the aggregate Purchase Price for the
total number of one one-hundredths of a Preferred Share (or other securities,
cash or other assets) as to which the Rights are exercised, at or prior to the
time (the "EXPIRATION DATE") that is the earliest of (i) the close of business
on July 27, 2008 (the "FINAL EXPIRATION DATE"), (ii) the time at which the
Rights are redeemed as provided in Section 23 (the "REDEMPTION DATE"), (iii) the
closing of any merger or other acquisition transaction involving the Company
pursuant to an agreement of the type described in Sections 1.3(ii)(A)(z) and
13.3, at which time the Rights are deemed terminated, or (iv) the time at which
the Rights are exchanged as provided in Section 27.

          7.2.      PURCHASE .  The Purchase Price for each one one-hundredth
of a Preferred Share pursuant to the exercise of a Right shall be initially
$140, shall be subject to adjustment from time to time as provided in Sections
11, 13 and 26 and shall be payable in lawful money of the United States of
America in accordance with Section 7.3.

          7.3.      PAYMENT PROCEDURES.  Upon receipt of a Right Certificate
representing exercisable Rights, with the form of election to purchase and
certification duly executed, 


                                          9

<PAGE>

accompanied by payment of the aggregate Purchase Price for the total number of
one one-hundredths of a Preferred Share to be purchased and an amount equal to
any applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9, in cash or by certified or cashier's
check or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i)(A) requisition from any transfer agent of the Preferred
Shares (or make available, if the Rights Agent is the transfer agent)
certificates for the number of Preferred Shares to be purchased and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests, or (B) if the Company shall have elected to deposit the total number
of Preferred Shares issuable upon exercise of the Rights hereunder with a
depository agent, requisition from the depositary agent depositary receipts
representing interests in such number of one one-hundredths of a Preferred Share
as are to be purchased (in which case certificates for the Preferred Shares
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company hereby directs the depositary agent to comply
with all such requests, (ii) when appropriate, requisition from the Company the
amount of cash to be paid in lieu of the issuance of fractional shares in
accordance with Section 14 or otherwise in accordance with Section 11.1.3, (iii)
promptly after receipt of such certificates or depositary receipts, cause the
same to be delivered to or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be designated by such
holder and (iv) when appropriate, after receipt, promptly deliver such cash to
or upon the order of the registered holder of such Right Certificate.  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 11.1.3, 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.

          7.4.      PARTIAL EXERCISE.  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 and delivered to the registered
holder of such Right Certificate or to his duly authorized assigns, subject to
the provisions of Section 14.

          7.5.      FULL INFORMATION CONCERNING OWNERSHIP.  Notwithstanding
anything in this Agreement to the contrary, neither the Rights Agent nor the
Company shall be obligated to undertake any action with respect to a registered
holder of Rights upon the occurrence of any purported exercise as set forth in
this Section 7 unless the certificate contained in the form of election to
purchase set forth on the reverse side of the Right Certificate surrendered for
such exercise shall have been duly completed and signed by the registered holder
thereof and the Company shall have been provided with such additional evidence
of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company shall reasonably request.

          Section 8.        CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES. 
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in canceled
form, or, if surrendered to the Rights Agent, shall be canceled by it, 


                                          10

<PAGE>

and no Right Certificates shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Agreement.  The Company shall deliver
to the Rights Agent for cancellation and retirement, and the Rights Agent shall
so cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof.  The Rights Agent shall
deliver all canceled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such canceled Right Certificates, and in such
case shall deliver a certificate of destruction thereof to the Company.

          Section 9.        RESERVATION AND AVAILABILITY OF CAPITAL STOCK.  The
Company covenants and agrees that from and after the Distribution Date it will
cause to be reserved and kept available out of its authorized and unissued
Preferred Shares (and, following the occurrence of a Trigger Event, out of its
authorized and unissued Common Shares or other securities or out of its shares
held in its treasury) the number of Preferred Shares (and, following the
occurrence of a Trigger Event, Common Shares and/or other securities) that will
be sufficient to permit the exercise in full of all outstanding Rights.

          So long as the Preferred Shares (and, following the occurrence of a
Trigger Event, Common Shares and/or other securities) issuable upon the exercise
of Rights may be listed on any national securities exchange or traded in the
over-the-counter market and quoted on the National Association of Securities
Dealers, Inc. Automated Quotation System ("NASDAQ") (including the National
Market or Small Cap Market), the Company shall use its best efforts to cause,
from and after such time as the Rights become exercisable, all shares reserved
for such issuance to be listed or admitted to trading on such exchange or quoted
on Nasdaq upon official notice of issuance upon such exercise.

          The Company covenants and agrees that it will take all such action as
may be necessary to ensure that all Preferred Shares (and, following the
occurrence of a Trigger Event, Common Shares  and/or 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), be duly and validly
authorized and issued and fully paid and nonassessable shares.

          From and after such time as the Rights become exercisable, the Company
shall use its best efforts, if then necessary to permit the issuance of
Preferred Shares upon the exercise of Rights, to register and qualify such
Preferred Shares under the Securities Act and any applicable state securities or
"Blue Sky" laws (to the extent exemptions therefrom are not available), cause
such registration statement and qualifications to become effective as soon as
possible after such filing and keep such registration and qualifications
effective until the earlier of the date as of which the Rights are no longer
exercisable for such securities and the Expiration Date.  The Company may
temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file a registration
statement under the Securities Act and permit it to become effective.  Upon any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect. 
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have 


                                          11

<PAGE>

been obtained and until a registration statement under the Securities Act (if
required) shall have been declared effective.

          The Company further covenants and agrees that it will pay when due and
payable any and all Federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares (or Common Shares and/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 the Preferred Shares (or Common Shares and/or other securities,
as the case may be) in a name other than that of, the registered holder of the
Right Certificate evidencing Rights surrendered for exercise or to issue or
deliver any certificates for Preferred Shares (or Common Shares and/or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until any such tax shall have been paid
(any such tax being payable by the holder of such Right Certificate at the time
of surrender) or until it has been established to the Company's satisfaction
that no such tax is due.

          Section 10.       PREFERRED SHARES RECORD DATE.  Each person in whose
name any certificate for Preferred Shares (or Common Shares and/or other
securities, as the case may be) is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares (or Common Shares and/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; PROVIDED,
HOWEVER, that if the date of such surrender and payment is a date upon which the
Preferred Shares (or Common Shares and/or other securities, as the case may be)
transfer books of the Company are closed, such person shall be deemed to have
become the record holder of such shares (fractional or otherwise) on, and such
certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares (or Common Shares and/or other securities, as the case may be)
transfer books of the Company are open.  Prior to the exercise of the Rights
evidenced thereby, the holder of a Right Certificate shall not be entitled to
any rights of a holder of Preferred Shares for which the Rights shall be
exercisable, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided herein.

          Section 11.       ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR
NUMBER OF RIGHTS.  The Purchase Price, the number of Preferred Shares or other
securities or property purchasable upon exercise of each Right and the number of
Rights outstanding are subject to adjustment from time to time as provided in
this Section 11.

          11.1.     POST-EXECUTION EVENTS.

          11.1.1.   CORPORATE DIVIDENDS, RECLASSIFICATIONS, ETC.  In the event
the Company shall at any time after the date of this Agreement (A) declare and
pay a dividend on the Preferred Shares payable in Preferred Shares, (B)
subdivide the outstanding Preferred Shares, (C) combine 


                                          12

<PAGE>

the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11.1, the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification, and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the Company were open, he would have owned
upon such exercise and been entitled to receive by virtue of such dividend,
subdivision, combination or reclassification; PROVIDED, HOWEVER, that in no
event shall the consideration to be paid upon the exercise of one Right be less
than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right.  If an event occurs which would require an
adjustment under both Section 11.1.1 and Section 11.1.2, the adjustment provided
for in this Section 11.1.1 shall be in addition to, and shall be made prior to,
the adjustment required pursuant to, Section 11.1.2.

          11.1.2.   ACQUIRING PERSON EVENTS; TRIGGERING EVENTS.  Subject to
Sections 23.1 and 27, in the event that a Trigger Event occurs, then, from and
after the first occurrence of such event, each holder of a Right, except as
provided below, shall thereafter have a right to receive, upon exercise thereof
at a price per Right equal to the then current Purchase Price multiplied by the
number of one one-hundredths of a Preferred Share for which a Right is then
exercisable (without giving effect to this Section 11.1.2), in accordance with
the terms of this Agreement and in lieu of Preferred Shares, such number of
Common Shares as shall equal the result obtained by (x) multiplying the then
current Purchase Price by the then number of one one-hundredths of a Preferred
Share for which a Right is then exercisable (without giving effect to this
Section 11.1.2) and (y) dividing that product by 50% of the current per share
market price of the Common Shares (determined pursuant to Section 11.4) on the
first of the date of the occurrence of, or the date of the first public
announcement of, a Trigger Event (the "ADJUSTMENT SHARES"); PROVIDED that the
Purchase Price and the number of Adjustment Shares shall thereafter be subject
to further adjustment as appropriate in accordance with Section 11.6; PROVIDED
FURTHER, that nothing contained in this Section 11.1.2 shall limit or otherwise
diminish the power of the Board of Directors to postpone the Distribution Date
pursuant to Section 3.1 or to extend the period during which the Rights may be
redeemed pursuant to Section 23.1.  Notwithstanding the foregoing, upon the
occurrence of a Trigger Event, any Rights that are or were acquired or
beneficially owned by (1) any Acquiring Person or any Associate or Affiliate
thereof, (2) a transferee of any Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person becomes such, or
(3) a transferee of any Acquiring Person (or of any such Associate or Affiliate)
who becomes a transferee prior to or concurrently with the Acquiring Person
becoming such and receives such Rights pursuant to either (A) a transfer
(whether or not for consideration) from the Acquiring Person to holders of
equity interests in such Acquiring Person or to any Person with whom the
Acquiring Person has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which 


                                          13

<PAGE>

the Board of Directors of the Company has determined is part of a plan,
arrangement or understanding which has as a primary purpose or effect avoidance
of this Section 11.1.2, and subsequent transferees, shall become void without
any further action, and any holder (whether or not such holder is an Acquiring
Person or an Associate or Affiliate of an Acquiring Person) of such Rights shall
thereafter have no right to exercise such Rights under any provision of this
Agreement or otherwise.  The Company shall not enter into any transaction of the
type described in this Section 11.1.2 if at the time of such transaction there
are any rights, warrants, instruments or securities outstanding or any
arrangements which, as a result of the consummation of such transaction, would
eliminate or substantially diminish the benefits intended to be afforded by the
Rights.  From and after the Trigger Event, no Right Certificate shal be issued
pursuant to Section 3 or Section 6 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.

