executed proxies received prior to or at the Special Meeting, and not revoked,

Meeting, which are to come before the Special Meeting. If any other matters are
properly presented at the Special Meeting for action, the persons named in the
enclosed form of proxy and acting thereunder will have the discretion to vote on
such matters in accordance with their best judgment.

before it is voted. Proxies may be revoked (i) by filing with the Board of
Directors of Cali at or before the Special Meeting a written notice of
revocation bearing a later date than the proxy, (ii) by duly executing a
subsequent proxy relating to the same shares of Cali Common Stock and delivering
it to the Board of Directors of Cali at or before the Special Meeting or (iii)
by attending the Special Meeting and voting in person (although attendance at
the Special Meeting will not in and of itself constitute revocation of a proxy).

Directors, Cali Realty Corporation, 11 Commerce Drive, Cranford, NJ 07016.
 
    No persons have been authorized to give any information or to make any

Recommendation of the Board of Directors.....  The Board of Directors has unanimously
                                               approved the Contribution and Exchange
                                               Agreement and the Mack Combination and
                                               recommends that the holders of Common Stock
                                               vote FOR its approval and adoption. The Board
                                               of Directors believes that the terms of the
                                               Contribution and Exchange Agreement and the
                                               Mack Combination are fair to, and in the best
                                               interests of Cali, CRLP and its shareholders.
                                               For a discussion of factors considered by the
                                               Board of Directors in reaching its decision,
                                               see "Proposal One--The Mack Combination." The
                                               Board of Directors also has unanimously
                                               approved the Amendment and recommends that
                                               the holders of Common Stock vote FOR its
                                               approval and adoption. The Board of Directors
                                               further has unanimously approved the
                                               amendments to the Employee and Director Stock
                                               Option Plans and recommends that the holders
                                               of Common Stock vote FOR their approval and
                                               adoption.

    At the Special Meeting, the Cali shareholders will: (1) consider and vote

Mack will contribute certain properties and interests in certain properties,
ground leases and 100 percent of the interests in the entities owning certain
properties (collectively the "Mack Properties") to CRLP or its designated
subsidiaries, and pursuant to which Cali and CRLP will exchange with Mack a
combination of cash, assumption of debt, common and preferred operating
partnership units in CRLP and warrants to acquire common operating partnership

amendment to the Employee Stock Option Plan to increase the number of shares
authorized thereunder by 2,200,000, from 2,780,188 to 4,980,188, (4) consider
and vote upon two amendments to the Director Stock Option Plan to (a) increase
the number of shares authorized thereunder by 200,000, from 200,000 to 400,000
and (b) to provide for the participation thereunder of non-employee members of
the Advisory Board, including a provision that a member of the Board of
Directors who resigns as a director 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 of Directors for purposes
of determining the exercise period of prior grants under the Director Stock
Option Plan, and (5) transact such other business relating thereto as may
properly come before the Special Meeting. Approval of the Amendment is
conditioned upon approval of the Mack Combination.
 
    The Board of Directors has determined the Mack Combination, the Amendment
and the amendments to the Employee and Director Stock Option Plans to be fair to
and in the best interests of Cali's shareholders, has unanimously approved the
Mack Combination, the Amendment and the amendments to the Employee and Director
Stock Option Plans and recommends a vote for approval of the Mack Combination,
the Amendment and the amendments to the Employee and Director Stock Option
Plans.
 
RECORD DATE; VOTING AT THE MEETING
 
    On the Record Date, November 4, 1997, there were 49,664,622 shares of Common
Stock outstanding. Each holder of record of Common Stock on the Record Date is
entitled to cast one vote per share of Common Stock, exercisable in person or by
a properly executed proxy, upon each matter properly submitted for the vote of
the shareholders at the Special Meeting. A majority of the shares of Common
Stock outstanding, represented in person or by proxy, will constitute a quorum
for the transaction of business at the Special Meeting. Abstentions and broker
non-votes will be treated as shares that are present and entitled to vote for
the purpose of determining a quorum.
 
    The approval and adoption of Proposals Nos. 1, 3 and 4 require the
affirmative vote of a majority of the votes cast at the Special Meeting,
assuming a quorum is present. The affirmative vote of at least two-thirds of the
outstanding shares of Common Stock is required to approve the Amendment
contained in Proposal No. 2. For purposes of satisfying this vote requirement,
abstentions from voting and broker non-votes on any Proposal will have the
effect of votes against such Proposal, but a failure to vote by not returning a
proxy will have no effect on any Proposal except the Amendment contained in
Proposal No. 2, as to which it will have the effect of a vote against such
Proposal.
 
    Approval of postponement or adjournment of the Special Meeting requires the
affirmative vote of a majority of the shares of the Common Stock voting at the
Special Meeting. For purposes of satisfying this vote requirement, failure to
vote, an abstention from voting and a broker non-vote will have the effect of
votes against postponement or adjournment. If shareholders approve such an
adjournment or postponement, the Special Meeting could be postponed or adjourned
in order to permit further solicitation of proxies if there are not sufficient
votes at the time of the Special Meeting to approve the Mack Combination.

PROXIES
 
    Shares of Common Stock represented by properly executed proxies received at
or prior to the Special Meeting that have not been revoked will be voted at the
Special Meeting in accordance with the instructions contained therein. Shares of
Common Stock represented by properly executed proxies for which no instruction
is given will be voted "FOR" approval of the Proposals. Cali's shareholders are
requested to complete, sign, date and promptly return the enclosed proxy card in
the postage prepaid envelope provided for this purpose to ensure that their
shares are voted. A shareholder may revoke a proxy any time before it is voted
by submitting at any time prior to the Special Meeting a later-dated proxy with
respect to the same shares, by delivering a written notice of revocation to the
Secretary of Cali at any time prior to such Special Meeting or by attending the
Special Meeting and voting in person. Mere attendance at the Special Meeting
will not in and of itself revoke a proxy.
 
    If the Special Meeting is postponed or adjourned for any reason, including
further solicitation of proxies, at any subsequent reconvening of the Special
Meeting all proxies will be voted in the same manner as such proxies would have
been voted at the original convening of the Special Meeting (except for any
proxies that have theretofore effectively been revoked or withdrawn).
 
    Cali has retained MacKenzie Partners, Inc. (the "Solicitation Agent") to
solicit proxies. The Solicitation Agent may contact Cali's shareholders. The
Solicitation Agent will receive a fee of approximately $12,000 for such
services, plus reimbursement of out-of-pocket expenses. The directors and
officers of Cali and their affiliates may also solicit proxies by telephone,
telegram or personal contact, and such persons will receive no additional
compensation for such services. Copies of solicitation materials will be
furnished to fiduciaries, custodians and brokerage houses for forwarding to
beneficial owners of Cali shares held in their name. Cali will bear the cost of
preparing and mailing proxy materials in connection with the Special Meeting and
the solicitation of proxies, the cost of commission filing fees and the printing
costs in connection with this Proxy Statement.

                       PROPOSAL ONE--THE MACK COMBINATION
 
REASONS FOR THE MACK COMBINATION; RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors has unanimously determined the Mack Combination to be
fair to and in the best interests of the shareholders of Cali and has
recommended that the shareholders approve the Mack Combination. In reaching its
conclusion to recommend approval of the Mack Combination, the Board of Directors
considered, without assigning relative weight to, the following factors:
 
        (i) After the Mack Combination, Cali will become one of the largest
    equity REITs in the country, with 186 properties totaling approximately 21.5
    million square feet in ten states, serving approximately 2,100 tenants. In
    New Jersey alone, Cali will own approximately eight percent of all office
    space, with over 11 million square feet. The Board of Directors believes
    that the Mack Combination will solidify Cali's position as the dominant
    super-regional office REIT in the Northeast, will provide Cali with new
    strategic positions in the Southwest for future growth opportunities and
    will further enhance Cali's access to capital.
 
        (ii) The Mack Combination will increase Cali's asset and capital base
    and diversify its sources of revenue. While the Board of Directors
    recognizes that increased profitability does not necessarily result from
    increased size, the Board of Directors believes Cali's increased size should
    also further enhance its access to capital and reduce its costs of capital.
 
       (iii) The closing of the Mack Combination will provide Cali with
    considerable geographic diversity, making Cali a significant player in key
    markets in the southwestern United States.
 
        (iv) The Mack Combination is expected to be accretive and, therefore,
    economically advantageous to Cali's current shareholders.
 
        (v) The Mack Combination will add over 1,000 tenants to Cali's tenant
    base, for a combined total of approximately 2,100 tenants. This adds to the
    diversity and stability of Cali's portfolio.
 
        (vi) The Mack Combination will bring together some of the most
    well-known and respected names in the real estate business.
 
       (vii) The receipt of a fairness opinion from Cali's financial advisor,
    Prudential Securities Incorporated. See "Proposal One--The Mack
    Combination--Fairness Opinion."
 
TERMS OF THE MACK COMBINATION
 
    Subject to the terms and conditions of the Contribution and Exchange
Agreement, Mack will contribute the Mack Properties to CRLP or its designated
subsidiaries and will cause certain of its key executives to become part of the
management of Cali.
 
    In consideration of Mack's contributions set forth in the previous
paragraph, Cali and CRLP collectively have agreed to exchange with Mack the
following consideration:
 
        (i) $468,958,000 in cash to Mack;
 
        (ii) $299,737,000 by CRLP or its designated subsidiaries acquiring
    properties subject to mortgage indebtedness in such amount;
 
       (iii) the issuance to Mack or Mack's designees of 3,972,318 common
    operating partnership interests (the "Common Units") in CRLP, redeemable,
    after one year, for an equal number of shares of Common Stock. A portion of
    such Common Units may be contingent, non-participating Common Units (the
    "Contingent Units") which will convert, in whole or in part, into ordinary
    Common Units upon the satisfaction within two years from the consummation of
    the Mack Combination of certain conditions relating to the Mack Properties.
    Until such conversion, the Contingent Units shall not be entitled to any
    economic, voting or other rights associated with the ordinary Common Units;
 
                                       9
<PAGE>
        (iv) the issuance to Mack or Mack's designees of 250,256 cumulative
    preferred operating partnership interests (the "Preferred Units") in CRLP
    composed of (a) approximately 210,256 Preferred Units immediately
    convertible at the option of the holder into approximately 6,067,994 Common
    Units, which Common Units shall be redeemable for 6,067,994 shares of Common
    Stock after three years from the closing of the Mack Combination (the
    "Series B Preferred Units") and (b) approximately 40,000 Preferred Units
    immediately convertible at the option of the holder into approximately
    1,154,401 Common Units, which Common Units shall be redeemable for 1,154,401
    shares of Common Stock after one year from the closing of the Mack
    Combination (the "Series A Preferred Units"). Currently, the 250,256
    Preferred Units would convert into 7,222,395 Common Units, and such Common
    Units would currently redeem into 7,222,395 shares of Common Stock. The
    Common Units and the Preferred Units are collectively referred to herein as
    the "Units". The quarterly distribution on each Preferred Unit will be paid
    in an amount equal to the greater of (i) $16.88 or (ii) the quarterly
    distribution attributable to a Preferred Unit if such unit had been
    converted into Common Units, subject to customary anti-dilution adjustments.
    Each Preferred Unit shall have a stated value equal to $1,000.00 (the
    "Stated Value"). Cali shall have the right to cause the conversion of any or
    all of the Preferred Units into Common Units, at any time after the seven
    and one-half (7 1/2) year anniversary of the date of the closing of the Mack
    Combination at their Stated Value, plus accrued but unpaid distributions,
    divided by $34.65 per share (subject to customary anti-dilution adjustments)
    (the "Conversion Price"); provided, however, that Cali may only exercise
    such mandatory conversion if, for twenty (20) trading days within the thirty
    (30) consecutive trading days immediately preceding such conversion date,
    the closing price of the Common Stock equals or exceeds $34.65, subject to
    customary anti-dilution adjustments. The Preferred Units will contain anti-
    dilution protection and have voting rights on any vote of limited partners
    as if the Preferred Units were converted to Common Units; and
 
        (v) the issuance to Mack or Mack's designees of 2,000,000 warrants to
    purchase an equal number of Common Units (the "Warrants"). The Warrants
    shall be exercisable at any time after the first anniversary of the closing
    of the Mack Combination for a period of four (4) years thereafter at a price
    of $37.80 per Common Unit, subject to customary anti-dilution adjustments.
    Any Common Units received upon exercise of the Warrants shall be immediately
    redeemable into Common Stock.
 
    Upon the consummation of the Mack Combination, the composition of the Board
of Directors of Cali will change. Three (3) of the Board of Directors' thirteen
(13) members shall be new members designated by Mack. The Mack designees shall
be William L. Mack, Earle I. Mack and Mitchell E. Hersh, who shall be deemed to
be "inside" members of the Board of Directors because of their relationship with
management. William L. Mack and Earle I. Mack will be classified as Class II
directors whose terms shall expire in the year 1999 and Mitchell E. Hersh will
be classified as a Class III director whose term shall expire in the year 2000.
The parties have agreed that if any inside board member designated by Mack shall
withdraw for any reason, Mack shall have the right to designate such withdrawing
director's replacement. Three (3) members of the Board of Directors shall be
designated by Cali and shall be deemed to be "inside" members of the Board of
Directors because of their relationship with management. The Cali designees
shall be current members of the Board of Directors and shall be John J. Cali,
who shall remain Chairman of the Board of Directors, Thomas A. Rizk and Robert
F. Weinberg. The parties have agreed that if any inside Board member designated
by Cali shall withdraw for any reason, the remaining Cali designated inside
Board members, on behalf of Cali, shall have the right to designate such
withdrawing director's replacement. The remaining seven (7) directors shall be
deemed to be independent outside directors. They shall include three (3)
existing independent members of Cali's Board of Directors: Brendan T. Byrne,
Irvin D. Reid and Alan G. Philibosian, and four (4) new independent members to
be selected by Mack and reasonably approved by Cali. It is anticipated that
these four new independent members will be Paul A. Nussbaum, Vincent Tese,
Jeffrey B. Lane and Martin D. Gruss. Brendan T. Byrne and Vincent Tese, Jeffrey
B. Lane and Martin D. Gruss, if selected, shall be classified as Class I
directors, Alan G. Philibosian and Paul A. Nussbaum, if selected, shall be
classified as Class II directors and Irvin D. Reid shall remain classified as a
 
                                       10
<PAGE>
Class III director. The terms of Class I directors will expire in 1998; the
terms of Class II directors will expire in 1999; and the terms of Class III
directors will expire in 2000. Kenneth A. DeGhetto, Alan Turtletaub, James W.
Hughes, Brad W. Berger, Angelo R. Cali and Brant Cali shall resign from the
Board of Directors at the closing of the Mack Combination and become members of
the Advisory Board (as described below).
 
    After the consummation of the Mack Combination, the Board of Directors shall
create an Executive Committee. William L. Mack will serve as Chairman of the
Executive Committee, which will consist of William L. Mack, Mitchell E. Hersh,
Thomas A. Rizk and John J. Cali. John J. Cali and Thomas A. Rizk (with respect
to themselves), on the one hand, and William L. Mack (with respect to himself
and Mitchell E. Hersh), on the other hand, shall have the right to appoint a
replacement for any Executive Committee member who shall withdraw from the
Executive Committee. See "Description of the Contribution and Exchange
Agreement--Directors and Officers".
 
    The Board of Directors has created an Advisory Board comprised of certain
former members of the Board of Directors to assist the Board of Directors.
Non-employee members of the Advisory Board shall be entitled to participate in
the Director Stock Option Plan, subject to shareholder approval of the amendment
to the Director Stock Option Plan providing for the same. Upon the consummation
of the Mack Combination and simultaneously with their appointment to the
Advisory Board, Kenneth A. DeGhetto, Alan Turtletaub, James W. Hughes and Angelo
R. Cali shall each be granted an option to purchase 10,000 shares of Common
Stock at its fair market value on the date of grant. Each option shall vest and
become exercisable on the earlier of (i) the first anniversary of the grant
date, provided the Advisory Board member remains in continuous service of the
Advisory Board or the Board of Directors during such period or (ii) upon the
Advisory Board member's termination of service on the Advisory Board or Board of
Directors due to retirement, death or disability. In addition, members of the
Advisory Board shall be compensated for their service on the Advisory Board in
the same amounts they were receiving as members of the Board of Directors until
the expiration date of each of their current terms on the Board of Directors in
the absence of the Mack Combination. Martin Berger and Edward Leshowitz are
current members of the Advisory Board and shall also each be granted an option
to purchase 10,000 shares of Common Stock at its fair market value on the date
of grant. In addition, each non-employee director shall be granted an option to
purchase 10,000 shares of Common Stock at its fair market value on the date of
grant upon the consummation of the Mack Combination.
 
CONDITIONS TO CONSUMMATION OF THE MACK COMBINATION
 
    The obligations of CRLP, Cali and Mack to close the Mack Combination are
conditioned, among other things, upon (i) approval of the Contribution and
Exchange Agreement by Cali's shareholders, (ii) the representations and
warranties of Cali, CRLP and Mack contained in the Contribution and Exchange
Agreement being true and correct in all material respects as of the closing of
the Mack Combination, (iii) performance by each of Cali, CRLP and Mack of their
respective obligations required to be performed under the Contribution and
Exchange Agreement on or prior to the closing of the Mack Combination, (iv)
receipt by Mack of the requisite consents and approvals from certain necessary
partners and third parties in order to contribute and convey the Mack Properties
and (v) neither CRLP nor Mack terminating the Contribution and Exchange
Agreement pursuant to the terms thereof. See "Description of the Contribution
and Exchange Agreement--Conditions Precedent to Closing the Mack Combination"
and "--Termination."
 
EFFECT OF THE MACK COMBINATION
 
    The Warrants and the Units issued pursuant to the Mack Combination represent
the equivalent of 13,194,713 shares of Common Stock, which shares may be
purchased by Mack upon the exercise of the Warrants and the conversion and/or
redemption of the Units, such number equaling 26.6 percent of the
 
                                       11
<PAGE>
49,664,622 shares of Common Stock currently outstanding and 24.5 percent of the
shares of Common Stock currently outstanding, assuming redemption of all
outstanding Units.
 
    Pursuant to the Amended and Restated Agreement of Limited Partnership of
CRLP, Cali shall not, without the prior consent of holders of at least
eighty-five percent (85%) of the ownership interests in CRLP, taken as a single
class, on behalf of CRLP, undertake any of the following actions: (a) cause or
permit the merger of CRLP into any entity pursuant to a transaction in which
CRLP is not the surviving entity, or take any other action which may have the
effect of the foregoing; (b) dissolve, liquidate or wind-up CRLP; or (c) convey
or otherwise transfer all or substantially all of CRLP's assets in one or a
series of transactions.
 
    At present, Cali owns 92.4 percent of the ownership interest in CRLP and
certain limited partners of CRLP, in the aggregate, own the remaining 7.6
percent. Accordingly, Cali can effectuate the above provisions without the
consent of any of the limited partners of CRLP. After the consummation of the
Mack Combination, Cali's percentage ownership interest in CRLP will decrease to
76.5 percent and the aggregate limited partners interest will increase to 23.5
percent. Thus, the consent of the limited partners holding at least an 8.5
percent interest in CRLP will be required to effect the aforementioned
transactions, which number shall decrease proportionately as Cali's percentage
ownership increases through subsequent issuances of public stock by Cali. It
shall remain necessary for the limited partners to vote on such transactions
until Cali's percentage ownership interest in CRLP equals or exceeds 85 percent.
 
ACCOUNTING TREATMENT
 
    The Mack Combination will be accounted for as a purchase. See Cali's pro
forma financial statements included elsewhere in this Proxy Statement.
 
FAIRNESS OPINION
 
    Cali has retained Prudential Securities Incorporated ("Prudential
Securities") to provide financial advisory services and evaluate from a
financial perspective the fairness to Cali of the consideration to be paid to
Mack in connection with the Mack Combination.
 
    On September 18, 1997, Prudential Securities delivered its written opinion
(the "Prudential Securities Opinion") to the Board of Directors of Cali stating
that, as of such date and subject to certain assumptions, limitations and other
matters as set forth in the Prudential Securities Opinion, the consideration to
be paid by Cali in connection with the Mack Combination is fair, from a
financial point of view, to Cali. At the meeting of the Board of Directors of
Cali held on September 18, 1997, Prudential Securities presented certain
financial analyses accompanied by written materials (which written materials
were delivered prior to the meeting) in connection with the delivery of the
Prudential Securities Opinion. Members of the Board of Directors of Cali were
present (via teleconference) at the meeting and had an opportunity to ask
questions of Prudential Securities. Prudential Securities discussed with the
Board of Directors of Cali the information in the report and the financial data
and other factors considered by Prudential Securities in conducting its
analyses, all of which are summarized herein.
 
    The full text of the Prudential Securities Opinion, which sets forth
assumptions made, matters considered and limits on the review undertaken is
attached hereto as Annex 1 and is incorporated herein by reference. The
description of the Prudential Securities Opinion set forth herein is qualified
in its entirety by reference to the full text of the Prudential Securities
Opinion. Cali's shareholders are urged to read the Prudential Securities Opinion
in its entirety.
 
