                                PROXY STATEMENT

GENERAL INFORMATION

    This Proxy Statement is furnished to stockholders of Mack-Cali Realty
Corporation, a Maryland corporation (the "Company"), in connection with the
solicitation by the Board of Directors of the Company (the "Board of Directors")
of proxies in the accompanying form for use in voting at the Annual Meeting of
Stockholders of the Company (the "Annual Meeting") to be held on Monday,
September 11, 2000, at 3:00 p.m., local time, at the Marriott at Glenpointe,
100 Frank W. Burr Boulevard, Teaneck, New Jersey 07666, and any adjournment or
postponement thereof.

REVOCABILITY OF PROXIES

    Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is exercised by delivering to the Company (to
the attention of Roger W. Thomas, the Company's Secretary) a written notice of
revocation or a properly executed proxy bearing a later date, or by attending
the Annual Meeting and giving notice of your intention to vote in person.

SOLICITATION AND VOTING PROCEDURES

    The solicitation of proxies will be conducted by mail, and the Company will
bear all attendant costs. These costs will include the expense of preparing and
mailing proxy materials for the Annual Meeting and reimbursements paid to
brokerage firms and others for their expenses incurred in forwarding
solicitation material regarding the Annual Meeting to beneficial owners of the
Company's common stock, par value $.01 per share (the "Common Stock"). The
Company may use the services of MacKenzie Partners, Inc., 156 Fifth Avenue,
Suite 110, New York, New York 10010, in soliciting proxies and, in such event,
the Company expects to pay an amount not to exceed $10,000, plus out-of-pocket
expenses, for such services. The Company may conduct further solicitation
personally, telephonically or by facsimile through its officers, directors and
regular employees, none of whom would receive additional compensation for
assisting with the solicitation.

    The presence at the Annual Meeting of a majority of the outstanding shares
of Common Stock of the Company, represented either in person or by proxy, will
constitute a quorum for the transaction of business at the Annual Meeting. The
close of business on July 24, 2000 has been fixed as the record date (the
"Record Date") for determining the holders of shares of Common Stock entitled to
notice of and to vote at the Annual Meeting. Each share of Common Stock
outstanding on the Record Date is entitled to one vote on all matters. As of the
Record Date, there were 58,781,338 shares of Common Stock outstanding. Under
Maryland law, stockholders will not have appraisal or similar rights in
connection with any proposal set forth in this Proxy Statement.

    Stockholder votes will be tabulated by the persons appointed by the Board of
Directors to act as inspectors of election for the Annual Meeting. The New York
Stock Exchange (the "NYSE") permits member organizations to give proxies,
whether or not instructions have been received from beneficial owners, to vote
as to the election of directors and also on matters of the type contained in
Proposal Nos. 2, 3 and 4. Shares represented by a properly executed and
delivered proxy will be voted at the Annual Meeting and, when instructions have
been given by the stockholder, will be voted in accordance with those
instructions. If no instructions are given, the shares will be voted FOR the
election of each of the five nominees for director named below and FOR Proposal
Nos. 2, 3 and 4. Abstentions will have the same effect as a negative vote on
Proposal Nos. 3 and 4 (unless, with respect to Proposal Nos. 3 and 4, the total
votes cast represent more than 50% in interest of all securities entitled to
vote on such proposal, in which
<PAGE>
event an abstention will not have any effect on the result of the vote) but will
have no effect on the outcome of the election of directors or Proposal No. 2.
Broker non-votes will have no effect on the outcome of the election of directors
or Proposal No. 2, but will have the same effect as negative vote on Proposal
Nos. 3 and 4 (unless, with respect to Proposal Nos. 3 and 4, the total votes
cast represent more than 50% in interest of all securities entitled to vote on
such proposal, in which event a broker non-vote will not have any effect on the
result of the vote). Abstentions and broker non-votes will each be counted as
present for purposes of determining the presence of a quorum.

                    VOTING SECURITIES AND PRINCIPAL HOLDERS

    The following table sets forth information as of June 30, 2000, with respect
to each person or group who is known by the Company, in reliance on Schedules
13D and 13G filed with the Securities and Exchange Commission (the "SEC"), to

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    Certain directors and executive officers of the Company (or members of their
immediate families or related trusts) and persons who hold more than 5% of the
outstanding shares of Common Stock (or Units in the Operating Partnership) had
direct or indirect interests in certain transactions of the Company or the
Operating Partnership in the last fiscal year as follows:

    - In connection with the completion of the Mack transaction in
      December 1997 (the "Mack Transaction"), 2,006,432 contingent common Units,
      11,895 Series A contingent preferred Units and 7,799 Series B contingent
      preferred Units were issued as contingent non-participating Units. Such
      contingent Units have no voting, distribution or other rights until such
      time as they are redeemed into common Units, Series A preferred Units and
      Series B preferred Units, respectively. Redemption of such contingent
      Units shall occur upon the achievement of certain performance goals
      relating to certain of the properties acquired by the Company in
      connection with the Mack Transaction (collectively, the "Mack
      Properties"), specifically the achievement of certain leasing activity.
      When contingent Units are redeemed for common and preferred Units, an
      adjustment to the purchase price of certain of the Mack Properties is
      recorded, based on the value of the Units issued. Since certain of the
      performance goals were achieved during 1999, the Company redeemed 275,046
      contingent common Units and issued an equivalent number of common Units.
      There were no contingent preferred Units or contingent common Units
      outstanding as of December 31, 1999. In addition, in connection with the
      Mack Transaction, the Company contractually agreed for a specified period
      of time not to sell or otherwise transfer the properties acquired thereby
      in a manner that would adversely affect the tax deferral of certain
      principals of the Mack organization, subject to certain exceptions set
      forth in the relevant acquisition agreements.

    - In March 1999, the Company acquired two office buildings from Pacifica
      Holding Company ("Pacifica") as part of the third phase of the portfolio
      acquisition of Pacifica (the "Pacifica III Acquisition"), the first two
      phases of which (the "Pacifica I Acquisition" and the "Pacifica II
      Acquisition," respectively) occurred in 1998. The Pacifica III Acquisition
      was comprised of an aggregate of approximately 94,737 square feet and was
      acquired for a total cost of approximately

                                       11
<PAGE>
      $5.7 million. Such funds were made available from drawing on one of the
      Company's credit facilities. William L. Mack, Chairman of the Board of
      Directors and an equity holder of the Company, was an indirect owner of an
      interest in certain of the buildings contained in the Pacifica portfolio,
      through his position as a managing partner of Apollo Real Estate
      Investment Fund II, L.P. ("Apollo"), one of the sellers in the Pacifica
      transaction. 478,783 common Units were issued and approximately
      $13,126,798 in cash was paid in the aggregate to Apollo in the Pacifica I,
      II and III Acquisitions, approximately $5,094,957 of which cash was paid
      upon the achievement of certain performance goals relating to certain of
      the properties acquired from Pacifica, specifically the achievement of
      certain leasing activity. The 478,783 common Units issued to Apollo were
      redeemed by Apollo and converted into 478,783 shares of the Company's
      Common Stock on June 8, 1999.

    - On May 4, 1999, the Company acquired from an entity whose principals
      include Timothy M. Jones, Martin S. Berger and Robert F. Weinberg, who are
      affiliated with the Company as the President of the Company, a current
      member of the Board of Directors and a former member of the Board of
      Directors of the Company, respectively, approximately 2.5 acres of vacant
      land in the Stamford Executive Park, located in Stamford, Fairfield
      County, Connecticut. The Company acquired the land for approximately
      $2,181,000. $1,681,000 of the purchase price was funded from the Company's
      cash reserves with an additional $500,000 due three years from the closing
      date contingent upon certain conditions contained in the acquisition
      contract and subject to interest over the term.

    - On August 31, 1999, the Company acquired from an entity whose principals
      include Brant Cali, who served as Executive Vice President and Chief
      Operating Officer of the Company and a member of the Board of Directors of
      the Company, and certain members of the immediate family of John J. Cali,
      who served as Chairman of the Board of Directors of the Company until
      June 2000, and who currently serves as Chairman Emeritus of the Board of
      Directors of the Company, approximately 28.1 acres of developable land
      adjacent to two of the Company's operating properties located in Roseland,
      Essex County, New Jersey for approximately $6,097,000. The acquisition was
      funded with cash and the issuance of 121,624 common Units to the seller.

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT

    Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's executive officers, directors and
persons who beneficially own more than 10% of the Company's Common Stock to file
initial reports of ownership and reports of changes of ownership (Forms 3, 4 and
5) of the Common Stock with the SEC and the NYSE. Executive officers, directors
and greater than 10% holders are required by SEC regulations to furnish the
Company with copies of such forms that they file.

    To the Company's knowledge, based solely on the Company's review of the
copies of such reports received by the Company, the Company believes that for
the fiscal year 1999, all Section 16(a) filing requirements applicable to its
executive officers, directors and greater than 10% beneficial owners were
complied with.

MEETINGS OF COMMITTEES AND THE BOARD OF DIRECTORS

    During 1999, the entire Board of Directors met 11 times. With the exception
of Irvin D. Reid and Roy J. Zuckerberg, no director attended fewer than 75% of
the aggregate of the total number of meetings of the Board of Directors (held
during the period for which he has been a director) and the total number of
meetings held by all committees of the Board of Directors on which he served
(during the periods that he served).

                                       12
<PAGE>
    The Board of Directors has five committees: the Executive Committee, the
Audit Committee, the Executive Compensation and Option Committee, the Strategic
Planning Committee and the Nominating Committee.

    The Executive Committee consists of William L. Mack, chairman, John R. Cali,
Nathan Gantcher, Mitchell E. Hersh and Roy J. Zuckerberg. The Executive
Committee acts for the Board of Directors in between regularly scheduled
meetings of the Board of Directors within certain parameters prescribed by the
Board of Directors.

    The Audit Committee consists of Irvin D. Reid, chairman, Brendan T. Byrne,
Nathan Gantcher and Roy J. Zuckerberg, each of whom are independent directors of
the Company. The Audit Committee makes recommendations concerning the engagement
of independent accountants, reviews with the independent accountants the scope
and results of the audit engagement, approves professional services provided by
the independent accountants, reviews the independence of the independent
accountants, considers the range of audit and non-audit fees and reviews the
adequacy of the Company's internal accounting controls. The Audit Committee met
twice during 1999. On June 8, 2000, the Board of Directors, upon the unanimous
recommendation of the Audit Committee, approved and adopted the Mack-Cali Realty
Corporation Audit Committee Charter, a copy of which is attached hereto as
Exhibit A.

    The Executive Compensation and Option Committee consists of Vincent Tese,
chairman, Martin D. Gruss and Alan G. Philibosian. The Executive Compensation
and Option Committee establishes remuneration levels for executive officers of
the Company and implements incentive programs, including the Employee Stock
Option Plan and the Director Stock Option Plan. The Executive Compensation and
Option Committee met twice during 1999.

    The Strategic Planning Committee consists of Martin S. Berger, chairman,
John J. Cali, Mitchell E. Hersh, Earle I. Mack and Roy J. Zuckerberg. The
Strategic Planning Committee makes recommendations concerning long range
strategic alternatives for the Company. The Strategic Planning Committee was
formed in January 2000, and therefore did not meet during 1999.

    The Nominating Committee consists of Vincent Tese, chairman, Nathan Gantcher
and Alan G. Philibosian. The Nominating Committee makes recommendations for
nominees to the Board of Directors of the Company. Although there are no formal
procedures for stockholders to make recommendations for committee appointments
or recommendations for nominees to the Board of Directors, the Board of
Directors will consider recommendations from stockholders, which should be
addressed to Roger W. Thomas, the Company's Secretary, at the Company's address
set forth on the first page of this Proxy Statement. The Nominating Committee
was formed in June 2000, and therefore did not meet during 1999.

COMPENSATION OF DIRECTORS

    DIRECTORS' FEES.  Each non-employee director was paid an annual fee of
$15,000, plus $1,000 per board meeting attended, $500 per committee meeting
attended and $250 per telephonic meeting participation. The Company does not pay
director fees to employee directors, who in fiscal 1999 consisted of Mitchell E.
Hersh, Brant Cali and, prior to his resignation, Thomas A. Rizk. Each director
also was reimbursed for expenses incurred in attending director and committee
meetings. For fiscal 1999, John J. Cali, Martin S. Berger, Brendan T. Byrne,
Nathan Gantcher, Martin D. Gruss, Earle I. Mack, William L. Mack, Alan G.
Philibosian, Irvin D. Reid, Vincent Tese and Roy J. Zuckerberg received
directors' fees or fee equivalents (see "Directors' Deferred Compensation Plan"
below) in the amounts of $17,250, $17,250, $17,750, $11,772, $21,500, $16,750,
$21,000, $19,125, $21,000, $19,000 and $11,522, respectively. In addition,
Jeffrey B. Lane and Paul A. Nussbaum, who resigned and declined renomination to
serve as a director of the Company, respectively, on May 19, 1999, received
directors' fees or fee equivalents (see

                                       13
<PAGE>
"Directors' Deferred Compensation Plan" below) in the amounts of $9,269 and
$9,769, respectively, while serving as directors of the Company during fiscal
1999.

