NOTES TO FINANCIAL STATEMENTS

(unaudited)

Note 1. Basis of Presentation

The accompanying unaudited interim financial statements of Opexa Therapeutics, Inc. (“Opexa”), a development stage company, have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules of the Securities and Exchange Commission and should be read in conjunction with the audited financial statements and notes thereto contained in Opexa’s latest Annual Report filed with the SEC on Form 10-K. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of financial position and the results of operations for the interim periods presented have been reflected herein. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Notes to the financial statements that would substantially duplicate the disclosure contained in the audited financial statements for the most recent fiscal year as reported in Form 10-K, have been omitted.

Note 2. Cash and Cash Equivalents

Opexa considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Investments with maturities in excess of three months but less than one year are classified as short-term investments and are stated at fair market value.

At March 31, 2011, Opexa invested approximately $11.3 million in a money market fund investing exclusively in high-quality, short-term money market instruments consisting of U.S. government obligations and repurchase agreements collateralized by the U.S. Government. While this fund seeks current income while preserving capital and liquidity, the fund is subject to risk, including U.S. government obligations risk. For the three months ended March 31, 2011, the money market fund recognized an average market yield of 0.01%. Interest income of $211 was recognized for the three months ended March 31, 2011 in the statements of expenses.

Note 3. Commitments and Contingencies

Stem Cell Technology Agreement

In 2009, Novartis Pharmaceuticals acquired Opexa’s stem cell technology platform, which had been in early preclinical development, and took over all future responsibilities and opportunities for this technology, although Opexa retains an option on certain manufacturing rights. As part of the transaction, Opexa was paid an upfront fee of $3 million and a milestone payment of $500,000 for certain technology transfer activities. Opexa remains eligible to receive a second technology transfer milestone fee in addition to potential clinical and commercial milestones and royalty payments from the sale of any products resulting from the use of the technology. However, there can be no assurance that Opexa will receive any future payments in respect of the stem cell technology.

Note 4. Loan Payable

Loan payable consists of an equipment credit line of $250,000 with Wells Fargo Bank of which $17,970 was outstanding as of March 31, 2011. This loan has an interest rate of 7.61% per annum, matures in May 2011 and is secured by furniture and equipment purchased with the loan proceeds. Payments are due and payable monthly until maturity.

Note 5. Equity

In January 2011, Opexa sold an aggregate of 384,759 shares of common stock under the Continuous Offering Program Agreement dated May 14, 2010 (the “ATM Agreement”) for net proceeds of $1,033,994. Under the ATM Agreement, prior to its termination as noted below, Opexa may sell an aggregate of up to 2,000,000 shares of common stock from time to time through the placement agent. The placement agent may sell the common stock by any method permitted by law, including sales deemed to be an “at the market” offering defined in Rule 415 of the Securities Act of 1933. Sales may be made directly on the NASDAQ Stock Market or to or through a market maker. The placement agent may also sell the common stock in privately negotiated transactions, subject to Opexa’s prior approval. Opexa will pay the placement agent a commission equal to 1% of the gross proceeds from the sale of common stock by it as agent under the ATM Agreement. The ATM Agreement may be terminated by either party at any time (without affecting any pending sale by the agent on behalf of Opexa). Opexa paid compensation and fees totaling $10,826 to the placement agent with respect to the shares sold. The ATM Agreement was subsequently terminated by Opexa on February 7, 2011.

- 4 -

In February 2011, Opexa sold an aggregate of 4,146,500 units in a public offering, with each unit consisting of one share of common stock and a warrant to purchase four-tenths (0.40) of a share of common stock, at a price to the public of $2.05 per unit, for gross proceeds of $8,500,325. The shares of common stock and warrants are immediately separable and were issued separately such that no units were issued. The warrants are exercisable immediately upon issuance, having a five-year term and an exercise price of $2.61 per share. The warrants have a fair value of $3,236,584 that was calculated using the Black-Scholes valuation model using the following assumptions: (1) discount rate of 2.38%, (2) term of 5 years, (3) expected volatility of 197.60% and (4) zero expected dividends. The net proceeds to Opexa from this offering were approximately $7,584,163, after deducting underwriting discounts and commissions and other offering expenses. The offering closed on February 11, 2011.

