OUR COMPANY
 
We are the leading provider of leased wide-body freighter aircraft, furnishing outsourced air cargo operating services and solutions to the global air freight industry. As such, we manage and operate the world’s largest fleet of 747 freighters. We provide unique value to our customers by giving them access to highly reliable new production freighters that deliver the lowest unit cost in the marketplace combined with outsourced aircraft operating services that lead the industry in terms of quality and global scale. Our customers include airlines, express delivery providers, freight forwarders, the U.S. military and charter brokers. We provide global services with operations in Asia, the Middle East, Australia, Europe, South America, Africa and North America.
 
We believe that the scale, scope and quality of our outsourced services are unparalleled in our industry. The relative operating cost efficiency of our current 747-400F aircraft and future 747-8F aircraft, including their superior fuel efficiency, capacity and loading capabilities, create a compelling value proposition for our customers.
 
Atlas Air Worldwide Holdings, Inc. is a holding company with a principal, wholly-owned, operating subsidiary, Atlas Air, Inc. (“Atlas Air”). We also have a 51% economic interest and 75% voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”), which, since October 27, 2008, is accounted for under the equity method. On June 28, 2007, Polar issued shares representing a 49% economic interest and a 25% voting interest to DHL Network Operations (USA), Inc. (“DHL”), a subsidiary of Deutsche Post AG (“DP”). In February 2008, we formed Titan Aviation Leasing Limited (“Titan”), a wholly owned subsidiary based in Ireland, for the purpose of dry leasing aircraft and engines.
 
Our primary service offerings are:
 
Freighter aircraft leasing services, which encompass the following:
 
  •  We provide outsourced operating solutions including the provision of crew, maintenance and insurance for the aircraft (hereinafter referred to as “ACMI”), while customers assume fuel, demand and yield risk. ACMI contracts typically range from three to six year periods for 747-400s and shorter periods for 747-200s. Included in ACMI is the provision of outsourced airport-to-airport wide-body cargo aircraft solutions to Polar for the benefit of DHL and other customers, which we refer to as Express Network ACMI services. Through this arrangement, we provide dedicated 747-400 aircraft servicing the requirements of DHL’s global express operations through Polar as well as the requirements of Polar’s other customers;
 
  •  Dry leasing, whereby we provide aircraft and engine leasing solutions to third parties for one or more dedicated aircraft. We provide dry leasing services primarily to Global Supply Systems, a private company in which we own a 49% interest. We have also provided dry leasing services to other third party customers through both Atlas Air and our newly formed leasing subsidiary, Titan.
 
Charter services, which encompass the following:
 
  •  Military charter services, whereby we provide air cargo services for the U.S. Air Mobility Command;
 
  •  Commercial charters, whereby we provide all-inclusive cargo aircraft charters to brokers, freight forwarders, direct shippers and airlines. In addition, we have been providing airport-to-airport air cargo services to freight forwarders and other shipping customers in limited markets since October 2008.
 
AAWW was incorporated in Delaware in 2000. Our principal executive offices are located at 2000 Westchester Avenue, Purchase, New York 10577, and our telephone number is (914) 701-8000.
 
Our website is www.atlasair.com. The information on our website is not a part of this prospectus supplement.
 
Atlas and Polar hold various trademark registrations and have applications for additional registrations pending in several foreign jurisdictions. This prospectus supplement and the documents incorporated herein by reference also include trademarks, trade names and service marks of other companies. Use or display by us of other parties’ trademarks, trade names or service marks is not intended to and does not imply a relationship with, or endorsement or sponsorship of us by, these other parties.

Recent Development
 
Increased Maintenance Expense.  As we have previously disclosed, our maintenance, materials and repairs expense in the first quarter of 2009 was $29.2 million, and such expense in the second quarter of 2009 is expected to be significantly higher. This is primarily a result of the timing of certain expenditures in this period, which we anticipate will include at least three additional “C Checks” on our B747-400 aircraft and four additional engine overhauls. A “C Check” is a high level or “heavy” airframe maintenance check that is generally performed at 18 month intervals.
 
RISK FACTORS
 
Investing in our securities involves risk. You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus supplement and the accompanying prospectus, including the risk factors described below and other risk factors incorporated by reference from our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2008, filed with the SEC on February 26, 2009, as updated by our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2009, filed with the SEC on May 5, 2009, and our other filings with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act filed after such annual report. The risk factors we have described are not the only ones we face. Our operations could also be impaired by additional risks and uncertainties. If any of these risks and uncertainties develop into actual events, our business, financial condition and results of operations could be materially and adversely affected.
 
U.S. citizenship requirements may limit common stock voting rights.
 
Under federal law and Department of Transportation (“DOT”) requirements, we must be owned and actually controlled by “citizens of the United States,” a statutorily defined term requiring, among other things, that not more than 25% of our issued and outstanding voting stock be owned and controlled, directly or indirectly, by non-U.S. citizens. DOT periodically conducts airline citizenship reviews and, if it finds that this requirement is not met, may require adjustment of the rights attendant to the airline’s issued shares.
 
As one means to effect compliance, our certificate of incorporation and bylaws provide that the failure of non-U.S. citizens to register their shares on a separate stock record, which we refer to as the “Foreign Stock Record,” results in a suspension of their voting rights. Our bylaws further limit the number of shares of our capital stock that may be registered on the Foreign Stock Record to 25% of our issued and outstanding shares. Registration on the Foreign Stock Record is made in chronological order based on the date we receive a written request for registration. As a result, if a non-U.S. citizen acquires shares of our common stock and does not or is not able to register those shares on our Foreign Stock Record, they may lose their ability to vote those shares. See “Description of Capital Stock — Foreign Ownership Restrictions” for additional information on the foreign ownership restrictions applicable to the ownership of our shares.
 
Our financial condition may suffer if we experience unanticipated costs or enforcement action as a result of the ongoing Antitrust Division of the United States Department of Justice fuel surcharge investigation and other lawsuits and claims.
 
On February 14, 2006, the Antitrust Division of the United States Department of Justice (“Antitrust Division”) initiated a criminal investigation into the pricing practices of a number of cargo carriers, including Polar Air Cargo LLC (“Polar LLC”), a wholly owned subsidiary of the Company. The Antitrust Division is investigating whether during any part of January 2000 to February 2006 cargo carriers manipulated the market price for air cargo services sold in the U.S. and abroad, through the use of fuel surcharges, in violation of the U.S. federal antitrust laws. Polar LLC’s counsel has been meeting periodically with the Antitrust Division staff. On April 28, 2009, Polar received a letter from the Antitrust Division staff informing it that it is a target of a grand jury investigation in the Northern District of Georgia in connection with the above referenced matters. This means that the Antitrust Division may ask the grand jury to indict Polar at some future time. While the letter was addressed to Polar, we believe it is more properly directed at Polar LLC, because, among other things, Polar was not an operating company during any of the periods subject to the investigation. The staff of the Antitrust Division has, however, to date declined to change the name of the target. As a result of the investigation, the Company and Polar LLC, along with a number of other cargo

carriers, have been named co-defendants in a number of class action suits filed in multiple jurisdictions of the U.S. Federal District Court, and have been named in two civil class action suits in the provinces of Ontario and Quebec, Canada, which are substantially similar to the U.S. class action suits. Moreover, we have submitted relevant information and documentation to regulators in Australia, the European Union, Korea, New Zealand and Switzerland in connection with investigations initiated by such authorities into pricing practices of certain international air cargo carriers. These investigations and proceedings are continuing, and additional investigations and proceedings may be commenced and charges may be brought in these and other jurisdictions. Other parties may be added to these investigations and proceedings, and authorities may request additional information of the Company. If Polar LLC is unable to resolve the Antitrust Division investigation or is formally charged by the Antitrust Division as a result of this investigation, or if the Company were to incur an unfavorable outcome in connection with one or more of the related investigations or litigation, it could have a material adverse effect on the Company’s business, results of operations and financial condition.
 
USE OF PROCEEDS
 
We will not receive any of the proceeds from the sale of the shares by the selling stockholder.

We have never paid a dividend with respect to our common stock, nor do we anticipate paying a dividend in the foreseeable future. Moreover, certain of our financing arrangements contain financial covenants that could limit our ability to pay cash dividends.

DESCRIPTION OF CAPITAL STOCK
 
The following description summarizes important terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. This description is in all respects subject to and qualified in its entirety by reference to: (i) our certificate of incorporation and our amended and restated bylaws, which are filed as exhibits to our Current Reports on Form 8-K dated February 16, 2001 (filed with the SEC on February 21, 2001) and June 27, 2006 (filed with the SEC on July 3, 2006), respectively, (ii) the certificate of designation relating to each series of preferred stock, which will be filed with the SEC in connection with an offering of such series of preferred stock and (iii) the relevant portions of the Delaware General Corporation Law.
 
Our authorized capital stock consists of 50,000,000 shares of common stock, $0.01 par value, and 10,000,000 shares of preferred stock, $1.00 par value.
 
Common Stock
 
General.  As of March 31, 2009, there were 21,079,643 shares of common stock outstanding, excluding 886,438 shares held in treasury. There were 80 stockholders of record of our common stock on such date.
 
