                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is made
and entered into as of August 4,1998, by and between ARDEN REALTY LIMITED
PARTNERSHIP, a Maryland limited partnership (the "Company"), ARDEN REALTY, INC.,
a Maryland corporation and the Company's general partner ("Arden" or the
"General Partner") and RICHARD S. ZIMAN ("Executive").

1.       EMPLOYMENT

         The Company and Arden (hereinafter referred to collectively as the
"Employers") hereby employ Executive and Executive hereby accepts employment
upon the terms and conditions set forth below.

2.       TERM AND RENEWAL

         2.1. Term. The term of this Agreement shall commence on October 9, 1996
(the "Effective Date"), and shall continue for three years from the Effective
Date (the "Original Employment Term"), on the terms and conditions set forth
below, unless sooner terminated as provided in Section 5.

         2.2. Extension. Following the expiration of the Original Employment
Term and provided that this Agreement has not been terminated pursuant to
Section 5, and every year thereafter, the Agreement shall be automatically
renewed for an additional 12-month period, effective on each anniversary date of
the Effective Date; provided, that if a Change in Control (as defined in Section
5.6), occurs during the original or extended term of this Agreement, this
Agreement shall continue in effect for a period not less than twenty-four (24)
months beyond the month in which such Change in Control occurred.

3.       COMPENSATION

         3.1. Base Compensation. For the services to be rendered by Executive
under this Agreement, Executive shall be entitled to receive, commencing as of
the Effective Date, an initial annual base compensation ("Base Compensation") of
$330,000, payable in substantially equal semi-monthly installments. The Base
Compensation shall be reviewed and adjusted annually as determined by the
Compensation Committee (the "Compensation Committee") of the Board of Directors
(the "Board") of the General Partner.

         3.2. Bonus Compensation. The Compensation Committee shall review
Executive's performance at least annually during each year of the Original
Employment Term and during any periods of automatic extension of this Agreement
pursuant to Section 2.2 and cause the Employers to award Executive a cash bonus
which the Compensation Committee shall reasonably determine as fairly
compensating and rewarding Executive for services rendered to the Employers
and/or as an incentive for continued service to the Employers. The amount of
such cash bonus shall be determined in the sole and absolute discretion of the
Compensation Committee and shall be dependent on, among other things, the
achievement of certain per share 




<PAGE>   2

performance levels by the Employers, including, without limitation, growth in
funds from operations, and Executive's performance and contribution to
increasing the funds from operations.

         3.3.     "Gross-Up" of Compensation.

                  (a) Base Compensation/Base Gross-Up. The amount of the Base
Compensation and any bonus payable to Executive pursuant to Section 3.1 and 3.2
above, shall be "grossed up" as necessary (on an after-tax basis) to compensate
for any additional withholding taxes or other expenses due as a result of
Executive's employment by both the Company and Arden and the implementation of
the Compensation Split (as defined in Section 10 below) with respect to the
financial obligations of the Company and Arden, respectively.

                  (b)      280G "Gross-Up".

                           (i)  Anything in this Agreement to the contrary
notwithstanding, if it shall be determined that any payment or distribution to
Executive or for his benefit (whether paid or payable or distributed or
distributable) pursuant to the terms of this Agreement or otherwise (the
"Payment") would be subject to the excise tax imposed by section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code") (the "Excise Tax"), then
Executive shall be entitled to receive from the Company an additional payment
(the "Gross-Up Payment") in an amount such that the net amount of the Payment
and the Gross-Up Payment retained by Executive after the calculation and
deduction of all Excise Taxes (including any interest or penalties imposed with
respect to such taxes) on the Payment and all federal, state and local income
tax, employment tax and Excise Tax (including any interest or penalties imposed
with respect to such taxes) on the Gross-Up Payment provided for in this Section
3.3(b) and taking into account any lost or reduced tax deductions on account of
the Gross-Up Payment, shall be equal to the Payment;

                           (ii) All determinations required to be made under
this Section 3.3(b), including whether and when the Gross-Up Payment is required
and the amount of such Gross-Up Payment, and the assumptions to be used in
arriving at such determinations shall be made by the Accountants (as defined
below) which shall provide Executive and the Company with detailed supporting
calculations with respect to such Gross-Up Payment within fifteen (15) business
days of the receipt of notice from Executive or the Company that Executive has
received or will receive a Payment. For the purposes of this Section 3.3(b), the
"Accountants" shall mean the Company's independent certified public accountants
serving immediately prior to the Change in Control (as defined in Section 5.6).
In the event that the Accountants are also serving as accountant or auditor for
the individual, entity or group effecting the Change in Control, Executive shall
appoint another nationally recognized public accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accountants hereunder). All fees and expenses of the Accountants shall
be borne solely by the Company. For the purposes of determining whether any of
the Payments will be subject to the Excise Tax and the amount of such Excise
Tax, such Payments will be treated as "parachute payments" within the meaning of
section 280G of the Code, and all "parachute payments" in 



                                       2
<PAGE>   3

excess of the "base amount" (as defined under section 280G(b)(3) of the Code)
shall be treated as subject to the Excise Tax, unless and except to the extent
that in the opinion of the Accountants such Payments (in whole or in part)
either do not constitute "parachute payments" or represent reasonable
compensation for services actually rendered (within the meaning of section
280G(b)(4) of the Code) in excess of the "base amount," or such "parachute
payments" are otherwise not subject to such Excise Tax. For purposes of
determining the amount of the Gross-Up Payment, Executive shall be deemed to pay
Federal income taxes at the highest applicable marginal rate of federal income
taxation for the calendar year in which the Gross-Up Payment is to be made and
to pay any applicable state and local income taxes at the highest applicable
marginal rate of taxation for the calendar year in which the Gross-Up Payment is
to be made, net of the maximum reduction in federal income taxes which could be
obtained from the deduction of such state or local taxes if paid in such year
(determined without regard to limitations on deductions based upon the amount of
Executive's adjusted gross income), and to have otherwise allowable deductions
for federal, state and local income tax purposes at least equal to those
disallowed because of the inclusion of the Gross-Up Payment in Executive's
adjusted gross income. To the extent practicable, any Gross-Up Payment with
respect to any Payment shall be paid by the Company at the time Executive is
entitled to receive the Payment and in no event will any Gross-Up Payment be
paid later than five days after the receipt by Executive of the Accountant's
determination. Any determination by the Accountants shall be binding upon the
Company and Executive. As a result of uncertainty in the application of section
4999 of the Code at the time of the initial determination by the Accountants
hereunder, it is possible that the Gross-Up Payment made will have been an
amount less than the Company should have paid pursuant to this Section 3.3(b)
(the "Underpayment"). In the event that the Company exhausts its remedies
pursuant to Section 3.3(b)(ii) and Executive is required to make a payment of
any Excise Tax, the Underpayment shall be promptly paid by the Company to or for
Executive's benefit; and

                           (iii) Executive shall notify the Company in writing
of any claim by the Internal Revenue Service that, if successful, would require
the payment by the Company of the Gross-Up Payment. Such notification shall be
given as soon as practicable after Executive is informed in writing of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which
Executive gives such notice to the Company (or such shorter period ending on the
date that any payment of taxes, interest and/or penalties with respect to such
claim is due). If the Company notifies Executive in writing prior to the
expiration of such period that it desires to contest such claim, Executive
shall:

                                    (A) give the Company any information
                reasonably requested by the Company relating to such claim;

                                    (B) take such action in connection with
                contesting such claim as the Company shall reasonably request in
                writing from time to time, including, without limitation,
                accepting legal representation with respect to such claim by an
                attorney reasonably selected by the Company;

                                    (C) cooperate with the Company in good faith
                in order to effectively contest such claim; and

                proceedings relating to such claims;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax or income tax (including interest
and penalties with respect thereto) imposed as a result of such representation
and payment of all related costs and expenses. Without limiting the foregoing
provisions of this Section 3.3(b), the Company shall control all proceedings
taken in connection with such contest and, at its sole option, may pursue or
forgo any and all administrative appeals, proceedings, hearings and conferences
with the taxing authority in respect of such claim and may, at its sole option,
either direct Executive to pay the tax claimed and sue for a refund or contest
the claim in any permissible manner, and Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs Executive to pay such
claim and sue for a refund, the Company shall advance the amount of such payment
to Executive, on an interest-free basis, and shall indemnify Executive for and
hold Executive harmless from, on an after-tax basis, any Excise Tax or income
tax (including interest or penalties with respect thereto) imposed with respect
to such advance or with respect to any imputed income with respect to such
advance (including as a result of any forgiveness by the Company of such
advance); provided, further, that any extension of the statute of limitations
relating to the payment of taxes for the taxable year of Executive with respect
to which such contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of the contest shall be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and Executive shall be entitled to settle or contest, as the case may
be, any other issue raised by the Internal Revenue Service or any other taxing
authority.

         3.4.     Benefits.

                  (a) Medical Insurance. The Employers shall provide to

Executive such disability and/or life insurance as the Employers in their sole
discretion may from time to time make available to their other executive
employees.

                  (c) Pension Plans, Etc. The Executive shall be entitled to
participate in all pension, 401(k) and other employee plans and benefits
established by the Employers on at least the same terms as the Employers' other

         5.2.     Severance Payment.

                  (a) Amount. In the event the Employers terminate Executive's
services hereunder pursuant to Section 5.1, Executive shall continue to render
services to the Employers pursuant to this Agreement until the date of

through the termination date. In addition to other compensation payable to
Executive for services rendered through the termination date, the Employers
shall pay Executive no later than the date of such termination, as a single
severance payment, an amount equal to the sum of: (i) three times Executive's

month period (or, if Executive has been employed less than thirty-six months,
the average annual Base Compensation for the period employed) plus (ii) an
amount equal to three times the highest annual bonus received by Executive
during the preceding thirty-six month period (or during the period Executive has

"Severance Amount"). In addition to payment of the Severance Amount, any
unvested stock options or restricted stock held by Executive shall become fully
vested as of the date of termination.

                  (b) Benefits. In the event Executive's employment hereunder is
terminated by the Employers without cause pursuant to Section 5.1 or by
Executive pursuant to Section 5.4 or 5.6, then in addition to paying Executive
the Severance Amount and providing for the full vesting of unvested stock
options or restricted stock held by Executive, the Employers shall continue to

         5.3. By the Employers For Cause. The Employers may terminate Executive
for cause at any time, upon written notice to Executive. For purposes of this
Agreement, "cause" shall mean:

                  (a) Executive's conviction for commission of a felony or a 
crime involving moral turpitude;

                  (b) Executive's willful commission of any act of theft,
embezzlement or misappropriation against the Employers which, in any such case,
is materially and demonstrably injurious to the Employers;

                  (c) Executive's willful and continued failure to substantially
perform Executive's duties hereunder (other than such failure resulting from
Executive's incapacity due to physical or mental illness), which failure is not
remedied within a reasonable time after written demand for substantial
performance is delivered by the Employers which specifically identifies the
manner in which the Employers believe that Executive has not substantially
performed Executive's duties; or

                  (d) Executive's death or Disability (as hereinafter defined).

         For purposes of this Section 5.3, no act, or failure to act, on
Executive's part shall be deemed "willful" unless done, or omitted to be done,
by Executive not in good faith.

         In the event Executive is terminated for cause pursuant to this Section
5.3, Executive shall have the right to receive Executive's compensation as
otherwise provided under this Agreement through the effective date of
termination. Executive shall have no further right to receive compensation or
other consideration from the Employers or have any other remedy whatsoever
against the Employers as a result of this Agreement or the termination of
Executive pursuant to this Section 5.3, except as set forth below with respect
to a termination due to Executive's Disability.

         In the event Executive is terminated by reason of Executive's death or
Disability, the Employers shall immediately pay Executive the Severance Amount
and shall continue to provide to Executive's spouse and children, as applicable,
all of the benefits described in Section 3.1 for a period of three years
commencing on the date of such termination. Said payment shall be in addition to
any disability insurance payments to which Executive is otherwise entitled and
any other compensation earned by Executive hereunder. In addition, any unvested
stock options or restricted stock held by Executive shall become fully vested as
of the date of termination. For purposes of this Agreement, the term
"Disability" shall mean a physical or mental incapacity as a result of which
Executive becomes unable to continue the proper performance of Executive's
duties hereunder for six consecutive calendar months or for shorter periods
aggregating 180 business days in any 12 month period, but only to the extent
that such definition does not violate the Americans with Disabilities Act.

         5.4. By Executive For Good Reason. Executive may terminate this
Agreement for good reason upon at least 10 days prior written notice to the
Employers. For purposes of this Agreement, "good reason" shall mean:

                  (a) the Employers' material breach of any of their respective
obligations hereunder and either such breach is incurable or, if curable, has
not been cured within fifteen (15) days following receipt of written notice by
Executive to the Employers of such breach by either of the Employers;

                  (b) any removal of Executive from one or more of the offices
specified in the first sentence of Section 4.1 without cause and without
Executive's prior written consent; or

                  (c) any material decrease in Executive's authority or

         In the event that Executive terminates this Agreement for good reason
pursuant to this Section 5.4, Executive shall have the right to receive
Executive's compensation as provided hereunder through the effective date of
termination and shall also have the same rights and remedies against the
Employers as Executive would have had if the Employers had terminated
Executive's employment without cause pursuant to Section 5.1 (including the
right to receive the Severance Amount payable and the Severance Benefits to be
provided under Section 5.2).

         5.5. Executive's Voluntary Termination. Executive may, at any time,
terminate this Agreement without good reason upon written notice delivered to
the Employers at least ninety (90) days prior to the effective date of
termination. In the event of such voluntary termination of this Agreement by
Executive: (i) Executive shall have the right to receive Executive's
compensation as provided hereunder through the effective date of termination,
and (ii) the Employers on the one hand, and Executive, on the other hand, shall
not have any further right or remedy against one another except as provided in
Sections 6, 7 and 8 hereof which shall remain in full force and effect.

         5.6. Change in Control. Executive may terminate this Agreement, upon at
least ten (10) days' prior written notice to the Employers at any time within
two (2) years after a "change in control" (as hereinafter defined) of the
Employers. In the event Executive terminates this Agreement within two (2) years
after a change in control pursuant to this Section 5.6, (i) Executive shall
continue to render services pursuant hereto and shall continue to receive
compensation, as provided hereunder, through the termination date, (ii) the
Employers shall pay Executive no later than the date of such termination, as a
single severance payment, an amount equal to the Severance Amount and (iii)
following such termination, the Employers shall provide the Severance Benefits

                                    (A) the stockholders of the General Partner,
                immediately before such merger, consolidation, share exchange or
                reorganization, own, directly or indirectly immediately

                reorganization, at least 80% of the combined voting power of the
                outstanding voting securities of the corporation that is the
                successor in such merger, consolidation, share exchange or
                reorganization (the "Surviving Company") in substantially the
                same proportion as their ownership of the Voting Securities
                immediately before such merger, consolidation, share exchange or
                reorganization; and

                                    (B) the individuals who were members of the
                Incumbent Board immediately prior to the execution of the
                agreement providing for such merger, consolidation, share

<PAGE>   10

operations, marketing data, business plans, strategies, employees, contracts,
financial records and accounts, projections and budgets, and similar

agrees that all such information and documents relating to the business of the
Employers whether they are prepared by Executive or come into Executive's
possession in any other way, are owned by the Employers and shall remain the
exclusive property of the Employers. Executive shall not misuse, misappropriate
or disclose any trade secrets of the Employers directly or indirectly, or use
them for Executive's own benefit, either during the term of this Agreement or at

Executive's employment with the Employers unless such action is either
previously agreed to in writing by the Employers or required by law.

7.       NON-SOLICITATION

hereunder is terminated, Executive shall not solicit or induce any of the
Employers' employees, agents or independent contractors to end their
relationship with either of the Employers, or recruit, hire or otherwise induce

period of one (1) year following the date of termination, with the exception of
the ownership of up to one percent (1%) of the securities of any publicly-traded
companies involved in such activities. Nothing herein shall relieve or limit
Executive's obligation to comply with Sections 6 and 7. The restrictions set

pursuant to Section 5.1, 5.4 or 5.6.

9.       INDEMNIFICATION

         To the fullest extent permitted under applicable law, the Employers
shall indemnify, defend and hold Executive harmless from and against any and all
causes of action, claims, demands, liabilities, damages, costs and expenses of
any nature whatsoever (collectively, "Damages") directly or indirectly arising
out of or relating to Executive discharging Executive's duties hereunder on

hereof is determined by any court of competent jurisdiction to be invalid or
unenforceable by reason of such provision extending the covenants and agreements

                              EMPLOYMENT AGREEMENT

         THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is made
and entered into as of August 4, 1998, by and between ARDEN REALTY LIMITED
PARTNERSHIP, a Maryland limited partnership (the "Company"), ARDEN REALTY, INC.,
a Maryland corporation and the Company's general partner ("Arden" or the
"General Partner") and VICTOR J. COLEMAN ("Executive").

1.       EMPLOYMENT

         The Company and Arden (hereinafter referred to collectively as the
"Employers") hereby employ Executive and Executive hereby accepts employment
upon the terms and conditions set forth below.

2.       TERM AND RENEWAL

         2.1. Term. The term of this Agreement shall commence on October 9, 1996
(the "Effective Date"), and shall continue for three years from the Effective
Date (the "Original Employment Term"), on the terms and conditions set forth
below, unless sooner terminated as provided in Section 5.

         2.2. Extension. Following the expiration of the Original Employment
Term and provided that this Agreement has not been terminated pursuant to
Section 5, and every year thereafter, the Agreement shall be automatically
renewed for an additional 12-month period, effective on each anniversary date of
the Effective Date; provided, that if a Change in Control (as defined in Section
5.6), occurs during the original or extended term of this Agreement, this
Agreement shall continue in effect for a period not less than twenty-four (24)
months beyond the month in which such Change in Control occurred.

3.       COMPENSATION

         3.1. Base Compensation. For the services to be rendered by Executive
under this Agreement, Executive shall be entitled to receive, commencing as of
the Effective Date, an initial annual base compensation ("Base Compensation") of
$275,000, payable in substantially equal semi-monthly installments. The Base
Compensation shall be reviewed and adjusted annually as determined by the
Compensation Committee (the "Compensation Committee") of the Board of Directors
(the "Board") of General Partner.

         3.2. Bonus Compensation. The Compensation Committee shall review
Executive's performance at least annually during each year of the Original
Employment Term and during any periods of automatic extension of this Agreement
pursuant to Section 2.2 and cause the Employers to award Executive a cash bonus
which the Compensation Committee shall reasonably determine as fairly
compensating and rewarding Executive for services rendered to the Employers
and/or as an incentive for continued service to the Employers. The amount of
such cash bonus shall be determined in the sole and absolute discretion of the
Compensation Committee and shall be dependent on, among other things, the
achievement of certain per share

performance levels by the Employers, including, without limitation, growth in
funds from operations, and Executive's performance and contribution to
increasing the funds from operations.

         3.3. "Gross-Up" of Compensation.

                  (a) Base Compensation/Base Gross-Up. The amount of the Base
Compensation and any bonus payable to Executive pursuant to Section 3.1 and 3.2
above, shall be "grossed up" as necessary (on an after-tax basis) to compensate
for any additional withholding taxes or other expenses due as a result of
Executive's employment by both the Company and Arden and the implementation of
the Compensation Split (as defined in Section 10 below) with respect to the
financial obligations of the Company and Arden, respectively.

                  (b) 280G "Gross-Up".

                           (i) Anything in this Agreement to the contrary
notwithstanding, if it shall be determined that any payment or distribution to
Executive or for his benefit (whether paid or payable or distributed or
distributable) pursuant to the terms of this Agreement or otherwise (the
"Payment") would be subject to the excise tax imposed by section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code") (the "Excise Tax"), then
Executive shall be entitled to receive from the Company an additional payment
(the "Gross-Up Payment") in an amount such that the net amount of the Payment
and the Gross-Up Payment retained by Executive after the calculation and
deduction of all Excise Taxes (including any interest or penalties imposed with
respect to such taxes) on the Payment and all federal, state and local income
tax, employment tax and Excise Tax (including any interest or penalties imposed
with respect to such taxes) on the Gross-Up Payment provided for in this Section
3.3(b) and taking into account any lost or reduced tax deductions on account of
the Gross-Up Payment, shall be equal to the Payment;

                           (ii) All determinations required to be made under
this Section 3.3(b), including whether and when the Gross-Up Payment is required
and the amount of such Gross-Up Payment, and the assumptions to be used in
arriving at such determinations shall be made by the Accountants (as defined
below) which shall provide Executive and the Company with detailed supporting
calculations with respect to such Gross-Up Payment within fifteen (15) business
days of the receipt of notice from Executive or the Company that Executive has
received or will receive a Payment. For the purposes of this Section 3.3(b), the
"Accountants" shall mean the Company's independent certified public accountants
serving immediately prior to the Change in Control (as defined in Section 5.6).
In the event that the Accountants are also serving as accountant or auditor for
the individual, entity or group effecting the Change in Control, Executive shall
appoint another nationally recognized public accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accountants hereunder). All fees and expenses of the Accountants shall
be borne solely by the Company. For the purposes of determining whether any of
the Payments will be subject to the Excise Tax and the amount of such Excise
Tax, such Payments will be treated as "parachute payments" within the meaning of
section 280G of the Code, and all "parachute payments" in 



                                       2
<PAGE>   3

excess of the "base amount" (as defined under section 280G(b)(3) of the Code)
shall be treated as subject to the Excise Tax, unless and except to the extent
that in the opinion of the Accountants such Payments (in whole or in part)
either do not constitute "parachute payments" or represent reasonable
compensation for services actually rendered (within the meaning of section
280G(b)(4) of the Code) in excess of the "base amount," or such "parachute
payments" are otherwise not subject to such Excise Tax. For purposes of
determining the amount of the Gross-Up Payment, Executive shall be deemed to pay
Federal income taxes at the highest applicable marginal rate of federal income
taxation for the calendar year in which the Gross-Up Payment is to be made and
to pay any applicable state and local income taxes at the highest applicable
marginal rate of taxation for the calendar year in which the Gross-Up Payment is
to be made, net of the maximum reduction in federal income taxes which could be
obtained from the deduction of such state or local taxes if paid in such year
(determined without regard to limitations on deductions based upon the amount of
Executive's adjusted gross income), and to have otherwise allowable deductions
for federal, state and local income tax purposes at least equal to those
disallowed because of the inclusion of the Gross-Up Payment in Executive's
adjusted gross income. To the extent practicable, any Gross-Up Payment with
respect to any Payment shall be paid by the Company at the time Executive is
entitled to receive the Payment and in no event will any Gross-Up Payment be
paid later than five days after the receipt by Executive of the Accountant's
determination. Any determination by the Accountants shall be binding upon the
Company and Executive. As a result of uncertainty in the application of section
4999 of the Code at the time of the initial determination by the Accountants
hereunder, it is possible that the Gross-Up Payment made will have been an
amount less than the Company should have paid pursuant to this Section 3.3(b)
(the "Underpayment"). In the event that the Company exhausts its remedies
pursuant to Section 3.3(b)(ii) and Executive is required to make a payment of
any Excise Tax, the Underpayment shall be promptly paid by the Company to or for
Executive's benefit; and

                           (iii) Executive shall notify the Company in writing
of any claim by the Internal Revenue Service that, if successful, would require
the payment by the Company of the Gross-Up Payment. Such notification shall be
given as soon as practicable after Executive is informed in writing of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which
Executive gives such notice to the Company (or such shorter period ending on the
date that any payment of taxes, interest and/or penalties with respect to such
claim is due). If the Company notifies Executive in writing prior to the
expiration of such period that it desires to contest such claim, Executive
shall:

                                    (A) give the Company any information
                           reasonably requested by the Company relating to such
                           claim;

                                    (B) take such action in connection with
                           contesting such claim as the Company shall reasonably
                           request in writing from time to time, including,
                           without limitation, accepting legal representation
                           with respect to such claim by an attorney reasonably
                           selected by the Company;



                                       3
<PAGE>   4

                                    (C) cooperate with the Company in good faith
                           in order to effectively contest such claim; and

                                    (D) permit the Company to participate in any
                           proceedings relating to such claims;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax or income tax (including interest
and penalties with respect thereto) imposed as a result of such representation
and payment of all related costs and expenses. Without limiting the foregoing
provisions of this Section 3.3(b), the Company shall control all proceedings
taken in connection with such contest and, at its sole option, may pursue or
forgo any and all administrative appeals, proceedings, hearings and conferences
with the taxing authority in respect of such claim and may, at its sole option,
either direct Executive to pay the tax claimed and sue for a refund or contest
the claim in any permissible manner, and Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs Executive to pay such
claim and sue for a refund, the Company shall advance the amount of such payment
to Executive, on an interest-free basis, and shall indemnify Executive for and
hold Executive harmless from, on an after-tax basis, any Excise Tax or income
tax (including interest or penalties with respect thereto) imposed with respect
to such advance or with respect to any imputed income with respect to such
advance (including as a result of any forgiveness by the Company of such
advance); provided, further, that any extension of the statute of limitations
relating to the payment of taxes for the taxable year of Executive with respect
to which such contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of the contest shall be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and Executive shall be entitled to settle or contest, as the case may
be, any other issue raised by the Internal Revenue Service or any other taxing
authority.

         3.4. Benefits.

                  (a) Medical Insurance. The Employers shall provide to
Executive, Executive's spouse and children, at its sole cost, such health,
dental and optical insurance as the Employers may from time to time make
available to their other executive employees.

                  (b) Life and Disability Insurance. The Employers shall provide
Executive such disability and/or life insurance as the Employers in their sole
discretion may from time to time make available to their other executive
employees.

                  (c) Pension Plans, Etc. The Executive shall be entitled to
participate in all pension, 401(k) and other employee plans and benefits
established by the Employers on at least the same terms as the Employers' other
executive employees.



                                       4

         3.5. Automobile Allowance. The Employers shall provide Executive with a
reasonable automobile allowance during the term of Executive's employment with
the Employers.

         3.6. Method of Payment. The monetary compensation payable and any
benefits due to Executive hereunder may be paid or provided in whole or in part,
from time to time, by the Employers and/or their respective subsidiaries and
affiliates, but shall at all times remain the responsibility of the Employers.

4.       POSITION AND DUTIES

         4.1. Position. Executive shall serve as President, Chief Operating
Officer and Director of the Employers. The Employers agree that the duties that
may be assigned Executive shall be the usual and customary duties of the offices
of President, Chief Operating Officer and Director. Executive shall have such
executive power and authority as shall reasonably be required to enable
Executive to discharge the duties of such offices. Executive may, at Executive's
discretion, serve the Employers and/or their respective subsidiaries and
affiliates in other offices and capacities in addition to the foregoing, but
shall not be required to do so. In the event the Employers and Executive
mutually agree that Executive shall terminate Executive's service in any one or
more of the aforementioned capacities, or Executive's service in one or more of
the aforementioned capacities is terminated, Executive's compensation, as
specified in this Agreement, shall not be diminished or reduced in any manner.

         4.2. Devotion of Time and Effort. Executive shall use Executive's good
faith best efforts and judgment in performing Executive's duties as required

hereunder.

         4.3. Other Activities. Executive may engage in other activities for
Executive's own account while employed hereunder, including without limitation
charitable, community and other business activities, provided that such other
activities do not materially interfere with the performance of Executive's
duties hereunder.

         4.4. Vacation. It is understood and agreed that Executive shall be
entitled to six weeks vacation per year. During such vacation periods, Executive
shall not be relieved of Executive's duties under this Agreement and there will
be no abatement or reduction of Executive's compensation hereunder.

         4.5. Business Expenses. The Employers shall promptly, but in no event
later than ten days after submission of a claim of expenditure, reimburse
Executive for all reasonable business expenses including, without limitation,
business seminar fees, professional association dues, bar dues, country club
membership fees and other reasonable entertainment expenses incurred by
Executive in connection with the business of the Employers and/or their
respective subsidiaries and affiliates, upon presentation to the Employers of
written receipts for such expenses. Such reimbursement shall also include, but

filings or disclosures, reasonably necessary for Executive to carry out
Executive's duties and responsibilities hereunder. In addition, the Employers
agree to provide Executive, as a condition to Executive's services hereunder,
such staff, equipment and office space as is reasonably necessary for Executive
to perform Executive's duties hereunder.

5.       TERMINATION

         5.1. By Employers Without Cause. The Employers may terminate this
Agreement without "cause" (as hereinafter defined) at any time following the
Effective Date, provided that the Employers first deliver to Executive the
Employers' written election to terminate this Agreement at least 90 days prior
to the effective date of termination.

         5.2.     Severance Payment.

                  (a) Amount. In the event the Employers terminate Executive's
services hereunder pursuant to Section 5.1, Executive shall continue to render
services to the Employers pursuant to this Agreement until the date of
termination and shall continue to receive compensation, as provided hereunder,
through the termination date. In addition to other compensation payable to
Executive for services rendered through the termination date, the Employers
shall pay Executive no later than the date of such termination, as a single
severance payment, an amount equal to the sum of: (i) three times Executive's
average annual Base Compensation paid hereunder for the preceding thirty-six
month period (or, if Executive has been employed less than thirty-six months,
the average annual Base Compensation for the period employed) plus (ii) an
amount equal to three times the highest annual bonus received by Executive
during the preceding thirty-six month period (or during the period Executive has
been employed hereunder if shorter than thirty-six months) (collectively, the
"Severance Amount"). In addition to payment of the Severance Amount, any
unvested stock options or restricted stock held by Executive shall become fully
vested as of the date of termination.

                  (b) Benefits. In the event Executive's employment hereunder is
terminated by the Employers without cause pursuant to Section 5.1 or by
Executive pursuant to Section 5.4 or 5.6, then in addition to paying Executive
the Severance Amount and providing for the full vesting of unvested stock
options or restricted stock held by Executive, the Employers shall continue to
provide to Executive and Executive's spouse and children, as applicable, all of
the benefits described in Section 3.3 for a period of three years commencing on
the date of such termination (the "Severance Benefits").



                                       6
<PAGE>   7

         5.3. By The Employers For Cause. The Employers may terminate Executive
for cause at any time, upon written notice to Executive. For purposes of this
Agreement, "cause" shall mean:

                  (a) Executive's conviction for commission of a felony or a
crime involving moral turpitude;

                  (b) Executive's willful commission of any act of theft,
embezzlement or misappropriation against the Employers which, in any such case,
is materially and demonstrably injurious to the Employers;

                  (c) Executive's willful and continued failure to substantially
perform Executive's duties hereunder (other than such failure resulting from
Executive's incapacity due to physical or mental illness), which failure is not
remedied within a reasonable time after written demand for substantial
performance is delivered by the Employers which specifically identifies the
manner in which the Employers believe that Executive has not substantially
performed Executive's duties; or

                  (d) Executive's death or Disability (as hereinafter defined).

         For purposes of this Section 5.3, no act, or failure to act, on
Executive's part shall be deemed "willful" unless done, or omitted to be done,
by Executive not in good faith.

         In the event Executive is terminated for cause pursuant to this Section
5.3, Executive shall have the right to receive Executive's compensation as
otherwise provided under this Agreement through the effective date of
termination. Executive shall have no further right to receive compensation or
other consideration from the Employers, or have any other remedy whatsoever
against the Employers, as a result of this Agreement or the termination of
Executive pursuant to this Section 5.3, except as set forth below with respect
to a termination due to Executive's Disability.

         In the event Executive is terminated by reason of Executive's death or
Disability, the Employers shall immediately pay Executive the Severance Amount
and shall continue to provide to Executive's spouse and children, as applicable,
all of the benefits described in Section 3.1 for a period of three years
commencing on the date of such termination. Said payment shall be in addition to
any disability insurance payments to which Executive is otherwise entitled and
any other compensation earned by Executive hereunder. In addition, any unvested
stock options or restricted stock held by Executive shall become fully vested as
of the date of termination. For purposes of this Agreement, the term
"Disability" shall mean a physical or mental incapacity as a result of which
Executive becomes unable to continue the proper performance of Executive's
duties hereunder for six consecutive calendar months or for shorter periods
aggregating 180 business days in any 12 month period, but only to the extent
that such definition does not violate the Americans with Disabilities Act.



                                       7
<PAGE>   8

         5.4. By Executive For Good Reason. Executive may terminate this
Agreement for good reason upon at least 10 days prior written notice to the
Employers. For purposes of this Agreement, "good reason" shall mean:

                  (a) the Employers' material breach of any of their respective
obligations hereunder and either such breach is incurable or, if curable, has
not been cured within fifteen (15) days following receipt of written notice by
Executive to the Employers of such breach by either of the Employers;

                  (b) any removal of Executive from one or more of the offices
specified in the first sentence of Section 4.1 without cause and without
Executive's prior written consent; or

                  (c) any material decrease in Executive's authority or
responsibilities hereunder without Executive's prior written consent.

         In the event that Executive terminates this Agreement for good reason
pursuant to this Section 5.4, Executive shall have the right to receive
Executive's compensation as provided hereunder through the effective date of
termination and shall also have the same rights and remedies against the
Employers as Executive would have had if the Employers had terminated
Executive's employment without cause pursuant to Section 5.1 (including the
right to receive the Severance Amount payable and the Severance Benefits to be
provided under Section 5.2).

         5.5. Executive's Voluntary Termination. Executive may, at any time,
terminate this Agreement without good reason upon written notice delivered to
the Employers at least ninety (90) days prior to the effective date of
termination. In the event of such voluntary termination of this Agreement by
Executive: (i) Executive shall have the right to receive Executive's
compensation as provided hereunder through the effective date of termination,
and (ii) the Employers, on the one hand, and Executive, on the other hand, shall
not have any further right or remedy against one another except as provided in
Sections 6, 7 and 8 hereof which shall remain in full force and effect.

         5.6. Change in Control. Executive may terminate this Agreement, upon at
least ten (10) days' prior written notice to the Employers, at any time within
two (2) years after a "change in control" (as hereinafter defined) of the
Employers. In the event Executive terminates this Agreement within two (2) years
after a change in control pursuant to this Section 5.6, (i) Executive shall
continue to render services pursuant hereto and shall continue to receive
compensation, as provided hereunder, through the termination date, (ii) the
Employers shall pay Executive no later than the date of such termination, as a
single severance payment, an amount equal to the Severance Amount and (iii)
following such termination, the Employers shall provide the Severance Benefits
as required by Section 5.2. For purposes of this Agreement, a "change in
control" shall mean the occurrence of any of the following events:

                  (a) the individuals constituting the Board as of the Effective
Date (the "Incumbent Board") cease for any reason to constitute at least
two-thirds (2/3rds) of the Board; provided, however, that if the election, or
nomination for election by the General Partner's 



                                       8
<PAGE>   9

stockholders, of any new director was approved by a vote of at least two-thirds
(2/3rds) of the Incumbent Board, such new director shall be considered a member
of the Incumbent Board;

                  (b) an acquisition of any voting securities of the General
Partner (the "Voting Securities") by any "person" (as the term "person" is used
for purposes of Section 13(d) or Section 14(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act")) immediately after which such person has
"beneficial ownership" (within the meaning of Rule 13d-3 promulgated under the
1934 Act) ("Beneficial Ownership") of 20% or more of the combined voting power
of the General Partner's then outstanding Voting Securities; or

                  (c) approval by the stockholders of the General Partner of:

                           (i) a merger, consolidation, share exchange or
reorganization involving the General Partner, unless

                                    (A) the stockholders of the General Partner,
                  immediately before such merger, consolidation, share exchange
                  or reorganization, own, directly or indirectly immediately
                  following such merger, consolidation, share exchange or
                  reorganization, at least 80% of the combined voting power of
                  the outstanding voting securities of the corporation that is
                  the successor in such merger, consolidation, share exchange or
                  reorganization (the "Surviving Company") in substantially the
                  same proportion as their ownership of the Voting Securities
                  immediately before such merger, consolidation, share exchange
                  or reorganization; and

                                    (B) the individuals who were members of the
                  Incumbent Board immediately prior to the execution of the
                  agreement providing for such merger, consolidation, share
                  exchange or reorganization constitute at least two-thirds
                  (2/3rds) of the members of the board of directors of the
                  Surviving Company;

                           (ii) a complete liquidation or dissolution of the
General Partner; or

6.       CONFIDENTIALITY

         During the term of Executive's employment under this Agreement,
Executive will have access to and become acquainted with various information
relating to the Employers' business operations, marketing data, business plans,
strategies, employees, contracts, financial records and accounts, projections
and budgets, and similar information. Executive agrees that to the extent such
information is not generally available to the public and gives either of the
Employers an advantage over competitors who do not know of or use such
information, such information and documents constitute "trade secrets" of the
Employers. Executive further agrees that all such information and documents
relating to the business of the Employers, whether they are prepared by
Executive or come into Executive's possession in any other way, are owned by the
Employers and shall remain the exclusive property of the Employers. Executive
shall not misuse, misappropriate or disclose any trade secrets of the Employers,
directly or indirectly, or use them for Executive's own benefit, either during
the term of this Agreement or at any time thereafter, except as may be necessary
or appropriate in the course of Executive's employment with the Employers,
unless such action is either previously agreed to in writing by the Employers or
required by law.

7.       NON-SOLICITATION

         For a period of one (1) year following the date Executive's employment
hereunder is terminated, Executive shall not solicit or induce any of the
Employers' employees, agents or independent contractors to end their
relationship with either of the Employers, or recruit, hire or otherwise induce
any such person to perform services for Executive, or any other person, firm or
company. The restrictions set forth in this Section 7 shall not apply if
Executive's employment is terminated pursuant to Section 5.1, 5.4 or 5.6.

8.       NON-COMPETITION AFTER TERMINATION

         For a period of one (1) year following the date Executive's employment
hereunder is terminated, Executive shall not engage in the acquisition,
renovation, management or leasing of any office properties in the Los Angeles,
Orange and San Diego counties of Southern California. In addition, Executive
shall not engage in any active or passive investment in or reasonably relating
to the acquisition, renovation, management or leasing of office properties in
the Los Angeles, Orange and San Diego counties of Southern California for a
period of one (1) year following the date of termination, with the exception of
the ownership of up to one percent (1%) of the securities of any publicly-traded
companies involved in such activities. Nothing herein shall relieve or limit
Executive's obligation to comply with Sections 6 and 7. The restrictions set
forth in this Section 8 shall not apply if Executive's employment is terminated
pursuant to Section 5.1, 5.4 or 5.6.

9.       INDEMNIFICATION

         To the fullest extent permitted under applicable law, the Employers
shall indemnify, defend and hold Executive harmless from and against any and all
causes of action, claims, demands, liabilities, damages, costs and expenses of
any nature whatsoever (collectively, "Damages") directly or indirectly arising
out of or relating to Executive discharging Executive's duties hereunder on
behalf of the Employers and/or their respective subsidiaries and affiliates, so
long as Executive acted in good faith within the course and scope of Executive's
duties with respect to the matter giving rise to the claim or Damages for which
Executive seeks indemnification.

10.      PAYMENT OF FINANCIAL OBLIGATIONS BY EMPLOYERS

         The payment or provision to the Executive by the Employers of any
remuneration, benefits or other financial obligations pursuant to this
Agreement, including, without limitation, the payment of Executive's Base
Compensation, any cash bonuses, the provision of benefits enumerated in Section
3.3, the reimbursement of business expenses pursuant to Section 4.5, the payment
(if applicable) of the Severance Amount and provision of the Severance Benefits
and any indemnification obligations, shall be allocated (the "Compensation
Split") 80% to the Company and 20% to Arden initially, subject to adjustment
from time to time by the Compensation Committee.

11.      GENERAL PROVISIONS

         11.1. Assignment; Binding Effect. None of the Employers or Executive
may assign, delegate or otherwise transfer this Agreement or any of their
respective rights or obligations hereunder without the prior written consent of

hereof is determined by any court of competent jurisdiction to be invalid or
unenforceable by reason of such provision extending the covenants and agreements
contained herein for too great a period of time or over too great a geographical
area, or being too extensive in any other respect, such provision shall be

proceeding.

                              EMPLOYMENT AGREEMENT

         THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is made
and entered into as of August 4, 1998, by and between ARDEN REALTY, INC., a
Maryland corporation (the "Company") and DIANA M. LAING ("Executive").

1.       EMPLOYMENT

         The Company hereby employs Executive and Executive hereby accepts
employment upon the terms and conditions set forth below.

2.       TERM AND RENEWAL

         2.1. Term. The term of this Agreement shall commence on January 1, 1998
(the "Effective Date"), and shall continue for three years from the Effective
Date (the "Original Employment Term"), on the terms and conditions set forth
below, unless sooner terminated as provided in Section 5.

         2.2. Extension. Following the expiration of the Original Employment
Term and provided that this Agreement has not been terminated pursuant to
Section 5, and every year thereafter, the Agreement shall be automatically
renewed for an additional 12-month period, effective on each anniversary date of
the Effective Date; provided, that if a Change in Control (as defined in Section
5.6), occurs during the original or extended term of this Agreement, this
Agreement shall continue in effect for a period not less than twenty-four (24)
months beyond the month in which such Change in Control occurred.

3.       COMPENSATION

         3.1. Base Compensation. For the services to be rendered by Executive
under this Agreement, Executive shall be entitled to receive, commencing as of
the Effective Date, an initial annual base compensation ("Base Compensation") of
$214,500 payable in substantially equal semi-monthly installments. The Base
Compensation shall be reviewed and adjusted annually as determined by the
Compensation Committee (the "Compensation Committee") of the Board of Directors
(the "Board") of the Company.

         3.2. Bonus Compensation. The Compensation Committee shall review
Executive's performance at least annually during each year of the Original
Employment Term and during any periods of automatic extension of this Agreement
pursuant to Section 2.2 and cause the Company to award Executive a cash bonus
which the Compensation Committee shall reasonably determine as fairly
compensating and rewarding Executive for services rendered to the Company and/or
as an incentive for continued service to the Company. The amount of such cash
bonus shall be determined in the sole and absolute discretion of the
Compensation Committee and shall be dependent on, among other things, the
achievement of certain per share performance levels by the Company, including,
without limitation, growth in funds from operations, and Executive's performance
and contribution to increasing the funds from operations.

         3.3. "Gross-Up" of Compensation.

                  (a) 280G "Gross-Up".

                           (i) Anything in this Agreement to the contrary
notwithstanding, if it shall be determined that any payment or distribution to
Executive or for his benefit (whether paid or payable or distributed or
distributable) pursuant to the terms of this Agreement or otherwise (the
"Payment") would be subject to the excise tax imposed by section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code") (the "Excise Tax"), then
Executive shall be entitled to receive from the Company an additional payment
(the "Gross-Up Payment") in an amount such that the net amount of the Payment
and the Gross-Up Payment retained by Executive after the calculation and
deduction of all Excise Taxes (including any interest or penalties imposed with
respect to such taxes) on the Payment and all federal, state and local income
tax, employment tax and Excise Tax (including any interest or penalties imposed
with respect to such taxes) on the Gross-Up Payment provided for in this Section
3.3(a) and taking into account any lost or reduced tax deductions on account of
the Gross-Up Payment, shall be equal to the Payment;

                           (ii) All determinations required to be made under
this Section 3.3(a), including whether and when the Gross-Up Payment is required
and the amount of such Gross-Up Payment, and the assumptions to be used in
arriving at such determinations shall be made by the Accountants (as defined
below) which shall provide Executive and the Company with detailed supporting
calculations with respect to such Gross-Up Payment within fifteen (15) business
days of the receipt of notice from Executive or the Company that Executive has
received or will receive a Payment. For the purposes of this Section 3.3(a), the
"Accountants" shall mean the Company's independent certified public accountants
serving immediately prior to the Change in Control (as defined in Section 5.6).
In the event that the Accountants are also serving as accountant or auditor for
the individual, entity or group effecting the Change in Control, Executive shall
appoint another nationally recognized public accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accountants hereunder). All fees and expenses of the Accountants shall
be borne solely by the Company. For the purposes of determining whether any of
the Payments will be subject to the Excise Tax and the amount of such Excise
Tax, such Payments will be treated as "parachute payments" within the meaning of
section 280G of the Code, and all "parachute payments" in excess of the "base
amount" (as defined under section 280G(b)(3) of the Code) shall be treated as
subject to the Excise Tax, unless and except to the extent that in the opinion
of the Accountants such Payments (in whole or in part) either do not constitute
"parachute payments" or represent reasonable compensation for services actually
rendered (within the meaning of section 280G(b)(4) of the Code) in excess of the
"base amount," or such "parachute payments" are otherwise not subject to such
Excise Tax. For purposes of determining the amount of the Gross-



                                       2
<PAGE>   3

Up Payment, Executive shall be deemed to pay Federal income taxes at the highest
applicable marginal rate of federal income taxation for the calendar year in
which the Gross-Up Payment is to be made and to pay any applicable state and
local income taxes at the highest applicable marginal rate of taxation for the
calendar year in which the Gross-Up Payment is to be made, net of the maximum
reduction in federal income taxes which could be obtained from the deduction of
such state or local taxes if paid in such year (determined without regard to
limitations on deductions based upon the amount of Executive's adjusted gross
income), and to have otherwise allowable deductions for federal, state and local
income tax purposes at least equal to those disallowed because of the inclusion
of the Gross-Up Payment in Executive's adjusted gross income. To the extent
practicable, any Gross-Up Payment with respect to any Payment shall be paid by
the Company at the time Executive is entitled to receive the Payment and in no
event will any Gross-Up Payment be paid later than five days after the receipt
by Executive of the Accountant's determination. Any determination by the
Accountants shall be binding upon the Company and Executive. As a result of
uncertainty in the application of section 4999 of the Code at the time of the
initial determination by the Accountants hereunder, it is possible that the
Gross-Up Payment made will have been an amount less than the Company should have
paid pursuant to this Section 3.3(a) (the "Underpayment"). In the event that the
Company exhausts its remedies pursuant to Section 3.3(a)(ii) and Executive is
required to make a payment of any Excise Tax, the Underpayment shall be promptly
paid by the Company to or for Executive's benefit; and

                           (iii) Executive shall notify the Company in writing
of any claim by the Internal Revenue Service that, if successful, would require
the payment by the Company of the Gross-Up Payment. Such notification shall be
given as soon as practicable after Executive is informed in writing of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which
Executive gives such notice to the Company (or such shorter period ending on the
date that any payment of taxes, interest and/or penalties with respect to such
claim is due). If the Company notifies Executive in writing prior to the
expiration of such period that it desires to contest such claim, Executive
shall:

                                    (A) give the Company any information
                  reasonably requested by the Company relating to such claim;

                                    (B) take such action in connection with
                  contesting such claim as the Company shall reasonably request
                  in writing from time to time, including, without limitation,
                  accepting legal representation with respect to such claim by
                  an attorney reasonably selected by the Company;

                                    (C) cooperate with the Company in good faith
                  in order to effectively contest such claim; and

                                    (D) permit the Company to participate in any
                  proceedings relating to such claims;



                                       3
<PAGE>   4

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax or income tax (including interest
and penalties with respect thereto) imposed as a result of such representation
and payment of all related costs and expenses. Without limiting the foregoing
provisions of this Section 3.3(a), the Company shall control all proceedings
taken in connection with such contest and, at its sole option, may pursue or
forgo any and all administrative appeals, proceedings, hearings and conferences
with the taxing authority in respect of such claim and may, at its sole option,
either direct Executive to pay the tax claimed and sue for a refund or contest
the claim in any permissible manner, and Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs Executive to pay such
claim and sue for a refund, the Company shall advance the amount of such payment
to Executive, on an interest-free basis, and shall indemnify Executive for and
hold Executive harmless from, on an after-tax basis, any Excise Tax or income
tax (including interest or penalties with respect thereto) imposed with respect
to such advance or with respect to any imputed income with respect to such
advance (including as a result of any forgiveness by the Company of such
advance); provided, further, that any extension of the statute of limitations
relating to the payment of taxes for the taxable year of Executive with respect
to which such contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of the contest shall be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and Executive shall be entitled to settle or contest, as the case may
be, any other issue raised by the Internal Revenue Service or any other taxing
authority.

         3.4. Loan. Subject to approval of the Shareholders of the Company of an
increase in the number of shares available through The 1996 Stock Option and
Incentive Plan of Arden Realty, Inc. and Arden Realty Limited Partnership, in an
amount sufficient to provide Executive with shares equal in value to $1,000,000
without reducing the number of shares available through the Plan for any other
purpose, the Company shall lend to Executive $1,000,000, which Executive may use
solely for the purpose of acquiring restricted stock of the Company through The
1996 Stock Option and Incentive Plan of Arden Realty, Inc. and Arden Realty
Limited Partnership, pursuant to the terms of the note attached hereto as
Exhibit "A" (the "Loan"). The stock acquired with the proceeds of this loan
shall be pledged as security for the Loan in accordance with the terms of the
Pledge Agreement attached hereto as Exhibit "B."

         3.5. Benefits.

                  (a) Medical Insurance. The Company shall provide to Executive,
Executive's spouse and children, at its sole cost, such health, dental and
optical insurance as the Company may from time to time make available to its
other executive employees.

                  (b) Life and Disability Insurance. The Company shall provide
Executive such disability and/or life insurance as the Company in its sole
discretion may from time to time make available to its other executive
employees.



                                       4

                  (c) Pension Plans, Etc. The Executive shall be entitled to
participate in all pension, 401(k) and other employee plans and benefits
established by the Company on at least the same terms as the Company's other
executive employees.

         3.6. Automobile Allowance. The Company shall provide Executive with a
reasonable automobile allowance during the term of Executive's employment with
the Company.

         3.7. Method of Payment. The monetary compensation payable and any
benefits due to Executive hereunder may be paid or provided in whole or in part,
from time to time, by the Company and/or its respective subsidiaries and
affiliates, but shall at all times remain the responsibility of the Company.

4.       POSITION AND DUTIES

         4.1. Position. Executive shall serve as Executive Vice President, Chief
Financial Officer and Secretary. The Company agrees that the duties that may be
assigned Executive shall be the usual and customary duties of the offices of

         4.3. Other Activities. Executive may engage in other activities for

5.       TERMINATION

         5.2. Severance Payment.

                  (a) Amount. In the event the Company terminates Executive's
services hereunder pursuant to Section 5.1, Executive shall continue to render
services to the Company pursuant to this Agreement until the date of termination
and shall continue to receive compensation, as provided hereunder, through the
termination date. In addition to other compensation payable to Executive for
services rendered through the termination date, the Company shall pay Executive
no later than the date of such termination, as a single severance payment, an
amount equal to the sum of: (i) three times Executive's average annual Base
Compensation paid hereunder for the preceding thirty-six month period (or, if
Executive has been employed less than thirty-six months, the average annual Base
Compensation for the period employed) plus (ii) an amount equal to three times
the highest annual bonus received by Executive during the preceding thirty-six
month period (or during the period Executive has been employed hereunder if
shorter than thirty-six months) (collectively, the "Severance Amount"). In
addition to payment of the Severance Amount, any unvested stock options or
restricted stock held by Executive shall become fully vested as of the date of
termination.

                  (b) Benefits. In the event Executive's employment hereunder is
terminated by the Company without cause pursuant to Section 5.1 or by Executive
pursuant to Section 5.4 or 5.6, then in addition to paying Executive the
Severance Amount and providing for the full vesting of unvested stock options or
restricted stock held by Executive, the Company shall continue to provide to
Executive and Executive's spouse and children, as applicable, all of the
benefits described in Section 3.1 for a period of three years commencing on the
date of such termination (the "Severance Benefits").

         5.3. By The Company For Cause. The Company may terminate Executive for
cause at any time, upon written notice to Executive. For purposes of this
Agreement, "cause" shall mean:

                  (a) Executive's conviction for commission of a felony or a
crime involving moral turpitude;

                  (b) Executive's willful commission of any act of theft,
embezzlement or misappropriation against the Company which, in any such case, is
materially and demonstrably injurious to the Company;

                  (c) Executive's willful and continued failure to substantially
perform Executive's duties hereunder (other than such failure resulting from
Executive's incapacity due to physical or mental illness), which failure is not
remedied within a reasonable time after written demand for substantial
performance is delivered by the Company which specifically identifies the manner
in which the Company believes that Executive has not substantially performed
Executive's duties; or

                  (d) Executive's death or Disability (as hereinafter defined).

         For purposes of this Section 5.3, no act, or failure to act, on
Executive's part shall be deemed "willful" unless done, or omitted to be done,
by Executive not in good faith.

         In the event Executive is terminated for cause pursuant to this Section
5.3, Executive shall have the right to receive Executive's compensation as
otherwise provided under this Agreement through the effective date of
termination. Executive shall have no further right to receive compensation or
other consideration from the Company, or have any other remedy whatsoever
against the Company, as a result of this Agreement or the termination of
Executive pursuant to this Section 5.3, except as set forth below with respect
to a termination due to Executive's Disability.

         In the event Executive is terminated by reason of Executive's death or
Disability, the Company shall immediately pay Executive a the Severance Amount
and shall continue to provide to Executive's spouse and children, as applicable,
all of the benefits described in Section 3.3 for a period of three years
commencing on the date of such termination. Said payments shall be in addition
to any disability insurance payments to which Executive is otherwise entitled
and any other compensation earned by Executive hereunder. In addition, any
unvested stock options or restricted stock held by Executive shall become fully
vested as of the date of termination. For purposes of this Agreement, the term
"Disability" shall mean a physical or mental incapacity as a result of which
Executive becomes unable to continue the proper performance of Executive's
duties hereunder for six consecutive calendar months or for shorter periods
aggregating 180 business days in any 12 month period, but only to the extent
that such definition does not violate the Americans with Disabilities Act.

         5.4. By Executive For Good Reason. Executive may terminate this
Agreement for good reason upon at least 10 days prior written notice to the
Company. For purposes of this Agreement, "good reason" shall mean:



                                       7
<PAGE>   8

                  (a) the Company's material breach of any of its respective
obligations hereunder and either such breach is incurable or, if curable, has
not been cured within fifteen (15) days following receipt of written notice by
Executive to the Company of such breach by the Company;

                  (b) any removal of Executive from one or more of the offices
specified in the first sentence of Section 4.1 without cause and without
Executive's prior written consent; or

                  (c) any material decrease in Executive's authority or
responsibilities hereunder without Executive's prior written consent.

         In the event that Executive terminates this Agreement for good reason
pursuant to this Section 5.4, Executive shall have the right to receive
Executive's compensation as provided hereunder through the effective date of
termination and shall also have the same rights and remedies against the Company
as Executive would have had if the Company had terminated Executive's employment
without cause pursuant to Section 5.1 (including the right to receive the
Severance Amount payable and the Severance Benefits to be provided under Section
5.2).

         5.5. Executive's Voluntary Termination. Executive may, at any time,
terminate this Agreement without good reason upon written notice delivered to
the Company at least ninety (90) days prior to the effective date of
termination. In the event of such voluntary termination of this Agreement by
Executive: (i) Executive shall have the right to receive Executive's
compensation as provided hereunder through the effective date of termination,
and (ii) the Company, on the one hand, and Executive, on the other hand, shall
not have any further right or remedy against one another except as provided in
Sections 6, 7 and 8 hereof which shall remain in full force and effect.

         5.6. Change in Control. Executive may terminate this Agreement, upon at
least ten (10) days' prior written notice to the Company, at any time within two
(2) years after a "change in control" (as hereinafter defined) of the Company.
In the event Executive terminates this Agreement within two (2) years after a
change in control pursuant to this Section 5.6, (i) Executive shall continue to
render services pursuant hereto and shall continue to receive compensation, as
provided hereunder, through the termination date, (ii) the Company shall pay
Executive no later than the date of such termination, as a single severance
payment, an amount equal to the Severance Amount, (iii) following such
termination, the Company shall provide the Severance Benefits as required by
Section 5.2 and (iv) any outstanding balance on the Loan shall be forgiven in
its entirety . For purposes of this Agreement, a "change in control" shall mean
the occurrence of any of the following events:

                  (a) the individuals constituting the Board as of the Effective
Date (the "Incumbent Board") cease for any reason to constitute at least
two-thirds (2/3rds) of the Board; provided, however, that if the election, or
nomination for election by the Company's stockholders, of any new director was
approved by a vote of at least two-thirds (2/3rds) of the Incumbent Board, such
new director shall be considered a member of the Incumbent Board;

                  (b) an acquisition of any voting securities of the Company
(the "Voting Securities") by any "person" (as the term "person" is used for
purposes of Section 13(d) or 



                                       8

Section 14(d) of the Securities Exchange Act of 1934, as amended (the "1934
Act")) immediately after which such person has "beneficial ownership" (within
the meaning of Rule 13d-3 promulgated under the 1934 Act) ("Beneficial
Ownership") of 20% or more of the combined voting power of the Company's then
outstanding Voting Securities; or

                  (c) approval by the stockholders of the Company of:

                           (i) a merger, consolidation, share exchange or
reorganization involving the Company, unless

                                    (A) the stockholders of the Company,
                  immediately before such merger, consolidation, share exchange
                  or reorganization, own, directly or indirectly immediately
                  following such merger, consolidation, share exchange or
                  reorganization, at least 80% of the combined voting power of
                  the outstanding voting securities of the corporation that is
                  the successor in such merger, consolidation, share exchange or
                  reorganization (the "Surviving Company") in substantially the
                  same proportion as their ownership of the Voting Securities
                  immediately before such merger, consolidation, share exchange
                  or reorganization; and

                                    (B) the individuals who were members of the
                  Incumbent Board immediately prior to the execution of the
                  agreement providing for such merger, consolidation, share
                  exchange or reorganization constitute at least two-thirds
                  (2/3rds) of the members of the board of directors of the
                  Surviving Company;

                           (ii) a complete liquidation or dissolution of the
Company; or

                          (iii) an agreement for the sale or other disposition
of all or substantially all of the assets of the Company.

                  (d) any Person is or becomes the Beneficial Owner of
securities of the Company representing ten percent (10%) or more of the combined
voting power of the Company's then outstanding securities and (A) the identity
of the Chief Executive Officer of the Company is changed during the period
beginning sixty (60) days before the attainment of the ten percent (10%)
beneficial ownership and ending two (2) years thereafter, or (B) individuals
constituting at least one-third (1/3) of the members of the Board at the
beginning of such period shall leave the Board during the period beginning sixty
(60) days before the attainment of the ten percent (10%) beneficial ownership
and ending two (2) years thereafter.

6.       CONFIDENTIALITY

         During the term of Executive's employment under this Agreement,
Executive will have access to and become acquainted with various information
relating to the Company's business operations, marketing data, business plans,
strategies, employees, contracts, financial records and accounts, projections
and budgets, and similar information. Executive agrees that to the extent such
information is not generally available to the public and gives the Company an
advantage over 



                                       9
<PAGE>   10

competitors who do not know of or use such information, such information and
documents constitute "trade secrets" of the Company. Executive further agrees
that all such information and documents relating to the business of the Company,
whether they are prepared by Executive or come into Executive's possession in
any other way, are owned by the Company and shall remain the exclusive property
of the Company. Executive shall not misuse, misappropriate or disclose any trade
secrets of the Company, directly or indirectly, or use them for Executive's own
benefit, either during the term of this Agreement or at any time thereafter,
except as may be necessary or appropriate in the course of Executive's
employment with the Company, unless such action is either previously agreed to
in writing by the Company or required by law.

7.       NON-SOLICITATION

         For a period of one (1) year following the date Executive's employment
hereunder is terminated, Executive shall not solicit or induce any of the
Company's employees, agents or independent contractors to end their relationship
with the Company, or recruit, hire or otherwise induce any such person to
perform services for Executive, or any other person, firm or company. The
restrictions set forth in this Section 7 shall not apply if Executive's
employment is terminated pursuant to Section 5.1, 5.4 or 5.6.

8.       NON-COMPETITION AFTER TERMINATION

         For a period of one (1) year following the date Executive's employment
hereunder is terminated, Executive shall not engage in the acquisition,
renovation, management or leasing of any office properties in the Los Angeles,
Orange and San Diego counties of Southern California. In addition, Executive
shall not engage in any active or passive investment in or reasonably relating
to the acquisition, renovation, management or leasing of office properties in
the Los Angeles, Orange and San Diego counties of Southern California for a
period of one (1) year following the date of termination, with the exception of
the ownership of up to one percent (1%) of the securities of any publicly-traded
companies involved in such activities. Nothing herein shall relieve or limit
Executive's obligation to comply with Sections 6 and 7. The restrictions set
forth in this Section 8 shall not apply if Executive's employment is terminated
pursuant to Section 5.1, 5.4 or 5.6.

9.       INDEMNIFICATION

         To the fullest extent permitted under applicable law, the Company shall
indemnify, defend and hold Executive harmless from and against any and all
causes of action, claims, demands, liabilities, damages, costs and expenses of
any nature whatsoever (collectively, "Damages") directly or indirectly arising
out of or relating to Executive discharging Executive's duties hereunder on
behalf of the Company and/or its respective subsidiaries and affiliates, so long
as Executive acted in good faith within the course and scope of Executive's
duties with respect to the matter giving rise to the claim or Damages for which
Executive seeks indemnification.

                              EMPLOYMENT AGREEMENT

        THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is made and
entered into as of August 4, 1998, by and between ARDEN REALTY, INC., a Maryland
corporation (the "Company") and ANDREW J. SOBEL ("Executive").

1.      EMPLOYMENT

        The Company hereby employs Executive and Executive hereby accepts
employment upon the terms and conditions set forth below.

2.      TERM AND RENEWAL

        2.1.    Term. The term of this Agreement shall commence on January 1,
1998 (the "Effective Date"), and shall continue for three years from the
Effective Date (the "Original Employment Term"), on the terms and conditions set
forth below, unless sooner terminated as provided in Section 5.

        2.2.    Extension. Following the expiration of the Original Employment
Term and provided that this Agreement has not been terminated pursuant to
Section 5, and every year thereafter, the Agreement shall be automatically
renewed for an additional 12-month period, effective on each anniversary date of
the Effective Date; provided, that if a Change in Control (as defined in Section
5.6), occurs during the original or extended term of this Agreement, this
Agreement shall continue in effect for a period not less than twenty-four (24)
months beyond the month in which such Change in Control occurred.

3.      COMPENSATION

        3.1.    Base Compensation. For the services to be rendered by Executive
under this Agreement, Executive shall be entitled to receive, commencing as of
the Effective Date, an initial annual base compensation ("Base Compensation") of
$187,500, payable in substantially equal semi-monthly installments. The Base
Compensation shall be reviewed and adjusted annually as determined by the
Compensation Committee (the "Compensation Committee") of the Board of Directors
(the "Board") of The Company.

        3.2.    Bonus Compensation. The Compensation Committee shall review
Executive's performance at least annually during each year of the Original
Employment Term and during any periods of automatic extension of this Agreement
pursuant to Section 2.2 and cause the Company to award Executive a cash bonus
which the Compensation Committee shall reasonably determine as fairly
compensating and rewarding Executive for services rendered to the Company and/or
as an incentive for continued service to the Company. The amount of such cash
bonus shall be determined in the sole and absolute discretion of the
Compensation Committee and shall be dependent on, among other things, the
achievement of certain per share performance levels by the Company, including,
without limitation, growth in funds from operations, and Executive's performance
and contribution to increasing the funds from operations.
<PAGE>   2

        3.3.    "Gross-Up" of Compensation.

                (a)     280G "Gross-Up".

                        (i)     Anything in this Agreement to the contrary
notwithstanding, if it shall be determined that any payment or distribution to
Executive or for his benefit (whether paid or payable or distributed or
distributable) pursuant to the terms of this Agreement or otherwise (the
"Payment") would be subject to the excise tax imposed by section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code") (the "Excise Tax"), then
Executive shall be entitled to receive from the Company an additional payment
(the "Gross-Up Payment") in an amount such that the net amount of the Payment
and the Gross-Up Payment retained by Executive after the calculation and
deduction of all Excise Taxes (including any interest or penalties imposed with
respect to such taxes) on the Payment and all federal, state and local income
tax, employment tax and Excise Tax (including any interest or penalties imposed
with respect to such taxes) on the Gross-Up Payment provided for in this Section
3.3(a) and taking into account any lost or reduced tax deductions on account of
the Gross-Up Payment, shall be equal to the Payment;

                        (ii)    All determinations required to be made under
this Section 3.3(a), including whether and when the Gross-Up Payment is required
and the amount of such Gross-Up Payment, and the assumptions to be used in
arriving at such determinations shall be made by the Accountants (as defined
below) which shall provide Executive and the Company with detailed supporting
calculations with respect to such Gross-Up Payment within fifteen (15) business
days of the receipt of notice from Executive or the Company that Executive has
received or will receive a Payment. For the purposes of this Section 3.3(a), the
"Accountants" shall mean the Company's independent certified public accountants
serving immediately prior to the Change in Control (as defined in Section 5.6).
In the event that the Accountants are also serving as accountant or auditor for
the individual, entity or group effecting the Change in Control, Executive shall
appoint another nationally recognized public accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accountants hereunder). All fees and expenses of the Accountants shall
be borne solely by the Company. For the purposes of determining whether any of
the Payments will be subject to the Excise Tax and the amount of such Excise
Tax, such Payments will be treated as "parachute payments" within the meaning of
section 280G of the Code, and all "parachute payments" in excess of the "base
amount" (as defined under section 280G(b)(3) of the Code) shall be treated as
subject to the Excise Tax, unless and except to the extent that in the opinion
of the Accountants such Payments (in whole or in part) either do not constitute
"parachute payments" or represent reasonable compensation for services actually
rendered (within the meaning of section 280G(b)(4) of the Code) in excess of the
"base amount," or such "parachute payments" are otherwise not subject to such
Excise Tax. For purposes of determining the amount of the Gross-Up Payment,
Executive shall be deemed to pay Federal income taxes at the highest applicable
marginal rate of federal income taxation for the calendar year in which the
Gross-Up Payment is to be made and to pay any applicable state and local income
taxes at the highest applicable marginal rate of taxation for the calendar year
in which the Gross-Up Payment is to be made, net 


                                       2
<PAGE>   3

of the maximum reduction in federal income taxes which could be obtained from
the deduction of such state or local taxes if paid in such year (determined
without regard to limitations on deductions based upon the amount of Executive's
adjusted gross income), and to have otherwise allowable deductions for federal,
state and local income tax purposes at least equal to those disallowed because
of the inclusion of the Gross-Up Payment in Executive's adjusted gross income.
To the extent practicable, any Gross-Up Payment with respect to any Payment
shall be paid by the Company at the time Executive is entitled to receive the
Payment and in no event will any Gross-Up Payment be paid later than five days
after the receipt by Executive of the Accountant's determination. Any
determination by the Accountants shall be binding upon the Company and
Executive. As a result of uncertainty in the application of section 4999 of the
Code at the time of the initial determination by the Accountants hereunder, it
is possible that the Gross-Up Payment made will have been an amount less than
the Company should have paid pursuant to this Section 3.3(a) (the
"Underpayment"). In the event that the Company exhausts its remedies pursuant to
Section 3.3(a)(ii) and Executive is required to make a payment of any Excise
Tax, the Underpayment shall be promptly paid by the Company to or for
Executive's benefit; and

                        (iii)   Executive shall notify the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable after Executive is informed in writing of such claim and
shall apprise the Company of the nature of such claim and the date on which such
claim is requested to be paid. Executive shall not pay such claim prior to the
expiration of the 30-day period following the date on which Executive gives such
notice to the Company (or such shorter period ending on the date that any
payment of taxes, interest and/or penalties with respect to such claim is due).
If the Company notifies Executive in writing prior to the expiration of such
period that it desires to contest such claim, Executive shall:

                                (A)     give the Company any information
                reasonably requested by the Company relating to such claim;

                                (B)     take such action in connection with
                contesting such claim as the Company shall reasonably request in
                writing from time to time, including, without limitation,
                accepting legal representation with respect to such claim by an
                attorney reasonably selected by the Company;

                                (C)     cooperate with the Company in good faith
                in order to effectively contest such claim; and

                                (D)     permit the Company to participate in any
                proceedings relating to such claims;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax or income tax (including interest
and penalties with respect thereto) imposed as a result of such


                                       3

representation and payment of all related costs and expenses. Without limiting
the foregoing provisions of this Section 3.3(a), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forgo any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and Executive agrees to
prosecute such contest to a determination before any administrative tribunal, in
a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine; provided, however, that if the Company directs
Executive to pay such claim and sue for a refund, the Company shall advance the
amount of such payment to Executive, on an interest-free basis, and shall
indemnify Executive for and hold Executive harmless from, on an after-tax basis,
any Excise Tax or income tax (including interest or penalties with respect
thereto) imposed with respect to such advance or with respect to any imputed
income with respect to such advance (including as a result of any forgiveness by
the Company of such advance); provided, further, that any extension of the
statute of limitations relating to the payment of taxes for the taxable year of
Executive with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. Furthermore, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder and Executive shall be entitled to settle or contest,
as the case may be, any other issue raised by the Internal Revenue Service or
any other taxing authority.

        3.4.    Loan. Subject to approval of the Shareholders of the Company of
an increase in the number of shares available through The 1996 Stock Option and
Incentive Plan of Arden Realty, Inc. and Arden Realty Limited Partnership, in an
amount sufficient to provide Executive with shares equal in value to $1,000,000
without reducing the number of shares available through the Plan for any other
purpose, the Company shall lend to Executive $1,000,000, which Executive may use
solely for the purpose of acquiring restricted stock of the Company through The
1996 Stock Option and Incentive Plan of Arden Realty, Inc. and Arden Realty

5.      TERMINATION

        5.1.    By the Company Without Cause. The Company may terminate this
Agreement without "cause" (as hereinafter defined) at any time following the
Effective Date, provided that the Company first delivers to Executive the
Company's written election to terminate this Agreement at least 90 days prior to
the effective date of termination.

        5.2.    Severance Payment.

                (a)     Amount. In the event the Company terminates Executive's
services hereunder pursuant to Section 5.1, Executive shall continue to render
services to the Company pursuant to this Agreement until the date of termination
and shall continue to receive compensation, as provided hereunder, through the
termination date. In addition to other compensation payable to Executive for
services rendered through the termination date, the Company shall pay Executive
no later than the date of such termination, as a single severance payment, an
amount equal to the sum of: (i) three times Executive's average annual Base
Compensation paid hereunder for the preceding thirty-six month period (or, if
Executive has been employed less than thirty-six months, the average annual Base
Compensation for the period employed) plus (ii) an amount equal to three times
the highest annual bonus received by Executive during the preceding thirty-six
month period (or during the period Executive has been employed hereunder if
shorter than thirty-six months) (collectively, the "Severance Amount"). In
addition to payment of the Severance Amount, any unvested stock options or
restricted stock held by Executive shall become fully vested as of the date of
termination.


                                       6
<PAGE>   7

                (b)     Benefits. In the event Executive's employment hereunder
is terminated by the Company without cause pursuant to Section 5.1 or by
Executive pursuant to Section 5.4 or 5.6, then in addition to paying Executive
the Severance Amount and providing for the full vesting of unvested stock
options or restricted stock held by Executive, the Company shall continue to
provide to Executive and Executive's spouse and children, as applicable, all of
the benefits described in Section 3.3 for a period of three years commencing on
the date of such termination (the "Severance Benefits").

        5.3.    By The Company For Cause. The Company may terminate Executive
for cause at any time, upon written notice to Executive. For purposes of this
Agreement, "cause" shall mean:

                (a)     Executive's conviction for commission of a felony or a
crime involving moral turpitude;

                (b)     Executive's willful commission of any act of theft,
embezzlement or misappropriation against the Company which, in any such case, is
materially and demonstrably injurious to the Company;

                (c)     Executive's willful and continued failure to
substantially perform Executive's duties hereunder (other than such failure
resulting from Executive's incapacity due to physical or mental illness), which
failure is not remedied within a reasonable time after written demand for
substantial performance is delivered by the Company which specifically
identifies the manner in which the Company believes that Executive has not
substantially performed Executive's duties; or

                (d)     Executive's death or Disability (as hereinafter
defined).

        For purposes of this Section 5.3, no act, or failure to act, on
Executive's part shall be deemed "willful" unless done, or omitted to be done,
by Executive not in good faith.

        In the event Executive is terminated for cause pursuant to this Section
5.3, Executive shall have the right to receive Executive's compensation as
otherwise provided under this Agreement through the effective date of
termination. Executive shall have no further right to receive compensation or
other consideration from the Company, or have any other remedy whatsoever
against the Company, as a result of this Agreement or the termination of
Executive pursuant to this Section 5.3, except as set forth below with respect
to a termination due to Executive's Disability.

        In the event Executive is terminated by reason of Executive's death or
Disability, the Company shall immediately pay Executive the Severance Amount and
shall continue to provide to provide to Executive's spouse and children, as
applicable, all of the benefits described in Section 3.1 for a period of three
years commencing on the date of such termination. Said payment shall be in
addition to any disability insurance payments to which Executive is otherwise
entitled and any other compensation earned by Executive hereunder. In addition,
any unvested stock options or restricted stock held by Executive shall become
fully vested as of the 


                                       7
<PAGE>   8

date of termination. For purposes of this Agreement, the term "Disability" shall
mean a physical or mental incapacity as a result of which Executive becomes
unable to continue the proper performance of Executive's duties hereunder for
six consecutive calendar months or for shorter periods aggregating 180 business
days in any 12 month period, but only to the extent that such definition does
not violate the Americans with Disabilities Act.

        5.4.    By Executive For Good Reason. Executive may terminate this
Agreement for good reason upon at least 10 days prior written notice to the
Company. For purposes of this Agreement, "good reason" shall mean:

                (a)     the Company's material breach of any of its respective
obligations hereunder and either such breach is incurable or, if curable, has
not been cured within fifteen (15) days following receipt of written notice by
Executive to the Company of such breach by the Company;

                (b)     any removal of Executive from one or more of the offices
specified in the first sentence of Section 4.1 without cause and without
Executive's prior written consent; or

                (c)     any material decrease in Executive's authority or
responsibilities hereunder without Executive's prior written consent.

        In the event that Executive terminates this Agreement for good reason
pursuant to this Section 5.4, Executive shall have the right to receive
Executive's compensation as provided hereunder through the effective date of
termination and shall also have the same rights and remedies against the Company
as Executive would have had if the Company had terminated Executive's employment
without cause pursuant to Section 5.1 (including the right to receive the
Severance Amount payable and the Severance Benefits to be provided under Section
5.2).

        5.5.    Executive's Voluntary Termination. Executive may, at any time,
terminate this Agreement without good reason upon written notice delivered to
the Company at least ninety (90) days prior to the effective date of
termination. In the event of such voluntary termination of this Agreement by
Executive: (i) Executive shall have the right to receive Executive's
compensation as provided hereunder through the effective date of termination,
and (ii) the Company, on the one hand, and Executive, on the other hand, shall
not have any further right or remedy against one another except as provided in
Sections 6, 7 and 8 hereof which shall remain in full force and effect.

        5.6.    Change in Control. Executive may terminate this Agreement, upon
at least ten (10) days' prior written notice to the Company, at any time within
two (2) years after a "change in control" (as hereinafter defined) of the
Company. In the event Executive terminates this Agreement within two (2) years
after a change in control pursuant to this Section 5.6, (i) Executive shall
continue to render services pursuant hereto and shall continue to receive
compensation, as provided hereunder, through the termination date, (ii) the
Company shall pay Executive no later than the date of such termination, as a
single severance payment, an amount equal to the Severance Amount, (iii)
following such termination, the Company shall provide the 


                                       8
<PAGE>   9

Severance Benefits as required by Section 5.2, and (iv) any outstanding balance
on the Loan shall be forgiven in its entirety. For purposes of this Agreement, a
"change in control" shall mean the occurrence of any of the following events:

the Effective Date (the "Incumbent Board") cease for any reason to constitute at
least two-thirds (2/3rds) of the Board; provided, however, that if the election,
or nomination for election by the Company's stockholders, of any new director
was approved by a vote of at least two-thirds (2/3rds) of the Incumbent Board,
such new director shall be considered a member of the Incumbent Board;

                (b)     an acquisition of any voting securities of the Company
(the "Voting Securities") by any "person" (as the term "person" is used for
purposes of Section 13(d) or Section 14(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act")) immediately after which such person has
"beneficial ownership" (within the meaning of Rule 13d-3 promulgated under the
1934 Act) ("Beneficial Ownership") of 20% or more of the combined voting power
of the Company's then outstanding Voting Securities; or

                (c)     approval by the stockholders of the Company of:

                        (i)     a merger, consolidation, share exchange or
reorganization involving the Company, unless

                                (A)     the stockholders of the Company,
                immediately before such merger, consolidation, share exchange or
                reorganization, own, directly or indirectly immediately

                reorganization, at least 80% of the combined voting power of the
                outstanding voting securities of the corporation that is the
                successor in such merger, consolidation, share exchange or
                reorganization (the "Surviving Company") in substantially the
                same proportion as their ownership of the Voting Securities
                immediately before such merger, consolidation, share exchange or
                reorganization; and

                                (B)     the individuals who were members of the
                Incumbent Board immediately prior to the execution of the
                agreement providing for such merger, consolidation, share
                exchange or reorganization constitute at least two-thirds
                (2/3rds) of the members of the board of directors of the
                Surviving Company;

                        (ii)    a complete liquidation or dissolution of the
Company; or

                        (iii)   an agreement for the sale or other disposition

                                       9
<PAGE>   10

changed during the period beginning sixty (60) days before the attainment of the
ten percent (10%) beneficial ownership and ending two (2) years thereafter, or
(B) individuals constituting at least one-third (1/3) of the members of the
Board at the beginning of such period shall leave the Board during the period
beginning sixty (60) days before the attainment of the ten percent (10%)
beneficial ownership and ending two (2) years thereafter.

6.      CONFIDENTIALITY

        During the term of Executive's employment under this Agreement,
Executive will have access to and become acquainted with various information
relating to the Company's business operations, marketing data, business plans,
strategies, employees, contracts, financial records and accounts, projections
and budgets, and similar information. Executive agrees that to the extent such
information is not generally available to the public and gives the Company an
advantage over competitors who do not know of or use such information, such
information and documents constitute "trade secrets" of the Company. Executive
further agrees that all such information and documents relating to the business
of the Company, whether they are prepared by Executive or come into Executive's
possession in any other way, are owned by the Company and shall remain the
exclusive property of the Company. Executive shall not misuse, misappropriate or
disclose any trade secrets of the Company, directly or indirectly, or use them
for Executive's own benefit, either during the term of this Agreement or at any
time thereafter, except as may be necessary or appropriate in the course of
Executive's employment with the Company, unless such action is either previously
agreed to in writing by the Company or required by law.

        For a period of one (1) year following the date Executive's employment
hereunder is terminated, Executive shall not solicit or induce any of the
Company's employees, agents or independent contractors to end their relationship
with the Company, or recruit, hire or otherwise induce any such person to
perform services for Executive, or any other person, firm or company. The
restrictions set forth in this Section 7 shall not apply if Executive's
employment is terminated pursuant to Section 5.1, 5.4 or 5.6.

8.      NON-COMPETITION AFTER TERMINATION

        For a period of one (1) year following the date Executive's employment
hereunder is terminated, Executive shall not engage in the acquisition,
renovation, management or leasing of any office properties in the Los Angeles,
Orange and San Diego counties of Southern California. In addition, Executive
shall not engage in any active or passive investment in or reasonably relating
to the acquisition, renovation, management or leasing of office properties in
the Los Angeles, Orange and San Diego counties of Southern California for a
period of one (1) year following the date of termination, with the exception of
the ownership of up to one percent (1%) of the securities of any publicly-traded
companies involved in such activities. Nothing herein shall relieve or limit
Executive's obligation to comply with Sections 6 and 7. The restrictions set


                                       10
<PAGE>   11

forth in this Section 8 shall not apply if Executive's employment is terminated
pursuant to Section 5.1, 5.4 or 5.6.

9.      INDEMNIFICATION

        To the fullest extent permitted under applicable law, the Company shall
indemnify, defend and hold Executive harmless from and against any and all
causes of action, claims, demands, liabilities, damages, costs and expenses of
any nature whatsoever (collectively, "Damages") directly or indirectly arising
out of or relating to Executive discharging Executive's duties hereunder on
behalf of the Company and/or its respective subsidiaries and affiliates, so long
as Executive acted in good faith within the course and scope of Executive's
duties with respect to the matter giving rise to the claim or Damages for which
Executive seeks indemnification.

10.     GENERAL PROVISIONS

        10.1.   Assignment; Binding Effect. Neither the Company or Executive may

                              EMPLOYMENT AGREEMENT

            THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is made
and entered into as of August 4, 1998, by and between ARDEN REALTY, INC., a
Maryland corporation (the "Company") and HERBERT PORTER ("Executive").

1.      EMPLOYMENT

        The Company hereby employs Executive and Executive hereby accepts
employment upon the terms and conditions set forth below.

2.      TERM AND RENEWAL

        2.1.    Term. The term of this Agreement shall commence on January 1,
1998 (the "Effective Date"), and shall continue for two years from the Effective
Date (the "Original Employment Term"), on the terms and conditions set forth
below, unless sooner terminated as provided in Section 5.

        2.2.    Extension. Following the expiration of the Original Employment
Term and provided that this Agreement has not been terminated pursuant to
Section 5, and every year thereafter, the Agreement shall be automatically
renewed for an additional 12-month period, effective on each anniversary date of
the Effective Date; provided, that if a Change in Control (as defined in Section
5.6), occurs during the original or extended term of this Agreement, this
Agreement shall continue in effect for a period not less than two (2) years
beyond the month in which such Change in Control occurred.

3.      COMPENSATION

        3.1.    Base Compensation. For the services to be rendered by Executive
under this Agreement, Executive shall be entitled to receive, commencing as of
the Effective Date, an initial annual base compensation ("Base Compensation") of
$143,000, payable in substantially equal semi-monthly installments. The Base
Compensation shall be reviewed and adjusted annually as determined by the
Compensation Committee (the "Compensation Committee") of the Board of Directors
(the "Board") of The Company.

        3.2.    Bonus Compensation. The Compensation Committee shall review
Executive's performance at least annually during each year of the Original
Employment Term and during any periods of automatic extension of this Agreement
pursuant to Section 2.2 and cause the Company to award Executive a cash bonus
which the Compensation Committee shall reasonably determine as fairly
compensating and rewarding Executive for services rendered to the Company and/or
as an incentive for continued service to the Company. The amount of such cash
bonus shall be determined in the sole and absolute discretion of the
Compensation Committee and shall be dependent on, among other things, the
achievement of certain per share performance levels by the Company, including,
without limitation, growth in funds from operations, and Executive's performance
and contribution to increasing the funds from operations.

        3.3.    "Gross-Up" of Compensation.

                (a)     280G "Gross-Up".

                        (i)     Anything in this Agreement to the contrary
notwithstanding, if it shall be determined that any payment or distribution to
Executive or for his benefit (whether paid or payable or distributed or
distributable) pursuant to the terms of this Agreement or otherwise (the
"Payment") would be subject to the excise tax imposed by section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code") (the "Excise Tax"), then
Executive shall be entitled to receive from the Company an additional payment
(the "Gross-Up Payment") in an amount such that the net amount of the Payment
and the Gross-Up Payment retained by Executive after the calculation and
deduction of all Excise Taxes (including any interest or penalties imposed with
respect to such taxes) on the Payment and all federal, state and local income
tax, employment tax and Excise Tax (including any interest or penalties imposed
with respect to such taxes) on the Gross-Up Payment provided for in this Section
3.3(a) and taking into account any lost or reduced tax deductions on account of
the Gross-Up Payment, shall be equal to the Payment;

                        (ii)    All determinations required to be made under
this Section 3.3(a), including whether and when the Gross-Up Payment is required
and the amount of such Gross-Up Payment, and the assumptions to be used in
arriving at such determinations shall be made by the Accountants (as defined
below) which shall provide Executive and the Company with detailed supporting
calculations with respect to such Gross-Up Payment within fifteen (15) business
days of the receipt of notice from Executive or the Company that Executive has
received or will receive a Payment. For the purposes of this Section 3.3(a), the
"Accountants" shall mean the Company's independent certified public accountants
serving immediately prior to the Change in Control (as defined in Section 5.6).
In the event that the Accountants are also serving as accountant or auditor for
the individual, entity or group effecting the Change in Control, Executive shall
appoint another nationally recognized public accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accountants hereunder). All fees and expenses of the Accountants shall
be borne solely by the Company. For the purposes of determining whether any of
the Payments will be subject to the Excise Tax and the amount of such Excise
Tax, such Payments will be treated as "parachute payments" within the meaning of
section 280G of the Code, and all "parachute payments" in excess of the "base
amount" (as defined under section 280G(b)(3) of the Code) shall be treated as
subject to the Excise Tax, unless and except to the extent that in the opinion
of the Accountants such Payments (in whole or in part) either do not constitute
"parachute payments" or represent reasonable compensation for services actually
rendered (within the meaning of section 280G(b)(4) of the Code) in excess of the
"base amount," or such "parachute payments" are otherwise not subject to such
Excise Tax. For purposes of determining the amount of the Gross-Up Payment,
Executive shall be deemed to pay Federal income taxes at the highest applicable
marginal rate of federal income taxation for the calendar year in which the
Gross-Up Payment is to be made and to pay any applicable state and local income
taxes at the highest applicable marginal rate of taxation for the calendar year
in which the Gross-Up Payment is to be made, net of the maximum reduction in
federal income taxes which could be obtained from the deduction 



                                       2
<PAGE>   3

of such state or local taxes if paid in such year (determined without regard to
limitations on deductions based upon the amount of Executive's adjusted gross
income), and to have otherwise allowable deductions for federal, state and local
income tax purposes at least equal to those disallowed because of the inclusion
of the Gross-Up Payment in Executive's adjusted gross income. To the extent
practicable, any Gross-Up Payment with respect to any Payment shall be paid by
the Company at the time Executive is entitled to receive the Payment and in no
event will any Gross-Up Payment be paid later than five days after the receipt
by Executive of the Accountant's determination. Any determination by the
Accountants shall be binding upon the Company and Executive. As a result of
uncertainty in the application of section 4999 of the Code at the time of the
initial determination by the Accountants hereunder, it is possible that the
Gross-Up Payment made will have been an amount less than the Company should have
paid pursuant to this Section 3.3(a) (the "Underpayment"). In the event that the
Company exhausts its remedies pursuant to Section 3.3(a)(ii) and Executive is
required to make a payment of any Excise Tax, the Underpayment shall be promptly
paid by the Company to or for Executive's benefit; and

                        (iii)   Executive shall notify the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable after Executive is informed in writing of such claim and
shall apprise the Company of the nature of such claim and the date on which such
claim is requested to be paid. Executive shall not pay such claim prior to the
expiration of the 30-day period following the date on which Executive gives such
notice to the Company (or such shorter period ending on the date that any
payment of taxes, interest and/or penalties with respect to such claim is due).
If the Company notifies Executive in writing prior to the expiration of such
period that it desires to contest such claim, Executive shall:

                                (A)     give the Company any information
reasonably requested by the Company relating to such claim;

                                (B)     take such action in connection with
contesting such claim as the Company shall reasonably request in writing from
time to time, including, without limitation, accepting legal representation with
respect to such claim by an attorney reasonably selected by the Company;

                                (C)     cooperate with the Company in good faith
in order to effectively contest such claim; and

                                (D)     permit the Company to participate in any
proceedings relating to such claims;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax or income tax (including interest
and penalties with respect thereto) imposed as a result of such



                                       3
<PAGE>   4

representation and payment of all related costs and expenses. Without limiting
the foregoing provisions of this Section 3.3(a), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forgo any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and Executive agrees to
prosecute such contest to a determination before any administrative tribunal, in
a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine; provided, however, that if the Company directs
Executive to pay such claim and sue for a refund, the Company shall advance the
amount of such payment to Executive, on an interest-free basis, and shall
indemnify Executive for and hold Executive harmless from, on an after-tax basis,
any Excise Tax or income tax (including interest or penalties with respect
thereto) imposed with respect to such advance or with respect to any imputed
income with respect to such advance (including as a result of any forgiveness by
the Company of such advance); provided, further, that any extension of the
statute of limitations relating to the payment of taxes for the taxable year of
Executive with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. Furthermore, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder and Executive shall be entitled to settle or contest,
as the case may be, any other issue raised by the Internal Revenue Service or
any other taxing authority.

        3.4.    Benefits.

                (a)     Medical Insurance. The Company shall provide to
Executive, Executive's spouse and children, at its sole cost, such health,
dental and optical insurance as the Company may from time to time make available
to its other executive employees.

                (b)     Life and Disability Insurance. The Company shall provide
Executive such disability and/or life insurance as the Company in its sole
discretion may from time to time make available to its other executive
employees.

                (c)     Pension Plans, Etc. The Executive shall be entitled to
participate in all pension, 401(k) and other employee plans and benefits
established by the Company on at least the same terms as the Company's other
executive employees.

        3.5.    Method of Payment. The monetary compensation payable and any
benefits due to Executive hereunder may be paid or provided in whole or in part,
from time to time, by the Company and/or its respective subsidiaries and
affiliates, but shall at all times remain the responsibility of the Company.

        4.1.    Position. Executive shall serve as Senior Vice President and
Director of Construction and Capital Improvements. The Company agrees that the

the offices of Senior Vice President and Director of Construction and Capital
Improvements. Executive shall have such Executive power and authority as shall
reasonably be required to enable Executive to discharge the duties of such
offices. Executive may, at Executive's discretion, serve the Company and/or its

duties hereunder.

        4.3.    Other Activities. Executive may engage in other activities for

entitled to three (3) weeks vacation per year. During such vacation periods,
Executive shall not be relieved of Executive's duties under this Agreement and
there will be no abatement or reduction of Executive's compensation hereunder.

        4.5.    Business Expenses. The Company shall promptly, but in no event

Executive for all reasonable business expenses including, without limitation,

dispositions of assets, service agreements and registration statements or other
state or federal filings or disclosures, reasonably necessary for Executive to
carry out Executive's duties and responsibilities hereunder. In addition, the
Company agrees to provide Executive, as a condition to Executive's services
hereunder, such staff, equipment and office space as is reasonably necessary for
Executive to perform Executive's duties hereunder.

5.      TERMINATION

        5.1.    By The Company Without Cause. The Company may terminate this
Agreement without "cause" (as hereinafter defined) at any time following the
Effective Date, provided that the Company first delivers to Executive the
Company's written election to terminate this Agreement at least 90 days prior to
the effective date of termination.

        5.2.    Severance Payment.

                (a)     Amount. In the event the Company terminates Executive's
services hereunder pursuant to Section 5.1, Executive shall continue to render
services to the Company pursuant to this Agreement until the date of termination
and shall continue to receive compensation, as provided hereunder, through the
termination date. In addition to other compensation payable to Executive for
services rendered through the termination date, the Company shall pay Executive
no later than the date of such termination, as a single severance payment, an
amount equal to the sum of: (i) two times Executive's average annual Base
Compensation paid hereunder for the preceding thirty-six month period (or, if
Executive has been employed less than thirty-six months, the average annual Base
Compensation for the period employed) plus (ii) an amount equal to two times the
highest annual bonus received by Executive during the preceding thirty-six month
period (or during the period Executive has been employed hereunder if shorter
than thirty-six months) (collectively, the "Severance Amount"). In addition to
payment of the Severance Amount, any unvested stock options or restricted stock
held by Executive shall become fully vested as of the date of termination.

                (b)     Benefits. In the event Executive's employment hereunder
is terminated by the Company without cause pursuant to Section 5.1 or by
Executive pursuant to Section 5.4 or 5.6, then in addition to paying Executive
the Severance Amount and providing for the full vesting of unvested stock
options or restricted stock held by Executive, the Company shall continue to
provide to Executive and Executive's spouse and children, as applicable, all of
the benefits described in Section 3.3 for a period of two years commencing on
the date of such termination (the "Severance Benefits").

        5.3.    By The Company For Cause. The Company may terminate Executive
for cause at any time, upon written notice to Executive. For purposes of this
Agreement, "cause" shall mean:

                (a)     Executive's conviction for commission of a felony or a
crime involving moral turpitude;


                                       6
<PAGE>   7

                (b)     Executive's willful commission of any act of theft,
embezzlement or misappropriation against the Company which, in any such case, is
materially and demonstrably injurious to the Company;

                (c)     Executive's willful and continued failure to
substantially perform Executive's duties hereunder (other than such failure
resulting from Executive's incapacity due to physical or mental illness), which
failure is not remedied within a reasonable time after written demand for
substantial performance is delivered by the Company which specifically
identifies the manner in which the Company believes that Executive has not
substantially performed Executive's duties; or

                (d)     Executive's death or Disability (as hereinafter
defined).

            For purposes of this Section 5.3, no act, or failure to act, on
Executive's part shall be deemed "willful" unless done, or omitted to be done,
by Executive not in good faith.

            In the event Executive is terminated for cause pursuant to this
Section 5.3, Executive shall have the right to receive Executive's compensation
as otherwise provided under this Agreement through the effective date of
termination. Executive shall have no further right to receive compensation or
other consideration from the Company, or have any other remedy whatsoever
against the Company, as a result of this Agreement or the termination of
Executive pursuant to this Section 5.3, except as set forth below with respect
to a termination due to Executive's Disability.

            In the event Executive is terminated by reason of Executive's death
or Disability, the Company shall immediately pay Executive the Severance Amount
and shall continue to provide to provide to Executive's spouse and children, as
applicable, all of the benefits described in Section 3.1 for a period of three
years commencing on the date of such termination. Said payment shall be in
addition to any disability insurance payments to which Executive is otherwise
entitled and any other compensation earned by Executive hereunder. In addition,
any unvested stock options or restricted stock held by Executive shall become
fully vested as of the date of termination. For purposes of this Agreement, the
term "Disability" shall mean a physical or mental incapacity as a result of
which Executive becomes unable to continue the proper performance of Executive's
duties hereunder for six consecutive calendar months or for shorter periods
aggregating 180 business days in any 12 month period, but only to the extent
that such definition does not violate the Americans with Disabilities Act.

        5.4.    By Executive For Good Reason. Executive may terminate this
Agreement for good reason upon at least 10 days prior written notice to the
Company. For purposes of this Agreement, "good reason" shall mean:

                (a)     the Company's material breach of any of its respective
obligations hereunder and either such breach is incurable or, if curable, has
not been cured within fifteen (15) days following receipt of written notice by
Executive to the Company of such breach by the Company;



                                       7
<PAGE>   8

                (b)     any removal of Executive from one or more of the offices
specified in the first sentence of Section 4.1 without cause and without
Executive's prior written consent; or

                (c)     any material decrease in Executive's authority or
responsibilities hereunder without Executive's prior written consent.

            In the event that Executive terminates this Agreement for good
reason pursuant to this Section 5.4, Executive shall have the right to receive
Executive's compensation as provided hereunder through the effective date of
termination and shall also have the same rights and remedies against the Company
as Executive would have had if the Company had terminated Executive's employment
without cause pursuant to Section 5.1 (including the right to receive the
Severance Amount payable and the Severance Benefits to be provided under Section
5.2).

        5.5.    Executive's Voluntary Termination. Executive may, at any time,
terminate this Agreement without good reason upon written notice delivered to
the Company at least ninety (90) days prior to the effective date of
termination. In the event of such voluntary termination of this Agreement by
Executive: (i) Executive shall have the right to receive Executive's
compensation as provided hereunder through the effective date of termination,
and (ii) the Company, on the one hand, and Executive, on the other hand, shall
not have any further right or remedy against one another except as provided in
Sections 6, 7 and 8 hereof which shall remain in full force and effect.

        5.6.    Change in Control. Executive may terminate this Agreement, upon
at least ten (10) days' prior written notice to the Company, at any time within
two (2) years after a "change in control" (as hereinafter defined) of the
Company. In the event Executive terminates this Agreement within one (1) year
after a change in control pursuant to this Section 5.6, (i) Executive shall
continue to render services pursuant hereto and shall continue to receive
compensation, as provided hereunder, through the termination date, (ii) the
Company shall pay Executive no later than the date of such termination, as a
single severance payment, an amount equal to the Severance Amount and (iii)
following such termination, the Company shall provide the Severance Benefits as
required by Section 5.2. For purposes of this Agreement, a "change in control"
shall mean the occurrence of any of the following events:

                (a)     the individuals constituting the Board as of the date of
the Effective Date (the "Incumbent Board") cease for any reason to constitute at
least two-thirds (2/3rds) of the Board; provided, however, that if the election,
or nomination for election by the Company's stockholders, of any new director
was approved by a vote of at least two-thirds (2/3rds) of the Incumbent Board,
such new director shall be considered a member of the Incumbent Board;

                (b)     an acquisition of any voting securities of the Company
(the "Voting Securities") by any "person" (as the term "person" is used for
purposes of Section 13(d) or Section 14(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act")) immediately after which such person has
"beneficial ownership" (within the meaning of Rule 13d-3 promulgated under the
1934 Act) ("Beneficial Ownership") of 20% or more of the combined voting power
of the Company's then outstanding Voting Securities; or



                                       8
<PAGE>   9

                (c)     approval by the stockholders of the Company of:

                        (i)     a merger, consolidation, share exchange or
reorganization involving the Company, unless

                                (A)     the stockholders of the Company,
                immediately before such merger, consolidation, share exchange or
                reorganization, own, directly or indirectly immediately
                following such merger, consolidation, share exchange or
                reorganization, at least 80% of the combined voting power of the
                outstanding voting securities of the corporation that is the
                successor in such merger, consolidation, share exchange or
                reorganization (the "Surviving Company") in substantially the
                same proportion as their ownership of the Voting Securities
                immediately before such merger, consolidation, share exchange or
                reorganization; and

                                (B)     the individuals who were members of the
                Incumbent Board immediately prior to the execution of the
                agreement providing for such merger, consolidation, share
                exchange or reorganization constitute at least two-thirds
                (2/3rds) of the members of the board of directors of the
                Surviving Company;

                        (ii)     a complete liquidation or dissolution of the
Company; or

                        (iii) an agreement for the sale or other disposition of
all or substantially all of the assets of the Company.

                (d)     any Person is or becomes the Beneficial Owner of
securities of the Company representing ten percent (10%) or more of the combined
voting power of the Company's then outstanding securities and (A) the identity
of the Chief Executive Officer of the Company is changed during the period
beginning sixty (60) days before the attainment of the ten percent (10%)
beneficial ownership and ending two (2) years thereafter, or (B) individuals
constituting at least one-third (1/3) of the members of the Board at the
beginning of such period shall leave the Board during the period beginning sixty
(60) days before the attainment of the ten percent (10%) beneficial ownership
and ending two (2) years thereafter.

6.      CONFIDENTIALITY

        During the term of Executive's employment under this Agreement,
Executive will have access to and become acquainted with various information
relating to the Company's business operations, marketing data, business plans,
strategies, employees, contracts, financial records and accounts, projections
and budgets, and similar information. Executive agrees that to the extent such
information is not generally available to the public and gives the Company an
advantage over competitors who do not know of or use such information, such
information and documents constitute "trade secrets" of the Company. Executive
further agrees that all such information and documents relating to the business
of the Company, whether they are prepared by Executive or come into Executive's
possession in any other way, are owned by the Company and shall remain the
exclusive property of the Company. Executive shall not misuse, misappropriate or
disclose 



                                       9
<PAGE>   10

any trade secrets of the Company, directly or indirectly, or use them for
Executive's own benefit, either during the term of this Agreement or at any time
thereafter, except as may be necessary or appropriate in the course of
Executive's employment with the Company, unless such action is either previously

                                 PROMISSORY NOTE


$1,000,000.00                                         Beverly Hills, California
                                                                August 14, 1998


               FOR VALUE RECEIVED, the undersigned, Diana M. Laing (the
"Borrower") promises to pay to Arden Realty, Inc., a Maryland Corporation, (the
"Company"), or order, the principal amount of one million dollars ($1,000,000)
with interest from the date hereof on the unpaid principal balance under this
Note at the rate of six percent (6%) per annum (on the basis of a 365-day year
and the actual number of days elapsed). The principal amount of this Note shall
be due and payable on or before the earlier of six years from the date of this
Note, or the date on which the indebtedness under this Note is accelerated as
provided for under this Note or the Pledge Agreement (as defined below). All
accrued and unpaid interest under this Note shall be due and payable
concurrently with principal.

               All payments under this Note shall be made to the Company or its
order, in lawful money of the United States of America at the offices of the
Company at its then principal place of business or at such other place as the
Company or any holder hereof shall designate for such purpose from time to time.

               Each payment under this Note shall be applied in the following
order: (i) to the payment of costs and expenses provided for under this Note or
the Pledge Agreement; (ii) to the payment of accrued and unpaid interest; and
(iii) to the payment of outstanding principal. The Company and each holder
hereof shall have the continuing and exclusive right to apply or reverse and
reapply any and all payments under this Note.

<PAGE>   2

               This note may be prepaid in whole or in part at any time, after
five (5) days written notice of Borrower's intention to make any such
prepayment, which notice shall specify the date and amount of such prepayment.
Any prepayment shall be without penalty except that interest shall be paid to
the date of payment on the principal amount prepaid. After any partial
prepayment hereunder, interest shall be computed on the principal balance due
after deducting the principal portion of such prepayment. Any such partial
prepayment shall be applied against the principal due at maturity and not
against any amount forgiven pursuant to the next paragraph.

               Provided that Borrower is employed by the Company as of the
following anniversary dates hereof, the outstanding principal amount of this
Note set forth opposite such anniversary below shall be forgiven, and Borrower
shall have no obligation to repay such principal amount under this Note as
follows:

</TABLE>

               Notwithstanding the forgiveness of principal set forth in the
previous sentence, Borrower shall be obligated to pay all interest that accrued
on such principal prior to the date it was forgiven.
               
               Provided that Borrower is employed by the Company at the time of
a "change in control" (as hereinafter defined), the entire outstanding principal
amount of this Note as of the date of such "change in control" as well as all
interest on such principal that accrued prior to such "change in control," shall
be forgiven, and Borrower shall have no obligation to repay such

                                       2
<PAGE>   3

principal amount or accrued interest under this Note. For purposes of this Note,
a "change in control" shall mean the occurrence of any of the following events:

               (a) the individuals constituting the Board of Directors of the
Company (the "Board") as of the date of this Note (the "Incumbent Board") cease
for any reason to constitute at least two-thirds (2/3rds) of the Board;
provided, however, that if the election, or nomination for election by the
Company's stockholders, of any new director was approved by a vote of at least
two-thirds (2/3rds) of the Incumbent Board, such new director shall be
considered a member of the Incumbent Board;

               (b) an acquisition of any voting securities of the Company (the
"Voting Securities") by any "person" (as the term "person" is used for purposes
of Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as
amended (the "1934 Act")) immediately after which such person has "beneficial
ownership" (within the meaning of Rule 13d-3 promulgated under the 1934 Act)
("Beneficial Ownership") of 20% or more of the combined voting power of the
Company's then outstanding Voting Securities; or

               (c) approval by the stockholders of the Company of: 

                      (i) a merger, consolidation, share exchange or 
reorganization involving the Company, unless

                             (A)    the stockholders of the Company, immediately
before such merger, consolidation, share exchange or reorganization, own,
directly or indirectly immediately following such merger, consolidation, share
exchange or reorganization, at least 80% of the combined voting power of the
outstanding voting securities of the corporation that is the successor in such
merger, consolidation, share exchange or reorganization (the "Surviving


                                       3
<PAGE>   4

Company") in substantially the same proportion as their ownership of the Voting
Securities immediately before such merger, consolidation, share exchange or
reorganization; and 

                    (B) the individuals who were members of the Incumbent Board
immediately prior to the execution of the agreement providing for such merger,
consolidation, share exchange or reorganization constitute at least two-thirds
(2/3rds) of the members of the board of directors of the Surviving Company; 

               (ii)  a complete liquidation or dissolution of the Company; or 

               (iii) an agreement for the sale or other disposition of all or 
substantially all of the assets of the Company 

        (d) any Person is or becomes the Beneficial Owner of securities of the
Company representing ten percent (10%) or more of the combined voting power of
the Company's then outstanding securities and (A) the identity of the Chief
Executive Officer of the Company is changed during the period beginning sixty
(60) days before the attainment of the ten percent (10%) beneficial ownership
and ending two (2) years thereafter, or (B) individuals constituting at least
one-third (1/3) of the members of the Board at the beginning of such period
shall leave the Board during the period beginning sixty (60) days before the
attainment of the ten percent (10%) beneficial ownership and ending two (2)
years thereafter. 

        Upon the occurrence of a default under this Note or the Pledge
Agreement, including, without limitation, failure to make any principal or
interest payment by the stated maturity (whether by acceleration, notice of
prepayment or otherwise) for such payment, interest shall thereafter accrue on
the entire unpaid principal balance under this Note, including without
limitation any delinquent interest which has been added to the principal amount
due under this Note pursuant to the terms hereof, at the rate set forth herein
plus one percent (1%) per annum 

                                       4
<PAGE>   5

(on the basis of a 365-day year and the actual number of days elapsed). In
addition, upon the occurrence of a default under this Note or the Pledge
Agreement the holder of this Note may, at its option, without notice to or
demand upon Borrower or any other party, declare immediately due and payable the
entire principal balance hereof together with all accrued and unpaid interest
thereon, plus any other amounts then owing pursuant to this Note or the Pledge
Agreement, whereupon the same shall be immediately due and payable. On each
anniversary of the date of any default under this Note and while such default is
continuing, all interest which has become payable and is then delinquent shall,
without curing the default under this Note by reason of such delinquency, be
added to the principal amount due under this Note, and shall thereafter bear
interest at the same rate as is applicable to principal, with interest on
overdue interest to bear interest, in each case to the fullest extent permitted
by applicable law, both before and after default, maturity, foreclosure,
judgment and the filing of any petition in a bankruptcy proceeding.
Notwithstanding anything in this Note to the contrary, in no event shall
interest be charged under this Note which would violate any applicable law, and
if the interest set forth in this Note would violate any law it shall be reduced
to an amount which would not violate any law. 

        This Note is secured under that certain Pledge Agreement, dated as of
August 14, 1998, by and between Borrower and the Company (as amended from time
to time, the "Pledge Agreement"). Reference is hereby made to the Pledge
Agreement for a description of the nature and extent of the security for this
Note and the rights with respect to such security of the holder of this Note.
Nothing herein shall be deemed to limit the rights of the Company under this
Note or the Pledge Agreement, all of which rights and remedies are cumulative.

        No waiver or modification of any of the terms of this Note shall be
valid or binding unless set forth in a writing specifically referring to this
Note and signed by a duly


                                       5
<PAGE>   6
authorized officer of the Company or any holder of this Note, and then only to
the extent specifically set forth therein.

        If any default occurs in any payment due under this Note, Borrower and
all guarantors and endorsers hereof, and their successors and assigns, promise
to pay and expenses, including attorneys' fees, incurred by each holder hereof
in collecting or attempting to collect the indebtedness under this Note, whether
or not any action or proceeding is commenced. None of the provisions hereof and
none of the holder's rights or remedies under this Note on account of any past
or future defaults shall be deemed to have been waived by the holder's
acceptance of any past due payments or by any indulgence granted by the holder
to Borrower.

        Notwithstanding anything to the contrary herein, if Borrower's
employment with the Company shall be terminated for any reason other than for
death or "disability" (as hereinafter defined), the outstanding principal and
accrued but unpaid interest under this Note shall become immediately due and
payable; provided, however, that if the Borrower's employment with the Company
is terminated by reason of her retirement (as determined in the sole discretion
of the Company) and immediately prior to such termination the Borrower is an
insider (as that term is interpreted in the application of the Company's Insider
Trading Policy), the terms of this Note shall remain in full force and effect
notwithstanding such termination. If Borrower's employment with the Company
shall be terminated for death or "disability," the entire outstanding principal
amount of this Note as of the date of such termination, as well as all interest
on such principal that accrued prior to such date, shall be forgiven, and
Borrower shall have no obligation to repay such principal amount or accrued
interest under this Note. For purposes of this Note, "disability" shall mean
shall mean a physical or mental incapacity as a result of which Borrower becomes
unable to continue the proper performance of Borrower's


                                       6
<PAGE>   7

duties for six consecutive calendar months or for shorter periods
aggregating 180 business days in any 12 month period under any employment
agreement which she has entered into with the Company, but only to the extent
that such definition does not violate the Americans with Disabilities Act.

        Borrower and all guarantors and endorsers hereof, and their successors
and assigns, hereby waive presentment, demand, diligence, protest and notice of
every kind (except such notices as may be required under the Pledge Agreement),
and agree that they shall remain liable for all amounts due under this Note
notwithstanding any extension of time or change in the terms of payment of this
Note granted by any holder hereof, any change, alteration or release of any
property now or hereafter securing the payment hereof or any delay or failure by
the holder hereof to exercise any rights under this Note or the Pledge
Agreement. Borrower and all guarantors and endorsers hereof, and their
successors and assigns, hereby waive the right to plead any and all statutes of
limitation as a defense to a demand under this Note to the full extent permitted
by law.

        This Note shall inure to the benefit of the Company, its successors and
assigns and shall bind the heirs, executors, administrators, successors and
assigns of Borrower. Each reference herein to powers or rights of the Company
shall also be deemed a reference to the same power or right of such assignees,
to the extent of the interest assigned to them.

        In the event that any one or more provisions of this Note shall be held
to be illegal, invalid or otherwise unenforceable, the same shall not affect any
other provision of this Note and the remaining provisions of this Note shall
remain in full force and effect. 

        This Note shall be governed by and construed in accordance with the laws
of the State of California, without giving effect to the principles thereof
relating to conflicts of law.

        IN WITNESS WHEREOF, Borrower has caused this Note to be duly executed as

                  (i)   a merger, consolidation, share exchange or

                        (A)   the stockholders of the Company, immediately
before such merger, consolidation, share exchange or reorganization, own,

reorganization; and

                        (B)   the individuals who were members of the Incumbent

(60) days before the attainment of the ten percent (10%) beneficial ownership
and ending two (2) years thereafter, or (B) individuals constituting at least
one-third (1/3) of the members of the Board at the beginning of such period

            Upon the occurrence of a default under this Note or the Pledge
Agreement, including, without limitation, failure to make any principal or
interest payment by the stated maturity (whether by acceleration, notice of
prepayment or otherwise) for such payment, interest shall thereafter accrue on
the entire unpaid principal balance under this Note, including without 


                                       4
<PAGE>   5
Note pursuant to the terms hereof, at the rate set forth herein plus one percent
(1%) per annum (on the basis of a 365-day year and the actual number of days
elapsed). In addition, upon the occurrence of a default under this Note or the
Pledge Agreement the holder of this Note may, at its option, without notice to
or demand upon Borrower or any other party, declare immediately due and payable
the entire principal balance hereof together with all accrued and unpaid
interest thereon, plus any other amounts then owing pursuant to this Note or the
Pledge Agreement, whereupon the same shall be immediately due and payable. On
each anniversary of the date of any default under this Note and while such
default is continuing, all interest which has become payable and is then
delinquent shall, without curing the default under this Note by reason of such
delinquency, be added to the principal amount due under this Note, and shall
thereafter bear interest at the same rate as is applicable to principal, with
interest on overdue interest to bear interest, in each case to the fullest
extent permitted by applicable law, both before and after default, maturity,
foreclosure, judgment and the filing of any petition in a bankruptcy proceeding.
Notwithstanding anything in this Note to the contrary, in no event shall
interest be charged under this Note which would violate any applicable law, and
if the interest set forth in this Note would violate any law it shall be reduced
to an amount which would not violate any law.

            This Note is secured under that certain Pledge Agreement, dated as
of August 14, 1998, by and between Borrower and the Company (as amended from
time to time, the "Pledge Agreement"). Reference is hereby made to the Pledge
Agreement for a description of the nature and extent of the security for this
Note and the rights with respect to such security of the holder of this Note.
Nothing herein shall be deemed to limit the rights of the


                                       5

            Company under this Note or the Pledge Agreement, all of which rights
and remedies are cumulative.

            No waiver or modification of any of the terms of this Note shall be
valid or binding unless set forth in a writing specifically referring to this
Note and signed by a duly authorized officer of the Company or any holder of
this Note, and then only to the extent specifically set forth therein.

            If any default occurs in any payment due under this Note, Borrower
and all guarantors and endorsers hereof, and their successors and assigns,
promise to pay and expenses, including attorneys' fees, incurred by each holder
hereof in collecting or attempting to collect the indebtedness under this Note,
whether or not any action or proceeding is commenced. None of the provisions
hereof and none of the holder's rights or remedies under this Note on account of
any past or future defaults shall be deemed to have been waived by the holder's
acceptance of any past due payments or by any indulgence granted by the holder
to Borrower.

            Notwithstanding anything to the contrary herein, if Borrower's
employment with the Company shall be terminated for any reason other than for
death or "disability" (as hereinafter defined), the outstanding principal and
accrued but unpaid interest under this Note shall become immediately due and
payable; provided, however, that if the Borrower's employment with the Company
is terminated by reason of his retirement (as determined in the sole discretion
of the Company) and immediately prior to such termination the Borrower is an
insider (as that term is interpreted in the application of the Company's Insider
Trading Policy), the terms of this Note shall remain in full force and effect
notwithstanding such termination. If Borrower's employment with the Company
shall be terminated for death or "disability," the 


                                       6
<PAGE>   7
entire outstanding principal amount of this Note as of the date of such
termination, as well as all interest on such principal that accrued prior to
such date, shall be forgiven, and Borrower shall have no obligation to repay
such principal amount or accrued interest under this Note. For purposes of this
Note, "disability" shall mean shall mean a physical or mental incapacity as a
result of which Borrower becomes unable to continue the proper performance of
Borrower's duties for six consecutive calendar months or for shorter periods
aggregating 180 business days in any 12 month period under any employment
agreement which he has entered into with the Company, but only to the extent
that such definition does not violate the Americans with Disabilities Act.

            Borrower and all guarantors and endorsers hereof, and their
successors and assigns, hereby waive presentment, demand, diligence, protest and
notice of every kind (except such notices as may be required under the Pledge
Agreement), and agree that they shall remain liable for all amounts due under
this Note notwithstanding any extension of time or change in the terms of
payment of this Note granted by any holder hereof, any change, alteration or
release of any property now or hereafter securing the payment hereof or any
delay or failure by the holder hereof to exercise any rights under this Note or
the Pledge Agreement. Borrower and all guarantors and endorsers hereof, and
their successors and assigns, hereby waive the right to plead any and all
statutes of limitation as a defense to a demand under this Note to the full
extent permitted by law.

            This Note shall inure to the benefit of the Company, its successors
and assigns and shall bind the heirs, executors, administrators, successors and
assigns of Borrower. Each 


                                       7
<PAGE>   8
reference herein to powers or rights of the Company shall also be deemed a
reference to the same power or right of such assignees, to the extent of the
interest assigned to them.

            In the event that any one or more provisions of this Note shall be
held to be illegal, invalid or otherwise unenforceable, the same shall not
affect any other provision of this Note and the remaining provisions of this
Note shall remain in full force and effect.

            This Note shall be governed by and construed in accordance with the
laws of the State of California, without giving effect to the principles thereof
relating to conflicts of law..

            IN WITNESS WHEREOF, Borrower has caused this Note to be duly
executed as of the day and year first written above.

                                PLEDGE AGREEMENT


            This Pledge Agreement is made and entered into as of August 14,
1998, between Diana M. Laing ("Borrower"), and Arden Realty, Inc., a Maryland
corporation (the "Company").

                                    RECITALS

            A.    The Company has loaned to Borrower $1,000,000.00 as evidenced
by a promissory note dated as of August 14, 1998 (the "Note"), which was used by
Borrower to purchase an aggregate of 42,553 shares of the Company's common stock
(the "Pledged Shares") pursuant to the terms of The 1996 Stock Option and
Incentive Plan of Arden Realty, Inc. and Arden Realty Limited Partnership.

            B.    Borrower desires to grant a security interest in the Pledged
Shares to the Company to secure payment of the Note.

                                    AGREEMENT

            Now, therefore, in consideration of the above recitals and the
mutual covenants hereinafter set forth, the parties hereto agree as follows:

            1.    Creation of Security Interest. Borrower hereby grants to the
Company a security interest in all of Borrower's right, title and interest in
and to the collateral described in section 2 hereinbelow (the "Collateral") in
order to secure the payment and performance of the obligations described in
section 3 hereinbelow.

            2.    Collateral. The Collateral under this Pledge Agreement is:

                  (a)   The Pledged Shares;

                  (b)   All securities, certificates and instruments
      representing or evidencing ownership of the Collateral hereunder, and all
      proceeds and products of any 


<PAGE>   2
      Collateral hereunder, including without limitation, stock, cash, property
      or other dividends, securities, rights and other property now or hereafter
      at any time or from time to time received, receivable or otherwise
      distributed or distributable in respect of or in exchange for any or all
      of such Collateral; and

                  (c)   Any substituted or additional Collateral required to be
      supplied under the terms of this Pledge Agreement.

            3.    Secured Obligations of Borrower. The Collateral secures and
shall hereafter secure the payment to the Company of all indebtedness now or
hereafter owed to the Company by Borrower pursuant to the Note, this Agreement
and any extensions, modifications and renewals thereof.

            4.    Borrower's Representations and Warranties. Borrower represents
and warrants:

                  (a)   Borrower is (or to the extent that this Pledge Agreement
      states that the Collateral is to be acquired after the date hereof, will
      be) the sole owner of the Collateral; that the security interest hereunder
      in the Collateral is a first, prior and perfected security interest; that
      there are no security interests, liens or encumbrances upon, or adverse
      claims of title to, or any other interest whatsoever in, the Collateral or
      any portion thereof except that created by this Pledge Agreement; and that
      no financing statement covering the Collateral or any portion thereof
      exists or is on file in any public office; and

                  (b)   Borrower has full right, power and authority to enter
      into this Pledge Agreement and no consent of, or registration or filing
      with, any person or entity, 


                                       2
<PAGE>   3
      including the California Corporations Commissioner or any other
      governmental officer or entity, is required.

            5.    Covenants of Borrower. Borrower covenants that:

                  (a)   Borrower will deliver to the Company each item of
      Collateral hereunder immediately upon Borrower's acquisition thereof, and
      will defend the Collateral against all claims and demands of all persons
      at any time claiming the same or any interest therein; and

                  (b)   If, while this Pledge Agreement is in effect, any stock
      dividend, stock split, reclassification, readjustment, reorganization,
      merger, consolidation or other change in the capital structure is declared
      or made, or proposed to be declared or made, by the Company or any issuer
      of the Collateral, all substituted and additional securities issued with
      respect to the Collateral shall be endorsed in blank by Borrower promptly
      upon receipt thereof or otherwise appropriately transferred to the Company
      in negotiable form, and all certificates or instruments evidencing such
      securities shall be delivered to the Company to be held under the terms of
      this Pledge Agreement in the same manner as and as part of the Collateral.
      Borrower shall have the right to exercise any subscription or other rights
      with respect to any Collateral, with the prior written approval of such
      exercise by the Company; provided, however, that any securities which may
      be issued upon exercise of any such rights shall be delivered to the
      Company, with any necessary stock power, endorsed in blank and with
      signatures guaranteed, to be included in the Collateral.

            6.    Defaults and Remedies.

                  (a)   The occurrence of any one or more of the following
      events or conditions affecting Borrower shall constitute a default under
      this Pledge Agreement:

                        (i)   Borrower fails to pay any indebtedness, perform
            any obligation required to be performed by her, or discharge her
            liability to the Company in accordance with the terms of the Note;
            or

                        (ii)  Borrower fails to perform any obligation under
            this Agreement.

                  (b)   Upon the occurrence of a default hereunder, the Company
      may, at its option, without notice to or demand upon Borrower, do any one
      or more of the following:

                        (i)   Exercise any or all of the rights and remedies
            provided for by the applicable Uniform Commercial Code, specifically
            including, without limitation, the right to recover the attorneys'
            fees incurred by the Company in the enforcement of this Pledge
            Agreement or in connection with Borrower's redemption of the
            Collateral;

                        (ii)  Sell the Collateral, or any portion thereof, at
            any public or private sale or on any securities exchange or other
            recognized market, for cash, upon credit or for future delivery, as
            the Company shall deem appropriate;

                        (iii) Enforce one or more remedies hereunder,
            successively or concurrently, and such action shall not operate to
            estop or prevent the Company from pursuing any other or further
            remedy it may have, and any repossession or retaking or sale of the
            Collateral pursuant to the terms hereof shall not operate to 


                                       4
<PAGE>   5
            release Borrower until full payment of any deficiency has been made
            in cash. Borrower shall reimburse the Company upon demand for, or
            the Company may apply any proceeds of Collateral to, the costs and
            expenses (including attorneys' fees, transfer taxes and other
            charges) incurred by the Company in connection with any sale,
            disposition or retention of any Collateral hereunder.

            7.    Miscellaneous Provisions.

                  (b)   Headings. The various headings in this Pledge Agreement
      are inserted for convenience only and shall not affect the meaning or
      interpretation of this Pledge Agreement or any provision hereof.

                  (c)   Choice of Law. This Pledge Agreement shall be construed
      in accordance with and all disputes hereunder shall be governed by the
      laws of the State of California, without giving effect to the conflicts of
      law principals thereof.

                  (d)   Amendments. This Pledge Agreement or any provision
      hereof may be changed, waived, or terminated only by a statement in
      writing signed by the party against which such change, waiver or
      termination is sought to be enforced.

                  (e)   No Waiver. No delay in enforcing or failure to enforce
      any right under this Pledge Agreement by the Company shall constitute a
      waiver by the Company of such right. No waiver by the Company of any
      default hereunder shall be effective unless in writing, nor shall any
      waiver operate as a waiver of any other default or of the same default on
      a future occasion.

                  (f)   Time of the Essence. Time is of the essence of each
      provision of this Pledge Agreement of which time is an element.

                  (g)   Binding Agreement. All rights of the Company hereunder
      shall inure to the benefit of its successors and assigns. Borrower shall
      not assign any of its interest under this Pledge Agreement without the
      prior written consent of the Company. Any purported assignment
      inconsistent with this provision shall, at the option of the Company, be
      null and void.


                                       6
<PAGE>   7
                  (h)   Definitions. All terms not defined herein shall have the
      meaning set forth in the applicable Uniform Commercial Code, except where
      the context otherwise requires.

                  (i)   Entire Agreement. This Pledge Agreement, together with
      any other agreement executed in connection herewith, is intended by the
      parties as a final expression of their agreement and is intended as a
      complete and exclusive statement of the terms and conditions thereof.
      Acceptance of or acquiescence in a course of performance rendered under
      this Pledge Agreement shall not be relevant to determine the meaning of
      this Pledge Agreement even though the accepting or acquiescing party had
      knowledge of the nature of the performance and opportunity for objection.

                  (j)   Attorneys' Fees. If any legal action, arbitration or
      other proceeding, is brought for the enforcement of this Pledge Agreement,
      or because of an alleged dispute, breach or default in connection with any
      of the provisions of this Pledge Agreement, each of the parties hereto
      shall be responsible for payment of any attorneys' fees and other costs
      incurred by them in that action or proceeding, without regard to whomever
      is the prevailing party in such action or proceeding.

                  (k)   Severability. If any provision of this Pledge Agreement
      should be found to be invalid or unenforceable, all of the other
      provisions shall nonetheless remain in full force and effect to the
      maximum extent permitted by law.

                  (l)   Power of Attorney. Borrower hereby appoints and
      constitutes the Company as Borrower's attorney-in-fact for purposes of (i)
      collecting any Collateral, and (ii) conveying any item of Collateral to
      any purchaser thereof. This power of attorney is coupled with an interest
      and is irrevocable by Borrower. Notwithstanding the foregoing, 


                                       7
<PAGE>   8
      the Company agrees that it shall not exercise its power of attorney
      granted under this Section 7(l) unless and until there is a default under
      this Pledge Agreement.

                  (m)   Counterparts. This Pledge Agreement may be executed in
      one or more counterparts, each of which shall be deemed an original but
      all of which shall together constitute one and the same agreement.

                  (n)   Termination of Pledge. This Pledge Agreement and the
      security interest and pledge hereunder shall not terminate until the full
      and final payment and performance of all indebtedness and obligations
      secured hereunder. At such time, the Company shall reassign and deliver to
      Borrower all of the Collateral hereunder which has not been sold, disposed
      of, retained or applied by the Company in accordance with the terms
      hereof. Such reassignment and redelivery shall be without warranty by or
      recourse to the Company, and shall be at the expense of Borrower. Without
      limiting the generality of the foregoing, the security interest and pledge
      hereunder shall not be terminated by the transfer of any of the Collateral
      hereunder from the Company to Borrower, or any person designated by
      Borrower, for the purpose of ultimate sale, exchange, presentation,
      collection, renewal or registration of transfer or for any other purpose.

                  (o)   Release of Collateral. Borrower shall be permitted to
      sell any of the shares of Collateral and the Company shall release such
      shares from Borrower's pledge hereunder provided, however, that (i) so
      long as Borrower has not sold more than the aggregate shares of common
      stock of the Company beneficially owned by Borrower on or after the
      employment anniversary dates as specified below, (or the Company has

                                PLEDGE AGREEMENT


            This Pledge Agreement is made and entered into as of August 14,
1998, between Andrew J. Sobel ("Borrower"), and Arden Realty, Inc., a Maryland
corporation (the "Company").

                                    RECITALS

            A.    The Company has loaned to Borrower $1,000,000.00 as evidenced
by a promissory note dated as of August 14, 1998 (the "Note"), which was used by
Borrower to purchase an aggregate of 42,553 shares of the Company's common stock
(the "Pledged Shares") pursuant to the terms of The 1996 Stock Option and
Incentive Plan of Arden Realty, Inc. and Arden Realty Limited Partnership.

            B.    Borrower desires to grant a security interest in the Pledged
Shares to the Company to secure payment of the Note.

                                    AGREEMENT

            Now, therefore, in consideration of the above recitals and the
mutual covenants hereinafter set forth, the parties hereto agree as follows:

            1.    Creation of Security Interest. Borrower hereby grants to the
Company a security interest in all of Borrower's right, title and interest in
and to the collateral described in section 2 hereinbelow (the "Collateral") in
order to secure the payment and performance of the obligations described in
section 3 hereinbelow.

            2.    Collateral. The Collateral under this Pledge Agreement is:

                  (a)   The Pledged Shares;


<PAGE>   2
                  (b)   All securities, certificates and instruments
      representing or evidencing ownership of the Collateral hereunder, and all
      proceeds and products of any Collateral hereunder, including without
      limitation, stock, cash, property or other dividends, securities, rights
      and other property now or hereafter at any time or from time to time
      received, receivable or otherwise distributed or distributable in respect
      of or in exchange for any or all of such Collateral; and

                  (c)   Any substituted or additional Collateral required to be
      supplied under the terms of this Pledge Agreement.

            3.    Secured Obligations of Borrower. The Collateral secures and
shall hereafter secure the payment to the Company of all indebtedness now or
hereafter owed to the Company by Borrower pursuant to the Note, this Agreement
and any extensions, modifications and renewals thereof.

            4.    Borrower's Representations and Warranties. Borrower represents
and warrants:

                  (a)   Borrower is (or to the extent that this Pledge Agreement
      states that the Collateral is to be acquired after the date hereof, will
      be) the sole owner of the Collateral; that the security interest hereunder
      in the Collateral is a first, prior and perfected security interest; that
      there are no security interests, liens or encumbrances upon, or adverse
      claims of title to, or any other interest whatsoever in, the Collateral or
      any portion thereof except that created by this Pledge Agreement; and that
      no financing statement covering the Collateral or any portion thereof
      exists or is on file in any public office; and


                                       2
<PAGE>   3
                  (b)   Borrower has full right, power and authority to enter
      into this Pledge Agreement and no consent of, or registration or filing
      with, any person or entity, including the California Corporations
      Commissioner or any other governmental officer or entity, is required.

            5.    Covenants of Borrower. Borrower covenants that:

                  (a)   Borrower will deliver to the Company each item of
      Collateral hereunder immediately upon Borrower's acquisition thereof, and
      will defend the Collateral against all claims and demands of all persons
      at any time claiming the same or any interest therein; and

                  (b)   If, while this Pledge Agreement is in effect, any stock
      dividend, stock split, reclassification, readjustment, reorganization,
      merger, consolidation or other change in the capital structure is declared
      or made, or proposed to be declared or made, by the Company or any issuer
      of the Collateral, all substituted and additional securities issued with
      respect to the Collateral shall be endorsed in blank by Borrower promptly
      upon receipt thereof or otherwise appropriately transferred to the Company
      in negotiable form, and all certificates or instruments evidencing such
      securities shall be delivered to the Company to be held under the terms of
      this Pledge Agreement in the same manner as and as part of the Collateral.
      Borrower shall have the right to exercise any subscription or other rights
      with respect to any Collateral, with the prior written approval of such
      exercise by the Company; provided, however, that any securities which may
      be issued upon exercise of any such rights shall be delivered to the
      Company, with any necessary stock power, endorsed in blank and with
      signatures guaranteed, to be included in the Collateral.

            6.    Defaults and Remedies.

                  (a)   The occurrence of any one or more of the following
      events or conditions affecting Borrower shall constitute a default under
      this Pledge Agreement:

                        (i)   Borrower fails to pay any indebtedness, perform
            any obligation required to be performed by him, or discharge his
            liability to the Company in accordance with the terms of the Note;
            or

                        (ii)  Borrower fails to perform any obligation under
            this Agreement.

                  (b)   Upon the occurrence of a default hereunder, the Company
      may, at its option, without notice to or demand upon Borrower, do any one
      or more of the following:

                        (i)   Exercise any or all of the rights and remedies
            provided for by the applicable Uniform Commercial Code, specifically
            including, without limitation, the right to recover the attorneys'
            fees incurred by the Company in the enforcement of this Pledge
            Agreement or in connection with Borrower's redemption of the
            Collateral;

                        (ii)  Sell the Collateral, or any portion thereof, at
            any public or private sale or on any securities exchange or other
            recognized market, for cash, upon credit or for future delivery, as
            the Company shall deem appropriate;

                        (iii) Enforce one or more remedies hereunder,
            successively or concurrently, and such action shall not operate to
            estop or prevent the Company from pursuing any other or further
            remedy it may have, and any repossession or 


                                       4
<PAGE>   5
            retaking or sale of the Collateral pursuant to the terms hereof
            shall not operate to release Borrower until full payment of any
            deficiency has been made in cash. Borrower shall reimburse the
            Company upon demand for, or the Company may apply any proceeds of
            Collateral to, the costs and expenses (including attorneys' fees,
            transfer taxes and other charges) incurred by the Company in
            connection with any sale, disposition or retention of any Collateral
            hereunder.

                  (b)   Headings. The various headings in this Pledge Agreement
      are inserted for convenience only and shall not affect the meaning or
      interpretation of this Pledge Agreement or any provision hereof.

                  (c)   Choice of Law. This Pledge Agreement shall be construed
      in accordance with and all disputes hereunder shall be governed by the
      laws of the State of California, without giving effect to the conflicts of
      law principals thereof.

                  (d)   Amendments. This Pledge Agreement or any provision
      hereof may be changed, waived, or terminated only by a statement in
      writing signed by the party against which such change, waiver or
      termination is sought to be enforced.

                  (e)   No Waiver. No delay in enforcing or failure to enforce
      any right under this Pledge Agreement by the Company shall constitute a
      waiver by the Company of such right. No waiver by the Company of any
      default hereunder shall be effective unless in writing, nor shall any
      waiver operate as a waiver of any other default or of the same default on
      a future occasion.

                  (f)   Time of the Essence. Time is of the essence of each
      provision of this Pledge Agreement of which time is an element.

                  (g)   Binding Agreement. All rights of the Company hereunder
      shall inure to the benefit of its successors and assigns. Borrower shall
      not assign any of its interest under this Pledge Agreement without the
      prior written consent of the Company. Any purported assignment
      inconsistent with this provision shall, at the option of the Company, be
      null and void.

                  (h)   Definitions. All terms not defined herein shall have the
      meaning set forth in the applicable Uniform Commercial Code, except where
      the context otherwise requires.

                  (i)   Entire Agreement. This Pledge Agreement, together with
      any other agreement executed in connection herewith, is intended by the
      parties as a final expression of their agreement and is intended as a
      complete and exclusive statement of the terms and conditions thereof.
      Acceptance of or acquiescence in a course of performance rendered under
      this Pledge Agreement shall not be relevant to determine the meaning of
      this Pledge Agreement even though the accepting or acquiescing party had
      knowledge of the nature of the performance and opportunity for objection.

                  (j)   Attorneys' Fees. If any legal action, arbitration or
      other proceeding, is brought for the enforcement of this Pledge Agreement,
      or because of an alleged dispute, breach or default in connection with any
      of the provisions of this Pledge Agreement, each of the parties hereto
      shall be responsible for payment of any attorneys' fees and other costs
      incurred by them in that action or proceeding, without regard to whomever
      is the prevailing party in such action or proceeding.

                  (k)   Severability. If any provision of this Pledge Agreement
      should be found to be invalid or unenforceable, all of the other
      provisions shall nonetheless remain in full force and effect to the
      maximum extent permitted by law.

                  (l)   Power of Attorney. Borrower hereby appoints and
      constitutes the Company as Borrower's attorney-in-fact for purposes of (i)
      collecting any Collateral, and (ii) conveying any item of Collateral to
      any purchaser thereof. This power of attorney is coupled with an interest
      and is irrevocable by Borrower. Notwithstanding the foregoing, 


                                       7
<PAGE>   8
      the Company agrees that it shall not exercise its power of attorney
      granted under this Section 7(l) unless and until there is a default under
      this Pledge Agreement.

                  (m)   Counterparts. This Pledge Agreement may be executed in
      one or more counterparts, each of which shall be deemed an original but
      all of which shall together constitute one and the same agreement.

                  (n)   Termination of Pledge. This Pledge Agreement and the
      security interest and pledge hereunder shall not terminate until the full
      and final payment and performance of all indebtedness and obligations
      secured hereunder. At such time, the Company shall reassign and deliver to
      Borrower all of the Collateral hereunder which has not been sold, disposed
      of, retained or applied by the Company in accordance with the terms
      hereof. Such reassignment and redelivery shall be without warranty by or
      recourse to the Company, and shall be at the expense of Borrower. Without
      limiting the generality of the foregoing, the security interest and pledge
      hereunder shall not be terminated by the transfer of any of the Collateral
      hereunder from the Company to Borrower, or any person designated by
      Borrower, for the purpose of ultimate sale, exchange, presentation,
      collection, renewal or registration of transfer or for any other purpose.

                  (o)   Release of Collateral. Borrower shall be permitted to
      sell any of the shares of Collateral and the Company shall release such
      shares from Borrower's pledge hereunder provided, however, that (i) so
      long as Borrower has not sold more than the aggregate shares of common
      stock of the Company beneficially owned by Borrower on or after the
      employment anniversary dates as specified below, (or the Company has
      consented in writing to such a sale prior to such sale):

      security under this or any other agreement for obligations owing by
      Borrower to the Company so sold and provided further, that if as a result
      of any such sale the value of the remaining Collateral would be less than
      the aggregate amount owing under the Note after such repayment plus any
      other obligations of Borrower secured by the Collateral, Borrower shall
      pay to the Company the lesser of (x) all of the net (after-tax) proceeds
      from such sale and (y) as much of the net (after-tax) proceeds of such
      sale as would be required to result in the value of the remaining
      collateral being equal to or greater than the aggregate amount owing under
      the Note after such repayment plus any other obligations of Borrower
      secured by the Collateral and (ii) if Borrower has sold more than the
      aggregate shares of common stock of the Company beneficially owned by
      Borrower permitted to be sold in accordance with the table set forth above
      during any fiscal quarter of the Company, Borrower shall pay to the
      Company all of the net (after-tax) proceeds of the sale of such shares.

            IN WITNESS WHEREOF, the parties hereto have caused this Pledge
Agreement to be duly executed the day and year first above written.
