Confidential Separation Agreement and Release of Claims by and between Kilroy Realty Corporation, Kilroy Realty, L.P. and Stephen A. Rosetta effective as of August 26, 2019

This Confidential Separation Agreement and Release of Claims (“Agreement”) is entered into by and between, on the one hand, Stephen A. Rosetta (“Mr. Rosetta”) and, on the other hand, Kilroy Realty Corporation, a Maryland corporation, and Kilroy Realty, L.P., a Delaware limited partnership (collectively, “KRC”). KRC and Mr. Rosetta may be referred to herein jointly as “the parties” or individually as “the party.”

WHEREAS, KRC has employed Mr. Rosetta as Executive Vice President, Chief Investment Officer;

WHEREAS, the parties have agreed that Mr. Rosetta will separate from his employment with KRC on August 28, 2019 (the “Separation Date”);

WHEREAS, KRC and Mr. Rosetta desire to resolve any and all matters and disputes between them as of the Effective Date of the Agreement, as defined below in Section 17, in an amicable manner, and to set out the terms for payment of additional consideration to Mr. Rosetta to secure the full and final release of all claims set forth herein; and

WHEREAS, KRC and Mr. Rosetta understand and acknowledge that each of them is waiving legal rights or claims by signing the Agreement, and that each of them voluntarily enters into the Agreement with a complete understanding of its terms and with the intent to be bound thereby.

NOW, THEREFORE, in consideration of the mutual covenants and promises contained herein, and for other good and valuable consideration, receipt of which is hereby acknowledged, KRC and Mr. Rosetta agree as follows:

1.1    Through the Separation Date, Mr. Rosetta acknowledges and agrees that he has continuing obligations as Executive Vice President, Chief Investment Officer, to fulfill his duties and responsibilities, including but not limited to cooperating with KRC management and supporting an orderly transition of all projects under his management or direction and any other matters concerning existing or potential projects (acquisitions or dispositions), as well as tenants, vendors, suppliers, partners, joint ventures, brokers, agents, buyers, or anyone else with whom KRC does business. KRC shall have the right to accelerate Mr. Rosetta’s separation from employment for any reason prior to the Separation Date provided that KRC shall pay Mr. Rosetta the balance of any salary, vacation, holiday, and floating holiday pay as if earned.

1.2    On the Separation Date Mr. Rosetta shall cease to be an employee of KRC. For the avoidance of doubt, the parties intend that the Separation Date shall constitute the date on which Mr. Rosetta shall cease to provide any and all services to KRC and its affiliates as an employee or otherwise (including without limitation services on any committee, boards or as an officer). Mr.

Rosetta agrees that the Separation Date shall constitute the date of Mr. Rosetta’s “separation from service” from KRC (within the meaning of Internal Revenue Code Section 409A (“Section 409A”) and the guidance promulgated thereunder).

1.3    Mr. Rosetta acknowledges, agrees and represents that for a period of one year after the Separation Date he will use commercially reasonable efforts to assist KRC with respect to specific projects he worked on during his employment at KRC which KRC currently owns or is actively pursuing. Nothing stated herein shall in any way amend or diminish Mr. Rosetta’s obligations under the Confidentiality Agreement, as defined below, or pursuant to the confidentiality provisions of the Agreement, particularly but without limitation Section 10.

1.4    The parties acknowledge and agree that Mr. Rosetta executed a “Non-Competition, Non-Solicitation and Non-Disclosure Agreement” dated June 19, 2017 (the “Confidentiality Agreement”), which is enforceable to the fullest extent provided by law. Mr. Rosetta further acknowledges and agrees that he has a continuing obligation after the Separation Date not to disclose, transmit, use or otherwise appropriate KRC’s Confidential Information, as defined below in Section 10; and further acknowledges and agrees that his post-employment obligations include in particular but without limitation (i) his obligations not to solicit or raid any current employees, customers, vendors, suppliers or joint venturers to terminate their employment or to cease doing business with KRC using Confidential Information protected by Section 10 of the Agreement; (ii) his obligations not to disclose or to interfere with a market expansion, acquisition or development (including joint venture) opportunity for KRC using Confidential Information protected by Section 10 of the Agreement; (iii) without limitation, but particularly, his obligations under the non-disparagement and confidentiality obligations set forth, respectively, in Sections 9 and 10 of the Agreement; and (iv) his obligations and undertakings set forth in Section 2.

