such Collateral at such time, provided that if interest on such liability is not required to be paid at least annually or if the documents evidencing such liability permit the borrower to borrow additional amounts that are secured by the
Collateral, the outstanding principal amount of such liability shall include the maximum amount that could be so added to the principal amount of such liability without a default, provided, however, if notwithstanding the Operating
Partnership’s commercially reasonable efforts, it is unable to make available the Guarantee Opportunities required by this Agreement, 130% shall be substituted for 140% as set forth above;

 For
purposes of determining whether clause (ii) has been satisfied in situations where one or more potential Approved Liabilities are secured by more than one item of Collateral, the Operating Partnership shall allocate such liabilities among such
items of Collateral in proportion to their relative fair market values (as reasonably determined in good faith by the Operating Partnership);

(i) is not secured by any of the assets of the Operating Partnership and is a general, recourse obligation of the Operating Partnership,

rise to such payment under Section 2.2, Section 2.4 or Section 2.5 occurred. Notwithstanding the foregoing, if a Protected Partner, Guaranty Partner or Non-Qualified Liability Partner demonstrates to the reasonable satisfaction
of the Operating Partnership that such Protected Partner, Guaranty Partner or Non-Qualified Liability Partner, as applicable, is not entitled to a Federal income tax deduction for all or a portion of the income taxes paid to a state or locality, the

take for such taxes.

ARTICLE II 

TAX PROTECTIONS 

Section 2.1 Taxable Transfers. 

(a) Unless the Partners’ Representative expressly consents in writing to a Tax Protection Period Transfer (for the avoidance of
doubt, no vote in favor of a Tax Protection Period Transfer by the Partners’ Representative or any of its Affiliates or by a Protected Partner, in each case in its capacity as owner shares of the REIT or OP Units, shall constitute consent),
during the Tax Protection Period, the Operating Partnership shall indemnify the Protected Partners as set forth in Section 2.2 if the Operating Partnership or any entity in which the Operating Partnership holds a direct or indirect interest
shall cause or permit (i) any Transfer of all or any portion of a Protected Property (including any interest therein or in the entity owning, directly or indirectly, the Protected Property) in a transaction that would result in the recognition
of taxable income or gain by any Protected Partner under Section 704(c) of the Code, or (ii) any Fundamental Transaction that would result in the recognition of taxable income or gain to any Protected Partner (a Fundamental Transaction and
a Transfer, collectively a “Tax Protection Period Transfer”). 
  

 7 

 (b) Section 2.1(a) shall not apply to any Tax Protection Period Transfer of a
Protected Property (including any interest therein or in the entity owning, directly or indirectly, the Protected Property): (i) in a transaction in which no gain is required to be recognized by a Protected Partner (an
“Exchange”), including a transaction qualifying under Section 1031 or Section 721 (or any successor statutes) of the Code; provided, however, that any property acquired by the Operating Partnership in the
Exchange shall remain subject to the provisions of this Article II in place of the exchanged Protected Property for the remainder of the Tax Protection Period; (ii) as a result of the condemnation or other taking of any Protected
Property by a governmental entity in an eminent domain proceeding or otherwise, provided that the Operating Partnership shall use commercially reasonable efforts to structure such disposition as either a tax-free like-kind exchange under
Section 1031 or a tax-free reinvestment of proceeds under Section 1033, provided that in no event shall the Operating Partnership be obligated to acquire or invest in any property that it otherwise would not have acquired or invested in.

 (c) For any taxable Transfer of all or any portion of any property of the Operating Partnership which is not a Tax
Protection Period Transfer, the Operating Partnership shall use commercially reasonable efforts to cooperate with the Limited Partners to minimize any taxes payable by the Limited Partners in connection with any such Transfers. 

Section 2.2 Indemnification for Taxable Transfers. 

(a) In the event of a Tax Protection Period Transfer described in Section 2.1(a), each Protected Partner shall, within 30 days
after the closing of such Tax Protection Period Transfer, receive from the Operating Partnership an amount of cash equal to the estimated Make Whole Amount applicable to such Tax Protection Period Transfer. If it is later determined that the true
Make Whole Amount applicable to a Protected Partner exceeds the estimated Make Whole Amount applicable to such Protected Partner, then the Operating Partnership shall pay such excess to such Protected Partner within 90 days after the closing of the
Tax Protection Period Transfer, and if such estimated Make Whole Amount exceeds the true Make Whole Amount, then such Protected Partner shall promptly refund such excess to the Operating Partnership, but only to the extent such excess was actually
received by such Protected Partner. 
 (b) Notwithstanding any provision of this Agreement to the contrary, the sole and
exclusive rights and remedies of any Protected Partner under Section 2.1(a) shall be a claim against the Operating Partnership for the Make Whole Amount as set forth in this Section 2.2, and no Protected Partner shall be entitled to
pursue a claim for specific performance of the covenants set forth in Section 2.1(a) or bring a claim against any person that acquires a Protected Property from the Operating Partnership in violation of Section 2.1(a). 

