             1.7 Other Activities.

                 (a) The Limited Partners acknowledge that the PSA Affiliates
are engaged in the business, directly and indirectly, of acquiring, owning,
developing, leasing, managing and operating self-storage facilities. The Limited
Partners understand that the PSA Affiliates may be involved, directly or
indirectly, in various other projects and businesses not included in the
Partnership. The Partners hereby agree that the creation of the Partnership and
involvement herein by each of the Partners shall not prejudice their rights (or
the rights of their Affiliates) to have such other interests and activities and
to enjoy profits or other benefits therefrom, and each Partner waives any rights
it might otherwise have to share or participate in such other interests or
activities of the other Partners or their Affiliates. Except as otherwise
provided in this Agreement, the Partners and their Affiliates may engage in or
possess any interest in any other business venture of any nature or description,
independently or with others, including without limitation, the acquisition,
ownership, development, leasing, managing and operation of self-storage
facilities or other real property and the acquisition and ownership of stock or
securities, and neither the Partnership nor any Partner shall have any right by
virtue of this Agreement in and to such venture or the income or profits derived
therefrom.

                 (b) Notwithstanding the provisions of Section 1.7(a) above,
PSA, by its signature to this Agreement, has granted the Partnership the first
right and opportunity to develop and own Qualifying Projects as set forth below
and as listed on Exhibits A-1, A-2, and A-3 in accordance with this Agreement,
and PSA and the General Partner agree to ensure that no PSA Affiliates shall
develop a Qualifying Project without complying with the provisions of this
Section, Section 6.2 and Section 6.4.

                 The Partnership has been formed, and the General Partner shall
use its best efforts to cause the Partnership, to undertake the development
initially of a group of Projects through and including the development of the
Project that causes cumulative Project Budgeted Costs to exceed $100,000,000.
The first Projects of the Partnership are identified on Exhibits A-1 and A-2,
which also indicate the estimated Project Budgeted Costs of those Projects.
Exhibit A-3 identifies the pool of Qualifying Projects from which the balance of
the initial group of Projects of the Partnership is expected to be selected.
Exhibit A-3 also sets forth the estimated Project Budgeted Costs of those
Projects.

                 The General Partner shall cause PSA, from time to time, to
amend the list of Qualifying Projects on Exhibits A-2 or A-3 to reflect: (A) the
deletion of Qualifying Projects that no longer are expected to be acquired by
the Partnership because (i) the Investment Committee has rejected such
Qualifying Projects under Section 6.2, (ii) such Qualifying Projects do not meet
the standards for Qualifying Projects or for development by the Partnership in
accordance with this Agreement, (iii) none of the Partnership, PSA or any of
their respective Affiliates is pursuing development of such Qualifying Projects
any longer (including circumstances in which conditions to the acquisition of
those Qualifying Projects are unable to be satisfied); or (iv) the Partnership
has already undertaken development of sufficient Projects so that the deleted
Qualifying Project or Projects are no longer needed to satisfy the 150% standard
described in the following sentence (Qualifying Projects proposed to be deleted
pursuant to this clause (iv) shall be submitted to the Investment Committee and
shall be deleted unless the Investment Committee within thirty (30) days
determines not to permit the deletion of that specific Qualifying Project and
the Investment Committee instead substitutes for deletion another Qualifying
Project or Projects then listed on the relevant exhibit calling for an equal or
greater amount of Project Budgeted Costs, or if not then finalized in accordance
with Section 6.2, the estimated amounts thereof provided to the Investment
Committee), and (B) the addition of further Qualifying Projects; provided that
the net effect of any such deletions or additions (assuming the specified
properties were to be acquired by the Partnership) shall not reduce the Yield
expected to be realized by the Partnership from its Projects below eleven and
one half percent (11.5%). The General Partner shall use its best efforts to
ensure that the aggregate Project Budgeted Costs of the pool of Qualifying
Projects identified on Exhibit A-3 at any time will be no less than 150% of the
Partnership's uncommitted initial development capital (i.e., 150% of the excess
of $100,000,000 over the aggregate Project Budgeted Costs of all Projects
undertaken by the Partnership to that date). During any period that the
aggregate Project Budgeted Costs of the pool of Qualifying Projects listed on
Exhibit A-3 do not meet that standard, the General Partner shall cause PSA to
afford the Partnership the first right and opportunity to develop and own any
Qualifying Project that is proposed to be developed by any PSA Affiliate (not
just those properties identified on Exhibit A-3) that has not at that time been
committed to development in a transaction involving other parties.

                 The Partnership's first right and opportunity to develop
Qualifying Projects described in this Section 1.7(b) shall expire on the earlier
of (i) the third anniversary of the Effective Date, provided that the General
Partner and PSA are then in compliance with the provisions of this Section
1.7(b) or (ii) the date the Partnership has completed the acquisition of
Projects requiring Project Budgeted Costs in excess of $100,000,000.

     directors declaring such a dividend or in accordance with the

     the PSA Equity Shares);

provided, however, that in the case of (iv) or (v) the action taken would
prejudice the Investor Limited Partner in a materially adverse manner and such

asset's adjusted basis for federal income tax purposes, except as follows:

                     (i) The initial Gross Asset Value of any asset contributed
     by a Partner to the Partnership shall be the gross fair market value of
     such asset, as determined by the Partners (as described below the Partners
     have agreed that the gross fair market value of Projects contributed by the
     General Partner and the PS Limited Partner to the Partnership at the time
     of contribution will be based on the cost of those Projects as set forth in

                     (ii) The Gross Asset Values of all Partnership assets shall
     be adjusted to equal their respective gross fair market values, as

     necessary or appropriate to reflect the relative economic interests of the
     Partners in the Partnership;

                     (iii) The Gross Asset Value of any Partnership asset
     distributed to any Partner shall be the gross fair market value of such
     asset on the date of distribution; and

                     (iv) The Gross Asset Values of Partnership assets shall be
     increased (or decreased) to reflect any adjustments to the adjusted basis
     of such assets pursuant to Code Section 734(b) or Code Section 743(b), but
     only to the extent that such adjustments are taken into account in
     determining Capital Accounts pursuant to Regulation Section
     1.704-1(b)(2)(iv)(m) and Sections 1.8(xx) and 3.5(g); provided, however,
     that Gross Asset Values shall not be adjusted pursuant to this Section
     1.8(aa)(iv) to the extent the Partners determine that an adjustment
     pursuant to Section 1.8(aa)(ii) is necessary or appropriate in connection
     with a transaction that would otherwise result in an adjustment pursuant to
     this Section 1.8(aa)(iv).

If the Gross Asset Value of an asset has been determined or adjusted pursuant to
Section 1.8(aa)(i), 1.8(aa)(ii) or 1.8(aa)(iv), such Gross Asset Value shall

     to be taken into account in determining Capital Accounts as a result of a
     distribution other than in liquidation of a Partner's interest in the
     Partnership, the amount of such adjustment shall be treated as an item of
     gain (if the adjustment increases the basis of the asset) or loss (if the
     adjustment decreases the basis of the asset) from the disposition of the
     asset and shall be taken into account for purposes of computing Profits or

Shortfall shall be the amount that, when added to the distribution of the Net
Equity, would increase the calculated Realized Rate of Return by one twelfth of

                     (iii) The General Partner and PS Limited Partner also shall

cumulative Project Budgeted Costs to exceed $100,000,000.

                 (g) Cost Overrun Contributions. To the extent that the

written notices from the General Partner to the Partners in the form attached as
Exhibit K hereto. Such notices shall contain a breakdown and supporting evidence
of Land Acquisition Costs and Basic Development Costs, and a breakdown by

supporting evidence as requested by the Investor Limited Partner) and balance of
cost to complete, together with any replenishment of Development Working
Capital. Such notices shall be given on or about the 25th day of each month and
shall estimate the Capital Contributions required for that month based on the
Project Budgeted Costs. Such Capital Contributions shall be paid within ten
Business Days of delivery of the applicable notice from the General Partner.

                 (j) Final Costs; Limit on Investor Limited Partner's
Contributions. Notwithstanding anything herein to the contrary, the Investor
Limited Partner's obligation to make Capital Contributions shall be limited to
the lesser of (i) $98,000,000 or (ii) $49,000,000 plus 49% of Project Budgeted
Costs on a cumulative basis. Unused Development Working Capital reserves shall
be applied to pay the final Project Budgeted Costs of the Partnership, which
would otherwise be provided for by Capital Contributions, but only with respect
to the Project Budgeted Costs of the initial group of Projects undertaken by the
Partnership through and including the Project that causes the Partnership's
cumulative Project Budgeted Costs to exceed $100,000,000.

Capital Contributions shall be distributed by the Partnership to the General
Partner and the PS Limited Partner (in a 1/50 ratio) as a reduction in their
Capital Contributions. The Partners acknowledge that these amounts will be
treated as contributed to the Partnership and then distributed by the
Partnership for purposes of this Agreement, notwithstanding that for federal
income tax purposes the amounts perhaps could be recharacterized as if paid by
the Investor Limited Partner to the General Partner and PS Limited Partner for
an interest in the Projects which the Investor Limited Partner then would be
treated as contributing to the Partnership. Such a recharacterization, in the
Partnership's circumstances, is not expected to produce materially differing
consequences.

             2.3 Purchase of PSA Equity Shares. Concurrently with the execution
of this Agreement, the Partnership and PSA have executed the Stock Purchase
Agreement attached hereto as Exhibit N. On the Initial Funding Date, PSA shall
issue to the Partnership $100,000,000 of PSA Equity Shares pursuant to the Stock
Purchase Agreement. The parties agree that the agreed fair market value of the
PSA Equity Shares at the time of purchase is $100,000,000.

contracts or any other obligations of the Partnership; and

                 (b) A Partner shall be liable only to make the future Capital
Contributions provided in Section 2.2 for Qualifying Projects approved under
Section 6.2(b) and shall not be required to lend any funds to the Partnership.

Performance of any one or more of the acts specifically authorized for
performance by any Limited Partner under this Agreement shall not in any way
constitute the Limited Partner a general partner or impose any personal
liability on the Limited Partner. The General Partner shall have no personal
liability for the repayment of any Capital Contributions of the Limited
Partners.

             2.5 Other Matters.

                 (a) Except as otherwise provided in this Agreement, no Partner
shall demand or receive a return of its Capital Contributions or withdraw as a
Partner from the Partnership without the consent of the Partners. Under
circumstances requiring a return of any Capital Contributions, no Partner shall
have the right to receive property other than cash except as may be specifically
provided herein.

                 (b) No Partner shall receive any interest, salary or draw with
respect to its Capital Contributions or its Capital Account or for services
rendered on behalf of the Partnership or otherwise in its capacity as a Partner,
except as otherwise provided in this Agreement.

         3.  Allocations

             3.1 Profits. After giving effect to the special allocations set
forth in Sections 3.3, 3.4 and 3.5, Profits for any Fiscal Year or other period
shall be allocated to the Partners in the following order and priority:

                 (a) First,

                     (i) if and to the extent that Losses have been allocated to
     the General Partner and PS Limited Partner pursuant to Section 3.2(c),
     Profits initially shall be allocated to the General Partner and PS Limited
     Partner, and

                     (ii) if and to the extent that Losses have been allocated
     to the Partners pursuant to Section 3.2(a) or (b), Profits shall be
     allocated to the Partners in the reverse order of the allocation of those
     Losses.

                 (b) Then,

                     (i) until November 17, 2005, (A) initially to the Investor
     Limited Partner until the Investor Limited Partner has been allocated
     cumulative Profits pursuant to this Section 3.1(b)(i)(A) equal to the
     aggregate accrued Priority Allocation of the Investor Limited Partner, and
     (B) then to the General Partner and PS Limited Partner (in a 1/50 ratio)
     until the General Partner and PS Limited Partner have been allocated
     cumulative Profits pursuant to this Section 3.1(b)(i)(B) equal to the
     aggregate accrued Priority Allocation of the General Partner and PS Limited
     Partner; and

                     (ii) after November 17, 2005, (A) initially to the Investor
     Limited Partner until the Investor Limited Partner has been allocated
     cumulative Profits pursuant to Section 3.1(b)(i)(A) and this Section
     3.1(b)(ii)(A) equal to the aggregate Priority Distribution of the Investor
     Limited Partner, whether or not distributed, and (B) then to the General
     Partner and PS Limited Partner until the General Partner and PS Limited
     Partner have been allocated (in a 1/50 ratio) cumulative Profits pursuant
     to Section 3.1(b)(i)(B) and this Section 3.1(b)(ii)(B) equal to the
     aggregate Priority Distribution of the General Partner and PS Limited
     Partner, whether or not distributed.

                 (c) Finally, the remaining balance, if any, shall be allocated
to the Partners in proportion to their Percentage Interests.

             3.2 Losses. After giving effect to the special allocations set
forth in Sections 3.3, 3.4 and 3.5:

                 (a) Losses (other than Losses from the sale or other
disposition of the Partnership's assets) for any Fiscal Year or other period
shall be allocated to the Partners in proportion to their Percentage Interests.

                 (b) Losses from the sale or other disposition of the
Partnership's assets for any Fiscal Year or other period shall be allocated to
the Partners in proportion to the then positive balances of their capital
accounts.

                 (c) If and to the extent that an allocation of Losses to the
Investor Limited Partner pursuant to the preceding Sections 3.2(a) or (b) would
result in the Investor Limited Partner having an Adjusted Capital Account
Deficit, any such excess Losses instead shall be allocated to the General
Partner and PS Limited Partner (in a 1/50 ratio).

             3.3 Special Allocations to the General Partner. The following
special allocations shall be made:

                 (a) Items of gross loss or expense shall be allocated to the
General Partner and the PS Limited Partner in proportion to their Capital
Contributions pursuant to Section 2.2(g) (Cost Overrun Contributions) until the
cumulative allocations pursuant to this Section 3.3(a) equal the aggregate
amount of their Capital Contributions pursuant to Section 2.2(g).

                 (b) All Depreciation shall be specially allocated to the
General Partner and PS Limited Partner (in a 1/50 ratio).

                 (c) All deductions for any guaranteed payments made to the
Investor Limited Partner pursuant to Section 2.2(h) (Shortfall Contributions)
shall be specially allocated to the General Partner.

             3.4 Gain from Sale. All Gain from Sale shall be allocated in the
following order:

                 (a) First, to cause the Capital Accounts of the General
Partner, the PS Limited Partner and the Investor Limited Partner to be in
proportion to their respective Percentage Interests.

                 (b) Finally, the remaining balance, if any, shall be allocated
to the Partners in proportion to their Percentage Interests.

             3.5 Regulatory Special Allocations. The following special
allocations shall be made in the following order:

                 (a) Minimum Gain Chargeback. Except as provided in Section
1.704-2(f) of the Regulations, notwithstanding any other provision of this
Article 3, if there is a net decrease in Minimum Gain during any Fiscal Year,
each Partner shall be specially allocated items of Partnership income and gain
for such year (and, if necessary, subsequent years) in an amount equal to the
portion of such Partner's share of the net decrease in Minimum Gain, determined
in accordance with Regulations Section 1.704-2(g). Allocations pursuant to the
previous sentence shall be made in proportion to the respective amounts required
to be allocated to each Partner pursuant thereto. The items to be so allocated
shall be determined in accordance with Sections 1.704-2(f)(6) and 1.704-2(j)(2)
of the Regulations. This Section 3.5(a) is intended to comply with the minimum
gain chargeback requirement in Section 1.704-2(f) of the Regulations and shall
be interpreted consistently therewith.

                 (b) Partner Nonrecourse Debt Minimum Gain Chargeback. Except as
otherwise provided in Section 1.704-2(i)(4) of the Regulations, notwithstanding
any other provision of this Article 3 except Section 3.5(a), if there is a net
decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner
Nonrecourse Debt during any Fiscal Year, each Partner who has a share of the
Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse
Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be
specially allocated items of Partnership income and gain for such year (and, if
necessary, subsequent years) in an amount equal to such Partner's share of the
net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such
Partner Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in
proportion to the respective amounts required to be allocated to each Partner
pursuant thereto. The items to be so allocated shall be determined in accordance
with Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the Regulations. This Section
3.5(b) is intended to comply with the minimum gain chargeback requirement in
Section 1.704-2(i)(4) of the Regulations and shall be interpreted consistently
therewith.

                 (c) Qualified Income Offset. In the event any Partner
unexpectedly receives any adjustments, allocations or distributions described in
Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) of the Regulations, items of
Partnership income and gain shall be specially allocated to each such Partner in
an amount and manner sufficient to eliminate, to the extent required by the
Regulations, the Adjusted Capital Account Deficit of such Partner as quickly as
possible, provided that an allocation pursuant to this Section 3.5(c) shall be
made only if and to the extent that such Partner would have an Adjusted Capital
Account Deficit after all other allocations provided for in this Article 3 have
been tentatively made as if this Section 3.5(c) were not in this Agreement.

                 (d) Gross Income Allocation. In the event any Partner has a
deficit Capital Account at the end of any Partnership Fiscal Year which is in
excess of the sum of (i) the amount such Partner is obligated to restore
pursuant to any provision of this Agreement, and (ii) the amount such Partner is
deemed to be obligated to restore pursuant to the penultimate sentences of
Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be
specially allocated items of Partnership income and gain in the amount of such
excess as quickly as possible, provided that an allocation pursuant to this
Section 3.5(d) shall be made if and only to the extent that such Partner would
have a deficit Capital Account in excess of such sum after all other allocations
provided for in this Article 3 have been tentatively made as if Section 3.5(c)
and this Section 3.5(d) were not in the Agreement.

                 (e) Nonrecourse Deductions. Nonrecourse Deductions for any
Fiscal Year or other period shall be specially allocated to the General Partner.

                 (f) Partner Nonrecourse Deductions. Any Partner Nonrecourse
Deductions for any Fiscal Year or other period shall be specially allocated to
the Partner who bears the economic risk of loss with respect to the Partner
Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable
in accordance with Regulations Section 1.704-2(i)(1).

                 (g) Section 754 Adjustment. To the extent an adjustment to the
adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) or
Code Section 743(b) is required, pursuant to Regulations Section
1.704-1(b)(2)(iv)(m)(2) or Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be
taken into account in determining Capital Accounts as the result of a
distribution to a Partner in complete liquidation of its interest in the
Partnership, the amount of such adjustment to the Capital Accounts shall be
treated as an item of gain (if the adjustment increases the basis of the asset)
or loss (if the adjustment decreases such basis) and such gain or loss shall be
specially allocated to the Partners in accordance with their interests in the
Partnership in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(2)
applies, or to the Partners to whom such distribution was made in the event that
Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

                 (h) Curative Allocations. The allocations set forth in Sections
3.5(a) through (g) (the "Regulatory Allocations") are intended to comply with
certain requirements of the Regulations. It is the intent of the Partners that,
to the extent possible, all Regulatory Allocations shall be offset either with
other Regulatory Allocations or with special allocations of other items of
Partnership income, gain, loss or deduction pursuant to this Section 3.5(h).
Therefore, notwithstanding any other provision of this Article 3 (other than the
Regulatory Allocations), the General Partner shall make such offsetting special
allocations of Partnership income, gain, loss or deduction in whatever manner
the General Partner determines is appropriate so that, after such offsetting
allocations are made, each Partner's Capital Account balance is, to the extent
possible, equal to the Capital Account balance such Partner would have had if
the Regulatory Allocations were not part of the Agreement. In exercising its
discretion under this Section 3.5(h), the General Partner shall take into
account future Regulatory Allocations under Sections 3.5(a) and 3.5(b) that,
although not yet made, are likely to offset other Regulatory Allocations
previously made under Sections 3.5(e) and 3.5(f).

             3.6 Other Allocations Rules.

                 (a) Except as otherwise provided, all Profits and Losses
allocated to the Partners shall be allocated among them in proportion to their
Percentage Interests.

                 (b) For purposes of determining the Profits, Losses or any
other items allocable to any period, Profits, Losses and any such other items
shall be determined on a daily, monthly, or other basis, as determined by the
General Partner using any permissible method under Code Section 706 and the
Regulations thereunder.

                 (c) Except as otherwise provided in this Agreement, all items
of Partnership income, gain, loss, deduction, credit and any other allocations
not otherwise provided for shall be divided among the Partners in the same
proportions as they share Profits or Losses, as the case may be, for the year.

                 (d) To the extent permitted by Section 1.704-2(h)(3) of the
Regulations, the General Partner shall endeavor to treat distributions of
Operating Cash as having been made from the proceeds of a Nonrecourse Liability
or a Partner Nonrecourse Debt only to the extent that such distributions would
cause or increase an Adjusted Capital Account Deficit for any Partner.

             3.7 Tax Allocations: Code Section 704(c). In accordance with Code
Section 704(c) and the Regulations thereunder, income, gain, loss and deduction
with respect to any property contributed to the capital of the Partnership
shall, solely for tax purposes, be allocated among the Partners so as to take
account of any variation between the adjusted basis of such property to the
Partnership for federal income tax purposes and its initial Gross Asset Value
(computed in accordance with Section 1.8(aa)(i)).

                  In the event the Gross Asset Value of any Partnership asset is
adjusted pursuant to Section 1.8(aa)(ii), subsequent allocations of income,
gain, loss and deduction with respect to such asset shall take account of any
variation between the adjusted basis of such asset for federal income tax
purposes and its Gross Asset Value in the same manner as under Code Section
704(c) and the Regulations thereunder.

                  Any elections or other decisions relating to such allocations
shall be made by the General Partner in any manner that reasonably reflects the
purpose and intention of this Agreement. Allocations pursuant to this Section
3.7 are solely for purposes of federal, state and local taxes and shall not
affect, or in any way be taken into account in computing, any Partner's Capital
Account or share of Profits, Losses other items or distributions pursuant to any
provision of this Agreement.