          The Company shall use all reasonable efforts to ensure that the
provisions of this Section 11.1.2 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 any Acquiring Person or its
Affiliates, Associates or transferees hereunder.

          From and after the occurrence of an event specified in Section 13.1,
any Rights that theretofore have not been exercised pursuant to this Section
11.1.2 shall thereafter be exercisable only in accordance with Section 13 and
not pursuant to this Section 11.1.2.

          11.1.3.   INSUFFICIENT SHARES.  The Company may at its option
substitute for a Common Share issuable upon the exercise of Rights in accordance
with the foregoing Section 11.1.2 a number of Preferred Shares or fraction
thereof such that the current per share market price of one Preferred Share
multiplied by such number or fraction is equal to the current per share market
price of one Common Share.  In the event that upon the occurrence of one or more
of the events listed in Section 11.1.2 above there shall not be sufficient
Common Shares authorized but unissued, or held by the Company as treasury
shares, to permit the exercise in full of the Rights in accordance with the
foregoing Section 11.1.2, the Company shall take all such action as may be
necessary to authorize additional Common Shares for issuance upon exercise of
the Rights, PROVIDED, HOWEVER, that if the Company determines that it is unable
to cause the authorization of a sufficient number of additional Common Shares,
then, in the event the Rights become exercisable, the Company, with respect to
each Right and to the extent necessary and permitted by applicable law and any
agreements or instruments in effect on the date hereof to which it is a party,
shall:  (A)  determine the excess of (1) the value of the Adjustment Shares
issuable upon the exercise of a Right (the "CURRENT VALUE"), over (2) the
Purchase Price (such excess, the "SPREAD") and (B) with respect to each Right
(other than Rights which have become void pursuant to Section 11.1.2), make
adequate provision to substitute for the Adjustment Shares, upon payment of the
applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3)
Preferred Shares or other equity securities of the Company (including, without
limitation, shares, or fractions of shares, of preferred stock which, by virtue
of having dividend, 




                                          14

<PAGE>

voting and liquidation rights substantially comparable to those of the Common 
Shares, the Board of Directors of the Company has deemed in good faith to 
have substantially the same value as Common Shares) (each such share of 
preferred stock or fractions of shares of preferred stock constituting a 
"COMMON STOCK EQUIVALENT")), (4) debt securities of the Company, (5) other 
assets or (6) any combination of the foregoing having an aggregate value 
equal to the Current Value, where such aggregate value has been determined by 
the Board of Directors of the Company based upon the advice of a nationally 
recognized investment banking firm selected in good faith by the Board of 
Directors of the Company; PROVIDED, HOWEVER, that if the Company shall not 
have made adequate provision to deliver value pursuant to clause (B) above 
within thirty (30) days following the first occurrence of one of the events 
listed in Section 11.1.2 above, then the Company shall be obligated to 
deliver, to the extent necessary and permitted by applicable law and any 
agreements or instruments in effect on the date hereof to which it is a 
party, upon the surrender for exercise of a Right and without requiring 
payment of the Purchase Price, Common Shares (to the extent available) and 
then, if necessary, such number or fractions of Preferred Shares (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 unlikely that sufficient 
additional Common Shares could be authorized for issuance upon exercise in 
full of the Rights, the thirty (30) day period set forth above may be 
extended and re-extended to the extent necessary, but not more than ninety 
(90) days following the first occurrence of one of the events listed in 
Section 11.1.2 above, in order that the Company may seek stockholder approval 
for the authorization of such additional shares (such period as may be 
extended, the "SUBSTITUTION PERIOD").  To the extent that the Company 
determines that some action need be taken pursuant to the second and/or third 
sentences of this Section 11.1.3, the Company (x) shall provide that such 
action shall apply uniformly to all outstanding Rights, and (y) may suspend 
the exercisability of the Rights until the expiration of the Substitution 
Period in order to seek any authorization of additional shares and/or to 
decide the appropriate form of distribution to be made pursuant to such first 
sentence and to determine the value thereof.  In the event of any such 
suspension, the Company shall issue a public announcement stating that the 
exercisability of the Rights has been temporarily suspended as well as a 
public announcement at such time as the suspension is no longer in effect.  
For purposes of this Section 11.1.3, the value of a Common Share shall be the 
current per share market price (as determined pursuant to Section 11.4) on 
the date of the occurrence of a Trigger Event and the value of any "common 
stock equivalent" shall be deemed to have the same value as the Common Shares 
on such date.  The Board of Directors of the Company may, but shall not be 
required to, establish procedures to allocate the right to receive Common 
Shares upon the exercise of the Rights among holders of Rights pursuant to 
this Section 11.1.3. Actions of the Company pursuant to this Section 11.1.3 
by the vote of a majority of the Board of Directors (including, following a 
Trigger Event, a majority of the Continuing Directions).

          11.2.     DILUTIVE RIGHTS OFFERING.  In case the Company shall fix a
record date for the issuance of rights, options or warrants to all holders of
Preferred Shares entitling them (for a period expiring within 45 calendar days
after such record date) to subscribe for or purchase Preferred Shares (or
securities having the same rights, privileges and preferences as the Preferred
Shares ("EQUIVALENT PREFERRED STOCK")) or securities convertible into Preferred
Shares or 


                                          15
<PAGE>

equivalent preferred stock at a price per Preferred Share or per share of
equivalent preferred stock (or having a conversion or exercise price per share,
if a security convertible into or exercisable for Preferred Shares or equivalent
preferred stock) less than the current per share market price of the Preferred
Shares (as determined pursuant to Section 11.4) 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 Preferred Shares
and shares of equivalent preferred stock outstanding on such record date plus
the number of Preferred Shares and shares of equivalent preferred stock which
the aggregate offering price of the total number of Preferred Shares and/or
shares of equivalent preferred stock to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such current per share market price and the denominator of which shall be the
number of Preferred Shares and shares of equivalent preferred stock outstanding
on such record date plus the number of additional Preferred Shares and/or shares
of equivalent preferred stock to be offered for subscription or purchase (or
into which the convertible securities so to be offered are initially
convertible); PROVIDED, HOWEVER, that in no event shall the consideration to be
paid upon the exercise of one Right be less than the aggregate par value of the
shares of capital stock of the Company issuable upon exercise of one Right.  In
case such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights Agent and the holders of the Rights.  Preferred
Shares and shares of equivalent preferred stock owned by or held for the account
of the Company or any Subsidiary of the Company shall not be deemed outstanding
for the purpose of any such computation.  Such adjustments 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.

          11.3.     DISTRIBUTIONS.  In case the Company shall fix a record date
for the making of a distribution to all holders of the Preferred Shares
(including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation) of
evidences of indebtedness, cash, securities or assets (other than a regular
periodic cash dividend at a rate not in excess of 125% of the rate of the last
regular periodic cash dividend theretofore paid or, in case regular periodic
cash dividends have not theretofore been paid, at a rate not in excess of 50% of
the average net income per share of the Company for the four quarters ended
immediately prior to the payment of such dividend, or a dividend payable in
Preferred Shares (which dividend, for purposes of this Agreement, shall be
subject to the provisions of Section 11.1.1(A))) or convertible securities, or
subscription rights or warrants (excluding those referred to in Section 11.2),
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 per share market
price of the Preferred Shares (as determined pursuant to Section 11.4) 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


                                          16

<PAGE>

cash, assets, securities or evidences of indebtedness so to be distributed or of
such subscription rights or warrants applicable to one Preferred Share and the
denominator of which shall be such current per share market price of the
Preferred Shares (as determined pursuant to Section 11.4); PROVIDED, HOWEVER,
that in no event shall the consideration to be paid upon the exercise of one
Right be less than the aggregate par value of the shares of capital stock of the
Company to be issued upon exercise of one Right.  Such adjustments shall be made
successively whenever such a record date is fixed; and in the event that such
distribution is not so made, the Purchase Price shall again be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.

          11.4.     CURRENT PER SHARE MARKET VALUE.

          11.4.1.   GENERAL.  For the purpose of any computation hereunder, 
the "CURRENT PER SHARE MARKET PRICE" of any security (a "SECURITY" for the 
purpose of this Section 11.4.1) on any date shall be deemed to be the average 
of the daily closing prices per share of such Security for the thirty (30) 
consecutive Trading Days (as such term is hereinafter defined) immediately 
prior to such date; PROVIDED, HOWEVER, that in the event that the current per 
share market price of the Security is determined during any period following 
the announcement by the issuer of such Security of (i) a dividend or 
distribution on such Security payable in shares of such Security or 
securities convertible into such shares or (ii) any subdivision, combination 
or reclassification of such Security, and prior to the expiration of thirty 
(30) Trading Days after the ex-dividend date for such dividend or 
distribution, or the record date for such subdivision, combination or 
reclassification, then, and in each such case, the "current per share market 
price" shall be appropriately adjusted to reflect the current market price 
per share equivalent of such Security.  The closing price for each day shall 
be the last sale price, regular way, or, in case no such sale takes place on 
such day, the average of the closing bid and asked prices, regular way, in 
either case as reported in the principal consolidated transaction reporting 
system with respect to securities listed or admitted to trading on the New 
York Stock Exchange or, if the Security is not listed or admitted to trading 
on the New York Stock Exchange, as reported in the principal consolidated 
transaction reporting system with respect to securities listed on the 
principal national securities exchange on which the Security is listed or 
admitted to trading or, if the Security is not listed or admitted to trading 
on any national securities exchange, the last quoted price or, if not so 
quoted, the average of the high bid and low asked prices in the 
over-the-counter market, as reported by Nasdaq or such other system then in 
use, or, if on any such date the Security is not quoted by any such 
organization, the average of the closing bid and asked prices as furnished by 
a professional market maker making a market in the Security selected by the 
Board of Directors of the Company.  If on any such date no such market maker 
is making a market in the Security, the fair value of the Security on such 
date as determined in good faith by the Board of Directors of the Company 
shall be used.  The term "TRADING DAY" shall mean a day on which the 
principal national securities exchange on which the Security is listed or 
admitted to trading is open for the transaction of business or, if the 
Security is not listed or admitted to trading on any national securities 
exchange, a Business Day.  If the Security is not publicly held or not so 
listed or traded, or if on any such date the Security is not so quoted and no 
such market maker is making a market in the Security, "current per share 
market price" shall mean the fair 


                                          17

<PAGE>

value per share as determined in good faith by the Board of Directors of the
Company or, if at the time of such determination there is an Acquiring Person,
by a majority of the Continuing Directors then in office, or if there are no
Continuing Directors, by a nationally recognized investment banking firm
selected by the Board of Directors, which shall have the duty to make such
determination in a reasonable and objective manner, whose determination shall be
described in a statement filed with the Rights Agent and shall be conclusive for
all purposes.

