CORCEPT THERAPEUTICS INCORPORATED

Our Business

Since our inception in May 1998, we have been developing mifepristone, a potent glucocorticoid receptor II (GR-II) antagonist. On February 17, 2012, the United States Food and Drug Administration (FDA) approved Korlym (mifepristone) 300 mg Tablets in the United States as a once-daily oral medication for treatment of hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing’s syndrome who have type 2 diabetes mellitus or glucose intolerance and have failed surgery or are not candidates for surgery. We released Korlym for sale on April 10, 2012. We also have an on-going phase 3 study of mifepristone, the active ingredient in Korlym, for treatment of the psychotic features of psychotic depression. We have also discovered three series of novel selective GR-II antagonists.

Cushing’s Syndrome. Cushing’s syndrome is a disorder caused by prolonged exposure of the body’s tissues to high levels of the hormone cortisol. Sometimes called “hypercortisolism,” it is relatively uncommon and most often affects adults aged 20 to 50. An estimated 10 to 15 of every one million people are newly diagnosed with this syndrome each year, resulting in approximately 3,000 new patients each year and an estimated prevalence of 20,000 patients with Cushing’s syndrome in the United States.

As discussed above, the FDA approved our New Drug Application (NDA) for Korlym on February 17, 2012. This approval allows us to market Korlym in the United States. We are implementing our plans, including hiring a small number of Medical Science Liaisons (MSLs) and engaging third-party vendors, to launch Korlym in the United States.

We have Orphan Drug Designations for Korlym from the FDA for the approved indication and from the European Commission for the treatment of endogenous Cushing’s syndrome. Orphan Drug Designation in the United States is a special status granted by the FDA to encourage the development of treatments for diseases or conditions that affect fewer than 200,000 patients in the United States. Drugs that receive Orphan Drug Designation obtain seven years of marketing exclusivity for the approved indication from the date of drug approval, as well as tax credits for clinical trial costs, marketing application filing fee waivers and assistance from the FDA in the drug development process. Benefits of Orphan Drug Designation in the European Union are similar to those in the United States, but include ten years of marketing exclusivity for the approved indication in all 27 member states, free scientific advice during drug development, access to a centralized review process and a reduction or complete waiver of fees levied by the European Medicines Agency.

Psychotic Depression. We are also developing mifepristone, the active ingredient in Korlym, for the treatment of the psychotic features of psychotic depression under an exclusive patent license from Stanford University. The FDA has granted “fast track” status to evaluate the safety and efficacy of mifepristone for the treatment of the psychotic features of psychotic depression.

In March 2008, we began enrollment in Study 14, our ongoing phase 3 trial in psychotic depression. The protocol for this trial incorporates what we have learned from our three previously completed phase 3

trials. It attempts to address the established relationship between increased drug plasma levels and clinical response and attempts to decrease the random variability observed in the results of the psychometric instruments used to measure efficacy. In one of the previously completed phase 3 trials, Study 06, we prospectively tested and confirmed that patients whose plasma levels rose above a predetermined threshold statistically separated from both those patients whose plasma levels were below the threshold and those patients who received placebo; this threshold was established from data produced in earlier studies.

As expected, the group of patients who took 1200 milligrams (mg) of mifepristone in Study 06 developed higher drug plasma levels than did the groups of patients who received lower doses. Further, there was no discernable difference in the incidence of adverse events between patients who received placebo in Study 06 and those who received 300 mg, 600 mg or 1200 mg of mifepristone in that study. In August 2011, we published our analysis of these data in The Journal of Clinical Psychopharmacology. Based on this information, we are testing a mifepristone dose of 1200 mg once per day for seven days in Study 14.

In addition, we are utilizing a third party centralized rating service to independently evaluate the patients for entry into the study as well as to evaluate their level of response throughout their participation in the study. We believe the centralization of this process will improve the consistency of rating across clinical trial sites and reduce the background statistical noise that was observed in earlier studies and is endemic to psychopharmacologic studies. We believe that this change in dose, as well as the other modifications to the protocol, should allow us to demonstrate the efficacy of mifepristone in the treatment of the psychotic symptoms of psychotic depression. In mid-2009, to conserve financial resources, we reduced the number of clinical sites in this study to eight and extended the timeline for its completion.

Antipsychotic-induced Weight Gain Mitigation. In 2005, we announced the results of studies in rats that demonstrated that mifepristone both reversed the weight gain associated with the ongoing use of olanzapine and mitigated the weight gain associated with the initiation of treatment with olanzapine (the active ingredient in Zyprexa). The results from this study were published in the journal Brain Behavioral Research in early 2006. This study was paid for by Eli Lilly and Company (Eli Lilly).

During 2007, we announced positive results from our clinical proof-of-concept study in lean healthy male volunteers evaluating the ability of mifepristone to mitigate weight gain associated with the use of Zyprexa. The results showed a statistically significant reduction in weight gain in those subjects who took Zyprexa plus mifepristone compared to those who took Zyprexa plus placebo. Also, the addition of mifepristone to treatment with Zyprexa had a beneficial impact on secondary metabolic measures such as fasting insulin, triglycerides and abdominal fat, as indicated by waist circumference. Eli Lilly provided Zyprexa and financial support for this study, the results of which were published in the journal Advances in Therapy in 2009. In January 2009, we announced positive results from a similar proof-of-concept study evaluating the ability of mifepristone to mitigate weight gain associated with the use of Johnson & Johnson’s Risperdal^®. This study confirmed and extended the earlier results seen with mifepristone and Zyprexa, demonstrating a statistically significant reduction in weight gain and in the secondary metabolic endpoints of fasting insulin, triglycerides and abdominal fat, as indicated by waist circumference. The results from the study of mifepristone and Risperdal were presented at several scientific conferences, including the American Diabetes Association meeting in June 2009, and were published in the journal Obesity in 2010.

The combination of Zyprexa or Risperdal and mifepristone is not approved for any indication. The purpose of these studies was to explore the hypothesis that GR-II antagonists, such as mifepristone and our next generation of selective GR-II antagonists, would mitigate weight gain associated with antipsychotic medications. The group of medications known as second generation antipsychotic

medication, including Zyprexa, Risperdal, Clozaril^® and Seroquel^®, are widely used to treat schizophrenia and bipolar disorder. All medications in this group are associated with treatment-emergent weight gain of varying degrees and carry a warning in their labels relating to treatment-emergent hyperglycemia and diabetes mellitus.

Selective GR-II Receptor Antagonists. In 2003, we initiated a discovery research program to identify and patent selective GR-II antagonists with the intent of developing a pipeline of products for proprietary use. Three distinct series of GR-II antagonists were identified. These compounds, like our lead product candidate mifepristone, potently block the cortisol receptor (GR-II) but, unlike mifepristone, they do not appear to block the PR (progesterone), ER (estrogen), AR (androgen) or GR-I (mineralocorticoid) receptors. Both the United States Patent & Trademark Office (USPTO) and the European Patent Office (EPO) have issued to us composition of matter patents on all of the three series. A fourth composition of matter patent application is pending.

Several of our new compounds have demonstrated positive results in animal models for the prevention and reversal of anti-psychotic-induced weight gain. One of them, CORT 108297, is in phase 1b/2a clinical trials. We have identified other selective GR-II antagonists from our proprietary series that we believe may have utility as therapeutic agents in a variety of diseases. Our intent is to continue our discovery research program with the goal of identifying new selective GR-II antagonists and to manufacture and conduct pre-clinical development on one or more of these compounds and to submit Investigational New Drug (IND) applications with respect to the most promising of them, as we deem appropriate.

We are continuing research and pre-clinical efforts to identify additional selective GR-II antagonists for clinical study.

In addition to the proceeds of this offering, we may require additional capital to fund as we deem appropriate the development of our next generation of selective GR-II antagonists. Unless we can generate the necessary funds from product revenue, we expect to finance our future cash needs for such purposes through public or private equity offerings, debt financings, structured finance transactions, corporate collaboration or licensing fees, or some combination thereof. We may enter into such a financing at any time, provided it is on terms we deem favorable to the Company.

