 (REVERSE OF SECURITY) 

OCULAR THERAPEUTIX, INC. 

[ Title of Security ] 
  

	1.	Indenture 

 This Security is one of a duly authorized issue of debentures, notes or other
evidence of indebtedness (hereinafter called the “Securities”) of the Issuer of the series hereinafter specified, which series is initially limited in aggregate principal amount to
[$]        , all of such Securities issued and to be issued under an Indenture dated as of         ,
            (the “Indenture”) between the Issuer and
                                        as
trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as in effect on the date of the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by
applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. 

This Security is one of a series of Securities designated pursuant to the Indenture [and an [Supplemental Indenture] dated
            ,         , issued pursuant to Section 2.01 and Section 2.03 thereof (the “Supplement”)] as
                    . The Securities are general unsecured obligations of the Issuer. The Issuer may, subject to the provisions of the Indenture and
applicable law, issue additional Securities of any series under the Indenture. 
  

	2.	Method of Payment. 

 The Issuer shall pay interest on the Securities (except defaulted
interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record
Date and prior to such Interest Payment Date. Holders must surrender Securities to the Trustee to collect principal payments. The Issuer shall pay Principal and interest in money of [the United States] that at the time of payment is legal
tender for payment of public and private debts. [However, the payments of interest, and any portion of the Principal (other than interest payable at maturity or on any redemption or repayment date or the final payment of Principal) shall be made by
the Paying Agent, upon receipt from the Issuer of immediately available funds by             [a./p.m.], New York City time (or such other time as may be agreed to between the Issuer
and the Paying Agent or the Issuer), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the Trustee 15 days prior to such payment date requesting that such payment will be so made
and designating the bank account to which such payments shall be so made and in the case of payments of Principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating the same principal amount as the unredeemed
principal amount of the Securities surrendered.] 

	3.	Redemption. 

 [The Securities of this series may be redeemed at any time [on or
after             ,         ], as a whole or in part, at the option of the Issuer, upon mailing notice of such redemption not less than 30 and
not more than 60 days to the Holders of such Securities, at a redemption price equal to             .] 
  

	4.	Paying Agent and Security Registrar 

 Initially, the Trustee will act as Paying Agent and
Security Registrar. The Issuer may change any Paying Agent or Security Registrar without notice to the Holders. 
  

	5.	Denominations; Transfer; Exchange. 

 The Securities are in registered form, without
coupons, in denominations of [$1,000] and multiples of [$1,000]. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. [The Issuer need not register the transfer of or exchange
(a) any Securities for a period of fifteen (15) days preceding the first mailing of notice that such Securities are to be redeemed, or (b) any Securities selected, called or being called for redemption in whole or in part, except, in
the case of any Security to be redeemed in part, the portion thereof not to be so redeemed.] 
  

	6.	Persons Deemed Owners. 

 The registered Holder of a Security shall be treated as the owner of it
for all purposes. 
  

	7.	Unclaimed Funds. 

 If funds for the payment of principal or interest remain unclaimed for two
years, the Trustee and the Paying Agent will repay the funds to the Issuer. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease. 

 

	8.	Defeasance. 

 The Indenture [as amended by the Supplement] contains provisions for
defeasance at any time of (a) the entire indebtedness of the Issuer on this Security and (b) certain restrictive covenants and the related Events of Default, upon compliance by the Issuer with certain conditions set forth therein, which
provisions [apply] to this Security. 
  

	9.	Amendment; Supplement; Waiver. 

 Subject to certain exceptions, the Securities of this series,
[the Supplement] and the provisions of the Indenture relating to the Securities of this series may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities of this
series then outstanding, and any existing Default or Event of Default, other than the non-payment of the principal amount of or interest on the Securities of this series, or compliance with certain provisions may be waived with the consent of the
Holders of a majority in aggregate principal amount of all the Securities of this series, then outstanding. 

  
 5 

 
Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency,
provide for uncertificated Securities in addition to or in place of certificated Securities, or make any other change that does not adversely affect the rights of any Holder of a Security. 

 

	10.	Defaults and Remedies. 

 If an Event of Default (other than certain bankruptcy Events of
Default with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities of this series then outstanding (voting as a separate class) by notice in writing to the Issuer (and
also to the Trustee if such notice is given by the Holders) may declare [the entire principal] of the Securities of this series and the interest accrued thereon, if any, to be due and payable immediately in the manner and with the effect
provided in the Indenture. If a bankruptcy Event of Default with respect to the Issuer occurs and is continuing, then [the entire principal] of the Securities then outstanding and interest accrued thereon, if any, shall become due and payable
immediately in the manner and with the effect provided in the Indenture. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the
Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in
its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest. 

 

	11.	Subordination. 

 Reference is made to the Indenture, including, without limitation, provisions
subordinating the payment of principal of and premium, if any, and interest on the Securities to the prior payment in full of all Senior Indebtedness as defined in the Indenture. Such further provisions shall for all purposes have the same
effect as though fully set forth at this place. 
  

	12.	Trustee Dealings with Issuer. 

 The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal with the Issuer as if it were not the Trustee. 
  

	13.	No Recourse Against Others. 

 No stockholder, director, officer, employee or incorporator, past,
present or future as such, of the Issuer or any predecessor or successor corporation thereof shall have any liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations
or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 

  
 6 

	14.	Authentication. 

 This Security shall not be valid until the Trustee manually signs the
certificate of authentication on this Security. 
  

	15.	Abbreviations and Defined Terms. 

 Customary abbreviations may be used in the name of a Holder
of a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act). 
  

	16.	CUSIP Numbers. 

 Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance
may be placed only on the other identification numbers printed hereon. 
  

	17.	Governing Law. 

 The laws of the State of New York shall govern the Indenture and this Security
thereof, and for all purposes this Security shall be governed by and construed in accordance with the laws of such State without regard to any principle of conflict of laws that would require or permit the application of the laws of any other
jurisdiction, except as may otherwise be required by mandatory provisions of law.

 FBR Capital
Markets & Co. 
 1300 North 17th Street 

Suite 1400 
 North Arlington, Virginia 22209 

Ladies and Gentlemen: 
 Evoke Pharma, Inc., a
Delaware corporation (the “Company”), confirms its agreement (this “Agreement”) with FBR Capital Markets & Co. (“FBR”), as follows: 

1. Issuance and Sale of Shares. The Company agrees that, from time to time during the term of this Agreement, on the terms and subject
to the conditions set forth herein, it may issue and sell through FBR, shares (the “Placement Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), provided however,
that in no event shall the Company issue or sell through FBR such number of Placement Shares that (a) would cause the Company not to satisfy the eligibility requirements for use of Form S-3 (including instruction I.B.6 thereof),
(b) exceeds the number of shares of Common Stock registered on the effective Registration Statement (as defined below) pursuant to which the offering is being made, or (c) exceeds the number of authorized but unissued shares of Common
Stock (the lesser of (a), (b) and (c), the “Maximum Amount”). Notwithstanding anything to the contrary contained herein, the parties hereto agree that compliance with the limitations set forth in this Section 1 on
the number of Placement Shares issued and sold under this Agreement shall be the sole responsibility of the Company and that FBR shall have no obligation in connection with such compliance. The issuance and sale of Placement Shares through FBR will
be effected pursuant to the Registration Statement (as defined below), although nothing in this Agreement shall be construed as requiring the Company to use the Registration Statement to issue any Placement Shares. 

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder
(the “Securities Act”), with the Securities and Exchange Commission (the “Commission”), a registration statement on Form S-3 (File No. 333-200176), including a prospectus relating to certain securities,
including the Placement Shares, to be issued from time to time by the Company, and which incorporates by reference documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as
amended, and the rules and regulations thereunder (the “Exchange Act”). The Company has prepared a prospectus supplement to the prospectus included as part of such registration statement specifically relating to the Placement Shares
(the “Prospectus Supplement”). The Company will furnish to FBR, for use by FBR, copies of the prospectus included as part of such registration statement, as supplemented by the Prospectus Supplement, relating to the Placement
Shares. Except where the context otherwise requires, such 

 
registration statement, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently
filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part of such registration statement pursuant to Rule 430B of the Securities Act, is herein called the “Registration Statement.” The
prospectus relating to the Placement Shares, including all documents incorporated or deemed incorporated therein by reference to the extent such information has not been superseded or modified in accordance with Rule 412 under the Securities Act (as
qualified by Rule 430B(g) of the Securities Act), included in the Registration Statement, as it may be supplemented by the Prospectus Supplement, in the form in which such prospectus and/or Prospectus Supplement have most recently been filed by the
Company with the Commission pursuant to Rule 424(b) under the Securities Act, is herein called the “Prospectus.” Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be
deemed to refer to and include the documents incorporated or deemed incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration
Statement or the Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein (the “Incorporated Documents”). 

