FORWARD-LOOKING STATEMENTS

Cornerstone Bancshares, Inc. (“Cornerstone”) may from time to time make written or oral statements, including statements contained in this report (including, without limitation, certain statements in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 2), that constitute forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). The words “expect,” “anticipate,” “intend,” “consider,” “plan,” “believe,” “seek,” “should,” “estimate,” and similar expressions are intended to identify such forward-looking statements, but other statements may constitute forward-looking statements. These statements should be considered subject to various risks and uncertainties. Such forward-looking statements are made based upon management’s belief as well as assumptions made by, and information currently available to, management pursuant to “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Cornerstone’s actual results may differ materially from the results anticipated in forward-looking statements due to a variety of factors. Such factors include, without limitation, those specifically described in Item 1A of Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, as well as the following:  (i) the possibility that our asset quality would decline or if we experience greater loan losses than anticipated, (ii) increased levels of other real estate, primarily as a result of foreclosures, (iii) the impact of liquidity needs on our results of operations and financial condition, (iv) competition from financial institutions and other financial service providers, (v) economic conditions in the local markets where we operate, (vi) the impact of obtaining regulatory approval prior to the payment of dividends, (vii) the impact of our Series A Preferred Stock on net income available to holders of our Common Stock and earnings per common share, (viii) the impact of negative developments in the financial industry and U.S. and global capital and credit markets, (ix) there can be no assurance that recently enacted legislation will continue to stabilize the U.S. financial system, (x) the relatively greater credit risk of residential construction and land development loans in our loan portfolio, (xi) adverse impact on operations and financial condition due to changes in interest rates, (xii) our ability to obtain additional capital and, if obtained, the possible significant dilution to current shareholders, (xiii) the impact of recently enacted legislation on our business, (xiv) the impact of federal and state regulations on our operations and financial performance, (xv) whether a significant deferred tax asset we have can be fully realized, (xvi) our ability to retain the services of key personnel, (xvii) the impact of Tennessee’s anti-takeover statutes and certain charter provisions on potential acquisitions of the holding company, and (xviii) our ability to adapt to technological changes. Many of such factors are beyond Cornerstone’s ability to control or predict, and readers are cautioned not to put undue reliance on such forward-looking statements. Cornerstone does not intend to update or reissue any forward-looking statements contained in this report as a result of new information or other circumstances that may become known to Cornerstone.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Nature of Business -Cornerstone is a bank holding company whose primary business is performed by its wholly-owned subsidiary, Cornerstone Community Bank (the “Bank”). The Bank provides a full range of banking services to the Chattanooga, Tennessee market. The Bank has also established a loan production office (“LPO”) in Dalton, Georgia to further enhance the Bank’s lending markets.

Interim Financial Information (Unaudited)- The financial information in this report for March 31, 2013 and March 31, 2012 has not been audited. The information included herein should be read in conjunction with the annual consolidated financial statements and footnotes thereto included in the 2012 Annual Report to Shareholders which was furnished to each shareholder of Cornerstone in April of 2013. The consolidated financial statements presented herein conform to U.S. generally accepted accounting principles and to general industry practices. In the opinion of Cornerstone’s management, the accompanying interim financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial condition, the results of operations, and cash flows for the interim period. Results for interim periods are not necessarily indicative of the results to be expected for a full year.

Use of Estimates -The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for loan losses.

Consolidation -The accompanying consolidated financial statements include the accounts of Cornerstone and the Bank. Substantially all intercompany transactions, profits and balances have been eliminated.

Reclassification- Certain amounts in the prior consolidated financial statements have been reclassified to conform to the current period presentation. The reclassifications had no effect on net income or stockholders’ equity as previously reported.

Accounting Policies -During interim periods, Cornerstone follows the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2012 as filed with the Securities and Exchange Commission. Since December 31, 2012, there have been no significant changes in any accounting principles or practices, or in the method of applying any such principles or practices, except for the following:

In February 2013, the Financial Accounting Standards Board (FASB) issued updated guidance related to disclosure of reclassification amounts out of other comprehensive income. The standard requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The new requirements took effect for public companies in fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted this standard on January 1, 2013. The effect of adopting this standard increases our disclosure requirements surrounding reclassification items out of accumulated other comprehensive income.

Earnings per Common Share - Basic earnings per share (“EPS”) is computed by dividing income available to common shareholders (numerator) by the weighted average number of common shares outstanding during the period (denominator). Diluted EPS is computed by dividing income available to common shareholders (numerator) by the adjusted weighted average number of shares outstanding (denominator). The adjusted weighted average number of shares outstanding reflects the potential dilution occurring if securities or other contracts to issue common stock were exercised or converted into common stock resulting in the issuance of common stock that share in the earnings of the entity.

The following is a summary of the basic and diluted earnings per share for the three month periods ended March 31, 2013 and March 31, 2012.

Accounting Policies- Cornerstone, as required by FASB, applies the fair value recognition provisions of ASC 718, Compensation –Stock Compensation. For the three month period ended March 31, 2013, no compensation cost was charged to earnings related to the vested incentive stock options.

Officer and Employee Plans -Cornerstone has two stock option plans under which officers and employees can be granted incentive stock options or non-qualified stock options to purchase a total of up to 1,420,000 shares of Cornerstone’s common stock. The exercise price for incentive stock options must be not less than 100 percent of the fair market value of the common stock on the date of the grant. The exercise price of the non-qualified stock options may be equal to or more or less than the fair market value of the common stock on the date of the grant. The incentive stock options vest 30 percent on the second anniversary of the grant date, 60 percent on the third anniversary of the grant date and 100 percent on the fourth anniversary of the grant date, and the non-qualified stock options vest 50 percent on the first anniversary of the grant date and 100 percent on the second anniversary of the grant date. The options expire ten years from the grant date. At March 31, 2013, the total remaining compensation cost to be recognized on non-vested options is approximately $596,000. A summary of the status of these stock option plans is presented in the following table:

The weighted average grant date fair value of stock options granted during the three months ended March 31, 2013 was $1.17. This was determined using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Board of Directors Plan -Cornerstone has a stock option plan under which members of the Board of Directors, at the formation of the Bank, were granted options to purchase a total of up to 600,000 shares of the Bank's common stock. On October 15, 1997, the Bank stock options were converted to Cornerstone stock options. Only non-qualified stock options may be granted under the plan. The exercise price of each option equals the market price of Cornerstone’s stock on the date of grant and the maximum term is ten years. Vesting is 50 percent on the first anniversary of the grant date and 100 percent on the second anniversary of the grant date. At March 31, 2013, the total remaining compensation cost to be recognized on non-vested options is approximately $123,000. A summary of the status of this stock option plan is presented in the following table:

The weighted average grant date fair value of stock options granted during the three months ended March 31, 2013 was $1.17. This was determined using the Black-Scholes option-pricing model with the following weighted-average assumptions:

At March 31, 2013, securities with a fair value totaling approximately $ 53 million were pledged to secure public funds, securities sold under agreements to repurchase, as collateral for federal funds purchased from other financial institutions and serve as collateral for borrowings at the Federal Reserve Discount Window.

The amortized cost and estimated market value of securities at March 31, 2013, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The following tables present the gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities available for sale have been in a continuous unrealized loss position, as of March 31, 2013 and as of December 31, 2012:

Upon acquisition of a security, the Bank determines the appropriate impairment model that is applicable.  If the security is a beneficial interest in securitized financial assets, the Bank uses the beneficial interests in securitized financial assets impairment model.  If the security is not a beneficial interest in securitized financial assets, the Bank uses the debt and equity securities impairment model.  The Bank conducts periodic reviews to evaluate each security to determine whether an other-than-temporary impairment has occurred.  The Bank does not have any securities that have been classified as other-than-temporarily-impaired at March 31, 2013 or December 31, 2012.

At March 31, 2013 and December 31, 2012, the significant categories of temporarily impaired securities, and management’s evaluation of those securities are as follows:

Mortgage-backed securities: At March 31, 2013, seven investments in residential mortgage-backed securities had unrealized losses.  This impairment is believed to be caused by the current interest rate environment.  The contractual cash flows of those investments are guaranteed or issued by an agency of the U.S. Government.  Because the decline in market value is attributable to the current interest rate environment and not credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Bank does not deem those investments to be other-than-temporarily impaired at March 31, 2013.

At March 31, 2013 and December 31, 2012, loans are summarized as follows (in thousands):

Cornerstone follows the loan impairment accounting guidance in ASC Topic 310. A loan is considered impaired when, based on current information and events, it is probable that Cornerstone will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans and loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in interest rates, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collections.

The composition of loans by loan classification for impaired and performing loan status at March 31, 2013 and December 31, 2012, is summarized in the tables below (amounts in thousands):

Credit quality indicators:

Federal regulations require the Bank to review and classify its assets on a regular basis. To fulfill this requirement, the Bank systematically reviews its loan portfolio to ensure the Bank’s large loan relationships are being maintained within its loan policy guidelines, remain properly underwritten and are properly classified by loan grade. This review process is performed by the Bank's management, loan review, internal auditors, and state and federal regulators.

The Bank’s loan grading process is as follows:

CORNERSTONE BANCSHARES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

If a loan is classified as a problem asset, it will be assigned one of the following loan grades: substandard, substandard-impaired, doubtful, and loss. “Substandard assets” must have one or more defined weaknesses and are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. “Doubtful assets” have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss. An asset classified “loss” is considered uncollectible and of such little value that continuance as an asset of the institution is not warranted. The regulations also provide for a “special mention” category, described as assets which do not currently expose an institution to a sufficient degree of risk to warrant classification but do possess credit deficiencies or potential weaknesses deserving close attention. When the Bank classifies an asset as substandard, or doubtful, a specific allowance for loan losses may be established.

The following tables outline the amount of each loan classification and the amount categorized into each risk rating as of March 31, 2013 and December 31, 2012 (amounts in thousands):
