The terms and conditions of the Warrants are set forth in the form of Exhibit B attached hereto. The shares of Common Stock issuable upon exercise of the Warrants are referred to herein as the “Warrant Shares” and, together with the Units, the Shares and the Warrants, are referred to herein as the “Securities”). The Company hereby confirms its agreement with Canaccord Genuity Inc. (“Canaccord” or, the “Placement Agent”) as set forth below. The Units are more fully described in the Prospectus (as defined below).

1. Agreement to Act as Placement Agent; Delivery and Payment. On the basis of the representations, warranties and agreements of the Company herein contained, and subject to the terms and conditions set forth in this Agreement:

(a) The Company hereby engages Canaccord, as the exclusive agent of the Company, to, on a commercially reasonable efforts basis, solicit offers to purchase Units from the Company on the terms and subject to the conditions set forth in the Subscription Agreements and Prospectus (as defined below). Canaccord shall use commercially reasonable efforts to assist the Company in obtaining performance by each Investor whose offer to purchase the Units was solicited by Canaccord and accepted by the Company, but Canaccord shall not, except as otherwise provided in this Agreement, have any liability to the Company in the event any such purchase is not consummated for any reason. Under no circumstances will Canaccord or any of its affiliates be obligated to underwrite or purchase any of the Units for its own account or otherwise provide any financing. Canaccord shall act solely as the Company’s agent and not as principal. Canaccord shall not have any authority to bind the Company with respect to any prospective offer to purchase Units and the Company shall have the sole right to accept offers to purchase Units and may reject any such offer, in whole or in part. Canaccord has the right, in its discretion, without notice to the Company, to reject any offer to purchase Units received by it, in whole or in part, and any such rejection shall not be deemed a breach of this Agreement.

(b) As compensation for services rendered by Canaccord hereunder, on the Closing Date (as defined below), the Company shall pay or cause to be paid to Canaccord by wire transfer of immediately available funds to an account or accounts designated by Canaccord, an aggregate amount equal to six percent (6%) of the gross proceeds received by the Company from the sale of the Units on such Closing Date. Such amount may be deducted from the payment made by the Investor(s) to the Company and paid directly to Canaccord on the Closing Date (the “Agency Fee”). Canaccord agrees that the foregoing compensation, together with any expense reimbursement payable hereunder, constitutes all of the compensation that Canaccord shall be entitled to receive in connection with the offering contemplated hereby. Canaccord may allow concessions, or pay commissions, to other dealers participating in the offering of the Units.

(c) The Units are being sold to the Investors at a price of $2.50 per Unit (the “Purchase Price”) as set forth on the cover page of the Prospectus (as defined below). The purchases of Units by the Investors shall be evidenced by the execution of the Subscription Agreements by each of the parties thereto in the form attached hereto as Exhibit A.

(d) Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing Date, the Company shall not, without the prior written consent of Canaccord, solicit or accept offers to purchase Units otherwise than through Canaccord in accordance herewith.

(e) No Units 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 Units shall have been delivered to the Investor purchasing such Units against payment therefor by such Investor. If the Company shall default in its obligations to deliver Units to an Investor whose offer it has accepted, the Company shall indemnify and hold Canaccord harmless against any loss, claim, damage or liability directly or indirectly arising from or as a result of the default by the Company in accordance with the procedures set forth in Section 6(c) hereof.

