EXHIBIT A

EMPLOYEE PROPRIETARY INFORMATION

AND INVENTIONS AGREEMENT

In consideration of my employment or continued employment by
 (the Company), and the compensation now and hereafter paid to me, I hereby agree as follows:

1. NONDISCLOSURE.

1.1 Promise to Provide Proprietary Information; Recognition of Companys Rights; Nondisclosure. The Company agrees that upon the commencement of my employment, it will provide me with Proprietary Information (defined
below) of the Company that will enable me to optimize the performance of my duties to the Company. In exchange, I agree that at all times during my employment and thereafter, I will hold in strictest confidence and will not disclose, use, lecture
upon or publish any of the Companys or its parent, affiliates or subsidiaries Proprietary Information (defined below), except as such disclosure, use or publication may be required in connection with my work for the Company, or unless an
officer of the Company expressly authorizes such in writing. I will obtain Companys written approval before publishing or submitting for publication any material (written, verbal, or otherwise) that relates to my work at Company and/or
incorporates any Proprietary Information. I hereby assign to the Company any rights I may have or acquire in such Proprietary Information and recognize that all Proprietary Information shall be the sole property of the Company and its assigns.

1.2 Proprietary Information. The term Proprietary Information shall mean any and all confidential and/or
proprietary knowledge, data or information applicable to the business of the Company. By way of illustration but not limitation, Proprietary Information includes (a) trade secrets, inventions, mask works, ideas, processes,
formulas, source and object codes, data, programs, other works of authorship, know-how, improvements, discoveries, developments, designs and techniques (hereinafter collectively referred to as Inventions); and
(b) information regarding plans for research, development, new products, marketing and selling, business plans, budgets and unpublished financial statements, licenses, prices and costs, suppliers and customers; and (c) information
regarding the skills and compensation of other employees of the Company. Notwithstanding the foregoing, it is understood that, at all such times, I am free to use information which is generally known in the trade or industry, which is not gained as
result of a breach of this Agreement, and my own, skill, knowledge, know-how and experience to whatever extent and in whichever way I wish.

1.3 Third Party Information. I understand, in addition, that the Company has received and in the future will receive from third parties confidential or proprietary information (Third Party Information) subject to a
duty on the Companys part to maintain the confidentiality of such information and to use it only for certain limited purposes. During the term of my employment and thereafter, I will hold Third Party Information in the strictest confidence and
will not disclose to anyone (other than Company personnel who need to know such information in connection with their work for the Company) or use, except in connection with my work for the Company, Third Party Information unless expressly authorized
by an officer of the Company in writing.

1.4 No Improper Use of Information of Prior Employers and Others. During my
employment by the Company I will not improperly use or disclose any confidential information or trade secrets, if any, of any former employer or any other person to whom I have an obligation of confidentiality, and I will not bring onto the premises
of the Company any unpublished documents or any property belonging to any former employer or any other person to whom I have an obligation of confidentiality unless consented to in writing by that former employer or person. I will use in the
performance of my duties only information which is generally known and used by persons with training and experience comparable to my own, which is common knowledge in the industry or otherwise legally in the public domain, or which is otherwise
provided or developed by the Company.

2. ASSIGNMENT OF INVENTIONS.

2.1 Proprietary Rights. The term Proprietary Rights shall mean all trade secret, patent, copyright, mask work and
other intellectual property rights throughout the world.

2.2 Prior Inventions.Inventions, if any, patented or unpatented,
which I made prior to the commencement of my employment with the Company are excluded from the scope of this Agreement. To preclude any possible uncertainty, I have set forth on Exhibit B-1 (Previous Inventions) attached hereto a complete
list of all Inventions that I have, alone or jointly with others, conceived, developed or reduced to practice or caused to be conceived, developed or reduced to practice prior to



|                                  |  |        |  |        
|--------------------------------- |  | ------ |  | -------
|Employment agreement Confidential |  | Page 6 |  | 5/21/04



---

the commencement of my employment with the Company, that I consider to be my property or the property of third parties
and that I wish to have excluded from the scope of this Agreement (collectively referred to as Prior Inventions). If disclosure of any such Prior Invention would cause me to violate any prior confidentiality
agreement. I understand that I am not to list such Prior Inventions in Exhibit B-1 but am only to disclose a cursory name for each such invention, a listing of the party(ies) to whom it belongs and the fact that full disclosure as to
such inventions has not been made for that reason. A space is provided on Exhibit B-1 for such purpose. If no such disclosure is attached, I represent that there are no Prior Inventions. If, in the course of my employment with the Company, I
incorporate a Prior Invention into a Company product, process or machine, the Company is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with rights to sublicense through multiple tiers of
sublicensees) to make, have made, modify, use and sell such Prior Invention. Notwithstanding the foregoing, I agree that I will not incorporate, or permit to be incorporated, Prior Inventions in any Company Inventions without the Companys
prior written consent.

2.3 Assignment of Inventions. Subject to Sections 2.4, and 2.6, I hereby assign and agree to assign in the
future (when any such Inventions or Proprietary Rights are first reduced to practice or first fixed in a tangible medium, as applicable) to the Company all my right, title and interest in and to any and all Inventions (and all Proprietary Rights
with respect thereto) whether or not patentable or registrable under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or jointly with others, during the period of my employment with the Company.
Inventions assigned to the Company, or to a third party as directed by the Company pursuant to this Section 2, are hereinafter referred to as Company Inventions.

2.4 Nonassignable Inventions. I recognize that, in the event of a specifically applicable state law, regulation, rule, or public policy
(Specific Inventions Law), this Agreement will not be deemed to require assignment of any invention which qualifies fully for protection under a Specific Inventions Law by virtue of the fact that any such invention
was, for example, developed entirely on my own time without using the Companys equipment, supplies, facilities, or trade secrets and neither related to the Companys actual or anticipated business, research or development, nor resulted
from work performed by me for the Company. In the absence of a Specific Inventions Law, the preceding sentence will not apply.

2.5
Obligation to Keep Company Informed. During the period of my employment and for six (6) months after termination of my employment with the Company, I will promptly disclose to the Company fully and in writing all Inventions authored,
conceived or reduced to practice by me, either alone or jointly with others. In addition, I will promptly disclose to the Company all patent applications filed by me or on my behalf within a year after termination of employment. At the time of each
such disclosure, I will advise the Company in writing of any Inventions that I believe fully qualify for protection under the provisions of a Specific Inventions Law; and I will at that time provide to the Company in writing all evidence necessary
to substantiate that belief. The Company will keep in confidence and will not use for any purpose or disclose to third parties without my consent any confidential information disclosed in writing to the Company pursuant to this Agreement relating to
Inventions that qualify fully for protection under a Specific Inventions Law. I will preserve the confidentiality of any Invention that does not fully qualify for protection under a Specific Inventions Law.

2.6 Government or Third Party. I also agree to assign all my right, title and interest in and to any particular Company Invention to a third
party, including without limitation the United States, as directed by the Company.

2.7 Works for Hire. I acknowledge that
all original works of authorship which are made by me (solely or jointly with others) within the scope of my employment and which are protectable by copyright are works made for hire, pursuant to United States Copyright Act (17 U.S.C.,
Section 101).

2.8 Enforcement of Proprietary Rights. I will assist the Company in every proper way to obtain, and from time to
time enforce, United States and foreign Proprietary Rights relating to Company Inventions in any and all countries. To that end I will execute, verify and deliver such documents and perform such other acts (including appearances as a witness) as the
Company may reasonably request for use in applying for, obtaining, perfecting, evidencing, sustaining and enforcing such Proprietary Rights and the assignment thereof. In addition, I will execute, verify and deliver assignments of such Proprietary
Rights to the Company or its designee. My obligation to assist the Company with respect to Proprietary Rights relating to such Company Inventions in any and all countries shall continue beyond the termination of my employment, but the Company shall
compensate me at a reasonable rate after my termination for the time actually spent by me at the Companys request on such assistance.

In the event the Company is unable for any reason, after reasonable effort, to secure my signature on any document needed in connection with the actions specified in the preceding paragraph, I hereby irrevocably designate and appoint the
Company and its duly authorized officers and agents as my agent and attorney in fact, which appointment is coupled with an interest, to act for and in my behalf to execute, verify and file any such documents and to do all other lawfully permitted
acts to



|                                  |  |        |  |        
|--------------------------------- |  | ------ |  | -------
|Employment agreement Confidential |  | Page 7 |  | 5/21/04



---

further the purposes of the preceding paragraph with the same legal force and effect as if executed by me. I hereby waive
and quitclaim to the Company any and all claims, of any nature whatsoever, which I now or may hereafter have for infringement of any Proprietary Rights assigned hereunder to the Company.

3. RECORDS. I agree to keep and maintain adequate and current records (in the form of notes, sketches, drawings and in any other form that may be required by the Company) of all
Proprietary Information developed by me and all Inventions made by me during the period of my employment at the Company, which records shall be available to and remain the sole property of the Company at all times.

4. NO CONFLICTING OBLIGATION. I represent that my performance of all the terms of this Agreement and as an employee
of the Company does not and will not breach any agreement to keep in confidence information acquired by me in confidence or in trust prior to my employment by the Company. I have not entered into, and I agree I will not enter into, any agreement
either written or oral in conflict herewith.