Section 2.3 Section 704(c) Gains. A good faith estimate of the initial amount of Section 704(c) gain allocable to each
Protected Partner as of the Closing Date of each OP Merger is set forth on Exhibit B hereto. The parties acknowledge that the initial amount of such Section 704(c) gain may be adjusted over time as required by Section 704(c) of the
Code and the Regulations promulgated thereunder.

 Section 2.4 Approved Liability Maintenance and Allocation. 

(a) During the Tax Protection Period, the Operating Partnership shall: (1) maintain on a continuous basis an amount of Approved
Liabilities at least equal to the Required Liability Amount; and (2) provide the Partners’ Representative, promptly upon request, with a description of the nature and amount of any Approved Liabilities that are available to be guarantied
by the Guaranty Partners pursuant to Section 2.4(b) of this Agreement. For the avoidance of doubt, and notwithstanding any other provision of this Agreement, the Operating Partnership shall not be required to maintain any amount of Approved
Liabilities in excess of the aggregate Required Liability Amount of all Guaranty Partners. 
 (b) (i) During the Tax Protection
Period, the Operating Partnership shall provide each Guaranty Partner with the opportunity to execute a guaranty, substantially in the form attached hereto as Exhibit F or otherwise in a form and manner that is reasonably acceptable to the
Partners’ Representative, of one or more Approved Liabilities that are Guaranty Permissible Liabilities in an amount up to such Guaranty Partner’s Required Liability Amount (each such opportunity and each opportunity required by Section
2.4(c), Section 2.5(b), and Section 2.5(c), a “Guaranty Opportunity”), and (ii) after the Tax Protection Period, and for so long as a Guaranty Partner has not had a 50% Termination, the Operating Partnership
shall use commercially reasonable efforts to make Guaranty Opportunities available to each Guaranty Partner, provided that in the case of this clause (ii), the Operating Partnership shall not be required to incur any indebtedness that it would not
otherwise have incurred, as determined by the Operating Partnership in its reasonable discretion; provided, however, that in the case of clauses (i) and (ii) the aggregate amount of all guaranties required to be made available by
the Operating Partnership for execution by all Guaranty Partners need not exceed the aggregate Required Liability Amount of all Guaranty Partners. The Operating Partnership shall have the discretion to identify the Approved Liability or Approved
Liabilities that shall be made available for guaranty by each Guaranty Partner. Each Guaranty Partner and its indirect owners may allocate the Guaranty Opportunity afforded to such Guaranty Partner in any manner they choose. The Operating
Partnership agrees to file its tax returns allocating any debt subject to a Guaranty to the applicable Guaranty Partners. Each Guaranty Partner shall bear the costs incurred by it in connection with the execution of any guaranty to which it is a
party. To the extent a Guaranty Partner executes a guaranty, the Operating Partnership shall deliver a copy of such guaranty to the lender under the Guarantied Liability promptly after receiving such copy from the relevant Guaranty Partner.

 (c) During the Tax Protection Period, the Operating Partnership shall not allow a Debt Notification Event to occur unless
the Operating Partnership provides at least thirty (30) days’ written notice (a “Section 2.4 Notice”) to each Guaranty Partner that may be affected thereby. The Section 2.4 Notice shall describe the Debt Notification
Event and designate one or more Approved Liabilities that may be guarantied by the Guaranty Partners pursuant to Section 2.4(b) of this Agreement in an amount equal to the amount of the refinanced or repaid Approved Liability that was
guarantied by such Guaranty Partner immediately prior to the date of the refinancing or repayment. Any Guaranty Partner that desires to execute a guaranty following the receipt of a Section 2.4 Notice shall provide the Operating Partnership
with notice thereof within fifteen (15) days after the date of the Section 2.4 Notice. 
 (d) Provided the Operating
Partnership satisfies its obligations under Section 2.4(a), (b) and (c) of this Agreement, it shall have no liability to a Guaranty Partner 

 

 9 

 
under Section 2.4(e) for breach of Section 2.4, whether or not such Guaranty Partner accepts its Guaranty Opportunity. Furthermore, the Operating Partnership makes no representation
or warranty to any Guaranty Partner concerning the treatment or effect of any guaranty under Federal, state, local, or foreign tax law, and bears no responsibility for any tax liability of any Guaranty Partner or Affiliate thereof that is
attributable to a reallocation, by a taxing authority, of debt subject to a guaranty (other than a reallocation that results from any act or omission taken by the Operating Partnership or one of its Affiliates in violation of this Section 2.4
or an act or omission that is indemnifiable under Section 2.4(e) of this Agreement). 
 (e) If the Operating Partnership
shall fail to comply with any provision of this Section 2.4, the Operating Partnership shall pay, within thirty (30) days of such failure, a Make Whole Payment to each Guaranty Partner who recognizes income or gain as a result of such
failure equal to the estimated Make Whole Amount applicable to such failure. If it is determined that the true Make Whole Amount applicable to a Guaranty Partner exceeds the estimated Make Whole Amount applicable to such Guaranty Partner, then the
Operating Partnership shall pay such excess to such Guaranty Partner within thirty (30) days after the date of such determination, and if such estimated Make Whole Amount exceeds the true Make Whole Amount, then such Guaranty Partner shall pay
such excess to the Operating Partnership within thirty (30) days after the date of such determination, but only to the extent such excess was actually received by such Guaranty Partner. 

