Item 1.01. Entry into a Material Definitive Agreement.

Securities Purchase Agreement

On September 29, 2010, EnteroMedics Inc. (the “Company”) entered into binding Securities Purchase Agreements (each, a “Securities Purchase Agreement”) for the sale of 3,394,309 shares of its Series A Non-Voting Convertible Preferred Stock (the “Preferred Stock”), together with warrants to purchase an aggregate of 3,394,309 shares of its common stock (the “Up Front Warrants”), in a private placement transaction with several accredited investors (the “Private Placement”). The purchase price per share of Preferred Stock was $1.72 (the “Original Purchase Price”), which equaled the consolidated closing bid price of the Company’s common stock as reported by the Nasdaq Stock Market on September 29, 2010. The Up Front Warrants will be exercisable at any time and from time to time beginning on the date that is six months and one day after the closing of the Private Placement. The Up Front Warrants have an exercise price of $2.15 per share, which equals 125% of the consolidated closing bid price of the Company’s common stock as reported by the Nasdaq Stock Market on September 29, 2010. The Up Front Warrants will become exercisable upon the later to occur of the following: (i) the date that is six months and one day after the issuance of the warrants, or (ii) the closing of an Equity Offering (as defined in Item 3.02 below). If the Preferred Stock converts into common stock upon completion of an Equity Offering in accordance with the terms of the Certificate of Designations for the Preferred Stock, each investor will purchase additional warrants from the Company (the “Conversion Warrants”) to purchase that number of shares of the Common Stock equal to (i) the difference between the Original Purchase Price and the price per share of Common Stock underlying the equity securities paid by investors in an Equity Offering (the “Equity Offering Purchase Price”), multiplied by the number of shares of Preferred Stock purchased by the investor, divided by (ii) the Conversion Warrant exercise price per share, which will equal $2.06 (120% of the Original Purchase Price). The Conversion Warrants will only be issued if the Company completes the Equity Offering and the Original Purchase Price is more than the Equity Offering Purchase Price. The purchase price for each warrant issued pursuant to the Securities Purchase Agreements equals $0.125 per share of common stock underlying the warrant. On September 30, 2010, EnteroMedics completed the final closing of the Private Placement.

Certain affiliates of the Company participated in the Private Placement on the terms set forth above, including certain investors affiliated with our directors as follows: MPM Capital Funds, of whom the Company’s director Luke Evnin is a managing director, acquired 704,607 shares of Preferred Stock, and warrants to acquire 704,607 shares of Common Stock; Bay City Capital, of whom the Company’s director Carl Goldfischer is a managing director, acquired 1,626,016 shares of Preferred Stock and warrants to acquire 1,626,016 shares of Common Stock; Aberdare Ventures, of whom the Company’s director Paul Klingenstein is a managing director, acquired 406,504 shares of Preferred Stock and warrants to acquire 406,504 shares of Common Stock; Charter Life Sciences, of whom the Company’s director Don Harrison is a managing director, acquired 216,802 shares of Preferred Stock and warrants to acquire 216,802 shares of Common Stock. In addition, Paul Klingenstein, a director of the Company, acquired 16,525 shares of Preferred Stock and warrants to acquire 16,525 shares of Common Stock, and Nick Teti, a director of the Company, acquired 10,840 shares of Preferred Stock and warrants to acquire 16,525 shares of Common Stock.

Pursuant to the Securities Purchase Agreement, the Company agreed to file a registration statement with the Securities and Exchange Commission (the “SEC”) within 45 days following completion of an Equity Offering (the “Required Filing Date”), registering for resale the shares of common stock issued upon conversion of the Preferred Stock and exercise of the warrants purchased by the Investors for an offering to be made on a continuous basis pursuant to Rule 415 promulgated by the SEC pursuant to the Securities Act of 1933, as amended (the “Securities Act”). The Company also agreed to use its best efforts, subject to receipt of necessary information from the investors, to cause the registration statement to become effective as soon as practicable after the registration statement is filed by the Company, but in any event no later than 4:00 p.m. Eastern Time on the 90th day after the Required Filing Date, or if the registration statement is reviewed by the SEC, on the 135th day after the Required Filing Date. The Company has agreed to maintain the registration statement’s effectiveness until the earlier of (i) the first anniversary of the Closing Date (such period of time to be extended by any period of time that the Shares are not listed for trading on the Nasdaq Stock Market), (ii) the date on which the registrable securities may be sold pursuant to Rule 144 without limitations on volume or manner of sales or (iii) such time as all registrable securities purchased by such Investor in the Private Placement have been sold pursuant to a registration statement or Rule 144.

The foregoing summary of the terms of the Securities Purchase Agreement and Warrants is subject to, and qualified in its entirety by, the Securities Purchase Agreement, which is attached to this Current Report on Form 8-K

as Exhibit 10.1 and incorporated herein by reference, and the form of Warrants attached to this Current Report on Form 8-K as Exhibit 10.2 and 10.3 and incorporated herein by reference. The description set forth above in Item 3.02 below is incorporated by reference.

Item 3.02. Unregistered Sales of Equity Securities.

On September 30, 2010, the Company completed the sale of an aggregate of 3,394,309 shares of Series A Non-Voting Convertible Preferred Stock, together with warrants to purchase an aggregate of 3,394,309 shares of Common Stock to certain accredited investors, for gross proceeds of approximately $6.3 million, less certain expenses. Each holder of Preferred Stock has the rights, preferences and duties set forth in the Certificate of Designations authorized by the Company’s board of directors and filed with the Secretary of State of the State of Delaware on September 29, 2010. The Preferred Stock has a par value of $0.01 per share and the board authorized an amount up to 3,600,000 shares. Each share of Preferred Stock has an original issue price of $1.72. As of the closing of the Private Placement, the Company had 19 shareholders of record of the Preferred Stock.

The Shares and the Warrants were offered and sold in the Private Placement to accredited investors without registration under the Securities Act, or the securities laws of certain states, in reliance on the exemptions provided by Section 4(2) of the Securities Act and Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws.

The following is a summary of certain material provisions of such certificate, which summary is qualified in its entirety by reference to the Certificate of Designation filed herewith as Exhibit 10.4.

Dividends. Dividends will be paid on the Preferred Stock on an as-converted basis when, as, and if paid on the Company’s Common Stock.

Liquidation Preference. In the event of any liquidation, dissolution or winding up of the Company, any distributions to holders of the Company’s outstanding equity shall be made as follows: First, to the holder of any share of Preferred Stock up to 150% of the Original Purchase Price plus declared and unpaid dividends on each share of Preferred Stock, and then pro rata to the holders of the Common Stock and Preferred Stock on an as converted basis.

No Voting Rights. Except as required by law or as otherwise set forth below the Preferred Stock shall be non-voting and shall not have any voting rights. So long as 10% of the shares of Preferred Stock are outstanding, in addition to any other vote or approval required under the Company’s Charter or By-laws, the Company will not, without the written consent of the holders of at least 75% of the Preferred Stock, either directly or by amendment, merger, consolidation, or otherwise: (i) create or authorize the creation of or issue any other security convertible into or exercisable for any equity security, having rights, preferences or privileges senior to or on parity with the Preferred Stock, or increase the authorized number of shares of Preferred Stock; or (ii) purchase or redeem or pay any dividend on any capital stock prior to the Preferred Stock, other than stock repurchased from former employees or consultants in connection with the cessation of their employment/services, at the lower of fair market value or cost; other than as approved by the Board.

Conversion Rights. The Preferred Stock may be converted on a 1:1 basis into shares of Common Stock at any time at the option of the Investor, subject to adjustments for stock dividends, splits, combinations and similar events; provided, however, that no investor will be permitted to convert an amount of Preferred Stock that would result in such investor owning more than 19.99% of the Company’s outstanding Common Stock upon such conversion.

Each share of Preferred Stock will automatically be converted on a 1:1 basis into shares of Common Stock (subject to adjustments for stock dividends, splits, combinations and similar events): (i) immediately after the closing of an offering by the Company of equity securities producing gross proceeds of at least $15 million excluding proceeds from the sale of Preferred Stock (the “Equity Offering”), or (ii) upon the written consent of the holders of 75% of the Preferred Stock; provided, however, that in the case of (i) and (ii) above, no Investor will be permitted to convert an amount of Preferred Stock that would result in such Investor owning more than 19.99% of the Company’s outstanding Common Stock upon such conversion.

Item 3.03. Material Modification to Rights of Securityholders.

