ITEM 5. OTHER EVENTS

         On June 10, 1999, the Board of Directors of Mack-Cali Realty
Corporation (the "Company") authorized a dividend distribution (the
"Distribution") of one preferred share purchase right (a "Right") for each
outstanding share of common stock, par value $0.01 per share (the "Common
Shares"), of the Company. The dividend is payable on July 6, 1999 (the "Record
Date"), to the stockholders of record on that date. Each Right entitles the
registered holder to purchase from the Company one one-thousandth (1/1000) of a
share of Series A Junior Participating Preferred Stock, par value $.01 per share
(the "Preferred Shares"), of the Company at a price of $100.00 per one
one-thousandth of a Preferred Share (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a
Shareholder Rights Agreement (the "Rights Agreement"), dated as of July 6, 1999,
by and between the Company and ChaseMellon Shareholder Services, LLC, as rights
agent (the "Rights Agent").

         Initially, the Rights will be attached to all Common Share
certificates representing shares then outstanding, and no separate Rights
certificates will be distributed. The Rights will separate from the Common
Shares and a Distribution Date will occur upon the earlier of (i) ten calendar
days following the date (the "Shares Acquisition Date") of public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") has acquired, or obtained the right to acquire, beneficial ownership of
fifteen percent (15%) or more of the outstanding Common Shares or (ii) ten
calendar days (or such later date as may be determined by action of the Board of
Directors prior to the time any person or group of affiliated persons becomes an
Acquiring Person) following the commencement of, or public announcement of an
intent to commence, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of fifteen percent
(15%) or more of the outstanding Common Shares (the earlier of such dates being
called the "Distribution Date"). Until the Distribution Date, the Rights will be
evidenced by the Common Share certificates and will be transferred with and only
with such Common Share certificates. New Common Share certificates issued after
the Record Date will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date, the surrender for transfer of any
certificates representing outstanding Common Shares also will transfer the
Rights associated with the Common Shares represented by such certificate. Any
person or group owning in excess of 15% of the outstanding Common Shares as of
July 6, 1999, shall only trigger the effects referred to above if such person
increases its ownership of Common Shares to 10% or more greater than the
beneficial ownership of Common Shares of such Person on such date.

         As soon as practicable following the Distribution Date, separate
certificates representing 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 represent the
Rights.

<PAGE>


         The Rights are not exercisable until the Distribution Date. The Rights
will expire at the close of business on July 6, 2009 (the "Final Expiration
Date"), unless the Final Expiration Date is extended or the Right Certificates
are earlier redeemed or exchanged by the Company, as described below. Each Right
generally will entitle the holder to purchase one one-thousandth (1/1,000th) of
a Preferred Share of the Company at a price of $100.00.

         In the event that, following the Distribution Date, any person or group
becomes an Acquiring Person, each holder of a Right will thereafter have the
right to receive, upon exercise, Common Shares having a market value equal to
two times the Purchase Price of the Right. Notwithstanding any of the foregoing,
once any person or group becomes an Acquiring Person, all Rights that are or
were beneficially owned by any such Acquiring Person will be null and void.

         For example, at an exercise price of $100.00 per Right, each Right not
owned by an Acquiring Person would entitle its holder to purchase $200.00 worth
of Common Stock for $100.00. Assuming that the Common Stock had a per share
value of $40.00 on the date upon which such person or group became an Acquiring
Person, the holder of each valid right would be entitled to purchase five (5)
shares of Common Stock for $100.00.

         In the event that, following the Distribution Date, (i) the Company is
acquired in a merger or other business combination transaction in which the
Company is not the surviving corporation, or (ii) 50% or more of the Company's
consolidated assets or earning power is sold or transferred, then each holder of
a Right (except Rights which previously have been voided as set forth in the
preceding paragraph) shall thereafter have the right to receive, upon exercise,
common stock of the acquiring company having a value equal to two times the
Purchase Price of the Right.

         The Purchase Price payable, and the number of Preferred Shares (or
Common Shares) 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 the purchase of 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 or
assets (excluding regular quarterly cash dividends or dividends payable in
Preferred Shares) or of subscription rights or warrants (other than those
referred to above).

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

<PAGE>


         At any time after any person or group becomes an Acquiring Person, the
Board of Directors may cause the Company to exchange the Rights (other than
Rights owned by the Acquiring Person which shall have become void), in whole or
in part, at an exchange ratio of one Common Share per Right (subject to
adjustment).

         At any time prior to the earlier of (i) the close of business on the
tenth calendar day following the Shares Acquisition Date (or if the Shares
Acquisition Date shall have occurred prior to the Record Date, the close of
business on the tenth day following the Record Date) or (ii) the Final
Expiration Date, the Board of Directors of the Company may cause the Company to
redeem the Rights in whole, but not in part, at a price of $.0l per Right (the
"Redemption Price"). Under certain circumstances set forth in the Rights
Agreement, the decision to redeem shall required that there be Continuing
Directors (as defined below) in office and that a majority of the Continuing
Directors approve such decision. Immediately upon the action of the Board of
Directors of the Company electing to redeem the Rights, with, if required, the
concurrence of the Continuing Directors, the Company shall make announcement
thereof, and upon such action, 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 or exchanged, the holder thereof, as such,
will have no rights as a stockholder of the Company, including, without
limitation, the right to vote or to receive dividends.

         The term "Continuing Director" means any member of the Board of
Directors of the Company, while such Person is a member of the Board of
Directors, who (i) is not (A) an Acquiring Person or an Affiliate or Associate
of an Acquiring Person or (B) a representative or nominee of an Acquiring Person
or of any such Affiliate or Associate or (C) any Person elected to the Board of
Directors as a result of a proxy solicitation or initiative referred to in
Section 23(b); and (ii) either (A) was a member of the Board of Directors
immediately prior to the time any Person becomes an Acquiring Person or (B)
subsequently becomes a member of the Board of Directors, if such Person's
nomination for election or election to the Board of Directors is recommended or
approved by a majority of the Continuing Directors.

         The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, including an amendment
to lower certain thresholds described above to not less than the greater of (i)
the sum of one one-thousandth percent (.001%) and the largest percentage of the
outstanding Common Shares then known to the Company to be beneficially owned by
any person or group (other than Acquiring Persons) and (ii) ten percent (10%),
except that from and after such time as any person or group becomes an Acquiring
Person no such amendment may adversely affect the interests of the holders of
the Rights.

         The foregoing description of the Rights is qualified in its entirety by
reference to

         Shareholder Rights Agreement, dated as of July 6, 1999, between
Mack-Cali Realty Corporation, a Maryland corporation (the "Company"), and
ChaseMellon Shareholder Services, LLC, a New Jersey limited liability company,
as Rights Agent (the "Rights Agent").

                              W I T N E S S E T H:

         WHEREAS, the Board of Directors of the Company on June 10, 1999 (the
"Rights Dividend Authorization Date") authorized a dividend distribution (the
"Distribution") of one preferred share purchase right (a "Right") for each share
of Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
outstanding at the close of business on July 6, 1999 (the "Record Date"), each
Right representing the right to purchase, under certain circumstances, one
one-thousandth of a share of Preferred Stock (as hereinafter defined) of the
Company, and has further authorized and directed the issuance of one Right (as
such number may hereinafter be adjusted pursuant to the provisions of Section
11(p) hereof) with respect to each share of Common Stock issued and outstanding
between the Record Date and the earliest of the Distribution Date, the
Redemption Date or the Final Expiration Date (as such terms are hereinafter
defined;

         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:

              (a) "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 Stock
of the Company then outstanding, but shall not include the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company or any entity holding shares of Common Stock for or
pursuant to the terms of any such plan. Notwithstanding the foregoing, no person
shall become an "Acquiring Person" solely by virtue of its beneficial ownership,
on the date hereof, of 15% or more of the shares of Common Stock of the Company
outstanding as of the date hereof; provided, however, that if any Person that,
on the date hereof, beneficially owns 15% or more of the shares of Common Stock
of the Company outstanding as of the date hereof shall, after the date hereof,
acquire any additional shares of Common Stock of the Company such that such
Person's beneficial ownership of shares of Common Stock of the Company,
expressed as a percentage of the total number of shares of Common Stock of the
Company then outstanding, shall be 5% or more greater than the beneficial
ownership of shares of Common Stock of the Company of such Person on the date
hereof (expressed as a percentage of the total number of shares of Common Stock
of the Company outstanding on the date hereof), then such Person shall be deemed
to be an "Acquiring Person." Notwithstanding the foregoing, no Person shall
become an "Acquiring Person" as a result of an acquisition of shares of Common
Stock by the Company which, by reducing the number of shares outstanding,
increases the proportionate number of shares


1

<PAGE>


beneficially owned by such Person to 15% or more of the shares of Common Stock
of the Company then outstanding; provided, however, that if a Person shall
become the Beneficial Owner of 15% or more of the shares of Common Stock of the
Company then outstanding by reason of shares purchased by the Company and shall,
after such share purchases by the Company, become the Beneficial Owner of an
additional 1% or more greater than the beneficial ownership of shares of Common
Stock of the Company of such Person on the date thereof (expressed as a
percentage of the total number of shares of Common Stock of the Company then
outstanding), then such Person shall be deemed to be an "Acquiring Person."
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 paragraph (a),
has become such inadvertently, and such Person divests as promptly as
practicable a sufficient number of shares of Common Stock so that such Person
would no longer be an "Acquiring Person," then such Person shall not be deemed
to be an "Acquiring Person" for any purposes of this Agreement.

              (b) "Act" shall mean the Securities Act of 1933, as amended.

              (c) "Adjustment Shares" shall have the meaning set forth in
Section 11(a)(ii) hereof.

              (d) "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.

              (e) "Agreement" shall mean this Shareholder Rights Agreement,
dated as of July 6, 1999.

              (f) 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;

                   (ii) which such Person or any of such Person's Affiliates or
Associates has, directly or indirectly, (A) the right to acquire (whether such
right is exercisable immediately or only after the passage of time or upon the
occurrence of an event) pursuant to any agreement, arrangement or understanding
(whether or not in writing and 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 (other than these Rights), warrants or options, or otherwise;
provided, however, that a Person shall not be deemed the "Beneficial Owner" of,
or to "beneficially own," securities tendered pursuant to a tender or exchange
offer made by such Person or any of such Person's Affiliates or Associates until
such tendered securities are accepted for purchase or exchange or (B) the right
to vote pursuant to any agreement, arrangement or understanding; provided,
however, that a Person shall not be deemed the "Beneficial Owner" of, or to
"beneficially own," any security under this


2

<PAGE>


subparagraph (ii) 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 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 with which such Person or any of such Person's Affiliates or
Associates has any agreement, arrangement or understanding (whether or not in
writing and other than customary agreements with and between underwriters and
selling group members with respect to a bona fide public offering of securities)
for the purpose of acquiring, holding, voting (except pursuant to a revocable
proxy as described in the provision to subparagraph (ii)(B) of this paragraph
(f)) or disposing of any securities of the Company.

Notwithstanding the foregoing, nothing contained in this definition of
Beneficial Ownership shall cause a Person ordinarily engaged in business as an
underwriter of securities to be the "Beneficial Owner" of, or to "beneficially
own," any securities acquired in a bona fide firm commitment underwriting
pursuant to an underwriting agreement with the Company.

              (g) "Business Day" shall mean any day other than a Saturday,
Sunday, or a day on which banking institutions in the State of New York or the
state in which the principal office of the Rights Agent is located are
authorized or obligated by law or executive order to close.

