 NOW
THEREFORE, the Company and the Buyers hereby agree as follows: 
 1. PURCHASE OF PREFERRED STOCK. 

Subject to the terms and conditions set forth in this Agreement, the Company has the right to sell to the Buyers, and the Buyers or their
designees or assignees have the obligation to purchase from the Company, Purchase Shares as follows: 
 (a) Initial Purchase. On the
later of (i) the fifth Business Day following the date of this Agreement and (ii) the date each of the conditions set forth in Sections 6 and 7(a) below is satisfied, the Buyers shall purchase from the Company a number of
Purchase Shares equal to (A) One Hundred Million Dollars ($100,000,000) divided by (B) the Initial Purchase Price, and upon receipt of such Purchase Shares shall pay to the Company as the purchase price therefor, via wire transfer,
One Hundred Million Dollars ($100,000,000) less an amount equal to the Initial Commitment Fee and the Applicable Expense Amount (such purchase the “Initial Purchase” and such Purchase Shares are referred to herein as
“Initial Purchase Shares”). The date of the Initial Purchase is referred to as the “Commencement Date.” Upon issuance and payment therefor as provided herein, such Initial Purchase Shares shall be validly issued,
fully paid and non-assessable. 
 (b) VWAP Purchases. At any time during the Facility Term,
other than the 90-day period following the Commencement Date, and provided the Registration Statement is continuously effective and the conditions as set forth Section 7(b) below have
been satisfied, with ten Business Days’ prior written notice, the Company shall also have the right but not the obligation to direct the Buyers by the Company’s delivery to the Buyers of a VWAP Purchase Notice from time to time, and the
Buyers or their designees or assignees thereupon shall have the obligation, to buy the amount of Purchase Shares set forth 

 in the VWAP Purchase Notice on the VWAP Purchase Date (each such purchase, a “VWAP Purchase”) at
the VWAP Purchase Price less the Applicable Expense Amount, with the amount of Purchase Shares to be purchased by each Buyer or their designees or assignees. The Company may deliver additional VWAP Purchase Notices to the Buyers from time to time so
long as the most recent purchase has been completed and provided the Registration Statement is continuously effective and the conditions as set forth Section 7(b) below have been satisfied. On the date of the first VWAP
Purchase, the VWAP Purchase Price will be reduced by an amount equal to the Access Fee. 
 (c) Payment for Purchase Shares. For each
VWAP Purchase, the Buyers or their designees or assignees shall pay to the Company an amount equal to the VWAP Purchase Amount less the Applicable Expense Amount as full payment for such Purchase Shares via wire transfer of immediately available
funds on the VWAP Purchase Date in lawful money of the United States of America to such account as the Company may from time to time designate by written notice in accordance with the provisions of this Agreement. Whenever any amount expressed to be
due by the terms of this Agreement is due on any day that is not a Business Day, the same shall instead be due on the next succeeding day that is a Business Day. 

(d) Records of Purchases. The Buyers and the Company shall each maintain records showing the remaining Available Amount at any given
time and the dates and VWAP Purchase Amounts for each purchase, or shall use such other method reasonably satisfactory to the Buyers and the Company to reconcile the remaining Available Amount. 

(e) Taxes. The Company shall pay any and all transfer, stamp or similar taxes that may be payable with respect to the issuance and
delivery of any shares of Preferred Stock to the Buyer made under this Agreement. 
 (f) Compliance with Principal Market Rules.
Notwithstanding anything in this Agreement to the contrary, the total number of shares of Preferred Stock that may be issued under this Agreement shall not exceed such number of shares of Preferred Stock that are convertible into an aggregate of
13,561,804 shares of Common Stock (the “Exchange Cap”), which equals 19.99% of the Company’s outstanding shares of Common Stock as of the date hereof, unless stockholder approval is obtained to issue more than such number of
shares of Common Stock issuable upon conversion of the Preferred Stock. The Exchange Cap shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock
split or other similar transaction. The foregoing limitation shall not apply, regardless of whether stockholder approval has been obtained, if at any time the Exchange Cap is reached and at all times thereafter the average price paid for all
Preferred Shares issued under this Agreement is equal to or greater than $129.50 (the “Minimum Price”), a price equal to ten times the consolidated closing bid price of the Common Stock on the Business Day prior to the date hereof
(in such circumstance, for purposes of the Principal Market, the transaction contemplated hereby would not be “below market” and the Exchange Cap would not apply). The Minimum Price shall be appropriately adjusted for any reorganization,
recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction. Notwithstanding anything to the contrary in this Agreement or otherwise, the Company shall not be required or
permitted to issue, and the Buyer shall not be required to purchase, any Purchase Shares under this Agreement if such issuance would breach the Company’s obligations under the rules or regulations of the Principal Market. The Company may, in
its sole discretion, determine whether to obtain stockholder approval to issue more than 19.99% of its outstanding shares of Common Stock upon the conversion of the Purchase Shares if such issuance would require stockholder approval under the rules
or regulations of the Principal Market. Notwithstanding anything to the contrary contained herein, no Buyer shall be obligated to purchase any Preferred Stock unless such shares of Preferred Stock are fully convertible at the time of purchase except
as such conversion may be limited by any beneficial ownership limitations agreed to or imposed by the Buyers. 

  
 -2- 

 (g) Beneficial Ownership Limitation. Notwithstanding anything in this Agreement to the
contrary, the Company shall not issue, and the Buyers shall not purchase (or be obligated to purchase) any shares of Preferred Stock under this Agreement, if the shares of Common Stock issuable upon conversion of such Preferred Stock proposed to be
issued and sold, when aggregated with all other shares of Common Stock then owned beneficially (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder) by the
Buyers and their Affiliates would result in the beneficial ownership by the Buyers and their Affiliates of more than 19.99% of the outstanding shares of Common Stock or voting power of the Company, unless such issuance has been approved by the
Principal Market or received the required stockholder approval under the rules or regulations of the Principal Market. 
 2. BUYERS’
REPRESENTATIONS AND WARRANTIES. 
 Each Buyer, severally and not jointly, represents and warrants to the Company that as of the date
hereof, as of the Commencement Date and as of each VWAP Purchase Date:

Agreement and acquiring the Purchase Shares, the Warrant, the Preferred Stock issuable upon the exercise of the Warrant (and Common Stock issuable upon the conversion of such Preferred Stock) and the Underlying Shares (collectively, the

receive answers from the officers of the Company concerning the financial condition and business of the Company and other matters related to an investment in the Securities. Neither such inquiries nor any other due diligence investigations conducted
by the Buyer or its representatives shall modify, amend or affect the Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below. The Buyer has sought such accounting, legal
and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities. 

(d) No Governmental Review. The Buyer understands that no United States federal or state agency or any other government or governmental

the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary,

(ii) a material adverse effect on the results of operations, assets, business, prospects or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company’s
ability to perform in any material respect on a timely basis its obligations under any Transaction Document (any of (i), (ii) or (iii), a “Material Adverse Effect”) and no proceeding has been instituted in any such jurisdiction
revoking, limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification. 
 (b) Authorization;
Due Execution. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations hereunder and
thereunder including, without limitation, the issuance of the Purchase Shares and the Underlying Shares. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated
hereby and thereby have been duly authorized by all necessary action on the part of the Company and no further action is required by the Company, the Board of Directors or the Company’s stockholders in connection therewith other than in
connection with the Required Approvals (as defined in Section 3(bb) herein). Each Transaction Document to which it is a party has been (or upon delivery will have been) duly executed by the Company and, when delivered
in accordance with the terms hereof and thereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except (i) as limited by general equitable principles and applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief

officer’s insurance in reasonable and customary coverage amounts.

 4. COVENANTS AND OTHER RIGHTS. 

(a) Listing of Common Stock. The Company shall promptly secure the listing of the Underlying Shares upon each national securities
exchange and automated quotation system that requires an application by the Company for listing, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance) and shall maintain such listing, so long as any other
shares of Common Stock shall be so listed. The Company shall use its reasonable best efforts to maintain the Common Stock’s listing on the Principal Market. Neither the Company nor any of its Subsidiaries shall take any action that would be
reasonably expected to result in the delisting or suspension of the Common Stock on the Principal Market, unless the Common Stock is immediately thereafter traded on the New York Stock Exchange, the NYSE MKT, the Nasdaq Global Select Market, the
Nasdaq Global Market, the Nasdaq Capital Market, or the OTCQB or OTCQX market places of the OTC Markets. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 4(a).

 (b) Limitation on Purchases. The Buyer agrees that beginning on the date of this Agreement and ending on the time of filing of a
Current Report on Form 8-K disclosing the terms of the Transaction Documents and the terms of the Initial Purchase (the “Form 8-K”), the Buyer and its
agents, representatives and affiliates shall not in any manner whatsoever enter into or effect, directly or indirectly, any purchase or sale of any Common Stock or derivative securities of the Common Stock or take any action designed to cause or to
result in the stabilization or manipulation of the price of any security of the Company. The Company covenants and agrees that it shall file the Form 8-K no later than prior to the commencement of trading on
the Principal Market on January 11, 2018. The Company confirms that, following the filing of the Form 8-K, it shall have disclosed in the SEC Filings all information that it believes constitutes or might
constitute material, non-public information that the Company or any other Person acting on its behalf has provided to any of the Buyers or its agents or counsel. 

(c) Public Offering Participation Rights. During the Facility Term, each Buyer shall have the right to submit to the managing
underwriter(s) in any public offering of securities by the Company a non-binding indication of interest to participate in such offering by purchasing that number of securities equal to such Buyer’s pro
rata ownership of the Company (without giving effect to any beneficial ownership or similar caps in place at the time of the public offering and assuming (without requiring) full conversion of all convertible securities held by such Buyer and its
Affiliates) at the time of such offering multiplied by the total securities being offered. If the indication of interest is delivered by a Buyer, the Company shall use its reasonable best efforts to cause the managing underwriter(s) of such offering
to offer directly to such Buyer the right to purchase at least such amount of securities in such offering. If a Buyer submits an indication of interest but (i) the managing underwriter(s) of the offering determines in its or their sole
discretion that it is not advisable to make the available securities to such Buyer or (ii) the Company determines (based on advice of legal counsel) that the offer and sale of securities to such Buyer is not permissible under federal securities
laws or any other applicable laws, rules and regulations, then the Company shall offer an equivalent number of securities to such Buyer in a concurrent private placement offering (subject to compliance with federal securities laws or any other
applicable laws, rules and regulations). Nothing in this Section 4(c) or otherwise in this Agreement shall limit the Company’s ability to conduct a public offering during the Facility Term. 

(d) Warrant. In the event a Deemed Liquidation (as defined in the Certificate of Designation) occurs within 24 months of the date of
this Agreement, the Company will issue to one or more Affiliates, designees or assignees of the Buyers as designated in writing to the Company by Redmile Group, LLC, at least five (5) Business Days prior to the Deemed Liquidation, a warrant in
the form 

  
 -14- 

 
attached hereto as Exhibit D (the “Warrant”) to purchase an aggregate of 75,000 Preferred Shares at a purchase price per share equal to the Initial Purchase Price (share
number and exercise price each subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction). 

(e) Taxes. The Company shall pay any and all transfer, stamp or similar taxes that may be payable with respect to the issuance and
delivery of any Purchase Shares to the Buyers made under this Agreement.  
 (f) Other Transactions. The Company shall not
enter into, announce or recommend to its stockholders any agreement, plan, arrangement or transaction in or of which the terms thereof would restrict, materially delay, conflict with or impair the ability or right of the Company to perform its
obligations under the Transaction Documents, including, without limitation, the obligation of the Company to deliver the Purchase Shares to the Buyers in accordance with the terms of the Transaction Documents. 

(g) Integration. From and after the date of this Agreement, neither the Company, nor any of its Affiliates will, and the Company shall
use its reasonable best efforts to ensure that no Person acting on their behalf will, directly or indirectly, make any offers or sales of any security or solicit any offers to buy any security, under circumstances that would (i) require
registration of the offer and sale by the Company to the Buyers of any of the Securities under the Securities Act, or (ii) cause this offering of the Securities by the Company to the Buyers to be integrated with other offerings of securities by
the Company in a manner that would require stockholder approval pursuant to the rules and regulations of the Principal Market on which any of the securities of the Company are listed or designated, unless in the case of this clause (ii), stockholder
approval is obtained before the closing of such subsequent transaction in accordance with the rules of such Principal Market. 
 (h)
Anti-Takeover Provisions. From and after the date of this Agreement, neither the Company nor its Board of Directors shall approve or adopt any control share acquisition, business combination, poison pill (including any distribution under a
rights agreement) or other similar anti-takeover provision (“Anti-Takeover Provisions”), that is or would reasonably be expected to become applicable to the Buyers as a result of the conversion of the Purchase Shares into shares of
Common Stock so long as any shares of Preferred Stock are outstanding unless the Company and the Board have taken all necessary action to render such Anti-Takeover Provisions inapplicable to the shares of Common Stock issuable upon conversion of the
Preferred Stock. 
 5. TRANSFER RESTRICTIONS. 

(a) Compliance with Laws. Notwithstanding any other provision of this Section 5, each Buyer covenants that the
Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Securities other than (i) pursuant to an effective registration statement,

may be sold pursuant to such rule), the Company may require such Buyer to provide to the Company an opinion of counsel selected by such Buyer and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably

applicable Securities upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”), if (i) such Securities are registered for resale under the

breach of any of the Buyers’ representations and warranties, covenants or agreements contained in this Agreement, or (B) the gross negligence, bad faith or willful misconduct of the Buyers or any other Indemnitee. To the extent that the
foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. 

