The Employee’s rights with respect to vesting and exercise of options to purchase QLT shares will be governed by the terms of the applicable stock option plans, notices of grant and stock option agreements. Should Employee choose not to comply with any of the obligations of Section 7 during the Severance Period, all payments under this Section 4(c) shall immediately cease.

(e) No Other Rights. Except as otherwise expressly required by law (e.g., COBRA) or as specifically provided herein, all of the Employee’s rights to salary, severance, benefits, bonuses and other amounts hereunder (if any) will cease upon the termination of Employee’s employment hereunder.

(d) Unauthorized Use or Disclosure. Employee will promptly notify the Supervisor or the Board of Directors of the Company if Employee learns of any possible unauthorized use or disclosure of Proprietary Information and will cooperate fully with the Company to enforce its or its Affiliates’ rights in such information.

6. INVENTIONS AND PATENTS

(a) Definition of Inventions. For purposes of this Agreement, “Inventions” means all inventions, methods, processes, works of authorship, ideas, concepts, know-how, and trade secrets, whether or not patentable or registrable under copyright or similar laws, including: software (in any form including source code and object code), algorithms, application programming interfaces (APIs), apparatus, circuit designs and assemblies, technical and business data, databases and data collections, designs, diagrams, documentation, Records, drawings, flow charts, formulae, materials, chemical compounds, formulas, formulations, delivery methods and devices, development plans, designs and brand elements, models, procedures, protocols, schematics, specifications, techniques, test vectors, tools, user interfaces, developments and derivative works with respect to any of the foregoing, and any other forms of technology.

Employee hereby assigns to the Company, or its designee, all right, title and interest throughout the world in and to any and all Inventions that Employee conceives, makes, or reduces to specific form, either alone or jointly with others, in the course of Employee’s employment by the Company (and whether for the Company or any of its Affiliates) during the Employment Period (collectively, “Employment Inventions”). Notwithstanding the foregoing, Employee understand that this Agreement does not require assignment of any Invention to the extent such Invention qualifies for protection under Section 2870 of the California Labor Code, the current text of which is attached hereto as Appendix 2 (“Section 2870”).

(c) Disclosure of Inventions. Employee will promptly disclose to the Company all Employment Inventions. In addition, Employee will promptly disclose to the Company all Inventions that Employee conceives, makes, or reduces to specific form, either alone or jointly with others, during the period of Employee’s employment by the Company that Employee believes qualifies under Section 2870 (each, a “Section 2870 Invention”). At the time of disclosure of a Section 2870 Invention, Employee will provide to the Company in writing evidence to substantiate the belief that such Invention qualifies as a Section 2870 Invention.

To preclude any possible uncertainty over whether an Invention is a Prior Invention or an Invention that is assigned to the Company under Section 6(b), Employee has set forth on Appendix 3 a complete list of all Prior Inventions that Employee considers to be in whole or in part owned by Employee or by a third party and that Employee wishes to clarify are not assigned to the Company under Section 6(b) of this Agreement. If full disclosure of any such Prior Invention on Appendix 3 would cause Employee to violate any prior confidentiality agreement with a former employer or other third party, Employee understands that Employee is to describe such Prior Invention in Appendix 3 at the most specific level possible without violating any such prior confidentiality agreement. Without limiting Employee’s obligations under Section 5(b) or the representations under this Agreement, if Employee uses a Prior Invention in the course of his employment or incorporates a Prior Invention in any product, service or other offering of the Company or its Affiliates, Employee hereby grants to Company and its Affiliates a non-exclusive, royalty-free, perpetual and irrevocable, worldwide right to make, use, sell, import, reproduce, distribute, modify, display, perform and sublicense such Prior Invention for the purpose of developing, manufacturing, marketing, selling, supporting, and distributing products, services, and other offerings of the Company and/or its Affiliates worldwide either directly or through multiple tiers of distribution.