    THE PRUDENTIAL SECURITIES OPINION IS ADDRESSED TO THE BOARD OF DIRECTORS OF
CALI AND ADDRESSES ONLY THE FAIRNESS, AS OF THE DATE OF SUCH OPINION, FROM A
FINANCIAL POINT OF VIEW, OF THE MACK COMBINATION CONSIDERATION AND DOES NOT
ADDRESS THE MERITS OF THE UNDERLYING DECISION BY CALI TO ENGAGE IN THE MACK
COMBINATION AND DOES NOT CONSTITUTE, NOR SHOULD IT BE
 
                                       12
<PAGE>
CONSTRUED AS, A RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER
SHOULD VOTE AT THE SPECIAL MEETING. THE CONSIDERATION IN CONNECTION WITH THE
MACK COMBINATION WAS DETERMINED ON THE BASIS OF NEGOTIATIONS BETWEEN CALI AND
MACK AND WAS APPROVED BY THE BOARD OF DIRECTORS OF CALI.
 
    In conducting its analysis and arriving at the Prudential Securities
Opinion, Prudential Securities reviewed such information and considered such
financial data and other factors as Prudential Securities deemed relevant under
the circumstances, including:
 
        (i) a draft of the Contribution and Exchange Agreement dated September
    12, 1997;
 
        (ii) a draft of the audited combined financial statements for Mack for
    the year ended December 31, 1996 and a draft of the unaudited combined
    financial statements for the six months ended June 30, 1997;
 
        (iii) certain publicly available historical financial and operating data
    for Cali including, but not limited to, (a) the Annual Report on Form 10-K
    for the fiscal year ended December 31, 1996, (b) the Proxy Statement for the
    Annual Meeting of Stockholders held on May 15, 1997, (c) the Quarterly
    Reports on Form 10-Q for the quarters ended March 31, 1997 and June 30,
    1997, (d) the Registration Statement on Form S-3, file No. 333-19101, dated
    January 7, 1997 and (e) draft Form 8-K, dated September 18, 1997 relating to
    the Mack Combination;
 
        (iv) certain financial forecasts for Cali and the Mack Properties
    provided to Prudential Securities by the management of Cali;
 
        (v) historical stock market prices and trading volume for Cali's Common
    Stock;
 
        (vi) certain historical results of operations of Mack provided to
    Prudential Securities by the management of Mack;
 
        (vii) publicly available information including financial, operating and
    stock market data concerning certain companies engaged in businesses
    Prudential Securities deemed comparable to Mack or otherwise relevant to
    Prudential Securities' inquiry;
 
        (viii) the financial terms of certain recent transactions Prudential
    Securities deemed relevant;
 
        (ix) the pro forma financial impact of the Mack Combination on Cali; and
 
        (x) such other financial studies, analyses and investigations as
    Prudential Securities deemed appropriate.
 
    Prudential Securities discussed with senior management of Cali and Mack: (i)
the prospects and business plans for Cali and Mack; (ii) financial forecasts for
Cali and the Mack Properties; and (iii) such other matters as Prudential
Securities deemed relevant. The Prudential Securities Opinion is necessarily
based upon information available to Prudential Securities and upon economic,
financial and market conditions as they existed and can only be evaluated as of
the date of the Prudential Securities Opinion. In connection with its review and
analysis in arriving at the Prudential Securities Opinion, Prudential Securities
assumed and relied upon the accuracy and completeness of the publicly available
information and all information provided or otherwise made available to
Prudential Securities, and did not undertake to verify independently any such
information. Prudential Securities neither made nor obtained any independent
evaluation of such information or any independent valuation or appraisal of the
assets or liabilities of either Cali or Mack. With respect to the pro forma
financial information regarding Cali and the financial forecasts for the Mack
Properties, respectively, Prudential Securities assumed that such information
was reasonably prepared and reflects the best currently expected future
performance of Cali and Mack. Prudential Securities has not undertaken any
independent analysis to verify the reasonableness of the assumptions underlying
such forecasts.
 
                                       13
<PAGE>
    Prudential Securities assumed that the draft Contribution and Exchange
Agreement reviewed by it will conform in all material respects to the document
when in final form, that the disclosure schedules and due diligence contemplated
by that agreement will not identify any adverse condition, and that the Mack
Combination will be consummated substantially as contemplated by the draft
Contribution and Exchange Agreement.
 
    Subject to the foregoing, the following is a summary of the material
financial analyses performed by Prudential Securities in arriving at the
Prudential Securities Opinion.
 
    In the following analyses, Prudential Securities calculated the transaction
offer value based on Prudential Securities' valuation of the consideration in
connection with the Mack Combination. Using publicly available share price
information for Cali Common Stock, Prudential Securities independently valued
the Common Units, Preferred Units and Warrants; Prudential Securities then added
the cash and the value of the debt to be assumed by Cali to arrive at the
Transaction Offer Value.
 
    ANALYSIS OF SELECTED COMPARABLE PUBLICLY TRADED COMPANIES.  Using publicly
available information and estimates of future financial results published by
FIRST CALL, an industry service provider of earnings estimates based on an
average of earnings estimates published by various investment banking firms
("First Call") and taken from Prudential Securities Equity Research, Prudential
Securities compared certain financial and operating information and ratios for
Mack with the corresponding financial and operating information for a group of
publicly traded companies engaged primarily in the ownership, management,
operation and acquisition of office properties which Prudential Securities
deemed to be reasonably comparable to Mack. For the purpose of its analyses, the
following companies were used as comparable companies to Mack: Beacon Properties
Corporation, CarrAmerica Realty Corporation, Cousins Properties Inc., Equity
Office Properties Trust, Highwoods Properties, Inc., Prentiss Properties Trust,
Reckson Associates Realty Corporation and Spieker Properties, Inc.
(collectively, the "Mack Comparable Companies").
 
    Prudential Securities' calculations resulted in the following relevant
ranges for the Mack Comparable Companies and for Mack as of September 15, 1997:
a range of equity market value as a multiple of estimated 1997 Funds from
Operations of 12.1x to 18.6x, with a mean of 14.5x (as compared to Mack's
implied equity value at 11.2x) and a range of equity market value as a multiple
of projected 1998 Funds from Operations of 11.0x to 16.5x with a mean of 13.0x
(as compared to Mack's implied equity value at 10.6x).
 
    None of the Mack Comparable Companies is, of course, identical to Mack.
Accordingly, a complete analysis of the results of the foregoing calculations
cannot be limited to a quantitative review of such results and involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the Mack Comparable Companies and other factors that could
affect the public trading volume of the Mack Comparable Companies, as well as
that of Mack. In addition, the multiples of market value to estimated 1997 Funds
from Operations and projected 1998 Funds from Operations for the Mack Comparable
Companies are based on projections prepared by research analysts using only
publicly available information. Accordingly, such estimates may or may not prove
to be accurate.
 
    COMPARABLE TRANSACTIONS ANALYSIS.  Prudential Securities also compared
certain financial ratios of the Mack Combination with those of other selected
mergers and strategic transactions involving REITs which Prudential Securities
deemed to be relevant. These transactions were (listed acquiror first and target
second) Highwoods Properties, Inc. and Associated Capital Properties,
Cornerstone Properties, Inc. and Dutch Institutional Holding Co., Inc, Equity
Office Properties Trust and the Prudential properties, Vornado Realty Trust and
Mendik Company, Inc., Cali Realty Corporation and Robert Martin Company, Spieker
Properties, Inc. and Mission West Properties, CarrAmerica Realty Corporation and
the Nelo/ Orchard portfolio, CarrAmerica Realty Corporation and the Peterson
portfolio, Highwoods Properties, Inc. and Crocker Realty Trust, Inc., Reckson
Associates Realty Corporation and Halpern Enterprises,
 
                                       14
<PAGE>
Highwoods Properties, Inc. and Eakin & Smith, Inc., Liberty Property Trust and
Lingerfelt Development Corporation, and Highwoods Properties, Inc. and Forsyth
Properties, Inc.
 
    Prudential Securities' calculations resulted in the following relevant
ranges for the Comparable Transactions and for the proposed Mack Combination: a
range of total transaction value (defined as total equity value plus total
indebtedness assumed) as a multiple of last twelve months Funds from Operations
plus interest expense of 9.6x to 14.5x, with a mean of 11.3x (as compared to the
proposed Mack Combination at 12.3x on a last twelve months basis and 11.3x on a
projected 1998 basis).
 
PRO FORMA CONSEQUENCES
 
    PRO FORMA COMBINATION ANALYSIS.  Prudential Securities analyzed the pro
forma effects resulting from the Mack Combination, including the potential
impact on Cali's projected stand-alone Funds from Operations per share and the
anticipated accretion (i.e., the incremental increase) to Cali's Funds from
Operations per share resulting from the Mack Combination. Based on projected
statements of operations provided by Cali management for both Cali and Mack,
each presented on a stand-alone basis, Prudential Securities observed that the
Mack Combination would be accretive to Cali's projected Funds from Operations
per share in 1998.
 
    CAPITALIZATION.  In addition, Prudential Securities compared Cali's market
capitalization as of June 30, 1997 to Cali's pro forma projected market
capitalization after giving effect to the Mack Combination based on assumptions
of Cali's management. Cali's pro forma implied market capitalization after
giving effect to the Mack Combination was calculated to be $3.47 billion. The
projected total debt to implied market capitalization was calculated to be 32.3
percent, on a pro forma basis.
 
    RELATIVE CONTRIBUTION ANALYSIS.  Prudential Securities examined Cali's and
Mack's relative contributions of projected 1998 revenue, net operating income
and Funds from Operations to the combined entity and compared this to the
percentage of post-combination Cali Common Stock that the respective current
Cali shareholders and Mack principals would hold. In performing such analysis
Prudential Securities relied upon projected stand-alone operating data for both
Cali and Mack, provided by the management of Cali. Existing Cali shareholders
and Mack principals are estimated to hold 60.0 percent and 40.0 percent
(excluding the effects of any new public equity offering) of the
post-combination shares of Cali Common Stock (on a fully-converted basis),
respectively. Cali and Mack were analyzed to have contributed 60.3 percent and
39.7 percent, respectively to the pro forma revenue of the combined entity, 61.0
percent and 39.0 percent, respectively to the pro forma net operating income of
the combined entity, and 57.0 percent and 43.0 percent, respectively to the pro
forma Funds from Operations of the combined entity for the projected year 1998.
 
    The summary set forth above does not purport to be a complete description of
the analyses performed by Prudential Securities in arriving at the Prudential
Securities Opinion. The preparation of a fairness opinion is a complex process
and is not necessarily susceptible to partial or summary description. Prudential
Securities believes that its analyses must be considered as a whole and that
selecting portions of its analyses and of the factors considered by it, without
considering all factors and analyses, could create a misleading view of the
process underlying the Prudential Securities Opinion. In its analyses,
Prudential Securities made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond Cali's, Mack's and Prudential Securities' control. Any
estimates contained in Prudential Securities' analyses are not necessarily
indicative of actual values, which may be significantly more or less favorable
than as set forth therein. Estimated values do not purport to be appraisals and
do not necessarily reflect the prices at which businesses or companies may be
sold in the future, and such estimates are inherently subject to uncertainty.
 
    The Board of Directors of Cali selected Prudential Securities to render a
fairness opinion because Prudential Securities is an internationally recognized
investment banking firm with substantial experience in transactions similar to
the Mack Combination and because it is familiar with Cali and its business.
 
                                       15
<PAGE>
Prudential Securities is continually engaged in the valuation of businesses and
their securities in connection with mergers and acquisitions, leveraged buyouts,
negotiated underwritings, secondary distributions of listed and unlisted
securities and private placements.
 
    Pursuant to an engagement letter dated August 11, 1997, Cali will pay
Prudential Securities at the closing of the Mack Combination an advisory fee
equal to 0.50 percent of the consideration (calculated pursuant to the
engagement letter) paid in connection with the Mack Combination. Cali will also
indemnify Prudential Securities and certain related persons against certain
liabilities arising out of or in conjunction with its rendering of services
under such engagement, including certain liabilities under the federal
securities law.
 
    Prudential Securities may provide financial advisory and financing services
to Cali and may receive fees for the rendering of such services. In the ordinary
course of its business, Prudential Securities may actively trade in the
securities of Cali for its own account and the account of its customers and,
accordingly, may at any time hold a long or short position in such securities.

    The Board of Directors has unanimously approved and recommends the adoption
by Cali's shareholders of an amendment to Cali's Articles of Incorporation which

Incorporation, as amended, shall read as follows:
 
              "The name of the corporation (the "Corporation") is:
                         Mack-Cali Realty Corporation"
 
    The adoption of the Amendment is conditioned upon the approval of the Mack
Combination. If the Amendment and the Mack Combination are approved by the Cali
shareholders, then the Amendment will become effective on or about the Closing
Date.
 
VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION
 
    The affirmative vote of two-thirds of the outstanding shares of Common
Stock, either in person or by proxy, is required for approval of this proposal.
Abstentions, broker non-votes and a failure to vote will have the same effect as

          PROPOSAL THREE--AMENDMENT TO THE EMPLOYEE STOCK OPTION PLAN
                        TO INCREASE THE NUMBER OF SHARES
                       AUTHORIZED FOR ISSUANCE THEREUNDER
 
    The Board of Directors and the shareholders of Cali approved the adoption of
the Employee Stock Option Plan on August 23, 1994. An aggregate of 2,780,188
shares of Cali's Common Stock are currently authorized for the issuance of
grants under the Employee Stock Option Plan, of which 714,613 shares remained
available for future grants as of October 31, 1997. The Board of Directors has
amended the Employee Stock Option Plan, subject to shareholder approval, to
increase the number of shares of Common Stock authorized for issuance of grants
under the Employee Stock Option Plan by 2,200,000 to a total of 4,980,188. Cali
intends to register the 2,200,000 share increase on Form S-8 under the
Securities Act of 1933, as amended, as soon as practicable after receiving
shareholder approval. Upon consummation of the Mack Combination, certain senior
executives of Cali will receive options under the Employee Stock Option Plan
from a pool of 1,255,000 options which will be made available and allocated
among such senior executives.
 
    The Board of Directors believes that approval of this amendment to the
Employee Stock Option Plan is in the best interests of Cali and its shareholders
because the availability of an adequate number of shares reserved for issuance
under the Employee Stock Option Plan and the ability to grant stock options and
make other stock-based awards under the Employee Stock Option Plan is an
important factor in attracting, motivating and retaining qualified personnel
essential to the success of Cali. The amendment to increase the number of shares
authorized under the Employee Stock Option Plan is designed to maintain the
approximate historical ratio of shares authorized under the Employee Stock
Option Plan to the total number of outstanding shares of Common Stock and Common
Stock equivalents in light of the number of Units and Warrants to be issued in
connection with the Mack Combination.
 
SUMMARY OF THE PROVISIONS OF THE EMPLOYEE STOCK OPTION PLAN, AS AMENDED
 
    The following summary of the Employee Stock Option Plan, as amended, is
qualified in its entirety by the specific language of the plan, a copy of which
is available to any shareholder upon request.
 
    GENERAL.  The purposes of the 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 Cali. The Employee Stock Option Plan provides for the grant of
incentive stock options, within the meaning of Section 422 of the Code to
employees of Cali and for the grant of nonstatutory stock options, stock
appreciation rights ("SARs") and shares of restricted stock ("Restricted Stock")
to employees, consultants and advisors of Cali. Currently, 1,805,919 of the
authorized but unissued shares of the Common Stock of Cali may be issued upon
the exercise of options granted pursuant to the Employee Stock Option Plan. To
date, no SARs or shares of Restricted Stock have been awarded under the Employee
Stock Option Plan. The Board has amended the Employee Stock Option Plan, subject
to shareholder approval, to increase the number of shares authorized for
issuance thereunder by 2,200,000, from 2,780,188 to 4,980,188 shares. 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 Cali, appropriate adjustments will be made to the shares
subject to the Employee Stock Option Plan and to any outstanding awards. To the
extent any outstanding option under the Employee Stock Option Plan expires or
terminates prior to its exercise in full, or if any shares of Restricted Stock
are forfeited, the shares of Common Stock no longer subject to the option or
restrictions will be returned to the Employee Stock Option Plan and made
available for future grants.
 
    ADMINISTRATION.  The Employee Stock Option Plan is administered by the
Option and Executive Compensation Committee ("the Compensation Committee") of
the Board of Directors of Cali. With respect to the participation of individuals
who are subject to Section 16 of the Securities Exchange Act of 1934 (the
"Exchange Act"), the 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 Employee Stock
 
                                       18
<PAGE>
Option Plan, the Compensation 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 Compensation 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 Cali upon the option's exercise and the other
terms and conditions of the grant. The terms and conditions of Restricted Stock
awards are also determined by the Compensation Committee. The Compensation
Committee has the responsibility to interpret the Employee Stock Option Plan and
to make determinations with respect to all awards granted under the Employee
Stock Option Plan. All determinations of the Compensation Committee are final
and binding on all persons having an interest in the Employee Stock Option Plan
or in any award made under the Employee Stock Option Plan. The costs and
expenses of administering this Employee Stock Option Plan are borne by Cali.
 
    ELIGIBILITY.  All employees, consultants and advisors (including directors
of Cali who are also employees) are eligible to participate in the Employee
Stock Option Plan. As of October 31, 1997, 242 employees, including nine
officers, three of whom are also directors of Cali, were eligible to participate
in the Employee Stock Option Plan. Non-employee directors of Cali may not
participate.
 
    TERMS AND CONDITIONS OF OPTION GRANTS.  Each option granted under the
Employee Stock Option Plan is evidenced by a written agreement between Cali and
the optionee specifying the number of shares of Cali's Common Stock subject to
the option and all of the other terms and conditions of the option, consistent
with the requirements of the Employee Stock Option Plan. The per share exercise
price of an incentive stock option may not be less than 100 percent of the fair
market value of a share of Common Stock on 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 percent of the total
combined voting power or value of all classes of stock of Cali must be at least
110 percent of the fair market value of a share of Cali's Common Stock on the
date of grant and the term of any such option cannot exceed five years.
 
    Generally, options may be exercised by the payment of the exercise price in
cash, by check, or in cash equivalents, such as through the tender of shares of
Cali's Common Stock owned by the optionee having a fair market value not less
than the exercise price, or 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, or in any combination of these methods consistent with the terms and
conditions of the applicable stock option agreement.
 
    Options granted under the Employee Stock Option Plan will become exercisable
at such times as may be specified by the Compensation Committee, and generally
become exercisable in equal installments subject to the optionee's continued
employment or service with Cali. The maximum term of options granted under the
Employee Stock Option Plan is ten years. Options are 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.
 
    TERMS AND CONDITIONS OF OTHER AWARDS.  Each SAR or Restricted Stock award
made under the Employee Stock Option Plan is also evidenced by a written
agreement between Cali 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 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 Cali, and the
per share grant price. Upon settlement of the SAR
 
                                       19
<PAGE>
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 forfeiture of the
shares and the time and manner in which the restrictions will lapse, subject to
the award holder's continued employment by Cali. Upon settlement of the
Restricted Stock award, occurring upon the lapse of the restrictions, the shares
of Common Stock subject to the award will be come 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 shareholders of
Cali do not retain, directly or indirectly, at least a majority of the
beneficial interest in the voting stock of Cali or its successor: (i) the direct
or indirect sale or exchange by the shareholders of Cali of all or substantially
all of the stock of Cali, (ii) a merger in which Cali is a party, or (iii) the
sale, exchange or transfer of all or substantially all of the assets of Cali. 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 EMPLOYEE STOCK OPTION PLAN.  Unless sooner
terminated, no awards may be granted under the Employee Stock Option Plan after
August 31, 2004. The Board of Directors may terminate or amend the Employee
Stock Option Plan at any time, but the Board of Directors may not amend the
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 Employee Stock Option Plan to Cali without
shareholder approval. No amendment may be adopted that would adversely affect an
outstanding option or award without the participant's consent.
 
    As of October 31, 1997, Cali had outstanding options to purchase an
aggregate of 1,805,919 shares of Common Stock held by 184 persons at a weighted
average exercise price of $24.28 per share. The exercise price of all options
granted under the Employee Stock Option Plan has been no less than 100 percent
of the fair market value of the Common Stock on the date of the grant as
determined in good faith by the Compensation Committee. As of October 31, 1997,
options to purchase 259,656 shares of Common Stock granted pursuant to the
Employee Stock Option Plan had been exercised and there were 714,613 shares of
Common Stock available for future grant under the Employee Stock Option Plan. By
amending the Employee Stock Option Plan to increase the share reserve by
2,200,000, there will be 2,914,613 shares of Common Stock available for future
grants under the Employee Stock Option Plan. On November 5, 1997, the closing
sales price per share of Cali's Common Stock, as reported on The New York Stock
Exchange, was $39.8125.
 
SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES OF THE 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
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 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, Cali will not be entitled to any deduction
for federal income tax purposes. If an optionee disposes of the
 
                                       20
<PAGE>
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 Cali for federal income tax
purposes, except to the extent such deduction is limited by Section 162(m) of
the Code. 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 shares are not vested and/or 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 later of (i) the date on which the shares
vest, or (ii) 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 percent of the Common Stock of Cali.) 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 Cali with respect to
the grant of a nonstatutory option or the sale of the stock acquired pursuant to
such grant. Cali 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 grant and exercise price 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. Cali 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.
 
VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION
 
    Assuming a quorum is present, the affirmative vote of a majority of the
votes cast at the Special Meeting, either in person or by proxy, is required for
approval of this proposal. Abstentions will have the same effect as a negative
vote on this proposal. Broker non-votes will have no effect on the outcome of
this proposal.
 
    THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE INCREASE IN THE
SHARE RESERVE OF THE EMPLOYEE STOCK OPTION PLAN BY 2,200,000 SHARES.

          PROPOSAL FOUR--AMENDMENTS TO THE DIRECTOR STOCK OPTION PLAN
                        TO INCREASE THE NUMBER OF SHARES
             AUTHORIZED FOR ISSUANCE THEREUNDER AND TO PROVIDE FOR
                PARTICIPATION THEREUNDER OF NON-EMPLOYEE MEMBERS
                             OF THE ADVISORY BOARD
 
    Cali has established and implemented the Director Stock Option Plan for the
benefit of eligible non-employee directors of Cali. The Director Stock Option
Plan was also approved by the Board of Directors and the shareholders of Cali on
August 23, 1994. An aggregate of 200,000 shares of Cali's Common Stock is
currently authorized for the issuance of grants under the Director Stock Option
Plan, of which 141,000 shares remained available for future grants as of October
31, 1997. The Board of Directors has amended the Director Stock Option Plan,
subject to shareholder approval, to increase the number of shares of Common
Stock of Cali authorized for the issuance of grants under the Director Stock
Option Plan by 200,000 to a total of 400,000. Cali intends to register the
200,000 share increase on Form S-8 under the Securities Act of 1933 as soon as
practicable after receiving shareholder approval. Upon consummation of the Mack
Combination, each non-employee member of the Advisory Board and each
non-employee director shall be granted an option to purchase 10,000 shares of
Common Stock at its fair market value on the date of grant, for an aggregate of
170,000 shares.
 
    The Board of Directors believes that the 200,000 share reserve increase
under the Director Stock Option Plan is in the best interests of the
shareholders and Cali because the availability of an adequate number of shares
reserved for issuance under the Director Stock Option Plan and 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 chart Cali's course towards continued growth and
financial success. The amendment to increase the number of shares authorized
under the Director Stock Option Plan is designed to maintain the approximate
historical ratio of shares authorized under the Director Stock Option Plan to
the total number of outstanding shares of Common Stock and Common Stock
equivalents in light of the number of Units and Warrants to be issued in
connection with the Mack Combination.
 
    The Board of Directors has also amended the Director Stock Option Plan,
subject to shareholder approval, to provide for the participation thereunder of
non-employee members of the Advisory Board, including a provision that a member
of the Board of Directors who resigns as a director 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 of Directors
for purposes of determining the exercise period of prior grants under the
Director Stock Option Plan.
 
    The Board of Directors believes that the participation of the non-employee
members of the Advisory Board in the Director Stock Option Plan, including the
provision that a member of the Board of Directors who resigns as a director 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 of Directors for purposes of determining the exercise period of prior
grants under the Director Stock Option Plan, is in the best interests of the
shareholders and Cali because the ability to grant options thereunder to
non-employee members of the Advisory Board is an important factor in attracting,
motivating and retaining distinguished personnel with proven ability and vision
to assist the Board of Directors by serving on the Advisory Board and chart
Cali's course towards continued growth and financial success.
 
SUMMARY OF THE PROVISIONS OF THE DIRECTOR STOCK OPTION PLAN, AS AMENDED
 
    The following summary of the Director Stock Option Plan, as amended, is
qualified in its entirety by the specific language of the Director Stock Option
Plan, a copy of which is available to any shareholder upon request.
 
                                       22
<PAGE>
    GENERAL.  The Director Stock Option Plan is designed to enable Cali to
attract and retain persons of outstanding competence to serve as members of the
Board of Directors of Cali and to provide a direct link between directors'
compensation and shareholder value. Participation in the Director's Option Plan
is currently restricted to non-employee directors and only nonstatutory options
to purchase shares of the Common Stock of Cali are granted. Currently, 47,000 of
the authorized but unissued shares of the Common Stock of Cali may be issued
upon the exercise of options granted under the Director Stock Option Plan. The
Board of Directors has amended this Plan, subject to shareholder approval, to
increase the number of shares authorized for issuance thereunder by 200,000,
from 200,000 to 400,000 shares and to provide for the participation thereunder
of non-employee members of the Advisory Board, including a provision that a
member of the Board of Directors who resigns as a director 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 of
Directors for purposes of determining the exercise period of prior grants under
the Director Stock Option Plan. The 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 Cali, appropriate adjustments will be made to the
shares of Common Stock subject to the 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 Director Stock Option Plan and made available
for future grants.
 
    ADMINISTRATION.  The Director Stock Option Plan is administered by the
Compensation Committee of the Board of Directors of Cali 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 Director Stock Option Plan are non-discretionary and are
dictated by the written terms of the Director Stock Option Plan. Under the
Director Stock Option Plan, upon an eligible director's initial election or
appointment to the Board of Directors of Cali, the director is automatically
granted a non-statutory stock option to purchase 5,000 shares of Common Stock of
Cali at its fair market value on the date of grant. The Compensation Committee
may make additional discretionary options grants to eligible directors,
consistent with the terms of the Director Stock Option Plan. All options granted
under the Director Stock Option Plan are non-statutory stock options. Subject to
certain specific limitations and restrictions set forth in the Director Stock
Option Plan, the Compensation Committee has the authority to interpret the
Director Stock Option Plan, to prescribe, amend and rescind rules and
regulations, if any, relating to the Director Stock Option Plan and to make all
determinations necessary or advisable for the administration of the Director
Stock Option Plan. The costs and expenses of administering the Director Stock
Option Plan are paid by Cali.
 
    ELIGIBILITY.  Participation in the Director Stock Option Plan is limited to
persons who serve as members of the Board of Directors of Cali and who, at the
time of the option grant, are not employees of Cali. As of October 31, 1997,
nine directors of Cali were eligible to participate in this plan. The Board of
Directors has amended the Director Stock Option Plan, subject to shareholder
approval, to provide for the participation thereunder of members of the Advisory
Board who, at the time of the option grant, are not employees of Cali, including
a provision that a member of the Board of Directors who resigns as a 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 for purposes of determining the exercise period of prior
grants under the Director Stock Option Plan.
 
    TERMS AND CONDITIONS OF OPTION GRANTS.  The 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 of Cali 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 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, or (ii) upon the director's termination of
Board of Directors
 
                                       23
<PAGE>
service due to retirement, death or disability. If a director's service is
terminated for "cause" all awards granted to the director under the 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 Director Stock Option Plan does not
provide for the vesting of outstanding options to be accelerated upon a "Change
of Control" of Cali. 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 Cali and the optionee. In addition,
the Compensation Committee may make additional discretionary option grants to
eligible directors the terms of which shall be determined by the Compensation
Committee, consistent with the provisions of the Director Stock Option Plan and
specified in a written agreement. The Board of Directors has amended the
Director Stock Option Plan, subject to shareholder approval, to provide that the
Compensation Committee may make discretionary option grants to eligible members
of the Advisory Board. Neither the existence of the Director Stock Option Plan,
nor the granting of an option thereunder, will be construed to limit, in any
way, the right of Cali or its shareholders 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 Director Stock
Option Plan shall be construed to give any director the right to a grant of an
option under the Director Stock Option Plan unless the express terms and
conditions of the Director Stock Option Plan are satisfied. Options may be
exercised by the payment of the exercise price in cash, by check, or in cash
equivalents, such as through the tender of shares of Cali's Common Stock owned
by the optionee having a fair market value not less than the exercise price, or
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, or in any
combination of these methods consistent with the terms and conditions of the
applicable stock option agreement. Options are 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 the optionee.
 
    TERMINATION OR AMENDMENT OF THE DIRECTOR STOCK OPTION PLAN.  Unless sooner
terminated, no awards may be granted under the Director Stock Option Plan after
August 31, 2004. The Board of Directors may terminate or amend the Director
Stock Option Plan at any time, but the Board of Directors may not amend the
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 Director Stock Option Plan to Cali without
shareholder approval. No amendment may be adopted that would adversely affect an
outstanding option or award without the participant's consent.
 
    As of October 31, 1997, Cali had outstanding options to purchase an
aggregate of 47,000 shares of Common Stock held by eight persons at an average
exercise price of $21.57 per share. As of October 31, 1997, options to purchase
an aggregate of 12,000 shares of Common Stock granted pursuant to the Director
Stock Option Plan had been exercised and there were 141,000 shares of Common
Stock available for future grants under the Director Stock Option Plan. By
amending the Director Stock Option Plan to increase the share reserve by
200,000, there will be 341,000 shares of Common Stock available for future
grants under the Director Stock Option Plan. On November 5, 1997, the closing
sales price per share of Cali's Common Stock, as reported on the New York Stock
Exchange, was $39.8125.
 
SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES OF THE 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 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 Cali 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.
 
                                       24

    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 Director Stock Option Plan. The tax consequences of awards made under this
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 at the Special Meeting, either in person or by proxy, is required for
approval of this proposal. Abstentions will have the same effect as a negative
vote on this proposal. Broker non-votes will have no effect on the outcome of
this vote.
 
    THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE INCREASE IN THE
SHARE RESERVE OF THE DIRECTOR STOCK OPTION PLAN BY 200,000 SHARES AND THE
PARTICIPATION THEREUNDER OF NON-EMPLOYEE MEMBERS OF THE ADVISORY BOARD.

             DESCRIPTION OF THE CONTRIBUTION AND EXCHANGE AGREEMENT
 
    The following summary of the material provisions of the Contribution and
Exchange Agreement, including the descriptions of certain provisions set forth
elsewhere in this Proxy Statement, is qualified in its entirety by reference to
the Contribution and Exchange Agreement, a copy of which has been filed with the
Securities and Exchange Commission on a Current Report on Form 8-K dated
September 19, 1997, and is incorporated herein by reference.
 
GENERAL
 
    The Mack Combination will effect the contribution of the Mack Properties by
Mack to CRLP or its designated partnership subsidiaries in exchange for certain
consideration. See "Proposal One--The Mack Combination".
 
CONSIDERATION
 
    In consideration of Mack's contribution of the Mack Properties, Cali and
CRLP collectively have agreed to exchange with Mack the following consideration:
(i) approximately $469.0 million in cash to Mack; (ii) approximately $299.7
million in assumption of debt by CRLP or its designated subsidiaries; (iii) the
issuance to Mack or Mack's designees of 3,972,318 common operating partnership
interests (the "Common Units") in CRLP, redeemable after one year, for an equal
number of shares of Common Stock, a portion of which may be Contingent Units;
(iv) the issuance to Mack or Mack's designees of 250,256 cumulative preferred
operating partnership interests in CRLP composed of (a) approximately 210,256
Series B Preferred Units immediately convertible into approximately 6,067,994
Common Units, which Common Units shall be redeemable for 6,067,994 shares of
Common Stock after three years and (b) approximately 40,000 Series A Preferred
Units immediately convertible into approximately 1,154,401 Common Units, which
Common Units shall be redeemable for 1,154,401 shares of Common Stock after one
year; and (v) the issuance to Mack or Mack's designees of 2,000,000 Warrants to
purchase an equal number of Common Units.
 
    The Preferred Units will contain anti-dilution protection and have voting
rights on any vote of limited partners as if the Preferred Units were converted
to Common Units. Currently, the 250,256 Preferred Units would convert into
7,222,395 Common Units. The quarterly distribution on each Preferred Unit will
be paid in an amount equal to the greater of (i) $16.88 or (ii) the quarterly
distribution attributable to a Preferred Unit if such unit had been converted
into Common Units, subject to adjustment for customary anti-dilution rights.
Each Preferred Unit shall have a stated value equal to $1,000.00 (the "Stated
Value"). Cali shall have the right to cause the conversion of any or all of the
Preferred Units into Common Units, at any time after the seven and one-half
(7-1/2) year anniversary of the date of the closing of the Mack Combination at
their Stated Value, plus accrued but unpaid distributions, divided by $34.65 per
share (the "Conversion Price"); provided, however, that Cali may only exercise
such mandatory conversion if, for twenty (20) trading days within the thirty
(30) consecutive trading days immediately preceding such conversion date, the
closing price of the Common Stock equals or exceeds $34.65, subject to
adjustment for customary anti-dilution rights. Holders of the Preferred Units
may convert the Preferred Units into Common Units at any time at the Conversion
Price. If, prior to the conversion of all Preferred Units, the number of
outstanding Common Units is increased by a unit split or other similar event,
the Conversion Price shall be proportionately reduced, or if the number of
outstanding Common Units is decreased by a combination or reclassification of
units, or other similar event, the Conversion Price shall be proportionately
increased. In addition, if, prior to the conversion of all Preferred Units,
there shall be any merger, consolidation, exchange of units, recapitalization,
reorganization, or other similar event, as a result of which Common Units of
CRLP shall be changed into the same or a different number of securities of the
same or another class or classes of units or securities of CRLP or another
entity, then the holders of Preferred Units shall thereafter have the right to
purchase and receive upon conversion of units of Preferred Units, such units
and/or securities as may be issued or payable with respect to or in exchange for
the number of Common Units immediately theretofore purchasable and receivable
upon the conversion of
 
                                       26
<PAGE>
units of Preferred Units held by such holders had such merger, consolidation,
exchange of shares, recapitalization or reorganization not taken place.
 
    Cali and CRLP shall not, without the affirmative consent of the holders of
at least sixty-six and two-thirds percent (66 2/3%) of the holders of the Series
B Preferred Units (without the need for consent of the holders of the Series A
Preferred Units) (i) subject to certain exceptions, increase or decrease (other
than by conversion) the total number of authorized shares of Series A or Series
B Preferred Units; (ii) in any manner authorize, create or issue any additional
preferred units or any class or series of capital interests, in either case (A)
ranking, either as to payment of distributions or distribution of assets, prior
to the Series A or Series B Preferred Units, or (B) which in any manner
adversely affects the holders of units of Series A or Series B Preferred Units,
or authorize, create or issue any capital interests of any class or series or
any bonds, debentures, notes or other obligations convertible into or
exchangeable for, or having optional rights to purchase, any capital interests
having any such preference or priority or so adversely affecting the holders of
Series A or Series B Preferred Units. Notwithstanding the foregoing provisions,
the affirmative consent of the holders of at least sixty-six and two-thirds
percent (66-2/3%) of the holders of the Series B Preferred Units shall not be
required for the issuance of one or more classes of capital stock or units PARI
PASSU to the Preferred Units (such Preferred Units hereinafter referred to as
"Qualifying Preferred Units"), in an aggregate amount not to exceed the greater
of (1) $200 million in stated value or (2) ten percent (10%) of Cali's total
equity market capitalization (calculated by multiplying (x) the average trading
price of Common Stock (as reported daily in THE WALL STREET JOURNAL) for the
five (5) trading days immediately preceding the date of issuance of such
Qualifying Preferred Stock, times (y) the total number of the then issued and
outstanding Common Units and shares of Common Stock, including all shares of
preferred stock and preferred units and convertible debt, which by their
respective terms are convertible into either Common Units or Common Stock; (iii)
in any manner alter or change the designations or the powers, preferences or
rights, or the qualifications, limitations or restrictions of the Series A or
Series B Preferred Units; and (iv) reclassify the Common Units or any other
units of any class or series of capital interests hereafter created junior to
the Series A or Series B Preferred Units into capitalization of any class or
series of capital interests (A) ranking, either as to payment of dividends or
distribution of assets prior to the Series A or Series B Preferred Units, or (B)
which in any manner adversely affects the holders of Series A or Series B
Preferred Units.
 
    The Warrants shall be exercisable at any time after the first anniversary of
the closing of the Mack Combination for a period of four (4) years thereafter at
a purchase price of $37.80 per unit of Common Units, subject to adjustment for
customary anti-dilution rights. The Warrants may be exercised or converted only
(a) under circumstances such that the issue of Common Units upon such exercise
or conversion is exempt from the requirements of registration under the
Securities Act of 1933, as amended (the "1933 Act") and any applicable state
securities law or (b) upon registration of such Common Units in compliance
therewith. The Warrants shall be transferable only (a) in accordance with or as
otherwise specifically permitted by the provisions of the Contribution and
Exchange Agreement and (b) under circumstances such that the transfer is exempt
from the requirements of registration under the 1933 Act and any applicable
state securities law. In the event of any change in Common Units by reason of
any dividend, recapitalization, reorganization, merger, consolidation, split-up,
combination or exchange of units, or of any similar change affecting the Common
Units, the number and kind of units underlying the Warrants and the purchase
price per unit thereof shall be appropriately adjusted consistent with such
change.
 
    The Warrants and the Units to be issued pursuant to the Mack Combination
represent the equivalent of 13,194,713 shares of Common Stock, which shares may
be purchased by Mack upon the exercise of the Warrants and the conversion and/or

the Common Units, the Preferred Units, the Warrants and the Common Units
underlying the Preferred Units and the Warrants may be transferred privately

thereunder) in blocks of not greater than 1,000,000 shares of Common Stock on
any one trading day and no more than 3,000,000 shares of Common Stock per week.
 
    Prior to the sale of any Preferred Units or Common Units by any holder
thereof, such holder shall first deliver a written notice (the "Sale Notice") to
CRLP specifying (i) the nature and class of the securities to be transferred,
(ii) the number of securities owned by such holder, (iii) the number of
securities that such holder desires to sell, (iv) the proposed cash selling
price for the securities to be sold and (v) all other material terms and

investment bank (as that term is generally defined), including, without
limitation, equity swaps and derivative transactions, as security for debt;

securities during the applicable holding period equal or exceed fifty (50%)
percent of the total value of the securities held by the individual holder or
group of holders pledging such securities or otherwise encumbering them as of
the closing of the Mack Combination (such fifty (50%) percent determination made
at the date of the pledge or granting of the encumbrance without consideration
for any reduction in value of the securities after the borrowing is effected);
and (ii) transfers of the Units, the Warrants and their underlying shares of
Common Stock to permitted transferees, as defined in and pursuant to the
Contribution and Exchange Agreement.

REMEDIES
 
    If Mack has satisfied and performed all of the conditions to closing
required to be satisfied or performed by it and if either Cali or CRLP is not
ready, willing and able to perform its obligations under the Contribution and
Exchange Agreement on the closing of the Mack Combination, in the event of a
willful default by Cali or CRLP, then Mack shall be entitled to either (a)
terminate the Contribution and Exchange Agreement upon notice to Cali and CRLP
or (b) pursue all of its available remedies at law.
 
    If both Cali and CRLP have satisfied and performed all of the conditions to
closing required to be satisfied or performed by them and if Mack is not ready,
willing and able to perform its obligations under the Contribution and Exchange
Agreement on the closing of the Mack Combination, in the event of a willful
default by Mack, then Cali and CRLP shall be entitled to either (a) terminate
the Contribution and Exchange Agreement upon notice to Mack or (b) pursue all of
their available remedies at law.
 
RESTRICTIONS ON SALE OF THE PROPERTY
 
    The Contribution and Exchange Agreement prohibits the sale of any of the
Mack Properties in a taxable transaction prior to a specific date (the
"Restricted Period") with respect to each Property (resulting in an aggregate
average Restricted Period for all of the Mack Properties of approximately seven
and one-half years) without the written consent of William L. Mack, provided,
however, that a Property may be sold during the Restricted Period without such
consent if (i) the sale of such Property would not cause the holders of the
Units to recognize a gain attributable to the excess of the fair market value of
the Property to be sold at the time of such sale over the adjusted tax basis of
the Property at the time of such sale or (ii) the sale does result in a gain,
but CRLP reimburses the holders of the Units for all taxes resulting from the
sale and attributable to the recognition of any such built-in-gain. In addition,
CRLP may dispose of one or more of the Mack Properties during the Restricted
Period without the consent of William L. Mack in connection with (i) the sale of
substantially all of its properties or (ii) under certain circumstances, the
determination of the Board of Directors that a sale is reasonably necessary to
either satisfy a material monetary default on an unsecured debt or liability of
CRLP when it becomes due or to cure or satisfy a material monetary default on a
mortgage secured by such Property or Mack Properties.
 
    After the expiration of the Restricted Period, CRLP may dispose of a
Property at any time. If CRLP intends to sell Mack Properties, it must send an
offering notice to holders of the Units informing them of the terms upon which
it intends to make the sale, and for 30 days from receipt of such notice, the
Unit holders may elect to purchase such Property. If the holders elect to
purchase the Property, they may use the Units as consideration for the sale. If
the holders do not elect to purchase the Property within 30 days, CRLP may sell
the Property on such terms and conditions as it elects, provided that the sale
is consummated for at least 95% of the price specified in the offering notice.
 