    DIRECTORS' DEFERRED COMPENSATION PLAN.  Pursuant to the Directors' Deferred
Compensation Plan, effective as of January 1, 1999, each non-employee director
is entitled to defer all or a specified portion of the annual retainer to be
paid to such director. The account of a director who elects to defer such
compensation under the Directors' Deferred Compensation Plan is credited with
the hypothetical number of stock units, calculated to the nearest thousandths of
a unit, determined by dividing the amount of compensation deferred on the
deferral date by the closing market price of the Company's Common Stock as
reported on the Consolidated Tape of NYSE listed shares on the deferral date.
Any stock dividend declared by the Company on its Common Stock results in a
proportionate increase in units in the director's account as if such director
held shares of Common Stock equal to the number of units in such director's
account. Payment of a director's account may only be made in a lump sum in
shares of Common Stock equal to the number of units in a director's account
after either the director's service on the Board of Directors has terminated or
there has been a change in control of the Company. As of December 31, 1999, the
director accounts of Nathan Gantcher, Martin D. Gruss, William L. Mack, Alan G.
Philibosian, Irvin D. Reid, Vincent Tese and Roy J. Zuckerberg were credited
with 363, 576, 576, 288, 576, 576 and 363 stock units, respectively.

    DIRECTORS' STOCK OPTION PLAN.  Pursuant to the Director Stock Option Plan,
each non-employee director is automatically granted a non-statutory option to
purchase 5,000 shares of Common Stock in connection with the director's initial
election or appointment to the Board of Directors. These grants under the
Director Stock Option Plan are made at an exercise price equal to the "fair
market value" (as defined under the Director Stock Option Plan) at the time of
the grant of the shares of Common Stock subject to such option. The Executive
Compensation and Option Committee may make additional discretionary option
grants to eligible directors, consistent with the terms of the Director Stock
Option Plan. In 1999, 27,000 discretionary options were granted to members of
the Board of Directors. The Board of Directors may amend, suspend or discontinue
the Director Stock Option Plan at any time except that any amendments that would
materially increase the cost of the Director Stock Option Plan to the Company
must be approved by the holders of the majority of issued and outstanding shares
of Common Stock of the Company entitled to vote.

(1) The annual compensation portion of this table includes the dollar value of
    regular annual payments of base salary, bonus and any other annual
    compensation earned by each Named Executive Officer during the stated fiscal
    year. Certain base salaries appear slightly higher than the contractual
    amounts due to when pay periods accrued during fiscal year 1999.

(2) The $2,179 in 1998 represents the value of 10 shares of preferred stock of
    Mack-Cali Property Trust issued in January 1998 and $1,179 in tax gross-up
    payments relating thereto.

(3) Brant Cali resigned as a director of the Company and from his positions as
    Chief Operating Officer, Executive Vice President--Operations, Leasing and
    Marketing and Assistant Secretary of the Company, effective as of June 27,
    2000.

(4) John R. Cali resigned from his position as Executive Vice
    President--Development, effective as of June 27, 2000.

(5) Thomas A. Rizk resigned from his position as Chief Executive Officer of the
    Company, effective as of April 18, 1999.

(6) On August 31, 1994, in connection with the consummation of the Company's
    initial public offering, the Company entered into employment agreements with
    each of Thomas A. Rizk, John R. Cali and Brant Cali. On January 21, 1997,
    the Company entered into amended and restated employment agreements with
    each of Messrs. Rizk, John R. Cali and Brant Cali, and an employment
    agreement with Barry Lefkowitz. Pursuant to each such employment agreement,
    Messrs. Rizk, John R. Cali, Brant Cali and Lefkowitz were issued 55,555,
    55,555, 55,555 and 9,260 restricted shares of Common Stock (the "Restricted
    Stock"), respectively. On the date of any vesting of the Restricted Stock,
    each

<PAGE>
    of Messrs. Rizk, John R. Cali, Brant Cali and Lefkowitz were entitled to
    receive tax gross-up payments as compensation for the additional income
    taxes which would be required to be paid. The employment agreements provided
    that the vesting of the Restricted Stock would be accelerated upon a change
    in control and, in the case of Messrs. Rizk, John R. Cali and Brant Cali,
    upon termination of employment by the Company other than for cause or by
    such individual for good reason. Upon the closing of the Mack Transaction in
    December 1997, certain conditions in the employment agreements of each of
    the aforementioned senior executives were triggered, thereby resulting in,
    among other things, the acceleration of the vesting of the Restricted Stock,
    including the payment of the tax gross-up amounts relating thereto. The
    value of accelerated vesting in Restricted Stock and the tax gross-up
    payments relating thereto under such employment agreement for each executive
    upon consummation of the Mack Transaction, based on a $39.00 stock price,
    which price approximated the market price of the Company's Common Stock at
    the close of business on or about the date of closing of the Mack
    Transaction, is reflected in the table for 1997. In July 1999, the Company
    entered into amended and restated employment agreements with each of
    Mitchell E. Hersh, Timothy M. Jones, Barry Lefkowitz, Brant Cali and John R.
    Cali, pursuant to which, Messrs. Hersh, Jones, Lefkowitz, Brant Cali and
    John R. Cali were issued 62,500, 37,500, 26,094, 23,437 and 22,031 shares of
    Restricted Stock, respectively, the vesting of which is contingent upon the
    satisfaction of certain performance requirements. There are certain tax
    gross-up payments that will be made upon such vesting. Since the Restricted
    Stock granted is performance based with vesting commencing January 1, 2000,
    the Company has elected to report such awards as Long-Term Incentive Plan
    Awards. See "Long-Term Incentive Plans--Awards in Last Fiscal Year." In
    addition, Brant Cali's and John R. Cali's remaining unvested Restricted
    Stock vested in June 2000 pursuant to the Cali Agreement. The 1999 amended
    and restated employment agreements superceded, amended and restated the
    employment agreements between the Company and each of the aforementioned
    executives entered into in December 1997. Pursuant to the Cali Agreement,
    the Amended and Restated B. Cali Agreement and the Amended and Restated J.R.
    Cali Agreement (each as hereinafter defined under "Employment Contracts;
    Termination of Employment") were terminated as of June 27, 2000.

(7) Represents an option to purchase shares of Common Stock at an exercise price
    of $38.75 per share.

(8) Represents an option to purchase shares of Common Stock at an exercise price
    of $37.3125 per share.

(9) Represents an option to purchase 15,000 shares of Common Stock at an
    exercise price of $30.25 per share, an option to purchase 105,295 shares of
    Common Stock at an exercise price of $38.75 per share and warrants to
    purchase 170,000 shares of Common Stock at an exercise price of $33.00 per
    share.

(10) In connection with their respective January 21, 1997 employment agreements,
    the Company made non-recourse stock acquisition loans (the "Stock
    Acquisition Loans") to Messrs. Rizk and Lefkowitz in the amounts of
    $3,000,000 and $500,000, respectively, the proceeds of which were
    simultaneously used by each of Messrs. Rizk and Lefkowitz to purchase 96,000
    and 16,000 shares of Common Stock, respectively, from the Company, pursuant
    to the terms of each loan. The Stock Acquisition Loans (and the interest
    thereon) were to be forgiven under certain terms and conditions. On the date
    of forgiveness of the Stock Acquisition Loans, each of Messrs. Rizk and
    Lefkowitz were entitled to receive tax gross-up payments as compensation for
    the additional income taxes which would be required to be paid. Such
    employment agreements provided that the forgiveness of the Stock Acquisition
    Loans would be accelerated upon a change in control and, in the case of
    Mr. Rizk, upon termination of his employment by the Company other than for
    cause or by him for good reason. Upon the closing of the Mack Transaction in
    December 1997, certain conditions in the employment agreements of each of
    the aforementioned senior executives were triggered, thereby resulting in,
    among other things, the acceleration of the forgiveness of the Stock
    Acquisition Loans, including interest thereon, and the payment of the tax
    gross-up amounts relating thereto. The value of the accelerated Stock
    Acquisition Loan forgiveness and the interest and tax gross-up payments
    relating

                                       17
<PAGE>
    thereto determined to be payable to each executive upon consummation of the
    Mack Transaction is reflected in the table for 1997.

(11) Under each of Messrs. Rizk's, Brant Cali's and John R. Cali's January 1997
    employment agreements with the Company, each executive was entitled under
    certain circumstances to receive certain severance payments in the event he
    terminated his employment with the Company for good reason. Furthermore,
    upon a resignation for good reason, each such executive could immediately
    compete directly with the Company. In light of the significant changes in
    the overall authority, duties and responsibilities of these individuals
    resulting from the Mack Transaction, the Executive Compensation and Option
    Committee determined and the Board of Directors of the Company concurred
    that consummation of the Mack Transaction would have entitled each of these
    senior executives to terminate his employment for good reason, receive such
    payments and thereafter not be subject to the non-competition provisions of
    his employment agreement. However, the Executive Compensation and Option
    Committee and the Board of Directors concluded that the continued employment
    of and lack of competition by these senior executives is essential to the
    continued success of the Company's business and in the best interests of the
    Company and its stockholders. Therefore, the Board of Directors, in its
    discretion, authorized the Company to enter into new employment agreements
    with these senior executives, effective upon the consummation of the Mack
    Transaction, pursuant to which, among other things, the senior executives
    were paid the amounts referenced in the table in cancellation of their
    January 21, 1997 employment agreements and for the re-affirmation of their
    agreements not to compete directly with the Company. Each of these senior
    executives on December 11, 1997 entered into a new employment agreement with
    the Company pursuant to which each of the senior executives waived any right
    he may have had to sever employment and to compete with the Company as a
    result of the Mack Transaction. These agreements were superceded in the case
    of Messrs. John R. Cali and Brant Cali by new employment agreements dated
    July 1, 1999. Pursuant to the Cali Agreement, the Amended and Restated B.
    Cali Agreement and the Amended and Restated J.R. Cali Agreement (each as
    hereinafter defined under "Employment Contracts; Termination of Employment")
    were terminated as of June 27, 2000. For a description of the existing
    employment agreements see "Employment Contracts; Termination of Employment."

(12) Includes payments made to Thomas A. Rizk in connection with his resignation
    as Chief Executive Officer of the Company, effective as of April 18, 1999.
    See "Employment Contracts; Termination of Employment--Thomas A. Rizk
    Termination Agreement."

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

(1) In July 1999, the Company entered into amended and restated employment
    agreements with each of Mitchell E. Hersh, Timothy M. Jones, Barry
    Lefkowitz, Brant Cali and John R. Cali, pursuant to which Messrs. Hersh,
    Jones, Lefkowitz, Brant Cali and John R. Cali were issued 62,500, 37,500,
    26,094, 23,437 and 22,031 shares of Restricted Stock, respectively, the
    vesting of which is contingent upon the satisfaction of certain performance
    requirements. There are certain tax gross-up payments that will be made upon
    such vesting. See "Employment Contracts; Termination of Employment." The
    shares of Restricted Stock vest with respect to the recipient on either an
    annual basis over a five year vesting period or on a cumulative basis over a
    seven year maximum vesting period. The number of shares of Restricted Stock
    scheduled to be vested and earned on each vesting date on an annual basis,
    provided certain performance requirements set forth in the following
    sentence are satisfied, generally is equal to 15% of the Restricted Stock on
    the vesting date in year one, 15% of the Restricted Stock on the vesting
    date in year two, 20% of the Restricted Stock on the vesting date in year
    three, 25% of the Restricted Stock on the vesting date in year four and 25%
    of the Restricted Stock on the vesting date in year five. Vesting of the
    Restricted Stock on an annual basis commences January 1, 2000, provided one
    of the following financial tests is met for the measurement period ending on
    the last day of the Company's fiscal year immediately preceding such vesting
    date: (A) the Company achieves an eight percent (8%) increase in its funds
    from operations per common share or (B) stockholders achieve a twelve and
    three quarters percent (12.75%) total return (dividends, assuming
    reinvestment upon applicable payment date, plus stock appreciation per share
    of Common Stock). The Company met the first of such tests for the
    measurement period ended December 31, 1999. Pursuant to the Cali Agreement,
    the unvested Restricted Stock awarded to Brant Cali and John R. Cali vested
    in June 2000.