              (h) "Certification" shall mean the certification concerning

5

<PAGE>


consummation of which would result in any Person becoming an Acquiring Person
(the earlier of the dates in subsections (i) and (ii) hereof being herein
referred to as the "Distribution Date"), (A) the Rights will be evidenced
(subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock registered in the names of the holders thereof
(which certificates also shall be deemed to be Right Certificates) and not by
separate Right Certificates, and (B) the right to receive Right Certificates

(and the Rights Agent will, if requested, send) by first-class, postage pre-paid
mail, to each record holder of Common Stock as of the close of business on the
Distribution Date, at the address of such holder shown on the records of the
Company, a Right certificate, in substantially the form set forth in Exhibit B
attached hereto (a "Right Certificate"), representing one Right for each share
of Common Stock so held, subject to adjustment as provided herein. As of the

Certificates.

Rights"), by first-class, postage pre-paid mail, to each record holder of Common
Stock as of the close of business on the Record Date, at the address of such
holder shown on the records of the Company. With respect to certificates for
shares of Common Stock outstanding as of the Record Date, until the Distribution
Date, the Rights will be represented by such certificates registered in the
names of the holders thereof, together with a copy of the Summary of Rights
attached thereto. Until the Distribution Date (or the earlier of the Redemption
Date or the Final Expiration Date), the surrender for transfer of any of the
certificates for Common Stock outstanding on the Record Date shall also
constitute the transfer of the Rights associated with the Common Stock
represented by such certificate.

              (c) Rights shall be issued in respect of all shares of Common
Stock issued after the Record Date but prior to the earlier of the Distribution
Date, the Redemption Date or the Final Expiration Date, or, in certain
circumstances provided in Section 22 hereof, after the Distribution Date.
Certificates representing such shares of Common Stock shall have impressed on,
printed on, written on or otherwise affixed to them the following legend:

         "This certificate also evidences and entitles the holder hereof to
         certain Rights as set forth in a Shareholder Rights Agreement between
         Mack-Cali Realty Corporation and ChaseMellon Shareholder Services, LLC,
         dated as of July 6, 1999 (the "Rights Agreement"), the terms of which
         are hereby incorporated herein by reference and a copy of which is on
         file at the principal executive offices of Mack-Cali Realty
         Corporation. Under certain circumstances set forth in the Rights
         Agreement, such Rights will be evidenced by separate certificates and
         will no longer be evidenced by this certificate. Mack-Cali Realty
         Corporation will mail to the holder of this certificate a copy of the
         Rights Agreement as in effect on the date of mailing without charge,
         after receipt of a written request therefor. Under certain
         circumstances set forth in the Rights Agreement, Rights issued to any
         Person who becomes an Acquiring Person (as defined


6

<PAGE>


         in the Rights Agreement) may become null and void."

After the due execution of any supplement or amendment to this Agreement in
accordance with the terms hereof, the reference to this Agreement in the
foregoing legend shall mean the Agreement as so supplemented or amended. Until
the Distribution Date, the Rights associated with the Common Stock represented
by certificates containing the foregoing legend shall be represented by such
certificates alone, and the surrender for transfer of any of such certificates
shall also constitute the transfer of the Rights associated with the Common
Stock represented thereby. In the event that the Company purchases or acquires
any shares of Common Stock after the Record Date but prior to the Distribution
Date, any Rights associated with such shares of Common Stock shall be deemed
canceled and retired so that the Company shall not be entitled to exercise any
Rights associated with the shares of Common Stock which are no longer
outstanding. The failure to print the foregoing legend on any such Common Stock
certificate or any other defect therein shall not affect in any manner
whatsoever the application or interpretation of the provisions of Section 7(e)
hereof.

         Section 4. FORM OF RIGHT CERTIFICATES. The Right Certificates (and the
forms of election to purchase shares and of assignment to be printed on the
reverse thereof) shall be substantially as set forth in Exhibit B attached
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate (which do not affect the duties or responsibilities of the Rights
Agent) 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 on
which the Rights may from time to time be listed, or to conform to usage.
Subject to the provisions of Section 11 and Section 22 hereof, the Right
Certificates, whenever distributed, shall entitle the holders thereof to
purchase such number of one one-thousandths of a share of Preferred Stock (or
following the occurrence of a Triggering Event, Common Stock) as shall be set
forth therein at the price per one one-thousandth of a share of Preferred Stock
set forth therein (the "Purchase Price"), but the number of such one
one-thousandths of a share of Preferred Stock 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 one of its authorized officers
either manually or by facsimile signature. The Right Certificates shall be
countersigned by an authorized signatory of the Rights Agent either manually or
by facsimile signature and shall not be valid for any purpose unless so
countersigned. In case any officer of the Company who shall have signed 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 an authorized
signatory of the Rights Agent and issued and delivered by the Company with the
same force and effect as though the person who signed such Right Certificates
had not ceased to be such officer of the Company; and any Right Certificate may
be signed on behalf of the Company by any Person who, at the actual date of the
execution of such Right Certificate, shall be a proper officer of the Company to
sign such Right Certificate, although at the date of the execution of this
Rights Agreement any such Person was not such an


7

<PAGE>


officer.

         In case any authorized signatory of the Rights Agent who shall have
countersigned any of the Right Certificates shall cease to be such signatory
before delivery by the Company, such Right Certificates, nevertheless, may be
issued and delivered by the Company with the same force and effect as though the
person who countersigned such Right Certificates had not ceased to be such
signatory; and any Right Certificate may be countersigned on behalf of the
Rights Agent by any Person who, at the actual date of the countersignature of
such Right Certificate, shall be a proper signatory of the Rights Agent to
countersign such Right Certificate, although at the date of the execution of
this Rights Agreement any such Person was not such a signatory.

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

         Section 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHT
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES. Subject
to the provisions of Section 14 hereof, at any time after the close of business
on the Distribution Date, and at or prior to the close of business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become null and void pursuant to Section 11(a)(ii) hereof or
that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Right Certificate or Right
Certificates, entitling the registered holder to purchase a like number of one
one-thousandths of a share of Preferred Stock (or following the occurrence of a
Triggering Event, Common Stock) as the Right Certificate or Right Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Right Certificate or
Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose, along with a signature guarantee and such other and
further documentation as the Rights Agent may reasonably request. 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 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 and shall
have provided such additional evidence, as the Company or the Rights Agent shall
reasonably request, of the identity of the Beneficial Owner, Affiliates or
Associates thereof or of the holder, or of any other Person with which such
holder or any of such holder's Affiliates or Associates has any agreement,
arrangement or understanding (whether or not in writing) for the purpose of
acquiring, holding, voting or disposing of securities of the Company. 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 a Right Certificate holder of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Right
Certificates.

<PAGE>


         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, along with a signature guarantee and
such other further documentation as the Rights Agent may reasonably request,
and, at the Company's request, reimbursement to the Company and the Rights Agent
of all reasonable expenses incidental thereto, and upon surrender to the Rights
Agent and cancellation of the Right Certificate if mutilated, the Company will
make and deliver a new Right Certificate of like tenor to the Rights Agent for
delivery to the registered owner in lieu of the Right Certificate so lost,
stolen, destroyed or mutilated .

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

              (a) The registered holder of any Right Certificate may exercise
the Rights evidenced thereby (except as otherwise provided herein) in whole or
in part at any time after the Distribution Date upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the designated office of the Rights Agent,
together with payment of the aggregate Purchase Price for the total number of
one one-thousandths of shares of Preferred Stock (or following the occurrence of
a Triggering Event, Common Stock) as to which the Rights are then being
exercised, at or prior to the earliest of (i) the close of business on July 6,
2009 (the "Final Expiration Date"), (ii) the time at which the Rights are
exchanged as provided in Section 24 hereof, or (iii) the time at which the
Rights are redeemed as provided in Section 23 hereof (the "Redemption Date") .

              (b) The Purchase Price for each one one-thousandth of a share of
Preferred Stock purchasable pursuant to the exercise of a Right shall initially
be $100.00, shall be subject to adjustment from time to time as provided in
Sections 11 and 13 hereof and shall be payable in accordance with paragraph (c)
below.

              (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the number of one one-thousandths of shares of
Preferred Stock (or following the occurrence of a Triggering Event, Common
Stock) to be purchased and an amount equal to any applicable tax or governmental
charge required to be paid, the Rights Agent shall thereupon promptly (i)
requisition from any transfer agent of Preferred Stock certificates representing
the number of one one-thousandths of a share of Preferred Stock to be purchased,
and the Company hereby irrevocably authorizes its transfer agent to comply with
all such requests; (ii) if the Company shall have elected to deposit the total
number of shares of Preferred Stock issuable upon exercise of the Rights
hereunder with a depositary agent, requisition from the depositary agent
depositary receipts representing such number of one one-thousandths of a share
of Preferred Stock as are to be purchased (in which case certificates for the
shares of Preferred Stock represented by such receipts shall be deposited by the
transfer agent with the depositary agent), and the Company hereby directs the
depositary agent to comply with such request; (iii) when necessary to comply
with this Agreement, requisition from any transfer agent of the Common Stock of
the Company certificates for the total number of shares of Common Stock to be
paid in accordance with


9

<PAGE>


Sections 11(a)(ii) and 11(a)(iii); (iv) when necessary to comply with this
Agreement, requisition from the Company the amount of cash to be paid in lieu of
issuance of fractional shares in accordance with Section 14 hereof; (v) 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 (vi) when necessary to comply with this Agreement, after receipt,
promptly deliver such cash to or upon the order of the registered holder of such
Right Certificate. The payment of the Purchase Price may be made in cash or by
certified bank check, bank draft or money order payable to the order of the
Company.

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

              (e) Notwithstanding anything in this Agreement to the contrary,
from and after the first occurrence of an event specified in Section 11(a)(ii)
hereof, any Rights beneficially owned by (i) an Acquiring Person or any
Associate or Affiliate of an Acquiring Person; (ii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee after
the Acquiring Person became such; or (iii) a transferee of an 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 (whether or not in writing) regarding the
transferred Rights or (B) a transfer which the Board of Directors of the Company
has determined is a part of an agreement, arrangement or understanding (whether
or not in writing) which has as a primary purpose or effect the avoidance of
this Section 7(e), shall become null and void without any further action, and no
holder of such Rights shall have any rights whatsoever with respect to such
Rights, whether under any provision of this Agreement or otherwise. The Company
shall notify the Rights Agent when this Section 7(e) is applicable and shall use
all reasonable efforts to insure that the provisions of this Section 7(e) are
complied with, but neither the Company nor the Rights Agent shall have any
liability to any holder of Right Certificates or other Person as a result of the
Company's failure to make any determinations with respect to an Acquiring Person
or its Affiliates, Associates or transferees hereunder.

              (f) Notwithstanding anything in this Agreement to the contrary,
neither the Rights Agent nor the Company shall be obligated to undertake any
action with respect to a registered holder upon the occurrence of any purported
exercise as set forth in this Section 7 unless such registered holder shall have
(i) properly completed and signed the certificate contained in the form of
election to purchase set forth on the reverse side of the Right Certificate
surrendered for such exercise; and (ii) provided such additional evidence of the
identity of the Beneficial Owner, Affiliates or Associates thereof or of the
holder, or of any other Person with which such holder or any of such holder's
Affiliates or Associates has any agreement,


10

<PAGE>


arrangement or understanding (whether or not in writing) for the purpose of
acquiring, holding, voting or disposing of any securities of the Company as the
Company or the Rights Agent 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, 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 SHARES OF STOCK. (a) The
Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued shares of Preferred Stock (or
following the occurrence of a Triggering Event, Common Stock) or any shares of
Preferred Stock (or following the occurrence of a Triggering Event, Common
Stock), the number of shares of Preferred Stock (or following the occurrence of
a Triggering Event, Common Stock) that will be sufficient to permit the exercise
in full of all outstanding Rights (it being understood that any of the foregoing
shares or securities may also be reserved for other purposes) or will take such
other steps as are appropriate to assure that the number of such shares
sufficient to permit the exercise in full of all outstanding Rights will be
available upon such exercise.

