Re:      Offer Letter/Employment Agreement


Dear Mr. Russell:

It is my pleasure to offer you an executive management position with PS Business
Parks,  Inc.  (PSBP)  effective  on  a  mutually  agreed  upon  date,  currently
anticipated to be September 23, 2002, but no later than September 30, 2002. This
offer is for the  position  of  President  located in our  Glendale,  California
office.  We  think  it is  essential  that  the  terms  and  conditions  of your
employment be set forth clearly and completely in one place. That is the purpose
of this letter.

POSITION:
- --------
You will work as President.  In this position,  you will initially report to Ron
Havner,  Chairman of the Board of Directors and CEO. Your  responsibilities,  to
which you will devote your full-time efforts,  will include the oversight of the
Company's  property  operations,   assist  in  the  formulation  of  operational
strategy,  capital  allocation and risk  management  strategies and be primarily
responsible  for their  execution in a timely manner that  enhances  shareholder
value. PSBP may change these responsibilities at any time during your employment
by creating new responsibilities and/or removing certain responsibilities.

COMPENSATION:
- ------------
You will be paid twice monthly on the 15th and last day of the month,  at a rate
of $250,000 per year while actively employed by PSBP. Commencing January 1, 2003
of your employment,  you will be eligible to participate in the PSBP Performance
Bonus Plan.  For the calendar year 2003 the current Bonus Plan for your position
contemplates  a "target  bonus" of  $250,000.  For the  period  January  1, 2003
through December 31, 2003, should you remain continuously  actively employed for
that  calendar  year,  you will be paid a minimum  of 75% of your  target  bonus
potential  no  later  than  January  31,  2004.  Payment  of all or  part of the
remaining 25% of the target bonus will be solely within the  discretion of PSBP.
Should you cease  employment  prior to December 31, 2003 for reasons  other than
"cause" or become  disabled for longer than 30 days, your bonus will be prorated
for the period of your active  employment from January 1, 2003 through  December
31, 2003.  Should you cease  employment  prior to December 31, 2003 for "cause,"
you will receive no bonus. Starting in 2004, your bonus, if any, will be subject
to the  Company's  regular bonus plan  provisions in effect at that time,  which
include no minimum payment, payment within sixty days of the subsequent calendar
year and a requirement  to be employed  continuously  during the year and at the
time of payment.

INTERIM BONUS:
- -------------
During the period  between your start date and  December  31, 2002,  you will be
entitled to a maximum bonus of 2,000 shares of PSBP common  stock,  to be issued
solely within the discretion of PSBP.  Such interim bonus,  if awarded,  will be
issued no later than January 31, 2003.



VACATION:
- --------
You will be entitled to three (3) weeks annual paid vacation, earned and accrued
on a pay period basis and prorated over the course of your employment during the
year.  Restrictions on the accrual of vacation benefits are more fully set forth
in the Employee Handbook.

OTHER BENEFITS:
- --------------
PS Business Parks offers a comprehensive  benefits  package to its employees.  A
summary of the benefits package has already been given to you.

MILEAGE REIMBURSEMENT:
- ---------------------
You will be reimbursed for your business mileage at $0.365 per mile (the current
IRS guidelines).  You will be required to track your mileage and provide records
for reimbursement monthly.

EMPLOYEE RETENTION AND REWARDS:
- ------------------------------
As we discussed with you, our goal is to hire,  retain and reward  employees who
exceed  expectations,  contribute to the growth and development of our employees
and contribute to the growth and profitability of the Company. Accordingly, on a
subjective  basis the Company  periodically  awards stock options and restricted
stock to certain employees, which include a variety of vesting periods. You will
be awarded a total of 100,000  stock  options,  which vest at the rate of 20% on
each  anniversary date of your employment with PSBP for a five-year  period.  On
the one year anniversary of your employment with PSBP, you will also be eligible
to participate  in PSBP's  Restricted  Stock Grant Program.  All awards of stock
options and restricted  stock are subject to PSBP's plan  prospectus,  which has
been previously given to you.

TRADE SECRETS AND CONFIDENTIAL INFORMATION:
- ------------------------------------------
Our competitive  success depends on the proper safeguarding of trade secrets and
confidential  information  developed  within  PSBP  or  entrusted  to us by  our
customers.  Some of the  information  we receive  also  touches  on the  privacy
interests of individuals  and must be  safeguarded  for that reason as well. You
promise to preserve the confidentiality of PSBP's trade secrets and commercially
useful  confidential  information learned through your employment at PSBP and to
use all such information only as necessary and appropriate for PSBP's legitimate
business  purposes.  You promise to  safeguard  against  disclosure  without the
consent of affected persons all information touching on the privacy interests of
employees of PSBP or customers or employees of customers. Such trade secrets and
commercially   useful   confidential   information  include  without  limitation
information about benefit plan or program designs,  financial  information about
PSBP or  customers,  the  identity  of PSBP's  present or  potential  customers,
communications  between  PSBP and its present or  potential  customers,  and the
contents of PSBP's business  plans,  its products or its proposals to present or
potential customers.

RELOCATION PAYMENT:
- ------------------
As part of your employment,  PS Business Parks agrees to reimburse you for up to
$100,000 of moving and relocation expenses.  Such reimbursement is predicated on
proper  support  (in the  form  of  receipts  or  invoices)  provided  by you in
connection with your  relocation and shall be adjusted for any adverse  personal
income tax consequences to you. Such  reimbursement  will expire within one year
after this date of this letter. Such reimbursement will be made at least monthly
by the Company upon submission of invoices or other documentation.






EXTRAORDINARY EVENT PAYMENT:
- ---------------------------
In the event of a sale,  merger or  liquidation  of the  Company  or such  other
similar  extraordinary  event  resulting  in the payment of  severance  or other
termination pay to all or substantially all other Senior Officers (persons which
are deemed executive officers for purposes of SEC reporting requirements,  other
than the Chairman and CEO) of equal or lower rank than President,  then employee
will be paid no less than the highest  amount paid to such other Senior  Officer
of equal or lower rank, exclusive of stock options or restricted stock.

EMPLOYMENT TERMINATION:
- ----------------------
You and we agree  that your  employment  is "at  will."  Either  you or PSBP may
terminate  your  employment  at any time with  cause or without  cause,  for any
reason or no reason,  for your convenience or for PSBP's convenience and without
prior notice.

In  the  event  that  either  you  or  PSBP  terminates  your  employment,  your
compensation and any other payments under this Agreement shall end as of the day
following  such  employment  termination,   and  your  entitlement  to  employee
benefits,  if any,  shall be as  exclusively  provided in written  benefit  plan
documents.

Subject to the foregoing, if your employment is terminated prior to December 31,
2003 for any reason  other than  "cause,"  you will be  entitled  to  one-year's
salary up to a maximum of $250,000  and your pro rata share of your bonus target
up through the date of termination, up to a maximum of $187,500.

Termination for "cause" may be based upon any of the following, as determined by
PSBP in its reasonable discretion:

      (i)     Any act of fraud, dishonesty,  embezzlement, defalcation or theft.

      (ii)    Conviction of,  or a plea of nolo contendre to,  any felony or any
              misdemeanor involving moral turpitude;

      (iii)   Any  act   of   gross  negligence   in  the  performance  of  your
              responsibilities,   any  material  breach  of  the   policies  and
              procedures  of  PSBP or an act or conduct which negatively affects
              the profitability  or  morale  of  PSBP, which is not cured within
              fifteen days after notice to cure;

      (iv)    An inexcusable  repeated or prolonged absence from work other than
              as a result of illness or a disability;

      (v)     Any unethical or improper conduct that exposes PSBP to significant
              claims or other liability; or

      (vi)    Your voluntary resignation from employment with PSBP.

In the event that your employment is terminated for cause, PSBP shall pay to you
any unpaid salary and benefits  earned  pursuant to this  agreement  through the
last day of actual employment by PSBP. Additionally,  PSBP will reimburse to you
reasonable and documented  expenses.  PSBP shall have no further  obligations to
you, and you shall have no further rights, including, without limitation, rights
to any bonus, unvested stock options,  other compensation or benefits whatsoever
under this Agreement.

APPLICABLE LAW:

This Agreement shall be governed by and construed in accordance with the laws of
the State of California.

CONSTRUCTION OF TERMS:
- ---------------------
The terms and  provisions  of this  Agreement,  which are freely  negotiated  as
between the parties, shall not be construed either in favor of or against either

MODIFICATIONS:
- -------------
Any  modification  of this  Agreement will be effective only if it is in writing
and signed by all parties to be charged.

WAIVER:
- ------
A waiver of any of the terms and  conditions  hereof shall not be construed as a
general  waiver  of the  same or any  other  term  or  condition  hereof  of any
subsequent breach thereof.

ARBITRATION:
- -----------
Employee, on the one hand, and the Company on the other hand, agree to submit to
final and binding arbitration, and not to any other forum, any claim by Employee
or Company  under state,  federal or local law which arises out of or relates to
Employee's  employment with Company,  including  without  limitation  claims for
sexual harassment,  discrimination,  wrongful  termination,  breach of contract,
invasion of privacy and defamation.



This Agreement excludes  employment-related claims that cannot be required to be
submitted  to  arbitration  under  applicable  law,  such as claims for workers'
compensation or  unemployment  insurance  benefits.  The Agreement also excludes
from  arbitration any claims by Employee or Company as to whether Employee has a
right to occupy living quarters  furnished by Company,  except where the loss of
use of such living quarters is an element of damages  recoverable  under a claim
subject  to  arbitration  under  this  Agreement.   Notwithstanding   any  other
provisions of this Agreement, Employee and Company agree that breaches of either
Employee's  or  the  Company's  obligations   concerning  trade  secrets  and/or
confidential information cannot adequately be remedied at law or in arbitration,
and we agree that either  Employee  or Company  may seek and upon  proper  proof
obtain,  from a court with proper  jurisdiction,  injunctive relief and damages.
Any such injunctive  proceeding shall be without  prejudice to Employee's or the
Company's rights under this Agreement to obtain other relief in arbitration with
respect to such matters.

Arbitration   under  this  Agreement,   including  the  selection  of  a  single
arbitrator,  shall be governed by the most recent  version of the National Rules
for  the  Resolution  of  Employment  Disputes  (the  "Rules")  of the  American
Arbitration Association ("AAA"), except to the extent inconsistent with specific
provisions of this Agreement. State law provisions governing arbitrations in the
state where Employee is employed,  such as provisions for temporary  restraining
orders and preliminary  injunctions,  shall also apply unless  inconsistent with
the AAA Rules or this Agreement.

In order to initiate a claim for arbitration, the party seeking arbitration must
deliver to the local AAA office,  and send to the other party a written  request
for  arbitration  within the time period  required by the statute of  limitation
applicable to the party's claim (the time within which the party's claim must be
filed  according to law).  Contact  information for the nearest AAA office and a
copy of the AAA Rules may be obtained from Company's Human Resources Department.
Arbitration  proceedings shall be held before a single arbitrator in or near the
city or town where Employee's employment services were performed,  at a location
mutually agreed upon by Employee and Company or a location otherwise  determined
by the AAA or the arbitrator.

Each party shall pay his/her or its own attorneys'  fees if the party chooses to
be  represented  by an  attorney,  except where the  arbitrator  orders that the
prevailing  party recover  attorneys' fees from the other party under applicable
law.  In no case,  however,  shall the  Employee  bear any cost or  expense as a
result of  arbitration  that the  Employee  would not be  required to pay if the
claim had been brought in court.

The parties hereto shall be permitted to conduct  discovery as is appropriate to
the  nature of the claim and  necessary  to its full and fair  determination  in
arbitration, including at a minimum access to essential documents and witnesses.
The  arbitrator  shall have the  authority  to order any  appropriate  legal and
equitable  relief  consistent  with that  available to parties in civil  actions
filed in court.

The  decision  of the  arbitrator  shall be in  writing,  and shall  reflect the
arbitrator's  essential  findings and conclusions upon which the award is based.
Such decision  shall be final and binding  subject to review only as provided by
the law of the state in which the  arbitration  took place  governing  review of
arbitration  awards.  If no state law on the subject exists,  the award shall be
subject to the  standard of review  provided in the Federal  Arbitration  Act, 9
U.S.C.  section 10. The award  shall be  enforceable  in any court of  competent
jurisdiction.   Employee  and  Company  agree  that  if  a  court  of  competent
jurisdiction  declares  that any part of this  Agreement is illegal,  invalid or
unenforceable,  this  declaration  will not affect  the  legality,  validity  or
enforceability of the remaining parts of the Agreement, and the illegal, invalid
or unenforceable part will no longer be part of this Agreement.

Employee and Company agree that  arbitration  under this Agreement  shall be the
exclusive means of resolving any claims or disputes arising out of or related to
the  Employee's  employment  with  Company,  which are not resolved  through the
Company's internal grievance  processes or through proceedings before the United
States Equal Employment  Opportunity  Commission (or the state agency processing
charges  of  discrimination),  and are  not  excluded  from  this  Agreement  as
referenced in the second  paragraph  above.  Both parties  further agree that no
proceedings  will be brought by  Employee or Company in any court or other forum
as to any claims covered by this Agreement,  except to enforce this Agreement or
review the  decision  of the  arbitrator  as provided  above.  No claim shall be
arbitrated  that  otherwise  would be barred by the statute of  limitations in a
judicial proceeding.

THIS  AGREEMENT  IS A WAIVER OF ALL RIGHTS TO A CIVIL  COURT  ACTION FOR A CLAIM
ARISING  OUT OF OR RELATED  TO  EMPLOYEE'S  EMPLOYMENT  WITH  COMPANY,  ONLY THE
ARBITRATOR, AND NOT A JUDGE OR JURY, WILL DECIDE THE CLAIM OR DISPUTE.





INTEGRATED COMPLETE AGREEMENT:
- -----------------------------
This Agreement  integrates  and  supersedes all other prior and  contemporaneous
written and oral agreements and  understandings  of every character  between you
and PSBP and comprises  the entire  agreement  between you and PSBP.  Understand
that this Agreement may be amended only by a further express  written  agreement
between  us,  and  cannot  be  amended  by  informal   discussions   or  written
communications from any party. No waiver of any rights or obligations under this
Agreement shall be deemed to have occurred unless in writing signed by the party
against  whom such waiver is asserted  and no waiver shall be deemed a waiver of
any other or subsequent rights or obligations.

We are very excited about the  possibility of you joining us and look forward to
hearing from you. If you should have any questions, please call me.

Sincerely,


/s/  Ronald L. Havner, Jr.