NASDAQ Capital Market symbol		CORT

The number of shares of our common stock to be outstanding after this offering is based on 88,661,768 shares outstanding as of June 29, 2012 and excludes as of such date:

•

10,700,400 shares of common stock issuable upon the exercise of outstanding stock options at a weighted-average exercise price of $2.90 per share;

•

9,026,299 shares of common stock issuable upon the exercise of outstanding warrants at a weighted-average exercise price of $3.38 per share; and

•

5,010,131 additional shares of common stock reserved for future issuance under our 2012 Incentive Award Plan.

Investing in our common stock involves a high degree of risk. Before deciding whether to invest in our common stock, you should consider carefully the risk factors described below and discussed under the section captioned “Risk Factors” contained in our annual report on Form 10-K for the year ended December 31, 2011, and in our quarterly report on Form 10-Q for the quarter ended March 31, 2012, which are incorporated by reference in this prospectus supplement and the accompanying prospectus in its entirety, and in any free writing prospectus that we have authorized for use in connection with this offering. If any of these risks actually occur, it may materially harm our business, financial condition, operating results or cash flow. As a result, the market price of our common stock could decline, and you could lose all or part of your investment. Additional risks and uncertainties that are not yet identified or that we think are immaterial may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

You will experience immediate and substantial dilution in the book value per share of the common stock you purchase.

The public offering price of our common stock being offered is substantially higher than the net tangible book value per share of our common stock outstanding prior to this offering. Therefore, if you purchase our common stock in this offering, you will incur an immediate substantial dilution of $3.63 in net tangible book value per share from the price you paid based on an assumed public offering price of $4.49 per share, which represents the last reported sale price of our common stock on the NASDAQ Capital Market on June 29, 2012. In addition, if outstanding options and warrants are exercised, you will experience further dilution. For a further description of the dilution that you will experience immediately after this offering, see the section titled “Dilution.”

We have broad discretion to determine how to use the funds raised in this offering, and we may use them in ways that may not enhance our operating results or the price of our common stock.

Our management will have broad discretion over the use of proceeds from this offering, and we could spend the proceeds from this offering in ways with which you may not agree or that do not yield a favorable return. We intend to use the net proceeds from this offering to fund research and development activities, including clinical trials, and working capital and for general corporate purposes. We may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to our own, although we have no current plans, commitments or agreements with respect to any such acquisitions or investments. However, we have not allocated the net proceeds from this offering for any specific purposes. If we do not invest or apply the proceeds of this offering in ways that improve our operating results, we may fail to achieve expected financial results, which could cause our stock price to decline.

We depend heavily on the success of Korlym, which we only recently began to sell. If we are unable to commercialize Korlym successfully, or experience significant delays in doing so, we may not generate revenues as quickly as or at levels that we or investors expect and our stock price will likely decline.

We anticipate that for the foreseeable future our ability to generate meaningful revenues and achieve profitability will be solely dependent on the successful commercialization of Korlym. We only began to sell Korlym in April 2012, and have limited experience with its commercialization. Many factors could harm our efforts to commercialize Korlym, including:

Even if we are able to commercialize Korlym successfully, we cannot predict the rate at which such commercialization will occur. As our current ability to generate revenue is wholly dependent upon the commercialization of Korlym, the rate of such commercialization will directly and materially impact our results of operations. There are inherent difficulties in predicting the volumes at which Korlym will be sold and the potential for slower than anticipated adoption and manufacturing, distribution or other delays are heightened by our relative inexperience commercializing Korlym or other products. Due to such uncertainty, we have not provided any revenue forecasts to investors. Research analysts who cover our business have, however, put forth a wide range of estimates, based entirely on their own investigation and analysis. The Company has not guided or commented on these estimates and you should not rely on them. Our announcement of financial results that fail to meet such estimates, or other expectations of investors, could cause our stock price to decline.

Based on our limited experience marketing Korlym, a single order can represent a significant percentage of our aggregate revenues for a given period. Accordingly, receipt or delay of a single large order in a given period could significantly impact our reported revenue.

This prospectus supplement, the accompanying prospectus, the documents incorporated by reference and any free writing prospectus that we have authorized for use in connection with this offering contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and should be read in conjunction with the “Risk Factors” section of this prospectus supplement. All statements contained in this prospectus supplement other than statements of historical fact are forward-looking statements. When used in this report or elsewhere by management from time to time, the words “believe,” “anticipate,” “intend,” “plan,” “estimate,” “expect,” “may,” “will,” “should,” “seeks” and similar expressions are forward-looking statements. Such forward-looking statements are based on current expectations, but the absence of these words does not necessarily mean that a statement is not forward-looking. Forward-looking statements may include, but are not limited to statements about:

Forward-looking statements are not guarantees of future performance and involve risks and uncertainties. Actual events or results may differ materially from those discussed in the forward-looking statements as a result of various factors. For a more detailed discussion of such forward-looking statements and the potential risks and uncertainties that may impact upon their accuracy, see the “Risk Factors” beginning on page S-6 of this prospectus supplement and discussed in the sections captioned “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011, and in our quarterly report on Form 10-Q for the quarter ended March 31, 2012, which are incorporated by reference into this prospectus supplement, as the same may be updated from time to time by our future filings under the Exchange Act. These forward-looking statements reflect our view only as of the date of this prospectus supplement. You should read this prospectus supplement, the accompanying prospectus and the documents that we reference in this prospectus supplement and have filed as exhibits to the registration statement, of which this prospectus supplement is a part, completely and with the understanding that our actual future results may be materially different from what we expect. Except as required by law, we undertake no obligations to update any forward-looking statements. Accordingly, you should also carefully consider the factors set forth in other reports or documents that we file from time to time with the SEC.

We estimate that the net proceeds from the sale of the 11,000,000 shares of common stock that we are offering will be approximately $46.1 million, or approximately $53.0 million if the underwriter exercises in full its option to purchase up to 1,650,000 additional shares of common stock, after deducting estimated offering expenses payable by us.

We currently intend to use the net proceeds from the sale of our common stock in this offering to fund research and development activities, including clinical trials, and working capital and for general corporate purposes. We may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to our own, although we currently have no plans, commitments or agreements with respect to any such acquisitions or investments.

The amounts and timing of these expenditures may vary significantly depending on numerous factors, such as the rate of market acceptance of our lead product, our ability to obtain acceptable prices or adequate coverage and reimbursement for Korlym from third-party payors, the progress of our research and development efforts, actions of regulatory authorities, technological advances and the competitive environment for our products. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, we will retain broad discretion over the use of these proceeds.

We intend to invest the net proceeds in money market funds and/or short-term investment-grade securities until we are ready to use them.

Our net tangible book value as of March 31, 2012 was approximately $39.3 million, or approximately $0.44 per share. Net tangible book value per share is equal to the amount of our total tangible assets, less total liabilities, divided by the aggregate number of shares of our common stock outstanding as of March 31, 2012. Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering. After giving effect to the sale of 11,000,000 shares of common stock in this offering at an assumed public offering price of $4.49 per share, which represents the last reported sale price of our common stock on the NASDAQ Capital Market on June 29, 2012, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of March 31, 2012 would have been approximately $85.4 million, or approximately $0.86 per share. This represents an immediate dilution of $3.63 per share to new investors purchasing shares of common stock in this offering. The following table illustrates this dilution:

If the underwriter exercises in full its option to purchase up to 1,650,000 additional shares of common stock at the assumed public offering price of $4.49 per share, the as adjusted net tangible book value after this offering would have been $0.91 per share, representing an increase in net tangible book value of $0.47 per share to existing stockholders and immediate dilution of $3.58 per share to investors purchasing our common stock in this offering at the assumed public offering price.

