NOW, THEREFORE, the parties agree as follows:

1. Covenant Not to Compete.

(a) Shareholder agrees that, for a period of three (3) years from the Effective Time of the Merger (as defined in the Reorganization Agreement) and for so long thereafter as he is employed by or serves as a consultant to Finisar (the "Noncompetition Period"), he will not, directly or indirectly, individually or as an owner, partner, shareholder, joint venturer, corporate officer, director, employee, consultant, principal, agent, trustee or licensor, or in any other similar capacity whatsoever of or for any person, firm, partnership, company or corporation (other than Finisar), (a) own, manage, operate, sell, control or participate in the ownership, management, operation, sales or control of (i) any business that competes with the Business of Sensors, as currently being conducted or as then being conducted (whether through stand-alone products or broader products that include equivalent functionality), and/or (ii) any business engaged in the research, development, design, marketing, sales, manufacture or licensing of products that are substantially similar to or competitive with any products of Sensors (whether through stand-alone products or broader products that include equivalent functionality); (b) accept employment with a customer of Sensors with the intent or purpose of depriving Sensors of business performed by Sensors by transferring such business to a department, division or affiliate of the customer or to a third party; or (c) request or advise any of the customers, suppliers or other business contacts of Sensors with which Shareholder had contact while employed by Sensors to withdraw, curtail, cancel or not increase their business with Sensors. Notwithstanding the foregoing, (i) Shareholder may be

employed by an entity which engages in such activities provided that Shareholder is employed by and performs all of his services exclusively for a division or other business unit of such entity that is not engaged in any such activities and (ii) Shareholder is permitted to own as a passive investor up to a five (5%) interest in any publicly traded entity. Shareholder agrees to notify Finisar of each employment or consulting position he accepts during the Noncompetition Period (including the name and address of the hiring party) and will, upon request by Finisar, describe in reasonable detail the nature of his duties in each such position.

(b) Notwithstanding the provisions of Paragraph 1(a) above, if Shareholder's employment with Finisar pursuant to the Employment Agreement of even date herewith is terminated by Finisar other than "For Cause" or by Shareholder for "Good Reason," as those terms are defined therein, the Noncompetition Period shall be the lesser of the period specified in Paragraph 1(a) or one (1) year following such termination.

2. Nonsolicitation of Employees and Consultants. During the Noncompetition Period, Shareholder agrees that he will not directly or indirectly solicit, influence, entice or encourage any person who at such time is, or who at any time in the six (6) month period prior to such time had been, an employee of or consultant to Finisar or Sensors to cease or curtail his or her relationship therewith.

3. Covenant Not to Hire. During the Noncompetition Period, Shareholder agrees that he will not directly or indirectly hire or attempt to hire, whether as an employee, consultant or otherwise, any person who at such time is, or who at any time in the six (6) month period prior to such time had been, employed by Finisar or Sensors.

4. Nondisruption; Other Matters. During the Noncompetition Period, Shareholder agrees that he will not directly or indirectly interfere with, disrupt or attempt to disrupt any past, present or prospective relationship, contractual or otherwise, between Finisar or Sensors, on the one hand, and any of their respective customers, suppliers or employees, on the other hand.

5. Equitable Relief. Shareholder acknowledges and agrees that Finisar's remedies at law for breach of any of the provisions of this Agreement would be inadequate and, in recognition of this fact, Shareholder agrees that, in the event of such breach, in addition to any remedies at law it may have, Finisar, without posting any bond, shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy that may be available. Shareholder further acknowledges that should Shareholder violate any of the provisions of this Agreement, it will be difficult to determine the amount of damages resulting to Finisar and that in addition to any other remedies it may have, Finisar shall be entitled to temporary and permanent injunctive relief without the necessity of proving damages. Notwithstanding the provisions of this Paragraph 5, Shareholder shall be entitled to contest any such proposed injunctive relief, or seek damages arising from any injunctive relief awarded to Finisar, in any court of competent jurisdiction.