For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement thereto shall
be deemed to include the most recent copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval System, or if applicable, the Interactive Data Electronic Application system when used by the Commission
(collectively, “EDGAR”). 
 2. Placements. Each time that the Company wishes to issue and sell Placement Shares
hereunder (each, a “Placement”), it will notify FBR by email notice (or other method mutually agreed to in writing by the Parties) of the number of Placement Shares to be issued, the time period during which sales are requested to
be made, any limitation on the number of Placement Shares that may be sold in any one day and any minimum price below which sales may not be made (a “Placement Notice”), the form of which is attached hereto as Schedule 1. The
receipt of each such Placement Notice shall promptly be acknowledged by FBR by email confirmation to the Company. The Placement Notice shall originate from any of the individuals from the Company set forth on Schedule 3 (with a copy to each
of the other individuals from the Company listed on such schedule), and shall be addressed to each of the individuals from FBR set forth on Schedule 3, as such Schedule 3 may be amended from time to time. Provided that the Company is
otherwise in compliance with the terms of this Agreement, the Placement Notice shall be effective immediately upon receipt by FBR unless and until (i) FBR declines to accept the terms contained therein for any reason, in its sole discretion,
within three (3) business days from the time the Placement Notice was received, (ii) the entire amount of the Placement Shares thereunder has been sold, (iii) the Company suspends or terminates the Placement Notice or (iv) this
Agreement has been terminated under the provisions of Section 13. The amount of any discount, commission or other compensation to be paid by the Company to FBR in connection with the sale of the Placement Shares shall be calculated in
accordance with the terms set forth in Schedule 2. It is expressly acknowledged and agreed that neither the Company nor FBR will have any obligation whatsoever with respect to a Placement or any Placement Shares unless and until the Company
delivers a Placement Notice to FBR and FBR does not decline such Placement Notice pursuant to the terms set forth above, and then only upon the 

  
 2 

 
terms specified therein and herein. In the event of a conflict between the terms of Sections 2 or 3 of this Agreement and the terms of a Placement Notice, the terms of the Placement
Notice will control. 
 3. Sale of Placement Shares by FBR. 

a. Subject to the terms and conditions of this Agreement, for the period specified in a Placement Notice, FBR will use its commercially
reasonable efforts consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of such national securities exchange that the Company’s Common Stock is listed on (the
“Exchange”), to sell the Placement Shares up to the amount specified in, and otherwise in accordance with the terms of, such Placement Notice. FBR will provide written confirmation to the Company no later than the opening of the
Trading Day (as defined below) immediately following the Trading Day on which it has made sales of Placement Shares hereunder setting forth the number of Placement Shares sold on such day, the compensation payable by the Company to FBR pursuant to
Section 2 with respect to such sales, and the Net Proceeds (as defined below) payable to the Company, with an itemization of the deductions made by FBR (as set forth in Section 5(b)) from the gross proceeds that it receives
from such sales. Subject to the terms of a Placement Notice, FBR agrees that all sales of Placement Shares by FBR will be made only by methods permitted by law and deemed to be an “at the market offering” as defined in Rule 415 of the
Securities Act, including without limitation sales made directly on the Exchange, on any other existing trading market for the Common Stock or to or through a market maker. Subject to the terms of a Placement Notice, FBR may also sell Placement
Shares by any other method permitted by law, including but not limited to negotiated transactions, subject to the Company’s prior written approval. “Trading Day” means any day on which Common Stock is purchased and sold on the
Exchange. 
 b. During the term of this Agreement, neither FBR nor any of its affiliates or subsidiaries shall engage in (i) any short
sale of any security of the Company, (ii) any sale of any security of the Company that FBR does not own or any sale which is consummated by the delivery of a security of the Company borrowed by, or for the account of, FBR, or (iii) any
market making, bidding, purchasing, stabilization or other trading activity with regard to the Common Stock, or attempting to induce another person to do any of the foregoing, if such activity would be prohibited under Regulation M or other
anti-manipulation rules under the Securities Act. Neither FBR nor any of its affiliates or subsidiaries shall engage in any proprietary trading or trading for FBR’s (or its affiliates’ or subsidiaries’) own account. 

4. Suspension of Sales. The Company or FBR may, upon notice to the other party in writing (including by email correspondence to each of
the individuals of the other party set forth on Schedule 3, if receipt of such correspondence is actually acknowledged by any of the individuals to whom the notice is sent, other than via auto-reply) or by telephone (confirmed immediately by
verifiable facsimile transmission or email correspondence to each of the individuals of the other party set forth on Schedule 3), suspend any sale of Placement Shares; provided, however, that such suspension shall not affect or impair
any party’s obligations with respect to any Placement Shares sold hereunder prior to the receipt of such notice. Each of the parties agrees that no such notice under this Section 4 shall be effective against any other party unless
it is made to one of the individuals named on Schedule 3 hereto and acknowledged in accordance with the prior sentence, as such Schedule may be amended from time to time. 

  
 3 

 5. Sale and Delivery to FBR; Settlement. 

a. Sale of Placement Shares. The Company acknowledges and agrees that (i) there can be no assurance that FBR will be successful
in selling Placement Shares, (ii) FBR will incur no liability or obligation to the Company or any other person or entity if it does not sell Placement Shares for any reason other than a failure by FBR to use its commercially reasonable efforts
consistent with its normal trading and sales practices and applicable law and regulations to sell such Placement Shares as required under this Agreement and (iii) FBR shall be under no obligation to purchase Placement Shares on a principal
basis pursuant to this Agreement, except as otherwise agreed by FBR and the Company. 
 b. Settlement of Placement Shares. Unless
otherwise specified in the applicable Placement Notice, settlement for sales of Placement Shares will occur on the third (3rd) Trading Day (or such earlier day as is industry practice for
regular-way trading) following the date on which such sales are made (each, a “Settlement Date”). The amount of proceeds to be delivered to the Company on a Settlement Date against receipt of the Placement Shares sold (the
“Net Proceeds”) will be equal to the aggregate sales price received by FBR, after deduction for (i) FBR’s commission, discount or other compensation for such sales payable by the Company pursuant to Section 2
hereof, and (ii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales. 
 c.
Delivery of Placement Shares. On or before each Settlement Date, the Company will, or will cause its transfer agent to, electronically transfer the Placement Shares being sold by crediting FBR’s or its designee’s account (provided
FBR shall have given the Company written notice of such designee at least two Trading Days prior to the Settlement Date) at The Depository Trust Company through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may
be mutually agreed upon by the parties hereto which in all cases shall be freely tradable, transferable, registered shares in good deliverable form. On each Settlement Date, FBR will deliver the related Net Proceeds in same day funds to an account
designated by the Company on, or prior to, the Settlement Date. The Company agrees that if the Company, or its transfer agent (if applicable), defaults in its obligation to deliver Placement Shares on a Settlement Date, then in addition to and in no
way limiting the rights and obligations set forth in Section 11(a) hereto, it will (i) hold FBR harmless against any loss, claim, damage, or reasonable, documented expense (including reasonable and documented legal fees and
expenses), as incurred, arising out of or in connection with such default by the Company or its transfer agent (if applicable) and (ii) pay to FBR (without duplication) any commission, discount, or other compensation to which it would otherwise
have been entitled absent such default. 
 d. Limitations on Offering Size. Under no circumstances shall the Company cause or
request the offer or sale of any Placement Shares if, after giving effect to the sale of such Placement Shares, the aggregate number of Placement Shares sold pursuant to this Agreement would exceed the lesser of (A) together with all sales of
Placement Shares under this Agreement, the Maximum Amount, (B) the amount available for offer and sale under the currently effective Registration Statement and (C) the amount authorized from time to time to be issued and sold under this
Agreement by the Company’s board of directors, a duly authorized 

  
 4 

 
committee thereof or a duly authorized executive committee, and notified to FBR in writing. Under no circumstances shall the Company cause or request the offer or sale of any Placement Shares
pursuant to this Agreement at a price lower than the minimum price authorized from time to time by the Company’s board of directors, a duly authorized committee thereof or a duly authorized executive committee, and notified to FBR in writing.
Further, under no circumstances shall the Company cause or permit the aggregate offering amount of Placement Shares sold pursuant to this Agreement to exceed the Maximum Amount. 

