Restricted Stock Unit Award Grant Notice

Restricted Stock Unit Award Grant under the Company’s

2014 Equity Incentive Plan

Notwithstanding the foregoing, in the event of a Change of Control in which the Restricted Stock Unit Award is not being assumed or substituted as provided in Paragraph 23(d) of the Plan, the vesting of the Restricted Stock Unit Award shall accelerate such that the Restricted Stock Unit Award shall become fully vested and exercisable, effective as of immediately prior to the consummation of the Corporate Transaction that constitutes a Change of Control.

In the event (i) of a Change of Control, and (ii) the Restricted Stock Unit Award remains outstanding after such event, if the Participant is involuntarily terminated by the Company, an Affiliate or any successor corporation without Cause (not including death or disability) at the time of, or within one (1) year following the Change of Control, then the Restricted Stock Unit Award shall fully accelerate at the effective date of termination of the Participant.

Change of Control means (1) a sale of all or substantially all of the Company’s assets, or (2) any merger, consolidation or other business combination transaction of the Company with or into another corporation, entity or person, other than a transaction in which the holders of at least a majority of the shares of voting capital stock of the Company outstanding immediately prior to such transaction continue to hold (either by such shares remaining outstanding or by their being converted into shares of voting capital stock of the surviving entity) a majority of the total voting power represented by the shares of voting capital stock of the Company (or the surviving entity) outstanding immediately after such transaction, or (3) the direct or indirect acquisition (including by way of a tender or exchange offer) by any person, or persons acting as a group, of beneficial ownership or a right to acquire beneficial ownership of shares representing a majority of the voting power of the then outstanding shares of capital stock of the Company. Notwithstanding the foregoing, a Change of Control shall not be deemed to occur (A) on account of the acquisition of shares of voting capital stock by any institutional investor or any affiliate thereof or any other person, or persons acting as a group, that acquires the Company’s shares of voting capital stock in a transaction or series of related transactions that are primarily a private

financing transaction for the Company or (B) solely because the level of ownership held by any institutional investor or any affiliate thereof or any other person, or persons acting as a group (the “Subject Person”), exceeds the designated percentage threshold of the outstanding shares of voting capital stock as a result of a repurchase or other acquisition of shares of voting capital stock by the Company reducing the number of shares outstanding, provided that if a Change of Control would occur (but for the operating of this sentence) as a result of the acquisition of shares of voting capital stock by the Company, and after such share acquisition, the Subject Person becomes the owner of any additional shares of voting capital stock that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding shares of voting capital stock owned by such Subject Person over the designated percentage threshold, then a Change of Control shall be deemed to occur.

The Company and the Participant acknowledge receipt of this Restricted Stock Unit Award Grant Notice and agree to the terms of the Restricted Stock Unit Agreement attached hereto and incorporated by reference herein, the Company’s 2014 Equity Incentive Plan and the terms of this Restricted Stock Unit Award as set forth above.

SYNAGEVA BIOPHARMA CORP.

RESTRICTED STOCK UNIT AGREEMENT -

INCORPORATED TERMS AND CONDITIONS

AGREEMENT made as of the date of grant set forth in the Restricted Stock Unit Award Grant Notice between Synageva BioPharma Corp. (the “Company”), a Delaware corporation, and the individual whose name appears on the Restricted Stock Unit Award Grant Notice (the “Participant”).

WHEREAS, the Company has adopted the 2014 Equity Incentive Plan (the “Plan”), to promote the interests of the Company by providing an incentive for employees, directors and Consultants of the Company and its Affiliates;

WHEREAS, pursuant to the provisions of the Plan, the Company desires to grant to the Participant restricted stock units (“RSUs”) related to the Company’s common stock, $0.001 par value per share (“Common Stock”), in accordance with the provisions of the Plan, all on the terms and conditions hereinafter set forth; and

WHEREAS, the Company and the Participant understand and agree that any terms used and not defined herein have the meanings ascribed to such terms in the Plan.

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Grant of Award. The Company hereby grants to the Participant the number of RSUs set forth in the Restricted Stock Unit Award Grant Notice (the “Award”) which represents a contingent entitlement of the Participant to receive shares of Common Stock, on the terms and conditions and subject to all the limitations set forth herein and in the Plan, which is incorporated herein by reference. The Participant acknowledges receipt of a copy of the Plan.

2. Vesting of Award.

(a) Subject to the terms and conditions set forth in this Agreement and the Plan, the Award granted hereby shall vest as set forth in the Restricted Stock Unit Award Grant Notice and is subject to the other terms and conditions of this Agreement and the Plan. On each vesting date set forth in the Restricted Stock Unit Award Grant Notice, the Participant shall be entitled to receive such number of shares of Common Stock equivalent to the number of RSUs set forth opposite such vesting date provided that the Participant is employed or providing service to the Company or an Affiliate on such vesting date. Such shares of Common Stock shall thereafter be delivered by the Company to the Participant within five days of the applicable vesting date and in accordance with this Agreement and the Plan. The purchase price is $0.001 per share payable if and when shares of Common Stock are issued by the Company, which payment will be made by the Company on behalf of the Participant as compensation for the Participant’s prior service to the Company and which amount will be reported as income on the Participant’s W-2 (or other applicable form) in the year of payment.

(b) Except as otherwise set forth in this Agreement, if the Participant ceases to be employed or providing services for any reason by the Company or by an Affiliate (the “Termination”) prior to a vesting date set forth in the Restricted Stock Unit Award Grant Notice, then as of the date on which the Participant’s employment or service terminates, all unvested RSUs shall immediately be forfeited to the Company and this Agreement shall terminate and be of no further force or effect.

3. Prohibitions on Transfer and Sale. This Award (including any additional RSUs received by the Participant as a result of stock dividends, stock splits or any other similar transaction affecting the Company’s securities without receipt of consideration) shall not be transferable by the Participant otherwise than (i) by will or by the laws of descent and distribution, or (ii) pursuant to a qualified domestic relations order as defined by the Internal Revenue Code or Title I of the Employee Retirement Income Security Act or the rules thereunder. Except as provided in the previous sentence, the shares of Common Stock to be issued pursuant to this Agreement shall be issued, during the Participant’s lifetime, only to the Participant (or, in the event of legal incapacity or incompetence, to the Participant’s guardian or representative). This Award shall not be assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition of this Award or of any rights granted hereunder contrary to the provisions of this Section 3, or the levy of any attachment or similar process upon this Award shall be null and void.

4. Forfeiture.

This Award is subject to forfeiture, termination and rescission, and the Participant is obligated to return to the Company the value received with respect to the Shares delivered under upon vesting of the RSUs, and any gain realized on a subsequent sale or disposition of Shares), (a) upon or in connection with (i) a breach by the Participant of a non-competition, non-solicitation, confidentiality or similar covenant or agreement with the Company or an Affiliate; or (ii) an overpayment to the Participant of incentive compensation due to inaccurate financial data; (b) in accordance with Company policy relating to the recovery of erroneously-paid incentive compensation, as such policy may be amended and in effect from time to time; or (c) as otherwise required by law or applicable stock exchange listing standards, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act. By accepting this Award, the Participant hereby agrees to return the full amount required under this Section 4 at such time and in such manner as the Administrator shall determine in its sole discretion and consistent with applicable law. Neither the Administrator nor the Company will be responsible for any adverse tax or other consequences to the Participant that may arise in connection with this Section 4.

5. Adjustments. The Plan contains provisions covering the treatment of RSUs and shares of Common Stock in a number of contingencies such as stock splits. Provisions in the Plan for adjustment with respect to this Award and the related provisions with respect to successors to the business of the Company are hereby made applicable hereunder and are incorporated herein by reference.

