24,868,028 Shares
Common Stock
Offered by the Selling Stockholders
This prospectus relates to the proposed resale or other disposition by the selling stockholders identified herein (the "Selling Stockholders"), of up to (i) 10,425,531 shares ("Merger Conversion Shares") of our common stock, par value $0.0001 per share ("Common Stock"), issuable upon the conversion of 10,425.531 shares ("Merger Preferred Shares") of our Series B Non-Voting Convertible Preferred Stock, par value $0.0001 per share ("Series B Preferred Stock"), (ii) 14,440,395 shares of Common Stock (the "Private Placement Conversion Shares") issuable upon the conversion of 14,440.395 shares of our Series B Preferred Stock (the "Private Placement Preferred Shares") and (iii) 2,102 shares of Common Stock (the "Warrant Conversion Shares") issuable upon exercise of a warrant (the "Warrant") to purchase 2.1020 shares of Series B Preferred Stock (the "Warrant Preferred Shares"), which will be exercisable for shares of Common Stock upon conversion of the Series B Preferred Stock. Subject to receiving approval by our stockholders of the issuance of shares of Common Stock upon conversion of Series B Preferred Stock and the change of control of our company in accordance with the Nasdaq Stock Market LLC ("Nasdaq") listing rules (the "Conversion Proposal") and of a certificate of amendment to our amended and restated certificate of incorporation to increase the number of authorized shares of Common Stock from 12,500,000 to 300,000,000 (the "Authorized Share Proposal" and, together with the Conversion Proposal, the "Required Company Stockholder Matters") and certain beneficial ownership limitations set by each preferred stockholder, each share of Series B Preferred Stock will automatically convert into 1,000 shares of Common Stock. The shares of Common Stock registered by this prospectus are referred to herein as the "Resale Shares."
The Merger Preferred Shares were issued to former stockholders of Faeth Holdings Therapeutics, Inc., a Delaware corporation ("Faeth HoldCo"), and the Warrant held by a former equityholder of Faeth Therapeutics, LLC, a Delaware limited liability company and wholly owned subsidiary of Faeth HoldCo ("Faeth Subsidiary" and, together with Faeth HoldCo, "Faeth" or "Faeth Therapeutics") was assumed by us and converted into a warrant to purchase our Series B Preferred Stock, in connection with our acquisition (the "Acquisition") of Faeth Therapeutics, which closed on February 17, 2026. The Private Placement Preferred Shares were issued and sold to accredited investors in a private placement (the "2026 Private Placement" and, together with the Acquisition and the other transactions and actions contemplated by the Merger Agreement, the "Acquisition Transactions"), which closed on February 20, 2026. We are not offering or selling any Resale Shares under this prospectus and will not receive any of the proceeds from the sale or other disposition of Resale Shares by the Selling Stockholders.
The Selling Stockholders may sell the Resale Shares on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, on the over-the-counter market, in one or more transactions otherwise than on these exchanges or systems, such as privately negotiated transactions, or using a combination of these methods, and at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. See the disclosure under the heading "Plan of Distribution" elsewhere in this prospectus for more information about how the Selling Stockholders may sell or otherwise dispose of their Resale Shares hereunder.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS
This prospectus, including the documents that we incorporate by reference, contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These forward-looking statements involve a number of risks and uncertainties. We caution readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statement. These statements are based on current expectations of future events.