         4.  Operating Cash and Capital Proceeds

             4.1 Operating Cash. Except as otherwise provided in Section 10,
Operating Cash, if any, shall be distributed or invested as provided in this
Section 4.1. To the extent distributed, Operating Cash shall be distributed to
the Partners monthly, on the 15th day of each month or the next Business Day if
the 15th day is not a Business Day, for the preceding month, or at such other
times as the Partners may determine as follows:

                 (a) Until November 17, 2005, Operating Cash, if any, shall be
first distributed to the Investor Limited Partner in an amount equal to any
unpaid Priority Distribution of the Investor Limited Partner, and any balance of
the Operating Cash shall in the discretion of the General Partner either be (1)
added to the Partnership's working capital, (2) used to purchase PSA Common
Shares in the open market or (3) with the approval of the Investment Committee,
used to develop additional Qualifying Projects, provided that the General
Partner shall use its reasonable efforts to ensure that any such Operating Cash
accumulated in excess of reasonable working capital reserves (for the purposes,
and to the extent, otherwise authorized hereunder, other than such PSA Common
Share purchases and the development of Qualifying Projects) and funds committed
for development of Qualifying Projects approved by the Investment Committee or
for the purchase of PSA Common Shares shall not exceed $10,000,000 at any time;

                 (b) Subject to the provisions of Section 9.1, after November
17, 2005, Operating Cash, if any, shall be distributed in the following order of
priority:

                     (i) First, to the Investor Limited Partner until the
     Investor Limited Partner has received the amount of any unpaid Priority
     Distribution of the Investor Limited Partner;

                     (ii) Second, to the General Partner and PS Limited Partner
     until the General Partner and PS Limited Partner have received the amount
     of any unpaid Priority Distribution of the General Partner and PS Limited
     Partner;

                     (iii) Third, to the Partners in proportion to their
     Percentage Interests; provided however, that between November 17, 2005 and
     November 17, 2011, any such distribution shall only be made with the
     approval of the Investment Committee, and if the Investment Committee does
     not approve the distribution of any such excess Operating Cash, such
     Operating Cash shall, in the discretion of the General Partner, either be
     (1) added to the Partnership's working capital or (2) used to purchase PSA
     Common Shares in the open market, provided that the General Partner shall
     use its reasonable efforts to ensure that any such Operating Cash
     accumulated in excess of reasonable working capital reserves (for the
     purposes, and to the extent, otherwise authorized hereunder, other than
     such PSA Common Share purchases and the development of Qualifying Projects)
     and funds committed for development of Qualifying Projects approved by the
     Investment Committee or for the purchase of PSA Common Shares shall not
     exceed $10,000,000 at any time.

             4.2 Capital Proceeds. Except as otherwise specified in this
Agreement, Capital Proceeds, if any, shall be distributed to the Partners on the
third Business Day after a sale or financing or at such other times as the
Partners may determine in the same order and priority as Operating Cash,
provided, however, that if such a distribution of Capital Proceeds in the
fashion described in Section 4.1(b)(iii) would create an Adjusted Capital
Account Deficit for any Partner that is not at the time of distribution
reasonably expected to be eliminated by future Partnership allocations,
distributions of Capital Proceeds at that time shall cease until the earlier of
the time at which (i) they can be so distributed without creating such a deficit
or (ii) a Liquidating Event (as defined in Section 10.1) takes place (and in
that case, any distribution will be made pursuant to Section 10.2).

             4.3 Amounts Withheld. If required by applicable law, the General
Partner shall cause the Partnership to withhold such amounts as may be required
from any payment or distribution from the Partnership to a Partner, and the
General Partner shall remit such amounts on a timely basis to the tax authority
or other entity entitled to them. Any (a) amounts so withheld or (b) estimated
or other payments to tax authorities with respect to any Profits or other items
allocable to the Partners, shall be treated as amounts distributed to the
Partners pursuant to this Section 4 for all purposes. The General Partner shall
allocate any such amounts among the Partners in accordance with applicable law.

         5.  Management

             5.1 Managing Partner. The Partnership shall be managed by the
General Partner. The Limited Partners shall not participate in the management of
the Partnership's business, and shall have no power to bind or act on behalf of
the Partnership.

             5.2 Authority of Managing Partner. The General Partner shall have,
subject to the control of the Partners to the extent (and only the extent)
provided herein, supervision, direction and control of the business of the
Partnership. Subject to the limitations and restrictions set forth in this
Agreement, the General Partner shall act on behalf of the Partnership in all
matters affecting the management and supervision of the Partnership and its
business affairs, and shall have all rights and powers generally conferred by
law or otherwise necessary, advisable or consistent therewith, including the
right to vote the PSA Equity Shares and any PSA Common Shares. Without limiting
the scope of the foregoing, the Partners agree and acknowledge that it is their
intention and desire to confer upon the General Partner, to the fullest extent
permissible under the Act and other provisions of applicable law, and subject
only to the express limitations set forth in Section 5.3, full power and
authority relative to any and all matters relating to or affecting the
Partnership and its affairs.

             Notwithstanding any provision of this Agreement, including without
limitation Section 5.3, any Person dealing with the Partnership may rely
(without duty of further inquiry) upon a certificate signed by the General
Partner as to:

                 (a) The identity of the General Partner or any Partner;

                 (b) The existence or nonexistence of any fact or facts which
constitute a condition precedent to acts by the General Partner or which are in
any other manner germane to the affairs of the Partnership;

                 (c) The Persons who are authorized to execute and deliver any
instrument or document of the Partnership; or

                 (d) Any act or failure to act by the Partnership or any other
matter whatsoever involving the Partnership or any Partner.

             5.3 Limitations on Rights and Powers. Except by the unanimous
consent of the Partners, the General Partner shall not have authority to:

                 (a) Require additional Capital Contributions to be made to the
Partnership in addition to the Capital Contributions required to be made
pursuant to Section 2.2;

                 (b) Enter into or commit to any agreement, contract, commitment
or obligation on behalf of the Partnership obligating the Limited Partners to
contribute additional capital, to make or guarantee a loan or to increase the
Limited Partners' liability either to the Partnership or to third parties;

                 (c) Except as is otherwise provided in this Agreement, receive
or permit any Partner or Affiliate of a Partner to receive any fee or rebate, or
to participate in any reciprocal business arrangements that would have the
effect of circumventing any of the provisions of this Agreement;

                 (d) Materially alter the business of the Partnership as
provided for in this Agreement;

                 (e) Do any act in contravention of this Agreement;

                 (f) Except as is otherwise provided in this Agreement, possess
Property, or assign rights in specific Property, for other than a Partnership
purpose;

                 (g) Cause the Partnership to borrow money or obtain any
financing, pledge or encumber any of the Property, or enter into or commit to
any agreement contract, commitment or obligation on behalf of the Partnership to
take any of those actions; or

                 (h) Except as provided in Article 8, admit any Person as a
Partner.

Except as otherwise contemplated by this Agreement or provided for in the
Initial Business Plans, no action specified on the attached Exhibit B shall be
taken by the General Partner without approval of the Investor Limited Partner.

             5.4 Project Development. All phases of site selection, development
and construction of Projects shall be carried out by employees of PSA Affiliates
and independent contractors engaged by the General Partner for and on behalf of
the Partnership in accordance in all material respects with the specifications
and information approved by the Investment Committee. In order for any
Qualifying Project to be contributed to or acquired by the Partnership, and
before the Investor Limited Partner shall have to make any Capital Contribution
for such a Qualifying Project under Section 2.2(b), the General Partner shall
complete all the items listed on the acquisition checklist attached as Exhibit C
to the satisfaction of the Investment Committee. If land for a Qualifying
Project is required to be acquired prior to the satisfaction of the items listed
on such checklist and the land is acquired by a single member limited liability
company that is treated for income tax purposes as a disregarded entity and has
no assets, liabilities or business other than its ownership of such Qualifying
Project, then upon satisfaction of the items in the checklist, the Partnership
shall accept, in lieu of a deed, a transfer of all ownership interests in that
limited liability company, provided that the General Partner agrees to indemnify
the Investor Limited Partner against any loss or liability to the Partnership
that is attributable to that limited liability company and that would not have
been incurred by the Partnership if the Project had been acquired and held
directly by the Partnership, rather than through the limited liability company.

             For up to 14 of the Projects listed on Exhibits A-1 and A-2, plans
and specifications may be reviewed by a third-party consultant acceptable to the
Investor Limited Partner and the cost of that review, not to exceed $4,000 per
Project, shall be paid for by the Partners (1% by the General Partner, 50% by
the PS Limited Partner and 49% by the Investor Limited Partner), with any excess
over $4,000 per each of those 14 Projects being paid for by the Investor Limited
Partner. For any other Projects, plans and specifications may be reviewed by a
third-party consultant acceptable to the Investor Limited Partner and the cost
of that review, not to exceed $2,000 per Project, shall be paid for by the
Partners (1% by the General Partner, 50% by the PS Limited Partner and 49% by
the Investor Limited Partner), with any excess over $2,000 per Project being
paid for by the Investor Limited Partner. Copies of the final title policy in
the amount of the Project Budgeted Costs, deed into the Partnership and closing
statement for the acquisition shall be furnished to the Investor Limited
Partner's advisor and attorneys within 30 days after payment of the initial
Capital Contribution for a Project. The General Partner and the Investor Limited
Partner shall attempt, to the extent feasible, to develop an approved list of
architects and environmental consultants for the Projects. PSA Affiliates shall
be responsible for arranging, supervising and coordinating all activities,
purchases and services associated with the development of each Qualifying
Project which is or is to become a Project including, without limitation, the
following:

                 (a) Review and analysis of the suitability for the Partnership
of each Qualifying Project;

                 (b) Negotiation and documentation of the terms of each
acquisition of property for development;

                 (c) Conduct of such "due diligence" and obtaining of such
studies, reports and approvals as are required in connection with the
prospective acquisition of each property, including a review and studies,
reports and approvals, as required, as to soils, environmental issues, title and
survey matters, zoning and other land use issues and economic feasibility;

                 (d) Obtaining of necessary building permits and other approvals
required for development;

                 (e) Negotiation and closing of the acquisition of each
Qualifying Project;

                 (f) Coordination with planners and engineers on matters
relating to the design of each Qualifying Project and any modifications thereof;

                 (g) Coordination with contractors regarding costs and
performance of construction and other development activity;

                 (h) Negotiation and preparation for execution by the
Partnership, or for the account of the Partnership, by PSA Affiliates of
construction contracts and other contracts for the supply of services and/or
material necessary to perform and complete the development of each Project;

                 (i) Negotiation, preparation and execution of all change orders
(provided that all material changes to materials or methods of construction
shall be approved in advance by the Investor Limited Partner or the Investment
Committee);

                 (j) Review and approval of applications for payment submitted
by contractors in connection with the development of each Project and
maintenance of accurate and complete books of account and other records relating
thereto;

                 (k) Negotiation with suppliers of major building components, if
any, where such items are not covered by a general construction contract, and
purchase of such components;

                 (l) Performance of normal business functions of an owner of
property in administering all aspects of the development of each Project
(including property acquisition);

                 (m) If necessary, and not performed under a general contract,

authorities for, and obtaining of, agreements relating to utility and sewer
easements and the provision of adequate utility and sewer service to each
Project; and

                 (n) The engagement of such independent contractors and
professional firms including, but not limited to, construction firms,
architects, environmental consultants, engineers, architects and attorneys, as
may be required or appropriate in connection with the foregoing, it being
understood and agreed that virtually all of the activity described above in this
Section 5.4 will be undertaken by independent contractors and firms whose
charges will be borne by PSA Affiliates or by the Partnership as herein
provided.

