INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated into this prospectus by reference include forward-looking statements within the meaning of sections 27A of the Securities Act and 21E of the Exchange Act. All statements, other than statements of historical facts, included in this prospectus that address activities, events or developments that we expect, project, believe or anticipate will or may occur in the future are forward-looking statements. These statements can be identified by the use of forward looking terminology including “may,” “believe,” “anticipate,” “expect,” “estimate,” “continue,” “should” or other similar words.

Forward-looking statements are not guarantees of performance. We have based these statements on our assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe are appropriate in the circumstances. No assurance can be given that these assumptions are accurate. Moreover, these statements are subject to a number of risks and uncertainties. Important factors that could cause our actual results to differ materially from the expectations reflected in our forward-looking statements include those described under “Risk Factors” in Item 1A and elsewhere in our most recent Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q, and, among others, the Company’s ability to generate sufficient cash flows from operations, proceeds from equity issuances and debt financings, and proceeds from the sale of assets to satisfy its short and long-term debt obligations and to fund the Company’s acquisitions and capital improvement projects to expand, redevelop, and/or reposition its senior living communities; increases in market interest rates that increase the cost of certain of its debt obligations; increased competition for, or a shortage of, skilled workers, including due to general labor market conditions, along with wage pressures resulting from such increased competition, low unemployment levels, use of contract labor, minimum wage increases and/or changes in overtime laws; the Company’s ability to obtain additional capital on terms acceptable to it; the Company’s ability to extend or refinance its existing debt as such debt matures; the Company’s compliance with its debt agreements, including certain financial covenants, and the risk of cross-default in the event such non-compliance occurs; the Company’s ability to complete acquisitions and dispositions upon favorable terms or at all, including the possibility that the expected benefits and the Company’s projections related to such acquisitions may not materialize as expected; the risk of oversupply and increased competition in the markets which the Company operates; the Company’s ability to improve and maintain controls over financial reporting and remediate the identified material weakness discussed in our recent Quarterly and Annual Reports filed with the SEC; the cost and difficulty of complying with applicable licensure, legislative oversight, or regulatory changes; risks associated with current global economic conditions and general economic factors such as inflation, the consumer price index, commodity costs, fuel and other energy costs, competition in the labor market, costs of salaries, wages, benefits, and insurance, interest rates, and tax rates, the impact from or the potential emergence and effects of a future epidemic, pandemic, outbreak of infectious disease or other health crisis; and changes in accounting principles and interpretations.

Other factors described herein, or factors that are unknown or unpredictable, could also have a material adverse effect on future results.

All subsequent written and oral forward-looking statements attributable to us or to persons acting on our behalf are expressly qualified in their entirety by the foregoing. In light of these risks, uncertainties and assumptions, the events anticipated by our forward-looking statements may not occur, and you should not place any undue reliance on any of our forward-looking statements. Our forward-looking statements speak only as of the date made, and we undertake no obligation to update or revise our forward-looking statements, whether as a result of new information, future events or otherwise.

At the second closing, which occurred on March 22, 2024, the Company issued and sold the remaining 1,675,440 shares of common stock to the Investors and Conversant D and received additional gross cash proceeds of approximately $15.9 million.

The Securities Purchase Agreement also provides that, as soon as reasonably practicable following the second closing of the Private Placement and no later than September 30, 2024, the Company will use its commercially reasonable efforts to prepare and file with the SEC a registration statement of the Company registering the resale of all of the shares of common stock sold pursuant to the Securities Purchase Agreement. This registration statement is being filed to satisfy such obligations.

The foregoing description of the Securities Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Securities Purchase Agreement, a copy of which the Company filed with the SEC as Exhibit 10.1 to a Current Report on Form 8-K on February 6, 2024.

DESCRIPTION OF CAPITAL STOCK

The following is a summary description of the rights of our common stock and related provisions of our Amended and Restated Certificate of Incorporation, as amended, or our Certificate of Incorporation, and our Second Amended and Restated Bylaws, as amended, or our Bylaws. The following description of our common stock is intended as a summary only and is qualified in its entirety by reference to our Certificate of Incorporation and our Bylaws, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part.