1.5    Except as otherwise expressly authorized by KRC in writing, on and after the Separation Date, Mr. Rosetta shall not represent or act, directly or indirectly, for or on behalf of, or otherwise as an agent of, KRC or any one of the KRC Released Parties, as defined below in Section 4.1.

1.6    On the Separation Date KRC shall pay to Mr. Rosetta all unpaid salary and accrued but unused vacation and any floating holiday pay which would have been earned through the Separation Date, at Mr. Rosetta’s then current regular base salary rate, less applicable state and federal tax withholdings. KRC shall also reimburse Mr. Rosetta for all approved reasonable and necessarily incurred business expenses and disbursements that have not otherwise been reimbursed, upon receipt of the required documentation. No expenses shall be incurred by Mr. Rosetta on or after the Separation Date, for or on behalf of KRC without express written advance authorization.

1.7    KRC will not dispute a claim for unemployment benefits should one be filed by Mr. Rosetta, though Mr. Rosetta acknowledges that it is the California Employment Development Department and not KRC which determines eligibility for such benefits.

1.8    KRC will maintain Mr. Rosetta’s personnel file and any financial information that Mr. Rosetta provided to KRC in a confidential manner. Mr. Rosetta's personnel and payroll

records shall reflect that he separated from employment due to mutual agreement. Mr. Rosetta shall direct prospective employers to KRC’s Human Resources Department which will respond to any request for a reference by providing dates of employment and last held position, unless written authorization is provided at the time by Mr. Rosetta to disclose his most recent regular base salary.

1.9    Mr. Rosetta understands that KRC-provided group health benefits will cease as of September 1, 2019, at which time he and any other participants previously enrolled through him will become eligible for continued medical insurance benefits through COBRA. Should Mr. Rosetta elect in a timely manner to continue COBRA coverage on and after September 1, 2019 for himself or any other previously enrolled participants, COBRA premium payments shall be made directly by Mr. Rosetta to the attention of “Benefits Administrator”, Kilroy Realty Corporation, 12200 W. Olympic Blvd., Suite 200, Los Angeles, CA 90064. Accordingly, commencing on and after September 1, 2019, KRC shall have no obligation to pay for or to reimburse the cost of medical insurance benefits for Mr. Rosetta or any other previously enrolled participants.

1.10    The parties acknowledge and agree that pursuant to the July 19, 2017 Cash Award Terms Agreement (the “July 19 Agreement”), an account was established in Mr. Rosetta’s name under KRC’s 2007 Deferred Compensation Plan (the “Plan”), and Mr. Rosetta was credited with Two Million Dollars ($2,000,000.00) (the “Cash Award”), which was subject to a risk of forfeiture under the vesting provisions provided in the July 19 Agreement.

1.10.1    Pursuant to the July 19 Agreement, the sum of One Million Dollars ($1,000,000.00) of the Cash Award has vested (the “Vested Cash Award”). On November 12, 2017 and May 26, 2018, Mr. Rosetta elected to defer payment of the portions of the Cash Award that vested on July 19, 2018 and July 19, 2019, respectively. In accordance with Section 6.1(a)(iii) of the Plan, the deferred Vested Cash Award shall be distributed in a lump sum payment as soon as practicable after Mr. Rosetta’s Specified Employee Payment Date (as such term is defined in the Plan) and net of applicable tax withholding obligations.

1.10.2    Mr. Rosetta further acknowledges and agrees that the remainder of the Cash Award in the sum of One Million Dollars ($1,000,000.00) has not vested in accordance with the terms of the July 19 Agreement (the “Unvested Cash Award”). In accordance with the terms of the July 19 Agreement, the entire Unvested Cash Award shall be forfeited as of the Separation Date and Mr. Rosetta shall have no remaining rights to any portion of the Unvested Cash Award as of the Separation Date.

1.11    Mr. Rosetta was previously awarded restricted stock units (“RSUs”) by KRC pursuant to certain Restricted Stock Unit Agreements (each, an “RSU Agreement”). As of the Separation Date, Mr. Rosetta will have a total of approximately 1,874.348727 RSUs that are vested, time-based and deferred (the “Vested RSUs”) that are held in an account KRC established at Solium, Inc. in Mr. Rosetta’s name (the “Solium Account”). The Vested RSUs consist of the following: 1,874.348727 shares (2018 LTI Award (Time) – EVP). Subject to the terms in the applicable RSU Agreement, the Vested RSUs shall be distributed to Mr. Rosetta in a single distribution of KRC common stock as soon as practicable after the date that is six (6) months and one (1) day following the Separation Date (the “Delayed Payment Date”), after taking into account the notional earnings or losses occurring prior to the Delayed Payment Date and net of applicable

tax withholding obligations, subject to delay for administrative convenience set forth in the applicable RSU Agreement. To the extent that any additional RSUs are credited as dividend equivalents with respect to the RSUs prior to the date of payment, such additional RSUs shall be paid in shares of KRC common stock, or the cash equivalent, on or within fifteen (15) days after the Delayed Payment Date, subject to delay for administrative convenience set forth in the applicable RSU Agreement. In the event of any inconsistency or ambiguity between this Agreement and the applicable RSU Agreement as to the payment of any RSU, the applicable RSU Agreement controls. There can be no guarantee or promise as to the value of a share of KRC common stock or RSUs on any future date. The unvested, time-based and deferred RSUs (the “Unvested RSUs”) totaling approximately 64,787.92466 unvested RSUs, that are held in an account KRC established at Solium, Inc. in Mr. Rosetta’s name (the “Solium Account) shall be forfeited as of the Separation Date and Mr. Rosetta shall have no remaining rights to any portion of the Unvested RSUs as of the Separation Date.

1.12    Mr. Rosetta acknowledges and agrees that (a) KRC has established the Solium Account, (b) Mr. Rosetta will transfer all shares of his KRC common stock and cash amounts in the Solium Account to his personal brokerage and/or bank account as soon as possible, but by no later than March 1, 2020 and (c) KRC will remove Mr. Rosetta’s access to the Solium Account immediately following such date. Furthermore, in accordance with KRC’s Insider Trading Policy, Mr. Rosetta hereby acknowledges and agrees not to buy, sell or otherwise trade in any KRC securities while in possession of any material non-public information about KRC.

1.13    Except as expressly provided for in this Section 1 (or in Section 2 provided conditions set forth therein are satisfied), Mr. Rosetta acknowledges and agrees that all obligations of KRC to pay base salary, benefits, discretionary cash bonus for 2019 (which may be awarded in 2020), vacation and floating holiday pay, deferred cash or equity or other awards, RSUs, deferred compensation, Cash Award, auto allowance, separation pay, incentive pay, 401(k) contributions including the KRC matching contribution, or any other employee benefits, or any other compensation or remuneration of any kind in connection with Mr. Rosetta’s employment with KRC, or in connection with his separation from employment, shall cease as of the Separation Date, and that no compensation or other remuneration, or other payments of any kind, shall be due and owing to him from KRC, or from any of the KRC Released Parties, as defined in Section 4.1, for the period of time that Mr. Rosetta as an employee of KRC, or in connection with his separation from employment and the termination thereof. Nothing stated herein shall amend any ERISA benefit plans in which Mr. Rosetta is a participant. Any other or additional forms of payment by KRC to Mr. Rosetta, including the amounts set forth in Section 2, below (“Additional Consideration”) shall be made only as consideration for the releases, covenants, promises and obligations given and made by Mr. Rosetta in this Agreement, provided that Mr. Rosetta shall not have revoked this Agreement in accordance with Section 6, below. Mr. Rosetta agrees that he has no rights in or with respect to any equity or equity-based awards granted by KRC or any of its affiliates except as specifically referenced in Sections 1.11, 1.12 and 1.13, above.

