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

     (a) Committee.  The Plan shall be administered by either the Board or a
committee of not less than two Independent Directors (in either case, the
"Administrator").  Each member of the Committee shall be a "non-employee
director" within the meaning of Rule 16b-3(b)(3)(i) promulgated under the Act,
or any successor definition under said rule. Each member of the Committee shall
also be an "outside director" within the meaning of Section 162(m) of the Code
and the regulations promulgated thereunder.

     (b) Powers of Administrator.  The Administrator shall have the power and
authority to grant Awards consistent with the terms of the Plan, including the
power and authority:

          (i) to select the individuals to whom Awards may from time to time be
     granted;

          (ii) to determine the time or times of grant, and the extent, if any,
     of Incentive Stock Options, Non-Qualified Stock Options, Restricted Stock
     Awards, Deferred Stock Awards, Unrestricted Stock Awards, Performance Share
     Awards, Dividend Equivalent Rights and Other Stock-Based Awards, or any
     combination of the foregoing, granted to any one or more participants;

          (iii)  to determine the number of shares of Stock to be covered by any
     Award;

          (iv) to determine and modify from time to time the terms and
     conditions, including restrictions, not inconsistent with the terms of the
     Plan, of any Award, which terms and conditions may differ among individual
     Awards and participants, and to approve the form of written instruments
     evidencing the Awards; provided, however, that except as otherwise provided
     in Section 3(b) or 3(c), the Administrator is not permitted to reduce the
     exercise price of stock options or effect repricing through cancellation
     and re-grants;

          (v) to accelerate at any time the exercisability or vesting of all or
     any portion of any Award in circumstances involving a Change of Control or
     the death, disability or termination of employment of a Plan participant;

          (vi) subject to the provisions of Section 5(a)(iii), to extend at any
     time the post-termination period in which Stock Options may be exercised;

                                       3
<PAGE>

          (vii)  to determine at any time whether, to what extent, and under
     what circumstances Stock and other amounts payable with respect to an Award
     shall be deferred either automatically or at the election of the
     participant and whether and to what extent the Company shall pay or credit
     amounts constituting deemed interest (at rates determined by the
     Administrator) or dividends or deemed dividends on such deferrals; and

          (viii)  at any time to adopt, alter and repeal such rules, guidelines
     and practices for administration of the Plan and for its own acts and
     proceedings as it shall deem advisable; to interpret the terms and
     provisions of the Plan and any Award (including related written
     instruments); to make all determinations it deems advisable for the
     administration of the Plan; to decide all disputes arising in connection
     with the Plan; and to otherwise supervise the administration of the Plan.

     All decisions and interpretations of the Administrator shall be made in the
Administrator's sole and absolute discretion and shall be final and binding on
all persons, including the Company and Plan participants.

     (c) Delegation of Authority to Grant Awards.  The Administrator, in its
discretion, may delegate to the Chief Executive Officer of the Company all or
part of the Administrator's authority and duties with respect to Awards,
including the granting thereof, to individuals who are not subject to the
reporting and other provisions of Section 16 of the Act or "covered employees"
within the meaning of Section 162(m) of the Code.  Any such delegation by the
Administrator shall include a limitation as to the amount of Awards that may be
awarded during the period of the delegation and shall contain guidelines as to
the determination of the exercise price of any Option, the conversion ratio or
price of other Awards and the vesting criteria.  The Administrator may revoke or
amend the terms of a delegation at any time but such action shall not invalidate
any prior actions of the Administrator's delegate or delegates that were
consistent with the terms of the Plan.

SECTION 3.  STOCK ISSUABLE UNDER THE PLAN; RECAPITALIZATIONS; MERGERS;
            ----------------------------------------------------------
            SUBSTITUTE AWARDS
            -----------------

     (a) Stock Issuable.  The maximum number of shares of Stock reserved and
available for issuance under the Plan shall be increased from 9,699,162 shares
to 14,699,162 shares as of the date of this restatement, an increase of
5,000,000 shares; plus (ii) as of the first day of each calendar quarter after
January 1, 2000, 9.5 percent of any net increase since the first day of the
preceding calendar quarter in the total number of shares of Stock actually
outstanding (assuming all units of partnership interests in the Operating
Partnership that are subject to redemption rights are converted into Stock).
Notwithstanding the foregoing, the maximum number of shares of Stock for which
Awards other than Options may be granted under the Plan shall not exceed
2,000,000 shares in the aggregate.  The foregoing limitation shall apply to
shares available for issuance under the Plan prior to this restatement as well
as shares added to the Plan as a result of this restatement.  For purposes of
the limitations of this

                                       4
<PAGE>

Section 3(a), if any portion of an Award is forfeited, cancelled, reacquired by
the Company, satisfied without the issuance of Stock or otherwise terminated,
the shares of Stock underlying such portion of the Award shall be added back to
the shares of Stock available for issuance under the Plan. With respect to
grants made or compensation earned under the Plan, Stock Options with respect to
no more than 1,500,000 shares of Stock may be granted to any one individual
participant during any one calendar year period. The shares available for
issuance under the Plan may be authorized but unissued shares of Stock or shares
of Stock reacquired by the Company.

     (b) Recapitalizations.  If, through or as a result of any merger,
consolidation, sale of all or substantially all of the assets of the Company,
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split or other similar transaction, the outstanding shares of
Stock are increased or decreased or are exchanged for a different number or kind
of shares or other securities of the Company, or additional shares or new or
different shares or other securities of the Company or other non-cash assets are
distributed with respect to such shares of Stock or other securities, the
Administrator may make an appropriate or proportionate adjustment in (i) the
maximum number of shares reserved for issuance under the Plan, (ii) the number
of Stock Options that can be granted to any one individual participant, (iii)
the number and kind of shares or other securities subject to any then
outstanding Awards under the Plan, and (iv) the price for each share subject to
any then outstanding Stock Options under the Plan, without changing the
aggregate exercise price (i.e., the exercise price multiplied by the number of
Stock Options) as to which such Stock Options remain exercisable.  The
adjustment by the Administrator shall be final, binding and conclusive.  No
fractional shares of Stock shall be issued under the Plan resulting from any
such adjustment, but the Administrator in its discretion may make a cash payment
in lieu of fractional shares.

     (c) Mergers.  In contemplation of and subject to the consummation of a
consolidation or merger or sale of all or substantially all of the assets of the
Company in which outstanding shares of Stock are exchanged for securities, cash
or other property of an unrelated corporation or business entity or in the event
of a liquidation of the Company (in each case, a "Transaction"), the Board, or
the board of directors of any corporation assuming the obligations of the
Company, may, in its discretion, take any one or more of the following actions,
as to outstanding Awards:  (i) provide that such Awards shall be assumed or
equivalent awards shall be substituted, by the acquiring or succeeding
corporation (or an affiliate thereof), and/or (ii) upon written notice to the
participants, provide that all Awards will terminate immediately prior to the
consummation of the Transaction.  In the event that, pursuant to clause (ii)
above, Awards will terminate immediately prior to the consummation of the
Transaction, all vested Awards, other than Options, shall be fully settled in
cash or in kind  at such appropriate consideration as determined by the
Administrator in its sole discretion after taking into account the consideration
payable per share of Stock pursuant to the business combination (the "Merger
Price") and all Stock Options shall be fully settled, in cash or in kind, in an
amount equal to the difference between (A) the Merger Price times the number of
shares of Stock subject to such outstanding Stock Options (to the extent then
exercisable at prices not in excess of the Merger Price) and (B) the aggregate
exercise price of all such

                                       5
<PAGE>

outstanding Stock Options; provided, however, that each participant shall be
permitted, within a specified period determined by the Administrator prior to
the consummation of the Transaction, to exercise all outstanding Stock Options,
including those that are not then exercisable, subject to the consummation of
the Transaction.

     (d) Substitute Awards.  The Administrator may grant Awards under the Plan
in substitution for stock and stock based awards held by employees of another
corporation who become employees of the Company or a Subsidiary as the result of
a merger or consolidation of the employing corporation with the Company or a
Subsidiary or the acquisition by the Company or a Subsidiary of property or
stock of the employing corporation.  The Administrator may direct that the
substitute awards be granted on such terms and conditions as the Administrator
considers appropriate in the circumstances.

SECTION 4.  ELIGIBILITY
            -----------

     Participants in the Plan will be such full or part-time officers and other
employees, Independent Directors and key persons of the Company, the Operating
Partnership and the Company's other Subsidiaries who are responsible for or
contribute to the management, growth or profitability of the Company, the
Operating Partnership and the Company's other Subsidiaries as are selected from
time to time by the Administrator in its sole discretion.

SECTION 5.  STOCK OPTIONS
            -------------

     Any Stock Option granted under the Plan shall be in such form as the
Administrator may from time to time approve.

     Stock Options granted under the Plan may be either Incentive Stock Options
or Non-Qualified Stock Options.  Incentive Stock Options may be granted only to
employees of the Company or any Subsidiary that is a "subsidiary corporation"
within the meaning of Section 424(f) of the Code.  To the extent that any Option
does not qualify as an Incentive Stock Option, it shall be deemed a Non-
Qualified Stock Option.

     No Incentive Stock Option shall be granted under the Plan after January 24,
2010.

     (a) Stock Options Granted to Employees and Key Persons.  The Administrator
in its discretion may grant Stock Options to eligible employees and key persons
of the Company or any Subsidiary.  Stock Options granted pursuant to this
Section 5(a) shall be subject to the following terms and conditions and shall
contain such additional terms and conditions, not inconsistent with the terms of
the Plan, as the Administrator shall deem desirable.  If the Administrator so
determines, Stock Options may be granted in lieu of cash compensation at the
participant's election, subject to such terms and conditions as the
Administrator may establish, as well as in addition to other compensation.

                                       6
<PAGE>

          (i) Exercise Price.  The exercise price per share for the Stock
     covered by a Stock Option granted pursuant to this Section 5(a) shall be
     determined by the Administrator at the time of grant but shall not be less
     than 100 percent of the Fair Market Value on the date of grant (other than
     options granted in lieu of cash compensation).  If an employee owns or is
     deemed to own (by reason of the attribution rules of Section 424(d) of the
     Code) more than 10 percent of the combined voting power of all classes of
     stock of the Company or any parent or subsidiary corporation and an
     Incentive Stock Option is granted to such employee, the option price of
     such Incentive Stock Option shall be not less than 110 percent of the Fair
     Market Value on the grant date.

          (ii) Option Term.  The term of each Stock Option shall be fixed by the
     Administrator, but no Option shall be exercisable more than ten years after
     the date the option is granted.  If an employee owns or is deemed to own
     (by reason of the attribution rules of Section 424(d) of the Code) more
     than 10 percent of the combined voting power of all classes of stock of the
     Company or any parent or subsidiary corporation and an Incentive Stock
     Option is granted to such employee, the term of such option shall be no
     more than five years from the date of grant.