Neither the Company nor any of its subsidiaries has received notice of any claim against the Company or any of its subsidiaries, nor does the Company or any of its subsidiaries have knowledge of any such claim, alleging the infringement by the Company or any of its subsidiaries of any patent, trademark, service xxxx, trade name, copyright, trade secret, license in or other intellectual property right or franchise right of any person. All right, title and interest to the patents, patent applications, trademarks, and service-marks in the name of the Company, and applications and registrations thereof (together the “Company Registered IP”) belong exclusively to the Company or its subsidiaries. The Company is not aware of any third party infringing any of the Company Registered IP or other proprietary Company Intellectual Property. All fees and documents necessary to maintain the Company Registered IP have been paid and filed. The Company and each of its subsidiaries has taken all reasonable steps to protect, maintain and safeguard its rights in all Intellectual Property, including the execution of appropriate nondisclosure and confidentiality agreements. The consummation of the transactions contemplated by this Agreement will not result in the loss or impairment of or payment of any additional amounts with respect to, nor require the consent of any other person in respect of, the Company’s or any of its subsidiaries’ right to own, use, hold or otherwise commercially exploit any of the Intellectual Property as owned, used, held or otherwise commercially exploited in the conduct of the businesses as currently conducted. The Company and each of its subsidiaries has duly and properly filed or caused to be filed with the United States Patent and Trademark Office (the “PTO”) and applicable foreign and international patent authorities all patent applications owned by the Company and its subsidiaries, including any patent application which has previously issued or granted into patent. To the knowledge of the Company, the Company and each of its subsidiaries has complied with the PTO’s duty of candor and disclosure for the patent applications owned by the Company or its subsidiaries, including any patent application owned by the Company which has previously issued or granted into a patent (together the “Company Patents”), and has made no material misrepresentation in the Company Patents. The Company is not aware of any information material to a determination of patentability regarding the Company Patents not previously called to the attention of the PTO or similar foreign authority which requires such submission. The Company is not aware of any information not previously called to the attention of the PTO or similar foreign authority that would preclude the grant of a patent for the Company Patents. The Company has no knowledge of any information that would preclude the Company or any of its subsidiaries from having clear title to the Company Patents. To the knowledge of the Company, all of the issued or granted Company Patents are valid and enforceable. All inventors of the Company Patents have duly executed assignments assigning all their right, title and interest in the Company Patents to the Company or its subsidiaries. To the Company’s knowledge, no employee of the Company or any of its subsidiaries is the subject of any claim or proceeding involving a violation of any term of any employment contract, patent disclosure agreement, invention assignment agreement, non-competition agreement, non-solicitation agreement, nondisclosure agreement or any restrictive covenant to or with a former employer where the basis of such violation relates to such employee’s employment with the Company or any of the Company’s subsidiaries or actions undertaken by the employee while employed with the Company or any of the Company’s subsidiaries.

(cc) No Labor Disputes. No labor problem or dispute with the employees of the Company or any of the Company’s subsidiaries exists, or, to the Company’s knowledge, is threatened or imminent, which would reasonably be expected to result in a Material Adverse Effect. The Company is not aware that any key employee or significant group of employees of the Company or any of the Company’s subsidiaries plans to terminate employment with the Company or any of the Company’s subsidiaries. Neither the Company nor any of its subsidiaries has engaged in any unfair labor practice. Except for matters which would not, individually or in the aggregate, result in a Material Adverse Effect, (i) there is (A) no unfair labor practice complaint pending or, to the Company’s knowledge, threatened against the Company or any of its subsidiaries before the National Labor Relations Board, and no grievance or arbitration proceeding arising out of or under collective bargaining agreements is pending or to the Company’s knowledge, threatened, (B) no strike, labor dispute, slowdown or stoppage pending or, to the Company’s knowledge, threatened against the Company or any of its subsidiaries and (C) no union representation dispute currently existing concerning the employees of the Company or any of its subsidiaries and (ii) to the Company’s knowledge, (A) no union organizing activities are currently taking place concerning the employees of the Company or any of its subsidiaries and (B) there has been no violation of any federal, state, local or foreign law relating to discrimination in the hiring, promotion or pay of employees, any applicable wage or hour laws or any provision of the Employee Retirement Income Security Act of 1974 (“ERISA”) or the rules and regulations promulgated thereunder concerning the employees of the Company or any of its subsidiaries.

(dd) Taxes. The Company and each of its subsidiaries (i) has timely filed all necessary federal, state, local and foreign income and franchise tax returns (or timely filed applicable extensions therefor) that have been required to be filed and (ii) is not in default in the payment of any taxes which were payable pursuant to such returns or any assessments with respect thereto, other than any which the Company or any of its subsidiaries is contesting in good faith and for which adequate reserves have been provided and reflected in the Company’s financial statements included in the Registration Statement, the Disclosure Package and the Prospectus. Neither the Company nor any of its subsidiaries 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 Adverse Effect. Neither the Company nor any of its subsidiaries has engaged in any transaction which is a corporate tax shelter or which could be characterized as such by the Internal Revenue Service or any other taxing authority.

(ee) ERISA. The Company and each of its subsidiaries is in compliance in all material respects with all presently applicable provisions of ERISA; no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company or any of its subsidiaries would have any liability; neither the Company nor any of its subsidiaries has incurred and does not expect to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Company or any of its subsidiaries would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

(ff) Compliance with Environmental Laws. The Company and its subsidiaries are in compliance, in all material respects, with all foreign, federal, state and local rules, laws and regulations relating to the use, treatment, storage and disposal of hazardous or toxic substances or waste and protection of health and safety or the environment which are applicable to their businesses (“Environmental Laws”). Except such as are described in the Registration Statement, the Disclosure Package and the Prospectus or matters which would not, individually or in the aggregate, result in a Material Adverse Effect, there has been no storage, generation, transportation, handling, treatment, disposal, discharge, emission, or other release of any kind of toxic or other wastes or other hazardous substances by, due to, or caused by the Company or any of its subsidiaries (or, to the Company’s knowledge, any other entity for whose acts or omissions the Company or any of its subsidiaries is or may otherwise be liable) upon any of the property now or previously owned or leased by the Company or any of its subsidiaries, or upon any other property, in violation of any law, statute, ordinance, rule, regulation, order, judgment, decree or permit or which would, under any law, statute, ordinance, rule (including rule of common law), regulation, order, judgment, decree or permit, give rise to any liability; and except such as are described in the Registration Statement, the Disclosure Package and the Prospectus or matters which would not, individually or in the aggregate, result in a Material Adverse Effect, there has been no reportable disposal, discharge, emission or other release of any kind onto such property or into the environment surrounding such property of any toxic or other wastes or other hazardous substances with respect to which the Company or any of its subsidiaries has knowledge. In the ordinary course of business, the Company and its subsidiaries conduct periodic reviews of the effect of Environmental Laws on their business and assets, in the course of which they identify and evaluate associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or permits issued thereunder, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such reviews, the Company has reasonably concluded that such associated costs and liabilities would not have, singularly or in the aggregate, a Material Adverse Effect.

(gg) Insurance. The Company and each of its subsidiaries maintains or is covered by insurance provided by recognized, financially sound and reputable institutions with insurance policies in such amounts and covering such risks as the Company believes is (i) adequate for the conduct of its business and the value of its properties and (ii) customary for companies engaged in similar businesses in similar industries. All such insurance is fully in force. The Company has no reason to believe that it and its subsidiaries will not be able to renew their 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. Neither the Company nor any of its subsidiaries has been denied any material insurance policy or coverage for which it has applied. Neither the Company nor any of its subsidiaries insures risk of loss through any captive insurance, risk retention group, reciprocal group or by means of any fund or pool of assets specifically set aside for contingent liabilities other than as described in the Disclosure Package.

Except such as are described in the Registration Statement, the Disclosure Package and the Prospectus, the Company 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 recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except such as are described in the Registration Statement, the Disclosure Package and the Prospectus, there are no significant deficiencies or material weaknesses in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize, or report financial data to management and the Board of Directors of the Company. The Company is not aware of any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such controls, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(ii) Disclosure Controls. The Company has established, maintains and evaluates “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act), which (i) are designed to ensure that material information relating to the Company and its subsidiaries is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared, (ii) have been evaluated for effectiveness as of the end of the last fiscal period covered by the Registration Statement; and (iii) such disclosure controls and procedures are effective to perform the functions for which they were established. The Audit Committee of the Board of Directors of the Company (the “Audit Committee”) is not reviewing or investigating, and neither the Company’s independent auditors nor its internal auditors have recommended that the Audit Committee review or investigate, (i) adding to, deleting, changing the application of or changing the Company’s disclosure with respect to, any of the Company’s material accounting policies, (ii) any manner which could result in a restatement of the Company’s financial statements for any annual or interim period during the current or prior three fiscal years, or (iii) a significant deficiency, material weakness, change in internal control over financial reporting or fraud involving management or other employees who have a significant role in the internal control over financial reporting.

The minute books of the Company and each of its subsidiaries have been made available upon request to Canaccord and its counsel, and such books (i) contain a complete summary of all meetings and actions of the board of directors (including each board committee) and shareholders of the Company (or analogous governing bodies and interest holders, as applicable), and each of its subsidiaries since the time of its incorporation or organization through the date of the latest meeting and action, and (ii) accurately in all material respects reflect all transactions referred to in such minutes.

