                (a) Subject to Sections 3.1, 3.5, 3.6 and 4.4, each Share shall
        be released from the Forfeiture Restriction and the Transfer Restriction
        in accordance with the following schedule:

                Twenty (20%) of the Shares (rounded down to the next whole

                Restriction and the Transfer Restriction on each anniversary of
                the grant date, so that all of the Shares shall be released from
                the Forfeiture Restriction and the Transfer Restriction on the
                fifth (5th) anniversary after the grant date.

                (b) Any of the Shares which, from time to time, have not yet
        been released from the Forfeiture Restriction and the Transfer
        Restriction are referred to herein as "Unreleased Shares."

                (c) In the event of a Change of Control, or the death or
        Disability of the Holder, all of the Unreleased Shares shall cease to be
        subject to the Forfeiture Restriction or the Transfer Restriction.

        3.3 Legend. Certificates representing Shares issued pursuant to this
Agreement shall, until such Shares are released from the Forfeiture Restriction
and the Transfer Restriction and new certificates are issued therefor, bear the
following legend:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
        FORFEITURE AND CERTAIN RESTRICTIONS ON TRANSFERABILITY UNDER THE TERMS
        OF THAT CERTAIN RESTRICTED STOCK AGREEMENT BY AND BETWEEN ARDEN REALTY,
        INC. (THE "COMPANY"), ARDEN REALTY LIMITED PARTNERSHIP AND THE

        OR OTHERWISE DISPOSED OF UNDER ANY CIRCUMSTANCES, EXCEPT PURSUANT TO THE
        PROVISIONS OF SUCH AGREEMENT."

upon the release of Shares from the Forfeiture Restriction and the Transfer
Restriction, the Company shall cause new certificates to be issued with respect

        3.5 Restrictions On New Shares. In the event that the Holder receives
any new or additional or different shares or securities which are attributable
to the Holder in his capacity as the registered owner of Shares then subject to
Forfeiture Restriction and the Transfer Restriction, such new or additional or
different shares or securities shall be considered to be Shares under this
Agreement and shall be subject to the Forfeiture Restriction and the Transfer
Restriction, unless the Board or the Committee provides otherwise.

election under Section 83(b) of the Code with respect to the receipt of any of
the Shares.

Agreement, the Company shall be entitled to require payment in cash or deduction
from other compensation payable to the Holder of any sums required by federal,
state or local tax law to be withheld with respect to the issuance, lapsing of
restrictions on or exercise of the Shares. The Board or the Committee may, in
their discretion, allow the Holder to deliver shares of Common Stock owned by
the Holder duly endorsed for transfer to the Company with an aggregate Fair
Market Value on the date of delivery equal to the statutory minimum sums to be
withheld. The Company shall not be obligated to deliver any new certificate
representing vested Shares to the Holder or his legal representative unless and
until the Holder or his legal representative shall have paid or otherwise
satisfied in full the amount of all federal, state and local taxes applicable to
the taxable income of the Holder resulting from the grant of the Shares or the
lapse or removal of the Forfeiture Restriction and the Transfer Restriction.

                                   ARTICLE IV.
                                  MISCELLANEOUS

        4.1 Unreleased Shares Not Transferable. Unless otherwise permitted by
the Committee pursuant to the Plan, no Unreleased Shares or any interest or
right therein or part thereof shall be liable for the debts, contracts or
engagements of the Holder or his successors in interest or shall be subject to
disposition by transfer, alienation, anticipation, pledge, encumbrance,
assignment or any other means whether such disposition be voluntary or
involuntary or by operation of law by judgment, levy, attachment, garnishment or
any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect (the
"Transfer Restriction"); provided, however, that this Section 4.1 shall not
prevent transfers by will or by applicable laws of descent and distribution. In
case of a permitted transfer, the transferee or other recipient shall receive
and hold the Shares so transferred subject to the provisions of this Agreement,
and there shall be no further transfer of such Shares except in accordance with
the terms of this Section. Any transferee shall acknowledge the same by signing
a copy of this Agreement. Transfer or sale of the Shares is subject to
restrictions on transfer imposed by any applicable state and federal securities
laws.

be required to issue or deliver any certificate or certificates for shares of
stock pursuant to this Agreement prior to fulfillment of all of the following
conditions:

        exchanges on which such class of stock is then listed; and

        withheld, under federal, state and local tax laws, with respect to the
        issuance of Shares and/or the lapse or removal of the Forfeiture
        Restriction and/or the Transfer Restriction; and

                (c) The lapse of such reasonable period of time as the Committee
        may from time to time establish for reasons of administrative
        convenience.

