                        AMENDMENT TO AGREEMENT OF LIMITED
                             PARTNERSHIP RELATING TO
                      8-7/8% SERIES B CUMULATIVE REDEEMABLE
                                 PREFERRED UNITS

                  This  Amendment to the Agreement of Limited  Partnership of PS
Business Parks,  L.P., a California  limited  partnership  (the  "Partnership"),
dated as of April 23, 1999 (this  "Amendment")  amends the  Agreement of Limited
Partnership  of the  Partnership,  dated as of March 17,  1998,  by and among PS
Business Parks,  Inc. (the "General  Partner") and each of the limited  partners
executing a signature page thereto (the  "Partnership  Agreement").  Capitalized
terms used herein and not otherwise  defined shall have the meanings ascribed to
such  terms  in  the  Partnership  Agreement.  Section  references  are  (unless
otherwise specified) references to sections in this Amendment.

                  WHEREAS,   pursuant  to  Section  4.2(a)  of  the  Partnership
Agreement,  the  General  Partner  desires  to cause  the  Partnership  to issue
additional Units of a new class and series,  with the designations,  preferences
and relative, participating, optional or other special rights, powers and duties
set forth herein;

                  WHEREAS,   pursuant  to  Section  4.2(a)  of  the  Partnership
Agreement, the General Partner, without the consent of the Limited Partners, may
amend the Partnership  Agreement by executing a written instrument setting forth
the terms of such amendment; and

                  WHEREAS,  the General  Partner desires by this Amendment to so
amend the Partnership  Agreement as of the date first set forth above to provide
for the designation and issuance of such new class and series of Units.

                  NOW, THEREFORE, the Partnership Agreement is hereby amended by
establishing  and fixing the rights,  limitations and preferences of a new class
and series of Units as follows:

                  Section  1.  Definitions.   Capitalized  terms  not  otherwise
defined herein shall have their respective meanings set forth in the Partnership
Agreement.  Capitalized  terms  that are used in this  Amendment  shall have the
meanings set forth below:

                  (a) "Liquidation Preference" means, with respect to the Series
B Preferred  Units,  $25.00 per Series B Preferred  Unit, plus the amount of any
accumulated and unpaid Priority Return with respect to such unit, whether or not
declared,  minus any  distributions  in excess of the  Priority  Return that has
accrued with respect to such Series B Preferred Units, to the date of payment.

                  (b)  "Parity  Preferred  Units"  means  any class or series of
Partnership Interests of the Partnership now or hereafter authorized,  issued or
outstanding and expressly designated by the Partnership to rank on a parity with
the  Series  B  Preferred  Units  (as  hereinafter   defined)  with  respect  to
distributions and rights upon voluntary or involuntary  liquidation,  winding-up
or dissolution of the Partnership.

                  (c)  "Priority  Return"  means an amount  equal to 8-7/8%  per
annum of the Liquidation  Preference per Series B Preferred Unit,  commencing on
the date of issuance of such Series B Preferred Unit, determined on the basis of
a 365-day  year (and actual days for any period),  cumulative  to the extent not
distributed on any Series B Preferred Unit Distribution Payment Date.

                  (d) "PTP" means a  "publicly  traded  partnership"  within the
meaning of Section 7704 of the Code.

                  Section 2. Designation and Number.  Pursuant to Section 4.2(a)
of the Partnership  Agreement,  a series of Partnership Units in the Partnership
designated as the "8-7/8% Series B Cumulative  Redeemable  Preferred Units" (the
"Series B  Preferred  Units")  is  hereby  established.  The  number of Series B



Preferred Units shall be 510,000.  The Holders of Series B Preferred Units shall
not have any  Percentage  Interest  (as such term is defined in the  Partnership
Agreement) in the Partnership.

                  Section  3.  Distributions.   (a)  Payment  of  Distributions.
Subject to the rights of holders of Parity  Preferred Units as to the payment of
distributions,  pursuant to Section 5.1 of the Partnership Agreement, holders of
Series B Preferred Units shall be entitled to receive,  when, as and if declared
by the Partnership acting through the General Partner, the Priority Return. Such
distributions  shall be  cumulative,  shall  accrue  from the  original  date of
issuance of the Series B Preferred Units and, notwithstanding Section 5.1 of the
Partnership  Agreement,  will be payable (i)  quarterly  in arrears on March 31,
June 30,  September 30 and December 31 of each year commencing on June 30, 1999,
and (ii) in the  event of a  redemption  of  Series B  Preferred  Units  (each a
"Series B  Preferred  Unit  Distribution  Payment  Date").  If any date on which
distributions  are to be made on the Series B Preferred  Units is not a Business
Day (as defined  herein),  then payment of the  distribution  to be made on such
date will be made on the Business Day  immediately  preceding such date with the
same  force and effect as if made on such  date.  Distributions  on the Series B
Preferred  Units will be made to the holders of record of the Series B Preferred
Units on the relevant record dates to be fixed by the Partnership acting through
the General  Partner,  which record dates shall in no event exceed  fifteen (15)
Business Days prior to the relevant Series B Preferred Unit Distribution Payment
Date (the "Series B Preferred Unit Partnership Record Date").

                  (b) Prohibition on Distribution.  No distributions on Series B
Preferred  Units shall be authorized by the General Partner or paid or set apart
for payment by the  Partnership  at any such time as the terms and provisions of
any agreement of the Partnership or the General Partner, including any agreement
relating to their indebtedness, prohibits such authorization, payment or setting
apart for payment or provides that such authorization,  payment or setting apart
for payment would constitute a breach thereof or a default thereunder, or to the
extent that such  authorization  or payment shall be restricted or prohibited by
law.

                  (c)  Distributions  Cumulative.  Distributions on the Series B
Preferred  Units  will  accrue  whether or not the terms and  provisions  of any
agreement  of  the  Partnership,   including  any  agreement   relating  to  its
indebtedness at any time prohibit the current payment of distributions,  whether
or not the  Partnership  has  earnings,  whether or not there are funds  legally
available  for the  payment  of  such  distributions  and  whether  or not  such
distributions are authorized.  Accrued but unpaid  distributions on the Series B
Preferred Units will  accumulate as of the Series B Preferred Unit  Distribution
Payment Date on which they first  become  payable.  Distributions  on account of
arrears for any past distribution  periods may be declared and paid at any time,
without reference to a regular Series B Preferred Unit Distribution Payment Date
to holders of record of the Series B Preferred Units on the record date fixed by
the  Partnership  acting through the General Partner which date shall not exceed
fifteen (15)  Business Days prior to the payment  date.  Accumulated  and unpaid
distributions will not bear interest.