(b) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted
against any person in respect of which indemnification may be sought pursuant to paragraph (a) above, such Indemnitee shall promptly notify the Company in writing; provided that the failure to notify Company shall not relieve it from any
liability that it may have under paragraph (a) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure. The Company shall have the right to participate in any
such suit, action, proceeding (including any governmental or regulatory investigation), claim or demand and, to the extent the suit, action, proceeding (including any governmental or regulatory investigation), claim or demand is brought by a third
party (a “Third-Party Claim”) and the Company so desires, so long as the Company acknowledges in writing its obligation to indemnify an Indemnitee pursuant to paragraph (a) above, the Company shall be entitled to assume the
defense of any such suit, action, proceeding, claim or demand at the Company’s expense and through counsel selected by the Company (which counsel shall be reasonably acceptable to the Indemnitee). If the Company has assumed the defense of a
Third-Party Claim in accordance with this Section 8(b), then no compromise or settlement of such Third-Party Claim may be effected by the Company without the Indemnitee’s prior written consent unless (A) such
compromise or settlement (i) includes as an unconditional term thereof the delivery by the Person(s) asserting such claim to the Indemnitee of a written unconditional release from all Indemnified Liabilities in respect of such Third-Party Claim
and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any Indemnitee, and (B) the sole relief provided for in such compromise or settlement is monetary damages which will
be paid in full by the Company. In any Third-Party Claim the defense of which has been assumed by the Company in accordance with this Section 8(b): (i) the Indemnitee shall have the right to be represented by counsel of its
own choosing at the Indemnitee’s sole cost and expense, except the Indemnitee shall be entitled to retain its own counsel at the expense of the Company if (x) the Indemnitee shall have been advised by counsel that there are one or more
legal or equitable defenses available to it that are different from or in addition to those available to the Company, and, in the reasonable judgment of the Indemnitee, counsel for the Company could not adequately represent the interests of the
Indemnitee because such interests could be in conflict with those of the Company, (y) such Third-Party Claim involves, or is reasonably likely to have a material effect on, any matter beyond the scope of the indemnification obligation of the

  
 -19- 

 
Company, or (z) the Company shall not have assumed the defense of the Third-Party Claim in a timely fashion; and (ii) the Company shall keep the Indemnitee fully informed as to the
status of such Third-Party Claim at all stages thereof, whether or not the Indemnitee is represented by its own counsel. The Company shall not be liable for any settlement of any proceeding effected without its written consent (not to be
unreasonably conditioned, withheld or delayed).

against the Company, a Custodian is appointed for the Company or for all or substantially all of its property, or the Company makes a general assignment for the benefit of its creditors, (any of which would be an Event of Default as described in
Sections 9(e), 9(f) and 9(g) hereof) this Agreement shall automatically terminate without any liability or payment to the Company without further action or notice by any Person. No such termination of this Agreement under
Section 11(k)(i) shall affect the Company’s or any of the Buyer’s obligations under this Agreement with respect to pending purchases and the Company and the Buyers shall complete their respective obligations with
respect to any pending purchases under this Agreement.

a voluntary case or any Person commences a proceeding against the Company, a Custodian is appointed for the Company or for all or substantially all of its property, or the Company makes a general assignment for the benefit of its creditors, (any of
which would be an Event of Default as described in Sections 9(e), 9(f) and 9(g) hereof) this Agreement shall automatically terminate without any liability or payment to the Company without further action or notice by any Person.
No such termination of this Agreement under this Section 11(k)(i) shall affect the Company’s or the Buyers’ obligations under this Agreement with respect to pending purchases and the Company and the Buyers shall
complete their respective obligations with respect to any pending purchases under this Agreement. 
 (ii) In the event that
the Commencement Date shall not have occurred within twenty (20) Business Days of the date of this Agreement, due to the failure to satisfy any of the conditions set forth in Sections 6 and 7(a) above with respect to the
Commencement Date, either party shall have the option to terminate this Agreement at the close of business on such date or thereafter without liability of either party to any other party; provided, however, that the right to terminate this Agreement
under this Section 11(k)(ii) shall not be available to either party if such failure to satisfy any of the conditions set forth in Sections 6 and 7 is the result of a breach of this Agreement by such party or
the failure of any representation or warranty of such party included in this Agreement to be true and correct in all material respects. 

(iii) At any time after the Commencement Date, the Company shall have the option to terminate this Agreement for any reason or
for no reason by delivering notice (a “Company Termination Notice”) to the Buyers electing to terminate this Agreement without any liability whatsoever of either party to the other party under this Agreement. The Company Termination
Notice shall not be effective until one (1) Business Day after it has been received by the Buyers. 
 (iv) This
Agreement shall automatically terminate on the date that the Company sells and the Buyers purchase the full Available Amount as provided herein, without any action or notice on the part of any party and without any liability whatsoever of any party
to any other party under this Agreement. 
 (v) This Agreement shall automatically terminate on the date that the Company
raises, in one or more financing transactions or closings after the date of this Agreement, for aggregate gross proceeds to the Company of at least $100,000,000 (whether through the issuance of debt, convertible debt or equity securities or
otherwise) during the Facility Term (excluding for this purpose any proceeds received by the Company under this Agreement). 

(vi) This Agreement shall automatically terminate on the date of any Deemed Liquidation (as defined in the Certificate of
Designation). 
 Except as set forth in Sections 11(k)(i) (in respect of an Event of Default under Sections 9(e), 9(f)
and 9(g)), 11(k)(iv) and 11(k)(v), any termination of this Agreement pursuant to this Section 11(k) shall be effected by written notice from the Company to the Buyers, or the Buyers or Redmile Group,
LLC to the Company, as the case may be, setting forth the basis for the termination hereof. The representations and warranties of the Company and the Buyers contained in Sections 2 and 3 hereof, the indemnification provisions set forth
in Section 8 hereof and the agreements and covenants set forth in Sections 4(e), 5 and 11 and this paragraph shall survive the Commencement Date and any termination of this Agreement. No
termination of this Agreement shall affect the Company’s or the Buyers’ rights or obligations (i) under the Registration Rights Agreement which shall survive any such termination in accordance with its terms or (ii) under this
Agreement with respect to pending purchases and the Company and the Buyers shall complete their respective obligations with respect to any pending purchases under this Agreement. 

  
 -27- 

 (l) No Financial Advisor, Placement Agent, Broker or Finder. The Company represents and
warrants to the Buyers that it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby. Each of the Buyers represents and warrants to the Company that it has not engaged any
financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby. Each party shall be responsible for the payment of any fees or commissions, if any, of any financial advisor, placement agent, broker or
finder engaged by such party relating to or arising out of the transactions contemplated hereby. Each party shall pay, and hold the other party harmless against, any liability, loss or expense (including, without limitation, attorneys’ fees and
out of pocket expenses) arising in connection with any such claim.

will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 

(n) Amendment and Waiver; Failure or Indulgence Not Waiver. No provision of this Agreement may be amended other than by a written
instrument signed by the Company and (i) prior to the Commencement Date, the Buyers obligated to purchase at least a majority of the Initial Purchase Shares, or (ii) after the Commencement Date, (a) the Buyers obligated to
purchase at least a majority of the Purchase Shares to be sold in a VWAP Purchase Notice, and (b) Redmile Group, LLC, but only to the extent that the Buyers obligated to purchase at least a majority of the Purchase Shares to be sold in a VWAP
Purchase Notice are not funds, accounts or entities managed by Redmile Group, LLC or any of its Affiliates; provided that no consent of the Company shall be required in order to assign or add additional Buyers to this Agreement in accordance with
Section 11(g). No provision of this Agreement may be waived other than in a written instrument signed by the party against whom enforcement of such waiver is sought. No failure or delay in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

FORM OF REGISTRATION RIGHTS AGREEMENT 

 REGISTRATION RIGHTS AGREEMENT 

REGISTRATION RIGHTS AGREEMENT (this “Agreement”), dated as of January [12], 2018, by and between Alder

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Company and the Buyers hereby agree as follows: 
 1. DEFINITIONS.

 2. REGISTRATION.

 a. Mandatory Registration. The Company shall within twenty (20) days from the Commencement Date file with the SEC a prospectus
supplement to the Shelf Registration Statement specifically relating to the Registrable Securities (the “Prospectus Supplement”). The Buyers and their counsel shall have had a reasonable opportunity to review and comment upon such
Prospectus Supplement prior to its filing with the SEC. The Buyers shall furnish all information reasonably requested by the Company for inclusion therein. The Company shall use its reasonable best efforts to keep the Shelf Registration Statement
effective pursuant to Rule 415 promulgated under the 1933 Act and available for sales of all of the Registrable Securities at all times until the earlier of (i) the date on which the Buyers shall have sold, either publicly pursuant to the
Registration Statement or pursuant to Rule 144 under the 1933 Act, all the Registrable Securities and no Available Amount remains under the Purchase Agreement, or (ii) the date five (5) years from the date of this Agreement (collectively,
the “Registration Period”). In addition, a Buyer’s rights under this Agreement shall terminate if such Buyer can sell all of its Registrable Securities under Rule 144 under the 1933 Act without restriction during any ninety
(90) day period. The Shelf Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be
stated therein, or necessary to make the statements therein, in light of the 

  
 3 

 
circumstances under which they were made, not misleading. The Company hereby represents and warrants to the Buyers that: (i) the Shelf Registration Statement is effective and available for
the resale of the Registrable Securities in accordance with Rule 430B under the 1933 Act, and (ii) the Company has not received any notice that the SEC has issued or intends to issue a stop-order with respect to the Shelf Registration Statement
or that the SEC otherwise has suspended or withdrawn the effectiveness of the Shelf Registration Statement, either temporarily or permanently, or intends or has threatened in writing to do so. 

b. Rule 424 Prospectus. The Company shall, as required by applicable securities regulations, from time to time file with the SEC,
pursuant to Rule 424 promulgated under the 1933 Act, a prospectus, including any amendments or prospectus supplements thereto, to be used in connection with sales of the Registrable Securities under the Registration Statement. The Buyers and their
counsel shall have two (2) Business Days to review and comment upon such prospectus prior to its filing with the SEC. If the Buyers have comments on such prospectus, the Buyers shall use their reasonable best efforts to provide such comments
within two (2) Business Days from the date the Buyers receive the final version of such prospectus. 
 c. Sufficient Number of Shares
Registered. In the event the number of shares registered pursuant to the Prospectus Supplement is insufficient to cover the Registrable Securities or if the Shelf Registration Statement has expired or is otherwise no longer available, the
Company shall file a new registration statement (a “New Registration Statement”), so as to cover all of such Registrable Securities as soon as reasonably practicable, but in any event not later than ten (10) Business Days after
the necessity therefor arises. The Company shall use its reasonable best efforts to have any such New Registration Statement become effective as soon as practicable following the filing thereof. 

3. RELATED OBLIGATIONS. 
 With
respect to the Registration Statement and whenever any Registrable Securities are to be registered pursuant to Sections 2(a) and (c), including on the Shelf Registration Statement or on any New Registration Statement, the Company shall use its
reasonable best efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations: 

a. The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any Registration
Statement and any Prospectus used in connection with such Registration Statement, as may be necessary to keep the Registration Statement effective at all times during the Registration Period, subject to Permitted Delays and Section 3(e) hereof
and, during such period, comply with the provisions of the 1933 Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement until such time as all of such Registrable Securities shall have
been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement. Should the Company file a post-effective amendment to the Registration Statement, the Company will
use its reasonable best efforts to have such filing declared effective by the SEC within thirty (30) consecutive Business Days following the date of filing, which such period shall be extended for an additional thirty (30) Business Days if
the Company receives a comment letter from the SEC in connection therewith. If (i) there is material non-public information regarding the Company which the Company’s Board of Directors reasonably
determines not to be in the Company’s best interest to disclose and which the Company is not otherwise required to disclose or (ii) there is a significant business opportunity (including, but not limited to, the acquisition or disposition
of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or other similar transaction) available to the Company which the Company’s Board of Directors reasonably determines not to be in the
Company’s best interest 

  
 4 

 
to disclose and which the Company would be required to disclose under a Registration Statement, then the Company may postpone or suspend filing or effectiveness of such Registration Statement or
use of the prospectus under the Registration Statement for a period not to exceed thirty (30) consecutive days, provided that the Company may not postpone or suspend its obligation under this Section 3(a) for more than sixty (60) days
in the aggregate during any twelve (12) month period (each, a “Permitted Delay”). 
 b. The Company shall submit to the
Buyers for review and comment any disclosure in the Registration Statement, and all amendments and supplements thereto (other than prospectus supplements that consist only of a copy of a filed Form 10-K, Form 10-Q or Current Report on Form 8-K or any amendment as a result of the Company’s filing of a document that is incorporated by reference into the Registration Statement),
containing information provided by the Buyers for inclusion in such document and any descriptions or disclosure regarding the Buyers, the Purchase Agreement, including the transaction contemplated thereby, or this Agreement at least two
(2) Business Days prior to their filing with the SEC, and not file any document in a form to which any of the Buyers reasonably and timely objects. Upon request of a Buyer, the Company shall provide to such Buyer all disclosure in the
Registration Statement and all amendments and supplements thereto (other than prospectus supplements that consist only of a copy of a filed Form 10-K, Form 10-Q or
Current Report on Form 8-K or any amendment as a result of the Company’s filing of a document that is incorporated by reference into a Registration Statement) at least two (2) Business Days prior to
their filing with the SEC, and not file any document in a form to which any of the Buyers reasonably and timely objects. If any of the Buyers have comments on the Registration Statement and any amendments or supplements thereto, such Buyer shall use
its reasonable best efforts to comment thereon within two (2) Business Days from the date the Buyers receive the final version thereof. The Company shall furnish to the Buyers, without charge, any correspondence from the SEC or the staff of the
SEC to the Company or its representatives relating to the Registration Statement, except if such notice and the contents thereof shall be deemed to constitute material non-public information. 

c. Upon request of any of the Buyers, the Company shall furnish to such Buyer, (i) promptly after the same is prepared and filed with the
SEC, at least one copy of the Registration Statement and any amendment(s) thereto, including all financial statements and schedules, all documents incorporated therein by reference and all exhibits, (ii) upon the effectiveness of any
amendment(s) to a Registration Statement, a copy of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as a Buyer may reasonably request) and (iii) such other
documents, including copies of any preliminary or final prospectus, as a Buyer may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Buyer. 

d. The Company shall use reasonable best efforts to (i) register and qualify, unless an exemption from registration and qualification is
available, the Registrable Securities covered by a Registration Statement under such other securities or “blue sky” laws of such jurisdictions in the United States as any of the Buyers reasonably requests, (ii) subject to Permitted
Delays, prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period,
(iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify each Buyer who
holds Registrable Securities of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any
jurisdiction in the United States or its receipt of actual notice of the initiation or threat of any proceeding for such purpose. 

