CONFIDENTIAL

Roth Capital Partners, LLC

888 San Clemente Drive

Newport Beach, CA 92660

Ladies and Gentlemen:

Wireless Ronin Technologies, Inc., a Minnesota corporation (the “Company”), proposes to issue and sell registered securities of the Company, consisting of up to 868,000 units (the “Units”), with each Unit consisting of (i) one share of Common Stock (a “Share,” and collectively the “Shares”) and (ii) one warrant to purchase 0.50 of a share of Common Stock (a “Warrant,” and collectively, the “Warrants”). Such fractional amount will be referred to herein as the “Warrant Ratio.” “Common Stock” means the Company’s common stock, $0.01 par value per share. The shares of Common Stock issuable upon exercise of the Warrants are hereinafter referred to as the “Warrant Shares,” and the Units and the underlying Shares, Warrants and Warrant Shares are hereinafter collectively referred to as the “Securities.”

Subject to the terms of this Placement Agency Agreement (the “Agreement”), Roth Capital Partners, LLC (“Roth” or the “Placement Agent”) shall serve as the exclusive placement agent for the Company, on a “reasonable best efforts” basis, in connection with the proposed offering of the Securities (the “Placement”). The terms of such Placement shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that the Placement Agent would have the power or authority to bind the Company or any Purchaser or creates an obligation for the Company to issue any Securities or complete the Placement. This Agreement and the documents executed and delivered by the Company to the Purchasers in connection with the Placement shall be collectively referred to herein as the “Transaction Documents.” The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase any of the Securities and does not ensure the successful placement of the Securities or any portion thereof, or the success of the Placement Agent with respect to securing any other financing on behalf of the Company. The Placement Agent shall have no authority to bind the Company with respect to any prospective offer to purchase Securities and the Company shall have the sole right to accept offers to purchase Securities and may reject any such offer, in whole or in part.

Section 1. Compensation and Other Fees. As compensation for the services provided by the Placement Agent hereunder, the Company agrees to pay to the Placement Agent:

(a) A cash fee payable immediately upon (but only in the event of) the closing of the Placement equal to seven percent (7.0%) of the aggregate gross proceeds from the sale of the Shares sold at the Closing.

(b) In addition, the Company agrees to pay the Placement Agent, regardless of whether the Placement is consummated, the reasonable out-of-pocket expenses incurred by the Placement Agent in connection with its engagement hereunder, including fees and disbursements of its counsel, travel expenses, and costs relating to filings with FINRA necessary to consummate the Placement; provided, however, that in no event will the amount of fees and expenses paid to the Placement Agent in connection with the Placement, if the Placement is consummated, exceed 8% of the aggregate gross proceeds from the sale of the Shares sold at the Closing.

Section 2. Registration Statement. The Company represents and warrants to, and agrees with, the Placement Agent that:

(a) The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (Registration File No. 333-185885) under the Securities Act of 1933, as amended (the “Securities Act”), which became effective on January 31, 2013, for the registration under the Securities Act of securities of the Company, including the Securities. At the time of such filing, the Company met the requirements of Form S-3 under the Securities Act pursuant to Instruction B.6 to Form S-3. 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 of the Commission promulgated thereunder (the “Rules and Regulations”), 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 that will be set forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, collectively with any registration statement filed pursuant to Rule 462(b) promulgated under the Securities Act (a “Rule 462 Registration Statement”), 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 Base Prospectus and the preliminary prospectus, if any, together with the free writing prospectuses, if any, used in connection with the Placement, including any documents incorporated by reference therein. The term “knowledge” as used in this Agreement with respect to the Company shall mean actual knowledge of the Company’s officers and directors after due and reasonable inquiry.

(b) The Registration Statement (and any further documents to be filed with the Commission in connection with the Placement) contains or will contain, as applicable, 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 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 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. Notwithstanding the foregoing, the Company makes no representation or warranty as to information contained in or omitted from the Registration Statement, the Base Prospectus, the Time of Sale Prospectus, if any, or the Prospectus Supplement, including any amendments or supplements thereto, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Placement Agent expressly for use in the preparation thereof, which information the parties hereto agree is limited to the Placement Agent’s Information (as defined in Section 13). 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, in light of the circumstances under which they were made, not misleading; and any further documents so filed prior to or on the closing of the Placement 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 had a reasonable basis for, and made in good faith, each “forward-looking statement” (within the meaning of Section 27A of the Securities Act or Section 21E of the Exchange Act) contained or incorporated by reference in the Registration Statement, the Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement.

(d) All statistical or market-related data included or incorporated by reference in the Registration Statement, the Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement are based on or derived from sources that the Company reasonably believes to be reliable and accurate, and the Company has obtained the written consent to the use of such data from such sources, except where the failure to have obtained such consent could not have or reasonably be expected to result in a Material Adverse Effect (as defined below).

3

(e) The Company is eligible to use free writing prospectuses in connection with the Placement pursuant to Rules 164 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act in connection with the Placement has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder, 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. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by, on behalf of or used by the Company in connection with the Placement complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. The Company will not, without the prior consent of the Placement Agent, prepare, use or refer to any free writing prospectus.

(f) 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 (as defined below), 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.

(g) The Company represents that the aggregate market value of securities to be sold in the Placement shall not exceed the lesser of (i) the aggregate market value of securities remaining available for issuance under the Registration Statement and (ii) one-third of the aggregate market value of the Company’s public float less the aggregate market value of securities sold pursuant to the Registration Statement or the Company’s Registration Statement on Form S-3 (Registration File No. 333-161700 (the “Prior Registration Statement”)) during the 12 calendar months immediately prior to and including the month of the Placement, in each case calculated in accordance with the requirements of Form S-3 and the rules and regulations relating thereto. The Company further represents that the number of shares of Common Stock, including Common Stock equivalents, sold in the Placement will not exceed 20% of the Company’s outstanding Common Stock, with the relevant calculations made in accordance with Nasdaq Marketplace Rule 5635(d) and the interpretations and guidance relating thereto.

Section 3. Representations Warranties and Certain Agreements. The Company represents and warrants to, and agrees with, the Placement Agent that:

(a) Organization and Qualification. All of the direct and indirect subsidiaries (individually, a “Subsidiary”) of the Company are set forth in the SEC Reports (as defined below). Except as set forth in the SEC Reports, the Company owns, directly or indirectly, all of the capital stock or other equity interests of each Subsidiary free and clear of any “Liens” (which for purposes of this Agreement shall mean a lien, charge, security interest, encumbrance, right of first refusal, preemptive right or other restriction, other than restrictions imposed by applicable securities laws). All the issued and outstanding shares of capital stock of each Subsidiary are validly issued and are fully paid, non-assessable and free of preemptive and similar rights to subscribe for or purchase securities. The Company and each of the Subsidiaries is an entity duly incorporated or otherwise organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization (as applicable), with the requisite power and authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company nor any Subsidiary is in violation or default of any of the

4

provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not have or reasonably be expected to result in (i) a material adverse effect on the legality, validity or enforceability of any Transaction Document, (ii) a material adverse effect on the results of operations, assets, business or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company’s ability to perform in any material respect its obligations under any Transaction Document (any of (i), (ii) or (iii), a “Material Adverse Effect”) and, to the Company’s knowledge, no “Proceeding” (which for purposes of this Agreement shall mean any action, claim, suit, investigation or proceeding (including, without limitation, an investigation or partial proceeding, such as a deposition), whether commenced or threatened) has been instituted in any such jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification.

(b) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into each of the Transaction Documents, to consummate the transactions contemplated hereby and thereby, 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 shareholders in connection therewith other than in connection with the Required Approvals (as defined in Section 3(d) below). 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 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.

(c) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company, the issuance and sale of the Securities (including the Warrant Shares upon exercise of the Warrants) and the consummation by the Company of the other transactions contemplated hereby and thereby do not and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, result in the creation of any Lien upon any of the properties or assets of the Company or any Subsidiary, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not have or reasonably be expected to result in a Material Adverse Effect.

(d) Filings, Consents and Approvals. The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other “Person” (defined as an

5

individual or corporation, partnership, trust, incorporated or unincorporated association, joint venture, limited liability company, joint stock company, government (or an agency or subdivision thereof) or other entity of any kind, including, without limitation, any Trading Market (as defined below)) in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than such filings as are required to be made under applicable federal and state securities laws, rules and regulations promulgated by the Company’s Trading Market and rules and regulations promulgated by FINRA (collectively, the “Required Approvals”), all of which will be made in a timely manner to the extent such filings are required or desirable to be made by the Company, with the exception of filings with FINRA, which the parties have agreed will be made by Roth.

(e) Issuance of the Securities; Registration. The Securities are duly authorized and, when issued and paid for in accordance with the applicable Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens imposed by the Company. The Company has reserved from its duly authorized capital stock the maximum number of shares of Common Stock issuable pursuant to the Transaction Documents. The issuance by the Company of the Securities has been registered under the Securities Act and all of the Securities are (or will be upon issuance) freely transferable and tradable by the Purchasers without restriction (other than any restrictions arising solely from an act or omission of a Purchaser). The Securities are being issued pursuant to the Registration Statement and the issuance of the Securities has been registered by the Company under the Securities Act. The Registration Statement was originally declared effective on January 31, 2013 and is available for the issuance of the Securities thereunder and the Company has not received any notice that the Commission has issued or intends to issue a stop-order with respect to the Registration Statement or that the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or intends or has threatened in writing to do so. The “Plan of Distribution” section under the Registration Statement permits the issuance and sale of the Securities hereunder. Upon receipt of the Securities, the Purchasers will have good and marketable title to the Shares, Warrants, and Warrant Shares (upon issuance thereof), and the Shares and, upon issuance, the Warrant Shares will be freely tradable on the “Trading Market” (which, for purposes of this Agreement shall mean the Nasdaq Capital Market, or any of the following markets or exchanges if the Common Stock is listed or quoted for trading on such markets or exchanges on the date in question: the Nasdaq Global Market, the Nasdaq Global Select Market, the NYSE MKT or the New York Stock Exchange).

(f) Capitalization. The capitalization of the Company is as set forth in the Prospectus Supplement. As of the date of this Agreement, the Company has not issued any capital stock since the date of filing of its most recently filed periodic report under the Exchange Act, other than awards under the Company’s stock option plans, the issuance of shares of Common Stock to employees pursuant to the Company’s employee stock purchase plan and pursuant to the conversion or exercise of securities exercisable, exchangeable or convertible into Common Stock (“Common Stock Equivalents”), which plans are described in the SEC Reports and which awards and exercisable, exchangeable or convertible securities are indicated as being issuable or outstanding in the SEC Reports.

Except as disclosed in the SEC Reports or pursuant to equity compensation plans or agreements filed as exhibits to the SEC Reports, there are no outstanding options, warrants, script rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations convertible into or exercisable or exchangeable for, or giving any Person any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock Equivalents. The issuance and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under such securities. All

6

of the outstanding shares of capital stock of the Company are duly authorized, validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. No further approval or authorization of any shareholder, the Board of Directors of the Company or others is required for the issuance and sale of the Securities. There are no shareholders agreements, voting agreements or other similar agreements with respect to the Company’s capital stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s shareholders.

The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments.

Except for the issuance of the Securities contemplated by this Agreement, no event, liability or development has occurred or exists with respect to the Company or its Subsidiaries or their respective business, properties, operations or financial condition, that would be required to be disclosed by the Company under applicable securities laws at the time this representation is made that has not been publicly disclosed prior to the date that this representation is made.

No executive officer, to the knowledge of the Company, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant, and, to the Company’s knowledge, the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. No material labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of the Company which could reasonably be expected to result in a Material Adverse Effect.

(l) Regulatory Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports, except where the failure to possess such permits could not have or reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any Material Permit, except where such potential revocation or modification would not reasonably be expected to result in a Material Adverse Effect.

(m) Title to Assets. The Company and the Subsidiaries have good and marketable title in fee simple to all real property owned by them that is material to the business of the Company and the Subsidiaries and good and marketable title in all personal property owned by them that is material to the business of the Company and the Subsidiaries, in each case free and clear of all Liens, except as set forth in the SEC Reports and except for Liens created under license or collaboration agreements relating to the Company’s products or Intellectual Property Rights and Liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries and Liens for the payment of federal, state or other taxes, the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases of which the Company and the Subsidiaries are in compliance with the provisions thereof, except where such non-compliance would not have a Material Adverse Effect.

(n) Patents and Trademarks. The Company and the Subsidiaries have, or have rights to use, all patents, patent applications, trademarks, trademark applications, service marks, trade names, trade secrets, inventions, copyrights, licenses and other similar intellectual property rights necessary or material for use in connection with their respective businesses as described in the SEC Reports (collectively, the “Intellectual Property Rights”). To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no existing infringement by another Person of any of the Intellectual Property Rights of the Company which would reasonably be expected to have a Material Adverse Effect. To the knowledge of the Company, none of the Intellectual Property Rights used by the Company or any Subsidiary violates or infringes upon the rights of any Person. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

In connection with our engagement of Roth Capital Partners, LLC (the “Placement Agent”) as placement agent, we hereby agree to indemnify and hold harmless the Placement Agent and its affiliates, controlling persons, directors, officers, shareholders, agents and employees (whether now or formerly employed) of any of the foregoing (individually and 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) (individually and collectively a “Claim”), which 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, including allegations thereof) by the Company, or (ii) any actions taken or omitted to be taken by any Indemnified Person in connection with our engagement of the Placement Agent, or (B) otherwise relate to or arise out of the Placement Agent’s activities on our behalf under the Placement Agent’s engagement, and we shall reimburse any Indemnified Person for all expenses (including the reasonable fees and expenses of counsel) incurred by such Indemnified Person in connection with investigating, preparing or defending any such claim, action, suit or proceeding. We will not, however, be responsible for any Claim, which is finally judicially determined (i.e., it is no longer subject to appeal) to have resulted solely from the gross negligence or willful misconduct of any person seeking indemnification hereunder. Except as specifically set forth below, we further agree that no Indemnified Person shall have any liability to us for or in connection with our engagement of the Placement Agent except for any Claim incurred by us solely as a result of any Indemnified Person’s gross negligence or willful misconduct. The Placement Agent agrees to indemnify and hold harmless Wireless Ronin Technologies, Inc. (the “Company,” “we,” “our” or “us”), each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signed the Registration Statement against any Claim to the same extent as the foregoing indemnity from the Company to the Placement Agent, but only insofar as such Claim arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Prospectus Supplement, or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case 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 Prospectus Supplement in reliance upon and in conformity with written information furnished to the Company by the Placement Agent expressly for use therein. The Company hereby acknowledges that the Placement Agent’s Information (as such term is defined in the placement agency letter agreement dated as of the date hereof) comprises the only information that the Placement Agent has furnished to the Company expressly for use in the Prospectus Supplement. This indemnity agreement will be in addition to any liability that the Placement Agent might otherwise have.

We further agree that we will not, without the prior written consent of the Placement Agent, which consent shall not be unreasonably withheld, delayed or conditioned, 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 hereunder from any and all liability arising out of such Claim.

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 us in writing of such complaint or of such assertion or institution but failure to so notify us shall not relieve us from any obligation we may have hereunder, unless and only to the extent that such failure results in the forfeiture by us of substantial rights and defenses. If we so elect or are requested by such Indemnified Person, we 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 and provides written correspondence to us, 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 us, 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 us, then such Indemnified Person may employ its own separate counsel to represent or defend it in any such Claim and we shall pay the reasonable fees and expenses of one such counsel. Notwithstanding anything herein to the contrary, if we fail 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 us 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 any Claim in which we assume the defense, the Indemnified Person shall have the right to participate in such Claim and to retain its own counsel therefor at its own expense.

We agree that if any indemnity sought by an Indemnified Person hereunder is unavailable for any reason then (whether or not a Placement Agent is the Indemnified Person), we and the Placement Agent shall contribute to the Claim for which such indemnity is held unavailable in such proportion as is appropriate to reflect the relative benefits to us, on the one hand, and the Placement Agent on the other, in connection with the Placement Agent’s engagement referred to above, subject to the limitation that in no event shall the amount of the Placement Agent’s contribution to such Claim exceed the amount of fees (and not including any reimbursable expenses) actually received by such Placement Agent from us pursuant to the Placement Agent’s engagement. We hereby agree that the relative benefits to us, on the one hand, and the Placement Agent on the other, with respect to the Placement Agent’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 us pursuant to the transaction (whether or not consummated) for which the Placement Agent is engaged to render services bears to (b) the fee paid or proposed to be paid (and not including any reimbursable expenses) to such Placement Agent in connection with such engagement.

Our indemnity, reimbursement and contribution obligations under this agreement 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.

The validity and interpretation of this agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York applicable to agreements made and to be fully performed therein (excluding the conflicts of laws rules).