                  (d) Priority as to Distributions. Subject to the provisions of
Article 13 of the Partnership Agreement:

                  (i) so long as any Series B Preferred  Units are  outstanding,
no distribution of cash or other property shall be authorized, declared, paid or
set apart for payment on or with  respect to any class or series of  Partnership
Interest  ranking  junior as to the  payment of  distributions  or rights upon a
voluntary  or  involuntary   liquidation,   dissolution  or  winding-up  of  the
Partnership to the Series B Preferred Units (collectively,  "Junior Units"), nor
shall any cash or other  property  be set aside for or applied to the  purchase,
redemption  or other  acquisition  for  consideration  of any Series B Preferred
Units, any Parity Preferred Units or any Junior Units, unless, in each case, all
distributions  accumulated  on all Series B Preferred  Units and all classes and
series of  outstanding  Parity  Preferred  Units  have  been  paid in full.  The
foregoing sentence shall not prohibit (x) distributions payable solely in Junior
Units,  or (y) the  conversion  of Junior Units or Parity  Preferred  Units into
Partnership Interests ranking junior to the Series B Preferred Units.

                  (ii) So long as distributions have not been paid in full (or a
sum sufficient for such full payment is not  irrevocably  deposited in trust for
payment) upon the Series B Preferred  Units,  all  distributions  authorized and
declared  on the  Series  B  Preferred  Units  and  all  classes  or  series  of
outstanding  Parity Preferred Units shall be authorized and declared so that the
amount of distributions  authorized and declared per Series B Preferred Unit and
such other classes or series of Parity  Preferred  Units shall in all cases bear
to each other the same ratio that accrued  distributions  per Series B Preferred
Unit and such other classes or series of Parity Preferred Units (which shall not



include  any  accumulation  in  respect  of  unpaid   distributions   for  prior
distribution  periods if such class or series of Parity  Preferred  Units do not
have cumulative distribution rights) bear to each other.


                  (e) No Further  Rights.  Holders of Series B  Preferred  Units
shall not be  entitled  to any  distributions,  whether  payable in cash,  other
property or otherwise, in excess of the full cumulative  distributions described
herein.

                  Section  4.  Allocations.  Section  6.1(a) of the  Partnership
Agreement is amended to read, in its entirety, as follows:

                  "(a) General

                  (i) Except as otherwise  set forth in this  Agreement,  Profit
and Loss and items of income, gain, expense, or loss of the Partnership for each
fiscal  year of the  Partnership  shall  be  allocated  among  the  Partners  in
accordance with their respective  Percentage  Interests.  The provisions of this
Section 6.1 shall be amended appropriately in the event that the General Partner
causes the  Partnership to issue Units with different  preferences or redemption
rights.

                  (ii)  Notwithstanding  anything to the  contrary  contained in
this  Agreement,  in any taxable year,  the holders of Series B Preferred  Units
shall be  allocated  an  amount of gross  income  equal to the  Priority  Return
distributed  to such  holders for such taxable  year.  Upon  liquidation  of the
Partnership  or the  interest of the holders of Series B Preferred  Units in the
Partnership,  an amount of Profit,  Loss or items  thereof shall be allocated to
the holders of Series B Preferred Units in a manner such that, immediately prior
to such  liquidation,  the Capital Account  balances of such holders shall equal
the amount of their Liquidation Preference."

                  Section  5.  Optional   Redemption.   (a)  Right  of  Optional
Redemption.  The Series B Preferred Units may not be redeemed prior to the fifth
(5th)  anniversary of the issuance date. On or after such date, the  Partnership
shall have the right to redeem the Series B Preferred  Units,  in whole (and not
in  part),  at any time,  upon not less  than 10 nor more than 60 days'  written
notice,  at a  redemption  price,  payable  in cash,  equal  to the  Liquidation
Preference  (the "Series B Redemption  Price").  The  Redemption  Right given to
Limited  Partners  in  Section  8.6 of the  Partnership  Agreement  shall not be
available to the holders of the Series B Preferred  Units and all  references to
Limited Partners in said Section 8.6 (and related  provisions of the Partnership
Agreement) shall not include holders of the Series B Preferred Units.

                  (a) Procedures for  Redemption.  (i) Notice of redemption will
be (A) faxed,  and (B) mailed by the  Partnership,  by certified  mail,  postage
prepaid,  not less than 10 nor more than 60 days prior to the  redemption  date,
addressed to the respective holders of record of the Series B Preferred Units at
their respective addresses as they appear on the records of the Partnership.  No
failure  to give or defect in such  notice  shall  affect  the  validity  of the
proceedings  for the redemption of any Series B Preferred Units except as to the
holder to whom such  notice was  defective  or not  given.  In  addition  to any
information  required by law, each such notice shall state:  (m) the  redemption
date, (n) the Redemption  Price,  (o) the aggregate number of Series B Preferred
Units to be  redeemed,(p) as provided in Section  5(b)(ii)  below,  the place or
places where evidence of the surrender of such Series B Preferred Units shall be
delivered for payment of the Redemption  Price,  (q) that  distributions  on the
Series B  Preferred  Units to be  redeemed  will  cease  to  accumulate  on such
redemption  date and (r) that payment of the Redemption  Price will be made upon
presentation  of evidence of the  surrender of such Series B Preferred  Units as
set forth in Section 5(b)(ii) below.

                  (ii)  If the  Partnership  gives a  notice  of  redemption  in
respect of Series B Preferred Units (which notice will be irrevocable)  then, by
12:00 noon, New York City time, on the redemption  date,  the  Partnership  will
deliver into escrow with an escrow agent  acceptable to the  Partnership and the
holders of the Series B Preferred  Units (the  "Escrow  Agent")  the  Redemption
Price and an  executed  Redemption  Agreement,  in the form  attached  hereto as
Exhibit A (the  "Redemption  Agreement"),  and an Amendment to the  Agreement of
Limited  Partnership  evidencing the Redemption,  in the form attached hereto as
Exhibit B. The  holders of the Series B Preferred  Units  shall  also,  by 10:00
noon, New York City time, on the redemption  date,  deliver into escrow with the
Escrow Agent an executed  Redemption  Agreement and an executed Amendment to the
Agreement of Limited Partnership evidencing the Redemption. Upon delivery of all
of the  above-described  items by both  parties,  Escrow Agent shall release the
Redemption  Price  to the  holders  of the  Series  B  Preferred  Units  and the
fully-executed  Redemption  Agreement  and  Amendment  to  Agreement  of Limited
Partnership to both parties. On and after the date of redemption,  distributions


will cease to accumulate on the Series B Preferred  Units called for redemption,
unless the Partnership  defaults in the payment  thereof.  If any date fixed for
redemption  of Series B Preferred  Units is not a Business  Day, then payment of
the  Redemption  Price payable on such date will be made on the next  succeeding
day that is a Business Day (and without any interest or other payment in respect
of any such delay)  except that, if such Business Day falls in the next calendar
year,  such payment will be made on the immediately  preceding  Business Day, in
each case  with the same  force  and  effect  as if made on such date  fixed for
redemption. If payment of the Redemption Price is improperly withheld or refused
and not paid by the Partnership,  distributions on such Series B Preferred Units
will continue to  accumulate  from the original  redemption  date to the date of
payment, in which case the actual payment date will be considered the date fixed
for redemption for purposes of calculating the applicable Redemption Price.

                  Section 6. Voting Rights. (a) General. Holders of the Series B
Preferred  Units  will not have any  voting  rights or right to  consent  to any
matter requiring the consent or approval of the Limited Partners,  except as set
forth in  Section  14.1 of the  Partnership  Agreement  and in this  Section  6.
(Solely for purposes of Section 14.1 of the Partnership Agreement, each Series B
Preferred Unit shall be treated as one Partnership Unit.)

                  (b) Certain Voting  Rights.  So long as any Series B Preferred
Units remain  outstanding,  the Partnership  shall not,  without the affirmative
vote of the  holders of at least a  majority  of the  Series B  Preferred  Units
outstanding at the time: (i) authorize or create,  or increase the authorized or
issued amount of, any class or series of Partnership  Interests ranking prior to
the Series B Preferred Units with respect to payment of  distributions or rights
upon  liquidation,  dissolution  or  winding-up or  reclassify  any  Partnership
Interests into any such Partnership Interest, or create,  authorize or issue any
obligations or security convertible into or evidencing the right to purchase any
such Partnership Interests; (ii) designate or create, or increase the authorized
or issued amount of, any Parity  Preferred  Units or reclassify  any  authorized
Partnership Interests into any such Parity Preferred Units, or create, authorize
or issue any obligations or security convertible into or evidencing the right to
purchase any such shares, but only to the extent such Parity Preferred Units are
issued to an Affiliate of the Partnership on terms that differ from the terms of
any  Parity  Preferred  Units  issued  to the  public or  non-Affiliates  of the
Partnership (for purposes of this Section  6(b)(ii),  an issuance to the General
Partner  shall not be treated as an issuance to an Affiliate of the  Partnership
to the  extent  the  issuance  of such  Partnership  Interests  was to allow the
General  Partner to issue  corresponding  preferred stock to persons who are not
Affiliates);  or (iii) either (A) exchange  shares,  consolidate,  merge into or
with, or convey,  transfer or lease its assets  substantially as an entirety to,
any corporation or other entity or (B) amend,  alter or repeal the provisions of
the Partnership Agreement,  whether by merger,  consolidation or otherwise, that
would adversely affect the powers,  special rights,  preferences,  privileges or
voting power of the Series B Preferred Units or the holders  thereof;  provided,
however,  that with  respect  to the  occurrence  of a share  exchange,  merger,
consolidation  or a sale  or  lease  of all of the  Partnership's  assets  as an
entirety,  so long as (1) the Partnership is the surviving entity and the Series
B Preferred Units remain  outstanding with the terms thereof  unchanged,  or (2)
the  resulting,  surviving  or  transferee  entity  is  a  partnership,  limited
liability company or other  pass-through  entity organized under the laws of any
state and  substitutes  the Series B Preferred Units for other interests in such
entity having  substantially the same terms and rights as the Series B Preferred
Units,  including with respect to  distributions,  voting rights and rights upon
liquidation,  dissolution or  winding-up,  then the occurrence of any such event
shall not be deemed to adversely affect such rights, privileges or voting powers
of the holders of the Series B Preferred  Units;  and provided  further that any
increase in the amount of  Partnership  Interests or the creation or issuance of
any other class or series of  Partnership  Interests,  in each case  ranking (y)
junior to the Series B Preferred Units with respect to payment of  distributions
or the distribution of assets upon  liquidation,  dissolution or winding-up,  or
(z) on a parity to the  Series B  Preferred  Units  with  respect  to payment of
distributions  or the  distribution of assets upon  liquidation,  dissolution or
winding-up,  to the  extent  such  Partnership  Interests  are not  issued to an
Affiliate of the  Partnership  (an issuance to the General  partner shall not be
treated as an  issuance to an  Affiliate  of the  Partnership  to the extent the
issuance of such Partnership Interests was to allow the General Partner to issue
corresponding  preferred  stock  to  persons  who  are  not  Affiliates  of  the
Partnership)  such  issuance  shall not be deemed to  materially  and  adversely
affect such rights,  preferences,  privileges or voting powers.  Notwithstanding
anything to the  contrary  contained in this Section 6, if holders of a majority
of the Series B  Preferred  Units do not  approve  of a  proposed  action by the
Partnership  described in clause  (iii) of the  immediately  preceding  sentence
which, in the reasonable judgment of the Partnership,  results in the holders of
Series B Preferred Units having  substantially  the same terms and rights as the
Series B Preferred Units, including with respect to distributions, voting rights
and rights upon  liquidation,  dissolution or  winding-up,  and the holders of a



majority of the Series B Preferred Units do not  affirmatively  vote in favor of
such proposed action, then the Partnership may proceed with such proposed action
and the sole remedy of the holders of the Series B Preferred  Units shall be the
acceleration  of the exchange date relating to the Series B Preferred  Units, as
set forth in Section 8 of this Amendment.  In the event of any conflict  between
the provisions of Section 4.2 of the Partnership Agreement and the provisions of
this Section 6, the provisions of this Section 6 shall control.

                  Section  7.  Transfer  Restrictions.  The  holders of Series B
Preferred  Units shall be subject to all of the  provisions of Section 11 of the
Partnership  Agreement  as modified by this Section 7. Subject to the consent of
the General Partner,  which shall not be unreasonably  withheld or delayed,  the
Series B Preferred Units may be transferred to a maximum of five (5) persons. At
no time shall the number of holders of the Series B Preferred Units exceed five.

                  Section 8. Exchange Rights. (a) Right to Exchange.  (i) Series
B Preferred Units will be exchangeable in whole (and not in part) at any time on
or after the tenth (10th) anniversary of the date of issuance,  at the option of
the Partnership or a majority of the holders  thereof  (acting as a whole),  for
authorized  but  previously  unissued  shares  of  8-7/8%  Series  B  Cumulative
Redeemable  Preferred  Stock of the  General  Partner  (the  "Series B Preferred
Stock") at an  exchange  rate of one share of Series B  Preferred  Stock for one
Series B Preferred Unit, subject to adjustment as described below (the "Series B
Exchange  Price");  provided  that the  Series B  Preferred  Units  will  become
exchangeable  at any  time,  in whole  (and not in  part),  at the  option  of a
majority  of the  holders of Series B  Preferred  Units  (acting as a whole) for
Series B Preferred  Stock if (x) at any time full  distributions  shall not have
been timely made on any Series B  Preferred  Unit with  respect to six (6) prior
quarterly distribution periods, whether or not consecutive;  provided,  however,
that a distribution  in respect of Series B Preferred  Units shall be considered
timely made if made within two (2) Business Days after the  applicable  Series B
Preferred  Units  Distribution  Payment Date if at the time of such late payment
there shall not be any prior quarterly  distribution periods in respect of which
full distributions were not timely made, (y) upon receipt by a holder or holders
of Series B  Preferred  Units of (1) notice from the  General  Partner  that the
General  Partner or a Subsidiary  of the General  Partner has taken the position
that the  Partnership  is,  or upon the  occurrence  of a  defined  event in the
immediate  future  will  be, a PTP and (2) an  opinion  rendered  by an  outside
nationally  recognized  independent counsel familiar with such matters addressed
to a holder or holders of Series B Preferred  Units,  that the Partnership is or
likely is, or upon the  occurrence of a defined  event in the  immediate  future
will be or likely  will be, a PTP,  or (z) the holders of the Series B Preferred
Units hold or will hold 20% or more of the profits and capital  interests of the
Partnership,  provided  further  that,  in the case of clause (z),  the Series B
Preferred Units will be exchangeable  only to the extent necessary to reduce the
holdings of the holders of the Series B Preferred  Units to less than 20% of the
capital  and profits  interests  of the  Partnership.  In addition to and not in
limitation of the foregoing,  the Series B Preferred  Units may be exchanged for
Series B  Preferred  Stock,  in whole  (and not in part),  at the  option of the
holders of a majority of the Series B Preferred  Units (acting as a whole) prior
to the  tenth  (10th)  anniversary  of the  issuance  date and  after  the third
anniversary  thereof if such holder of Series B Preferred Units shall deliver to
the General Partner either (i) a private letter ruling  addressed to such holder
of Series B Preferred Units or (ii) an opinion of independent counsel reasonably
acceptable  to the General  Partner based on the enactment of temporary or final
Treasury  Regulations or the publication of a Revenue Ruling,  in either case to
the effect that an exchange of the Series B Preferred Units at such earlier time
would  not  cause the  Series B  Preferred  Units to be  considered  "stock  and
securities" within the meaning of section 351(e) of the Internal Revenue Code of
1986, as amended (the "Code") for purposes of determining  whether the holder of
such Series B Preferred Units is an "investment company" under section 721(b) of
the Code if an exchange is permitted at such  earlier  date.  In addition to and
not in  limitation  of the  foregoing,  the  Series  B  Preferred  Units  may be
exchanged in whole (and not in part) (regardless of whether held by Contributor)
at the  option of the  holders of a majority  of the  Series B  Preferred  Units
(acting as a whole) for Series B  Preferred  Stock (but only if the  exchange in
whole may be accomplished  consistently with the ownership limitations set forth
under the Article IV of the Charter of the General Partner,  taking into account
exceptions  thereto) if at any time, (i) the  Partnership or the General Partner
breach any of the  covenants  set forth in  Paragraphs  4(d)  through (h) of the
Contribution  Agreement,  dated as of April 23, 1999,  among SSB Tax  Advantaged
Exchange Fund I, LLC  ("Contributor"),  the Partnership and the General Partner,
(ii) the  Partnership  reasonably  determines  that the assets and income of the
Partnership  for a taxable  year  after 1999  would not  satisfy  the income and
assets tests of Section 856 of the Code for such taxable year if the Partnership
were a real estate  investment trust within the meaning of the Code, (iii) under
the circumstances described in the penultimate sentence of Section 6(b), or (iv)
any holder of Series B Preferred  Units shall deliver to the Partnership and the
Company an opinion of independent  counsel reasonably  acceptable to the Company
to the effect  that,  based on the assets  and income of the  Partnership  for a


taxable year after 1999, the Partnership would not satisfy the income and assets
tests of Section 856 of the Code for such taxable year if the Partnership were a
real estate  investment  trust  within the meaning of the Code,  and that in the
case of each of (ii) and (iv),  such failure would create a meaningful risk that
a holder of the Series B Preferred Units would fail to maintain qualification as
a real estate investment trust.

                  (ii)  Notwithstanding  anything to the  contrary  set forth in
Section  8(a)(i),  if an  Exchange  Notice  (as  hereinafter  defined)  has been
delivered to the General  Partner,  then the General Partner may, at its option,
elect to redeem or cause the  Partnership  to redeem all (but not a portion)  of
the  outstanding  Series B  Preferred  Units for cash in an amount  equal to the
Liquidation  Preference  per Series B Preferred  Unit.  The General  Partner may
exercise its option to redeem the Series B Preferred  Units for cash pursuant to
this  Section  8(a)(ii)  by giving  each  holder of record of Series B Preferred
Units notice of its election to redeem for cash,  within five (5) Business  Days
after  receipt of the  Exchange  Notice,  by (m) fax, and (n)  registered  mail,
postage  paid,  at the address of each holder as it may appear on the records of
the Partnership  stating (A) the redemption  date,  which shall be no later than
sixty (60) days following the receipt of the Exchange Notice, (B) the redemption
price,  (C) the place or places  where the  Series B  Preferred  Units are to be
surrendered for payment of the redemption  price, (D) that  distributions on the
Series B Preferred Units will cease to accrue on such redemption  date; (E) that
payment of the redemption price will be made upon  presentation and surrender of
the Series B Preferred Units and (F) the aggregate  number of Series B Preferred
Units to be redeemed.