5. COVENANT NOT TO COMPETE. During my
employment with the Company and for two (2) years following the termination of my employment with the Company for any reason, I agree that I will not directly or indirectly, whether as an officer, director, stockholder, partner, proprietor,
associate, representative, consultant, or in any capacity whatsoever engage in, become financially interested in, be employed by or have any business connection with any other person, corporation, firm, partnership or other entity whatsoever known
by me to compete directly with the Company, anywhere in the world, in any line of business engaged in (or planned to be engaged in) by the Company; provided, however, that I may purchase or otherwise acquire up to (but not more than) one percent
(1%) of any class of securities of any enterprise (but without participating in the activities of such enterprise) if such securities are listed on any national or regional securities exchange or have been registered under Section 12(g) of the
Securities Exchange Act of 1934, as amended (the Exchange Act).

I acknowledge that I will derive significant value from the Companys
agreement in Section 1.1 to provide me the Proprietary Information of the Company that will enable me to optimize the performance of my duties for the Company. I further acknowledge that my fulfillment of the obligations contained in this
Agreement, including without limitation my obligation not to use or disclose the Companys Proprietary Information other than for the Companys benefit and my obligation not to compete, are necessary to protect the Companys
Proprietary Information and, consequently, to preserve the value and goodwill of the Company. I further acknowledge that the time, geographic and scope limitations of my non-competition obligation are reasonable, especially in light of the
Companys desire to protect its Proprietary Information, and that I will not be precluded from gainful employment if I am obligated not to compete with the Company as described above.

6. RETURN OF COMPANY DOCUMENTS. When I leave the employ of the Company, I will deliver to the Company
any and all drawings, notes, memoranda, specifications, devices, formulas, and documents, together with all copies thereof, and any other material containing or disclosing any Company Inventions, Third Party Information or Proprietary Information of
the Company. I further agree that any property situated on the Companys premises and owned by the Company, including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time
with or without notice. Prior to leaving, I will cooperate with the Company in completing and signing the Companys termination statement.

7.
LEGAL AND EQUITABLE REMEDIES. Because my services are personal and unique and because I may have access to and become acquainted with the Proprietary Information of the Company, the
Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance or other equitable relief, without bond and without prejudice to any other rights and remedies that the Company may have for a
breach of this Agreement.

8. NOTICES. Any notices required or permitted hereunder shall be given to the appropriate party at the
address specified below or at such other address as the party shall specify in writing. Such notice shall be deemed given upon personal delivery to the appropriate address or if sent by certified or registered mail, three (3) days after the
date of mailing.

9. NOTIFICATION OF NEW EMPLOYER. In the event that I leave the employ
of the Company, I hereby consent to the notification of my new employer of my rights and obligations under this Agreement.

10. GENERAL
PROVISIONS.

10.1 Governing Law; Consent to Personal Jurisdiction. This Agreement will be governed by and
construed according to the laws of the State of Texas, as such laws are applied to agreements entered into and to be performed entirely within Texas between Texas residents. I hereby expressly consent to the personal jurisdiction of the state and
federal courts located in Austin, Travis County, Texas, for any arbitration or lawsuit filed there against me by Company arising from or related to this Agreement.

10.2 Severability. In case any one or more of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect the other provisions of this Agreement,



|                                  |  |        |  |        
|--------------------------------- |  | ------ |  | -------
|Employment agreement Confidential |  | Page 8 |  | 5/21/04



---

and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained
herein. If moreover, any one or more of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing it, so as
to be enforceable to the extent compatible with the applicable law as it shall then appear.

10.3 Successors and Assigns. This
Agreement will be binding upon my heirs, executors, administrators and other legal representatives and will be for the benefit of the Company, its successors, and its assigns.

10.4 Survival. The provisions of this Agreement shall survive the termination of my employment and the assignment of this Agreement by the Company
to any successor in interest or other assignee.

10.5 Waiver. No waiver by the Company of any breach of this Agreement shall be a
waiver of any preceding or succeeding breach. No waiver by the Company of any right under this Agreement shall be construed as a waiver of any other right. The Company shall not be required to give notice to enforce strict adherence to all terms of
this Agreement.

10.6 Entire Agreement. The obligations of this Agreement shall apply to any time during which I was previously
employed, or am in the future employed, by the Company. Except as otherwise provided in the Employment and Non Solicitation Agreement, this Agreement is the final, complete and exclusive agreement of the parties with respect to the subject matter
hereof and supersedes and merges all prior discussions between us. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing and signed by the party to be charged. Any
subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement.

This Agreement
shall be effective as of the first day of my employment with the Company, namely: 5/24/2004.
