STRICTLY CONFIDENTIAL

Michael Tardugno

President & Chief Executive Officer

Celsion Corporation

997 Lenox Drive, Suite 100

Lawrenceville, NJ 08648

Dear Mr. Tardugno:

This letter (this “Agreement”) constitutes the agreement between Celsion Corporation, a Delaware corporation (the “Company”) and H.C. Wainwright & Co., LLC (“HCW” or the “Placement Agent”) that HCW shall serve as the exclusive investment bank, in connection with the proposed registered and/or unregistered placement or series of placements to occur during the term of this Agreement (such placements, collectively the “Offering”). The Offering shall consist of registered or unregistered securities (the “Securities”) of the Company that are newly issued by the Company in consideration of cash paid to the Company by the investors in such Offering. For the avoidance of doubt, no mergers, other acquisitions or other strategic transactions by or of the Company or its affiliates shall be deemed an “Offering.” The terms of such Offering and the Securities shall be mutually agreed upon by the Company, HCW and, if a direct Offering, the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein implies that HCW would have the power or authority to bind the Company or any Purchaser, and the Company shall not, and nothing herein implies that the Company shall, have an obligation to issue any Securities or complete an Offering. This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with an Offering shall be collectively referred to herein as the “Transaction Documents.” The date of a closing of an Offering shall be referred to herein as the “Closing Date.” The Company expressly acknowledges and agrees that the execution of this Agreement does not constitute a commitment by HCW or any Purchaser to purchase the Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of HCW with respect to securing any other financing on behalf of the Company. In the event the Offering will consist of registered securities, the provisions of Annex A will apply in addition to the provisions set forth herein.

In the event that an Offering is a registered direct Offering, the sale of Securities to any Purchaser will be evidenced by a purchase agreement (“Purchase Agreement”) between the Company and such Purchaser in a form reasonably satisfactory to the Company and HCW. Prior to the signing of any Purchase Agreement, officers of the Company with responsibility for financial affairs will be available, upon reasonable advance notice, to answer inquiries from prospective Purchasers.

A.     Fees and Expenses. In connection with the Services described above, the Company shall pay to HCW the following compensation:

1.     Offering Agent’s Fee. The Company shall pay to HCW a cash placement fee (the “Offering Agent’s Closing Fee”) equal to 7.5% of the aggregate purchase price paid by each purchaser of Securities that are placed in the Offering. The Offering Agent’s Closing Fee shall be paid at each closing of the Offering (the “Closing”) from the gross proceeds of the Securities sold.

2.     [RESERVED]

3.     Expenses. Subject to compliance with FINRA Rule 5110(f)(2)((D), in addition to any fees payable to HCW hereunder, but only if an Offering is consummated, the Company hereby agrees to reimburse HCW for all itemized invoices for reasonable travel and other out-of-pocket expenses incurred in connection with HCW’s engagement, which expenses shall not include the fees and expenses of HCW’s counsel. Such reimbursement shall be limited to 1% of the gross proceeds received by the Company in the applicable Offering (but in no event more than $50,000 for each applicable Offering) and shall be paid at the Closing from the gross proceeds of the Securities sold (provided, however, that such expense cap in no way limits or impairs the indemnification and contribution provisions of this Agreement). Such reimbursement shall be payable immediately upon (but only in the event of) the closing of an Offering.

Notwithstanding anything herein to the contrary, at the request of HCW, the Company shall agree to amend this Agreement in writing to reduce compensation payable hereunder to the extent and as necessary in order comply with FINRA rules or regulations.

B.     Term and Termination of Engagement. The term (the “Term”) of HCW’s exclusive engagement will begin on the date hereof and end on October 31, 2013. Notwithstanding anything to the contrary contained herein, the provisions concerning indemnification, contribution and the Company’s obligations to pay fees and reimburse expenses contained herein will survive any expiration or termination of this Agreement. For clarity, HCW’s exclusive engagement shall be to act as exclusive placement agent or underwriter for one or more best efforts Offerings and underwritten Offerings during the Term. In the event that an Offering is an underwritten Offering, prior to the commencement of the underwritten Offering, the Company shall negotiate the terms of an underwriting agreement with HCW, the starting point of which shall be HCW’s standard form, modified as appropriate to reflect the terms of an underwritten Offering and containing such terms, covenants, conditions, representations, warranties, and providing for the delivery of legal opinions, comfort letters and officer’s certificates, all in form and substance satisfactory to HCW and its counsel and the Company. Notwithstanding anything herein to the contrary, HCW’s exclusive engagement hereunder shall not apply with respect to capital raising transaction(s) during the Term which are for the sole purpose of financing merger and/or acquisition transactions by the Company or any of its subsidiaries.

C.     [RESERVED]

D.     Use of Information. The Company will furnish HCW such written information as HCW reasonably requests in connection with the performance of its services hereunder. The Company understands, acknowledges and agrees that, in performing its services hereunder, HCW will use and rely entirely upon such information as well as publicly available information regarding the Company and other potential parties to an Offering and that HCW does not assume responsibility for independent verification of the accuracy or completeness of any information, whether publicly available or otherwise furnished to it, concerning the Company or otherwise relevant to an Offering, including, without limitation, any financial information, forecasts or projections considered by HCW in connection with the provision of its services.

E.     Publicity. In the event of the consummation or public announcement of any Offering, HCW shall have the right to disclose its participation in such Offering, including, without limitation, the placement at its cost of “tombstone” advertisements in financial and other newspapers and journals, provided no confidential or nonpublic information is disclosed therein.

F.     Securities Matters. The Company shall be responsible for any and all compliance with the securities laws applicable to it, including Regulation D and the Securities Act of 1933, as amended (the “Securities Act”), and Rule 506 promulgated thereunder, and unless otherwise agreed in writing, all state securities (“blue sky”) laws. HCW agrees to cooperate with counsel to the Company in that regard.

G.     Indemnity.

1.      The Company hereby agrees to indemnify and hold harmless HCW and its affiliates, and the respective controlling persons, directors, officers, members, shareholders, agents and employees of any of the foregoing (collectively the “Indemnified Persons”), from and against any and all claims, actions, suits, proceedings (including those of shareholders), damages, liabilities and expenses incurred by any of them (including the reasonable fees and expenses of counsel), as incurred, (collectively a “Claim”), that are (A) related to or arise out of (i) any actions taken or omitted to be taken (including any untrue statements made or any statements omitted to be made) by the Company, or (ii) any actions taken or omitted to be taken by any Indemnified Person in connection with the Company’s engagement of HCW, or (B) otherwise relate to or arise out of HCW’s activities on the Company’s behalf under HCW’s engagement, and the Company shall reimburse any Indemnified Person for all expenses (including the reasonable fees and expenses of counsel) as incurred by such Indemnified Person in connection with investigating, preparing or defending any such claim, action, suit or proceeding, whether or not in connection with pending or threatened litigation in which any Indemnified Person is a party. The Company will not, however, be responsible for any Claim that is finally judicially determined to have resulted from the gross negligence or willful misconduct or bad faith of any person seeking indemnification for such Claim. The Company further agrees that no Indemnified Person shall have any liability to the Company for or in connection with the Company’s engagement of HCW except for any Claim incurred by the Company as a result of such Indemnified Person’s gross negligence or willful misconduct.

2.     The Company further agrees that it will not, without the prior written consent of HCW, settle, compromise or consent to the entry of any judgment in any pending or threatened Claim in respect of which indemnification may be sought hereunder (whether or not any Indemnified Person is an actual or potential party to such Claim), unless such settlement, compromise or consent includes an unconditional, irrevocable release of each Indemnified Person from any and all liability arising out of such Claim.

3.     Promptly upon receipt by an Indemnified Person of notice of any complaint or the assertion or institution of any Claim with respect to which indemnification is being sought hereunder, such Indemnified Person shall notify the Company in writing of such complaint or of such assertion or institution but failure to so notify the Company shall not relieve the Company from any obligation it may have hereunder, except and only to the extent such failure results in the forfeiture by the Company of substantial rights and defenses. If the Company so elects or is requested by such Indemnified Person, the Company will assume the defense of such Claim, including the employment of counsel reasonably satisfactory to such Indemnified Person and the payment of the fees and expenses of such counsel. In the event, however, that legal counsel to such Indemnified Person reasonably determines that having common counsel would present such counsel with a conflict of interest or if the defendant in, or target of, any such Claim, includes an Indemnified Person and the Company, and legal counsel to such Indemnified Person reasonably concludes that there may be legal defenses available to it or other Indemnified Persons different from or in addition to those available to the Company, then such Indemnified Person may employ its own separate counsel to represent or defend him, her or it in any such Claim and the Company shall pay the reasonable fees and expenses of such counsel. Notwithstanding anything herein to the contrary, if the Company fails timely or diligently to defend, contest, or otherwise protect against any Claim, the relevant Indemnified Party shall have the right, but not the obligation, to defend, contest, compromise, settle, assert crossclaims, or counterclaims or otherwise protect against the same, and shall be fully indemnified by the Company therefor, including without limitation, for the reasonable fees and expenses of its counsel and all amounts paid as a result of such Claim or the compromise or settlement thereof. In addition, with respect to any Claim in which the Company assumes the defense, the Indemnified Person shall have the right to participate in such Claim and to retain his, her or its own counsel therefor at his, her or its own expense.

4.     The Company agrees that if any indemnity sought by an Indemnified Person hereunder is held by a court to be unavailable for any reason then (whether or not HCW is the Indemnified Person), the Company and HCW shall contribute to the Claim for which such indemnity is held unavailable in such proportion as is appropriate to reflect the relative benefits to the Company, on the one hand, and HCW on the other, in connection with HCW’s engagement referred to above, subject to the limitation that in no event shall the amount of HCW’s contribution to such Claim exceed the amount of fees actually received by HCW from the Company pursuant to HCW’s engagement. The Company hereby agrees that the relative benefits to the Company, on the one hand, and HCW on the other, with respect to HCW’s engagement shall be deemed to be in the same proportion as (a) the total value paid or proposed to be paid or received by the Company or its stockholders as the case may be, pursuant to the Offering (whether or not consummated) for which HCW is engaged to render services bears to (b) the fee paid or proposed to be paid to HCW in connection with such engagement.

5.     The Company’s indemnity, reimbursement and contribution obligations under this Agreement (a) shall be in addition to, and shall in no way limit or otherwise adversely affect any rights that any Indemnified Party may have at law or at equity and (b) shall be effective whether or not the Company is at fault in any way.

H.     Limitation of Engagement to the Company. The Company acknowledges that HCW has been retained only by the Company, that HCW is providing services hereunder as an independent contractor (and not in any fiduciary or agency capacity) and that the Company’s engagement of HCW is not deemed to be on behalf of, and is not intended to confer rights upon, any shareholder, owner or partner of the Company or any other person not a party hereto as against HCW or any of its affiliates, or any of its or their respective officers, directors, controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), employees or agents. Unless otherwise expressly agreed in writing by HCW, no one other than the Company is authorized to rely upon this Agreement or any other statements or conduct of HCW, and no one other than the Company is intended to be a beneficiary of this Agreement. The Company acknowledges that any recommendation or advice, written or oral, given by HCW to the Company in connection with HCW’s engagement is intended solely for the benefit and use of the Company’s management and directors in considering a possible Offering, and any such recommendation or advice is not on behalf of, and shall not confer any rights or remedies upon, any other person or be used or relied upon for any other purpose. HCW shall not have the authority to make any commitment binding on the Company. The Company, in its sole discretion, shall have the right to reject any investor introduced to it by HCW. The Company agrees that it will perform and comply with the covenants and other obligations set forth in the Transaction Documents, and that HCW will be entitled to rely on the representations, warranties, agreements and covenants of the Company contained in such Transaction Documents as if such representations, warranties, agreements and covenants were made directly to HCW by the Company.

I.     Limitation of HCW’s Liability to the Company. HCW and the Company further agree that neither HCW nor any of its affiliates or any of its or their respective officers, directors, controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), employees or agents shall have any liability to the Company, its security holders or creditors, or any person asserting claims on behalf of or in the right of the Company (whether direct or indirect, in contract, tort, for an act of negligence or otherwise) for any losses, fees, damages, liabilities, costs, expenses or equitable relief arising out of or relating to this Agreement or the Services rendered hereunder, except for losses, fees, damages, liabilities, costs or expenses that arise out of or are based on any action of or failure to act by HCW and that are finally judicially determined to have resulted solely from the gross negligence or willful misconduct or bad faith of HCW. HCW represents and warrants that as of the date of this Agreement and to its knowledge, HCW has any and all licenses and permits of whatever kind which may be required by law in order that HCW may lawfully perform all of its duties and obligations set forth herein and required to be performed by HCW.

J.     Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be fully performed therein. Any disputes that arise under this Agreement, even after the termination of this Agreement, will be heard only in the state or federal courts located in the City of New York, State of New York. The parties hereto expressly agree to submit themselves to the jurisdiction of the foregoing courts in the City of New York, State of New York. The parties hereto expressly waive any rights they may have to contest the jurisdiction, venue or authority of any court sitting in the City and State of New York. In the event of the bringing of any action, or suit by a party hereto against the other party hereto, arising out of or relating to this Agreement, the party in whose favor the final judgment or award shall be entered shall be entitled to have and recover from the other party the costs and expenses incurred in connection therewith, including its reasonable attorneys’ fees. Any rights to trial by jury with respect to any such action, proceeding or suit are hereby waived by HCW and the Company.

Annex A

Additional Provisions With Respect to a Registered Placement

The Company represents and warrants to, and agrees with, the Placement Agent that:

(A)     The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (Registration File No. 333-183286) under the Securities Act of 1933, as amended (the “Securities Act”), which became effective on September 14, 2012, for the registration under the Securities Act of the Securities. At the time of such filing, the Company met the requirements of Form S-3 under the Securities Act. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies with said Rule. The Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a supplement to the form of prospectus included in such registration statement relating to the placement of the Securities and the plan of distribution thereof and has advised the Placement Agent of all further information (financial and other) with respect to the Company required to be set forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the “Registration Statement”; such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus”; and the supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus Supplement.” Any reference in this Agreement to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”) pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the Company's knowledge, is threatened by the Commission. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and the “Time of Sale Prospectus” means the preliminary prospectus, if any, together with the free writing prospectuses, if any, used in connection with the Offering, including any documents incorporated by reference therein.

(B)     The Registration Statement (and any further documents to be filed with the Commission) contains all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Base Prospectus, the Time of Sale Prospectus, if any, and the Prospectus Supplement, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations. Each of the Base Prospectus, the Time of Sale Prospectus, if any, and the Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein (with respect to Incorporated Documents incorporated by reference in the Base Prospectus or Prospectus Supplement), in light of the circumstances under which they were made not misleading; and any further documents so filed and incorporated by reference in the Base Prospectus, the Time of Sale Prospectus, if any, or Prospectus Supplement, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, as applicable, and will not contain any 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. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other documents required to be described in the Base Prospectus, the Time of Sale Prospectus, if any, or Prospectus Supplement, or to be filed as exhibits or schedules to the Registration Statement, which have not been described or filed as required.

(C)     The Company has delivered, or will as promptly as practicable deliver, to the Placement Agent complete conformed copies of the Registration Statement and of each consent and certificate of experts, as applicable, filed as a part thereof, and conformed copies of the Registration Statement (without exhibits), the Base Prospectus, the Time of Sale Prospectus, if any, and the Prospectus Supplement, as amended or supplemented, in such quantities and at such places as the Placement Agent reasonably requests. Neither the Company nor any of its directors and officers has distributed and none of them will distribute, prior to the Closing Date, any offering material in connection with the offering and sale of the Securities other than the Base Prospectus, the Time of Sale Prospectus, if any, the Prospectus Supplement, the Registration Statement, copies of the documents incorporated by reference therein and any other materials permitted by the Securities Act.

(D)     The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary action on the part of the Company and no further action is required by the Company, its board of directors or its stockholders in connection therewith other than in connection with the Shareholder Approval (as such term is defined in the Purchase Agreement to be entered into on or about the date hereof). Each Transaction Document has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof and thereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms except (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(E)     FINRA Affiliations. There are no affiliations with any FINRA member firm among the Company’s officers, directors or, to the knowledge of the Company, any five percent (5%) or greater stockholder of the Company, except as set forth in the Base Prospectus or in the Prospectus Supplement.

SECTION 4.     CLOSING. The obligations of the Placement Agent and the Purchasers, and the closing of the sale of the Securities hereunder are subject to the accuracy, in all material respects, when made and on the Closing Date, of the representations and warranties on the part of the Company and its Subsidiaries contained herein, to the accuracy, in all material respects, of the statements of the Company and its Subsidiaries made in any certificates pursuant to the provisions hereof, to the performance by the Company and its Subsidiaries of their obligations hereunder, and to each of the following additional terms and conditions:

(A)     No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been initiated or threatened by the Commission, and any request for additional information on the part of the Commission (to be included in the Registration Statement, the Base Prospectus or the Prospectus Supplement or otherwise) shall have been complied with to the reasonable satisfaction of the Placement Agent.

(B)     The Placement Agent shall not have discovered and disclosed to the Company on or prior to the Closing Date that the Registration Statement, the Base Prospectus or the Prospectus Supplement or any amendment or supplement thereto contains an untrue statement of a fact which, in the opinion of counsel for the Placement Agent, is material or omits to state any fact which, in the opinion of such counsel, is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(C)     All corporate proceedings (other than the Shareholder Approval) and other legal matters incident to the authorization, form, execution, delivery and validity of each of this Agreement, the Securities, the Registration Statement, the Base Prospectus and the Prospectus Supplement and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all material respects to counsel for the Placement Agent, and the Company shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

(D)     The Placement Agent shall have received from outside counsel to the Company such counsel’s written opinion, addressed to the Placement Agent and the Purchasers dated as of the Closing Date, in form and substance reasonably satisfactory to the Placement Agent.

(G)     Subsequent to the execution and delivery of this Agreement, there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange, the Nasdaq National Market or the NYSE Alternext US or in the over-the-counter market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall have been suspended or minimum or maximum prices or maximum ranges for prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by federal or state authorities or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, (iii) the United States shall have become engaged in hostilities in which it is not currently engaged, the subject of an act of terrorism, there shall have been an escalation in hostilities involving the United States, or there shall have been a declaration of a national emergency or war by the United States, or (iv) there shall have occurred any other calamity or crisis or any change in general economic, political or financial conditions in the United States or elsewhere, if the effect of any such event in clause (iii) or (iv) makes it, in the sole judgment of the Placement Agent, impracticable or inadvisable to proceed with the sale or delivery of the Securities on the terms and in the manner contemplated by the Base Prospectus, the Time of Sale Prospectus, if any, and the Prospectus Supplement.

(H)     No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental agency or body which would, as of the Closing Date, prevent the issuance or sale of the Securities or materially and adversely affect or potentially and adversely affect the business or operations of the Company; 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 or materially and adversely affect or potentially and adversely affect the business or operations of the Company.