6. Representations and Warranties of the Company. Except as disclosed in the Registration Statement or Prospectus (including the
Incorporated Documents), the Company represents and warrants to, and agrees with FBR that as of the date of this Agreement and as of each Applicable Time (as defined below), unless such representation, warranty or agreement specifies a different
date or time: 
 a. Registration Statement and Prospectus. The Company and, assuming no act or omission on the part of FBR that
would make such statement untrue, the transactions contemplated by this Agreement meet the requirements for and comply with the conditions for the use of Form S-3 under the Securities Act. The Registration Statement has been filed with the
Commission. The Prospectus will name FBR as the agent in the section entitled “Plan of Distribution.” The Company has not received, and has no notice of, any order of the Commission preventing or suspending the use of the Registration
Statement, or threatening or instituting proceedings for that purpose. The Registration Statement and the offer and sale of Placement Shares as contemplated hereby meet the requirements of Rule 415 under the Securities Act and comply in all material
respects with said Rule. Any statutes, regulations, contracts or other documents that are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement have been so described or
filed. Copies of the Registration Statement, the Prospectus, and any such amendments or supplements and all documents incorporated by reference therein that were filed with the Commission on or prior to the date of this Agreement have been
delivered, or are available through EDGAR, to FBR and its counsel. The Company has not distributed and, prior to the later to occur of each Settlement Date and completion of the distribution of the Placement Shares, will not distribute any offering
material in connection with the offering or sale of the Placement Shares other than the Registration Statement and the Prospectus and any Issuer Free Writing Prospectus (as defined below) to which FBR has consented, any such consent not to be
unreasonably withheld, conditioned or delayed. The Common Stock is currently quoted on the Exchange. The Company has not, in the 12 months preceding the date hereof, received notice from the Exchange to the effect that the Company is not in
compliance with the listing or maintenance requirements of the Exchange. The Company has no reason to believe that it will not in the foreseeable future continue to be in compliance with all such listing and maintenance requirements. 

b. No Misstatement or Omission. The Registration Statement, when it becomes effective, and the Prospectus, and any amendment or
supplement thereto, on the date of such Prospectus or amendment or supplement, conformed and will conform in all material respects with the requirements of the Securities Act. At each Settlement Date, the Registration Statement and the Prospectus,
as of such date, will conform in all material respects with the requirements of the Securities Act. The Registration Statement, when it became or becomes 

  
 5 

 
effective, did not, and will not, contain an 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 not
misleading. The Prospectus and any amendment and supplement thereto, on the date thereof and at each Applicable Time (defined below), did not or will not include an untrue statement of a material fact or omit to state a material fact necessary to
make the statements therein, in light of the circumstances under which they were made, not misleading. The documents incorporated by reference in the Prospectus or any Prospectus Supplement did not, and any further documents filed and incorporated
by reference therein will not, when filed with the Commission, contain an untrue statement of a material fact or omit to state a material fact required to be stated in such document or necessary to make the statements in such document, in light of
the circumstances under which they were made, not misleading. The foregoing shall not apply to statements in, or omissions from, any such document made in reliance upon, and in conformity with, information furnished to the Company by FBR
specifically for use in the preparation thereof. 
 c. Conformity with Securities Act and Exchange Act. The Registration Statement,
the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto, and the Incorporated Documents, when such documents were or are filed with the Commission under the Securities Act or the Exchange Act or became or become
effective under the Securities Act, as the case may be, conformed or will conform in all material respects with the requirements of the Securities Act and the Exchange Act, as applicable. 

d. Financial Information. The consolidated financial statements of the Company included or incorporated by reference in the
Registration Statement and the Prospectus, together with the related notes and schedules, present fairly, in all material respects, the consolidated financial position of the Company and the Subsidiaries (as defined below) as of the dates indicated
and the consolidated results of operations, cash flows and changes in stockholders’ equity of the Company for the periods specified and have been prepared in compliance with the requirements of the Securities Act and Exchange Act, as
applicable, and in conformity with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis (except for such adjustments to accounting standards and practices as are noted therein) during
the periods involved; the other financial and statistical data with respect to the Company and the Subsidiaries contained or incorporated by reference in the Registration Statement and the Prospectus, are accurately and fairly presented in all
material respects and prepared on a basis materially consistent with the financial statements and books and records of the Company; there are no financial statements (historical or pro forma) that are required to be included or incorporated by
reference in the Registration Statement, or the Prospectus that are not included or incorporated by reference as required; the Company and the Subsidiaries do not have any material liabilities or obligations, direct or contingent (including any off
balance sheet obligations), not described in the Registration Statement, and the Prospectus which are required to be described in the Registration Statement or Prospectus; and all disclosures contained or incorporated by reference in the
Registration Statement and the Prospectus, if any, regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the Commission) comply in all material respects with Regulation G of the Exchange Act and
Item 10 of Regulation S-K under the Securities Act, to the extent applicable.

 e. Conformity with EDGAR Filing. The Prospectus delivered to FBR for use in connection
with the sale of the Placement Shares pursuant to this Agreement will be identical to the versions of the Prospectus created to be transmitted to the Commission for filing via EDGAR, except to the extent permitted by Regulation S-T. 

f. Organization. The Company and any subsidiary that is a significant subsidiary (as such term is defined in Rule 1-02 of Regulation
S-X promulgated by the Commission) (each, a “Subsidiary”, and collectively, the “Subsidiaries”), are, and will be, duly organized, validly existing as a corporation and in good standing under the laws of their
respective jurisdictions of organization. The Company and the Subsidiaries are, and will be, duly licensed or qualified as a foreign corporation for transaction of business and in good standing under the laws of each other jurisdiction in which
their respective ownership or lease of property or the conduct of their respective businesses requires such license or qualification, and have all corporate power and authority necessary to own or hold their respective properties and to conduct
their respective businesses as described in the Registration Statement and the Prospectus, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, have a material
adverse effect or would reasonably be expected to have a material adverse effect on the assets, business, operations, earnings, properties, condition (financial or otherwise), prospects, stockholders’ equity or results of operations of the
Company and the Subsidiaries taken as a whole, or prevent the consummation of the transactions contemplated hereby (a “Material Adverse Effect”). 

g. Subsidiaries. As of the date hereof, the Company’s only Subsidiaries are set forth on Schedule 6(g). The Company owns
directly or indirectly, all of the equity interests of the Subsidiaries free and clear of any lien, charge, security interest, encumbrance, right of first refusal or other restriction, and all the equity interests of the Subsidiaries are validly
issued and are fully paid, nonassessable and free of preemptive and similar rights. 
 h. No Violation or Default. Neither the
Company nor any Subsidiary is (i) in violation of its charter or by-laws or similar organizational documents; (ii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such a default, in the
due performance or observance of any term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any Subsidiary is a party or by which the Company or any
Subsidiary is bound or to which any of the property or assets of the Company or any Subsidiary is subject; or (iii) in violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or
regulatory authority having jurisdiction over the Company, except, in the case of each of clauses (ii) and (iii) above, for any such violation or default that would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. To the Company’s knowledge, no other party under any material contract or other agreement to which it or any Subsidiary is a party is in default in any respect thereunder where such default would reasonably be expected
to have a Material Adverse Effect. 
 i. No Material Adverse Effect. Since the date of the most recent financial statements of the
Company included or incorporated by reference in the Registration Statement and Prospectus, there has not been (i) any Material Adverse Effect, (ii) other than this Agreement, any transaction which is material to the Company and the
Subsidiaries taken as a whole, (iii) any obligation or liability, direct or contingent (including any off-balance sheet 