The foregoing discussion and table do not take into account further dilution to new investors that could occur upon the exercise of outstanding options or warrants having a per share exercise price less than the per share offering price to the public in this offering. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

The foregoing discussion and table are based on 88,556,768 shares of common stock issued and outstanding as of March 31, 2012 and exclude, as of March 31, 2012:

The foregoing discussion and table also exclude the following stock and option transactions that were entered into subsequent to March 31, 2012:

Our amended and restated certificate of incorporation authorizes the issuance of up to 280,000,000 shares of common stock, par value $0.001 per share. As of June 29, 2012, there were 88,661,768 shares of our common stock held of record by approximately 127 registered stockholders, options to purchase 10,700,400 shares of common stock and warrants to purchase 9,026,299 shares of common stock outstanding.

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds.

In the event of our liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors; provided, however, that except as otherwise required by law, holders of common stock are not entitled to vote on any amendment to the certificate of incorporation that relates solely to the terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon by law or pursuant to the certificate of incorporation. No holder of our common stock has cumulative voting rights. Accordingly, the holders of a majority of the shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose. All of our directors are elected annually.

Holders of common stock have no preemptive or conversion rights or other subscription rights, and there are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are, and the shares of common stock offered by us in this offering, when issued and paid for, will be fully paid and non-assessable. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock which we may designate in the future.

Our common stock is subject to certain limitations on ownership and transfer. See “Certain Provisions of Delaware Law and of the Company’s Certificate of Incorporation and Bylaws” in the accompanying prospectus.

MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS

The following is a summary of the material U.S. federal income tax consequences applicable to non-U.S. holders (as defined below) with respect to the acquisition, ownership and disposition of shares of our common stock. This summary is based on current provisions of the Internal Revenue Code of 1986, as amended, or the Code, final, temporary or proposed Treasury regulations promulgated thereunder, administrative rulings and judicial opinions, all of which are subject to change, possibly with retroactive effect. We have not sought any ruling from the U.S. Internal Revenue Service, or the IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.

This summary is limited to non-U.S. holders who purchase our common stock issued pursuant to this offering and who hold shares of our common stock as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment).

This discussion does not address all aspects of U.S. federal income taxation that may be important to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances, nor does it address any aspects of U.S. federal estate or gift tax laws or tax considerations arising under the laws of any foreign, state or local jurisdiction. This discussion also does not address tax considerations applicable to a non-U.S. holder subject to special treatment under the U.S. federal income tax laws, including without limitation:

Accordingly, we urge prospective investors to consult with their own tax advisors regarding the U.S. federal, state, local and non-U.S. income and other tax considerations of acquiring, holding and disposing of shares of our common stock.

If a partnership (or other pass-through entity for U.S. federal income tax purposes) is a beneficial owner of our common stock, the tax treatment of a partner in the partnership (or member in such other entity) will generally depend upon the status of the partner and the activities of the partnership. Any partner in a partnership holding shares of our common stock should consult its own tax advisors.

PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

In general, a “non-U.S. holder” is any beneficial owner of our common stock that is not a U.S. person. A “U.S. person” is any of the following:

As described in our Annual Report on Form 10-K for the year ended December 31, 2011, which is incorporated by reference in this prospectus, we do not expect to pay cash dividends on our common stock in the foreseeable future. If, however, we make cash or other property distributions on our common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current earnings and profits for that taxable year or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and will first be applied against and reduce a holder’s adjusted tax basis in the common stock, but not below zero. Any excess will be treated as gain realized on the sale or other disposition of the common stock and will be treated as described under the section titled “—Gain on Sale or Other Disposition of Our Common Stock” below.

Dividends paid to a non-U.S. holder of our common stock generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends, or such lower rate specified by an applicable income tax treaty. To receive the benefit of a reduced treaty rate, a non-U.S. holder must furnish to us or our paying agent a valid IRS Form W-8BEN (or applicable successor form) certifying, under penalties of perjury, such holder’s qualification for the reduced rate. This certification must be provided to us or our paying agent prior to the payment of dividends and must be updated periodically. Non-U.S. holders that do not timely provide us or our paying agent with the required certification, but that qualify for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If a non-U.S. holder holds our common stock in connection with the conduct of a trade or business in the United States, and dividends paid on the common stock are effectively connected with such holder’s U.S. trade or business (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by the non-U.S. holder in the United States), the non-U.S. holder will be exempt from U.S. federal withholding tax. To claim the exemption, the non-U.S. holder must furnish to us or our paying agent a properly executed IRS Form W-8ECI (or applicable successor form).

Any dividends paid on our common stock that are effectively connected with a non-U.S. holder’s U.S. trade or business (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates in the same manner as if such holder were a resident of the United States. A non-U.S. holder that is a non-U.S. corporation also may be subject to an additional branch profits tax equal to 30% (or such lower rate specified by an applicable income tax treaty) of a portion of its effectively connected earnings and profits for the taxable year. Non-U.S. holders should consult any applicable income tax treaties that may provide for different rules.

A non-U.S. holder that claims the benefit of an applicable income tax treaty generally will be required to satisfy applicable certification and other requirements prior to the distribution date. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty.

Subject to the discussions below regarding backup withholding and foreign accounts, a non-U.S. holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:

We believe we currently are not, and we do not anticipate becoming, a USRPHC for U.S. federal income tax purposes.

Gain described in the first bullet point above will be subject to U.S. federal income tax on a net income basis at regular graduated U.S. federal income tax rates generally in the same manner as if such holder were a resident of the United States. A non-U.S. holder that is a non-U.S. corporation (or non-U.S. entity treated as a corporation for U.S. federal income tax purposes) also may be subject to an additional branch profits tax equal to 30% (or such lower rate specified by an applicable income tax treaty) of a portion of its effectively connected earnings and profits for the taxable year. Non-U.S. holders should consult any applicable income tax treaties that may provide for different rules.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a flat 30% rate (or such lower rate specified by an applicable income tax treaty) but may be offset by U.S. source capital losses (even though the individual is not considered a resident of the United States), provided that the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

Generally, we must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such holder (even if no withholding was required) and the amount of any tax withheld with respect to those dividends. This information also may be made available under a specific treaty or agreement with the tax authorities of the country in which the non-U.S. holder resides or is established. Under certain circumstances,

the Code imposes a backup withholding obligation (currently at a rate of 28%) on certain reportable payments. Backup withholding generally will not, however, apply to payments of dividends to a non-U.S. holder of our common stock provided the non-U.S. holder furnishes to us or our paying agent the required certification as to its non-U.S. status, such as by providing a valid IRS Form W-8BEN or W-8ECI, or otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale of our common stock within the United States or conducted through certain U.S.-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder on Form W-8BEN or other applicable form (and the payor does not have actual knowledge or reason to know that the beneficial owner is a U.S. person) or such owner otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Withholding taxes on certain types of payments made to “foreign financial institutions” (as specially defined under those rules) and certain other non-U.S. entities. Under this legislation, the failure to comply with additional certification, information reporting and other specified requirements could result in withholding tax being imposed on payments of dividends and sales proceeds to foreign intermediaries and certain non-U.S. holders. The legislation may impose a 30% withholding tax on dividends on, or gross proceeds from the sale or other disposition of, our common stock paid to a foreign financial institution or to a non-financial foreign entity, unless (i) the foreign financial institution undertakes certain diligence and reporting obligations, (ii) the non-financial foreign entity either certifies it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner, or (iii) the foreign financial institution of non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (i) above, it must enter into an agreement with the U.S. Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts and withhold 30% on payments to non-compliant foreign financial institutions and certain other account holders.

Although the withholding rules described above currently apply to applicable payments made after December 31, 2012, the IRS has recently issued proposed Treasury regulations providing that the withholding provisions described above will generally apply to payments of dividends on our common stock made on or after January 1, 2014 and to payments of gross proceeds from a sale or other disposition of our common stock on or after January 1, 2015. Prospective investors should consult their tax advisors regarding these withholding provisions.

Under the terms and subject to the conditions contained in an underwriting agreement dated the date of this prospectus supplement, we will sell to Credit Suisse Securities (USA) LLC, the underwriter, all of the shares of common stock offered hereby.

The underwriter is purchasing the shares of common stock from us at $4.22 per share (representing $46.4 million aggregate proceeds to us, before we deduct our estimated offering expenses of approximately $350,000). The underwriting agreement provides that the underwriter is obligated to purchase all shares of common stock if any are purchased.

We have granted to the underwriter a 30-day option to purchase up to 1,650,000 additional shares at a price of $4.22 per share.

The underwriter will offer the shares of common stock for sale from time to time in one or more transactions (which may include block transactions), in negotiated transactions or otherwise, or a combination of those methods of sale, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The underwriter may do so by selling the shares of common stock to or through broker/dealers, who may receive compensation in the form of underwriting discounts, concessions or commissions from the underwriter and/or the purchasers of the shares of common stock for whom they may act as agents. In connection with the sale of the shares of common stock, the underwriter may be deemed to have received compensation from us in the form of underwriting discounts, and the underwriter may also receive commissions from the purchasers of the shares of common stock for whom it may act as agent. The underwriter and any broker/dealers that participate with the underwriter in the distribution of the shares of common stock may be deemed to be underwriters, and any discounts or commissions received by them and any profit on the resale of the shares of common stock by them may be deemed to be underwriting discounts or commissions.

We have agreed to indemnify the underwriter against liabilities under the Securities Act of 1933, or contribute to payments that the underwriter may be required to make in that respect.

We have agreed that we will not offer, sell, issue, contract to sell, pledge or otherwise dispose of, directly or indirectly, enter into any swap, hedge or any other agreement that transfers, in whole or in part, the economic consequences of ownership of, establish or increase a put equivalent position or liquidate or decrease a call equivalent position in, or file with the Securities and Exchange Commission a registration statement under the Securities Act (other than a registration statement on Form S-8 related to employee stock options or other equity rights pursuant to the terms of a plan in effect on the date hereof) relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the underwriter for a period of 90 days after the date of this prospectus, except grants of employee stock options or other equity rights pursuant to the terms of a plan in effect on the date hereof, issuances of shares of our common stock pursuant to the exercise of such options, the vesting of such equity rights or the exercise of any other employee stock options or warrants outstanding on the date hereof.

Our directors and executive officers and certain significant stockholders, including Longitude Venture Partners, L.P. and Sutter Hill Ventures, have agreed, subject to certain limited exceptions (including an exception for any transaction consummated in accordance with a valid contract, instruction or plan that satisfies the requirements of Rule 10b5-1 under the Exchange Act), that they will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of common stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock, whether any such aforementioned transaction is to be settled by delivery of our common stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Credit Suisse Securities (USA) LLC for a period of 90 days after the date of this prospectus supplement.

The shares of common stock have been approved for listing on the NASDAQ Capital Market, under the symbol “CORT”.

In connection with the offering the underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions, penalty bids, and passive market making in accordance with Regulation M under the Exchange Act.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the NASDAQ Capital Market or otherwise and, if commenced, may be discontinued at any time.

A prospectus in electronic format may be made available on the web sites maintained by the underwriter, or selling group members, if any, participating in this offering and the underwriter may distribute prospectuses electronically.

The underwriter may, from time to time, engage in transactions with and perform services for us or our affiliates in the ordinary course of its respective businesses.

The distribution of the shares of common stock in Canada is being made only in the provinces of Ontario, Quebec, Alberta, British Columbia and Manitoba on a private placement basis exempt from the requirement that we prepare and file a prospectus with the securities regulatory authorities in each province where trades of the shares of common stock are made. Any resale of the shares of common stock in Canada must be made under applicable securities laws which may vary depending on the relevant jurisdiction, and which may require resales to be made under available statutory exemptions or under a discretionary exemption granted by the applicable Canadian securities regulatory authority. Purchasers are advised to seek legal advice prior to any resale of the shares of common stock.

By purchasing the shares of common stock in Canada and accepting delivery of a purchase confirmation, a purchaser is representing to us and the dealer from whom the purchase confirmation is received that:

Under Ontario securities legislation, certain purchasers who purchase a security offered by this prospectus supplement during the period of distribution will have a statutory right of action for damages, or while still the owner of the shares of common stock, for rescission against us in the event that this prospectus supplement contains a misrepresentation without regard to whether the purchaser relied on the misrepresentation. The right of action for damages is exercisable not later than the earlier of 180 days from the date the purchaser first had knowledge of the facts giving rise to the cause of action and three years from the date on which payment is made for the shares of common stock. The right of action for rescission is exercisable not later than 180 days from the date on which payment is made for the shares of common stock. If a purchaser elects to exercise the right of action for rescission, the purchaser will have no right of action for damages against us. In no case will the amount recoverable in any action exceed the price at which the shares of common stock were offered to the purchaser and if the purchaser is shown to have purchased the securities with knowledge of the misrepresentation, we will have no liability. In the case of an action for damages, we will not be liable for all or any portion of the damages that are proven to not represent the depreciation in value of the shares of common stock as a result of the misrepresentation relied upon. These rights are in addition to, and without derogation from, any other rights or remedies available at law to an Ontario purchaser. The foregoing is a summary of the rights available to an Ontario purchaser. Ontario purchasers should refer to the complete text of the relevant statutory provisions.

All of our directors and officers as well as the experts named herein may be located outside of Canada and, as a result, it may not be possible for Canadian purchasers to effect service of process within Canada upon us or those persons. All or a substantial portion of our assets and the assets of those persons may be located outside of Canada and, as a result, it may not be possible to satisfy a judgment against us or those persons in Canada or to enforce a judgment obtained in Canadian courts against us or those persons outside of Canada.

Canadian purchasers of the shares of common stock should consult their own legal and tax advisors with respect to the tax consequences of an investment in the shares of common stock in their particular circumstances and about the eligibility of the shares of common stock for investment by the purchaser under relevant Canadian legislation.

We are a pharmaceutical company engaged in the discovery, development and commercialization of drugs for the treatment of severe metabolic and psychiatric disorders. Our focus is on those disorders that are associated with a steroid hormone called cortisol. Elevated levels and abnormal release patterns of cortisol have been implicated in a broad range of human disorders. Since our inception in May 1998, we have been developing our lead product, CORLUX^®, a potent glucocorticoid receptor II (GR-II) antagonist, that blocks the activity of cortisol. We have also discovered three series of novel selective GR-II antagonists and have moved CORT 108297, a compound from one of these series, into clinical development. Unless otherwise stated, all references in this prospectus to “we,” “us,” “our,” “Corcept,” the “Company,” “our company” and similar designations refer to Corcept Therapeutics Incorporated.

The Investigational New Drug application (IND) for the evaluation of CORLUX for the treatment of the signs and symptoms of Cushing’s Syndrome was opened in September 2007. The United States Food and Drug Administration (FDA) indicated that our single 50-patient open-label study may provide a reasonable basis for the submission of a New Drug Application (NDA) for this indication. We completed enrollment in this Phase 3 study in June 2010. This open-label Phase 3 study evaluated the response of two patient groups to CORLUX treatment: one included patients who were glucose intolerant, regardless of blood pressure level, and one included patients who had been diagnosed with hypertension but had normal glucose tolerance. The patients in both of these groups were being treated for their symptoms before study entry; CORLUX was added to their existing medications. In December 2010 we announced that both groups in this study achieved their primary endpoints. In January 2011 we announced positive results for the key secondary endpoint of global clinical improvement. All of the patients in the study were included in one group for this endpoint.