          (iii)  Exercisability; Rights of a Stockholder.  Stock Options shall
     become exercisable at such time or times, whether or not in installments,
     as shall be determined by the Administrator at or after the grant date;
     provided, however, that Stock Options granted in lieu of compensation shall
     be exercisable in full as of the grant date unless the Administrator
     otherwise provides in the Award agreement; provided further, however, that
     an optionee's Stock Options, other than those held by Mortimer B. Zuckerman
     and Edward H. Linde, shall be exercisable in full upon and after such
     optionee's attainment of age 65.  The Administrator may at any time
     accelerate the exercisability of all or any portion of any Stock Option.
     An optionee shall have the rights of a stockholder only as to shares
     acquired upon the exercise of a Stock Option and not as to unexercised
     Stock Options.

          (iv) Method of Exercise.  Stock Options may be exercised in whole or
     in part, by giving written notice of exercise to the Company, specifying
     the number of shares to be purchased.  Payment of the purchase price may be
     made by one or more of the following methods to the extent provided in the
     Option Award agreement:

               (A) In cash, by certified or bank check or other instrument
          acceptable to the Administrator;

               (B) Through the delivery (or attestation to the ownership) of
          shares of Stock that are not then subject to restrictions under any
          Company plan and that have been beneficially owned by the optionee for
          at least six months, if permitted by the Administrator in its
          discretion.  Such surrendered shares shall be valued at Fair Market
          Value on the exercise date;

                                       7
<PAGE>

               (C) By the optionee delivering to the Company a properly executed
          exercise notice together with irrevocable instructions to a broker to
          promptly deliver to the Company cash or a check payable and acceptable
          to the Company to pay the purchase price; provided that in the event
          the optionee chooses to pay the purchase price as so provided, the
          optionee and the broker shall comply with such procedures and enter
          into such agreements of indemnity and other agreements as the
          Administrator shall prescribe as a condition of such payment
          procedure; or

               (D) By the optionee delivering to the Company a promissory note
          if the Administrator has expressly authorized the loan of funds to the
          optionee for the purpose of enabling or assisting the optionee to
          effect the exercise of his Stock Option; provided that at least so
          much of the exercise price as represents the par value of the Stock
          shall be paid other than with a promissory note.

     Payment instruments will be received subject to collection.  The delivery
     of certificates representing the shares of Stock to be purchased pursuant
     to the exercise of a Stock Option will be contingent upon receipt from the
     optionee (or a purchaser acting in his stead in accordance with the
     provisions of the Stock Option) by the Company of the full purchase price
     for such shares and the fulfillment of any other requirements contained in
     the Stock Option or applicable provisions of laws.  In the event an
     optionee chooses to pay the purchase price by previously-owned shares of
     Stock through the attestation method, the number of shares of Stock
     transferred to the optionee upon the exercise of the Stock Option shall be
     net of the shares attested to.

          (v) Annual Limit on Incentive Stock Options.  To the extent required
     for "incentive stock option" treatment under Section 422 of the Code, the
     aggregate Fair Market Value (determined as of the time of grant) of the
     shares of Stock with respect to which Incentive Stock Options granted under
     this Plan and any other plan of the Company or its parent and subsidiary
     corporations become exercisable for the first time by an optionee during
     any calendar year shall not exceed $100,000.  To the extent that any Stock
     Option exceeds this limit, it shall constitute a Non-Qualified Stock
     Option.

     (b) Reload Options.  At the discretion of the Administrator and subject to
such restrictions, terms and conditions as the Administrator may establish,
Options granted under the Plan may include a "reload" feature pursuant to which
an optionee exercising an option by the delivery of a number of shares of Stock
in accordance with Section 5(a)(iv)(B) hereof would automatically be granted an
additional Option (with an exercise price equal to the Fair Market Value of the
Stock on the date the additional Option is granted and with such other terms as
the Administrator may provide) to purchase that number of shares of Stock equal
to the number delivered to exercise the original Option with an Option term
equal to the remainder of the original Option term unless the Administrator
otherwise determines in the Award agreement for the original Option grant.

                                       8
<PAGE>

     (c) Stock Options Granted to Independent Directors.

          (i)  Automatic Grant of Options.

               (A) Each person who was an Independent Director on the effective
          date of the Company's initial public offering was granted on such date
          a Non-Qualified Stock Option to acquire 10,000 shares of Stock.  The
          exercise price per share for the Stock covered by such Non-Qualified
          Stock Option shall be the initial public offering price as set forth
          in the final prospectus for the Company's initial public offering.

               (B) Each Independent Director who is first elected to serve as a
          Director after the effective date of the Company's initial public
          offering shall be granted, on the fifth business day after his
          election, a Non-Qualified Stock Option to acquire 10,000 shares of
          Stock.

               (C) Each Independent Director who is serving as Director of the
          Company on the fifth business day after each annual meeting of
          shareholders, beginning with the 1998 annual meeting, shall
          automatically be granted on such day a Non-Qualified Stock Option to
          acquire 5,000 shares of Stock.

               (D) The exercise price per share for the Stock covered by a Stock
          Option granted under this Section 5(c)(i)(B) and (C) shall be equal to
          the Fair Market Value of the Stock on the date the Stock Option is
          granted.

               (E) The Board, in its discretion, may grant additional Non-
          Qualified Stock Options to Independent Directors.  Any such grant may
          vary among individual Independent Directors.

          (ii)  Exercise; Termination.

               (A) Unless otherwise determined by the Administrator, an Option
          granted under Section 5(c)(i)(A), (B) or (C) shall be exercisable with
          respect to 50 percent of the underlying shares on the first
          anniversary of the grant date and shall be exercisable with respect to
          all of the underlying shares on the second anniversary of the grant
          date.  An Option granted under Section 5(c)(i)(E) shall be subject to
          such vesting and exercisability provisions as the Board may provide at
          the time of grant.  An Option issued under this Section 5(c) shall not
          be exercisable after the expiration of ten years from the date of
          grant.

               (B) Options granted under this Section 5(c) may be exercised only
          by written notice to the Company specifying the number of shares to be
          purchased.  Payment of the full purchase price of the shares to be
          purchased may be made by one or more of the methods specified in
          Section 5(a)(iv).  An optionee shall

                                       9
<PAGE>

          have the rights of a stockholder only as to shares acquired upon the
          exercise of a Stock Option and not as to unexercised Stock Options.

     (d) Non-transferability of Options.  No Stock Option shall be transferable
by the optionee otherwise than by will or by the laws of descent and
distribution and all Stock Options shall be exercisable, during the optionee's
lifetime, only by the optionee.  Notwithstanding the foregoing, the
Administrator, in its sole discretion, may provide in the Award agreement
regarding a given Option that the optionee may transfer, without consideration
for the transfer, his Non-Qualified Stock Options to members of his family, to
trusts for the benefit of such family members, or to partnerships in which such
family members are the only partners, provided that the transferee agrees in
writing with the Company to be bound by all of the terms and conditions of this
Plan and the applicable option agreement.

     (e)  Termination.

          (i) Except as may otherwise be provided by the Administrator either in
     the Award agreement, or subject to Section 14 below, in writing after the
     Award agreement is issued, an optionee's rights in all Stock Options shall
     automatically terminate upon the participant's termination of employment
     (or cessation of business relationship) with the Company and its
     Subsidiaries for any reason, except by reason of Retirement.

          (ii) Any Stock Option held by an optionee, other than Mortimer B.
     Zuckerman and Edward H. Linde, whose employment by the Company and its
     Subsidiaries is terminated by reason of Retirement may thereafter be
     exercised, to the extent it was exercisable at the time of such
     termination, for a period of 24 months (or such other period as the
     Administrator shall specify at any time) from the date of such termination
     of employment by reason of Retirement, or until the expiration of the
     stated term of the Stock Option, if earlier.

SECTION 6.  RESTRICTED STOCK AWARDS
            -----------------------

     (a) Nature of Restricted Stock Awards.  A Restricted Stock Award is an
Award entitling the recipient to acquire, at par value or such other higher
purchase price determined by the Administrator, shares of Stock subject to such
restrictions and conditions as the Administrator may determine at the time of
grant ("Restricted Stock").  Conditions may be based on continuing employment
(or other business relationship) and/or achievement of pre-established
performance goals and objectives.  The grant of a Restricted Stock Award is
contingent on the participant executing the Restricted Stock Award agreement.
The terms and conditions of each such agreement shall be determined by the
Administrator, and such terms and conditions may differ among individual Awards
and participants.

                                       10
<PAGE>

     (b) Rights as a Stockholder.  Upon execution of the Restricted Stock Award
agreement and paying any applicable purchase price, a participant shall have the
rights of a stockholder with respect to the voting of the Restricted Stock,
subject to such terms and conditions as may be contained in the Restricted Stock
Award agreement.  Unless the Administrator shall otherwise determine,
certificates evidencing the Restricted Stock shall remain in the possession of
the Company until such Restricted Stock is vested as provided in Section 6(d)
below, and the participant shall be required, as a condition of the grant, to
deliver to the Company a stock power endorsed in blank.

     (c) Restrictions.  Restricted Stock may not be sold, assigned, transferred,
pledged or otherwise encumbered or disposed of except as specifically provided
herein or in the Restricted Stock Award agreement.  If a participant's
employment (or other business relationship) with the Company and its
Subsidiaries terminates for any reason, the Company shall have the right to
repurchase Restricted Stock that has not vested at the time of termination at
its original purchase price, from the participant or the participant's legal
representative.

     (d) Vesting of Restricted Stock.  The Administrator at the time of grant
shall specify the date or dates and/or the attainment of pre-established
performance goals, objectives and other conditions on which the non-
transferability of the Restricted Stock and the Company's right of repurchase or
forfeiture shall lapse.  Subsequent to such date or dates and/or the attainment
of such pre-established performance goals, objectives and other conditions, the
shares on which all restrictions have lapsed shall no longer be Restricted Stock
and shall be deemed "vested."  The vesting period of a Restricted Stock Award
shall be at least three years, except that in the case of a Restricted Stock
Award that may become transferable and no longer subject to forfeiture upon the
attainment of pre-established performance goals, the vesting period shall be at
least one year.  Except as may otherwise be provided by the Administrator either
in the Award agreement or, subject to Section 14 below, in writing after the
Award agreement is issued, a participant's rights in any shares of Restricted
Stock that have not vested shall automatically terminate upon the participant's
termination of employment (or other business relationship) with the Company and
its Subsidiaries and such shares shall be subject to the Company's right of
repurchase as provided in Section 6(c) above.

     (e) Waiver, Deferral and Reinvestment of Dividends.  The Restricted Stock
Award agreement may require or permit the immediate payment, waiver, deferral or
reinvestment (in the form of additional Restricted Stock) of dividends paid on
the Restricted Stock.

SECTION 7.  DEFERRED STOCK AWARDS
            ---------------------

     (a) Nature of Deferred Stock Awards.   A Deferred Stock Award is an Award
of phantom stock units to a participant, subject to restrictions and conditions
as the Administrator may determine at the time of grant.  Conditions may be
based on continuing employment (or other business relationship) and/or
achievement of pre-established performance goals and

                                       11
<PAGE>

objectives. Except in the case of Deferred Stock Awards granted pursuant to
Section 7(b) below, the vesting period of a Deferred Stock Award shall be at
least three years, except that in the case of a Deferred Stock Award that may
become transferable and no longer subject to forfeiture upon the attainment of
pre-established performance goals, the vesting period shall be at least one
year. The grant of a Deferred Stock Award is contingent on the participant
executing the Deferred Stock Award agreement. The terms and conditions of each
such agreement shall be determined by the Administrator, and such terms and
conditions may differ among individual Awards and participants. At the end of
the deferral period, the Deferred Stock Award, to the extent vested, shall be
paid to the participant in the form of shares of Stock.

     (b) Election to Receive Deferred Stock Awards in Lieu of Compensation.  The
Administrator may, in its sole discretion, permit a participant to elect to
receive a portion of the cash compensation or Restricted Stock Award otherwise
due to such participant in the form of a Deferred Stock Award.  Any such
election shall be made in writing and shall be delivered to the Company no later
than the date specified by the Administrator and in accordance with rules and
procedures established by the Administrator.  The Administrator shall have the
sole right to determine whether and under what circumstances to permit such
elections and to impose such limitations and other terms and conditions thereon
as the Administrator deems appropriate.

     (c) Rights as a Stockholder.  During the deferral period, a participant
shall have no rights as a stockholder; provided, however, that the participant
may be credited with Dividend Equivalent Rights with respect to the phantom
stock units underlying his Deferred Stock Award, subject to such terms and
conditions as the Administrator may determine.

     (d) Restrictions.  A Deferred Stock Award may not be sold, assigned,
transferred, pledged or otherwise encumbered or disposed of during the deferral
period.

     (e) Termination.  Except as may otherwise be provided by the Administrator
either in the Award agreement or, subject to Section 14 below, in writing after
the Award agreement is issued, a participant's right in all Deferred Stock
Awards that have not vested shall automatically terminate upon the participant's
termination of employment (or cessation of business relationship) with the
Company and its Subsidiaries for any reason.

SECTION 8.  UNRESTRICTED STOCK AWARDS
            -------------------------

     Grant or Sale of Unrestricted Stock.  The Administrator may, in its sole
discretion, grant (or sell at par value or such other higher purchase price
determined by the Administrator) an Unrestricted Stock Award to any participant
pursuant to which such participant may receive shares of Stock free of any
restrictions ("Unrestricted Stock") under the Plan.  Unrestricted Stock Awards
may be granted or sold as described in the preceding sentence in respect of past
services or other valid consideration, or in lieu of any cash compensation due
to such participant.

                                       12
<PAGE>

SECTION 9.  PERFORMANCE SHARE AWARDS
            ------------------------

     (a) Nature of Performance Share Awards.  A Performance Share Award is an
Award entitling the recipient to acquire shares of Stock upon the attainment of
specified performance goals.  The Administrator may make Performance Share
Awards independent of or in connection with the granting of any other Award
under the Plan.  The Administrator in its sole discretion shall determine
whether and to whom Performance Share Awards shall be made, the performance
goals applicable under each such Award, the periods during which performance is
to be measured, and all other limitations and conditions applicable to the
awarded Performance Shares; provided, however, that the Administrator may rely
on the performance goals and other standards applicable to other performance
unit plans of the Company in setting the standards for Performance Share Awards
under the Plan.

     (b) Rights as a Stockholder.  A participant receiving a Performance Share
Award shall have the rights of a stockholder only as to shares actually received
by the participant under the Plan and not with respect to shares subject to the
Award but not actually received by the participant.  A participant shall be
entitled to receive a stock certificate evidencing the acquisition of shares of
Stock under a Performance Share Award only upon satisfaction of all conditions
specified in the written instrument evidencing the Performance Share Award (or
in a performance plan adopted by the Administrator).

     (c) Termination.  Except as may otherwise be provided by the Administrator
either in the Award agreement or, subject to Section 14 below, in writing after
the Award agreement is issued, a participant's rights in all Performance Share
Awards shall automatically terminate upon the participant's termination of
employment (or cessation of business relationship) with the Company and its
Subsidiaries for any reason.

     (d) Acceleration, Waiver, Etc.  At any time prior to the participant's
termination of employment (or other business relationship) by the Company and
its Subsidiaries, the Administrator may in its sole discretion accelerate, waive
or, subject to Section 14, amend any or all of the goals, restrictions or
conditions imposed under any Performance Share Award.

SECTION 10.  DIVIDEND EQUIVALENT RIGHTS
             --------------------------

     (a) Dividend Equivalent Rights.  A Dividend Equivalent Right is an Award
entitling the recipient to receive credits based on cash dividends that would
have been paid on the shares of Stock specified in the Dividend Equivalent Right
(or other award to which it relates) if such shares had been issued to and held
by the recipient.  A Dividend Equivalent Right may be granted hereunder to any
participant as a component of another Award or as a freestanding award.  The
terms and conditions of Dividend Equivalent Rights shall be specified in the
grant.  Dividend equivalents credited to the holder of a Dividend Equivalent
Right may be paid currently or may be deemed to be reinvested in additional
shares of Stock, which may thereafter accrue additional equivalents.  Any such
reinvestment shall be at Fair

                                       13
<PAGE>

Market Value on the date of reinvestment. Dividend Equivalent Rights may be
settled in cash or shares of Stock or a combination thereof, in a single
installment or installments. A Dividend Equivalent Right granted as a component
of another Award may provide that such Dividend Equivalent Right shall be
settled upon exercise, settlement, or payment of, or lapse of restrictions on,
such other award, and that such Dividend Equivalent Right shall expire or be
forfeited or annulled under the same conditions as such other award. A Dividend
Equivalent Right granted as a component of another Award may also contain terms
and conditions different from such other award.

     (b) Interest Equivalents.  Any Award under this Plan that is settled in
whole or in part in cash on a deferred basis may provide in the grant for
interest equivalents to be credited with respect to such cash payment.  Interest
equivalents may be compounded and shall be paid upon such terms and conditions
as may be specified by the grant.

     (c) Termination.  Except as may otherwise be provided by the Administrator
either in the Award agreement or, subject to Section 14 below, in writing after
the Award agreement is issued, a participant's rights in all Dividend Equivalent
Rights or interest equivalents shall automatically terminate upon the
participant's termination of employment (or cessation of business relationship)
with the Company and its Subsidiaries for any reason.

SECTION 11.  OTHER STOCK-BASED AWARDS
             ------------------------

     (a) Nature of Other Stock-Based Awards.  An Other Stock-Based Award
includes other Awards of Stock and other Awards that are valued in whole or in
part by reference to, or are otherwise based on, Stock, including without
limitation, convertible preferred stock, convertible debentures, exchangeable
securities and Awards valued by reference to book value or subsidiary
performance.  An Other Stock-Based Award may be granted to any participant
either along side or in addition to or in tandem with Stock Options, Restricted
Stock or Deferred Stock granted under the Plan and/or cash awards made outside
of the Plan.  Stock (including securities convertible into Stock) issued on a
bonus basis under this Section 11 may be issued for no cash consideration.
Stock (including securities convertible into Stock) purchased with a purchase
right awarded under this Section 11 shall be priced at least 25 percent of the
Fair Market Value of the Stock on the date of grant.  The grant of an Other
Stock-Based Award may be subject to restrictions and conditions as the
Administrator may determine at the time of grant, including conditions based on
continuing employment (or other business relationship) and/or achievement of
pre-established performance goals and objectives.  The grant of an Other Stock-
Based Award is contingent on the participant executing the Award agreement.  The
terms and conditions of each such agreement shall be determined by the
Administrator, and such terms and conditions may differ among individual Awards
and participants.

     (b) Rights as a Stockholder.  Until such time as an Other Stock-Based Award
is actually paid out in shares of Stock, a participant shall have no rights as a
holder of Stock.

                                       14
<PAGE>

     (c) Restrictions.  An Other Stock-Based Award may not be sold, assigned,
transferred, pledged or otherwise encumbered or disposed of except as
specifically provided herein or in the Award agreement.

     (d) Termination.  Except as may otherwise be provided by the Administrator
in the Award agreement or, subject to Section 14 below, in writing after the
Award agreement is issued, a participant's right in his Other Stock-Based Awards
that have not vested shall automatically terminate upon the participant's
termination of employment (or cessation of business relationship) with the
Company and its Subsidiaries for any reason.

SECTION 12.  TAX WITHHOLDING
             ---------------

     (a) Payment by Participant.  Each participant shall, no later than the date
as of which the value of an Award or of any Stock or other amounts received
thereunder first becomes includable in the gross income of the participant for
Federal income tax purposes, pay to the Company, or make arrangements
satisfactory to the Administrator regarding payment of, any Federal, state, or
local taxes of any kind required by law to be withheld with respect to such
income.  The Company and its Subsidiaries shall, to the extent permitted by law,
have the right to deduct any such taxes from any payment of any kind otherwise
due to the participant.  The Company's obligation to deliver stock certificates
to any participant is subject to and conditioned on tax obligations being
satisfied by the participant.

     (b) Payment in Stock.  Subject to approval by the Administrator, a
participant may elect to have the minimum tax withholding obligation satisfied,
in whole or in part, by (i) authorizing the Company to withhold from shares of
Stock to be issued pursuant to any Award a number of shares with an aggregate
Fair Market Value (as of the date the withholding is effected) that would
satisfy the minimum withholding amount due, or (ii) transferring to the Company
shares of Stock owned by the participant with an aggregate Fair Market Value (as
of the date the withholding is effected) that would satisfy the minimum
withholding amount due, or (iii) any combination of (i) and (ii).

SECTION 13.  TRANSFER, LEAVE OF ABSENCE, ETC.
             -------------------------------

     For purposes of the Plan, the following events shall not be deemed a
termination of employment:

     (a) a transfer to the employment of the Company from a Subsidiary or from
the Company to a Subsidiary, or from one Subsidiary to another Subsidiary; or

     (b) an approved leave of absence for military service or sickness, or for
any other purpose approved by the Company, if the employee's right to re-
employment is guaranteed either by a statute or by contract or under the written
policy pursuant to which the leave of absence was granted or if the
Administrator otherwise so provides in writing.

                                       15
<PAGE>

SECTION 14.  AMENDMENTS AND TERMINATION
             --------------------------

     The Administrator may, at any time, amend or discontinue the Plan and the
Administrator may, at any time, amend or cancel any outstanding Award for the
purpose of satisfying changes in law or for any other lawful purpose, but no
such action shall adversely affect rights under any outstanding Award without
the holder's written consent.  Except as provided in Section 3(b) or 3(c), in no
event may the Administrator exercise its discretion to reduce the exercise price
of outstanding Stock Options or effect repricing through cancellation and re-
grants.  If and to the extent determined by the Administrator to be required by
the Code to ensure that Incentive Stock Options granted under the Plan are
qualified under Section 422 of the Code or ensure that compensation earned under
Stock Options granted under the Plan qualifies as performance-based compensation
under Section 162(m) of the Code, if and to the extent intended to so qualify,
Plan amendments shall be subject to approval by the Company stockholders
entitled to vote at a meeting of stockholders.  Nothing in this Section 14 shall
limit the Board's authority to take any action permitted pursuant to Section
3(c).

SECTION 15.  STATUS OF PLAN
             --------------

     Unless the Administrator shall otherwise expressly determine in writing,
with respect to the portion of any Award which has not been exercised and any
payments in cash, Stock or other consideration not received by a participant, a
participant shall have no rights greater than those of a general creditor of the
Company.  In its sole discretion, the Administrator may authorize the creation
of trusts or other arrangements to meet the Company's obligations to deliver
Stock or make payments with respect to Awards hereunder, provided that the
existence of such trusts or other arrangements is consistent with the foregoing
sentence.

SECTION 16.  CHANGE OF CONTROL PROVISIONS
             ----------------------------

     (a) Upon the occurrence of a Change of Control as defined in this Section
16, all outstanding Options shall become immediately exercisable in full, and
all other Awards under the Plan shall become fully vested.

     (b) "Change of Control" shall mean the occurrence of any one of the
following events:

          (i) any "person," as such term is used in Sections 13(d) and 14(d) of
     the Act (other than the Company, any of its Subsidiaries, Mortimer B.
     Zuckerman, Edward H. Linde, any "affiliate" or "associate" (as such terms
     are defined in Rule 12b-2 under the Act) of Mortimer B. Zuckerman or Edward
     H. Linde, or any trustee, fiduciary or other person or entity holding
     securities under any employee benefit plan or trust of the Company or any
     of its Subsidiaries), together with all "affiliates" and "associates" (as
     such terms are defined in Rule 12b-2 under the Act) of such person, shall
     become the "beneficial owner" (as such term is defined in Rule 13d-3 under
     the Act), directly or indirectly, of securities of the Company representing
     25 percent or

                                       16
<PAGE>

     more of the combined voting power of the Company's then outstanding
     securities having the right to vote in an election of the Company's Board
     of Directors ("Voting Securities") (other than as a result of an
     acquisition of securities directly from the Company); provided that for
     purposes of determining the "beneficial ownership" (as such term is defined
     in Rule 13d-3 under the Act) of any "group" of which Mortimer B. Zuckerman,
     Edward H. Linde or any of their affiliates or associates is a member (each
     such entity or individual, a "Related Party"), there shall not be
     attributed to the "beneficial ownership" (as such term is defined in Rule
     13d-3 under the Act) of such group any shares beneficially owned by any
     Related Party; or

          (ii) persons who, as of the effective date of the Company's initial
     public offering of Stock, constitute the Company's Board of Directors (the
     "Incumbent Directors") cease for any reason, including, without limitation,
     as a result of a tender offer, proxy contest, merger or similar
     transaction, to constitute at least a majority of the Board, provided that
     any person becoming a director of the Company subsequent to such date shall
     be considered an Incumbent Director if such person's election was approved
     by or such person was nominated for election by either (A) a vote of at
     least two-thirds of the Incumbent Directors or (B) a vote of at least a
     majority of the Incumbent Directors who are members of a nominating
     committee comprised, in the majority, of Incumbent Directors; or

          (iii)  the stockholders of the Company shall approve (A) any
     consolidation or merger of the Company where the stockholders of the
     Company, immediately prior to the consolidation or merger, would not,
     immediately after the consolidation or merger, "beneficially own" (as such
     term is defined in Rule 13d-3 under the Act), directly or indirectly,
     shares representing in the aggregate 60 percent or more of the voting
     shares of the corporation issuing cash or securities in the consolidation
     or merger (or of its ultimate parent corporation, if any), (B) any sale,
     lease, exchange or other transfer to an unrelated party (in one transaction
     or a series of transactions contemplated or arranged by any party as a
     single plan) of all or substantially all of the assets of the Company or
     (C) any plan or proposal for the liquidation or dissolution of the Company.

     Notwithstanding the foregoing, a "Change of Control" shall not be deemed to
have occurred for purposes of the foregoing clause (i) solely as the result of
an acquisition of securities by the Company which, by reducing the number of
shares of Voting Securities outstanding, increases the proportionate number of
shares of Voting Securities beneficially owned by any person (as defined in the
foregoing clause (i)) to 25 percent or more of the combined voting power of all
then outstanding Voting Securities; provided, however, that if such person shall
thereafter become the beneficial owner of any additional shares of Voting
Securities (other than pursuant to a stock split, stock dividend, or similar
transaction or as a result of an acquisition of securities directly from the
Company), then a "Change of Control" shall be deemed to have occurred for
purposes of the foregoing clause (i).

                                       17
<PAGE>

SECTION 17.  GENERAL PROVISIONS
             ------------------

     (a) No Distribution; Compliance with Legal Requirements.  The Administrator
may require each person acquiring Stock pursuant to an Award to represent to and
agree with the Company in writing that such person is acquiring the shares
without a view to distribution thereof.

     No shares of Stock shall be issued pursuant to an Award until all
applicable securities law and other legal and stock exchange or similar
requirements have been satisfied.  The Administrator may require the placing of
such stop-orders and restrictive legends on certificates for Stock and Awards as
it deems appropriate.

     (b) Delivery of Stock Certificates.  Stock certificates to be delivered to
participants under this Plan shall be deemed delivered for all purposes when the
Company or a stock transfer agent of the Company shall have mailed such
certificates in the United States mail, addressed to the participant, at the
participant's last known address on file with the Company.

     (c) Other Compensation Arrangements; No Employment Rights.  Nothing
contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, including trusts, and such arrangements may be either
generally applicable or applicable only in specific cases.  The adoption of this
Plan and the grant of Awards shall not confer upon any employee any right to
continued employment with the Company or any Subsidiary and shall not interfere
in any way with the right of the Company or any Subsidiary to terminate the
employment of any of its employees at any time.

     (d) Trading Policy Restrictions.  Option exercises and other Awards under
the Plan shall be subject to such Company insider-trading-policy-related
restrictions, terms and conditions as may be established by the Administrator,
or in accordance with policies set by the Administrator, from time to time.

SECTION 18.  EFFECTIVE DATE OF PLAN

                      1997 STOCK OPTION AND INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT

     Pursuant to the Boston Properties, Inc. 1997 Stock Option and Incentive
Plan (the "Plan"), Boston Properties, Inc. (the "Company") hereby grants to
(the "Optionee"), a non-qualified stock option (the "Stock Option") to purchase
shares of Common Stock of the Company (the "Stock") at the price of $_____ per
share, subject to the terms of this Agreement and the Plan.  The Stock Option is
granted as of        the "Grant Date") and shall expire on        (the
"Expiration Date").  All terms used herein that are defined in the Plan shall
have the same meaning given them in the Plan.

     1. Timing of Exercise. Subject to Section 2 below and the discretion of
the Administrator to accelerate the vesting schedule hereunder, the Stock Option
shall become vested and exercisable with respect to the following whole number
of shares according to the timetable set forth below:

  Number of Years            Percentage of Shares          Cumulative Percentage
After Date of Grant     Becoming Available for Exercise          Available
-------------------     -------------------------------          ---------

Less than 3 years                     0%                             0%
At least 3 years                     33 1/3%                       33 1/3%
At least 4 years                     33 1/3%                       66 2/3%
5 or more years                      33 1/3%                       100%

     Notwithstanding the foregoing, the Stock Option shall become fully vested
and exercisable for the reasons stated in Sections 2(a), 2(b), 2(c) and 2(d)
below.   The Stock Option shall remain exercisable until the Expiration Date,
unless the Stock Option is terminated sooner as provided herein.

     2.  Termination of Employment.  If the Optionee ceases to be an employee of
the Company or Subsidiary, the period within which to exercise the Stock Option
may be subject to earlier termination as set forth below.

          (a) Termination Due to Death.  If the Optionee ceases to be an
     employee due to death, the Stock Option held by the Optionee shall become
     fully vested and exercisable and may thereafter be exercised by the
     Optionee's beneficiary or legal representative for a period of twelve (12)
     months from the date of death, or until the Expiration Date, if earlier.

          (b) Termination Due to Disability. If the Optionee ceases to be an
     employee as a result of incapacity due to physical or mental illness or
     disability which qualifies him to receive benefits under the Company's
     long-term disability plan, the Stock Option held by the Optionee shall
     become fully vested and exercisable and may thereafter be
<PAGE>

     exercised by the Optionee (or Optionee's legal representative if Optionee
     is incapacitated) for a period of twelve (12) months from the date of
     termination or until the Expiration Date, if earlier.

          (c) Termination by the Company without Cause or by Employee for Good
     Reason.  If the Optionee is terminated by the Company for reasons other
     than "Cause" (as defined herein), or if the Optionee terminates for Good
     Reason (as defined herein), the Stock Option held by the Optionee shall
     become fully vested and exercisable and may thereafter be exercised by the
     Optionee for a period of twelve (12) months from the date of termination or
     until the Expiration Date, if earlier.

          (d) Termination in Connection with a Change of  Control.  If the
     Optionee is terminated by the Company for reasons other than "Cause" (as
     defined herein) in connection with a Change of Control, or if the Optionee
     terminates employment for "Good Reason" (as defined herein), the Stock
     Option held by the Optionee shall become fully vested and exercisable and
     may thereafter be exercised by the Optionee for a period of twelve (12)
     months from the date of termination or until the Expiration Date, if
     earlier.  Notwithstanding the foregoing, nothing in this Section 2(d) shall
     limit the Board's authority to take any action permitted pursuant to
     Section 3(c) of the Plan.

          (e) Termination for Cause.  If the Optionee ceases to be an employee
     for Cause (as defined herein), the Stock Option held by the Optionee shall
     immediately terminate and be of no further force and effect.

          (f) Other Termination.  If the Optionee ceases to be an employee for
     any reason other than those stated in Sections 2(a), 2(b), 2(c), 2(d) or
     2(e) of this Agreement, the Stock Option held by the Optionee may be
     exercised to the extent exercisable at the time of his or her termination,
     for a period of three (3) months from the date of termination or until the
     Expiration Date, if earlier.  The remaining portion of the Stock Option
     held by the Optionee shall immediately terminate and be of no further force
     and effect.

For this purpose, neither a transfer of employment from the Company to a
Subsidiary (or from a Subsidiary to the Company) nor a leave of absence approved
in writing shall be deemed a "termination of employment."

     3.  Manner of Exercise.  Subject to Section 5 below, the Stock Option may
be exercised in whole or in part by giving written notice of exercise to the
Company specifying the number of shares of Stock to be purchased.  Payment of
the purchase price may be made by one or more of the following methods:

          (a) In cash, by certified or bank check or other instrument acceptable
     to the Administrator;

                                       2
<PAGE>

          (b)  In the form of shares of Stock that the Optionee has beneficially
     owned for more than six months and that are not then subject to
     restrictions under any Company plan.  Such surrendered shares shall be
     valued at Fair Market Value on the exercise date; or

          (c)  By the Optionee delivering to the Company a properly executed
     exercise notice together with irrevocable instructions to a broker to
     promptly deliver to the Company cash or a check payable and acceptable to
     the Company to pay the purchase price; provided that in the event the
     Optionee chooses to pay the purchase price as so provided, the Optionee and
     the broker shall comply with such procedures and enter into such agreements
     of indemnity and other agreements as the Administrator shall prescribe as a
     condition of such payment procedure.

     Payment instruments will be received subject to collection. The delivery of
certificates representing the shares of Stock to be purchased pursuant to the
exercise of a Stock Option will be contingent upon receipt from the Optionee (or
a purchaser acting in the Optionee's stead in accordance with the provisions
contained in the Plan or this Agreement) by the Company of the full purchase
price for such shares and any required withholding taxes, and the fulfillment of
any other requirements contained in the Plan, this Agreement or applicable
provisions of law.

     4.  Definitions.  For purposes of this Agreement:

          (a)   "Cause" shall mean:  (A) gross negligence or willful misconduct
     by Optionee in connection with the performance of his or her material
     duties as an employee of the Company or any Subsidiary; (B) a breach by
     Optionee of any of his or her material duties as an employee of the Company
     or any Subsidiary and the failure of Optionee to cure such breach within
     thirty (30) days after written notice thereof by the Company or any
     Subsidiary; (C) conduct by Optionee against the material best interests of
     the Company or any Subsidiary or a material act of common law fraud against
     the Company, any Subsidiary or the employees of either the Company or any
     Subsidiary; or (D) conviction of Optionee of a felony and such conviction
     has a material adverse effect on the interests or reputation of the Company
     or any Subsidiary.

          (b) "Good Reason" shall mean the voluntary termination of employment
     by Optionee following the occurrence of any of the following events: (A) a
     substantial adverse change, not consented to by Optionee, in the nature or
     scope of Optionee's responsibilities, authorities, powers, functions or
     duties from the responsibilities, authorities, powers, functions or duties
     exercised by Optionee immediately prior to a Change of Control; (B) an
     involuntary reduction in Optionee's annual base salary except for across-
     the-board salary reduction similarly affecting all or substantially all
     employees; (C) the relocation of the company's offices at which Optionee is
     principally employed or the relocation of the offices of Optionee's primary
     workgroup to a location more than thirty (30) miles from such offices, or
     the requirement by the Company for Optionee to be based anywhere other than
     the Company's offices at such location on an extended basis,
     except for required travel of the Company's business to an extent
     substantially consistent

                                       3
<PAGE>

     with Optionee's business travel obligations; or (D) the failure by the
     Company to pay the Optionee any portion of his compensation within fifteen
     (15) days of the date such compensation is due without the prior written
     consent of the Optionee.

     5.  Trading Policy Restrictions.  Option exercises shall be subject to such
Company trading-policy-related restrictions, terms and conditions as may be
established by the Administrator, or in accordance with policies set by the
Administrator, from time to time.

     6.  The Stock Option Transferable in Limited Circumstances.  Subject to
prior written notification to the Company by the Optionee, the Stock Option may
be transferred to a family member, a trust for the benefit of one or more family
members or a partnership in which family members are the only partners;
provided, however, that the transferee agrees in writing with the Company to be
bound by the terms of this Agreement and the Plan.  Except as permitted in the
preceding sentence, the Stock Option is not transferable otherwise than by will
or by the laws of descent and distribution, and shall be exercisable during the
Optionee's lifetime only by the Optionee.

     7.  Stock Option Shares.  The shares to be issued under the Plan are shares
of the Common Stock of the Company as constituted as of the date of this
Agreement, subject to adjustments pursuant to Section 3 of the Plan.

     8.  Rights as a Stockholder.  The Optionee shall have the rights of a
stockholder only as to shares of Stock acquired upon exercise of the Stock
Option and not as to any shares of Stock covered by unexercised Stock Options.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such shares are acquired.

     9.  Tax Withholding.   No later than the date on which part or all of the
value of any shares of Stock received under the Plan first becomes includible in
the Optionee's gross income for Federal income tax purposes, the Optionee shall
make arrangements with the Administrator in accordance with Section 12 of the
Plan regarding the payment of any federal, state or local taxes required to be
withheld with respect to such income.  Such payment may be either in cash or in
Stock, subject to approval by the Administrator.

     10.  Tax Status.  The Stock Option is not intended to qualify as an
incentive stock option under Section 422 of the Internal Revenue Code of 1986,
as amended.

     11.  The Plan.  The Stock Option is subject in all respects to the terms,
conditions, limitations and definitions contained in the Plan.  In the event of
any discrepancy or inconsistency between this Agreement and the Plan, the terms
and conditions of the Plan shall control.

     12.  No Obligation to Exercise Stock Option.  The grant and acceptance of
the Stock Option imposes no obligation on the Optionee to exercise it.

                                       4
<PAGE>

     13.  No Obligation to Continue Employment.  Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to
continue the Optionee in employment and neither the Plan nor this Agreement
shall interfere in any way with the right of the Company or any Subsidiary to
terminate the employment of the Optionee at any time.

     14.  Notices.  Notices hereunder shall be mailed or delivered to the
Company at its principal place of business and shall be mailed or delivered to
the Optionee at the address on file with the Company or, in either case, at such
other address as one party may subsequently furnish to the other party in
writing.

     15.  Purchase Only for Investment.  To insure the Company's compliance with
the Securities Act of 1933, as amended, the Optionee agrees for himself or
herself, the Optionee's legal representatives and estate, or other persons who
acquire the right to exercise the Stock Option upon his or her death, that
shares will be purchased in the exercise of the Stock Option for investment
purposes only and not with a view to their distribution, as that term is used in
the Securities Act of 1933, as amended, unless in the opinion of counsel to the
Company such distribution is in compliance with or exempt from the registration
and prospectus requirements of that Act.

     16.  Governing Law.  This Agreement and the Stock Option shall be governed
by, and construed in accordance with, the laws of the State of Delaware, applied
without regard to conflict of law principles.

     17.  Beneficiary Designation.  The Optionee hereby designates the following
person(s) as the Optionee's beneficiary(ies) to whom shall be transferred any
rights under the Stock Option which survive the Optionee's death.  If the
Optionee names more than one primary beneficiary and one or more of such primary
beneficiaries die, the deceased primary beneficiary's interest will be
apportioned among any surviving primary beneficiaries before any contingent
beneficiary receives any amount, unless the Optionee indicates otherwise in a
signed and dated additional page.  The same rule shall apply within the category
of contingent beneficiaries.  Unless the Optionee has specified otherwise
herein, any rights which survive the Optionee's death will be divided equally
among the Optionee's primary beneficiaries or contingent beneficiaries, as the
case may be.  If no beneficiary survives the Optionee or there is no effective
beneficiary designation, the Optionee's estate shall be deemed to be his or her
beneficiary.

                             BOSTON PROPERTIES, INC.
                      1997 STOCK OPTION AND INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT

     Pursuant to the Boston Properties, Inc. 1997 Stock Option and Incentive
Plan (the "Plan"), Boston Properties, Inc. (the "Company") hereby grants to
(the "Optionee"), a non-qualified stock option (the "Stock Option") to purchase
shares of Common Stock of the Company (the "Stock") at the price of $_____ per
share, subject to the terms of this Agreement and the Plan.  The Stock Option is
granted as of        the "Grant Date") and shall expire on        (the
"Expiration Date").  All terms used herein that are defined in the Plan shall
have the same meaning given them in the Plan.

      1. Timing of Exercise. Subject to Section 2 below and the discretion of
the Administrator to accelerate the vesting schedule hereunder, the Stock Option
shall become vested and exercisable with respect to the following whole number
of shares according to the timetable set forth below:

 Number of Years            Percentage of Shares           Cumulative Percentage
After Date of Grant     Becoming Available for Exercise          Available
-------------------     -------------------------------    ---------------------

Less than 3 years                    0%                             0%
At least 3 years                    33 1/3%                        33 1/3%
At least 4 years                    33 1/3%                        66 2/3%
5 or more years                     33 1/3%                        100%

     Notwithstanding the foregoing, the Stock Option shall become fully vested
and exercisable for the reasons stated in Sections 2(a), 2(b), 2(c) and 2(d)
below.   The Stock Option shall remain exercisable until the Expiration Date,
unless the Stock Option is terminated sooner as provided herein.

     2.  Termination of Employment.  If the Optionee ceases to be an employee of
the Company or Subsidiary, the period within which to exercise the Stock Option
may be subject to earlier termination as set forth below.

          (a) Termination Due to Death.  If the Optionee ceases to be an
     employee due to death, the Stock Option held by the Optionee shall become
     fully vested and exercisable and may thereafter be exercised by the
     Optionee's beneficiary or legal representative for a period of twelve (12)
     months from the date of death, or until the Expiration Date, if earlier.

           (b) Termination Due to Disability. If the Optionee ceases to be an
     employee as a result of incapacity due to physical or mental illness or
     disability which qualifies him to receive benefits under the Company's
     long-term disability plan, the Stock Option held by the Optionee shall
     become fully vested and exercisable and may thereafter be
<PAGE>

     exercised by the Optionee (or Optionee's legal representative if Optionee
     is incapacitated) for a period of twelve (12) months from the date of
     termination or until the Expiration Date, if earlier.

          (c) Termination by the Company without Cause or by Employee for Good
     Reason.  If the Optionee is terminated by the Company for reasons other
     than "Cause" (as defined herein), or if the Optionee terminates for Good
     Reason (as defined in the Employment Agreement dated June 14, 1997, between
     the Company and the Optionee), the Stock Option held by the Optionee shall
     become fully vested and exercisable and may thereafter be exercised by the
     Optionee for a period of twelve (12) months from the date of termination or
     until the Expiration Date, if earlier

          (d) Termination in Connection with a Change of  Control.  If the
     Optionee is terminated by the Company for reasons other than "Cause" (as
     defined herein) in connection with a Change of Control, or if the Optionee
     terminates employment for "Good Reason" (as defined herein), the Stock
     Option held by the Optionee shall become fully vested and exercisable and
     may thereafter be exercised by the Optionee for a period of twelve (12)
     months from the date of termination or until the Expiration Date, if
     earlier.  Notwithstanding the foregoing, nothing in this Section 2(d) shall
     limit the Board's authority to take any action permitted pursuant to
     Section 3(c) of the Plan.

          (e) Termination for Cause.  If the Optionee ceases to be an employee
     for Cause (as defined herein), the Stock Option held by the Optionee shall
     immediately terminate and be of no further force and effect.

          (f) Other Termination.  If the Optionee ceases to be an employee for
     any reason other than those stated in Sections 2(a), 2(b), 2(c), 2(d) or
     2(e) of this Agreement, the Stock Option held by the Optionee may be
     exercised to the extent exercisable at the time of his or her termination,
     for a period of three (3) months from the date of termination or until the
     Expiration Date, if earlier.  The remaining portion of the Stock Option
     held by the Optionee shall immediately terminate and be of no further force
     and effect.

For this purpose, neither a transfer of employment from the Company to a
Subsidiary (or from a Subsidiary to the Company) nor a leave of absence approved
in writing shall be deemed a "termination of employment."

     3.  Manner of Exercise.  Subject to Section 5 below, the Stock Option may
be exercised in whole or in part by giving written notice of exercise to the
Company specifying the number of shares of Stock to be purchased.  Payment of
the purchase price may be made by one or more of the following methods:

          (a) In cash, by certified or bank check or other instrument acceptable
     to the Administrator;

                                       2
<PAGE>

          (b)  In the form of shares of Stock that the Optionee has beneficially
     owned for more than six months and that are not then subject to
     restrictions under any Company plan.  Such surrendered shares shall be
     valued at Fair Market Value on the exercise date; or

          (c)  By the Optionee delivering to the Company a properly executed
     exercise notice together with irrevocable instructions to a broker to
     promptly deliver to the Company cash or a check payable and acceptable to
     the Company to pay the purchase price; provided that in the event the
     Optionee chooses to pay the purchase price as so provided, the Optionee and
     the broker shall comply with such procedures and enter into such agreements
     of indemnity and other agreements as the Administrator shall prescribe as a
     condition of such payment procedure.

     Payment instruments will be received subject to collection.  The delivery
of certificates representing the shares of Stock to be purchased pursuant to the
exercise of a Stock Option will be contingent upon receipt from the Optionee (or
a purchaser acting in the Optionee's stead in accordance with the provisions
contained in the Plan or this Agreement) by the Company of the full purchase
price for such shares and any required withholding taxes, and the fulfillment of
any other requirements contained in the Plan, this Agreement or applicable
provisions of law.

     4.  Definitions.  For purposes of this Agreement:

          (a)   "Cause" shall mean:  (A) gross negligence or willful misconduct
     by Optionee in connection with the performance of his or her material
     duties as an employee of the Company or any Subsidiary; (B) a breach by
     Optionee of any of his or her material duties as an employee of the Company
     or any Subsidiary and the failure of Optionee to cure such breach within
     thirty (30) days after written notice thereof by the Company or any
     Subsidiary; (C) conduct by Optionee against the material best interests of
     the Company or any Subsidiary or a material act of common law fraud against
     the Company, any Subsidiary or the employees of either the Company or any
     Subsidiary; or (D) conviction of Optionee of a felony and such conviction
     has a material adverse effect on the interests or reputation of the Company
     or any Subsidiary.

          (b) "Good Reason" shall mean the voluntary termination of employment
     by Optionee following the occurrence of any of the following events: (A) a
     substantial adverse change, not consented to by Optionee, in the nature or
     scope of Optionee's responsibilities, authorities, powers, functions or
     duties from the responsibilities, authorities, powers, functions or duties
     exercised by Optionee immediately prior to a Change of Control; (B) an
     involuntary reduction in Optionee's annual base salary except for across-
     the-board salary reduction similarly affecting all or substantially all
     employees; (C) the relocation of the company's offices at which Optionee is
     principally employed or the relocation of the offices of Optionee's primary
     workgroup to a location more than thirty (30) miles from such offices, or
     the requirement by the Company for Optionee to be based anywhere other than
     the Company's offices at such location on an extended basis,

                                       3
<PAGE>

     except for required travel of the Company's business to an extent
     substantially consistent with Optionee's business travel obligations; or
     (D) the failure by the Company to pay the Optionee any portion of his
     compensation within fifteen (15) days of the date such compensation is due
     without the prior written consent of the Optionee.

     5.  Trading Policy Restrictions.  Option exercises shall be subject to such
Company trading-policy-related restrictions, terms and conditions as may be
established by the Administrator, or in accordance with policies set by the
Administrator, from time to time.

     6.  The Stock Option Transferable in Limited Circumstances.  Subject to
prior written notification to the Company by the Optionee, the Stock Option may
be transferred to a family member, a trust for the benefit of one or more family
members or a partnership in which family members are the only partners;
provided, however, that the transferee agrees in writing with the Company to be
bound by the terms of this Agreement and the Plan.  Except as permitted in the
preceding sentence, the Stock Option is not transferable otherwise than by will
or by the laws of descent and distribution, and shall be exercisable during the
Optionee's lifetime only by the Optionee.

     7.  Stock Option Shares.  The shares to be issued under the Plan are shares
of the Common Stock of the Company as constituted as of the date of this
Agreement, subject to adjustments pursuant to Section 3 of the Plan.

     8.  Rights as a Stockholder.  The Optionee shall have the rights of a
stockholder only as to shares of Stock acquired upon exercise of the Stock
Option and not as to any shares of Stock covered by unexercised Stock Options.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such shares are acquired.

     9.  Tax Withholding.   No later than the date on which part or all of the
value of any shares of Stock received under the Plan first becomes includible in
the Optionee's gross income for Federal income tax purposes, the Optionee shall
make arrangements with the Administrator in accordance with Section 12 of the
Plan regarding the payment of any federal, state or local taxes required to be
withheld with respect to such income.  Such payment may be either in cash or in
Stock, subject to approval by the Administrator.

     10.  Tax Status.  The Stock Option is not intended to qualify as an
incentive stock option under Section 422 of the Internal Revenue Code of 1986,
as amended.

     11.  The Plan.  The Stock Option is subject in all respects to the terms,
conditions, limitations and definitions contained in the Plan.  In the event of
any discrepancy or inconsistency between this Agreement and the Plan, the terms
and conditions of the Plan shall control.

     12.  No Obligation to Exercise Stock Option.  The grant and acceptance of
the Stock Option imposes no obligation on the Optionee to exercise it.

                                       4
<PAGE>

     13.  No Obligation to Continue Employment.  Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to
continue the Optionee in employment and neither the Plan nor this Agreement
shall interfere in any way with the right of the Company or any Subsidiary to
terminate the employment of the Optionee at any time.

     14.  Notices.  Notices hereunder shall be mailed or delivered to the
Company at its principal place of business and shall be mailed or delivered to
the Optionee at the address on file with the Company or, in either case, at such
other address as one party may subsequently furnish to the other party in
writing.

     15.  Purchase Only for Investment.  To insure the Company's compliance with
the Securities Act of 1933, as amended, the Optionee agrees for himself or
herself, the Optionee's legal representatives and estate, or other persons who
acquire the right to exercise the Stock Option upon his or her death, that
shares will be purchased in the exercise of the Stock Option for investment
purposes only and not with a view to their distribution, as that term is used in
the Securities Act of 1933, as amended, unless in the opinion of counsel to the
Company such distribution is in compliance with or exempt from the registration
and prospectus requirements of that Act.

     16.  Governing Law.  This Agreement and the Stock Option shall be governed
by, and construed in accordance with, the laws of the State of Delaware, applied
without regard to conflict of law principles.

     17.  Beneficiary Designation.  The Optionee hereby designates the following
person(s) as the Optionee's beneficiary(ies) to whom shall be transferred any
rights under the Stock Option which survive the Optionee's death.  If the
Optionee names more than one primary beneficiary and one or more of such primary
beneficiaries die, the deceased primary beneficiary's interest will be
apportioned among any surviving primary beneficiaries before any contingent
beneficiary receives any amount, unless the Optionee indicates otherwise in a
signed and dated additional page.  The same rule shall apply within the category
of contingent beneficiaries.  Unless the Optionee has specified otherwise
herein, any rights which survive the Optionee's death will be divided equally
among the Optionee's primary beneficiaries or contingent beneficiaries, as the
case may be.  If no beneficiary survives the Optionee or there is no effective
beneficiary designation, the Optionee's estate shall be deemed to be his or her
beneficiary.

                      1997 STOCK OPTION AND INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT

      Pursuant to the Boston Properties, Inc. 1997 Stock Option and Incentive
Plan (the "Plan"), Boston Properties, Inc. (the "Company") hereby grants to (the
"Optionee"), a non-qualified stock option (the "Stock Option") to purchase
shares of Common Stock of the Company (the "Stock") at the price of $ per share,
subject to the terms of this Agreement and the Plan. The Stock Option is granted
as of (the "Grant Date") and shall expire on (the "Expiration Date"). All terms
used herein that are defined in the Plan shall have the same meaning given them
in the Plan.

      1. Timing of Exercise. Subject to Section 2 below and the discretion of
the Administrator to accelerate the vesting schedule hereunder, the Stock Option
shall become vested and exercisable with respect to the following whole number
of shares according to the timetable set forth below:

  Number of Years            Percentage of Shares          Cumulative Percentage
After Date of Grant     Becoming Available for Exercise          Available

Less than 1 year                       0%                          0%
At least 1 year                       33 1/3%                     33 1/3%
At least 2 years                      33 1/3%                     66 2/3%
3 or more years                       33 1/3%                      100%

     Notwithstanding the foregoing, the Stock Option shall become fully vested
and exercisable when the Optionee attains age 65, dies or becomes incapacitated
(as defined in Section 2(b) below) or upon a Change in Control (as defined in
the Plan) of the Company.  The Stock Option shall remain exercisable until the
Expiration Date, unless the Stock Option is terminated sooner as provided
herein.

     2.  Termination of Employment.  If the Optionee ceases to be an employee of
the Company or Subsidiary, the period within which to exercise the Stock Option
may be subject to earlier termination as set forth below.

          (a) Termination Due to Death.  If the Optionee ceases to be an
     employee due to death, the Stock Option held by the Optionee shall become
     fully vested and exercisable and may thereafter be exercised by the
     Optionee's beneficiary or legal representative for a period of twelve (12)
     months from the date of death, or until the Expiration Date, if earlier.

          (b) Termination Due to Disability. If the Optionee ceases to be an
     employee as a result of incapacity due to physical or mental illness or
     disability which qualifies him or her to receive benefits under the
     Company's long-term disability plan, the Stock
<PAGE>

     Option held by the Optionee shall become fully vested and exercisable and
     may thereafter be exercised by the Optionee (or Optionee's legal
     representative if Optionee is incapacitated) for a period of twelve (12)
     months from the date of termination or until the Expiration Date, if
     earlier.

          (c) Termination in Connection with Retirement.  If the Optionee's
     employment terminates by reason of Retirement (as defined in the Plan), the
     Stock Option held by the Optionee may be exercised to the extent
     exercisable at the time of his or her Retirement, for a period of twenty-
     four (24) months from the date of Retirement or until the Expiration Date,
     if earlier.

          (d) Termination for Cause.  If the Optionee ceases to be an employee
     for Cause (as defined herein), the Stock Option held by the Optionee shall
     immediately terminate and be of no further force and effect.

          (e) Other Termination.  If the Optionee ceases to be an employee for
     any reason other than those stated in Sections 2(a), 2(b), 2(c) or 2(d) of
     this Agreement, the Stock Option held by the Optionee may be exercised to
     the extent exercisable at the time of his or her termination, for a period
     of three (3) months from the date of termination or until the Expiration
     Date, if earlier.  The remaining portion of the Stock Option held by the
     Optionee shall immediately terminate and be of no further force and effect.

For this purpose, neither a transfer of employment from the Company to a
Subsidiary (or from a Subsidiary to the Company) nor a leave of absence approved
in writing shall be deemed a "termination of employment."

     3.  Manner of Exercise.  Subject to Section 5 below, the Stock Option may
be exercised in whole or in part by giving written notice of exercise to the
Company specifying the number of shares of Stock to be purchased.  Payment of
the purchase price may be made by one or more of the following methods:

          (a) In cash, by certified or bank check or other instrument acceptable
     to the Administrator;

          (b)  In the form of shares of Stock that the Optionee has beneficially
     owned for more than six months and that are not then subject to
     restrictions under any Company plan.  Such surrendered shares shall be
     valued at Fair Market Value on the exercise date; or

          (c)  By the Optionee delivering to the Company a properly executed
     exercise notice together with irrevocable instructions to a broker to
     promptly deliver to the Company cash or a check payable and acceptable to
     the Company to pay the purchase price; provided that in the event the
     Optionee chooses to pay the purchase price as so provided, the Optionee and
     the broker shall comply with such procedures and enter into such agreements
     of indemnity and other agreements as the Administrator shall prescribe as a
     condition of such payment procedure.

     Payment instruments will be received subject to collection.  The delivery
of certificates
<PAGE>

representing the shares of Stock to be purchased pursuant to the exercise of a
Stock Option will be contingent upon receipt from the Optionee (or a purchaser
acting in the Optionee's stead in accordance with the provisions contained in
the Plan or this Agreement) by the Company of the full purchase price for such
shares and any required withholding taxes, and the fulfillment of any other
requirements contained in the Plan, this Agreement or applicable provisions of
law.

     4.  Definitions.  For purposes of this Agreement:

          "Cause" shall mean:  (A) gross negligence or willful misconduct by
     Optionee in connection with the performance of his or her material duties
     as an employee of the Company or any Subsidiary; (B) a breach by Optionee
     of any of his or her material duties as an employee of the Company or any
     Subsidiary and the failure of Optionee to cure such breach within thirty
     (30) days after written notice thereof by the Company or any Subsidiary;
     (C) conduct by Optionee against the material best interests of the Company
     or any Subsidiary or a material act of common law fraud against the
     Company, any Subsidiary or the employees of either the Company or any
     Subsidiary; or (D) conviction of Optionee of a felony and such conviction
     has a material adverse effect on the interests or reputation of the Company
     or any Subsidiary.

     5.  Trading Policy Restrictions.  Option exercises shall be subject to such
Company trading-policy-related restrictions, terms and conditions as may be
established by the Administrator, or in accordance with policies set by the
Administrator, from time to time.

     6.  Non-Transferability of Stock Option. The Stock Option is not
transferable otherwise than by will or by the laws of descent and distribution,
and shall be exercisable during the Optionee's lifetime only by the Optionee.

     7.  Stock Option Shares.  The shares to be issued under the Plan are shares
of the Common Stock of the Company as constituted as of the date of this
Agreement, subject to adjustments pursuant to Section 3 of the Plan.

     8.  Rights as a Stockholder.  The Optionee shall have the rights of a
stockholder only as to shares of Stock acquired upon exercise of the Stock
Option and not as to any shares of Stock covered by unexercised Stock Options.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such shares are acquired.

     9.  Tax Withholding.   No later than the date on which part or all of the
value of any shares of Stock received under the Plan first becomes includible in
the Optionee's gross income for Federal income tax purposes, the Optionee shall
make arrangements with the Administrator in accordance with Section 12 of the
Plan regarding the payment of any federal, state or local taxes required to be
withheld with respect to such income.  Such payment may be either in cash
<PAGE>

or in Stock, subject to approval by the Administrator.

     10.  Tax Status.  The Stock Option is not intended to qualify as an
incentive stock option under Section 422 of the Internal Revenue Code of 1986,
as amended.

     11.  The Plan.  The Stock Option is subject in all respects to the terms,
conditions, limitations and definitions contained in the Plan.  In the event of
any discrepancy or inconsistency between this Agreement and the Plan, the terms
and conditions of the Plan shall control.

     12.  No Obligation to Exercise Stock Option.  The grant and acceptance of
the Stock Option imposes no obligation on the Optionee to exercise it.

     13.  No Obligation to Continue Employment.  Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to
continue the Optionee in employment and neither the Plan nor this Agreement
shall interfere in any way with the right of the Company or any Subsidiary to
terminate the employment of the Optionee at any time.

     14.  Notices.  Notices hereunder shall be mailed or delivered to the
Company at its principal place of business and shall be mailed or delivered to
the Optionee at the address on file with the Company or, in either case, at such
other address as one party may subsequently furnish to the other party in
writing.

     15.  Purchase Only for Investment.  To insure the Company's compliance with
the Securities Act of 1933, as amended, the Optionee agrees for himself or
herself, the Optionee's legal representatives and estate, or other persons who
acquire the right to exercise the Stock Option upon his or her death, that
shares will be purchased in the exercise of the Stock Option for investment
purposes only and not with a view to their distribution, as that term is used in
the Securities Act of 1933, as amended, unless in the opinion of counsel to the
Company such distribution is in compliance with or exempt from the registration
and prospectus requirements of that Act.

     16.  Governing Law.  This Agreement and the Stock Option shall be governed
by, and construed in accordance with, the laws of the State of Delaware, applied
without regard to conflict of law principles.

     17.  Beneficiary Designation.  The Optionee hereby designates the following
person(s) as the Optionee's beneficiary(ies) to whom shall be transferred any
rights under the Stock Option which survive the Optionee's death.  If the
Optionee names more than one primary beneficiary and one or more of such primary
beneficiaries die, the deceased primary beneficiary's interest will be
apportioned among any surviving primary beneficiaries before any contingent
beneficiary receives any amount, unless the Optionee indicates otherwise in a
signed and dated additional page.  The same rule shall apply within the category
of contingent beneficiaries.  Unless the Optionee has specified otherwise
herein, any rights which survive the Optionee's death will be divided equally
among the Optionee's primary beneficiaries or contingent beneficiaries, as the
case may be.  If no beneficiary survives the Optionee or there is no effective
beneficiary designation, the Optionee's estate shall be deemed to be his or her
beneficiary.

Plan (the "Plan"), Boston Properties, Inc. (the "Company") hereby grants to (the

used herein that are defined in the Plan shall have the same meaning given them

At least 1 year                     33 1/3%                         33 1/3%

3 or more years                     33 1/3%                          100%

     Notwithstanding the foregoing, the Stock Option shall become fully vested
and exercisable when the Optionee attains age 65, dies or becomes incapacitated
(as defined in Section 2(b) below) or upon a Change in Control (as defined in
the Plan) of the Company.  The Stock Option shall remain exercisable until the
Expiration Date, unless the Stock Option is terminated sooner as provided
herein.

     2.  Termination of Employment.  If the Optionee ceases to be an employee of
the Company or Subsidiary, the period within which to exercise the Stock Option
may be subject to earlier termination as set forth below.

          (a) Termination Due to Death.  If the Optionee ceases to be an
     employee due to death, the Stock Option held by the Optionee shall become
     fully vested and exercisable and may thereafter be exercised by the
     Optionee's beneficiary or legal representative for a period of twelve (12)
     months from the date of death, or until the Expiration Date, if earlier.

          (b) Termination Due to Disability.  If the Optionee ceases to be an
     employee as a result of incapacity due to physical or mental illness or
     disability which qualifies

                                       1
<PAGE>

     him or her to receive benefits under the Company's long-term disability
     plan, the Stock Option held by the Optionee shall become fully vested and
     exercisable and may thereafter be exercised by the Optionee (or Optionee's
     legal representative if Optionee is incapacitated) for a period of twelve
     (12) months from the date of termination or until the Expiration Date, if
     earlier.

          (c) Termination in Connection with Retirement.  If the Optionee's
     employment terminates by reason of Retirement (as defined in the Plan), the
     Stock Option held by the Optionee may be exercised to the extent
     exercisable at the time of his or her Retirement, for a period of twenty-
     four (24) months from the date of Retirement or until the Expiration Date,
     if earlier.

          (d) Termination for Cause.  If the Optionee ceases to be an employee
     for Cause (as defined herein), the Stock Option held by the Optionee shall
     immediately terminate and be of no further force and effect.

          (e) Other Termination.  If the Optionee ceases to be an employee for
     any reason other than those stated in Sections 2(a), 2(b), 2(c) or 2(d) of
     this Agreement, the Stock Option held by the Optionee may be exercised to
     the extent exercisable at the time of his or her termination, for a period
     of three (3) months from the date of termination or until the Expiration
     Date, if earlier.  The remaining portion of the Stock Option held by the
     Optionee shall immediately terminate and be of no further force and effect.

For this purpose, neither a transfer of employment from the Company to a
Subsidiary (or from a Subsidiary to the Company) nor a leave of absence approved
in writing shall be deemed a "termination of employment."

     3.  Manner of Exercise.  Subject to Section 5 below, the Stock Option may
be exercised in whole or in part by giving written notice of exercise to the
Company specifying the number of shares of Stock to be purchased.  Payment of
the purchase price may be made by one or more of the following methods:

          (a) In cash, by certified or bank check or other instrument acceptable
     to the Administrator;

          (b)  In the form of shares of Stock that the Optionee has beneficially
     owned for more than six months and that are not then subject to
     restrictions under any Company plan.  Such surrendered shares shall be
     valued at Fair Market Value on the exercise date; or

          (c)  By the Optionee delivering to the Company a properly executed
     exercise notice together with irrevocable instructions to a broker to
     promptly deliver to the Company cash or a check payable and acceptable to
     the Company to pay the purchase price; provided that in the event the
     Optionee chooses to pay the purchase price as so provided, the Optionee and
     the broker shall comply with such procedures and enter into such agreements
     of indemnity and other agreements as the Administrator shall prescribe

                                       2
<PAGE>

     as a condition of such payment procedure.

     Payment instruments will be received subject to collection.  The delivery
of certificates representing the shares of Stock to be purchased pursuant to the
exercise of a Stock Option will be contingent upon receipt from the Optionee (or
a purchaser acting in the Optionee's stead in accordance with the provisions
contained in the Plan or this Agreement) by the Company of the full purchase
price for such shares and any required withholding taxes, and the fulfillment of
any other requirements contained in the Plan, this Agreement or applicable
provisions of law.

     4.  Definitions.  For purposes of this Agreement:

          "Cause" shall mean:  (A) gross negligence or willful misconduct by
     Optionee in connection with the performance of his or her material duties
     as an employee of the Company or any Subsidiary; (B) a breach by Optionee
     of any of his or her material duties as an employee of the Company or any
     Subsidiary and the failure of Optionee to cure such breach within thirty
     (30) days after written notice thereof by the Company or any Subsidiary;
     (C) conduct by Optionee against the material best interests of the Company
     or any Subsidiary or a material act of common law fraud against the
     Company, any Subsidiary or the employees of either the Company or any
     Subsidiary; or (D) conviction of Optionee of a felony and such conviction
     has a material adverse effect on the interests or reputation of the Company
     or any Subsidiary.

     5.  Trading Policy Restrictions.  Option exercises shall be subject to such
Company trading-policy-related restrictions, terms and conditions as may be
established by the Administrator, or in accordance with policies set by the
Administrator, from time to time.

     6.  The Stock Option Transferable in Limited Circumstances.  Subject to
prior written notification to the Company by the Optionee, the Stock Option may
be transferred to a family member, a trust for the benefit of one or more family
members or a partnership in which family members are the only partners;
provided, however, that the transferee agrees in writing with the Company to be
bound by the terms of this Agreement and the Plan.  Except as permitted in the
preceding sentence, the Stock Option is not transferable otherwise than by will
or by the laws of descent and distribution, and shall be exercisable during the
Optionee's lifetime only by the Optionee.

     7.  Stock Option Shares.  The shares to be issued under the Plan are shares
of the Common Stock of the Company as constituted as of the date of this
Agreement, subject to adjustments pursuant to Section 3 of the Plan.

     8.  Rights as a Stockholder.  The Optionee shall have the rights of a
stockholder only as to shares of Stock acquired upon exercise of the Stock
Option and not as to any shares of Stock covered by unexercised Stock Options.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such shares are acquired.

     9.  Tax Withholding.   No later than the date on which part or all of the
value of any shares of Stock received under the Plan first becomes includible in
the Optionee's gross income for Federal income tax purposes, the Optionee shall
make arrangements with the Administrator in accordance with Section 12 of the
Plan regarding the payment of any federal, state or local taxes required to be
withheld with respect to such income.  Such payment may be either in cash or in
Stock, subject to approval by the Administrator.

     10.  Tax Status.  The Stock Option is not intended to qualify as an

as amended.

     11.  The Plan.  The Stock Option is subject in all respects to the terms,
conditions, limitations and definitions contained in the Plan.  In the event of
any discrepancy or inconsistency between this Agreement and the Plan, the terms
and conditions of the Plan shall control.

     12.  No Obligation to Exercise Stock Option.  The grant and acceptance of
the Stock Option imposes no obligation on the Optionee to exercise it.

     13.  No Obligation to Continue Employment.  Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to
continue the Optionee in employment and neither the Plan nor this Agreement

terminate the employment of the Optionee at any time.

     14.  Notices.  Notices hereunder shall be mailed or delivered to the
Company at its principal place of business and shall be mailed or delivered to
the Optionee at the address on file with the Company or, in either case, at such
other address as one party may subsequently furnish to the other party in
writing.

     15.  Purchase Only for Investment.  To insure the Company's compliance with
the Securities Act of 1933, as amended, the Optionee agrees for himself or
herself, the Optionee's legal representatives and estate, or other persons who
acquire the right to exercise the Stock Option upon his or her death, that
shares will be purchased in the exercise of the Stock Option for investment
purposes only and not with a view to their distribution, as that term is used in
the Securities Act of 1933, as amended, unless in the opinion of counsel to the
Company such distribution is in compliance with or exempt from the registration
and prospectus requirements of that Act.

     16.  Governing Law.  This Agreement and the Stock Option shall be governed
by, and construed in accordance with, the laws of the State of Delaware, applied
without regard to conflict of law principles.

     17.  Beneficiary Designation.  The Optionee hereby designates the following
person(s) as the Optionee's beneficiary(ies) to whom shall be transferred any
rights under the Stock Option which survive the Optionee's death.  If the
Optionee names more than one primary beneficiary and one or more of such primary
beneficiaries die, the deceased primary beneficiary's interest will be
apportioned among any surviving primary beneficiaries before any contingent
beneficiary receives any amount, unless the Optionee indicates otherwise in a
signed and dated additional page.  The same rule shall apply within the category
of contingent beneficiaries.  Unless the Optionee has specified otherwise
herein, any rights which survive the Optionee's death will be divided equally
among the Optionee's primary beneficiaries or contingent beneficiaries, as the
case may be.  If no beneficiary survives the Optionee or there is no effective
beneficiary

designation, the Optionee's estate shall be deemed to be his or her beneficiary.

                             BOSTON PROPERTIES, INC.
                      1997 STOCK OPTION AND INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT

     Pursuant to the Boston Properties, Inc. 1997 Stock Option and Incentive
Plan (the "Plan"), Boston Properties, Inc. (the "Company") hereby grants to
(the "Optionee"), a non-qualified stock option (the "Stock Option") to purchase
shares of Common Stock of the Company (the "Stock") at the price of   $      per
share, subject to the terms of this Agreement and the Plan.  The Stock Option is
granted as of        (the "Grant Date") and shall expire on        (the
"Expiration Date").  All terms used herein that are defined in the Plan shall
have the same meaning given them in the Plan.

      1. Timing of Exercise. Subject to Section 2 below and the discretion of
the Administrator to accelerate the vesting schedule hereunder, the Stock Option
shall become vested and exercisable with respect to the following whole number
of shares according to the timetable set forth below:

  Number of Years             Percentage of Shares         Cumulative Percentage
After Date of Grant      Becoming Available for Exercise         Available
-------------------      -------------------------------         ---------

Less than 1 year                       0%                            0%
At least 1 year                       50%                           50%
2 or more years                       50%                          100%

     Notwithstanding the foregoing, the Stock Option shall become fully vested
and exercisable for the reasons stated in Sections 2(a), 2(b) and 2(c) below.
The Stock Option shall remain exercisable until the Expiration Date, unless the
Stock Option is terminated sooner as provided herein.

     2.  Termination as Director.  If the Optionee ceases to be a Director of
the Company, the period within which to exercise the Stock Option may be subject
to earlier termination as set forth below.

          (a) Termination Due to Death.  If the Optionee ceases to be a Director
     due to death, the Stock Option held by the Optionee shall become fully
     vested and exercisable and may thereafter be exercised by the Optionee's
     beneficiary or legal representative for a period of twelve (12) months from
     the date of death, or until the Expiration Date, if earlier.

          (b) Termination Due to Disability.  If the Optionee ceases to be a
     Director as a result of incapacity due to physical or mental illness or
     disability, the Stock Option held by the Optionee shall become fully vested
     and exercisable and may thereafter be exercised by the Optionee (or
     Optionee's legal representative if Optionee is incapacitated) for a period
     of twelve (12) months from the date the Director ceases to serve as a
     Director or until the Expiration Date, if earlier.
<PAGE>

          (c) Termination in Connection with a Change of Control. If the
     Optionee ceases to be a Director as a result of a Change of Control, the
     Stock Option held by the Optionee shall become fully vested and exercisable
     and may thereafter be exercised by the Optionee for a period of twelve (12)
     months from the date of termination or until the Expiration Date, if
     earlier. Notwithstanding the foregoing, nothing in this Section 2(c) shall
     limit the Board's authority to take any action permitted pursuant to
     Section 3(c) of the Plan.

          (d) Other Termination.  If the Optionee ceases to be a Director for
     any reason other than death, disability or Change of Control, the Stock
     Option held by the Optionee may be exercised to the extent exercisable at
     the time of his termination, for a period of twelve (12) months from the
     date the Director ceases to serve as a Director or until the Expiration
     Date, if earlier.  The remaining portion of the Stock Option held by the
     Optionee shall immediately terminate and be of no further force and effect.

     3.  Manner of Exercise.  Subject to Section 4 below, the Stock Option may
be exercised in whole or in part by giving written notice of exercise to the
Company specifying the number of shares of Stock to be purchased.  Payment of
the purchase price may be made by one or more of the following methods:

          (a) In cash, by certified or bank check or other instrument acceptable
     to the Administrator;

          (b) In the form of shares of Stock that the Optionee has beneficially
     owned for more than six months and that are not then subject to
     restrictions under any Company plan. Such surrendered shares shall be
     valued at Fair Market Value on the exercise date; or

          (c) By the Optionee delivering to the Company a properly executed
     exercise notice together with irrevocable instructions to a broker to
     promptly deliver to the Company cash or a check payable and acceptable to
     the Company to pay the purchase price; provided that in the event the
     Optionee chooses to pay the purchase price as so provided, the Optionee and
     the broker shall comply with such procedures and enter into such agreements
     of indemnity and other agreements as the Administrator shall prescribe as a
     condition of such payment procedure.

     Payment instruments will be received subject to collection.  The delivery
of certificates representing the shares of Stock to be purchased pursuant to the
exercise of a Stock Option will be contingent upon receipt from the Optionee (or
a purchaser acting in the Optionee's stead in accordance with the provisions
contained in the Plan or this Agreement) by the Company of the full purchase
price for such shares and any required withholding taxes, and the fulfillment of
any other requirements contained in the Plan, this Agreement or applicable
provisions of law.

     4.  Trading Policy Restrictions.  Option exercises shall be subject to such
Company trading-policy-related restrictions, terms and conditions as may be
established by the Board, or in accordance with policies set by the Board, from
time to time.
<PAGE>

     5.  The Stock Option Transferable in Limited Circumstances.  Subject to
prior written notification to the Company by the Optionee, the Stock Option may
be transferred to a family member, a trust for the benefit of one or more family
members or a partnership in which family members are the only partners;
provided, however, that the transferee agrees in writing with the Company to be
bound by the terms of this Agreement and the Plan.  Except as permitted in the
preceding sentence, the Stock Option is not transferable otherwise than by will
or by the laws of descent and distribution, and shall be exercisable during the
Optionee's lifetime only by the Optionee.

     6.  Stock Option Shares.  The shares to be issued under the Plan are shares
of the Common Stock of the Company as constituted as of the date of this
Agreement, subject to adjustments pursuant to Section 3 of the Plan.

     7.  Rights as a Stockholder.  The Optionee shall have the rights of a
stockholder only as to shares of Stock acquired upon exercise of the Stock
Option and not as to any shares of Stock covered by unexercised Stock Options.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such shares are acquired.

     8.  Tax Status.  The Stock Option is not intended to qualify as an
incentive stock option under Section 422 of the Internal Revenue Code of 1986,
as amended.

     9.  The Plan.  The Stock Option is subject in all respects to the terms,
conditions, limitations and definitions contained in the Plan.  In the event of
any discrepancy or inconsistency between this Agreement and the Plan, the terms
and conditions of the Plan shall control.

     10.  No Obligation to Exercise Stock Option.  The grant and acceptance of
the Stock Option imposes no obligation on the Optionee to exercise it.

     11.  No Obligation to Continue as Director.  This Stock Option does not
confer upon the Optionee any rights with respect to continuance as a Director.

     12.  Notices.  Notices hereunder shall be mailed or delivered to the
Company at its principal place of business and shall be mailed or delivered to
the Optionee at the address on file with the Company or, in either case, at such
other address as one party may subsequently furnish to the other party in
writing.

     13.  Purchase Only for Investment.  To insure the Company's compliance with
the Securities Act of 1933, as amended, the Optionee agrees for himself or
herself, the Optionee's legal representatives and estate, or other persons who
acquire the right to exercise the Stock Option upon his or her death, that
shares will be purchased in the exercise of the Stock Option for investment
purposes only and not with a view to their distribution, as that term is used in
the Securities Act of 1933, as amended, unless in the opinion of counsel to the
Company such distribution is in compliance with or exempt from the registration
and prospectus requirements of that Act.

     14.  Governing Law.  This Agreement and the Stock Option shall be governed
by, and
<PAGE>

construed in accordance with, the laws of the State of Delaware, applied without
regard to conflict of law principles.

     15.  Beneficiary Designation.  The Optionee hereby designates the following
person(s) as the Optionee's beneficiary(ies) to whom shall be transferred any
rights under the Stock Option which survive the Optionee's death.  If the
Optionee names more than one primary beneficiary and one or more of such primary
beneficiaries die, the deceased primary beneficiary's interest will be
apportioned among any surviving primary beneficiaries before any contingent
beneficiary receives any amount, unless the Optionee indicates otherwise in a
signed and dated additional page.  The same rule shall apply within the category
of contingent beneficiaries.  Unless the Optionee has specified otherwise
herein, any rights which survive the Optionee's death will be divided equally
among the Optionee's primary beneficiaries or contingent beneficiaries, as the
case may be.  If no beneficiary survives the Optionee or there is no effective
beneficiary designation, the Optionee's estate shall be deemed to be his or her
beneficiary.