          11.4.2.   PREFERRED SHARES.  Notwithstanding Section 11.4.1, for the
purpose of any computation hereunder, the "current per share market price" of
the Preferred Shares shall be determined in the same manner as set forth above
in Section 11.4.1 (other than the last sentence thereof).  If the current per
share market price of the Preferred Shares cannot be determined in the manner
described in Section 11.4.1, the "current per share market price" of the
Preferred Shares 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 Shares occurring
after the date of this Agreement) multiplied by the current per share market
price of the Common Shares (as determined pursuant to Section 11.4.1). If
neither the Common Shares nor the Preferred Shares are publicly held or so
listed or traded, (as determined pursuant to Section 11.4.1).  If neither the
Common Shares nor the Preferred Shares are publicly held or so listed or traded,
or if on any such date neither the Common Shares nor the Preferred Shares are so
quoted and no such market maker is making a market in either the Common Shares
or the Preferred Shares, "current per share market price" of the Preferred
Shares shall mean the fair value per share as determined in good faith by the
Board of Directors of the Company, or, if at the time of such determination
there is an Acquiring Person, by a majority of the Continuing Directors then in
office, or if there are no Continuing Directors, by a nationally recognized
investment banking firm selected by the Board of Directors of the Company, which
shall have the duty to make such determination in a reasonable and objective
manner, which determination shall be described in a statement filed with the
Rights Agent and shall be conclusive for all purposes.  For purposes of this
Agreement, the "current per share market price" of one one-hundredth of a
Preferred Share shall be equal to the "current per share market price" of one
Preferred Share divided by 100.

          11.5.     INSIGNIFICANT CHANGES.  No adjustment in the Purchase Price
shall be required unless such adjustment would require an increase or decrease
of at least 1% in the Purchase Price.  Any adjustments which by reason of this
Section 11.5 are not required to be made shall be carried forward and taken into
account in any subsequent adjustment.  All calculations under this Section 11
shall be made to the nearest cent or to the nearest one-hundred thousandth of a
Preferred Share or the nearest one-hundredth of a Common Share or other share or
security, as the case may be.

          11.6.     SHARES OTHER THAN PREFERRED SHARES.  If as a result of an
adjustment made pursuant to Section 11.1, the holder of any Right thereafter
exercised shall become entitled to receive any shares of capital stock of the
Company other than Preferred Shares, thereafter the number of such other shares
so receivable upon exercise of any Right shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to the


                                          18

<PAGE>

provisions with respect to the Preferred Shares contained in Sections 11.1,
11.2, 11.3, 11.5, 11.8, 11.9 and 11.13, and the provisions of Sections 7, 9, 10,
13 and 14 with respect to the Preferred Shares shall apply on like terms to any
such other shares.

          11.7.     RIGHTS ISSUED PRIOR TO ADJUSTMENT.  All Rights originally
issued by the Company subsequent to any adjustment made to the Purchase Price
hereunder shall evidence the right to purchase, at the adjusted Purchase Price,
the number of one one-hundredths of a Preferred Share purchasable from time to
time hereunder upon exercise of the Rights, all subject to further adjustment as
provided herein.

          11.8.     EFFECT OF ADJUSTMENTS.  Unless the Company shall have 
exercised its election as provided in Section 11.9, upon each adjustment of 
the Purchase Price as a result of the calculations made in Sections 11.2 and 
11.3, each Right outstanding immediately prior to the making of such 
adjustment shall thereafter evidence the right to purchase, at the adjusted 
Purchase Price, that number of one one-hundredths of a Preferred Share 
(calculated to the nearest one-hundred thousandth of a Preferred Share) 
obtained by (i) multiplying (x) the number of one one-hundredths of a 
Preferred Share covered by a Right immediately prior to this adjustment by 
(y) the Purchase Price in effect immediately prior to such adjustment of the 
Purchase Price and (ii) dividing the product so obtained by the Purchase 
Price in effect immediately after such adjustment of the Purchase Price.

          11.9.     ADJUSTMENT IN NUMBER OF RIGHTS.  The Company may elect on 
or after the date of any adjustment of the Purchase Price to adjust the 
number of Rights, in substitution for any adjustment in the number of one 
one-hundredths of a Preferred Share issuable upon the exercise of a Right.  
Each of the Rights outstanding after such adjustment of the number of Rights 
shall be exercisable for the number of one one-hundredths of a Preferred 
Share for which a Right was exercisable immediately prior to such adjustment. 
 Each Right held of record prior to such adjustment of the number of Rights 
shall become that number of Rights (calculated to the nearest one-hundredth) 
obtained by dividing the Purchase Price in effect immediately prior to 
adjustment of the Purchase Price by the Purchase Price in effect immediately 
after adjustment of the Purchase Price.  The Company shall make a public 
announcement of its election to adjust the number of Rights, indicating the 
record date for the adjustment, and, if known at the time, the amount of the 
adjustment to be made.  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 (10) days later than the 
date of the public announcement.  If Right Certificates have been issued, 
upon each adjustment of the number of Rights pursuant to this Section 11.9, 
the Company may, as promptly as practicable, cause to be distributed to 
holders of record of Right Certificates on such record date Right 
Certificates evidencing, subject to Section 14, 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


                                          19

<PAGE>

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.

          11.10.    RIGHT CERTIFICATES UNCHANGED.  Irrespective of any
adjustment or change in the Purchase Price or the number of one one-hundredths
of a Preferred Share issuable upon the exercise of the Rights, the Right
Certificates theretofore and thereafter issued may continue to express the
Purchase Price per share and the number of one one-hundredths of a Preferred
Share which were expressed in the initial Right Certificates issued hereunder.

          11.11.    PAR VALUE LIMITATIONS.  Before taking any action that would
cause an adjustment reducing the Purchase Price below one one-hundredth of the
then par value, if any, of the Preferred Shares or other shares of capital stock
issuable upon exercise of the Rights, the Company shall take any corporate
action which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue fully paid and nonassessable Preferred
Shares or other such shares at such adjusted Purchase Price.

          11.12.    DEFERRED ISSUANCE.  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 of that number of Preferred Shares and shares of other capital
stock or securities of the Company, if any, issuable upon such exercise over and
above the Preferred Shares and shares of other capital stock or other
securities, assets or cash of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; PROVIDED,
HOWEVER, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

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

          11.14.    COMPANY NOT TO DIMINISH BENEFITS OF RIGHTS.  The Company
covenants and agrees that after the earlier of the Shares Acquisition Date or
Distribution Date it will not, except as permitted by Section 23, Section 26 or
Section 27, take (or permit any Subsidiary to take) any action if at the time
such action is taken it is reasonably foreseeable that such action


                                          20

<PAGE>

will substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights.

          11.15.    ADJUSTMENT OF RIGHTS ASSOCIATED WITH COMMON SHARES. 
Notwithstanding anything contained in this Agreement to the contrary, in the
event that the Company shall at any time after the date hereof and prior to the
Distribution Date (i) declare or pay any dividend on the outstanding Common
Shares payable in Common Shares, (ii) effect a subdivision or consolidation of
the outstanding Common Shares (by reclassification or otherwise than by the
payment of dividends payable in Common Shares), or (iii) combine the outstanding
Common Shares into a greater or lesser number of Common Shares, then in any such
case, the number of Rights associated with each Common Share then outstanding,
or issued or delivered thereafter but prior to the Distribution Date or in
accordance with Section 22 shall be proportionately adjusted so that the number
of Rights thereafter associated with each Common Share following any such event
shall equal the result obtained by multiplying the number of Rights associated
with each Common Share immediately prior to such event by a fraction, the
numerator of which shall be the total number of Common Shares outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of Common Shares outstanding immediately following the
occurrence of such event.  The adjustments provided for in this Section 11.15
shall be made successively whenever such a dividend is declared or paid or such
a subdivision, combination or consolidation is effected.

          Section 12.       CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF
SHARES.  Whenever an adjustment is made as provided in Sections 11 or 13, the
Company shall (a) promptly prepare a certificate setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) promptly
file with the Rights Agent and with each transfer agent for the Common Shares or
the Preferred Shares a copy of such certificate and (c) mail a brief summary
thereof to each holder of a Right Certificate in accordance with Section 25. 
The Rights Agent shall be fully protected in relying on any such certificate and
on any adjustment therein contained and shall not be deemed to have knowledge of
any such adjustment unless and until it shall have received such certificate.

          Section 13.       CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS
OR EARNING POWER.