EMPLOYMENT CONTRACTS; TERMINATION OF EMPLOYMENT

    MITCHELL E. HERSH EMPLOYMENT AGREEMENT.  On July 1, 1999, following the
appointment of Mitchell E. Hersh as Chief Executive Officer of the Company on
April 18, 1999, the Company and Mr. Hersh amended and restated Mr. Hersh's
employment agreement with the Company (the "Amended and Restated Hersh
Agreement"), providing for a constant 4 year term. Mr. Hersh's initial annual
base salary is $1,050,000, with annual increases within the discretion of the
Executive Compensation and Option Committee. Mr. Hersh also is eligible to
receive an annual bonus, restricted share awards and options within the
discretion of the Board of Directors or the Executive Compensation and Option
Committee, as the case may be. Pursuant to the Employee Stock Option Plan,
Mr. Hersh was awarded 62,500 shares of Restricted Stock as of July 1, 1999, and
with respect to each tax year in which such shares of Restricted Stock vest and
are distributed to him, Mr. Hersh shall be entitled to receive a tax gross-up
payment from the Company equal to forty-three percent (43%) of the fair market
value of such restricted shares at the time of vesting, exclusive of dividends
(the "Tax Gross-Up Payments"). Mr. Hersh is required to devote substantially all
of his business time to the affairs of the Company and, subject to certain
excluded activities, generally is restricted during the term of his employment
and in the event his employment is terminated by the Company for cause (as
defined in the Amended and Restated Hersh Agreement) or by him without good
reason (as defined in the Amended and Restated Hersh Agreement), for a period of
one year thereafter, from conducting any office-service, flex or office property
development, acquisition or management activities within the continental United
States. Mr. Hersh is entitled to (i) receive the aggregate of a cash payment of
$8,000,000 (the "Fixed Amount"), reimbursement of expenses incurred prior to the
date of termination, and the Tax-Gross-Up Payments applicable to any vested
shares of Restricted Stock, (ii) immediate vesting of all options and incentive
compensation payments or programs otherwise subject to a vesting schedule,
(iii) require the Company to repurchase his vested options and (iv) receive
continuation of health coverage through the end of his unexpired employment
period should his employment be terminated by the Company without cause, by him
for good reason or on account of his disability (as defined in the Amended and
Restated Hersh Agreement) or death. Should Mr. Hersh terminate his employment on
or within six months following a change in control (as defined in the Amended
and Restated Hersh Agreement), Mr. Hersh's termination shall be treated as a
termination for good reason. In addition, upon a change in control, the vesting
of all options and other incentive compensation shall be accelerated and
Mr. Hersh would be entitled to receive a tax gross-up payment to cover any
excise taxes payable due to the change in control.

(the "Amended and Restated B. Cali Agreement"). The other terms and conditions

annual base salary is $345,000, (ii) Mr. Cali was awarded 23,437 shares of
Restricted Stock and (iii) the Fixed Amount Mr. Cali will receive is $2,500,000.

    THOMAS A. RIZK TERMINATION OF EMPLOYMENT AGREEMENT.  On April 18, 1999, the
Company and Thomas A. Rizk entered into an agreement (the "Rizk Termination
Agreement") to, among other things, terminate Mr. Rizk's employment with the
Company as Chief Executive Officer and his position as a member of the Board of
Directors of the Company and a member of the Executive Committee of the Board of
Directors. Pursuant to the terms and conditions of the Rizk Termination
Agreement, all of Mr. Rizk's options were canceled, and the Company agreed to
pay Mr. Rizk $18,525,000, reduced by $2,535,000 as required by a settlement
agreement entered in the Circuit Court for Baltimore City, of which $14,490,000,
less applicable taxes, was paid upon execution of the Rizk Termination Agreement
and the remainder of which was placed in a "Rabbi Trust" so that on each of
April 20, 2000, 2001 and 2002, the trustee shall make payments from the Rabbi
Trust to Mr. Rizk in the amount of $500,000, less applicable taxes. In addition,
in accordance with the terms and conditions of the Rizk Termination Agreement,
the Company converted Mr. Rizk's 141,383 Units into 141,383 shares of Common
Stock. At the date of the Rizk Termination Agreement, Mr. Rizk held 151,555
vested shares of Restricted Stock. In April 1999, subsequent to the termination
of his employment with the Company, Mr. Rizk sold all 292,938 shares in various
transactions, most of which was sold in a block sale at a price of $29.50 per
share.

    CALI AGREEMENT.  Pursuant to the Cali Agreement, effective in June 2000,
both Brant Cali and John R. Cali resigned their positions as officers of the
Company, and Brant Cali resigned as a director of the Company. As required by
the Amended and Restated B. Cali Agreement and the Amended and Restated J.R.
Cali Agreement, respectively, under the Cali Agreement, (i) the Company made
severance payments to Brant Cali and John R. Cali in the amount of $2,820,156
and $2,805,576, respectively, (ii) the Company will permit Brant Cali and John
R. Cali (and their dependents) to participate in the health and disability
insurance programs of the Company for a period of four years and (iii) all
options to acquire shares of the Company's Common Stock and shares of Restricted
Stock held by Brant Cali and John R. Cali became fully vested on the effective
dates of their resignations from the Company. Pursuant to the Cali Agreement,
Brant Cali and John R. Cali will remain bound by the non-compete provisions of
the Amended and Restated B. Cali Agreement and the Amended and Restated J.R.
Cali Agreement, respectively, until December 27, 2000.

    Pursuant to the Cali Agreement, the Company has agreed to nominate John J.
Cali and John R. Cali for election as directors at the Annual Meeting. If either
John J. Cali or John R. Cali refuse to stand for

                                       22
<PAGE>
election or fail to be elected to the Board of Directors, or resign or are
removed from the Board of Directors during their term, the members of the Cali
family are entitled to designate a successor to John J. Cali, John R. Cali, or
both. Any such successor will be subject to the prior approval of the Board of
Directors, which approval shall not be unreasonably withheld. In addition, for
as long as members of the Cali family (or entities wholly owned by the Cali
family, Cali family trusts or the heirs of any member of the Cali Group (as
defined in the Cali Agreement)) maintain at least the "Minimum Percentage" (as
defined below) of the Cali family's aggregate equity position in the Units in
the Operating Partnership (measured exactly as it existed on June 27, 2000), the
Company has agreed to nominate one designee of the Cali family for election to
the Board of Directors for a second and third three-year term, provided such
person shall be subject to the prior approval of the Board of Directors, which
approval shall not be unreasonably withheld. Accordingly, the members of the
Cali family who are parties to the Cali Agreement (who in the aggregate are the
beneficial owners of 3.24% of the outstanding common stock of the Company,
calculated on a fully-diluted basis) have a substantial interest in the election
of John J. Cali and John R. Cali to the Board of Directors. For purposes of the
Cali Agreement, "Minimum Percentage" shall mean (i) 90% or (ii) 87.5%, if the
Cali family's aggregate equity position in the Units in the Operating
Partnership is reduced below 90% solely as a result of sales of Units to the
Company.

    For as long as (i) the Cali family is represented on the Board of Directors,
(ii) the Cali family (or entities wholly owned by the Cali family, Cali family
trusts, or the heirs of any member of the Cali Group) maintains at least the
Minimum Percentage of the Cali family's aggregate equity position in the Units
of the Operating Partnership (measured exactly as it existed on June 27, 2000)
and (iii) the Board of Directors determines in its reasonable discretion to
continue the Executive Committee of the Board of Directors, the Cali family
shall be entitled to designate John R. Cali or another Cali-designated board
member to serve as a member of the Executive Committee of the Board of
Directors, provided such person shall be subject to the prior approval of the
Board of Directors, which approval may not be unreasonably withheld.

    Pursuant to the Cali Agreement, members of the Cali Group were granted
certain limited tax protection with respect to the properties that they
initially contributed to the Company upon its formation. Such limited tax
protection is similar to that which was granted to members of the Mack Group
with respect to the properties that they contributed to the Company. Pursuant to
the Cali Agreement, John J. Cali will serve as a consultant to the Company for
three years and will be paid an annual salary of $150,000.

EXECUTIVE COMPENSATION AND OPTION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    There are no interlocking relationships involving the Company's Board of
Directors which require disclosure under the executive compensation rules of the
SEC.

BOARD EXECUTIVE COMPENSATION AND OPTION COMMITTEE REPORT ON EXECUTIVE
COMPENSATION

    Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities Act of 1933, as amended, or the Exchange
Act that might incorporate future filings, including this Proxy Statement, in
whole or in part, the following report and the Performance Graph which follows
shall not be deemed to be incorporated by reference into any such filings.

    EXECUTIVE COMPENSATION PHILOSOPHY.  The Executive Compensation and Option
Committee will annually consider the appropriate combination of cash and
option-based compensation and weigh the competitiveness of the Company's overall
compensation arrangements in relation to comparable real estate investment
trusts. From time to time the Executive Compensation and Option Committee may
retain compensation and other management consultants to assist with, among other
things, structuring the Company's various compensation programs and determining
appropriate levels of salary, bonus and other compensatory awards payable to the
Company's executive officers and key employees, as well as to guide

                                       23
<PAGE>
the Company in the development of near-term and long-term individual performance
objectives necessary to achieve long-term profitability.

    The Executive Compensation and Option Committee believes that a fundamental
goal of the Company's executive compensation program should be to provide
incentives to create value for the Company's stockholders.

    BASE SALARIES.  The base compensation levels for the Company's executive
officers in 1999 were set to compensate the executive officers for the functions
they will perform as well as to be consideration for certain non-competition
provisions in the agreements, and were based on the employment agreements
entered into in December 1997, as amended and restated in July 1999. The Company
believes that the base salaries generally are appropriate as base compensation
to compensate the Company's executive officers for the functions they perform
and other considerations. Base salaries will be reviewed annually and may be
increased by the Executive Compensation and Option Committee or the Chief
Executive Officer, as the case may be, in accordance with certain criteria
determined primarily on the basis of growth of revenues and funds from
operations per share of Common Stock and on the basis of certain other factors,
which include (i) individual performance, (ii) the functions performed by the
executive officer and (iii) changes in the compensation peer group in which the
Company competes for executive talent. The weight given such factors by the
Executive Compensation and Option Committee may vary from individual to
individual.

    ANNUAL BONUS COMPENSATION.  The Company's policy of awarding annual cash
bonuses is designed to specifically relate executive pay to Company and
individual performance. As a pay-for-performance program, cash bonuses provide
financial rewards for the achievement of substantive Company and personal
objectives. Actual awards paid are based primarily on actual Company
performance. During 1999, discretionary incentive and merit cash bonuses in
recognition of services performed during fiscal 1999 were awarded as follows:
$440,000 to Mitchell E. Hersh, $275,000 to Timothy M. Jones, $225,000 to Barry
Lefkowitz, $185,000 to Brant Cali, $185,000 to John R. Cali and $185,000 to
Roger W. Thomas.

    EMPLOYEE STOCK OPTION PLAN.  Awards are granted under the Employee Stock
Option Plan based on a number of factors, including (i) the executive officer's
or key employee's position in the Company, (ii) his or her performance and
responsibilities, (iii) the extent to which he or she already holds an equity
stake in the Company, (iv) equity participation levels of comparable executives
and key employees at other companies in the compensation peer group and
(v) individual contribution to the success of the Company's financial
performance. However, the Employee Stock Option Plan does not provide any
formulated method for weighing these factors, and a decision to grant an award
is based primarily upon the Executive Compensation and Option Committee's
evaluation of the past as well as the future anticipated performance and
responsibilities of the individual in question. During 1999, performance based
restricted share awards were granted to Mitchell E. Hersh (62,500), Timothy M.
Jones (37,500), Barry Lefkowitz (26,094), Brant Cali (23,437), John R. Cali
(22,031) and Roger W. Thomas (22,031), subject to a multi-year vesting schedule.
No options or other stock based awards were granted to executive officers of the
Company.

    The Company's Employee Stock Option Plan relates closely to traditional
forms of equity oriented compensation in the commercial real estate industry.
The purpose of the option and other stock based grants is to aid the Company in
attracting and retaining quality employees, all advancing the interest of the
Company's stockholders by offering employees an incentive to maximize their
efforts to promote the Company's economic performance. In addition, to assist
the Company in retaining employees and encouraging them to seek long-term
appreciation in the value of the Company's stock, awards generally are not
exercisable immediately upon grant, but instead vest over a period of years.
Accordingly, an employee must remain with the Company for a period of years to
enjoy the full economic benefit of an award.

    401(K) SAVINGS PLAN.  The Company also maintains a tax-qualified 401(k)
savings plan for its eligible employees known as the "Mack-Cali Realty
Corporation 401(k) Savings/Retirement Plan" ("401(k)

                                       24
<PAGE>
Plan"). Employees who have attained age 21 and completed one-half year of
service with the Company are eligible to participate and may elect to defer up
to 15% of their base pay on a pre-tax basis to the 401(k) Plan. The Company may
make discretionary matching or profit sharing contributions to the 401(k) Plan
on behalf of eligible participants in any plan year. Participants are always
100% vested in their pre-tax contributions and will begin vesting in any
matching or profit sharing contributions made on their behalf after two years of
service with the Company at a rate of 20% per year becoming 100% vested after a
total of six years of service with the Company. The assets of the 401(k) Plan
are held in trust and a separate account is established for each participant. A
participant may receive a distribution of his vested account balance in the
401(k) Plan in a single sum or installment payment or in the form of an annuity
upon his termination of service with the Company.

    CHIEF EXECUTIVE OFFICER COMPENSATION.  Mitchell E. Hersh, the Chief
Executive Officer of the Company, received a base salary during 1999 of
$1,050,000 pursuant to the employment agreement entered into in December 1997,
as amended and restated in July 1999. Mr. Hersh also was paid a cash bonus of
$440,000 in recognition of services performed during fiscal 1999. Mr. Hersh
received no fees for his service as a Director of the Company during fiscal
1999. During 1999, Mr. Hersh was granted 62,500 performance based restricted
share awards, subject to a multi-year vesting schedule. The Executive
Compensation and Option Committee recognizes Mr. Hersh's contributions to the
Company's operations and attempts to ensure that the Chief Executive Officer's
compensation is commensurate with the compensation of chief executive officers
of comparable corporations. The Board of Directors deemed such bonus and
Mr. Hersh's total compensation appropriate in light of Mr. Hersh's substantial
contribution to the Company's growth and success in 1999.