             5.5 Compensation and Reimbursement. Subject to the limitations
provided herein, and except as otherwise provided in this Agreement or agreed to
by the Partners, PSA Affiliates shall be entitled to receive the following, and
only the following, compensation and reimbursement from the Partnership:

                 (a) The Partnership shall enter into the Management Agreement
in the form attached as Exhibit D (provided that in the event of any conflict
between the Management Agreement and this Agreement, this Agreement shall
prevail, and the Management Agreement shall so specify) relative to the
operation and management of each Project, pursuant to which PSA Affiliates shall
be entitled to receive a management fee equal to 6% of gross operating revenues
from each Project (not including revenue earned pursuant to the Master Lease
Agreement referred to in Section 5.5(e) below or any revenue earned by PSA with
respect to truck rental operations undertaken at the Projects);

                 (b) In connection with the development of each Project, PSA
Affiliates shall be entitled to reimbursement for Land Acquisition Costs, Basic
Development Costs and PSA Affiliates Operating Costs as and to the extent
provided in Section 2.2;

                 (c) PSA Affiliates shall be entitled to reimbursement, on
submission of an itemized account, of all reasonable sums paid to unaffiliated
Persons for goods and materials for the direct benefit of the Partnership;

                 (d) PSA Affiliates shall be entitled to reimbursement for the
direct personnel cost (without overhead) for tax preparation and other services
provided as necessary for the conduct of the Partnership's affairs, including
preparation of reports to the Investor Limited Partner, as distinguished from
acquisition, development, operation and management of the Projects, provided
such cost does not exceed the amount the Partnership would be required to pay
other Persons not affiliated with the General Partner for comparable services;
and

                 (e) The Partnership shall enter into the Master Lease Agreement
in the form attached as Exhibit E relative to the lease of space to the General
Partner or its Affiliate in the Projects for retail storage related uses
involving the general public and self-storage tenants.

Except as expressly provided for in this Section 5.5 or otherwise approved by
the Partners, no payment shall be made by the Partnership to a PSA Affiliate for
services of such PSA Affiliate or any officer or employee thereof, and no
payments shall be made to PSA Affiliates that would have the effect of providing
PSA Affiliates with double compensation for services or capital or double
reimbursement for expenses incurred.

             5.6 Hazardous Materials.

                 (a) The General Partner shall use its reasonable best efforts
to keep and maintain the Property in compliance with, and not to cause, and
shall use its reasonable efforts not to permit, the Property to be in violation
of, any Hazardous Materials Laws. The General Partner shall not dispose of any
waste (including, without limitation, any Hazardous Materials) on, under or
about the Projects and shall not use, generate, manufacture, or store any
Hazardous Materials on, under or about the Projects or transport to or from the
Projects (and shall use its reasonable efforts not to permit anyone else to do
any of the foregoing) in violation of any Hazardous Material Laws. The General
Partner shall not install or permit the installation of any underground storage
tanks on the Projects.

                 (b) The General Partner shall immediately advise the Partners
in writing of (i) any and all enforcement, cleanup, removal, or other
governmental or regulatory actions instituted, completed or threatened pursuant
to any Hazardous Materials Laws of which actions the General Partner has actual
knowledge; (ii) all claims made or threatened by any third party against the
Partnership or any Partner or the Projects relating to damage, loss or injury
resulting from, or contribution, cost recovery or compensation for, any
Hazardous Materials, of which claims the General Partner has actual knowledge
(the matters set forth in clauses (i) and (ii) above are collectively referred
to in this Agreement as "Hazardous Materials Claims"); and (iii) the General
Partner's actual knowledge of any occurrence or condition on the Projects or on
any real property adjoining or in the vicinity of the Projects that the General
Partner knows could cause the Projects or any part thereof to be subject to any
restrictions on the ownership, occupancy, transferability or use of the Projects
under any Hazardous Materials Laws.

                 (c) Without the prior written approval of the Investor Limited
Partner, the General Partner shall not take any remedial action in response to
the presence of any Hazardous Materials on, under or about the Projects, nor
enter into any settlement agreement, consent decree other compromise in respect
to any Hazardous Materials Claims; provided, however, that the prior approval of
all Partners shall not be necessary in the event that the presence of Hazardous
Materials on, under or about the Projects, in the reasonable belief of the
General Partner, either poses an immediate threat to the health, safety or
welfare of any individual or is of such a nature that an immediate remedial
response is necessary and it is not possible to obtain such Partners' approval
before taking such action, provided that in such event the General Partner shall
notify all Partners as soon as practicable of any action so taken. All Partners
agree not to withhold their approval, where approval is required under this
Agreement, if either (i) a particular remedial action is ordered by a court of
competent jurisdiction, or (ii) the General Partner establishes to the
satisfaction of the Partners that there is no reasonable alternative to such
remedial action which would result in less impairment of the value of the
Projects.

         6.  Action by Partners; Investment Committee

             6.1 Action by Partners. No annual or regular meetings of the
Partners are required to be held. However, meetings of the Partners may be held
if called by the General Partner or any Partner upon at least four Business
Days' prior written notice. Any consents required of any Partner hereunder shall
be in writing and shall be filed by the General Partner with the books and
records of the Partnership.

             6.2 Investment Committee.

                 (a) The Partnership shall have an investment committee (the
"Investment Committee") which shall consist of four members, two of whom shall
be appointed by the Investor Limited Partner as its representatives and two of
whom shall be appointed jointly by the General Partner and the PS Limited
Partner as their representatives. Initially, the Investor Limited Partner
appoints [Investor Representative 1] and [Investor Representative 2], and the
General Partner and PS Limited Partner appoint Carl B. Phelps and Harvey Lenkin,
as the members of the Investment Committee. In the event of the death or
resignation of any member of the Investment Committee or the removal of any
member of the Investment Committee by the Partner who appointed the same, the
Partner or Partners originally appointing such member of the Investment
Committee shall have the right to appoint his or her successor as its
representative.

                 Meetings of the members of the Investment Committee shall be
held by conference telephone or at the principal executive office of the
Partnership or another appropriate and convenient location designated by the
Investment Committee. Meetings may be called at any time by the General Partner
or by any member of the Investment Committee upon at least seven Business Days'
prior written notice. Any action requiring approval or consent of the Investment
Committee will be deemed to mean approval or consent by at least three of the
Investment Committee members at a meeting of the Investment Committee or,
alternatively, by a writing executed by at least three of the Investment
Committee members.

                 (b) As is described in Section 1.7, PSA has granted the
Partnership certain first rights and opportunities to develop and own proposed
Qualifying Projects.

                     (i) The General Partner shall provide to the members of the
     Investment Committee a detailed description of the Qualifying Projects
     proposed to be developed by the Partnership, including any costs for which
     the General Partner's Capital Account is to be credited under Section
     2.2(d)(i), preliminary financial projections and development costs in the
     form attached as Exhibit F-1 and such other pertinent information,
     including site and building plans, as the Investment Committee shall
     reasonably request. Upon receipt thereof, the Investment Committee shall
     have the option, to be exercised within 30 days, to give approval for the
     Qualifying Project to be undertaken by the Partnership as a Project. The
     Qualifying Projects described on Exhibit A-2 hereto shall be deemed to have
     been approved by the Investment Committee, subject to Section 6.2(b)(iii).

                     (ii) In the event the Investment Committee shall not timely
     elect to, or elects not to, have the Qualifying Project included as a
     Project subject to the terms of this Agreement, PSA Affiliates shall be
     free to develop such Qualifying Project outside of the Partnership, in
     which event the Partnership and the Investor Limited Partner shall have no
     further rights or interests therein. In the event there shall be a 10% or
     greater change in the aggregate costs or in the net rentable square footage
     of such Qualifying Project (as compared to the information submitted under
     Section 6.2(b)(i)), then the Qualifying Project shall be resubmitted to the
     Investment Committee pursuant to this Section 6.2(b) and the Investment
     Committee shall thereafter have the option with respect to such Project
     provided in Section 6.2(b)(i).

                     (iii) If a Qualifying Project is approved based on the
     information submitted under Section 6.2(b)(i), the General Partner shall
     thereafter provide to the members of the Investment Committee finalized
     estimates of development costs and costs of funding any deficiency in Net
     Operating Income until the Project experiences three consecutive calendar
     months of positive monthly Net Operating Income (such final estimates for a
     Project being referred to as "Project Budgeted Costs"), stabilized
     yield-on-cost projections in the form attached as Exhibit F-2 and to the
     extent that there have been any material changes in the site and building
     plans previously submitted, revisions to such plans incorporating such
     changes. In the event those finalized estimates reflect a 10% or greater
     change in the Project Budgeted Costs or net rentable square footage, or a
     reduction of over 25 basis points in Yield, of any Project as compared to
     the information submitted under Section 6.2(b)(i) (or a 10% or greater
     change in the Project Budgeted Costs or reduction of over 12 1/2 basis
     points in Yield for those Projects described on Exhibit A-2), or in the
     event of a material change in the site or building plans, then such change
     must be approved by the Investment Committee for such Qualifying Project to
     be included as one of the Projects subject to the terms of this Agreement.

                 (c) The Partnership's first right to develop Projects under
Sections 1.7(b) and 6.2(b) shall terminate if the General Partner shall have
presented eight consecutive Qualifying Projects to the Investment Committee that
each have a Yield of eleven and one half percent (11.5%) per year or more, and
the Investment Committee shall not have elected to cause any of such Qualifying
Projects to be included as a Project pursuant to this Agreement.

                 (d) The General Partner shall prepare and submit a Business
Plan to the Investment Committee on or before November 15 of each Fiscal Year
that shall apply to the twelve-month period beginning on January 1 of the
subsequent Fiscal Year. The Annual Business Plan shall include an estimated
budget for each Completed Project (as of November 15) for the subsequent Fiscal
Year and a report aggregating all such information for all Completed Projects.

                 (e) The General Partner shall provide to the Investment
Committee any report that any member might reasonably request, if available or
obtainable without significant cost or undue effort, including, but not limited
to, analyses of the Properties and the market, market rent surveys, tenant
traffic reports, tenant turnover statistics, tenant demographic profiles,
projected market values, projected income and expense statements, projected cost
breakdowns and cash flow analyses, summaries of the overall plan of operations
and contemplated transactions, insurance coverages and the like applicable to
the Properties.

             6.3 Opportunity to Invest in Next Development Program. In the event
that any PSA Affiliate seeks to develop another program for investors to
participate in the development and ownership of self-storage facilities prior to
the expiration of the first 12 months after the expiration of the Partnership's
first right and opportunity to develop Qualifying Projects under Section 1.7,
the General Partner shall cause such PSA Affiliate to provide the Investor
Limited Partner with information concerning the first such subsequent proposed
program and to first negotiate in good faith with the Investor Limited Partner
(or a member thereof electing to pursue the same on its own in accordance with
the agreement of the Investor Limited Partner's members) concerning the Investor
Limited Partner's (or such member's) participation in that program before
approaching other investors. Investor Limited Partner acknowledges that its
rights pursuant to this provision are subject to the prior rights, if any,
granted to the limited partner pursuant to the partnership agreement of PSAF
Development Partners, L.P.

             6.4 Development of Competitive Properties. Until such time as at
least 85% of the rentable square footage of any specific Project undertaken by
the Partnership has been leased to third parties in the ordinary course of
business, or November 17, 2005, whichever occurs first, the General Partner
shall ensure that PSA Affiliates will not, in the "micro-market" of that
specific Project (i.e., an area within a radius that, depending upon the density
of the population of consumers potentially using such self storage facilities
and other factors in the particular market ordinarily taken into account in the
exercise of commercially reasonable judgment, extends a minimum of one half
mile, and up to two miles, from the specific Project): (i) commence operations
at another self storage project or (ii) undertake any renovations or other
capital improvements on any property not theretofore competitive with that
specific Project which improvements would render it competitive with that
specific Project, without either: (i) the prior written consent of the Investor
Limited Partner, which may be withheld in its sole and absolute discretion, or
(ii) PSA providing to the Partnership a guarantee (in form and substance
reasonably acceptable to the Investor Limited Partner) of the budgeted operating
yield of that specific Project (as approved by the Investment Committee) through
November 17, 2006.