1.14    On the Separation Date Mr. Rosetta shall coordinate with Human Resources for the return of the following: (i) except as provided below in Section 1.14.1, all KRC property including all tangible or intangible property, such as equipment (including the company satellite phone), software, information, office, parking and/or elevator access keys, books and data, that he was

provided during his employment; (ii) Confidential Information, as that term is defined in the Confidentiality Agreement and below in Section 10; and (iii) a complete list of all computer and website log-in passwords that he used for KRC work purposes (each and collectively, “KRC Property”).

Additionally, as a limited and narrow exception hereto, Mr. Rosetta may retain any personnel or payroll records for himself to which he is legally entitled.

1.14.1    As a limited and narrow exception to Section 1.14, Mr. Rosetta may retain the iPhone (with contact information, e.g., name, telephone number and email address) and iPad provided to him by KRC on condition that prior to the Separation Date, KRC Information Technology (IT) shall be provided access to each of these devices to remove any KRC-related information or material, and further provided that Mr. Rosetta shall have signed and not revoked this Agreement as provided for in Section 6, and shall otherwise comply with all confidentiality obligations. Mr. Rosetta shall also coordinate with Human Resources and the IT Department in identifying any personal data or contact information for his retention.

1.14.2    KRC will also release Mr. Rosetta’s cell phone number so he will be allowed to retain it and his contacts from his Microsoft Outlook file, provided that any KRC Confidential Information contained in his contacts shall first be wiped clean from the cell phone by KRC IT and/or transferred to KRC.

1.15    Mr. Rosetta represents and warrants that he is not entitled to payment of any consideration, including by way of commissions, bonus or other form of remuneration, pursuant to that “Consulting Agreement” by and between KRC and Cushman & Wakefield of San Diego, Inc. (“C&W”) effective as of November 1, 2016 (the “Consulting Agreement”).

The parties acknowledge and agree that any arbitrator shall have no power or authority to alter this provision should Mr. Rosetta breach the Agreement, and that this remedy shall be in addition to any remedy to which KRC is entitled as a prevailing party.

2.2    Other than the payments set forth expressly herein in Sections 1 and 2, Mr. Rosetta acknowledges and agrees that no other payments of any kind or in any amount shall be due and owing, or are due and owing, to him from KRC, or from any of the KRC Released Parties, as Additional Consideration for the releases set forth herein.

KRC and Mr. Rosetta expressly acknowledge and agree that this Agreement represents a settlement of disputed rights and claims and that, by entering into the Agreement, neither KRC nor

any one of the KRC Released Parties nor Mr. Rosetta admits or acknowledges the existence of any liability or wrongdoing, all such liability being specifically and expressly denied.

9.1    Mr. Rosetta acknowledges and agrees that he has held, and will continue to hold through the Separation Date a prominent leadership position of trust and confidence with KRC as an officer and fiduciary of KRC. Mr. Rosetta specially acknowledges and agrees that his obligation of non-disparagement is a material term of the Agreement and condition for the payment of Additional Consideration under the terms set forth herein. Accordingly, before or after the Separation Date, neither Mr. Rosetta nor KRC (through its authorized officers) shall take any action, directly, indirectly or through third parties (without limitation including their respective counsel), to disparage or defame the other in the community-at-large or in the media, including the Internet, Blogs, Social Media (such as Facebook, LinkedIn, Glassdoor and Twitter), or other Internet Access forum.