                  (iii) If an exchange of Series B Preferred  Units  pursuant to
Section  8(a)(i)  would violate the  provisions  on ownership  limitation of the
General  Partner set forth in Article IV of the  Charter of the General  Partner
with respect to the Series B Preferred  Stock,  the General  Partner  shall give
written  notice  thereof to each holder of record of Series B  Preferred  Units,
within five (5) Business Days following  receipt of the Exchange Notice,  by (m)
fax,  and (n)  registered  mail,  postage  prepaid,  at the address of each such
holder set forth in the records of the Partnership.  In such event,  each holder
of Series B  Preferred  Units shall be  entitled  to  exchange,  pursuant to the
provisions  of Section  8(b) a number of Series B  Preferred  Units  which would
comply with the  provisions on the ownership  limitation of the General  Partner
set forth in such  Article IV of the  Charter  of the  General  Partner  and any
Series B Preferred Units not so exchanged (the "Excess Units") shall be redeemed
by the Partnership  for cash in an amount equal to the  Liquidation  Preference.
The written  notice of the General  Partner shall state (A) the number of Excess
Units held by such holder, (B) the redemption price of the Excess Units, (C) the
date on which such Excess Units shall be redeemed,  which date shall be no later
than sixty (60) days following the receipt of the Exchange Notice, (D) the place
or places  where such  Excess  Units are to be  surrendered  for  payment of the
Redemption  Price,  (E) that  distributions  on the  Excess  Units will cease to
accrue on such  redemption  date, and (F) that payment of the  redemption  price
will be made  upon  presentation  and  surrender  of such  Excess  Units.  If an
exchange  would result in Excess Units,  as a condition to such  exchange,  each
holder of such units agrees to provide  representations and covenants reasonably
requested by the General  Partner  relating to (1) the widely held nature of the
interests  in such  holder,  sufficient  to assure the General  Partner that the
holder's ownership of stock of the General Partner (without regard to the limits
described  above)  will not cause any  Person  (as such term is  defined  in the
Charter of the General Partner) to own stock of the General Partner in an amount
that would cause such Person not to comply with the  provisions on the ownership
limitation of the General Partner set forth in such Article IV of the Charter of
the General  Partner;  and (2) to the extent such  holder can so  represent  and
covenant without obtaining  information from its owners,  the holder's ownership
of tenants of the Partnership and its affiliates.


                  (iv) The redemption of Series B Preferred  Units  described in
Section 8(a)(ii) and (iii) shall be subject to the provisions of Section 5(b)(i)
and Section 5(c)(ii);  provided,  however,  that the term "redemption  price" in
such  Section  shall be read to mean the  Liquidation  Preference  per  Series B
Preferred Unit being redeemed.

                  (b)  Procedure  for  Exchange.   (i)  Any  exchange  shall  be
exercised  pursuant to a notice of exchange (the "Exchange Notice") delivered to
the General  Partner by the holder who is exercising such exchange right, by (a)
fax and (b) by  certified  mail  postage  prepaid.  The  exchange  of  Series  B
Preferred  Units may be effected  after the fifth (5th)  Business Day  following
receipt  by  the  General   Partner  of  the  Exchange   Notice  by   delivering
certificates, if any, representing such Series B Preferred Units to be exchanged
together with, if applicable, written notice of exchange and a proper assignment
of such Series B Preferred Units to the office of the General Partner maintained
for such purpose.  Currently,  such office is c/o PS Business  Parks,  Inc., 701
Western Avenue,  Glendale,  California 91201, Attention:  Jack E. Corrigan. Each
exchange will be deemed to have been effected  immediately prior to the close of
business  on the date on which such  Series B  Preferred  Units to be  exchanged
(together  with all  required  documentation)  shall have been  surrendered  and
notice  shall have been  received by the General  Partner as  aforesaid  and the
Exchange  Price  shall  have been  paid.  Any Series B  Preferred  Stock  issued
pursuant  to this  Section  8 shall  be  delivered  as  shares  which  are  duly
authorized, validly issued, fully paid and nonassessable,  free of pledge, lien,
encumbrance or restriction other than those provided in the Charter,  the ByLaws
of the General  Partner,  the  Securities  Act of 1933,  as amended and relevant
state securities or blue sky laws.

                  (ii) In the event of an exchange  of Series B Preferred  Units
for shares of Series B  Preferred  Stock,  an amount  equal to the  accrued  and
unpaid Priority Return,  whether or not declared, to the date of exchange on any
Series B Preferred Units tendered for exchange shall (a) accrue on the shares of
the  Series B  Preferred  Stock into which  such  Series B  Preferred  Units are
exchanged,  and (b) continue to accrue on such Series B Preferred  Units,  which
shall remain  outstanding  following such exchange,  with the General Partner as
the holder of such Series B  Preferred  Units.  Notwithstanding  anything to the
contrary  set forth  herein,  in no event shall a holder of a Series B Preferred
Unit that was validly  exchanged into Series B Preferred  Stock pursuant to this
section  (other  than the General  Partner  now holding  such Series B Preferred
Unit),  receive a  distribution  from the  Partnership,  if such  holder,  after
exchange,  is entitled to receive a distribution  from the General  Partner with
respect  to the  share of Series B  Preferred  Stock  for  which  such  Series B
Preferred Unit was exchanged or redeemed.

                  (iii) Fractional shares of Series B Preferred Stock are not to
be issued upon  exchange but, in lieu  thereof,  the General  Partner will pay a
cash adjustment based upon the fair market value of the Series B Preferred Stock
on the day prior to the exchange  date as  determined in good faith by the Board
of Directors of the General Partner.

                  (c)  Adjustment of Exchange  Price.  (i) The Exchange Price is
subject  to  adjustment  upon  certain  events,   including,  (a)  subdivisions,
combinations  and  reclassification  of the Series B  Preferred  Stock,  and (b)
distributions  to all  holders  of  Series B  Preferred  Stock of  evidences  of
indebtedness  of the  General  Partner  or  assets  (including  securities,  but
excluding  dividends and distributions  paid in cash out of equity applicable to
Series B Preferred Stock).

                  (ii) In case  the  General  Partner  shall  be a party  to any
transaction (including,  without limitation, a merger, consolidation,  statutory
share  exchange,  tender  offer  for  all or  substantially  all of the  General
Partner's  capital  stock  or sale of all or  substantially  all of the  General
Partner's  assets),  in each case as a result of which  the  Series B  Preferred
Stock will be converted into the right to receive shares of capital stock, other
securities or other property (including cash or any combination  thereof),  each
Series B Preferred Unit will thereafter be exchangeable into the kind and amount
of  shares  of  capital  stock  and other  securities  and  property  receivable
(including  cash or any  combination  thereof)  upon  the  consummation  of such
transaction by a holder of that number of shares of Series B Preferred  Stock or
fraction  thereof  into  which  one  Series B  Preferred  Unit was  exchangeable
immediately  prior to such  transaction.  The  General  Partner may not become a
party to any such  transaction  unless the terms thereof are consistent with the
foregoing.  In the event of a conflict  between the  provisions  of this Section
8(c)(ii) and any provision of the Partnership Agreement,  the provisions of this
Section 8(c)(ii) shall control.




                  Section  9. No  Conversion  Rights.  Except  as set  forth  in
Section 8, the holders of the Series B Preferred Units shall not have any rights
to convert  such units into shares of any other class or series of stock or into
any other securities of, or interest in, the Partnership.

                  Section  10.  No  Sinking  Fund.  No  sinking  fund  shall  be
established for the retirement or redemption of Series B Preferred Units.

                  Section 11.  Exhibit A to Partnership  Agreement.  In order to
duly reflect the issuance of the Series B Preferred  Units  provided for herein,
the  Partnership  Agreement is hereby further  amended  pursuant to Section 12.3
thereof by deleting  Exhibit A thereto and replacing  Exhibit A attached  hereto
therefor.

                  Section 12. Inconsistent  Provisions.  Nothing to the contrary
contained  in the  Partnership  Agreement  shall  limit  any of  the  rights  or
obligations set forth in this Amendment.

                  IN WITNESS WHEREOF, this Amendment has been executed as of the
date first above written.

                             PS BUSINESS PARKS, L.P.

                        AMENDMENT TO AGREEMENT OF LIMITED
                            PARTNERSHIP RELATING TO
                       9 1/4% SERIES A CUMULATIVE REDEEMABLE
                                 PREFERRED UNITS

                  This  Amendment to the Agreement of Limited  Partnership of PS
Business Parks,  L.P., a California  limited  partnership  (the  "Partnership"),
dated as of April 30, 1999 (this "Amendment"),  amends the Agreement of Limited
Partnership of the Partnership,  dated as of March 17, 1998, as amended,  by and
among PS Business  Parks,  Inc. (the "General  Partner") and each of the limited
partners described on Exhibit A to that partnership  agreement (the "Partnership
Agreement").  Section references are (unless otherwise specified)  references to
sections in this Amendment.

                  WHEREAS,   the  General  Partner  agreed  to  issue  2,200,000
 Depositary  Shares  each  representing  1/1000th  of a  share  of  the  General
 Partner's preferred stock designated as the "9 1/4% Cumulative Preferred Stock,
 Series A" (the "Depositary Shares") for a price of $25.00 per Depositary Share;

                  WHEREAS,   Section  4.1(b)(2)  of  the  Partnership  Agreement
 requires the General  Partner to contribute to the Partnership the funds raised
 through the issuance of additional  shares of the General Partner in return for
 additional  Partnership  Units, and provides that the General Partner's capital
 contribution  shall be deemed to equal the amount of the gross proceeds of that
 share  issuance  (i.e.,  the  net  proceeds  actually  contributed,   plus  any
 underwriter's  discount or other expenses  incurred,  with any such discount or
 expense deemed to have been incurred on behalf of the Partnership);

                  WHEREAS,  Section 4.2(a) of the Partnership Agreement provides
 generally  for the  creation  and  issuance  of  Partnership  Units  with  such
 designations,  preferences  and  relative,  participating,  optional  or  other
 special rights,  powers and duties,  including rights, powers and duties senior
 to other  Partnership  Interests,  all as shall be  determined  by the  General
 Partner, without the consent of the Limited Partners, and Section 4.2(b) of the
 Partnership  Agreement  specifically  contemplates the issuance of Units to the
 General Partner having  designations,  preferences  and other rights,  all such
 that the economic  interests  are  substantially  similar to the  designations,
 preferences and other rights of shares issued by the General  Partner,  such as
 the Depositary Shares;

                  WHEREAS,  the General Partner desires to cause the Partnership
to issue  additional  Units of a new class and  series,  with the  designations,
preferences  and  relative,  participating,  optional or other  special  rights,
powers and duties set forth herein; and

                  WHEREAS,  the General  Partner desires by this Amendment to so
amend the Partnership  Agreement as of the date first set forth above to provide
for the designation and issuance of such new class and series of Units.

                  NOW, THEREFORE, the Partnership Agreement is hereby amended by
establishing  and fixing the rights,  limitations and preferences of a new class
and series of Units as follows:

                  Section  1.  Definitions.   Capitalized  terms  not  otherwise
defined herein shall have their respective meanings set forth in the Partnership
Agreement.  Capitalized  terms  that are used in this  Amendment  shall have the
meanings set forth below:

                  (a) "Liquidation Preference" means, with respect to the Series
A Preferred Units,  $25.00 per Series A Preferred Unit (as defined below),  plus
the amount of any  accumulated  and unpaid  Priority Return with respect to such
Unit, whether or not declared, minus any distributions in excess of the Priority
Return that has accrued  with respect to such Series A Preferred  Units,  to the
date of payment.

                  (b)  "Parity  Preferred  Units"  means  any class or series of
Partnership Interests of the Partnership now or hereafter authorized,  issued or
outstanding and expressly designated by the Partnership to rank on a parity with
the Series A  Preferred  Units with  respect to  distributions  and rights  upon
voluntary  or  involuntary   liquidation,   winding-up  or  dissolution  of  the
Partnership.  The 8 7/8% Series B Cumulative  Redeemable  Preferred Units of the
Partnership created pursuant to an amendment to the Partnership  Agreement dated
as of April 23, 1999 (the "Series B Preferred Units") and the Series A Preferred
Units are expressly  designated as Parity  Preferred  Units with respect to each
other.


                  (c)  "Priority  Return"  means an  amount  equal to 9 1/4% per
 annum of the Liquidation  Preference per Series A Preferred Unit, commencing on
 the date of issuance of such Series A Preferred  Unit,  determined on the basis
 of a 360-day  year (and twelve  30-day  months),  cumulative  to the extent not
 distributed  on any  Series A  Preferred  Unit  Distribution  Payment  Date (as
 defined below).

                  Section  2.  Creation  of  Series  A  Preferred   Units.   (a)
 Designation  and  Number.   Pursuant  to  Section  4.2(a)  of  the  Partnership
 Agreement,  a series of Partnership Units in the Partnership  designated as the
 "9 1/4%  Series  A  Cumulative  Redeemable  Preferred  Units"  (the  "Series  A
 Preferred  Units") is hereby  established  effective as of April 30, 1999.  The
 number of Series A Preferred Units shall be 2,200,000.  The Holders of Series A
 Preferred Units shall not have any Percentage Interest (as such term is defined
 in the Partnership Agreement) in the Partnership.

                  (b) Capital  Contribution.  In return for the  issuance to the
 General  Partner of the Series A Preferred Units set forth on Exhibit C to this
 Amendment,  the General  Partner has  contributed to the  Partnership the funds
 raised through the General  Partner's  issuance of the  Depositary  Shares (the
 General Partner's capital  contribution  shall be deemed to equal the amount of
 the gross  proceeds of that share  issuance,  i.e.,  the net proceeds  actually
 contributed,  plus any underwriter's discount or other expenses incurred,  with
 any such  discount  or  expense  deemed to have been  incurred  by the  General
 Partner on behalf of the Partnership).

                  (c)  Construction.  The  Series A  Preferred  Units  have been
 created and are being issued in conjunction with the General Partner's issuance
 of the Depositary  Shares  relating to the General  Partner's 9 1/4% Cumulative
 Preferred  Stock,  Series  A, and as such,  the  Series A  Preferred  Units are
 intended to have designations,  preferences and other rights, all such that the
 economic interests are substantially  similar to the designations,  preferences
 and other  rights of the  Depositary  Shares,  and the terms of this  Amendment
 shall be interpreted in a fashion consistent with this intent.

                  Section  3.  Distributions.   (a)  Payment  of  Distributions.
 Subject to the rights of holders of Parity Preferred Units as to the payment of
 distributions, pursuant to Section 5.1 of the Partnership Agreement, holders of
 Series A Preferred Units shall be entitled to receive, when, as and if declared
 by the Partnership  acting through the General  Partner,  the Priority  Return.
 Such distributions shall be cumulative,  shall accrue from the original date of
 issuance of the Series A Preferred  Units and,  notwithstanding  Section 5.1 of
 the  Partnership  Agreement,  will be payable (i) quarterly in arrears on March
 31, June 30,  September 30 and December 31 of each year  commencing on June 30,
 1999, and (ii) in the event of a redemption of Series A Preferred Units (each a
 "Series A Preferred  Unit  Distribution  Payment  Date").  If any date on which
 distributions  are to be made on the Series A Preferred Units is not a Business
 Day (as defined  herein),  then payment of the  distribution to be made on such
 date will be made on the Business Day immediately  preceding such date with the
 same force and effect as if made on such  date.  Distributions  on the Series A
 Preferred Units will be made to the holders of record of the Series A Preferred
 Units on the  relevant  record  dates to be  fixed  by the  Partnership  acting
 through the  General  Partner,  which  record  dates  shall in no event  exceed
 fifteen  (15)  Business  Days prior to the  relevant  Series A  Preferred  Unit
 Distribution Payment Date. Business Day shall be any day other than a Saturday,
 Sunday  or day on which  banking  institutions  in the State of New York or the
 State of California are authorized or obligated by law to close, or a day which
 is or is declared a national or a New York or California state holiday.

                  (b) Prohibition on Distribution.  No distributions on Series A
 Preferred Units shall be authorized by the General Partner or paid or set apart
 for payment by the  Partnership at any such time as the terms and provisions of
 any  agreement  of  the  Partnership  or the  General  Partner,  including  any
 agreement relating to their indebtedness, prohibits such authorization, payment
 or setting  apart for payment or provides that such  authorization,  payment or
 setting  apart for  payment  would  constitute  a breach  thereof  or a default
 thereunder,  or to the  extent  that such  authorization  or  payment  shall be
 restricted or prohibited by law.


                  (c)  Distributions  Cumulative.  Distributions on the Series A
 Preferred  Units will  accrue  whether or not the terms and  provisions  of any
 agreement  of  the  Partnership,   including  any  agreement  relating  to  its
 indebtedness at any time prohibit the current payment of distributions, whether
 or not the  Partnership  has  earnings,  whether or not there are funds legally
 available  for the  payment  of such  distributions  and  whether  or not  such
 distributions are authorized.  Accrued but unpaid distributions on the Series A
 Preferred Units will accumulate as of the Series A Preferred Unit  Distribution
 Payment Date on which they first become  payable.  Distributions  on account of
 arrears for any past distribution periods may be declared and paid at any time,
 without  reference to a regular  Series A Preferred Unit  Distribution  Payment
 Date to holders of record of the Series A  Preferred  Units on the record  date
 fixed by the  Partnership  acting through the General  Partner which date shall
 not exceed  fifteen (15) Business  Days prior to the payment date.  Accumulated
 and unpaid distributions will not bear interest.

                  (d) Priority as to Distributions. Subject to the provisions of
 Article 13 of the Partnership Agreement:

                  (i) So long as any Series A Preferred  Units are  outstanding,
 no distribution of cash or other property shall be authorized,  declared,  paid
 or set  apart  for  payment  on or with  respect  to any  class  or  series  of
 Partnership  Interest  ranking  junior as to the  payment of  distributions  or
 rights upon a voluntary or involuntary  liquidation,  dissolution or winding-up
 of the  Partnership  to the Series A  Preferred  Units  (collectively,  "Junior
 Units"),  nor shall any cash or other  property  be set aside for or applied to
 the purchase, redemption or other acquisition for consideration of any Series A
 Preferred  Units, any Parity  Preferred Units or any Junior Units,  unless,  in
 each case, all  distributions  accumulated on all Series A Preferred  Units and
 all classes and series of outstanding  Parity Preferred Units have been paid in
 full.  The  foregoing  sentence  shall not prohibit (x)  distributions  payable
 solely  in  Junior  Units,  or (y) the  conversion  of  Junior  Units or Parity
 Preferred  Units  into  Partnership  Interests  ranking  junior to the Series A
 Preferred Units.