(f) Assistance. Employee agrees to take all actions requested by the Company and to otherwise cooperate with and assist the Company or its designee as necessary to obtain, perfect and enforce the Company’s or its designees rights in the Employment Inventions, including any proprietary rights relating thereto, in any and all countries, including the disclosure to the Company or its designee of all pertinent information and data with respect thereto, the execution of applications, specifications, oaths, assignments, recordations, and other instruments (collectively, “Instruments”) which the Company or its designee will deem necessary in order to apply for, obtain, perfect, maintain, enforce, license or transfer such rights and in order to assign and convey to the Company, its successors, assigns and designees the sole and exclusive right, title and interest in and to the Employment Inventions, including any proprietary rights relating thereto. Employee further agrees that his obligation to cooperate with the Company and, if applicable, its successors, assigns and designees, and to execute Instruments as described in this section will continue after the termination of Employee’s employment with the Company for any reason and that the Company will compensate Employee at a reasonable rate for the time actually spent by Employee at the Company’s request with respect to such cooperation after the termination of Employee’s employment. Employee hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Employee’s agent and attorney in fact, to act for and in Employee’s behalf to execute and file any Instruments and to do all other lawfully permitted acts to further the application for, registration, prosecution, perfection, issuance, maintenance or transfer of patents, copyrights, and other proprietary rights with the same legal force and effect as if originally executed by Employee, which designation the Company will exercise if the Company is unable because of Employee’s mental or physical incapacity, unavailability, or other reason to secure Employee’s signature on any instrument as described in this Section 6. Employee hereby waives and irrevocably assigns to the Company any and all claims which Employee now or hereafter has for infringement of any and all proprietary rights assigned to the Company under this Agreement.

7. NON-COMPETE AND NON-SOLICITATION

(a) Non-Compete and Non-Solicitation. The Employee agrees that, by virtue of the Employee’s senior position with the Company and involvement in the strategic marketing plans for the products and technologies of the Company and its Affiliates, the Employee possesses and will possess strategic sensitive information concerning the business of the Company and its Affiliates.

To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Employee and the Company of the applicable provision without violating the provisions of Section 409A.

(b) Separation from Service. Notwithstanding anything in this Agreement to the contrary, any compensation or benefits payable under this Agreement that constitutes “nonqualified deferred compensation” (“Deferred Compensation”) within the meaning of Section 409A, and which is designated under this Agreement as payable upon Employee’s termination of employment will be payable only upon Employee’s “separation from service” with the Company within the meaning of Section 1.409A-1(h) of the Department of Treasury Regulations (a “Separation from Service”) and, except as provided under Section 10(c) of this Agreement, any such compensation or benefits will not be paid, or, in the case of installments, will not commence payment, until the sixtieth (60th) day following Employee’s Separation from Service. Any installment payments that would have been made to Employee during the sixty (60) day period immediately following Employee’s Separation from Service but for the preceding sentence will be paid to Employee on the sixtieth (60th) day following Employee’s Separation from Service and the remaining payments will be made as provided in this Agreement.

(c) Specified Employee. Notwithstanding any provision herein to the contrary, if Employee is deemed by the Company at the time of Employee’s Separation from Service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i), to the extent delayed commencement of any portion of the benefits to which Employee is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i), such portion of Employee’s benefits will not be provided to Employee prior to the earlier of (i) the expiration of the six-month period measured from the date of Employee’s Separation from Service with the Company or (ii) the date of Employee’s death. Upon the first business day following the expiration of the applicable Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to the preceding sentence will be paid in a lump sum to Employee (or Employee’s estate or beneficiaries), and any remaining payments due to Employee under this Agreement will be paid as otherwise provided herein.

(d) Expense Reimbursements. To the extent that any reimbursement of expenses or in-kind benefits under this Agreement are subject to the provisions of Section 409A of the Code, any such reimbursements or benefits payable to Employee will be paid to Employee no later than December 31 of the year following the year in which the expense was incurred, the amount of expenses reimbursed in one year will not affect the amount eligible for reimbursement in any subsequent year, and Employee’s right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit. The amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other year.