9.2    KRC shall issue the statement regarding Mr. Rosetta’s departure from KRC which is attached hereto as Exhibit “A” and is incorporated herein by this reference as though set forth in full. The press release shall be issued by KRC by no later than four (4) business days after the execution of the Agreement by both parties. Until the press release is actually issued, Mr. Rosetta shall make no further statements regarding his departure from KRC, and once the press release is issued, he shall make statements only as provided in Section 10.4. KRC shall have sole discretion to prepare and file any required 8-K or 10-Q report.

10.1    The parties acknowledge and agree that the Confidentiality Agreement, which is fully executed by and between them, remains in full force and to the fullest extent provided by law. Mr. Rosetta acknowledges and agrees that his agreement to undertake and abide by the continuing obligations of the Confidentiality Agreement was a material term of his employment and that such obligations continue to be material to KRC. Any restrictive covenants applicable to Mr. Rosetta pursuant to the Agreement are in addition to, not in lieu of, the restrictive covenants set forth in the Confidentiality Agreement. Mr. Rosetta represents and warrants that he has complied with his obligations under the Confidentiality Agreement, that the Confidentiality Agreement remains in full force and effect, and that he will not breach the Confidentiality Agreement.

10.2    As used throughout the Agreement, the term “Confidential Information” includes that which is defined by the Confidentiality Agreement, and as well for the avoidance of doubt,

information, writings, communications or materials of any nature and in any form (including but not limited to that which is electronically or digitally created, generated, transmitted or stored; email and any attachments thereto; hard copies and drafts; pictures and video; or text messages and communications on any cellular device), which have not entered the public domain (except for that Confidential Information which may have entered the public domain by virtue of a breach of the provisions herein or through any wrongdoing by any other person) about the following: confidential, privileged, proprietary, and/or trade secret information, including but not limited to all or any part of any KRC customer or tenant lists and related customer or tenant information (including but not limited to existing and prospective customer or tenant contact information and customer or tenant needs, preferences, sales and similar data); information about KRC’s current and prospective tenants and the premises or properties they have leased or occupy, or may lease or occupy; leases and lessees; property assets; acquisition targets and/or buyers; currently identified or prospective strategic markets (including but not limited to Class A office, mixed use and Life Science); sales, advertising or marketing; development plan(s) or methods; strategic plans whether or not in development or finalized; broker contracts; customary course of KRC’s dealings with brokers, computer system and internet configurations; financial data including without limitation pricing, bid information; employee confidential personnel information, audit processes and information; insurance; designs, patterns, processes, procedures, formulas, blueprints, templates and product development or testing information; company-generated computer software and source and object codes; compilation of information; improvements or inventions; business plans (including prospective and existing acquisition, disposition or development plans); joint ventures or potential joint ventures currently known to KRC, communications with company counsel in connection with KRC legal matters (whether or not a civil action has been commenced); public relations; negotiation, litigation and/or settlement strategies of KRC in connection with any matter whatsoever; financial matters and record-keeping; banking relationships; methods, know-how, research techniques; patents and patent applications; inventions and improvements, whether patentable or not; KRC’s contracts; information about KRC’s relationships, dealings or contracts with its suppliers and/or vendors; confidential personal and personnel information about KRC’s former and current employees (including without limitation the circumstances of any former employee’s departure from the company) and their family members; and all other information of a confidential, privileged, proprietary, and/or trade secret nature.

10.3    Mr. Rosetta and KRC acknowledge that in the course of his employment, Mr. Rosetta acquired knowledge of, or otherwise was privy to, Confidential Information, which he would not have had knowledge of, or otherwise have been privy to, but for employment with KRC. In addition to all of the other covenants and undertakings set forth herein, and without limitation, Mr. Rosetta on behalf of himself and his attorneys, agents, representatives and assigns, or indirectly through any third party or anyone acting in concert with him, understands, acknowledges and agrees that he, his attorneys, agents, representatives and assigns, or any third party at his direction, has a continuing obligation after the Separation Date, not to take, appropriate, disclose, provide, publish, transmit or use Confidential Information in any manner whatsoever for any purpose or for any other person or entity including without limitation any competitor of KRC, or while he is employed by, or performing consulting services for, any other person or entity, and that he nor any third party at his direction has not done so prior to executing the Agreement, except as may be expressly provided for by federal, state or local laws.

10.4    Mr. Rosetta acknowledges and agrees that the fact of the Agreement, the negotiations leading to the Agreement and its terms constitute confidential information of KRC for purposes of the Confidentiality Agreement. As a limited and express exception to the restrictions of the Confidentiality Agreement as to such information regarding this Agreement, the parties agree that (i) Mr. Rosetta may make disclosures about this Agreement to his spouse, attorneys and accountants, and may make statements which are consistent with the statements in the press release and Section 9.2, above; and (ii) KRC may disclose the existence of an amicable agreement as reasonably needed in the ordinary course of business to employees and to the Board of Directors, and may disclose the Agreement as required by law (without limitation including in any anticipated 8-K or 10-Q filings).

10.5    In the event that Mr. Rosetta shall have retained Confidential Information in the course and scope of his employment, he shall promptly return any such Confidential Information to KRC on the Separation Date. Mr. Rosetta Further represents that he understands and agrees that the protections of Confidential Information continue post-employment without limitation, except as to any Confidential Information that, for any lawful reason, loses its status as “confidential.”

10.6    Mr. Rosetta agrees that he shall advise KRC promptly if he becomes aware of any attempt to cause Confidential Information to be disclosed. The confidentiality obligations herein do not prohibit disclosure to the extent necessary to comply with a court order or subpoena or any other obligation imposed by law. Should Mr. Rosetta receive a court order, subpoena or request from a government agency pertaining to information that reasonably appears to be Confidential Information, Mr. Rosetta agrees to promptly, and at least five (5) business days prior to any disclosure, notify KRC’s Corporate Counsel of such request and transmit to KRC a copy of the court order, subpoena, or government request.

10.7    Further, the parties represent and agree that this Agreement is intended to fully comply with the Defend Trade Secrets Act of 2016. Accordingly, Mr. Rosetta acknowledges and understands the following:

(a)    An individual may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding.

(b)    Further, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the employer’s trade secrets to the attorney and use the trade secret information in the court proceeding if the individual: (a) files any document containing the trade secret under seal; and (b) does not disclose the trade secret, except pursuant to court order.

11.1    Any remedy for any threatened breach or breach provided for in the Agreement, and any remedy at law or in equity including without limitation damages and/or a temporary

restraining order and/or a preliminary or permanent injunction for the purpose of restraining the other party from engaging in prohibited activities or providing such other relief as may be required to specifically enforce the terms of this Agreement, may be pursued in arbitration by or for the benefit of either party or any of their respective Released Parties, and nothing stated herein shall restrict in any way such remedies. KRC shall be entitled, as the prevailing party, to recover the sums paid to Mr. Rosetta provided for in Section 2.1.1, except for the sum of One Hundred Fifty Thousand Dollars ($150,000.00), which sum shall be retained as consideration for the releases herein, and nothing stated herein shall restrict the remedy provided for in Section 2.1.3.

11.2    All remedies expressly provided for in the Agreement are in addition to any and all other remedies existing at contract, law or in equity. Resort to any remedy provided for in the Agreement or the Confidentiality Agreement, or provided for by contract, law or in equity, will not prevent concurrent or subsequent award of other appropriate remedies or preclude a recovery of monetary damages and other compensation or restitution. The prevailing party shall be entitled to recover its reasonable attorneys’ fees, costs and expenses (including the fees of experts or expert witnesses).

11.3    The parties agree that any action, dispute, controversy or claim (collectively, “Dispute”) arising out of or in any way relating to this Agreement or to the Confidentiality Agreement, or to the breach or threatened breach thereof, or to any other matters between the parties including without limitation the pursuit of relief under Section 2.1.3 or Section 11, or Mr. Rosetta’s employment with KRC, shall be resolved to the fullest extent permitted by law by final and binding arbitration administered by JAMS before a single neutral arbitrator. The arbitration will be conducted pursuant to the Employment Arbitration Rules & Procedures and subject to the JAMS Policy on Employment Arbitration Minimum Standards of Procedural Fairness. The rules may be accessed at: https://www.jamsadr.com/rules-employment-arbitration/english. Under these rules, the parties acknowledge and agree that (a) the prevailing party may recover any and all damages and other relief under contract, at law or in equity, that would otherwise be available at law or in equity including without limitation the relief provided for in Section 2.1.3 or Section 11, herein; (b) each party is entitled to discovery sufficient to adequately arbitrate the Dispute, including access to essential documents and witnesses; (c) KRC shall pay the entire cost of the arbitrator and the arbitration forum costs; (d) the arbitrator must issue a written decision stating the essential findings and conclusions on which the award is based, and sufficient to allow for judicial review to the fullest extent permitted by law including for legal error; and (e) except as required for judicial review or in response to court order, any and all proceedings shall be maintained in the strictest confidence by the parties and their representatives, the arbitrator and any other participants in the arbitration proceedings. Each of the parties hereby consent to the jurisdiction of the arbitrator and to JAMS to administer the arbitration, and to submit to said jurisdiction. Accordingly, the parties waive their respective rights to a jury trial. The parties agree that this Section 11 amends, in relevant part, the Confidentiality Agreement, as it provides for binding arbitration. However, for the avoidance of doubt, the venue of the arbitration, and as set forth in the Confidentiality Agreement, shall remain in the County of Los Angeles. The parties agree that this Arbitration Agreement shall be governed by California Civil Procedure Code section 1280 et seq. and the Federal Arbitration Act, 9 U.S.C. section 1, et. seq.

This Agreement, along with the previously executed Confidentiality Agreement and Indemnification Agreement, dated April 30, 2018, constitute an integrated written contract expressing the entire agreement between KRC and Mr. Rosetta as to its subject matter. All prior and contemporaneous discussions, negotiations and writings have been and are merged with and integrated into, and are superseded by, this Agreement. No representations, promises, agreements or understandings, written or oral, not contained herein shall be of any force or effect. The Agreement cannot be modified except by a writing executed by the Parties hereto. Nothing stated herein shall amend or change any provision of the Confidentiality Agreement which remains in full force and effect and are fully enforceable.

If any provision (or portion thereof) of this Agreement is declared by an arbitrator or court of competent jurisdiction to be invalid or unenforceable, the remaining provisions (including other portions of a provision having an invalid portion) shall remain in full force and effect and, to the extent possible, the disputed provision shall be construed so that it may be valid and enforceable.

No failure or delay in exercising any right, power or privilege in respect of this Agreement shall act as a waiver to a later demand for full and complete performance.

Construction and interpretation of this Agreement shall at all times and in all respects be governed by the laws of the State of California, without regard to the rules or principles of conflicts or choice of law that might look to any jurisdiction outside of California.

KRC and Mr. Rosetta each represent, warrant and agree as follows:

16.1    Each of the parties has received, or has been given the opportunity to receive, prior independent legal advice from legal counsel and tax advisors of their choice with respect to the advisability of entering into this Agreement, and the taxability of any payments set forth herein, and therefore no ambiguity shall be resolved against any party by virtue of having participated in the drafting of this Agreement.

include the plural, the plural shall include the singular, and any gender shall include all other genders and the neutral. Where specific language is used to clarify by example a general statement contained herein, such specific language shall not be deemed to modify, limit or restrict in any manner the construction of the general statement to which it relates.

This Agreement shall inure to the benefit of and be binding upon KRC and its respective successors and assigns and any such successor or assignee shall be deemed substituted for KRC under the terms of this Agreement for all purposes.