The filing of the Company’s Certificate of Designations and the issuance of the Preferred Stock affect the holders of the Company’s common stock to the extent provided for in the Certificate of Designations, filed as an amendment to the Company’s certificate of incorporation with the Secretary of State of the State of Delaware on September 29, 2010. The summary of the Certificate of Designations, included above under Item 3.02 is qualified in its entirety by reference to the Certificate of Designations filed herewith as Exhibit 10.4. The additional information required to be provided in this Item 3.03 is included above under such Item 3.02 and below under Item 5.03.

Item 5.03. Amendment to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On September 29, 2010, the Company filed a Certificate of Designations (the “Certificate of Designations”) with the Delaware Secretary of State for the purpose of amending its Certificate of Incorporation to fix the designations, preferences, limitations and relative rights of its Preferred Stock. The Preferred Stock has a liquidation preference of $2.58 per share. The Certificate of Designations is attached hereto as 10.4 and is incorporated by reference herein.

3.1 Organization. The Company is duly incorporated and validly existing in good standing under the laws of the State of Delaware. The Company has full power and authority to own, operate and occupy its properties and to conduct its business as presently conducted and is registered or qualified to do business and in good standing in each jurisdiction in which it owns or leases property or transacts business and where the failure to be so qualified would have a material adverse effect upon the Company or the business, financial condition, properties, operations or assets of the Company and its subsidiaries as a whole or the Company’s ability to perform its obligations under the Agreements in all material respects (“Material Adverse Effect”). The Company has no “subsidiaries” (as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”)), other than EnteroMedics SARL, a Swiss corporation (the “Subsidiary”), all of the capital stock of which is owned by the Company. For purposes of Section 3 of this Agreement, the term “Company” shall be deemed to refer to both the Company and the Subsidiary, unless the context otherwise requires. The Company has good and marketable title in fee simple to, or has valid rights to lease or otherwise use, all items of real and personal property that are material to the business of the Company free and clear of all liens, encumbrances, claims and defects and imperfections of title except those that (i) do not materially interfere with the use of such property by the Company or (ii) would not reasonably be expected to have a Material Adverse Effect.

3.2 Due Authorization. The Company has all requisite power and authority to execute, deliver and perform its obligations under the Agreement, the Warrants and the Certificate of Designations (collectively, the “Transaction Documents”). The execution and delivery of the Transaction Documents, and the consummation by the Company of the transactions contemplated hereby, have been duly authorized by all necessary corporate action and no further action on the part of the Company or its Board of Directors or stockholders is required. The Agreement and Initial Securities have been, and the Conversion Warrants will upon issuance be, validly executed and delivered by the Company and constitute legal, valid and binding agreements of the Company enforceable against the Company in accordance with their terms, except to the extent (i) rights to indemnity and contribution may be limited by state or federal securities laws or the public policy underlying such laws, (ii) such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and (iii) such enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

3.3 Non-Contravention. The execution and delivery of the Transaction Documents, the issuance and sale of the Securities to be sold by the Company under the Transaction Documents, the fulfillment of the terms of the Transaction Documents and the consummation of the transactions contemplated thereby will not (A) result in conflict with or constitute a violation of, or default (with the passage of time or otherwise) under, (i) any bond, debenture, note or other evidence of indebtedness, or any material lease, contract, indenture, mortgage, deed of trust, loan agreement, joint venture or other agreement or instrument to which the Company is a party or by which the Company or the Subsidiaries or their respective properties are bound, except as would not reasonably be expected to have a Material Adverse Effect, (ii) the Certificate of Incorporation, by-laws or other organizational documents of the Company, as amended, or (iii) any law, administrative regulation, ordinance or order of any court or governmental agency, arbitration panel or authority binding upon the Company or its properties, except as would not reasonably be expected to have a Material Adverse Effect or (B) result in the creation or imposition of any lien, encumbrance, claim, security interest or restriction whatsoever upon any of the material properties or assets of the Company or an acceleration of indebtedness pursuant to any obligation, agreement or condition contained in any material bond, debenture, note or any other evidence

6

of indebtedness or any material indenture, mortgage, deed of trust or any other agreement or instrument to which the Company is a party or by which it is bound or to which any material property or assets of the Company is subject, except as would not reasonably be expected to have a Material Adverse Effect. No consent, approval, authorization or other order of, or registration, qualification or filing with, any regulatory body, administrative agency, or other governmental body is required for the execution and delivery of the Transaction Documents by the Company and the valid issuance or sale of the Securities by the Company pursuant to the Transaction Documents, other than such as have been made or obtained, and except for any filings required to be made under federal or state securities laws.

3.4 Capitalization. The outstanding capital stock of the Company as of June 30, 2010 is set forth on Schedule 3.4 of the Disclosure Schedules. The Company has not issued any capital stock since June 30, 2010 other than the exercise of outstanding warrants or stock options. The Securities to be sold pursuant to the Transaction Documents, as well as all shares of common stock issuable upon conversion of the Series A Preferred, have been duly authorized, and when issued and paid for in accordance with the terms of the Agreements, will be duly and validly issued, fully paid and nonassessable, subject to no lien, claim or encumbrance (except for any such lien, claim or encumbrance created, directly or indirectly, by the Investor). The Warrant Shares, when issued and paid for in accordance with the terms of the Warrants, will be duly and validly issued, fully paid and nonassessable, subject to no lien, claim or encumbrance (except for any such lien, claim or encumbrance created, directly or indirectly, by the Investor). The outstanding shares of capital stock of the Company have been duly and validly issued and are fully paid and nonassessable, have been issued in compliance with the registration requirements of federal and state securities laws, and were not issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. Except as set forth on Schedule 3.4 of the Disclosure Schedules and except as disclosed in the SEC Reports, there are no outstanding rights (including, without limitation, preemptive rights), warrants or options to acquire, or instruments convertible into or exchangeable for, any unissued shares of capital stock or other equity interest in the Company, or any contract, commitment, agreement, understanding or arrangement of any kind to which the Company is a party and providing for the issuance or sale of any capital stock of the Company, any such convertible or exchangeable securities or any such rights, warrants or options. Without limiting the foregoing, no preemptive right, co-sale right, registration right, right of first refusal or other similar right exists with respect to the issuance and sale of the Securities, except as provided in the Transaction Documents or except for such rights as may have been waived prior to the date of this Agreement. There are no shareholders agreements, voting agreements or other similar agreements with respect to the Common Stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s shareholders.

3.5 Legal Proceedings. There is no material legal, regulatory or governmental proceeding pending, or to the knowledge of the Company, threatened, to which the Company is a party or of which the business or property of the Company is subject that is required to be disclosed and that is not so disclosed in the SEC Reports. The Company is not subject to any injunction, judgment, decree or order of any court, regulatory body, administrative agency or other government body. Neither the Company, nor any director or officer thereof, is or has been the subject of any action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty relating to the Company. There has not been, and to the knowledge of the Company, there is not pending or contemplated, any investigation by the SEC or state securities commission involving the Company or any current or former director or officer of the Company. The Company has not received any stop order or other order suspending the effectiveness of any registration statement filed by the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or the Securities Act and, to the Company’s knowledge, the SEC has not issued any such order. There are no material disagreements presently existing, or reasonably anticipated by the Company to arise, between the independent accounting firms formerly or presently engaged by the Company.

(b) Except in the event that paragraph (c) below applies, the Company shall: (i) if deemed necessary by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not contain an 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, and so that, as thereafter delivered to purchasers of the Registrable Securities being sold thereunder, such Prospectus will not contain an 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, in light of the circumstances under which they were made, not misleading; (ii) provide the Investor copies of any documents filed pursuant to Section 6.2(b)(i); and (iii) upon request, inform each Investor who so requests that the Company has complied with its obligations in Section 6.2(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared effective, the Company will notify the Investor to that effect, will use its best efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly notify the Investor pursuant to Section 6.2(b)(i) hereof when the amendment has become effective).

(c) Subject to paragraph (d) below, in the event: (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to the Registration Statement or related Prospectus or for additional information; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) of any event or circumstance which necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it 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, and that in the case of the Prospectus, it 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, in the light of the circumstances under which they were made, not misleading; then the Company shall promptly deliver a certificate in writing to the Investor (the

14

“Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investor will refrain from selling any Shares pursuant to the Registration Statement (a “Suspension”) until the Investors are advised in writing by the Company that the current Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus. In the event of any Suspension, the Company will use its reasonable best efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable after delivery of a Suspension Notice to the Investors. In addition to and without limiting any other remedies (including, without limitation, at law or at equity) available to the Investor, the Investor shall be entitled to specific performance in the event that the Company fails to comply with the provisions of this Section 6.2(c).

(d) Notwithstanding the foregoing paragraphs of this Section 6.2, the Company shall use its commercially reasonable efforts to ensure that (i) a Suspension shall not exceed thirty (30) days individually, (ii) no more than two (2) Suspensions shall occur during any twelve month period and (iii) each Suspension shall be separated by a period of at least thirty (30) days from a prior Suspension (each Suspension that satisfies the foregoing criteria being referred to herein as a “Qualifying Suspension”). If a Suspension occurs and such Suspension is not a Qualifying Suspension (a “Non-Qualifying Suspension”), the Company shall, on the 10^th Business Day immediately following the effectiveness of the Non-Qualifying Suspension and each 30^th day thereafter, make a payment to the Investor as partial compensation for such Non-Qualifying Suspension equal to 1.5% of the purchase price paid for the Shares that are convertible into Registrable Securities purchased by the Investor and not previously sold by the Investor until the Non-Qualifying Suspension has ended; provided, however, that in no event shall the payments made pursuant to this paragraph (d), if any, exceed in the aggregate 5% of the purchase price paid by the Investor for the Shares that are convertible into Registrable Securities; provided, further, that in all events such penalties under this paragraph (d) shall cease to accrue with respect to any Investor on the date on which such Investor may sell Registrable Securities pursuant to Rule 144 without limitations on volume or manner of sales.

(e) If a Suspension is not then in effect, the Investor may sell Registrable Securities under the Registration Statement, provided that it complies with any applicable prospectus delivery requirements. Upon receipt of a request therefor, the Company will provide an adequate number of current Prospectuses to the Investor and to any other parties requiring such Prospectuses.

(f) In the event of a sale of Registrable Securities by the Investor, unless such requirement is waived by the Company in writing, the Investor must also deliver to the Company’s transfer agent, with a copy to the Company, a Certificate of Subsequent Sale substantially in the form attached hereto as Exhibit C, so that the securities may be properly transferred.

(g) The Company agrees that it shall, immediately prior to the Registration Statement being declared effective, deliver to its transfer agent an opinion letter of counsel, opining that at any time the Registration Statement is effective, the transfer agent shall issue, in connection with the sale of the Registrable Securities, certificates representing such securities without restrictive legend, provided the Registrable Securities are to be sold pursuant to the prospectus contained in the Registration Statement and the transfer agent receives a Certificate of Subsequent Sale in the form attached hereto as Exhibit C. Upon receipt of such opinion, the Company shall cause the transfer agent to confirm, for the benefit of the Investor, that no further opinion of counsel is required at the time of transfer in order to issue such Registrable Securities without restrictive legend.

The Company shall cause its transfer agent to issue a certificate without any restrictive legend to a purchaser of any Securities from the Investor, if (a) the sale of such Registrable Securities is registered under the Registration Statement (including registration pursuant to Rule 415

15

under the Securities Act) and the Investor has delivered a Certificate of Subsequent Sale to the Transfer Agent; (b) the holder has provided the Company with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Securities may be made without registration under the Securities Act; or (c) such Securities are sold in compliance with Rule 144 under the Securities Act. In addition, the Company shall, at the request of the Investor, remove the restrictive legend from any Shares held by the Investor following the expiration of the requirement for such restrictive legend under Rule 144 under the Securities Act (or any successor rule). Each Investor, severally and not jointly with the other Investors, agrees that such Investor will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if Securities are Registrable Securities held by an Investor that are sold pursuant to the Registration Statement, they will be sold in compliance with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates representing Securities as set forth in this Section 6.2 is predicated upon the Company’s reliance upon this understanding.

6.3 Securities Ineligible for Registration; Transfer Restrictions.

(a) Investors hereby acknowledge and agree that the Securities are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Investor must hold the Securities (including shares of common stock issuable upon conversion or exercise thereof) indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Investors acknowledge that the Company has no obligation to register or qualify any of the Securities (including shares of common stock issuable upon conversion or exercise thereof) for resale, except for the registration rights in Sections 6.1 and 6.2 hereof which pertain only to the Investors and only with respect to Securities which qualify as Registrable Securities. The Investors further acknowledge that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of the Investor’s control.

(b) Subject to Section 6.2(g) above, the Investors agree to the imprinting on any of the Securities in the following form:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

16

The Company acknowledges and agrees that an Investor may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and, if required under the terms of such arrangement, such Investor may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Investors’ expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including, if the Securities are subject to registration rights with the SEC, the preparation and filing of any required prospectus supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder.

6.4 Indemnification. For the purpose of this Section 6.4:

(a) the term “Selling Stockholder” shall mean the Investor and each person, if any, who controls the Investor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act;

(b) the term “Registration Statement” shall include any final Prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Registration Statement (or deemed to be a part thereof) referred to in Section 6.1; and

(c) the term “untrue statement” shall mean any untrue statement or alleged untrue statement, or any omission or alleged omission to state in the Registration Statement a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) (i) The Company agrees to indemnify and hold harmless each Selling Stockholder from and against any losses, claims, damages or liabilities to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon (i) any untrue statement of a material fact contained in the Registration Statement, (ii) any inaccuracy in the representations and warranties of the Company contained in the Agreement or the failure of the Company to perform its obligations hereunder or (iii) any failure by the Company to fulfill any undertaking included in the Registration Statement, and the Company will reimburse such Selling Stockholder for any reasonable legal expense or other actual accountable out of pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Selling Stockholder specifically for use in preparation of the Registration Statement, or any inaccuracy in representations made by such Selling Stockholder in the Investor Questionnaire or the failure of such Selling Stockholder to comply with its covenants and agreements contained in Sections 4.1, 4.2, 4.3, 4.4 or 6.2 hereof or any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder.

(ii) The Investor agrees to indemnify and hold harmless the Company (and each person, if any, who controls the Company within the meaning of Section 15 of the

17

Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company) from and against any losses, claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, (i) any failure to comply with the covenants and agreements contained in Section 4.1, 4.2, 4.3, 4.4 or 6.2 hereof, or (ii) any untrue statement of a material fact contained in the Registration Statement if, and only if, such untrue statement was made in reliance upon and in conformity with written information furnished by or on behalf of the Investor specifically for use in preparation of the Registration Statement, and the Investor will reimburse the Company (or such officer, director or controlling person), as the case may be, for any reasonable legal expense or other actual accountable out-of-pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim. The obligation to indemnify shall be limited to the net amount of the proceeds received by the Investor from the sale of the Shares pursuant to the Registration Statement.

(iii) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 6.4, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 6.4 (except to the extent that such omission materially and adversely affects the indemnifying party’s ability to defend such action) or from any liability otherwise than under this Section 6.4. Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof (unless it has failed to assume the defense thereof and appoint counsel reasonably satisfactory to the indemnified party), such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the reasonable opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided that such consent shall not be unreasonably withheld. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could reasonably have been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(iv) If the indemnification provided for in this Section 6.4 is unavailable to or insufficient to hold harmless an indemnified party under subsection (d)(i) or (d)(ii) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Investor on the other in connection with the statements or omissions or other matters which resulted in

18

such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or the Investor on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and the Investor agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Investors were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (d)(iv). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Investor shall not be required to contribute any amount in excess of the amount by which the net amount received by the Investor from the sale of the Shares to which such loss relates exceeds the amount of any damages which the Investor has otherwise been required to pay by reason of such untrue statement. 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 Investors’ obligations in this subsection to contribute are several in proportion to their sales of Shares to which such loss relates and not joint.

The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 6.4, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 6.4 fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement as required by the Securities Act and the Exchange Act.

6.5 Termination of Conditions and Obligations. The conditions precedent imposed by Section 4 or this Section 6 upon the transferability of the Securities shall cease and terminate as to any particular number of the Shares when such Shares shall have been effectively registered under the Securities Act and sold or otherwise disposed of in accordance with the intended method of disposition set forth in the Registration Statement covering such Shares or at such time as an opinion of counsel satisfactory to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act.

6.6 Information Available. So long as the Registration Statement is effective covering the resale of Registrable Securities owned by the Investor, the Company will furnish (or, to the extent such information is available electronically through the Company’s filings with the SEC, the Company will make available) to the Investor:

(a) as soon as practicable after it is available, one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain consolidated financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants) and (ii) if not included in substance in the Annual Report to Stockholders, its Annual Report on Form 10-K (the foregoing, in each case, excluding exhibits);

(b) upon the reasonable request of the Investor, all exhibits excluded by the parenthetical to subparagraph (a)(ii) of this Section 6.6 as filed with the SEC and all other information that is made available to shareholders; and

19

(c) upon the reasonable request of the Investor, an adequate number of copies of the Prospectuses to supply to any other party requiring such Prospectuses; and the Company, upon the reasonable request of the Investor, will meet with the Investor or a representative thereof at the Company’s headquarters during the Company’s normal business hours to discuss all information relevant for disclosure in the Registration Statement covering the Registrable Securities and will otherwise reasonably cooperate with the Investor conducting an investigation for the purpose of reducing or eliminating the Investor’s exposure to liability under the Securities Act, including the reasonable production of information at the Company’s headquarters; provided, that the Company shall not be required to disclose any confidential information to or meet at its headquarters with the Investor until and unless the Investor shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Company with the Company with respect thereto.

6.7 Public Statements. By 7:30 a.m., Eastern time, on the trading day immediately following the execution of this Agreement, the Company shall issue one or more press releases disclosing all material terms of the transactions contemplated hereby. The Company agrees to disclose on a Current Report on Form 8-K the existence of the Offering and the material terms, thereof, including pricing, within one (1) Business Day after the Closing. Such Current Report on Form 8-K shall include a form of this Agreement as an exhibit thereto. The Company will not issue any public statement, press release or any other public disclosure listing the Investor as one of the purchasers of the Securities without the Investor’s prior written consent, except as may be required by applicable law or rules of any exchange on which the Company’s securities are listed.

7. Notices. All notices, requests, consents and other communications hereunder shall be in writing, shall be delivered (A) if within the United States, by first-class registered or certified airmail, or nationally recognized overnight express courier, postage prepaid, or by facsimile, or (B) if from outside the United States, by International Federal Express (or comparable service) or facsimile, and shall be deemed given (i) if delivered by first-class registered or certified mail domestic, upon the Business Day received, (ii) if delivered by nationally recognized overnight carrier, one (1) Business Day after timely delivery to such carrier, (iii) if delivered by International Federal Express (or comparable service), two (2) Business Days after so mailed, (iv) if delivered by facsimile, upon electric confirmation of receipt and shall be addressed as follows, or to such other address or addresses as may have been furnished in writing by a party to another party pursuant to this paragraph:

The overall commitment of

FORM OF LEGAL OPINION

September 29, 2010

To: The Purchasers of Series A Non-Voting Convertible Preferred Stock of EnteroMedics Inc.

Ladies and Gentlemen:

Reference is hereby made to the several Securities Purchase Agreements, dated as of the date hereof (the “Agreement”), by and among EnteroMedics Inc., a Delaware corporation (the “Company”), and each person identified as an Investor therein (collectively, the “Investors”). Unless otherwise defined herein, capitalized terms used herein shall have the meanings assigned to them in the Agreement.

We have acted as counsel to the Company in connection with the issuance under the Agreement of up to 3,394,309 shares of the Company’s Series A Non-Voting Convertible Preferred Stock, $0.01 par value per share, Up Front Warrants to purchase up to 3,394,309 shares of the Company’s Common Stock, $0.01 par value per share and the Conversion Warrants. This opinion is being delivered to you pursuant to Section 2 of the Agreement.

We have examined such documents and have reviewed such questions of law as we have considered necessary or appropriate for the purpose of this opinion.

In rendering our opinions, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures and the conformity to authentic originals of all documents submitted to us as copies. We have also assumed the legal capacity for all purposes relevant hereto of all natural persons and, with respect to all parties to agreements or instruments relevant hereto other than the Company, that such parties had the requisite power and authority (corporate or otherwise) to execute, deliver and perform such agreements or instruments, that such agreements or instruments have been duly authorized by all requisite action (corporate or otherwise) on behalf of such parties, executed and delivered by such parties and that such agreements or instruments are the valid, binding and enforceable obligations of such parties. As to questions of fact material to our opinions, we have relied upon certificates of officers of the Company, including certificates being delivered to you at the Closing.

Our opinions expressed below as to certain factual matters are qualified as being limited “to our knowledge” or by other words to the same or similar effect. Such words, as used herein, mean the information known to Kenneth L. Cutler, Timothy S. Hearn, Michael W. Clausman and Jenna L. Hannigan, the attorneys in this firm who have represented the Company in connection with the matters addressed herein. In rendering such opinions, we have not consulted with other attorneys in our firm with respect to the matters covered thereby,

1

and we have conducted no review of documents in our files relating to any other matters in which this firm has represented the Company. No inference as to our knowledge with respect to such matters should be drawn from the fact of our representation of the Company.

On the basis of the foregoing and of our examination of such other questions of law and fact as we deem relevant under the circumstances, and in reliance thereon, and subject to the limitations, qualifications, presumptions and exceptions set forth herein, we are of the opinion that:

Based on the foregoing, we are of the opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware, with the corporate power to conduct any lawful business activity. The Company has the corporate power to execute, deliver and perform the Agreement including, without limitation, the issuance and sale of the Shares, the Warrants and, upon due exercise by the Investors of the Warrants, the issuance and sale of the Warrant Shares.

2. The Transaction Documents have been duly authorized by all requisite corporate action, executed and delivered by the Company. The Transaction Documents constitute the valid and binding agreement of the Company enforceable in accordance with their terms.

3. As of the date hereof, the authorized capital stock of the Company consists of 85,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share, of which 3,600,000 shares have been designated as Series A Non-Voting Convertible Preferred Stock.

4. The execution, delivery and performance of the Transaction Documents and the issuance and sale of the Securities in accordance with the Agreement will not: (a) violate or conflict with, or result in a breach of or default under, the Certificate of Incorporation or by-laws of the Company, (b) violate or conflict with, or constitute a default under any material agreement or instrument (limited, with your consent, to agreements filed with the Securities and Exchange Commission under the Exchange Act and applicable rules and regulations) to which the Company is a party, or (c) violate any law of the United States or the State of Delaware, any rule or regulation of any governmental authority or regulatory body of the United States or the State of Delaware or any judgment, order or decree known to us and applicable to the Company of any court, governmental authority or arbitrator.

5. To our knowledge, no consent, approval, authorization or order of, and no notice to or filing with, any governmental agency or body or any court is required to be obtained or made by the Company for the issue and sale of the Securities pursuant to the Agreement, except such as have been obtained or made and such as may be required under the federal securities laws or the Blue Sky laws of the various states.

6. Assuming the representations made by the Investors and the Company set forth in the Agreement are true and correct, the offer, sale, issuance and delivery of the Securities to the Investors, in the manner contemplated by the Agreement, does not need to be registered under the Securities Act, it being understood that no opinion is expressed as to any subsequent resale of such shares.

2

7. We know of no pending or overtly threatened lawsuit or claim against the Company which is required to be described in the reports filed or required to be filed by the Company with the Securities and Exchange Commission under the Exchange Act.

8. The issuance of the Securities, in accordance with the Agreement, does not require approval of the Company’s stockholders pursuant to Nasdaq Marketplace Rule 5635(d).

The opinions set forth above are subject to the following qualifications and exceptions:

(a) Our opinions in paragraph 2 above are subject to the effect of (i) any applicable bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent transfer or other similar law affecting creditors’ rights generally and (ii) principles of equity, including (without limitation) concepts of materiality, reasonableness, good faith and fair dealing, election of remedies, estoppel and other similar doctrines affecting the enforceability of agreements generally (regardless of whether considered in a proceeding in equity or at law).

(b) Our opinions in paragraph 2 above, insofar as they relate to indemnification provisions, are subject to the effect of federal and state securities laws and public policy relating thereto.

(c) We express no opinion as to the compliance or the effect of noncompliance by the Investors with any state or federal laws or regulations applicable to the Investors in connection with the transactions described in the Agreement.

Our opinions expressed above are limited to the laws of the State of Minnesota, the Delaware General Corporation Law and the federal laws of the United States of America.

We express no opinion regarding the accuracy of any financial representations in the Agreement or the financial status of the Company.

The foregoing opinion is given solely for your benefit, speaks only as of the date hereof, may not be relied upon by any other person or entity and shall not be copied or distributed to any other person or entity without our prior express written consent. We specifically disclaim any obligation to inform you of any change in law, facts or circumstances which may be brought to our attention subsequent to the date hereof.

Very truly yours,

(herein called the “Company”), a corporation organized and existing under the laws of the State of Delaware, at the exercise price specified in the Agreement [(subject to adjustment as noted below)],                      (                     )¹ fully paid and nonassessable shares (“Shares”) of common stock (herein the “Common Stock”) (subject to the limitation in Section 2(b) and to adjustment as noted below). This Warrant may only be exercised during the Exercise Period specified herein. This Warrant has been issued pursuant to a Securities Purchase Agreement, dated as of September 29, 2010 (the “Agreement”), between the Purchaser and the Company.

The warrant exercise price (subject to adjustment as noted below) shall be $2.15² per Share (the “Warrant Purchase Price”).

This Warrant is subject to the following provisions, terms and conditions:

1. The Warrant exercise period (the “Exercise Period”) for this Warrant shall begin on the later to occur of (a) the date that is 181 days from the date of the issuance of this Warrant and (b) the date on which the Equity Offering commences (as defined in the Agreement), and shall end on the fifth anniversary of the date on which the Exercise Period begins.

¹ Equal to number of Series A Non–Voting Convertible Preferred shares purchased by Purchaser.

² Equal to 125% of the original purchase price paid for Series A Non–Voting Convertible Preferred.

2. The rights represented by this Warrant may be exercised by the holder hereof as follows:

(a) The rights represented by this Warrant may be exercised by the holder hereof, in whole or in part, by written notice of exercise delivered to the Company and by the surrender of this Warrant (properly endorsed if required) at the principal office of the Company and upon payment to it by check of the Warrant Purchase Price for such Shares. The Company agrees that the Shares so purchased shall be and are deemed to be issued to the holder hereof as the record owner of such Shares as of the close of business on the date on which this Warrant shall have been surrendered and payment made for such Shares as aforesaid. Subject to the provisions of the next succeeding paragraph, within 10 business days after the rights represented by this Warrant shall have been exercised the Company shall cause its transfer agent to issue the Shares of stock so purchased to Purchaser in book–entry format and deliver evidence of such issuance to Purchaser, and, unless this Warrant has expired, a new Warrant representing the number of Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be delivered to the holder hereof within such time.

(b) Notwithstanding any other provision in this Warrant, no holder shall be permitted to exercise this Warrant for an amount of Common Stock that would result in such holder owning more than 19.99% of the Company’s Common Stock outstanding after such exericise.

3. The Company represents and warrants that this Warrant has been duly authorized by all necessary corporate action, has been duly executed and delivered and is a legal and binding obligation of the Company, enforceable against the Company in accordance with the terms of this Warrant, except to the extent (i) such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and (ii) such enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). The Company covenants and agrees that all Shares which may be issued upon the exercise of the rights represented by this Warrant according to the terms hereof or represented by the Common Stock will, upon issuance and payment therefor, be duly authorized and issued, fully paid and nonassessable. The Company further covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of issue or transfer upon exercise of the subscription rights evidenced by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant, free from preemptive rights or other actual contingent purchase rights other than those held by a holder of this Warrant (as a result of holding this Warrant).

4. The Company will pay any documentary stamp taxes attributable to the issuance of Shares of Common Stock upon the exercise 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

2

involved in the registration of any certificates for Warrants, or shares of Common Stock issued upon exercise of this Warrant, in a name other than that of the Purchaser. The Purchaser shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Shares of Common Stock upon exercise hereof.

5. The above provisions are, however, subject to the following:

(a) The Warrant Purchase Price shall, from and after the date of issuance of this Warrant, be subject to adjustment from time to time as hereinafter provided. Upon each adjustment of the Warrant Purchase Price, the holder of this Warrant shall thereafter be entitled to purchase, at the Warrant Purchase Price resulting from such adjustment, the number of Shares obtained by multiplying the Warrant Purchase Price in effect immediately prior to such adjustment by the number of Shares purchasable pursuant hereto immediately prior to such adjustment and dividing the product thereof by the warrant purchase price resulting from such adjustment.

(b) In case the Company shall (i) declare a dividend upon the Common Stock payable in Common Stock (other than a dividend declared to effect a subdivision of the outstanding shares of Common Stock, as described in subparagraph (c) below) or any obligations or any shares of stock of the Company which are convertible into or exchangeable for Common Stock (such obligations or shares of stock being hereinafter referred to as “Convertible Securities”), or in any rights or options to purchase any Common Stock or Convertible Securities, or (ii) declare any other dividend or make any other distribution upon the Common Stock payable otherwise than out of earnings or earned surplus, then thereafter the holder of this Warrant upon the exercise hereof will be entitled to receive the number of shares of Common Stock to which such holder shall be entitled upon such exercise, and, in addition and without further payment therefor, such number of shares of Common Stock, such that upon exercise hereof, such holder would receive such number of shares of Common Stock as a result of each dividend described in clause (i) above and each dividend or distribution described in clause (ii) above which such holder would have received by way of any such dividend or distribution if continuously since the record date for any such dividend or distribution such holder (i) had been the record holder of the number of shares of Common Stock then received, and (ii) had retained all dividends or distributions in stock or securities (including Common Stock or Convertible Securities, or in any rights or options to purchase any Common Stock or Convertible Securities) payable in respect of such Common Stock or in respect of any stock or securities paid as dividends or distributions and originating directly or indirectly from such Common Stock. For the purposes of the foregoing, a dividend or distribution other than in cash shall be considered payable out of earnings or surplus only to the extent that such earnings or surplus are charged an amount equal to the fair value of such dividend as determined by the Board of Directors of the Company.

(c) In case the Company shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares, the Warrant Purchase Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Common Stock of the Company shall be combined into a smaller number of shares, the Warrant Purchase Price in effect immediately prior to such combination shall be proportionately increased.

3

(d) If any capital reorganization or reclassification of the capital stock of the Company, shall be effected in such a way that holders of Common Stock shall be entitled to receive stock or securities with respect to or in exchange for Common Stock, then, as a condition of such reorganization, reclassification or consolidation, lawful and adequate provision shall be made whereby the holder hereof shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in this Warrant and in lieu of the Shares of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby, such shares of stock or securities as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby had such reorganization, reclassification or consolidation not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the holder of this Warrant to the end that the provisions hereof (including without limitation provisions for adjustments of the warrant purchase price and of the number of shares purchasable upon the exercise of this Warrant) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock or securities thereafter deliverable upon the exercise hereof.

(e) Upon any adjustment of the Warrant Purchase Price or any adjustment of any material terms hereof, then and in each such case an officer of the Company shall, as soon as practicable after the occurrence of any event that requires an adjustment or readjustment, give signed written notice thereof, by first–class mail, postage prepaid, addressed to the registered holder of this Warrant at the address of such holder as shown on the books of the Company, which notice shall state the Warrant Purchase Price resulting from such adjustment, any material change in the terms of the Warrant, and the increase or decrease, if any, in the number of Shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

(f) In case any time:

(i) the Company shall declare any cash dividend on its capital stock at a rate in excess of the rate of the last cash dividend theretofore paid;

(ii) the Company shall pay any dividend payable in stock upon its capital stock or make any distribution (other than regular cash dividends) to the holders of its capital stock;

(iii) there shall be any capital reorganization, or reclassification of the capital stock of the Company; or

(iv) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company;

4

then, in any one or more of said cases, the Company shall give written notice, by first–class mail, postage prepaid, addressed to the registered holder of this Warrant at the address of such holder as shown on the books of the Company, of the date on which (A) the books of the Company shall close or a record shall be taken for such dividend, distribution or subscription rights, or (B) such reorganization, reclassification or consolidation, dissolution, liquidation or winding up, or conversion or redemption shall take place, as the case may be. Such notice shall also specify the date as of which the holders of capital stock of record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their capital stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, dissolution, liquidation or winding up, or conversion or redemption, as the case may be. Such written notice shall be given at least 20 days prior to the action in question and not less than 20 days prior to the record date or the date on which the Company’s transfer books are closed in respect thereto.

(g) If any event occurs as to which in the opinion of the Board of Directors of the Company the other provisions of this Section 5 are not strictly applicable or if strictly applicable would not fairly protect the purchase rights of the holder of this Warrant or of Common Stock in accordance with the essential intent and principles of such provisions, then the Board of Directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such purchase rights as aforesaid.

6. This Warrant shall not entitle the holder hereof to any voting rights or other rights as a stockholder of the Company.

7. The holder of this Warrant, by acceptance hereof, agrees to give written notice to the Company before transferring this Warrant or transferring any Common Stock issuable or issued upon the exercise hereof of such holder’s intention to do so, describing briefly the manner of any proposed transfer of this Warrant or such holder’s intention as to the disposition to be made of shares of Common Stock issuable or issued upon the exercise hereof. Such holder shall also provide the Company with an opinion of counsel satisfactory to the Company to the effect that the proposed transfer of this Warrant or disposition of shares may be effected without registration or qualification (under any Federal or State law) of this Warrant or the shares of Common Stock issuable or issued upon the exercise hereof. Upon receipt of such written notice and opinion by the Company, such holder shall be entitled to transfer this Warrant, or to exercise this Warrant in accordance with its terms and dispose of the shares received upon such exercise or to dispose of shares of Common Stock received upon the previous exercise of this Warrant, all in accordance with the terms of the notice delivered by such holder to the Company, provided that an appropriate legend respecting the aforesaid restrictions on transfer and disposition may be endorsed on this Warrant or the certificates for such shares.

8. Subject to the provisions of paragraph 7 hereof, this Warrant and all rights hereunder are transferable, in whole or in part, at the principal office of the Company by the holder hereof in person or by duly authorized attorney, upon surrender of this Warrant properly endorsed. Each taker and holder of this Warrant, by taking or holding the same, consents and

5

agrees that the bearer of this Warrant, when endorsed, may be treated by the Company and all other persons dealing with this Warrant as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented by this Warrant, or to the transfer hereof on the books of the Company, any notice to the contrary notwithstanding; but until such transfer on such books, the Company may treat the registered holder hereof as the owner for all purposes.

9. This Warrant is exchangeable, upon the surrender hereof by the holder hereof at the principal office of the Company, for new Warrants of like tenor representing in the aggregate the right to subscribe for and purchase the number of shares which may be subscribed for and purchased hereunder, each of such new Warrants to represent the right to subscribe for and purchase such number of shares as shall be designated by said holder hereof at the time of such surrender.

10. The holder hereby acknowledge and agree that this Warrant constitutes a “restricted security” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the holder must hold the Warrant (including Shares of Common Stock issuable upon exercise hereof) indefinitely unless they are registered with the U.S. Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The holder acknowledges that, except as set forth in the Agreement, the Company has no obligation to register or qualify the Warrant (including Shares of Common Stock issuable upon exercise thereof) for resale. This Warrant and the Shares shall be imprinted with a legend in substantially the form set forth in Section 6.3(b) of Annex A to the Securities Purchase Agreement.

11. All questions concerning this Warrant will be governed and interpreted and enforced in accordance with the internal law, not the law of conflicts, of the State of Delaware.

(herein called the “Company”), a corporation organized and existing under the laws of the State of Delaware, at the exercise price specified in the Agreement (subject to adjustment as noted below),                      (                     )¹ fully paid and nonassessable shares (“Shares”) of common stock (herein the “Common Stock”) (subject to the limitation in Section 2(b) and to adjustment as noted below). This Warrant may only be exercised during the Exercise Period specified herein. This Warrant has been issued pursuant to a Securities Purchase Agreement, dated as of September 29, 2010 (the “Agreement”), between the Purchaser and the Company.

The warrant exercise price (subject to adjustment as noted below) shall be $2.06² per Share (the “Warrant Purchase Price”).

This Warrant is subject to the following provisions, terms and conditions:

1. The Warrant exercise period (the “Exercise Period”) for this Warrant shall begin on the date that is 181 days from the date of the issuance of this Warrant and shall end on the fifth anniversary of the date on which the Exercise Period begins.

¹ Equal to the difference between the original purchase price paid for Series A Non–Voting Convertible Preferred and the per share price paid for Common Stock in the Equity Offering, multiplied by the number of shares of Series A Non–Voting Convertible Preferred purchased by Purchaser, divided by the Warrant Purchase Price.

² Equal to 120% of the original purchase price paid for Series A Non–Voting Convertible Preferred.

2. The rights represented by this Warrant may be exercised by the holder hereof as follows:

(a) The rights represented by this Warrant may be exercised by the holder hereof, in whole or in part, by written notice of exercise delivered to the Company and by the surrender of this Warrant (properly endorsed if required) at the principal office of the Company and upon payment to it by check of the Warrant Purchase Price for such Shares. The Company agrees that the Shares so purchased shall be and are deemed to be issued to the holder hereof as the record owner of such Shares as of the close of business on the date on which this Warrant shall have been surrendered and payment made for such Shares as aforesaid. Subject to the provisions of the next succeeding paragraph, within 10 business days after the rights represented by this Warrant shall have been exercised the Company shall cause its transfer agent to issue the Shares of stock so purchased to Purchaser in book–entry format and deliver evidence of such issuance to Purchaser, and, unless this Warrant has expired, a new Warrant representing the number of Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be delivered to the holder hereof within such time.

(b) Notwithstanding any other provision in this Warrant, no holder shall be permitted to exercise this Warrant for an amount of Common Stock that would result in such holder owning more than 19.99% of the Company’s Common Stock outstanding after such exercise.

3. The Company represents and warrants that this Warrant has been duly authorized by all necessary corporate action, has been duly executed and delivered and is a legal and binding obligation of the Company, enforceable against the Company in accordance with the terms of this Warrant, except to the extent (i) such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and (ii) such enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). The Company covenants and agrees that all Shares which may be issued upon the exercise of the rights represented by this Warrant according to the terms hereof or represented by the Common Stock will, upon issuance and payment therefor, be duly authorized and issued, fully paid and nonassessable. The Company further covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of issue or transfer upon exercise of the subscription rights evidenced by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant, free from preemptive rights or other actual contingent purchase rights other than those held by a holder of this Warrant (as a result of holding this Warrant).

4. The Company will pay any documentary stamp taxes attributable to the issuance of Shares of Common Stock upon the exercise of this Warrant; provided, however, that the

2

Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrants, or shares of Common Stock issued upon exercise of this Warrant, in a name other than that of the Purchaser. The Purchaser shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Shares of Common Stock upon exercise hereof.

5. The above provisions are, however, subject to the following:

(a) The Warrant Purchase Price shall, from and after the date of issuance of this Warrant, be subject to adjustment from time to time as hereinafter provided. Upon each adjustment of the Warrant Purchase Price, the holder of this Warrant shall thereafter be entitled to purchase, at the Warrant Purchase Price resulting from such adjustment, the number of Shares obtained by multiplying the Warrant Purchase Price in effect immediately prior to such adjustment by the number of Shares purchasable pursuant hereto immediately prior to such adjustment and dividing the product thereof by the warrant purchase price resulting from such adjustment.

(b) In case the Company shall (i) declare a dividend upon the Common Stock payable in Common Stock (other than a dividend declared to effect a subdivision of the outstanding shares of Common Stock, as described in subparagraph (c) below) or any obligations or any shares of stock of the Company which are convertible into or exchangeable for Common Stock (such obligations or shares of stock being hereinafter referred to as “Convertible Securities”), or in any rights or options to purchase any Common Stock or Convertible Securities, or (ii) declare any other dividend or make any other distribution upon the Common Stock payable otherwise than out of earnings or earned surplus, then thereafter the holder of this Warrant upon the exercise hereof will be entitled to receive the number of shares of Common Stock to which such holder shall be entitled upon such exercise, and, in addition and without further payment therefor, such number of shares of Common Stock, such that upon exercise hereof, such holder would receive such number of shares of Common Stock as a result of each dividend described in clause (i) above and each dividend or distribution described in clause (ii) above which such holder would have received by way of any such dividend or distribution if continuously since the record date for any such dividend or distribution such holder (i) had been the record holder of the number of shares of Common Stock then received, and (ii) had retained all dividends or distributions in stock or securities (including Common Stock or Convertible Securities, or in any rights or options to purchase any Common Stock or Convertible Securities) payable in respect of such Common Stock or in respect of any stock or securities paid as dividends or distributions and originating directly or indirectly from such Common Stock. For the purposes of the foregoing, a dividend or distribution other than in cash shall be considered payable out of earnings or surplus only to the extent that such earnings or surplus are charged an amount equal to the fair value of such dividend as determined by the Board of Directors of the Company.

(c) In case the Company shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares, the Warrant Purchase Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Common Stock of the Company shall be combined into a smaller number of shares, the Warrant Purchase Price in effect immediately prior to such combination shall be proportionately increased.

3

(d) If any capital reorganization or reclassification of the capital stock of the Company, shall be effected in such a way that holders of Common Stock shall be entitled to receive stock or securities with respect to or in exchange for Common Stock, then, as a condition of such reorganization, reclassification or consolidation, lawful and adequate provision shall be made whereby the holder hereof shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in this Warrant and in lieu of the Shares of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby, such shares of stock or securities as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby had such reorganization, reclassification or consolidation not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the holder of this Warrant to the end that the provisions hereof (including without limitation provisions for adjustments of the warrant purchase price and of the number of shares purchasable upon the exercise of this Warrant) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock or securities thereafter deliverable upon the exercise hereof.

(e) Upon any adjustment of the Warrant Purchase Price or any adjustment of any material terms hereof, then and in each such case an officer of the Company shall, as soon as practicable after the occurrence of any event that requires an adjustment or readjustment, give signed written notice thereof, by first–class mail, postage prepaid, addressed to the registered holder of this Warrant at the address of such holder as shown on the books of the Company, which notice shall state the Warrant Purchase Price resulting from such adjustment, any material change in the terms of the Warrant, and the increase or decrease, if any, in the number of Shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

(f) In case any time:

(i) the Company shall declare any cash dividend on its capital stock at a rate in excess of the rate of the last cash dividend theretofore paid;

(ii) the Company shall pay any dividend payable in stock upon its capital stock or make any distribution (other than regular cash dividends) to the holders of its capital stock;

(iii) there shall be any capital reorganization, or reclassification of the capital stock of the Company; or

(iv) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company;

4

then, in any one or more of said cases, the Company shall give written notice, by first–class mail, postage prepaid, addressed to the registered holder of this Warrant at the address of such holder as shown on the books of the Company, of the date on which (A) the books of the Company shall close or a record shall be taken for such dividend, distribution or subscription rights, or (B) such reorganization, reclassification or consolidation, dissolution, liquidation or winding up, or conversion or redemption shall take place, as the case may be. Such notice shall also specify the date as of which the holders of capital stock of record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their capital stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, dissolution, liquidation or winding up, or conversion or redemption, as the case may be. Such written notice shall be given at least 20 days prior to the action in question and not less than 20 days prior to the record date or the date on which the Company’s transfer books are closed in respect thereto.

(g) If any event occurs as to which in the opinion of the Board of Directors of the Company the other provisions of this Section 5 are not strictly applicable or if strictly applicable would not fairly protect the purchase rights of the holder of this Warrant or of Common Stock in accordance with the essential intent and principles of such provisions, then the Board of Directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such purchase rights as aforesaid.

6. This Warrant shall not entitle the holder hereof to any voting rights or other rights as a stockholder of the Company.

7. The holder of this Warrant, by acceptance hereof, agrees to give written notice to the Company before transferring this Warrant or transferring any Common Stock issuable or issued upon the exercise hereof of such holder’s intention to do so, describing briefly the manner of any proposed transfer of this Warrant or such holder’s intention as to the disposition to be made of shares of Common Stock issuable or issued upon the exercise hereof. Such holder shall also provide the Company with an opinion of counsel satisfactory to the Company to the effect that the proposed transfer of this Warrant or disposition of shares may be effected without registration or qualification (under any Federal or State law) of this Warrant or the shares of Common Stock issuable or issued upon the exercise hereof. Upon receipt of such written notice and opinion by the Company, such holder shall be entitled to transfer this Warrant, or to exercise this Warrant in accordance with its terms and dispose of the shares received upon such exercise or to dispose of shares of Common Stock received upon the previous exercise of this Warrant, all in accordance with the terms of the notice delivered by such holder to the Company, provided that an appropriate legend respecting the aforesaid restrictions on transfer and disposition may be endorsed on this Warrant or the certificates for such shares.

8. Subject to the provisions of paragraph 7 hereof, this Warrant and all rights hereunder are transferable, in whole or in part, at the principal office of the Company by the holder hereof in person or by duly authorized attorney, upon surrender of this Warrant properly endorsed. Each taker and holder of this Warrant, by taking or holding the same, consents and

5

agrees that the bearer of this Warrant, when endorsed, may be treated by the Company and all other persons dealing with this Warrant as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented by this Warrant, or to the transfer hereof on the books of the Company, any notice to the contrary notwithstanding; but until such transfer on such books, the Company may treat the registered holder hereof as the owner for all purposes.

9. This Warrant is exchangeable, upon the surrender hereof by the holder hereof at the principal office of the Company, for new Warrants of like tenor representing in the aggregate the right to subscribe for and purchase the number of shares which may be subscribed for and purchased hereunder, each of such new Warrants to represent the right to subscribe for and purchase such number of shares as shall be designated by said holder hereof at the time of such surrender.

10. The holder hereby acknowledge and agree that this Warrant constitutes a “restricted security” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the holder must hold the Warrant (including Shares of Common Stock issuable upon exercise hereof) indefinitely unless they are registered with the U.S. Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The holder acknowledges that, except as set forth in the Agreement, the Company has no obligation to register or qualify the Warrant (including Shares of Common Stock issuable upon exercise thereof) for resale. This Warrant and the Shares shall be imprinted with a legend in substantially the form set forth in Section 6.3(b) of Annex A to the Securities Purchase Agreement.

11. All questions concerning this Warrant will be governed and interpreted and enforced in accordance with the internal law, not the law of conflicts, of the State of Delaware.

CERTIFICATE OF DESIGNATIONS

FOR

SERIES A NON–VOTING CONVERTIBLE PREFERRED STOCK

(PURSUANT TO DELAWARE GENERAL CORPORATION LAW,

SECTION 151(G))

The undersigned, being the Chief Financial Officer, Vice President and Secretary of EnteroMedics Inc. (the “Corporation”), a corporation organized and existing under the Delaware General Corporation Law, in accordance with the provisions of the Delaware General Corporation Law, Section 151(g), do hereby certify that:

Pursuant to the authority vested in the Board of Directors of the Corporation by the Fifth Amended and Restated Certificate of Incorporation of the Corporation, the Board of Directors of the Corporation on September 9, 2010, in accordance with the Delaware General Corporation Law, Section 151, duly adopted the following resolution establishing a series of 3,600,000 shares of the Corporation’s Preferred Stock, to be designated as its Series A Non–Voting Convertible Preferred Stock:

RESOLVED, that pursuant to the authority vested in the Board of Directors of the Corporation (the “Board of Directors”) by the Fifth Amended and Restated Certificate of Incorporation of the Corporation, the Board of Directors hereby establishes a series of Series A Non–Voting Convertible Preferred Stock of the Corporation and hereby states the number of shares and fixes the powers, designations, preferences and relative, participating, optional and other rights, and the qualifications, limitations and restrictions thereof, of such series of shares as follows:

SERIES A NON–VOTING CONVERTIBLE PREFERRED STOCK

Section 1. Designation; Number of Shares. The shares of such series shall be designated as “Series A Non–Voting Convertible Preferred Stock” (the “Convertible Preferred Stock”), and the number of shares constituting the Convertible Preferred Stock shall be 3,600,000. Such number of shares may be decreased by resolution of the Board of Directors adopted and filed pursuant to the Delaware General Corporation Law, Section 151(g), or any successor provision; provided, that no such decrease shall reduce the number of authorized shares of Convertible Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, warrants, convertible or exchangeable securities or other rights to acquire shares of Convertible Preferred Stock.

Section 2. Stated Capital. The amount to be represented in the stated capital of the Corporation for each share of Convertible Preferred Stock shall be $0.01.

Section 3. Rank. The Convertible Preferred Stock shall rank prior to all of the Corporation’s Common Stock, par value $0.01 per share (the “Common Stock”), now outstanding or hereafter issued, as to distributions of assets upon the liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary.

Section 4. Dividends. So long as any shares of Convertible Preferred Stock remain outstanding, if the Corporation makes any dividend or distribution of cash, securities (including, but not limited to, rights, warrants, options or evidences of indebtedness) or properties or assets on shares of Common Stock, then the Corporation shall simultaneously declare and pay a dividend or distribution on shares of Convertible Preferred Stock in the amount of dividends or distributions that would be made with respect to shares of Convertible Preferred Stock if such shares were converted into shares of Common Stock on the record date for such dividend or distribution (or if no record date is established, at the date such dividend or distribution is declared).

Section 5. Liquidation Preference. In the event of a liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the holders of Convertible Preferred Stock shall be entitled to receive out of the assets of the Corporation, whether such assets constitute stated capital or surplus of any nature, an amount equal to the dividends accumulated and unpaid thereon to the date of final distribution to such holders, whether or not declared, without interest, plus a sum equal to $2.58 per share, and no more, before any payment shall be made or any assets distributed to the holders of Common Stock or any other capital stock of the Corporation ranking junior as to liquidation rights to the Convertible Preferred Stock (such Common Stock and other capital stock being referred to herein collectively as “Junior Liquidation Stock.” After payment in full of the liquidation preference of the shares of the Convertible Preferred Stock, the entire remaining assets and funds of the Corporation legally available for distribution, if any, shall be distributed among the holders of the Common Stock and the Convertible Preferred Stock in proportion to the shares of Common Stock then held by them and the shares of Common Stock which they then have the right to acquire upon conversion of the shares of Convertible Preferred Stock then held by them. A merger or consolidation (other than one in which stockholders of the Corporation own a majority by voting power of the outstanding shares of the surviving or acquiring corporation) and a sale, lease, transfer, exclusive license or other disposition of all or substantially all of the assets of the Corporation shall be deemed a liquidation, dissolution or winding up of the Corporation for purposes of this Section 5, thereby triggering payment of the liquidation preferences described above, unless the holders of 75% of the Convertible Preferred Stock elect otherwise.

Section 6. No Redemption. The shares of Convertible Preferred Stock shall not be redeemable.

2

Section 7. Conversion.

(a) Conversion at Option of Holders.