                                 PROPOSAL NO. 2

             RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS

    PricewaterhouseCoopers LLP served as the Company's independent accountants
for the fiscal year ended December 31, 1999, and has been appointed by the Board
of Directors to continue as the Company's independent accountants for the fiscal
year ending December 31, 2000. In the event that ratification of this
appointment of auditors is not approved by the affirmative vote of a majority of
votes cast on the matter, then the appointment of independent accountants will
be reconsidered by the Board of Directors. Unless marked to the contrary,
proxies received will be voted for RATIFICATION OF THE APPOINTMENT OF
PRICEWATERHOUSECOOPERS LLP AS THE COMPANY'S INDEPENDENT ACCOUNTANTS FOR THE
FISCAL YEAR ENDING DECEMBER 31, 2000.

    A representative of PricewaterhouseCoopers LLP is expected to be present at
the annual meeting. The representative will have an opportunity to make a
statement and will be able to respond to appropriate questions.

    Your ratification of the appointment of PricewaterhouseCoopers LLP as the
Company's independent accountants for the fiscal year ending December 31, 2000
does not preclude the Board of Directors of the Company from terminating its
engagement of PricewaterhouseCoopers and retaining a new independent accountant,
if it determines that such an action would be in the best interests of the
Company. If the Company elects to retain a new independent accountant, such
accountant will be another "Big 5" accounting firm.

VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION

    Assuming a quorum is present, the affirmative vote of a majority of the
votes cast at the Annual Meeting, either in person or by proxy, is required for
approval of this proposal. Abstentions and broker non-votes will have no effect
on the outcome of this proposal.

    THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THE APPOINTMENT
OF PRICEWATERHOUSECOOPERS LLP AS THE COMPANY'S INDEPENDENT ACCOUNTANTS FOR THE
FISCAL YEAR ENDING DECEMBER 31, 2000.

                                 PROPOSAL NO. 3

        APPROVAL OF THE ADOPTION OF THE 2000 EMPLOYEE STOCK OPTION PLAN.

    At its meeting on June 27, 2000, the Board of Directors of the Company
adopted the 2000 Employee Stock Option Plan (the "2000 Employee Stock Option
Plan") (a copy of which is attached hereto as Exhibit B) and directed that the
2000 Employee Stock Option Plan be submitted to the stockholders for their
approval. The Board of Directors believes that adoption of the 2000 Employee
Stock Option Plan is in the best interests of the Company and its stockholders
because the ability to grant stock options and make other stock-based awards
under the 2000 Employee Stock Option Plan is an important factor in attracting,
motivating and retaining qualified personnel essential to the success of the
Company.

    SUMMARY OF THE PROVISIONS OF THE 2000 EMPLOYEE STOCK OPTION PLAN.

    The following summary of the 2000 Employee Stock Option Plan is qualified in
its entirety by the specific language of the plan, a copy of which is attached
hereto as Exhibit B.

    GENERAL.  The purposes of the 2000 Employee Stock Option Plan are to attract
and retain the best personnel for positions of substantial responsibility and to
provide additional incentives to key employees, officers, consultants and other
persons whose efforts are deemed worthy of encouragement to promote the growth
and success of the Company. The 2000 Employee Stock Option Plan provides for the
grant of incentive stock options, within the meaning of Section 422 of the Code
to employees of the Company and for the grant of nonstatutory stock options,
stock appreciation rights ("SARs") and Restricted Stock to employees,
consultants and advisors of the Company. The Board of Directors has authorized,
subject to stockholder approval, 2,500,000 shares of Common Stock for issuance
under the 2000 Employee Stock Option Plan. In the event of any stock dividend,
recapitalization, reorganization, merger, consolidation, split-up, exchange of
shares, combination, or like change in the capital structure of the Company,
appropriate adjustments will be made to the shares subject to the 2000 Employee
Stock Option Plan and to any outstanding awards. To the extent any outstanding
option under the 2000 Employee Stock Option Plan expires or terminates prior to
its exercise in full, or if any shares of Restricted Stock or SARs are
forfeited, the shares of Common Stock no longer subject to the option, SARs or
restrictions will be returned to the 2000 Employee Stock Option Plan and made
available for future grants.

    ADMINISTRATION.  The 2000 Employee Stock Option Plan is administered by the
Executive Compensation and Option Committee of the Board of Directors of the
Company. With respect to the participation of individuals who are subject to
Section 16 of the Exchange Act, the 2000 Employee Stock Option Plan is
administered in compliance with the requirements of Rule 16b-3 under the
Exchange Act. Subject to the provisions of the 2000 Employee Stock Option Plan,
the Executive Compensation and Option Committee determines the persons to whom
grants of options, SARs, and shares of Restricted Stock are to be made, the
number of shares of Common Stock to be covered by each grant and all other terms
and conditions of the grant. If an option is granted, the Executive Compensation
and Option Committee determines whether the option is an incentive stock option
or a nonstatutory stock option, the option's term, vesting and exercisability,
the amount and type of consideration to be paid to the Company upon the option's
exercise and the other terms and conditions of the grant. The terms and
conditions of Restricted Stock and SAR awards are also determined by the
Executive Compensation and Option Committee. The Executive Compensation and
Option Committee has the responsibility to interpret the 2000 Employee Stock
Option Plan and to make determinations with respect to all awards granted under
the 2000 Employee Stock Option Plan. All determinations of the Executive
Compensation and Option Committee are final and binding on all persons having an
interest in the 2000 Employee Stock Option Plan or in any award made under the
2000 Employee Stock Option Plan. The costs and expenses of administering the
2000 Employee Stock Option Plan are borne by the Company.

                                       28
<PAGE>
    ELIGIBILITY.  All employees, consultants and advisors who in the judgment of
the Executive Compensation and Option Committee, are considered important to the
future of the Company (including officers and directors of the Company who are
also employees) are eligible to participate in the 2000 Employee Stock Option
Plan. Non-employee directors of the Company may not participate.

    TERMS AND CONDITIONS OF OPTION GRANTS.  Each option granted under the 2000
Employee Stock Option Plan is evidenced by a written agreement between the
Company and the optionee specifying the number of shares of the Company's Common
Stock subject to the option and all of the other terms and conditions of the
option, consistent with the requirements of the 2000 Employee Stock Option Plan.
The per share exercise price of an incentive stock option may not be less than
100% of the fair market value of a share of Common Stock on the date of the
option's grant and the term of any such option shall expire on the tenth
anniversary of the date of the option's grant. In addition, the per share
exercise price of any option granted to a person who at the time of the grant
owns stock possessing more than 10% of the total combined voting power or value
of all classes of stock of the Company must be at least 110% of the fair market
value of a share of the Company's Common Stock on the date of grant (but in no
event less than the par value of a share) and such option shall expire on the
fifth anniversary of the date of the option's grant. After the Company grants an
option pursuant to the 2000 Employee Stock Option Plan, such option may not be
re-priced by the Company.

    Generally, options may be exercised by the payment of the exercise price in
cash, certified check or wire transfer, or, subject to the approval of the
Executive Compensation and Option Committee, in cash equivalents, such as
through the tender of shares of the Company's Common Stock owned by the optionee
having a fair market value not less than the exercise price, by the assignment
of the proceeds of a sale of some or all of the shares of Common Stock being
acquired upon the exercise of the option, by way of a loan or in any combination
of these methods.

    Options granted under the 2000 Employee Stock Option Plan will become
exercisable at such times as may be specified by the Executive Compensation and
Option Committee, and generally become exercisable in five equal annual
installments subject to the optionee's continued employment or service with the
Company. The maximum term of options granted under the 2000 Employee Stock
Option Plan is ten years. Options are generally nontransferable by the optionee
other than by will or by the laws of descent and distribution and are
exercisable during the optionee's lifetime only by the optionee, or his guardian
or legal representative, except that, subject to certain restrictions, in
respect of incentive options, an optionee may, if permitted by the Executive
Compensation and Option Committee in its discretion, transfer an award or any
portion thereof, to one or more members of the optionee's immediate family.

    TERMS AND CONDITIONS OF OTHER AWARDS.  Each SAR or Restricted Stock award
made under the 2000 Employee Stock Option Plan is also evidenced by a written
agreement between the Company and the award holder specifying the number of
shares of Common Stock subject to the award and the other necessary terms and
conditions, consistent with the requirements of the 2000 Employee Stock Option
Plan. A SAR or Restricted Stock award may be granted separately or in
conjunction with the grant of an option. The terms included in the written
agreements evidencing these awards are summarized below.

    If a SAR is granted, the written agreement will specify if the SAR is being
granted separately or with respect to an outstanding option. In general, if a
SAR is granted with respect to an option, the exercise of the option will cancel
the SAR and the exercise of the SAR will cancel the option. An agreement
evidencing the SAR will also describe when the SAR will become vested and
exercisable, subject to the award holder's continued employment by the Company,
and the per share grant price. Upon settlement of the SAR award, occurring at
exercise, the award holder will receive a cash distribution of the difference
between the grant price of the Common Stock underlying the SAR and its fair
market value on the date of exercise.

    If shares of Restricted Stock are awarded, the agreement will specify the
per share grant price of the Common Stock subject to the restrictions, the
conditions that will result in the automatic and complete

                                       29
<PAGE>
forfeiture of the shares and the time and manner in which the restrictions will
lapse, subject to the award holder's continued employment by the Company. Upon
settlement of the Restricted Stock award, occurring upon the lapse of the
restrictions, the shares of Common Stock subject to the award will become
immediately distributable to the participant.

    CHANGE OF CONTROL PROVISIONS.  In general, a "Change of Control" will be
deemed to occur upon any of the following events in which the stockholders of
the Company do not retain, directly or indirectly, at least a majority of the
beneficial interest in the voting stock of the Company or its successor:
(i) the direct or indirect sale or exchange by the stockholders of the Company
of all or substantially all of the stock of the Company, (ii) a merger in which
the Company is a party, or (iii) the sale, exchange or transfer of all or
substantially all of the assets of the Company. If a participant terminates
employment within six months following a "Change of Control," all of the options
previously granted to him shall automatically become vested and immediately
exercisable; restrictions in Restricted Stock awards will also automatically
lapse upon a termination following a "Change of Control" and the Common Stock
subject to the award will become immediately distributable to the participant.

    TERMINATION OR AMENDMENT OF THE 2000 EMPLOYEE STOCK OPTION PLAN.  Unless
sooner terminated, no awards may be granted under the 2000 Employee Stock Option
Plan after September 11, 2010. The Board of Directors may terminate or amend the
2000 Employee Stock Option Plan at any time, but the Board of Directors may not
amend the 2000 Employee Stock Option Plan to increase the total number of shares
of Common Stock reserved for issuance of awards or adopt any amendment that
would materially increase the cost of the 2000 Employee Stock Option Plan to the
Company without stockholder approval. No amendment may be adopted that would
adversely affect an outstanding option or award without the participant's
consent.

SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES OF THE 2000 EMPLOYEE STOCK OPTION
  PLAN

    The following summary is intended only as a general guide as to the federal
income tax consequences under current law with respect to participation in the
2000 Employee Stock Option Plan and does not attempt to describe all possible
federal or other tax consequences of such participation. Furthermore, the tax
consequences of awards made under the 2000 Employee Stock Option Plan are
complex and subject to change, and a taxpayer's particular situation may be such
that some variation of the described rules is applicable.

    INCENTIVE STOCK OPTIONS.  Options designated as incentive stock options are
intended to fall within the provisions of Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"). An optionee recognizes no taxable income
for regular income tax purposes as the result of the grant or exercise of such
an option. If an optionee does not dispose of his shares for two years following
the date the option was granted or within one year following the transfer of the
shares upon exercise of the option, the gain on the sale of the shares (which is
the difference between the sale price and the purchase price of the shares) will
be taxed as long-term capital gain. If an optionee satisfies such holding
periods, upon a sale of the shares, the Company will not be entitled to any
deduction for federal income tax purposes. If an optionee disposes of the shares
within two years after the date of grant or within one year from the date of
exercise (a "disqualifying disposition"), the difference between the fair market
value of the shares on the date of exercise and the option exercise price (not
to exceed the gain realized on the sale if the disposition is a transaction with
respect to which a loss, if sustained, would be recognized) will be taxed as
ordinary income at the time of the disqualifying disposition. Any gain in excess
of that amount will be a capital gain. If a loss is recognized, there will be no
ordinary income, and such loss will be a capital loss. A capital gain or loss
will be long-term if the optionee's holding period is more than 12 months. Any
ordinary income recognized by the optionee upon the disqualifying disposition of
the shares should be deductible by the Company for federal income tax purposes,
except to the extent such deduction is limited by Section 162(m) of the Code.

                                       30

This Section of the Code disallows a public company's deductions for certain
employee remuneration exceeding $1,000,000 per year.

    NONSTATUTORY STOCK OPTIONS.  Options that do not qualify as incentive stock
options are nonstatutory stock options and have no special tax status. An
optionee generally recognizes no taxable income as the result of the grant of
such an option.