Authorized Capitalization

As of September 13, 2024, our authorized capital stock consisted of 30,000,000 shares of common stock, par value $0.01 per share, of which 19,070,277 shares were issued and outstanding, and 15,000,000 shares of preferred stock, par value $0.01 per share, of which 41,250 shares have been designated as Series A Preferred Stock (the “Series A Preferred Stock”). Our Series A Convertible Preferred Stock was issued in a private placement pursuant to Section 4(a)(2) of the Securities Act and has not been registered pursuant to Section 12 of the Exchange Act. As of September 13, 2024, there were no shares of our preferred stock issued and outstanding, except with respect to our Series A Preferred Stock, of which 41,250 shares were issued and outstanding.

Common Stock

Subject to the provisions of our Certificate of Incorporation and limitations prescribed by law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded, we may issue our common stock from time to time upon such terms and for such consideration as may be determined by our Board. Generally, the issuance of common stock, up to the aggregate amounts authorized by our Certificate of Incorporation and any limitations prescribed by law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded, will not require approval of our stockholders.

Voting Rights. The holders of our common stock are entitled to one vote per share on all matters to be voted on by stockholders generally, including the election of directors. There are no cumulative voting rights, meaning that the holders of a majority of the shares voting for the election of directors can elect all of the directors standing for election.

Dividend Rights. The holders of our common stock are entitled to receive dividends (payable in cash, stock or otherwise), subject to any rights and preferences of any outstanding preferred stock, but only when and as declared by our Board out of the assets legally available for dividend payments.

Liquidation Rights. In the event of any liquidation, dissolution or winding up of our company, after there is paid to or set aside for the holders of any class of stock having preference over our common stock the full amount to which such holders are entitled, then the holders of the common stock, shall be entitled, after payment or provision for payment of all debts and liabilities of our company, to receive the remaining assets of our company available for distribution.

Other Matters. Our common stock carries no preemptive or other subscription rights to purchase shares of our stock and is not convertible, redeemable or assessable or entitled to the benefits of any sinking fund.

Our common stock is listed on the New York Stock Exchange and trades under the ticker symbol “SNDA.” Our transfer agent and registrar is Computershare Trust Company, N.A.

The rights, powers, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of any series of our preferred stock.

13

Preferred Stock

Subject to the provisions of our Certificate of Incorporation and limitations prescribed by law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded, we may issue our preferred stock in one or more series from time to time upon such terms and for such consideration as may be determined by our Board. Generally, the issuance of preferred stock, up to the aggregate amounts authorized by our Certificate of Incorporation and any limitations prescribed by law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded, will not require approval of our stockholders. Our Board has the authority to determine the number of shares of, and the rights, preferences and limitations of, each series of preferred stock, including, without limitation, the dividend rights, voting powers, preemptive rights, conversion or exchange rights, redemption rights, and liquidation preferences of any series of preferred stock.

Series A Preferred Stock

The rights, preferences, privileges and restrictions of shares of the Series A Preferred Stock have been fixed in a Certificate of Designation, Rights and Privileges of Series A Convertible Preferred Stock (the “Series A Certificate of Designation”) and the material provisions are described below. The following description of our Series A Preferred Stock is intended as a summary only and does not purport to be complete, and is qualified in its entirety by reference to the Series A Certificate of Designation, our Certificate of Incorporation and our Bylaws, which are filed as exhibits to the registration statement of which this prospectus forms a part, and to the applicable provisions of Delaware law. We urge you to read the Series A Certificate of Designation because it, and not this description, defines the rights of holders of shares of Series A Preferred Stock.

With respect to payment of dividends and distribution of assets upon liquidation, dissolution or winding up of the Company, the Series A Preferred Stock ranks (i) senior to common stock and all other classes and series of capital stock of the Company that do not expressly rank on a parity basis with or senior to the Series A Preferred Stock (“Junior Stock”), (ii) on a parity basis with each other class or series of capital stock of the Company the terms of which expressly provide that such class or series ranks on a parity basis with the Series A Preferred Stock as to dividends or rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company (“Parity Stock”) and (iii) junior to each other class or series of capital stock of the Company authorized, classified or reclassified, the terms of which expressly provide that such class or series ranks senior to the Series A Preferred Stock as to dividends or rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company (“Senior Stock”) and to all existing and future indebtedness and other non-equity claims on the Company.