          13.1.     CERTAIN TRANSACTIONS.  In the event that, from and after
the first occurrence of a Trigger Event, directly or indirectly, (A) the Company
shall consolidate with, or merge with and into, any other Person and the Company
shall not be the continuing or surviving corporation, (B) any Person shall
consolidate with the Company, or merge with and into the Company and the Company
shall be the continuing or surviving corporation of such merger and, in
connection with such merger, all or part of the Common Shares shall be changed
into or exchanged for stock or other securities of the Company or any other
Person or cash or any other property, or (C) the Company shall sell, exchange,
mortgage or otherwise transfer (or one or more of its Subsidiaries shall sell,
exchange, mortgage or otherwise transfer), in one or more transactions, assets
or earning power aggregating 50% or more of the assets or earning power of the
Company and its Subsidiaries (taken as a whole) to any other Person or Persons
(other than the Company or one or 


                                          21

<PAGE>

more wholly-owned Subsidiaries of the Company or any of the Hilton Interests 
in one or more transactions each of which complies with Section 11.14), then, 
and in each such case, proper provision shall be made so that (i) each holder 
of a Right (other than Rights which have become void pursuant to Section 
11.1.2) shall thereafter have the right to receive, upon the exercise thereof 
at a price per Right equal to the then current Purchase Price multiplied by 
the number of one one-hundredths of a Preferred Share for which a Right was 
exercisable immediately prior to the first occurrence of a Trigger Event (as 
subsequently adjusted pursuant to Sections 11.1.1, 11.2, 11.3, 11.8, 11.9 and 
11.12), in accordance with the terms of this Agreement and in lieu of 
Preferred Shares or Common Shares, such number of validly authorized and 
issued, fully paid, non-assessable and freely tradable Common Shares 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 be equal to the result obtained by (x) multiplying the then current 
Purchase Price by the number of one one-hundredths of a Preferred Share for 
which a Right was exercisable immediately prior to the first occurrence of a 
Trigger Event (as subsequently adjusted pursuant to Sections 11.1.1, 11.2, 
11.3, 11.8, 11.9 and 11.12) and (y) dividing that product by 50% of the then 
current per share market price of the Common Shares of such Principal Party 
(determined pursuant to Section 11.4) on the date of consummation of such 
consolidation, merger, sale or transfer; PROVIDED, that the price per Right 
so payable and the number of Common Shares of such Principal Party so 
receivable upon exercise of a Right shall thereafter be subject to further 
adjustment as appropriate in accordance with Section 11.6 to reflect any 
events covered thereby occurring in respect of the Common Shares 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 consolidation, merger, sale or transfer, all the 
obligations and duties of the Company pursuant to this Agreement; (iii) the 
term "Company" shall thereafter be deemed to refer to such Principal Party; 
and (iv) such Principal Party shall take such steps (including, but not 
limited to, the reservation of a sufficient number of its Common Shares in 
accordance with Section 9) in connection with such consummation as may be 
necessary to assure that the provisions hereof shall thereafter be 
applicable, as nearly as reasonably may be, in relation to its Common Shares 
thereafter deliverable upon the exercise of the Rights; PROVIDED that, upon 
the subsequent occurrence of any consolidation, merger, sale or transfer of 
assets or other extraordinary transaction in respect of such Principal Party, 
each holder of a Right shall thereupon be entitled to receive, upon exercise 
of a Right and payment of the Purchase Price as provided in this Section 
13.1, such cash, shares, rights, warrants and other property which such 
holder would have been entitled to receive had such holder, at the time of 
such transaction, owned the Common Shares of the Principal Party receivable 
upon the exercise of a Right pursuant to this Section 13.1, and such 
Principal Party shall take such steps (including, but not limited to, 
reservation of shares of stock) as may be necessary to permit the subsequent 
exercise of the Rights in accordance with the terms hereof for such cash, 
shares, rights, warrants and other property.  The Company shall not 
consummate any such consolidation, merger, sale or transfer unless prior 
thereto the Company and such Principal Party shall have executed and 
delivered to the Rights Agent a supplemental agreement confirming that the 
requirements of this Section 13.1 and Section 13.2 shall promptly be 
performed in accordance with their terms and that such consolidation, merger, 
sale or transfer of assets shall not result in a default by the Principal 
Party under this Agreement as the same shall have been assumed by the 
Principal Party pursuant to this 


                                          22

<PAGE>

Section 13.1 and Section 13.2 and providing that, as soon as practicable after
executing such agreement pursuant to this Section 13, the Principal Party, at
its own expense, shall

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

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

          (3)       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 

          (4)       obtain waivers of any rights of first refusal or preemptive
rights in respect of the Common Shares of the Principal Party subject to
purchase upon exercise of outstanding RIGHTS.

          In case the Principal Party has provision in any of its authorized
securities or in its certificate of incorporation or by-laws or other instrument
governing its corporate affairs, which provision would have the effect of (i)
causing such Principal Party to issue (other than to holders of Rights pursuant
to this Section 13), in connection with, or as a consequence of, the
consummation of a transaction referred to in this Section 13, Common Shares or
common stock equivalents of such Principal Party at less than the then current
market price per share thereof (determined pursuant to Section 11.4) or
securities exercisable for, or convertible into, Common Shares or common stock
equivalents 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, taxes or similar provision in connection with the
issuance of the Common Shares of such Principal Party pursuant to the provision
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 


                                          23

<PAGE>

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.

          The Company covenants and agrees that it shall not, at any time after
the Trigger Event, enter into any transaction of the type described in clauses
(A) through (C) of this Section 13.1 if (i) at the time of or immediately after
such consolidation, merger, sale, transfer or other transaction there are any
rights, warrants or other instruments or securities outstanding or agreements in
effect which would substantially diminish or otherwise eliminate the benefits
intended to be afforded by the Rights, (ii) prior to, simultaneously with or
immediately after such consolidation, merger, sale, transfer or other
transaction, the stockholders of the Person who constitutes, or would
constitute, the Principal Party for purposes of Section 13.2 shall have received
a distribution of Rights previously owned by such Person or any of its
Affiliates or Associates or (iii) the form or nature of organization of the
Principal Party would preclude or limit the exercisability of the Rights.  The
provisions of this Section 13 shall similarly apply to successive transactions
of the type described in clauses (A) through (C) of this Section 13.1.

          13.2.     PRINCIPAL PARTY.  "Principal Party" shall mean: 

                    (i)     in the case of any transaction described in (A) or
(B) of the first sentence of Section 13.1:  (i) the Person that is the issuer of
the securities into which the Common Shares are converted in such merger or
consolidation, or, if there is more than one such issuer, the issuer the Common
Shares of which have the greatest aggregate market value of shares outstanding,
or (ii) if no securities are so issued, (x) the Person that is the other party
to the merger, if such Person survives said merger, or, if there is more than
one such Person, the Person the Common Shares of which have the greatest
aggregate market value of shares outstanding or (y) if the Person that is the
other party to the merger does not survive the merger, the Person that does
survive the merger (including the Company if it survives) or (z) the Person
resulting from the consolidation; and

                    (ii)    in the case of any transaction described in (C) of
the first sentence in Section 13.1, the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to such
transaction or transactions, or, if each Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power so transferred or if the Person receiving the greatest portion of the
assets or earning power cannot be determined, whichever of such Persons is the
issuer of Common Shares having the greatest aggregate market value of shares
outstanding; PROVIDED, HOWEVER, that in any such case described in the foregoing
clause (A) or (B) of this Section 13.2, if the Common Shares of such Person are
not at such time or have not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, then (1) if such Person
is a direct or indirect Subsidiary of another Person the Common Shares of which
are and have 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 Shares 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 Common Shares having the greatest aggregate market value of
shares outstanding, or (3) if such Person is owned, directly or indirectly, by a
joint venture formed by two or more Persons that are not owned, 


                                          24

<PAGE>

directly or indirectly, by the same Person, the rules set forth in clauses (1)
and (2) above shall apply to each of the owners having an interest in the
venture as if the Person owned by the joint venture was a Subsidiary of both or
all of such joint venturers, and the Principal Party in each such case shall
bear the obligations set forth in this Section 13 in the same ratio as its
interest in such Person bears to the total of such interests.

          13.3.     APPROVED ACQUISITIONS.  Notwithstanding anything contained
herein to the contrary, in the event of any merger or other acquisition
transaction involving the Company pursuant to a merger or other acquisition
agreement between the Company and any Person (or one or more of such Person's
Affiliates or Associates) which agreement has been approved by the Board of
Directors of the Company prior to any Person becoming an Acquiring Person, this
Agreement and the rights of holders of Rights hereunder shall be terminated in
accordance with Section 7.1.

          Section 14.       FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

          14.1.     CASH IN LIEU OF FRACTIONAL RIGHTS.  The Company shall not
be required to issue fractions of Rights or to distribute Right Certificates
which evidence fractional Rights (except prior to the Distribution Date in
accordance with Section 11.15).  In lieu of such fractional Rights, there shall
be paid to the registered holders of the Right Certificates with regard to which
such fractional Rights would otherwise be issuable an amount in cash equal to
the same fraction of the current market value of a whole Right.  For the
purposes of this Section 14.1, the current market value of a whole Right shall
be the closing price of the Rights for the Trading Day immediately prior to the
date on which such fractional Rights would have been otherwise issuable.  The
closing price for any day shall be the last sale price, regular way, or, in case
no such sale takes place on such day, the average of the closing bid and asked
prices, regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the Rights are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Rights are listed or
admitted to trading or, if the Rights are not listed or admitted to trading on
any national securities exchange, the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported by Nasdaq or such other system then in use or, if on any such date
the Rights are not quoted by any such organization, the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Rights selected by the Board of Directors of the Company.  If on any such
date no such market maker is making a market in the Rights, the current market
value of the Rights on such date shall be the fair value of the Rights as
determined in good faith by the Board of Directors of the Company, or, if at the
time of such determination there is an Acquiring Person, by a majority of the
Continuing Directors then in office, or if there are no Continuing Directors, by
a nationally recognized investment banking firm selected by the Board of
Directors of the Company, which shall have the duty to make such determination
in a reasonable and objective manner, which determination 


                                          25

<PAGE>

shall be described in a statement filed with the Rights Agent and shall be
conclusive for all purposes.