              (b) So long as the shares of Preferred Stock (and, following the
occurrence of an event specified in Sections 11(a)(ii) or Section 13 hereof,
Common Stock) and/or other securities issuable upon the exercise of Rights may
be listed on any national securities exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable (but
only to the extent that the Company's Board of Directors determines that it is
reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such exchange upon official notice of issuance
upon such exercise.

              (c) The Company shall use its best efforts (i) (A) to file, as
soon as practicable following the first occurrence of an event specified in
Section 11(a)(ii) hereof, or as soon as required by law, as the case may be, a
registration statement under the Act, with respect to the securities purchasable
upon exercise of the Rights on an appropriate form, (B) to cause such
registration statement to become effective as soon as practicable after such
filing, and (C) to cause such registration statement to remain effective (with a
prospectus at all times meeting the requirements of the Act) until the earlier
of (i) the date as of which the Rights are no longer exercisable for such
securities, and (ii) the Expiration Date; and (ii) to (A) file appropriate
applications with any state or federal regulatory bodies having jurisdiction
over the issuance of the securities (or assets) purchasable upon exercise of the
Rights in order to obtain any approvals


11

<PAGE>


or orders of such bodies as may be legally required, (B) cause such approvals to
be obtained or orders to be issued as soon as practicable after such filing and
(C) cause such approvals or orders to remain effective until the earlier of (1)
the date as of which the Rights are no longer exercisable for such securities
(or assets), and (2) the Expiration Date, to the extent not previously obtained.
The Company also will take such action as may be appropriate under the blue sky
laws of the various states. The Company may temporarily suspend, (i) for a
period of time not to exceed ninety (90) days after the date set forth in clause
(i)(A) of the first sentence of this Section 9(c), the exercisability of the
Rights in order to prepare and file such registration statement and permit it to
become effective and (ii) for a period of time not in excess of 180 days after
such date (or for such longer period as is required by any applicable law, rule
or regulation of any appropriate regulatory bodies ), the exercisability of the
Rights in order to obtain any such required regulatory body approvals or orders.
Upon any such suspension, the Company shall issue a public announcement and
shall give simultaneous written notice to the Rights Agent stating that the
exercisabi1ity of the Rights has been temporarily suspended, as well as a public
announcement and notice to the Rights Agent 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 qualifications in such jurisdiction shall have been obtained.

              (d) The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all shares of the Preferred Stock (or
following the occurrence of a Triggering Event, Common Stock) 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.

              (e) The Company further covenants and agrees that it will pay when
due and payable any and all taxes and governmental charges which may be payable
in respect of the issuance or delivery of the Right Certificates or of any
shares of the Preferred Stock (or following the occurrence of a Triggering
Event, Common Stock) upon the exercise of Rights. The Company shall not,
however, be required (i) 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 Stock (or following the
occurrence of a Triggering Event, Common Stock) in a name other than that of,
the registered holder of the Right Certificate representing Rights surrendered
for exercise or (ii) to issue or deliver any certificates for shares of the
Preferred Stock (or following the occurrence of a Triggering Event, Common
Stock) 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 STOCK RECORD DATE. Each Person in whose name any
certificate for any number of shares of Preferred Stock (or following the
occurrence of a Triggering Event, Common Stock) is issued upon the exercise of
Rights shall for all purposes be deemed to have become the holder of record of
the shares of Preferred Stock (or following the occurrence of a Triggering
Event, Common Stock) represented thereby on, and such certificate shall be
dated, the date upon which the Right Certificate representing such Rights was
duly surrendered and


12

<PAGE>


payment of the Purchase Price (and any applicable taxes and governmental
charges) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Stock (or Common Stock) transfer
books of the Company are closed, such person shall be deemed to have become
the record holder of such shares on, and such certificate shall be dated, the
next succeeding Business Day on which the Preferred Stock (or Common Stock)
transfer books of the Company are open. Prior to the exercise of the Rights
represented thereby, the holder of a Right Certificate shall not be entitled
to any rights of a stockholder of the Company with respect to shares for
which the Rights shall be exercisable, including, without limitation, the
right to vote, to receive dividends or other distributions or to exercise any
preemptive rights, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein.

         Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR NUMBER OF
RIGHTS. The Purchase Price, the number of one one-thousandths of a share of
Preferred Stock covered by each Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 11.

              (a) (i) In the event the Company shall at any time after the date
of this Agreement (A) authorize a dividend on the Preferred Stock payable in
shares of the Preferred Stock, (B) subdivide the outstanding Preferred Stock,
(C) combine the outstanding Preferred Stock into a smaller number of shares or
(D) issue any shares of its stock in a reclassification of the Preferred Stock
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), except
as otherwise provided in this Section 11(a) and Section 7(e) hereof, the
Purchase Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification, and the
number and kind of shares of Preferred Stock or stock, as the case may be,
issuable on such date, shall be proportionately adjusted so that the holder of
any Right exercised after such time shall be entitled to receive upon payment of
the Purchase Price then in effect the aggregate number and kind of shares of
stock which, if such Right had been exercised immediately prior to such date and
at a time when the Preferred Stock (or Common Stock) transfer books of the
Company were open, he or she would have owned upon such exercise and been
entitled to receive by virtue of such dividend, subdivision, combination or
reclassification. If an event occurs which would require an adjustment under
both this Section 11(a)(i) and Section 11(a)(ii), the adjustment provided for in
this Section 11(a)(i) shall be in addition to, and shall be made prior to, any
adjustment required pursuant to Section 11(a)(ii).

                   (ii) Subject to Sections 23 and 24 of this Agreement, in
the event any Person becomes an Acquiring Person, each holder of a Right
shall thereafter have a right to receive, upon exercise thereof at a price
equal to the then current Purchase Price multiplied by the number of one
one-thousandths of a share of Preferred Stock for which such Right is then
exercisable, in accordance with the terms of this Agreement and in lieu of
shares of Preferred Stock, such number of shares of the Common Stock of the
Company as shall equal the result obtained by (1) multiplying the then
current Purchase Price by the number of one one-thousandths of a share of
Preferred Stock for which a Right is then exercisable and dividing that
product by (2) 50% of the then current per share market price of the Common
Stock of the

13

<PAGE>


Company (determined pursuant to Section 11(d) hereof) on the date of the
occurrence of such event (such number of shares are hereinafter referred to
as the "Adjustment Shares").

         From and after the occurrence of such event, any Rights that are or
were acquired or beneficially owned by any Acquiring Person (or any Associate or
Affiliate of such Acquiring Person) shall be null and void, and any holder of
such Rights shall thereafter have no right to exercise such Rights under any
provision of this Agreement. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person whose rights would be null and void pursuant to the preceding sentence or
any Associate or Affiliate thereof. No Right Certificate shall be issued at any
time upon the transfer of any Rights to an Acquiring Person whose Rights would
be null and void pursuant to the preceding sentence or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate. Any Right Certificate delivered to the Rights Agent for transfer to
an Acquiring Person whose Rights would be null and void pursuant to the
preceding sentence shall be canceled.

                   (iii) In the event that the number of shares of Common Stock
which are authorized by the Company's charter but not outstanding or reserved
for issuance for purposes other than upon exercise of the Rights are not
sufficient to permit the exercise in full of the Rights in accordance with the
foregoing subparagraph (ii), the Company shall take all such action as may be
necessary to authorize additional shares of Common Stock for issuance upon
exercise of the Rights, and the Company may, in the discretion of the Board of
Directors of the Company, and shall, in the event the Company shall be unable to
take all such action as may be necessary to authorize such additional shares of
Common Stock, substitute, for each share of Common Stock that would otherwise be
issuable upon exercise of a Right, a number of shares of Preferred Stock or
fraction thereof such that the current per share market price of one share of
Preferred Stock multiplied by such number or fraction is equal to the current
per share market price of one share of Common Stock as of the date of issuance
of such share of Preferred Stock or fraction thereof.

              (b) In case the Company shall fix a record date for the issuance
of rights, options or warrants to all holders of Preferred Stock entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Stock (or securities having substantially
the same rights, privileges and preferences as the shares of Preferred Stock
("Equivalent Preferred Stock")) or securities convertible into Preferred Stock
or Equivalent Preferred Stock at a price per share of Preferred Stock or
Equivalent Preferred Stock (or having a conversion price per share, if a
security convertible into Preferred Stock or Equivalent Preferred Stock) less
than the then current per share market price of the Preferred Stock or
Equivalent Preferred Stock, as the case may be, on such record date, the
Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the number of shares of Preferred
Stock outstanding on such record date plus the number of shares of Preferred
Stock or Equivalent Preferred Stock which the aggregate offering price of the
total number of


14

<PAGE>


shares of Preferred Stock and/or Equivalent Preferred Stock so to be offered
(and/or the aggregate initial conversion price of the convertible securities so
to be offered) would purchase at such current market price and the denominator
of which shall be the number of shares of Preferred Stock outstanding on such
record date plus the number of additional shares of Preferred Stock and/or
Equivalent Preferred Stock to be offered for subscription or purchase (or into
which the convertible securities so to be offered are initially convertible);
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
stock of the Company issuable upon exercise of one Right. In case such
subscription price may be paid by delivery of 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. Shares of
Preferred Stock owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation. Such adjustment
shall be made successively whenever such a record date is fixed; and in the
event that such rights, options or warrants are not so issued, the Purchase
Price shall be adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.

              (c) In case the Company shall fix a record date for the making of
a distribution to all holders of Preferred Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Stock) or subscription rights or warrants (excluding those referred to
in Section 11 (b) hereof), the Purchase Price to be in effect after such record
date shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
then current per share market price of the Preferred Stock on such record date,
less the fair market value (as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent) of the portion of the assets or evidences of
indebtedness so to be distributed or of such subscription rights or warrants
applicable to one share of Preferred Stock and the denominator of which shall be
such current per share market price of the Preferred Stock; provided, however,
that in no event shall the consideration to be paid upon the exercise of one
Right be less than the aggregate par value of the shares of capital stock to the
Company to be issued upon exercise of one Right. Such adjustments shall be made
successively whenever such a record date is fixed; and in the event that such
distribution is not so made, the Purchase Price shall again be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.

              (d) (i) For the purpose of any computation hereunder, the "current
per share market price" of any security (a "Security" for the purpose of this
Section 11(d)(i)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the 30 consecutive Trading Days
(as such term is hereinafter defined) immediately prior to (but not including)
such date; provided, however, that in the event that the current per share
market price of the Security is determined during the period following the
announcement by the issuer of such Security of (A) a dividend or distribution on
such Security payable in shares of such Security or securities convertible into
such shares or (B) any subdivision, combination or reclassification of such
Security, and prior to the expiration of the requisite 30 Trading Day period,
after the ex-dividend date for such dividend or distribution, or the record date
for such


15

<PAGE>


subdivision, combination or reclassification, then, and in each such case, the
current per share market price shall be appropriately adjusted to reflect the
current per share market price 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 1isted 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 the National Association of Securities Dealers, Inc. Automated
Quotation System ("NASDAQ") or such other system then in use, or, if on any such
date the Security is not quoted by 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 market maker is making a market in the Common Stock, the fair value
of such shares on such date shall be as determined in good faith by the
Independent Directors if the Independent Directors constitute a majority of the
Board of Directors or, in the event the Independent Directors do not constitute
a majority of the Board of Directors, by an independent investment banking firm
selected by the Board of Directors, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes.
The term "Trading Day" shall mean a day on which the principal national
securities exchange on which the Security is listed or admitted to trading is
open for the transaction of business or, if the Security is not listed or
admitted to trading on any national securities exchange, a Business Day.

                   (ii) For the purpose of any computation hereunder, the
"current per share market price" of the Preferred Stock shall be determined in
accordance with the method set forth in Section 11(d)(i). If the Preferred Stock
is not publicly held or listed or traded in any manner described in clause (i)
of this Section 11(d), the "current per share market price" of the Preferred
Stock shall be conclusively deemed to be the current per share market price of
the Common Stock as determined pursuant to Section 11(d)(i), multiplied by
1,000. If neither the Common Stock nor the Preferred Stock is publicly held or
so listed or traded, "current per share market price" of the Preferred Stock
shall mean the fair value per share as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes. For all
purposes of this Agreement, the "current per share market price" of one
one-thousandths of a share of Preferred Stock shall be equal to the "current per
share market price" of one share of Preferred Stock divided by 1,000.

              (e) Anything herein to the contrary notwithstanding, no adjustment
in the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least 1% in the Purchase Price; provided, however,
that any adjustments which by reason of this Section 11(e) are not required to
be made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this Section 11 shall be made to the nearest


16

<PAGE>


cent or to the nearest one one-millionth of a share of Preferred Stock or one
ten-thousandth of a share of Common Stock, as the case may be. Notwithstanding
the first sentence of this Section 11(e), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three years from the
date of the transaction which mandates such adjustment or (ii) the Final
Expiration Date.

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

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

              (h) Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase Price as a
result of the calculations made in Section 11(b) and (c), each Right outstanding
immediately prior to the making of such adjustment shall thereafter evidence the
right to purchase, at the adjusted Purchase Price, that number of shares
(calculated to the nearest one one-millionth) obtained by (i) multiplying (A)
the number of shares of Preferred Stock covered by a Right immediately prior to
such adjustment by (B) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

              (i) The Company may elect on or after the date of any adjustment
of the Purchase Price to adjust the number of Rights, in substitution for any
adjustment in the number of shares of Preferred Stock purchasable upon the
exercise of a Right. Each of the Rights outstanding after such adjustment of the
number of Rights shall be exercisable for the number of shares of Preferred
Stock for which a Right was exercisable immediately prior to such adjustment.
Each Right held of record prior to such adjustment of the number of Rights shall
become that number of Rights (calculated to the nearest one ten-thousandth)
obtained by dividing the Purchase Price in effect immediately prior to
adjustment of the Purchase Price by the Purchase Price in effect immediately
after the adjustment of the Purchase Price. The Company shall make a public
announcement (and shall give simultaneous written notice to the Rights Agent) of
its election to adjust the number of Rights, indicating the record date for the
adjustment to be made. This record date may be the date on which the Purchase
Price is adjusted


17

<PAGE>


or any day thereafter, but, if the Right Certificates have been issued, shall be
at least 10 days later than the date of the public announcement. If Right
Certificates have been issued, upon each adjustment of the number of Rights
pursuant to this Section 11(i), the Company shall, as promptly as practicable,
cause to be distributed to holders of Right Certificates on such record date
Right Certificates representing, subject to Section 14 hereof, the additional
Rights to which such holders shall be entitled as a result of such adjustment,
or, at the option of the Company, shall cause to be distributed to such holders
of record in substitution and replacement for the Right Certificates held by
such holders prior to the date of adjustment, and upon surrender thereof, if
required by the Company, new Right Certificates representing all the Rights to
which such holders shall be entitled after such adjustment. Right Certificates
so to be distributed shall be issued, executed and countersigned in the manner
provided for herein and shall be registered in the names of the holders of
record of Right Certificates on the record date specified in the public
announcement.

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

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

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

              (m) Anything in this Section 11 to the contrary notwithstanding,
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that the Board of Directors of the Company, in its sole discretion,
shall determine to be advisable in order that any consolidation or subdivision
of shares of Preferred Stock, issuance wholly for cash of any of shares of
Preferred Stock at less than the current per share market price, issuance wholly
for cash of the Preferred Stock or securities which by their terms are
convertible into or exchangeable for Preferred Stock, dividends on Preferred
Stock payable in shares of Preferred Stock or issuance of rights, options


18

<PAGE>


or warrants referred to hereinabove in Section 11(b), hereafter made by the
Company to holders of its Preferred Stock shall not be taxable to such
stockholders.

              (n) The Company covenants and agrees that, after the Distribution
Date, it will not, except as permitted by Sections 23, 24 and 27 hereof, take
(nor will it permit any of its Subsidiaries to take) any action if at the time
such action is taken it is reasonably foreseeable that such action will diminish
substantially or otherwise eliminate the benefits intended to be afforded by the
Rights.

              (o) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, (i) consolidate with any other Person (other
than a Subsidiary of the Company in a transaction which complies with Section
11(n)), (ii) merge with or into any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(n)), or (iii) sell or
transfer (or permit any of its Subsidiaries to sell or transfer), in one or more
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to, any
other Person or Persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(n)) if (x) at
the time of or immediately after such consolidation, merger or sale 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 or (y) prior to,
simultaneously with or immediately after such consolidation, merger or sale, the
stockholders of the Person specified in Section 13(a) hereof shall have received
a distribution of Rights previously owned by such Person or any of its
Affiliates and Associates.

              (p) Anything in this Agreement to the contrary notwithstanding, in
the event that the Company shall at any time after the Record Date and prior to
the Distribution Date (i) authorize a dividend on the outstanding shares of
Common Stock payable in shares of Common Stock or (ii) effect a subdivision,
combination or consolidation of the outstanding shares of Common Stock into a
greater or lesser number of shares of Common Stock, then in any such case (A)
the number of one one-thousandths of a share of Preferred Stock purchasable
after such event upon proper exercise of each Right shall be determined by
multiplying the number of one one-thousandths of a Preferred Share so
purchasable immediately prior to such event by a fraction, the numerator of
which is the number of shares of Common Stock outstanding immediately prior to
such event and the denominator of which is the number of shares of Common Stock
outstanding immediately after such event, and (B) each share of Common Stock
outstanding immediately after such event shall have issued with respect to it
that number of Rights which each share of Common Stock outstanding immediately
prior to such event had issued with respect to it. The adjustments provided for
in this Section 11(p) shall be made successively whenever such a dividend is
authorized, declared or paid or such a subdivision, combination or consolidation
is effected.

              (q) Notwithstanding anything in this Agreement to the contrary,
prior to the Distribution Date, the Company may, in lieu of making any
adjustment to the Purchase Price, the number of shares of Preferred Stock
eligible for purchase on exercise of each Right or the


19

<PAGE>


number of Rights outstanding, which adjustment would otherwise be required by
Section 11(a)(1), 11(b), 11(c), 11(h) or 11(i), make such other equitable
adjustment or adjustments thereto as the Board of Directors (whose determination
shall be conclusive) deems appropriate in the circumstances and not inconsistent
with the objectives of the Board of Directors in adopting this Agreement and
such Sections.


         Section 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES.
Whenever an adjustment is made as provided in Sections 11 or 13 hereof the
Company shall promptly (a) prepare a certificate setting forth such adjustment,
and a brief, reasonably detailed statement of the facts, computations and
accounting for such adjustment, (b) file with the Rights Agent and with each
transfer agent for the Preferred Stock and the Common Stock a copy of such
certificate and (c) mail a brief summary thereof to each holder of a Right
Certificate in accordance with Section 26 hereof. The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained, and shall have no duty with respect to and shall not be obligated or
responsible for calculating any adjustment, nor shall it be deemed to have
knowledge of such an adjustment unless and until it shall have received such
certificate.

         Section 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR
EARNING POWER. In the event that, following the Shares Acquisition Date,
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 of such consolidation or merger, (b) any Person shall
consolidate with, or merge with and into the Company and the Company shall be
the continuing or surviving corporation of such consolidation or merger and, in
connection with such consolidation or merger, all or part of the Common Stock
shall be changed into or exchanged for stock or other securities of any other
Person (or the Company) or cash or any other property, or (c) the Company shall
sell or otherwise transfer (or one or more of its Subsidiaries shall sell or
otherwise transfer), in one or more transactions, assets or earning power
aggregating 50% or more of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Company or any of its wholly-owned Subsidiaries, then, and in each such case
proper provision shall be made so that (i) each holder of a Right (except as
otherwise provided herein) shall thereafter have the right to receive, upon the
exercise thereof at the then current Purchase Price in accordance with the terms
of this Agreement, such number of validly issued, fully paid, non-assessable and
freely tradable shares of common stock of such other Person (including the
Company as successor thereto or as the surviving corporation) as shall be equal
to the result obtained by (A) multiplying the then current Purchase Price by the
number of one one-thousandths of a share of Preferred Stock for which a Right is
then exercisable by (B) 50% of the then current per share market price of the
common stock of such other Person (determined pursuant to Section 11(d) hereof)
on the date of consummation of such consolidation, merger, sale or transfer;
(ii) the issuer of such common stock shall thereafter be liable for, and shall
assume, by virtue of such consolidation, merger, sale or transfer, all the
obligations and duties of the Company pursuant to this Agreement; (iii) the term
"Company" shall thereafter be deemed to refer to such issuer; and (iv) such
issuer shall take such steps (including, but not limited to, the reservation of
a sufficient number of shares of its common stock in accordance with Section 9
hereof) in connection with such consummation as may be


20

<PAGE>


necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to the shares of its common stock
thereafter deliverable upon the exercise of the Rights.

              (b) The Company shall not consummate any such consolidation,
merger, sale or transfer unless prior thereto the Company and such issuer shall
have executed and delivered to the Rights Agent a supplemental agreement so
providing.

         The Company shall not enter into any transaction of the type referred
to in this Section 13 if at the time of such transaction there are any rights,
warrants, instruments or securities outstanding or any agreements or
arrangements which, as a result of the consummation of such transaction, would
eliminate or substantially diminish the benefits intended to be afforded by the
Rights. The provisions of this Section 13 shall similarly apply to successive
consolidations, mergers, sales or other transfers.

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

              (b) The Company shall not be required to issue fractions of shares
of Preferred Stock (other than fractions which are integral multiples of one
one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which represent fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock). In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-thousandth of a share of Preferred Stock,
the Company shall pay to the registered holders of Right Certificates at the
time the Rights represented thereby are


21

<PAGE>


exercised as herein provided an amount in cash equal the same fraction of the
current market value of one one-thousandth of a share of Preferred Stock. For
purposes of this Section 14(b), the current market value one one-thousandth of a
share of Preferred Stock shall be one one-thousandth of the closing price of a
share of Preferred Stock (as determined pursuant to Section 11(d)(ii) hereof)
for the Trading Day immediately prior to the date of such exercise.


              (c) The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right, except as otherwise provided by this Section 14.

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

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

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

              (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the office of the Rights Agent designated for such purpose, duly endorsed and
accompanied by a proper instrument of transfer, along with a signature guarantee
and such other and further documentation as the Rights Agent may reasonably
request;

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


22

<PAGE>


affected by any notice to the contrary;

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

         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 number of shares of
Preferred Stock or any other securities of the Company which may at any time be
issuable on the exercise of the Rights represented thereby, nor shall anything
contained herein or in any Right Certificate be construed to confer upon the
holder of any Right Certificate, as such, any of the rights of a stockholder of
the Company or any right to vote for the election of directors or upon any
matter submitted to stockholders at any meeting thereof, or to give or withhold
consent to any corporate action, or to receive notice of meetings or other
actions affecting stockholders (except as provided in Section 25 hereof), or to
receive dividends or subscription rights, or otherwise, until the Right or
Rights represented 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 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
any action taken, suffered or omitted by the Rights Agent in connection with the
acceptance and administration of this Agreement or the exercise or performance
of its duties hereunder, including, without limitation, the costs and expenses
of defending against any claim of 1iability in the premises.