  
 7 

 
obligations), incurred by the Company or the Subsidiaries, which is material to the Company and the Subsidiaries taken as a whole, (iv) any material change in the capital stock (other than
(A) the grant of additional options under the Company’s existing stock option plans or the issuance of additional Common stock pursuant to the Company’s employee stock purchase plan, (B) changes in the number of outstanding
Common Stock of the Company due to the issuance of shares upon the exercise or conversion of securities exercisable for, or convertible into, Common Stock outstanding on the date hereof, (C) as a result of the issuance of Placement Shares,
(D) any repurchases of capital stock of the Company, (E) as described in a proxy statement filed on Schedule 14A or a Registration Statement on Form S-4, or (F) otherwise publicly announced) or outstanding long-term indebtedness of
the Company or the Subsidiaries or (v) any dividend or distribution of any kind declared, paid or made on the capital stock of the Company or any Subsidiary, other than in each case above (A) in the ordinary course of business, (B) as
otherwise disclosed in the Registration Statement or Prospectus (including any document deemed incorporated by reference therein) or (C) where such matter, item, change, or development would not cause the statements in the Registration
Statement or the Prospectus to contain an 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 not misleading. 

j. Capitalization. The issued and outstanding shares of capital stock of the Company have been validly issued, are fully paid and
non-assessable and, other than as disclosed in the Registration Statement or the Prospectus, are not subject to any preemptive rights, rights of first refusal or similar rights. The Company has an authorized, issued and outstanding capitalization as
set forth in the Registration Statement and the Prospectus as of the dates referred to therein (other than (i) the grant of additional options or other equity awards under the Company’s existing stock option plans or the issuance of
additional Common Stock pursuant to the Company’s employee stock purchase plan, (ii) changes in the number of outstanding shares of Common Stock of the Company due to the issuance of shares upon the exercise or conversion of securities
exercisable for, or convertible into, Common Stock outstanding on the date hereof, (iii) as a result of the issuance of Placement Shares, or (iv) any repurchases of capital stock of the Company) and such authorized capital stock conforms
in all material respects to the description thereof set forth in the Registration Statement and the Prospectus. The description of the Common Stock in the Registration Statement and the Prospectus is complete and accurate in all material respects.
As of the date referred to therein, the Company did not have outstanding any options to purchase, or any rights or warrants to subscribe for, or any securities or obligations convertible into, or exchangeable for, or any contracts or commitments to
issue or sell, any shares of capital stock or other securities. 
 k. S-3 Eligibility. (i) At the time of filing the
Registration Statement and (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed
pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), the Company met the then applicable requirements for use of Form S-3 under the Securities Act, including compliance with General Instruction I.B.6 of Form S-3. As of
the close of trading on the Exchange on April 5, 2016, the aggregate market value of the outstanding voting and non-voting common equity (as defined in Rule 405) of the Company held by persons other than affiliates of the Company
(pursuant to Rule 144 of the Securities Act, those that directly, or indirectly through one or more intermediaries, control, or are controlled by, or are 

  
 8 

 
under common control with, the Company) (the “Non-Affiliate Shares”), was approximately $22.8 million (calculated by multiplying (x) the price at which the common
equity of the Company was last sold on the Exchange on April 5, 2016 times (y) the number of Non-Affiliate Shares). The Company is not a shell company (as defined in Rule 405) and has not been a shell company for at least 12 calendar
months previously and if it has been a shell company at any time previously, has filed current Form 10 information (as defined in Instruction I.B.6 of Form S-3) with the Commission at least 12 calendar months previously reflecting its status as an
entity that is not a shell company. 
 l. Authorization; Enforceability. The Company has full legal right, power and authority to
enter into this Agreement and, except as set forth in paragraph 6(n) hereof, perform the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Company and is a legal, valid and binding agreement of
the Company enforceable against the Company in accordance with its terms, except to the extent that (i) enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights
generally and by general equitable principles and (ii) the indemnification and contribution provisions of Section 11 hereof may be limited by federal or state securities laws and public policy considerations in respect thereof. 

m. Authorization of Placement Shares. The Placement Shares, when issued and delivered pursuant to the terms approved by the board of
directors of the Company or a duly authorized committee thereof, or a duly authorized executive committee, against payment therefor as provided herein, will be duly and validly authorized and issued and fully paid and nonassessable, free and clear
of any pledge, lien, encumbrance, security interest or other claim (other than any pledge, lien, encumbrance, security interest or other claim arising from an act or omission of FBR or a purchaser), including any statutory or contractual preemptive
rights, resale rights, rights of first refusal or other similar rights, and will be registered pursuant to Section 12 of the Exchange Act. The Placement Shares, when issued, will conform in all material respects to the description thereof set
forth in or incorporated into the Prospectus. 
 n. No Consents Required. No consent, approval, authorization, order, registration
or qualification of or with any court or arbitrator or any governmental or regulatory authority is required for the execution, delivery and performance by the Company of this Agreement, and the issuance and sale by the Company of the Placement
Shares as contemplated hereby, except for the registration of the Placement Shares under the Securities Act and pursuant to the Registration Statement and such consents, approvals, authorizations, orders and registrations or qualifications as may be
required under applicable state securities laws or by the by-laws and rules of the Financial Industry Regulatory Authority, Inc. (“FINRA”) or the Exchange, including any notices that may be required by the Exchange, in connection
with the sale of the Placement Shares by FBR. 
 o. No Preferential Rights. (i) No person, as such term is defined in Rule 1-02
of Regulation S-X promulgated under the Securities Act (each, a “Person”), has the right, contractual or otherwise, to cause the Company to issue or sell to such Person any Common Stock or shares of any other capital stock or other
securities of the Company (other than upon the exercise of options or warrants to purchase Common Stock, upon the exercise of options that may be granted from time to time under the Company’s stock option plans or pursuant to the

  
 9 

 
Company’s employee stock purchase plan), (ii) no Person has any preemptive rights, rights of first refusal, or any other rights (whether pursuant to a “poison pill” provision
or otherwise) to purchase any Common Stock or shares of any other capital stock or other securities of the Company from the Company which have not been duly waived with respect to the offering contemplated hereby, (iii) no Person has the right
to act as an underwriter or as a financial advisor to the Company in connection with the offer and sale of the Common Stock, and (iv) no Person has the right, contractual or otherwise, to require the Company to register under the Securities Act
any Common Stock or shares of any other capital stock or other securities of the Company, or to include any such shares or other securities in the Registration Statement or the offering contemplated thereby, whether as a result of the filing or
effectiveness of the Registration Statement or the sale of the Placement Shares as contemplated thereby or otherwise, except for such rights as have been waived or satisfied as of the date hereof. 

p. Independent Public Accountant. BDO USA, LLP (the “Accountant”), whose report on the consolidated financial
statements of the Company is filed with the Commission as part of the Company’s most recent Annual Report on Form 10-K filed with the Commission and incorporated into the Registration Statement, are and, during the periods covered by their
report, were independent public accountants within the meaning of the Securities Act and the Public Company Accounting Oversight Board (United States). To the Company’s knowledge, the Accountant is not in violation of the auditor independence
requirements of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) with respect to the Company. 
 q.
Enforceability of Agreements. To the Company’s knowledge, all agreements between the Company and third parties expressly referenced in the Prospectus, other than such agreements that have expired by their terms or whose termination is
disclosed in documents filed by the Company on EDGAR, are legal, valid and binding obligations of the Company enforceable against the Company in accordance with their respective terms, except to the extent that (i) enforceability may be limited
by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general equitable principles and (ii) the indemnification provisions of certain agreements may be limited by federal or
state securities laws or public policy considerations in respect thereof, and except for any unenforceability that, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. 

r. No Litigation. There are no legal, governmental or regulatory actions, suits or proceedings pending, nor, to the Company’s
knowledge, any legal, governmental or regulatory investigations, to which the Company or a Subsidiary is a party or to which any property of the Company or any Subsidiary is the subject that, individually or in the aggregate, if determined adversely
to the Company or any Subsidiary, would reasonably be expected to have a Material Adverse Effect or materially and adversely affect the ability of the Company to perform its obligations under this Agreement; to the Company’s knowledge, no such
actions, suits or proceedings are threatened or contemplated by any governmental or regulatory authority or threatened by others that, individually or in the aggregate, if determined adversely to the Company or any Subsidiary, would reasonably be
expected to have a Material Adverse Effect; and (i) there are no current or pending legal, governmental or regulatory actions, suits or proceedings, or, to the Company’s knowledge, investigations, that are required under the