(f) Notwithstanding any provision of this Agreement to the contrary, the sole and exclusive rights and remedies of any Guaranty Partner
for a breach or violation of the covenants set forth in Section 2.4 shall be a claim a claim against the Operating Partnership for the Make Whole Amount as set forth in Section 2.4(e), and no Guaranty Partner shall be entitled to
pursue a claim for specific performance of the covenants set forth in Section 2.4. 
 (g) Notwithstanding any provision
of this Section 2.4 to the contrary, to the extent a Guaranty Partner is also a Non-Qualified Liability Partner that has guaranteed Non-Qualified Liabilities pursuant to Section 2.5, the amount of such guaranteed liabilities shall be
treated as the Operating Partnership’s satisfaction of that amount of its obligation to provide a Guaranty Opportunity under this Section 2.4, and such liabilities shall be treated as an Approved Liability for purposes of this Section
2.4, including for purposes of determining whether a Section 2.4 Notice and substitute Approved Liability are required. 

Section 2.5 Non-Qualified Liability Maintenance and Allocation. 

(a) During the Non-Qualified Liability Period, the Operating Partnership shall not repay any Non-Qualified Liability (excluding any
scheduled payments of principal occurring pursuant to the terms of such Non-Qualified Liability) which has been guarantied by a Non-Qualified Liability Partner pursuant to Section 2.5(b) unless: (i) the Operating Partnership repays such
Non-Qualified Liability with proceeds generated by its incurrence of other liabilities which each such Non-Qualified Liability Partner is offered an opportunity to guaranty; or (ii) the Partners’ Representative consents in writing to such
repayment. 
  

 10 

 (b) During the Non-Qualified Liability Period, the Operating Partnership shall use
commercially reasonable efforts to provide each Non-Qualified Liability Partner with the opportunity to execute a guaranty, substantially in the form attached hereto as Exhibit F or otherwise in a form and manner that is reasonably acceptable
to the Partners’ Representative, of each Non-Qualified Liability listed below such Non-Qualified Liability Partner’s name in Exhibit E in an amount up to such Non-Qualified Liability Partner’s Non-Qualified Liability Amount.
Each Non-Qualified Liability Partner and its indirect owners may allocate the Guaranty Opportunity afforded to such Non-Qualified Liability Partner in any manner they choose. The Operating Partnership agrees to file its tax returns allocating any
Guarantied Liability to the applicable Non-Qualified Liability Partners. Each Non-Qualified Liability Partner shall bear the costs incurred by it in connection with the execution of any guaranty to which it is a party. To the extent a Non-Qualified
Liability Partner executes a guaranty, the Operating Partnership shall deliver a copy of such guaranty to the lender under the Guarantied Liability promptly after receiving such copy from the relevant Non-Qualified Liability Partner. 

(c) During the Non-Qualified Liability Period, if the Operating Partnership intends to repay any Non-Qualified Liability with proceeds
generated by its incurrence of other liabilities as provided in Section 2.5(a)(i), the Operating Partnership shall provide at least thirty (30) days’ written notice (a “Section 2.5 Notice”) to each Non-Qualified
Liability Partner that may be affected thereby. The Section 2.5 Notice shall describe which Non-Qualified Liability is being repaid and the nature and amount of the liability, if any, being incurred to repay such Non-Qualified Liability. The
Operating Partnership shall use commercially reasonable efforts to make available to each affected Non-Qualified Liability Partner the opportunity to guaranty any such newly-incurred liability in the same manner as provided in Section 2.5(b)
in an amount equal to the amount of the repaid Non-Qualified Liability that was guarantied by such Non-Qualified Liability Partner immediately prior to the date of the repayment. Any Non-Qualified Liability Partner that desires to execute a guaranty
following the receipt of a Section 2.5 Notice shall provide the Operating Partnership with notice thereof within fifteen (15) days after the date of the Section 2.5 Notice. 

(d) Provided the Operating Partnership satisfies its obligations under Section 2.5(a), (b) and (c) of
this Agreement, it shall have no liability to any Non-Qualified Liability Partner for breach of Section 2.5, whether or not such Non-Qualified Liability Partner accepts its Guaranty Opportunity. For the avoidance of doubt, and notwithstanding
any other provision of this Agreement, the Operating Partnership shall have no liability to any Non-Qualified Liability Partner if the Operating Partnership is unable, despite its commercially reasonable efforts, to provide each Non-Qualified
Liability Partner with the opportunity to guaranty a Non-Qualified Liability. Furthermore, the Operating Partnership makes no representation or warranty to any Non-Qualified Liability Partner concerning the treatment or effect of any guaranty under
Federal, state, local, or foreign tax law, and bears no responsibility for any tax liability of any Non-Qualified Liability Partner or Affiliate thereof that is attributable to a reallocation, by a taxing authority, of debt subject to a guaranty
(other than a reallocation that results from any act or omission taken by the Operating Partnership or one of its Affiliates in violation of this Section 2.5). 