NON-COMPETITION AGREEMENTS
 
    Upon closing the Mack Combination, William L. Mack, Earle I. Mack, David S.
Mack and Frederic H. Mack each will enter into a non-competition agreement with
Cali. Each of David S. Mack and Frederic H. Mack, pursuant to his respective
non-competition agreement, will agree not to compete with Cali within the
continental United States by engaging in, owning, investing in, managing or
controlling any venture or enterprise engaged in development, acquisition or
management activities with respect to office-service, office or flex properties
until the later to occur of (i) three (3) years from the consummation of the
Mack Combination or (ii) the date on which Mack's Significant Interest is no
longer retained. The aforementioned non-competition prohibition shall not apply
to passive investments in real estate entities where neither David S. Mack nor
Frederic H. Mack, respectively, has any active participation in the business and
such investments do not exceed (i) five (5%) percent of the outstanding stock of
any class of securities that is publicly traded or (ii) the lesser of a twenty
(20%) percent equity interest or $15,000,000 in any private venture. In
addition, certain properties are not subject to the aforementioned
non-competition prohibition, including properties excluded from the Mack
Combination, properties which may be reacquired from Cali after the Mack
Combination and industrial properties which may be converted to flex properties
if it is
 
                                       32
<PAGE>
determined that the most commercially practicable use for such property is flex.
Earle I. Mack's non-competition agreement shall be similar to David S. Mack's
except that it shall continue until the later of (i) three (3) years from the
consummation of the Mack Combination or (ii) the date which is both (A) one year
if Mack's Significant Interest is retained, or six (6) months if Mack's
Significant Interest is not retained, following the date Earle I. Mack ceases to
be a member of the Board of Directors and (B) Mack's Significant Interest is no
longer retained. William L. Mack's non-competition agreement shall be similar to
Earle I. Mack's except that (1) the non-competition prohibition shall not apply
to his participation in the Apollo Real Estate funds ("Apollo"), its successor
and related funds, any funds formed by Apollo or any funds in which the
principals of Apollo own a majority of the general partnership or similar
management or controlling interest; (2) the non-competition agreement shall
contain an additional requirement that none of Earle I. Mack, David S. Mack,
Frederic H. Mack nor William L. Mack shall be a member of the Board of Directors
in order to eliminate the non-competition prohibition; and (3) his passive
investments in privately held real estate entities shall be limited to the

Generally, each property has attractively landscaped sites, expansive common
areas (some with atriums), and on-site parking (some covered), in addition to
high quality design and construction. The Mack Properties are generally
professionally managed by on-site employees under the direction of either The
Mack Company or Patriot American Management and Leasing, which provides a high
level of service to tenants, as well as a proactive approach to building
maintenance.
 
    The Mack Properties are leased to a variety of service sector employers, as
well as a large number of professional firms and national and international
firms. Major tenants include, among others, AT&T Corp., AT&T Wireless Services,
Prentice-Hall, Inc., CMP Media, Inc., Toys 'R' Us, Inc., Electronic Data Systems
Corp., KPMG Peat Marwick, LLP, Western Union Financial Services, Inc., Union
Pacific Railroad Company and American Express Travel Related Services Co., Inc.
 
    Leases are typically structured with terms ranging from one to ten years,
however, approximately 2.6 million rentable square feet of the portfolio (29.4
percent of the aggregate net rentable area of the portfolio) are leased under 16
separate long-term leases which expire in 2007 or thereafter. Generally all
leases provide for contractual rent increases each five (5) year period. A
typical gross lease requires (i) payment of base rent, (ii) payment of the
tenant's proportionate share of real estate taxes, utilities and common area and
other operating expense escalations over a base year, and (iii) payment of
overtime HVAC and electrical use. Under these leases, the landlord is typically
responsible for certain structural repairs. Various of the properties are leased
to a single tenant or one or more major tenants on a triple net basis. Under
these Leases, the respective tenants(s) are responsible for paying all or a
proportionate share of all real estate taxes, utilities and operating expenses;
under some leases, the tenant directly contracts and pays for such costs.
Additionally, some of the leases provide renewal options or provisions of
varying durations which extend the original lease terms, typically at either
market rents or negotiated rental rates set forth in the leases.

LEGAL PROCEEDINGS
 
    Neither Mack nor any of the Mack Properties is subject to any material
litigation nor, to Cali's knowledge, is any material litigation threatened
against any of them, other than routine litigation arising in the ordinary
course of business, which is expected to be covered by liability insurance.
 
                              ASSUMED INDEBTEDNESS
 
    As of the consummation of the Mack Combination, it is assumed that Mack will
have an aggregate of approximately $299.7 million of indebtedness encumbering
fifteen of the Mack Properties to be acquired in connection with the Mack
Combination, which debt will be assumed by Cali. Such debt shall mature at
various dates between March 1998 and January 2009. Such debt is comprised of an
aggregate of approximately $162.3 million of fixed rate debt bearing interest at
a weighted average rate of 7.86 percent per annum, and an aggregate of
approximately $137.4 million in variable rate debt bearing interest at a
weighted average floating rate of the London Interbank Offered Rate (LIBOR) plus
72 basis points. LIBOR at September 30, 1997 was 5.66 percent.
 
                         SELECTED FINANCIAL INFORMATION
 
    The following tables set forth certain financial data on a consolidated
historical basis for Cali, on a combined historical basis for Mack and on a pro
forma basis for Cali to effect the transactions described below. The financial
data should be read in conjunction with Cali's financial statements and the
notes thereto incorporated by reference in this Proxy Statement and Mack's
financial statements and the notes thereto included elsewhere in this Proxy
Statement. The consolidated historical financial data of Cali as of December 31,
1996, 1995, 1994, 1993 and 1992 and for the periods ended December 31, 1996,
1995, 1994, 1993, 1992 and August 30, 1994 have been derived from audited
financial statements. The combined historical financial data of Mack as of
December 31, 1996 and 1995 and for the years ended December 31, 1996, 1995 and
1994 have been derived from audited financial statements. The financial data of
Cali and Mack as of and for the nine months ended September 30, 1997 and 1996
have been derived from unaudited financial statements, which, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments necessary for a fair statement of the results for the unaudited
interim periods. The financial data of Mack as of December 31, 1994, 1993 and
1992 and for the years ended December 31, 1993 and 1992 have been derived from
unaudited financial statements.
 
    The unaudited pro forma operating data for the nine months ended September
30, 1997 and for the year ended December 31, 1996, is presented as if the
completion of the Mack Combination, the 1997 Offering, certain other property
acquisitions completed by Cali subsequent to January 1, 1996, public offerings
of Common Stock in 1996 and certain other events all occurred as of January 1,
1996. The unaudited pro forma balance sheet as of September 30, 1997 is
presented as if the completion of the 1997 Offering and the Mack Combination
occurred as of September 30, 1997.
 
    The pro forma information is based upon certain assumptions that are
included in the notes to the pro forma financial statements included elsewhere
in this Proxy Statement. The pro forma information is unaudited and is not
necessarily indicative of what the financial position and results of operations
of Cali would have been as of and for the periods indicated, nor does it purport
to represent the future financial position and results of operations for future
periods.

- ------------------------------
(1) Cali considers Funds from Operations (after adjustment for straight-lining
    of rents) one measure of REIT performance. Funds from Operations is defined
    as net income (loss) before minority interest of unitholders computed in
    accordance with Generally Accepted Accounting Principles ("GAAP"), excluding
    gains (or losses) from debt restructuring and sales of property, plus real
    estate-related depreciation and amortization. Funds from Operations should
    not be considered as an alternative for net income as an indication of
    Cali's performance or to cash flows as a measure of liquidity. Funds from
    Operations presented herein is not necessarily comparable to Funds from
    Operations presented by other real estate companies due to the fact that not
    all real estate companies use the same definition. However, Cali's Funds
    from Operations is comparable to the Funds from Operations of real estate
    companies that use the current definition of the National Association of
    Real Estate Investment Trusts, after the adjustment for straight-lining of
    rents.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                    FOR MACK
 
    The following should be read in conjunction with "Mack Selected Combined
Financial Data", and the combined financial statements of Mack and the notes
thereto, appearing elsewhere in this Proxy Statement.
 
RESULTS OF OPERATIONS
 
    The Mack Properties consist of 54 office properties comprising a total of
approximately 9.2 million net rentable square feet which are held and managed in
two portfolios. The Mack Company's office property portfolio consists of 32
office properties approximating 5.8 million net rentable square feet located in
major U.S. markets, with a concentration in Northern New Jersey and Phoenix,
Arizona. The Patriot American Office Group's office property portfolio consists
of 22 properties, 21 of which were acquired in 1992 from the Resolution Trust
Corporation ("RTC"), approximating 3.4 million square feet located principally
in the Sunbelt Region of the U.S. From 1994 through September 30, 1997, the Mack
Properties experienced significant leasing activity in both portfolios. As a
result, the combined portfolio achieved a weighted average occupancy rate of
96.1 percent as of September 30, 1997, as compared to 93.6 percent, 92.8 percent
and 89.0 percent as of December 31, 1996, 1995 and 1994, respectively.
 
NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
  1996
 
    Total revenues for the nine months ended September 30, 1997 increased $6.0
million, or 5.5 percent, over the same period in 1996. Base rents increased $2.6
million, or 2.8 percent, as a result of occupancy changes during the period and
lease rollovers at higher rental rates. Escalations and recoveries increased
$0.1 million, or 0.4 percent, as a result of increased operating costs,
partially offset by lower expense recoveries for leases that commenced in 1996
and 1997. Other income increased $3.2 million, or 112.4 percent, due primarily
to an increase in lease cancellation income. The vacated space associated with
the lease cancellations has been fully re-leased. Interest income increased $0.1
million, or 43.2 percent, primarily due to an increase in short-term investments
during the period ended September 30, 1997.
 
    Total expenses for the nine months ended September 30, 1997 increased $5.1
million, or 4.8 percent, over the same period in 1996. Real estate taxes
increased $0.6 million, or 4.9 percent, primarily due to increases in assessed
valuations and tax rates. Additionally, utilities increased $0.2 million, or 1.9
percent, and operating services increased $0.4 million, or 2.6 percent, due
primarily to changes in occupancy. General and administrative expenses increased
$3.2 million, or 58.8 percent, primarily due to $3.8 million of expenses
incurred by Mack in connection with the Mack Combination during the nine months
ended September 30, 1997, partially offset by a reduction in payroll and related
costs. Depreciation and amortization increased $0.7 million, or 3.4 percent,
primarily due to the effect of 1996 and 1997 building, tenant improvement and
leasing cost additions, partially offset by the 1996 write-off of unamortized
tenant improvements and leasing costs associated with the 1996 lease
cancellations.
 
    Income before extraordinary gain increased $0.9 million, or 25.9 percent, to
$4.4 million for the nine months ended September 30, 1997, from $3.5 million in
1996, primarily due to the factors discussed above.
 
    An extraordinary gain of $14.1 million contributed to net income of $17.6
million for the first nine months ended September 30, 1996 as compared to net
income of $4.4 million for the same period in 1997. The extraordinary gain in
1996 resulted from the early extinguishment of a $13.6 million second mortgage,
plus accrued and unpaid interest, on the One Mack Centre property located in
Tampa, Florida, for a payment of $1.5 million.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    Total revenues increased $7.0 million, or 5.0 percent, for 1996 as compared
to 1995. Base rents increased $3.6 million, or 2.9 percent, primarily due to
changes in occupancy, and lease rollovers at increased rental rates. Escalations
and recoveries increased $2.1 million, or 14.3 percent, primarily due to
increased operating costs. Other income increased $1.0 million, or 46.4 percent
primarily due to an increase in lease cancellation income. Interest income
increased $0.3 million, or 145.0 percent, primarily due to an increase in
interest earned on short-term investments of cash balances.
 
                                       47
<PAGE>
    Total expenses for 1996 increased $2.5 million, or 1.8 percent, as compared
to 1995. Real estate taxes increased $1.0 million, or 7.1 percent, primarily due
to increases in tax rates and assessed valuations. Utilities expense increased
$0.7 million, or 5.6 percent, primarily due to occupancy changes. Operating
services increased $1.2 million, or 6.8 percent, as a result of occupancy
changes, and an increase in costs associated with the harsh winter of 1996
experienced in the northeastern states. General and administrative expenses
decreased $0.4 million, or 5.3 percent, primarily due to reduced payroll and
related costs. Depreciation and amortization expense increased $1.2 million, or
4.7 percent, primarily due to the write-off of unamortized tenant improvement
and leasing costs associated with the 1996 lease cancellations and the effect of
1995 and 1996 building, tenant improvement and leasing cost additions. Interest
expense decreased $1.3 million, or 2.1 percent, due to decreases in the
effective interest rates on variable rate debt and the restructuring or
refinancing of certain loans to lower interest rates, partially offset by higher
variable rate debt balances.
 
    Income before extraordinary item increased $4.4 million, or 267.8 percent,
to $6.1 million for the year ended December 31, 1996 compared to $1.7 million
for the year ended December 31, 1995 due to the factors discussed above.
 
    A net extraordinary loss of $17.6 million contributed to a net loss of $11.5
million in 1996 as compared to net income of $1.7 million for 1995. The
extraordinary loss resulted from a $31.7 million loss realized on the early
extinguishment of the RTC debt at an amount greater than its carrying value,
partially offset by a $14.1 million gain on the early extinguishment of a $13.6
million second mortgage, plus accrued and unpaid interest, on the One Mack
Centre property located in Tampa, Florida, for a payment of $1.5 million.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
    Total revenues for 1995 increased $8.3 million, or 6.3 percent, as compared
to 1994. Base rents increased $8.5 million, or 7.5 percent, primarily due to
increased occupancy at higher rental rates and full year occupancy for leases
that commenced in 1994, including a 20-year lease on 475,000 net rentable square
feet at the Mack Saddle River property. Escalation and recoveries decreased $0.2
million, or 1.4 percent, primarily due to occupancy changes.
 
    Total expenses for 1995 increased $4.4 million, or 3.3 percent, as compared
to 1994. Operating services increased $0.2 million, or 1.0 percent, primarily
due to occupancy changes. General and administrative expenses decreased $0.1
million, or 1.7 percent, primarily due to reduced payroll and related costs.
Depreciation and amortization increased $1.5 million, or 6.0 percent, primarily
due to the effect of 1994 and 1995 building, tenant improvement and leasing cost
additions. Interest expense increased $2.8 million, or 5.1 percent, primarily
due to interest associated with the Mack Saddle River property which was
capitalized in 1994, higher variable rate debt balances and increases in the
effective interest rates on variable rate debt.
 
    Net income increased $3.9 million, or 175.1 percent, to $1.7 million for
1995 from a net loss of $2.2 million for 1994 due to the factors discussed
above.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Historically, rental revenue has been the principal source of funds to pay
operating expenses, debt service and capital expenditures, excluding
non-recurring capital expenditures. To the extent that Mack's cash flow from
operating activities is insufficient to finance its capital expenditures, Mack
has historically financed such activities through loans and partner capital
contributions and financing. Mack expects to meet its short-term liquidity
requirements generally through its working capital and net cash provided by
operating activities.
 
    Mack does not generally reserve funds to retire mortgages and loans payable
upon maturity. Instead, Mack seeks to refinance such debt at maturity. Mack
anticipates that its available cash and cash equivalents and cash flows from
operating activities, together with cash available from borrowings and partner
contributions, will be adequate to meet the Mack's capital and liquidity needs
both in the short and long-term.
 
    Mack's net cash provided by operating activities increased $8.4 million to
$35.1 million for the nine months ended September 30, 1997 from $26.7 million in
the same period in 1996, principally as a result of
 
                                       48
<PAGE>
increased net income before extraordinary item of $0.9 million resulting from
higher rental revenues and the lease cancellation income, partially offset by
increased operating costs and general and administrative expenses discussed
above, an increase in accounts payable and accrued expenses, and a slower rate
of decrease in rents received in advance and security deposits. Additionally,
unbilled rents receivable decreased by $3.6 million for the first nine months of
1997 due to lease terminations and modifications of certain leases during the
period, and scheduled contractual rent increases, compared to an increase in the
receivable of $0.5 million for the nine months ended September 30, 1996. Mack's
net cash from operating activities increased to $39.9 million in 1996 from $27.7
million for the year ended December 31, 1995 due to an increase in income before
extraordinary item of $4.4 million, scheduled contractual rent increases
resulting in a slower rate of increase of unbilled rents receivable, a decrease
in amounts due from affiliate and increases in accounts payable and accrued
expenses. These cash flow increases were partially offset by slower rates of
increases in accrued interest payable and rents received in advance and security
deposits, and increases in deferred charges and other assets. Mack's net cash
provided by operating activities increased to $27.7 million for the year ended
December 31, 1995 from $22.3 million in 1994 primarily as a result of the
increase in net income in 1995 over a net loss in 1994, slower rates of
increases in deferred charges and other assets and amounts due from affiliate,
and increases in accrued interest payable and rents received in advance and
security deposits. These increases were partially offset by payments of accounts
payable and accrued expenses.
 
    Mack's cash flows used in investing activities, which relate primarily to
tenant improvements and building additions, increased from $3.2 million for the
nine months ended September 30, 1996 to $21.7 million for the same period in
1997, primarily as a result of an increase in additions to rental property of
$10.8 million and increased funding of restricted cash in 1997 compared to the
release of the reserve in 1996. Net cash used in investing activities decreased
to $11.5 million for the year ended December 31, 1996 from $30.6 million in 1995
primarily due to lower additions to rental property and the release of
restricted cash in 1996 compared to funding of such reserves in 1995. Net cash
used in investing activities decreased to $30.6 million in 1995 from $49.3
million in 1994 due to a reduction in additions to rental property in 1995,
partially offset by increased funding of restricted cash. In 1994, Mack added
130,000 square feet of additional net rentable office space and retrofitted the
existing building at the Mack Saddle River property in connection with the new
twenty year lease discussed above.
 
    Mack's cash flows used in financing activities decreased by $4.2 million to
$17.8 million for the nine months ended September 30, 1997 compared to $22.0
million in the same period in 1996 primarily due to a reduction in net
repayments of mortgages and other notes payable, lower payments of financing
costs, and lower net distributions to partners. Mack's cash flows used in
financing activities increased by $23.6 million for the year ended December 31,
1996 as compared to 1995, as a result of higher net debt repayments of $8.8
million in 1996 compared to $6.1 million in 1995, increased payments of
financing costs, and higher net distributions to partners in 1996 of $11.5
million as compared to net partner capital contributions of $6.5 million in
1995. The increase in net debt repayments and financing costs in 1996 is
primarily due to the refinancing of the RTC debt and other mortgage refinancings
and restructurings during 1996. Net cash flows from financing activities
decreased by $24.9 million in 1995 from 1994 primarily as a result of net debt
repayments of $6.1 million in 1995 as compared to net borrowings of $5.5 million
in 1994, along with reduced net cash contributions from partners of $6.5 million
in 1995 compared to $20.1 million in 1994. In 1994, the partner loans and
capital contributions were primarily used to fund the construction and retrofit
of the Mack Saddle River property discussed above.
 
    Where performed, the Phase I assessments of the Mack Properties have not
revealed any environmental liability that Mack believes would have a material
adverse effect on Mack's business, assets or results of operations taken as a
whole, nor is Mack aware of any such material environmental liability.
 
INFLATION
 
    Mack's leases with the majority of its tenants provide for recoveries and
escalation charges based upon the tenant's proportionate share of and/or
increases in real estate taxes and certain operating costs which reduce Mack's
exposure to increases in operating costs resulting from inflation.

during 1996 to executive officers who did not have employment agreements with
Cali such determinations were made by the Compensation Committee of the Board

consisted solely of base salary, grants of stock options under Cali's Employee
Stock Option Plan that vest over time, and bonuses paid to Thomas A. Rizk, John

Lefkowitz.
 
    EXECUTIVE COMPENSATION PHILOSOPHY.  The Compensation Committee will annually
consider the appropriate combination of cash and option-based compensation and
weigh the competitiveness of Cali's overall compensation arrangements in
relation to comparable real estate investment trusts. From time to time the
Compensation Committee may retain compensation and other management consultants
to assist with, among other things, structuring Cali's various compensation
programs and determining appropriate levels of salary, bonus and other
compensation awards payable to Cali's executive officers and key employees, as
well as to guide Cali in the development of near-term and long-term individual
performance objectives necessary to achieve long-term profitability.
 
    The Compensation Committee believes that a fundamental goal of Cali's
executive compensation program should be to provide incentives to create value
for Cali's shareholders.
 
    BASE SALARIES.  The base compensation for Cali's executive officers in 1996
was established in a manner consistent with the provisions of existing
employment agreements between Cali and Thomas A. Rizk, John R. Cali and Brant
Cali, and through negotiations between Cali and the executive officers who did
not have employment agreements with Cali. The base compensation levels were set
to compensate the
 
                                       59
<PAGE>
executive officers for the functions they will perform as well as to be
consideration for certain non-competition provisions in the agreements. While no
specific formula was used to determine base compensation levels for Cali's
executive officers, Cali believes that the base salaries are generally in line
with those of other publicly held real estate investment trusts Cali has
reviewed, some of which entities are included in the NAREIT Equity REIT Index.
Base salaries will be reviewed annually and may be increased by the Compensation
Committee 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 Cali competes for executive talent. The weight
given such factors by the Compensation Committee may vary from individual to
individual.
 
    ANNUAL BONUS COMPENSATION.  Cali'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 provided financial
rewards for the achievement of substantive company and personal objectives.
Actual awards paid are based primarily on Cali's actual performance. During 1996
cash bonuses were awarded as follows: $750,000 to Thomas A. Rizk, $125,000 to
each of John R. Cali and Brant Cali, $25,000 to James Nugent, $60,000 to each of
Roger W. Thomas and Barry Lefkowitz and $35,000 to Albert Spring.
 
    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 Cali, (ii) his or her performance and
responsibilities, (iii) the extent to which he or she already holds an equity
stake in companies in the compensation peer group and (iv) individual
contribution to the success of Cali'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
Compensation Committee's evaluation of the past as well as the future
anticipated performances and responsibilities of the individual in question.
During 1996, 125,000 options at an exercise price of $26.25 per share were
granted to each of Thomas A. Rizk, Brant Cali and John R. Cali, 35,000 options
at $21.50 per share were granted to each of Barry Lefkowitz, Roger Thomas and
James Nugent, and 40,000 options at $21.50 per share were granted to Albert
Spring.
 
    Cali's Employee Stock Option Plan related closely to traditional forms of
equity-oriented compensation in the commercial real estate industry. The purpose
of the option grants are to aid Cali in attracting and retaining quality
employees, all advancing the interest of Cali's shareholders, by offering
employees an incentive to maximize their efforts to promote Cali's economic
performance. In addition, to assist Cali in retaining employees and encouraging
them to seek long-term appreciation in the value of Cali's stock, options
generally are not exercisable immediately upon grant, but instead vest over a
period of years. Accordingly, an employee must generally remain with Cali for a
period of years to enjoy the full economic benefit of an option. See, "Proposal
No. 3--Amendment to the Employee Stock Option Plan" for a general description of
the Plan.
 
    401(K) SAVINGS PLAN.  Cali also maintains a tax-qualified 401(k) savings
plan for its eligible employees known as the "Cali Realty Corporation 401(k)
Savings and Retirement Plan" ("401(k) Plan"). Employees who have attained age 21
and completed one year of service with Cali 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. Cali may make discretionary matching 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 become vested in any matching
contributions made on their behalf after two years of service with Cali at a
rate of 20% per year becoming 100% vested after a total of six years of service
with Cali. 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 Cali.

    CHIEF EXECUTIVE OFFICER COMPENSATION.  Thomas A. Rizk, the Chief Executive
Officer of Cali since January 1, 1996, received a base salary during 1996 of
$300,000 pursuant to the employment agreement entered into with him at the time
of Cali's initial public offering. Mr. Rizk also received an option to purchase
125,000 shares of Common Stock at an exercise price of $26.25 per share under
the Employee Stock Option Plan during 1996 and fees in the amount of $14,250 for
his service as a Director of Cali. In 1996, Mr. Rizk was also paid a cash bonus
of $750,000. The Compensation Committee recognizes Mr. Rizk's contributions to
Cali's operations and attempts to ensure that the Chief Executive Officer's
compensation is commensurate with the compensation of chief executive officers
of competitive corporations. The Board of Directors deemed such bonus, option
grants and Mr. Rizk's total compensation appropriate in light of Mr. Rizk's
substantial contribution to Cali's growth and success in 1996.
 
    In January 1997, Cali entered into amended employment agreements with three
of its existing executive officers and new employment agreements with four of
its existing executive officers. In addition, on January 31, 1997, in connection
with the RM Transaction, Cali entered into employment agreements with two of the
former principals of Robert Martin. See "Certain Relationships and Related
Transactions -- New Employment Contracts; Termination of Employment" for a
general description of the terms of such agreements.

PERFORMANCE GRAPH
 
    Trading of Cali's Common Stock commenced on August 25, 1994, on a when
issued basis. The following graph compares total shareholder returns from August
31, 1994 through December 31, 1996 to the Standard & Poors 500 Stock Index ("S&P
500") and to the National Association of Real Estate Investment Trusts, Inc.'s
Equity REIT (excluding Health Care REITs) Total Return Index ("NAREIT"). The
graph assumed that the value of the investment in Cali's Common Stock and in the
S&P 500 and NAREIT indices was $100 at August 31, 1994 and that all dividends
were reinvested. The Common Stock's price on August 31, 1994 (on which the graph
is based) and the initial public offering price of the Common Stock was $17.25.
 
    The stockholder return shown on the following graph is not necessarily
indicative of future performance. Cali does not believe that the graph is
particularly meaningful in that it covers a short period of time.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Certain directors and executive officers of Cali (or members of their
immediate families) and persons who will hold more than 5 percent of the
outstanding shares of Common Stock (or interests redeemable therefor) have
direct interests in transactions which have been or will be consummated by Cali,
including the transfer of certain Mack Properties and entities owning Mack
Properties to Cali.
 
REGISTRATION RIGHTS
 
    Pursuant to the Contribution and Exchange Agreement, as soon as practicable
following the one year anniversary of the closing of the Mack Combination, Cali
shall file or cause to be filed with the Securities and Exchange Commission an
effective "evergreen" Form S-3 shelf registration statement with respect to the
shares of Cali's Common Stock underlying the Units and the Common Units received
upon exercise of the Warrants. Cali shall bear all expenses incident to such
registration requirements, excluding any underwriting discounts, commissions or
transfer taxes, if any, relating to such shares of Common Stock. In addition,
Cali has agreed to provide to Mack unlimited demand registration rights for
underwritten offerings.
 
NON-COMPETITION AGREEMENTS
 
    On or prior to the closing of the Mack Combination, David S. and Frederic H.
Mack shall each enter into a non-competition agreement with Cali pursuant to
which, among other things, each of them will agree not to compete with Cali
within the continental United States by to engaging in, owning, investing in,
managing or controlling any venture or enterprise engaged in development,
acquisition or management activities with respect to office-service, office or
flex properties until the later to occur of (i) three (3) years from the
consummation of the Mack Combination or (ii) the date on which Mack's
Significant Interest is no longer maintained. The aforementioned non-competition
prohibition shall not apply to passive investments in real estate entities where
neither David S. Mack nor Frederic H. Mack, respectively, has any active
participation in the business and such investments do not exceed (i) five (5%)
percent of the outstanding stock of any class of securities that is publicly
traded or (ii) the lesser of a twenty (20%) percent equity interest or
$15,000,000 in any private venture. In addition, certain properties are not
subject to the aforementioned non-competition prohibition, including properties
excluded from the Mack Combination, properties which may be reacquired from Cali
after the Mack Combination and industrial properties which may be converted to
flex properties if it is determined that the most commercially practicable use
for such property is flex. Upon the consummation of the Mack Combination, Earle
I. Mack shall enter into a non-competition agreement substantially similar to
David S. Mack's. However, as a member of the Board of Directors, Earle I. Mack
shall be further subject to a one year non-competition period if Mack's
Significant Interest is retained, or six (6) month non-competition period if
Mack's Significant Interest is not retained, following the termination of his
service as a member of the Board of Directors.
 
    On or prior to the closing of the Mack Combination, William L. Mack shall
enter into a non-competition agreement substantially similar to the
non-competition agreement entered into by Earle I Mack, provided, however, that
William L. Mack's non-competition agreement shall contain, among other things,
additional provisions which will (1) allow him to continue his participation in
the Apollo Real Estate funds ("Apollo"), its successor and related funds, any
other funds formed by Apollo and any other funds in which the principals of the
Apollo own a majority of the general partnership or similar management or
controlling interest, (2) limit his passive investments in privately held real
estate entities to the lesser of a fifteen (15%) percent equity interest or
$15,000,000 and (3) extend the term of his non-competition period until the date
on which (a) neither Earle I., David S. nor Frederic H. Mack serves as a member
of the Board of Directors and (b) Mack's Significant Interest is no longer
maintained.

NEW EMPLOYMENT CONTRACTS; TERMINATION OF EMPLOYMENT
 
    MITCHELL E. HERSH EMPLOYMENT AGREEMENT.  Upon the consummation of the Mack
Combination, Mitchell E. Hersh shall enter into an employment agreement with
Cali (the "Hersh Employment Agreement") similar to the employment agreement to
be entered into between Cali and Thomas A. Rizk upon the consummation of the
Mack Combination. Upon consummation of the Mack Combination, Mitchell E. Hersh
and two executive officers of The Mack Company, who are employed at Patriot
American, collectively will receive warrants exercisable for an aggregate of up
to 515,000 shares of Common Stock at an exercise price equal to the price of the
Common Stock of Cali, as reported in THE WALL STREET JOURNAL, on the date of the
closing of the Mack Combination, which warrants shall possess terms
substantially similar to those of options under Cali's Employee Stock Option
Plan.
 
    EMPLOYMENT AGREEMENTS WITH CURRENT SENIOR EXECUTIVES.  Upon consummation of
the Mack Combination, Cali intends to enter into new employment agreements with
Thomas A. Rizk, John R. Cali and Brant Cali containing non-competition
provisions and amended and restated employment agreements with Roger W. Thomas,
Barry Lefkowitz, Albert Spring, James Nugent, Brad Berger and Timothy Jones.
Pursuant to these agreements, the senior executives will receive the following
annual base salaries: Thomas A. Rizk, $1,050,000; John R. Cali, $325,000; Brant
Cali, $325,000; Roger W. Thomas, $300,000; Barry Lefkowitz, $300,000; Albert
Spring, $175,000; James Nugent, $175,000; Brad Berger, $325,000; and Timothy
Jones, $325,000. In addition, each senior executive will receive options from a
pool of 1,135,000 options which will be made available and allocated among the
aforementioned senior executives.
 
    ANNUAL SALARY OF JOHN J. CALI.  Upon consummation of the Mack Combination,
John J. Cali will receive an annual base salary of $150,000.
 
BENEFITS OF THE PROPOSALS TO CERTAIN EXECUTIVE OFFICERS
 
    CONSIDERATIONS AND RECOMMENDATIONS OF THE COMPENSATION COMMITTEE AND
RATIFICATION BY BOARD OF DIRECTORS.  In connection with the Mack Combination,
the Option and Executive Compensation Committee (the "Compensation Committee")
of the Board of Directors, consisting (since May 1997) of Messrs. Brendan T.
Byrne, Irvin D. Reid and Alan G. Philibosian, recommended that the full Board of
Directors approve payment of the compensation set forth below to certain senior
executives of Cali, upon the consummation of the Mack Combination. The
Compensation Committee carefully considered the impact of the Mack Combination
both on Cali and its existing senior executives in order to determine what
actions would constitute fair and even handed treatment of these senior
executives who were essential to bringing about the Mack Combination.
 
    Included in the many factors considered by the Compensation Committee were
the impending changes in the ownership of Cali, the structure of the Board and
the job titles and functions of Cali's existing senior executives directly
attributable to the Mack Combination. The Committee also considered the
employment agreements that were in place for certain senior executives and the
effects of the Mack Combination on these agreements (details concerning these
agreements are set forth below). In addition, the Committee considered the hard
work and dedication that will be required on the part of the senior executives
to effectuate the Mack Combination. Finally, it was noted that the consummation
of the Mack Combination represents the earlier than anticipated attainment of
Cali's long range plans and goals and results in placement of Cali in a select
group of REITs who excel in their marketplace.
 
    Based upon the overall impact of the Mack Combination, including the factors
cited above, the Compensation Committee, after consultation with Cali's outside
counsel, unanimously took the actions described below and made a recommendation
to the Board of Directors to ratify such actions. Upon further consideration of
the proposals recommended by the Compensation Committee, the full Board of
Directors (with Messrs. Thomas A. Rizk, Brant Cali, John J. Cali and Brad W.
Berger abstaining) then unanimously ratified the recommendations of the
Compensation Committee.
 
                                       64
<PAGE>
    EMPLOYMENT AGREEMENTS, CHANGE IN CONTROL.  Each of Messrs. Rizk, John R.
Cali, Brant Cali, Thomas, Lefkowitz, Nugent and Spring entered into employment
agreements with Cali, effective January 21, 1997, pursuant to which each senior
executive was granted restricted shares of Common Stock ("Restricted Stock")
and, with the exception of Messrs. John R. Cali and Brant Cali, a non-recourse
loan to acquire Common Stock ("Stock Acquisition Loan"). Each senior executive's
Restricted Stock would generally vest and his Stock Acquisition Loan be forgiven
over his initial five year employment period with partial tax gross up payments
to be made at the time of vesting or forgiveness.
 
    Under these senior executives' employment agreements, upon a change in
control of Cali (as defined in each employment agreement), each of the
aforementioned senior executives would be entitled to acceleration of (i) the
vesting of his Restricted Stock, including tax gross up payments associated
therewith, (ii) the forgiveness of his Stock Acquisition Loan, including tax
gross up payments associated therewith and (iii) the vesting of his outstanding
options. The Board of Directors of Cali, after considering the recommendation of
the Compensation Committee and the factors considered by the Compensation
Committee, has determined that a change in control would occur upon the
consummation of the Mack Combination, thereby resulting in the acceleration of
the vesting of the Restricted Stock and options, and the forgiveness of the
Stock Acquisition Loan, including the payment of all related tax gross up
amounts. The value of accelerated vesting in Restricted Stock, Stock Acquisition
Loan forgiveness, options and the tax gross-up payments determined to be payable
for each executive upon consummation of the Mack Combination, assuming a $38.50
stock price, is as follows: Mr. Rizk, Restricted Stock $2,139,000, Stock
Acquisition Loan forgiveness $3,000,000, options $918,750, tax gross-up
$2,056,000; for each of Brant Cali and John R. Cali, Restricted Stock
$2,139,000, options $918,750, tax gross-up $856,000; for each of Messrs. Thomas
and Lefkowitz, Restricted Stock $357,000, Stock Acquisition Loan forgiveness
$500,000, options $357,000, tax gross-up $343,000; Mr. Nugent, Restricted Stock
$285,000, Stock Acquisition Loan forgiveness $400,000, options $357,000, tax
gross-up $274,000; and Mr. Spring, Restricted Stock $249,000, Stock Acquisition
Loan forgiveness $350,000, options $408,000, tax gross-up $240,000.
 
    EMPLOYMENT AGREEMENTS, TERMINATION FOR GOOD REASON.  Under each of Messrs.
Rizk's, Brant Cali's and John R. Cali's employment agreements with Cali, each
executive is entitled under certain circumstances to resign for "good reason"
(as defined in the employment agreements), to receive payment under the
employment agreements of the applicable amounts specified under the "Change in
Control" section outlined above as well as certain severance payments, (totaling
$9,060,000 for Mr. Rizk and $5,660,000 for each of Brant Cali and John R. Cali).
Furthermore, upon a resignation for "good reason," each such executive could
immediately compete directly with Cali. In view of the significant changes in
the overall authority, duties and responsibilities of these individuals
resulting from the Mack Combination, the Compensation Committee determined and
the Board of Directors of Cali concurred that consummation of the Mack
Combination would entitle 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
Compensation Committee and the Board of Directors have concluded that the
continued employment of and lack of competition by these senior executives is
essential to the continued success of Cali's business and in the best interests
of Cali and its stockholders. Therefore, the Board, in its discretion, has
authorized Cali to enter into new employment agreements with these senior
executives, effective upon the consummation of the Mack Combination, pursuant to
which among other things, the senior executives would be paid the amounts
referenced above in cancellation of their January 21, 1997 employment agreements
and for the re-affirmation of their agreements not to compete directly with
Cali. Each of these senior executives has agreed to enter into a new employment
agreement with Cali pursuant to which each of the senior executives will waive
any right he may have to sever employment and compete with Cali as a result of
the Mack Combination.
 
    WARRANTS.  Messrs. Jones and Berger were each granted 170,000 warrants in
connection with their employment agreements with Cali effective January 31,
1997. Pursuant to the terms of each of Messrs. Jones' and Berger's warrants, the
vesting of these warrants will be accelerated upon a change in
 
                                       65
<PAGE>
control which, consistent with the Board of Directors' determination, would
occur upon consummation of the Mack Combination. Assuming a $38.50 stock price
upon the consummation of the Mack Combination, the value of each executive's
accelerated warrants is $935,000, and each executive will have accelerated
vesting in options granted to him with a value of $99,000.
 
    ADDITIONAL GROSS-UP PAYMENTS.  In recognition of the performance and valued
service of Messrs. Thomas, Lefkowitz, Nugent and Spring, the Board of Directors
authorized the payment to each of these senior executives, upon the consummation
of the Mack Combination, of an additional discretionary tax gross-up payment in
order to enable these executives to meet their respective full tax obligations
related to the accelerated vesting of their Restricted Stock and forgiveness of
their Stock Acquisition Loans. These additional discretionary tax gross up
payments will enable each of the senior executives to maintain their equity
positions which may have otherwise been liquidated to meet their respective full
tax obligations. The amounts are as follows: Messrs. Thomas and Lefkowitz
$385,000; Mr. Nugent $308,000; Mr. Spring $270,000.
 
    INCENTIVE AND MERIT BONUSES.  In connection with the Mack Combination,
Messrs. Jones, Berger, Thomas, Lefkowitz, Nugent and Spring, in recognition of
their contributions and valued service with regard to the successful
origination, structuring and completion of the Mack Combination, each will
receive a discretionary incentive and merit bonus as determined by the Board of
Directors as follows: Messrs. Jones and Berger $1,400,000 each; Mr. Thomas
$625,000; Mr. Lefkowitz $550,000; Mr. Nugent $350,000; and Mr. Spring $400,000.
 
    TAX CONSIDERATIONS.  Pursuant to Section 162(m) of the Internal Revenue Code
of 1986, as amended (the "Code") amounts paid to the Chief Executive Officer and
the next four (4) highest compensated officers in excess of $1,000,000 are not
deductible.

                       FEDERAL INCOME TAX CONSIDERATIONS
 
    The following summarizes certain federal income tax considerations that may
be relevant to a holder of Common Stock following the Mack Combination. The
summary is based on current law, is for general information only, and is not to
be considered tax advice. The tax treatment of a holder of Common Stock will
vary depending upon such holder's particular situation, and this discussion does
not purport to deal with all aspects of taxation that may be relevant to
particular stockholders in light of their personal investment or tax
circumstances, or to certain types of stockholders (including insurance
companies, financial institutions or broker-dealers, tax-exempt organizations,
foreign corporations, and persons who are not citizens or residents of the
United States, except to the extent discussed under the heading "Taxation of
Tax-Exempt Stockholders" and "Taxation of Non-U.S. Stockholders," and persons
who acquired their Common Stock pursuant to the exercise of an employee stock
option or otherwise as compensation) subject to special treatment under the
United States federal income tax laws. The summary does not address any of the
tax consequences of the Mack Combination to Mack. Additionally, the discussion
does not address any tax consequences to any holders of Common Stock arising
under the laws of any state, local or foreign jurisdiction.
 
    EACH HOLDER OF COMMON STOCK IS ADVISED TO CONSULT WITH HIS OWN TAX ADVISOR,
REGARDING THE TAX CONSEQUENCES TO HIM AND OF THE MACK COMBINATION AND OF THE
OWNERSHIP AND SALE OF COMMON STOCK IN AN ENTITY THAT HAS ELECTED TO BE TAXED AS
A REAL ESTATE INVESTMENT TRUST, INCLUDING THE FEDERAL, STATE, LOCAL FOREIGN AND
OTHER TAX CONSEQUENCES OF THE CONVEYANCE AND SUCH OWNERSHIP AND SALE, AND OF
POTENTIAL CHANGES IN APPLICABLE TAX LAWS.
 
GENERAL
 
    Cali currently has in effect an election to be taxed as a REIT under
Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the
"Code"). Cali believes that it has from its inception been organized and
operated in a manner qualifying it for taxation as a REIT under the Code. In the
opinion of Pryor, Cashman Sherman & Flynn, the structure of the Mack Combination
and the proposed method of operation of Cali (including the acquisition and
operation of the Mack Properties), following the Mack Combination will enable
Cali to continue to satisfy the requirements for qualification and taxation as a
REIT under the Code. This opinion is based on certain assumptions and certain
representations made by Cali and Mack regarding certain factual matters relating
to operational practices and Cali's intended or anticipated future manner of
operation. Pryor, Cashman, Sherman & Flynn is not aware of any facts or
circumstances that are inconsistent with these assumptions and representations.
Cali's qualification and taxation as a REIT will continue to depend upon Cali's
ability to meet, on an ongoing basis, through actual annual operating results,
distribution levels and diversity stock ownership, the various qualification
tests imposed under the Code discussed below. Pryor, Cashman, Sherman & Flynn
will not review compliance with these tests on a continuing basis, and thus no
assurance can be given that Cali will satisfy such tests on a continuing basis.
See "Failure to Qualify" below. In addition, the opinion of Pryor, Cashman,
Sherman & Flynn is not binding upon the IRS.
 
    The following is a general summary of the Code sections that govern the
federal income tax treatment of a REIT and its stockholders. These sections of
the Code are highly technical and complex, and this summary is qualified in its
entirety by the applicable Code provisions, the regulations promulgated
thereunder ("Treasury Regulations") and administrative and judicial
interpretations thereof, all of which are subject to change.
 
    If Cali qualifies for taxation as a REIT, it generally will not be subject
to federal corporate income taxes on net income that it distributes currently to
its stockholders. This treatment substantially eliminates the "double taxation"
(at the corporate and stockholder levels) that generally results from investment
in a
 
                                       67
<PAGE>
corporation. However, Cali will be subject to federal income tax in the
following circumstances. First, Cali will be taxed at regular corporate rates on
any undistributed REIT taxable income, including undistributed net capital
gains. Second, under certain circumstances, Cali may be subject to the
"alternative minimum tax" on its items of tax preference. Third, if Cali has (i)
net income from the sale or other disposition of "foreclosure property" (which
is, in general, property acquired by Cali by foreclosure or otherwise upon
default on a loan secured by the property) which is held primarily for sale to
customers in the ordinary course of business or (ii) other non-qualifying net
income from foreclosure property, it will be subject to tax at the highest
corporate rate on such income. Fourth, if Cali has net income from prohibited
transactions (which are, in general, certain sales or other dispositions of
property (other than foreclosure property) held primarily for sale to customers
in the ordinary course of business), such income will be subject to a 100% tax.
Fifth, if Cali should fail to satisfy the 75% gross income test or the 95% gross
income test (as discussed below), and has nonetheless maintained its
qualification as a REIT because certain other requirements have been met, it
will be subject to a 100% tax on the net income attributable to the greater of
the amount by which Cali fails the 75% or 95% test, multiplied by a fraction
intended to reflect Cali's profitability. Sixth, if Cali should fail to
distribute during each calendar year at least the sum of (i) 85% of its REIT
ordinary income for such year (ii) 95% of its REIT capital gain net income for
such year and (iii) any undistributed taxable income from prior years, Cali
would be subject to a 4% excise tax on the excess of such required distribution
over the amounts actually distributed. Seventh, with respect to any asset (a
"Built-In-Gain Asset") acquired by Cali from a corporation which is or has been
a C corporation (i.e., generally a corporation subject to full corporate-level
tax) in a transaction in which the basis of the Built-In-Gain Asset in the hands
of Cali is determined by reference to the basis of the asset in the hands of the
C corporation and such basis is less than the fair market value of such asset at
the time of such acquisition (with the excess of such fair market value over
such basis amount being referred to as the "Built-In-Gain"), if Cali recognizes
any Built-In-Gain on the disposition of such Built-In-Gain Asset during the
ten-year period beginning on the date on which such asset was acquired by Cali
(the "Recognition Period"), then, such Built-In-Gain will be subject to tax at
the highest regular corporate rate applicable pursuant to Treasury Regulations
that have not yet been promulgated. The results described above with respect to
the recognition of Built-In-Gain assume that Cali will make an election pursuant
to IRS Notice 88-19.
 
REQUIREMENTS FOR QUALIFICATION
 
    The Code defines a REIT as a corporation, trust or association (1) which is
managed by one or more trustees or directors; (2) the beneficial ownership of
which is evidenced by transferable shares or by transferable certificates of
beneficial interest; (3) which would be taxable as a domestic corporation but
for Sections 856 through 859 of the Code; (4) which is neither a financial
institution nor an insurance company subject to certain provisions of the Code;
(5) the beneficial ownership of which is held by 100 or more persons; (6) during
the last half of each taxable year not more than 50% in value of the outstanding
stock of which is owned, directly or indirectly. by five or fewer individuals
(as defined in the Code to include certain entities); and (7) which meets
certain other tests, described below, regarding the nature of its income and
assets. The Code provides that conditions (1) to (4), inclusive, must be met
during the entire taxable year and that condition (5) must be met during at
least 335 days of a taxable year of 12 months, or during a proportionate part of
a taxable year of less than 12 months. Cali has previously issued sufficient
shares of Common Stock in sufficient proportions to allow Cali to satisfy
requirements (5) and (6). In addition, Cali's Articles of Incorporation provide
restrictions regarding ownership and transfer of its shares that are intended to
assist Cali in continuing to satisfy the share ownership requirements described
in (5) and (6) above. Pursuant to the recently enacted Taxpayer Relief Act of
1997 (the "Act"), effective for Cali's taxable years beginning on or after
January 1, 1998, so long as Cali complies with the Treasury regulations (the
"Stock Ownership Regulations") for ascertaining the ownership of its stock, Cali
will not lose its qualification as a REIT as a result of a violation of
condition (6) if it neither knows nor upon exercising reasonable due diligence
would have known of such violation. Under prior law, Cali's failure to
 
                                       68
<PAGE>
comply with the Stock Ownership Regulations could have resulted in its
disqualification as a REIT for the taxable year of the failure. For taxable
years beginning on or after January 1, 1998, Cali would be subject to a
financial penalty of $25,000 ($50,000 for intentional violations) for any year
in which it failed to comply with the Stock Ownership Regulations. Furthermore,
if Cali could establish that its failure to comply was due to reasonable cause
and not to willful neglect, no penalty would be imposed.
 
    In addition, a corporation may not elect to become a REIT unless its taxable
year is the calendar year. From its inception, Cali's taxable year has been the
calendar year.
 
    In the case of a REIT which is a partner in a partnership, Treasury
Regulations provide that the REIT will be deemed to own its proportionate share
of the assets of the partnership and will be deemed to be entitled to the income
of the partnership attributable to such share. In addition, the character of the
assets and gross income of the partnership shall retain the same character in
the hands of the REIT for purposes of Section 856 of the Code, including the
satisfaction of the gross income and asset tests. Thus. Cali's proportionate
share of the assets, liabilities and items of income of any partnership in which
Cali is a partner including the partnership's share of such assets, liabilities
and items of income of any subsidiary partnerships) will be treated as assets,
liabilities and items of income of Cali for purposes of applying the
requirements described herein.
 
    INCOME TESTS.  In order to maintain qualification as a REIT, Cali must
satisfy annually certain gross income requirements. First, at least 75% of
Cali's gross income (excluding gross income from prohibited transactions) for
each taxable year must be derived directly or indirectly from investments
relating to real property or mortgages on real property (including "rents from
real property" and, in certain circumstances, interest) or from certain types of
temporary investments (the "75% Test"). In addition, at least 95% of Cali's
gross income (excluding gross income from prohibited transactions) for each
taxable year must be derived from such real property investments, and from
dividends, interest and gain from the sale or disposition of stock or
securities, or from any combination of the foregoing (the "95% Test", and
together with the 75% Test, the "Gross Income Tests"). Finally, for the 1997
taxable year of Cali ending on December 31, 1997, short-term gain from the sale
or other disposition of stock or securities, gain from prohibited transactions
and gain on the sale or other disposition of real property held for less than
four years (apart from involuntary conversions and sales of foreclosure
property) must represent less than 30% of its gross income (including gross
income from prohibited transactions) for each taxable year. However, the 30%
Test was repealed by the Act for taxable years beginning on or after January 1,
1998. In addition, pursuant to the Act, for taxable years beginning on or after
January 1, 1998, except to the extent otherwise provided by regulations,
"qualifying income" for purposes of the Gross Income Tests would include
payments to Cali under an interest rate swap, cap agreement, option, futures
contract, forward rate agreement or any similar financial instrument entered
into by the Cali to hedge its indebtedness, as well as any gain from the
disposition of any of the foregoing investments.
 
    Rents received by Cali will qualify as "rents from real property" in
satisfying the gross income requirements described above only if several
conditions are met. First, the amount of rent must not be based in whole or in
part on the income or profits of any person. However, an amount received or
accrued generally will not be excluded from the term "rents from real property"
solely by reason of being based on a fixed percentage or percentages of receipts
or sales. Second, the Code provides that rents received from a tenant will not
qualify as "rents from real property" in satisfying the gross income tests if
Cali, or an owner of 10% or more of Cali actually or constructively owns 10% or
more of such tenant (a "Related Party Tenant"). Effective for Cali's taxable
years beginning on or after January 1, 1998, the constructive ownership rules
for determining whether a tenant is a Related Party Tenant are modified with
respect to partners and partnerships to provide that attribution between
partners and partnerships occurs only when a partner owns, directly and/or
indirectly, a 25%-or-greater interest in the partnership. Thus, a tenant will
not be treated as a Related Party Tenant with respect to Cali if shares of Cali
are owned by a partnership and a partner that owns, directly and indirectly, a
less-than-25% interest in such partnership also owns an interest in the tenant.
A tenant will also not be a Related Party Tenant if shareholders of Cali and
owners
 
                                       69
<PAGE>
of such tenant are partners in a partnership in which neither owns, directly
and/or directly, a 25%-or-greater interest. Third, if rent attributable to
personal property, leased in connection with a lease of real property is greater
than 15 percent of the total rent received under the lease (the "15%
Limitation"), then the portion of rent attributable to such personal property
will not qualify as "rents from real property". Cali does not anticipate (i)
charging rent for any portion of' any property that is based in whole or in part
on the income or profits of any person (except by reason of being based on a
percentage of receipts or sales, which, as described above is permitted); (ii)
receiving rents in excess of a DE MINIMIS amount from Related Party Tenants; and
(iii) deriving rent attributable to personal property leased in connection with
real property in excess of the 15% Limitation. Finally, for rents received to
qualify as "rents from real property," Cali generally must not operate or manage
the property or furnish or render services to tenants, other than through an
"independent contractor" from whom Cali derives no revenue. The "independent
contractor" requirement, however, does not apply to the extent the services
provided by Cali are "usually or customarily rendered" in connection with the
rental of space for occupancy only and are not otherwise considered "rendered to
the occupant." CRLP will provide certain services with respect to the properties
that are intended to comply with the "usually or customarily rendered"
requirement. In the case of any services that are not "usual and customary"
under the foregoing rules ("Impermissible Services"), Cali generally intends to
employ independent contractors to perform such services from whom it will derive
no income.
 
    Pursuant to the Act, effective for its tax years beginning on or after
January 1, 1998, Cali may render a DE MINIMIS amount of Impermissible Services
to tenants, or in connection with the management of property, without having
otherwise qualifying rents from the property being disqualified as "rents from
real property." The receipt of income in respect of such Impermissible Services
("Impermissible Services Income") does not disqualify otherwise qualifying
income from real property as "rents from real property" so long as the
Impermissible Services Income from the property does not exceed 1% of Cali's
gross income from the property for that tax year. To qualify for this 1 percent
exception, the Impermissible Services may not be valued at less than 150 percent
of Cali's direct cost of service. The amount of any Impermissible Services
Income, however, is not treated as "rents from real property" for purposes of
the 75% and 95% Gross Income Tests and, accordingly, must be considered together
with other non-qualifying income for purposes of satisfying the Gross Income
Tests.
 
    CRLP may receive fees in consideration of the performance of management and
administrative services with respect to properties that are not owned entirely
by CRLP. Although a portion of such management and administrative fees generally
will not be "qualifying income" for purposes of the Gross Income Tests, Cali
believes that the aggregate amount of such fees (and any Impermissible Services
Income or other non-qualifying income) in any taxable year will not cause Cali
to fail the Gross Income Tests.
 
    If Cali fails to satisfy one or both of the 75% or 95% Gross Income Tests
for any taxable year, it may nevertheless qualify as a REIT for such year if it
is entitled to relief under certain provisions of the Code. These relief
provisions generally will be available if Cali's failure to meet such tests was
due to reasonable cause and not due to willful neglect, Cali attaches a schedule
of the sources of its income to its federal income tax return, and any incorrect
information on the schedules was not due to fraud with intent to evade tax. It
is not possible, however, to state whether in all circumstances Cali would be
entitled to the benefit of these relief provisions. If these relief provisions
were inapplicable, Cali would not qualify as a REIT. As discussed above in
"--General," even if these relief provisions apply, a tax would be imposed with
respect to the excess net income.
 
    Effective for taxable years beginning on or after January 1, 1998, property
that was involuntarily converted will be excluded from the "prohibited
transaction" rules.
 
    ASSET TESTS.  Cali at the close of each quarter of its taxable year must
also satisfy three tests relating to the nature of its assets. First, at least
75 percent of the value of Cali's total assets (including its allocable
 
                                       70
<PAGE>
share of real estate assets held by CRLP and partnerships in which CRLP owns an
interest and assets held by "qualified REIT subsidiaries" of Cali) must be
represented by real estate assets, stock or debt instruments held for not more
than one year purchased with the proceeds of a stock offering or long-term (at
least five years) debt offering of Cali, cash, cash items and government
securities. Second, not more than 25 percent of Cali's total assets (including
its allocable share of real estate assets held by CRLP and partnerships in which
CRLP owns an interest, and assets held by "qualified REIT subsidiaries" of Cali)
may be represented by securities other than those in the 75 percent asset class.
Third, of the investments included in the 25 percent asset class, the value of
any one issuer's securities owned by Cali may not exceed 5 percent of the value
of Cali's total assets (including its allocable share of real estate assets held
by CRLP and partnerships in which CRLP owns an interest, and assets held by
"qualified REIT subsidiaries" of Cali), and Cali may not own more than 10% of
any one issuer's outstanding voting securities.
 
    A REIT which meets the foregoing asset tests at the close of any quarter
will not lose its status as a REIT for failure to satisfy the asset tests at the
end of a later quarter solely by reason of changes in asset values. If the
failure to satisfy the asset tests results from an acquisition of securities or
other property during a quarter (including as a result of the REIT increasing
its interest in any partnership in which the REIT is a partner), the failure can
be cured by disposition of sufficient nonqualifying assets within 30 days after
the close of that quarter. Cali intends to maintain adequate records of the
value of its assets to ensure compliance with the asset tests and to take such
other actions within 30 days after the close of any quarter as may be required
to cure any noncompliance. If Cali failed to cure noncompliance with the asset
tests within such time period, Cali would cease to qualify as a REIT.
 
    ANNUAL DISTRIBUTION REQUIREMENTS  Cali, in order to qualify as a REIT, is
required to distribute dividends (other than capital gain dividends) to its
stockholders in an amount at least equal to (A) the sum of (i) 95 percent of
Cali's "REIT taxable income" (computed without regard to the dividends paid
deduction and its net capital gain) and (ii) 95 percent of Cali's net income
(after tax), if any from foreclosure property minus (B) the sum of certain items
of noncash income. In addition, if Cali disposes of any Bulit-in-Gain Asset
during the Recognition Period, Cali could be required pursuant to Treasury
regulations that have not yet been promulgated to distribute at least 95 percent
of any Built-in-Gain (after tax) recognized on the disposition of such asset.
Such distributions must be paid in the taxable year to which they relate, or in
the following taxable year if declared before Cali timely files its tax return
for such prior year and if paid on or before the first regular dividend payment
after such declaration. To the extent that Cali does not distribute all of its
net capital gain or distributes at least 95 percent, but less than 100 percent,
of its "REIT taxable income," as adjusted, it will be subject to tax on the
undistributed amount at regular ordinary and capital gains tax rates. As
discussed below, stockholders of Cali, for taxable years of Cali beginning on or
after January 1, 1998, would receive a tax credit for the corporate level taxes
paid by Cali on any undistributed capital gains. See "Taxation of Domestic
Shareholders" below. Furthermore, if Cali should fail to distribute during each
calendar year at least the sum of (i) 85 percent of its REIT ordinary income for
such year (ii) 95 percent of its REIT capital gain income for such year, and
(iii) any undistributed taxable income from prior periods, Cali would be subject
to a 4 percent excise tax (the "Excise Tax") on the excess of such required
distribution over the amounts actually distributed. As discussed more completely
under "Taxation of Domestic Stockholders," Cali may elect pursuant to the Act
for its taxable years beginning on or after January 1, 1998, to retain any long
term capital gain recognized during a taxable year ("Retained Gains") and pay a
corporate level tax on such Retained Gains. The Retained Gains are then
considered to have been distributed to holders of Common Stock. It is unclear
whether any Retained Gains would be treated as having been actually distributed
for purposes of the Excise Tax. Absent public guidance from the IRS or the
adoption of corrective statutory provisions, if Retained Gains were not treated
as being actually distributed, any Retained Gains possibly could be subject to
the Excise Tax.
 
    Cali intends to make timely distributions sufficient to satisfy the annual
distribution requirements. In this regard, the partnership agreement of CRLP
authorizes Cali as general partner to take such steps as
 
                                       71
<PAGE>
may be necessary to cause CRLP to distribute to its partners an amount
sufficient to permit Cali to meet these distribution requirements. It is
possible, however, that Cali from time to time, may not have sufficient cash or
other liquid assets to meet the 95% distribution requirement due to timing
differences between the actual receipt of income and actual payment of
deductible expenses and the inclusion of such income and deduction of such
expenses in arriving at taxable income of Cali, or if the amount of
nondeductible expenses such as principal amortization or capital expenditures
exceed the amount of noncash deductions. In the event that such timing
differences occur, in order to meet the 95% distribution requirement, Cali may
or may cause CRLP to. arrange for short-term, or possibly long-term, borrowing
to permit the payment of required dividends. If the amount of nondeductible
expenses exceeds noncash deductions, CRLP may refinance its indebtedness to
reduce principal payments and borrow funds for capital expenditures.
 
    Under certain circumstances, Cali may be able to rectify a failure to meet
the distribution requirement for a year by paying "deficiency dividends" to
stockholders in a later year that may be included in Cali's deduction for
dividends paid for the earlier year. Thus, Cali may be able to avoid being taxed
on amounts distributed as deficiency dividends; however, Cali will be required
to pay to the IRS interest based upon the amount of any deduction taken for
deficiency dividends.
 
FAILURE TO QUALIFY AS A REIT
 
    If Cali fails to qualify for taxation as a REIT in any taxable year and the
relief provisions do not apply, Cali will be subject to tax (including any
applicable alternative minimum tax) on its taxable income at regular corporate
rates. Distributions to stockholders in any year in which Cali fails to qualify
will not be deductible by Cali nor will they be required to be made. In such
event, to the extent of current and accumulated earnings and profits, all
distributions to stockholders will be taxable as ordinary income, and, subject
to certain limitations in the Code, corporate distributees may be eligible for
the dividends received deduction. Unless entitled to relief under specific
statutory provisions, Cali also will be disqualified from taxation as a REIT for
the four taxable years following the year during which qualification was lost.
It is not possible to state whether in all circumstances Cali would be entitled
to such statutory relief.
 
TAXATION OF TAXABLE DOMESTIC STOCKHOLDERS
 
    As long as Cali qualifies as a REIT, distributions made to Cali's taxable
domestic stockholders out of current or accumulated earnings and profits (and
not designated as capital gain dividends) will be taken into account by them as
ordinary income and will not be eligible for the dividends received deduction
for corporations. The appropriate characterization and taxation of actual
distributions by Cali that are designated as capital gain dividends (to the
extent they do not exceed Cali's actual net capital gain and/or adjusted net
capital gain for the taxable year) will be determined at the Cali level without
regard to the period for which the stockholder has held its stock. Although the
matter is not entirely free from doubt, it appears that, pursuant to the Act,
the portion of any such distributions designated as capital gain dividends
attributable to gain recognized after July 28, 1997 with respect to capital
assets held by Cali for more than 18 months on the date of sale will be treated
as long-term capital gain taxable as a maximum rate of 20% (or 25% to the extent
any such gain arises from the recapture of straight-line depreciation deductions
reflected in the basis of real property that has been held by Cali for more than
18 months as of the date of sale) and any remaining portion of such capital gain
dividends will be treated as long-term capital gain taxable at a maximum rate of
28%. However, corporate stockholders may be required to treat up to 20% of
certain capital gain dividends as ordinary income. Distributions in excess of
current and accumulated earnings and profits will not be taxable to a
stockholder to the extent that they do not exceed the adjusted basis of the
stockholder's shares of Common Stock, but rather will reduce the adjusted basis
of such shares. Assuming a stockholder holds his shares of Common Stock as a
capital asset, any such distributions in excess of a stockholder's adjusted
basis in his shares of Common Stock will be included in income as long-term
capital gain taxable at a maximum rate of 20% if the gain is recognized after
July 28, 1997 and the
 
                                       72
<PAGE>
shares have been held for more than 18 months at the time of sale, long-term
capital gain taxable at a maximum rate of 28 percent if the shares have been
held for more than one year but not more than 18 months and short-term capital
gain taxable at a maximum rate of up to 39.6 percent if the shares been held for
only one year or less. In addition. any dividend declared by Cali in October,
November or December of any year payable to a stockholder of record on a
specific date in any such month shall be treated as both paid by Cali and
received by the stockholder on December 31 of such year provided that the
dividend is actually paid by Cali during January of the following calendar year.
Stockholders may not include in their individual income tax returns any net
operating losses or capital losses of Cali.
 
    As indicated above, pursuant to the Act, Cali may elect for taxable years of
Cali beginning on or after January 1, 1998, to retain any net capital gain
recognized by it and pay a corporate level tax on the undistributed amounts. The
maximum rate of tax applicable to corporate capital gains is 35 percent. To the
extent Cali recognized corporate level long-term capital gains which it retained
rather than distributing, a stockholder owning shares of Common Stock on
December 31 of the year in which such Retained Gains were recognized would be
required to include his proportionate share of the Retained Gains (as designated
by Cali in a notice mailed to the stockholder within the first 60 days of the
next year) in income for that year as long term capital gain. The stockholders
would be deemed to have paid the amount of tax paid by Cali with respect to the
Retained Gains and would be allowed a credit or refund for the tax deemed to be
paid by him. Stockholders receiving any such Retained Gains would increase their
adjusted tax basis in their shares of Common Stock by an amount equal to the
Retained Gains included in their income reduced by the amount of Company level
tax deemed to have been paid by them.
 
    In general, any loss upon a sale or exchange of shares of Common Stock by a
stockholder who has held such shares for six months or less (after applying
certain holding period rules) will be treated as a long-term capital loss to the
extent of actual or deemed distributions from Cali required to be treated by
such stockholder as long-term capital gain.
 
BACKUP WITHHOLDING
 
    Cali will report to its domestic stockholders and the IRS the amount of
dividends paid during each calendar year, and the amount of tax withheld, if any
with respect thereto. Under the backup withholding rules, a stockholder may be
subject to backup withholding at the rate of 31 percent with respect to
dividends paid unless such holder (a) is a corporation or comes within certain
other exempt categories and, when required, demonstrates this fact or (b)
provides a taxpayer identification number, certifies as to no loss of exemption
from backup withholding and otherwise complies with applicable requirements of
the backup withholding rules. A stockholder who does not provide Cali with its
correct taxpayer identification number may also be subject to penalties imposed
by the IRS. Any amount paid as backup withholding will be creditable against the
stockholder's income tax liability. In addition, Cali may be required to
withhold a portion of capital gain distributions made to any stockholders who
fail to certify their non-foreign status to Cali. See "--Taxation of Foreign
Stockholders" below.
 
TAXATION OF TAX-EXEMPT STOCKHOLDERS
 
    In applying the REIT stock ownership test under the Code, a pension trust
generally is not treated as a single individual as it would have been under
prior law. Instead, beneficiaries of certain pension trusts as holding the
shares of a REIT in proportion to their actuarial interests in such trust, and
thus permits certain pension trusts to acquire more concentrated ownership of a
REIT.
 
    In addition, a pension fund owning more than 10 percent of a REIT must treat
a percentage of dividends from the REIT as "unrelated business taxable income"
("UBTI"). The percentage is determined by dividing the REIT's gross income
derived from an unrelated trade or business for the year by the gross income of
the REIT for the year in which the dividends are paid. If this percentage is
less than five percent, however, dividends are not treated as UBTI. In general,
the UBTI rule applies to a REIT where
 
                                       73
<PAGE>
the REIT qualifies as a REIT by reason of the above modification of the stock
ownership test and (i) one pension trust owns more than 25% of the value of the
REIT; or (ii) a group of pension trusts individually holding more than 10% of
the value of the REIT collectively own more than 50% of the value of the REIT.
 
TAXATION OF FOREIGN STOCKHOLDERS
 
    The rules governing U.S. federal income taxation of nonresident alien
individuals, foreign corporations. foreign partnerships and other foreign
stockholders (collectively "Non-U.S. Stockholders") are complex. and no attempt
will be made herein to provide more than a limited summary of such rules.
Accordingly, the discussion does not address all aspects of U.S. federal income
tax and does not address state, local or foreign tax consequences (including
treaty benefits, if any, that may be available in certain instances) that may be
relevant to a Non-U.S. Stockholder in light of its particular circumstances. In
addition, this discussion is based on current law, which is subject to change,
and assumes that Cali qualifies for taxation as a REIT. Non-U.S. Stockholders
should consult with their own tax advisors to determine the impact of U.S.
federal, state and local income tax laws with regard to an investment in Common
Stock, including any reporting requirements.
 
    Distributions that are not attributable to gain from sales or exchanges by
Cali of U.S. real property interests and not designated by Cali as capital gain
dividends will be treated as dividends of ordinary income to the extent that
they are made out of current or accumulated earnings and profits of Cali. Such
distributions ordinarily will be subject to a withholding tax equal to 30% of
the gross amount of the distribution unless an applicable tax treaty reduces
that tax. However, if income from the investment in the shares of Common Stock
is treated as effectively connected with the Non-U.S. Stockholder's conduct of a
U.S. trade or business, the Non-U.S. Stockholder generally will be subject to a
tax at graduated rates, in the same manner as U.S. stockholders are taxed with
respect to such dividends (and may also be subject to the 30% branch profits tax
if the stockholder is a foreign corporation). Cali expects to withhold U.S.
income tax at the rate of 30% on the gross amount of any dividends paid to a
Non-U.S. Stockholder unless (i) a lower treaty rate applies and the required
form evidencing eligibility for that reduced rate is filed with Cali or (ii) the
Non-U.S. Stockholder files an IRS Form 4224 with Cali claiming that the
distribution is "effectively connected" income.
 
    Distributions in excess of current and accumulated earnings and profits of
Cali will not be taxable to a stockholder to the extent that they do not exceed
the adjusted basis of the stockholder's shares of Common Stock, but rather will
reduce the adjusted basis of such shares. To the extent that such distributions
exceed the adjusted basis of a Non-U.S. Stockholder's shares, they will give
rise to tax liability if the Non-U.S. Stockholder would otherwise be subject to
tax on any gain from the sale or disposition of his shares of Common Stock as
described below. If it cannot be determined at the time a distribution is made
whether or not such distribution will be in excess of current and accumulated
earnings and profits, the distribution will be subject to withholding at the
rate applicable to dividends. However, the Non-U.S. Stockholder may seek a
refund of such amounts from the IRS if it is subsequently determined that such
distribution was, in fact, in excess of current and accumulated earnings and
profits of Cali.
 
    Under recently proposed Treasury regulations, withholding procedures would
be revised. Should the proposal be adopted, withholding generally would be at
either 31 percent or 30 percent unless a new Form W-8 is filed with Cali by the
beneficial owner to establish entitlement to treaty benefits or exemption based
upon the income being "effectively connected". In some instances, additional
documentation might be required from the beneficial owner, including an
individual taxpayer identification number from the IRS and a certification of
tax status from the tax authorities of the beneficial owner's country of
residence.
 
    For any year in which Cali qualifies as a REIT, distributions that are
attributable to gain from sales or exchanges by Cali of U.S. real property
interests will be taxed to a Non-U.S. Stockholder under the provisions of the
Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA"). Under FIRPTA,
these distributions are taxed to a Non-U.S. Stockholder as if such gain were

business. Thus, Non-U.S. Stockholders would be taxed at the normal capital gain
rates applicable to U.S. stockholders (subject to applicable alternative minimum
tax and a special alternative minimum tax in the case of nonresident alien
individuals). Also, distributions subject to FIRPTA may be subject to a 30%
branch profits tax in the hands of a corporate Non-U.S. Stockholder not entitled
to treaty relief or exemption. Cali is required by applicable Treasury
Regulations to withhold 35 percent of any distribution that could be designated
by Cali as a capital gain dividend. This amount is creditable against the
Non-U.S. Stockholder's FIRPTA tax liability.
 
    Gain recognized by a Non-U.S. Stockholder upon a sale of Common Stock
generally will not be taxed under FIRPTA if a REIT is a "domestically controlled
REIT," defined generally as a REIT in which at all times during a specified
testing period less than 50 percent in value of the stock was held directly or
indirectly by foreign persons. It is currently anticipated that Cali will be a
"domestically controlled REIT," and therefore the sale of Common Stock will not
be subject to taxation under FIRPTA. However, gain not subject to FIRPTA will be
taxable to a Non-U.S. Stockholder if (i) investment in the Common Stock is
"effectively connected" with the Non-U.S. Stockholder's U.S. trade or business,
in which case the Non-U.S. Stockholder will be subject to the same treatment as
U.S. stockholders with respect to such gain, or (ii) the Non-U.S. Stockholder is
a nonresident alien individual who was present in the United States for 183 days
or more during the taxable year and has a "tax home" in the United States, in
which case the nonresident alien individual will be subject to a 30 percent U.S.
withholding tax on the individual's capital gains. If the gain on the sale of
Common Stock were to be subject to taxation under FIRPTA, the Non-U.S.
Stockholder would be subject to the same treatment as U.S. stockholders with
respect to such gain (subject to applicable alternative minimum tax, possible
withholding tax and a special alternative minimum tax in the case of nonresident
alien individuals).
 
EFFECT ON REIT QUALIFICATION OF TAX STATUS OF CRLP AND OTHER PARTNERSHIPS
 
    Substantially all of Cali's investments have been and will continue to be
through CRLP, which in turn will hold interests in other partnerships. The
ownership of an interest in a partnership involves special tax risks including
the possible challenge by the IRS of (i) allocations of income and expense
items, which could affect the computation of taxable income of Cali and (ii) the
status of the partnerships as partnerships (as opposed to associations taxable
as corporations) for income tax purposes. This partnership status risk should be
substantially diminished by Treasury Regulations issued on December 17, 1996,
permitting election of partnership status effective January 1, 1997 by the
filing of Form 8823 or in certain other ways specified in the new Regulations.
With respect to Cali's existing partnership investments, the new Regulations
provide that (1) previously claimed partnership status, if supported by a
reasonable basis for classification, will generally be respected for all periods
prior to January 1, 1997; and (2) previously claimed partnership status will
generally be retained after January 1, 1997, unless an entity elects to change
its status by filing a formal election. Cali believes that it has a reasonable
basis for the classification of CRLP and its subsidiary partnerships as
partnerships for federal income tax purposes and has neither filed nor does Cali
intend to file an election to have CRLP or any of its subsidiary partnerships
treated otherwise. If any of the partnerships, however, should be treated as an
association, it would be taxable as a corporation. In such a situation, if
Cali's ownership interest in any of the partnerships exceeded 10 percent of the
partnership's voting interests or the value of such interest exceeded 5 percent
of the value of Cali's assets, Cali would cease to qualify as a REIT.
Furthermore, in such a situation, distributions from any of the partnerships to
Cali would be treated as dividends, which are not taken into account in
satisfying the 75 percent gross income test described above and which could
therefore make it more difficult for Cali to meet the 75 percent asset test
described above. In addition, in such a situation, the interests in any of the
partnerships held by Cali would not qualify as a "real estate asset," which
could make it more difficult to meet the 75 percent asset test described above.
Finally, in such a situation, Cali would not be able to deduct its share of
losses generated by any of the partnerships in computing its taxable income. See
"-- Failure to Qualify as a REIT" above for a discussion of the effect of Cali's
failure to meet such tests for a taxable year. Cali believes that the
partnerships in which it owns interests have been and will continue to be
 
                                       75
<PAGE>
treated as partnerships (rather than as associations taxable as corporations)
for federal income tax purposes. However, no assurance can be given that the IRS
may not successfully challenge the status of any partnerships.
 
TAX ALLOCATIONS WITH RESPECT TO THE MACK PROPERTIES
 
    Pursuant to the Contribution and Exchange Agreement, Cali will acquire the
Mack Properties as a tax-free contribution to the capital of CRLP in exchange
for cash, the assumption of certain liabilities, Units and Warrants having an
aggregate value of approximately $1.2 billion dollars. Pursuant to Section 721
of the Code, no gain or loss will be recognized by CRLP or to any of its
partners (including Cali) as a result of the contribution of the Mack Properties
to CRLP in exchange for Units. Pursuant to Section 723 of the Code, CRLP's basis
of the Mack Properties shall be equal to the basis of such properties at the
time of contribution increased by the amount of any gain recognized by Mack upon
contribution. The aggregate adjusted tax basis of the Mack Properties at the
time of contribution is approximately $480 million dollars. Generally, the
difference between the fair market value of the contributed property
(approximately $1.2 billion dollars) at the time of contribution and the
adjusted tax basis of the Mack Properties or at the time of contribution
(approximately $480 million dollars) reflects that built-in-gain associated with
such Properties (the "Book -Tax Difference"). The Book-Tax Difference of the
Mack Properties acquired in the Mack Combination will be approximately $720
million dollars. As discussed below, CRLP and Cali will not be entitled to
depreciation deductions attributable to the Book-Tax Difference. As a result,
Cali will be required to distribute more dividends in order to satisfy a 95
percent distribution requirement than it would have had Cali purchased the
assets for cash in a taxable transaction. See "Annual Distribution Requirements"
above for a discussion of Cali's distribution requirements. In addition, the
amount of tax-free return of capital to each U.S. shareholder will be less than
the amount each shareholder would have realized had Cali purchased the assets
for cash in a taxable transaction.
 
    Pursuant to Section 704(c) of the Code, income, gain, loss, and deduction
attributable to appreciated property that is contributed to a partnership in
exchange for an interest in the partnership must be allocated for federal income
tax purposes in a manner such that the contributor is charged with the
unrealized gain associated with the property at the time of the contribution.
The partnership agreements of each of CRLP and its subsidiary or affiliated
partnerships require that allocations attributable to each item of contributed
property be made so as to allocate the tax depreciation available with respect
to such property first to the partners other than the partner that contributed
the property to the extent of, and in proportion to, their book depreciation,
and then, if any tax depreciation remains, to the partner that contributed the
property. Upon the disposition of any item of contributed property, any gain
attributable to an excess at such time of basis for book purposes over basis for
tax purposes would be allocated for tax purposes to the contributing partner.
These allocations are intended to be consistent with the Treasury Regulations
under Section 704(c) of the Code.
 
    In general, Mack will be allocated disproportionately lower amounts of
depreciation deductions for tax purposes relative to their percentage interests
in CRLP, and disproportionately greater shares relative to their percentage
interests in CRLP of the taxable income and gain on the sale of one or more of
the contributed Mack Properties. These tax allocations will tend to reduce or
eliminate the Book-Tax Difference over the life of the partnerships. The
Partnership Agreements of the partnerships adopt the "traditional method" in
allocating items allocable under Section 704(c) of the Code, unless otherwise
agreed to between Cali and the contributing partner. Pursuant to the
Contribution and Exchange Agreement, Cali has agreed to use the traditional
method for the Mack Properties. Under the traditional method, the amounts of the
special allocations of depreciation and gain under the special rules of Section
704(c) of the Code will be limited by the so-called "ceiling rule" and will not
always eliminate the Book-Tax Difference on an annual basis or with respect to a
specific transaction such as a sale. Thus, the carryover basis of the
contributed assets in the hands of the partnerships will cause Cali to be
allocated less depreciation than would be available for newly purchased
properties.

NEW WITHHOLDING REGULATIONS.
 
    Final regulations dealing with withholding tax on income paid to foreign
persons and related matters (the "New Withholding Regulations") were issued by
the Treasury Department on October 6, 1997. In general, the New Withholding
Regulations do not significantly alter the substantive withholding and
information reporting requirements, but unify current certification procedures
and forms and clarify reliance standards. For example, the New Withholding
Regulations adopt a certification rule which was in the proposed regulations,
under which a Non-U.S. Stockholder who wishes to claim the benefit of an
applicable treaty rate with respect to dividends received from a United States
corporation will be required to satisfy certain certification and other
requirements. In addition, the New Withholding Regulations require a corporation
that is a REIT to treat as a dividend the portion of a distribution that is not
designated as a capital gain dividend or return of basis and apply the 30%
withholding tax (subject to any applicable deduction or exemption) to such
portion, and to apply the FIRPTA withholding rules (discussed above) with
respect to the portion of the distribution designated by the REIT as capital
gain dividend. The New Withholding Regulations will generally be effective for
payment made after December 31, 1998, subject to certain transaction rules. THE
DISCUSSION SET FORTH ABOVE IN "TAXATION OF FOREIGN STOCKHOLDERS" DOES NOT TAKE
THE NEW WITHHOLDING REGULATIONS INTO ACCOUNT. PROSPECTIVE NON-U.S. STOCKHOLDERS
ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE NEW
WITHHOLDING REGULATIONS.
 
STATE AND LOCAL TAXES
 
    Cali and its stockholders may be subject to state or local taxation in
various state or local jurisdictions; including those in which it or they
transact business or reside. The state and local tax treatment of Cali and its
stockholders may not conform to the federal income tax consequences discussed
above. Consequently, prospective stockholders should consult their own tax
advisors regarding the effect of state and local tax laws on an investment in
the Common Stock of Cali.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon the completion of the Mack Combination, Cali will have outstanding
49,664,622 shares of Common Stock. In addition, 19,537,802 shares of Common
Stock are reserved for issuance upon the redemption of outstanding Units and the
exercise of outstanding options and Warrants. The shares of Common Stock
acquired by Mack in redemption of Units or the exercise of Warrants will be
"restricted securities" (the "Restricted Shares") within the meaning of Rule 144
("Rule 144") promulgated under the Securities Act of 1933, as amended (the
"Securities Act"), and may not be sold in the absence of registration under the
Securities Act unless an exemption from registration is available, including
exemptions contained in Rule 144.
 
    In general, under Rule 144 as currently in effect, if one year has elapsed
since the later of the acquisition of Restricted Shares from Cali or any
affiliate of Cali (as defined under the Securities Act), the acquiror or
subsequent holder thereof is entitled to sell within any three-month period a
number of shares that does not exceed the greater of (i) 1 percent of the then
outstanding shares of Common Stock of Cali or (ii) the average weekly trading
volume of the Common Stock during the four calendar weeks immediately preceding
the date on which notice of the sale is filed with the Securities and Exchange
Commission. Sales under Rule 144 are also subject to certain provisions relating
to manner of sale, notice, and the availability of current public information
about Cali. If two years have elapsed since the date of acquisition of
Restricted Shares from Cali or from any affiliate of Cali, and the acquiror or
subsequent holder therof is deemed not to have been an affiliate of Cali at any
time during the 90 days immediately preceding a sale, such person is entitled to
sell such shares in the public market under Rule 144(k) without regard to the
volume limitations, manner of sale provisions, public information requirements
or notice requirements.
 
    In connection with the Mack Combination, Cali has agreed to certain demand
and shelf registration rights to Mack with respect to the Common Stock obtained
upon the redemption of Units received in the Mack Combination. See "Description
of the Contribution and Exchange Agreement--Registration Rights".

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of
Cali Realty Corporation
and the Partners and Members of
The Mack Group
 
In our opinion, based upon our audits and the report of other auditors, the
accompanying combined balance sheets and the related combined statements of
operations, of partners' deficit and of cash flows, including financial
statement Schedule III, present fairly, in all material respects, the financial
position of The Mack Group at December 31, 1996 and 1995, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31 1996, in conformity with generally accepted accounting
principles. These financial statements and schedule are the responsibility of
the management of The Mack Group; our responsibility is to express an opinion on
these financial statements and schedule based on our audits. We did not audit
the combined financial statements and schedule of the Patriot American Office
Group, part of the combined Mack Group, which statements reflect total assets of
$129,573,000 and $127,434,000 at December 31, 1996 and 1995, respectively, and
total revenues of $38,373,000, $34,458,000 and $30,981,000 for the years ended
December 31, 1996, 1995 and 1994, respectively. Those statements were audited by
other auditors whose report thereon has been furnished to us, and our opinion
expressed herein, insofar as it relates to the amounts included for the Patriot
American Office Group, is based solely on the report of the other auditors. We
conducted our audits of these statements and schedule in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements and
schedule are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits and the report of other auditors provide a reasonable
basis for the opinion expressed above.

To the Partners and Owners
  Patriot American Office Group:
 
    We have audited the accompanying combined balance sheets of the Patriot
American Office Group, more fully described in Note 1, as of December 31, 1996
and 1995, and the related combined statements of operations, partners' and
owners' equity (deficit) and cash flows for each of the three years in the
period ended December 31, 1996 (not presented separately herein). We have also
audited the accompanying financial statement schedule (not presented separately
herein). These financial statements and schedule are the responsibility of the
Patriot American Office Group's management. Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of the Patriot
American Office Group as of December 31, 1996 and 1995, and the combined results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1996, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule
referred to above, when considered in relation to the basic financial statements
taken as a whole, presents fairly in all material respects the information
required to be set forth therein.

1. ORGANIZATION AND BASIS OF PRESENTATION
 
ORGANIZATION
 
    The Mack Group (not a legal entity) is engaged in the ownership and
operation of commercial office buildings located in the United States (the
"Properties"). The Properties are held through two portfolios: The Mack Company
and Patriot American Office ("PAO") portfolios. The Mack Company's office
property portfolio consists of 32 office properties comprising approximately 5.8
million square feet located principally in New Jersey and Arizona. The PAO
portfolio consists of 22 office properties comprising approximately 3.4 million
square feet located principally in Texas and Arizona. The Mack Company and PAO
are collectively hereinafter referred to as The Mack Group. Management, leasing
and construction services with respect to the Properties have been historically
provided by affiliates of The Mack Group.
 
BASIS OF PRESENTATION
 
    The accompanying combined financial statements of The Mack Group have been
presented on a combined basis, which is considered to be the most meaningful,
due to the common general partners in partnerships or managing members in
limited liability companies and common management. In addition, the entities are
expected to be the subject of a business combination with Cali Realty
Corporation and subsidiaries ("Cali"), a fully integrated, self administered,
self managed real estate investment trust. The business combination involves the
planned acquisition by Cali of 100 percent of the interests of the partners and
members of the partnerships and limited liability companies (hereinafter
referred to as "partnership or partnerships") included in The Mack Group who
will receive cash, limited partnership interests, warrants to acquire limited
partnership interests, or a combination thereof in Cali Realty, LP.
 
    Certain other properties and operations affiliated with The Mack Group have
been excluded from these financial statements as they are not included in the
anticipated business combination described above.
 
    All significant intercompany accounts and transactions have been eliminated
in combination.
 
    The following table sets forth the Properties included in The Mack Group as
of October 30, 1997:

period ended December 31, 1996, with the exception of the 120 Passaic Street,

UNAUDITED FINANCIAL STATEMENTS
 
    The combined financial statements including the note disclosures included
herein as of September 30, 1997 and for the nine months ended September 30, 1997
and 1996 are unaudited; however, in the opinion of management, all adjustments
(consisting solely of normal recurring adjustments) necessary for a fair
presentation of the combined financial statements for these interim periods have
been included. The results for the interim periods are not necessarily
indicative of the results to be obtained for the full fiscal year.

2. SIGNIFICANT ACCOUNTING POLICIES
 
RENTAL PROPERTY
 
    Rental properties are stated at cost less accumulated depreciation. Costs
include interest, property taxes, insurance and other project costs incurred
during the period of construction. Ordinary repairs and maintenance are expensed
as incurred; major replacements and betterments are capitalized. Depreciation is
computed on a straight-line basis over the estimated useful lives of the assets
as follows:
 
<TABLE>
<S>                                            <C>
Buildings and improvements...................  40 years
Tenant improvements..........................  The shorter of the term of the related lease
                                               or useful life
Furniture, fixtures and equipment............  5 to 10 years
</TABLE>
 
    On a periodic basis, management assesses whether there are any indicators
that the value of the real estate properties may be impaired. A property's value
is impaired only if management's estimate of the aggregate future cash flows
(undiscounted and without interest charges) to be generated by the property are
less than the carrying value of the property. Management does not believe that
the value of any of its real estate properties is impaired.
 
DEFERRED CHARGES AND OTHER ASSETS
 
    DEFERRED FINANCING COSTS
 
    Costs incurred to obtain financing are capitalized and amortized on a
straight-line basis, which approximated the effective interest method, over the
term of the related indebtedness. Amortization of such costs was $1,798, $664,
$892, $822, and $956 for the nine months ended September 30, 1997 and 1996 and
years ended December 31, 1996, 1995 and 1994, respectively.
 
    DEFERRED LEASING COSTS
 
    Direct costs, principally commissions and legal costs, incurred in
connection with leases are capitalized and amortized on a straight-line basis
over the terms of the related leases. Unamortized deferred leasing costs are
charged to amortization expense upon early termination of the lease.
 
    DEBT DISCOUNTS
 
    In connection with the initial acquisition and RTC financing of 21 of the
Properties (see Note 5), the carrying amount of the real estate and mortgage
notes payable were initially discounted by $40,961 using an effective interest
rate of 9.0 percent. The discount is amortized to interest expense over the
terms of the mortgage loans using the effective interest method.
 
    As more fully described in Note 5, The Mack Group determines the fair value
of the participation feature of the RTC participating mortgage at the inception
of the loan and records an increase in the mortgage note payable with a
corresponding debt discount. The debt discount is amortized into interest
expense using the effective interest method over the life of the loan. The
liability and debt discount are adjusted for subsequent changes in the fair
value of the participation feature and the revised debt discount is amortized
prospectively over the remaining life of the loan.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION
 
    The Mack Group recognizes base rental revenue on a straight-line basis over
the terms of the respective leases. Unbilled rents receivable represents the
amount by which straight-line rental revenue exceeds rents currently billed in
accordance with the lease agreements.
 
CASH AND CASH EQUIVALENTS
 
    All highly liquid investments with a maturity of three months or less when
purchased are considered to be cash equivalents. At September 30, 1997 and
December 31, 1996, cash and cash equivalents included investments in overnight
reverse repurchase agreements ("Overnight Investments") totaling $5,228 and
$2,172, respectively. Investments in Overnight Investments are subject to the
risks that the counter-party will default and the collateral will decline in
market value. The Overnight Investments matured on October 1, 1997 and on
January 2, 1997, and the entire balance, including interest income earned, was
realized by The Mack Group.
 
INTEREST RATE SWAP AND CAP AGREEMENTS
 
    The Mack Group has entered into interest rate swap and cap agreements to
reduce the impact of changes in interest rates on its floating rate mortgages.
The effect of these agreements is included in interest expense as incurred.
 
EXTRAORDINARY ITEM
 
    The extraordinary item represents the net effects resulting from the early
settlement of certain mortgage obligations, including accrued interest, net of
write-offs of related deferred financing costs.
 
PARTNERS' CAPITAL CONTRIBUTIONS, DISTRIBUTIONS AND PROFIT AND LOSS ALLOCATIONS
 
    The individual partnership agreements specify the required capital
contributions of the partners and the procedures for the allocation of profits,
losses, distributions and the return of capital to the partners. Generally,
these items are allocated in proportion to the respective ownership percentages
of the partners.
 
INCOME TAXES
 
    The entities included in the combined financial statements are partnerships
which are not subject to federal and state income taxes. The partners are
required to report in their individual federal and state income tax returns
their distributed share of income or loss and other amounts. Accordingly, income
taxes have not been provided for in the accompanying financial statements.
 
ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

3. RESTRICTED CASH
 
    Restricted cash includes escrow and reserve funds for debt service, real
estate taxes, property insurance, capital and tenant improvements, and leasing
costs established pursuant to certain mortgage and bond financing arrangements.
At December 31, 1995, restricted cash also included $1,653 of restricted
deposits made by a partner.

PAINE WEBBER MORTGAGES
 
    In December 1996, The Mack Group, in connection with the PAO portfolio, and
an affiliated property entered into a $126,000 mortgage loan agreement with
Paine Webber Incorporated ("Paine Webber"). Of this amount $9,354 is related to
and is collateralized by an affiliate's property, which is not among the
properties comprising The Mack Group. Accordingly, the accompanying financial
statements do not include the $9,354 of indebtedness associated with this
affiliated property. Proceeds from the loan were used to repay the RTC mortgages
and other loans, and accrued interest as discussed below. The loan,

which is collateralized by 21 Properties and a pledge of equity interest in one
partnership, an assignment of leases, and a cash collateral account, bears
interest at 250 basis points over the London Interbank Offer Rate ("LIBOR") for
the first nine months, 300 basis points over LIBOR for the following nine months
and 350 basis points over LIBOR thereafter until maturity in June 1998. LIBOR at
September 30, 1997 and December 31, 1996 was 5.63 percent and 5.53 percent,
respectively, and averaged 5.63 percent for the nine months ended September 30,
1997. At maturity, The Mack Group has the option to extend the loan to a
seven-year fixed rate mortgage, which would bear interest at the seven-year
Treasury rate plus 350 basis points. The loan may be prepaid in whole or part
without penalty. Additionally, The Mack Group has the option to borrow an
additional $7,000 to fund renovation costs at one of the Properties, subject to
the approval of Paine Webber. On October 2, 1997, The Mack Group borrowed $5,600
under this option.
 
    Under the terms of the loan, The Mack Group is required to deposit
substantially all revenues from the Properties into a cash collateral account
under the sole control of Paine Webber. Funds from the cash collateral account
are to be used to fund reasonable operating expenses, debt service, real estate
taxes, insurance and approved capital improvements. On a monthly basis, 70
percent of the remaining funds in the account are to be used to repay principal
on the Paine Webber mortgage loan and 30 percent are available to the The Mack
Group.
 
RESOLUTION TRUST CORPORATION (RTC)
 
    In connection with the acquisition of 21 of the PAO Properties in 1992, The
Mack Group obtained seller financing from the RTC in the form of individual
mortgage loans which aggregated $86,940. The mortgage loans matured from August
to December 2004, and were non-interest bearing for the first seven years, after
which time the loans bore interest at 9 percent per annum, payable quarterly. In
addition, the RTC was entitled to receive quarterly principal payments based on
operating income, as defined. Under the terms of the mortgage loans, the RTC was
also entitled to a 30 percent profit participation upon sale or refinancing of
the mortgage loans. The profit participation initially recorded in 1993 of
$6,287, was subsequently adjusted to $8,692 at December 31, 1994, $10,645 at
December 31, 1995 and $12,762 at December 27, 1996. The amortization of the
corresponding discount resulted in additional interest expense related to the
profit participation for the nine months ended September 30, 1996 and the years
ended December 31, 1996, 1995 and 1994 of approximately $970, $1,294, $1,029 and
$812, respectively.
 
    In December 1996, 20 of the 21 RTC mortgage loans, along with the unpaid
additional interest, were repaid with the proceeds of the Paine Webber mortgage
loan. As a result, The Mack Group recognized an extraordinary loss from early
extinguishment of debt of $31,717, which consisted primarily of the write-off of
the remaining unamortized debt discount of $21,835, the write-off of the
remaining unamortized discount related to the profit participation of $9,056 and
the write-off of deferred financing costs of $624. At September 30, 1997 and
December 31, 1996, one RTC mortgage loan remains with a carrying amount of
$3,486 and $3,264, net of discount of $848 and $1,073, respectively.
 
FIXED RATE MORTGAGES
 
    Interest rates on fixed rate mortgages aggregating $342,824, $347,854 and
$394,217 at September 30, 1997, and December 31, 1996 and 1995, respectively,
range from 7 percent to 14 percent, excluding the cash flow participation
discussed below. The effective interest rate at September 30, 1997 and December

31, 1996 and 1995 on such fixed rate mortgages was 8.97 percent, 9.05 percent
and 10.60 percent, respectively.
 
    In addition to the stated rates of interest, at September 30, 1997 and
December 31, 1996 and 1995, a $4,750 mortgage on one Property includes
provisions for additional interest based on 25 percent of cash flows, as
defined, of the underlying property pledged under the mortgage. Additional
interest for the nine months ended September 30, 1997, and 1996 and years ended
December 31, 1996, 1995, and 1994 was $217, $70, $93, $244, and $230,
respectively.
 
    On July 3, 1996, a second mortgage on the One Mack Center, Tampa, FL
property with an outstanding balance of $15,555 including unpaid interest of
$1,955 was canceled for a payment of $1,450 to the lender, which after the
write-off of related deferred financing costs resulted in an extraordinary gain
of $14,105.
 
VARIABLE RATE MORTGAGES
 
    The interest rate on variable rate mortgage payables of $12,376, $12,750 and
$15,816 at September 30, 1997 and December 31, 1996 and 1995, respectively, is
at the banks' prime rate or at prime plus 1 percent. The average effective
interest rate at September 30, 1997 and December 31, 1996 and 1995 was 8.50
percent, 8.25 percent and 6.68 percent, respectively.
 
    The interest rate on variable rate mortgage payables of $158,701, $161,471
and $162,312 at September 30, 1997 and December 31, 1996 and 1995, respectively,
is 0.55 percent to 2.25 percent above the LIBOR rate. The average effective
interest rate at September 30, 1997 and December 31, 1996 and 1995 was 7.26
percent, 7.24 percent and 8.11 percent, respectively. The average effective
interest rate for all variable rate mortgage payables for the nine months ended
September 30, 1997 and years ended December 31, 1996 and 1995 was 7.35 percent,
7.89 percent and 7.82 percent, respectively.
 
    Substantially all of the loans may not be prepaid until specified dates with
prepayment fees ranging from 1/2 percent to 2 percent of the outstanding
principal balance, or yield maintenance, as defined in the respective mortgage
loan agreement.
 
INDUSTRIAL DEVELOPMENT BONDS
 
    The Mack Manhasset, NY property is financed through the issuance of $8,000
of Nassau County IDA Bonds bearing interest at a bank's TENR rate (5.3 percent
at September 30, 1997 and 4.0 percent and 5.0 percent at December 31, 1996 and
1995, respectively) and maturing on December 1, 1999. These bonds are secured by
an $8.4 million letter of credit issued by a bank. Pursuant to the terms of the
letter of credit, the net cash flow of the Property is required to be deposited
into a sinking fund maintained by the bank as additional collateral; such
deposits, including interest totaled $885, $441 and $216 at September 30, 1997,
and December 31, 1996 and 1995, respectively.
 
INTEREST RATE SWAP AND CAP AGREEMENTS
 
    The Mack Group has entered into interest rate swap and cap agreements to
reduce the impact of changes in interest rates on its floating rate mortgages.
At December 31, 1996, The Mack Group had two outstanding swap agreements with
financial institutions, having an aggregate notional principal amount of

5. MORTGAGES AND BOND PAYABLE (CONTINUED)
$54,875. Those agreements effectively change The Mack Group's interest rate
exposure on its $11,875 floating rate (LIBOR + 1.15 percent) mortgage due
September 1999 to a fixed 7.08 percent through September 1998, and $43,000 of
its $53,000 floating rate (LIBOR + 0.55 percent) mortgage due January 2009 to a
fixed 8.029 percent through August 1997.
 
    At December 31, 1996, The Mack Group also has an outstanding interest rate
cap agreement with a financial institution, having a notional amount of $8,500.
This cap agreement effectively changes The Mack Group's interest rate exposure
on its $8,090 floating rate (LIBOR + 1.15 percent) mortgage due September 1999
to a maximum 9.65 percent through September 1998.
 
    The Mack Group is exposed to credit loss in the event of non-performance by
the other parties to the interest rate swap and cap agreements. However, The
Mack Group does not anticipate non-performance by the counter parties.

8. INCOME TAXES
 
    The entities included in the combined financial statements are partnerships
which are not subject to federal and state income taxes. Accordingly, no
recognition has been given to income taxes in the accompanying financial
statements since the income or loss of the entities are to be included in the
tax returns of the individual partners. The tax returns of the entities are
subject to examination by federal and state taxing authorities. If such
examinations result in adjustments to distributive shares of taxable income or
loss, the tax liability of the partners would be adjusted accordingly.
 
    The tax attributes of the partnerships' net assets flow directly to each
individual partner. Individual partners will have different investment bases
depending upon the timing and prices of their acquisition of partnership units.
Furthermore each partner's tax accounting, which is partially dependent upon
their individual tax position, may differ from the accounting followed in the
financial statements. Accordingly, there could be significant differences
between each individual partner's tax basis and their proportionate share of the
net assets reported in the financial statements.
 
9. DISCLOSURE OF FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The following disclosure of estimated fair value was determined by
management using available market information and appropriate valuation
methodologies. However, considerable judgment is necessary to interpret market
data and develop estimated fair value. Accordingly, the estimates presented
herein are not necessarily indicative of the amounts The Mack Group could
realize on disposition of the financial instruments at December 31, 1996. The
use of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts.
 
    Cash equivalents, receivables, accounts payable, and accrued expenses and
other liabilities are carried at amounts which reasonably approximate their fair
values.
 
    Mortgages and bond payable have an aggregate carrying value of $649,985 at
December 31, 1996, which approximates their estimated aggregate fair value
(excluding prepayment penalties) based upon then current interest rates for debt
with similar terms and remaining maturities.
 
    Based on the value of The Mack Group's interest rate swap and cap agreements
at December 31, 1996, the cost to The Mack Group to settle such agreements would
have been approximately $620.
 
    Disclosure about fair value financial instruments is based on pertinent
information available to management as of December 31, 1996. Although management
is not aware of any factors that would significantly affect the fair value
amounts, such amounts have not been comprehensively revalued for purposes of
these financial statements since December 31, 1996 and current estimates of fair
value may differ significantly from the amounts presented herein.
 
10. COMMITMENTS AND CONTINGENCIES
 
    The Mack Group has outstanding letters of credit issued by various banks
pledged as security for certain mortgages and bond payable. Letters of credit
outstanding as of September 30, 1997, December 31, 1996 and 1995, aggregated
$15,205, $15,620 and $19,965, respectively, and are not reflected on the
accompanying financial statements.

    One ground lease which expires December 2011 also provides additional rent
based 25 percent of cash flow, as defined, of the Property subject to the ground
lease. Such additional rents were $188, $99, $150, $201 and $169 for the nine
months ended September 30, 1997 and 1996 and years ended December 31, 1996, 1995
and 1994, respectively. Another ground lease which expires in February 2076
provides for additional ground rent beginning February 1997 based on 11% of cash
flow, as defined, of the Property subject to the ground lease. There was no such
additional rent due for the nine months ended September 30, 1997.
 
11. TENANT LEASES
 
    The Properties are leased to tenants under operating leases with various
expiration dates through 2014. Substantially all of the leases provide for
annual base rents plus recoveries and escalation charges based upon the tenant's
proportionate share of and/or increases in real estate taxes and certain
operating costs as defined and the pass through of charges for electrical usage.
Future minimum rentals to be received under non-cancelable operating leases at

Board of Directors
Cali Realty Corporation

Members of the Board:
 
    We understand that Cali Realty, L.P. ("CRLP") and Cali Realty Corporation
(collectively "Cali") and The Mack Company and Patriot American Office Group
(collectively "Mack") propose to enter into a transaction (the "Transaction")
pursuant to a Contribution and Exchange Agreement (the "Agreement") whereby Mack
will contribute certain properties (the "Mack Properties") to Cali in exchange
for $476,106,000 in cash (the "Cash"), 3,931,048 regular operating partnership
interests of CRLP (the "Common Units"), 249,656 cumulative preferred operating
partnership interests in CRLP (the "Preferred Units") and 2,000,000 warrants
(the "Warrants") to purchase shares of Cali's common stock (the "Common Stock")
and Cali will assume $302,147,000 in debt (the "Debt", and together with the
Cash, the Common Units, the Preferred Units and the Warrants, the
"Consideration").
 
    In connection with the Transaction, you have requested our opinion as to the
fairness to Cali from a financial point of view of the Consideration to be paid
in the Transaction.
 
    In conducting our analysis and arriving at the opinion set forth below, we
have reviewed such materials and considered such financial and other factors as
we deemed relevant under the circumstances, including, among others, the
following:
 
        1.  draft of the Agreement dated September 12, 1997;
 
        2.  draft of the audited combined financial statements for Mack for the
    year ended December 31, 1996 and a draft of the unaudited combined financial
    statements for the six months ended June 30, 1997;
 
        3.  certain publicly available historical financial and operating data
    for Cali including, but not limited to, (a) the Annual Report on Form 10-K
    for the fiscal year ended December 31, 1996, (b) the Proxy Statement for the
    Annual Meeting of Stockholders held on May 15, 1997, (c) the Quarterly
    Reports on Form 10-Q for the quarters ended March 31, 1997 and June 30,
    1997, (d) the Registration Statement on Form S-3, file No. 333-19101, dated
    January 7, 1997 and (e) a draft Form 8-K, dated September 18, 1997 relating
    to the Transaction.
 
        4.  certain financial forecasts for Cali and the Mack Properties
    provided to us by the management of Cali;
 
        5.  historical stock market prices and trading volume for Cali's common
    stock;
 
        6.  certain historical results of operations of Mack provided to us by
    the management of Mack;
 
        7.  publicly available information including financial, operating and
    stock market data concerning certain companies engaged in businesses we
    deemed comparable to Mack or otherwise relevant to our inquiry;
 
        8.  the financial terms of other transactions we deemed relevant;
 
        9.  the pro forma financial impact of the Transaction on Cali; and
 
        10. such other financial studies, analyses and investigations as we
    deemed appropriate.
<PAGE>
    We have met with the senior management of Cali and of Mack regarding (i) the
prospects and business plans for Cali and Mack, (ii) their financial forecasts
for Cali and the Mack Properties, and (iii) such other matters we deemed
relevant.
 
    We have assumed, with your consent, that the draft of the Agreement which we
reviewed will conform, in all material respects, to the Agreement when in final
form.
 
    In connection with our review and analysis and in arriving at our opinion,
we have, with your consent, also assumed and relied upon the accuracy and
completeness of publicly available information and all information supplied or
otherwise made available to us by Cali and Mack, and we have not independently
verified such information. We have neither made nor obtained any independent
evaluation of such information or any independent valuation or appraisal of the
assets or liabilities of either Cali or Mack.
 
    With respect to the pro forma financial information regarding Cali provided
to us by Cali and the financial forecasts for the Mack Properties provided to us
by Cali, we have assumed that they have been reasonably prepared and reflect the
best currently available estimates and judgment of Cali's and Mack's management
as to the expected future financial performance of Cali and Mack and we have not
undertaken any independent analysis to verify the reasonableness of the
assumptions underlying such forecasts. Further, our opinion is necessarily based
upon information available to us and on economic, financial, market and other
conditions as they exist and can only be evaluated as of the date hereof.
 
    No limitations were imposed on, or instructions given by either Cali or
Mack, with respect to our investigation or the procedures we followed in
rendering our opinion, and the management of Cali and Mack cooperated fully in
connection with our investigation.
 
    As you know, we have been retained by Cali to render this opinion and other
financial advisory services in connection with the Transaction and will receive
a fee for such services, which fee is contingent upon consummation of the
Transaction. In the past, we have provided financing and advisory services for
Cali and received compensation for such services. In addition, we make a market
in the Common Stock and in the ordinary course of business may actively trade
the Common Stock for our own account or for the accounts of customers and,
accordingly, may at any time hold a long or short position in the Common Stock.
Prudential Securities also provides equity research coverage for Cali.
 
    Our advisory services and the opinion expressed herein are provided for the
use of the Board of Directors of Cali in its evaluation of the Transaction, and
our opinion is not intended to be, and does not constitute a recommendation to
any shareholder of Cali as to how such shareholder should vote in connection
with the Transaction. This opinion may not be disclosed publicly, referred to or
communicated by you in any manner without our prior written approval and this
opinion must be treated as confidential; except that Cali may include this
opinion in its entirety in any proxy statement or information statement relating
to the Transaction sent to Cali's shareholders.
 
    On the basis of, and subject to, the foregoing, we are of the opinion that,
as of the date hereof, the Consideration to be paid by Cali pursuant to the
Transaction is fair, from a financial point of view, to Cali.
 
                                        Very truly yours,
 
                                        Prudential Securities Incorporated