Shares of the Series A Preferred Stock are entitled to participate on an as-converted basis in common stock dividends (“Participating Dividends”). In addition, each holder of the Series A Preferred Stock is entitled to receive, when, as and if authorized and declared by our Board, dividends accruing daily on the basis of twelve 30-day months and a 360-day year, at a per annum rate of 11.00% of the Liquidation Preference per share of Series A Preferred Stock, which will be either paid in cash or paid in kind as an increase to the Liquidation Preference of the Series A Preferred Stock (“Preferred Dividends”). The Preferred Dividends are cumulative, whether or not declared, compound quarterly and are paid quarterly in arrears on the last day of March, June, September and December in each year, commencing on the first such date following the date of issuance. So long as any shares of Series A Preferred Stock remain outstanding, unless full dividends on all outstanding shares of Series A Preferred Stock have been declared and paid in cash, the Company will be prohibited from declaring any dividends on, or making any distributions relating to, Junior Stock or Parity Stock, subject to certain exceptions.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, the holders will be entitled, out of assets legally available therefor, before any distribution or payment out of the assets of the Company may be made to or set aside for the holders of any Junior Stock and subject to

14

the rights of the holders of any Senior Stock or Parity Stock and the rights of the Company’s existing and future creditors, to receive in full a liquidating distribution in cash and in the amount per share of Series A Preferred Stock equal to the greater of (i) the Liquidation Preference and (ii) the amount such holders would have received had such holders, immediately prior to such voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, converted such shares of Series A Preferred Stock into common stock. The “Liquidation Preference” with respect to any share of Series A Preferred Stock will be $1,000 per share, plus the sum of any Preferred Dividends paid in the form of an increase in the Liquidation Preference of such share, plus the sum of all accrued and unpaid Preferred Dividends and Participating Dividends.

Holders of the Series A Preferred Stock are entitled to vote with the holders of the common stock on all matters submitted to a vote of stockholders of the Company, except as otherwise provided in the Series A Certificate of Designation or as required by applicable law, voting together with the holders of common stock as a single class. Each holder is entitled to a number of votes in respect of the shares of Series A Preferred Stock owned of record by it equal to the number of shares of common stock into which such shares of Series A Preferred Stock could be converted as of the record date for the determination of stockholders entitled to vote on such matters or, if no such record date is established, as of the date such vote is taken or any written consent of stockholders is solicited.

For so long as any shares of the Series A Preferred Stock are outstanding the prior affirmative vote of at least a majority of the then-issued and outstanding shares of Series A Preferred Stock, voting as a separate class, will be required to (i) amend the Certificate of Incorporation or Bylaws in a manner adverse to the Series A Preferred Stock, (ii) amend the Series A Certificate of Designation, (iii) authorize or increase the number of authorized shares of Parity Stock or Senior Stock, and (iv) solely for so long as Conversant A (as defined below) has the consent rights set forth in the Investor Rights Agreement, incur indebtedness if the aggregate amount of indebtedness of the Company and its subsidiaries immediately after such incurrence is in excess of 105% of the aggregate amount of indebtedness of the Company and its subsidiaries in the prior calendar year as of December 31.

If a Change of Control (as defined in the Series A Certificate of Designation) occurs, then each holder will have the right to require the Company to repurchase in whole or in part such holder’s Series A Preferred Stock for a cash purchase price equal to the Change of Control Price (as defined below). Further, if a Change of Control occurs in which the Change of Control Price in respect of a share of Series A Preferred Stock exceeds an amount equal to 150% of the Liquidation Preference in respect of such share of Series A Preferred Stock, the Company will have the right, at its sole option, to redeem all, but not less than all, of the outstanding shares of Series A Preferred Stock at an amount in cash equal to the greater of (A) 100% of the Liquidation Preference for such share and (B) the fair market value of the property such holder would have received in respect of the number of shares of common stock that would have been issuable upon conversion of such share of Series A Preferred Stock in connection with the Change of Control (the “Change of Control Price”).