All statements, other than statements of historical facts contained in this prospectus, are forward-looking statements, including, without limitation, statements regarding: the Required Company Stockholder Matters, the Annual Meeting (as defined below), the Nasdaq Listing Application (as defined below), the expected Company name and ticker if the Required Company Stockholder Matters and the Nasdaq Listing Application are approved, our ability to achieve the expected benefits or opportunities with respect to the Acquisition, our future results of operations and financial position, business strategy, our expectations that our cash and cash equivalents, together with the proceeds from the 2026 Private Placement, will enable us to fund our operating expenses and capital expenditure requirements through topline data readouts from both our ongoing Phase 2 trial of PIKTOR in advanced endometrial cancer (Study FTH-PIK-201) and our planned Phase 1b trial of PIKTOR in HR+/HER2- advanced breast cancer (Study FTH-PIK-101), our preclinical and clinical development activities, the potential therapeutic benefits and economic value of our product candidates, and the timing and results of preclinical studies and clinical trials. Forward-looking statements generally relate to future events or our future financial or operating performance. The words "aim," "anticipate," "assume," "can," "continue," "could," "designed to," "estimate," "evaluate," "expect," "explore," "intend," "intended to," "likely," "may," "might," "objective," "ongoing," "plan," "potential," "predict," "project," "pursue," "seek," "should," "to be," "will," and "would," or the negative of such terms or other similar expressions that convey uncertainty of future events or outcomes are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.
These forward-looking statements are subject to a number of risks, uncertainties and assumptions. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Factors that might cause such a difference include those discussed in our most recent Annual Report on Form 10-K, as supplemented and updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that we have filed or will file with the SEC, and in other documents which are incorporated by reference into this prospectus, as well as the risk factors and other information contained in or incorporated by reference into any accompanying prospectus supplement. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus or, in the case of documents referred to or incorporated by reference, the date of those documents.
In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this prospectus. While we believe that such information provides a reasonable basis for these statements, such information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.
All subsequent written or oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events, except as may be required under applicable U.S. securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

PROSPECTUS SUMMARY
This summary may not contain all the information that you should consider before investing in securities. You should read the entire prospectus and the information incorporated by reference in this prospectus carefully, including "Risk Factors" and the financial data and related notes and other information incorporated by reference herein, before making an investment decision.
Company Overview
We are a clinical-stage biotechnology company focused on improving outcomes for cancer patients through multi-node inhibition of critical oncogenic pathways. On February 17, 2026, we completed the acquisition of Faeth Therapeutics, a clinical-stage biotechnology company developing multi-node therapies that target tumor metabolism and signaling. The Acquisition brought Faeth's lead asset, PIKTOR, a proprietary investigational all-oral combination of serabelisib and sapanisertib that inhibits multiple nodes of the PI3K/AKT/mTOR pathway, into our pipeline.
Following the Acquisition, our lead program is PIKTOR, an investigational multi-node inhibitor of the PI3K/AKT/mTOR pathway in development for endometrial and breast cancer. The PI3K/AKT/mTOR pathway is dysregulated in up to 50% of all solid tumors, making it one of the most prevalent therapeutic targets in oncology. Despite this, currently approved therapies - all of which target only a single pathway node - have produced limited clinical benefits, often accompanied by toxicities that have constrained their utilization. Our core scientific thesis is that simultaneously suppressing multiple nodes of a pathway produces deeper, more durable tumor suppression than targeting any single-node alone, which we believe may also enable lower drug dosing, potentially contributing to an improved tolerability profile.
PIKTOR is currently being evaluated in an ongoing Phase 2 trial in second-line advanced endometrial cancer (Study FTH-PIK-201), with topline data anticipated by year-end 2026, and we intend to initiate a Phase 1b trial in HR+/HER2- advanced breast cancer (Study FTH-PIK-101) by the first half of 2026.
Faeth was co-founded in 2019 by Anand Parikh and Oliver Maddocks, PhD, together with scientific founders Lewis Cantley, PhD, the discoverer of the PI3K pathway, Siddhartha Mukherjee, MD, DPhil, Karen Vousden, PhD, Scott Lowe, PhD, and Greg Hannon, PhD. We are led by an experienced management team with expertise spanning cancer biology, translational research, clinical drug development, regulatory affairs and corporate strategy gained through prior roles within both biotechnology and large pharmaceutical companies as well as academia.