          14.2.     CASH IN LIEU OF FRACTIONAL PREFERRED SHARES.  The Company
shall not be required to issue fractions of Preferred Shares (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share) upon exercise or exchange of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-hundredth of a Preferred Share).  Interests in
fractions of Preferred Shares in integral multiples of one one-hundredth of a
Preferred Share may, at the election of the Company, be evidenced by depositary
receipts, pursuant to an appropriate agreement between the Company and a
depositary selected by it; PROVIDED, that such agreement shall provide that the
holders of such depositary receipts shall have all the rights, privileges and
preferences to which they are entitled as beneficial owners of the Preferred
Shares represented by such depositary receipts.  In lieu of fractional Preferred
Shares that are not integral multiples of one one-hundredth of a Preferred
Share, the Company shall pay to the registered holders of Right Certificates at
the time such Rights are exercised or exchanged as herein provided an amount in
cash equal to the same fraction of the current per share market price of one
Preferred Share (as determined in accordance with Section 14.1) for the Trading
Day immediately prior to the date of such exercise or exchange.

          14.3.     CASH IN LIEU OF FRACTIONAL COMMON SHARES.  The Company
shall not be required to issue fractions of Common Shares or to distribute
certificates which evidence fractional Common Shares upon the exercise or
exchange of Rights.  In lieu of such fractional Common Shares, the Company shall
pay to the registered holders of the Right Certificates with regard to which
such fractional Common Shares would otherwise be issuable an amount in cash
equal to the same fraction of the current market value of a whole Common Share
(as determined in accordance with Section 14.1) for the Trading Day immediately
prior to the date of such exercise or exchange.

          14.4.     WAIVER OF RIGHT TO RECEIVE FRACTIONAL RIGHTS OR SHARES. 
The holder of a Right by the acceptance of the Rights expressly waives his right
to receive any fractional Rights or any fractional shares upon exercise or
exchange of a Right, except as permitted by this Section 14.

          Section 15.       RIGHTS OF ACTION.  All rights of action in respect
of this Agreement, except the rights of action given to the Rights Agent under
Section 18, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), 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 Shares), may, in his own behalf and for his own
benefit, enforce this Agreement, and may institute and maintain any suit, action
or proceeding against the Company to enforce this Agreement, or otherwise
enforce or 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 



                                          26

<PAGE>

specifically acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this Agreement and shall be entitled to specific
performance of the obligations under, and injunctive relief against actual or
threatened violations of, the obligations of any Person (including, without
limitation, the Company) subject to this Agreement.

          Section 16.       AGREEMENT OF RIGHT HOLDERS.  Every holder of a Right
by accepting the same consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

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

                    (b)     as of and after the Distribution Date, the Right
     Certificates are 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
     with all required certifications completed; and

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

          Section 17.       RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. 
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 24), or to receive dividends or
subscription rights, or otherwise, until the Right or Rights evidenced by such
Right Certificate shall have been exercised in accordance with the provisions
hereof.

          Section 18.       CONCERNING THE RIGHTS AGENT.  The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder in accordance with a fee schedule to be mutually agreed upon and, from
time to time, on demand of the Rights Agent, its reasonable expenses and counsel
fees and other disbursements incurred in the administration and execution of
this Agreement and the exercise and performance of its duties hereunder.  The
Company also agrees to indemnify the Rights Agent for, and to hold it harmless
against, any loss, liability, or expense, incurred without negligence, bad faith
or willful misconduct on the part of the Rights Agent, for anything done or
omitted by the Rights Agent in 


                                          27
<PAGE>

connection with the acceptance and administration of this Agreement, 
including the costs and expenses of defending against any claim of liability 
arising therefrom, directly or indirectly.

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

          Section 19.       MERGER OR CONSOLIDATION OR CHANGE OF NAME OF 
RIGHTS AGENT.  Any corporation or limited liability company into which the 
Rights Agent or any successor Rights Agent may be merged or with which it may 
be consolidated, or any corporation or limited liability company resulting 
from any merger or consolidation to which the Rights Agent or any successor 
Rights Agent shall be a party, or any corporation or limited liability 
company 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 or limited liability company would be eligible for 
appointment as a successor Rights Agent under the provisions of Section 21.  
In case at the time such successor Rights Agent shall succeed to the agency 
created by this Agreement, any of the Right Certificates shall have been 
countersigned but not delivered, any such successor Rights Agent may adopt 
the countersignature of 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.

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

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

          20.1.     LEGAL COUNSEL.  The Rights Agent may consult with legal 
counsel selected by it (who may be legal counsel for the Company), and the 
opinion of such counsel shall be full 


                                      28

<PAGE>

and complete authorization and protection to the Rights Agent as to any 
action taken or omitted by it in good faith and in accordance with such 
opinion.

          20.2.     CERTIFICATES AS TO FACTS OR MATTERS.  Whenever in the
performance of its duties under this Agreement the Rights Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the
Company prior to taking or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by a certificate signed by
any one of the Chairman of the Board of Directors, the Chief Executive Officer,
the President, the Chief Financial Officer, any Vice President, the Treasurer,
the Secretary or any Assistant Treasurer or 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 Agreement in reliance upon such certificate.

          20.3.     STANDARD OF CARE.  The Rights Agent shall be liable
hereunder only for its own negligence, bad faith or willful misconduct.

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

          20.5.     NO RESPONSIBILITY AS TO CERTAIN MATTERS.  The Rights Agent
shall not be under any responsibility in respect of the validity of this
Agreement or the execution and delivery hereof (except the due execution hereof
by the Rights Agent) or in respect of the validity or execution of any Right
Certificate (except its countersignature thereof); nor shall it be responsible
for any breach by the Company of any covenant or condition contained in this
Agreement or in any Right Certificate; nor shall it be responsible for any
change in the exercisability of the Rights (including the Rights becoming void
pursuant to Section 11.1.2) or any adjustment required under the provisions of
Sections 3, 11, 13, 23 or 27 or responsible for the manner, method or amount of
any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights
evidenced by Right Certificates after actual notice of any such change or
adjustment); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any
Preferred Shares or other securities to be issued pursuant to this Agreement or
any Right Certificate or as to whether any Preferred Shares will, when so
issued, be validly authorized and issued, fully paid and nonassessable.

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

          20.7.     AUTHORIZED COMPANY OFFICERS.  The Rights Agent is hereby
authorized and directed to accept instructions with respect to the performance
of its duties hereunder from any one of the Chairman of the Board of Directors,
the Chief Executive Officer, the President, the Chief Financial Officer, any
Vice President, the Treasurer, the Secretary or any Assistant Treasurer or
Assistant Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties under this Agreement, 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 or for any delay in acting
while waiting for these instructions.  Any application by the Rights Agent for
written instructions from the Company may, at the option of the Rights Agent,
set forth in writing any action proposed to be taken or omitted by the Rights
Agent with respect to its duties or obligations under this Agreement and the
date on and/or after which such action shall be taken or such omission shall be
effective.  The Rights Agent shall not be liable to the Company 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 therein (which
date shall not be less than three business days after the date any such officer
actually receives such application, unless any such officer shall have consented
in writing to an earlier date) unless, prior to taking of any such action (or
the effective date in the case of omission), the Rights Agent shall have
received written instructions in response to such application specifying the
action to be taken or omitted.

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

          20.9.     RELIANCE ON ATTORNEYS AND AGENTS.  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, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss
to the Company resulting from any such act, omission, default, neglect or
misconduct, PROVIDED that reasonable care was exercised in the selection and
continued employment thereof.

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

          20.11.    RIGHTS HOLDERS LIST.  At any time and from time to time
after the Distribution Date, upon the request of the Company, the Rights Agent
shall promptly deliver to 


                                      30

<PAGE>

the Company a list, as of the most recent practicable date (or as of such 
earlier date as may be specified by the Company), of the holders of record of 
Rights.

          Section 21.       CHANGE OF RIGHTS AGENT.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Company and to
each transfer agent of the Common Shares and/or Preferred Shares, as applicable,
by registered or certified mail.  Following the Distribution Date, the Company
shall promptly notify the holders of the Right Certificates by first-class mail
of any such resignation.  The Company may remove the Rights Agent or any
successor Rights Agent upon thirty (30) days' notice in writing, mailed to the
Rights Agent or successor Rights Agent, as the case may be, and to each transfer
agent of the Common Shares and/or Preferred Shares, as applicable, 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 resigning, removed, or incapacitated Rights Agent shall
remit to the Company, or to any successor Rights Agent designated by the
Company, all books, records, funds, certificates or other documents or
instruments of any kind then in its possession which were acquired by such
resigning, removed or incapacitated Rights Agent in connection with its services
as Rights Agent hereunder, and shall thereafter be discharged from all duties
and obligations hereunder.  Following notice of such removal, resignation or
incapacity, the Company shall appoint a successor to such Rights Agent.  If the
Company shall fail to make such appointment within a period of thirty (30) days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Right Certificate (who shall, with such notice, submit his
Right Certificate for inspection by the Company), then the registered holder of
any Right Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent.  Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be a corporation organized
and doing business under the laws of the United States or of the State of New
York or the State of California (or any other state of the United States so long
as such corporation is authorized to do business as a banking institution in the
State of New York or California) in good standing, having an office in the State
of New York or the State of California, which is authorized under such laws to
exercise stock transfer or corporate trust powers and is subject to supervision
or examination by Federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $10
million.  After appointment, the successor Rights Agent shall be vested with the
samepowers, 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 Shares
and/or Preferred Shares, as applicable, and, following the Distribution Date,
mail a notice thereof in writing to the registered holders of the Right
Certificates. Failure to give any notice provided for in this Section 21,
however, or any 


                                      31

<PAGE>

defect therein, shall not affect the legality or validity of the resignation 
or removal of the Rights Agent or the appointment of the successor Rights 
Agent, as the case may be.

          Section 22.       ISSUANCE OF NEW RIGHT CERTIFICATES.  Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares or
other securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Agreement.  In addition, in connection
with the issuance or sale of Common Shares following the Distribution Date and
prior to the Expiration Date, the Company (a) shall, with respect to Common
Shares so issued or sold pursuant to the exercise of stock options or under any
employee plan or arrangement, granted or awarded as of the Distribution Date, or
upon exercise, conversion or exchange of securities hereinafter issued by the
Company, and (b) may, in any other case, if deemed necessary or appropriate by
the Board of Directors of the Company, 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, (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 and (iii) at the
time of a determination by the Board of Directors to cause the Company to issue
a Right Certificate under clause (b) above, there must be Continuing Directors
then in office and any such determination shall require the approval of at least
a majority of such Continuing Directors.