Voting Rights.  The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors, and they do not have 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. “Foreign Ownership Restrictions” below contains a description of certain restrictions on voting by stockholders who are not “U.S. citizens,” as defined by applicable laws and regulations.
 
Dividends.  Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive ratably those dividends, if any, as may be declared by the board of directors out of legally available funds.
 
Liquidation, Dissolution and Winding Up.  Upon our liquidation, dissolution or winding up, the holders of our 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, subject to the prior rights of any preferred stock then outstanding.
 
Preemptive Rights.  Holders of our common stock have no preemptive or conversion rights or other subscription rights and there are no redemption or sinking fund provisions applicable to our common stock.
 
Assessment.  All outstanding shares of our common stock are fully paid and nonassessable.
 
Preferred Stock
 
As of the date of this prospectus, 10,000,000 shares of undesignated preferred stock are authorized, none of which is outstanding. The board of directors has the authority, without further action by the stockholders, to issue from time to time the undesignated preferred stock in one or more series and to fix the number of shares, designations, preferences, powers, and relative, participating, optional, or other special rights and the qualifications or restrictions thereof. The preferences, powers, rights, and restrictions of different series of preferred stock may differ with respect to dividend rates, amounts payable on liquidation, voting rights, conversion rights, redemption provisions, sinking fund provisions, purchase funds, and other matters. The issuance of preferred stock could decrease the amount of earnings and assets available for distribution to holders of our common stock or adversely affect the rights and powers, including voting rights, of the holders of our common stock and may have the effect of delaying, deferring or preventing a change in control of our company.
 
Registration Rights
 
On February 13, 2007, we entered into a registration rights agreement (and an amendment thereto that was made on March 12, 2007) with our largest stockholders, HMC Atlas Air, L.L.C. and Harbinger Capital Partners Special Situation Fund, L.P. (together, the “Harbinger Entities”) as required by our Final Modified Second Amended Joint Plan of Reorganization. As of March 4, 2009, and based on information filed with the SEC, the


S-4


Table of Contents

Harbinger Entities beneficially owned 8,406,290 shares (or approximately 39.9%) of our outstanding common stock, substantially all of which are covered by the registration rights agreement.
 
On April 16, 2007, we filed a shelf registration statement registering the resale of approximately 7.9 million shares of our common stock that are covered by the registration rights agreement and naming the Harbinger Entities as the selling security holders. In addition, HMC Atlas Air, L.L.C. has the right to request that we file with the SEC up to two additional registration statements, registering the resale of registrable shares by the Harbinger Entities, subject to certain limitations, including certain “black-out” rights. We also granted the Harbinger Entities piggyback registration rights with respect to registration statements filed by us for public offerings. The Harbinger Entities have agreed to enter into customary lock-up agreements that may be requested by an underwriter in connection with any offerings of common stock by us.
 
We have agreed to pay for certain registration expenses incurred in connection with any registration statement filed in accordance with the terms of the registration rights agreement and to reimburse the Harbinger Entities for certain legal expenses. The Harbinger Entities may transfer their rights under the registration rights agreement to certain U.S. persons that acquire at least 5% of our issued and outstanding common stock, provided that HMC Atlas Air, L.L.C. will retain the right (i) to request that we file a registration statement with the SEC and (ii) to amend, terminate or waive any term set forth in the registration rights agreement.
 
Certain Anti-Takeover Provisions of our Certificate of Incorporation and Bylaws and Delaware Law
 
Some provisions of Delaware law and our certificate of incorporation and bylaws contain provisions that could make the following transactions more difficult: (i) acquisition of us by means of a tender offer; (ii) acquisition of us by means of a proxy contest or otherwise; or (iii) removal of our incumbent officers and directors. These provisions, summarized below, are intended to encourage persons seeking to acquire control of us to first negotiate with our board of directors. These provisions also serve to discourage hostile takeover practices and inadequate takeover bids.
 
Issuance of Preferred Stock.  As noted above, our board of directors, without stockholder approval, has the authority under our certificate of incorporation to issue preferred stock with rights superior to the rights of the holders of common stock. As a result, preferred stock could be issued quickly and easily, could adversely affect the rights of holders of common stock and could be issued with terms calculated to delay or prevent a change in control or make removal of management more difficult.
 
Stockholder Meetings.  A majority of our board of directors, the chairman of the board or the chief executive officer may call special meetings of stockholders.
 
Requirements for Advance Notification of Stockholder Nominations and Proposals.  Our bylaws contain advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or a committee thereof.
 