Note 6. Stock-Based Compensation

Restricted Shares

Pursuant to an agreement with a consultant for professional services, Opexa granted 50,305 restricted shares of common stock which were accounted for on March 19, 2011 pursuant to the relevant accounting rules. These shares vested immediately and were issued on April 8, 2011 and have a fair value of $87,028 based on the share price at the grant date, which was recognized as share-based compensation expense for the three months ended March 31, 2011.

Stock Options

The 2010 Stock Incentive Plan (the “2010 Plan”) provides for the grant of equity incentive awards to employees, directors and consultants of Opexa in the form of either incentive stock options or nonqualified stock options, as well as restricted stock, stock appreciation rights, restricted stock units and performance awards that may be settled in cash, stock or other property. The 2010 Plan is the successor to and continuation of Opexa’s June 2004 Compensatory Stock Option Plan (the “2004 Plan”). A total of 2,500,000 shares of common stock are authorized to be issued for awards made under the 2010 Plan through September 2020, plus the number of shares subject to stock options outstanding under the 2004 Plan that are forfeited or terminate prior to exercise and would otherwise be returned to the share reserves under the 2004 Plan and any reserved shares not issued or subject to outstanding grants. In addition, shares subject to awards granted under the 2010 Plan that terminate or expire before being exercised or settled will become available for grant under the plan. As of March 31, 2011, options to purchase an aggregate of 1,717,072 shares were issued and outstanding.

Opexa accounts for share-based compensation, including options and nonvested shares, according to the provisions of FASB ASC 718, "Share Based Payment.” During the three months ended March 31, 2011, Opexa recognized share-based compensation expense of $95,470. Unamortized stock compensation expense as of March 31, 2011 amounted to $587,408.

Business Overview

Unless otherwise indicated, we use “Opexa,” “the Company,” “we,” “our” and “us” in this quarterly report to refer to the businesses of Opexa Therapeutics, Inc.

We are a biopharmaceutical company developing personalized cellular therapies with the potential to treat major illnesses, including multiple sclerosis (MS). These therapies are based on our proprietary T-cell technology. The information discussed related to our product candidates is preliminary and investigative. Our product candidates are not approved by the Food and Drug Administration (FDA).

Our lead product candidate, Tovaxin®, is a personalized T-cell therapeutic vaccine licensed from Baylor College of Medicine, which is in late-stage clinical development for the treatment of MS.

T-Cell Therapy

Tovaxin® is a novel T-cell immunotherapy positioned to enter Phase III clinical development for the treatment of relapsing remitting MS (RR-MS). It is a personalized therapy that is specifically tailored to each patient’s disease profile. Tovaxin is manufactured using our proprietary method for the production of a patient-specific T-cell immunotherapy, which encompasses the collection of blood from the MS patient, isolation of peripheral blood mononuclear cells, generation of an autologous pool of myelin-reactive T-cells (MRTCs) raised against selected peptides from myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG) and proteolipid protein (PLP), and the return of these expanded, irradiated T-cells back to the patient. These attenuated T-cells are reintroduced into the patient via subcutaneous injection to trigger a therapeutic immune system response.

Summary of TERMS Phase IIb Clinical Trial Data

Tovaxin for Early Relapsing Multiple Sclerosis (TERMS) was a Phase IIb clinical study of Tovaxin in RR-MS patients. Although the study did not show statistical significance in its primary endpoint (the cumulative number of gadolinium-enhanced brain lesions using MRI scans summed at various points in the study), the study showed compelling evidence of efficacy in various clinical and other MRI endpoints.