  
 5 

 e. Subject to Permitted Delays, as promptly as reasonably practicable after becoming aware of
such event or facts, the Company shall notify the Buyers in writing if the Company has determined that the Prospectus included in any Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and as promptly as reasonably practical (taking into account the Company’s good
faith assessment of any adverse consequences to the Company and its stockholders of premature disclosure of such event or facts) prepare a prospectus supplement or amendment to such Registration Statement to correct such untrue statement or
omission, and, upon any Buyer’s request, deliver a copy of such prospectus supplement or amendment to such Buyer. In providing this notice to the Buyers, the Company shall not include any other information about the facts underlying the
Company’s determination and shall not in any way communicate any material nonpublic information about the Company, the Preferred Stock or the Common Stock to the Buyers. The Company shall also promptly notify the Buyers in writing (i) when
a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification of such effectiveness shall be delivered to the Buyers by
facsimile or e-mail on the same day of such effectiveness), (ii) of any request by the SEC for amendments or supplements to any Registration Statement or related prospectus or related information, and
(iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate. In no event shall the delivery of a notice under this Section 3(e), or the resulting unavailability of a
Registration Statement, without regard to its duration, for disposition of securities by the Buyers be considered a breach by the Company of its obligations under this Agreement. The preceding sentence in this Section 3(e) does not limit
whether an event of default has occurred as set forth in Section 9 of the Purchase Agreement. 
 f. The Company shall use its reasonable
best efforts to prevent the issuance of any stop order or other suspension of effectiveness of any Registration Statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at the earliest practical time and to notify the Buyers of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose. 
 g. The Company shall (i) cause all the Registrable Securities to be listed on each securities
exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange, or (ii) secure designation and quotation
of all the Registrable Securities if the Principal Market (as such term is defined in the Purchase Agreement) is an automated quotation system. The Company shall pay all fees and expenses in connection with satisfying its obligation under this
Section. 
 h. The Company shall cooperate with the Buyers to facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered pursuant to any Registration Statement and enable such certificates to be in such denominations or amounts as the Buyers may reasonably request and registered in such names as
the Buyers may request. 

  
 6 

 i. If reasonably requested by a Buyer, the Company shall (i) promptly incorporate in a
prospectus supplement or post-effective amendment to the Registration Statement such information as such Buyer believes should be included therein relating to the sale and distribution of Registrable Securities, including, without limitation,
information with respect to the number of Registrable Securities being sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities; (ii) make all required filings of such prospectus supplement
or post-effective amendment as promptly as practicable once notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration Statement (including
by means of any document incorporated therein by reference). 
 j. The Company shall use its reasonable best efforts to cause the Registrable
Securities covered by any Registration Statement to be registered with or approved by such other governmental agencies or authorities in the United States as may be necessary to consummate the disposition of such Registrable Securities. 

k. If reasonably requested by a Buyer at any time, the Company shall deliver to such Buyer a written confirmation from the Company’s
counsel of whether or not the effectiveness of such Registration Statement has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not the Registration Statement is currently effective and
available to the Company for sale of all of the Registrable Securities. 
 4. OBLIGATIONS OF THE BUYERS. 

a. Each Buyer has furnished to the Company in EXHIBIT B hereto such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable Securities held by it as reasonably requested by the Company in order to effect the registration of such Registrable Securities. The Company shall notify the Buyers in
writing of any other information the Company reasonably requires from the Buyers in connection with any Registration Statement hereunder. Each Buyer will as promptly as practicable notify the Company of any material change in the information set
forth in EXHIBIT B, other than changes in its ownership of Common Stock. 
 b. Each Buyer agrees to cooperate with the
Company as reasonably requested by the Company in connection with the preparation and filing of any amendments and supplements to any Registration Statement hereunder. 

5. EXPENSES OF REGISTRATION. 

All reasonable expenses of the Company, other than sales or brokerage commissions incurred by the Buyers and fees and disbursements of counsel
for the Buyers, incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, and fees and
disbursements of counsel for the Company, shall be paid by the Company. 
 6. INDEMNIFICATION. 

a. To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Buyer, each Person, if
any, who controls a Buyer, the members, the directors, officers, partners, employees, agents, representatives of each Buyer and each Person, if any, who controls a Buyer within the meaning of the 1933 Act or the Securities Exchange Act of 1934, as
amended (the “1934 Act”) (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement
(with the prior consent of the Company, such consent not to be unreasonably withheld) or expenses, joint or several (collectively, “Claims”), incurred in investigating, preparing or defending any

  
 7 

 
action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency or body or the SEC,
whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in the Registration Statement or any post-effective amendment thereto or in any filing made in connection
with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in the final Prospectus or the omission or alleged
omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, (iii) any violation or alleged violation by the Company of
the 1933 Act, the 1934 Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to the Registration Statement, or
(iv) any material violation by the Company of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”). The Company shall reimburse each Indemnified Person promptly as such
expenses are incurred and are due and payable, for any reasonable legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a): (A) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information about a Buyer furnished
in writing to the Company by such Buyer or such Indemnified Person expressly for use in connection with the preparation of the Registration Statement, the Prospectus or any such amendment thereof or supplement thereto, if such prospectus was timely
made available by the Company; (B) with respect to any superseded prospectus, shall not inure to the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or
to the benefit of any other Indemnified Person) if the untrue statement or omission of material fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such revised prospectus was
timely made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was promptly advised in writing not to use the incorrect prospectus prior to the use giving rise to a violation and such Indemnified
Person, notwithstanding such advice, used it; (C) shall not be available to the extent such Claim is based on a failure of a Buyer to deliver, or to cause to be delivered, the prospectus made available by the Company, if such prospectus was
theretofore made available by the Company pursuant to Section 3(c) or Section 3(e); and (D) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company,
which consent shall not be unreasonably withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the
Registrable Securities by a Buyer pursuant to Section 8. 
 b. In connection with the Registration Statement or Prospectus, each Buyer,
severally and not jointly, agrees to indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors, each of its officers who signed the Registration
Statement and each Person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act (collectively and together with an Indemnified Person, an “Indemnified Party”), against any Claim or Indemnified Damages
to which any of them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only to the extent, that such
Violation occurs in reliance upon and in conformity with written information about such Buyer set forth on EXHIBIT B hereto or updated from time to time in writing by such Buyer and furnished to the Company by such Buyer

  
 8 

 
expressly for inclusion in the Shelf Registration Statement or Prospectus or any New Registration Statement or from the failure of such Buyer to deliver or to cause to be delivered the prospectus
made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e); and, subject to Section 6(d), such Buyer will reimburse any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not
apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Buyer, which consent shall not be unreasonably withheld, conditioned or delayed; provided, further, however, that such Buyer
shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net amount of proceeds actually received by such Buyer as a result of the sale of Registrable Securities pursuant to such
registration statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by such Buyer pursuant to
Section 8. 
 c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the
commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be, and upon such notice, the
indemnifying party shall not be liable to the Indemnified Person or Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Person or Indemnified Party in connection with the defense thereof; provided, however,
that an Indemnified Person or Indemnified Party (together with all other Indemnified Persons and Indemnified Parties that may be represented without conflict by one counsel) shall have the right to retain its own counsel with the fees and expenses
to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate
due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate fully with the
indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person
which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying
party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party
shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time
of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability
to defend such action. 

  
 9 

 d. The indemnification required by this Section 6 shall be made by payments at least as
frequently as every 30 days of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred. Any person receiving a payment pursuant to this Section 6 which person is
later determined to not be entitled to such payment shall return such payment (including reimbursement of expenses) to the person making it. 

e. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law. 

7. CONTRIBUTION. 
 To the extent
any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest
extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any party who was
not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds actually received by such seller from the sale of such Registrable Securities.

 8. ASSIGNMENT OF REGISTRATION RIGHTS. 

The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Buyers holding a
majority of the Registrable Securities; provided, however, that any transaction, whether by merger, reorganization, restructuring, consolidation, financing or otherwise, whereby the Company remains the surviving entity immediately after such
transaction shall not be deemed an assignment. Any Buyer may assign its rights under this Agreement to any transferee or holder of the Registrable Securities without the prior written consent of the Company; provided that such transferee or
holder of the Registrable Securities executes and delivers an additional counterpart signature page to this Agreement and EXHIBIT A hereto shall be updated to reflect the information with respect to such transferee or
holder. 
 9. AMENDMENT OF REGISTRATION RIGHTS. 

Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively) only with the written consent of (a) the Company, (b) the Buyers holding a majority of the Registrable Securities, and (c) Redmile Group, LLC, but only to the extent that the Buyers holding a majority
of the Registrable Securities are not funds, accounts or entities managed by Redmile Group, LLC or any of its Affiliates. 
 10. ADDITIONAL
REGISTRATION STATEMENTS. 
 During the period beginning on the date hereof and ending on the last day of the Registration Period, if at any
time there is not an effective Registration Statement available for the resale of the Registrable Securities under the 1933 Act, the Company shall not file a Registration Statement or an offering statement under the 1933 Act relating to securities
that are not the Registrable Securities (other than a Registration Statement on Form S-8, or such supplements or amendments to Registration Statements that are outstanding and have been declared effective by
the SEC as of the date hereof, solely to the extent necessary to keep such registration statements effective and available).

Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any
provision of this Agreement in any other jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF

Section 2. Designation, Amount and Par Value; Assignment. 

(a) The series of preferred stock designated by this Certificate of Designation shall be designated as the Corporation’s
Class A-[•] Convertible Preferred Stock (the “Class A-[•] Preferred
Stock”) and the number of shares so designated shall be [•]. The Class A-[•] Preferred Stock shall have a par value of $0.0001 per share. 

(b) The Corporation shall register shares of the Class A-[•] Preferred Stock, upon records to be maintained
by the Corporation for that purpose (the “Class A-[•] Preferred Stock Register”), in the name of the Holders thereof
from time to time. The Corporation may deem and treat the registered Holder of shares of Class A-[•] Preferred Stock as the absolute owner thereof for the purpose of any conversion thereof and for
all other purposes. Shares of Class A-[•] Preferred Stock may be issued solely in book-entry form or, if requested by any Holder, such Holder’s shares may be issued in certificated form. The
Corporation shall register the transfer of any shares of Class A-[•] Preferred Stock in the Class A-[•] Preferred Stock Register, upon surrender of
the certificates (if applicable) evidencing such shares to be transferred, duly endorsed by the Holder thereof, to the Corporation at its address specified herein. Upon any such registration or transfer, a new certificate (or book-entry notation, if
applicable) evidencing the shares of Class A-[•] Preferred Stock so transferred shall be issued to the transferee and a new certificate (or book-entry notation, if applicable) evidencing the
remaining portion of the shares not so transferred, if any, shall be issued to the transferring Holder, in each case, within three Business Days. The provisions of this Certificate of Designation are intended to be for the benefit of all Holders
from time to time and shall be enforceable by any such Holder. 

 Section 3. Dividends. 

(a) The Holders shall be entitled to receive: 

(i) on each share of Class A-[•] Preferred Stock, dividends at a rate of 5% per annum of the Class A-[•] Original Issue Price, compounded annually from and after the Issuance Date of any such share of Class A-[•] Preferred Stock, which shall be
payable as set forth below (the “Preferred Dividends”); and 
 (ii) when, as and if declared by the Board, out of any
funds legally available therefor, dividends on shares of Class A-[•] Preferred Stock equal (on an as-if-converted-to-Common-Stock basis) to and in the same form as dividends (other than dividends in the form of Common Stock, which shall be made in accordance with Section 7(a)) actually
paid on shares of the Common Stock when, as and if such dividends (other than dividends in the form of Common Stock, which shall be made in accordance with Section 7(a)) are paid on shares of the Common Stock (the “Participating
Dividends” and, together with the Preferred Dividends, the “Dividends”). 
 (iii) Other than as set
forth in the previous sentence, no other dividends shall be paid on shares of Class A-[•] Preferred Stock. The Corporation will not declare or pay any dividends or other distributions on the Common
Stock that would require a Participating Dividend unless it concurrently therewith declares and sets aside for payment or distribution, as applicable, such Participating Dividend for all shares of
Class A-[•] Preferred Stock then outstanding. 
 (b) Preferred Dividends shall be cumulative and shall
accrue and accumulate semi-annually commencing on the Issue Date and be payable semi-annually in arrears on June 30 and December 31 of each year commencing on [June 30, 2018] (each, a “Preferred Dividend Payment
Date,” and the period from the Issuance Date to the first Preferred Dividend Payment Date and each such quarterly period thereafter being a “Preferred Dividend Period”). Participating Dividends shall be payable
as and when paid to the holders of Common Stock (each such date being a “Participating Dividend Payment Date,” and, together with each Preferred Dividend Payment Date, a “Dividend Payment Date”).
Preferred Dividends that are payable on Class A-[•] Preferred Stock in respect of any Preferred Dividend Period shall be computed on the basis of a 360-day
year consisting of twelve 30-day months. The amount of Preferred Dividends payable on Class A-[•] Preferred Stock on any date prior to the end of a Preferred
Dividend Period, and for the initial Preferred Dividend Period, shall be computed on the basis of a 360-day year consisting of twelve 30-day months, and actual days
elapsed over a 30-day month. Preferred Dividends shall accumulate whether or not in any Preferred Dividend Period there have been funds of the Corporation legally available for the payment of such Preferred
Dividends. Participating Dividends are payable on a cumulative basis once declared, whether or not there shall be funds legally available for the payment thereon. 

(c) Preferred Dividends shall, at the option of the Corporation, be paid in cash or by issuance and delivery of additional fully paid and nonassessable shares
of Class A-[•] Preferred Stock (“PIK Shares”) in lieu of the payment in cash of all or a portion of the dividend otherwise payable on any Dividend Payment Date, in the case of
PIK Shares, by issuance and delivery of an amount of PIK Shares (rounding up in the case of any resulting fractional number of PIK Shares) for each Holder equal to (i) the aggregate dollar amount of the Preferred Dividend payable to such Holder
with respect to the Class A-[•] Preferred Stock held by such Holder as of the Preferred Dividend Payment Date, divided by (ii) the Class A-[•]
Original Issue Price. Participating Dividends shall be paid when and in a manner consistent with payments of dividends in respect of the Common Stock. No later than the record date for the determination of stockholders entitled to receive any
Preferred Dividend, the Corporation will send written notice to each holder of Class A-[•] Preferred Stock stating (A) whether such Preferred Dividend will be paid in cash or by issuance and
delivery of PIK Shares and (B) if such Preferred Dividend will be paid by issuance and delivery of PIK Shares, the amount of PIK Shares that will be issued and delivered. If the Corporation fails to send such written notice on or before the
record date for the determination of stockholders entitled to receive any Preferred Dividend, then the Corporation will be deemed to have irrevocably elected to pay such Preferred Dividend by issuance and delivery of PIK Shares. 

 Section 4. Voting Rights. Except as otherwise provided herein or as otherwise
required by the DGCL, the Class A-[•] Preferred Stock shall have no voting rights. However, as long as any shares of Class A-[•] Preferred Stock are
outstanding, the Corporation shall not, without the affirmative vote of the Holders of a majority of the then outstanding shares of the Class A-[•] Preferred Stock, (i) alter or change adversely
the powers, preferences or rights given to the Class A-[•] Preferred Stock or alter or amend this Certificate of Designation, amend or repeal any provision of, or add any provision to, the
Certificate of Incorporation or bylaws of the Corporation, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of preferred stock, if such action would adversely alter or change
the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Class A-[•] Preferred Stock in a manner materially different than the effect on the Common Stock,
regardless of whether any of the foregoing actions shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise, (ii) issue further shares of
Class A-[•] Preferred Stock or increase or decrease (other than by conversion) the number of authorized shares of Class A-[•] Preferred Stock, or
(iii) enter into any agreement with respect to any of the foregoing. 
 Section 5. Liquidation. 

(a) Liquidation Preference. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary (a
“Liquidation”), after satisfaction of all liabilities and obligations to creditors of the Corporation and before any distribution or payment shall be made to holders of the Common Stock, each Holder shall be entitled receive
with respect to a share of Class A-[•] Preferred Stock, out of the assets of the Corporation or proceeds thereof, an amount equal to the Class A-[•]
Original Issue Price for such share of Class A-[•] Preferred Stock, plus all accrued but unpaid dividends thereon. If upon such Liquidation there are not sufficient assets or proceeds to make payment
in full to all Holders, then the assets or proceeds shall be distributed pari passu among the Holders and the holders of any other series of Class A Preferred Stock ratably in proportion to the full amounts to which they would otherwise
be respectively entitled. 
 (b) Remaining Assets. After the payment of the full liquidation preference of the
Class A-[•] Preferred Stock, as set forth in Section 5(a) above, the remaining assets of the Corporation available for distribution to its stockholders shall be distributed ratably to the
holders of the shares of Common Stock and Class A-[•] Preferred Stock. 
 (c) Notwithstanding the
foregoing, upon any Liquidation, then each Holder shall be entitled to receive, for each share of Class A-[•] Preferred Stock then held, out of the proceeds available for distribution, the greater of
(i) the amount of cash, securities or other property to which such holder would be entitled to receive with respect to such shares in a Liquidation pursuant to Section 5(a) (without giving effect to this Section 5(c)) (the
“Class A-[•] Preference Amount”) or (ii) the amount of cash, securities or other property to which
such holder would be entitled to receive in a Liquidation with respect to such shares if such shares had been converted to Common Stock immediately prior to such Liquidation, giving effect to this Section 5(c) with respect to all shares of Class A-[•] Preferred Stock. 
 (d) For purposes of this Section 5, a Liquidation shall be deemed to include
the occurrence after the date hereof of either of (i) the Corporation merges into or consolidates with any other entity, or any entity merges into or consolidates with the Corporation and, after giving effect to such transaction, the
stockholders of the Corporation immediately prior to such transaction own less than 50% of the aggregate voting power of the Corporation or the successor entity of such transaction or (ii) the Corporation sells, leases, licenses or transfers
all or substantially all of its assets to another person or entity and the stockholders of the Corporation immediately prior to such transaction own less than 50% of the aggregate voting power of the acquiring entity immediately after the
transaction (each a “Deemed Liquidation”). 

 (e) In the event of a Deemed Liquidation, if any portion of the consideration payable to the stockholders of the
Corporation is (i) placed into escrow or subject to a holdback (the “Escrowed or Heldback Initial Consideration”) and/or (ii) subject to contingencies, including, without limitation, pursuant to contingent value
rights (the “Contingent Consideration,” which term, for clarity, excludes any Escrowed Initial Consideration), then the definitive agreement with respect to such Deemed Liquidation shall provide that (A) all
consideration other than the Contingent Consideration (the “Initial Consideration,” which term, for clarity, includes any Escrowed or Heldback Initial Consideration) shall be allocated among the holders of capital stock of
the Corporation in accordance with Sections 5(a), 5(b) and 5(d) as if the Initial Consideration were the only consideration payable in connection with such Deemed Liquidation and (B) any Contingent Consideration which becomes payable to the
stockholders of the Corporation shall be allocated among the holders of capital stock of the Corporation in accordance with Sections 5(a), 5(b) and 5(d) after taking into account the previous payment of the Initial Consideration and any previously
paid Contingent Consideration as part of the same transaction. 
 Section 6. Conversion. 

(a) Conversions at Option of Holder. Each share of Class A-[•] Preferred Stock shall be convertible,
at any time and from time to time from and after the Issuance Date, at the option of the Holder thereof, into a number of shares of Common Stock equal to the product of the Conversion Numerator and the number of shares of Class A-[•] Preferred Stock to be converted. Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a “Notice
of Conversion”), duly completed and executed. Other than a conversion following a Fundamental Transaction or following a notice provided for under Section 7(d)(ii) hereof, the Notice of Conversion must specify at least a number of
shares of Class A-[•] Preferred Stock to be converted equal to the lesser of (x) 100 shares (such number subject to appropriate adjustment following the occurrence of an event specified in
Section 7(a) hereof) and (y) the number of shares of Class A-[•] Preferred Stock then held by the Holder. Provided the Corporation’s transfer agent is participating in the Depository
Trust Company (“DTC”) Fast Automated Securities Transfer program, the Notice of Conversion may specify, at the Holder’s election, whether the applicable Conversion Shares shall be credited to the DTC participant account
nominated by the Holder through DTC’s Deposit Withdrawal Agent Commission system (a “DWAC Delivery”). The “Conversion Date”, or the date on which a conversion shall be deemed effective, shall be
defined as the Trading Day that the Notice of Conversion, completed and executed, is sent by facsimile or other electronic transmission to, and received during regular business hours by, the Corporation; provided that the original certificate(s) (if
any) representing such shares of Class A-[•] Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion, are received by the Corporation within two (2) Trading
Days thereafter. In all other cases, the Conversion Date shall be defined as the Trading Day on which the original shares of Class A-[•] Preferred Stock being converted, duly endorsed, and the
accompanying Notice of Conversion, are received by the Corporation. The calculations set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error. 

(b) Conversion Ratio. The “Conversion Ratio” for each share of Class A-[•]
Preferred Stock shall be equal to the Conversion Numerator divided by the Conversion Denominator. The “Conversion Numerator” shall equal ten and the “Conversion Denominator” shall equal one (in
each case, subject to adjustment as set forth in this Certificate of Designation). 
 (c) Beneficial Ownership Limitation. Notwithstanding anything
herein to the contrary, the Corporation shall not effect any conversion of the Class A-[•] Preferred Stock, and a Holder shall not have the right to convert any portion of the Class A-[•] Preferred Stock, to the extent that, after giving effect to an attempted conversion set forth on an applicable Notice of Conversion, such attempted conversion would result in Holder (together
with such Holder’s Affiliates, and any other Person whose beneficial ownership 

 
of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) or Section 16 of the Exchange Act and the applicable regulations of the Commission, including
any “group” of which the Holder is a member (the foregoing, “Attribution Parties”)) beneficially owning a number of shares of Common Stock in excess of the Beneficial Ownership Limitation (as defined below). For
purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the
Class A-[•] Preferred Stock subject to the Notice of Conversion with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon
(i) conversion of the remaining, unconverted shares of Class A-[•] Preferred Stock beneficially owned by such Holder or any of its Attribution Parties, and (ii) exercise or conversion of
the unexercised or unconverted portion of any other securities of the Corporation (including any warrants) beneficially owned by such Holder or any of its Attribution Parties that, in the case of both (i) and (ii), are subject to a limitation
on conversion or exercise similar to the limitation contained herein. For purposes of this Section 6(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the applicable regulations of the
Commission. In addition, for purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable regulations of the Commission. For purposes of this Section 6(c), in determining the number
of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (A) the Corporation’s most recent periodic or annual filing with the Commission, as
the case may be, (B) a more recent public announcement by the Corporation that is filed with the Commission, or (C) a more recent notice by the Corporation or the Corporation’s transfer agent to the Holder setting forth the number of
shares of Common Stock then outstanding. Upon the written request of a Holder (which may be by email), the Corporation shall, within three (3) Trading Days thereof, confirm in writing to such Holder (which may be via email) the number of shares
of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Corporation, including shares of Class A-[•] Preferred Stock, by such Holder or its Attribution Parties since the date as of which such number of outstanding shares of Common Stock was last publicly reported or confirmed to the Holder.
The “Beneficial Ownership Limitation” shall initially be 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock pursuant to such Notice
of Conversion (to the extent permitted pursuant to this Section 6(c)). The Corporation shall be entitled to rely on representations made to it by the Holder in any Notice of Conversion regarding its Beneficial Ownership Limitation.
Notwithstanding the foregoing, by written notice to the Corporation, which will not be effective until the sixty-first (61st) day after such notice is delivered to the Corporation, the Holder may
reset the Beneficial Ownership Limitation percentage to a higher or lower percentage. Upon such a change by a Holder of the Beneficial Ownership Limitation, the Beneficial Ownership Limitation may not be further amended by such Holder without first
providing the minimum 61-day notice required by this Section 6(c). Notwithstanding the foregoing, at any time following notice of a Fundamental Transaction (as defined below), the Holder may waive and/or
change the Beneficial Ownership Limitation effective immediately upon written notice to the Corporation and may reinstitute a Beneficial Ownership Limitation at any time thereafter effective immediately upon written notice to the Corporation. 

(d) Mechanics of Conversion
 (i) Delivery of Certificate
or Electronic Issuance Upon Conversion. Not later than three Trading Days after the applicable Conversion Date, or if the Holder requests the issuance of physical certificate(s), two (2) Trading Days after receipt by the Corporation of the
original certificate(s) representing such shares of Class A-[•] Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion (the “Share Delivery
Date”), the Corporation shall (A) deliver, or cause to be delivered, to the converting Holder a physical certificate or certificates representing the number of Conversion Shares being acquired upon the conversion of shares of Class A-[•] Preferred Stock, or (B) in the case of a DWAC Delivery (if 

 
so requested by the Holder), electronically transfer such Conversion Shares by crediting the DTC participant account nominated by the Holder through DTC’s DWAC system. If in the case of any
Notice of Conversion such certificate or certificates are not delivered to or as directed by or, in the case of a DWAC Delivery, such shares are not electronically delivered to or as directed by, the applicable Holder by the Share Delivery Date, the
applicable Holder shall be entitled to elect to rescind such Conversion Notice by written notice to the Corporation at any time on or before its receipt of such certificate or certificates for Conversion Shares or electronic receipt of such shares,
as applicable, in which event the Corporation shall promptly return to such Holder any original Class A-[•] Preferred Stock certificate delivered to the Corporation and such Holder shall promptly
return to the Corporation any Common Stock certificates or otherwise direct the return of any shares of Common Stock delivered to the Holder through the DWAC system, representing the shares of
Class A-[•] Preferred Stock unsuccessfully tendered for conversion to the Corporation. 
 (ii)
Obligation Absolute. Subject to Section 6(c) hereof and subject to Holder’s right to rescind a Conversion Notice pursuant to Section 6(d)(i) above, the Corporation’s obligation to issue and deliver the Conversion Shares
upon conversion of Class A-[•] Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver
or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or
any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such
Holder in connection with the issuance of such Conversion Shares. Subject to Section 6(c) hereof and subject to Holder’s right to rescind a Conversion Notice pursuant to Section 6(d)(i) above, in the event a Holder shall elect to
convert any or all of its Class A-[•] Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or anyone associated or affiliated with such Holder has been
engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Class A-[•]
Preferred Stock of such Holder shall have been sought and obtained by the Corporation, and the Corporation posts a surety bond for the benefit of such Holder in the amount of 150% of the value of the Conversion Shares into which would be converted
the Class A-[•] Preferred Stock which is subject to such injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of
which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the Corporation shall, subject to Section 6(c) hereof and subject to Holder’s right to rescind a Conversion Notice pursuant to
Section 6(d)(i) above, issue Conversion Shares upon a properly noticed conversion. Nothing herein shall limit a Holder’s right to pursue actual damages for the Corporation’s failure to deliver Conversion Shares within the period
specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief; provided that Holder shall not
receive duplicate damages for the Corporation’s failure to deliver Conversion Shares within the period specified herein. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section
hereof or under applicable law. 
 (iii) Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times reserve
and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Class A-[•] Preferred Stock, free from preemptive rights or any
other actual contingent purchase rights of Persons other than the Holders of the Class A-[•] Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable
(taking into account the adjustments of Section 7) upon the conversion of all outstanding shares of Class A-[•] Preferred Stock. The Corporation covenants that all shares of Common Stock that
shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, non-assessable and free and clear of all liens and other encumbrances. 