Our Pipeline
3
In addition to PIKTOR and the Faeth pipeline programs described above, our pipeline includes programs that preceded the Acquisition. We are completing a Phase 1/2 trial of solnerstotug (formerly SNS-101), our conditionally active monoclonal antibody targeting the immune checkpoint VISTA. As of March 23, 2026, seven patients remain on study in the expansion portion of the trial. We also have three preclinical-stage conditionally active antibody programs: SNS-102 (targeting VSIG4), SNS-103 (targeting CD39), and SNS-201, a bispecific antibody designed to conditionally activate CD28 through monovalent CD28 engagement and bivalent pH-selective VISTA binding.
Recent Developments
On February 17, 2026 (the "Closing"), we completed the acquisition of Faeth Therapeutics in accordance with the terms of the Agreement and Plan of Merger (the "Merger Agreement"), dated February 17, 2026, by and among the Company, Sapphire First Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company ("First Merger Sub"), Sapphire Second Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("Second Merger Sub"), Faeth HoldCo and Faeth Subsidiary, pursuant to which, First Merger Sub merged with and into Faeth HoldCo, pursuant to which Faeth HoldCo was the surviving corporation and became a wholly owned subsidiary of the Company (the "First Merger"). Immediately following the First Merger, Faeth HoldCo merged with and into Second Merger Sub, pursuant to which Second Merger Sub was the surviving entity.
The Acquisition was structured as a stock-for-stock transaction pursuant to which all of Faeth Therapeutics' outstanding equity interests were exchanged based on a fixed exchange ratio for aggregate consideration of 10,497.098 shares of Series B Preferred Stock, each share of which is convertible into 1,000 shares of Common Stock (representing 10,497,098 shares on an as-converted-to-common basis and without giving effect to any beneficial ownership limitations), subject to receipt of approval of the Required Company Stockholder Matters in accordance with Nasdaq listing rules and the beneficial ownership limitations set by each holder, which may be waived by each holder at any time following the approval by Nasdaq of a Nasdaq initial listing application filed in accordance with Nasdaq listing rule 5110(a) (the "Nasdaq Listing Application") and approval of the Required Company Stockholder Matters. In addition, the outstanding warrant to purchase shares of Faeth Subsidiary capital stock was converted into a warrant to purchase an aggregate of 2.1020 shares of Series B Preferred Stock (representing a warrant to purchase 2,102 shares of Common Stock on an as-converted-to-common basis and without giving effect to any beneficial ownership limitations) and all outstanding options to purchase Faeth Subsidiary common stock were assumed by us and converted into options to purchase an aggregate of 252,210 shares of Common Stock. The Series B Preferred Stock was a newly designated series of preferred stock and was intended to have economic rights equivalent to our Common Stock, but with no voting rights. The rights of the Series B Preferred Stock are set forth in the Certificate of Designation of Series B Non-Voting Convertible Preferred Stock (the "Certificate of Designation") that we filed with the Secretary of State of the State of Delaware.
With respect to the Acquisition, we determined that we were the acquiror for accounting purposes under ASC 805-10-25-4 and ASC 805-10-55-11. The primary factors considered were (a) the relative voting rights in the combined entity not resulting in a change of control, (b) the pre-Acquisition members of our board of directors maintained control of our board of directors, and (c) the pre-Acquisition members of senior management remained the same at the closing of the Acquisition Transactions, other than the newly appointed Chief Operating Officer. Next, we considered whether the Acquisition should be defined as a business under ASC 805. ASC 805-10-55-5A through 55-5C describe a screen test to determine whether an acquired set of assets and activities is not a business. We determined that substantially all (greater than 90%) of the fair value of the assets acquired were concentrated in a single asset, PIKTOR, an investigational, proprietary, all-oral combination of serabelisib and sapanisertib that is designed to inhibit multiple nodes of the PI3K/AKT/mTOR pathway through PI3K-alpha and dual mTORC1/2 targeting. Accordingly, we treated the Acquisition as an asset acquisition for accounting purposes.