The TERMS study was a multi-center, randomized, double blind, placebo-controlled trial in 150 patients with RR-MS or high risk Clinically Isolated Syndrome. Patients received a total of five subcutaneous injections at weeks 0, 4, 8, 12 and 24. Key results from the TERMS trial include:

●	In the modified intent to treat patient population (n=142), the annualized relapse rate (ARR) for Tovaxin-treated patients was 0.214 as compared to 0.339 for placebo-treated patients, which represented a 37% decrease in ARR for Tovaxin as compared to placebo in the general population;

●

In a prospective group of patients with more active disease (ARR>1, n=50), Tovaxin demonstrated a 55% reduction in ARR as compared to placebo, and a 73% reduction in relapse rate was observed in Tovaxin patients in this population compared to placebo during the 24-week period following the administration of the full course of treatment; and

●

In a retrospective analysis in patients naïve to previous disease modifying treatment (i.e., patients who had not previously used any drugs other than steroids to treat their disease), the results showed that patients, when treated with Tovaxin, had a 64% reduction in ARR versus placebo (p=0.046, n=70).

Tovaxin has demonstrated a favorable side effect profile throughout the clinical development program. In four clinical trials to date, including the Phase IIb TERMS trial, there have been no serious adverse events associated with Tovaxin treatment. The most common side effect is mild to moderate irritation at the site of injection, which is typically resolved in 24 hours. We believe the favorable safety profile of Tovaxin is a key differentiator when compared to marketed or other developmental MS drugs.

T-Cell Therapy Regulatory and Development Status

During 2010, we continued to analyze the data from the 2008 TERMS Phase IIb study and we evaluated options for the further clinical development of Tovaxin. In late 2010, we completed face-to-face discussions with the FDA regarding our planned development program for Tovaxin. Based on positive feedback from the FDA, we believe that we are now positioned from a regulatory perspective to advance with a pivotal Phase III clinical study of Tovaxin in RR-MS, subject to securing the appropriate financing to conduct such a study. We are in the process of completing necessary preparations to be able to initiate such a study.

Our recent discussions with the FDA consisted of two separate meetings to review both the complete Tovaxin manufacturing process as well as the prospective clinical trial plan for Tovaxin. The first meeting focused on the improvements and modifications we have incorporated into Tovaxin’s manufacturing and CMC (chemistry, manufacturing and control) process in an effort to improve efficiency, reduce overall costs and implement commercial stage requirements. As part of this meeting, we presented data and details supporting an optimized manufacturing process, including a transition to fewer process steps, comparability plans and complete reagent profiles. The FDA agreed that the optimized Tovaxin manufacturing process would meet the requirements for a pivotal Phase III clinical trial, although additional supporting data is expected to be submitted to the FDA prior to initiating such a study.

The second meeting was an “end of Phase II” clinical meeting in which we presented our rationale and trial design for a Phase III pivotal study with Tovaxin in RR-MS patients. The FDA concurred in general with our proposed clinical trial protocol, including the patient population, end points, patient numbers and overall trial design. The FDA also offered several recommendations to further enhance such a Phase III trial.

We currently intend to use the net proceeds of approximately $7.6 million from our February 2011 public offering for general corporate purposes (including working capital and operational purposes) and to prepare for and proceed toward the initiation of a pivotal Phase III clinical study in the United States of Tovaxin in RR-MS, although the proceeds from such offering together with our existing resources are not adequate to permit us to proceed materially beyond the initiation of such a study (i.e., the dosing of the first patient) or to complete such study or any significant portion of it. A pivotal Phase III clinical study in the United States of Tovaxin in RR-MS is expected to involve 240 patients and take approximately two and one-half years to complete. If we are able to commence such a study in the second half of 2011, the costs of such study as well as the ongoing expenses of our operations through the expected completion date of such study are estimated at approximately $35 million. Unless we secure at least a substantial portion of the additional resources that will be necessary to complete the planned Phase III study and support our operations during the pendency of such study, or we are reasonably confident that such resources will be secured, we would likely not proceed with the initiation of such study.

Given our need for substantial amounts of capital to undertake a pivotal Phase III clinical study in the United States of Tovaxin in RR-MS, we intend to continue to explore potential opportunities and alternatives to obtain the significant additional resources that will be necessary to complete the planned Phase III study and to support our operations during the pendency of such study. In addition to one or more additional financings, these opportunities and alternatives may include a partnering arrangement with a large biotech or pharmaceutical company. There can be no assurance that any such financings or partnering arrangement can be consummated on acceptable terms, if at all.

Assuming we are able to achieve financing which is sufficient to support the planned Phase III study in the United States and to support our operations during the pendency of such study, we are also preparing for a second pivotal Phase III clinical study in Europe. Any such second study would also depend upon the availability of sufficient resources.

Other Opportunities

Our proprietary T-cell technology has enabled us to develop intellectual property and a comprehensive sample database that may enable discovery of novel biomarkers and other relevant peptides to be used to treat MS patients.

Stem Cell Therapy

In 2009, Novartis Pharmaceuticals acquired our stem cell technology platform, which had been in early preclinical development, and took over all future responsibilities and opportunities for this technology, although we retain an option on certain manufacturing rights. As part of the transaction, we were paid an upfront fee of $3 million and a milestone payment of $500,000 for certain technology transfer activities. We remain eligible to receive a second technology transfer milestone fee in addition to potential clinical and commercial milestones and royalty payments from the sale of any products resulting from the use of the technology. However, there can be no assurance that we will receive any future payments in respect of the stem cell technology.

Critical Accounting Policies

General. Our discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect our most significant judgments and estimates used in preparation of our financial statements.

Stock-Based Compensation. We adopted the provisions of FASB ASC 718 which establishes accounting for equity instruments exchanged for employee service. We utilize the Black-Scholes option pricing model to estimate the fair value of employee stock based compensation at the date of grant, which requires the input of highly subjective assumptions, including expected volatility and expected life. Changes in these inputs and assumptions can materially affect the measure of estimated fair value of our share-based compensation. These assumptions are subjective and generally require significant analysis and judgment to develop. When estimating fair value, some of the assumptions will be based on, or determined from, external data and other assumptions may be derived from our historical experience with stock-based payment arrangements. The appropriate weight to place on historical experience is a matter of judgment, based on relevant facts and circumstances.

We estimated volatility by considering historical stock volatility. We have opted to use the simplified method for estimating expected term of options as equal to the midpoint between the vesting period and the contractual term.

Research and Development. The costs of materials and equipment or facilities that are acquired or constructed for research and development activities and that have alternative future uses are capitalized as tangible assets when acquired or constructed. The cost of such materials consumed in research and development activities and the depreciation of such equipment or facilities used in those activities are research and development costs. However, the costs of materials, equipment, or facilities acquired or constructed for research and development activities that have no alternative future uses are considered research and development costs and are expensed at the time the costs are incurred.

Results of Operations and Financial Condition

Comparison of the Three Months Ended March 31, 2011 with the Three Months Ended March 31, 2010

Net Sales. We recorded no commercial revenues for the three months ended March 31, 2011 and 2010.

Research and Development Expenses. Research and development expenses were $685,161 for the three months ended March 31, 2011, compared with $783,534 for the three months ended March 31, 2010. The decrease in expenses was primarily related to a decrease in the engagement of consultants, a decrease in the procurement and use of supplies in our laboratory, a reduction of stock compensation expense, and the reduction of expenses to recruit employees, and was partially offset by an increase of staff in preparation for increased development activities.

General and Administrative Expenses. General and administrative expenses for the three months ended March 31, 2011 were $592,058, compared with $484,425 for the three months ended March 31, 2010. The increase in expense is due to an increase in stock compensation expense to employees and an increase in business development activities, and was partially offset by a decrease in legal expense costs.

Interest Expense. Interest expense was $1,135 for the three months ended March 31, 2011, compared to $105,075 for the three months ended March 31, 2010. The decrease in interest expense was primarily related to the amortized interest on the April and May 2009 convertible notes incurred in the first quarter of 2010 (these notes were converted to common stock in June 2010). Interest expense for the three months ended March 31, 2011 related solely to the financing costs on insurance policies and the loan payable on the equipment line.

Interest Income. Interest income was $211 for the three months ended March 31, 2011, compared to $185 for the three months ended March 31, 2010.

Net loss. We had a net loss for the three months ended March 31, 2011 of approximately $1.31 million, or $0.06 per share (basic and diluted), compared with a net loss of approximately $1.42 million or $0.09 per share (basic and diluted) for the three months ended March 31, 2010. The decrease in net loss is primarily due to a decrease in professional fees and a decrease in the procurement and use of supplies in our laboratory, and was partially offset by an increase in stock compensation expense, an increase in business development activities, and an increase of staff in preparation for increased development activities.

Liquidity and Capital Resources

Historically, we have financed our operations primarily from the sale of debt and equity securities. As of March 31, 2011, we had cash and cash equivalents of approximately $11.4 million. Our financing activities generated $8.6 million for the three months ended March 31, 2011, compared to $40,614 for the same period of 2010. The cash generated in the first quarter of 2011 was proceeds from the sale of our securities in two separate offerings. During January 2011, we sold an aggregate of 384,759 shares of our common stock for net proceeds of $1,033,994 under an “at the market” continuous offering program pursuant to a prospectus supplement dated May 17, 2010. During February 2011, we raised net proceeds of approximately $7,584,163 through a public offering of common stock and warrants pursuant to a prospectus supplement dated February 8, 2011.

Our current burn rate, which is in the absence of any clinical trial but includes some preparation for initiation of a trial, is approximately $425,000 per month. While we believe we have sufficient liquidity to support our operations through 2011, we will need to raise additional capital in the future to fund our current business plan and support our operations.

We currently intend to use the proceeds from the February 2011 public offering for general corporate purposes (including working capital and operational purposes) and to prepare for and proceed toward the initiation of a pivotal Phase III clinical study in the United States of Tovaxin in RR-MS, although the proceeds from such offering together with our existing resources would not be adequate to permit us to proceed materially beyond the initiation of such a study (i.e., the dosing of the first patient) or to complete such study or any significant portion of it. A pivotal Phase III clinical study in the United States of Tovaxin in RR-MS is expected to involve 240 patients and take approximately two and one-half years to complete. If we are able to commence such a study in the second half of 2011, the costs of such study as well as the ongoing expenses of our operations through the expected completion date of such study are estimated at approximately $35 million. Unless we secure at least a substantial portion of the additional resources that will be necessary to complete the planned Phase III study and support our operations during the pendency of such study, or we are reasonably confident that such resources will be secured, we would likely not proceed with the initiation of such study.

- 10 -

Given our need for substantial amounts of capital, in addition to the proceeds from the February 2011 offering, to undertake a pivotal Phase III clinical study in the United States of Tovaxin in RR-MS, we intend to continue to explore potential opportunities and alternatives to obtain the significant additional resources that will be necessary to complete the planned Phase III study and to support the operations of the Company during the pendency of such study. In addition to one or more additional financings, these opportunities and alternatives may include a partnering arrangement with a large biotech or pharmaceutical company. There can be no assurance that any such financings or partnering arrangement can be consummated on acceptable terms, if at all.

We do not maintain any external lines of credit, or have commitments for equity funds, and should we need any additional capital in the future, management will be reliant upon “best efforts” debt or equity financings. As our prospects for funding, if any, develop during the fiscal year, we will assess our business plan and make adjustments accordingly. Although we have successfully funded our operations to date by attracting additional investors in our equity and debt securities, there is no assurance that our capital raising efforts will be able to attract additional necessary capital for our operations in the future. If we are unable to obtain additional funding for operations in the future, we may not be able to continue operations as proposed, requiring us to modify our business plan, curtail various aspects of our operations or cease operations.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings.

We are not currently a party to any material legal proceedings.

Item 1A. Risk Factors.

Reference is made to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Forward-Looking Statements” in Part I, Item 2 of this report. This Item 1A should be read in conjunction with Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010 filed with the Securities and Exchange Commission, which is incorporated herein by reference. Although we believe that the expectations reflected in any forward-looking statements we make are reasonable, we caution you that these expectations or predictions may not prove to be correct or we may not achieve the financial or operations results or other benefits anticipated in the forward-looking statements. Forward-looking statements are subject to a number of risks and uncertainties, which could cause our actual results to vary materially from those suggested by the forward-looking statements, such as:

●	Our business is at an early stage of development. We are largely dependent on the success of our lead product candidate, Tovaxin, and we cannot be certain that Tovaxin will receive regulatory approval or be successfully commercialized.