(i) Subject to the limitation set forth in Section 7(e), holders of Convertible Preferred Stock may, at their option upon surrender of the certificates therefor, convert any or all of their shares of Convertible Preferred Stock into fully paid and nonassessable shares of Common Stock (and such other securities and property as they may be entitled to, as hereinafter provided) at any time after issuance thereof. Each share of Convertible Preferred Stock shall be convertible at the office of any transfer agent for the Convertible Preferred Stock, and at such other office or offices, if any, as the Board of Directors may designate, into that number of fully paid and nonassessable shares of Common Stock as shall be equal to the Conversion Rate, determined as hereinafter provided, in effect at the time of conversion. Shares of Convertible Preferred Stock may initially be converted into full shares of Common Stock as is determined by dividing (A) the Original Issue Price by (B) the sum of the Original Issue Price plus the Conversion Price, subject to adjustment from time to time as provided in Section 8 (such conversion rate, as so adjusted from time to time, being referred to herein as the “Conversion Rate”). “Original Issue Price” means $1.72. “Conversion Price” means $0.125 multiplied by the sum of the number of shares of Common Stock issuable under the converting holder’s Conversion Warrant (as defined in that certain Securities Purchase Agreement, dated as of the date hereof, between the Corporation and the investors purchasing Convertible Preferred Stock pursuant thereto (the “Securities Purchase Agreement”) divided by the number of Convertible Preferred Stock held by such converting holder. Upon conversion, no adjustment or payment shall be made in respect of accumulated and unpaid dividends on the Convertible Preferred Stock surrendered for conversion.

(ii) The right of holders of Convertible Preferred Stock to convert their shares shall be exercised by surrendering for such purpose to the Corporation or its agent, as provided above, certificates representing shares to be converted, duly endorsed in blank or accompanied by proper instruments of transfer. The Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of Common Stock or other securities or property upon conversion of Convertible Preferred Stock in a name other than that of the holder of the shares of Convertible Preferred Stock being converted, nor shall the Corporation shall be required to issue or deliver any such shares or other securities or property unless and until the person or persons requesting the issuance thereof shall have paid to the Corporation the amount of any such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

(b) Mandatory Conversion. Subject to the limitation set forth in Section 7(e), each share of Convertible Preferred Stock shall be automatically converted into shares of Common Stock at the then effective Conversion Rate (i) upon the date on which at least 75% of the outstanding shares of Convertible Preferred Stock elect such conversion or (ii) upon the closing of an offering of equity securities for the account of the Corporation (other than by sale of the Convertible Preferred Stock pursuant to the Securities Purchase Agreement), provided that the aggregate gross proceeds to the Corporation are $15 million or more (net of underwriting commissions and expenses) (an “Equity Offering”), provided further that the Convertible Preferred Stock shall not be deemed to have converted until immediately after the closing of the Equity Offering.

3

(c) A number of shares of the authorized but unissued Common Stock sufficient to provide for the conversion of the Convertible Preferred Stock outstanding upon the basis hereinbefore provided shall at all times be reserved by the Corporation, free from preemptive rights, for such conversion, subject to the provisions of the next paragraph. If the Corporation shall issue any securities or make any change in its capital structure which would change the number of shares of Common Stock into which each share of the Convertible Preferred Stock shall be convertible as herein provided, the Corporation shall at the same time also make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of the outstanding Convertible Preferred Stock on the new basis. The Corporation shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of the Convertible Preferred Stock.

(d) Upon the surrender of certificates representing shares of Convertible Preferred Stock to be converted, duly endorsed or accompanied by proper instruments of transfer as provided above, the person converting such shares shall be deemed to be the holder of record of the Common Stock issuable upon such conversion, and all rights with respect to the shares surrendered shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets as herein provided.

(e) Notwithstanding any other provision of this Section 7, no stockholder of the Corporation’s capital stock shall be permitted to convert an amount of Convertible Preferred Stock that would result in such stockholder owning more than 19.99% of the Common Stock outstanding after such conversion.

Section 8. Adjustments to Conversion Rate.

(a) Notwithstanding anything in this Section 8 to the contrary, no change in the Conversion Rate shall be made until the cumulative effect of the adjustments called for by this Section 8 since the date of the last change in the Conversion Rate would change the Conversion Rate by more than 3%. However, once the cumulative effect would result in such a change, then the Conversion Rate shall be changed to reflect all adjustments called for by this Section 8 and not previously made. Subject to the foregoing, the Conversion Rate shall be adjusted from time to time as follows:

(i) In case the Corporation shall (A) pay a dividend or make a distribution on its Common Stock in shares of its capital stock, (B) subdivide its outstanding Common Stock into a greater number of shares, (C) combine the shares of its outstanding Common Stock into a smaller number of shares or (D) issue by reclassification of its Common Stock any shares of its capital stock, then in each such case the Conversion Rate in effect immediately prior thereto shall be proportionately adjusted so that the holder of any Convertible Preferred Stock thereafter surrendered for conversion shall be entitled to receive, to the extent permitted by applicable law, the number and kind of shares of capital stock of the Corporation which such holder would have owned or have been entitled to receive after the happening of such event had such Convertible Preferred Stock been converted immediately prior to the record date for such event (or if no record date is

4

established in connection with such event, the effective date for such action). An adjustment pursuant to this subparagraph (a)(ii) shall become effective immediately after the record date in the case of a stock dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification.

(b) Except as otherwise provided above in this Section 8, no adjustment in the Conversion Rate shall be made in respect of any conversion for share distributions or dividends theretofore declared and paid or payable on the Common Stock.

(c) Whenever the Conversion Rate is adjusted as herein provided, the Corporation shall send to each transfer agent for the Convertible Preferred Stock and the Common Stock, and to the NASDAQ Capital Market, a statement signed by the Chairman of the Board of Directors, the President or any Vice President of the Corporation and by its Treasurer or its Secretary stating the adjusted Conversion Rate determined as provided in this Section 8; and any adjustment so evidenced, given in good faith, shall be binding upon all stockholders and upon the Corporation. Whenever the Conversion Rate is adjusted, the Corporation shall give notice by mail at the time of, and together with, the next dividend payment to the holders of record of Convertible Preferred Stock, setting forth the adjustment and the new Conversion Rate and Conversion Price. Notwithstanding the foregoing notice provisions, failure by the Corporation to give such notice or a defect in such notice shall not affect the binding nature of such corporate action of the Corporation.

(d) Whenever the Corporation shall propose to take any of the actions specified in subparagraphs (a)(i) or (a)(ii) of this Section 8 which would result in any adjustment in the Conversion Rate, the Corporation shall cause a notice to be mailed at least 30 days prior to the date on which the books of the Corporation will close or on which a record will be taken for such action to the holders of record of the outstanding Convertible Preferred Stock on the date of such notice. Such notice shall specify the action proposed to be taken by the Corporation and the date as of which holders of record of the Common Stock shall participate in any such actions or be entitled to exchange their Common Stock for securities or other property, as the case may be. Failure by the Corporation to give such notice or any defect in such notice shall not affect the validity of the transaction.

Section 9. Convertible Preferred Stock Not Redeemable at Option of Holders or Exchangeable; No Sinking Fund. The Convertible Preferred Stock shall not be redeemable upon the request of holders thereof or exchangable for other capital stock or indebtedness of the Corporation or other property. The shares of Convertible Preferred Stock shall not be subject to the operation of a purchase, retirement or sinking fund.

Section 10. Voting Rights. The holders of Convertible Preferred Stock shall not have any voting rights except as set forth below in Section 11 or as otherwise from time to time required by law.

Section 11. Certain Actions Not to be Taken Without Vote of Holders of Convertible Preferred Stock. So long as 10% of the shares of Convertible Preferred Stock are outstanding, in addition to any other vote or approval required under the Fifth Amended and Restated Certificate of Incorporation of the Corporation or the Amended and Restated Bylaws of the Corporation, the Corporation will not, without the written consent of the holders of at least 75% of the Convertible Preferred Stock, either directly or by amendment, merger, consolidation or otherwise (i) create or authorize the creation of or issue any other security convertible into or exercisable for any equity security, having rights, preferences or privileges senior to or on parity with the Convertible Preferred Stock, or increase the authorized number of shares of Convertible Preferred Stock or (ii) purchase or redeem or pay any dividend on any capital stock prior to the Convertible Preferred Stock other than stock repurchased from former employees or consultants in connection with the cessation of their employment or services, as the case may be, at the lower of fair market value or cost, other than as approved by the Board of Directors.

Section 12. Outstanding Shares. For purposes of this Certificate of Designations, all shares of Convertible Preferred Stock shall be deemed outstanding except for (a) shares of Convertible Preferred Stock held of record or beneficially by the Corporation or any subsidiary of the Corporation; (b) from the date of surrender of certificates representing Convertible Preferred Stock for conversion pursuant to Section 7, all shares of Convertible Preferred Stock which have been converted into Common Stock or other securities or property pursuant to Section 7.