         7.  Books and Records; Fiscal Matters

             7.1 Books and Records. The Partnership shall keep adequate
financial books and records in accordance with generally accepted accounting
principles. The books and records shall be kept at the principal executive
office of the Partnership and shall set forth a true and accurate account of all
business transactions arising out of and in connection with the conduct of the
Partnership. Any Partner or its designated representative (including its
appointees to the Investment Committee) shall have the right, at any reasonable
time during ordinary business hours, to have access to and inspect and copy the
contents of any of the Partnership's books and records (financial or otherwise)
and records of any PSA Affiliates relating to the Projects. The Partnership
shall not, without the consent of the Partners, which shall not be unreasonably
withheld or delayed, vary the Partnership's accounting methods, change its
Fiscal Year or make other major decisions with respect to treatment of various
transactions for bookkeeping or accounting purposes.

             7.2 Reports. The General Partner shall furnish to each Partner, at
the expense of the Partnership, such statements and reports of the Partnership
as the Partners may determine or which may be required under the Act, including
the following:

                 (a) within 25 days of the end of each month, operating
statements for each of the Projects for such month, including occupancy reports,
a consolidated operating statement of the Projects for that month, a statement
detailing Partnership investment of funds and a statement detailing any
Partnership disposition of investments;

                 (b) within 40 days of the end of each of the fiscal quarters of
each Fiscal Year, a balance sheet, a profit and loss statement, a statement of
cash flows and a statement of changes in partner's capital accounts, which
statements need not be audited but shall be prepared in accordance with
generally accepted accounting principles (except that quarterly statements need
not include footnotes), and shall be certified as fairly presenting the
financial results by the chief financial officer of the General Partner;

                 (c) within 40 days of the end of each of the fiscal quarters of
each Fiscal Year, a report setting forth the variance between the Project
operating budget and actual results on a Project and consolidated basis;

                 (d) within 75 days of the end of each Fiscal Year, unaudited
financial statements of the Partnership for such Fiscal Year certified by the
General Partner; and

                 (e) within 90 days of the end of each Fiscal Year, audited
financial statements of the Partnership for such Fiscal Year certified by Ernst
& Young LLP or such other so-called "Big Six" firm of independent public
accountants as may be approved by the Investment Committee.

                 Examples of the reports required by Section 7.2(a), (b) and (c)
are attached hereto as Exhibit M.

             7.3 Tax Information. The General Partner shall cause the
Partnership accountants to prepare and file on a timely basis all income and
other tax returns of the Partnership. The General Partner shall have the
accounting firm that audits the Partnership's financial statements or another
accounting firm approved by the Investment Committee review and sign as preparer
the Partnership's Federal and state income tax returns. The General Partner
shall submit such Federal income tax returns to the Investor Limited Partner for
the Investor Limited Partner's review at least ten Business Days before filing
such returns. The General Partner shall furnish to the Investor Limited Partner
a copy of such return, together with any schedules or other information which
each Partner may reasonably require in connection with such Partner's own tax
affairs within 90 days of the end of each Fiscal Year.

             7.4 Fiscal Year. The Fiscal Year of the Partnership shall be the
calendar year.

             7.5 Tax Matters Partner. The General Partner is hereby designated
by the Partners as, and shall be specifically authorized to act as, the "Tax
Matters Partner" under the Code and in any similar capacity under state or local
law, and to expend Partnership funds for professional services and costs
associated therewith.

             7.6 Tax Elections Made by Managing Partner. The General Partner on
behalf of the Partnership may make any and all elections for tax purposes with
respect to the Partnership, with the consent of the Investor Limited Partner,
which consent will not be unreasonably withheld or delayed. At the request of
any Partner, the Partnership will make an election under Code Section 754

             7.7 Taxation as a Partnership. The Partners will use their best
efforts to cause the Partnership to be treated as a partnership for income tax
purposes.

             7.8 Avoidance of Unrelated Business Taxable Income. The General
Partner acknowledges that one or more members of the Investor Limited Partner
generally expect to be exempt from federal income taxes, and wish to avoid
receipt of income that otherwise might be considered unrelated business taxable
income. Accordingly, the General Partner shall use its best efforts to conduct
the Partnership's operations at all times in a manner that will avoid subjecting
the Investor Limited Partner or any Affiliate to regular corporate income tax or
to tax on "unrelated business taxable income" under Section 511 of the Code, and
if it is discovered that the operations of the Partnership create any such
material liability, the General Partner shall use its best efforts to alter the
Partnership's activities so as to reduce or minimize any such tax liability. In
furtherance of the foregoing (and not in limitation thereof), notwithstanding
any other provision herein to the contrary, absent specific written approval of
the Investor Limited Partner, the Partnership shall conduct its operations in
accordance with the following provisions at all times:

                 (a) The Partnership's business shall be limited to developing,
owning, operating, and disposing of the Projects, the PSA Equity Shares and the
PSA Common Shares. The Partnership shall not engage in any other business
activities.

                 (b) The Partnership shall not incur or continue any
"acquisition indebtedness" as defined in Section 514 of the Code.

                 (c) The Partnership shall be a lessor of personal property only
if the rents attributable to such personal property are an incidental amount of
the total rents received or accrued under a lease of real property within the
meaning of Section 512(b)(3)(A)(ii) of the Code.

                 (d) The Partnership's lease agreements shall not provide for
rents that depend in whole or in part on the income or profits derived by any
Person from the leased property.

                 (e) The Partnership shall not provide services to lessees of
the Projects, other than services that are usually or customarily rendered in
connection with the rental of space for occupancy only.

                 (f) The Partnership shall not hold property primarily for sale
to customers in the ordinary course of business or hold stock in trade or
property of a kind which would be included in inventory if on hand at the close
of its taxable year.

                 (g) Any sales of locks, boxes, packing or other such materials
at any Project, or any trucks rentals from any Project, will be performed for
the account of a PSA Affiliate; no such revenue will be earned by or reported by
the Partnership.

         8.  Transfer of Interests

             8.1 Transfers by the Partners during the Initial Ten Years. During
the initial ten years of the Partnership's existence, except as otherwise
provided in this Agreement, no Partner shall Transfer all or any portion of its
Interest in the Partnership without the prior written approval of the other
Partners. Notwithstanding this limitation, the General Partner and PS Limited
Partner, shall be permitted to Transfer their Interests in connection with the
merger or reorganization of the General Partner or the PS Limited Partner into
another entity which is or becomes a PSA Affiliate or the transfer of all or
substantially all the assets of, or ownership in, the General Partner or the PS
Limited Partner or the assumption of the rights and obligations of the General
Partner or the PS Limited Partner by another entity or entities which is or
becomes a PSA Affiliate in connection with any such transaction, provided that
the General Partner or PS Limited Partner, as appropriate, acknowledges that the
Transfer shall not relieve the transferring Partner of its obligations under
this Agreement. During the initial ten years a nontransferring Partner shall be
entitled to withhold its approval of any proposed Transfer in its sole
discretion.

             8.2 Additional Restrictions on Transfer. After the initial ten year
period, a Partner may transfer its interest with the prior written approval of
the other Partner, which shall not be unreasonably withheld. At any time, each
of the Partners shall have the right to Transfer its Interest to an Affiliate
without the consent of any other Partner, provided that such Transfer shall not
relieve such transferring Partner of its obligations under this Agreement.
Notwithstanding any provision of this Article 8 to the contrary, no Transfer of
any Interests may be made (i) if such Transfer shall violate or constitute a
default under any other agreement to which the Partnership is a party or (ii) if
the Interests sought to be sold, exchanged or otherwise transferred when added
to the total of all other Interests sold or exchanged prior to the date of the
proposed sale or exchange, are likely, in the opinion of tax counsel to the
Partnership to result in (A) a "change in ownership" for tax purposes as that
term is defined by applicable law or (B) the termination of the Partnership for
purposes of the Code, and such change in ownership or termination would have a
material adverse effect on the Partnership or the remaining Partners.

             No interests in the Partnership may be Transferred unless (i) the
transferee executes such instruments as the non-transferring Partner may
reasonably request to confirm the transferee's agreement to be bound by the
terms of this Agreement and assumption of the transferor's obligations under
this Agreement, (ii) the Partnership obtains assurances reasonably satisfactory
to the non-transferring Partner that such Transfer is permitted under the
Securities Act of 1933 and any applicable state securities laws, (iii) to the
extent that the transferring Partner has been informed that a Transfer might
occasion a material violation of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), to the extent applicable to the remaining Partner or
any investor in or affiliate of the remaining Partner, the transferring Partner
obtains reasonably satisfactory assurances that the transfer will not cause any
such violation and (iv) subject to the provisions of Sections 8.1 (regarding
certain transfers by the General Partner or PS Limited Partner) and 8.6
(regarding transfers to Affiliates), if the transfer involves the proposed
substitution of the transferee as a Partner of the Partnership, the written
consent of the non-transferring Partner to such substitution is obtained, which
consent, in the non-transferring Partner's absolute discretion, may be withheld.

             If one of only two Partners is transferring its entire interest in
the Partnership, such transfer shall not be effective unless and until the
transferee is admitted to the Partnership as a substitute Partner by the
amendment of this Agreement, and the transferring Partner shall remain a Partner
of the Partnership until such substitute Partner is admitted to the Partnership.
Each transferee shall reimburse the Partnership for any filing fees and
reasonable counsel and accountants' fees incurred by the Partnership in
connection with such transferee becoming a substitute Partner.

             The transferor and transferee shall furnish the Partnership with
the transferee's taxpayer identification number, sufficient information to
determine the transferee's initial tax basis in the Interest transferred, and
any other information reasonably necessary to permit the Partnership to file all
required federal and state tax returns and other legally required information
statements or returns. Without limiting the generality of the foregoing, the
Partnership shall not be required to make any distribution otherwise provided
for in this Agreement with respect to any transferred Interest until it has
received such information.

             8.3 Prohibited Transfers. Any purported Transfer of an Interest not
satisfying the requirements of Section 8.1 or 8.2 shall be null and void and of
no effect whatever; provided that, if the Partnership is required to recognize a
Transfer not satisfying those requirements, the Interest transferred shall be
strictly limited to the transferor's rights to allocations and distributions as
provided by this Agreement with respect to the transferred Interest, which
allocations and distributions may be applied (without limiting any other legal
or equitable rights of the Partnership) to satisfy any debts, obligations or
liabilities for damages that the transferor or transferee of such Interest may
have to the Partnership. Except as otherwise required under the Act, such
transferee shall have no right to any information or accounting of the affairs
of the Partnership, shall not be entitled to inspect the books or records of the
Partnership, and shall not have any of the rights of a Partner under the Act or
this Agreement until such time, if at all, that it is admitted as a Partner. In
the case of a Transfer or attempted Transfer of an Interest that is not a
permitted Transfer, the parties engaging or attempting to engage in such
Transfer shall indemnify and hold harmless the Partnership and all Partners from
all cost, liability and damage that any of such indemnified Persons may incur
(including, without limitation, incremental tax liability and attorneys' fees
and expenses) as a result of such Transfer or attempted Transfer and efforts to
enforce the indemnity granted hereby.

             8.4 Representations; Legend. Each Partner hereby represents and
warrants to the Partnership and the Partners that such Partner's acquisition of
an Interest hereunder is made as principal for such Partner's own account and
not for resale or distribution of such Interest. Each Partner further hereby
agrees that the following legend may be placed upon any counterpart of this
Agreement, or any other document or instrument evidencing ownership of
Interests:

                 The Interest represented by this document has not been
     registered under any securities laws and the transferability of such
     Interest is restricted. Such Interest may not be sold, assigned or
     transferred, nor will any assignee, vendee, transferee or endorsee thereof
     be recognized as having acquired any such Interest by the issuer for any
     purposes, unless (i) a registration statement under the Securities Act of
     1933, as amended, with respect to the transfer of such Interest shall then
     be in effect and such transfer has been qualified under all applicable
     state securities laws, or (ii) the availability of an exemption from such
     registration and qualification shall be established to the satisfaction of
     counsel to the Partnership.

                 The Interest represented by this document is subject to
     restriction as to its sale, transfer, hypothecation or assignment as set
     forth in the Limited Partnership Agreement of PSAC Development Partners,
     L.P. and agreed to by each Partner. Said provision restricts, among other
     things, the right of any transferee to become a Partner. Said Agreement
     further provides for an option to purchase the Interest represented by this
     document under certain circumstances described therein.

             8.5 Distributions and Allocations in Respect to Transferred
Interests. If any Interest is sold, assigned or transferred during any
accounting period in compliance with the provisions of this Section 8, Profits,
Losses, each item thereof and all other items attributable to the transferred
Interest for such period shall be divided and allocated between the transferor
and the transferee by taking into account their varying interests during the
period in accordance with Code Section 706(d), using any conventions permitted
by law and selected by the General Partner. All distributions on or before the
date of such transfer shall be made to the transferor, and all distributions
thereafter shall be made to the transferee. Solely for purposes of making such
allocations and distributions, the Partnership shall recognize such transfer not
later than the end of the calendar month during which it is given notice of such
transfer, provided that if the Partnership does not receive a notice stating the
date such Interest was transferred and such other information as the General
Partner may reasonably require within 30 days after the end of the accounting
period during which the transfer occurs, then all of such items shall be
allocated, and all distributions shall be made, to the Person who, according to
the books and records of the Partnership, on the last day of the accounting
period during which the transfer occurs, was the owner of the Interest. Neither
the Partnership, the General Partner nor the Partners shall incur any liability
for making allocations and distributions in accordance with the provisions of
this Section 8.5, whether or not the Partnership, the General Partner or the
Partners have knowledge of any transfer of ownership of any Interest.

         9.  Options to Cause Early Liquidation of Partnership; Options to
Purchase; Right to Cause Sale of Projects

             9.1 Investor Limited Partner's Option to Cause Early Liquidation of
the Partnership. The Investor Limited Partner shall have the right and option
(but not the obligation) to cause the early liquidation of the Partnership on
the terms and conditions set forth in this Section 9 and in Section 10. The
option granted pursuant to this Section 9.1 may be exercised by the Investor
Limited Partner at any time beginning August 17, 2005 and ending June 17, 2006
by delivery of a notice to the General Partner (the "Investor Limited Partner
Liquidation Notice"). Once given, the Investor Limited Partner Liquidation
Notice shall be irrevocable. If the Investor Limited Partner exercises this
option prior to November 17, 2005 and the General Partner does not exercise its
option to purchase the Investor Limited Partner's interest pursuant to Section
9.2: (i) any distributions of Operating Cash to be made for the period beginning
on November 17, 2005 and ending on the date of the Partnership's dissolution
shall be made to the Partners in proportion to their Percentage Interests
(rather than as described in Section 4.1(b)), and (ii) solely for the purpose of
determining Fair Market Value pursuant to Section 9.3, any guarantee provided by
PSA with respect to any Project pursuant to Section 6.4 shall be taken into
account as if that guarantee continued in perpetuity.

             9.2 General Partner's First Option to Purchase.

                 (a) If the Investor Limited Partner exercises the option set
forth in Section 9.1, the General Partner or its assignee shall have the right
and option (but not the obligation) to purchase all of the Interest of the
Investor Limited Partner on the terms and conditions set forth in this Section
9.2. The option granted pursuant to this Section may be exercised by the General
Partner by delivery of a notice to the Investor Limited Partner at any time
within 30 days of receipt of the Investor Limited Partner Liquidation Notice by
delivery of a notice to the Investor Limited Partner (the "General Partner First
Option Notice"). Once given the General Partner First Option Notice shall be
irrevocable. If the General Partner exercises its option and the General Partner
determines that it does not wish to continue to hold an ownership interest in
certain of the Projects, the Partners agree to cooperate in all reasonable
respects to have the Partnership dispose of those Projects at no cost to the
Investor Limited Partner.

                 (b) The purchase consideration payable by the General Partner
to the Investor Limited Partner shall be an amount that, when added to all
amounts distributed to the Investor Limited Partner under this Agreement
(including any guaranteed payments made under Section 2.2(e)) will equal to the
sum of the Investor Limited Partner's Capital Contributions and the aggregate
Priority Distribution of the Investor Limited Partner accrued from the Initial
Funding Date to the date of its payment, with the Priority Distribution for
purposes of this Section 9.2 and Section 12.1 computed using monthly compounding
at the monthly rate of one twelfth of 10.75% or 12% if the General Partner
exercises its right under Section 9.6 (i.e., causes a sale of one or more
Projects or shares of PSA stock without the consent of the Investor Limited
Partner). The General Partner's estimate of such purchase consideration shall be
set forth in the General Partner First Option Notice. If the Investor Limited
Partner disagrees with such estimate, the Investor Limited Partner shall notify
the General Partner, and if the parties are unable to reach agreement, the
matter will be arbitrated in accordance with Section 14.19.

             9.3 General Partner's Obligation to Purchase.

                 (a) If following the Investor Limited Partner's exercise of the
option set forth in Section 9.1, the General Partner does not exercise its
option to purchase all of the Interest of the Investor Limited Partner pursuant
to Section 9.2, the General Partner or its assignee shall purchase, and the
Investor Limited Partner shall sell, all of the Interest of the Investor Limited
Partner in accordance with the provisions of this Section 9.3.

                 (b) The purchase consideration payable by the General Partner
to the Investor Limited Partner shall be the Net Equity of the Investor Limited
Partner's Interest as determined, without audit or certification, from the books
and records of the Partnership by the firm of independent public accountants
regularly employed by the Partnership. The Net Equity of the Investor Limited
Partner's Interest to be purchased shall be determined within 15 days after such
accountants are apprised in writing of the Fair Market Value of the Property,
and the amount of such Net Equity shall be disclosed to the Partners by written
notice. The Net Equity determination of such accountants shall be final and
binding in the absence of manifest error. The Investor Limited Partner shall
have the right to cause an audit of the Net Equity determination, at the sole
expense of the Investor Limited Partner, provided that the Partnership shall pay
such expense if the audited results of the Net Equity determination result in an
increase by two percent or more in the Net Equity of the Investor Limited
Partner's Interest as compared to the unaudited amount.

                 (c) The Fair Market Value of the Property shall be determined
as follows:

                     (i) In determining the Fair Market Value of all Property of
     the Partnership, the Fair Market Value of the PSA Equity Shares and any PSA
     Common Shares shall be the Average Price multiplied by the sum of (1) the
     number of shares of PSA Common Shares into which the PSA Equity Shares held
     by the Partnership are convertible and (2) the number of shares of PSA
     Common Shares held by the Partnership. The Fair Market Value of all other
     Property (i.e., all Property other than PSA Equity Shares and PSA Common
     Shares, the "Other Property") shall be determined as set forth below.

                     (ii) The General Partner shall provide the Investor Limited
     Partner its estimate of the value of the Other Property (including a
     general explanation of how the estimated value was determined and
     calculated) within 30 days of receipt of the Investor Limited Partner
     Liquidation Notice. If the Investor Limited Partner does not provide the
     General Partner with an approval of the estimate of value within 45 days of
     receiving the General Partner's estimate of value of the Property, then
     such value shall be deemed to be rejected as its Fair Market Value.

                     (iii) If the Investor Limited Partner rejects the General
     Partner's estimate of value, then the General Partner shall engage an
     Appraiser (the "First Appraiser"). The First Appraiser's engagement shall
     require the Appraiser to determine the Appraised Value of the Other
     Property, and to submit such appraisal and determination to each of the
     General Partner and the Investor Limited Partner within 60 days of
     engagement.

                     (iv) Within 20 days after receipt of such appraisal and
     determination, the Investor Limited Partner shall notify the General
     Partner and the First Appraiser as to whether it accepts or rejects the
     Appraised Value of the Other Property. If the Investor Limited Partner
     rejects the Appraised Value of the First Appraiser, it shall engage another
     Appraiser (the "Second Appraiser") and include its name in the notice of
     rejection. In the absence of acceptance of the Appraised Value prepared by
     the First Appraiser, the Investor Limited Partner shall be deemed to have
     rejected the Appraised Value as determined by the First Appraiser. If the
     Investor Limited Partner accepts the Appraised Value of the First
     Appraiser, then such value shall be deemed the Fair Market Value.

                     (v) The Second Appraiser's engagement shall require the
     Appraiser to determine the Appraised Value of the Other Property, and to
     submit such appraisal and determination to each of the General Partner and
     the Investor Limited Partner within 60 days of engagement.

                     (vi) If the lower of the Appraised Values determined by the
     First and Second Appraisers is at least 90% of the higher of those two
     Appraised Values, then the Fair Market Value shall be the average of those
     two Appraised Values. If the difference between the Appraised Values is
     greater than 10%, then the First Appraiser and the Second Appraiser shall
     engage another Appraiser (the "Third Appraiser") to determine the Appraised
     Value of the Other Property, and to submit such appraisal and determination
     to each of the General Partner and the Investor Limited Partner within 60
     days of engagement.

                     (vii) If a Third Appraiser is so engaged, the average of
     the highest Appraised Value and the lowest Appraised Value shall be
     determined. If the remaining Appraised Value (the Appraised Value that is
     in between the highest and the lowest) is no more than 5% greater than, and
     no more than 5% less than, the average of the highest and the lowest, the
     Fair Market Value shall be the average of the highest and lowest Appraised
     Values. If the middle Appraised Value is outside of that range, the Fair
     Market Value shall be the average of the two Appraised Values that are
     closest to each other.

                     (viii) All costs of any appraisal process shall be borne
     50% by the General Partner and 50% by the Investor Limited Partner.

                 (d) If the Investor Limited Partner's Net Equity with respect
to the Interest purchased, combined with all prior distributions received by the
Investor Limited Partner, produces a Shortfall as defined in Section 1.8(mmm),
the purchase consideration payable by the General Partner to the Investor
Limited Partner in respect of the Interest purchased pursuant to Section 9.2
shall include an amount equal to the Shortfall.

             9.4 No Exercise of Option to Cause Early Liquidation of the
Partnership; General Partner's Second Option to Purchase.

                 (a) The General Partner or its assignee shall have the right
and option (but not the obligation) to purchase all of the Interest of the
Investor Limited Partner on the terms and conditions set forth in this Section
9.4. The option granted pursuant to this Section may be exercised by the General
Partner by delivery of a notice (the "General Partner Second Option Notice") to
the Investor Limited Partner at any time beginning 60 days prior to November 17,
2014. Once given the General Partner Second Option Notice shall be irrevocable.
If the General Partner exercises its option and the General Partner determines
that it does not wish to continue to hold an ownership interest in certain of
the Projects, the Partners agree to cooperate in all reasonable respects to have
the Partnership dispose of those Projects, at no cost to the Investor Limited
Partner.