                (d) The completion of any registration or other qualification of
        such shares under any state or federal law or under rulings or
        regulations of the Securities and Exchange Commission or of any other
        governmental regulatory body, which the Committee shall, in its absolute
        discretion, deem necessary or advisable; and

                (e) The obtaining of any approval or other clearance from any
        state or federal governmental agency which the Committee shall, in its

        4.3 Escrow.

                (a) Holder hereby authorizes and directs the Secretary of the
        Company, or such other person designated by the Company, to transfer the
        Unreleased Shares as to which the Forfeiture Option is effective from
        Holder to the Company.

                (b) To insure the availability for delivery of Holder's
        Unreleased Shares upon forfeiture pursuant to Section 3.1, Holder hereby
        appoints the Secretary, or any other person designated by the Company as
        escrow agent, as its attorney-in-fact to sell, assign and transfer unto
        the Company, such Unreleased Shares, if any, forfeited pursuant to the
        Forfeiture Option and shall, upon execution of this Agreement, deliver
        and deposit with the Secretary of the Company, or such other person
        designated by the Company, the share certificates representing the
        Unreleased Shares, together with the stock assignment duly endorsed in
        blank, attached hereto as Exhibit A. The Unreleased Shares and stock
        assignment shall be held by the Secretary in escrow, pursuant to the
        Joint Escrow Instructions of the Company and Holder attached as Exhibit
        B hereto, until the Forfeiture Restriction becomes effective as provided
        in Section 3.1, until such Unreleased Shares are vested, or until such
        time as this Agreement no longer is in effect. Upon vesting of the
        Unreleased Shares, the escrow agent shall promptly deliver to the Holder
        the certificate or certificates representing such Shares in the escrow
        agent's possession belonging to the Holder, and the escrow agent shall
        be discharged of all further obligations hereunder; provided, however,
        that the escrow agent shall nevertheless retain such certificate or
        certificates as escrow agent if so required pursuant to other
        restrictions imposed pursuant to this Agreement.

                (c) The Company, or its designee, shall not be liable for any
        act it may do or omit to do with respect to holding the Shares in escrow
        and while acting in good faith and in the exercise of its judgment.

        4.4 Ownership Limit and REIT Status. The Forfeiture Restriction and/or
the Transfer Restriction on the Shares shall not lapse if the lapsing of such
restrictions would likely result in any of the following:

                (a) a violation of the restrictions or limitations on ownership
        provided for from time to time under the terms of the organizational
        documents of the Company; or

                (b) income to the Company that could impair the Company's status
        as a real estate investment trust, within the meaning of Section 856
        through 860 of the Code.

        4.5 Notices. Any notice to be given under the terms of this Agreement to
the Company shall be addressed to the Company in care of its Secretary, and any
notice to be given to the Holder shall be addressed to him at the address given
beneath his signature hereto. By a notice given pursuant to this Section 4.5,
either party may hereafter designate a different address for notices to be given
to it or him. Any notice which is required to be given to the Holder shall, if
the Holder is then deceased, be given to the Holder's personal representative if
such representative has previously informed the Company of his status and
address by written notice under this Section 4.5. Any notice shall have been
deemed duly given when enclosed in a properly sealed envelope or wrapper


                                       7
<PAGE>

addressed as aforesaid, deposited (with postage prepaid) in a post office or
branch post office regularly maintained by the United States Postal Service.

        4.6 Rights as Stockholder. Except as otherwise provided herein, upon
delivery of the Shares to the escrow holder pursuant to Section 4.3, the Holder
shall have all the rights of a stockholder with respect to said shares, subject
to the restrictions herein, including the right to vote the shares and to
receive all dividends or other distributions paid or made with respect to the
Shares; provided, however, that any and all shares of Common Stock received by
the Holder with respect to such Shares as a result of stock dividends, stock
splits or any other form of recapitalization shall also be subject to the
Forfeiture Restriction and the Transfer Restriction until such restrictions on
the underlying Shares lapse or are removed pursuant to this Agreement.

        4.7 Titles. Titles are provided herein for convenience only and are not
to serve as a basis for interpretation or construction of this Agreement.