Delaware Anti-Takeover Statute.  We are subject to Section 203 of the Delaware General Corporation Law, which, subject to certain exceptions, prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a Delaware corporation for three years following the date these persons become interested stockholders, unless the business combination is approved in a prescribed manner. Generally, an “interested stockholder” is an entity or person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors.
 
The provisions of Delaware law and our certificate of incorporation and bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. Such provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make accomplishing transactions that stockholders may otherwise deem to be in their best interests more difficult.


S-5


Table of Contents

Other Measures that May Have an Anti-Taker Over Effect.  In addition to the provisions discussed above, the Board of Directors plans to consider other measures that could have the effect of discouraging acquisitions of substantial blocks of Company common stock or otherwise discouraging acquisition transactions, including the adoption of a shareholder rights plan.
 
Limitations on Liability and Indemnification of Officers and Directors
 
Our certificate of incorporation limits the liability of our directors to the fullest extent permitted by the Delaware General Corporation Law and our bylaws provide that we will indemnify our directors and officers to the fullest extent permitted by that law.
 
Transfer Agent and Registrar
 
The transfer agent and registrar for our common stock is BNY Mellon Shareowner Services.
 
NASDAQ Global Select Market
 
Our common stock is listed on The NASDAQ Global Select Market under the symbol “AAWW.”
 
Foreign Ownership Restrictions
 
Under federal law and DOT requirements, we must be owned and actually controlled by “citizens of the United States” as that term is defined in 49 U.S.C.§ 40102 (a)(15). In this regard, our President and at least two-thirds of our Board and officers must be U.S. citizens, at least 75% of our outstanding voting common stock must be owned and controlled, directly or indirectly, by persons who are “citizens of the United States”, and not more than 25% of our outstanding voting common stock may be owned and controlled, directly or indirectly, by persons who are not “citizens of the United States.” We believe that on the date of this prospectus supplement we are in compliance with these requirements.
 
Under our charter documents, consistent with U.S. law, there is a separate stock record, designated the “Foreign Stock Record,” for the registration of Voting Stock that is “Beneficially Owned” by persons who are not citizens of the United States. “Voting Stock” means all outstanding shares of our capital stock that we may issue from time to time which, by their terms, may vote. “Beneficially Owned” refers to owners of our securities who, directly or indirectly, have or share voting power and/or investment power.
 
At no time will ownership of our shares of common stock representing more than the “Maximum Percentage” be registered in the Foreign Stock Record. “Maximum Percentage,” which currently is 25%, refers to the maximum percentage of voting power of Voting Stock which may be voted by, or at the direction of, non-U.S. citizens without violating applicable statutory, regulatory or interpretative restrictions or adversely affecting Atlas’s or Polar’s operating certificates or authorities. If we find that the combined voting power of Voting Stock then registered in the Foreign Stock Record exceeds the Maximum Percentage, the registration of such shares will be removed from the Foreign Stock Record, in reverse chronological order based on the date of registration, and the voting rights of such Voting Stock removed from the Foreign Stock Record will be automatically suspended, sufficient to reduce the combined voting power of the shares so registered to an amount not in excess of the Maximum Percentage. It is the duty of each stockholder who is not a citizen of the United States to register his, her or its equity securities on our Foreign Stock Record.

The selling stockholder has agreed with the underwriters that, subject to certain limited exceptions, without the prior written consent of the underwriters, the selling stockholder will not directly or indirectly, during the period commencing on the date hereof and ending 60 days after the date hereof, sell, offer to sell, grant any option for the sale of, enter into any agreement to sell, or otherwise dispose of any shares of our common stock.
 
The underwriters, in their sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time with or without notice. When determining whether or not to release the common stock and other securities from lock-up agreements, the underwriters will consider, among other factors, the holder’s reasons for requesting the release, the number of shares or other securities for which the release is being requested and market conditions at the time.
 
In connection with the offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares from the selling stockholder in the offering. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will


S-8


Table of Contents

consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option granted to them. “Naked” short sales are any sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriters in the open market prior to the completion of the offering.
 
The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.
 
Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own account, may have the effect of preventing or retarding a decline in the market price of the common stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time. These transactions may be effected on The NASDAQ Global Select Market, in the over-the-counter market or otherwise.
 
Neither we nor the selling stockholder and the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In addition, neither we nor the selling stockholder and the underwriters make any representation that the underwriters will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

owned 7,939,690 shares (or approximately 37.4%) of our common stock, all of which are covered by the registration rights agreement.
 
Under the registration rights agreement, which was amended on March 12, 2007, we have agreed to file with the SEC, on the earlier of the date on which we become S-3 eligible or April 18, 2007, a shelf registration statement, registering the resale of shares of our common stock that are covered by the agreement and naming the Harbinger Entities as the selling security holders. In addition, at any time after we become eligible to file a registration statement on Form S-3, HMC Atlas Air will have the right to request that we file with the SEC up to two additional registration statements, registering the resale of registrable shares by the Harbinger Entities, subject to certain limitations, including certain “black-out” rights. We also granted the Harbinger Entities piggyback registration rights with respect to registration statements filed by us for public offerings. The Harbinger Entities have agreed to enter into customary lock-up agreements that may be requested by an underwriter in connection with any offerings of common stock by us.
 
We have agreed to pay for certain registration expenses incurred in connection with any registration statement filed in accordance with the terms of the registration rights agreement and to reimburse the Harbinger Entities for certain legal expenses. The Harbinger Entities may transfer their rights under the agreement to certain persons that acquire at least 5% of our issued and outstanding common stock, provided that HMC Atlas Air will retain the right (i) to request that we file a registration statement with the SEC and (ii) to amend, terminate or waive any term set forth in the agreement.
 
PLAN OF DISTRIBUTION
 
The common stock offered by this prospectus may be sold or distributed from time to time by the selling stockholders directly to one or more purchasers or through brokers, dealers, or underwriters who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders or the purchaser of the common stock, which discounts, concessions or commissions as to particular underwriters, brokers or agents may be in excess of those customary in the type of transactions involved.
 
The selling stockholders and any such broker-dealers or agents who participate in the distribution of the common stock may be deemed to be “underwriters.” As a result, any profits on the sale of the common stock by selling stockholders and any discounts, commissions or concessions received by any such broker-dealers or agents might be deemed to be underwriting discounts and commissions under the Securities Act. If the selling stockholders were deemed to be underwriters, the selling stockholders may be subject to certain statutory liabilities as underwriters under the Securities Act.
 
If the common stock is sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions.
 
The sale of the common stock offered by this prospectus may be effected in one or more transactions at:
 
  •  fixed prices;
 
  •  prevailing market prices at the time of sale;
 
  •  prices related to prevailing market prices;
 
  •  varying prices determined at the time of sale; or
 
  •  negotiated prices.
 
The sale of the common stock offered by this prospectus may be effected in one or more of the following methods:
 
  •  on any national securities exchange or quotation service on which the common stock may be listed or quoted at the time of the sale, including The NASDAQ Global Select Market;
 
•  transactions involving cross or block trades;
 
  •  in the over-the counter market;


4


Table of Contents

 
  •  through the distribution by any selling stockholder to its partners, members or shareholders;
 
  •  in other ways not involving market makers or established trading markets, including direct sales to purchasers or sales effected through agents;
 
  •  in privately negotiated transactions; or
 
  •  any combination of the foregoing.
 
In connection with the sales of the common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers. These broker-dealers may in turn engage in short sales of the common stock in the course of hedging their positions. The selling stockholders may also sell the common stock short and deliver the common stock to close out short positions, or loan or pledge the common stock to broker-dealers that in turn may sell the common stock.
 
In order to comply with the securities laws of certain states, if applicable, the shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the state or an exemption from the registration or qualification requirement is available and complied with.
 
We know of no existing arrangements between any selling stockholder, any other stockholder, broker, dealer, underwriter, or agent relating to the sale or distribution of the shares offered by this prospectus. To our knowledge, there are currently no plans, arrangements or understandings between any selling stockholders and any underwriter, broker-dealer or agent regarding the sale of the common stock by the selling stockholders. Selling stockholders may not sell any or all of the common stock offered by them pursuant to this prospectus. In addition, we cannot assure you that any such selling stockholders will not transfer, devise or gift the common stock by other means not described in this prospectus. There can be no assurance that any selling stockholders will sell any or all of the common stock pursuant to this prospectus. In addition, any common stock covered by this prospectus that qualifies for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus.
 
We will pay all of the expenses incident to the registration, offering, and sale of the shares to the public, other than commissions or discounts of underwriters, broker-dealers, or agents. We have also agreed to indemnify the selling stockholder and related persons against specified liabilities, including liabilities under the Securities Act.
 
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.
 
We have advised each of the selling stockholders that while it is engaged in a distribution of the shares included in this prospectus it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the selling stockholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the shares offered hereby this prospectus.
 
This offering will terminate on the date that all shares offered by this prospectus have been sold by the selling stockholders.
 
LEGAL MATTERS
 
The legality of our common stock offered hereby will be passed upon for us by Ropes & Gray LLP, Boston, Massachusetts.
