4.1Organization, Good Standing and Qualification. The Investor is a corporation duly organized, validly existing and in good standing under the laws of Washington.

4.2Authorization. The Investor has full power and authority to enter into this Agreement and the Rights Agreement, and each such agreement constitutes a valid and legally binding obligation of the Investor, enforceable in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies, and (iii) to the extent the indemnification provisions contained in the Rights Agreement may be limited by applicable federal or state securities laws.

4.3Purchase Entirely for Own Account. By the Investor’s execution of this Agreement, the Investor hereby confirms, that the Shares to be received by the Investor will be acquired for investment for the Investor’s own account, not as a nominee or agent, and not with a view to the distribution of any part thereof, and that the Investor has no present intention of selling, granting any participation in, or otherwise distributing the same, except as permitted by applicable federal or state securities laws. By executing this Agreement, the Investor further represents that the Investor does not

have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Shares.

4.4Disclosure of Information. The Investor believes it has received all the information it considers necessary or appropriate for deciding whether to purchase the Shares. The Investor further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares and the business, properties, prospects and financial condition of the Company. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 3 of this Agreement or the right of the Investor to rely thereon.

4.5Investment Experience. The Investor is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Shares. Investor also represents it has not been organized for the purpose of acquiring the Shares.

4.6Accredited Investor. The Investor is an “accredited investor” within the meaning of Regulation D, Rule 501(a), promulgated by the SEC under the Securities Act, as presently in effect.

4.7Brokers or Finders.

4.8Restricted Securities The Investor understands that the Shares will be characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act, only in certain limited circumstances. In this connection, the Investor represents that it is familiar with Rule 144 promulgated under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

4.9Legends. The Investor understands that the Shares may bear one or all of the following legends:

(a)“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF ANY OTHER JURISDICTIONS. THESE SECURITIES MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT, APPLICABLE STATE SECURITIES LAWS (PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM). INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.”

(b)“THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO A 365-DAY MARKET STANDOFF RESTRICTION AS SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. AS A RESULT OF SUCH AGREEMENT,

THESE SECURITIES MAY NOT BE TRADED PRIOR TO 365 DAYS AFTER THE EFFECTIVE DATE OF ANY PUBLIC OFFERING OF THE COMMON STOCK OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES OF THESE SHARES.”

(c)Any legend required by applicable state “blue sky” securities laws, rules and regulations.

Following the expiration of the Market Stand-Off Period (as defined below), in the event that the Market Stand-Off Shares become registered under the Securities Act or are eligible to be transferred without restriction in accordance with Rule 144 under the Securities Act, the Company shall (x) instruct the Company’s transfer agent to issue new uncertificated (book-entry) instruments representing such Market Stand-Off Shares, which shall not contain such portion of the above legend that is no longer applicable, (y) take all actions with the Company’s transfer agent reasonably requested by the Investor to permit such un-legended Market Stand-Off Shares to be deposited into the account specified by the Investor to the Company in writing, and (z) instruct the Company’s transfer agent to cause such Market Stand-Off Shares to be assigned the same CUSIP as the shares of Class A Common Stock that are then traded on the principal stock exchange on which the shares of Class A Common Stock are then listed; provided that, (1) the Investor (or the Designee, as applicable) surrenders to the Company the previously issued uncertificated (book-entry) instruments representing the Market Stand-Off Shares and (2) the Investor (or the Designee, as applicable) delivers a customary representation letter requested by the Company’s transfer agent.

4.10Market Stand-Off Agreement; Lock-Up Agreement.

In order to enforce this covenant, the Company shall have the right to place restrictive legends on the book-entry accounts representing the Shares and to impose stop transfer instructions with respect to the Shares until the end of such period. The provisions of this Section 4.10 shall not apply to shares acquired in market purchases (subject to Section 4.11) following the Qualified IPO. In addition, the Investor hereby confirms that it has executed and delivered to the Underwriters the lock-up agreement provided by the Company (the “Lock-Up Agreement”). The Lock-Up Agreement is in full force and effect, and following the consummation of the transactions contemplated by this Agreement will remain in full force and effect, including with respect to the Shares. For purposes of this Agreement, the term “Affiliates” means any individual or entity that directly or indirectly controls, is controlled by, or is under common control with the individual or entity in question.

4.11Standstill. Unless approved in advance in writing by the board of directors of the Company, the Investor agrees that, neither they nor any of their Representatives (as defined below) acting on behalf of or in concert with the Investor will, until 365 days following the effective date of the Qualified IPO (“Standstill Expiration”), directly or indirectly:
