Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

EnteroMedics Inc.

St. Paul, Minnesota

We have audited the accompanying
consolidated balance sheets of EnteroMedics Inc. and subsidiary (a development stage company) (the Company) as of December 31, 2007 and 2006, and the related consolidated statements of operations, stockholders equity
(deficit), and cash flows for each of the three years in the period ended December 31, 2007, and for the period from December 19, 2002 (date of inception) to December 31, 2007. These financial statements are the responsibility of the
Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Companys internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2007 and 2006, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 2007, and for the period from December 19, 2002 (date of inception) to December 31, 2007, in conformity with accounting principles generally accepted in the
United States of America.

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2006, the Company adopted
the provisions of Financial Accounting Standards Board Statement No. 123(R), Share-Based Payment.

EnteroMedics Inc.

(A development stage company)

Notes to Consolidated Financial Statements



|(1) | Formation and Business of the Company
|--- | -------------------------------------

EnteroMedics
Inc. (EnteroMedics or the Company) is developing implantable systems to treat obesity and other gastrointestinal disorders. The Company was incorporated in the state of Minnesota on December 19, 2002, originally as two separate legal entities,
Alpha Medical, Inc. (Alpha) and Beta Medical, Inc. (Beta), both of which were owned 100% by a common stockholder. Effective October 1, 2003, the two entities were combined and changed its name to EnteroMedics Inc. The Company changed its state
of incorporation to Delaware on July 22, 2004. The Company is in the development stage and since inception has devoted substantially all of its resources to recruiting personnel, developing its product technology, obtaining patents to protect
its intellectual property and raising capital, and has not derived revenues from its primary business activity. Accordingly, the Company is in the development stage, as defined by Statement of Financial Accounting Standards No. 7, Accounting
and Reporting by Development Stage Enterprises. The Company is headquartered in St. Paul, Minnesota.

EnteroMedics Europe Sárl
(EnteroMedics Europe), a wholly-owned subsidiary of the Company, was formed in January 2006. EnteroMedics Europe is a Switzerland entity established as a means to conduct clinical trials in Switzerland. Upon establishment there were 20 shares of
EnteroMedics Europe issued and outstanding with a par value of 1,000 Swiss Francs. EnteroMedics purchased 100% of the shares and then issued one share to a fiduciary agent. The one share is the property of EnteroMedics and is held by the fiduciary
in a fiduciary capacity under terms of the Fiduciary Agreement. Pursuant to Statement of Financial Accounting Standards No. 52, Foreign Currency Translation, the functional currency of EnteroMedics Europe has been determined to be the
U.S. Dollar.

In November 2007, the Company effected a 1-for-9.1 reverse split of its common stock and convertible preferred stock which
has been retroactively applied to these consolidated financial statements. Also, in November 2007, the Company completed its initial public offering of common stock (IPO), issuing a total of 5,489,849 shares for net proceeds of approximately $39.1
million after expenses and underwriters discounts and commissions, and including the exercise of the underwriters over-allotment option.

Since inception, EnteroMedics has incurred losses through December 31, 2007 totaling approximately $63.4 million and has not generated positive cash flows from operations. The Company expects such losses to
continue into the foreseeable future as it continues to develop and commercialize its technologies. The Company may need to obtain additional financing and there can be no assurance that the Company will be successful in obtaining additional
financing on favorable terms, or at all. If adequate funds are not available, the Company may have to delay development or commercialization of products or license to third parties the rights to commercialize products or technologies that the
Company would otherwise seek to commercialize.



|(2) | Summary of Significant Accounting Policies
|--- | ------------------------------------------

Basis of Presentation

The Company has prepared the accompanying consolidated financial statements in conformity with
accounting principles generally accepted in the United States of America. The Companys fiscal year ends on December 31.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted
in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Notes to Consolidated Financial Statements
(Continued)



Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany transactions and accounts have
been eliminated in consolidation.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and
short-term investments. Cash and cash equivalents are deposited in demand and money market accounts at two financial institutions. At times, such deposits may be in excess of insured limits. Investments in short-term money market funds are not
considered to be bank deposits and are not insured or guaranteed by the federal deposit insurance company or other government agency. These money market funds seek to preserve the value of the investment at $1.00 per share; however, it is possible
to lose money investing in these funds. The Company has not experienced any losses on its deposits of cash and cash equivalents.

Most of
the products developed by the Company will require clearance from the U.S. Food and Drug Administration (FDA) or corresponding foreign regulatory agencies prior to commercial sales. There can be no assurance the Companys products will
receive the necessary clearances. If the Company is denied clearance or clearance is delayed, it will have a material adverse impact on the Company.

The medical device industry is characterized by frequent and extensive litigation and administrative proceedings over patent and other intellectual property rights. Whether a product infringes a patent involves
complex legal and factual issues, the determination of which is often difficult to predict, and the outcome may be uncertain until the court has entered final judgment and all appeals are exhausted. The Companys competitors may assert that its
products or the use of the Companys products are covered by U.S. or foreign patents held by them.

Fair Value of Financial
Instruments

Carrying amounts of certain of the Companys financial instruments, including cash and cash equivalents, prepaid
expenses and other current assets, accounts payable and accrued liabilities approximate fair value due to their short maturities. The fair values of investments in debt and equity securities are disclosed in Note 3. The fair value of the
Companys long-term debt is approximately $12,125,000 as of December 31, 2007 based on the present value of estimated future cash flows using a discount rate commensurate with borrowing rates available to the Company.

Cash and Cash Equivalents

The
Company considers highly liquid investments with maturities of 90 days or less when purchased to be cash equivalents. Cash equivalents are stated at cost, which approximates market value. The Companys cash equivalents are primarily in money
market funds and commercial paper. The Company deposits its cash and cash equivalents in high-quality credit institutions. Under terms of the Companys notes payable agreements (see Note 6), in the event of default, the lender has the
right to enforce account control agreements and restrict the Companys access to their cash and investment accounts.

Short-Term
Investments

The Company considers all investments with maturities greater than three months and less than one year at the time of
purchase as short-term investments and classifies them as either available for sale or held to maturity.

Available-for-sale securities are
carried at fair value based on quoted market prices, with the unrealized gains and losses included in other comprehensive income within stockholders equity (deficit) in the consolidated



12

(Continued)



balance sheets. Realized gains and losses and declines in value judged to be other than temporary on available-for-sale securities are included in interest
and other income. Interest and dividends on securities classified as available for sale are included in interest income. The cost of securities sold is based on the specific identification method.

Short-term investments in debt securities which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for
premiums and discounts that are recognized in interest income, using the interest method, over the period to maturity. Unrealized losses on held-to-maturity securities reflecting a decline in value determined to be other than temporary are charged
to income.

Property and Equipment, Net

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment is computed using the straight-line method over their estimated useful lives of three to
seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of their useful life or the term of the lease. Upon retirement or sale, the cost and related accumulated depreciation are removed from the consolidated
balance sheets and the resulting gain or loss is reflected in the consolidated statements of operations. Repairs and maintenance are expensed as incurred.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets for impairment by
comparison of the carrying amounts to future net undiscounted cash flows expected to be generated by such assets when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Should an impairment exist, the
impairment loss would be measured based on the excess carrying value of the asset over the assets fair value or estimates of future discounted cash flows. The Company has not identified any such impairment losses to date.

Income Taxes

Income taxes are
accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities
and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance for deferred income tax assets is recorded
when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The Company has provided a full valuation allowance against the gross deferred tax assets as of December 31, 2007 and 2006 (see
Note 9). The Companys policy is to classify interest and penalties related to income taxes as income tax expense in the consolidated statements of operations.

Research and Development Expenses

Research and development expenses are charged to expense as
incurred. Research and development expenses include, but are not limited to, product development, clinical and regulatory expenses, payroll and other personnel expenses, materials, supplies, and consulting costs.

Patent Costs

Costs associated with the submission of a patent application are expensed as incurred given the uncertainty of the patents resulting in probable future
economic benefits to the Company. Patent-related legal expenses included in general and administrative costs were $378,362, $274,665 and $214,300 for the years ended December 31, 2007, 2006 and 2005, respectively, and $1,009,586 for the period
from December 19, 2002 (inception) to December 31, 2007.

Derivative Instruments

The Company accounts for the Series C preferred stock warrants as derivatives under Statement of Financial Accounting Standards No. 133,
Accounting for Derivative Instruments and Hedging Activities, and related Emerging Issues Task Force (EITF) interpretations and Securities and Exchange Commission (SEC) rules, which require that the warrants be classified as a liability and
measured at fair value with changes in fair value recognized currently in earnings, when there are not enough authorized shares to be issued upon exercise of the warrants. The Company has recorded changes in fair value as an other expense in the
consolidated statements of operations.

Stock-Based Compensation

Prior to January 1, 2006, the Company accounted for stock-based employee compensation arrangements in accordance with the provisions of Accounting
Principles Board Opinion No. 25 (APB 25),Accounting for Stock Issued to Employees, and related interpretations, and followed the minimum value disclosure provisions of Statement of Financial Accounting Standards No. 123 (SFAS
123),Accounting for Stock-Based Compensation. Under APB 25, compensation expense is based on the difference, if any, on the date of the grant, between the fair value of the Companys stock and the exercise price. Employee
stock-based compensation determined under APB 25 is recognized over the option vesting period.

Effective January 1, 2006, the
Company adopted the fair value provisions of Statement of Financial Accounting Standards No. 123R (SFAS 123R),Share-Based Payment, which supersedes its previous accounting under APB 25. SFAS 123R requires the recognition of
compensation expense, using a fair-value-based method, for costs related to all share-based payments including stock options. SFAS 123R requires companies to estimate the fair value of share-based payment awards on the date of grant using an
option-pricing model. The Company adopted SFAS 123R using the prospective transition method, which requires that for nonpublic entities that used the minimum value method for either pro forma or financial statement recognition purposes,
SFAS 123R shall be applied to option grants or modifications to existing options after the required effective date. For options granted prior to the new SFAS 123R effective date and for which the requisite service period has not been
performed as of January 1, 2006, the Company will continue to apply the intrinsic value provisions of APB 25 on the remaining unvested awards. All option grants valued after January 1, 2006 will be expensed on a straight-line basis over
the vesting period.

The Company accounts for stock-based compensation arrangements with nonemployees in accordance with the Emerging
Issues Task Force Abstract No. 96-18,Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling Goods or Services. The Company records the expense of such services based on
the estimated fair value of the equity instrument using the Black-Scholes pricing model. The value of the equity instrument is charged to earnings over the term of the service agreement.

Net Loss Per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss
per share is based on the weighted-average common shares outstanding during the period plus dilutive potential common shares calculated using the treasury stock method. Such potentially dilutive shares are excluded when the effect would be to reduce
a net loss per share. The Companys potential dilutive shares, which include outstanding common stock options, unvested common shares subject to repurchase, convertible preferred stock and warrants, have not been included in the computation of
diluted net loss per share for all periods as the result would be anti-dilutive.

The following table sets forth the computation of basic
and diluted net loss per share for the years ended December 31, 2007, 2006 and 2005:

Recently Issued Accounting Standards

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (SFAS 157),Fair Value Measurements, which defines
fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. SFAS 157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various
prior accounting pronouncements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. Earlier adoption is permitted, provided the company has not yet issued financial statements, including for interim periods, for that
fiscal year. The Company is currently evaluating the impact of SFAS 157.

Notes to Consolidated Financial Statements
(Continued)



In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159
(SFAS 159), The Fair Value Option for Financial Assets and Financial LiabilitiesIncluding an amendment of FASB Statement No. 115. SFAS 159 permits entities to choose to measure many financial instruments and certain other
items at fair value. The amendment to SFAS 115 applies to all entities with investments in available-for-sale or trading securities. The statement is effective for fiscal years beginning after November 15, 2007. The Company is
currently evaluating the impact of SFAS 159.

In June 2007, the FASB issued Emerging Issues Task Force No. 07-3 (EITF 07-3),
Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities. EITF 07-3 requires nonrefundable advance payments for goods or services that will be used or rendered for
future research and development activities to be deferred and capitalized. The expense should be recognized as the related goods are delivered or the related services are performed. The statement is effective prospectively for new contracts entered
into during fiscal years beginning after December 15, 2007.

In December 2007, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 110 (SAB 110). SAB 110 permits, under certain circumstances, the continued use of the simplified method in developing an estimate of the expected term of plain vanilla share options in accordance
with Statement of Financial Accounting Standards No. 123R, Share-Based Payment, beyond December 31, 2007. The Company currently uses the simplified method as there is not enough historical experience to provide a
reasonable estimate of the expected term and will continue to do so until there is enough historical experience in accordance with SAB110. The Company does not expect SAB 110 to have a material impact on the consolidated financial statements.

|(7) | Series C Convertible Preferred Stock Financing
|--- | ----------------------------------------------

On
July 6, 2006, the Company closed the Series C convertible preferred stock (Series C) financing. The Company sold 4,921,142 shares of Series C stock for $8.0926 per share, or total gross proceeds of $39,825,003. In addition, $5,250,003 of
Convertible Notes Payable principal and $131,013 of accrued interest payable were converted into 664,919 shares of Series C stock. The Company incurred $2,222,342 in financing costs, which were recorded as a reduction to additional paid-in capital.
Included in the Series C financing costs was $735,438 of value related to 147,635 Series C warrants issued to the private placement underwriter. The fair value of the warrants was calculated using a Black-Scholes valuation model and the following
assumptions: volatility of 55%, dividend rate of 0%, risk-free interest rate of 5.18%, and the maximum seven-year warrant life. The fair value of the warrants was recorded in additional paid-in capital. In accordance with the agreement, upon the
closing of the IPO, the warrants were converted into warrants to purchase common stock, with all other terms unchanged.

On
December 11, 2006, the Company sold an additional 123,569 shares of Series C stock for $8.0926 per share, or total gross proceeds of $1,000,000.

As of the closing date of the additional sale of 123,569 shares of Series C stock, the Company had insufficient authorized and unissued Series C stock available to share settle the Series C warrants which required

the instrument to be accounted for under Statement of Financial Accounting Standards No. 133 and classified as a liability in accordance with EITF
00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Companys Own Stock. The fair market value of the warrant as of December 31, 2006 was $728,841. The change in fair value is recorded
separately in the consolidated statements of operations.

On May 14, 2007 the Company filed an amended certificate of incorporation to
increase the number of authorized shares of Series C stock to 6,043,956. As a result of the amendment, the Company had sufficient authorized and unissued shares of Series C stock available to share settle the Series C warrants. The fair market value
of the warrants on May 14, 2007 was determined to be $1,090,345. The change in fair value from December 31, 2006 to the amendment date of $361,504 was recorded as expense and the convertible preferred stock liability was reclassified to
additional paid-in capital.



|(8) | Convertible Preferred Stock

In assessing the realization of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences
become deductible.

Based on the level of historical taxable losses and projections of future taxable income (losses) over the periods in
which the deferred tax assets can be realized, management currently believes that it is more likely than not that the Company will not realize the benefits of these deductible differences. Accordingly, the Company has provided a valuation allowance
against the gross deferred tax assets as of December 31, 2007 and 2006.

As of December 31, 2007, the Company has U.S. federal
net operating loss carryforwards of approximately $43,739,000. The federal net operating loss carryforwards expire in the years 2022 through 2027.

Federal tax laws impose significant restrictions on the utilization of net operating loss carryforwards and research and development credits in the event of a change in ownership of the Company, as defined by the Internal Revenue Code
Section 382. The Companys net operating loss carryforwards and research and development credits may be subject to the above limitations.

The Company adopted the provisions of FASB Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes, on January 1, 2007. Implementation of FIN 48 resulted in no adjustment to the
Companys liability for unrecognized tax benefits. As of both the date of adoption, and as of December 31, 2007, there were no unrecognized tax benefits. Accordingly, a tabular reconciliation from beginning to ending periods
is not provided. The Company will classify any future interest and penalties as a component of income tax expense if incurred. To date, there have been no interest or penalties charged or accrued in relation to unrecognized tax
benefits.

The Company is subject to federal and state examinations for the years 2004 forward. There are no tax examinations currently in
progress.

Stock-Based Compensation for Nonemployees

Stock-based compensation expenses related to stock options granted to nonemployees is recognized as the stock options are earned. The Company believes
that the fair value of the stock options is more reliably measurable than the fair value of the services received. The fair value of the stock options granted is calculated at each reporting date, using the Black-Scholes option-pricing model, until
the award vests or there is a substantial disincentive for the nonemployee not to perform the required services. The fair value for the years ended December 31, 2007, 2006 and 2005 was calculated using the following assumptions:

the intrinsic value method in accordance with the provisions of APB 25, and (b) compensation cost for all stock-based payments granted or modified subsequent to December 31, 2005, based on the grant-date fair value estimated in
accordance with the provisions of SFAS 123R.

Under SFAS 123R, compensation cost for employee stock-based awards is based on the
estimated grant-date fair value and is recognized over the vesting period of the applicable award on a straight-line basis. The weighted average estimated fair value of the employee stock options granted for the years ended December 31, 2007
and 2006 was $4.51 and $0.68 per share, respectively.

The Company uses the Black-Scholes pricing model to determine the fair value of
stock options. The determination of the fair value of stock-based payment awards on the date of grant is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include our expected
stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rates and expected dividends. The estimated grant-date fair values of the employee stock options were calculated
using the Black-Scholes valuation model, based on the following assumptions for the years ended December 31, 2007 and 2006:

|Expected life            |  | 6 years6.5 years        |  | 5 years6.25 years
|Expected dividends       |  | 0%                       |  | 0%                
|Expected volatility      |  | 55.13%58.63%            |  | 55.17%62.86%     

Expected Life.    The expected life is based on the
simplified method described in the SEC Staff Accounting Bulletin, Topic 14: Share-Based Payment.

Volatility.    Since the Company was a private entity for most of 2007 with no historical data regarding the volatility of its common stock, the expected volatility used for 2006 and 2007 is based on volatility of
similar entities, referred to as guideline companies. In evaluating similarity, the Company considered factors such as industry, stage of life cycle and size.

Risk-Free Interest Rate.    The risk-free rate is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options.

Dividend Yield.    The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the
foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model.

Forfeitures.    SFAS No. 123R also requires the Company to estimate forfeitures at the time of grant, and revise those estimates in subsequent periods if actual forfeitures differ from those estimates.
The Company uses historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis

over the requisite service periods of the awards, which are generally the vesting periods. If the Companys actual forfeiture rate is materially
different from its estimate, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period.

As of December 31, 2007 there was $3,582,339 of total unrecognized compensation costs related to non-vested stock option awards granted after January 1, 2006, which are expected to be recognized over a
weighted-average period of 3.60 years.

The aggregate intrinsic value of stock options (the amount by which the market price of the stock
on the date of exercise exceeded the exercise price of the option) exercised during the years ended December 31, 2007, 2006 and 2005, was $184,970, $13,198 and $0, respectively.

|(12) | Related Party Transactions
|---- | --------------------------

The Company shares
space with Restore Medical, Inc. (Restore), a related party who has directors and stockholders that are officers of the Company. The Company reimburses Restore for various facility expenses, including property taxes, common area maintenance charges,
payroll for the use of personnel, and shipping charges. Beginning in 2005 the Company also reimbursed Restore for rent expense related to the sublease agreement discussed in Note 13. Total expenses recorded were approximately $432,000, $256,000 and
$75,000 for the years ended December 31, 2007, 2006 and 2005, respectively, and approximately $831,000 for the period from December 19, 2002 (inception) to December 31, 2007. The majority of expenses are included in general and
administrative costs on the consolidated statements of operations. Included in accounts payable and accrued expenses are a total of $27,066 and $66,076 due to Restore as of December 31, 2007 and 2006, respectively.

and does not provide for the forfeiture of any vested or unvested options if after one year Mr. Griffin stops performing services as a consultant. The Company accounted for this transaction under the guidance of Emerging Issues Task Force
Abstract No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling Goods or Services.Under EITF 96-18, options are recorded at their fair value on the measurement

The Company is exposed to product liability claims that are inherent in the testing, production,
marketing and sale of medical devices. Management believes any losses that may occur from these matters are adequately covered by insurance, and the ultimate outcome of these matters will not have a material effect on the Companys financial
position or results of operations. The Company is not currently a party to any litigation and is not aware of any pending or threatened litigation that could have a material adverse effect on the Companys business, operating results or
financial condition.

In 2005, EnteroMedics entered into an exclusive collaborative obesity device research and development agreement with
the Mayo Foundation for Medical Education and Research (Mayo Foundation), Rochester, Minnesota. Through this agreement, EnteroMedics will collaborate with a group of physicians and researchers at Mayo Clinic in the field of obesity. Under the terms
of this five-year agreement, EnteroMedics and this group of Mayo specialists will collectively work toward the development of new and innovative medical devices for the treatment of obesity. The agreement also includes a similar collaboration for
the development of products to address a wide variety of disorders susceptible to treatment by electrically blocking neural impulses on the vagus nerve.

Under this agreement, the Company issued 219,780 shares of common stock to the Mayo Foundation in 2005 and recorded $100,000 as deferred compensation, which is being amortized over the term of the five-year agreement.
Unamortized deferred compensation related to the agreement was $41,667 and $61,667 at December 31, 2007 and 2006, respectively. In accordance with the agreement, upon the closing of the IPO in November 2007, the Company was also obligated to
issue 206,044 shares of common stock as consideration to the Mayo Foundation and recorded a one-time stock-based compensation expense of $1.7 million. The stock-based compensation expense is recorded on the consolidated statements of operations as
research and development expense.

The Company may also be obligated to pay the Mayo Foundation, contingent upon the occurrence of certain
future events, earned royalty payments, including a minimum annual royalty as defined by the agreement, for the commercial sale of products developed and patented by the Mayo Foundation, jointly patented by the Company

and the Mayo Foundation, or a product where the Mayo Foundation provided know-how as defined by the agreement. If no products are patented, the minimum
royalty is not due. The Mayo Foundation receives an annual $250,000 retainer fee which commenced in 2005 and continues through January 2009. The annual retainer fee paid to the Mayo Foundation is recorded on the consolidated statements of operations
as research and development expense.

In December 2007, EnteroMedics entered into a second research and development agreement with the Mayo
Foundation. In accordance with the three year agreement, the Mayo Foundation receives an annual $50,000 retainer fee. The annual retainer fee paid to the Mayo Foundation is recorded on the consolidated statements of operations as research and
development expense. The Company may also be obligated to pay the Mayo Foundation, contingent upon the occurrence of certain future events as defined by the agreement, consideration with respect to licensed know-how regarding product development and
testing of products and rights to licensed patents, where the Mayo Foundation provided know-how as defined by the agreement.

The Company has a 401(k)
profit-sharing plan that provides retirement benefits to employees. Eligible employees may contribute a percentage of their annual compensation, subject to Internal Revenue Service limitations. The Companys matching is at the discretion of the
