<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">Section 145 of the General Corporation Law of the State of Delaware (&#8220;Section 145&#8221;), as the same exists or may hereafter be amended (the &#8220;General Corporation Law&#8221;) provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorney&#8217;s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation&#8217;s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful.</p>

<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, arising out of such person&#8217;s status as such, whether or not the corporation would otherwise have the power to indemnify such person against such liability under Section 145.</p>

<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">The Registrant&#8217;s Amended and Restated Certificate of Incorporation contains certain provisions permitted under the General Corporation Law relating to the liability of directors. These provisions eliminate a director&#8217;s personal liability for monetary damages resulting from a breach of fiduciary duty as a director to the fullest extent permitted by the General Corporation Law.</p>

<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">The Registrant&#8217;s Amended and Restated Bylaws provide that the Registrant shall indemnify and hold harmless, to the fullest extent permitted by the General Corporation Law, its directors and officers (and may indemnify its employees and other agents) involved in any action, lawsuit or proceeding by reason of the fact that he or she is or was a director or officer (or employee or agent, if applicable) of the Registrant. The Registrant&#8217;s Amended and Restated Bylaws also permit the Registrant to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in such capacity, regardless of whether the Registrant would have the power to indemnify him or her against such liability under the General Corporation Law.</p>

<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">The foregoing is only a general summary of certain aspects of Delaware law, and the Registrant&#8217;s Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws dealing with indemnification of directors and officers, and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of Section 145 of the General Corporation Law and the Registrant&#8217;s Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">The Registrant&#8217;s directors and officers are covered by insurance maintained by the Registrant against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act. In addition, the Registrant has entered into agreements with its directors and officers providing indemnification of such directors and officers by the Registrant to the fullest extent permitted by law, subject to certain limited exceptions.</p>

Item 6. Indemnification of Directors and Officers
Section 145 of the General Corporation Law of the State of Delaware ("Section 145"), as the same exists or may hereafter be amended (the "General Corporation Law") provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation's best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful.
Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, arising out of such person's status as such, whether or not the corporation would otherwise have the power to indemnify such person against such liability under Section 145.
The Registrant's Amended and Restated Certificate of Incorporation contains certain provisions permitted under the General Corporation Law relating to the liability of directors. These provisions eliminate a director's personal liability for monetary damages resulting from a breach of fiduciary duty as a director to the fullest extent permitted by the General Corporation Law.
The Registrant's Amended and Restated Bylaws provide that the Registrant shall indemnify and hold harmless, to the fullest extent permitted by the General Corporation Law, its directors and officers (and may indemnify its employees and other agents) involved in any action, lawsuit or proceeding by reason of the fact that he or she is or was a director or officer (or employee or agent, if applicable) of the Registrant. The Registrant's Amended and Restated Bylaws also permit the Registrant to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in such capacity, regardless of whether the Registrant would have the power to indemnify him or her against such liability under the General Corporation Law.
The foregoing is only a general summary of certain aspects of Delaware law, and the Registrant's Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws dealing with indemnification of directors and officers, and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of Section 145 of the General Corporation Law and the Registrant's Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws.
The Registrant's directors and officers are covered by insurance maintained by the Registrant against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act. In addition, the Registrant has entered into agreements with its directors and officers providing indemnification of such directors and officers by the Registrant to the fullest extent permitted by law, subject to certain limited exceptions.

To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
Provided
,
however
, that paragraphs (1)(a)(i) and (1)(a)(ii) of this Item 9 do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference herein.
(b)
That, for the purpose of determining any liability under the Securities Act, each such post effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
2.
The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
3.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Kirkland, State of Washington, on August 3, 2020.