                 (b) The purchase consideration payable by the General Partner
to the Investor Limited Partner shall be the Net Equity of the Investor Limited
Partner's Interest as of November 17, 2014, determined as provided in Section
9.3(b).

             9.5 Closing. The closing of the purchase and sale of the Investor
Limited Partner's Interest under Section 9.2, 9.3 or 9.4 shall occur at the
principal executive office of the Partnership on a date and time mutually
agreeable to the General Partner and the Investor Limited Partner, which shall
not be later than 20 days following the determination of the Net Equity of the
Investor Limited Partner Interest (subject to final determination of the
component of Net Equity that is based on the Average Price). At the closing, the
Investor Limited Partner will deliver or cause to be delivered to the General
Partner (i) appropriate assignments or other documents sufficient to transfer
good and valid title to the Interest to be purchased, free and clear of all
liens and encumbrances; and (ii) such other documents as the General Partner or
its counsel may reasonably request. At the closing, the General Partner will
deliver or cause to be delivered to the Investor Limited Partner a wire transfer
of immediately available funds in the amount to which the Investor Limited
Partner is entitled under this Agreement.

             9.6 General Partner Right to Compel Sale. Notwithstanding anything
in this Agreement to the contrary, the General Partner shall have the right to
compel the sale of all or any number of the Projects or shares of PSA Equity
Shares or PSA Common Shares to a third party for cash at no less than fair
market value without the consent of the Limited Partners at any time and from
time to time. In such event, the net proceeds of any such sale or sales shall be
invested in obligations of the United States Treasury.

         10. Dissolution and Winding Up

             10.1 Liquidating Events. The Partnership shall dissolve and
commence winding up and liquidating upon the first to occur of any of the
following (a "Liquidating Event"):

                 (a) The sale of all or substantially all of the Property (other
than a sale pursuant to Section 9.6);

                 (b) The vote by the General Partner and 100% in Percentage
Interest of the Partners to dissolve, wind up and liquidate the Partnership;

                 (c) The Investor Limited Partner's exercise of the option to
cause liquidation provided in Section 9.1 followed by the subsequent failure of
the General Partner to exercise the option to purchase provided in Section 9.2
by the end of the period specified therein and the then subsequent failure of
the General Partner to perform its obligation to purchase pursuant to Section
9.3;

                 (d) The occurrence of any of the events specified in Section
15681 of the Act; or

                 (e) 5:00 p.m., Pacific time, November 17, 2014.

             10.2 Winding Up. Upon the occurrence of a Liquidating Event, the
Partnership shall continue solely for the purposes of winding up its affairs in
an orderly manner, liquidating its assets and satisfying the claims of its
creditors and Partners. In such event, no Partner shall take any action that is
inconsistent with, or not necessary to or appropriate for, the winding up of the
Partnership's business and affairs. The General Partner (or, in the event that
either the General Partner is in material default under this Agreement and the
default continues after reasonable notice and opportunity to cure or there is no
General Partner, any Person elected by a majority in Percentage Interest of the
Partners) shall be responsible for overseeing the winding up and dissolution of
the Partnership and shall take full account of the Partnership's liabilities and
Property and the Property shall be liquidated as promptly as is consistent with
obtaining the fair value thereof, and the proceeds therefrom, to the extent
sufficient therefor, shall be applied and distributed in the following order:

                 (a) First, to the payment and discharge of all of the
Partnership's debts and liabilities to creditors other than the Partners;

                 (b) Second, to the payment and discharge of all of the
Partnership's debts and liabilities to the Partners; and

                 (c) The balance, if any, to the Partners in accordance with
their Capital Accounts, after giving effect to all contributions, distributions
and allocations for all periods (other than distributions and contributions made
pursuant to this Section 10.2(c) and deductions attributable thereto); provided,
however, that if: (i) the Liquidating Event occurs on or before November 17,
2005, (ii) prior to making the distributions pursuant to this Section 10.2(c),
the General Partner and the PS Limited Partner combined have a positive Capital
Account, and (iii) the distribution that otherwise would be made to the Investor
Limited Partner would result in a Shortfall, an amount otherwise distributable
to the General Partner and the PS Limited Partner combined pursuant to this
Section 10.2(c) equal to the amount of the Shortfall shall be deemed
recontributed by the General Partner and the PS Limited Partner (in a 1/50
ratio, or if different, in the ratio in which they otherwise would share the
distribution) to the Partnership and shall be distributed to the Investor
Limited Partner as a guaranteed payment pursuant to Section 2.2(e).

             10.3 Compliance with Timing Requirements of Regulations. In the
event the Partnership is "liquidated" within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g), (a) distributions shall be made pursuant to this Section
10 to the Partners who have positive Capital Accounts in compliance with
Regulations Section 1.704-1(b)(2)(ii)(b)(2), and (b) if a Partner's Capital
Account has a deficit balance (after giving effect to all contributions,
distributions and allocations for all taxable years, including the year during
which such liquidation occurs), such Person shall have no obligation to make any
contribution to the capital of the Partnership with respect to such deficit, and
such deficit shall not be considered a debt owed to the Partnership or any other
Person for any purpose whatsoever. In the discretion of the General Partner, a
pro rata portion of the distributions that would otherwise be made to the
Partners pursuant to this Section 10 may be:

                 (a) Distributed to a trust established for the benefit of the
Partners for the purposes of liquidating Partnership assets, collecting amounts
owed to the Partnership, and paying any contingent or unforeseen liabilities or
obligations of the Partnership or of the Partners arising out of or in
connection with the Partnership. The assets of any such trust shall be
distributed to the Partners from time to time, in the reasonable discretion of
the General Partner, in the same proportions as the amount distributed to such
trust by the Partnership would otherwise have been distributed to the Partners
pursuant to this Agreement; or

                 (b) Withheld to provide a reasonable reserve for Partnership
liabilities (contingent or otherwise) and to reflect the unrealized portion of
any installment obligations owed to the Partnership, provided that such withheld
amounts shall be distributed to the Partners as soon as practicable.

             10.4 Rights of Partners. Except as otherwise provided in this
Agreement each Partner shall look solely to the assets of the Partnership for
the return of its Capital Contribution and shall have no right or power to
demand or receive property other than cash from the Partnership.

         11. Indemnification

             11.1 Indemnification by the Partnership. The Partnership shall
indemnify and hold harmless the Partners, their Affiliates, the Investor Limited
Partner's advisor, and their respective officers, directors, employees, agents
(including members of the Investment Committee) and principals (for purposes of
this Section, an "Indemnitee") from and against any and all losses, claims,
demands, costs, damages, liabilities, joint and several, expenses of any nature
(including reasonable attorneys' fees and disbursements), judgments, fines,
settlements and other amounts arising from any and all claims, demands, actions,
suits or proceedings, whether civil, criminal, administrative or investigative,
in which the Indemnitee was involved or may be involved, or threatened to be
involved, as a party or otherwise, arising out of or incidental to the business
of the Partnership, excluding liabilities to any Partner, regardless of whether
the Indemnitee continues to be a Partner, an Affiliate, or an officer, director,
employee, agent or principal of the Partner at the time any such liability or
expense is paid or incurred, to the fullest extent permitted by the Act and all
other applicable laws; provided that such indemnity shall not extend to actions
or omissions in bad faith or constituting gross negligence by any such
Indemnitee and shall not extend to actions taken by the property manager (which
is indemnified under the Management Agreement) in its capacity as such pursuant
to the Management Agreement. Further, this Section shall not operate to
indemnify or hold harmless the General Partner or any other PSA Affiliate for
acts or omissions to the extent the General Partner is liable for those acts or
omissions pursuant to Section 11.2.

             Without limitation to any other exculpatory provision of this
Agreement, the Investor Limited Partner and its representatives (including its
appointees to the Investment Committee) shall not have any fiduciary obligation
to, or any other obligation to act in the interests of, any other Partner or the
Partnership by virtue of their respective rights under this Agreement or any
guaranty by PSA, including, without limitation, their respective rights under
Sections 1.7 (certain rights of first refusal to develop Qualifying Properties),
6.2 (activities of the Investment Committee) or 6.3 (opportunity to invest in
next development program) or Article 9 (certain options to purchase Interests)
of this Agreement, or in the exercise of such rights.

             11.2 Indemnification by the General Partner. The General Partner
shall indemnify and hold harmless the Investor Limited Partner, the Partnership,
and their respective Affiliates, advisors, officers, directors, employees,
agents (including members of the Investment Committee) and principals (for
purposes of this Section, an "Indemnitee") from and against any and all losses,
claims, demands, costs, damages, liabilities, joint and several, expenses of any
nature (including reasonable attorneys' fees and disbursements), judgments,
fines, settlements and other amounts arising from (i) any and all claims,
demands, actions, suits or proceedings, whether civil, criminal, administrative
or investigative, in which the Indemnitee was involved or may be involved, or
threatened to be involved, as a party or otherwise, arising out of a violation
or alleged violation of federal or state securities laws incurred in connection
with the purchase or sale of, or any other transaction involving, PSA Common
Shares or PSA Equity Shares of the Partnership, (ii) any demands, claims
actions, suits or proceedings by any third party asserting a right of first
refusal or other like right to undertake the acquisition or development of
self-storage facilities with any PSA Affiliate that conflicts with the rights
granted to the Partnership pursuant to Section 1.7, or (iii) acts or omissions
in bad faith or constituting gross negligence by the General Partner or any of
its Affiliates, directors, officers, employees, agents, and principals, in any
case, regardless of whether the Indemnitee continues to be the Investor Limited
Partner, an Affiliate, or an officer, director, employee, agent or principal of
the Investor Limited Partner at the time any such liability or expense is paid
or incurred, to the fullest extent permitted by the Act and all other applicable
laws, provided that such indemnity shall not extend to actions not taken in good
faith by any such Indemnitee.

             11.3 Expenses.. Expenses incurred by an Indemnitee in defending any
claim, demand, action, suit or proceeding subject to Sections 11.1 or 11.2
shall, from time to time, be advanced by the Partnership prior to the final
disposition of such claim, demand, action, suit or proceeding upon receipt by
the Partnership of an undertaking by or on behalf of the Indemnitee to repay
such amount if it shall be determined that such Person is not entitled to be
indemnified as authorized in Sections 11.1 or 11.2.

             11.4 Indemnification Rights Nonexclusive. The indemnification
provided by Sections 11.1 or 11.2 shall be in addition to any other rights to
which those indemnified may be entitled under any agreement, vote of the
Partners, as a matter of law or equity or otherwise, both as to action in the
Indemnitee's capacity as a Partner, the General Partner, an Affiliate or an
officer, director, employee, agent or principal of a Partner and as to any
action in another capacity, and shall continue as to an Indemnitee who has
ceased to serve in such capacity and shall inure to the benefit of the heirs,
successors, assigns and administrators of the Indemnitee.