  
 10 

 
Securities Act to be described in the Prospectus that are not described in the Prospectus including any Incorporated Document; and (ii) there are no contracts or other documents that are
required under the Securities Act to be filed as exhibits to the Registration Statement that are not so filed. 
 s. Licenses and
Permits. The Company and the Subsidiaries possess or have obtained, all licenses, certificates, consents, orders, approvals, permits and other authorizations issued by, and, to the Company’s knowledge, have made all declarations and filings
with, the appropriate federal, state, local or foreign governmental or regulatory authorities that are necessary for the ownership or lease of their respective properties or the conduct of their respective businesses as described in the Registration
Statement and the Prospectus (the “Permits”), except where the failure to possess, obtain or make the same would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Neither the Company
nor any Subsidiary have received written notice of any proceeding relating to revocation or modification of any such Permit or has any reason to believe that such Permit will not be renewed in the ordinary course, except where the failure to obtain
any such renewal would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 t. No
Material Defaults. Neither the Company nor any Subsidiary has defaulted on any installment on indebtedness for borrowed money or on any rental on one or more long-term leases, which defaults, individually or in the aggregate, would reasonably be
expected to have a Material Adverse Effect. The Company has not filed a report pursuant to Section 13(a) or 15(d) of the Exchange Act since the filing of its last Annual Report on Form 10-K, indicating that it (i) has failed to pay any
dividend or sinking fund installment on preferred stock or (ii) has defaulted on any installment on indebtedness for borrowed money or on any rental on one or more long-term leases, which defaults, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect. 
 u. Certain Market Activities. Neither the Company, nor any Subsidiary,
nor, to the Company’s knowledge, any of their respective directors, officers or controlling persons has taken, directly or indirectly, any action designed, or that has constituted or would reasonably be expected to cause or result in, under the
Exchange Act or otherwise, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Placement Shares. 

v. Broker/Dealer Relationships. Neither the Company nor any Subsidiary or any related entities (i) is required to register as a
“broker” or “dealer” in accordance with the provisions of the Exchange Act or (ii) directly or indirectly through one or more intermediaries, controls or is a “person associated with a member” or “associated

 x.
Taxes. The Company and the Subsidiaries have filed all federal, state, local and foreign tax returns which have been required to be filed and paid all taxes shown 

  
 11 

 
thereon through the date hereof, to the extent that such taxes have become due and are not being contested in good faith, except where the failure to do so would not reasonably be expected to
have a Material Adverse Effect. Except as otherwise disclosed in or contemplated by the Registration Statement or the Prospectus, no tax deficiency has been determined adversely to the Company or any Subsidiary which has had, or would reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect. The Company has no knowledge of any federal, state or other governmental tax deficiency, penalty or assessment which has been or might be asserted or threatened against
it which would reasonably be expected to have a Material Adverse Effect. 
 y. Title to Real and Personal Property. The Company and
the Subsidiaries have good and valid title in fee simple to all items of real property and good and valid title to all personal property (excluding Intellectual Property, which is discussed in Section 6(z) below) described in the Registration
Statement or Prospectus as being owned by them that are material to the businesses of the Company or such Subsidiary, in each case free and clear of all liens, encumbrances and claims, except for any failure to have good and marketable title for any
liens, encumbrances and claims that (i) do not materially interfere with the use made of such property by the Company and the Subsidiaries or (ii) would not reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect. Any real property described in the Registration Statement or Prospectus as being leased by the Company and the Subsidiaries is held by them under valid, existing and enforceable leases, except those that (A) do not materially
interfere with the use made of such property by the Company or the Subsidiaries or (B) would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect. 

z. Intellectual Property. The Company and the Subsidiaries own or possess or can acquire on reasonable terms enforceable rights to use
all patents, patent applications, trademarks (both registered and unregistered), service marks, trade names, trademark registrations, service mark registrations, copyrights, licenses and know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures) (collectively, the “Intellectual Property”), necessary for the conduct of their respective businesses as conducted as of the date hereof, except to the
extent that the failure to own or possess or acquire adequate rights to use such Intellectual Property would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; the Company and the Subsidiaries have not
received any written notice of any claim of infringement or conflict which asserted Intellectual Property rights of others, which infringement or conflict, if the subject of an unfavorable decision, would result in a Material Adverse Effect; there
are no pending, or to the Company’s knowledge, threatened judicial proceedings or interference proceedings against the Company or its Subsidiaries challenging the Company’s or any of its Subsidiary’s rights in or to or the validity of
the scope of any of the Company’s or any Subsidiary’s patents, patent applications or proprietary information, except such proceedings that have been disclosed in writing to FBR or would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect; no other entity or individual has any right or claim in any of the Company’s or any of its Subsidiary’s patents, patent applications or any patent to be issued therefrom by virtue of any
contract, license or other agreement entered into between such entity or individual and the Company or any Subsidiary or by any non-contractual obligation, other than by written licenses granted by the

  
 12 

 
Company or any Subsidiary except for such right or claim that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; the Company and the
Subsidiaries have not received any written notice of any claim challenging the rights of the Company or its Subsidiaries in or to any Intellectual Property owned, licensed or optioned by the Company or any Subsidiary which claim, if the subject of
an unfavorable decision would reasonably be expected to result in a Material Adverse Effect. 
 aa. Environmental Laws. The Company
and the Subsidiaries (i) are in compliance with any and all applicable federal, state, local and foreign laws, rules, regulations, decisions and orders relating to the protection of human health and safety, the environment or hazardous or toxic
substances or wastes, pollutants or contaminants (collectively, “Environmental Laws”); (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws
to conduct their respective businesses as described in the Registration Statement and the Prospectus; and (iii) have not received notice of any actual or potential liability for the investigation or remediation of any disposal or release of
hazardous or toxic substances or wastes, pollutants or contaminants, except, in the case of any of clauses (i), (ii) or (iii) above, for any such failure to comply or failure to receive required permits, licenses, other approvals or
liability as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 bb. Disclosure
Controls. The Company maintains systems of internal accounting controls designed to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations;
(ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general
or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company is not aware of any material
weaknesses in its internal control over financial reporting. Since the date of the latest audited financial statements of the Company included in the Prospectus, there has been no change in the Company’s internal control over financial
reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules
13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and the Subsidiaries is made known to the certifying officers by others within those entities,
particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the
Company’s controls and procedures as of a date within 90 days prior to the filing date of the Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the
fiscal year most recently ended the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the most recent Evaluation Date. Since the most recent Evaluation Date,
there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge, in other factors that could significantly
affect the Company’s internal controls. To the knowledge of the Company, the Company’s “internal controls over financial reporting” and “disclosure controls and procedures” are effective. 

  
 13 

 cc. Sarbanes-Oxley Act. There is and has been no failure on the part of the Company or,
to the knowledge of the Company, any of the Company’s directors or officers, in their capacities as such, to comply with any applicable provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated thereunder. Each of the
principal executive officer and the principal financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company as applicable) has made all certifications required
by Sections 302 and 906 of the Sarbanes-Oxley Act with respect to all reports, schedules, forms, statements and other documents required to be filed by the Company or furnished by it to the Commission during the past 12 months. For purposes of the

commissions or similar payments in connection with the transactions herein contemplated, except as may otherwise exist with respect to FBR pursuant to this Agreement. 

ee. Labor Disputes. No labor disturbance by or dispute with employees of the Company or any Subsidiary exists or, to the knowledge of
the Company, is threatened which would reasonably be expected to result in a Material Adverse Effect.

Neither the Company nor any Subsidiary is or, after giving effect to the offering and sale of the Placement Shares, will be an “investment company” or an entity “controlled” by an “investment company,” as such terms are
defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”).

governmental agency having jurisdiction over the Company (collectively, the “Money Laundering Laws”), except as would not reasonably be expected to result in a Material Adverse Effect; and no action, suit or proceeding by or before
any court or governmental agency, authority or body or any arbitrator involving the Company or any Subsidiary with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened. 

hh. Off-Balance Sheet Arrangements. There are no transactions, arrangements and other relationships between and/or among the Company,
and/or, to the knowledge of the Company, any of its affiliates and any unconsolidated entity, including, but not limited to, any structured finance, special purpose or limited purpose entity (each, an “Off Balance Sheet
Transaction”) that would reasonably be expected to affect materially the Company’s liquidity or the availability of or requirements for its capital resources, including those Off Balance Sheet Transactions described in the
Commission’s Statement about Management’s Discussion and Analysis of Financial Conditions and Results of Operations (Release Nos. 33-8056; 34-45321; FR-61), required to be described in the Registration Statement or the Prospectus which

 jj. ERISA. To the knowledge of the Company,
(i) each material employee benefit plan, within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), that is maintained, administered or contributed to by the Company or
any of its affiliates for employees or former employees of the Company and the Subsidiaries has been maintained in material compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not
limited to ERISA and the Internal Revenue Code of 1986, as amended (the “Code”); (ii) no prohibited transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred with respect to any

funding deficiency” as defined in Section 412 of the Code has been incurred, whether or not waived, and the fair market value of the assets of each such plan (excluding for these purposes accrued but unpaid contributions) equals or exceeds
the present value of all benefits accrued under such plan determined using reasonable actuarial assumptions, other than, in the case of (i), (ii) and (iii) above, as would not reasonably be expected to have a Material Adverse Effect. 

kk. Forward-Looking Statements. No forward-looking statement (within the meaning of Section 27A of the Securities Act and
Section 21E of the Exchange Act) (a “Forward-Looking Statement”) contained in the Registration Statement and the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.
The Forward-Looking Statements incorporated by reference in the Registration Statement and the Prospectus from the Company’s Annual Report on Form 10-K for the fiscal year most recently ended (i) except for any Forward-Looking Statement

(a) to fund or facilitate any activities or business of or with any Person or in any country or territory that, at the time of

(iii) The Entity represents and covenants that, except as detailed in the Prospectus, for the past 5 years, it has not

the Company in all material respects. 
 Any certificate signed by an officer of the Company and delivered to FBR or to counsel for FBR
pursuant to or in connection with this Agreement shall be deemed to be a representation and warranty by the Company, as applicable, to FBR as to the matters set forth therein. 

7. Covenants of the Company. The Company covenants and agrees with FBR that: 

a. Registration Statement Amendments. After the date of this Agreement and during any period in which a prospectus relating to any
Placement Shares is required to be delivered by FBR under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act) (the “Prospectus Delivery Period”)
(i) the Company will notify FBR promptly of the time when any subsequent amendment to the Registration Statement, other than documents incorporated by reference or amendments not related to any Placement, has been filed with the Commission
and/or has become effective or any subsequent supplement to the Prospectus has been filed and of any request by the Commission for any amendment or supplement to the Registration Statement or Prospectus related to the Placement or for additional
information related to the Placement, (ii) the Company will not file any amendment or supplement to the Registration Statement or Prospectus relating to the Placement Shares or a security convertible into the Placement Shares unless a copy
thereof has been submitted to FBR within a reasonable period of time before the filing and FBR has not reasonably objected thereto within the two (2) business day period (provided, however, that (A) the failure of FBR to make such
objection shall not relieve the Company of any obligation or liability hereunder, or affect FBR’s right to rely on the representations and warranties made by the Company in this Agreement and (B) the Company has no obligation to provide
FBR any advance copy of such filing or to provide FBR an opportunity to object to such filing if the filing does not name FBR or does not relate to a Placement; and provided, further, that the only remedy FBR shall have with respect to the failure
by the Company to obtain such consent shall be to cease making sales under this 

  
 19 

 
Agreement) and the Company will furnish to FBR at the time of filing thereof a copy of any document that upon filing is deemed to be incorporated by reference into the Registration Statement or
Prospectus, except for those documents available via EDGAR (regardless of whether the Company has requested confidential treatment therefor); and (iii) the Company will cause each amendment or supplement to the Prospectus to be filed with the
Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Securities Act or, in the case of any document to be incorporated therein by reference, to be filed with the Commission as required pursuant to the Exchange Act,
within the time period prescribed (the determination to file or not file any amendment or supplement with the Commission under this Section 7(a), based on the Company’s reasonable opinion or reasonable objections, shall be made
exclusively by the Company). 
 b. Notice of Commission Stop Orders. The Company will advise FBR, promptly after it receives notice
or obtains knowledge thereof, of the issuance or threatened issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of the suspension of the qualification of the Placement Shares for offering or sale
in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and it will promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order
should be issued. The Company will advise FBR promptly after it receives any request by the Commission for any amendments to the Registration Statement or any amendment or supplements to the Prospectus or any Issuer Free Writing Prospectus or for
additional information related to the offering of the Placement Shares or for additional information related to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus. 

c. Delivery of Prospectus; Subsequent Changes. During the Prospectus Delivery Period, the Company will use its commercially reasonable
efforts to comply in all material respects with all requirements imposed upon it by the Securities Act, as from time to time in force, and to file on or before their respective due dates all reports and any definitive proxy or information statements
required to be filed by the Company with the Commission pursuant to Sections 13(a), 13(c), 14, 15(d) or any other provision of or under the Exchange Act. If the Company has omitted any information from the Registration Statement pursuant to Rule
430A under the Securities Act, it will use its commercially reasonable efforts to comply with the provisions of and make all requisite filings with the Commission pursuant to said Rule 430A and to notify FBR promptly of all such filings. If during
the Prospectus Delivery Period any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances then existing, not misleading, or if during such Prospectus Delivery Period it is necessary to amend or supplement the Registration Statement or Prospectus to comply with the Securities Act, the Company will promptly
notify FBR to suspend the offering of Placement Shares during such period and the Company will promptly amend or supplement the Registration Statement or Prospectus (at the expense of the Company) so as to correct such statement or omission or
effect such compliance; provided, however, that the Company may delay the filing of any amendment or supplement, if in the judgment of the Company, it is in the best interest of the Company to do so. 

  
 20 

 d. Listing of Placement Shares. During the Prospectus Delivery Period, the Company will
use its commercially reasonable efforts to cause the Placement Shares to be listed on the Exchange and to qualify the Placement Shares for sale under the securities laws of such jurisdictions in the United States as FBR reasonably designates and to
continue such qualifications in effect so long as required for the distribution of the Placement Shares; provided, however, that the Company shall not be required in connection therewith to qualify as a foreign corporation or dealer in
securities or file a general consent to service of process in any jurisdiction. 
 e. Delivery of Registration Statement and
Prospectus. The Company will furnish to FBR and its counsel (at the reasonable expense of the Company) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein) and all amendments and
supplements to the Registration Statement or Prospectus that are filed with the Commission during the Prospectus Delivery Period (including all documents filed with the Commission during such period that are deemed to be incorporated by reference
therein), in each case as soon as reasonably practicable and in such quantities as FBR may from time to time reasonably request and, at FBR’s reasonable request, will also furnish copies of the Prospectus to each exchange or market on which
sales of the Placement Shares may be made; provided, however, that the Company shall not be required to furnish any document (other than the Prospectus) to FBR to the extent such document is available on EDGAR. 

f. Earnings Statement. The Company will make generally available to its security holders as soon as practicable, but in any event not
later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement covering a 12-month period that satisfies the provisions of Section 11(a) and Rule 158 of the Securities Act. 

g. Use of Proceeds. The Company will use the Net Proceeds as described in the Prospectus in the section entitled “Use of
Proceeds.” 
 h. Notice of Other Sales. Without the prior written consent of FBR, the Company will not, directly or indirectly,
offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Common Stock (other than the Placement Shares offered pursuant to this Agreement) or securities convertible into or exchangeable for Common Stock, warrants
or any rights to purchase or acquire, Common Stock during the period beginning on the date on which any Placement Notice is delivered to FBR hereunder and ending on the third (3rd) Trading Day immediately following the final Settlement Date
with respect to Placement Shares sold pursuant to such Placement Notice (or, if the Placement Notice has been terminated or suspended prior to the sale of all Placement Shares covered by a Placement Notice, the date of such suspension or
termination); and will not directly or indirectly in any other “at the market” or continuous equity transaction offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Common Stock (other than the
Placement Shares offered pursuant to this Agreement) or securities convertible into or exchangeable for Common Stock, warrants or any rights to purchase or acquire, Common Stock prior to the termination of this Agreement; provided, however,
that such restrictions will not be required in connection with the Company’s issuance or sale of (i) Common Stock, options to purchase Common Stock or Common Stock issuable upon the exercise of options, pursuant to any employee or director
stock option or benefits plan, stock ownership plan, employee stock purchase plan or dividend reinvestment plan (but not Common Stock subject to a waiver to exceed plan limits in its 

  
 21 

 
dividend reinvestment plan) of the Company whether now in effect or hereafter implemented; (ii) Common Stock issuable upon conversion of securities or the exercise of warrants, options or
other rights in effect or outstanding, and disclosed in filings by the Company available on EDGAR or otherwise in writing to FBR, and (iii) Common Stock, or securities convertible into or exercisable for Common Stock, offered and sold in a
privately negotiated transaction to vendors, customers, strategic partners or potential strategic partners or other investors conducted in a manner so as not to be integrated with the offering of Common Stock hereby. 

i. Change of Circumstances. The Company will, at any time during the pendency of a Placement Notice advise FBR promptly after it shall
have received notice or obtained knowledge thereof, of any information or fact that would alter or affect in any material respect any opinion, certificate, letter or other document required to be provided to FBR pursuant to this Agreement. 

j. Due Diligence Cooperation. During the term of this Agreement, the Company will cooperate with any reasonable due diligence review
conducted by FBR or its representatives in connection with the transactions contemplated hereby, including, without limitation, providing information and making available documents and senior corporate officers, during regular business hours and at
the Company’s principal offices, as FBR may reasonably request. 
 k. Required Filings Relating to Placement of Placement
Shares. To the extent that the filing of a prospectus supplement with the Commission with respect to a placement of Placement Shares becomes required under Rule 424(b) under the Securities Act, the Company agrees that on such dates as the
Securities Act shall require, the Company will (i) file a prospectus supplement with the Commission under the applicable paragraph of Rule 424(b) under the Securities Act (the date of each and every filing under Rule 424(b), a “Filing
Date”), which prospectus supplement will set forth, within the relevant period, the amount of Placement Shares to be sold through FBR, the Net Proceeds to the Company and the compensation payable by the Company to FBR with respect to such
Placement Shares, and (ii) deliver such number of copies of each such prospectus supplement to each exchange or market on which such sales were effected as may be required by the rules or regulations of such exchange or market. 

l. Representation Dates; Certificate. Each time during the term of this Agreement that the Company: 

(i) amends or supplements (other than a prospectus supplement relating solely to an offering of securities other than the
Placement Shares) the Registration Statement or the Prospectus relating to the Placement Shares by means of a post-effective amendment, sticker, or supplement but not by means of incorporation of documents by reference into the Registration
Statement or the Prospectus relating to the Placement Shares; 
 (ii) files an annual report on Form 10-K under the Exchange
Act (including any Form 10-K/A containing amended financial information or a material amendment to the previously filed Form 10-K); 

(iii) files its quarterly reports on Form 10-Q under the Exchange Act; or 

  
 22 

 (iv) files a current report on Form 8-K containing amended financial information
(other than information “furnished” pursuant to Items 2.02 or 7.01 of Form 8-K or to provide disclosure pursuant to Item 8.01 of Form 8-K relating to the reclassification of certain properties as discontinued operations in accordance
with Statement of Financial Accounting Standards No. 144) under the Exchange Act; 
 (Each date of filing of one or more of the
documents referred to in clauses (i) through (iv) shall be a “Representation Date.”) 
 the Company shall furnish FBR (but in the
case of clause (iv) above only if FBR reasonably determines that the information contained in such Form 8-K is material) with a certificate, in the form attached hereto as Exhibit 7(1). The requirement to provide a certificate under this
Section 7(1) shall be waived for any Representation Date occurring at a time at which no Placement Notice is pending, which waiver shall continue until the earlier to occur of the date the Company delivers a Placement Notice hereunder
(which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date on which the Company files its annual report on Form 10-K. Notwithstanding the foregoing, (i) upon the delivery of the first
Placement Notice hereunder and (ii) if the Company subsequently decides to sell Placement Shares following a Representation Date when the Company relied on such waiver and did not provide FBR with a certificate under this
Section 7(1), then before FBR sells any Placement Shares, the Company shall provide FBR with a certificate, in the form attached hereto as Exhibit 7(1), dated the date of the Placement Notice. 

m. Negative Assurance Letter. Within five (5) Trading Days of each Representation Date with respect to which the Company is
obligated to deliver a certificate in the form attached hereto as Exhibit 7(l) for which no waiver is applicable, and not more than once per calendar quarter, the Company shall cause to be furnished to FBR a written negative assurance letter of
Latham & Watkins LLP (“Company Counsel”), modified, as necessary, to relate to the Registration Statement and the Prospectus as then amended or supplemented; provided that, in lieu of such negative assurance letter
for subsequent periodic filings under the Exchange Act, counsel may furnish FBR with a letter (a “Reliance Letter”) to the effect that FBR may rely on the negative assurance letter previously delivered under this Section 7(m)
to the same extent as if it were dated the date of such letter (except that statements in such prior letter shall be deemed to relate to the Registration Statement and the Prospectus as amended or supplemented as of the date of the Reliance Letter).

 n. Comfort Letter. Within five (5) Trading Days after each Representation Date, except for such Representation Dates arising
pursuant to Section 7(l)(iii), the Company shall cause its independent accountants to furnish FBR a letter (the “Comfort Letter”), dated the date the Comfort Letter is delivered, which shall meet the requirements set
forth in this Section 7(n); provided, that if requested by FBR, the Company shall cause a Comfort Letter to be furnished to FBR within ten (10) Trading Days of such request following the date of occurrence of any restatement of the
Company’s financial statements. The Comfort Letter from the Company’s independent accountants shall be in a form and substance reasonably satisfactory to FBR, (i) confirming that they are an independent public accounting firm within
the meaning of the Securities Act and the PCAOB, (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by

  
 23 

 
accountants’ “comfort letters” to underwriters in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”) and
(iii) updating the Initial Comfort Letter with any information that would have been included in the Initial Comfort Letter had it been given on such date and modified as necessary to relate to the Registration Statement and the Prospectus, as
amended and supplemented to the date of such letter. 
 o. Market Activities. The Company will not, directly or indirectly,
(i) take any action designed to cause or result in, or that constitutes or would reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of Common
Stock or (ii) sell, bid for, or purchase Common Stock in violation of Regulation M, or pay anyone any compensation for soliciting purchases of the Placement Shares other than FBR. 

p. Investment Company Act. The Company will conduct its affairs in such a manner so as to reasonably ensure that neither it nor the
Subsidiaries will be or become, at any time prior to the termination of this Agreement, an “investment company,” as such term is defined in the Investment Company Act. 

q. No Offer to Sell. Other than an Issuer Free Writing Prospectus approved in advance by the Company and FBR in its capacity as agent
hereunder pursuant to Section 23, neither FBR nor the Company (including its agents and representatives, other than FBR in their capacity as such) will make, use, prepare, authorize, approve or refer to any written communication (as
defined in Rule 405), required to be filed with the Commission, that constitutes an offer to sell or solicitation of an offer to buy Placement Shares hereunder. 

r. Sarbanes-Oxley Act. The Company will use commercially reasonable efforts to maintain and keep accurate books and records reflecting
its assets and maintain internal accounting controls in a manner designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and
including those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company, (ii) provide reasonable
assurance that transactions are recorded as necessary to permit the preparation of the Company’s consolidated financial statements in accordance with GAAP, (iii) that receipts and expenditures of the Company are being made only in
accordance with management’s and the Company’s directors’ authorization, and (iv) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets
that could have a material effect on its financial statements. The Company will use commercially reasonable efforts to maintain such controls and other procedures, including, without limitation, those required by Sections 302 and 906 of the
Sarbanes-Oxley Act, and the applicable regulations thereunder that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and
reported, within the time periods specified in the Commission’s rules and forms, including, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or
submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow

  
 24 

 
timely decisions regarding required disclosure and to ensure that material information relating to the Company or the Subsidiaries is made known to them by others within those entities,
particularly during the period in which such periodic reports are being prepared. 
 8. Representations and Covenants of FBR. FBR
represents and warrants that it is duly registered as a broker-dealer under FINRA, the Exchange Act and the applicable statutes and regulations of each state in which the Placement Shares will be offered and sold, except such states in which FBR is
exempt from registration or such registration is not otherwise required. FBR shall continue, for the term of this Agreement, to be duly registered as a broker-dealer under FINRA, the Exchange Act and the applicable statutes and regulations of each

order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) receipt by the Company of any notification with respect to the suspension of the qualification or exemption from

 11. Indemnification and Contribution. 

(a) Company Indemnification. The Company agrees to indemnify and hold harmless FBR, its partners, members, directors, officers,
employees and agents and each person, if any, who controls FBR within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows: 

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, arising out of or based upon
any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to
make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or
the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; 

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, to the extent of the aggregate
amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue
statement or omission; provided that (subject to Section 11(d) below) any such settlement is effected with the written consent of the Company, which consent shall not unreasonably be delayed or withheld; and 

(iii) against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel), reasonably incurred
in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such
alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above, 
 provided, however, that
this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue 

  
 27 

 
statement or omission made solely in reliance upon and in conformity with written information furnished to the Company by FBR expressly for use in the Registration Statement (or any amendment
thereto), or in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto). 
 (b) FBR
Indemnification. FBR agrees to indemnify and hold harmless the Company and its directors and each officer of the Company who signed the Registration Statement, and each person, if any, who (i) controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act or (ii) is controlled by or is under common control with the Company against any and all loss, liability, claim, damage and expense whatsoever, as incurred, described
in the indemnity contained in Section 11(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or in any
related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information relating to FBR and furnished to the Company in writing by FBR expressly for use therein. 

(c) Procedure. Any party that proposes to assert the right to be indemnified under this Section 11 will, promptly after
receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 11, notify each such indemnifying party of the commencement of such
action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this
Section 11 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 11 unless, and only to the extent that, such omission results in the forfeiture of substantive
rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that
it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the
action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party
for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own
counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the
indemnifying party, (2) the indemnified party has reasonably concluded (based on written advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available
to the indemnifying party, (3) a conflict or potential conflict exists (based on written advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have
the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the
commencement of the action, in each of 

  
 28 

 
which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties
shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time
for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly after the indemnifying party receives a written invoice relating to fees, disbursements and other charges
in reasonable detail. An indemnifying party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent of each indemnified party,
settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 11 (whether or not any indemnified party is a party thereto),
unless such settlement, compromise or consent (1) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (2) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
 (d) Contribution. In order to
provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 11 is applicable in accordance with its terms but for any reason is held to be unavailable
from the Company or FBR, the Company and FBR will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than FBR, such as persons who control the Company within the meaning of the Securities Act or the
Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and FBR may be subject in such proportion as shall be appropriate to reflect the
relative benefits received by the Company on the one hand and FBR on the other hand. The relative benefits received by the Company on the one hand and FBR on the other hand shall be deemed to be in the same proportion as the total Net Proceeds from
the sale of the Placement Shares (net of commissions to FBR but before deducting expenses) received by the Company bear to the total compensation received by FBR (before deducting expenses) from the sale of Placement Shares on behalf of the Company.
If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault of the Company, on the one hand, and FBR, on the other hand, with respect to the statements or omission that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as
well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the Company or FBR, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and
FBR agree that it would not be just and equitable if contributions pursuant to this Section 11(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable
considerations referred to herein. The amount paid or 

  
 29 

 
payable by an indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section 11(d) shall be deemed to
include, for the purpose of this Section 11(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with
Section 11(c) hereof. Notwithstanding the foregoing provisions of this Section 11(d), FBR shall not be required to contribute any amount in excess of the commissions received by it under this Agreement and no person found
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this
Section 11(d), any person who controls a party to this Agreement within the meaning of the Securities Act or the Exchange Act, and any officers, directors, partners, employees or agents of FBR, will have the same rights to contribution
as that party, and each officer and director of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly
after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 11(d), will notify any such party or parties from whom contribution may be sought, but
the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 11(d) except to the extent that the failure to so notify such other
party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section 11(c) hereof, no party will be liable for
contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section 11(c) hereof. 

12. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in Section 11 of this
Agreement and all representations and warranties of the Company and FBR herein or in certificates delivered pursuant hereto shall survive, as of their respective dates, regardless of (i) any investigation made by or on behalf of FBR, any
controlling persons, or the Company (or any of their respective officers, directors or controlling persons), (ii) delivery and acceptance of the Placement Shares and payment therefor or (iii) any termination of this Agreement. 

13. Termination. 
 a.
FBR may terminate this Agreement, by notice to the Company, as hereinafter specified at any time (1) if there has been, since the time of execution of this Agreement or since the date as of which information is given in the Prospectus, any
Material Adverse Effect, or any development has occurred and that is reasonably likely to have a Material Adverse Effect or, in the reasonable judgment of FBR, is material and adverse and makes it impractical or inadvisable to market the Placement
Shares or to enforce contracts for the sale of the Placement Shares, (2) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or
escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the
reasonable judgment of FBR, impracticable or inadvisable to market the Placement Shares or to enforce contracts for the sale of the Placement Shares, (3) if trading in the Common Stock has been suspended or limited

  
 30 

 
by the Commission or the Exchange, or if trading generally on the Exchange has been suspended or limited, or minimum prices for trading have been fixed on the Exchange, (4) if any suspension
of trading of any securities of the Company on any exchange or in the over-the-counter market shall have occurred and be continuing, (5) if a major disruption of securities settlements or clearance services in the United States shall have
occurred and be continuing, or (6) if a banking moratorium has been declared by either U.S. Federal or New York authorities. Any such termination shall be without liability of any party to any other party except that the provisions of
Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury
Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination. If FBR elects to terminate this Agreement as provided in this Section 13(a), FBR shall provide the
required notice as specified in Section 14 (Notices). 
 b. The Company shall have the right, by giving ten (10) days notice as
hereinafter specified to terminate this Agreement in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of
Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury
Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination. 

c. FBR shall have the right, by giving ten (10) days notice as hereinafter specified to terminate this Agreement in its sole discretion
at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and
Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force
and effect notwithstanding such termination. 
 d. Unless earlier terminated pursuant to this Section 13, this Agreement shall
automatically terminate upon the issuance and sale of all of the Placement Shares through FBR on the terms and subject to the conditions set forth herein except that the provisions of Section 9 (Payment of Expenses),
Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to
Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination. 
 e. This Agreement shall remain in full
force and effect unless terminated pursuant to Sections 13(a), (b), (c), or (d) above or otherwise by mutual agreement of the parties; provided, however, that any such termination by mutual agreement shall in all
cases be deemed to provide that Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing
Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) shall remain in full force and effect. Upon termination of this Agreement, the Company shall not have any liability to FBR for any discount, commission or other
compensation with respect to any Placement Shares not otherwise sold by FBR under this Agreement. 

  
 31 

 f. Any termination of this Agreement shall be effective on the date specified in such notice of
termination; provided, however, that such termination shall not be effective until the close of business on the date of receipt of such notice by FBR or the Company, as the case may be. If such termination shall occur prior to the Settlement
Date for any sale of Placement Shares, such Placement Shares shall settle in accordance with the provisions of this Agreement.

Placement Shares that would constitute an Issuer Free Writing

contemplated by this Agreement and the process leading to such transactions, and no fiduciary or advisory relationship between the Company or any of its respective affiliates, stockholders (or other equity holders), creditors or employees or any
other party, on the one hand, and FBR, on the other hand, has been or will be created in respect of any of the transactions contemplated by this Agreement, irrespective of whether or not FBR has advised or is advising the Company on other matters,

b. it is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions
contemplated by this Agreement; 
 c. FBR has not provided any legal, accounting, regulatory or tax advice with respect to the transactions
contemplated by this Agreement and it has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate; 

d. it is aware that FBR and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of
the Company and FBR has no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship or otherwise; and 

e. it waives, to the fullest extent permitted by law, any claims it may have against FBR for breach of fiduciary duty or alleged breach of
fiduciary duty in connection with the sale of Placement Shares under this Agreement and agrees that FBR shall not have any liability (whether direct or indirect, in contract, tort or otherwise) to it in respect of such a fiduciary duty claim or to
any person asserting a fiduciary duty claim on its behalf or in right of it or the Company, employees or creditors of Company, other than in respect of FBR’s obligations under this Agreement and to keep information provided by the Company to
FBR and FBR’s counsel confidential to the extent not otherwise publicly-available.