    Upon the exercise of a nonstatutory stock option, the optionee normally
recognizes ordinary income in the amount of the difference between the option
exercise price and the fair market value of the shares on the determination date
(which is generally the date of exercise). If the optionee is an employee, such
ordinary income generally is subject to withholding of income and employment
taxes. The "determination date" is the date on which the option is exercised
unless the sale of the shares at a profit would subject the optionee to suit
under Section 16(b) of the Exchange Act, in which case the determination date is
the date the sale of the shares at a profit would no longer subject the optionee
to suit under Section 16(b) of the Exchange Act. (Section 16(b) of the Exchange
Act generally is applicable only to officers, directors and beneficial owners of
more than 10% of the Common Stock of the Company.) Upon the sale of stock
acquired by the exercise of a nonstatutory stock option, any gain or loss, based
on the difference between the sale price and the fair market value on the date
of recognition of income, will be taxed as capital gain or loss. A capital gain
or loss will be long-term if the optionee's holding period is more than
12 months. No tax deduction is available to the Company with respect to the
grant of a nonstatutory option or the sale of the stock acquired pursuant to
such grant. The Company should be entitled to a deduction equal to the amount of
ordinary income recognized by the optionee as a result of the exercise of a
nonstatutory option, except to the extent such deduction is limited by
Section 162(m) of the Code.

    SARS AND RESTRICTED STOCK AWARDS. A participant will not be required to
recognize any income for federal income tax purposes upon the grant of a SAR or
shares of Restricted Stock. However, upon settlement of the SAR award (the date
of its exercise), the participant will be required to recognize as ordinary
income the difference between the strike price and the fair market value on the
date of its exercise of the shares of Common Stock on which the SAR award is
based. This amount will be taxed at ordinary federal income tax rates. Upon
settlement of the Restricted Stock award (the date the shares become
distributable), the participant will be required to recognize as ordinary income
the fair market value of the shares of Common Stock on such date. The Company
should be entitled to a deduction equal to the amount of the ordinary income
recognized by the participant upon the settlement of the SAR or Restricted Stock
award to the extent permitted by Section 162(m) of the Code.

                                 PROPOSAL NO. 4

        APPROVAL OF THE ADOPTION OF THE 2000 DIRECTOR STOCK OPTION PLAN.

    At its meeting on June 27, 2000, the Board of Directors of the Company
adopted the 2000 Director Stock Option Plan (the "2000 Director Stock Option
Plan") (a copy of which is attached hereto as Exhibit C) and directed that the
2000 Director Stock Option Plan be submitted to the stockholders for their
approval. The Board of Directors believes that the adoption of the 2000 Director
Stock Option Plan is in the best interests of the stockholders and the Company
because the ability to grant options thereunder is an important factor in
attracting, motivating and retaining distinguished personnel with proven ability
and vision to serve on the Board of Directors and the Advisory Board and to
chart the Company's course towards continued growth and financial success.

SUMMARY OF THE PROVISIONS OF THE 2000 DIRECTOR STOCK OPTION PLAN.

    The following summary of the 2000 Director Stock Option Plan is qualified in
its entirety by the specific language of the plan, a copy of which is attached
hereto as Exhibit C.

    GENERAL.  The 2000 Director Stock Option Plan is designed to enable the
Company to attract and retain persons of outstanding competence to serve as
members of the Board of Directors and the Advisory Board of the Company and to
provide a direct link between directors' or Advisory Board members' compensation
and stockholder value. Participation in the 2000 Director Stock Option Plan
initially will be restricted to non-employee directors and Advisory Board
members and only nonstatutory options to purchase shares of Common Stock will be
granted. The 2000 Director Stock Option Plan also provides that in the event of
any stock dividend, recapitalization, reorganization, merger, consolidation,
split-up, exchange of shares, combination, or like change in the capital
structure of the Company, appropriate adjustments will be made to the shares of
Common Stock subject to the 2000 Director Stock Option Plan and to any
outstanding awards. To the extent any outstanding option expires or terminates
prior to its exercise in full, the shares of Common Stock no longer subject to
the option will be returned to the 2000 Director Stock Option Plan and made
available for future grants.

    ADMINISTRATION.  The 2000 Director Stock Option Plan is administered by the
Executive Compensation and Option Committee of the Board of Directors of the
Company in compliance with the requirements of Rule 16b-3 of the Exchange Act.
Initial stock option grants, including all conditions of such grants, that are
made to eligible non-employee directors under the 2000 Director Stock Option
Plan are non-discretionary and are dictated by the written terms of the 2000
Director Stock Option Plan. Under the 2000 Director Stock Option Plan, upon an
eligible director's initial election or appointment to the Board of Directors of
the Company, the director is automatically granted a non-statutory stock option
to purchase 5,000 shares of Common Stock at its fair market value on the date of
grant. The Executive Compensation and Option Committee may make additional
discretionary options grants to eligible directors and Advisory Board members,
consistent with the terms of the 2000 Director Stock Option Plan. All options
granted under the 2000 Director Stock Option Plan are non-statutory stock
options. Subject to certain specific limitations and restrictions set forth in
the 2000 Director Stock Option Plan, the Executive Compensation and Option
Committee has the authority to interpret the 2000 Director Stock Option Plan, to
prescribe, amend and rescind rules and regulations, if any, relating to the 2000
Director Stock Option Plan and to make all determinations necessary or advisable
for the administration of the 2000 Director Stock Option Plan. The costs and
expenses of administering the 2000 Director Stock Option Plan are borne by the
Company.

    ELIGIBILITY.  Participation in the 2000 Director Stock Option Plan is
limited to persons who serve as members of the Board of Directors and the
Advisory Board of the Company and who, at the time of the option grant, are not
employees of the Company. For purposes of determining the exercise period of
prior grants under the 2000 Director Stock Option Plan, any member of the Board
of Directors who resigns as a

                                       32
<PAGE>
director in order to become a member of the Advisory Board shall be deemed
during his period of service as a member of the Advisory Board to be a
continuing member of the Board of Directors and any member of the Advisory Board
who resigns as a member of the Advisory Board to become a member of the Board of
Directors shall be deemed during his period of service as a member of the Board
of Directors to be a continuing member of the Board of Directors.

    TERMS AND CONDITIONS OF OPTION GRANTS.  The 2000 Director Stock Option Plan
provides for each non-employee director automatically to receive, upon election
to office or appointment to the Board of Directors, an option to acquire 5,000
shares of Common Stock at a price equal to the fair market value at the date of
the grant of the shares of Common Stock subject to such option. Pursuant to the
terms of the 2000 Director Stock Option Plan, each automatic option shall become
vested and exercisable on the earlier of (i) the first anniversary of the grant
date, provided the director remains in the continuous service of the Board of
Directors, during such period, (ii) upon the director's termination of Board of
Directors service due to retirement, death or disability, or (iii) the period,
if any, determined by the Executive Compensation and Option Committee in its
sole discretion. If a director's service is terminated for "cause" all awards
granted to the director under the 2000 Director Stock Option Plan will
automatically be forfeited. In the event a director's service on the Board of
Directors terminates before the options have vested, any unvested option shall
be canceled and the director shall have no further right or interest in the
forfeited option. The 2000 Director Stock Option Plan does not provide for the
vesting of outstanding options to be accelerated upon a "Change of Control" of
the Company. Each option shall remain outstanding until the tenth anniversary of
the grant date.

    All of the terms and conditions of option grants are specified in a written
agreement between the Company and the optionee. In addition, the Executive
Compensation and Option Committee may make additional discretionary option
grants to eligible directors and members of the Advisory Board the terms of
which shall be determined by the Executive Compensation and Option Committee,
consistent with the provisions of the 2000 Director Stock Option Plan and
specified in a written agreement. Neither the existence of the 2000 Director
Stock Option Plan, nor the granting of an option thereunder, will be construed
to limit, in any way, the right of the Company or its stockholders to elect a
person to serve as a director or the right of the Board of Directors to appoint
a person to serve as a member of the Advisory Board. In addition, nothing in the
2000 Director Stock Option Plan shall be construed to give any director or
Advisory Board member the right to a grant of an option under the 2000 Director
Stock Option Plan unless the express terms and conditions of the 2000 Director
Stock Option Plan are satisfied.

    Options may be exercised by the payment of the exercise price in cash,
certified check or wire transfer or, subject to the approval of the Executive
Compensation and Option Committee, in cash equivalents, such as through the
tender of shares of the Company's Common Stock owned by the optionee having a
fair market value not less than the exercise price, by the assignment of the
proceeds of a sale of some or all of the shares of Common Stock being acquired
upon the exercise of the option, by way of a loan or in any combination of these
methods. Options are generally nontransferable by the optionee other than by
will or by the laws of descent and distribution and are exercisable during the
optionee's lifetime only by the optionee.

    TERMINATION OR AMENDMENT OF THE 2000 DIRECTOR STOCK OPTION PLAN.  Unless
sooner terminated, no awards may be granted under the 2000 Director Stock Option
Plan after September 11, 2010. The Board of Directors may terminate or amend the
2000 Director Stock Option Plan at any time, but the Board of Directors may not
amend the 2000 Director Stock Option Plan to increase the total number of shares
of Common Stock reserved for issuance of awards or adopt any amendment that
would materially increase the cost of the 2000 Director Stock Option Plan to the
Company without stockholder approval. No amendment may be adopted that would
adversely affect an outstanding option or award without the participant's
consent.

                                       33
<PAGE>
    SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES OF THE 2000 DIRECTOR STOCK OPTION
PLAN.  In general, no gain or loss is recognized by the option holder at the
time an option is granted under the 2000 Director Stock Option Plan. Upon the
exercise of an option, the difference between the fair market value of the
Common Stock on the date of exercise and the option price will be taxable as
compensation income to the option holder and the Company would be entitled to a
deduction for federal income tax purposes for the same amount. Upon a subsequent
sale or exchange of stock acquired pursuant to the exercise of an option, the
option holder would have taxable gain or loss, measured by the difference
between the amount realized on the disposition and the tax basis of such shares.
The foregoing statements are intended to summarize the general principles of
current federal income tax law applicable to options that may be granted under
the 2000 Director Stock Option Plan. The tax consequences of awards made under
the 2000 Director Stock Option Plan are complex, subject to change and may vary
depending on the taxpayer's particular circumstances.

VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION.

    Assuming a quorum is present, the affirmative vote of a majority of the
votes cast on this proposal at the Annual Meeting is required for approval of
this Proposal No. 4, provided that the total votes cast on this proposal
represent over 50% in interest of all securities entitled to vote on this
proposal. For purposes of the vote on this Proposal No. 4, an abstention or a
broker non-vote will have the effect of a vote against this proposal unless the
total votes cast on this proposal represent more than 50% in interest of all
securities entitled to vote on this proposal, in which event neither an
abstention nor a broker non-vote will have any effect on the result of the vote.

    THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE ADOPTION OF THE
2000 DIRECTOR STOCK OPTION PLAN.

    The Committee shall have at least three (3) members at all times, each of

                        2000 EMPLOYEE STOCK OPTION PLAN

SECTION 1.  INTRODUCTION.

    1.1  PURPOSE.  The purpose of the 2000 Employee Stock Option Plan (the
"Plan") is to advance and promote the interests of Mack-Cali Realty Corporation
(the "Corporation") and its Subsidiaries by providing employees, consultants and
advisors of the Corporation or its Subsidiaries with an incentive to achieve
corporate objectives, to attract and retain employees, consultants and advisors
of outstanding competence and to provide such individuals with an equity
interest in the Corporation through the acquisition of Common Stock and by
providing for payments to such individuals based on the appreciation in value or
value of such Common Stock. The Plan is intended to be construed as an employee
benefit plan that satisfies the requirements for exemption from the restrictions
of Section 16(b) of the Securities Exchange Act of 1934, as amended, pursuant to
the applicable rules promulgated thereunder.

    1.2  DEFINITIONS.  The following definitions are applicable to the Plan:

    (a) Award.

    "Award" means Options, Restricted Stock, Stock Appreciation Rights (SARs) or
any combination thereof, granted under the Plan.

    (b) Award Agreement.

    "Award Agreement" means the written agreement by which an Award shall be
evidenced.

    (c) Beneficiary.

    "Beneficiary" means the beneficiary or beneficiaries designated in
accordance with Section 5.8 hereof to receive the amount, if any, payable under
the Plan upon the death of a Participant.

    (d) Board.

    "Board" means the Board of Directors of the Corporation.

    (e) Change in Control.

    "Change in Control" means that any of the following events has occurred:

        (i) any "person" or "group" of persons, as such terms are used in
            Sections 13 and 14 of the Exchange Act, other than the Corporation,
            any of its Subsidiaries, or any employee benefit plan sponsored by

SECTION 2.  OPTIONS.

    2.1  AWARDS OF OPTIONS.  Subject to the provisions of the Plan, the
Committee shall determine and designate from time to time those Eligible
Individuals to whom Incentive Stock Options, or Non-qualified Stock Options, or
both, shall be granted and the number of Shares to be granted to each such
Eligible Individual; PROVIDED, HOWEVER, that only Key Employees may receive
Incentive Stock Options and the aggregate fair market value (determined at the
time the Option is granted) of the shares with respect to which any incentive
stock options are exercisable for the first time by any Key Employee during any
calendar year under all incentive stock option plans of the Corporation and any
Subsidiary shall not exceed one hundred thousand dollars ($100,000) or such
other limit set forth in Section 422 of the Code (the "Limitations of the
Code"). If the aggregate fair market value of such shares exceeds the
Limitations of the Code, the excess Shares will be treated as Non-qualified
Options under this Plan. In reducing the number of Incentive Stock Options to
meet the Limitations of the Code, the most recently granted Incentive Stock
Options shall be reduced first. If a reduction of simultaneously granted Options
is necessary to meet the Limitations of the Code, the Committee may designate
which Shares are to be treated as Shares acquired pursuant to an Incentive Stock
Option. In the event that any Incentive Stock Options granted under the Plan
fail to meet the requirements for Incentive Stock Options as set forth in the
Code, such Incentive Stock Options will be treated as Non-qualified Stock
Options under the Plan. In determining the Eligible Individuals who will be
granted Options under the Plan, the Committee may consider such individuals'
responsibilities, service, present and future value to the Corporation or any
Subsidiary and other factors it considers relevant.