             11.5 Errors and Omissions Insurance. The Partnership may purchase
and maintain insurance, at the Partnership's expense, on behalf of the
Partnership, the General Partner, the Partners and such other Persons as the
General Partner shall determine (provided that the Partners and other Persons
shall only be named as insured to the extent that doing so does not increase the
cost of the insurance or if any added cost is borne by the affected Person),
against any liability that may be asserted against, or any expense that may be
incurred by, such Person in connection with the activities of the Partnership
and/or the General Partner's or the Partners' acts or omissions as the General
Partner and Partners of the Partnership regardless of whether the Partnership
would have the power to indemnify such Person against such liability under the
provisions of this Agreement.

             11.6 Assets of the Partnership. Any indemnification under Section
11.1 shall be satisfied solely out of the assets of the Partnership. No Partner
shall be subject to personal liability or required to fund or to cause to be
funded any obligation by reason of Section 11.1's indemnification provisions.

         12. Defaulting Event Remedies

             12.1 Election to Purchase Defaulting Partner's Interest. In the
event that a Partner becomes a Defaulting Partner, the nondefaulting Partner
shall have the option to purchase the Interest of the Defaulting Partner in the
Partnership, with any such election to be made by the nondefaulting Partner
giving notice of such election to the Defaulting Partner within 30 days after
the nondefaulting Partner first discovers that the other Partner has become a
Defaulting Partner (and so notifies the Defaulting Partner in writing). In the
event that the General Partner is the Defaulting Partner and shall at that time
be able to exercise the option to purchase the Interest of the Investor Limited
Partner under Section 9.2, then the General Partner can exercise its Section 9.2
option within 30 days after such notice, provided that the closing under Section
9.5 shall take place within 20 days following the date of exercise of such
option.

             12.2 Purchase Price of Defaulting Partner's Interest. If either
Partner becomes a Defaulting Partner, in the event that the nondefaulting
Partner elects under Section 12.1 to purchase the Defaulting Partner's Interest,
the purchase price of such Interest shall be 70% of the Adjusted Capital
Contribution of the Defaulting Partner; provided, however, that the
nondefaulting Partner shall receive a credit against such purchase price in the
amount of any delinquent capital contributions due from the Defaulting Partner
and any expenses of closing such purchase. This option to purchase the interest
of the Defaulting Partner at a discount is deemed reasonable by the Partners and
is intended to serve as agreed upon liquidated damages and not as a penalty, the
amount of the actual damages suffered by the nondefaulting partner being
difficult if not impossible to ascertain. In the event that the nondefaulting
Partner elects under Section 12.1 to purchase the Defaulting Partner's Interest,
then the Partnership shall not make any distributions on or before the closing
of the purchase of such Interest, and any such distributions which would have
been made to the Defaulting Partner shall be distributed to the nondefaulting
Partner on or after the closing. At such time as the purchase price of the
Defaulting Partner's Interest has been determined, the nondefaulting Partner
shall give notice of the amount thereof to the Defaulting Partner and the
closing shall be held on a date selected by the nondefaulting Partner within ten
Business Days thereafter.

             12.3 Remedies Nonexclusive. The option of the nondefaulting Partner
to purchase the Interest of the Defaulting Partner under Section 12.1 is not the
exclusive remedy of the nondefaulting Partner, but it is merely cumulative of,
and in addition to, any rights or remedies which the nondefaulting Partner or
the Partnership may have at law or in equity against or with respect to such
Defaulting Partner, provided that any recovery under this Agreement against a
Defaulting Partner shall be limited to the Defaulting Partner's interest in the
Partnership. Without limiting its right to seek and recover damages for the
Defaulting Event, a nondefaulting Partner may at its option: (i) replace the
Defaulting Partner's representative(s) on the Investment Committee with its own
representative(s), provided that no purchase, sale or financing of Property,
other than pursuant to Section 12.2, shall be taken except with the consent of
the Partners, (ii) remove the General Partner, (iii) terminate the Management
Agreement (Exhibit D) or (iv) apply to any Capital Contribution with respect to
which the General Partner is in default the management fees otherwise payable to
PSA Affiliates under the Management Agreement for a period of up to 120 days,
during which the PSA Affiliates shall not terminate the Management Agreement for
nonpayment of such management fees.

         13. Representations and Warranties

             13.1 Representations and Warranties of the General Partner. The
General Partner and the PS Limited Partner hereby represent and warrant to the

existing limited partnership in good standing under the laws of the State of
Texas, duly qualified to do business in all states in which the General Partner
is required to so qualify (except where the failure to so qualify would not have
a material adverse effect on either the General Partner's ability to perform its
obligations under this Agreement or its financial condition), and has the
requisite power and authority to enter into and carry out the terms of this
Agreement, and the PS Limited Partner is a duly organized and validly existing
business trust in good standing under the laws of the State of Delaware, duly

material adverse effect on either the PS Limited Partner's ability to perform
its obligations under this Agreement or its financial condition), and has the
requisite power and authority to enter into and carry out the terms of this
Agreement;

                 (b) All action required to be taken by the General Partner and
the PS Limited Partner to consummate this Agreement has been taken by the
General Partner and the PS Limited Partner and no further approval of any board,
court or other body is necessary in order to permit the General Partner and the
PS Limited Partner to consummate this Agreement;

                 (c) Neither the execution and delivery of, nor the performance
of, nor the compliance with, this Agreement has resulted (or will result) in any
violation of, be in conflict with, invalidate, cancel or make inoperative
interfere with, or constitute a default under, or result in the creation of any
lien, encumbrance or any other charge upon the Project (each reference in this
Section 13.1 to a Project refers to each of the Projects described on Exhibit A
and shall be deemed reconfirmed by the General Partner and the PS Limited
Partner as to each additional Project as same is acquired by the Partnership) or
the other Property, pursuant to any charter, bylaw, venture agreement,
partnership agreement, trust agreement, mortgage, deed of trust, indenture,
contract, agreement, permit, judgment, decree or order to which the General

dissolution or liquidation thereof; that it has all requisite authorizations to
enter into this Agreement with the General Partner and to consummate the
transactions contemplated hereby; and that the parties executing this Agreement
on behalf of the Investor Limited Partner are duly authorized to so do.

             13.3 Agreements of the General Partner.

                 (a) During the term of the Partnership, the Projects shall be
operated and managed as an integral part of the Public Storage network of
self-storage facilities, subject to the terms of the Management Agreement.
Without limiting the foregoing, the General Partner covenants and agrees that
the Projects will be managed in a reasonable commercial manner consistent with
the management of other self-storage projects owned by PSA Affiliates; this will
include (i) causing all rents and other charges with respect to the Projects to
be at competitive rates within the local market, taking into account occupancy,
location, the quality of the Project and all other relevant factors; (ii)
operating the Projects in a manner so as to minimize expenses applicable thereto
to the extent appropriate in the operation and promotion of first class
self-storage projects and maximizing the long term net profits therefrom and the
value thereof; and (iii) operating the Projects in a prudent and first class
manner, with all appropriate action being taken to protect and preserve them
(including appropriate repairs, maintenance, insurance coverage and the like).

                 (b) The General Partner will insure and keep insured at all
times all of the Projects (including the Partnership as a named insured) against
loss or damage by fire and from other causes customarily insured against by
companies engaged in similar businesses in such amounts as are usually insured
against by such companies, and in any case as are adequate to provide reasonable
protection against such loss or damage to the Projects. The General Partner also
will maintain at all times (including the Partnership as a named insured) with
financially sound and reputable insurers adequate insurance against loss or
damage from such hazards and risks to the person and property of others as are
usually insured against by companies operating businesses similar to the
businesses of the Partnership. All such insurance shall be carried with
financially sound and reputable insurers accorded a rating of "A-VI" or better
by A.M. Best Company, Inc. (or a comparable rating by any comparable rating
agency), provided that at least 75% of all coverage and the insurer with the
risk of first loss in each category shall have a rating of "A-IX" or better. If
the Partnership cannot obtain sufficient insurance which meets the above
criteria, the General Partner will provide the Investor Limited Partner with
notice and will demonstrate that insurance cannot be obtained in accordance with
the above criteria, in which case the requirement shall be reduced to the
highest rating for which coverage is reasonably available. The sum of the
deductible limit of all insurance coverage plus any amounts of self-insurance
will not exceed $1,500,000 per occurrence. A summary of insurance presently in
force has been provided to the Investor Limited Partner and is attached hereto
as Exhibit L.

                 (c) Expenses incurred in operating the Projects shall be
allocated among the Projects on the same basis on which such expenses are
allocated among all other projects owned by PSA Affiliates and in a manner
generally consistent with prior practice as reflected in Exhibit J.

                 (d) The General Partner shall allocate to the Partnership only
such amount of the compensation of each project manager of a Project as is
comparable to the compensation of project managers of similar sized self storage
facilities in the same or similar market areas that do not include retail
stores.

parties hereto arises out of or relating to this Agreement or the enforcement,
interpretation, performance or breach of this Agreement or as to any matters
related to but not covered by this Agreement, the parties shall first consult
together, at both the working and senior management levels, in good faith to
find an amicable resolution of the dispute or controversy. If the parties cannot
resolve the dispute or controversy by such consultation, it shall be finally
resolved by binding arbitration to be held in the County of Los Angeles, State
of California, under auspices of, and in accordance with, the Commercial
Arbitration Rules (the "Rules") of the American Arbitration Association. There
shall be an arbitral tribunal consisting of three neutral arbitrators, selected
according to the procedures set forth in the Rules and this Section, one of
which shall be selected jointly by the General Partner and the PS Limited
Partner, one of which shall be selected by the Investor Limited Partner, and the
two arbitrators so selected shall mutually appoint a third arbitrator. If either
of the first two arbitrators is not appointed within thirty (30) days of
delivery of notice of demand for arbitration, the other party (or parties) shall
select the arbitrator that was to be selected by such delinquent party (or
parties). If the first two arbitrators fail to select the third arbitrator
within thirty (30) days of their selection then, at the request of any party,
the third arbitrator shall be selected by the Chief Judge of the United States
District Court for the Central District of California (the "Court"). In any such
arbitration proceedings, the arbitrators shall adopt and apply the provisions of
the Federal Rules of Civil Procedure relating to discovery so that each party
shall allow and may obtain discovery of any matter not privileged that is
relevant to the subject matter involved in the arbitration to the same extent as
if such arbitration were a civil action pending in the Court. The arbitrators
may proceed to an award notwithstanding the failure of any party to participate
in the proceedings. The arbitrators may issue decisions for interim,
interlocutory, provisional or partial relief (e.g., temporary restraining
orders, preliminary injunctions, orders to compel discovery, orders of
attachment or protective orders) during the arbitration proceedings which may be
enforced in any court of competent jurisdiction. The arbitrators may also grant
appropriate relief at law or in equity, including removing the General Partner,
in the event the General Partner (with the participation or acquiescence of its
senior management) has been guilty of fraud, bad faith, gross negligence, abuse
of authority or misappropriation or waste of Partnership assets. The decision of
a majority of the arbitrators shall constitute an arbitral award which is final,
conclusive and binding on each party, and may be entered and shall be
enforceable in any court of competent jurisdiction.

             14.20 Confidentiality The Partners agree that the terms of this
Agreement, any other agreements entered into in connection with the transactions
contemplated hereby and the identities of the parties hereto and their parent
companies are confidential and shall not be disclosed to any third party without
the other party's prior written consent; provided, however, that any party may
disclose the existence and/or terms and conditions hereof if so required by law
or by applicable stock exchange rules or to such party's attorneys, accountants
and other professionals subject to the professional duty not to disclose such
existence and/or terms and conditions unless permitted by law, so long as such
party first provides a copy of any such written request to the other party.