          Section 23.       REDEMPTION.

          Section 23.1.     RIGHT TO REDEEM.  The Board of Directors of the
Company may, at its option, at any time prior to the close of business on the
tenth day following the Shares Acquisition Date, redeem all but not less than
all of the then outstanding Rights at a redemption price of $.001 per Right,
appropriately adjusted to reflect any stock split, stock dividend,
recapitalization or similar transaction occurring after the date hereof (such
redemption price being hereinafter referred to as the "REDEMPTION PRICE"), and
the Company may, at its option, pay the Redemption Price in Common Shares (based
on the "current per share market price," determined pursuant to Section 11.4, of
the Common Shares at the time of redemption), cash or any other form of
consideration deemed appropriate by the Board of Directors; PROVIDED, HOWEVER,
that if the Board of Directors of the Company authorizes redemption of the
Rights after the time a Person becomes an Acquiring Person, then there must be
Continuing Directors then in office and such authorization shall require the
approval of at least a majority of such Continuing Directors.  The preceding
sentence notwithstanding, prior to the expiration of the period during which the
Rights may be redeemed as specified therein (or such longer period as the Board
of Directors of the Company may select pursuant to this sentence), the Board of
Directors of the Company may extend, one or more times, the period during which
the Rights may be redeemed beyond the close of business on the tenth day
following the Shares Acquisition Date; PROVIDED, 


                                      32

<PAGE>

HOWEVER, that there must be Continuing Directors then in office and any such 
extension shall require the approval of at least a majority of such 
Continuing Directors.  The redemption of the Rights by the Board of Directors 
may be made effective at such time, on such basis and subject to such 
conditions as the Board of Directors in its sole discretion may establish.  
Notwithstanding anything contained in this Agreement to the contrary, the 
Rights shall not be exercisable following a transaction or event described in 
Section 11.1.2 prior to the expiration or termination of the Company's right 
of redemption hereunder.

          Section 23.2.     REDEMPTION PROCEDURES.  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 for
each Right so held.  The Company shall promptly give public notice of such
redemption; PROVIDED, HOWEVER, that the failure to give, or any defect in, any
such notice shall not affect the validity of such redemption.  The Company shall
promptly give, or cause the Rights Agent to give, notice of such redemption to
the holders of the then outstanding Rights by mailing such notice to all such
holders at their last addresses as they appear upon the registry books of the
Rights Agent or, prior to the Distribution Date, on the registry books of the
transfer agent for the Common Shares.  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.  Neither the Company nor any of
its Affiliates or Associates (other than Hilton Interests) may redeem, acquire
or purchase for value any Rights at any time in any manner other than that
specifically set forth in this Section 23 or in Section 27, and other than in
connection with the purchase, acquisition or redemption of Common Shares prior
to the Distribution Date.

          Section 24.       NOTICE OF CERTAIN EVENTS.  In case the Company shall
propose at any time after the earlier of the Shares Acquisition Date and the
Distribution Date (a) to pay any dividend payable in stock of any class to the
holders of Preferred Shares or to make any other distribution to the holders of
Preferred Shares (other than a regular periodic cash dividend at a rate not in
excess of 125% of the rate of the last regular periodic cash dividend
theretofore paid or, in case regular periodic cash dividends have not
theretofore been paid, at a rate not in excess of 50% of the average net income
per share of the Company for the four quarters ended immediately prior to the
payment of such dividends, or a stock dividend on, or a subdivision, combination
or reclassification of the Common Shares), or (b) to offer to the holders of
Preferred Shares rights or warrants to subscribe for or to purchase any
additional Preferred Shares or shares of stock of any class or any other
securities, rights or options, or (c) to effect any reclassification of its
Preferred Shares (other than a reclassification involving only the subdivision
of outstanding Preferred Shares), or (d) to effect any consolidation or merger
into or with, or to effect any sale or other transfer (or to permit one or more
of its Subsidiaries to effect any sale or other transfer), in one or more
transactions, of 50% or more of the assets or earning power of the Company and
its Subsidiaries (taken as a whole) to, any other Person (other than pursuant to
a merger or other acquisition agreement of the type described in Section
1.3(ii)(A)(z)), or (e) to effect the 


                                      33

<PAGE>

liquidation, dissolution or winding up of the Company, or (f) to declare or 
pay any dividend on the Common Shares payable in Common Shares or to effect a 
subdivision, combination or consolidation of the Common Shares (by 
reclassification or otherwise than by payment of dividends in Common Shares), 
then, in each such case, the Company shall give to the Rights Agent and to 
each holder of a Right Certificate, in accordance with Section 25, a notice 
of such proposed action, which shall specify the record date for the purposes 
of such stock dividend, distribution of rights or warrants, or the date on 
which such reclassification, consolidation, merger, sale, transfer, 
liquidation, dissolution, or winding up is to take place and the date of 
participation therein by the holders of the Preferred Shares and/or Common 
Shares, if any such date is to be fixed, and such notice shall be so given in 
the case of any action covered by clause (a) or (b) above at least ten (10) 
days prior to the record date for determining holders of the Preferred Shares 
for purposes of such action, and in the case of any such other action, at 
least ten (10) days prior to the date of the taking of such proposed action 
or the date of participation therein by the holders of the Preferred Shares 
and/or Common Shares, whichever shall be the earlier.

          In case any event set forth in Section 11.1.2 or Section 13 shall
occur, then, in any such case, (i) the Company shall as soon as practicable
thereafter give to the Rights Agent and to each holder of a Right Certificate,
in accordance with Section 25, a notice of the occurrence of such event, which
notice shall describe the event and the consequences of the event to holders of
Rights under Section 11.1.2 and Section 13, and (ii) all references in this
Section 24 to Preferred Shares shall be deemed thereafter to refer to Common
Shares and/or, if appropriate, other securities.

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

          Section 25.       NOTICES.  Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by

                    Attention:  Martha O. Mijango

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Right Certificate (or, prior to
the Distribution Date, to the holder of any certificate representing Common
Shares) shall be sufficiently given or made if sent by first-class mail, postage
prepaid, addressed to such holder at the address of such holder as shown on the
registry books of the Company.

          Section 26.       SUPPLEMENTS AND AMENDMENTS.  For so long as the
Rights are then redeemable, the Company may in its sole and absolute discretion,
and the Rights Agent shall, if the Company so directs, supplement or amend any
provision of this Agreement in any respect without the approval of any holders
of Rights or Common Shares.  From and after the time that the Rights are no
longer redeemable, the Company may, and the Rights Agent shall, if the Company
so directs, from time to time supplement or amend this Agreement without the
approval of any holders of Rights (i) to cure any ambiguity or to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, (ii) to shorten or lengthen any time period
hereunder (which shortening or lengthening, after the time a Person becomes an
Acquiring Person, shall be effective only if there are Continuing Directors and
shall require the approval of at least a majority of such Continuing Directors)
or (iii) to make any other changes or provisions in regard to matters or
questions arising hereunder which the Company may deem necessary or desirable,
including but not limited to extending the Final Expiration Date; PROVIDED,
HOWEVER, that no such supplement or amendment shall adversely affect the
interests of the holders of Rights as such (other than an Acquiring Person or an
Affiliate or Associate of an Acquiring Person), and no such supplement or
amendment may cause the Rights again to become redeemable or cause this
Agreement again to become amendable other than in accordance with this sentence;
PROVIDED FURTHER, that the right of the Board of Directors to extend the
Distribution Date or the Redemption Date shall not require any amendment or
supplement hereunder.  Upon the delivery of a certificate from an appropriate
officer of the Company which states that the proposed supplement or amendment is
in compliance with the terms of this Section 26, the Rights Agent shall execute
such supplement or amendment.  Without limiting the foregoing, at any time prior
to such time as any Person becomes an Acquiring Person, the Company and the
Rights Agent may amend this Agreement to lower the thresholds set forth in
Sections 1.1 and 3.1 to not less than the greater of (i) any percentage greater
than the largest percentage of the outstanding Common Shares then known by the
Company to be beneficially owned by any Person (other than an Exempt Person) and
(ii) 10%.

          Section 27.       EXCHANGE.

          27.1.     EXCHANGE OF COMMON SHARES FOR RIGHTS.  The Board of
Directors of the Company may, at its option, at any time after the occurrence of
a Trigger Event, exchange 


                                      35

<PAGE>

Common Shares for all or part of the then outstanding and exercisable Rights 
(which shall not include Rights that have become void pursuant to the 
provisions of Section 11.1.2) by exchanging at an exchange ratio of that 
number of Common Shares having an aggregate value equal to the Spread (with 
such value being based on the current per share market price (as determined 
pursuant to Section 11.4) on the date of the occurrence of a Trigger Event) 
per Right, appropriately adjusted to reflect any stock split, stock dividend 
or similar transaction occurring after the date hereof (such amount per Right 
being hereinafter referred to as the "EXCHANGE CONSIDERATION"). 
Notwithstanding the foregoing, the Board of Directors shall not be empowered 
to effect such exchange at any time after any Acquiring Person shall have 
become the Beneficial Owner of 50% or more of the Common Shares then 
outstanding.  From and after the occurrence of an event specified in Section 
13.1, any Rights that theretofore have not been exchanged pursuant to this 
Section 27.1 shall thereafter be exercisable only in accordance with Section 
13 and may not be exchanged pursuant to this Section 27.1.  The exchange of 
the Rights by the Board of Directors may be made effective at such time, on 
such basis and with such conditions as the Board of Directors in its sole 
discretion may establish.

          27.2.     EXCHANGE PROCEDURES.  Immediately upon the action of the
Board of Directors of the Company ordering the exchange for any Rights pursuant
to Section 27.1 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 the Exchange Consideration.  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
shall state the method by which the exchange of the Common Shares 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 the Rights that have become void pursuant to
the provisions of Section 11.1.2) held by each holder of Rights.

          27.3.     INSUFFICIENT SHARES.  The Company may at its option
substitute, and, in the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit an exchange of
Rights for Common Shares as contemplated in accordance with this Section 27, the
Company shall substitute to the extent of such insufficiency, for each Common
Share that would otherwise be issuable upon exchange of a Right, a number of
Preferred Shares or fraction thereof (or equivalent preferred stock, as such
term is defined in Section 11.2) such that the current per share market price
(determined pursuant to Section 11.4) of one Preferred Share (or equivalent
preferred share) multiplied by such number or fraction is equal to the current
per share market price of one Common Share (determined pursuant to Section 11.4)
as of the date of such exchange.