         The Rights Agent shall be protected and shall incur no liability for or
in respect of any action taken, suffered or omitted by it in connection with its
administration of this Agreement or the exercise or performance of its duties
hereunder, in reliance upon any Right Certificate or certificate for shares of
Preferred Stock or Common Stock or for other securities of the Company,
instrument of assignment or transfer, power of attorney, endorsement, affidavit,
letter, notice, direction, consent, instruction, adjustment notice, 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.


23

<PAGE>


         Notwithstanding anything in this Agreement to the contrary, in no event
shall the Rights Agent be liable for special, indirect or consequential loss or
damage of any kind whatsoever (Including but not limited to lost profits), even
if the Rights Agent has been advised of the likelihood of such loss or damage
and regardless of the form of the action.

         The indemnity provided for in this Section 18 shall survive the
expiration of the Rights, the termination of this Agreement, and the resignation
or removal of the Rights Agent. The costs and expenses of enforcing this right
of indemnification also shall be paid by the Company.

         Section 19. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.
Any Person into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any Person resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any Person succeeding to the shareholder services 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
Person would be eligible for appointment as a successor Rights Agent under the
provisions of Section 21 hereof. In case, at the time such successor Rights
Agent shall succeed to the agency created by this Agreement, any of the Right
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of the predecessor so countersigned
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 the 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 expressly imposed by this Agreement (and no implied
duties or obligations shall be read into this Agreement against the Rights
Agent) upon the following terms and conditions, by all of which the Company and
the holders of Right Certificates, by their acceptance thereof, shall be bound:

              (a) The Rights Agent may consult with legal counsel (who may be
legal counsel for the Company), and the written advice or opinion of such
counsel shall be full and complete authorization and protection to the Rights
Agent and the Rights Agent shall incur no liability for or in respect of any
action taken, suffered or omitted by it in good faith and in


24

<PAGE>


accordance with such advice or opinion.

              (b) Whenever in the performance of its duties under this Agreement
the Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking, suffering or omitting any
action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Executive Vice President or Vice
President, the Treasurer or the Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization and protection to
the Rights Agent and the Rights Agent shall incur no liability for or in respect
of any action taken, suffered or omitted in good faith by it under the
provisions of this Agreement in reliance upon such certificate.

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

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

              (e) The Rights Agent shall not be under any liability or
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 or any adjustment in the terms of the Rights (including the manner,
method or amount of any such adjustment), or for ascertaining the existence of
facts that would require any such change or adjustment (except with respect to
the exercise of Rights represented by Right Certificates after actual notice
that such change or adjustment is required); nor shall it by any act hereunder
be deemed to make any representation or warranty as to the authorization or
reservation of any shares of Preferred Stock to be issued pursuant to this
Agreement or any Right Certificate or as to whether any shares of Preferred
Stock will, when issued, be validly authorized and issued, fully paid and
nonassessable.

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

              (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder and
certificates delivered pursuant to any provision hereof from any one of the
Chairman of the Board, the Chief Executive Officer, the President, any Executive
Vice President or Vice President, the Secretary or the Treasurer of the Company,
and is authorized to apply to such officers for advice or instructions in
connection


25

<PAGE>


with its duties, and it shall not be liable for any action taken, suffered or
omitted by it in good faith in accordance with instructions of any such officer.
An application by the Rights Agent for written instructions by the Company may
set forth in writing any action proposed to be taken or omitted by the Rights
Agent with respect to its duties and obligations under this Agreement and the
date on or after which such action shall be taken or such commission shall be
effective. The Rights Agent shall not be liable for any action taken or omitted
in accordance with a proposal included in any such application on or after the
date specified therein (which date shall not be less than five Business Days
after the Company receives such application) without the consent of the Company
unless, prior to taking or omitting such action, the Rights Agent has received
written instructions in response to application specifying the actions to be
taken or omitted, as the case may be.

              (h) The Rights Agent and any stockholder, affiliate, director,
officer or employee of the Rights Agent may buy, sell or deal in any of the
Rights or any 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 Person
or legal entity.

              (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company or any other Person resulting from any
such act, default, neglect or misconduct, so long as the Rights Agent was not
grossly negligent.

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

              (k) If, with respect to any Right Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed or indicates an affirmative response, the Rights Agent shall not
take any further action with respect to such requested exercise or transfer
without first consulting the Company. The Company shall give the Rights Agent
prompt written instructions as to the action to be taken regarding the Right
Certificates involved. The Rights Agent shall not be liable for acting in
accordance with such instructions.

              (l) The Rights Agent shall not be required to take notice or be
deemed to have notice of any fact, event or determination (including, without
limitation, any dates or events defined in this Agreement or the designation of
any Person as an Acquiring Person, Affiliate or Associate) under this Agreement
unless and until the Rights Agent shall be specifically notified in writing by
the Company of such fact, event or determination.

<PAGE>


         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' written notice mailed to the Company and to each transfer
agent of the Preferred Stock and the Common Stock by registered or certified
mail, and, at the Company's expense, to the holders of the Right Certificates by
first class mail. The Company may remove the Rights Agent or any successor
Rights Agent upon thirty (30) days' written notice, mailed to the Rights Agent
or successor Rights Agent, as the case may be, and to each transfer agent of the
Preferred Stock and the Common Stock by registered or certified mail, and to the
holders of the Right Certificates by first-class mail. If the Rights Agent shall
resign or be removed or otherwise shall become incapable of acting, the Company
shall appoint a successor to the Rights Agent. If the Company shall fail to make
such appointment within a period of 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, in good standing, 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 or which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $25
million. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Company shall file written notice thereof with
the predecessor Rights Agent and each transfer agent of the Preferred Stock and
the Common Stock, and mail a written notice thereof to the registered holders of
the Right Certificates. Failure to give any notice provided for in this Section
21, however, or any defect therein, shall not affect the legality or validity of
the resignation or removal of the Rights Agent or the appointment of the
successor Rights Agent, as the case may be.

         Section 22. ISSUANCE OF NEW RIGHT CERTIFICATES. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Right Certificates representing Rights in such
form as may be approved by its Board of Directors to reflect any adjustment or
change in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of shares of Common Stock following the Distribution
Date and prior to the redemption or expiration the Rights, the Company (a)
shall, with respect to shares of Common Stock so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, or upon the
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


27

<PAGE>


with such issuance or sale; provided, however, that (i) no such Right
Certificate shall be issued if, and to the extent that, the Company shall be
advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Right Certificate would be issued, and (ii) no such Right Certificate shall be
Issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof .

         Section 23. REDEMPTION AND TERMINATION. (a) Subject to the provisions
of paragraph (b) below, the Board of Directors of the Company may, at its
option, at any time prior to the earlier of (i) the close of business on the
tenth calendar day following the Shares Acquisition Date (or if the Shares
Acquisition Date shall have occurred prior to the Record Date, the close of
business on the tenth day following the Record Date) or (ii) the close of
business on the Final Expiration Date, redeem all but not less than all of the
then outstanding Rights at a redemption price of $.0l per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price"). Subject to the terms hereof and to the
immediately preceding sentence, the redemption of the Rights by the Board of
Directors may be made effective at such time, on such basis and on such
conditions as the Board of Directors in its sole discretion may establish. The
Company may, at its option, pay the Redemption Price either in shares of its
Common Stock (valued at their then current per share market price as defined in
Section 11(d)(i) on the date of the redemption), other securities, cash or other
assets. Notwithstanding anything contained in this Agreement to the contrary,
the Rights shall not be exercisable after the first occurrence of an event
specified in Section 11(a)(ii) hereof until such time as the Company's right of
redemption under this Section 23(a) has expired.

              (b) If the Board of Directors of the Company, pursuant to
paragraph (a) above, authorizes redemption of the Rights in the circumstances
set forth below, then there must be Continuing Directors in office and such
authorization shall require the approval of at least a majority of the
Continuing Directors: such authorization occurs within one hundred eighty (180)
days after the earlier to occur of (i) the Share Acquisition Date or (ii) the
date of a change (resulting from a proxy or consent solicitation or similar
shareholder initiative) in a majority of the directors of the Company in office
at the commencement of such solicitation or initiative if any Person who is a
participant in such solicitation or initiative has stated (or if upon the
commencement of such solicitation or initiative a majority of the directors of
the Company has determined in good faith) that such Person (or any of its
Affiliates or Associates) intends to take, or may consider taking, any action
which would result in such Person becoming an Acquiring Person or which would
cause the occurrence of a Trigger Event.

              (c) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, 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 held. The
Company shall promptly give public notice of any such redemption; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such redemption. The Company shall give notice of such
redemption to the holders of the then


28

<PAGE>


outstanding Rights by mailing such notice to the Rights Agent and 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 Stock. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of redemption will state the method by which the
payment of the Redemption Price will be made. Neither the Company nor any of its
Affiliates or Associates may redeem, acquire or purchase for value any Rights at
any time in any manner other than that specifically set forth in this Section 23
or in Section 24 hereof, and other than in connection with the repurchase of
Common Stock prior to the Distribution Date.

         Section 24. EXCHANGE. (a) The Board of Directors of the Company may, at
its option, by resolution adopted at any time after any Person becomes an
Acquiring Person, provide that the Company shall exchange all or part of the
then outstanding and exercisable Rights (which shall not include Rights that
have become null and void pursuant to the provisions of Section 7(e) hereof) for
shares of Common Stock at an exchange ratio of one share of Common Stock per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio").

              (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of shares of Common Stock equal
to the number of such Rights held by such holder multiplied by the Exchange
Ratio. The Company shall promptly give 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. Promptly after the action of the Board of
Directors ordering an exchange of the Rights, the Company shall give notice of
any such exchange to the Rights Agent and the holders of the then outstanding
Rights by mailing such notice to all such holders at each holder's last address
as it appears upon the registry books of the Rights Agent. Any notice which is
mailed in the manner herein provided shall be deemed given, whether or not the
holder receives the notice. Each such notice of exchange will state the method
by which the exchange of the shares of Common Stock for Rights will be effected
and, in the event of any partial exchange, the number of Rights which will be
exchanged. Any partial exchange shall be effected pro rata based on the number
of Rights (other than Rights which have become void pursuant to the provisions
of Section 7(e) hereof) held by each holder of Rights.

              (c) In any exchange pursuant to this Section 24, the Company, at
its option, may substitute shares of Preferred Stock (or Equivalent Preferred
Stock, as such term is defined in Section 11(b) hereof) for shares of Common
Stock exchangeable for the Rights, at the initial rate of one one-thousandth of
a share of Preferred Stock (or Equivalent Preferred Stock) for each share of
Common Stock, as appropriately adjusted to reflect adjustments in the dividend
rights of the Preferred Stock pursuant to the terms thereof.

              (d) In the event that there shall not be sufficient shares of
Common Stock


29

<PAGE>


issued, but not outstanding, or authorized but unissued, to permit any exchange
of Rights as contemplated in accordance with this Section 24, the Company shall
take all such action as may be necessary to authorize additional Common Stock
for issuance upon exchange of the Rights, and the Company may, in the discretion
of the Board of Directors of the Company, and shall, in the event the Company
shall be unable to take all such action as may be necessary to authorize such
additional shares of Common Stock, substitute, for each share of Common Stock
that would otherwise be issuable upon exchange of a Right, a number of shares of
Preferred Stock or fraction thereof such that the current per share market price
of one share of Preferred Stock multiplied by such number or fraction is equal
to the current per share marker price of one share of Common Stock as of the
date of issuance of such shares of Preferred Stocks or fraction thereof.