 

 11 

 (e) If the Operating Partnership shall fail to comply with any provision of this Section
2.5, the Operating Partnership shall pay, within thirty (30) days of such failure, a Make Whole Payment to each Non-Qualified Liability Partner who recognizes income or gain as a result of such failure equal to the estimated Make Whole

to the portion of Equity Value represented by such Forward OP Merger Entity Interest (collectively referred to as the “Merger Consideration”) and each holder that receives OP Units in the Mergers shall, upon receipt of such OP Units
and the delivery of a Consent Form or a counterpart signature page to the Operating Partnership Agreement and such other documents and instruments as may be required in the sole discretion of the REIT to effect such holder’s admission as a
limited partner of the Operating Partnership, be admitted as a limited partner of the Operating Partnership in accordance with the MLPA and the Operating Partnership Agreement.

thereof held by a Pre-Formation Participant who is an Accredited Investor shall be distributed in the form of a number of OP Units equal to the applicable portion of such Allocated Share divided by the IPO Price. 

(iii) REIT Shares. The Elected REIT Shares Percentage of the Allocated Share for each Forward OP Merger Entity Interest or
portion thereof held by a Pre-Formation Participant who is an Accredited Investor shall be distributed in the form of a number of REIT Shares equal to the applicable portion of such Allocated Share divided by the IPO Price; provided that, to
the extent such distribution of REIT Shares to the holder of the Forward OP Merger Entity Interests would result in a violation of the restrictions on ownership and transfer set forth in Section 6.3 of the REIT’s charter (the
“Ownership Limits”), such holder shall receive (x) the maximum number of whole REIT Shares that would not result in such a violation of the Ownership Limits, and (y) that number of OP Units equal to the remaining number of

Section 1.06 CANCELLATION AND RETIREMENT OF FORWARD OP MERGER ENTITY INTERESTS. From and after the Effective Time, (i) each
Forward OP Merger Entity Interest converted into the right to receive the Merger Consideration pursuant to Section 1.05(a) shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and

(ii) each Forward OP Merger Entity Interest issued and outstanding that is owned by the REIT, the Operating Partnership or any of their direct or indirect wholly-owned Subsidiaries shall no longer be outstanding and shall automatically be

fractional REIT Shares that a holder of Forward OP Merger Entity Interests would otherwise be entitled to receive as a result of the Mergers and the other Formation Transactions shall be aggregated, and each holder shall receive the number of whole
REIT Shares resulting from such aggregation and, in lieu of any fractional REIT Share resulting from such aggregation, an amount in cash determined by multiplying that fraction of a REIT Share to which such holder would otherwise have been entitled,
by the IPO Price. No interest will be paid or will accrue on any cash paid or payable in lieu of any fractional OP Unit or REIT Share.

Latham & Watkins LLP, 12636 High Bluff Drive, Suite 400 San Diego, California 92130 or such other place as determined by the REIT in its sole discretion. The Closing hereunder and the closing of the IPO shall be deemed concurrent for all

 Section 2.02 PAYMENT OF MERGER CONSIDERATION. 

(a) As soon as reasonably practicable after the Effective Time, the Surviving Entity (or its successor in interest) shall deliver to each
holder of Forward OP Merger Entity Interests, whose Forward OP Merger Entity Interests have been converted into the right to receive the Merger Consideration pursuant to Section 1.05(a) hereof, the Merger Consideration payable to

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR
THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION, UNLESS THE TRANSFEROR DELIVERS TO THE CORPORATION AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION, TO THE EFFECT
THAT THE PROPOSED SALE, TRANSFER OR OTHER DISPOSITION MAY BE EFFECTED WITHOUT REGISTRATION UNDER THE ACT AND UNDER APPLICABLE STATE SECURITIES OR “BLUE SKY” LAWS.

 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON BENEFICIAL AND
CONSTRUCTIVE OWNERSHIP AND TRANSFER FOR THE PURPOSE OF THE CORPORATION’S MAINTENANCE OF ITS STATUS AS A REAL ESTATE INVESTMENT TRUST UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”). SUBJECT TO CERTAIN FURTHER
RESTRICTIONS AND EXCEPT AS EXPRESSLY PROVIDED IN THE CORPORATION’S CHARTER, (I) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF THE CORPORATION’S COMMON STOCK IN EXCESS OF [    ]% (IN VALUE OR
NUMBER OF SHARES) OF THE OUTSTANDING SHARES OF COMMON STOCK OF THE CORPORATION UNLESS SUCH PERSON IS AN EXCEPTED HOLDER (IN WHICH CASE THE EXCEPTED HOLDER LIMIT SHALL BE APPLICABLE); (II) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES
OF CAPITAL STOCK OF THE CORPORATION IN EXCESS OF [    ]% OF THE VALUE OF THE TOTAL OUTSTANDING SHARES OF CAPITAL STOCK OF THE CORPORATION, UNLESS SUCH PERSON IS AN EXCEPTED HOLDER (IN WHICH CASE THE EXCEPTED HOLDER LIMIT
SHALL BE APPLICABLE); (III) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN CAPITAL STOCK THAT WOULD RESULT IN THE CORPORATION BEING “CLOSELY HELD” UNDER SECTION 856(h) OF THE CODE OR OTHERWISE CAUSE THE CORPORATION TO FAIL TO
QUALIFY AS A REIT; AND (IV) NO PERSON MAY TRANSFER SHARES OF CAPITAL STOCK IF SUCH TRANSFER WOULD RESULT IN THE CAPITAL STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS. ANY PERSON WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS OR
ATTEMPTS TO BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK WHICH CAUSES OR WILL CAUSE A PERSON TO BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK IN EXCESS OR IN VIOLATION OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE
CORPORATION. IF ANY OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP SET FORTH IN (I) THROUGH (III) ABOVE ARE VIOLATED, THE SHARES OF CAPITAL STOCK REPRESENTED HEREBY WILL BE AUTOMATICALLY TRANSFERRED TO A TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE
OR MORE CHARITABLE BENEFICIARIES. IN ADDITION, THE CORPORATION MAY TAKE OTHER ACTIONS, INCLUDING REDEEMING SHARES UPON THE TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE AND ABSOLUTE DISCRETION IF THE BOARD OF DIRECTORS

INITIO. ALL UNDERLINED TERMS IN THIS LEGEND HAVE THE MEANINGS DEFINED IN THE CHARTER OF THE CORPORATION, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO
EACH HOLDER OF CAPITAL STOCK OF THE CORPORATION ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE CORPORATION AT ITS PRINCIPAL OFFICE.

 (b) The Surviving Entity (or its successor in interest) shall not be liable to any holder
of a Forward OP Merger Entity Interest for any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. 

(c) So long as some portion of the Merger Consideration with respect to an American Assets Entity is in the form of OP Units, the
parties hereto intend and agree that, for United States federal income tax purposes, the Merger of each such entity shall constitute an “assets-over” partnership merger within the meaning of Treasury Regulations
Section 1.708-1(c)(3)(i), and, as a result, that (i) any payment of cash or REIT Shares for the Forward OP Merger Entity Interests of such holder in such entity shall be treated as a sale of such Forward OP Merger Entity Interests by the
holder and a purchase of such Forward OP Merger Entity Interests by the Operating Partnership for the cash and/or REIT Shares so paid under the terms of this Agreement in accordance with Treasury Regulations Section 1.708-1(c)(4), and
(ii) each such holder of the Forward OP Merger Entity Interests who accepts cash and/or REIT Shares shall explicitly agree and consent (the “Sale Consent”) to such treatment in their Consent Form as a condition to electing such
consideration. To the extent the Operating Partnership acquires any Forward OP Merger Entity Interests as described above, or previously acquired such interest, for United States federal income tax purposes the receipt by the Operating Partnership
of the portion of property attributable to such Forward OP Merger Entity Interests shall be treated as a distribution by a Forward OP Merger Entity in redemption of such Forward OP Merger Entity Interests. Notwithstanding Section 1.05(a)
and any holder’s election as to the form of their Merger Consideration, if any holder (other than a non-accredited investor), fails to execute a Sale Consent prior to the Closing, such holder’s Merger Consideration shall consist solely of
OP Units. Any cash paid as the Merger Consideration to a non-accredited investor for a Forward OP Merger Entity Interest shall be paid only after the receipt of a Sale Consent from such holder. 

Section 2.03 TAX WITHHOLDING. The Operating Partnership and each Forward OP Merger Entity shall be entitled to deduct and withhold
from the consideration payable pursuant to this Agreement to any holder of a Forward OP Merger Entity Interest such amounts required to be deducted and withheld with respect to the making of such payment under the Code or any provision of state,
local or foreign tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Forward OP Merger Entity Interests in respect of which such
deduction and withholding was made. 
 Section 2.04 FURTHER ACTION. If, at any time after the Effective Time, the
Surviving Entity shall determine or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Entity the right,
title or interest in, to or under any of the rights, properties or assets of any Forward OP Merger Entity acquired or to be acquired by the Surviving Entity as a result of, or in connection with, the Mergers or otherwise to carry out this

  

 8 

 
Agreement, the Surviving Entity shall be authorized to execute and deliver, in the name and on behalf of any Forward OP Merger Entity or otherwise, all such deeds, bills of sale, assignments and
assurances and to take and do, in the name and on behalf of any Forward OP Merger Entity or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and
under such rights, properties or assets in the Surviving Entity or otherwise to carry out this Agreement. 
 Section 2.05
TERM OF THE AGREEMENT. This Agreement shall terminate automatically if (i) the initial registration statement of the REIT for the IPO (the “Registration Statement”) has not been filed with the Securities and Exchange Commission
(“SEC”) by March 31, 2011, or (ii) the Mergers shall not have been consummated on or prior to December 31, 2011 (such date is hereinafter referred to as the “Outside Date”). 

Section 2.06 EFFECT OF TERMINATION. In the event of termination of this Agreement for any reason, all obligations on the part of
the Operating Partnership and each Forward OP Merger Entity under this Agreement shall terminate, except that the obligations set forth in Article VIII shall survive; it being understood and agreed, however, for the avoidance of doubt, that
if this Agreement is terminated because one or more of the conditions to a non-breaching party’s obligations under this Agreement are not satisfied by the Outside Date as a result of the other party’s material breach of a covenant,
representation, warranty or other obligation under this Agreement or any other Formation Transaction Documentation, the non-breaching party’s right to pursue all legal remedies with respect to such breach will survive such termination
unimpaired.

Section 8.02 DEFINITIONS. For purposes of this Agreement, the following terms shall have the following meanings. 

(a) “Accredited Investor” has the meaning set forth under Regulation D of the Securities Act. 

(b) “Affiliate” means, with respect to any Person, a Person that, directly or indirectly, through one or more
intermediaries, controls, is controlled by, or is under common control with the specified Person. For the purposes of this definition, “control” (including, with correlative meanings, the terms “controlled by” and “under
common control with”) as used with respect to any Person, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting
securities, by agreement or otherwise. 
 (c) “Allocated Share” means the amount that would be allocated to a
Pre-Formation Participant that is the holder of an interest in an American Assets Entity in accordance with the provisions of the existing Organizational Documents of such entity relating to distributions of distributable net proceeds from sales of
directly or indirectly owned properties or assets, and assuming the sale of the relevant Target Asset or Target Assets that are directly or indirectly owned by such entity for a value equal to such Target Asset’s or Target Assets’
respective Equity Value(s). 
 Notwithstanding the foregoing, the Allocated Share of any Pre-Formation Participant shall reflect the following
adjustments: 
  

	 	1.	Intercompany Debt Adjustment. In calculating Allocated Share, all Intercompany Debt shall be taken into account so that the Allocated Shares of the holders of
direct or indirect Pre-Formation Interests in the obligor of Intercompany Debt collectively are reduced, and the Allocated Shares of the holders of direct or indirect Pre-Formation Interests in the obligee of such Intercompany Debt collectively are
increased, in each case by the amount of such Intercompany Debt (such adjustments being referred to as “Intercompany Debt Adjustments”). 

  

 25 

	 	2.	Entity Specific Debt Adjustment. To the extent that Entity Specific Debt is allocated to a Target Asset, in calculating Allocated Shares of holders of direct or
indirect Pre-Formation Interests in the American Assets Entity or Entities owning such Target Asset, the amount of the decrease in Equity Value of such Target Asset attributable to the allocation of such Entity Specific Debt to such Target Asset
(through the operation of the formula set forth on Schedule III) (in each case, such decrease being the “Decrease”) shall be taken into account so that: 

 

	 	a.	the Allocated Shares of the holders of direct or indirect Pre-Formation Interests in any obligor(s) under such Entity Specific Debt collectively shall be
(i) reduced by the amount equal to the excess of (w) the amount of the Entity Specific Debt owed by such obligor over (x) the amount of the Decrease allocated pro rata to such obligor as a direct or indirect owner of the Target Asset;
or (ii) increased by the amount equal to the excess of (y) the amount of the Decrease allocated pro rata to such obligor as a direct or indirect owner of the Target Asset over (z) the amount of the Entity Specific Debt owed by such
obligor; and 

  

	 	b.	the Allocated Shares of the holders of direct or indirect Pre-Formation Interests in American Assets Entities owning such Target Asset that are not obligors under such
Entity Specific Debt collectively shall be increased by the amount equal to the amount of the Decrease allocated pro rata to such holders as direct or indirect owner of the Target Asset; 

with the net effect under the foregoing clauses (a)(i), (a)(ii) and (b) being that the adverse economic impact of the Decrease shall
be borne equitably by the holders of direct or indirect Pre-Formation Interests in the actual obligor(s) under such Entity Specific Debt and not by any other holder of direct or indirect Pre-Formation Interests in the American Assets Entities owning
such Target Asset. 
 Illustrative examples of the application of the foregoing Allocated Share adjustments using hypothetical numbers are
included as Example 3 and Example 4 in Appendix A to Schedule III.

otherwise been received by such holder of direct or indirect equity interests pursuant to this Agreement, (iii) the restructuring of the Merger as either (x) a merger of the Forward OP Merger Entity with and into either the REIT or a wholly owned
subsidiary of the REIT or the Operating Partnership or (y) a merger of a wholly owned subsidiary of either the REIT or the Operating Partnership with and into the Forward OP Merger Entity, in each case in exchange for the amount of cash and the
number of OP Units and/or REIT Shares that were to be issued pursuant to this Agreement, or (iv) any other transaction pursuant to which the REIT, the Operating Partnership or any of their Subsidiaries acquire the assets held by a Forward OP Merger
Entity or each holder of direct or indirect equity interests in such Forward OP Merger Entity in a transaction pursuant to which each holder of direct or indirect interests in such Forward OP Merger Entity receives the amount of cash, the
number of OP Units and/or the number of REIT Shares that were to be received by such holder pursuant to this Agreement (or a portion thereof equal in value to the value of the portion of such assets acquired by the REIT, the Operating Partnership or
any of their Subsidiaries pursuant to such Alternate Transaction). 
  