4
Concurrently with the Acquisition, we entered into a Securities Purchase Agreement (the "Purchase Agreement") with the purchasers named therein (the "Investors"), pursuant to which, on February 20, 2026 (the "PIPE Closing"), we issued and sold an aggregate of 14,440.395 shares of Series B Preferred Stock, each share of which is convertible into 1,000 shares of Common Stock (representing 14,440,395 shares on an as-converted-to-common basis and without giving effect to any beneficial ownership limitations), subject to receipt of approval of the Required Company Stockholder Matters in accordance with Nasdaq listing rules and the beneficial ownership limitations set by each holder, which may be waived by each holder at any time following the approval by Nasdaq of the Nasdaq Listing Application and approval of the Required Company Stockholder Matters, at a price of $13,850 per share of Series B Preferred Stock (or approximately $13.85 per share on an as-converted-to-common basis) for aggregate gross proceeds of approximately $200 million.
On February 17, 2026, we entered into a Registration Rights Agreement (the "RRA") with the Investors. Pursuant to the RRA, we are obligated to prepare and file a resale registration statement with the SEC within 75 calendar days following the closing of the 2026 Private Placement. The RRA also contains customary terms, including an obligation to indemnify the Investors and certain affiliates from certain liabilities relating to any misstatements or omissions in the resale registration statement.
The Acquisition, the 2026 Private Placement and the other transactions and actions contemplated by the Merger Agreement (the "Acquisition Transactions") were approved by our board of directors and the board of directors and stockholders of Faeth Therapeutics. The closings of the Acquisition Transactions were not subject to the approval of Sensei stockholders.
We have filed a definitive proxy statement with the SEC to solicit approval of the Required Company Stockholder Matters, among other matters, at our 2026 annual meeting of our stockholders (the "Annual Meeting"). Except as otherwise required by law (e.g. voting on a change to the authorized shares of Series B Preferred Stock or the rights of such shares as required by the General Corporation Law of the State of Delaware ("DGCL")) and the Certificate of Designation, the Series B Preferred Stock does not have voting rights. For more information on the Series B Preferred Stock, please refer to the Certificate of Designation, which is incorporated by reference herein and attached as Exhibit 3.1 of our Current Report on Form 8-K, filed with the SEC on February 18, 2026.
We have filed the Nasdaq Listing Application with Nasdaq. If the Required Company Stockholder Matters and the Nasdaq Listing Application are approved, it is expected that we will change our name to "Faeth Therapeutics, Inc." and our Common Stock will trade on The Nasdaq Capital Market under the symbol "FTH."
In connection with the execution of the Merger Agreement, Sensei and Faeth Subsidiary entered into stockholder support agreements (the "Support Agreements") with certain of Sensei's officers and directors (solely in their capacities as stockholders), representing 1.5% of the outstanding shares of Common Stock as of April 13, 2026. The Support Agreements provide that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the Required Company Stockholder Matters, the approval of the Company's 2026 Equity Incentive Plan and the Company's 2026 Employee Stock Purchase Plan at the Annual Meeting.
Concurrently and in connection with the execution of the Merger Agreement, certain officers, directors and certain stockholders of Faeth HoldCo as of immediately prior to the Merger, and certain of the directors and officers of Sensei as of immediately prior to the Acquisition entered into lock-up agreements (the "Lock-up Agreements") with Sensei and Faeth Subsidiary, pursuant to which each such stockholder will be subject to a 180-day lockup on the sale or transfer of shares of Common Stock and Series B Preferred Stock held by each such stockholder, subject to certain limited exceptions as set forth in the Lock-Up Agreements.
For more information about the Acquisition Transactions, you should refer to our Current Report on Form 8-K filed with the SEC on February 18, 2026, which is incorporated by reference herein.

Corporate Information
We were originally incorporated as Panacea Pharmaceuticals, Inc., or Panacea, under the laws of the state of Maryland in 1999. In December 2017, we reincorporated in Delaware and changed our name to Sensei Biotherapeutics, Inc. Our principal executive offices are located at 1405 Research Blvd, Rockville, MD 20850. Our telephone number is (240) 243-8000.
Implications of Being an Emerging Growth Company and Smaller Reporting Company
We are an "emerging growth company," as defined in Section 2(a) of the Securities Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act, compliance with any new requirements adopted by the PCAOB, disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and the requirements of holding advisory "say-on-pay" votes on executive compensation and stockholder advisory votes on golden parachute compensation not previously approved. Certain of these reduced reporting requirements and exemptions are also available to us due to the fact that we qualify as a "smaller reporting company" under SEC rules. For instance, smaller reporting companies are not required to obtain an auditor attestation and report regarding management's assessment of internal control over financial reporting, are not required to provide a compensation discussion and analysis, are not required to provide a pay-for-performance graph or CEO pay ratio disclosure and may present only two years of audited financial statements and related MD&A disclosure.
Under the JOBS Act, we will remain an emerging growth company until the earliest of (1) the last day of the fiscal year in which we have more than $1.235 billion in annual revenue; (2) the date we qualify as a "large accelerated filer," with at least $700.0 million of equity securities held by non-affiliates; (3) the issuance, in any three-year period, by our company of more than $1.0 billion in non-convertible debt securities; and (4) December 31, 2026, which is the last day of the fiscal year following the fifth anniversary of the date of the first sale of our Common Stock pursuant to an effective registration statement filed under the Securities Act. Under current SEC rules, however, we will continue to qualify as a "smaller reporting company" for so long as (i) we have a public float (i.e., the market value of common equity held by non-affiliates) of less than $250 million or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and the market value of our Common Stock held by non-affiliates is less than $700 million.
Under the JOBS Act, emerging growth companies also can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected not to "opt out" of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we will adopt the new or revised standard at the time private companies adopt the new or revised standard and will do so until such time that we either (i) irrevocably elect to "opt out" of such extended transition period or (ii) no longer qualify as an emerging growth company. Therefore, the reported results of operations contained in our consolidated financial statements may not be directly comparable to those of other public companies.

Before deciding whether to invest in our securities, you should consider carefully the risks and uncertainties described under the heading "Risk Factors" contained in our most recent Annual Report on Form 10-K, as supplemented and updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that we have filed or will file with the SEC, and in other documents which are incorporated by reference into this prospectus, as well as the risk factors and other information contained in or incorporated by reference into any accompanying prospectus supplement. The risks described in these documents are not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section titled "Cautionary Statement Concerning Forward-Looking Statements."

PLAN OF DISTRIBUTION
The Selling Stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling Resale Shares or interests in Resale Shares received after the date of this prospectus from a Selling Stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their Resale Shares or interests in Resale Shares on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.
The Selling Stockholders may use any one or more of the following methods when disposing of Resale Shares or interests therein:
| |
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; |
| |
block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction; |
| |
purchases by a broker-dealer as principal and resale by the broker-dealer for its account; |
| |
an exchange distribution in accordance with the rules of the applicable exchange; |
| |
privately negotiated transactions; |
| |
short sales and settlement of short sales; |
| |
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; |
| |
broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share; |
| |
a combination of any such methods of sale; and |
| |
any other method permitted pursuant to applicable law. |
The Selling Stockholders may, from time to time, pledge or grant a security interest in some or all of the Resale Shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the Resale Shares, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders also may transfer the Resale Shares in other circumstances, in which case the transferees, pledgees or other successors in interest will be the Selling Stockholders for purposes of this prospectus.
In connection with the sale of Resale Shares or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of Common Stock in the course of hedging the positions they assume. The Selling Stockholders may also sell Resale Shares short and deliver these securities to close out their short positions, or loan or pledge the Resale Shares to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
The aggregate proceeds to the Selling Stockholders from the sale of the Resale Shares offered by them will be the purchase price of the Resale Shares less discounts or commissions, if any. Each of the Selling
29
Stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Resale Shares to be made directly or through agents. We will not receive any of the proceeds from this offering. If the Warrant is exercised for cash, we will receive the net proceeds therefrom.
The Selling Stockholders also may resell all or a portion of the Resale Shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or another available exemption from the registration requirements under the Securities Act.
The Selling Stockholders and any underwriters, broker-dealers or agents that participate in the sale of the Resale Shares or interests therein may be "underwriters" within the meaning of Section 2(a)(11) of the Securities Act (it being understood that the Selling Stockholders shall not be deemed to be underwriters solely as a result of their participation in this offering). Any discounts, commissions, concessions or profit they earn on any resale of the Resale Shares may be underwriting discounts and commissions under the Securities Act. Selling Stockholders who are "underwriters" within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.
To the extent required, the Resale Shares to be sold, the names of the Selling Stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.
In order to comply with the securities laws of some states, if applicable, the Resale Shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Resale Shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.
We have advised the Selling Stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the Selling Stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the Selling Stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the Resale Shares against certain liabilities, including liabilities arising under the Securities Act.
We have agreed to indemnify the Selling Stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the Resale Shares offered by this prospectus.
We have agreed with the Selling Stockholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part to become effective and to remain continuously effective until the earlier of: (i) the date on which the Selling Stockholders shall have resold or otherwise disposed of all the Resale Shares covered by this prospectus and (ii) the date on which the Resale Shares covered by this prospectus no longer constitute "Registrable Securities" as such term is defined in the RRA, such that they may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations and without current public information pursuant to Rule 144 under the Securities Act or any other rule of similar effect.
There can be no assurance that any Selling Stockholder will sell any or all of the Resale Shares registered pursuant to the registration statement of which this prospectus forms a part.

Indemnification of Officers and Directors |
We are incorporated under the laws of the State of Delaware. Section 102 of the Delaware General Corporation Law permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.
Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys' fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.
As permitted by the Delaware General Corporation Law, our certificate of incorporation and bylaws provide that: (i) we are required to indemnify our directors to the fullest extent permitted by the Delaware General Corporation Law; (ii) we may, in our discretion, indemnify our officers, employees and agents as set forth in the Delaware General Corporation Law; (iii) we are required, upon satisfaction of certain conditions, to advance all expenses incurred by our directors in connection with certain legal proceedings; (iv) the rights conferred in the bylaws are not exclusive; and (v) we are authorized to enter into indemnification agreements with our directors, officers, employees and agents.
We have entered into indemnification agreements with each of our directors and executive officers that require us to indemnify them against expenses, judgments, fines, settlements and other amounts that any such person becomes legally obligated to pay (including with respect to a derivative action) in connection with any proceeding, whether actual or threatened, to which such person may be made a party by reason of the fact that
II-1
such person is or was a director or officer of us or any of our affiliates, provided such person acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, our best interests. The indemnification agreements also set forth certain procedures that apply in the event of a claim for indemnification thereunder. At present, no litigation or proceeding is pending that involves any of our directors or officers regarding which indemnification is sought, nor are we aware of any threatened litigation that may result in claims for indemnification.
We maintain a directors' and officers' liability insurance policy. The policy insures directors and officers against unindemnified losses arising from certain wrongful acts in their capacities as directors and officers and reimburses us for those losses for which we have lawfully indemnified the directors and officers. The policy contains various exclusions.

| Item 17. |
Undertakings |
(a) The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Filing Fee Table" in the effective registration statement; and
(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however, that subparagraphs (i),(ii), and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4) That, for the purpose of determining liability under the Securities Act to any purchaser:
II-3
(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(b) That, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