The Series A Preferred Stock is redeemable, in whole or in part, at the option of the Company at any time (i) on or after the forty-two (42) month anniversary (and before the seventh anniversary) of the Closing Date (as defined below), at a cash redemption price per share of Series A Preferred Stock equal to the greater of (A) 100% of the Liquidation Preference as of the date fixed for redemption thereof and (B) an amount equal to (1) the number of shares of common stock issuable upon conversion of such share of Series A Preferred Stock as of the redemption date multiplied by (2) the VWAP (as defined in the Series A Certificate of Designation) of the common stock for the 30 trading days immediately preceding (and not including) the date on which notice of such redemption is given and (ii) on or after the seventh anniversary of the Closing Date, at a redemption price per share equal to 100% of the Liquidation Preference as of the redemption date. In case of any redemption of only part of the shares of the Series A Preferred Stock at the time outstanding, the shares to be redeemed will be selected pro rata among holders. The Company is only permitted to redeem the Series A Preferred Stock in part if (i) the aggregate cash redemption price is at least $5 million and (ii) immediately following such partial redemption, (a) Conversant A, Conversant B and their affiliates beneficially own at least 17% of the outstanding

15

shares of common stock on an as-converted basis, or (b) no shares of Series A Preferred Stock will remain outstanding.

Each holder has the right to convert (an “Optional Conversion”) each share of such holder’s Series A Preferred Stock at any time into (i) the number of shares of common stock equal to the quotient of (a) the Liquidation Preference divided by (b) the Conversion Price (as defined below) as of the applicable conversion date and (ii) cash in lieu of fractional shares. The Company has the right, exercisable at its option, to designate any business day on or after the third anniversary of the Closing Date as a conversion date for the conversion of all, but not less than all of the outstanding shares of Series A Preferred Stock, but only if the VWAP per share of common stock exceeds 150% of the Conversion Price for the 30 consecutive trading days immediately preceding the date the Company gives notice of such election to convert shares of Series A Preferred Stock (a “Mandatory Conversion”). In the case of a Mandatory Conversion, each share of Series A Preferred Stock then outstanding that is to be converted pursuant to such Mandatory Conversion will be converted into (i) the number of shares of common stock equal to the quotient of (a) the Liquidation Preference divided by (b) the Conversion Price as of the applicable conversion date and (ii) cash in lieu of fractional shares. The “Conversion Price” is initially $40.00 per share of common stock; provided, that the Conversion Price is subject to customary anti-dilution adjustments as provided in the Series A Certificate of Designation. If any such event occurs, the number of shares of common stock issuable upon conversion may be higher than the initial number of shares designated under the Series A Certificate of Designation.

Outstanding Warrants

In connection with certain financing transactions completed in November 2021, the Company, among other things, issued to Conversant A and Conversant B an aggregate of 1,031,250 warrants each evidencing the right to purchase one share of common stock at a price per share of $40.00, subject to certain adjustments, and with an exercise expiration date of five years after the closing date of such financing transactions.

Registration Rights

Under our retirement and separation agreement with Lawrence A. Cohen, our former Chief Executive Officer, Vice Chairman of the Board and director, we and Mr. Cohen remain subject to and bound by the registration rights agreement set forth in Mr. Cohen’s employment agreement, which entitles Mr. Cohen to certain rights with respect to the registration under the Securities Act of our securities he holds. Under such registration rights agreement, if we propose to register any of our securities under the Securities Act, either for our own account or the account of other security holders, Mr. Cohen is entitled to notice of the registration and has the right to include the securities of ours that he holds in the registration. Mr. Cohen’s registration rights are subject to certain conditions, including the right of any underwriters of these offerings to limit the number of shares included in any of these registrations. We have agreed to pay all expenses related to these registrations, except for underwriting discounts and selling commissions.

In November 2021, the Company, Conversant A and Conversant B entered into the Registration Rights Agreement. Pursuant to the Registration Rights Agreement, the Company filed a shelf registration statement registering the resale of up to 6,941,912 shares of common stock held or issuable to Conversant A and Conversant B and such registration statement was declared effective by the SEC on October 25, 2023. In addition, the Registration Rights Agreement provides that, subject to certain requirements and customary conditions, Conversant A and Conversant B are permitted to make one demand that the Company file a registration statement to register the Registrable Securities and within any 12-month period, one demand that the Company consummate a “takedown” off of any such registration statement. The Registration Rights Agreement also provides Conversant A, Conversant B and their affiliates with “piggy-back” registration rights. The Company is required to bear all expenses incurred in connection with the filing of any such registration statements and any such offerings, other than underwriting discounts and commission on the sale of Registrable Securities.

16

In June 2023, the Company, Conversant A and Conversant B entered into the Commitment Agreement pursuant to which, among other things, the parties agreed that the shares of common stock issued or issuable to Conversant A and Conversant B thereunder will constitute “Registrable Securities” under the Registration Rights Agreement and that the terms of such Registration Rights Agreement will apply mutatis mutandis to such shares. Furthermore, the Company agreed to cooperate in adding such shares of common stock to any shelf registration statement filed with the SEC covering previously unregistered common stock owned or to be owned by Conversant A and Conversant B. The Company registered the resale of all of the 1,417,500 shares of common stock issued or issuable to Conversant A and Conversant B pursuant to the Commitment Agreement (including the shares of common stock issued to Conversant A and Conversant B as a commitment fee) as part of the shelf registration statement discussed above in satisfaction of such obligations.

In February 2024, the Company and the Investors entered into the Securities Purchase Agreement pursuant to which, among other things, the Company agreed to use its commercially reasonable efforts to prepare and file with the SEC a registration statement of the Company registering the resale of the common stock sold pursuant to the Securities Purchase Agreement. This registration statement is being filed to satisfy such obligations.

Anti-Takeover Provisions of Our Certificate of Incorporation and Bylaws and the Delaware General Corporation Laws

Our Certificate of Incorporation and Bylaws and the Delaware General Corporation Laws contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are designed to, among other things, discourage coercive takeover practices and inadequate takeover bids and encourage persons seeking to acquire control of us to first negotiate with our Board in hopes of improving the terms of any such takeover bids.

Authorized but Unissued Capital Stock. We have 30,000,000 authorized shares of common stock and 15,000,000 authorized shares of preferred stock. Due to our authorized but unissued common stock and preferred stock, our Board may be able to discourage or make any attempt to obtain control of us more difficult. If, in the exercise of its fiduciary obligations, our Board determines that a takeover proposal is not in our best interest, the Board could issue a portion of these shares without stockholder approval, subject to any limitations prescribed by law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. These shares could be issued in one or more transactions that might prevent or make the completion of a proposed change of control transaction more difficult or costly by:

In this regard, our Certificate of Incorporation grants our Board broad power to establish the rights, preferences and limitations of the authorized and unissued shares of our preferred stock. For example, our Board could establish one or more series of preferred stock that entitle holders to:

17

Stockholder Action by Written Consent; Special Meetings of Stockholders. Our Certificate of Incorporation and Bylaws provide that any action required or permitted to be taken by our stockholders must be taken at an annual or special meeting of stockholders, and may not be taken by the written consent of our stockholders, unless such consent is unanimous. In addition, our Certificate of Incorporation and Bylaws provide that special meetings of stockholders may, subject to the rights of holders of any series of preferred stock and unless otherwise prescribed by statute, be called only by our Board, the Chairman of our Board or stockholders possessing at least 25% of the voting power of our issued and outstanding voting stock. Stockholders may amend or repeal these provisions of our Certificate of Incorporation and Bylaws only by the affirmative vote of at least two-thirds of the voting power of our issued and outstanding voting stock.

Amendment of our Bylaws. Our Certificate of Incorporation and Bylaws grant our Board the power to adopt, amend and repeal our Bylaws upon the affirmative vote of at least a majority of the whole Board. Our stockholders may also adopt, amend or repeal our Bylaws by the affirmative vote of the holders of at least two-thirds of the voting power of our issued and outstanding voting stock.

Classified Board; Election and Removal of Directors. Our directors are divided into three classes serving staggered three-year terms, with only one class being elected each year by our stockholders. At each annual meeting of stockholders, directors are elected to succeed the class of directors whose terms have expired. Directors may be removed only for cause and by the affirmative vote of a majority of our securities then entitled to vote at an election of directors. A vacancy on our Board may be filled by the affirmative vote of a majority of the directors in office. Any director appointed to fill a vacancy serves for the remainder of the term of the class of directors in which the vacancy occurred. The number of directors on our Board generally will be fixed exclusively by, and may be increased or decreased exclusively by, our Board but in no event will be less than three nor more than nine.

Advance Notice Procedures for Director Nominations and Stockholder Proposals. Our Certificate of Incorporation provides the manner in which stockholders may give notice of business to be brought before an annual meeting of stockholders, including proposed nominations of persons for election to our Board.

Delaware Anti-Takeover Law. We are a Delaware corporation subject to Section 203 of the Delaware General Corporation Law, which regulates corporate acquisitions. Section 203 prevents an “interested stockholder,” which is defined generally as a person who, together with his or her affiliates and associates, owns 15% or more of a corporation’s outstanding voting stock, from engaging in a broad range of “business combinations” with the corporation for three years after becoming an interested stockholder unless:

The above description of Section 203 of the Delaware General Corporation Law is intended as a summary only and is qualified in its entirety by reference to Section 203 of the Delaware General Corporation Law.