 26 

 (e) “American Assets Entity” means a Forward OP Merger Entity, Forward
REIT Merger Entity, OP Sub Reverse Merger Entity, OP Sub Forward Merger Entity, REIT Sub Forward Merger Entity, Contributed Entity or OP Sub Contributed Entity, as applicable. As used herein, “American Assets Entities” refer to each

party’s rights under this Agreement. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitral tribunal shall have full authority to grant provisional remedies and to direct the parties
to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any party to respect the arbitral tribunal’s orders to that effect.

Reimbursement Agreements 
  

	 	1.	Letter Agreement by and among American Assets, Inc. and the Property Entities (as defined therein) dated May 17, 2010 

 Schedule III 

Calculation of Equity Value 

For purposes of all Formation Transaction Documentation, “Equity Value” of any Target Asset directly or indirectly owned
by the American Assets Entity subject to such agreement shall be calculated pursuant to the formula set forth below. Capitalized terms used in this Schedule III shall have the meanings set forth below and capitalized terms used herein without
definition shall have the meanings assigned to such terms in the Agreement. 
 EV = EP × [TFTV-TPA]+AA; 

where: 
 EV = Equity Value; 

EP = Equity Percentage; 
 TFTV= Total Formation
Transaction Value; 
 TPA = Total Portfolio Adjustment; and 

AA = Asset Adjustment; 
 provided, however,
that if the resulting Equity Value for a Target Asset is a negative amount (a “Net Deficit”), then the REIT shall exercise one of the following options, as determined by the REIT in its sole and absolute discretion:
(i) select the Target Asset as an Eliminated Asset or (ii) if one or more entities that are subject to the Formation Transaction Documentation that are the direct or indirect owners of such Target Asset would otherwise possess Excluded
Assets the value of which in the aggregate would equal or exceed the amount of such Net Deficit, increase the Target Net Working Capital with respect to such entity or entities by the absolute value of such Net Deficit; and provided further
that if the REIT shall have exercised option (ii) with respect to any Target Asset, the Equity Value with respect to such Target Asset shall be deemed to be equal to zero; 

provided further, that if the Equity Value for ICW Valencia/Valencia Corporate Center as calculated above would result in the holders of direct or
indirect Pre-Formation Interests in ICW Valencia, L.P. having an amount of Allocated Shares, prior to the application of the Intercompany Debt Adjustments, that is less than the value of the Intercompany Debt owed by ICW Valencia, L.P. to ICW Plaza,
L.P. (such shortfall being referred to as the “Intercompany Debt Shortfall”), then (i) Western Insurance Holdings, Inc. shall issue a promissory note with a term of three years to ICW Valencia, L.P. which shall be treated as an
Asset Adjustment with respect to ICW Valencia/Valencia Corporate Center and such promissory note (the “WIH Note”) shall have such face amount as shall be necessary to increase the Equity Value of ICW Valencia/Valencia Corporate
Center such that the Allocated Shares of holders of direct or indirect Pre-Formation Interests in ICW Valencia, L.P. shall increase by an amount, prior to the application of the Intercompany Debt Adjustments, equal to the Intercompany Debt Shortfall
and (ii) the Equity Value for ICW Valencia/Valencia Corporate Center shall be recalculated to give effect to the Asset Adjustment attributable to the issuance of the WIH Note. 

 Attached as Appendix A to this Schedule III are illustrative calculations of Equity
Value for a hypothetical portfolio of Target Assets. 
 “Actual Balance” shall mean: (i) with respect to each Existing
Loan to be assumed in connection with the IPO, the unpaid principal amount of and past due unpaid interest on such Existing Loan as of the IPO Closing Date and immediately prior to any such assumption and all assumption fees and any related expenses
with respect to such Existing Loan; and (ii) with respect to each Existing Loan to be prepaid, repaid or refinanced in connection with the IPO, the unpaid principal amount of and past due unpaid interest on such Existing Loan as of the IPO
Closing Date and immediately prior to any such prepayment, repayment or refinancing and any related prepayment penalties and any related expenses; provided, however, that in the event a Target Asset is not included in the Formation
Transactions pursuant to a merger (or contribution of all direct or indirect Pre-Formation Interests in such Target Asset) but a portion of the direct or indirect Pre-Formation Interests in such Target Asset is otherwise contributed to the Operating
Partnership or a subsidiary of the Operating Partnership, then the Actual Balance for such Target Asset shall be proportionately adjusted to take into account the portion of the direct or indirect Pre-Formation Interests in such Target Asset that
will not be so contributed. With respect to each Existing Loan to be assumed, prepaid, repaid or refinanced in connection with the Formation Transactions, the Actual Balance as of the Closing Date shall be determined by the REIT within forty five
(45) days prior to the date of the preliminary prospectus used in the IPO roadshow based on its good faith estimate of what such amounts will be as of the IPO Closing Date. 