Statistically significant improvement in the primary endpoint was achieved for each group with 60% responding in the group of patients with abnormal glucose tolerance with or without a diagnosis of hypertension (the “glucose intolerant group”) and 38% responding in the group of patients with a diagnosis of hypertension (the “hypertensive group”.) The patients in the study, whether included in the “glucose intolerant group” or the “hypertensive group” for the purpose of evaluating the primary endpoints, were evaluated as a single group on the key secondary endpoint of “global clinical improvement”; 87% of patients showed significant clinical improvement as evaluated by an independent board of three physicians highly experienced in the treatment of Cushing’s Syndrome. A review of the safety data indicates that CORLUX had an acceptable risk-benefit profile in this Phase 3 study. Adverse events related to treatment included signs and symptoms of adrenal insufficiency, endometrial thickening, and hypokalemia, all of which were consistent with earlier published reports. The majority of the serious adverse events (SAEs) reported in the study were not related to CORLUX treatment, as determined by the clinical investigators. All of the treatment-related SAEs resolved with clinical management. Eighty-eight percent of the patients who completed the Phase 3 study opted to enter the long-term extension study. We submitted our NDA for the use of CORLUX in Cushing’s Syndrome on April 15, 2011. Our submission included a proposal for our Risk Evaluation and Mitigation Strategies (REMS) and a request for Priority Review, for which the FDA’s goal for completion is six months. We plan to present detailed data from the Phase 3 trial at scientific conferences during 2011. We are developing plans and engaging third-party vendors to support a commercial launch of CORLUX in the United States, if it is approved by the FDA.

In July 2007, we received Orphan Drug Designation from the FDA for CORLUX for the treatment of endogenous Cushing’s Syndrome. Orphan Drug Designation is a special status granted by the FDA to encourage the development of treatments for diseases or conditions that affect fewer than 200,000 patients in the United States. Drugs that receive Orphan Drug Designation obtain seven years of marketing exclusivity from the date of drug approval, as well as tax credits for clinical trial costs, marketing application filing fee waivers and assistance from the FDA in the drug development process.

In March 2008, we began enrollment in Study 14, our ongoing Phase 3 trial in psychotic depression. The protocol for this trial incorporates what we have learned from our three previously completed Phase 3 trials. It attempts to address the established relationship between increased drug plasma levels and clinical response and attempts to decrease the random variability observed in the results of the psychometric instruments used to measure efficacy. In one of the previously completed Phase 3 trials, Study 06, we prospectively tested and confirmed that patients whose plasma levels rose above a predetermined threshold statistically separated from both those patients whose plasma levels were below the threshold and those patients who received placebo; this threshold was established from data produced in earlier studies.

As expected, patients who took 1200 milligrams (mg) of CORLUX in Study 06 developed higher drug plasma levels than patients who received lower doses. Further, there was no discernable difference in the incidence of adverse events between patients who received placebo in Study 06 and those who received 300 mg, 600 mg or 1200 mg of CORLUX in that study. Based on this information, we are using a CORLUX dose of 1200 mg once per day for seven days in Study 14.

In addition, we also are utilizing a third party centralized rating service to independently evaluate the patients for entry into the study as well as to evaluate their level of response throughout their participation in the study. We believe the centralization of this process will improve the consistency of rating across clinical trial sites and reduce the background noise that was experienced in earlier studies and is endemic to psychopharmacologic studies. We believe that this change in dose, as well as the other modifications to the protocol, should allow us to demonstrate the efficacy of CORLUX in the treatment of the psychotic symptoms of psychotic depression. In mid-2009, in order to conserve financial resources, we reduced the number of clinical sites in this study to eight and extended the timeline for its completion.

During 2007 we announced positive results from our clinical proof-of-concept study in lean healthy male volunteers evaluating the ability of CORLUX to mitigate weight gain associated with the use of Zyprexa. The results show a statistically significant reduction in weight gain in those subjects who took Zyprexa plus CORLUX compared to those who took Zyprexa plus placebo. Also, the addition of CORLUX to treatment with Zyprexa had a beneficial impact on secondary metabolic measures such as fasting insulin, triglycerides and abdominal fat, as indicated by waist circumference. Eli Lilly provided Zyprexa and financial support for this study and its results were published in the journal Advances in Therapy in 2009. In January 2009, we announced positive results from a similar proof-of-concept study evaluating the ability of CORLUX to mitigate weight gain associated with the use of Johnson & Johnson’s Risperdal. This study confirmed and extended the earlier results seen with CORLUX and Zyprexa, demonstrating a statistically significant reduction in weight gain and in the secondary metabolic endpoints of fasting insulin, triglycerides and abdominal fat, as indicated by waist circumference. The results from the study of CORLUX and Risperdal were presented at several scientific conferences, including the American Diabetes Association meeting in June 2009, and were published in the journal Obesity in 2010.

The combination of Zyprexa or Risperdal and CORLUX is not approved for any indication. The purpose of these studies was to explore the hypothesis that GR-II antagonists, such as CORLUX and our next generation of selective GR-II antagonists, would mitigate weight gain associated with antipsychotic medications. The group of medications known as second generation antipsychotic medication, including Zyprexa, Risperdal, Clozaril and Seroquel, are widely used to treat schizophrenia and bipolar disorder. All medications in this group are

associated with treatment emergent weight gain of varying degrees and carry a warning in their labels relating to treatment emergent hyperglycemia and diabetes mellitus.

In 2007, we conducted a human microdosing study of one of our newly identified selective GR-II antagonists, CORT 108297, with Xceleron Limited utilizing its Accelerator Mass Spectrometry technology. In this microdosing study, we evaluated CORT 108297, a compound which develops particularly high plasma and brain concentrations in an animal model. In May 2008, we announced the results from this study, which demonstrated that CORT 108297 was extremely well absorbed, demonstrated good bioavailability and had a half-life that appears compatible with once-a-day oral dosing. In addition, further pharmacokinetic testing of CORT 108297 in a rat model indicated that a ten-fold increase in oral dose (5 milligrams per kilogram (mg/kg) to 50 mg/kg) led to a proportional increase in the amount of compound detected in plasma.

In September 2008, we signed a second agreement with Eli Lilly, under which Eli Lilly agreed to provide funding and provide olanzapine for two studies to test the effectiveness of CORT 108297 in rat models of olanzapine induced weight gain. In January 2009, we announced top-line results from these studies of CORT 108297 and olanzapine. The results from the studies of both the prevention and reversal of antipsychotic-induced weight gain were positive and statistically significant. The results of these studies were presented at the International Society of Psychoneuroendocrinology and the World Congress of Biological Psychiatry conferences in July 2009.

At the American Diabetes Association conference in June 2009 there was also a presentation of preclinical data from another study of CORT 108297 conducted at Stanford University. This study demonstrated that CORT 108297 suppresses body weight gain and improves insulin sensitivity in healthy mice fed a 60% fat diet and high sucrose liquid.

The manufacturing and preclinical development of CORT 108297 began late in 2008 and resulted in the submission of an IND to the FDA in December 2009 for the prevention of weight gain induced by antipsychotic medication. Dosing of healthy volunteers in the first Phase 1 study of CORT 108297 was completed in July 2010. A Phase 1b/2a study of this drug evaluating the compound in models of antipsychotic-induced weight gain and changes in biomarkers induced by prednisone, a commonly prescribed glucocorticosteroid associated with metabolic effects, was initiated during the fourth quarter of 2010, with the first patients being dosed in December 2010.

During the second quarter of 2010, we selected a second new compound, CORT 113083, to advance toward an IND filing. CORT 113083 has demonstrated substantial bioavailability in animal models. During the third quarter of 2010, we commenced various manufacturing development and preclinical studies supporting an IND filing for this compound.

Forward-looking statements are not guarantees of future performance and involve risks and uncertainties. Actual events or results may differ materially from those discussed in the forward-looking statements as a result of various factors. For a more detailed discussion of such forward-looking statements and the potential risks and uncertainties that may impact upon their accuracy, see the “Risk Factors” section of our most recent Annual Report on Form 10-K and of our subsequent Quarterly Reports on Form 10-Q (including any amendments thereto), which are incorporated by reference into this prospectus, as the same may be updated from time to time by our future filings under the Exchange Act. These forward-looking statements reflect our view only as of the date of this prospectus. You should read this prospectus and the documents that we reference in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect. Except as required by law, we undertake no obligations to update any forward-looking statements. Accordingly, you should also carefully consider the factors set forth in reports or documents that we file from time to time with the Securities and Exchange Commission.

Except at otherwise provided in the applicable prospectus supplement, we intend to use the net proceeds to fund research, development and commercialization activities, including clinical trials, to fund working capital and for general corporate purposes. We may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to our own, although we currently have no plans, commitments or agreements with respect to any such acquisitions or investments. The amounts and timing of the expenditures will depend on numerous factors, such as the timing and progress of our clinical trials and research and development efforts, technological advances and the competitive environment for our drug candidates. We intend to invest the net proceeds in money market funds and/or short-term investment-grade securities until we are ready to use them.

Our earnings are inadequate to cover fixed charges. The following table sets forth the dollar amount of the coverage deficiency (in thousands) for the periods indicated.

We have not included a ratio of earnings to combined fixed charges and preferred stock dividends because we do not have any preferred stock outstanding.

We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities (1) through underwriters or dealers, (2) through agents and/or (3) directly to one or more purchasers. We may distribute the securities from time to time in one or more transactions at:

We may solicit directly offers to purchase the securities being offered by this prospectus. We may also designate agents to solicit offers to purchase the securities from time to time. We will name in a prospectus supplement any agent involved in the offer or sale of our securities.

If we utilize a dealer in the sale of the securities being offered by this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale and we will provide the name of any underwriter in the prospectus supplement which the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions.

With respect to underwritten public offerings, negotiated transactions and block trades, we will provide in the applicable prospectus supplement any compensation we pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended, or the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof.

To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

The underwriters, dealers and agents may engage in other transactions with us, or perform other services for us, in the ordinary course of their business.

We, directly or through agents, dealers or underwriters designated from time to time, may offer, issue and sell, together or separately, up to $100,000,000 in the aggregate of:

We may issue the debt securities as exchangeable for or convertible into shares of common stock, preferred stock or other securities. The preferred stock may also be exchangeable for and/or convertible into shares of common stock, another series of preferred stock or other securities. The debt securities, the preferred stock, the common stock and the warrants are collectively referred to in this prospectus as the securities. When a particular series of securities is offered, a supplement to this prospectus will be delivered with this prospectus, which will set forth the terms of the offering and sale of the offered securities.

This prospectus describes certain general terms and provisions of the debt securities we may offer pursuant to this prospectus. When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a supplement to this prospectus. The following description of debt securities will apply to the debt securities offered by this prospectus unless we provide otherwise in the applicable prospectus supplement and in a supplement to the indenture, a board resolution or an officers’ certificate delivered pursuant to the indenture. The applicable prospectus supplement for a particular series of debt securities may specify different or additional terms.

We may offer under this prospectus secured or unsecured debt securities. The debt securities may be either senior debt securities, senior subordinated debt securities or subordinated debt securities.

The debt securities offered by this prospectus will be issued under an indenture between us and a trustee. We have filed a copy of the form of indenture as an exhibit to the registration statement and you should read the indenture for provisions that may be important to you. We have summarized select portions of the indenture below. The summary is not complete. In the summary below, we have included references to the section numbers of the indenture so that you can easily locate these provisions. Capitalized terms used in the summary below have the meanings specified in the indenture.

The terms of each series of debt securities will be established by or pursuant to a resolution of our board of directors and detailed or determined in the manner provided in a board of directors resolution, an officers’ certificate or by a supplemental indenture. (Section 2.2) The particular terms of each series of debt securities will be described in a prospectus supplement relating to the series, including any pricing supplement.

We can issue an unlimited amount of debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will set forth in a prospectus supplement (including any pricing supplement) relating to any series of debt securities being offered, the initial offering price, the aggregate principal amount and the following terms of the debt securities:

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and any premium and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company, as Depositary, or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a book-entry debt security), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a certificated debt security), as described in the applicable prospectus supplement. Except as described under “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. You may transfer or exchange certificated debt securities at the trustee’s office or paying agencies in accordance with the terms of the indenture. No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

You may transfer certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the old certificate representing those certificated debt securities and either we or the trustee will reissue the old certificate to the new holder or we or the trustee will issue a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary.

The Depositary has indicated it intends to follow the following procedures with respect to book-entry debt securities.

Ownership of beneficial interests in book-entry debt securities will be limited to persons that have accounts with the Depositary for the related global debt security (we shall refer to these persons as participants) or persons that may hold interests through participants. Upon the issuance of a global debt security, the Depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the book-entry debt securities represented by the global debt security beneficially owned by such participants. The accounts to be credited will be designated by any dealers, underwriters or agents participating in the distribution of the book-entry debt securities. Ownership of book-entry debt securities will be shown on, and the transfer of the ownership interests will be effected only through, records maintained by the Depositary for the related global debt security (with respect to interests of participants) and on the records of participants (with respect to interests of persons holding through participants). The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to own, transfer or pledge beneficial interests in book-entry debt securities.

So long as the Depositary for a global debt security, or its nominee, is the registered owner of that global debt security, the Depositary or its nominee, as the case may be, will be considered the sole owner or holder of the book-entry debt securities represented by such global debt security for all purposes under the indenture. Except as described in this prospectus, beneficial owners of book-entry debt securities will not be entitled to have securities registered in their names, will not receive or be entitled to receive physical delivery of a certificate in definitive form representing securities and will not be considered the owners or holders of those securities under the indenture. Accordingly, to exercise any rights of a holder under the indenture, each person beneficially owning book-entry debt securities must rely on the procedures of the Depositary for the related global debt security and, if that person is not a participant, on the procedures of the participant through which that person owns its interest.

We understand, however, that under existing industry practice, the Depositary will authorize the persons on whose behalf it holds a global debt security to exercise certain rights of holders of debt securities, and the indenture provides that we, the trustee and our respective agents will treat as the holder of a debt security the persons specified in a written statement of the Depositary with respect to that global debt security for purposes of obtaining any consents or directions required to be given by holders of the debt securities pursuant to the indenture. (Section 2.14.6)

We will make payments of principal of, and premium and interest on book-entry debt securities to the Depositary or its nominee, as the case may be, as the registered holder of the related global debt security. (Section 2.14.5) We, the trustee and any other agent of ours or agent of the trustee will not have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that the Depositary, upon receipt of any payment of principal of, premium or interest on a global debt security, will immediately credit participants’ accounts with payments in amounts proportionate to the respective amounts of book-entry debt securities held by each participant as shown on the records of the Depositary. We also expect that payments by participants to owners of beneficial interests in book-entry debt securities held through those participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

We will issue certificated debt securities in exchange for each global debt security if the Depositary is at any time unwilling or unable to continue as Depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor Depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days. In addition, we may at any time and in our sole discretion determine not to have any of the book-entry debt securities of any series represented by one or more global debt securities and, in that event, we will issue certificated debt securities in exchange for the global debt securities of that series. Global debt securities will also be exchangeable by the holders for certificated debt securities if an event of default with respect to the book-entry debt securities represented by those global debt securities has occurred and is continuing. Any certificated debt securities issued in exchange for a global debt security will be registered in such name or names as the Depositary shall instruct the trustee. We expect that such instructions will be based upon directions received by the Depositary from participants with respect to ownership of book-entry debt securities relating to such global debt security.

We have obtained the foregoing information in this section concerning the Depositary and the Depositary’s book-entry system from sources we believe to be reliable, but we take no responsibility for the accuracy of this information.

Unless we provide otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control).

Unless we provide otherwise in the applicable prospectus supplement, the debt securities will not contain any restrictive covenants, including covenants restricting us or any of our subsidiaries from incurring, issuing, assuming or guarantying any indebtedness secured by a lien on any of our or our subsidiaries’ property or capital stock, or restricting us or any of our subsidiaries from entering into any sale and leaseback transactions.

