6.3 Reasonableness of Non-competition and Non-solicitation Obligations. The Employee confirms that the obligations in Sections 6.1 and 6.2 are fair and reasonable given that, among other reasons:

(a) the sustained contact the Employee will have with the clients of the Company will expose the Employee to the Confidential Information regarding the particular requirements of these clients and the Company’s unique methods of satisfying the needs of these clients, all of which the Employee agrees not to act upon to the detriment of the Company; and/or

(b) the Employee will be performing important development work on the products or services owned, developed or marketed by the Company;

and the Employee agrees that the obligations in Sections 6.1 and 6.2, together with the Employee’s other obligations under this Agreement, are reasonably necessary for the protection of the Company’s proprietary interests and that given the Employee’s general knowledge and experience they would not prevent the Employee from being gainfully employed if the employment relationship between the Employee and the Company were to end. The Employee further confirms that the geographic scope

Zymeworks-Confidential Page 10-63

of the obligation in Section 6.2 is reasonable given the nature of the market for the products and business of the Company. The Employee also agrees that the obligations in Sections 6.1 and 6.2 are in addition to the confidentiality and non-disclosure obligations provided for in this Agreement and acknowledges that the Company would not have entered into this Agreement but for the protections provided to the Company by all of the aforementioned obligations.

6.4 Conflict of Interest. The Employee recognizes that the Employee is employed by the Company in a position of responsibility and trust and agrees that during the Employee’s employment with the Company, the Employee will not engage in any activity or otherwise put the Employee in a position which conflicts with the Company’s interests. Without limiting this general statement, the Employee agrees that during the Employee’s employment with the Company, the Employee will not knowingly lend money to, guarantee the debts or obligations of or permit the name of the Employee or any part thereof to be used or employed by any corporation or firm which directly or indirectly is engaged in or concerned with or interested in any Business in competition with the Business of the Company unless the Employee receives prior written authorization from the Company.

6.5 Acknowledgments. The Employee acknowledges that as of the date of this Agreement:

(a) a breach of this Agreement would cause the Company irreparable harm and as a result the Employee consents to the issuance of an injunction or other appropriate remedy required to enforce the covenants contained herein; and

(b) in the event the Employee breaches any covenant contained herein, the one (1) year periods provided for in Sections 6.1 and 6.2 will be extended for a period of six (6) months from the date any such breach is cured. In the event it is necessary for the Company to retain legal counsel to enforce any of the terms and conditions of this Agreement, the Employee will pay the Company’s reasonable legal fees, court costs and other related expenses so long as the Company prevails in substantial and material part. In the event the Company is unsuccessful, the Company will pay the Employee’s reasonable legal fees, court costs and other related expenses.

ARTICLE 7 – ENFORCEMENT

7.1 Application to the British Columbia Supreme Court or the Federal Court of Canada. In the event of a breach or threatened breach by the Employee of any of the provisions of Article 5 or Article 6, the Company will be entitled to injunctive relief restraining the Employee from breaching such provisions, as set forth in this Agreement. Nothing in this Agreement precludes the Company from obtaining, protecting or enforcing its intellectual property rights, or enforcing the Employee’s fiduciary, non-competition, non-solicitation, confidentiality or any other post-employment obligations in a court of competent jurisdiction, or from pursuing any other remedy available to it for such breach or threatened breach, including the recovery of damages from the Employee.

Zymeworks-Confidential Page 11-63

7.2 Severability and Limitation. All agreements and covenants contained herein are severable and, in the event any of them will be held to be invalid by any competent court, this Agreement will be interpreted as if such invalid agreements or covenants were not contained herein. Should any court or other legally constituted authority determine that for any such agreement or covenant to be effective that it must be modified to limit its duration or scope, the parties hereto will consider such agreement or covenant to be amended or modified with respect to duration and scope so as to comply with the orders of any such court or other legally constituted authority or to be enforceable under the laws of the Province of British Columbia, and as to all other portions of such agreement or covenants they will remain in full force and effect as originally written.

RE: Amendment to Employment Agreement and increase in holiday entitlement

On behalf of the senior management team and board of Directors of Zymeworks Inc., I’m pleased to present this amendment to your vacation allotment which would increase your annual vacation days in 2008 from fifteen days to twenty. Additionally, one workweek of unused vacation, starting in 2008, may be carried forward to the subsequent calendar year without penalty.

The leadership and vision of our team leads such as yourself are critical to our ongoing success. So again let me thank you for your time and dedication to the Company, and your ongoing commitment to making Zymeworks a world leader in computational biotechnology.

The EMPLOYMENT AGREEMENT (the “Agreement”), made effective as of the 25th day of January 2007, BETWEEN NEIL AMIR KLOMPAS (the “Employee”) and ZYMEWORKS INC. (collectively the “parties”) will be amended to read as follows:

3.5 Vacation. The Employee will be eligible for twenty (20) days’ paid vacation per calendar year, earned pro rata at a rate of 1.66 days per completed month of service. Five (5) days of vacation time not taken during the year in which it is earned may be carried forward into the subsequent year without the written pre-approval of Management. Vacation time exceeding five (5) days not taken during the year in which it is earned may not be carried forward into the subsequent year without written pre-approval of Management. Upon termination, vacation not taken in the calendar year will be paid out according to the Employee’s annual salary at the time in which the vacation was earned, pro rated to the number of vacation days’ not taken.

IN WITNESS WHEREOF the parties have executed this amendment to the Agreement as of October 23, 2007.