              (e) The Company shall not be required to issue fractional shares
of Common Stock or to distribute certificates which represent fractional shares
of Common Stock. In lieu of such fractional shares of Common Stock, the Company
shall pay to the registered holders of the Right Certificates with regard to
which such fractional shares of Common Stock would otherwise be issuable an
amount in cash equal to the same fraction of the current market value of a whole
share of Common Stock. For the purposes of this paragraph (e), the current
market value of a whole share of Common Stock shall be the closing price of a
share of Common Stock (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of exchange
pursuant to this Section 24.

              (f) In any exchange pursuant to this Section 24, the Company, at
its option, may substitute for any share of Common Stock exchangeable for a
Right (i) equity securities of the Company deemed to have the same value as
shares of Common Stock, (ii) cash, (iii) debt securities of the Company, (iv)
other assets, or (v) any combination of the foregoing, having an aggregate value
which a majority of the Independent Directors and the Board of Directors of the
Company shall have determined in good faith to be equal to the then current per
share market price of Common Stock (determined pursuant to Section 11(d) hereof)
on the Trading Date immediately preceding the date of exchange pursuant to this
Section 24.

         Section 25. NOTICE OF CERTAIN EVENTS. In case the Company shall propose
at any time following the Distribution Date (a) to pay any dividend payable in
stock of any class to the holders of its Preferred Stock or to make any other
distribution to the holders of its Preferred Stock (other than a regular
quarterly cash dividend); (b) to offer to the holders of its Preferred Stock
rights or warrants to subscribe for or to purchase any additional shares of
Preferred Stock or shares of stock of any class or any other securities, rights
or options; (c) to effect any reclassification of Preferred Stock (other than a
reclassification involving only the subdivision of outstanding Preferred Stock);
(d) to effect any consolidation or merger into or with any other Person 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; (e) to effect the liquidation, dissolution or
winding up of the Company; or (f) to authorize, declare or pay any dividend on
the shares of Common Stock payable in shares of Common Stock or to effect a
subdivision, combination or consolidation of the shares of Common Stock (by
reclassification or


30

<PAGE>


otherwise than by payment of dividends in shares of Common Stock), then, in each
such case, the Company shall give to the Rights Agent and to each holder of a
Right, in accordance with Section 26 hereof, a notice of such proposed action,
which shall specify the record date for the purposes of such stock dividend or
distribution of rights or warrants, or the date on which such reclassification,
consolidation, merger, sale, transfer, liquidation, dissolution, or winding up
is to take place and the date of participation therein by the holders of the
Preferred Stock and/or Common Stock, if any such date is to be fixed, and such
notice shall be so given in the case of any action covered by clause (a) or (b)
above at least ten (10) days prior to the record date for determining holders of
the Preferred Stock for purposes of such action and, in the case of any such
other action, at least 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 Stock, whichever shall be the earlier.

         In case an event set forth in Section 11(a)(ii) hereof shall occur,
then, in any such case, the Company shall as soon as practicable thereafter give
to the Rights Agent and to each holder of a Right, in accordance with Section 26
hereof, a notice of the occurrence of such event, which notice shall specify
such event and the consequences of such event to holders of Rights under Section
11(a)(ii) hereof.

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

Without limiting the foregoing, the Company may, at any time prior to such time
as any Person becomes an Acquiring Person, amend this Agreement to lower the
thresholds set forth in Sections 1(a) and 3(a) hereof to not less than the
greater of (a) the sum of .001% and the largest percentage of the outstanding
shares of Common Stock then known by the Company to be beneficially owned by any
Person (other than any Person that, on the date hereof, beneficially owns 15% or
more of the shares of Common Stock of the Company outstanding as of the date
hereof and other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
holding shares of Common Stock for or pursuant to the terms of any such plan)
and (b) 10%. From and after the Distribution Date, the Company may, and the
Rights Agent shall, if the Company so directs, from time to time supplement or
amend any provision of this Agreement without the approval any holder of Right
Certificates in order (a) to cure any ambiguity, (b) to correct or supplement
any provision contained herein which may be defective or inconsistent with any
of other provisions herein, (c) to shorten or lengthen any time period hereunder
(provided that any shortening of the time periods set forth in Section 23 hereof
shall be effective only if there are Continuing Directors and shall require a
majority of such Continuing Directors), or (d) to change or supplement the
provisions hereunder in any manner which the Company may deem necessary or
desirable and which shall not adversely affect the interests of the holders of
Right Certificates (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person); PROVIDED, HOWEVER, that from and after the Distribution
Date, this Agreement may not be supplemented or amended to lengthen, pursuant to
clause (c) of this sentence, (i) a time period relating to when the Rights may
be redeemed at such time as the Rights are not then redeemable or (ii) any other
time period unless such lengthening is for the purpose of protecting, enhancing
or clarifying the rights of, and the benefits to, the holders of Rights (other
than an Acquiring Person or any Affiliate or Associate of an Acquiring Person).
Prior to the Distribution Date, the interests of the holders of Rights shall be
coincident with the interests of the holders of shares of Common Stock of the
Company. Upon the delivery of a certificate from an appropriate officer of the
Company or, so long as any Person is an Acquiring Person, from the majority of
the Company's Board of Directors, which states that the proposed supplement or
amendment is in compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment. Notwithstanding anything in this
Agreement to the contrary, no supplement or amendment to this Agreement that
changes the rights and duties of the Rights Agent under this Agreement will be
effective without the consent of the Rights Agent.

         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. DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS. For
all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common Stock
of which any Person is the Beneficial Owner, shall be


32

<PAGE>


made in accordance with the provisions of Rule 13d-3(d)(1)(i) of the General
Rules and Regulations under the Exchange Act. The Board of Directors of the
Company (and, where specifically provided for herein, the Continuing Directors
or Independent Directors) shall have the exclusive power and authority to
administer this Agreement and to exercise all rights and powers specifically
granted to the Board of Directors or the Company (or, as expressly provided, the
Continuing Directors or Independent Directors), 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 a determination to redeem or not
redeem the Rights or to amend this Agreement) . All such actions, calculations,
interpretations and determinations (including, for the purpose of clause (ii)
below, all omissions with respect to the foregoing) which are done or made by
the Board of Directors (or, as provided for, by the Continuing Directors or
Independent Directors) in good faith (i) shall be final, conclusive and binding
on the Company, the Rights Agent, the holders of the Right Certificates and all
other Persons, and (ii) shall not subject the Board of Directors or the
Continuing Directors or Independent Directors to any liability to the holders of
the Right Certificates.

         Section 30. BENEFITS OF THIS AGREEMENT. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Right Certificates (and, prior to the Distribution
Date, the Common Stock) 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, of the Common Stock).

         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;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the close of business on the
tenth day following the date of such determination by the Board of Directors.

         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 Maryland 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; except that all provisions regarding the
rights, duties and obligations of the Rights Agent under this Agreement shall be
governed by and construed in accordance with the laws of the State of New York
applicable to contracts made and to be performed entirely within such state.

         Section 33. COUNTERPARTS. This Agreement may be executed in any number


33

<PAGE>


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.

         Section 34. DESCRIPTIVE HEADINGS. Descriptive headings of the several
Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                          MACK-CALI REALTY CORPORATION
                                     FORM OF
                             ARTICLES SUPPLEMENTARY
                                       FOR
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                 (Pursuant to Sections 2-105(a)(9) and 2-208(a)
                    of the Maryland General Corporation Law)



         MACK-CALI REALTY CORPORATION, a Maryland corporation (the "Company")
hereby certifies to the State Department of Assessments and Taxation of Maryland
that:

         FIRST: Pursuant to authority conferred upon the Board of Directors
by the charter of the Company (the "Charter"), the Board of Directors, as
required by Section 2-208 of the Maryland General Corporation Law, pursuant
to resolutions adopted at a meeting duly called on June 10, 1999, classified
and designated 200,000 shares (the "Shares") of authorized but unissued
Preferred Stock (as defined in the Charter) as shares of Series A Junior
Participating Preferred Stock, with the preferences, conversion and other
rights, voting powers, restrictions, limitations as to dividends and other
distributions, qualifications and terms and conditions of redemption as
follows, which upon any restatement of the Charter shall be made part of
Article IV of the Charter, with any necessary or appropriate changes to the
enumeration or lettering of sections or subsections hereof:

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

         Section 1. DESIGNATION AND AMOUNT. This series of Preferred Stock shall
be designated the "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares which shall constitute the Series A
Preferred Stock shall be 200,000 shares. 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 Company
convertible into Series A Preferred Stock.

         Section 2. DIVIDEND RIGHTS. (a) Subject to the rights of holders of any
shares of any series of Preferred Stock (or any similar stock) ranking prior and
superior to the Series A Preferred Stock with respect to dividends, the holders
of shares of Series A Preferred Stock, in preference to the holders of Common
Stock, par value $0.01 per share (the "Common Stock"), of the Company and of any
other junior stock, shall be entitled to receive, when, as and if


A-1

<PAGE>


authorized by the Board of Directors out of assets legally available for the
purpose, quarterly dividends payable in cash on the first business day of April,
July, October and January in each year (each such date being referred to herein
as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly
Dividend Payment Date after the first issuance of a share or fraction of a share
of Series A Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the greater of (i) $1.00 or (ii) subject to the provision for
adjustment hereinafter set forth, 1,000 times the aggregate per share amount of
all cash dividends, and 1,000 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions (other than a dividend
payable in shares of Common Stock) or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise)) authorized 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 Board
of Directors of the Company shall at any time (A) authorize, declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or (ii) effect a
subdivision or combination or consolidation of the outstanding 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 Series A Preferred Stock were entitled
immediately prior to such event under clause (ii) 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 Company shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (a) of this Section 1
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 Shares shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

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


A-2

<PAGE>


date shall be no 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 1,000
votes on all matters submitted to a vote of the stockholders of the Company. In
the event the Company shall at any time (i) declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or (ii) effect a subdivision or
combination or consolidation of the outstanding 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 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 articles
supplementary 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 stock of the Company having general voting rights
shall vote together as one class on all matters submitted to a vote of
stockholders of the Company.

              (c) Except as set forth herein, holders of shares 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 authorized or declared, on shares of Series A
Preferred Stock outstanding shall have been paid in full, the Company shall not:

                   (i) authorize, 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) authorize, 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;


A-3

<PAGE>


                   (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) with the Series A Preferred Stock,
provided that the Company may at any time redeem, purchase or otherwise acquire
shares of any such junior stock in exchange for shares of any stock of the
Company ranking junior (either as to dividends or 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 Company shall not permit any subsidiary of the Company to
purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company 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 Company 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 Charter or
in any other articles supplementary creating a series of Preferred Stock or as
otherwise required by law.

         Section 6. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (a) 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 $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not
authorized or 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 as hereinafter set
forth, equal to 1,000 times the aggregate amount to be distributed per share to
holders of shares of Common Stock, or (b) 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 Board of Directors of
the Company shall at any time authorize, declare or pay any dividend on the
combination or consolidation of the outstanding shares of Common Stock payable
in shares of Common Stock, or effect a subdivision or combination or


A-4

<PAGE>


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 (a) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction,
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

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

         Section 9. RANKING . The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution, winding up or otherwise, junior to all series of the
Company's Preferred Stock, unless the terms of any such series shall provide
otherwise.

         Section 10. AMENDMENT. The Charter, including these Articles
Supplementary establishing the rights and preferences of the Series A Preferred
Stock, shall not be amended in any manner which would materially alter or change
the preferences, voting powers or other rights or restrictions of the Series A
Preferred Stock, as set forth herein, so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Preferred Stock, voting together as a single class.

         Section 11. RESTRICTIONS AND LIMITATIONS. Shares of Series A Preferred
Stock shall be subject to the restrictions and limitations set forth in Article
VI of the Charter.


A-5

<PAGE>


         Section 12. 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.

         Section 13. NO CONVERSION RIGHTS. The holders of the Series A Preferred
Stock shall not have any rights to convert such shares into shares of any other
class or series of stock of the Company or into any other securities of, or
interest in, the Company.

         Section 14. NO PREEMPTIVE RIGHTS. No holder of shares of Series A
Preferred Stock shall have any preemptive or preferential right to subscribe
for, or to purchase, any additional shares of stock of the Company of any class
or series, or any other security of the Company which the Company may issue or
sell.

         SECOND: The Shares have been classified and designated by the Board of
Directors under the authority contained in the Charter.

         THIRD: These Articles Supplementary have been approved by the Board of
Directors in the manner and by the vote required by law.

acknowledges these Articles Supplementary to be the corporate act of the Company
and, as to all matters or facts required to be verified under oath, the

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK


         On June 10, 1999, the Board of Directors of Mack-Cali Realty
Corporation (the "Company") authorized a dividend distribution (the
"Distribution") of one preferred share purchase right (a "Right") for each
outstanding share of common stock, par value $0.01 per share (the "Common
Shares"), of the Company. The dividend is payable on July 6, 1999 (the "Record
Date"), to the stockholders of record on that date. Each Right entitles the
registered holder to purchase from the Company one one-thousandth of a share of
Series A Junior Participating Preferred Stock, par value $.01 per share (the
"Preferred Shares"), of the Company at a price of $100.00 per one one-thousandth
of a Preferred Share (the "Purchase Price"), subject to adjustment. The
description and terms of the Rights are set forth in a Shareholder Rights
Agreement (the "Rights Agreement") by and between the Company and ChaseMellon
Shareholder Services, LLC, as rights agent (the "Rights Agent").

DISTRIBUTION DATE; TRANSFER OF RIGHTS

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) ten calendar days following
the date (the "Shares Acquisition Date") of public announcement that a person or
group of affiliated or associated persons (an "Acquiring Person") have acquired,
or obtained the right to acquire, beneficial ownership of fifteen percent (15%)
or more of the outstanding Common Shares (the "Share Acquisition Date") or (ii)
ten calendar days (or such later date as may be determined by action of the
Board of Directors prior to the time any person or group of affiliated persons
becomes an Acquiring Person) following the commencement of, or public
announcement of an intent to commence, a tender offer or exchange offer the
consummation of which would result in the beneficial ownership by a person or
group of fifteen percent (15%) or more of the outstanding Common Shares (the
earlier of such dates being called the "Distribution Date"). Until the
Distribution Date, the Rights will be evidenced by the Common Share certificates
and will be transferred with and only with such Common Share certificates. New
Common Share certificates issued after the Record Date will contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date,
the surrender for transfer of any certificates representing outstanding Common
Shares also will transfer the Rights associated with the Common Shares
represented by such certificate. Any person or group owning in excess of 15% of
the outstanding Common Shares as of July 6, 1999, shall only trigger the effects
referred to above if such person increases its ownership of Common Shares to 5%
or more greater than the beneficial ownership of Common Shares of such Person on
such date.

         As soon as practicable following the Distribution Date, separate
certificates representing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Shares as of


C-1

<PAGE>


the close of business on the Distribution Date and such separate Right
Certificates alone will represent the Rights.

         The Rights are not exercisable until the Distribution Date. The Rights
will expire at the close of business on July 6, 2009 (the "Final Expiration
Date"), unless the Final Expiration Date is extended or the Right Certificates
are earlier redeemed or exchanged by the Company, as described below. Each Right
generally will entitle the holder to purchase one one-thousandth (1/1,000th) of
a Preferred Share of the Company at a price of $100.00.

EXERCISE OF RIGHTS FOR COMMON STOCK OF THE COMPANY ("FLIP-IN" PROVISION)

         In the event that, following the Distribution Date, any person or group
becomes an Acquiring Person, each holder of a Right will thereafter have the
right to receive, upon exercise, Common Shares having a market value equal to
two times the Purchase Price of the Right. Notwithstanding any of the foregoing,
once any person or group becomes an Acquiring Person, all Rights that are or
were beneficially owned by any such Acquiring Person will be null and void.

         For example, at an exercise price of $100.00 per Right, each Right not
owned by an Acquiring Person would entitle its holder to purchase $200.00 worth
of Common Stock for $100.00. Assuming that the Common Stock had a per share
value of $40.00 on the date upon which such person or group became an Acquiring
Person, the holder of each valid right would be entitled to purchase five (5)
shares of Common Stock for $100.00.

EXERCISE OF RIGHTS FOR SHARES OF THE ACQUIRING COMPANY ("FLIP-OVER" PROVISION)

         In the event that, following the Distribution Date, (i) the Company is
acquired in a merger or other business combination transaction in which the
Company is not the surviving corporation, or (ii) 50% or more of the Company's
consolidated assets or earning power is sold or transferred, then each holder of
a Right (except Rights which previously have been voided as set forth in the
preceding paragraph) shall thereafter have the right to receive, upon exercise,
common stock of the acquiring company having a value equal to two times the
Purchase Price of the Right.

ADJUSTMENTS TO PURCHASE PRICE

         The Purchase Price payable, and the number of Preferred Shares (or
Common Shares) 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 pr 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 or
assets (excluding regular quarterly cash dividends or dividends payable in
Preferred Shares) or of subscription rights or warrants (other


C-2

<PAGE>


than those referred to above).

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

REDEMPTION AND EXCHANGE OF RIGHTS

         At any time after any person or group becomes an Acquiring Person, the
Board of Directors may cause the Company to exchange the Rights (other than
Rights owned by the Acquiring Person which shall have become void), in whole or
in part, at an exchange ratio of one Common Share per Right (subject to
adjustment).

         At any time prior to the earlier of (i) the close of business on the
tenth calendar day following the Shares Acquisition Date (or if the Shares
Acquisition Date shall have occurred prior to the Record Date, the close of
business on the tenth day following the Record Date) or (ii) the Final
Expiration Date, the Board of Directors of the Company may cause the Company to
redeem the Rights in whole, but not in part, at a price of $.0l per Right (the
"Redemption Price"). Under certain circumstances set forth in the Rights
Agreement, the decision to redeem shall required that there be Continuing
Directors (as defined below) in office and that a majority of the Continuing
Directors approve such decision. Immediately upon the action of the Board of
Directors of the Company electing to redeem the Rights, with, if required, the
concurrence of the Continuing Directors, the Company shall make announcement
thereof, and upon such action, 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 or exchanged, the holder thereof, as such,
will have no rights as a stockholder of the Company, including, without
limitation, the right to vote or to receive dividends.

         The term "Continuing Director" means any member of the Board of
Directors of the Company, while such Person is a member of the Board of
Directors, who (i) is not (A) an Acquiring Person or an Affiliate or Associate
of an Acquiring Person or (B) a representative or nominee of an Acquiring Person
or of any such Affiliate or Associate or (C) any Person elected to the Board of
Directors as a result of a proxy solicitation or initiative referred to in
Section 23(b); and (ii) either (A) was a member of the Board of Directors
immediately prior to the time any Person becomes an Acquiring Person or (B)
subsequently becomes a member of the Board of Directors, if such Person's
nomination for election or election to the Board of Directors is recommended or
approved by a majority of the Continuing Directors.

AMENDMENT

         The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, including an amendment
to lower certain thresholds described above to not less than the greater of (i)
the sum of one one-thousandth percent (.001%) and the largest percentage of the
outstanding Common Shares then known to the Company to be beneficially owned by
any person or group (other than Acquiring Persons) and (ii) ten percent (10%),
except that from and after such time as any person or group becomes an Acquiring
Person no such amendment may adversely affect the interest of the holders of the
Rights.

                          MACK-CALI REALTY CORPORATION

                             ARTICLES SUPPLEMENTARY
                                       FOR
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                 (Pursuant to Sections 2-105(a)(9) and 2-208(a)
                    of the Maryland General Corporation Law)



         MACK-CALI REALTY CORPORATION, a Maryland corporation (the "Company")
hereby certifies to the State Department of Assessments and Taxation of Maryland
that:

         FIRST: Pursuant to authority conferred upon the Board of Directors
by the charter of the Company (the "Charter"), the Board of Directors, as
required by Section 2-208 of the Maryland General Corporation Law, pursuant
to resolutions adopted at a meeting duly called on June 10, 1999, classified
and designated 200,000 shares (the "Shares") of authorized but unissued
Preferred Stock (as defined in the Charter) as shares of Series A Junior
Participating Preferred Stock, with the preferences, conversion and other
rights, voting powers, restrictions, limitations as to dividends and other
distributions, qualifications and terms and conditions of redemption as
follows, which upon any restatement of the Charter shall be made part of
Article IV of the Charter, with any necessary or appropriate changes to the
enumeration or lettering of sections or subsections hereof:

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

         Section 1. DESIGNATION AND AMOUNT. This series of Preferred Stock shall
be designated the "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares which shall constitute the Series A
Preferred Stock shall be 200,000 shares. 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 Company
convertible into Series A Preferred Stock.

         Section 2. DIVIDEND RIGHTS. (a) Subject to the rights of holders of any
shares of any series of Preferred Stock (or any similar stock) ranking prior and
superior to the Series A Preferred Stock with respect to dividends, the holders
of shares of Series A Preferred Stock, in preference to the holders of common
stock, par value $0.01 per share (the "Common Stock"), of the Company and of any
other junior stock, shall be entitled to receive, when, as and if authorized by
the Board of Directors out of assets legally available for the purpose,
quarterly dividends payable in cash on the first business day of April, July,
October and January in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or


<PAGE>


fraction of a share of Series A Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (i) $1.00 or (ii) subject to the
provision for adjustment hereinafter set forth, 1,000 times the aggregate per
share amount of all cash dividends, and 1,000 times the aggregate per share
amount (payable in kind) of all non-cash dividends or other distributions (other
than a dividend payable in shares of Common Stock) or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise))
authorized 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 Board of Directors of the Company shall at any
time (A) authorize, declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or (ii) effect a subdivision or combination or
consolidation of the outstanding 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 Series A Preferred Stock were entitled immediately prior to such
event under clause (ii) 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 Company shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (a) of this Section 1
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 Shares shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

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


<PAGE>


              (a) Subject to the provision for adjustment hereinafter set forth,
each share of Series A Preferred Stock shall entitle the holder thereof to 1,000
votes on all matters submitted to a vote of the stockholders of the Company. In
the event the Company shall at any time (i) declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or (ii) effect a subdivision or
combination or consolidation of the outstanding 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 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 articles
supplementary 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 stock of the Company having general voting rights
shall vote together as one class on all matters submitted to a vote of
stockholders of the Company.

              (c) Except as set forth herein, holders of shares 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 authorized or declared, on shares of Series A
Preferred Stock outstanding shall have been paid in full, the Company shall not:

                   (i) authorize, 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) authorize, 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) with the Series A Preferred Stock,
provided that the Company may at any time redeem, purchase


<PAGE>


or otherwise acquire shares of any such junior stock in exchange for shares of
any stock of the Company ranking junior (either as to dividends or 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 Company shall not permit any subsidiary of the Company to
purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company 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 Company 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 Charter or
in any other articles supplementary creating a series of Preferred Stock or as
otherwise required by law.

         Section 6. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (a) 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 $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not
authorized or 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 as hereinafter set
forth, equal to 1,000 times the aggregate amount to be distributed per share to
holders of shares of Common Stock, or (b) 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 Board of Directors of
the Company shall at any time authorize, declare or pay any dividend on the
combination or consolidation of the outstanding shares of Common Stock payable
in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under the proviso in


<PAGE>


clause (a) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

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

         Section 9. RANKING. The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution, winding up or otherwise, junior to all series of the
Company's Preferred Stock, unless the terms of any such series shall provide
otherwise.

         Section 10. AMENDMENT. The Charter, including these Articles
Supplementary establishing the rights and preferences of the Series A Preferred
Stock, shall not be amended in any manner which would materially alter or change
the preferences, voting powers or other rights or restrictions of the Series A
Preferred Stock, as set forth herein, so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Preferred Stock, voting together as a single class.

         Section 11. RESTRICTIONS AND LIMITATIONS. Shares of Series A Preferred
Stock shall be subject to the restrictions and limitations set forth in Article
VI of the Charter.

         Section 12. 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.

<PAGE>


         Section 13. NO CONVERSION RIGHTS. The holders of the Series A Preferred
Stock shall not have any rights to convert such shares into shares of any other
class or series of stock of the Company or into any other securities of, or
interest in, the Company.

         Section 14. NO PREEMPTIVE RIGHTS. No holder of shares of Series A
Preferred Stock shall have any preemptive or preferential right to subscribe
for, or to purchase, any additional shares of stock of the Company of any class
or series, or any other security of the Company which the Company may issue or
sell.

         SECOND: The Shares have been classified and designated by the Board of
Directors under the authority contained in the Charter.

         THIRD: These Articles Supplementary have been approved by the Board of
Directors in the manner and by the vote required by law.

         FOURTH: The undersigned Chief Executive Officer of the Company
acknowledges these Articles Supplementary to be the corporate act of the Company
and, as to all matters or facts required to be verified under oath, the

to be executed under seal in its name and on its behalf by its Chief Executive

         NOW THEREFORE, in consideration of the foregoing, the mutual promises
contained herein and for other good and valuable consideration, the receipt and
sufficiency which is hereby acknowledged, the General Partner on behalf of
itself and the Limited Partners, intending to be legally bound, hereby agrees to
make the following amendments to the Partnership Agreement in connection with
the execution of Rights Agreement, and to make certain technical corrections to
the Partnership Agreement, effective as of the date first written above:

         Section 1 - DEFINED TERMS. Unless otherwise specifically provided for
herein, all capitalized terms shall have the same meaning given to such term in
the Partnership Agreement.

         Section 2 - AMENDMENTS.

         A. The definition of "Current Per Share Market Price" set forth in
Article 1 of the Partnership Agreement and is hereby deleted in its entirety and
amended to read in its entirety as following:

                  "CURRENT PER SHARE MARKET PRICE", on any date, shall mean the
         average of the Closing Price for the five (5) consecutive Trading Days
         ending on such date, provided that in the event that shares of stock
         exchanged for Partnership Units include Rights that a holder of such
         shares would be entitled to receive pursuant to the Rights Agreement,
         such Rights shall be deemed to have no value unless a "Triggering
         Event" (as defined in the Rights Agreement) shall have occurred (i.e.,
         if the Rights issued pursuant thereto are no longer "attached" to the
         stock and are able to trade independently); and provided further, that
         in the event that a


3

<PAGE>


         Triggering Event shall have occurred and any stock exchanged for
         Partnership Units includes Rights that the holder of such shares would
         be entitled to receive pursuant to the Rights Agreement, then the
         Current Per Share Market Price of such Rights shall be determined by
         the General Partner acting in good faith on the basis of such
         quotations and other information that it considers, in its reasonable
         judgment, appropriate.


         B. Article 1 of the Partnership Agreement is amended to add the
following terms as defined terms in the Partnership Agreement in appropriate
alphabetical order:

         "Rights" means the rights issued to the stockholders of the General
Partner pursuant to the Rights Agreement.

         "Rights Agreement" means that certain Shareholder Rights Agreement
dated as of July 6, 1999 by and between the General Partner and ChaseMellon
Shareholder Services, LLC, as Rights Agent.

         C. Section 6.4(c) of the Partnership Agreement entitled "Adjustments to
Partnership Units" is hereby deleted in its entirety and amended to read in its
entirety as follows:

                  (c) ADJUSTMENTS TO PARTNERSHIP UNITS. If the Common Stock (or
         any other class of stock of the General Partner for which a class of
         Partnership Units may be redeemed) undergoes any stock split or
         subdivision, reverse stock split or combination, stock dividends, or
         distribution of stock rights, warrants or options, then, without
         further action or consent by the General Partner or any Limited
         Partner, each corresponding class of Partnership Units that is
         redeemable for such


4

<PAGE>


         stock shall be split, combined, issued or distributed stock, stock
         rights, options or warrants in accordance with the same ratio used to
         split, combine, issue or distribute the stock, stock rights, options or
         warrants. For example, if the Common Stock undergoes a reverse
         two-for-one split, (i.e., every two shares of old Common Stock are
         converted to one share of new Common Stock) than the corresponding
         class of Partnership Units that are redeemable for such Common Stock
         shall undergo a similar reverse split (i.e., every two OP Units shall
         be converted into one new OP Unit). Similarly, if any class of
         Partnership Units into which another class of Partnership Units is
         convertible, undergoes any split or reverse split, then without further
         action or consent by the General Partner or any Limited Partner, the
         latter class of Partnership Units shall be split or combined in
         accordance with the same ratio used to split or combine the first class
         of Partnership Units. In addition, without limiting the generality of
         the foregoing, in the event the number of shares of Common Stock,
         preferred stock or any class of stock of the General Partner shall be
         adjusted for the issuance or distribution of stock upon the
         exercisability of the Rights governed by the Rights Agreement without
         the receipt of cash by the General Partner (which adjustment may be
         satisfied by the issuing of additional Common Stock or other stock in
         exchange for the Rights) then, without further action or consent by the
         General Partner or any Limited Partner, the corresponding classes of
         Partnership Units shall be appropriately issued additional Units or
         otherwise appropriately adjusted as necessary to reflect equitably the
         dilution in the stock of the General Partner


5

<PAGE>


         resulting from the issuance of additional stock and the exchange of
         stock for the Rights.

         D. The Partnership Agreement is hereby amended by adding a new
section 6.3A to read as follows:

                           6.3A EXERCISE OF THE RIGHTS PURSUANT TO THE RIGHTS
                  AGREEMENT. In the event that the General Partner has made
                  contributions of cash or other consideration to the
                  Partnership attributable to the General Partner's receipt of
                  cash or other consideration upon the exercise of the Rights by
                  the shareholders of the General Partner pursuant to the Rights
                  Agreement, the General Partner shall be issued a number of
                  Partnership Units as a result of such contribution equal to
                  the number of shares sold pursuant to such exercise. In such
                  event, the Limited Partners shall have the right to purchase
                  additional Partnership Units pursuant to Section 6.4(f).

         E. The Partnership Agreement is hereby amended by adding a new Section
6.4(f) to read as follows:

                   (f) ISSUANCE OF ADDITIONAL UNITS TO THE LIMITED PARTNERS. In
         the event that the holders of stock of the General Partners are issued
         stock for cash or other consideration pursuant to the Rights Agreement
         and the General Partner contributes such cash or other consideration to
         the Partnership pursuant to Section 6.3A, then, without further action
         or consent by the General Partner or any Limited Partner, each Limited
         Partner holding a class of Partnership Units that is convertible into
         such


6

<PAGE>


         stock shall have the right to acquire additional Partnership Units on
         the same terms and conditions as granted to the holders of stock
         pursuant to the Rights Agreement, as if the Limited Partner had
         converted its Partnership Units into stock immediately prior to the
         exercise of the Rights.

         G. The second sentence of Section 7.4(d) of the Partnership
Agreement is amended to add the phrase "or will have" immediately after the
word "has" and immediately before the word "received".

         H. Section 10.3(e) is amended to delete the reference to "Section
10.3(i)" at the end of the first sentence and replaces it with "Section
10.3(j)".

         I. Section 10.3(j)(v) of the Partnership Agreement is hereby amended
to delete the reference to "Section 10.3(i)(iv)" in the parenthetical clause
and replace it with "Sections 6.4(c) and 10.3(j)(iv)"; and the reference in
Section 10.3(j)(vi) to "Section 10.3(i)" is hereby deleted and is replaced
with "Section 10.3(j)".

         Section 3 - MISCELLANEOUS

         A. EFFECT OF AMENDMENT. Except as specifically modified hereby, all
terms and provisions of the Partnership Agreement shall continue to remain in
full force and effect and, except as the context otherwise requires, each
reference to the Partnership Agreement in this Amendment shall be a reference to
the Partnership Agreement as amended hereby.

         B. SUCCESSORS AND ASSIGNS. This Amendment shall inure to the benefit of
and be binding upon the successors and assigns of each of the Partners.

         C. HEADING. The headings in this Amendment are for convenience of

         E. SEVERABILITY. In the event that any one or more of the provisions

MACK-CALI REALTY CORPORATION ADOPTS SHAREHOLDER RIGHTS PLAN

CRANFORD, NJ, - July 2, 1999-Mack-Cali Realty Corporation (NYSE:CLI) announced
today that its Board of Directors has adopted a Shareholder Rights Plan in order
to continue to act in the best interests of the Company and its shareholders if
any hostile takeover activity should occur. The Company's adoption of the Rights
Plan was not taken in response to any known effort to acquire control of the
Company.

Over 3,000 companies have adopted shareholder rights plans, including over
two-thirds of all S&P 500 companies and one-third of publicly traded real estate
investment trusts.

"The shareholder rights plan we have put in place reinforces our commitment to
strong corporate governance and brings us in line with similar measures taken by
the business world's leading companies," commented Mitchell E. Hersh, chief
executive officer. Hersh added, "We believe this action represents a prudent
step towards protecting the investment of our shareholders and preserving the
long-term value of the Company."

To implement the Rights Plan, the Board has declared a distribution of one
right for each outstanding share of common stock to shareholders of record at
the close of business on July 6, 1999. The initial distribution of rights is
not taxable to shareholders. Each right entitles the holder to purchase

<PAGE>

from the Company 1/1000th of a share of Series A junior participating
preferred stock at a purchase price of $100 per right, subject to adjustment.
The rights will expire on July 6, 2009, unless redeemed by the Company as
described below.

At the time of the adoption of the Rights Plan, the rights will not be
exercisable and will trade with the Company's common shares. The rights will
become exercisable if a person or group becomes the beneficial owner of 15%
or more of the then-outstanding common shares of the Company or announces an
offer to acquire 15% or more of the Company's then-outstanding common shares.

If a person or group acquires 15% or more of the Company's outstanding common
shares, then each right not owned by the acquiring person or its affiliates will
entitle its holder to purchase, at the right's then-current exercise price, the
number of common shares of the Company having a market value equal to twice the
then-current exercise price. The plan also provides that if, after the rights
become exercisable, the Company is acquired in a merger or other business
combination transaction with an acquiring person or its affiliates or sells 50%
or more of its assets or earnings power to an acquiring person or its
affiliates, each right will entitle its holder to purchase, at the right's
then-current exercise price, a number of the acquiring company's common shares
having a market value of twice the right's exercise price.

Mack-Cali will be entitled to redeem the rights at $.01 per right at any time
until the tenth day following the public announcement of the acquisition by a
person or group of 15% of the Company's common shares. The Rights Plan further
provides that the Company may, at its option, after a person or group has
acquired ownership of 15% or more of the Company's shares, exchange all or part
of the rights (other than the rights held by the acquiror) for shares of
beneficial interest of the Company at an exchange ratio of one share per right.

A summary of the Rights Plan will be mailed to all common shareholders of record
following the record date.