 (iv) Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall
be issued upon the conversion of the Class A-[•] Preferred Stock. In determining the number of shares of Common Stock to be issued upon the conversion of the
Class A-[•] Preferred Stock, such number shall be rounded up in the case of any resulting fractional number of shares of Common Stock. 

(v) Transfer Taxes. The issuance of certificates (or book entry notations) for shares of the Common Stock upon conversion of the Class A-[•] Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates (or such book
entry notation), provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate (or such book entry notation) upon conversion in a name
other than that of the registered Holder(s) of such shares of Class A-[•] Preferred Stock and the Corporation shall not be required to issue or deliver such certificates (or such book entry notation)
unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid. 

(e) Status as Stockholder. Upon each Conversion Date: (i) the shares of Class A-[•] Preferred
Stock being converted shall be deemed converted into shares of Common Stock; and (ii) the Holder’s rights as a holder of such converted shares of Class A-[•] Preferred Stock shall cease and
terminate, excepting only the right to receive certificates (or book entry notations) for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the
Corporation to comply with the terms of this Certificate of Designation. In all cases, the Holder shall retain all of its rights and remedies for the Corporation’s failure to convert Class A-[•]
Preferred Stock. 
 Section 7. Certain Adjustments. 

(a) Stock Dividends and Stock Splits. If the Corporation, at any time while any shares of Class A-[•]
Preferred Stock are outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock with respect to the then outstanding shares of Common Stock; (ii) subdivides outstanding shares
of Common Stock into a larger number of shares; or (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then the Conversion Numerator shall be multiplied by a fraction of
which the numerator shall be the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding
immediately after such event (excluding any treasury shares of the Corporation). Any adjustment made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to
receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. 
 (b)
Fundamental Transaction. If, at any time while any shares of Class A-[•] Preferred Stock are outstanding, (i) the Corporation, directly or indirectly, in one or more related transactions
effects any merger or consolidation of the Corporation with or into another Person, (ii) the Corporation, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any direct or indirect purchase offer, tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which holders of Common Stock are
permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 35% or more of the outstanding Common Stock, (iv) the Corporation, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other

 
securities, cash or property, (v) the Corporation, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination
(including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common
Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination
and excluding shares acquired upon conversion of any currently outstanding convertible securities in accordance with the terms thereof as in effect on the date hereof) (each, a “Fundamental Transaction”), then as of the
effective date and time of the Fundamental Transaction (the “Effective Time”), each outstanding share of Class A-[•] Preferred Stock shall be canceled without any further
action on the part of the Corporation or the Holder thereof, and in consideration for such cancellation, each Holder shall automatically receive, for each Conversion Share that would have been issuable had such cancelled shares of Class A-[•] Preferred Stock been converted immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash and other property receivable upon the
effectiveness of such Fundamental Transaction (the “Exchange Property”) as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental
Transaction, the holder of one share of Common Stock (the “Alternate Consideration”); provided, however that in the event that the Fundamental Transaction is a Deemed Liquidation, each Holder shall be entitled to receive with
respect to each outstanding share of Class A-[•] Preferred Stock the greater of (1) the Class A-[•] Preference Amount or (2) the amount of
cash, securities or other property to which such holder would be entitled to receive in such Deemed Liquidation with respect to such shares if such shares had been converted to Common Stock immediately prior to such Deemed Liquidation (for clarity,
without duplication of amounts payable pursuant to Section 5). The amount of Exchange Property receivable upon any Fundamental Transaction shall be determined based upon the Conversion Ratio in effect at such Effective Time.  

If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holders shall be
given the same choice as to the Alternate Consideration it receives upon any conversion of their shares of Class A-[•] Preferred Stock following such Fundamental Transaction should such shares of Class A-[•] Preferred Stock remain outstanding after such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions should any shares of
Class A-[•] Preferred Stock remain outstanding after a Fundamental Transaction, any successor to the Corporation or surviving entity in such Fundamental Transaction shall file a new Certificate of
Designation with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate Consideration. The terms of
any agreement to which the Corporation is a party and pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 7(b) and ensuring
that the outstanding shares of Class A-[•] Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. 

The Corporation (or any successor) shall, prior to any Fundamental Transaction, provide written notice to the Holders of the occurrence of such event and of
the kind and amount of the cash, securities or other property that constitute the Exchange Property. Failure to deliver such notice shall not affect the operation of this Section 7. 

The Corporation shall not enter into any agreement for a transaction constituting a Fundamental Transaction that would interfere with or prevent (as
applicable) conversion of the Class A-[•] Preferred Stock into the Exchange Property in a manner that is consistent with and gives effect to this Section 7. 

 (c) Calculations. All calculations under this Section 7 shall be made to the nearest cent or the
nearest 1/100th of a share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the number of shares of Common Stock issued and outstanding
(excluding any treasury shares of the Corporation). 
 (d) Notice to the Holders. 

(i) Adjustment to Conversion Price. Whenever the Conversion Ratio is adjusted pursuant to any provision of this Section 7, the Corporation shall
promptly deliver to each Holder a notice setting forth the Conversion Ratio after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 

(ii) Other Notices. If (A) the Corporation shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the
Corporation shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Corporation shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any
shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation
is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Corporation shall
authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of the
shares of Class A-[•] Preferred Stock, and, except if such notice and the contents thereof shall be deemed to constitute material non-public information, shall
cause to be delivered to each Holder at its last address as it shall appear upon the stock books of the Corporation, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date
on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend,
distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is
expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share
exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. 

Section 8. Miscellaneous. 
 (a)
Notices. Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice of Conversion, shall be in writing and delivered personally, by facsimile, via email, or sent
by a nationally recognized overnight courier service, addressed to the Corporation, at 11804 North Creek Parkway South Bothell, WA 98011, Attn: Secretary, with a copy (which shall not constitute notice) to: Cooley LLP, 1700 Seventh Avenue, Suite

or other communications or deliveries to be provided by the Corporation hereunder shall be in writing and delivered personally, by facsimile, email, or sent by a nationally recognized overnight courier service addressed to each Holder at the
facsimile number, email address or mailing address of such Holder appearing on the books of the Corporation, or if no such facsimile number, email address, or mailing address appears on the books of the Corporation, at the principal place of
business of such Holder. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of: (i) the date of transmission, if such notice or communication is

 
delivered via facsimile or email prior to 5:30 p.m. (New York City time) on any date, (ii) the date immediately following the date of transmission, if such notice or communication is
delivered via facsimile or email between 5:30 p.m. and 11:59 p.m. (New York City time) on any date, (iii) the second Business Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon
actual receipt by the party to whom such notice is required to be given. 
 (b) Lost or Mutilated
Class A-[•] Preferred Stock Certificate. If a Holder’s Class A-[•] Preferred Stock certificate, if applicable,
shall be mutilated, lost, stolen or destroyed, the Corporation shall execute and deliver, if requested by the Holder, in exchange and substitution for and upon cancellation of a mutilated certificate, or in lieu of or in substitution for a lost,
stolen or destroyed certificate, a new certificate for the shares of Class A-[•] Preferred Stock so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or
destruction of such certificate, and of the ownership thereof, reasonably satisfactory to the Corporation and, in each case, customary and reasonable indemnity, if requested. Applicants for a new certificate under such circumstances shall also
comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Corporation may prescribe. 
 (c)
Waiver. Any waiver by the Corporation or a Holder of a breach of any provision of this Certificate of Designation shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other
provision of this Certificate of Designation or a waiver by any other Holders. The failure of the Corporation or a Holder to insist upon strict adherence to any term of this Certificate of Designation on one or more occasions shall not be considered
a waiver or deprive that party (or any other Holder) of the right thereafter to insist upon strict adherence to that term or any other term of this Certificate of Designation. Any waiver by the Corporation or a Holder must be in writing.
Notwithstanding any provision in this Certificate of Designation to the contrary, any provision contained herein and any right of the Holders of Class A-[•] Preferred Stock granted hereunder may be
waived as to all shares of Class A-[•] Preferred Stock (and the Holders thereof) upon the written consent of: (i) the Holders of a majority of the shares of
Class A-[•] Preferred Stock then outstanding, and (ii) Redmile Group, LLC, but only to the extent that the Holders of a majority of the shares of
Class A-[•] Preferred Stock then outstanding are not funds, accounts or entities managed by Redmile Group, LLC or any of its Affiliates, without the prior consent of the Company unless a higher
percentage is required by the DGCL, in which case the written consent of the Holders of not less than such higher percentage shall be required. 
 (d)
Severability. If any provision of this Certificate of Designation is invalid, illegal or unenforceable, the balance of this Certificate of Designation shall remain in effect, and if any provision is inapplicable to any Person or circumstance,
it shall nevertheless remain applicable to all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable law governing usury, the applicable rate of interest due
hereunder shall automatically be lowered to equal the maximum rate of interest permitted under applicable law. 
 (e) Next Business Day. Whenever any
payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day. 
 (f)
Headings. The headings contained herein are for convenience only, do not constitute a part of this Certificate of Designation and shall not be deemed to limit or affect any of the provisions hereof. 

(g) Status of Converted Class A-[•] Preferred Stock. If any shares of Class A-[•] Preferred Stock shall be converted by the Corporation, such shares shall resume the status of authorized but unissued shares of preferred stock and shall no longer be designated as Class A-[•] Preferred Stock. 
 (h) Redemption by the Corporation. The
Class A-[•] Preferred Stock shall not be redeemable by the Corporation. 

 (i) Transfer Agent, Registrar and Conversion Agent. The duly appointed transfer agent, registrar,
conversion and dividend paying agent for shares of Class A-[•] Preferred Stock shall be American Stock Transfer & Trust Company, LLC (the “Transfer Agent”). The
Corporation may, in its sole discretion, remove the Transfer Agent in accordance with the agreement between the Corporation and the Transfer Agent; provided that the Corporation shall appoint a successor transfer agent who shall accept such
appointment prior to the effectiveness of such removal. Upon any such removal or appointment, the Corporation shall send notice thereof by first-class mail, postage prepaid, to the Holders of shares of
Class A-[•] Preferred Stock.

 ANNEX A 

NOTICE OF CONVERSION 
 (TO BE
EXECUTED BY THE REGISTERED HOLDER 
 IN ORDER TO CONVERT SHARES OF CLASS A-[•] PREFERRED STOCK)

 The undersigned Holder hereby elects to convert the number of shares of Class A-[•] Preferred Stock
indicated below, represented by stock certificate No(s). or book entry notation (the “Preferred Stock Certificates”), into shares of common stock, par value $0.0001 per share (the “Common Stock”), of
Alder BioPharmaceuticals, Inc., a Delaware corporation (the “Corporation”), as of the date written below. If securities are to be issued in the name of a person other than the undersigned, the undersigned will pay all
transfer taxes payable with respect thereto. Capitalized terms utilized but not defined herein shall have the meaning ascribed to such terms in that certain Certificate of Designation of Preferences, Rights and Limitations of Class A-[•] Convertible Preferred Stock (the “Certificate of Designation”) filed by the Corporation with the Delaware Secretary of State on January [•], 2018, as may be amended
or restated from time to time. 
 As of the date hereof, the number of shares of Common Stock beneficially owned by the undersigned Holder (together with
such Holder’s Affiliates, and any other Person whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) or Section 16 of the Exchange Act and the applicable regulations of the
Commission, including any “group” of which the Holder is a member (the foregoing, “Attribution Parties”)), including the number of shares of Common Stock issuable upon conversion of the Class A-[•] Preferred Stock subject to this Notice of Conversion, but excluding the number of shares of Common Stock which are issuable upon (A) conversion of the remaining, unconverted Class A-[•] Preferred Stock beneficially owned by such Holder or any of its Attribution Parties, and (B) exercise or conversion of the unexercised or unconverted portion of any other securities of the
Corporation (including any warrants) beneficially owned by such Holder or any of its Attribution Parties that are subject to a limitation on conversion or exercise similar to the limitation contained in Section 6(c) of the Certificate of
Designation, is, %. For purposes of the foregoing, the percentage was calculated, in accordance with Section 6(c) the Certificate of Designation, based on the number of outstanding shares of Common Stock as stated in the most recent of
the following: (i) the Corporation’s most recent periodic or annual filing with the Commission, as the case may be, (ii) a more recent public announcement by the Corporation that is filed with the Commission, or (iii) a more
recent notice by the Corporation or the Corporation’s transfer agent to the Holder setting forth the number of shares of Common Stock then outstanding. For purposes hereof, beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act and the applicable regulations of the Commission. In addition, for purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable regulations of the
Commission.

