release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which, if known by him, must have materially affected his settlement with the debtor.

| | 10. | You and the Company understand and agree that nothing in this Agreement shall modify in any manner any indemnification and/or insurance rights you may have pursuant to the
Companys Certificate of Incorporation, Bylaws, the Indemnification Agreement between you and the Company dated May 1, 2001, or any applicable insurance policy for officers and directors liability.

other than shares you own and that are in your possession. All terms, conditions and limitations applicable to the purchase rights pursuant to the Companys Employee Stock Purchase Plan shall remain in full force and effect.

Exhibit A  PIIA

PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT



The following confirms an agreement between me Robert P. Verheecke and Blue
Coat Systems, Inc., a Delaware corporation (the Company), which is a material part of the consideration for my employment by Company:



1. I have not entered into, and I agree I will not enter into, any agreement either written or oral in conflict with this Agreement or my employment with
Company. I will not violate any agreement with or rights of any third party or, except as expressly authorized by Company in writing hereafter, use or disclose my own or any third partys confidential information or intellectual property when
acting within the scope of my employment or otherwise on behalf of Company. Further, I have not retained anything containing any confidential information of a prior employer or other third party, whether or not created by me.



2. Company shall own all right, title and interest (including patent rights,
copyrights, trade secret rights, mask work rights and all other intellectual and industrial property rights of any sort throughout the world) relating to any and all inventions (whether or not patentable), works of authorship, mask works, designs,
know-how, ideas and information made or conceived or reduced to practice, in whole or in part, by me during the term of my employment with Company to and only to the fullest extent allowed by California Labor Code Section 2870 (which is attached as
Appendix A) (collectively Inventions) and I will promptly disclose all Inventions to Company. I will also disclose anything I believe is excluded by Section 2870 so that the Company can make an independent assessment. I hereby make all
assignments necessary to accomplish the foregoing. I shall further assist Company, at Companys expense, to further evidence, record and perfect such assignments, and to perfect, obtain, maintain, enforce, and defend any rights specified to be
so owned or assigned. I hereby irrevocably designate and appoint Company as its agents and attorneys-in-fact to act for and in my behalf to execute and file any document and to do all other lawfully permitted acts to further the purposes of the
foregoing with the same legal force and effect as if executed by me. If I wish to clarify that something created by me prior to my employment that relates to Companys actual or proposed business is not within the scope of this Agreement, I
have listed it on Appendix B. If I use or (except pursuant to this Section 2) disclose my own or any third partys confidential information or intellectual property when acting within the scope of my employment or otherwise on behalf of
Company, Company will have and I hereby grant Company a perpetual, irrevocable, worldwide royalty-free, non-exclusive, sublicensable right and license to exploit and exercise all such confidential information and intellectual property rights.



3. To the extent allowed by law, paragraph 2 includes all
rights of paternity, integrity, disclosure and withdrawal and any other rights that may be known as or referred to as moral rights, artists rights, droit moral, or the like (collectively Moral
Rights). To the extent I retain any such Moral Rights under applicable law, I hereby ratify and consent to any



---

action that may be taken with respect to such Moral Rights by or authorized by Company and agree not to assert any Moral Rights with respect thereto. I will
confirm any such ratifications, consents and agreements from time to time as requested by Company.



4. I agree that all Inventions and all other business, technical and financial information (including, without limitation, the identity of and information
relating to customers or employees) I develop, learn or obtain during the term of my employment that relate to Company or the business or demonstrably anticipated business of Company or that are received by or for Company in confidence, constitute
Proprietary Information. I will hold in confidence and not disclose or, except within the scope of my employment, use any Proprietary Information. However, I shall not be obligated under this paragraph with respect to information I can
document is or becomes readily publicly available without restriction through no fault of mine. Upon termination of my employment, I will promptly return to Company all items containing or embodying Proprietary Information (including all copies),
except that I may keep my personal copies of (i) my compensation records, (ii) materials distributed to shareholders generally and (iii) this Agreement. I also recognize and agree that I have no expectation of privacy with respect to Companys
telecommunications, networking or information processing systems (including, without limitation, stored computer files, email messages and voice messages) and that my activity and any files or messages on or using any of those systems may be
monitored at any time without notice.



5. Until one year after
the term of my employment, I will not encourage or solicit any employee or consultant of Company to leave Company for any reason (except for the bona fide firing of Company personnel within the scope of my employment).



6. I agree that during the term of my employment with Company (whether or not
during business hours), I will not engage in any activity that is in any way competitive with the business or demonstrably anticipated business of Company, and I will not assist any other person or organization in competing or in preparing to
compete with any business or demonstrably anticipated business of Company.



7. I agree that this Agreement is not an employment contract for any particular term and that I have the right to resign and Company has the right to terminate my employment at will, at any time, for any or no reason,
with or without cause. In addition, this Agreement does not purport to set forth all of the terms and conditions of my employment, and, as an employee of Company, I have obligations to Company which are not set forth in this Agreement. However, the
terms of this Agreement govern over any inconsistent terms and can only be changed by a subsequent written agreement signed by the President of Company.



8. I agree that my obligations under paragraphs 2, 3, 4 and 5 of this Agreement shall continue in effect after termination of my employment, regardless of
the reason or reasons for termination, and whether such termination is voluntary or involuntary on my part, and that Company is entitled to communicate my obligations under this Agreement to any future employer or potential employer of mine. My
obligations under paragraphs 2, 3 and 4 also shall be binding upon my heirs, executors, assigns, and administrators and shall inure to the benefit of Company, it subsidiaries, successors and assigns.

9. Any dispute in the meaning, effect or validity of this Agreement shall be resolved in accordance with
the laws of the State of California without regard to the conflict of laws provisions thereof. I further agree that if one or more provisions of this Agreement are held to be illegal or unenforceable under applicable California law, such illegal or
unenforceable portion(s) shall be limited or excluded from this Agreement to the minimum extent required so that this Agreement shall otherwise remain in full force and effect and enforceable in accordance with its terms. I also understand that any
breach of this Agreement will cause irreparable harm to Company for which damages would not be a adequate remedy, and, therefore, Company will be entitled to injunctive relief with respect thereto in addition to any other remedies.



I HAVE READ THIS AGREEMENT CAREFULLY AND I UNDERSTAND AND ACCEPT THE
OBLIGATIONS WHICH IT IMPOSES UPON ME WITHOUT RESERVATION. NO PROMISES OR REPRESENTATIONS HAVE BEEN MADE TO ME TO INDUCE ME TO SIGN THIS AGREEMENT. I SIGN THIS AGREEMENT VOLUNTARILY AND FREELY, IN DUPLICATE, WITH THE UNDERSTANDING THAT ONE
COUNTERPART WILL BE RETAINED BY COMPANY AND THE OTHER COUNTERPART WILL BE RETAINED BY ME.

APPENDIX A



California Labor Code Section 2870. Application of provision providing that employee shall assign or offer to assign rights in invention to
employer.



(a) Any provision in an employment agreement
which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the
employers equipment, supplies, facilities, or trade secret information except for those inventions that either:



(1) Relate at the time of conception or reduction to practice of the invention to the employers business, or actual or demonstrably anticipated
research or development of the employer; or



(2) Result from
any work performed by the employee for his employer.



(b) To
the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is
unenforceable.
