Exhibit 10.21

CONSULTING AGREEMENT

THIS CONSULTING AGREEMENT is entered into as of January 3, 2013 (“Effective Date”) between EASIC CORPORATION, a Delaware corporation (the “Company”), and MIKE KOUREY (“Advisor”).

R E C I T A L S

WHEREAS, the Company anticipates that its Board of Directors (the “Board”) shall appoint Advisor to serve on the Board until his successor is duly elected and qualified; and

WHEREAS, the Company and Advisor desire to enter into this Agreement to set forth the terms of Advisor’s service and compensation arrangement with the Company.

NOW, THEREFORE, for good and valuable consideration, receipt of which is hereby acknowledged, the Company and Advisor agree as follows:

Advisor shall provide consulting services to the Company with respect to the Company’s business and operations and such other service as may be mutually agreed upon by the Company and Advisor (the “Consulting Services”); and, upon appointment to the Board, shall serve as a member of its Board in accordance with the duties and obligations set forth under the Delaware General Corporation Law (the “DGCL”), including without limitation, attendance at Board meetings, participation in subcommittees of the Board, and consultation with board members and officers of the Company as necessary or appropriate (“Board Services” and together with the Consulting Services, the “Services”). In providing such Consulting Services, Advisor shall devote 0.5 days per week to the Company’s business and operations at the Company’s offices, and be also available at other times by telephone as reasonably required by the Company.

In full consideration for Advisor’s timely and satisfactory performance of the Services, subject to approval by the Company’s Board, Advisor will be granted an option to purchase shares of Company common stock (the “Shares”) at an exercise price equal to the fair market value on the date of grant, as determined by the Board, with the number of Shares calculated to equal 0.5% of the Company’s total outstanding shares calculated on a Fully diluted Basis as of the closing of the Company’s Series A-2 Preferred Stock Financing, occurring on or around January 26, 2013. “Fully diluted Basis” shall include all common, preferred and any other types of voting equity issued or outstanding, including stock options outstanding or shares reserved for issuance pursuant to stock options yet to be granted, and any warrants outstanding. The option will be a nonqualified stock option and will be subject to the terms of the Company’s 2010 Equity Incentive Plan (the “Plan”) and standard form of Stock Option Agreement. Subject to Advisor’s Continuous Service (as defined in the Plan), the Shares shall vest monthly over a twelve (12) month period beginning on the Effective Date and the option shall be early-exercisable pursuant to the Company’s standard form of early exercise stock purchase agreements. Moreover, in the event of (i) a sale, lease or other disposition of all or substantially all of the assets of the Company, (ii) a consolidation or merger of the Company with or into any other corporation or other entity or person, or any other corporate reorganization, in which the shareholders of the Company immediately prior to such consolidation, merger or reorganization, own less than 50% of the Company’s outstanding voting power of the surviving entity (or its parent) following the consolidation, merger or reorganization or (iii) any transaction (or series of related transactions involving a person or entity, or a group of affiliated persons

or entities) in which in excess of fifty percent (50%) of the Company’s outstanding voting power is transferred (each of the foregoing, a “Change of Control”), then the vesting of the Shares, along with the unvested portion of any other stock options held by the Consultant, shall be accelerated in full, subject to the terms of the Plan and the Consultant’s Continuous Service through the date of such Change of Control.

In addition to Advisor’s obligations, duties and restrictions under the DGCL that arise from Advisor’s positon as a member of the Board, Advisor also recognizes that Advisor will be exposed to, have access to and be engaged in the development of information (including all tangible and intangible manifestations) regarding the patents, copyrights, trademarks, trade secrets, technology, strategic sales/marketing plans, and business of the Company and agrees as follows:

(a) All Proprietary Information (as defined below), whether presently existing or developed in the future, shall be the sole property of the Company and its assigns. In addition, the Company and its assigns shall be the sole owner of all intellectual property and other rights in connection with such Proprietary Information. The term “Proprietary Information” shall mean all inventions, works of authorship, trade secrets, business plans, confidential knowledge, data or any other proprietary information of the Company. By way of illustration but not limitation, “Proprietary Information” includes, without limitation, (i) inventions, ideas, samples, designs, applications, drawings, methods or processes, formulas, trade secrets, data, source and object codes, know-how, improvements, discoveries, developments, designs and techniques; and (ii) information regarding plans for research, development, new products and service offerings, marketing and selling, business plans, budgets and unpublished financial statements, licenses, sales, pricing, profits and costs, distribution arrangements, suppliers and customers, marketing, customer and a partner strategies, business development plans, customer and partner lists, and information regarding the skills and compensation of employees of the Company and the Company’s internal organization.

(b) During the term of this Agreement and after its termination, Advisor will keep in confidence and trust all Proprietary Information and shall not reproduce, use or disclose any Proprietary Information or anything related to such information without the prior written consent of the Company, except as required in the ordinary course of performing the Services.

(c) Advisor agrees to promptly disclose to the Company and hereby assigns to the Company, or its designee, all right, title and interest in and to all inventions, original works of authorship, developments, concepts, know how, improvements or trade secrets, whether or not patentable, that Advisor may solely or jointly conceive or develop or reduce to practice during the term of this Agreement that arise from the Services. Advisor shall execute all such documents and take all such actions as are reasonably requested by the Company to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company, or its designee’s, rights in the inventions and any intellectual property rights relating thereto.

(b) Advisor represents that neither the execution of this Agreement nor the performance of Advisor’s obligation under this Agreement will result in a violation or breach of any other agreement by which Advisor is bound. The Company represents that this Agreement has been duly authorized and executed and is a valid and legally binding obligation of the Company, subject to no conflicting agreements.

(d) This Agreement replaces all previous agreements and the discussions relating to the subject matters hereof and constitutes the entire agreement between the Company and Advisor with respect to the subject matter of this Agreement. This Agreement may not be modified in any respect by any verbal statement, representation, or agreement made by any employee, officer, or representative of the Company, or by any written documents unless it is signed by an executive officer of the Company and by Advisor.

(e) The provisions of this Agreement are severable and if any one or more provisions may be determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions and any partially unenforceable provisions to the extent enforceable, shall nevertheless be binding and enforceable.
