PLACEMENT AGENCY AGREEMENT 

October 23, 2013 
 Roth Capital Partners, LLC 

888 San Clemente Drive 
 Newport Beach, CA 92660 

Ladies and Gentlemen: 
 Delcath Systems, Inc., a
Delaware corporation (the “Company”), proposes, subject to the terms and conditions herein, to issue and sell an aggregate of up to (i) 20,960,000 shares (the “Shares”) of its common stock, par value $0.01 per
share (the “Common Stock”), and (ii) 9,432,000 warrants to purchase shares of Common Stock (the “Warrants”) to certain investors (each an “Investor” and, collectively, the
“Investors”), in an offering under its registration statement on Form S-3 (Registration No. 333-183675). The shares of Common Stock issuable upon exercise of the Warrants are hereinafter referred to as the “Warrant
Shares” and the Shares, the Warrants and the Warrant Shares are hereinafter referred to as the “Securities”. The Securities are more fully described in the Prospectus (as defined below). The Company desires to engage Roth Capital
Partners, LLC (“Roth”) in connection with such issuance and sale of the Securities. 
 The Company hereby confirms its
agreement with you as follows: 
 1. Agreement to Act as Placement Agent. 

(a) On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the
terms and conditions of this Agreement between the Company and you, Roth shall be the Company’s exclusive placement agent (in such capacity, the “Placement Agent”), on a best efforts basis, in connection with the issuance and
sale by the Company of the Securities to the Investors in a proposed takedown under the Registration Statement (as defined below), with the terms of each offering to be subject to market conditions and negotiations between the Company, the Placement
Agent and the prospective Investors (such takedown shall be referred to herein as the “Offering”). As compensation for services rendered, and provided that any of the Securities are sold to Investors in the Offering, on the
Closing Date (as defined below) of the Offering, the Company shall pay to the Placement Agent an amount equal to 7.0% of the gross proceeds received by the Company from the sale of the Securities to all Investors (the “Placement
Fee”) plus reimbursable costs and expenses of the Placement Agent pursuant to Section 4. The Placement Fee shall be payable to the Placement Agent at Closing, based upon the sale of the Shares, as provided in the Subscription
Agreements (defined below). The sale of the Securities shall be made pursuant to securities purchase agreements in the form included as Exhibit A hereto (the “Subscription Agreements”) on the terms described on
Exhibit B hereto. The Company shall have the sole right to accept offers to purchase the Securities and may reject any such offer in whole or in part. Notwithstanding the foregoing, it is understood and agreed that the Placement
Agent or any of their respective affiliates may, solely at their discretion and without any obligation to do so, purchase Securities as principal; provided, however, that any such purchases by the Placement Agent (or their respective
affiliates) shall be fully disclosed to the Company and approved by the Company in accordance with the previous sentence. 






 (b) This Agreement shall not give rise to any commitment by the Placement Agent
to purchase any of the Securities, and the Placement Agent shall have no authority to bind the Company. The Placement Agent shall act on a best efforts basis and does not guarantee that it will be able to raise new capital in the
Offering. The Placement Agent may retain other brokers or dealers to act as sub-agents on its behalf in connection with the Offering, the fees of which shall be paid out of the Placement Fee.

(c) The Company acknowledges and agrees that the Placement Agent shall act as an independent contractor, and not as a
fiduciary, and any duties of the Placement Agent with respect to investment banking services to the Company, including the offering of the Securities contemplated hereby (including in connection with determining the terms of the Offering), shall be
contractual in nature, as expressly set forth herein, and shall be owed solely to the Company. Each party disclaims any intention to impose any fiduciary or similar duty on the other. Additionally, the Placement Agent has not advised, nor is it
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. 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 Placement Agent shall have no responsibility or liability to the Company with respect thereto. Any
review by the Placement Agent of the Company, the transactions contemplated hereby or other matters relating to such transactions has been and will be performed solely for the benefit of the Placement Agent and has not been and shall not be on
behalf of the Company or any other person. It is understood that the Placement Agent has not and will not be rendering an opinion to the Company as to the fairness of the terms of the Offering. Notwithstanding anything in this Agreement to the
contrary, the Company acknowledges that the Placement Agent may have financial interests in the success of the Offering contemplated hereby that are not limited to the Placement Fee. The Company hereby waives and releases, to the fullest extent
permitted by law, any claims that the Company may have against the Placement Agent with respect to any breach or alleged breach of fiduciary duty. 

(d) Payment of the purchase price for, and delivery of, the Securities shall be made at a closing (the
“Closing”) at the offices of LeClairRyan, A Professional Corporation, counsel for the Placement Agent, located at 885 Third Avenue, New York, New York, at 10 a.m., New York time, as soon as practicable after the determination of the
public offering price of the Securities, but not later than on October 28, 2013 except as otherwise agreed upon by the Company and the Placement Agent (such date of payment and delivery being herein called the “Closing
Date”). All such actions taken at the Closing shall be deemed to have occurred simultaneously. No Securities which the Company has agreed to sell pursuant to this Agreement and the Subscription Agreements shall be deemed to have
been purchased and paid for, or sold by the Company, until such Securities shall have been delivered to the Investor thereof against payment therefor by such Investor. If the Company shall default in its obligations to deliver Securities to an
Investor whose offer it has accepted, the Company shall indemnify and hold the Placement Agent harmless against any loss, claim or damage incurred by the Placement Agent arising from or as a result of such default by the Company. 

(e) On the Closing Date, (i) the Investors will wire the purchase price for their respective Securities through their
delivery versus payment (“DVP”) account set up at Roth as executing broker. Roth will use its Syndicate account as a facilitation account to settle Investors purchases. The Company shall deliver or cause to be delivered the Securities to
Roth on behalf of the Investors, with the delivery of the Shares to be made, through the facilities of The Depository Trust Company’s DWAC system, and the delivery of the Warrants to be made by mail to the Investors to the addresses set forth
on the applicable Subscription Agreement. Upon confirmation of the Shares by Roth on behalf of the Investors, Roth will instruct its clearing firm to release the wire to the Company. This will all occur during a closing call scheduled to settle the
transaction. 
 (f) The Securities shall be registered in such names and in such denominations as the Placement Agent shall
request by written notice to the Company.

held thereby under leases that are in full force and effect.

Disclosure Package and the Prospectus. Neither the Company nor any Subsidiary has any tax deficiency that has been or, to the knowledge of the Company, is reasonably likely to be asserted or threatened against it that would result in a Material

Neither the Company nor any Subsidiary has reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not have a Material Adverse Effect. 
 (hh) Accounting Controls. The Company and each
Subsidiary maintains a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are

Issuer Free Writing Prospectus, if any, (to the extent not previously delivered) to the Placement Agent prior to 11:00 a.m. Eastern time, on the second business day next succeeding the date of this Agreement in such quantities as the Placement Agent

(c) Amendments or Supplements. The Company will not, during the Prospectus Delivery Period in connection with
the Offering contemplated by this Agreement, file any amendment or supplement to the Registration Statement or the Prospectus unless a copy thereof shall first have been submitted to the Placement Agent within a reasonable period of time prior to

 17 







 (d) Free Writing Prospectuses. The Company will (i) not make any
offer relating to the Securities that would constitute an “issuer free writing prospectus” (as defined in Rule 433) or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act)
required to be filed by the Company with the Commission under Rule 433 under the Securities Act unless the Placement Agent approve its use in writing prior to first use (each, a “Permitted Free Writing Prospectus”); provided,
that the prior written consent of the Placement Agent hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectus(es) included in Schedule I hereto, (ii) treat each Permitted Free Writing Prospectus as an Issuer
Free Writing Prospectus, (iii) comply with the requirements of Rules 164 and 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and
record keeping and (iv) not take any action that would result in the Placement Agent or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf
of such Placement Agent that such Placement Agent otherwise would not have been required to file thereunder. The Company will satisfy the conditions in Rule 433 under the Securities Act to avoid a requirement to file with the Commission any

notify the Placement Agent promptly, and will, if requested, confirm such notification in writing: (i) the receipt of any comments of, or requests for additional information from, the Commission; (ii) the time and date of any filing of any
post-effective amendment to the Registration Statement or any amendment or supplement to the Disclosure Package or the Prospectus, (iii) the time and date when any post-effective amendment to the Registration Statement becomes effective;
(iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or any post-effective amendment thereto or any order preventing or suspending the use of the Disclosure Package, the Prospectus
or any Issuer Free Writing Prospectus, or the initiation of any proceedings for that purpose or the threat thereof; (v) of receipt by the Company of any notification with respect to any suspension or the approval of the Shares and Warrant
Shares from any securities exchange upon which it is listed for trading or included or designated for quotation, or the initiation or threatening of any proceeding for such purpose. The Company will use its reasonable best efforts to prevent
the issuance or invocation of any such stop order or suspension by the Commission and, if any such stop order or suspension is so issued or invoked, to obtain as soon as possible the withdrawal or removal thereof. 

(f) Filing of Amendments or Supplements. If, during the Prospectus Delivery Period, any event shall occur or condition
exist as a result of which it is necessary to amend or supplement the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Disclosure Package) in order to make the statements therein, in the light of the
circumstances when the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Disclosure Package) is delivered to an Investor, not misleading, or if, in the opinion of counsel for the Placement Agent, it is necessary
to amend or supplement the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Disclosure Package) to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to
the Placement Agent, either amendments or supplements to the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Disclosure Package) so that the statements in the Prospectus (or, if the Prospectus is not yet
available to prospective purchasers, the Disclosure Package) as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Disclosure Package)
is delivered to an Investor, be misleading or so that the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Disclosure Package), as amended or 

  
 18 







 
supplemented, will comply with law. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free
Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement relating to the Securities or included or would include an untrue statement of a material fact or omitted or would omit to state a material
fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company promptly will notify the Placement Agent and will promptly amend or supplement, at its own
expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(h) Lock-Up Period. The Company hereby agrees that, without the prior written consent of Roth, it will not, during the
period ending on and including the 30th day after the date hereof (as the same may be extended as described below, the “Lock-Up Period”), (i) offer, pledge, issue, sell, contract to sell, lend, or otherwise transfer or dispose
of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock, including, but not limited to, any pursuant to the Company’s Sales Agreement with Cowen and
Company, LLC dated March 13, 2013 and the Company’s Stock Purchase Agreement with Terrapin Opportunity, L.P. dated December 5, 2012; or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part,
any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of shares of Common Stock or such other securities, in cash or otherwise; or

thereto) or the Prospectus, and (3) the issuance of employee stock options not exercisable during the Lock-Up Period and the grant of restricted stock awards or restricted stock units pursuant to equity incentive plans described in the

of the Lock-Up Period, or (y) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this
clause shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless Roth waives such extension in writing; provided, however,
that this sentence shall not apply if (A) the Company meets the applicable requirements of Rule 139(a)(1) under the Securities Act in the manner contemplated by NASD Conduct Rule 2711(f)(4) (B) the Company’s securities are
“actively traded” as defined in Rule 101(c)(1) of Regulation M of the Exchange Act and (C) the provisions of NASD Conduct Rule 2711(f)(4) do not restrict the publication or distribution, by the Placement Agent, of any research reports
relating to the Company during the 15 days before or after the last day of the Lock-up Period (before giving effect to such extension).

prior written consent of the Placement Agent, unless in the reasonable judgment of the Company and its counsel, and after notification to the Placement Agent, such press release or communication is required by law or the rules of NASDAQ, in which
case the Company shall use its reasonable best efforts to allow the Placement Agent reasonable time to comment on such release or other communication in advance of such issuance.

the jurisdiction of incorporation of the Company, a registrar for the Shares and Warrant Shares.

Placement Agent. 
 (d) Action Preventing Issuance. No action shall have been taken and no statute, rule,

which would, as of the Closing Date, prevent the issuance or sale of the Securities; and no injunction, restraining order or order of any other nature by any federal or state court of competent
jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Securities. 
 (e)
Objection of Placement Agent. No Prospectus or amendment or supplement to the Registration Statement shall have been filed to which the Placement Agent shall have objected in writing, which objection shall not be unreasonable. The

change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company from that set forth in the Disclosure Package and the Prospectus that, in the Placement

(iii) a general moratorium on commercial banking activities declared by either federal or any state authorities; 

(iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a
national emergency or war, which in the Placement Agent’s sole judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities in the manner contemplated in the Prospectus; or 

(v) any calamity or crisis, change in national, international or world affairs, act of God, change in the international or
domestic markets, or change in the existing financial, political or economic conditions in the United States or elsewhere, that in the Placement Agent’s judgment makes it impracticable or inadvisable to proceed with the public offering or the
delivery of the Securities in the manner contemplated in each of the Disclosure Package and the Prospectus.

Statement, the Disclosure Package and the Prospectus, and other matters required by the Placement Agent.

Company or any of the Subsidiaries taken as a whole, (E) any dividend or distribution of any kind declared, paid or made on the capital stock of the Company or any of the Subsidiaries or (F) any loss or damage (whether or not insured) to

 23 







 (iii) no stop order suspending the effectiveness of the Registration Statement
or any part thereof or any amendment thereof or the qualification of the Securities for offering or sale, nor suspending or preventing the use of the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus shall have been issued,

any amendments thereof or supplements thereto (and any documents filed under the Exchange Act and deemed to be incorporated by reference into the Disclosure Package and the Prospectus), and (A) (i) the Registration Statement and any
amendment thereof did not contain when the Registration Statement (or such amendment) became effective, any untrue statement of a material fact or omit to state when the Registration Statement (or such amendment) became effective, any material fact
required to be stated therein or necessary to make the statements therein not misleading and (ii) as of the Time of Sale, neither the Disclosure Package nor any individual Issuer Limited Use Free Writing Prospectus, when considered together
with the Disclosure Package, contained any untrue statement of material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and (iii) the

make the statements therein, in light of the circumstances under which they were made, not misleading, and (B) since the Time of Sale, there has occurred no event required to be set forth in an amendment or supplement to the Registration
Statement, the Disclosure Package or the Prospectus which has not been so set forth and there has been no document required to be filed under the Exchange Act that upon such filing would be deemed to be incorporated by reference in to the Disclosure

6. Indemnification and Contribution. 

(a) Indemnification of the Placement Agent. The Company agrees to indemnify, defend and hold harmless each of the
Placement Agent, its respective directors and officers, and each person, if any, who controls such Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and
assigns of all of the foregoing persons, from and against any loss, damage, claim or liability, which, jointly or severally, such Placement Agent or any such person may become subject under the Securities Act, the Exchange Act, or other federal or
state statutory law or regulation, the common law or otherwise, (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, damage, claim or liability (or actions in
respect thereof as contemplated below) arises out of or is based upon: (i) 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
to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus or
the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which
they were made, not misleading; and, in the case of (i) and (ii) above, to reimburse such Placement Agent and each such controlling person for any and all reasonable expenses (including reasonable fees and disbursements of counsel) as such
expenses are incurred by such Placement Agent or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the
foregoing indemnity shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, it arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in or omitted
from, and in conformity with information concerning such Placement Agent furnished in writing by or on behalf of such Placement Agent to the Company expressly for use therein, which information the parties hereto agree is limited to the Placement
Agent Information or (iii) any untrue statement or alleged untrue statement of any material fact contained in the Company’s investor presentation slides in the form furnished by the Company under Form 8-K on October 17, 2013.
Notwithstanding the foregoing, the Company will not be liable to the Placement Agent pursuant to this Section 6(a) to the extent that any such loss, damage, claim or liability is found in a final, non-appealable judgment by a court of
competent jurisdiction to have resulted from the Placement Agent’s willful misconduct or gross negligence. 

  
 25 







 (b) Indemnification of the Company. The Placement Agent will indemnify,
defend and hold harmless the Company, its directors and officers, and any person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and
assigns of all of the foregoing persons, from and against any loss, claim, damage, liability or expense, as incurred to which, jointly or severally, the Company or any such person may become subject under the Securities Act, the Exchange Act, or
other federal or state statutory law or regulation, the common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Placement Agent), insofar as such loss, claim, damage,
liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) 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 to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact
contained in any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made
therein, in light of the circumstances under which they were made, not misleading, in the case of each of (i) and (ii) above, to the extent but only to the extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in the Registration Statement, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information concerning such Placement Agent furnished in
writing by or on behalf of such Placement Agent to the Company expressly for use therein and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any
such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, that the parties hereto hereby agree that such
written information provided by the Placement Agent consists solely of the Placement Agent Information. Notwithstanding the provisions of this Section 6(b), in no event shall any indemnity by the Placement Agent under this
Section 6(b) exceed the Placement Fee. 
 (c) Notice and Procedures. If any action, suit or
proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Company or the Placement Agent (as applicable, the “indemnifying
party”) pursuant to subsection (a) or (b), respectively, of this Section 6, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party
shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party
shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise, except to the extent such failure results in the forfeiture by the indemnifying party of substantial rights or
defenses. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the
employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding, (ii) the indemnifying party shall not have, within a reasonable period of time in light of the
circumstances, employed counsel to defend such Proceeding or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with
those available to such indemnifying party, in any of which events such reasonable fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for
the expenses of more than one separate counsel (in addition to any local counsel) 

  
 26 







 
in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). An indemnifying party shall not be liable
for any settlement of any Proceeding (including by consent to the entry of any judgment) effected without its written consent but, if settled with its written consent or if there be a final judgment for the plaintiff, such indemnifying party agrees
to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of counsel (which fees and expenses shall be reasonably documented) as contemplated by the second sentence of this Section 6(c), then the indemnifying party
agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior
notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened Proceeding in respect of
which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that
are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 6 is unavailable to an
indemnified party under subsections (a) or (b) of this Section 6 or insufficient to hold an indemnified party harmless in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each applicable
indemnifying party shall, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in subsection
(a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other from the offering of the Securities or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the
one hand and the Placement Agent on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Placement Agent on the other hand shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities (before deducting expenses) received by
the Company and the Placement Fee received by the Placement Agent, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Securities. The relative fault of the Company on the one hand and
the Placement Agent 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 by the Placement Agent, on the other hand, and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company
and the Placement Agent agree that it would not be just and equitable if contribution pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable
considerations referred to in the first sentence of this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this
Section 6(d) shall be deemed to include any legal or 

  
 27 







 
other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this
Section 6(d). Notwithstanding the provisions of this Section 6(d), the Placement Agent shall not be required to contribute any amount in excess of the Placement Fee. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 

(e) Representations and Agreements to Survive Delivery. The obligations of the Company under this
Section 6 shall be in addition to any liability which the Company may otherwise have. The indemnity and contribution agreements of the parties contained in this Section 6 and the covenants, warranties and representations
of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Placement Agent, any person who controls
the Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or any affiliate of the Placement Agent, or by or on behalf of the Company, its directors or officers or any person who
controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and (iii) the issuance and delivery of the Securities. The Company and the Placement Agent agree promptly to notify
each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors in connection with the issuance and sale of the Securities, or in connection with the Registration
Statement, the Disclosure Package or the Prospectus. 
 7. Information Furnished by Placement Agent. The Company acknowledges that
the statements set forth in the tenth paragraph under the heading “Plan of Distribution” in the Prospectus (the “Placement Agent Information”) constitute the only information relating to the Placement Agent furnished in
writing to the Company by the Placement Agent as such information is referred to in Sections 2 and 6 hereof. 
 8.
Termination. 
 (a) The Placement Agent shall have the right to terminate this Agreement by giving notice as hereinafter
specified at any time at or prior to the Closing Date, without liability on the part of the Placement Agent to the Company, if (i) prior to delivery and payment for the Securities (A) trading in securities generally shall have been
suspended or materially limited on or by the New York Stock Exchange, the NASDAQ Stock Market, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market, or the NYSE MKT (each, a “Trading Market”),
(B) trading in the Common Stock of the Company shall have been suspended or materially limited on any exchange or in the over-the-counter market, (C) a general moratorium on commercial banking activities shall have been declared by federal
or New York state authorities, (D) there shall have occurred any outbreak or material escalation of hostilities or acts of terrorism involving the United States or there shall have been a declaration by the United States of a national emergency
or war, (E) there shall have occurred any other calamity or crisis or any material change in general economic, political or financial conditions in the United States or elsewhere, if the effect of any such event specified in clause (D) or
(E), in the reasonable judgment of the Placement Agent, makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Securities on the Closing Date on the terms and in the manner contemplated by this
Agreement, the Disclosure Package and the Prospectus, or (ii) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Disclosure Package, there has been, (A) any Material
Adverse Effect or (B) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character that, in 

  
 28 







 
the reasonable judgment of the Placement Agent would, individually or in the aggregate, result in a Material Adverse Effect and which would, in the reasonable judgment of the Placement Agent,
make it impracticable or inadvisable to proceed with the offering or the delivery of the Securities on the terms and in the manner contemplated in the Disclosure Package. Any such termination shall be without liability of any party to any other
party except that the provisions of Section 4, Section 6, Section 8(b) and Section 11 hereof shall at all times be effective notwithstanding such termination. 

(b) If this Agreement shall be terminated by the Placement Agent pursuant to Section 5,
Section 8(a)(i)(B) or Section 8(a)(ii)(A) or (2) the sale of the Securities to Investors is not consummated because of any failure, refusal or inability on the part of the Company to comply with the terms or perform any
agreement or obligation of this Agreement or any Subscription Agreement, other than by reason of a default by the Placement Agent, the Company will, in addition to paying the amounts described in Section 4 hereof, reimburse the Placement
Agent for all of their reasonable and actual out-of-pocket disbursements (including, but not limited to, the reasonable fees and disbursements of its counsel).