    2.2  TERMS AND CONDITIONS OF OPTIONS.  Except as otherwise provided in a
Participant's employment or other agreement with the Corporation or any

Subsidiary:

    Agreement or employment or other agreement with the Corporation or any
    Subsidiary. The Committee may extend such Option Term; PROVIDED, HOWEVER,
    that (i) such extension shall not in any way disqualify the Option as an
    Incentive Stock Option and (ii) the Option Term, including any such
    extensions, shall not exceed ten (10) years.

        (b)  OPTION PRICE. The Option Price per Share shall be determined by the

    the case of an Incentive Stock Option granted to a 10% Owner, the Option
    Price shall not be less than one hundred ten percent (110%) of the Fair
    Market Value of a Share on the Grant Date, (but in no event less than the
    par value of a Share).

        (c)  EXERCISE OF OPTION. The exercisability of an Option shall be
    determined by the Committee. Subject to acceleration or early expiration as

    granted under the Plan shall be subject to the Participant remaining in the
    employ of or maintaining a consultancy with the Corporation or any of its
    Subsidiaries and shall vest (i) in five (5) equal installments of twenty
    percent (20%) of the amount granted, with the first installment vesting on
    the December 31st next following the Grant Date and each other installment

    Participant who is granted an Incentive Stock Option to notify the
    Corporation of any disposition of such Shares issued upon the exercise of
    such Incentive Stock Option under the circumstances described in

            so on the date of such termination, at any time, or from time to
            time, but not later than (x) the expiration date specified in

            vested and exercisable as of the date of the Participant's
            termination of employment shall automatically expire and be
            forfeited as of such date of termination.

        (ii) UPON TERMINATION DUE TO DEATH. In the event a Participant's
             employment or consultancy shall terminate by reason of his or her
             death, such Participant's Beneficiary, heirs or estate may exercise
             his or her Options, to the extent that such Participant, if such
             Participant had not died, would have been entitled to do so within
             the calendar year following such Participant's death, at any time,
             or from time to time, but not later than (x) the expiration date
             specified in Subsection 2.2(a) hereof or (y) one year after the
             date of death, whichever is earlier and any portion of any Option
             granted hereunder that would not have vested and been exercisable
             within the calendar year following such Participant's death if such
             Participant had not died shall automatically expire and be
             forfeited as of the date of such Participant's death.

       (iii) UPON A CHANGE IN CONTROL. In the event a Participant's employment
             or consultancy shall terminate within six (6) months following a
             Change in Control, all Options granted under the Plan which the
             Participant shall not then have been entitled to exercise shall be
             accelerated as of the date of such termination and the Participant
             may exercise all such Options at any time, or from time to time,
             but not later than (x) the expiration date specified in Subsection
             2.2(a) hereof or (y) three (3) months after such termination,

    Option granted under the Plan shall be transferable other than by will or by
    the laws of descent and distribution and during the lifetime of the
    Participant, shall be exercisable only by the Participant or his or her
    guardian or legal representative.

        (h)  INVESTMENT REPRESENTATION. Each Award Agreement for an Option shall
    provide that, upon demand by the Committee for such a representation, the

    deliver to the Committee, at the time of any exercise of an Option or
    portion thereof, a written representation that the Shares to be acquired
    upon such exercise are to be acquired for investment and not for resale or
    with a view to the distribution thereof. Upon such demand, delivery of such
    representation prior to the delivery of any Common Stock issued upon
    exercise of an Option and prior to the expiration of the Option Term shall
    be a condition precedent to the right of the Participant or such other
    person to purchase any Common Stock. In the event certificates for Common
    Stock are delivered under the Plan with respect to which such an investment
    representation has been obtained, the Committee may cause a legend or
    legends to be placed on such certificates to make appropriate reference to
    such representations and to restrict transfer in the absence of compliance
    with applicable federal or state securities laws.

        (i)  PARTICIPANTS TO HAVE NO RIGHTS AS SHAREHOLDERS. No Participant
    shall have any rights as a shareholder with respect to any Common Stock
    subject to his or her Option prior to the date of issuance to him or her of
    such Common Stock.

        (j)  OTHER OPTION PROVISIONS. The Committee may require a Participant to

exercise of such Option.

    3.2  STRIKE PRICE.  The strike price ("Strike Price") of any SAR shall
equal, for any SAR that is identified with an Option, the Option Price of such
Option, or for any other SAR, 100% of the Fair Market Value of a Share on the

Strike Price in the Award Agreement or (y) provide that the benefit payable upon
exercise of any SAR shall not exceed a percentage of Fair Market Value of a
Share on such Grant Date as the Committee shall specify.

Agreement or in the Participant's employment or other agreement with the
Corporation or any Subsidiary, (x) each SAR not identified with any other Award

each of the first five December 31st following the Grant Date of such SAR or in
such other amounts and over such other time period as may be determined by the

result in the cancellation or forfeiture of such Option, to the extent of such
exercise and any such Shares so canceled or forfeited shall not thereafter again

Corporation or any Subsidiary or Award Agreement, the following provisions shall
apply upon termination of a Participant's employment or consultancy with the

            Subsidiary shall terminate for any reason other than by reason of
            his or her death, such Participant may exercise his or her SARs, to
            the extent that such Participant shall have been entitled to do so
            on the date of such termination, at any time, or from time to time,
            but not later than (x) the expiration date specified in Subsection
            2.2(a) hereof or (y) three (3) months after the date of such

            hereunder that are not vested and exercisable as of the date of the
            Participant's termination of employment shall automatically expire
            and be forfeited as of such date of termination.

        (ii) UPON TERMINATION DUE TO DEATH. In the event a Participant's
             employment or consultancy shall terminate by reason of his or her
             death, such Participant's Beneficiary, heirs or estate may exercise
             his or her SARs, to the extent that such Participant, if such
             Participant had not died, would have been entitled to do so within
             the calendar year following such Participant's

                                      B-9
<PAGE>
             death, at any time, or from time to time, but not later than
             (x) the expiration date specified in Subsection 2.2(a) hereof or
             (y) one year after the date of death, whichever is earlier and any
             SARs granted hereunder that would not have vested and been
             exercisable within the calendar year following such Participant's
             death if such Participant had not died shall automatically expire
             and be forfeited as of the date of such Participant's death.

       (iii) UPON A CHANGE IN CONTROL. In the event a Participant's employment
             or consultancy shall terminate within six (6) months following a
             Change in Control, all SARs granted under the Plan which the
             Participant shall not then have been entitled to exercise shall be
             accelerated as of the date of such termination and the Participant
             may exercise all such SARs at any time, or from time to time, but
             not later than (x) the expiration date specified in Subsection
             2.2(a) hereof or (y) three (3) months after such termination,
             whichever is earlier.

SECTION 4.  RESTRICTED STOCK.

    4.1  AWARDS OF RESTRICTED STOCK.  Restricted Stock awarded under this Plan
shall be subject to certain Restrictions as provided below. All Restrictions
imposed on any such Award of Restricted Stock shall be made by and at the
discretion of the Committee, subject to the provisions of the Plan, and are
binding on the Corporation and the Participants, their Beneficiaries and legal
representatives.

    4.2  RESTRICTED PERIOD/RESTRICTIONS.  At the time each Award of Restricted
Stock is granted, the Committee (i) shall establish a Restricted Period within
which Restricted Stock awarded to the Participants may not be sold, assigned,
transferred, made subject to gift, or otherwise disposed of, mortgaged, pledged
or otherwise encumbered, if any and (ii) may impose such other Restrictions on
any Restricted Stock as it may deem advisable.

    4.3  RIGHTS AS STOCKHOLDERS.  Except for the conditions outlined in
Section 4.2 hereof, and the forfeiture conditions described in Section 4.5
hereof, each Participant shall have all rights of a holder of Common Stock,
including the right to receive all dividends or other distributions made or paid
in respect of such Shares and the right to vote such Shares at regular or
special meetings of the shareholders of the Corporation.

    4.4  DELIVERY OF SHARES.  The certificates for any Restricted Stock awarded
to an Eligible Individual under the Plan shall be held (together with a stock
power executed in blank by the Eligible Individual) in escrow by the Secretary
of the Corporation under the Participant's name in an account maintained by the
Corporation until such Shares of Restricted Stock become nonforfeitable or are
forfeited. At the conclusion of the Restricted Period or the expiration or
attainment of such other Restrictions imposed on any Restricted Stock granted to
a Participant, or upon the prior approval of the Committee as described in
Section 4.5 hereof, and subject to the satisfaction of the Corporation's
withholding obligations described in Section 5.8 hereof, certificates
representing such Shares of Restricted Stock shall be delivered to the
Participant, or the Beneficiary or legal representative of the Participant, free
of the Restrictions set forth in the Award Agreement pursuant to Section 4.2
hereof.

other agreement with the Corporation or any Subsidiary, the following provisions
shall apply upon termination of a Participant's employment or consultancy with

        (i) UPON TERMINATION FOR ANY REASON OTHER THAN DUE TO DEATH. If a
            Participant's employment or consultancy with the Corporation or any
            Subsidiary is terminated, except termination due to death, all
            Restricted Stock awarded under the Plan which are then subject to a
            Restricted Period or other Restrictions will be forfeited and become
            the property of the Corporation on the date of such termination.
            However, the Committee may, if it, in its sole discretion,
            determines that the circumstances warrant such action, approve the
            release of all or any part

                                      B-10
<PAGE>
            of the Restricted Stock which would otherwise be forfeited pursuant
            to this Section, upon such conditions as it shall determine.

        (ii) UPON DUE TO DEATH. If a Participant's employment or consultancy
             with the Corporation or a Subsidiary is terminated due to death,
             all Shares of Restricted Stock awarded under the Plan which are
             then subject to a Restricted Period or other Restrictions and which
             would have been released, if the Participant had not died, within
             the calendar year following the Participant's death shall be
             released on the date of such termination as if with respect to such
             Shares the Restricted Period had ended and the other Restrictions
             had lapsed and certificates representing such Shares of Restricted
             Stock shall be delivered to the Participant's Beneficiary or legal
             representative free from such Restrictions as soon as practicable
             following such termination and all other Shares of Restricted Stock
             which would not have been released, if the Participant had not
             died, within the calendar year following the Participant's death
             will be forfeited and become the property of the Corporation on the
             date of such termination.

    4.6  SECTION 83(B) ELECTIONS.  A Participant who files an election permitted
under Section 83(b) of the Code with the Internal Revenue Service to include the
fair market value of any Restricted Stock in gross income while they are still
subject to a Restricted Period or other Restrictions shall notify the
Corporation of such election within ten (10) days of making such election and
promptly furnish the Corporation with a copy of such election together with the
amount of any federal, state, local or other taxes required to be withheld to
enable the Corporation to claim an income tax deduction with respect to such
election.

    4.7  CHANGE IN CONTROL.  In the event of a Change in Control, all Restricted
Periods shall end, the Restricted Period or other Restrictions applicable to all
previously granted Awards of Restricted Stock shall end or lapse, as the case
may be, and such Shares shall be released and certificates representing such
Shares of Restricted Stock shall be delivered to the Participants free from such
Restrictions as soon as practicable following such Change in Control.

SECTION 5.  GENERAL PROVISIONS.

    5.1  GENERAL CREDITOR STATUS.  Participants shall have no right, title, or
interest whatsoever in or to any investments which the Corporation may make to
aid it in meeting its obligations under the Plan. Nothing contained in the Plan,
and no action taken pursuant to its provisions, shall create or be construed to
create a trust of any kind, or a fiduciary relationship between the Corporation
and any Participant, Beneficiary, legal representative or any other person. To
the extent that any person acquires a right to receive payments from the
Corporation under the Plan, such right shall be no greater than the right of an
unsecured general creditor of the Corporation. All payments to be made hereunder
shall be paid from the general funds of the Corporation and no special or
separate fund shall be established and no segregation of assets shall be made to
assure payment of such amounts except as expressly set forth in the Plan;
PROVIDED, HOWEVER, that in its sole discretion, the Committee may authorize the
creation of trusts or other arrangements to meet the obligations created under
the Plan to deliver Common Stock or pay cash; PROVIDED, FURTHER, HOWEVER, that,
unless the Committee otherwise determines with the consent of the affected
Participant, the existence of such trusts or other arrangements shall be
consistent with the "unfunded" status of the Plan.