●	We have a history of operating losses and do not expect to be profitable in the near future.

●

We will be required to raise significant additional capital, or secure a development partner, in the near-term, and our ability to obtain funding is uncertain. If sufficient capital is not available, we may not be able to continue our operations as proposed (including any clinical trial for Tovaxin), which may require us to modify our business plan, curtail various aspects of our operations, cease operations or seek relief under applicable bankruptcy laws.

●	We will depend on strategic collaborations with third parties to develop and commercialize product candidates, such as Tovaxin, and we may not have control over a number of key elements relating to the development and commercialization of any such product candidate.

●

We will need regulatory approvals for any product candidate, including Tovaxin, prior to introduction to the market, which will require successful testing in clinical trials. Clinical trials are subject to extensive regulatory requirements, and are very expensive, time-consuming and difficult to design and implement. Any product candidate, such as Tovaxin, may fail to achieve necessary safety and efficacy endpoints during clinical trials in which case we will be unable to generate revenue from the commercialization and sale of our products.

●	We will rely on third parties to conduct our clinical trials and perform data collection and analysis, which may result in costs and delays that may hamper our ability to successfully develop and commercialize any product candidate, including Tovaxin.

●	If we fail to identify and license or acquire other product candidates, we will not be able to expand our business over the long term.

●	We are dependent upon our management team and a small number of employees.

●	If we fail to meet our obligations under our license agreements, we may lose our rights to key technologies on which our business depends.

●	Our current research and manufacturing facility is not large enough to manufacture product candidates, such as Tovaxin, for clinical trials or, if such clinical trials are successful, commercial applications.

●	If any product we may eventually have is not accepted by the market or if users of any such product are unable to obtain adequate coverage of and reimbursement for such product from government and other third-party payors, our revenues and profitability will suffer.

●	Any product candidate that we develop, such as Tovaxin, if approved for sale, may not gain acceptance among physicians, patients and the medical community, thereby limiting our potential to generate revenues.

●	We have incurred, and expect to continue to incur, increased costs and risks as a result of being a public company.

- 12 -

●	Patents obtained by other persons may result in infringement claims against us that are costly to defend and which may limit our ability to use the disputed technologies and prevent us from pursuing research and development or commercialization of potential products, such as Tovaxin.

●	If we are unable to obtain patent protection and other proprietary rights, our operations will be significantly harmed.

●	Confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and other proprietary information and may not adequately protect our intellectual property, which could limit our ability to compete.

●	A dispute concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be time consuming and costly, and an unfavorable outcome could harm our business.

●	We are subject to stringent regulation of our product candidates, such as Tovaxin, which could delay development and commercialization.

●	We may need to change our business practices to comply with health care fraud and abuse regulations, and our failure to comply with such laws could adversely affect our business, financial condition and results of operations.

●	If our competitors develop and market products that are more effective than our product candidates, they may reduce or eliminate our commercial opportunities.

●	Rapid technological change could make our products obsolete.

●	Consumers may sue us for product liability, which could result in substantial liabilities that exceed our available resources and damage our reputation.

●	Health care reform measures could adversely affect our business.

●	There is currently a limited market for our securities, and any trading market that exists in our securities may be highly illiquid and may not reflect the underlying value of our net assets or business prospects.

●	Our stock may be delisted from NASDAQ, which could affect its market price and liquidity.

●	As our share price is volatile, holders may not be able to resell our shares at a profit or at all.

●	We may be or become the target of securities litigation, which is costly and time-consuming to defend.

●	Our “blank check” preferred stock could be issued to prevent a business combination not desired by management or our current majority stockholders.

●	Future sales of our common stock in the public market could lower our stock price.

●	We presently do not intend to pay cash dividends on our common stock.

●	Our stockholders may experience substantial dilution in the value of their investment if we issue additional shares of our capital stock.

●	We may issue debt and equity securities or securities convertible into equity securities, any of which may be senior to our common stock as to distributions and in liquidation, which could negatively affect the value of our common stock.

●	Our management has significant flexibility in using the net proceeds of the February 2011 public offering.

The risks described in this report and in our Annual Report on Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.