(e) Installments. Employee’s right to receive any installment payments under this Agreement, including without limitation any continuation salary payments that are payable on Company payroll dates, will be treated as a right to receive a series of separate payments and, accordingly, each such installment payment will at all times be considered a separate and distinct payment as permitted under Treasury Regulation Section 1.409A-2(b)(2)(iii).

11. PARACHUTE PAYMENTS.

(a) Best Pay. Any provision of this Agreement to the contrary notwithstanding, if any payment or benefit Employee would receive from the Company pursuant to this Agreement or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Reduced Amount (as defined below). The “Reduced Amount” will be either (l) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (2) the entire Payment, whichever amount after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes), results in Employee’s receipt, on an after-tax basis, of the greatest amount of the Payment. If a reduction in the Payment is to be made so that the Payment equals the Reduced Amount, (x) the Payment will be paid only to the extent permitted under the Reduced Amount alternative, and Employee will have no rights to any additional payments and/or benefits constituting the Payment, and (y) reduction in payments and/or benefits will occur in the following order: (1) reduction of cash payments; (2) cancellation of accelerated vesting of equity awards other than stock options; (3) cancellation of accelerated vesting of stock options; and (4) reduction of other benefits paid to Employee. In the event that acceleration of vesting of equity award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of Employee’s equity awards.

(b) Accounting Firm. The accounting firm engaged by the Company for general tax purposes as of the day prior to the transaction triggering the Payments will perform the calculations set forth in Section 11(a) above. If the firm so engaged by the Company is serving as accountant or auditor for the acquiring company, the Company will appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company will bear all expenses with respect to the determinations by such firm required to be made hereunder. The accounting firm engaged to make the determinations hereunder will provide its calculations, together with detailed supporting documentation, to the Company within fifteen (15) days before the consummation of a transaction triggering the Payments (if requested at that time by the Company) or such other time as requested by the Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it will furnish the Company with documentation reasonably acceptable to the Company that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder will be final, binding and conclusive upon the Company and the Employee.

12. GENERAL PROVISIONS.

(a) Severability/Enforcement.

(i) It is the desire and intent of the parties hereto that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement will be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, will be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it will, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Without limiting the generality of the preceding sentence, if at the time of enforcement of Section 5, 6 or 7 of this Agreement, a court holds that the restrictions stated therein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances will be substituted for the stated period, scope or area and that the failure of all or any of such provisions to be enforceable will not impair or affect the obligations of the Company to pay compensation or severance obligations under this Agreement.

(ii) Because the Employee’s services are unique and because the Employee has access to Proprietary Information and intellectual property and records of the Company and its Affiliates, the parties hereto agree that money damages would be an inadequate remedy for any breach of this Agreement by the Employee. Therefore, in the event of a breach or threatened breach of this Agreement, the Company or its successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security).

(iii) In addition to the foregoing, and not in any way in limitation thereof, or in limitation of any right or remedy otherwise available to the Company, if the Employee violates any provision of Section 5, 6 or 7, any severance payments then or thereafter due from the Company to the Employee may be terminated forthwith and upon such election by the Company, the Company’s obligation to pay and the Employee’s right to receive such severance payments will terminate and be of no further force or effect. The Employee’s obligations under Sections 5, 6 or 7 of this Agreement will not be limited or affected by, and such provisions will remain in full force and effect notwithstanding the termination of any severance payments by the Company in accordance with this Section 12(a)(iii). The exercise of the right to terminate such payments will not be deemed to be an election of remedies by the Company and will not in any manner modify, limit or preclude the Company from exercising any other rights or seeking any other remedies available to it at law or in equity.