(kk) Contracts; Off-Balance Sheet Interests. There is no document, contract, permit or instrument, or off-balance sheet transaction (including without limitation, any “variable interests” in “variable interest entities,” as such terms are defined in Financial Accounting Standards Board Interpretation No. 46) of a character required by the Securities Act or the Rules and Regulations to be described in the Registration Statement or the Disclosure Package or to be filed as an exhibit to the Registration Statement or document incorporated by reference therein, which is not described or filed as required. Each description of a document, contract, permit or instrument in the Registration Statement or the Disclosure Package accurately reflects in all material respects the terms of the underlying document, contract, permit or instrument. The documents, contracts, permits and instruments described in the immediately preceding sentence to which the Company is a party have been duly authorized, executed and delivered by the Company, constitute valid and binding agreements of the Company, are enforceable against and by the Company in accordance with the terms thereof and are in full force and effect on the date hereof. Neither the Company nor any of its subsidiaries, if a subsidiary is a party, nor to the Company’s knowledge, any other party is in default in the observance or performance of any term or obligation to be performed by it under any such agreement, and no event has occurred which with notice or lapse of time or both would constitute such a default, in any case which default or event, individually or in the aggregate, would have a Material Adverse Effect. No default exists, and no event has occurred which with notice or lapse of time or both would constitute a default, in the due performance and observance of any term, covenant or condition, by the Company or a subsidiary, if a subsidiary is a party thereto, of any agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or its properties or business or a subsidiary or the subsidiary’s properties or business may be bound or affected which default or event, individually or in the aggregate, would have a Material Adverse Effect.

(ll) No Undisclosed Relationships. No relationship, direct or indirect, exists between or among the Company on the one hand and the directors, officers, stockholders, customers or suppliers of the Company or any of their affiliates on the other hand, which is required to be described in the Registration Statement, the Disclosure Package or the Prospectus or a document incorporated by reference therein and which has not been so described.

(mm) Brokers Fees.

(nn) Forward-Looking Statements. No forward-looking statements (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in either the Disclosure Package or the Prospectus have been made or reaffirmed without a reasonable basis therefor or have been disclosed other than in good faith.

If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company will (i) promptly notify Canaccord so that any use of the Disclosure Package may cease until it is amended or supplemented and (ii) amend or supplement the Disclosure Package to correct such statements or omission. If, during the Prospectus Delivery Period, any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Prospectus to comply with the Securities Act, the Company will (A) promptly notify Canaccord of such event and (B) promptly prepare and file with the Commission and furnish, at its own expense, to Canaccord and, to the extent applicable, the dealers and any other dealers upon request of Canaccord, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

The Company will satisfy the conditions in Rule 433 under the Securities Act to avoid a requirement to file with the Commission any electronic road show.

(d) Conflicting Issuer Free Writing Prospectus.

(e) Representations and Warranties.

6. Indemnification and Contribution.

(a) Indemnification of the Placement Agent. The Company agrees to indemnify, defend and hold harmless Canaccord, its affiliates and each of its and their respective directors, officers, members, employees, representatives and agents and any person who controls Canaccord within the meaning of 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 losses, claims, damages, expenses or liabilities, joint or several, to which 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 losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or in any materials or information provided to Investors by, or with the approval of, the Company in connection with the marketing of the offering of the Common Stock (“Marketing Materials”), including any roadshow or investor presentations made to Investors by the Company (whether in person or electronically) or arise out of or are 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, or (ii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein, or (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law, and will reimburse Canaccord for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability, expense or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, expense, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any such amendment or supplement, any Issuer Free Writing Prospectus or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by Canaccord, specifically for use in the preparation thereof, which information the parties hereto agree is limited to the Placement Agent’s Information.

(b) Indemnification of the Company. Canaccord agrees to indemnify, defend and hold harmless the Company against any losses, claims, damages, expenses or liabilities to which the Company 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 Canaccord), insofar as such losses, claims, damages, expenses or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus or Marketing Materials, or arise out of or are 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 Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, Marketing Materials or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by Canaccord, specifically for use in the preparation thereof, which information the parties hereto agree is limited to the Placement Agent’s Information, and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action. Notwithstanding the provisions of this Section 6(b), in no event shall any indemnity by Canaccord under this Section 6(b) exceed the total compensation received by Canaccord in accordance with Section 1(b) hereof.

(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 Canaccord (as applicable, the “Indemnifying Party”) pursuant to subsections (a) or (b) above, 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 have the right to assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the Indemnifying 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 the Indemnifying Party has been materially prejudiced by such failure; and provided, further, that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under subsection (a) or (b) above. 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 the Indemnified Party in such Proceeding or (iii) such Indemnified Party or parties shall have reasonably concluded upon written advice of counsel that there may be one or more legal defenses available to it or them which are different from, additional to or in conflict with those available to such Indemnifying Party (in which case such Indemnifying Party shall not have the right to direct that portion of the defense of such Proceeding on behalf of the Indemnified Party or parties, but such Indemnifying Party or parties may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the 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) 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 effected without its written consent but, if settled with its written consent, 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. 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 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 60 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, 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 subsections (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Party or parties on the one hand and the Indemnified Party or parties on the other hand from the offering of the Units 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 Indemnifying Party or parties on the one hand and the Indemnified Party or parties 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 Canaccord on the other hand shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Units (before deducting expenses) received by the Company bear to the discounts and commissions received by Canaccord. The relative fault of the Company on the one hand and Canaccord 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 Canaccord, on the other hand, and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written information furnished to the Company by Canaccord for use in the Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Placement Agent’s Information.

(e) Allocation. The Company and Canaccord agree that it would not be just and equitable if contribution pursuant to subsection (d) above 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 subsection (d) above. Notwithstanding the provisions of this Section 6(e), Canaccord shall not be required to contribute any amount in excess of the total commissions received by Canaccord in accordance with Section 1(b) less the amount of any damages which Canaccord has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act. 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. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity.

(f) 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 contained in this Section 6 and the covenants, agreements, 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 Canaccord, any person who controls Canaccord within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or any affiliate of Canaccord, 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 Units. The Company and Canaccord 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 Units, or in connection with the Registration Statement, the Disclosure Package or the Prospectus.

7. Information Furnished by Placement Agents. The parties hereto acknowledge and agree that, for all purposes of this Agreement, the “Placement Agent’s Information” consists solely of the statements concerning the Placement Agent in the first paragraph under the heading “Plan of Distribution.”

8. Termination. Canaccord 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 Canaccord to the Company, if (i) prior to delivery and payment for the Units (A) trading in securities generally shall have been suspended on or by the New York Stock Exchange, the NYSE Amex, the NASDAQ Global Market, the NASDAQ Capital Market or in the over the counter market (each, a “Trading Market”), (B) trading in the Common Stock of the Company shall have been suspended on any Trading Market or by the Commission, (C) a general moratorium on commercial banking activities shall have been declared by federal or New York state authorities or a material disruption shall have occurred in commercial banking or securities settlement or clearance services in the United States, (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 Canaccord, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Units on the Closing Date on the terms and in the manner contemplated by this Agreement, the Disclosure Package and the Prospectus, (ii) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Disclosure Package or incorporated by reference therein, there has been any Material Adverse Effect, (iii) the Company shall have failed, refused or been unable to comply with the terms or perform any agreement or obligation of this Agreement or any Subscription Agreements, other than by reason of a default by Canaccord, or (iv) any condition of Canaccord’s obligations hereunder is not fulfilled. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4, Section 6, and Section 12 hereof shall at all times be effective notwithstanding such termination.

9. Notices. All statements, requests, notices and agreements hereunder shall be in writing or by facsimile, and:

11. Governing Law; Submission to Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to the conflicts of laws provisions thereof. Except as set forth below, no Proceeding may be commenced, prosecuted or continued in any court other than the courts of State of New York located in the City and County of New York or the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Company hereby consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any court in which any Proceeding arising out of or in any way relating to this Agreement is brought by any third party against Canaccord. The Company hereby waives all right to trial by jury in any Proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final judgment in any such Proceeding brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts in the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

12. No Fiduciary Relationship. The Company hereby acknowledges and agrees that:

(a) No Other Relationship. Canaccord has been retained solely to act as the exclusive placement agent in connection with the offering of the Company’s securities. The Company further acknowledges that Canaccord is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that Canaccord act or be responsible as a fiduciary to the Company, its management, stockholders, creditors or any other person in connection with any activity that Canaccord may undertake or has undertaken in furtherance of the offering of the Company’s securities, either before or after the date hereof, irrespective of whether Canaccord has advised or is advising the Company on other matters. Canaccord hereby expressly disclaims any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect.

(b) Arm’s-Length Negotiations. The price of the Units set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Investors and Canaccord, and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement.

(c) Absence of Obligation to Disclose. The Company has been advised that Canaccord and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that Canaccord has no obligation to disclose such interests or transactions to the Company by virtue of any fiduciary, advisory or agency relationship.

(d) Waiver. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against Canaccord with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions and agrees that Canaccord shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim to any person asserting a fiduciary duty claim on behalf of the Company, including stockholders, employees or creditors of the Company.

13. Headings. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

14. Amendments and Waivers. No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the party to be bound thereby. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.

15. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original and all such counterparts shall together constitute one and the same instrument. Delivery of an executed counterpart by fax or portable document format (.pdf) shall be effective as delivery of a manually executed counterpart thereof.

16. Research Analyst Independence. The Company acknowledges that Canaccord’s research analysts and research department are required to be independent from its investment banking division and are subject to certain regulations and internal policies, and that Canaccord’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their investment banking division. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against Canaccord with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by Canaccord’s investment banking division. The Company acknowledges that Canaccord is a full service securities firm and as such from time to time, subject to applicable securities laws, rules and regulations, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Company; provided, however, that nothing in this Section 16 shall relieve Canaccord of any responsibility or liability it may otherwise bear in connection with activities in violation of applicable securities laws, rules or regulations.

17. Entire Agreement. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof.

18. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph, clause or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph, clause or provision hereof. If any section, paragraph, clause or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

19. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

The shares of Common Stock issuable upon exercise of the Warrants are referred to herein as the “Warrant Shares” and, together with the Units, the Shares and the Warrants, are referred to herein as the “Offered Securities”).

THIS CERTIFIES THAT, for value received, [______________], or permitted registered assigns (the “Holder”), is entitled to subscribe for and purchase at the Exercise Price (defined below) from American DG Energy Inc., a Delaware corporation (the “Company”), up to [____________] shares of the common stock of the Company, par value $0.001 per share (the “Common Stock”).

(E) “Trading Day” shall mean (a) any day on which the Common Stock is listed or quoted and traded on its primary Trading Market, (b) if the Common Stock is not then listed or quoted and traded on any Eligible Market, then a day on which trading occurs on the OTC Bulletin Board (or any successor thereto), or (c) if trading does not occur on the OTC Bulletin Board (or any successor thereto), any Business Day.

B-1

(F) “Trading Market” shall mean the NYSE Amex or any other Eligible Market, or any national securities exchange, market or trading or quotation facility on which the Common Stock is then listed or quoted.

2. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth on the signature page hereto (or at such other address as it may designate by notice in writing to the Holder):

(A) An executed Notice of Exercise in the form attached hereto;

(B) Payment of the Exercise Price either (i) in cash or by check, or (ii) pursuant to Section 2.1 below; and

Execution and delivery of the Notice of Exercise shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Exercise Shares, if any.

Certificates for Exercise Shares purchased hereunder shall be transmitted by the Company’s transfer agent (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust & Clearing Corporation through its Deposit Withdrawal Agent Commission system if the Company is a participant in such system, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise within three (3) business days from the delivery to the Company of the Notice of Exercise, surrender of this Warrant and payment of the aggregate Exercise Price as set forth above. This Warrant shall be deemed to have been exercised on the date the latest of the Warrant, Notice of Exercise and Exercise Price are received by the Company.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

Subject to Section 2.4, to the extent permitted by law, the Company’s obligations to issue and deliver Exercise Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or entity or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other person or entity of any obligation to the Company or any violation or alleged violation of law by the Holder or any other person or entity, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Exercise Shares. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Exercise Shares upon exercise of this Warrant as required pursuant to the terms hereof.

X =	Y (A-B)
	A

Where X = the number of Exercise Shares to be issued to the Holder

Y =

the number of shares of Common Stock purchasable under this Warrant or, if only a portion of this Warrant is being exercised, the portion of this Warrant being canceled (at the date of such calculation)

A =

the fair market value of one share of the Company’s Common Stock (at the date of such calculation)

B =

Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the “fair market value” of one share of Common Stock shall mean (i) the average of the closing sales prices for the shares of Common Stock on the NYSE Amex or other Eligible Market where the Common Stock is listed or traded as reported by Bloomberg Financial Markets (or a comparable reporting service of national reputation selected by the Company and reasonably acceptable to the Holder if Bloomberg Financial Markets is not then reporting sales prices of such security) (collectively, “Bloomberg”) for the five (5) consecutive trading days immediately prior to the Exercise Date, or (ii) if the NYSE Amex is not the principal Trading Market for the shares of Common Stock, the average of the reported sales prices reported by Bloomberg on the principal Trading Market for the Common Stock during the same period, or, if there is no sales price for such period, the last sales price reported by Bloomberg for such period, or (iii) if neither of the foregoing applies, the last sales price of such security in the over-the-counter market on the pink sheets or bulletin board for such security as reported by Bloomberg, or if no sales price is so reported for such security, the last bid price of such security as reported by Bloomberg or (iv) if fair market value cannot be calculated as of such date on any of the foregoing bases, the fair market value shall be as determined by the Board of Directors of the Company in the exercise of its good faith judgment.

B-3

2.2 ISSUANCE OF NEW WARRANTS. Upon any partial exercise of this Warrant, the Company, at its expense, will forthwith and, in any event within five business days, issue and deliver to the Holder a new warrant or warrants of like tenor, registered in the name of the Holder, exercisable during the balance of the Exercise Period, in the aggregate, for the balance of the number of shares of Common Stock remaining available for purchase under this Warrant.

