 EXHIBIT A 
 TO RESTRICTED STOCK AWARD GRANT NOTICE 
 RESTRICTED STOCK AWARD AGREEMENT

 Pursuant to the Restricted Stock Award Grant Notice (“Grant Notice”) to which this Restricted
Stock Award Agreement (this “Agreement”) is attached, American Assets Trust, Inc., a Maryland corporation (the “Company”), has granted to Participant the right to purchase the number of shares of
Restricted Stock under the Company’s 2011 Equity Incentive Award Plan (the “Plan”) indicated in the Grant Notice. The Shares are subject to the terms and conditions of the Plan which are incorporated herein by reference.
Capitalized terms not specifically defined herein shall have the meanings specified in the Plan and the Grant Notice. 

ARTICLE I 

ISSUANCE OF SHARES 
 1.1 Issuance of Shares. Pursuant to the Plan and subject to the terms and conditions of this Agreement, effective on the Grant Date, the Company irrevocably grants to Participant the number of
shares of Stock set forth in the Grant Notice (the “Shares”), in consideration of Participant’s employment with or service to the Company, the Partnership or one of their Subsidiaries on or before the Grant Date, for
which the Administrator has determined Participant has not been fully compensated, and the Administrator has determined that the benefit received by the Company as a result of such employment or service has a value that exceeds the aggregate par
value of the Shares, which Shares, when issued in accordance with the terms hereof, shall be fully paid and nonassessable. 

1.2 Issuance Mechanics. On the Grant Date, the Company shall issue the Shares to Participant and shall (a) cause a stock
certificate or certificates representing the Shares to be registered in the name of Participant, or (b) cause such Shares to be held in book entry form. If a stock certificate is issued, it shall be delivered to and held in custody by the
Company and shall bear the restrictive legends required by Section 4.1 below. If the Shares are held in book entry form, then such entry will reflect that the Shares are subject to the restrictions of this Agreement. Participant’s
execution of a stock assignment in the form attached as Exhibit B to the Grant Notice (the “Stock Assignment”) shall be a condition to the issuance of the Shares. 

ARTICLE II 

FORFEITURE AND TRANSFER RESTRICTIONS 
 2.1 Forfeiture Restriction. Subject to the provisions of Section 2.2 below, in the event of Participant’s cessation of Service for any reason, including as a result of Participant’s
death or Disability, all of the Unreleased Shares (as defined below) shall thereupon be forfeited immediately and without any further action by the Company (the “Forfeiture Restriction”). Upon the occurrence of such a
forfeiture, the Company shall become the legal and beneficial owner of the Unreleased Shares and all rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of
Unreleased Shares being forfeited by Participant. The Unreleased Shares and Participant’s executed stock assignment in the form attached as Exhibit B to the Grant Notice shall be held by the Company in accordance with Section 2.4
until the Shares are forfeited as provided in this 

  
 A-1









 
Section 2.1, until such Unreleased Shares are fully released from the Forfeiture Restriction, or until such time as this Agreement no longer is in effect. Participant hereby authorizes and
directs the Secretary of the Company, or such other person designated by the Committee, to transfer the Unreleased Shares which have been forfeited pursuant to this Section 2.1 from Participant to the Company. 

2.2 Release of Shares from Forfeiture Restriction. The Shares shall be released from the Forfeiture Restriction in accordance with
the vesting schedule set forth in the Grant Notice. Any of the Shares which, from time to time, have not yet been released from the Forfeiture Restriction are referred to herein as “Unreleased Shares.” As soon as
administratively practicable following the release of any Shares from the Forfeiture Restriction, the Company shall, as applicable, either deliver to Participant the certificate or certificates representing such Shares in the Company’s
possession belonging to Participant, or, if the Shares are held in book entry form, then the Company shall remove the notations on the book form. Participant (or the beneficiary or personal representative of Participant in the event of
Participant’s death or incapacity, as the case may be) shall deliver to the Company any representations or other documents or assurances as the Company or its representatives deem necessary or advisable in connection with any such delivery.