ALDER BIOPHARMACEUTICALS, INC. 

WARRANT TO PURCHASE CLASS A-1 CONVERTIBLE PREFERRED STOCK 

Original Issue Date: ________________ 
 Alder
BioPharmaceuticals, Inc., a Delaware corporation (the “Company”), hereby certifies that, for value received, [•] or its permitted registered assigns (the “Holder”), is entitled to purchase from
the Company up to a total of 75,0002 shares of Class A-1 Convertible Preferred Stock, $0.0001 par value per share (as adjusted from time to time as
provided in Section 9 below, the “Class A-1 Stock”), of the Company (each such share, a “Warrant
Share” and all such shares, the “Warrant Shares”) at an exercise price per share equal to $[•]3 per share (as adjusted from time to time as provided in
Section 9 below, the “Exercise Price”), at any time and from time to time on or after the date hereof and through and including 5:30 p.m., New York City time, on [•]4 (the “Expiration Date”), and subject to the following terms and conditions: This Warrant (this “Warrant”) is being issued pursuant to that certain
Preferred Stock Purchase Agreement, dated January 7, 2018, by and among the Company and the Buyers identified therein (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase
Agreement”). 
 1. Definitions. In addition to the terms defined elsewhere in this Warrant, capitalized terms that are not otherwise
defined herein have the meanings given to such terms in the Purchase Agreement. 
 2. Registration of Warrants. The Company shall register this
Warrant, upon records to be maintained by the Company for that purpose, which may be a third-party transfer agent (the “Warrant Register”), in the name of the record Holder (which shall include the initial Holder or, as the
case may be, any registered assignee to which this Warrant is permissibly assigned hereunder) from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof
or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary. 
  

 

	2 	Subject to adjustment for any recapitalization, stock dividend, stock split, stock combination or other similar transaction effected after the date of the Preferred Stock Purchase Agreement. 

	3 	[Note: To be equal to the price per share for the initial purchase under the Preferred Stock Purchase Agreement.] Subject to adjustment for any recapitalization, stock dividend, stock split, stock combination or other
similar transaction effected after the date of the Preferred Stock Purchase Agreement but before the Original Issue Date. 

	4 	To be the date ten years from the Original Issue Date

 3. Registration of Transfers. Subject to compliance with all applicable securities laws, the Company shall
register the transfer of all or any portion of this Warrant in the Warrant Register, upon (i) surrender of this Warrant, with an assignment, in the form attached as Schedule 2 hereto, duly completed and signed, to the Company’s
transfer agent or to the Company at its address specified in the Purchase Agreement and (ii) (x) at the request of the Company, delivery of an opinion of counsel reasonably satisfactory to the Company to the effect that the transfer of such
portion of this Warrant may be made pursuant to an available exemption from the registration requirements of the Securities Act and all applicable state securities or blue sky laws (other than in connection with any transfer (1) pursuant to an
effective registration statement, (2) to the Company, (3) pursuant to Rule 144 (provided that such Holder provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the
securities may be sold pursuant to such rule) or (4) in connection with a bona fide pledge) and (y) delivery by the transferee of a written statement to the Company certifying that the transferee is an “accredited investor” as
defined in Rule 501(a) under the Securities Act and making the representations and certifications set forth in the Purchase Agreement. Upon any such registration or transfer, a new warrant to purchase
Class A-1 Stock in substantially the form of this Warrant (any such new warrant, a “New Warrant”) evidencing the portion of this Warrant so transferred shall be promptly issued to
the transferee, and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be promptly issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance by such transferee of all of the rights and obligations in respect of the New Warrant that the Holder has in respect of this Warrant. The Company shall promptly prepare, issue and deliver at its own expense any New Warrant under this
Section 3. 
 4. Exercise and Duration of Warrant. 

(a) All or any part of this Warrant shall be exercisable by the registered Holder in any manner permitted by
Section 10 below at any time and from time to time on or after the date hereof and through and including 5:30 p.m., New York City time, on the Expiration Date. Notwithstanding the foregoing, this Warrant shall automatically
be deemed to be exercised in full in the form of a “cashless exercise” pursuant to the provisions of Section 10 below, without any further action on behalf of the Holder, immediately prior to the time this Warrant
would otherwise expire pursuant to the preceding sentence. The Company shall promptly thereafter deliver to the Holder the calculation made pursuant to the preceding sentence, together with any Warrant Shares to which the Holder is entitled. 

(b) Without limiting the automatic “cashless exercise” contained in Section 4(a), the Holder may exercise
this Warrant by delivering to the Company (i) an exercise notice, in the form attached as Schedule 1 hereto (the “Exercise Notice”), completed and duly signed, and (ii) payment of the Exercise Price for the
number of Warrant Shares as to which this Warrant is being exercised (which may take the form of a “cashless exercise” if so indicated in the Exercise Notice and if a “cashless exercise” may occur at such time pursuant to
Section 10 below) within one Trading Day (as defined in Section 5(a) below) following the Exercise Date (as defined herein). The date on which the Exercise Notice is delivered to the Company (as determined in
accordance with the notice provisions hereof) is an “Exercise Date.” No ink-original Exercise Notice shall be required, nor shall any medallion guarantee (or other type of guarantee or
notarization) of any Exercise Notice form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise
Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares. 

  
 3 

 5. Delivery of Warrant Shares. 

(a) Upon exercise of this Warrant, the Company shall promptly (but in no event later than two Trading Days after the Exercise Date) issue or
cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate, (i) a certificate for the Warrant Shares issuable upon such exercise or (ii) an electronic
delivery of the Warrant Shares to the Holder’s account at the Depository Trust Company (“DTC”) or a similar organization (if the Warrant Shares are DTC eligible at the time of exercise); provided, that if the
Warrant Shares are not freely transferable without restriction under Rule 144 under the Securities Act (“Rule 144”) by Holders who are not Affiliates of the Company, such Holder shall receive a certificate for the Warrant
Shares issuable upon such exercise with appropriate restrictive legends. The Holder, or any Person permissibly so designated by the Holder to receive Warrant Shares, shall be deemed to have become the holder of record of such Warrant Shares as of
the Exercise Date. If the Warrant Shares are to be issued free of all restrictive legends, the Company shall, upon the written request of the Holder, use its best efforts to deliver, or cause to be delivered, the Warrant Shares hereunder
electronically through DTC or another established clearing corporation performing similar functions, if available. For purposes of this Warrant, “Trading Day” means a day on which the common stock, $0.0001 par value per share
of the Company (the “Common Stock”), is listed or quoted and traded on its Principal Market; provided, that in the event that the Common Stock is not listed or quoted, then Trading Day shall mean any day other than
Saturday, Sunday, or any other day on which banking institutions in the State of New York are authorized by law or executive action to close (a “Business Day”); provided further, that “Trading Day” shall not
include any day on which the Common Stock is scheduled to trade on such exchange or market for less than 4.5 hours or any day that the Common Stock is suspended from trading during the final hour of trading on such exchange or market (or if such
exchange or market does not designate in advance the closing time of trading on such exchange or market, then during the hour ending at 4:00 p.m., New York City time). 

(b) To the extent permitted by law, the Company’s obligations to issue and deliver Warrant Shares in accordance with and subject to the
terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to
enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company (other than breaches related to this Warrant or the Purchase
Agreement) or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance that might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant
Shares. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the
Company’s failure to timely deliver certificates representing the Warrant Shares (or uncertificated Warrant Shares) as required pursuant to the terms hereof. 

6. Charges, Taxes and Expenses. Issuance and delivery of certificates for Warrant Shares (or uncertificated Warrant Shares) issuable upon exercise of
this Warrant shall be made without charge to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates (or uncertificated shares of Common Stock), all of which
taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares (or
uncertificated Warrant Shares) or the Warrants in a name other than that of the Holder or an Affiliate thereof. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or
receiving Warrant Shares upon exercise hereof. 
 7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to

  
 4 

 
the Company of such loss, theft or destruction (in such case) and, in each case, a customary and reasonable indemnity and surety bond, if requested by the Company. Applicants for a New Warrant
under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant,
then the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the New Warrant. 
 8.
Reservation of Warrant Shares. The Company covenants that at all times while this Warrant is outstanding it will reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Class A-1 Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares that are initially issuable and deliverable upon the
exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9 below). The Company covenants that
all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable and free from all
taxes, liens and charges created by the Company in respect of the original issuance thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue). The Company covenants that at all times while this Warrant is
outstanding it will reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved, solely for the purpose of enabling it to issue shares of Common Stock upon conversion of the Warrant Shares (the
“Underlying Common”), the number of shares of Common Stock issuable upon conversion of the Warrant Shares. The Company covenants that all Underlying Common so issuable and deliverable shall, upon issuance in accordance with
the provisions of the Company’s Certificate of Incorporation and the Certificate of Designation of Preferences, Rights and Limitations Class A-1 Convertible Preferred Stock (the “Charter
Documents”), be duly and validly authorized, issued and fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the original issuance thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue). The Company will take all such action as may be reasonably necessary to assure that such shares of Class A-1 Stock and Common Stock may be issued as
provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Class A-1 Stock or the Common Stock
may be listed. 
 9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to
adjustment from time to time as set forth in this Section 9. 
 (a) Stock Dividends and Splits. If the
Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Class A-1 Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Class A-1 Stock, (ii) subdivides its outstanding shares of Class A-1 Stock into a larger number of shares, (iii) combines (by combination, reverse stock
split or otherwise) its outstanding shares of Class A-1 Stock into a smaller number of shares, or (iv) issues by reclassification of shares of Class A-1
Stock or recapitalization any shares of capital stock of the Company, then in each such case the Exercise Price shall be adjusted to a price determined by multiplying the Exercise Price in effect immediately prior to the effective date of such event
by a fraction, the numerator of which shall be the number of shares of Class A-1 Stock outstanding on such effective date immediately before giving effect to such event and the denominator of which shall
be the number of shares of Class A-1 Stock outstanding immediately after giving effect to such event. Any adjustment made pursuant to clause (i) of this Section 9(a) shall
become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii), (iii) or (iv) of this Section 9(a)
shall become effective immediately after the effective date of such subdivision, combination, reclassification or recapitalization. 

  
 5 

 (b) Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding,
distributes to all holders of Class A-1 Stock for no consideration (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by
Section 9(a)), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset, including cash (in each case, “Distributed Property”), except for any distributions
pursuant to a shareholders’ rights plan or similar takeover defense agreement or plan adopted by the Company, then, upon any exercise of this Warrant that occurs after the record date fixed for determination of stockholders entitled to receive
such distribution, the Holder shall be entitled to receive, in addition to the Warrant Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of such
number of Warrant Shares had the Holder been the record holder of such Warrant Shares immediately prior to such record date. 
 (c)
Fundamental Transactions. If, at any time while this Warrant is outstanding the Company effects a Fundamental Transaction (as defined in the Charter Documents), then the Holder shall have the right thereafter to receive, upon exercise of this
Warrant, the same amount and kind of securities, cash or property (net of the Exercise Price per Warrant Share then in effect) as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately
prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein (the “Alternate
Consideration”), and the Holder shall no longer have the right to receive Warrant Shares upon exercise of this Warrant. The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the
consummation thereof, any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or Person shall assume the obligation to deliver to the Holder, such Alternate
Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Warrant. The provisions of this Section 9(c) shall similarly apply to subsequent
transactions of an analogous type to any Fundamental Transaction. 
 (d) Number of Warrant Shares. Simultaneously with any adjustment
to the Exercise Price pursuant to Section 9(a) above, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the
aggregate Exercise Price payable hereunder for the increased or decreased number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment. 

(e) Calculations. All calculations under this Section 9 shall be made to the nearest cent or the nearest
share, as applicable. 
 (f) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this
Section 9, the Company at its expense will, at the written request of the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant and prepare a certificate setting forth such
adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments
and showing in reasonable detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent. 

(g) Notice of Corporate Events. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other
distribution of cash, securities or other property in respect of its Class A-1 Stock or Common Stock, including, without limitation, any granting of rights or warrants to subscribe for or purchase any
capital stock of the Company, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction, or (iii) authorizes the 

  
 6 

 
voluntary dissolution, liquidation or winding up of the affairs of the Company, then, except if such notice and the contents thereof shall be deemed to constitute material non-public information, the Company shall deliver to the Holder a notice of such transaction at least ten Business Days (provided such disclosure would not violate Regulation FD) prior to the applicable record or
effective date on which a Person would need to hold Class A-1 Stock in order to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice
or any defect therein shall not affect the validity of the corporate action required to be described in such notice. 
 (h) Adjustments to
Class A-1 Conversion Price. Without duplication of any other adjustment pursuant to this Section 9, the number of shares of Common Stock issuable upon conversion of the
Warrant Shares shall be subject to adjustment from time to time in the manner set forth in the Charter Documents. The provisions set forth for the Class A-1 Stock in the Charter Documents relating to the
above in effect as of the Original Issue Date may not be amended, modified or waived, without the prior written consent of the Holder unless such amendment, modification or waiver affects the Holder in the same manner as they affect all other
stockholders of the same series of shares granted to the Holder. For so long as this Warrant is outstanding, the Company shall deliver to the Holder each certificate of adjustment sent to the holders of the
Class A-1 Stock pursuant to the Certificate of Designation with respect to the Class A-1 Stock. 

10. Payment of Exercise Price. The Holder shall pay the Exercise Price in immediately available funds; provided, however, that the Holder may,
in its sole discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows: 

X = Y[(A-B)/A] 
 where:

 X = the number of Warrant Shares to be issued to the Holder. 

Y = the total number of Warrant Shares with respect to which this Warrant is being exercised. 