        4.8 Conformity to Securities Laws. The Holder acknowledges that the Plan
and this Agreement are intended to conform to the extent necessary with all
provisions of all applicable federal and state laws, rules and regulations
(including but not limited to, the Securities Act and the Exchange Act) and to
such approvals by any listing, regulatory or other governmental authority as
may, in the opinion of counsel for the Company, be necessary or advisable in
connection therewith. Notwithstanding anything herein to the contrary, this
Agreement shall be administered, and the Shares shall be issued, only in such a
manner as to conform to such laws, rules and regulations. To the extent
permitted by applicable law, the Plan, this Agreement and the Shares issued
hereunder shall be deemed amended to the extent necessary to conform to such
laws, rules and regulations.

        4.9 Limitations Applicable to Section 16 Persons and Performance-Based
Compensation. Notwithstanding any other provision of this Agreement, the Plan,
the Shares and this Agreement shall be subject to any additional limitations set
forth in any applicable exemptive rule under Section 16 of the Exchange Act
(including any amendment to Rule 16b-3) that are requirements for the
application of such exemptive rule. To the extent permitted by applicable law,
the Plan, this Agreement and the Shares issued hereunder shall be deemed amended
to the extent necessary to conform to such applicable exemptive rule.
Furthermore, notwithstanding any other provision of the Plan or this Agreement,
the Shares shall be subject to any additional limitations set forth in Section
162(m) of the Code (including any amendment to Section 162(m) of the Code) or
any regulations or rulings issued thereunder that are requirements for
qualification as performance-based compensation as described in Section
162(m)(4)(C) of the Code, and this Agreement shall be deemed amended to the
extent necessary to conform to such requirements unless the Committee shall have
determined that the Shares are not intended to so qualify.

        4.10 Governing Law. The laws of the State of Maryland shall govern the
interpretation, validity, administration, enforcement and performance of the
terms of this Agreement regardless of the law that might be applied under
principles of conflicts of laws.

        4.11 Survival of Terms. This Agreement shall apply to and bind Holder
and the Company and their respective permitted assignees and transferees, heirs,
legatees, executors, administrators and legal successors.

        4.12 Counterparts. This Agreement may be executed simultaneously in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

        4.13 Assignment. Except as otherwise provided herein, the Company's
rights and obligations hereunder may be assigned to any Company Subsidiary or to
any successor pursuant to a merger, consolidation or similar event. Subject to
the foregoing, this Agreement and the respective rights and obligations of the
parties hereto shall inure to the benefit of and be binding upon, the successors
and assigns of the parties.

        4.14 Invalid Provision. The invalidity or unenforceability of any
particular provision hereof shall not affect the other provisions hereof, and
this Agreement shall be construed in all respects as if such invalid or
unenforceable provision was omitted.

        1. In the event of forfeiture of any of the shares owned by Purchaser
pursuant to the Forfeiture Restriction set forth in the Agreement, the Company
and/or any assignee of the Company (referred to collectively for convenience
herein as the "Company") shall give to Purchaser and you a written notice
specifying the number of shares of stock forfeited and the date of forfeiture.
Purchaser and the Company hereby irrevocably authorize and direct you to effect

notice.

        2. As of the date of forfeiture indicated in such notice, you are
directed (a) to date the stock assignments necessary for the forfeiture and
transfer in question, (b) to fill in the number of shares being forfeited and

or its assignee.

        3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares. Purchaser does hereby irrevocably
constitute and appoint you as Purchaser's attorney-in-fact and agent for the
term of this escrow to execute, with respect to such securities, all documents
necessary or appropriate to make such securities negotiable and to complete any
transaction herein contemplated, including but not limited to the filing with
any applicable state blue sky authority of any required applications for consent
to, or notice of transfer of, the securities. Subject to the provisions of this

Purchaser a certificate or certificates representing the number of shares of
stock as are not then subject to the Forfeiture Restriction. Within one hundred
twenty (120) days after any voluntary or involuntary termination of Purchaser's
services to the Company for any or no reason, you will deliver to Purchaser a
certificate or certificates representing the aggregate number of shares held or
issued

vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

obligations hereunder, may rely upon the advice of such counsel, and the Company
shall reimburse you for any reasonable attorneys' fees incurred in connection
therewith.

        12. Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be an officer or agent of the Company or if you shall resign
by written notice to each party. In the event of any such termination, the
Company shall appoint a successor Escrow Agent.

respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.