Exclusive Forum Selection

Our Bylaws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Company, (b) any action

18

asserting a claim of breach of fiduciary duty owed by any director or officer or other employee or agent of the Company to the Company or the Company’s stockholders, (c) any action asserting a claim against the Company or any director or officer or other employee or agent of the Company arising pursuant to any provision of the Delaware General Corporation Law or the Company’s Certificate of Incorporation or Bylaws, or (d) any action asserting a claim against the Company or any director or officer or other employee or agent of the Company governed by the internal affairs doctrine shall be the federal district court for the District of Delaware (or, if the federal district court for the District of Delaware does not have jurisdiction, the Court of Chancery of the State of Delaware).

Limitation of Liability of Directors and Officers

Our directors and officers will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable, except, if required by Delaware law, for liability:

As a result, neither we nor our stockholders have the right, through stockholders’ derivative suits on our behalf, to recover monetary damages against a director or officer for breach of fiduciary duty as a director or officer, as applicable, including breaches resulting from grossly negligent behavior, except in the situations described above.

19

PLAN OF DISTRIBUTION

The Selling Stockholders and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal trading market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling securities:

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities 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 the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities 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 create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The Selling Stockholders have informed the Company that they do not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities.

20

We agreed to use our commercially reasonable efforts to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by each of the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144 or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Item 15. Indemnification of Directors and Officers

We are incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law empowers a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. Similar indemnity is authorized for such persons against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of any such threatened, pending or completed action or suit 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 provided further that (unless a court of competent jurisdiction otherwise provides) such person shall not have been adjudged liable to the corporation. Any such indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors or by independent legal counsel in a written opinion that indemnification is proper because the indemnitee has met the applicable standard of conduct.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would otherwise have the power to indemnify such person under Section 145. We expect to maintain policies insuring our and our subsidiaries’ officers and directors against certain liabilities for actions taken in such capacities, including liabilities under the Securities Act.

Article Twelfth of our Certificate of Incorporation eliminates the personal liability of each of our directors and officers to us and our stockholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable; provided, however, that such provision does not eliminate or limit the liability (i) for any breach of such director’s or officer’s duty of loyalty to us or our stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Title 8, Section 174 of the Delaware General Corporation Law (pertaining to certain prohibited acts including unlawful payments of

dividends or unlawful stock purchases or redemptions), as the same exists or as such provision may hereafter be amended, supplemented or replaced, (iv) for any transactions from which such director or officer derived an

II-1

improper personal benefit or (v) of an officer in any action by or in the right of the Company. In addition, Article Twelfth provides that each of our directors or officers will not be personally liable to the fullest extent permitted by any amendment to the Delaware General Corporation Law that further limits the liability of a director and officers and is enacted after the adoption of our Certificate of Incorporation.

Article Thirteenth of our Certificate of Incorporation provides that we will indemnify any person who was, is, or is threatened to be made a party to a proceeding by reason of the fact that he or she (i) is or was a director or officer of us or (ii) while a director or officer of us, is or was serving at the request of us as a director, officer, partner, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan, or other enterprise, to the fullest extent permitted under the Delaware General Corporation Law. For purposes of Article Thirteenth, a “proceeding” means any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, arbitrative, or investigative, any appeal in such an action, suit, or proceeding, or any inquiry or investigation that could lead to such an action, suit, or proceeding. Such right includes the right to be paid by us for expenses (including without limitation attorneys’ fees) actually and reasonably incurred by such individual in defending any such proceeding in advance of its final disposition to the maximum extent permitted under the Delaware General Corporation Law.

The foregoing discussion of the Delaware General Corporation Law and our Certificate of Incorporation is not intended to be exhaustive and is qualified in its entirety by reference to such statute and such Certificate of Incorporation filed with the SEC.

We have obtained a directors’ and officers’ liability insurance policy insuring our directors and officers against certain losses resulting from wrongful acts committed by them as our directors and officers, including liabilities arising under the Securities Act.

Provided, however, that subparagraphs (1)(i), (1)(ii), and (1)(iii) above do not apply if information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 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.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.