2.3 PAYMENT OF TAXES AND EXPENSES. The Company shall pay any recording, filing, stamp or similar tax which may be payable in respect of any transfer involved in the issuance of, and the preparation and delivery of certificates (if applicable) representing, (i) any Exercise Shares purchased upon exercise of this Warrant and/or (ii) new or replacement warrants in the Holder’s name or the name of any transferee of all or any portion of this Warrant; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance, delivery or registration of any certificates for Exercise Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Exercise Shares upon exercise hereof.

2.4 EXERCISE LIMITATIONS; HOLDER’S RESTRICTIONS. A Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise, such Holder (together with such Holder’s affiliates), as set forth on the applicable Notice of Exercise, would beneficially own in excess of 9.9% of the number of shares of the Common Stock outstanding immediately after giving effect to such issuance. For purposes of this Section 2.4, the number of shares of Common Stock beneficially owned by such Holder and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by such Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other shares of Common Stock or Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2.4, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act, it being acknowledged by a Holder that the Company is not representing to such Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and such Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2.4 applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder) and of which a portion of this Warrant is exercisable shall be in the sole discretion of a Holder, and the submission of a Notice of Exercise shall be deemed to be each Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. For purposes of this Section 2.4, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Company’s Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by such Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The provisions of this Section 2.4 may be waived by such Holder, at the election of such Holder, upon not less than 61 days’ prior notice to the Company, and the provisions of this Section 2.4 shall continue to apply until such 61st day (or such later date, as determined by such Holder, as may be specified in such notice of waiver).

3. COVENANTS OF THE COMPANY.

3.1 COVENANTS AS TO EXERCISE SHARES. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens (other than those imposed by the Holder) and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

3.2 NO IMPAIRMENT. Except and to the extent as waived or consented to by the holder of the Warrants representing at least a majority of the number of shares of Common Stock then subject to outstanding Warrants, the Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment.

3.3 NOTICES OF RECORD DATE AND CERTAIN OTHER EVENTS. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least twenty (20) days prior to the date on which any such record is to be taken for the purpose of such dividend or distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall mail to the Holder, at least twenty (20) days prior to the date of the occurrence of any such event, a notice specifying such date. In the event the Company authorizes or approves, enters into any agreement contemplating, or solicits stockholder approval for any Fundamental Transaction, as defined in Section 6 herein, the Company shall mail to the Holder, at least twenty (20) days prior to the date of the occurrence of such event, a notice specifying such date.

B-5

4. ADJUSTMENT OF EXERCISE PRICE AND SHARES.

(A) In the event of changes in the outstanding Common Stock of the Company by reason of stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, consolidation, acquisition of the Company (whether through merger or acquisition of substantially all the assets or stock of the Company), or the like, the number, class and type of shares available under this Warrant in the aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of this Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and type of shares or other property as the Holder would have owned had this Warrant been exercised prior to the event and had the Holder continued to hold such shares until the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant.

(B) If at any time or from time to time the holders of all outstanding shares of Common Stock of the Company (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) pursuant to a dividend or distribution declared by the Company (other than a dividend or distribution covered in Section 4(A) above), shall have received or become entitled to receive, without payment therefor:

(I) Common Stock or any shares of stock or other securities which are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution;

(II) any cash paid or payable otherwise than as a cash dividend; or

(III) Common Stock or additional stock or other securities or property (including cash) by way of spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement, then and in each such case, the Holder hereof will, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clauses (II) and (III) above) which such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property.

B-6

(C) Upon the occurrence of each adjustment pursuant to this Section 4, the Company at its expense will, at the written request of the Holder, promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Exercise Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the transfer agent for the Warrants, if other than the Company.

5. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction.

6. FUNDAMENTAL TRANSACTIONS. If, at any time while this Warrant is outstanding, (i) the Company effects any merger of the Company with or into another entity and the Company is not the surviving entity, (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or by another individual or entity and approved by the Company) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares of Common Stock for other securities, cash or property or (iv) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 4 above) (in any such case, a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive the number of shares of Common Stock of the successor or acquiring corporation or of the Company and any additional consideration (the “Alternate Consideration”) receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event (disregarding any limitation on exercise contained herein solely for the purpose of such determination). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant consistent with the foregoing provisions and evidencing the Holder’s right to exercise such warrant into Alternate Consideration. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, then the Company or any successor entity shall at the Holder’s option, exercisable at any time concurrently with or within thirty (30) days after the consummation of the Fundamental Transaction, purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the value of this Warrant as determined in accordance with the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg L.P. using (i) a price per share of Common Stock equal to the Volume-Weighted Average Price of the Common Stock for the Trading Day immediately preceding the date of consummation of the applicable Fundamental Transaction, (ii) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of this Warrant as of the date of consummation of the applicable Fundamental Transaction and (iii) an expected volatility equal to the lesser of (1) the thirty (30) day volatility obtained from the “HVT” function on Bloomberg L.P. determined as of the end of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction or (2) 70%. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 6 and ensuring that this Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

B-7

7. NO STOCKHOLDER RIGHTS. Other than as provided in Section 3.3 or otherwise herein, this Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.

8. TRANSFER OF WARRANT. Subject to applicable laws and the restriction on transfer set forth in the Subscription Agreement, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. The transferee shall sign an investment letter in form and substance reasonably satisfactory to the Company and its counsel. Any proposed transfer of all or any portion of this Warrant in violation of the provisions of this warrant or the Subscription Agreement shall be null and void. Upon surrender of this Warrant and delivery of an assignment, the Company shall execute and deliver a new Warrant or Warrants in the name of the transferee or transferees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the transferor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled.

9. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company.

10. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at the address listed on the signature page hereto and to Holder at the applicable address set forth on the applicable signature page to the Subscription Agreement or at such other address as the Company or Holder may designate by ten (10) days advance written notice to the other parties hereto.

B-8

11. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

12. GOVERNING LAW. This Warrant and all rights, obligations and liabilities hereunder shall be governed by, and construed in accordance with, the internal laws of the State of New York, without giving effect to the principles of conflicts of law that would require the application of the laws of any other jurisdiction.

13. AMENDMENT OR WAIVER. Any term of this Warrant may be amended or waived (either generally or in a particular instance and either retroactively or prospectively) with the written consent of the Company and the holders of the Warrants representing at least two-thirds of the number of shares of Common Stock then subject to outstanding Warrants. Notwithstanding the foregoing, (a) this Warrant may be amended and the observance of any term hereunder may be waived without the written consent of the Holder only in a manner which applies to all Warrants in the same fashion and (b) the number of Exercise Shares subject to this Warrant and the Exercise Price of this Warrant may not be amended, and the right to exercise this Warrant may not be waived, without the written consent of the Holder. The Company shall give prompt written notice to the Holder of any amendment hereof or waiver hereunder that was effected without the Holder’s written consent. No waivers of any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

Re: American DG Energy Inc. Offering of Common Stock

Dear Sirs:

In order to induce Canaccord Genuity Inc. (“Canaccord”) to enter in to a certain placement agency agreement (the “Placement Agreement”) with American DG Energy Inc., a Delaware corporation (the “Company”), with respect to the public offering (the “Offering”) of shares of the Company’s Common Stock, par value $0.001 per share (“Common Stock”), the undersigned hereby agrees that for a period of ninety (90) days following the date of the Placement Agreement (the “lock-up period”), the undersigned will not, without the prior written consent of Canaccord, directly or indirectly, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, or announce the intention to otherwise dispose of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including, without limitation, shares of Common Stock or any such securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations promulgated under the Securities Act of 1933, as the same may be amended or supplemented from time to time (such shares or securities, the “Beneficially Owned Shares”), (ii) enter into any swap, hedge or other agreement or arrangement that transfers in whole or in part, the economic risk of ownership of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock, or (iii) engage in any short selling of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock.

If (i) the Company issues an earnings release or material news or a material event relating to the Company occurs during the last seventeen (17) days of the lock-up period, or (ii) prior to the expiration of the lock-up period, the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the lock-up period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the eighteen (18)-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless in either case Canaccord waives such provision in writing.

D-1

Notwithstanding the foregoing, the undersigned may transfer Beneficially Owned Shares (i) as a bona fide gift or gifts, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, or (iii) by will or intestate succession; provided, that in the case of each of clauses (i), (ii) and (iii) above, (A) each donee, transferee or distributee shall execute and deliver a letter substantially in the form hereof agreeing to be bound by the terms hereof and (B) neither the undersigned nor any other party to the applicable transaction shall be required to file, or voluntarily file, a report under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), other than a filing on Form 5 made after the expiration of the lock-up period, or, where the undersigned is required to file a report under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of Common Stock during the lock-up period (as the same may be extended as described above), only if the undersigned shall include a statement in such report to the effect that such transfer or distribution is not a transfer for value and, that such transfer is being made as a gift or by will or intestacy, as the case may be. For purposes of this agreement, the term “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.