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

          Section 29.       BENEFITS OF THIS AGREEMENT.  Nothing in this
Agreement shall be construed to give to any Person or corporation other than the
Company, the Rights Agent and the registered holders of the Right Certificates
(and, prior to the Distribution Date, the Common Shares) any legal or equitable
right, remedy or claim under this Agreement; but this Agreement shall be for the
sole and exclusive benefit of the Company, the Rights Agent and the registered
holders of the Right Certificates (and, prior to the Distribution Date, the
Common Shares).

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

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

          Section 32.       GOVERNING LAW.  This Agreement and each Right
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts to
be made and performed entirely within such State.

          Section 33.       COUNTERPARTS.  This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

          Hilton Hotels Corporation, a corporation organized and existing 
under the General Corporation Law of the State of Delaware (hereinafter 
called the "CORPORATION"), hereby certifies that the following resolution was 
adopted by the Board of Directors of the Corporation as required by Section 
151 of the General Corporation Law at a meeting duly called and held on July 
9, 1998.

          RESOLVED, that pursuant to the authority granted to and vested in 
the Board of Directors of this Corporation (hereinafter called the "BOARD OF 
DIRECTORS" or the "BOARD") in accordance with the provisions of the 
Certificate of Incorporation of this Corporation, the Board of Directors 
hereby creates a series of Preferred Stock, par value $1.00 per share (the 
"PREFERRED STOCK"), of the Corporation and hereby states the designation and 
number of shares, and fixes the relative rights, powers and preferences, and 
qualifications, limitations and restrictions thereof as follows:

          Section 1.     DESIGNATION AND AMOUNT.  The shares of such series 
shall be designated as "Series A Junior Participating Preferred Stock" (the 
"SERIES A PREFERRED STOCK") and the number of shares constituting the Series 
A Preferred Stock shall be 3,000,000.  Such number of shares may be increased 
or decreased by resolution of the Board of Directors; PROVIDED, that no 
decrease shall reduce the number of shares of Series A Preferred Stock to a 
number less than the number of shares then outstanding plus the number of 
shares reserved for issuance upon the exercise of outstanding options, rights 
or warrants or upon the conversion of any outstanding securities issued by 
the Corporation convertible into Series A Preferred Stock.

          Section 2.     DIVIDENDS AND DISTRIBUTIONS.

          (A)  Subject to the prior and superior rights of the holders of
     any shares of any class or series of stock of this Corporation ranking
     prior and superior to the Series A 


                                      A-1

<PAGE>

     Preferred Stock with respect to dividends, the holders of shares of 
     Series A Preferred Stock, in preference to the holders of Common Stock, 
     par value $2.50 per share (the "COMMON STOCK"), of the Corporation, and 
     of any other stock ranking junior to the Series A Preferred Stock, shall 
     be entitled to receive, when, as and if declared by the Board of 
     Directors out of funds legally available for the purpose, quarterly 
     dividends payable in cash on the first day of March, June, September and 
     December in each year (each such date being referred to herein as a 
     "QUARTERLY DIVIDEND PAYMENT DATE"), commencing on the first Quarterly 
     Dividend Payment Date after the first issuance of a share or fraction of 
     a share of Series A Preferred Stock, in an amount per share (rounded to 
     the nearest cent) equal to the greater of (a) $1.00 or (b) subject to 
     the provision 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 kind) of all non-cash dividends 
     or other distributions, other than a dividend payable in shares of 
     Common Stock or a subdivision of the outstanding shares of Common Stock 
     (by reclassification or otherwise), declared on the Common Stock since 
     the immediately preceding Quarterly Dividend Payment Date or, with 
     respect to the first Quarterly Dividend Payment Date, since the first 
     issuance of any share or fraction of a share of Series A Preferred 
     Stock. In the event the Corporation shall at any time declare or pay any 
     dividend on the Common Stock payable in shares of Common Stock, or 
     effect a subdivision, combination or consolidation of the outstanding 
     shares of Common Stock (by reclassification or otherwise than by payment 
     of a dividend in shares of Common Stock) into a greater or lesser number 
     of shares of Common Stock, then in each such case the amount to which 
     holders of shares of Series A Preferred Stock were entitled immediately 
     prior to such event under 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)  The Corporation shall declare a dividend or distribution on
     the Series A Preferred Stock as provided in paragraph (A) of this Section 2
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided
     that, in the event no dividend or distribution shall have been declared on
     the Common Stock during the period between any Quarterly Dividend Payment
     Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
     $1.00 per share on the Series A Preferred Stock shall nevertheless be
     payable on such subsequent Quarterly Dividend Payment Date.

          (C)  Dividends shall begin to accrue and be cumulative on
     outstanding shares of Series A Preferred Stock from the Quarterly Dividend
     Payment Date next preceding the date of issue of such shares, 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 


                                      A-2

<PAGE>

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

          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 declare
     or pay any dividend on the Common Stock payable in shares of Common Stock,
     or effect a subdivision, combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

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

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

          Section 4.     CERTAIN RESTRICTIONS.

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


                                      A-3

<PAGE>

     shares of Series A Preferred Stock outstanding shall have been paid in 
     full, the Corporation shall not:

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

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

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

               (iv) redeem or 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.

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

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

<PAGE>

          Section 6.     LIQUIDATION, DISSOLUTION OR WINDING UP.  (A) Upon 
any liquidation, dissolution or winding up of the Corporation, voluntary or 
otherwise no distribution shall be made (1) to the holders of shares of stock 
ranking junior (either as to dividends or upon liquidation, dissolution or 
winding up) to the Series A Preferred Stock unless, prior thereto, the 
holders of shares of Series A Preferred Stock shall have received an amount 
per share (the "Series A Liquidation Preference") equal to $100 per share, 
plus an amount equal to accrued and unpaid dividends and distributions 
thereon, whether or not declared, to the date of such payment, provided that 
the holders of shares of Series A Preferred Stock shall be entitled to 
receive an aggregate amount per share, subject to the provision for 
adjustment hereinafter set forth, equal to 100 times the aggregate amount to 
be distributed per share to holders of shares of Common Stock, or (2) to the 
holders of 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 distributions made ratably on the Series A Preferred Stock and 
all such parity stock in proportion to the total amounts to which the holders 
of all such shares are entitled upon such liquidation, dissolution or winding 
up.  In the event the Corporation shall at any time declare or pay any 
dividend on the Common Stock payable in shares of Common Stock, or effect a 
subdivision, combination or consolidation of the outstanding shares of Common 
Stock (by reclassification or otherwise than by payment of a dividend in 
shares of Common Stock) into a greater or lesser number of shares of Common 
Stock, then in each such case the aggregate amount to which holders of shares 
of Series A Preferred Stock were entitled immediately prior to such event 
under the proviso in clause (1) of the preceding sentence shall be adjusted 
by multiplying such amount by a fraction the numerator of which is the number 
of shares of Common Stock outstanding immediately after such event and the 
denominator of which is the number of shares of Common Stock that are 
outstanding immediately prior to such event.

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

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

          Section 7.     CONSOLIDATION, MERGER, ETC.  In case the Corporation 
shall enter into any consolidation, merger, combination or other transaction 
in which the shares of Common Stock are exchanged for or changed into other 
stock or securities, cash and/or any other property, then in any such case 
each share of Series A Preferred Stock shall at the same time be similarly 
exchanged or changed into an amount per share, subject to the provision for 
adjustment hereinafter set forth, equal to 100 times the aggregate amount of 
stock, securities, cash and/or 


                                      A-5

<PAGE>

any other property (payable in kind), as the case may be, into which or for 
which each share of Common Stock is changed or exchanged. In the event the 
Corporation shall at any time declare or pay any dividend on the Common Stock 
payable in shares of Common Stock, or effect a subdivision, combination or 
consolidation of the outstanding shares of Common Stock (by reclassification 
or otherwise than by payment of a dividend in shares of Common Stock) into a 
greater or lesser number of shares of Common Stock, then in each such case 
the amount set forth in the preceding sentence with respect to the exchange 
or change of shares of Series A Preferred Stock shall be adjusted by 
multiplying such amount by a fraction, the numerator of which is the number 
of shares of Common Stock outstanding immediately after such event and the 
denominator of which is the number of shares of Common Stock that were 
outstanding immediately prior to such event.

          Section 8.     NO REDEMPTION.  The shares of Series A Preferred 
Stock shall not be redeemable by the Company.

          Section 9.     RANK.  The Series A Preferred Stock shall rank, with 
respect to the payment of dividends and the distribution of assets upon 
liquidation, dissolution or winding up, junior to all series of any other 
class of the Corporation's Preferred Stock, except to the extent that any 
such other series specifically provides that it shall rank on a parity with 
or junior to the Series A Preferred Stock.

          Section 10.    AMENDMENT.  At any time any shares of Series A 
Preferred Stock are outstanding, 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 at least two-thirds of the outstanding shares of Series A 
Preferred Stock, voting separately as a single class.

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

business on the tenth day after the Shares Acquisition Date or (ii) exchange 
Common Shares for the Rights evidenced by this Certificate, in whole or in 
part.  The period during which redemption of the Rights is permitted may be 
extended by the Board of Directors of the Company, but such an extension 
shall require the concurrence of a majority of the Continuing Directors.  
Under certain circumstances set forth in the Rights Agreement, the decision 
to redeem shall require the concurrence of a majority of the Continuing 
Directors.

          No fractional Preferred Shares will be issued upon the exercise of 
any Right or Rights evidenced hereby (other than fractions of Preferred 
Shares which are integral multiples of one one-hundredth of a Preferred 
Share, which may, at the election of the Company, be evidenced by depository 
receipts), but in lieu thereof a cash payment will be made, as provided in 
the Agreement.