“Asset Adjustment” shall mean with respect to each Target Asset and any Existing Loan relating to such Target Asset, an amount equal to
the Base Balance minus the Actual Balance (expressed as a positive or negative number, as applicable) with respect to all Existing Loans relating to such Target Asset, and in the case of ICW Valencia/Valencia Corporate Center, the face value of the
WIH Note shall be deemed to reduce the Actual Balance of the Existing Loan relating to ICW Valencia/Valencia Corporate Center. 
 “Base
Balance” shall mean with respect to each Existing Loan, the principal amount of such Existing Loan set forth on Appendix C to this Schedule III; provided, however, that in the event a Target Asset is not included
in the Formation Transactions pursuant to a merger (or contribution of all direct or indirect Pre-Formation Interests in such Target Asset) but a portion of the direct or indirect Pre-Formation Interests in such Target Asset is otherwise contributed
to the Operating Partnership or a subsidiary of the Operating Partnership, then the Base Balance for such Target Asset shall be proportionately adjusted to take into account the portion of the direct or indirect Pre-Formation Interests in such
Target Asset that will not be so contributed. 
 “Eliminated Asset” shall mean any Target Asset subject to the Formation
Transaction Documentation that is excluded pursuant to the terms of the Formation Transaction Documentation from the Formation Transactions. 

“Equity Percentage” shall mean with respect to each Target Asset, the percentage (expressed as a decimal) set forth opposite the name of
such Target Asset on Appendix B to this Schedule III (which percentage is based on the Fairness Opinion of Duff & Phelps, LLC and represents such 

 
Target Asset’s percentage of the net asset values of the Target Assets (other than the Management Company) and the net equity value of the Management Company, taken as a whole); provided,
however, that in the event a Target Asset is selected as or otherwise becomes for any reason an Eliminated Asset, then: (i) the Equity Percentage for each remaining Target Asset shall be recalculated as a fraction, the numerator of which is
the original Equity Percentage for such remaining Target Asset and the denominator of which is (A) 100 minus (B) the original Equity Percentage of the Eliminated Asset; and (ii) the Equity Percentage of the Eliminated Asset shall be
zero; and provided, further, that in the event a Target Asset is not included in the Formation Transactions pursuant to a merger (or contribution of all direct or indirect Pre-Formation Interests in such Target Asset) but a portion of
the direct or indirect Pre-Formation Interests in such Target Asset is otherwise contributed to the Operating Partnership or a subsidiary of the Operating Partnership, then, after giving effect to any Eliminated Assets pursuant to the preceding
proviso, the Equity Percentage for such Target Asset and for each other remaining Target Asset subject directly or indirectly to the Formation Transaction Documentation shall be proportionately adjusted to take into account the portion of the direct
or indirect Pre-Formation Interests in such Target Asset that will not be so contributed. 
 “Excluded Assets” has the meaning
set forth in Section 5.03 to the Agreement. 
 “Existing Loan” shall mean (i) each mortgage or mezzanine loan
secured by a Target Asset listed on Appendix C to this Schedule III and (ii) all unsecured indebtedness of an American Assets Entity or of an entity in which an American Assets Entity has a direct or indirect interest that
will be assumed, prepaid, repaid or refinanced in connection with the IPO and that is set forth on Appendix D to this Schedule III (all indebtedness falling within the scope of this clause (ii) shall be referred to as
“Entity Specific Debt”); for the avoidance of doubt, no Intercompany Debt shall constitute an Existing Loan (in order to avoid double counting, as Intercompany Debt is adjusted for through the definition of “Allocated
Share”). Existing Entity Specific Debt will be deemed to relate to the Target Asset(s) and, if to multiple Target Assets, in the proportions set forth opposite the name of such Entity Specific Debt on Appendix D to this
Schedule III, and all such Entity Specific Debt will be deemed to have a Base Balance of zero (because “Equity Percentage” as determined by Duff & Phelps, LLC was determined at the property level and did not take into
account Entity Specific Debt, Entity Specific Debt is deemed to be zero in order to cause a readjustment of “Equity Value” of all Target Assets after taking into account such Entity Specific Debt). 

“Target Asset” shall mean each property set forth on Appendix B to this Schedule III and the property management business
of American Assets, Inc. (the “Management Company”). 
 “Target Net Working Capital” has the meaning set forth
in Schedule 5.03 to the Agreement. 
 “Total Portfolio Adjustment” shall mean the sum (which may be a positive or
negative number) of all Asset Adjustments for every Target Asset, excluding Eliminated Assets. 
 “Total Formation Transaction
Value” shall mean the aggregate dollar value of (i) the cash, (ii) the REIT Shares and (iii) the OP Units that are issued or issuable to all Pre-Formation Participants in the Formation Transactions as set forth in the
Prospectus. Total Formation Transaction Value will be determined valuing REIT Shares and OP Units at a value per REIT Share or OP Unit equal to the IPO Price.