    5.2  CERTAIN ADJUSTMENTS TO SHARES.  In the event of any change in the
Common Stock by reason of any stock dividend, recapitalization, reorganization,
spin-off, split-off, merger, consolidation, stock split, reverse stock split,
combination or exchange of shares, or any rights offering to purchase Common
Stock at a price substantially below fair market value, or of any similar change
affecting the Common Stock of or by the Corporation, the number and kind of
Shares available for Awards under the Plan and the number and kind of Shares
subject to a Restricted Period or other Restrictions or subject to Options in
outstanding Awards and the Option Price or purchase price per Share thereof
shall be appropriately adjusted consistent with such change in such manner as
the Committee may deem equitable to prevent substantial

                                      B-11
<PAGE>
dilution or enlargement of the rights granted to, or available for, the
Participants hereunder. Any adjustment of an Incentive Stock Option pursuant to
this Section shall be made only to the extent not constituting a "modification"
within the meaning of Section 424(h)(3) of the Code, unless the holder of such
Option shall agree otherwise. The Committee shall give notice to each
Participant of any adjustment made pursuant to this Section and, upon notice,
such adjustment shall be effective and binding for all purposes of the Plan.

    5.3  SUCCESSOR CORPORATION.  The obligations of the Corporation under the
Plan shall be binding upon any successor corporation or organization resulting
from the merger, consolidation or other reorganization of the Corporation, or
upon any successor corporation or organization succeeding to substantially all
of the assets and business of the Corporation. The Corporation agrees that it
will make appropriate provision for the preservation of Participants' rights
under the Plan in any agreement or plan which it may enter into or adopt to
effect any such merger, consolidation, reorganization or transfer of assets.

    5.4  NO CLAIM OR RIGHT UNDER THE PLAN.  Neither the Plan nor any action
taken thereunder shall be construed as giving any employee, consultant or
advisor any right to be retained in the employ of or by the Corporation.

    5.5  AWARDS NOT TREATED AS COMPENSATION UNDER BENEFIT PLANS.  No Award shall
be considered as compensation under any employee benefit plan of the
Corporation, except as specifically provided in any such plan or as otherwise
determined by the Board.

    5.6  LISTING AND QUALIFICATION OF COMMON STOCK.  The Corporation, in its
discretion, may postpone the issuance or delivery of Common Stock upon any
exercise of an Option or pursuant to an Award of Restricted Stock until
completion of such stock exchange listing or other qualification of such shares
under any state or federal law, rule or regulation as the Corporation may
consider appropriate, and may require any Participant, Beneficiary or legal
representative to make such representations and furnish such information as it
may consider appropriate in connection with the issuance or delivery of the
shares in compliance with applicable laws, rules and regulations.

    5.7  WITHHOLDING TAXES.  The Corporation may make such provisions and take
such steps as it may deem necessary or appropriate for the withholding of all
federal, state and local taxes required by law to be withheld with respect to
Awards granted pursuant to the Plan including, but not limited to (i) accepting
a remittance from the Participant in cash, or in the Committee's discretion in
Mature Shares (ii) deducting the amount required to be withheld from any other
amount then or thereafter payable by the Corporation or Subsidiary to a
Participant, Beneficiary or legal representative or from any Shares due to the
Participant under the Plan, (iii) requiring a Participant, Beneficiary or legal
representative to pay to the Corporation the amount required to be withheld as a
condition of releasing Common Stock or (iv) any combination of the foregoing. In
addition, subject to such rules and regulations as the Committee shall from time
to time establish, Participants shall be permitted to satisfy federal, state and
local taxes, if any, imposed upon the payment of Awards in Common Stock at a
rate up to such Participant's maximum marginal tax rate with respect to each
such tax by (i) irrevocably electing to have the Corporation deduct from the
number of Shares otherwise deliverable in payment of an Award such number of
Shares as shall have a value equal to the amount of tax to be withheld,
(ii) delivering to the Corporation such portion of the Common Stock delivered in
payment of the Award as shall have a value equal to the amount of tax to be
withheld, or (iii) delivering to the Corporation such number of Mature Shares or
combination of Mature Shares and cash as shall have a value equal to the amount
of tax to be withheld.

    5.8  NON-TRANSFERABILITY/DESIGNATION AND CHANGE OF BENEFICIARY.

        (a)  An Award granted hereunder shall not be assignable or transferable
    other than by will or by the laws of descent and distribution and may be
    exercised during the Participant's lifetime only by the Participant or his
    or her guardian or legal representative, except that, subject to
    Section 2.2(f) hereof, in respect of Incentive Stock Options, a Participant
    may, if permitted by the Committee, in its

                                      B-12
<PAGE>
    discretion, transfer an Award, or any portion thereof, to one or more
    members of the Participant's Immediate Family.

        (b)  Each Participant shall file with the Committee a written
    designation of one or more persons as the Beneficiary who shall be entitled
    to receive the amount, if any, payable under the Plan upon his or her death.
    A Participant may, from time to time, revoke or change his or her
    Beneficiary designation without the consent of any prior Beneficiary by
    filing a new designation with the Committee. The last such designation
    received by the Committee shall be controlling; PROVIDED, HOWEVER, that no
    designation, or change or revocation thereof, shall be effective unless
    received by the Committee prior to the Participant's death, and in no event
    shall it be effective as of a date prior to such receipt.

    5.9  PAYMENTS TO PERSONS OTHER THAN A PARTICIPANT.  If the Committee shall
find that any person to whom any amount is payable under the Plan is unable to
care for his or her affairs because of illness or accident, or is a minor, or
has died, then any payment due to such person or his or her estate (unless a
prior claim therefor has been made by a duly appointed legal representative),
may, if the Committee so directs the Corporation, be paid to his or her spouse,
a child, a relative, an institution maintaining or having custody of such
person, or any other person deemed by the Committee to be a proper recipient on
behalf of such person otherwise entitled to payment. Any such payment shall be a
complete discharge of the liability of the Committee and the Corporation
therefor.

    5.10  NO LIABILITY OF COMMITTEE MEMBERS.  No member of the Committee shall
be personally liable by reason of any contract or other instrument executed by
such member or on his or her behalf in his or her capacity as a member of the
Committee nor for any mistake of judgment made in good faith, and the
Corporation shall indemnify and hold harmless each employee, officer or director
of the Corporation to whom any duty or power relating to the administration or
interpretation of the Plan may be allocated or delegated, against any cost or
expense (including counsel fees) or liability (including any sum paid in
settlement of a claim with the approval of the Board) arising out of any act or
omission to act in connection with the Plan unless arising out of such person's
own fraud or bad faith. The indemnification provided for in this Section 5.10
shall be in addition to any rights of indemnification such Committee member has
as a director or officer pursuant to law, under the Certificate of Incorporation
or By-Laws of the Corporation.

    5.11  AMENDMENT OR TERMINATION.  Except as to matters that in the opinion of
the Corporation's legal counsel require stockholder approval, any provision of
the Plan may be modified as to a Participant by an individual agreement approved
by the Committee. The Board may, with prospective or retroactive effect, amend,
suspend or terminate the Plan or any portion thereof at any time; PROVIDED,
HOWEVER, that (i) no amendment that would materially increase the cost of the
Plan to the Corporation may be made by the Board without the approval of the
stockholders of the Corporation and (ii) no amendment, suspension or termination
of the Plan shall deprive any Participant of any rights to Awards previously
made under the Plan without his or her written consent. Subject to earlier
termination pursuant to the provisions of this Section, and unless the
stockholders of the Corporation shall have approved an extension of the Plan
beyond such date, the Plan shall terminate and no further Awards shall be made
under the Plan after the tenth (10th) anniversary of the Effective Date of the
Plan specified in Section 5.15 hereof.

    5.12  UNFUNDED PLAN.  The Plan is intended to constitute an unfunded
deferred compensation arrangement.

    5.13  GOVERNING LAW.  The Plan shall be governed by and construed in
accordance with the laws of the State of Maryland, without reference to the
principles of conflicts of law thereof.

    5.14  NON-UNIFORM DETERMINATIONS.  The Committee's determinations under the
Plan need not be uniform and may be made by the Committee selectively among
persons who receive, or are eligible to receive, Awards whether or not such
persons are similarly situated. Without limiting the generality of the
foregoing, the Committee shall be entitled, to enter into non-uniform and
selective Award Agreements as

                                      B-13
<PAGE>
to (a) the identity of the Participant, (b) the terms and provisions of Awards,
and (c) the treatment of termination of employment or consultancies.

    5.15  EFFECTIVE DATE.  The Plan is effective September 11, 2000.

    5.16  NO ILLEGAL TRANSACTIONS.  The Plan and all Awards granted pursuant to
it are subject to all applicable laws and regulations. Notwithstanding any
provision of the Plan or any Award, Participants shall not be entitled to
exercise or receive benefits under, any Award, and the Corporation shall not be
obligated to deliver any Shares or deliver any benefits to a Participant, if
such exercise or delivery would constitute a violation by the Participant or the
Corporation of any applicable law or regulation.

    5.17  SEVERABILITY.  If any part of the Plan is declared by any court of
governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not invalidate any other part of the Plan. Any Section or part
of a Section so declared to be unlawful or invalid shall, if possible, be
construed in manner which will give effect to the terms of such Section to the
fullest extent possible while remaining lawful and valid.

SECTION 3.  ADMINISTRATION.

    The Plan shall be administered by a committee (the "Administrative
Committee), which shall consist of two or more directors of the Corporation, all
of whom qualify as "Non-Employee Directors" as defined in Rule 16b-3 of the
Exchange Act. The number of members of the Administrative Committee shall from
time to time be increased or decreased, and shall be subject to such conditions,
in each case as the Board deems appropriate to permit transactions in Shares
pursuant to the Plan to satisfy such conditions of Rule 16b-3 as then in effect.
In the event that the Compensation Committee of the Board (the "Compensation
Committee) meets the requirements set forth in this Section 3 hereof, such
Compensation Committee shall be the Administrative Committee hereunder unless
otherwise determined by the Board.

    A majority of the members of the Administrative Committee shall constitute a
quorum. The Administrative Committee may act at a meeting, including a
telephonic meeting, by action of a majority of the members present, or without a
meeting by unanimous written consent.

    Subject to the express provisions of the Plan, the Committee shall have full
and final authority and discretion as follows:

    (i) select the Eligible Directors and Eligible Advisory Board Members
        entitled to receive Discretionary Options pursuant to Section 6.3
        hereof;

    (ii) grant Discretionary Options to those Participants it selects in such
         amounts as it shall determine, subject to the terms and conditions of
         the Plan;

   (iii) determine the number of Shares to be covered by each Discretionary
         Option granted under the Plan and the time or times when and the manner
         in which such Discretionary Option shall be exercisable;

    (iv) to accelerate the exercisability (including exercisability within a
         period of less than one year after the Grant Date) of, and to
         accelerate or waive any or all of the terms and conditions applicable
         to, any Option or any group of Options for any reason and at any time,
         including in connection with a termination of service (other than for
         Cause);

    (v) subject to the provisions of the Plan, to extend the time during which
        any Option or group of Options may be exercised;

    (vi) to interpret the Plan and make all determinations necessary or
         advisable for the administration of the Plan including the
         establishment, amendment or revocation from time to time of guidelines
         or regulations for the administration of the Plan, to cause appropriate
         records to be established, and to make all determinations and take all
         other actions considered necessary or advisable for the administration
         of the Plan; and

   (vii) to take any other action with respect to any matters relating to the
         Plan for which it is responsible.

    All decisions, actions or interpretations of the Administrative Committee on
all matters relating to the Plan or any Option Agreement shall be final, binding
and conclusive upon all parties. No member of the Administrative Committee shall
be liable for any action or determination made in good faith with respect to the

    4.2  DISCRETIONARY OPTIONS.

    The Administrative Committee, may, in its discretion grant Discretionary
Options to any Eligible Director or Eligible Advisory Board Member, whether or
not he or she has previously received an Option. No such Eligible Directors or
Eligible Advisory Board Members shall at any time have the right to receive a

Administrative Committee.

SECTION 5.  MAXIMUM NUMBER OF SHARES AVAILABLE FOR OPTIONS.

    Subject to adjustment in accordance with Section 7.2 hereof, the maximum

In the event any Options granted under the Plan shall be forfeited, terminate or
expire, the number of Shares no longer subject to such Option, to the extent of
such forfeiture, termination or expiration, shall thereafter again be available
for grant under the Plan. The Common Stock distributed under the Plan may be
authorized and unissued shares, shares held in the treasury of the Corporation,
or shares purchased on the open market by the Corporation (at such time or times
and in such manner as it may determine). The Corporation shall be under no
obligation to acquire Common Stock for distribution to Participants before

Committee grants the Option or such later date as specified in advance by the
Administrative Committee. All Options shall be evidenced by an Option Agreement

       of any Option may be exercised until the Participant shall have remained
       a member of the Board or Advisory Board, as the case may be, for the

       combination of cash and Mature Shares having a total fair market value,
       as so determined, equal to the Option Price for such Shares,

       following provisions shall apply upon termination of a Participant's
       status as a member of the Board or Advisory Board:

            Participant's status as a member of the Board or the Advisory Board
            shall terminate because of his or her death, Disability or
            Retirement, the Participant, Beneficiary or legal representative
            shall have the right to exercise all Options regardless of whether
            such Options are vested, at any time and from time to time, but not
            later than (x) one year following the date of death or Disability,
            (ii) one year following the date of Retirement, or (iii) the
            expiration date specified in Section 6.4(a) hereof, whichever is
            earlier.