          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 the 
Preferred Shares 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 
Agreement or herein be construed to confer upon the holder hereof, as such, 
any of the rights of a stockholder of the Company or any right to vote for 
the election of directors or upon any matter submitted to stockholders at any 
meeting thereof, or to give or withhold consent to any corporate action, or 
to receive notice of meetings or other actions affecting stockholders (except 
as provided in the Agreement), or to receive dividends or subscription 
rights, or otherwise, until the Right or Rights evidenced by this Right 
Certificate shall have been exercised as provided in the Agreement.

          If any term, provision, covenant or restriction of the Agreement is 
held by a court of competent jurisdiction or other authority to be invalid, 
void or unenforceable, the remainder of 


                                      B-2

the terms, provisions, covenants and restrictions of the Agreement shall

purpose until it shall have been countersigned by the Rights Agent.

           AS DESCRIBED IN THE RIGHTS AGREEMENT, RIGHTS WHICH ARE

   OR AFFILIATES THEREOF (AS DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN

                        SUMMARY OF RIGHTS TO PURCHASE
                               PREFERRED SHARES
                                       
          On July 9, 1998 the Board of Directors of HILTON HOTELS CORPORATION 
(the "COMPANY") declared a dividend of one preferred share purchase right (a 
"Right") for each share of common stock, $2.50 par value (the "COMMON 
SHARES"), of the Company outstanding at the close of business on July 27, 
1998 (the "RECORD DATE").  As long as the Rights are attached to the Common 
Shares, the Company will issue one Right (subject to adjustment) with each 
new Common Share so that all such shares will have attached Rights.  When 
exercisable, each Right will entitle the registered holder to purchase from 
the Company one one-hundredth of a share of Series A Junior Participating 
Preferred Stock (the "PREFERRED SHARES") at a price of $140 per one 
one-hundredth of a Preferred Share, subject to adjustment (the "PURCHASE 
PRICE").  The description and terms of the Rights are set forth in a Rights 
Agreement, dated as of July 9, 1998, as the same may be amended from time to 
time (the "AGREEMENT"), between the Company and ChaseMellon Shareholder 
Services, L.L.C., as Rights Agent (the "RIGHTS AGENT").

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

          The Agreement provides that until the Distribution Date (or earlier 
redemption exchange, termination, or expiration of the Rights), the Rights 
will be transferred with and only with the Common Shares.  Until the 
Distribution Date (or earlier redemption or expiration of the Rights), new 
Common Share certificates issued after the close of business on the Record 
Date upon transfer or new issuance of the Common Shares will contain a 
notation incorporating the Agreement by reference.  Until the Distribution 
Date (or earlier redemption, exchange, termination or expiration of the 
Rights), the surrender for transfer of any certificates for Common Shares, 
with or without such notation or a copy of this Summary of Rights, will also 
constitute the transfer of the Rights associated with the Common Shares 
represented by such certificate.  As soon as practicable following the 
Distribution Date, separate certificates evidencing the Rights 


                                      C-1

<PAGE>

("RIGHT CERTIFICATES") will be mailed to holders of record of the Common 
Shares as of the close of business on the Distribution Date and such separate 
Right Certificates alone will evidence the Rights.

          The Rights are not exercisable until the Distribution Date.  The 
Rights will expire on July 27, 2008, subject to the Company's right to extend 
such date (the "FINAL EXPIRATION DATE"), unless earlier redeemed or exchanged 
by the Company or terminated.

          Each Preferred Share purchasable upon exercise of the Rights will 
be entitled, when, as and if declared, to a minimum preferential quarterly 
dividend payment of $1.00 per share but will be entitled to an aggregate 
dividend of 100 times the dividend, if any, declared per Common Share.  In 
the event of liquidation, dissolution or winding up of the Company, the 
holders of the Preferred Shares will be entitled to a minimum preferential 
liquidation payment of $100 per share (plus any accrued but unpaid dividends) 
but will be entitled to an aggregate payment of 100 times the payment made 
per Common Share.  Each Preferred Share will have 100 votes and will vote 
together with the Common Shares.  Finally, in the event of any merger, 
consolidation or other transaction in which Common Shares are exchanged, each 
Preferred Share will be entitled to receive 100 times the amount received per 
Common Share.  Preferred Shares will not be redeemable.  These rights are 
protected by customary antidilution provisions.  Because of the nature of the 
Preferred Share's dividend, liquidation and voting rights, the value of one 
one-hundredth of a Preferred Share purchasable upon exercise of each Right 
should approximate the value of one Common Share.

          The Purchase Price payable, and the number of Preferred Shares or 
other securities or property issuable, upon exercise of the Rights are 
subject to adjustment from time to time to prevent dilution (i) in the event 
of a stock dividend on, or a subdivision, combination or reclassification of 
the Preferred Shares, (ii) upon the grant to holders of the Preferred Shares 
of certain rights or warrants to subscribe for or purchase Preferred Shares 
or convertible securities at less than the current market price of the 
Preferred Shares or (iii) upon the distribution to holders of the Preferred 
Shares of evidences of indebtedness, cash, securities or assets (excluding 
regular periodic cash dividends at a rate not in excess of 125% of the rate 
of the last regular periodic cash dividend theretofore paid or, in case 
regular periodic cash dividends have not theretofore been paid, at a rate not 
in excess of 50% of the average net income per share of the Company for the 
four quarters ended immediately prior to the payment of such dividend, or 
dividends payable in Preferred Shares (which dividends will be subject to the 
adjustment described in clause (i) above)) or of subscription rights or 
warrants (other than those referred to above).

          In the event that a Person becomes an Acquiring Person or if the 
Company were the surviving corporation in a merger with an Acquiring Person 
or any affiliate or associate of an Acquiring Person and the Common Shares 
were not changed or exchanged, each holder of a Right, other than Rights that 
are or were acquired or beneficially owned by the Acquiring Person (which 
Rights will thereafter be void), will thereafter have the right to receive 
upon exercise that number of Common Shares having a market value of two times 
the then current Purchase Price of the Right.  In the event that, after a 
person has become an Acquiring Person, the Company were acquired in a merger 
or other business combination transaction or more than 50% of its 


                                      C-2

<PAGE>

assets or earning power were sold, proper provision shall be made so that 
each holder of a Right shall thereafter have the right to receive, upon the 
exercise thereof at the then current Purchase Price of the Right, that number 
of shares of common stock of the acquiring company which at the time of such 
transaction would have a market value of two times the then current Purchase 
Price of the Right.

          At the close of business on the tenth day following the first date 
of public announcement that a Person has become an Acquiring Person and prior 
to the earlier of one of the events described in the last sentence of the 
previous paragraph or the acquisition by such Acquiring Person of 50% or more 
of the outstanding Common Shares, the Board of Directors may cause the 
Company to exchange the Rights (other than Rights owned by an Acquiring 
Person which will have become void), in whole or in part, for Common Shares 
at an exchange rate of one Common Share per Right (subject to adjustment).  
The Board of Directors, with the concurrence of a majority of the Continuing 
Directors (as defined below), may extend the period during which the Rights 
are redeemable beyond the ten (10) days following the public announcement 
that a Person has become an Acquiring Person.  Under certain circumstances 
set forth in the Rights Agreement, the decision to redeem shall require the 
concurrence of a majority of the Continuing Directors.

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

          The Rights may be redeemed in whole, but not in part, at a price of 
$.01 per Right (the "REDEMPTION PRICE") by the Board of Directors at any time 
prior to the time that an Acquiring Person has become such.  The redemption 
of the Rights may be made effective at such time, on such basis and with such 
conditions as the Board of Directors in its sole discretion may establish. 
Immediately upon any redemption of the Rights, the right to exercise the 
Rights will terminate and the only right of the holders of Rights will be to 
receive the Redemption Price.

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

          Any of the provisions of the Agreement may be amended by the Board 
of Directors of the Company for so long as the Rights are then redeemable, 
and after the Rights are no longer redeemable, the Company may amend or 
supplement the Agreement in any manner that does not adversely affect the 
interests of the holders of the Rights.

A copy of the Agreement has been filed with the Securities and Exchange 
Commission as an Exhibit to a Current Report on Form 8-K.  A copy of the 
Agreement is available free of charge

                         HILTON HOTELS CORPORATION ADOPTS

                            NEW STOCKHOLDER RIGHTS PLAN

                           REPLACES EXPIRING HILTON PLAN

     BEVERLY HILLS, California, July 10, 1998 -- The Board of Directors of 
Hilton Hotels Corporation (NYSE:HLT) announced today the adoption of a new 
Preferred Share Purchase Rights Plan, effective July 27, 1998, to replace 
Hilton's current preferred share purchase rights plan, which will expire on 
July 27, 1998.  Under the new plan, one right will be distributed for each 
share of Hilton common stock outstanding at the close of business on July 27, 
1998.

     The Rights are not being distributed in response to any specific effort to
acquire control of the Company, nor is Hilton aware of any such effort.

     Initially, the Rights are attached to the common stock and are not
exercisable.  Subject to limited exceptions, the Rights become exercisable if a
person or group (other than Barron Hilton or the Conrad N. Hilton Fund) acquires
15% or more of Hilton's common stock or announces a tender offer for 15% or more
of the common stock.  Upon such event, each Right would entitle the holder to
buy one one-hundredth of a share of voting preferred stock at an exercise price
of  $140.

Stockholder Rights
2-2-2-2


     If a person acquires 15% or more of the outstanding common stock of Hilton,
each Right will entitle its holder to purchase, at the Right's then-current
exercise price, a number of shares of Hilton common stock having a market value
at that time of twice the Right's exercise price.  Rights held by the 15% holder
will become void and will not be exercisable to purchase shares at the bargain
purchase price.  If Hilton is acquired in a merger or other business combination
transaction which has not been approved by the Board of Directors, each Right
will entitle its holder to purchase, at the Right's then-current exercise price,
a number of the acquiring company's shares of common stock having a market value
at that time of twice the Right's exercise price.

     The new rights plan will expire on July 27, 2008.  The Board may elect to
redeem the rights at $.001 per right.  Distribution of the Rights is not taxable
to stockholders.

     Hilton Hotels Corporation is recognized internationally as the preeminent
gaming and hospitality company. The company develops, owns, manages or
franchises hotel-casinos, resorts, vacation ownership and hotel properties.