Unless we provide otherwise in the applicable prospectus supplement, nothing contained in the indenture or in the debt securities shall prevent us from engaging in any consolidation or merger with or into any other person or persons (whether or not affiliated with us), or successive consolidations or mergers in which either we will be the continuing entity or we or our successor or successors shall be a party or parties, or shall prevent any sale, conveyance, transfer or lease of all or substantially all of our property, to any other person (whether or not affiliated with us); provided, however, that the following conditions are met:

Unless we provide otherwise in the applicable prospectus supplement, “event of default” means with respect to any series of debt securities, any of the following:

No event of default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an event of default with respect to any other series of debt securities. (Section 6.1) An event of default may also be an event of default under our bank credit agreements or other debt securities in existence from time to time and under certain guaranties by us of any subsidiary indebtedness. In addition, certain events of default or an acceleration under the indenture may also be an event of default under some of our other indebtedness outstanding, if any, from time to time.

Unless we provide otherwise in the applicable prospectus supplement, if an event of default with respect to debt securities of any series at the time outstanding occurs and is continuing (other than certain events of our bankruptcy, insolvency or reorganization), then the trustee or the holders of not less than a majority in principal amount of the outstanding debt securities of that series may, by written notice to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and premium of all debt securities of that series. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) and premium of all outstanding debt securities will automatically become and be immediately due and payable without any declaration or other act by the trustee or any holder of outstanding debt securities.

At any time after the principal amount of and premium, if any, and interest on the debt securities shall have been so declared and payable, but before any judgment or decree for the payment of the monies due has been obtained or entered, the holders of a majority in aggregate principal amount of the debt securities then outstanding on behalf of the holders of all of the debt securities then outstanding may waive all events of default or events which, after notice or lapse of time, or both, would be events of default, rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal and premium with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) For information as to waiver of defaults see the discussion under “Modification and Waiver” below. We refer you to the prospectus supplement

relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of the discount securities upon the occurrence of an event of default and the continuation of an event of default.

The indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of outstanding debt securities, unless the trustee receives indemnity or security reasonably satisfactory to it against any loss, liability or expense. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

Unless we provide otherwise in the applicable prospectus supplement, no holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

Notwithstanding the foregoing, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of and premium, if any, and interest, if any, on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

The indenture requires us, within 90 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any default or event of default (except in payment on any debt securities of that series) with respect to debt securities of that series if it in good faith determines that withholding notice is in the interest of the holders of those debt securities. (Section 7.5)

Unless we provide otherwise in the applicable prospectus supplement, we and the trustee may modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We and the trustee may not make any modification or amendment without the consent of the holder of each affected debt security then outstanding if that amendment will:

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may, on behalf of the holders of all debt securities of that series, waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of the outstanding debt securities of any series may, on behalf of the holders of all the debt securities of that series, waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series or in respect of a covenant or provision of the indenture which cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless the terms of the applicable series of debt securities provide otherwise, we may be discharged from any and all obligations in respect of the debt securities of any series (except for certain obligations to register the transfer or exchange of debt securities of the series, to replace stolen, lost or mutilated debt securities of the series, and to maintain paying agencies and certain provisions relating to the treatment of funds held by paying agents). We will be so discharged upon the deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, foreign government obligations (as described at the end of this section), that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent registered public accountants to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of such payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an officers’ certificate and an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that holders of the debt securities of such series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amount and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless the terms of the applicable series of debt securities provide otherwise, upon compliance with certain conditions, we may omit to comply with the restrictive covenants contained in Sections 4.2 (SEC Reports), 4.3 through 4.6 (Compliance Certificate; Stay, Extension and Usury Laws; Corporate Existence; Taxes) and Section 5.1 (When Company May Merge, Etc.) of the indenture, as well as any additional covenants contained in a supplement to the indenture, a board resolution or an officers’ certificate delivered pursuant to the indenture.

Covenant Defeasance and Events of Default. In the event we exercise our option not to comply with certain covenants of the indenture with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amount of money and/or U.S. government obligations or foreign government obligations on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. However, we will remain liable for those payments.

“Foreign government obligations” means, with respect to debt securities of any series that are denominated in a currency other than U.S. dollars:

The debt securities may be exchanged for or converted into shares of common stock, shares of preferred stock or other securities. The terms, if any, on which the debt securities may be exchanged for or converted will be set forth in the applicable prospectus supplement. Such terms may include provisions for conversion, either mandatory, at the option of the holder or at our option, in which case the number of shares of common stock, preferred stock or other securities to be received by the holders of the debt securities would be calculated as of a time and in the manner stated in the prospectus supplement.

The internal law of the State of New York will govern and be used to construe the indenture and the debt securities without giving effect to applicable principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby. (Section 10.10)

We have authority to issue 10,000,000 shares of preferred stock, par value $0.001 per share, none of which are outstanding as of May 3, 2011.

The following description of the terms of the preferred stock sets forth certain general terms and provisions of the preferred stock to which any prospectus supplement may relate and will apply to the preferred stock offered by this prospectus unless we provide otherwise in the applicable prospectus supplement. The applicable prospectus supplement for a particular series of preferred stock may specify different or additional terms. The description of certain provisions of the preferred stock set forth below and in any prospectus supplement does not purport to be complete and is subject to and qualified in its entirety by reference to our certificate of incorporation and the certificate of designations relating to each series of the preferred stock.

Under our certificate of incorporation, our board of directors is authorized without further stockholder action to provide for the issuance of up to the remaining authorized but unissued shares of our preferred stock, in one or more series, with such voting powers, full or limited, and with such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, as shall be stated in the resolution or resolutions providing for the issue of a series of such stock adopted, at any time or from time to time, by our board of directors. As used in this prospectus, the term “board of directors” includes any duly authorized committee thereof. The issuance of the preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation and could have the effect of delaying, deferring or preventing a change in control.

The preferred stock shall have the dividend, liquidation, redemption and voting rights set forth below unless we provide otherwise in a prospectus supplement relating to a particular series of the preferred stock. Reference is made to the prospectus supplement relating to the particular series of the preferred stock offered thereby for specific terms, including:

The preferred stock will, when issued, be fully paid and nonassessable and will have no preemptive rights. The rights of the holders of each series of the preferred stock will be subordinate to those of our general creditors.

Holders of the preferred stock of each series will be entitled to receive, when, as and if declared by our board of directors, out of our funds legally available therefor, cash dividends on such dates and at such rates as set forth in, or as are determined by the method described in, the prospectus supplement relating to such series of the preferred stock. Such rate may be fixed or variable or both. Each such dividend will be payable to the holders of record as they appear on our stock books on such record dates, fixed by our board of directors, as specified in the prospectus supplement relating to such series of preferred stock.

Such dividends may be cumulative or noncumulative, as provided in the prospectus supplement relating to such series of preferred stock. If our board of directors fails to declare a dividend payable on a dividend payment date on any series of preferred stock for which dividends are noncumulative, then the right to receive a dividend in respect

of the dividend period ending on such dividend payment date will be lost, and we will have no obligation to pay any dividend for such period, whether or not dividends on such series are declared payable on any future dividend payment dates. Dividends on the shares of each series of preferred stock for which dividends are cumulative will accrue from the date on which we initially issue shares of such series.

Bank credit agreements that we may enter into from time to time and debt securities that we may issue from time to time may restrict our ability to declare or pay dividends on our capital stock. Unless otherwise specified in the applicable prospectus supplement, so long as the shares of any series of the preferred stock are outstanding, unless:

we may not declare any dividends on any shares of our common stock or any of our other stock ranking as to dividends or distributions of assets junior to such series of preferred stock (we refer to this common stock and any such other stock as junior stock), or make any payment on account of, or set apart money for, the purchase, redemption or other retirement of, or for a sinking or other analogous fund for, any shares of junior stock or make any distribution in respect of any shares of junior stock, whether in cash or property or in obligations of our stock, other than in junior stock which is neither convertible into, nor exchangeable or exercisable for, any of our securities other than junior stock.

Unless otherwise specified in the applicable prospectus supplement, in the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, the holders of each series of the preferred stock will be entitled to receive out of our assets available for distribution to stockholders, before any distribution of assets is made to the holders of common stock or any other shares of our stock ranking junior as to such distribution to such series of the preferred stock, but after any required distributions to holders of any shares of our stock ranking senior as to such distribution to such series of preferred stock, the amount set forth in the prospectus supplement relating to such series of the preferred stock. If, upon our voluntary or involuntary liquidation, dissolution or winding up and after required distribution of our assets to holders of any shares of our stock ranking senior as to such distribution to the preferred stock of a particular series, the amounts payable with respect to the preferred stock of such series and any other shares of our preferred stock, including any other series of the preferred stock, ranking as to any such distribution on a parity with such series of the preferred stock are not paid in full, the holders of the preferred stock of such series and of such other shares of our preferred stock will share ratably in any such distribution of our assets in proportion to the full respective preferential amounts to which they are entitled. After payment to the holders of the preferred stock of each series of the full preferential amounts of the liquidating distribution to which they are entitled, unless we provide otherwise in the applicable prospectus supplement, the holders of each such series of the preferred stock will be entitled to no further participation in any distribution of our assets.

A series of the preferred stock may be redeemable, in whole or from time to time in part, at our option, and may be subject to mandatory redemption pursuant to a sinking fund or otherwise, in each case upon terms, at the times and at the redemption prices set forth in the prospectus supplement relating to such series. Shares of the preferred stock redeemed by us will be restored to the status of authorized but unissued shares of our preferred stock.

In the event that fewer than all of the outstanding shares of a series of the preferred stock are to be redeemed, whether by mandatory or optional redemption, the number of shares to be redeemed will be determined by lot or pro rata, subject to rounding to avoid fractional shares, as may be determined by us or by any other method as may be

determined by us in our sole discretion to be equitable. From and after the redemption date, unless default is made by us in providing for the payment of the redemption price plus accumulated and unpaid dividends, if any, dividends will cease to accumulate on the shares of the preferred stock called for redemption and all rights of the holders thereof, except the right to receive the redemption price plus accumulated and unpaid dividends, if any, will cease.

Unless otherwise specified in the applicable prospectus supplement, so long as any dividends on shares of any series of the preferred stock or any other series of our preferred stock ranking on a parity as to dividends and distribution of assets with such series of the preferred stock are in arrears, no shares of any such series of the preferred stock or such other series of our preferred stock will be redeemed, whether by mandatory or optional redemption, unless all such shares are simultaneously redeemed, and we will not purchase or otherwise acquire any such shares; provided, however, that the foregoing will not prevent the purchase or acquisition of such shares pursuant to a purchase or exchange offer made on the same terms to holders of all such shares outstanding.

The terms, if any, on which shares of the preferred stock of any series may be exchanged for or converted into shares of common stock, another series of the preferred stock or any other security will be set forth in the applicable prospectus supplement. Such terms may include provisions for conversion, either mandatory, at the option of the holder or at our option, in which case the number of shares of common stock, the shares of another series of the preferred stock or the amount of any other securities to be received by the holders of the preferred stock would be calculated as of a time and in the manner stated in the prospectus supplement.

Except as indicated in a prospectus supplement relating to a particular series of the preferred stock, or except as required by applicable law, the holders of the preferred stock will not be entitled to vote for any purpose.

Our amended and restated certificate of incorporation authorizes the issuance of up to 140,000,000 shares of our common stock, par value $0.001 per share. As of May 3, 2011 there were 83,972,040 shares of our common stock, options to purchase 8,089,940 shares of common stock and warrants to purchase 9,200,372 shares of common stock outstanding.

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors, provided, however, that except as otherwise required by law, holders of common stock are not entitled to vote on any amendment to the certificate of incorporation that relates solely to the terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon by law or pursuant to the certificate of incorporation. No holder of our common stock has cumulative voting rights. Accordingly, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose.

Holders of common stock have no preemptive rights or conversion rights or other subscription rights, and there are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are, and the shares of common stock offered by us in this offering, when issued and paid for, will be fully paid and non-assessable. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock which we may designate in the future.

Our common stock is subject to certain limitations on ownership and transfer. See “Certain Provisions of Delaware Law and of the Company’s Certificate of Incorporation and Bylaws” below.

Our common stock is listed on the Nasdaq Capital Market under the symbol “CORT”.

The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust Company.

As of May 3, 2011, there were warrants to purchase 9,200,372 shares of common stock outstanding.

We may issue debt warrants to purchase debt securities, as well as equity warrants to purchase preferred stock or common stock. The warrants may be issued independently or together with any securities and may be attached to or separate from the securities. If the warrants are issued pursuant to warrant agreements, we will so specify in the prospectus supplement relating to the warrants being offered pursuant to the prospectus supplement. The following description of warrants will apply to the warrants offered by this prospectus unless we provide otherwise in the applicable prospectus supplement. The applicable prospectus supplement for a particular series of warrants may specify different or additional terms.

The applicable prospectus supplement will describe the terms of debt warrants offered, the warrant agreement relating to the debt warrants and the debt warrant certificates representing the debt warrants, including the following:

Debt warrant certificates will be exchangeable for new debt warrant certificates of different denominations, and debt warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement. Prior to the exercise of their debt warrants, holders of debt warrants will not have any of the rights of holders of the debt securities purchasable upon exercise and will not be entitled to payment of principal of or any premium, if any, or interest on the debt securities purchasable upon exercise.

The applicable prospectus supplement will describe the following terms of equity warrants offered:

Holders of equity warrants will not be entitled, by virtue of being such holders, to vote, consent, receive dividends, receive notice as stockholders with respect to any meeting of stockholders for the election of our directors or any other matter, or to exercise any rights whatsoever as our stockholders.

The exercise price payable and the number of shares of common stock or preferred stock purchasable upon the exercise of each equity warrant will be subject to adjustment in certain events, including the issuance of a stock dividend to holders of common stock or preferred stock or a stock split, reverse stock split, combination, subdivision or reclassification of common stock or preferred stock. In lieu of adjusting the number of shares of common stock or preferred stock purchasable upon exercise of each equity warrant, we may elect to adjust the number of equity warrants. No adjustments in the number of shares purchasable upon exercise of the equity warrants will be required until cumulative adjustments require an adjustment of at least 1% thereof. We may, at our option, reduce the exercise price at any time.

No fractional shares will be issued upon exercise of equity warrants, but we will pay the cash value of any fractional shares otherwise issuable. Notwithstanding the foregoing, in case of any consolidation, merger, or sale or conveyance of our property as an entirety or substantially as an entirety, the holder of each outstanding equity warrant shall have the right to the kind and amount of shares of stock and other securities and property, including cash, receivable by a holder of the number of shares of common stock or preferred stock into which the equity warrant was exercisable immediately prior to the transaction.

Each warrant will entitle the holder to purchase for cash such principal amount of securities or shares of stock at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the warrants offered thereby. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the prospectus supplement relating to the warrants offered thereby. After the close of business on the expiration date, unexercised warrants will become void.

The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Upon receipt of payment and the taking of other action specified in the applicable prospectus supplement, we will, as soon as practicable, forward the securities purchasable upon exercise. If less than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

The following paragraphs summarize certain provisions of the Delaware General Corporation Law and our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws. The summary does not purport to be complete and is subject to and qualified in its entirety by reference to the Delaware General Corporation Law and to our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, copies of which are exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.”

We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. This law prohibits a publicly-held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless:

In general, Section 203 defines an “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Some provisions of Delaware law and our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could make the following transactions more difficult:

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids and to promote stability in our management. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.