 2.3 Transfer Restriction. No Unreleased Shares or any interest or right therein or part thereof shall be liable for
the debts, contracts or engagements of the Participant or his successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect. 

2.4 Escrow. The Unreleased Shares and Participant’s executed Stock Assignment shall be held by the Company until the Shares
are forfeited as provided in Section 2.1, until such Unreleased Shares are fully released from the Forfeiture Restriction, or until such time as this Agreement no longer is in effect. In such event, Participant shall not retain physical custody
of any certificates representing Unreleased Shares issued to Participant. Participant, by acceptance of this Award, shall be deemed to appoint, and does so appoint, the Company and each of its authorized representatives as Participant’s
attorney(s)-in-fact to effect any transfer of forfeited Unreleased Shares to the Company as may be required pursuant to the Plan or this Agreement, and to execute such representations or other documents or assurances as the Company or such
representatives deem necessary or advisable in connection with any such transfer. The Company, or its designee, shall not be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and
in the exercise of its judgment. 
 2.5 Rights as Stockholder. Except as otherwise provided herein, upon issuance of the
Shares by the Company, Participant shall have all the rights of a stockholder with respect to said Shares, subject to the restrictions herein, including the right to vote the Shares and to receive all dividends or other distributions paid or made
with respect to the Shares. 
 2.6 Ownership Limit and REIT Status. The Forfeiture Restriction on the Shares shall not
lapse if the lapsing of such restrictions would likely result in any of the following: 
 (a) a violation of the restrictions or
limitations on ownership provided for from time to time under the terms of the organizational documents of the Company; or 

(b) income to the Company that could impair the Company’s status as a real estate investment trust, within the meaning of
Section 856 through 860 of the Code. 

  
 A-2









 ARTICLE III 
 TAXATION REPRESENTATIONS 
 Participant represents to the Company the
following: 
 (a) Participant has reviewed with his or her own tax advisors the federal, state, local and foreign tax
consequences of this investment and the transactions contemplated by this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Participant understands that
Participant (and not the Company) shall be responsible for his or her own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 

(b) Notwithstanding anything to the contrary in this Agreement, the Company shall be entitled to require payment (which payment may be
made in cash, by deduction from other compensation payable to Participant or in any form of consideration permitted by the Plan) of any sums required by federal, state or local tax law to be withheld with respect to the issuance, lapsing of
restrictions on or sale of the Shares. The Company shall not be obligated to deliver any stock certificate representing vested Shares to Participant or Participant’s legal representative, or, if the Shares are held in book entry form, to remove
the notations on the book form, unless and until Participant or Participant’s legal representative shall have paid or otherwise satisfied in full the amount of all federal, state and local taxes applicable to the taxable income of Participant
resulting from the issuance, lapsing of restrictions on or sale of the Shares. 
 (c) Participant covenants that he or she will
not make an election under Section 83(b) of the Code with respect to the receipt of any of the Shares without the consent of the Administrator, which the Administrator may grant or withhold in its sole discretion. 

ARTICLE IV 

RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS 
 4.1 Legends. The certificate or certificates representing the Shares, if any, shall bear the following legend (as well as any legends required by the Company’s charter and applicable state and
federal corporate and securities laws): 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO FORFEITURE IN FAVOR OF THE
COMPANY AND MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF A RESTRICTED STOCK AWARD AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

4.2 Refusal to Transfer; Stop-Transfer Notices. The Company shall not be required (a) to transfer on its books any Shares
that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (b) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such
Shares shall have been so transferred. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that,
if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

  
 A-3









 4.3 Removal of Legend. After such time as the Forfeiture Restriction shall have
lapsed with respect to the Shares, and upon Participant’s request, a new certificate or certificates representing such Shares shall be issued without the legend referred to in Section 4.1, and delivered to Participant. If the Shares are
held in book entry form, the Company shall cause any restrictions noted on the book form to be removed. 
 ARTICLE V