(iv) Arbitration. To ensure the timely and economical resolution of disputes that arise in connection with this Agreement, Employee and the Company agree that any and all disputes, claims, or causes of action arising from or relating to the enforcement, breach, performance or interpretation of this Agreement, Employee’s employment, or the termination of Employee’s employment, will be resolved to the fullest extent permitted by law by final, binding and confidential arbitration, by a single arbitrator, in San Jose, California conducted by Judicial Arbitration and Mediation Services, Inc. (“JAMS”) under the applicable JAMS employment arbitration rules. By agreeing to this arbitration procedure, both Employee and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding. The arbitrator will: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (ii) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award. The arbitrator will be authorized to award any or all remedies that Employee or the Company would be entitled to seek in a court of law. The Company will pay all arbitration fees (including both administrative fees and fees and out of pocket costs charged by the arbitrator) in excess of the amount of initial court filing fees that would be incurred by Employee if the dispute were decided in a court of law. Nothing in this Agreement is intended to prevent either Employee or the Company from obtaining injunctive relief in court if necessary to prevent irreparable harm pending the conclusion of any such arbitration. Notwithstanding the foregoing, Employee and the Company each have the right to resolve any issue or dispute over intellectual property rights by Court action instead of arbitration.

(b) LIABILITY. IN NO EVENT WILL THE COMPANY, ITS AFFILIATES, THE BOARD OF DIRECTORS OF THE COMPANY OR ITS AFFILIATES, OR THE EMPLOYEE BE LIABLE FOR PUNITIVE, INDIRECT, SPECIAL, OR CONSEQUENTIAL DAMAGES OF ANY KIND ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT.

(c) Complete Agreement. This Agreement, those documents expressly referred to herein and that separate letter agreement between the Company and the Employee dated of event date with respect to certain events following a Change of Control of QLT Inc.(as defined and described therein) (the “Change of Control Agreement”) , embody the complete agreement and understanding among the parties and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way. To the extent that there is any conflict between the provisions of this Agreement, the Change of Control Agreement and any Stock Option Agreements, between the Company or QLT Inc. and the Employee, the following provisions will apply:

(d) Survival. The representations, warranties, covenants and agreements made herein will, as applicable, survive any termination of this Agreement in accordance with their respective terms, provided that Sections 4, 5, 6, 7, 9, 10, 11 and 12 will survive termination of this Agreement.

(e) Successors and Assigns. Except as otherwise provided herein, this Agreement will bind and inure to the benefit of and be enforceable by the Employee and the Company and their respective successors, assigns, heirs, representatives and estate; provided, however, that the rights and obligations of the Employee under this Agreement will not be assigned without the prior written consent of the Company. The Company may assign this Agreement and the rights and obligations of the Employee under this Agreement to an Affiliate of the Company with the prior written consent of the Employee.

(f) Governing Law. This Agreement will be governed by and construed in accordance with the domestic laws of the State of California without giving effect to any choice of law or conflicting provision or rule that would cause the laws of any jurisdiction other than the State of California to be applied.

(g) Amendment and Waiver. The provisions of this Agreement may be amended and waived by mutual agreement of the parties only by a written instrument executed by the Company and Employee which makes express reference to this Agreement and no course of conduct or failure or delay in enforcing the provisions of this Agreement will affect the validity, binding effect or enforceability of this Agreement or any provision hereof.

(h) Headings. The section headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation of this Agreement.

(i) Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original and all of which together will constitute one and the same instrument.

(j) Construction. The parties participated jointly in the negotiation and drafting of this Agreement and the language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent. If an ambiguity or question of intent or interpretation arises, then this Agreement will accordingly be construed as drafted jointly by the parties to this Agreement, and no presumption or burden of proof will arise favoring or disfavoring any party to this Agreement by virtue of the authorship of any of the provisions of this Agreement.

IN WITNESS WHEREOF, the parties hereto have executed this Employment Agreement as of the date first written above.

As of the date of this Agreement, Section 2870 of the California Labor Code is as follows:
