 Merriman Capital, Inc. (the
“Independent Underwriter”) 
 As Qualified Independent Underwriter 

Ladies and Gentlemen: 
 B. Riley Financial,
Inc., a Delaware corporation (the “Company”), proposes to issue and sell to purchasers (“Purchasers”), with the assistance of B. Riley & Co., LLC (when used herein in the singular, the
“Underwriter”, and together with the Independent Underwriter, the “Underwriters”) as agent of the Company, on a best efforts basis, pursuant to the terms of this Underwriting Agreement (this
“Agreement”) and, in the judgment of the Underwriter if deemed necessary, the Subscription Agreements in a form to be agreed (the “Subscription Agreements”), an aggregate of 2,105,200 shares (the “Firm
Shares”) of common stock, $0.0001 par value per share (the “Common Stock”), of the Company. In addition, the Company proposes to grant to the Underwriter the option to sell, as agent of the Company, up to an additional
315,780 shares of Common Stock (the “Additional Shares”). The Firm Shares and, if and to the extent such option is exercised, the Additional Shares are hereinafter collectively referred to as the “Shares.” The
Shares are described in the Prospectus referred to below. 
 The Company hereby confirms its engagement of the Merriman Capital, Inc., and
Merriman Capital, Inc. hereby confirms its agreement with the Company, to render services as a “qualified independent underwriter” within the meaning of Rule 5121 of the Financial Industry Regulatory Authority, Inc.
(“FINRA”) with respect to the offering and sale of the Shares. Merriman Capital, Inc., in its capacity as qualified independent underwriter, is referred to herein as the “Independent Underwriter.” 

As part of the transactions described under the heading “Proposed Acquisition of United Online, Inc.” in the General Disclosure
Package (as defined below), pursuant to an Agreement and Plan of Merger (“Merger Agreement”), dated as of May 4, 2016, among the Company, Unify Merger Sub, Inc., a wholly-owned subsidiary of the Company, and United Online, Inc.
(“Target”), Merger Sub will merger with and into Target, with Target surviving as a wholly-owned subsidiary of the Company. 

The Company, the Underwriter and the Independent Underwriter agree as follows: 







 1.     The Offering. On the basis of the representations,
warranties and agreements herein contained, and subject to the terms and conditions of this Agreement, the Company hereby appoints the Underwriter as its sole and exclusive agent for the purpose of selling, in accordance with the terms and
conditions hereof, the Firm Shares. The Underwriter hereby accepts such agency and agree to use its best efforts to sell the Firm Shares on said terms and conditions. All Firm Shares to be offered and sold in the Offering shall be sold through
the Underwriter, as agent for the Company, and the Underwriter agrees to use its best efforts to sell the Firm Shares as agent for the Company, at the price per share set forth in Schedule A hereto. In consideration for the
Underwriter’s efforts under this Section, the Company agrees to pay the Underwriter the commission (the “Selling Commission”) set forth in Schedule A hereto. The Underwriter may reject any offer to purchase the Firm
Shares made through the Underwriter or a selected dealer in whole or in part, and any such rejection shall not be deemed a breach of the Underwriter’s agreements contained herein. This is strictly a “best efforts” offering and there
is no minimum contingency of a specific number of Firm Shares which must be sold prior to proceeding with a closing and the Underwriter is not required to purchase any Shares that are not sold or for which Purchasers have not paid in the Offering.
The Company will not sell or agree to sell any of the Firm Shares otherwise than through the Underwriter until after the Closing Date. In the event any of the Company or any of its executive officers is contacted directly or indirectly by
prospective Purchasers of the Firm Shares, the Company will promptly forward the names of such prospective Purchasers to the Underwriter. 

In addition, the Company hereby grants to the Underwriter, upon the basis of the warranties and representations and subject to the terms and
conditions herein set forth, the option to sell, as agent of the Company, all or a portion of the Additional Shares, for the sole purpose of covering sales in excess of the number of Firm Shares, at the same price per share as sold by the
Underwriter for the Firm Shares. This option may be exercised by Underwriter at any time and from time to time in whole or in part by written notice from the Underwriter to the Company, which notice may be given at any time within 30 days from the
date of this Agreement. Such notice shall set forth (i) the aggregate number of Additional Shares as to which the option is being exercised, (ii) the names and denominations in which the certificates will be delivered and (iii) the date, time
and place at which such certificates will be delivered (such date, the “Additional Closing Date” and such time of such date, the “Additional Time of Purchase”); provided, however, that the Additional
Time of Purchase may be simultaneous with, but shall not be earlier than the Time of Purchase (as defined below) and shall not be earlier than two nor later than five full business days after delivery of such notice of exercise. The Underwriter
may cancel the option at any time prior to its expiration by giving written notice of such cancellation to the Company. 
 If determined
necessary in the judgment of the Underwriter, the Shares being sold to the Purchasers shall be evidenced by the execution of the Subscription Agreements by each of the Purchasers and the Company.

amendment to the Registration Statement or an amendment or supplement to the Prospectus that corrects such statement or omission or effects such compliance. The Company consents to the use of the Prospectus or any amendment or supplement
thereto by the Underwriter.

“Lock-Up Period”), without the prior written consent of the Underwriter. 
 (g) To supply the Underwriter with copies
of all correspondence to and from, and all documents issued to and by, the Commission in connection with the registration of the Shares under the Securities Act or the Registration Statement or the Prospectus, or any amendment or supplement thereto

sale or resale of any of the Shares. 
 5.    Payment of Expenses. The Company agrees to pay, or reimburse if

expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Underwriter Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim,
damage, expense, liability, action, investigation or proceeding arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any “issuer
information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, (B) the

 18 








 
or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or
proceeding, as such fees and expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, expense or liability arises out of or is based upon an untrue
statement or alleged untrue statement in, or omission or alleged omission from, any Registration Statement or the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus made in reliance upon and in conformity
with written information concerning the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for use therein, which information the parties hereto agree is limited to the Underwriter’s Information. This
indemnity agreement is not exclusive and will be in addition to any liability, which the Company may otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Underwriter Indemnified
Party. 
 Without limitation of and in addition to its obligations under the other paragraphs of this Section 7, the Company shall
indemnify and hold harmless the Independent Underwriter, each of its affiliates and each of its directors, officers, members, employees, representatives and agents and their respective affiliates, and each person, if any, who controls the
Independent Underwriter within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act (collectively the “Independent Underwriter Indemnified Parties,” and each an “Independent Underwriter
Indemnified Party”), against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which the Independent Underwriter or any such person may become
subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon the Independent Underwriter’s acting as a “qualified independent
underwriter” (within the meaning of FINRA Rule 5121) in connection with the offering contemplated by this Agreement, and the Company agrees to reimburse each such Independent Underwriter Indemnified Party promptly upon demand for any legal fees
or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating, or preparing to defend, or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection
with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and expenses are incurred. Section 7(c) shall apply equally to any action or proceeding brought against the Independent Underwriter or any such
person in respect of which indemnity may be sought against the Company pursuant to the immediately preceding sentence, except that the Company shall be liable for the expenses of one separate counsel (in addition to any local counsel) for the
Independent Underwriter and any such person, separate and in addition to counsel for the persons who may seek indemnification pursuant to the first paragraph of this Section 7(a), in any such action or proceeding. 

(b) The Underwriter shall indemnify and hold harmless the Company and its directors, its officers who signed the Registration Statement

Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Company Indemnified Party may become subject, under the Securities Act
or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact


  
 19 








 
contained in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement
or the Prospectus, or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the
Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the
extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriters specifically for use
therein, which information the parties hereto agree is limited to the Underwriter’s Information, and shall reimburse the Company Indemnified Parties for any legal or other expenses reasonably incurred by such party in connection with
investigating or preparing to defend or defending against or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred. This
indemnity agreement is not exclusive and will be in addition to any liability which the Underwriter might otherwise have and shall not limit any rights or remedies which may otherwise be available under this Agreement, at law or in equity to the
Company Indemnified Parties.
 (c) Promptly after receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 7, notify such indemnifying party in writing of the commencement of that action;
provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure; and,
provided, further, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such action shall be brought against
an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the
defense of such action with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying
party to the indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel as set forth herein, except as provided herein, the indemnifying party shall not be liable to the indemnified party
under Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense of such action other than reasonable costs of investigation; provided, however, that any indemnified party
shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the fees and expenses of such counsel (other than reasonable costs of investigation which shall remain the expense of the
Company) shall be at the expense of such indemnified party unless (i) in the case of an Underwriter Indemnified Party, the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under
Section 7(a), or (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the
indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action or the indemnifying party does
not diligently defend the action after assumption of the defense, in which 

  
 20 








 
case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not
have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be
responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action; provided, however, that the indemnifying party shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for
all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by the Underwriter if the indemnified parties under this Section 7 consist of any Underwriter Indemnified Party or by the Company if
the indemnified parties under this Section 7 consist of any Company Indemnified Parties. Subject to this Section 7(c), the amount payable by an indemnifying party under Section 7 shall include, but not be limited to,
(x) reasonable legal fees and expenses of counsel to the indemnified party and any other expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection
with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to
the entry of judgment with respect to any pending or threatened action or any claim whatsoever, in respect of which indemnification or contribution could be sought under this Section 7 (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Subject to the provisions of the following sentence, no indemnifying party
shall be liable for settlement of any pending or threatened action or any claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, or if its
consent has been unreasonably withheld or delayed, or if there be a judgment for the plaintiff in any such matter, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of
such settlement or judgment. In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it
shall be liable for any settlement of the nature contemplated herein effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the request for
reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified
party in accordance with such request prior to the date of such settlement. 
 (d) If the indemnification provided for in this
Section 7 is unavailable or insufficient to hold harmless an indemnified party under Section 7(a) or Section 7(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate
to reflect the relative benefits received by the Company on the one hand and the Underwriters 

  
 21 








 
on the other hand from the Offering of the Shares, or (ii) if the allocation provided by clause (i) of this Section 7(d) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 7(d) but also the relative fault of the Company on the one hand and each of the respective Underwriters on the other with respect to the
statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof) as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriter on the other hand with respect to such Offering shall be deemed to be in the same proportion as the total net proceeds from the Offering of the Shares pursuant to this Agreement
(before deducting expenses) received by the Company bear to the total compensation received by the Underwriter in connection with the Offering, in each case as set forth in the table on the cover page of the Prospectus. The relative benefits
received by the Independent Underwriter in its capacity as “qualified independent underwriter” (within the meaning of FINRA Rule 5121) shall be deemed to be equal to the compensation received by the Independent Underwriter for acting in
such capacity. The relative fault of the Company on the one hand and the Underwriter on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct
or prevent such untrue statement, omission, act or failure to act. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(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 payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action,
investigation or proceeding referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with
investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or
proceeding. Notwithstanding the provisions of this Section 7(d), the Underwriter shall not be required to contribute any amount in excess of the total compensation received by the Underwriter hereunder less the amount of any damages
which the Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act and the Independent Underwriter, in
its capacity as “qualified independent underwriter” (within the meaning of FINRA Rule 5121), shall in no event be required to contribute any amount in excess of the total compensation received by the Independent Underwriter for acting in
such capacity hereunder less the amount of any damage which the Independent Underwriter has otherwise paid or become liable to pay by reason of the Independent Underwriter’s acting in such capacity in connection with the offering contemplated
by this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 10(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 

8.    Absence of Fiduciary Relationship. The Company acknowledges and agrees that: 

(a) the Underwriter’s and the Independent Underwriter’s responsibility to the Company is solely contractual in nature, the
Underwriter and the Independent Underwriter have been retained solely to act as an Underwriter and the Independent Underwriter, respectively, in connection with the Offering 

  
 22 








 
and no fiduciary, advisory or agency relationship between the Company and such Underwriter or the Independent Underwriter has been created in respect of any of the transactions contemplated by
this Agreement, irrespective of whether such Underwriter or the Independent Underwriter has advised or is advising the Company on other matters; 

(b) the price of the Shares set forth in this Agreement was established by the Company following discussions and arms-length negotiations
with the Underwriter and the Independent Underwriter, and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement; 

(c) the Underwriter and the Independent Underwriter have not advised, and the Underwriter and the Independent Underwriter are not advising,
the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the transactions contemplated hereby; 

(d) the Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent
investigation and appraisal of the transactions contemplated hereby, and the Underwriter and the Independent Underwriter shall have no responsibility or liability to the Company with respect thereto; 

(e) the Underwriter and the Independent Underwriter have not and will not be rendering an opinion to the Company as to the fairness of the
terms of the offering of the Shares; 
 (f) it has been advised that the Underwriter and the Independent Underwriter, and their respective
affiliates, are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Underwriter and the Independent Underwriter have no obligation to disclose such interests and transactions to the
Company by virtue of any fiduciary, advisory or agency relationship; and 
 (g) it waives, to the fullest extent permitted by law, any
claims it may have against any Underwriter or the Independent Underwriter for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriter and the Independent Underwriter shall not have any liability (whether direct
or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company. 

9.    Successors; Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit
of and be binding upon the Underwriter and the Independent Underwriter, the Company, and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, other than
the persons mentioned in the preceding sentence, any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and all conditions and provisions hereof being intended to be
and being for the sole and exclusive benefit of such persons and for the benefit of no other person; except that the representations, warranties, covenants, agreements and indemnities of the Company contained in this Agreement shall also be for the
benefit of the Underwriter Indemnified Parties and the Independent Underwriter Indemnified Parties, as applicable, and the indemnity of the Underwriters shall be for the 

  
 23 








 
benefit of the Company Indemnified Parties. It is understood that the Underwriter’s and the Independent Underwriter’s responsibility to the Company is solely contractual in nature and
such Underwriter does not owe the Company, or any other party, any fiduciary duty as a result of this Agreement. 

10.    Survival of Indemnities, Representations, Warranties, Etc. The respective indemnities, covenants,
agreements, representations, warranties and other statements of the Company and the Underwriter and the Independent Underwriter, as set forth in this Agreement or made by them respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation made by or on behalf of the Underwriter and the Independent Underwriter, the Company or any person controlling any of them and shall survive delivery of and payment for the Shares. Notwithstanding any
termination of this Agreement, the indemnity and contribution agreements contained in Section 7 and the covenants, representations, warranties set forth in this Agreement shall not terminate and shall remain in full force and effect at all
times.

	 	Re:	B. Riley Financial, Inc. - Public Offering of Shares 

 Dear Sirs: 

In order to induce B. Riley & Co., LLC (the “Underwriter”) to enter into an underwriting agreement with B. Riley
Financial, Inc., a Delaware corporation (the “Company”), with respect to the public offering (the “Offering”) of shares of the Company’s common stock, par value $0.0001 per share (“Common
Stock”), the undersigned hereby agrees that for a period (the “lock-up period”) of 60 days following the date of the final prospectus supplement filed by the Company with the Securities and Exchange Commission in connection
with such Offering (the “Prospectus Supplement”), the undersigned will not, without the prior written consent of B. Riley, directly or indirectly, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of,
any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock (including, without limitation, shares of Common Stock or any such securities which may be deemed to be beneficially owned by the undersigned
in accordance with the rules and regulations promulgated under the Securities Exchange Act of 1934, as the same may be amended or supplemented from time to time (such shares or securities, the “Beneficially Owned Shares”)), (ii)
enter into any swap, hedge or other agreement or arrangement that transfers in whole or in part, the economic risk of ownership of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common
Stock, or (iii) engage in any short selling of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock. The foregoing sentence shall not apply to (a) transactions relating to any
Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock acquired in open market transactions after the completion of the Offering, (b) transfers of any Beneficially Owned Shares, Common
Stock or securities convertible into or exercisable or exchangeable for Common Stock as a bona fide gift, (c) in the case of a natural person, transfers of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or
exchangeable for Common Stock by will or intestate succession or to

any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock to general or limited partners or stockholders or members of the undersigned, (e) in the case of a non-natural person,
transfers of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock (A) in connection with the sale or other bona fide transfer in a single transaction of all or substantially all
of the undersigned’s capital stock, partnership interests, membership interests or other similar equity interests, as the case may be, or all or substantially all of the undersigned’s assets, in any such case not undertaken for the purpose
of avoiding the restrictions imposed by this Agreement or (B) to another corporation, partnership, limited liability company or other business entity so long as the transferee is an affiliate of the undersigned and such transfer is not for value,
(f) in connection with the receipt or vesting of securities issued to the undersigned by the Company pursuant to any equity incentive or other compensatory plans, the withholding by the Company or surrender of such securities and/or any sale or
other disposition of such securities solely in order to satisfy tax liabilities with respect to such issuance or vesting or any deemed disposition or deemed sale with respect to such securities, provided that only one Form 4 shall be filed by or on
behalf of the undersigned during the restricted period in connection with this clause (f), such Form 4 shall not be filed before
[                    ], 2016 and no other filing shall be required or shall be voluntarily made during that period in connection with this
clause (f), or (g) transfers pursuant to a sale or an offer to purchase 100% of the outstanding Common Stock, whether pursuant to a merger, tender offer or otherwise, to a third party or group of third parties; provided that in the case of any
transfer or distribution pursuant to clause (b), (c), (d) or (e), each donee, pledgee, distributee or transferee shall sign and deliver a lock-up agreement substantially in the form of this Agreement; and provided, further, that , without derogating
from the restrictions set forth in clause (f), no filing by any party under the Securities Exchange Act of 1934, as amended, shall be required or shall be voluntarily made during the lock-up period in connection with any transaction or transfer
pursuant to clause (a), (b), (c), (d) or (e). 
 For the purposes of the immediately preceding paragraph, “immediate
family” shall mean spouse, domestic partner, lineal descendant (including adopted children), father, mother, brother or sister of the transferor. 

If (i) the Company issues an earnings release or material news or a material event relating to the Company occurs during the last seventeen
days of the lock-up period, or (ii) prior to the expiration of the lock-up period, the Company announces that it will release earnings results during the sixteen-day period beginning on the last day of the lock-up period, the restrictions imposed by
this Agreement shall continue to apply until the expiration of the eighteen-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. 

In addition, the undersigned hereby waives, from the date hereof until the expiration of the ninety (90) day period following the date of the
Prospectus Supplement, any and all rights, if any, to request or demand registration pursuant to the Securities Act of 1933, as amended, of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock
that are registered in the name of the undersigned or that are Beneficially Owned Shares. In order to enable the aforesaid covenants to be enforced, the undersigned hereby consents to the placing of legends and/or stop transfer orders with the
transfer agent of the Common Stock with respect to any shares of Common Stock, securities convertible into or exercisable or exchangeable for Common Stock or Beneficially Owned Shares. 







 If (i) the Company notifies the Underwriter in writing that it does not intend to proceed with
the Offering, (ii) for any reason the Offering is terminated prior to the payment for and delivery of the Common Stock or (iii) the Offering shall not have been completed by May 31, 2016, then upon the occurrence of any such event, this Agreement
shall immediately be terminated and the undersigned shall be released from its obligations hereunder.