A = the fair market value (“FMV”) of one share of Class A-1 Stock on an as-converted to Common Stock basis, as determined below, on the Exercise Date. 
 B = the Exercise Price then in effect
for the applicable Warrant Shares at the time of such exercise. 
 For purposes of this Warrant, FMV shall be determined at the time of exercise and shall
mean the fair market value of the shares of Common Stock as determined as follows: 
 (a) if the Common Stock is traded on a securities
exchange, the value shall be deemed to be the VWAP on such exchange over the five Trading Day period ending three Trading Days prior to the date of determination; 

(b) if the Common Stock is actively traded over-the-counter,
the value shall be deemed to be the average of the closing bid over the five Trading Day period ending three Trading Days prior to the date of determination; or 

(c) if there is no active public market for the Common Stock, the value shall be the fair market value thereof, as determined in good faith by
the Board of Directors of the Company. 

  
 7 

 For purposes of Rule 144, it is intended, understood and acknowledged that the provisions above permitting
“cashless exercise” are intended, in part, to ensure that a full or partial exchange of this Warrant pursuant to such provisions will qualify as a conversion, within the meaning of paragraph (d)(3)(ii) of Rule 144, and the holding period
for the Warrant Shares shall be deemed to have commenced as to such original Holder, on the Original Issue Date. 
 In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares to be issued pursuant to the terms hereof (including, without limitation, the number of Warrant Shares issuable upon a “cashless exercise”),
the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed, provided that following such issuance to the Holder such dispute shall be resolved in accordance with Section 14(f) below.

 11. No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional
shares that would otherwise be issuable, the number of Warrant Shares to be issued shall be rounded down to the next whole number and the Company shall pay the Holder in cash the FMV for any such fractional shares. 

12. Notices. Any notices, consents or other communications required or permitted to be given under the terms of this Warrant (including, without
limitation, any Exercise Notice) must be in writing and will be deemed to have been delivered: (a) upon receipt, when delivered personally; (b) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or
electronically generated and kept on file by the sending party); (c) upon receipt, when sent by electronic message (provided the recipient responds to the message and confirmation of both electronic messages are kept on file by the sending party);
or (d) one Business Day after timely deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same. The addresses and facsimile numbers for such communications shall be as set
forth in the Purchase Agreement or at such other address and/or facsimile number and/or to the attention of such other person as the recipient party has specified by written notice given to each other party at least one Business Day prior to the
effectiveness of such change. Written confirmation of receipt (a) given by the recipient of such notice, consent or other communication, (b) mechanically or electronically generated by the sender’s facsimile machine containing the
time, date, and recipient facsimile number, (c) electronically generated by the sender’s electronic mail containing the time, date and recipient email address or (d) provided by a nationally recognized overnight delivery service,
shall be rebuttable evidence of receipt in accordance with clause (a), (b), (c) or (d) above, respectively. 
 13. Warrant Agent. The Company
shall initially serve as warrant agent under this Warrant. Upon 15 days’ notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation
resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or shareholders services business
shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the
Holder’s last address as shown on the Warrant Register. 
 14. Miscellaneous. 

(a) No Rights as a Stockholder; No Liabilities. The Holder, solely in such Person’s capacity as a holder of this Warrant, shall
not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the
Holder of this Warrant, any of the rights 

  
 8 

 
of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, recapitalization,
consolidation, merger, amalgamation, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to
receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities, whether such liabilities are asserted by the Company or by
creditors of the Company. 
 (b) Authorized Shares. 

(i) The Company will take all such action as may be necessary to assure that such Warrant Shares may be issued as provided herein without
violation of any applicable law or regulation or of any requirements of the Principal Market upon which the Class A-1 Stock or the Common Stock may be listed. 

(ii) Except and to the extent waived or consented to by the Holder, the Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder as set forth in this
Warrant against impairment. Without limiting the generality of the foregoing, the Company will (1) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par
value, (2) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (3) use commercially reasonable
efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant. 

(iii) Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in
the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof. 

(c) Successors and Assigns. Subject to the restrictions on transfer set forth in this Warrant and compliance with applicable securities
laws, this Warrant may be assigned by the Holder. This Warrant may not be assigned by the Company without the written consent of the Holder except to a successor in the event of a Fundamental Transaction. This Warrant shall be binding on and inure
to the benefit of the Company and the Holder and their respective successors and assigns. Subject to the preceding sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or
equitable right, remedy or cause of action under this Warrant. 
 (d) Amendment and Waiver. Except as otherwise provided herein, the
provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the prior written consent of the Holder. 

(e) Acceptance. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions
contained herein. 

  
 9 

 (f) Governing Law; Jurisdiction. The corporate laws of the State of Delaware shall govern
all issues concerning the relative rights of the Company and its stockholders. All other questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by the internal laws of the State of Delaware,

CENTRAL VALLEY COMMUNITY BANK 
DIRECTOR DEFERRED FEE AGREEMENT
This Agreement is entered into this 8th day of January, 2018 (the “Effective Date”) by and between CENTRAL VALLEY COMMUNITY BANK, a California-chartered commercial bank located in Fresno, California (the “Bank”), and ROBERT FLAUTT (the “Director”).
INTRODUCTION
To encourage the Director to remain a member of the Bank’s Board of Directors, the Bank is willing to provide to the Director an opportunity to defer Director’s fees.  The Bank will pay the Director’s deferred fees from its general assets.
AGREEMENT
The Director and the Bank agree as follows:
ARTICLE I.  DEFINITIONS
1.01    Definitions
Whenever used in this Agreement, the following words and phrases shall have the meanings specified:
		
	A.
	“Change of Control” means that any of the following events occur:

1.    Merger/Acquisition of Significant Share Ownership
Any one person, or more than one person acting as a group, acquires ownership of the Bank or Central Valley Community Bancorp that, together with stock held by such person or group, constitutes more than fifty percent (50%) of the total fair market value or total voting power of the stock.  However, if any one person or more than one person acting as a group, is considered to own more than fifty percent (50%) of the total fair market value or total voting power of the stock of the Bank or Central Valley Community Bancorp, the acquisition of additional stock by the same person or persons will not be considered to cause a Change of Control.  Further, an increase in the percentage of stock owned by any one person, or persons acting as a group, as a result of a transaction in which the Bank or Central Valley Community Bancorp acquires its stock in exchange for property will not be considered to cause a Change of Control; or
2.    Change in Board Composition
During any twelve (12)-month period, a majority of the members of the Board of Directors of the Bank or Central Valley Community Bancorp are replaced by Directors whose appointment or election is not endorsed by 

1

at least two-thirds of the members of the Board of Directors before the date of the appointment or election.  
Notwithstanding anything to the contrary, the term “Change of Control” shall be interpreted in accordance with Code section 409A.  
		
	B.
	“Code” means the Internal Revenue Code of 1986, as amended.

		
	C.
	“Deferral Account” or “Deferred Account “means the Bank’s accounting of the Director’s accumulated Deferrals plus accrued interest.

		
	D.
	“Deferrals “means the amount of the Director’s Fees which the Director elects to defer according to this Agreement.

		
	E.
	“Disability” means the Director’s inability to perform substantially all normal duties of a director, as determined by the Bank’s Board of Directors in its sole discretion.  As a condition to any benefits, the Bank may require the Director to submit to such physical or mental evaluations and tests as the Board of Directors deems appropriate.  

A Director shall only be considered to have a “Disability” if he or she (i) is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months; or (ii) is, by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering Bank employees.  Notwithstanding anything to the contrary, the terms “Disability” or “Disabled” shall be interpreted in accordance with Code section 409A.
		
	F.
	“Deferral Election Form” means the form attached as Exhibit A, as it may be modified from time to time by the Bank.

		
	G.
	“Distribution Election Form” means the form attached as Exhibit B, as it may be modified from time to time by the Bank.

		
	H.
	 “Fees” means the total directors fees payable to the Director during a calendar year.

		
	I.
	“Termination for Cause” means the Bank’s Board of Directors or a duly authorized committee of the Board of Directors determines at any time that the Director will not be nominated by the Board or committee for reelection as a Director after the expiration of his current term, or if the Director is removed as a director of the Bank, in either case because of the Director’s – 

1.    Gross negligence or gross neglect of duties, or 

2

2.    Commission of a felony, or commission of a misdemeanor involving moral turpitude, or
3.    Fraud, disloyalty, dishonesty, or willful violation of any law or significant policy of Central Valley Community Bancorp or the Bank, or
4.    Removal from service or permanent prohibition from participation in the conduct of the Bank’s affairs by an order issued under section 8(e)(4) or (g)(l) of the Federal Deposit Insurance Act [12 U.S.C. 1818(e)(4) or (g)(1)].
		
	J.
	“Termination of Service “means the Director ceasing to be a member for the Bank’s Board of Directors for any reason whatsoever.  A “Termination of Service” shall only have occurred if the termination of the Director’s membership on the Board of Directors constitutes a good-faith and complete termination of the Director’s board membership, as described in Treasury Regulations §1.409A-1(h)(2)(i).

ARTICLE II.  DEFERRAL ELECTION
2.01    Initial Election
The Director shall make an initial deferral election to defer all or a portion of his Fees under this Agreement by filing with the Bank a signed Deferral Election Form within thirty (30) days after the date of this Agreement.  The Deferral Election Form shall set forth the amount of Fees to be deferred prospectively and shall be effective to defer only Fees earned after the date the form is received by the Bank.
2.02    Deferral Changes
The Director may modify the amount of Fees to be deferred by filing a subsequent signed Deferral Election Form with the Bank and obtaining written approval by the Board of Directors.  The modified deferral shall not be effective until the calendar year following the year in which the subsequent Election Form is received by the Bank.  Notwithstanding anything to the contrary, in no event shall written approval be given by the Board of Directors unless explicitly permitted by applicable law, including but not limited to, Code section 409A.
ARTICLE III.  DEFERRAL ACCOUNT
3.01    Establishing and Crediting
The Bank shall establish a Deferral Account on its books for the Director and shall credit to the Deferral Account the following amounts:
		
	A.
	Deferrals

The Fees deferred by the Director as of the time the Fees would have otherwise been paid to the Director.

3

		
	B.
	Interest

On a monthly basis, under this Agreement and immediately following the payment of any benefits or deferrals, as long as a balance exists, unless otherwise stated, interest is to be credited on the account balance since the preceding credit under this Section, if any, equal to the rate determined by the Bank’s Board of Directors, in its sole discretion.  
3.02    Statement of Accounts
The Bank shall provide to the Director with a statement setting forth the Director’s Deferral Account balance within one hundred twenty (120) days after the end of each calendar year.
3.03    Accounting Device Only
The Deferral Account is solely a device for measuring amounts to be paid under this Agreement.  The Deferral Account is not a segregated fund of any kind.  The Director is a general unsecured creditor of the Bank for the payment of benefits.  The benefits represent the mere Bank promise to pay such benefits.  The Director’s rights are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by the Director’s creditors.
ARTICLE IV.  DISTRIBUTION OF BENEFITS
4.01    Distribution Election
The Director may make an distribution election under this Agreement by filing with the Bank a signed Distribution Election Form within thirty (30) days after the date of this Agreement. 
		
	A.
	The Director may elect to have benefits payable on death, Disability or Termination of Service, to be paid in a lump sum or in annual installments over five or ten years.  In the absence of an election, payment shall be made in a lump sum. 

		
	B.
	The Director may also elect to have his account balance paid out in the event of a Change In Control, in a lump sum or in annual installments over five or ten years.   

		
	C.
	The Director’s distribution election shall apply to all future deferrals and benefits.  Distribution elections shall become irrevocable after the initial Election Date and may only be changed as permitted in Section 4.02 below.  If no Distribution Election Form is completed and returned on or before the initial Election Date, the Director’s account balance shall be paid in a lump sum on the earliest of the Director’s death, Disability or Termination of Service (subject to the Director’s permitted changes in the form and timing of payment described in Section 4.02 below).  

4

4.02    Changes to Distribution Election
The Director may not change the form of benefit payment initially elected under Section 4.01 unless the change is approved by the Board of Directors and the change satisfies the following requirements:
		
	i.
	The modified election shall not be effective until twelve (12) months after the date made;

		
	ii.
	For payments beginning as a result of the Director’s Termination from Service, payments beginning at a fixed time or on a fixed schedule, or payments due as a result of a Change in Control, the first payment due under the modified election must be deferred for a period of at least five (5) years from the date such payment would have been made in the absence of the modified election; and

		
	iii.
	With respect to payments beginning at a fixed time or on a fixed schedule, the Director must modify his Distribution Election at least twelve (12) months prior to the first scheduled payment due under this Agreement.  

Notwithstanding anything to the contrary, in no event shall written approval be given by the Board of Directors unless explicitly permitted by applicable law, including but not limited to, Code section 409A.
4.03    Benefits on Death
In the event of the Director’s death prior to payment of his Deferral Account, the balance remaining in his Deferral Account (if any) shall be paid to the Director’s designated beneficiary(ies) in a lump sum within sixty (60) days following the date of death.
4.04    Hardship Distribution
Upon the Bank’s determination (following petition by the Director) that the Director has suffered an Unforeseeable Emergency (defined below), the Bank may, in its sole discretion, make distributions from the Director’s Deferral Account.  Any distribution made pursuant to this provision must be made in accordance with Code section 409A, and must not exceed the amount reasonably necessary (including anticipated taxes on the distribution) to meet the emergency financial need and not reasonably available from other resources of the Director (including reimbursement or compensation by insurance, liquidation of the Director’s assets to the extent such liquidation itself would not cause severe financial hardship, or by cessation of deferrals under this Agreement), In making this determination, the Bank will take into account any such additional compensation that is available to the Director.  Any distribution under this provision shall be paid to the Director in a single lump sum as soon as administratively practicable following receipt of the appropriate forms and information required by and acceptable to the Bank.  Notwithstanding anything to the contrary, in the event a Director receives a distribution from the Agreement on account of an Unforeseeable Emergency, future deferrals under the Agreement will be cancelled for the remainder of the calendar year.  An “Unforeseeable Emergency” shall mean a severe financial hardship to the Director due to (a) uninsured medical expenses resulting from an illness or accident of the Director, the Director’s 

5

spouse, or a dependent of the Director (as defined in Code section 152(a) without regard to Code sections 152(b)(1), 152(b)(2) and 152(d)(1)(B)) of the Director; (b) an uninsured casualty loss pertaining to property owned by the Director; or, (c) other similar extraordinary and unforeseeable circumstances involving an uninsured loss arising as a result of an event beyond the control of the Director, provided however that any such event qualifies as an “unforeseeable emergency” within the meaning of Code section 409A.
4.05    Commencement of Distributions
Payments to the Director (or his Designated Beneficiary) shall begin as soon as practicable after the date of the Director’s Termination of Service, Disability, death, or a Change In Control (as applicable), but no later than ninety (90) days following one of these payment events.   
4.06    Medium of Payment
All distributions shall be paid in cash.
ARTICLE V.  RESTRICTIONS AND LIMITATIONS ON PAYMENT OF BENEFITS
5.01    Payment Restrictions
Notwithstanding any provisions of this Agreement to the contrary, if any “payment restrictions” (as hereinafter defined) restrict payment or require the recapture or “clawback” of any benefits received by the Director, the Bank shall not be obligated to pay and/or the Director shall be required to repay such amounts to the Bank no later than thirty (30) days following Director’s receipt of a written notice from the Bank indicating that benefits are subject to restrictions, recapture or clawback pursuant to the payment restrictions.  “Payment Restrictions” means any applicable state or federal statute, law, regulation, or regulatory interpretation or other guidance, or contractual arrangement with or required by a governmental authority that would restrict the Bank from paying benefits or require the Bank to seek or demand repayment or return of any benefits received by a Director for any reason, including, without limitation, FIL-66-02010 and any related or successor regulatory guidance, any regulatory or enforcement interpretations or guidance provided by the Securities Exchange Commission or other regulatory body under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Bank or its successors later obtaining information indicating that the Director has committed, is substantially responsible for, or has committed, the respective acts or omissions, conditions, or offenses outlined under 12 C.F.R. 359.4(a)(4).
Any benefit under this Agreement shall be subject to mandatory repayment by the Director to the extent the Director is, or in the future becomes, subject to (a) any Bank “clawback” or recoupment policy that is adopted to comply with the requirements of any applicable law, rule, regulation, or otherwise, or (b) any law, rule, or regulation which imposes mandatory recoupment, under circumstances set forth in such law, rule, or regulation.
To the extent that one or more exemptions are reasonably available to avoid Payment Restrictions and permit the payment of benefits to the Director, the Bank shall request exemption and permission 

6

to pay the benefits in good faith, and shall make all reasonable efforts to obtain an exemption and/or permission to pay the benefits in accordance with this Agreement.
5.02    Regulatory Compliance
The parties specifically acknowledge that while the restrictions contained in Section 131 of the Federal Deposit Insurance Corporation Improvement Act of 1991, relating to the payment of compensation for senior executive officers of institutions which are deemed “undercapitalized”, do not currently apply to the Bank such provisions may affect the crediting or payment of benefits if the Bank should be deemed undercapitalized by any state or federal regulatory authority (including, without limitation, the Federal Deposit Insurance Company and the Federal Reserve Board) in the future.  Without limiting the generality of the foregoing, under no circumstances will the Bank be required to pay benefits or take any other actions if such actions would result in any violation of applicable law, rule, regulation or regulatory directive.
ARTICLE VI.  RESTRICTIONS ON TRANSFER OF BENEFITS
6.01    No Control or Alienation
Except as provided in this Article, the Director has no control over benefits except according to his Deferral Election Form, his Distribution Election Form, and his Beneficiary Designation Form.  No right or benefit under this Agreement shall be subject to anticipation, alienation, sale, assignment, transfer, pledge, encumbrance or charge, and any attempt to do so shall be void.  No right or benefit hereunder shall in any manner be liable for or subject to the debts, contracts, liabilities, or torts of the person entitled to such benefit.
6.02    Assignment of Benefits in Connection with Separation or Divorce
All or a portion of the Director’s Deferral Account may be assigned and transferred to a spouse, former spouse or other dependent under the terms of a domestic relations order that meets the requirements set forth in Internal Revenue Code section 414(p)(1)(B).  The Bank shall determine, in its sole and absolute discretion, whether an assignment and transfer shall be made pursuant to the terms of a domestic relations order.  Upon assignment and transfer of all or any portion of a Director’s Deferral Account, the amount assigned and transferred shall be distributed to the spouse, former spouse or other dependent, in one lump sum payment, as soon as administratively feasible.  Any assignment, transfer or payment to a spouse, former spouse or other dependent made pursuant to the terms of a domestic relations order shall be charged against and reduce the Director’s Deferral Account balance.  The Bank shall not be liable in any manner to any person for complying with the terms of a domestic relations order.
ARTICLE VII.  BENEFICIARIES
7.01    Beneficiary Designations
The Director shall designate a beneficiary by filing a written designation with the Bank, using the Beneficiary Designation Form attached to this Agreement as Exhibit C.  The Director may revoke 

7

or modify the designation at any time by filing a new designation.  However, designations will only be effective if signed by the Director and accepted by the Bank during the Director’s lifetime.  The Director’s beneficiary designation shall be deemed automatically revoked if the beneficiary predeceases the Director, or if the Director names a spouse as beneficiary and the marriage is subsequently dissolved.  If the Director dies without a valid beneficiary designation, all payments shall be made to the Director’s surviving spouse, if any, and if none, to the Director’s surviving children and the descendants of any deceased child by right of representation, and if no children or descendants survive, to the Director’s estate.
7.02    Facility of Payment
If a benefit is payable to a minor, to a person declared incompetent, or to a person incapable of handling the disposition of his or her property, the Bank may pay such benefit to the guardian, legal representative or person having the care or custody of such minor, incompetent person or incapable person.  The Bank may require proof of incompetency, minority or guardianship as it may deem appropriate prior to distribution of the benefit.  Such distribution shall completely discharge the Bank from all liability with respect to such benefit.
ARTICLE VIII.  GENERAL LIMITATIONS
8.01    Insurance
The Bank may acquire an insurance policy on the life of the Director.  The Bank will be the owner and beneficiary of the policy.  The Director will have no interest in or right to the policy.
8.02    Suicide
The Bank shall not pay any benefit under this Agreement exceeding the Deferral Account if the Director commits suicide within three years after the date of this Agreement.  In addition, the Bank shall not pay any benefit under this Agreement if the Director has made any material misstatement of fact on a resume provided to the Bank, or on any application for any benefits provided by the Bank to the Director.
8.03    General
Notwithstanding anything to the contrary contained in this Agreement, the Director is entitled to only one benefit which shall be determined by the first event to occur which is dealt with by this Agreement.  Subsequent occurrence of events dealt with by this Agreement shall not entitle the Director or his or her beneficiaries to other or further benefits under this Agreement.
8.04    Tax Consequences
The Bank does not insure or guarantee the tax consequences of payments provided hereunder for matters beyond its control, and the Director certifies that his decision to reduce and defer to receive his compensation is not due to any reliance upon financial, tax of legal advice given by the Bank, and of its employees, agents, accountants or legal advisors.

8

8.05    Termination For Cause
Notwithstanding any provision of the Agreement to the contrary, the Bank shall not pay any benefit under the Agreement that is in excess of the Director’s Deferrals (i.e., the interest earned on the Deferred Account) if the Director’s Termination of Service results from Termination for Cause.  The Director’s Deferrals shall be paid to the Director in the manner otherwise provided in the Agreement.  No interest shall be credited on the Deferrals during any installment period.
8.06    Specified Employee Requirements

In the event that Director is also a Specified Employee (defined below) as of the date of Termination of Service, payments under the Agreement upon Termination of Service may not be made before the date that is six months after Termination of Service (or, if earlier than the end of the six-month period, the date of death of the Director).  Payments to which the Director would otherwise be entitled during the first six months following Termination of Service, but for this Six-Month Delay provision, shall be accumulated and paid on the first day of the seventh month following Termination of Service.
		
	B.
	Specified Employee

Director shall be deemed to be a “Specified Employee” if, as of the date of Director’s Termination of Service, Director is a Key Employee (defined below) of the Bank and the Bank has stock which is publicly traded on an established securities market or otherwise.
		
	C.
	Key Employee

If Director meets each of the requirements of Internal Revenue Code section 416(i)(l)(A)(i), (ii), or (iii) (applied in accordance with the regulations thereunder and disregarding section 416(i)(5)) at any time during a twelve (12) month period ending on December 31 (the “Specified Employee Identification Date”), then Director shall be treated as a Key Employee for the entire twelve month period beginning on the following April 1.  Such April 1 date shall be the “Specified Employee Effective Date” for purposes of Code section 409A.
ARTICLE IX.  CLAIMS AND REVIEW PROCEDURES
9.01    Claims Procedure
The Bank shall notify any person or entity that makes a claim for benefits under this Agreement (the “Claimant”) in writing, within ninety (90) days of Claimant’s written application for benefits, of his or her eligibility or noneligibility for benefits under the Agreement.  If the Bank determines that the Claimant is not eligible for benefits or full benefits, the notice shall set forth (a) the specific reasons for such denial, (b) a specific reference to the provisions of the Agreement on which the 

9

denial is based, (c) a description of any additional information or material necessary for the Claimant to perfect his or her claim, and a description of why it is needed, and (d) an explanation of the Agreement’s claims review procedure and other appropriate information as to the steps to be taken if the Claimant wishes to have the claim reviewed.  If the Bank determines that there are special circumstances requiring additional time to make a decision, the Bank shall notify the Claimant of the special circumstances and the date by which a decision is expected to be made, and may extend the time for up to an additional ninety (90) days.
9.02    Review Procedure
If the Claimant is determined by the Bank not to be eligible for benefits, or if the Claimant believes that he or she is entitled to greater or different benefits, the Claimant shall have the opportunity to have such claim reviewed by the Bank by filing a petition for review with the Bank within sixty (60) days after receipt of the notice issued by the Bank.  Said petition shall state the specific reasons, which the Claimant believes entitle him or her to benefits or to greater or different benefits.  Within sixty (60) days after receipt by the Bank of the petition, the Bank shall afford the Claimant (and counsel, if any) an opportunity to present his or her position to the Bank verbally or in writing, and the Claimant (or counsel) shall have the right to review the pertinent documents.  The Bank shall notify the Claimant of its decision in writing within the sixty (60) day period, stating specifically the basis of its decision, written in a manner to be understood by the Claimant and the specific provisions for the Agreement on which the decision is based.  If, because of the need for a hearing, the sixty (60) day period is not sufficient, the decision may be deferred for up to another sixty (60) days at the election of the Bank, but notice of this deferral shall be given to the Claimant.
ARTICLE X.  AMENDMENTS AND TERMINATION
The Bank may amend or terminate this Agreement at any time prior to the Director’s Termination of Service by written notice to the Director.  In no event shall this Agreement be terminated without payment to the Director of the Deferral Account balance attributable to the Director’s Deferrals and interest credited on such amounts unless the Agreement terminates as a result of Termination for Cause in which event the Director forfeits the interest credited on the Director’s Deferrals.
Notwithstanding the foregoing, the Bank’s discretionary termination of this Agreement shall not result in the acceleration of the time and form of payment to Director, except where the right to payment arises in connection with the Bank’s discretionary termination of the Agreement under one of the circumstances identified in Treasury Regulations §1.409A-3(j)(4)(ix).
ARTICLE XI.  MISCELLANEOUS

The rights to benefits are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors.  Any insurance on the Director’s life is a general asset of the Bank to which the Director and beneficiary have no preferred or secured claim.

DIRECTOR DEFERRED FEE AGREEMENT
Distribution Election Form
When you become eligible to defer Director Fees you may complete and return a Distribution Election Form on or before the date that your initial Deferral Election Form is due.  If you do not timely complete and return your Distribution Election Form, all Fees that you defer during your service with the Bank will be paid to you in a lump sum after your Termination of Service, Disability or death, unless you make a subsequent distribution election as permitted under the rules described below.
PLEASE CONSIDER YOUR DISTRIBUTION ELECTION CAREFULLY.  This election will determine how and when all Fees that you defer now and in the future will be paid.  Your initial election may be modified ONLY as permitted under the section titled SUBSEQUENT CHANGES TO YOUR DISTRIBUTION ELECTION below.

SUBSEQUENT CHANGES TO YOUR DISTRIBUTION ELECTION
The federal tax code strictly limits any future changes to your initial distribution election.  You may only change your distribution election in accordance with the following rules:
		
	1.
	Your subsequent election may not be effective until twelve (12) months after the date it is made; and

		
	2.
	For payments beginning as a result of Termination of Service or a Change In Control, the first payment due under the subsequent election may not be made for a period of at least five (5) years from the date the first payment would have been made under your prior distribution election.

For example, assume that your initial election is for a lump sum payment of your benefits following Termination of Service.  Any subsequent distribution election will only be valid if it is made at least twelve (12) months before your Termination of Service, and the payment under your modified election is not scheduled to be made earlier than the fifth anniversary of your Termination of Service.  If the subsequent distribution election does not meet these requirements, it will not be effective and your benefits will be paid according to your initial distribution election.
Your signature below confirms that you have received a copy of the Director Deferred Fee Agreement.  All terms used in this Distribution Election Form have the same meaning as given to those terms in the Agreement.