        (ii) UPON TERMINATION FOR ANY REASON OTHER THAN DUE TO DEATH,
             DISABILITY, RETIREMENT OR FOR CAUSE. If a Participant' s status as
             a member of the Board or Advisory Board shall terminate for any
             reason other than due to the Participant's death, Disability,
             Retirement or termination for Cause, such Participant shall have
             the right to exercise his or her Options, to the extent that such
             Participant shall have been entitled to do so on the date of such
             termination, at any time and from time to time, but not later than
             (i) on the expiration date specified in Section 6.4(a) hereof or
             (ii) three (3) months after the date of such termination of
             service, whichever date is earlier and the portion of any Option
             granted hereunder that is not vested and exercisable as of the date
             of such termination of service shall automatically expire and be
             forfeited as of the date of such termination of service.

       (iii) UPON TERMINATION FOR CAUSE. If a Participant's status as a member
             of the Board or Advisory Board shall terminate for Cause, all
             Options regardless of whether such Options are vested or not shall
             be forfeited and canceled on the date of such termination.

                                      C-6
<PAGE>
    (f) TRANSFER OF SERVICE FROM BOARD TO ADVISORY BOARD OR VICE VERSA. For
       purposes of determining the exercise period and vesting of Options
       granted hereunder, (i) a Participant who resigns as a member of the Board
       in order to become a member of the Advisory Board shall be deemed during
       his or her period of service as a member of the Advisory Board to be a
       continuing member of the Board and (ii) a Participant who resigns as a
       member of the Advisory Board in order to become a member of the Board
       shall be deemed during his or her period of service as a member of the
       Board to be a continuing member of the Advisory Board.

    (g) TRANSFERABILITY OF OPTIONS. Subject to Section 7.8 hereof, no Options
       granted under the Plan shall be transferable other than by will or by the
       laws of descent and distribution. During the lifetime of the Participant,
       an Option shall be exercisable only by such Participant.

    (h) PARTICIPANTS TO HAVE NO RIGHTS AS STOCKHOLDERS. No Participant shall
       have any rights as a stockholder with respect to any Common Stock subject
       to his or her Option prior to the date of issuance to him or her of such
       Common Stock.

    (i) INVESTMENT REPRESENTATION. Each Option Agreement for an Option shall
       provide that, upon demand by the Administrative Committee for such a
       representation, the Participant (or any person acting under Subsection
       6.4(e) hereof) shall deliver to the Administrative Committee, at the time
       of any exercise of an Option or portion thereof, a written representation
       that the Shares to be acquired upon such exercise are to be acquired for
       investment and not for resale or with a view to the distribution thereof.
       Upon such demand, delivery of such representation prior to the delivery
       of any Common Stock issued upon exercise of an Option and prior to the
       expiration of the Option Term shall be a condition precedent to the right
       of the Participant or such other person to purchase any Common Stock. In
       the event certificates for Common Stock are delivered under the Plan with
       respect to which such an investment representation has been obtained, the
       Administrative Committee may cause a legend or legends to be placed on
       such certificates to make appropriate reference to such representations
       and to restrict transfer in the absence of compliance with applicable
       federal or state securities laws.

    (j) OTHER OPTION PROVISIONS. The Administrative Committee may require a
       Participant to agree, as a condition to receiving an Option under the
       Plan, that part or all of any Options previously granted to such
       Participant under the Plan be terminated.

    6.5  EXERCISE OF OPTIONS.

    An Option shall be exercised by the delivery to the Corporation during the
Option Term of (x) written notice of intent to purchase a specific number of
Shares subject to the Option and (y) payment in full of the Option Price of such
specific number of Shares.

SECTION 7.  GENERAL PROVISIONS.

    7.1  GENERAL CREDITOR STATUS.

    Participants shall have no right, title, or interest whatsoever in or to any
investments which the Corporation may make to aid it in meeting its obligations
under the Plan. Nothing contained in the Plan, and no action taken pursuant to
its provisions, shall create or be construed to create a trust of any kind, or a
fiduciary relationship between the Corporation and any Participant, Beneficiary,
legal representative or any other person. To the extent that any person acquires
a right to receive payments from the Corporation under the Plan, such right
shall be no greater than the right of an unsecured general creditor of the
Corporation. All payments to be made hereunder shall be paid from the general
funds of the Corporation and no special or separate fund shall be established
and no segregation of assets shall be made to assure payment of such amounts
except as expressly set forth in the Plan; PROVIDED, HOWEVER, that in its sole
discretion, the Administrative Committee may authorize the creation of trusts or
other arrangements to

                                      C-7
<PAGE>
meet the obligations created under the Plan to deliver Common Stock; PROVIDED,
FURTHER, HOWEVER, that, unless the Administrative Committee otherwise determines
with the consent of the affected Participant, the existence of such trusts or
other arrangements shall be consistent with the "unfunded" status of the Plan.

    7.2  CERTAIN ADJUSTMENTS TO SHARES.

    In the event of any change in the Common Stock by reason of any stock
dividend, recapitalization, reorganization, spin-off, split-off, merger,
consolidation, stock split, reverse stock split, combination or exchange of
shares, or any rights offering to purchase Common Stock at a price substantially
below fair market value, or of any similar change affecting the Common Stock of
or by the Corporation, the number and kind of Shares available for Options under
the Plan and the Option Price per Share thereof shall be appropriately adjusted
consistent with such change in such manner as the Administrative Committee may
deem equitable to prevent substantial dilution or enlargement of the rights
granted to, or available for, the Participants hereunder. The Administrative
Committee shall give notice to each Participant of any adjustment made pursuant
to this Section and, upon notice, such adjustment shall be effective and binding
for all purposes of the Plan.

    7.3  SUCCESSOR CORPORATION.

    The obligations of the Corporation under the Plan shall be binding upon any
successor corporation or organization resulting from the merger, consolidation
or other reorganization of the Corporation, or upon any successor corporation or
organization succeeding to substantially all of the assets and business of the
Corporation. The Corporation agrees that it will make appropriate provision for
the preservation of Participants' rights under the Plan in any agreement or plan
which it may enter into or adopt to effect any such merger, consolidation,
reorganization or transfer of assets.

    7.4  NO CLAIM OR RIGHT UNDER THE PLAN.

    Neither the Plan nor any action taken thereunder shall be construed as
giving any director or Advisory Board member any right to a continuation of
membership on the Board or the Advisory Board, as applicable.

    7.5  OPTIONS NOT TREATED AS COMPENSATION UNDER BENEFIT.

    No Option shall be considered as compensation under any employee benefit
plan of the Corporation, except as specifically provided in any such plan or as
otherwise determined by the Board.

    7.6  LISTING AND QUALIFICATION OF COMMON STOCK.

    The Corporation, in its discretion, may postpone the issuance or delivery of
Common Stock upon any exercise of an Option until completion of such stock
exchange listing or other qualification of such shares under any state or
federal law, rule or regulation as the Corporation may consider appropriate, and
may make such representations and furnish such information as it may consider
appropriate in connection with the issuance or delivery of the Shares in
compliance with applicable laws, rules and regulations.

    7.7  WITHHOLDING TAXES.

    The Corporation may make such provisions and take such steps as it may deem
necessary or appropriate for the withholding of all federal, state and local
taxes required by law to be withheld with respect to Options granted pursuant to
the Plan including, but not limited to (i) accepting a remittance from the
Participant in cash, or in the Administrative Committee's discretion in Mature
Shares, (ii) deducting the amount required to be withheld from any other amount
then or thereafter payable by the Corporation to a Participant, Beneficiary or
legal representative or from any Shares due to the Participant

                                      C-8
<PAGE>
under the Plan, (iii) requiring a Participant, Beneficiary or legal
representative to pay to the Corporation the amount required to be withheld as a
condition of releasing Common Stock or (iv) any combination of the foregoing. In
addition, subject to such rules and regulations as the Administrative Committee
shall from time to time establish, Participants shall be permitted to satisfy
federal, state and local taxes, if any, imposed upon the payment of Options in
Common Stock at a rate up to such Participant's maximum marginal tax rate with
respect to each such tax by (i) irrevocably electing to have the Corporation
deduct from the number of Shares otherwise deliverable in payment of an Option
such number of Shares as shall have a value equal to the amount of tax to be
withheld, (ii) delivering to the Corporation such portion of the Common Stock
delivered in payment of the Option as shall have a value equal to the amount of
tax to be withheld, or (iii) delivering to the Corporation such number of Mature
Shares or combination of Mature Shares and cash as shall have a value equal to
the amount of tax to be withheld.

    7.8  NON-TRANSFERABILITY/DESIGNATION AND CHANGE OF BENEFICIARY.

    (a) An Option granted hereunder shall not be assignable or transferable
       other than by will or by the laws of descent and distribution and may be
       exercised during the Participant's lifetime only by the Participant or
       his or her guardian or legal representative, except that a Participant
       may, if permitted by the Administrative Committee, in its discretion,
       transfer an Option, or portion thereof, to one or more members of the
       Participant's Immediate Family.

    (b) Each Participant shall file with the Administrative Committee a written
       designation of one or more persons as the Beneficiary who shall be
       entitled to receive the amount, if any, payable under the Plan upon his
       or her death. A Participant may, from time to time, revoke or change his
       or her Beneficiary by filing a new designation with the Administrative
       Committee. The last such designation received by the Administrative
       Committee shall be controlling; PROVIDED, HOWEVER, that no designation,
       or change or revocation thereof, shall be effective unless received by
       the Administrative Committee prior to the Participants' death, and in no
       event shall it be effective as of a date prior to such receipt.

    7.9  PAYMENTS TO PERSONS OTHER THAN A PARTICIPANT.

    If the Administrative Committee shall find that any person to whom any
amount is payable under the Plan is unable to care for his or her affairs
because of illness or accident, or is a minor, or has died, then any payment due
to such person or his or her estate (unless a prior claim therefor has been made
by a duly appointed legal representative), may, if the Administrative Committee
so direct the Corporation, be paid to his or her spouse, a child, a relative, an
institution maintaining or having custody of such person, or any other person
deemed by the Administrative Committee to be a proper recipient on behalf of
such person otherwise entitled to payment. Any such payment shall be a complete
discharge of the liability of the Administrative Committee and the Corporation
thereof.

    7.10  NO LIABILITY OF ADMINISTRATIVE COMMITTEE MEMBERS.

    No member of the Administrative Committee shall be personally liable by
reason of any contract or other instrument executed by such member or on his or
her behalf in his or her capacity as a member of the Administrative Committee
nor for any mistake of judgment made in good faith, and the Corporation shall
indemnify and hold harmless each employee, officer or director of the
Corporation to whom any duty or power relating to the administration or
interpretation of the Plan may be allocated or delegated, against any cost or
expense (including counsel fees) or liability (including any sum paid in
settlement of a claim with the approval of the Board of Directors) arising out
of any act or omission to act in connection with the Plan unless arising out of
such person's own fraud or bad faith. The indemnification provided for in this
Section 7.10 shall be in addition to any rights of indemnification such
Administration Committee member has as a director of officer pursuant to law,
under the Certificate of Incorporation or By-Laws of the Corporation.

                                      C-9
<PAGE>
    7.11  AMENDMENT OR TERMINATION.

    Except as to matters that in the opinion of the Corporation's legal counsel
require stockholder approval, any provision of the Plan may be modified as to a
Participant by an individual agreement approved by the Administrative Committee.
The Board may, with prospective or retroactive effect, amend, suspend or
terminate the Plan or any portion thereof at any time; PROVIDED, HOWEVER, that
(i) no amendment that would materially increase the cost of the Plan to the
Corporation may be made by the Board without the approval of the stockholders of
the Corporation and (ii) no amendment, suspension or termination of the Plan
shall deprive any Participant of any rights to Options previously made under the
Plan without his or her written consent. Subject to earlier termination pursuant
to the provisions of this Section, and unless the stockholders of the
Corporation shall have approved an extension of the Plan beyond such date, no
further Options shall be made under the Plan after the tenth (10th) anniversary
of the Effective Date of the Plan specified in Section 7.15 hereof.

    7.12  UNFUNDED PLAN.

    The Plan is intended to constitute an unfunded deferred compensation
arrangement.

    7.13  GOVERNING LAW.

    The Plan shall be governed by and construed in accordance with the laws of
the State of Maryland, without reference to the principles of conflicts of law
thereof.

    7.14  NON-UNIFORM DETERMINATIONS.

    The Administrative Committee's determinations under the Plan need not be
uniform and may be made by the Administrative Committee selectively among
persons who receive, or are eligible to receive Discretionary Options, whether
or not such persons are similarly situated. Without limiting the generality of
the foregoing, the Administrative Committee shall be entitled, to enter into
non-uniform and selective Option Agreements as to (a) the identity of the
Participant, (b) the terms and provisions of Options, and (c) the treatment of
termination of service.

    7.15  EFFECTIVE DATE.

    The Plan is effective September 11, 2000.

    7.16  NO ILLEGAL TRANSACTIONS.

    The Plan and all Options granted pursuant to it are subject to all
applicable laws and regulations. Notwithstanding any provision of the Plan or
any Option, Participants shall not be entitled to exercise or receive benefits
under, any Option, and the Corporation shall not be obligated to deliver any
Shares or deliver any benefits to a Participant, if such exercise or delivery
would constitute a violation by the Participant or the Corporation of any
applicable law or regulation.

    7.17  SEVERABILITY.

    If any part of the Plan is declared by any court of governmental authority
to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate
any other part of the Plan. Any Section or part of a Section so declared to be
unlawful or invalid shall, if possible, be construed in manner which will give
effect to the terms of such Section to the fullest extent possible while
remaining lawful and valid.