6. Securities Law Compliance. The Participant specifically acknowledges and agrees that any sales of shares of Common Stock shall be made in accordance with the requirements of the Securities Act of 1933, as amended. The Company currently has an effective registration statement on file with the Securities and Exchange Commission with respect to the Common Stock to be granted hereunder. The Company intends to maintain this registration statement but has no obligation to do so. If the registration statement ceases to be effective for any reason or there is a restriction under foreign law, you will not be able to transfer or sell any of the shares of Common Stock issued to you pursuant to this Agreement unless exemptions from registration or filings under applicable securities laws are available. The Company shall not be obligated to either issue the Common Stock or permit the resale of any shares of Common Stock if such issuance or resale would violate any applicable securities law, rule or regulation.

7. Rights as a Stockholder. The Participant shall have no right as a stockholder, including voting and dividend rights, with respect to the RSUs subject to this Agreement.

8. Incorporation of the Plan. The Participant specifically understands and agrees that the RSUs and the shares of Common Stock to be issued under the Plan will be issued to the Participant pursuant to the Plan, a copy of which Plan the Participant acknowledges he or she has read and understands and by which Plan he or she agrees to be bound. The provisions of the Plan are incorporated herein by reference.

9. Tax Liability of the Participant and Payment of Taxes. The Participant acknowledges and agrees that any income or other taxes due from the Participant with respect to this Award or the shares of Common Stock to be issued pursuant to this Agreement or otherwise sold shall be the Participant’s responsibility. Without limiting the foregoing, the Participant agrees that if under applicable law the Participant will owe taxes at each vesting date on the portion of the Award then vested the Company shall be entitled to immediate payment from the Participant of the amount of any tax required to be withheld by the Company. Any taxes or other amounts required to be withheld by the Company by applicable law or regulation shall be paid, at the option of the Company as follows:

(a) through reducing the number of shares of Common Stock entitled to be issued to the Participant on the applicable vesting date in an amount equal to the statutory minimum of the Participant’s total tax and other withholding obligations due and payable by the Company. Fractional shares will not be retained to satisfy any portion of the Company’s withholding obligation. Accordingly, the Participant agrees that in the event that the amount of withholding required would result in a fraction of a share being owed, that amount will be satisfied by withholding the fractional amount from the Participant’s paycheck;

(b) requiring the Participant to deposit with the Company an amount of cash equal to the amount determined by the Company to be required to be withheld with respect to the statutory minimum amount of the Participant’s total tax and other withholding obligations due and payable by the Company or otherwise withholding from the Participant’s paycheck an amount equal to such amounts due and payable by the Company; or

(c) if the Company believes that the sale of shares can be made in compliance with applicable securities laws, authorizing, at a time when the Participant is not in possession of material nonpublic information, the sale by the Participant on the applicable vesting date of such number of shares of Common Stock as the Company instructs a registered broker to sell to satisfy the Company’s withholding obligation, after deduction of the broker’s commission, and the broker shall be required to remit to the Company the cash necessary in order for the Company to satisfy its withholding obligation. To the extent the proceeds of such sale exceed the Company’s withholding obligation the Company agrees to pay such excess cash to the Participant as soon as practicable. In addition, if such sale is not sufficient to pay the Company’s withholding obligation the Participant agrees to pay to the Company as soon as practicable, including through additional payroll withholding, the amount of any withholding obligation that is not satisfied by the sale of shares of Common Stock. The Participant agrees to hold the Company and the broker harmless from all costs, damages or expenses relating to any such sale. The Participant acknowledges that the Company and the broker are under no obligation to arrange for such sale at any particular price. In connection with such sale of shares of Common Stock, the Participant shall execute any such documents requested by the broker in order to

3

effectuate the sale of shares of Common Stock and payment of the withholding obligation to the Company. The Participant acknowledges that this paragraph is intended to comply with Section 10b5-1(c)(1(i)(B) under the Exchange Act.

The Company shall not deliver any shares of Common Stock to the Participant until it is satisfied that all required withholdings have been made.

10. Participant Acknowledgements and Authorizations.