                  (ii) So long as distributions have not been paid in full (or a
 sum sufficient for such full payment is not irrevocably  deposited in trust for
 payment) upon the Series A Preferred  Units, all  distributions  authorized and
 declared  on the  Series  A  Preferred  Units  and all  classes  or  series  of
 outstanding Parity Preferred Units shall be authorized and declared so that the
 amount of distributions authorized and declared per Series A Preferred Unit and
 such other classes or series of Parity  Preferred Units shall in all cases bear
 to each other the same ratio that accrued  distributions per Series A Preferred
 Unit and such other  classes or series of Parity  Preferred  Units (which shall
 not  include  any  accumulation  in respect of unpaid  distributions  for prior
 distribution  periods if such class or series of Parity  Preferred Units do not
 have cumulative distribution rights) bear to each other.

                  (e) No Further  Rights.  Holders of Series A  Preferred  Units
 shall not be  entitled to any  distributions,  whether  payable in cash,  other
 property or otherwise, in excess of the full cumulative distributions described
 herein.

                  Section 4. Allocations.  Section 6.1(a)(ii) of the Partnership
 Agreement is amended to read, in its entirety, as follows:

                  " (ii)  Notwithstanding  anything to the contrary contained in
 this  Agreement,  in any taxable year, the holders of Series A Preferred  Units
 and Series B Preferred Units shall be allocated an amount of gross income equal
 to the Priority Return distributed to such holders for such taxable year. After
 the Capital Account balances of all Partners other than holders of the Series A
 Preferred  Units have been  reduced  to zero,  losses of the  Partnership  that
 otherwise would be allocated so as to cause deficit  Capital  Account  balances
 for those  other  Partners  shall be  allocated  to the holders of the Series A
 Preferred Units until the Capital Account balances of the holders of the Series
 A  Preferred  Units  have  been  reduced  to  zero.  Upon  liquidation  of  the
 Partnership  or the  interest of the  holders of Series A  Preferred  Units and
 Series B Preferred Units in the Partnership, an amount of Profit, Loss or items
 thereof  shall be  allocated  to the  holders of Series A  Preferred  Units and
 Series B  Preferred  Units in a manner  such  that,  immediately  prior to such
 liquidation,  the  Capital  Account  balances of such  holders  shall equal the
 amount of their Liquidation Preference."

                  Section 5. Optional  Redemption.  The Series A Preferred Units
 shall be redeemed at the same time, to the same extent, and applying, except as
 set forth below,  similar procedures,  as any redemption by the General Partner
 of the Depositary  Shares.  The redemption price,  payable in cash, shall equal
 the  Liquidation  Preference (the  "Redemption  Price").  The Partnership  will
 deliver into escrow with an escrow agent  acceptable to the Partnership and the
 holders of the Series A Preferred Units being redeemed (the "Escrow Agent") the
 Redemption Price and an executed Redemption Agreement, in the substantially the
 form attached as Exhibit A (the  "Redemption  Agreement"),  and an Amendment to
 the  Agreement  of  Limited  Partnership  evidencing  the  Redemption,  in  the
 substantially  the form  attached  as  ExhibitB.  The  holders of the Series A
 Preferred  Units to be redeemed  will also  deliver into escrow with the Escrow
 Agent  an  executed  Redemption  Agreement  and an  executed  Amendment  to the
 Agreement of Limited  Partnership  evidencing the redemption.  Upon delivery of
 all of the  above-described  items by both parties,  on the redemption date the
 Escrow Agent shall release the Redemption  Price to the holders of the Series A
 Preferred Units and the  fully-executed  Redemption  Agreement and Amendment to
 Agreement  of Limited  Partnership  to both  parties.  On and after the date of
 redemption,  distributions  will cease to  accumulate on the Series A Preferred
 Units called for redemption,  unless the Partnership defaults in the payment of
 the Redemption Price. The Redemption Right given to Limited Partners in Section
 8.6 of the  Partnership  Agreement shall not be available to the holders of the
 Series A Preferred Units and all references to Limited Partners in said Section
 8.6 (and related  provisions of the  Partnership  Agreement)  shall not include
 holders of the Series A Preferred Units.

                  Section 6.  Voting  Rights.  Holders of the Series A Preferred
 Units  will not have any  voting  rights  or  right to  consent  to any  matter
 requiring the consent or approval of the Limited Partners,  except as set forth
 in Section 14.1 of the Partnership  Agreement and in this Section 6. Solely for
 purposes of Section 14.1 of the Partnership Agreement,  each Series A Preferred
 Unit shall be treated as one Partnership Unit.

                  Section  7.  Transfer  Restrictions.  The  holders of Series A
 Preferred  Units shall be subject to all of the provisions of Section 11 of the
 Partnership Agreement.

                  Section 8. No Conversion  Rights.  The holders of the Series A
 Preferred  Units shall not have any rights to convert such units into shares of
 any other class or series of stock or into any other securities of, or interest
 in,  the  Partnership.  Section 9. No Sinking  Fund.  No sinking  fund shall be
 established for the retirement or redemption of Series A Preferred Units.

                  Section 10.  Exhibit A to Partnership  Agreement.  In order to
 duly reflect the issuance of the Series A Preferred  Units provided for herein,
 the Partnership Agreement is hereby further amended pursuant to Section 12.3 of
 the  Partnership  Agreement by  replacing  the current form of Exhibit A to the
 Partnership  Agreement  with the form of  Exhibit  A that is  attached  to this
 amendment as Exhibit C.

                  Section 11. Inconsistent  Provisions.  Nothing to the contrary
 contained  in the  Partnership  Agreement  shall  limit  any of the  rights  or
 obligations set forth in this Amendment.

                  IN WITNESS WHEREOF, this Amendment has been executed as of the
 date first above written.