6. Acknowledgement. Each of Shareholder and Finisar acknowledges and agrees that the covenants and agreements contained in this Agreement have been negotiated in good faith by the parties, are reasonable and are not more restrictive or broader than necessary to protect the interests of the parties thereto, and would not achieve their intended purpose if they were on different terms or for periods of time shorter than the periods of time provided herein or applied in more restrictive geographical areas than are provided herein. Each party further acknowledges that Finisar would not enter into the Reorganization Agreement and the transactions contemplated thereby in the absence of the covenants and agreements contained in this Agreement and that such covenants and agreements are essential to protect the value of Sensors to Finisar.

7. Separate Covenants. The covenants contained in this Agreement shall be construed as a series of separate covenants, one for each of the counties in each of the states of the United States

of America, one for each province of Canada, and one for each country outside the United States and Canada.

8. Severability. The parties agree that construction of this Agreement shall be in favor of its reasonable nature, legality and enforceability, and that any construction causing unenforceability shall yield to a construction permitting enforceability. It is agreed that the noncompetition, nonsolicitation, and nonhiring covenants and provisions of this Agreement are severable, and that if any single covenant or provision or multiple covenants or provisions should be found unenforceable, the entire Agreement and remaining covenants and provisions shall not fail but shall be construed as enforceable without any severed covenant or provision in accordance with the tenor of this Agreement. The parties specifically agree that no covenant or provision of this Agreement shall be invalidated because of overbreadth insofar as the parties acknowledge the scope of the covenants and provisions contained herein to be reasonable and necessary for the protection of Finisar and Sensors and not unduly restrictive upon Shareholder. However, should a court or any other trier of fact or law determine not to enforce any covenant or provision of this Agreement as written due to overbreadth, then the parties agree that said covenant or provision shall be enforced to the extent reasonable, with the court or such trier to make any necessary revisions to said covenant or provision to permit its enforceability and that any such limitation on the enforceability of any such covenant or provision share not effect the enforceability of any other covenant or provision of this Agreement.

9. Not an Employment Agreement. This Agreement is not, and nothing in this Agreement shall be construed as, an agreement to provide employment to Shareholder. The provisions of Paragraphs 1, 2, 3 and 4 of this Agreement shall be operative regardless of any termination of Shareholder's employment.

10. Governing Law. This Agreement is made under and shall be governed by, construed in accordance with and enforced under the internal laws of the State of New Jersey.

11. Entire Agreement. This Agreement, together with the Reorganization Agreement, constitutes and contains the entire agreement and understanding concerning the subject matter addressed herein between the parties, and supersedes and replaces all prior negotiations and all agreements proposed or otherwise, whether written or oral, concerning the subject matter hereof, and the parties hereto have made no agreements, representations or warranties relating to the subject matter of this Agreement that are not set forth herein or in the Reorganization Agreement.

12. Notices. Any notice or other communication under this Agreement shall be in writing, signed by the party making the same, and shall be delivered personally or sent by certified or registered mail, postage prepaid, addressed as follows:

14. Amendments; No Waiver.

(b) No term or condition of this Agreement shall be deemed to have been waived, nor shall there be any estoppel to enforce any provision of this Agreement, except by a statement in writing signed by the party against whom enforcement of the waiver or estoppel is sought.

15. Assignment. This Agreement may be assigned by Finisar to any affiliate of Finisar or to any nonaffiliate of Finisar that shall succeed to all or substantially all of the business and assets of Finisar, Sensors or the Business of Sensors. In the event of any such assignment, Finisar shall cause such affiliate or nonaffiliate, as the case may be, to assume the obligations of Finisar hereunder, by a written agreement addressed to Shareholder, concurrently with any assignment with the same effect as if such assignee were "Finisar" hereunder. This Agreement is personal to Shareholder, and Shareholder may not assign any rights or delegate any responsibilities hereunder.
