Calculation of Registration Fee

(1)

Such securities, when aggregated with the 45,596,775 shares of FWONK previously sold under the Registration Statement by the selling stockholders and the 11,868,436 shares of FWONK which remain unsold thereunder, relate to (i) 54,660,897 shares of FWONK, issued to the selling stockholders, and (ii) 15,755,153 shares of FWONK, equaling the maximum number of shares of FWONK issuable upon the exchange of certain exchangeable notes issued to the selling stockholders plus shares of FWONK issuable in respect of accrued interest as of the date of this Post-Effective Amendment No. 1 to the Registration Statement. Upon the effectiveness of this Post-Effective Amendment No. 1 to the Registration Statement, the Registration Statement will relate to an aggregate of 24,819,275 shares of FWONK. The exchangeable notes provide for the payment of interest in kind. Accordingly, additional shares of FWONK that may become issuable upon exchange of exchangeable notes issued in lieu of cash interest payments under the exchangeable notes, if any, may be added to the shares of FWONK registered by the Registration Statement by the filing of a post-effective amendment by the registrant.

(2)

Estimated solely for purposes of calculating the registration fee pursuant to Rule 457(c) under the Securities Act based on the average high and low sale price per share of FWONK, as reported on the Nasdaq Global Select Market on September 14, 2017 with respect to the securities registered hereby. The filing fee with respect to the balance of the shares to which the Registration Statement will relate upon the effectiveness of this Post-Effective Amendment No. 1 to the Registration Statement was previously paid at the time of registration of such shares on the Registration Statement. The proposed maximum offering price per share of FWONK has been and will be determined from time to time by the selling stockholders in connection with, and at the time of, the sale by such selling stockholders of the shares of FWONK for sale by such selling stockholders.

This prospectus provides you with a general description of us and the securities offered under this prospectus.

        We will not receive any proceeds from the sale of shares of FWONK by the Selling Stockholders. The Selling Stockholders may sell their shares of FWONK through any means described below under the heading "Plan of Distribution."

        At the time that any particular offering of shares of FWONK is made, to the extent required by the Securities Act, the Selling Stockholders will provide a prospectus supplement that will contain specific information about the terms of that offering. A prospectus supplement may add to, update or change information in this prospectus.

Table of Contents

THE COMPANY

        The following summary highlights selected information included or incorporated by reference in this prospectus to help you understand our Company and shares of FWONK. For a more complete understanding of our Company and shares of FWONK, we encourage you to read this entire document and the information incorporated by reference herein, including the financial statements of the Company and the notes thereto. All references in this prospectus to the "Company," "Liberty Media," "we," "our" and "us" and words of similar effect refer to Liberty Media Corporation, and, unless the context otherwise requires, its consolidated subsidiaries.

Our Capital Structure

        Under our current restated certificate of incorporation (our "current charter"), our common stock is comprised of three tracking stocks, with each tracking stock divided into three series. Our tracking stocks, which are designated the Liberty SiriusXM common stock, the Liberty Braves common stock and the Liberty Formula One common stock, are intended to track and reflect the separate economic performance of the businesses, assets and liabilities attributed to the Liberty SiriusXM Group, the Braves Group and the Formula One Group, respectively. While each group has a separate collection of businesses, assets and liabilities attributed to it, none of these groups is a separate legal entity and therefore cannot own assets, issue securities or enter into legally binding agreements. Hence, holders of our Liberty SiriusXM common stock, Liberty Braves common stock and Liberty Formula One common stock have no direct claim to the relevant group's assets, and are not represented by a separate board of directors. Instead, holders of those stocks are stockholders of Liberty Media Corporation, with a single board of directors and subject to all of the risks and liabilities of Liberty Media as a whole.

        At a special meeting of stockholders of the Company held on January 17, 2017, our stockholders approved the adoption of an amendment and restatement of our then-existing charter (1) to change the name of the "Media Group" to the "Formula One Group," (2) to change the name of the "Liberty Media common stock" to the "Liberty Formula One common stock," (3) to reclassify each share of each series of our existing Liberty Media common stock into one share of the corresponding series of Liberty Formula One Common Stock solely to effect the name change and (4) to make certain conforming changes (the "group name change"). The current charter was filed with the Secretary of State of the State of Delaware on January 24, 2017 and gave effect to the group name change.

        The Liberty SiriusXM common stock tracks and reflects the separate economic performance of the businesses, assets and liabilities attributed to the Liberty SiriusXM Group, which includes, among other things, Liberty Media's approximate 68.55% interest in SIRIUS XM Holdings Inc. ("Sirius XM") as of June 30, 2017. The Liberty Braves common stock tracks and reflects the separate economic performance of the businesses, assets and liabilities attributed to the Braves Group, which includes, among other things, Liberty Media's wholly owned subsidiary Braves Holdings, LLC ("Braves Holdings"), which indirectly owns the Atlanta Braves Major League Baseball club (the "Braves"). The Liberty Formula One common stock, which includes FWONK, tracks and reflects the separate economic performance of the businesses, assets and liabilities attributed to the Formula One Group, which includes the remainder of Liberty Media's businesses, assets and liabilities not attributed to the Liberty SiriusXM Group or the Braves Group, including, among other things, Liberty Media's consolidated subsidiary Delta Topco Limited, the parent company of Formula 1 ("Delta Topco"), and Liberty Media's approximate 34% interest in Live Nation as of June 30, 2017 and 15.5% inter-group interest in the Braves Group as of June 30, 2017.

Our Business

        We own controlling and non-controlling interests in a broad range of media, communications and entertainment companies. Through our subsidiaries and affiliates, we principally operate in North

America. Our principal businesses and assets include our consolidated subsidiaries Sirius XM, Braves Holdings and Delta Topco, the parent company of Formula 1. In addition to the foregoing businesses, we hold ownership interests in Live Nation Entertainment, Inc. ("Live Nation") and, through Sirius XM, SIRIUS XM Canada, and we maintain investments in "available for sale" securities and related financial instruments in public companies such as Time Warner, Inc. ("Time Warner") and Viacom, Inc. ("Viacom"). Our business strategy and that of our subsidiaries and business affiliates includes selective acquisitions or other strategic initiatives focused on business expansion.

        Sirius XM.    Sirius XM provides a subscription based satellite radio service. Sirius XM transmits music, sports, entertainment, comedy, talk, news, traffic and weather channels, as well as infotainment services in the United States on a subscription fee basis through its two proprietary satellite radio systems—the Sirius system and the XM system. Subscribers can also receive their music and other channels, plus features such as SiriusXM On Demand and MySXM, over Sirius XM's Internet radio service, including through applications for mobile devices, home devices and other consumer electronic equipment. Sirius XM is also a leader in providing connected vehicle services. Sirius XM's connected vehicle services are designed to enhance the safety, security and driving experience for vehicle operators while providing marketing and operational benefits to automakers and their dealers. Sirius XM has agreements with every major automaker to offer satellite radios in their vehicles from which Sirius XM acquires the majority of its subscribers. It also acquires subscribers through marketing to owners and lessees of previously owned vehicles that include factory-installed satellite radios that are not currently subscribing to Sirius XM services. Additionally, Sirius XM distributes its radios through retailer stores nationwide and through its website. Satellite radio services are also offered to customers of certain rental car companies.

        Our consolidated subsidiary Sirius XM is attributed to our Liberty SiriusXM Group.

        Braves Holdings.    Braves Holdings is our wholly owned subsidiary that indirectly owns and operates the Braves and five minor league baseball clubs (the Gwinnett Braves, the Mississippi Braves, the Rome Braves, the Danville Braves and the GCL Braves). Braves Holdings also operates a baseball academy in the Dominican Republic and leases a baseball facility from a third party in connection with its academy. Braves Holdings had exclusive operating rights to Turner Field, the home stadium of the Atlanta Braves, until December 31, 2016 pursuant to an Operating Agreement with the Atlanta Fulton County Recreation Authority. Effective for the 2017 season, the Braves relocated into a new ballpark located in Cobb County, a suburb of Atlanta. The facility is leased from Cobb County, Cobb-Marietta Coliseum and Exhibit Hall Authority and will offer a range of activities and eateries for fans. Braves Holdings and its affiliates participated in the construction of the new stadium and are participating in the construction of an adjacent mixed-use development project, which we refer to as the Development Project.

        Our wholly owned subsidiary Braves Holdings is attributed to our Braves Group.

        Formula 1.    As discussed further below under "—Description of the Formula 1 Acquisition," in January 2017, we acquired 100% of the fully diluted equity interests of Delta Topco, the parent company of the group of companies that exploit exclusive commercial rights pertaining to the FIA Formula One World Championship® (the "World Championship") (such companies, together with Delta Topco, "Formula 1"), other than a nominal number of equity securities held by the Teams (as defined below). The World Championship is an annual, approximately nine-month long, motor race-based competition in which teams (the "Teams") compete for the Constructors' Championship and drivers compete for the Drivers' Championship. The World Championship is a global series with a varying number of events ("Events") taking place in different countries around the world each season. During 2016, 21 Events took place in 21 countries across Europe, Asia-Pacific, the Middle East and North and South America. Formula 1 is followed by hundreds of millions of television viewers in over 200 territories, and Formula 1's largest Events have hosted live audiences of up to 350,000 on race

Of the shares we beneficially own, 464,323 have been pledged as collateral to secure obligations of certain subsidiaries of Braves Holdings pursuant to credit facilities entered into by those subsidiaries to fund certain costs of the Development Project.

        Our shares of Time Warner common stock are attributed to our Formula One Group.

Description of the Formula 1 Acquisition

        The following describes certain material terms of, and documents and agreements related to, the Formula 1 Acquisition (as defined below). This summary is not complete and it is qualified in its entirety by reference to the Second SPA (as defined below), which is incorporated by reference as Exhibit 10.57 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, and the documents that are incorporated herein by reference.

        On September 7, 2016, Liberty Media entered into two definitive stock purchase agreements relating to the purchase by our indirect wholly-owned subsidiary, Liberty GR Cayman Acquisition Company, a company registered in the Cayman Islands (the "Buyer"), of 100% of the fully diluted equity interests of Delta Topco, other than a nominal number of equity securities held by the Teams (the "Formula 1 Acquisition"). For the purposes of this prospectus, references to "F1 Shares" include outstanding ordinary shares in Delta Topco, and references to "F1 Loan Notes" include the 10% unsecured loan notes due November 24, 2060, issued by Delta Topco pursuant to an unsecured loan note instrument dated November 24, 2006, as amended and restated from time to time.

        On September 7, 2016, Liberty Media, the Buyer, Formula 1 and certain selling shareholders of Formula 1 (the "Initial Sellers") entered into the first stock purchase agreement (the "First SPA"), pursuant to which the Buyer purchased 18.7% of the fully diluted F1 Shares and F1 Loan Notes from the Initial Sellers for an aggregate purchase price of approximately $746 million (the F1 Shares and the F1 Loan Notes purchased pursuant to the First SPA hereinafter referred to as the "initial securities"). The transactions contemplated by the First SPA were consummated on September 7, 2016, immediately following its execution and delivery (the "First Closing").

        Pursuant to the First SPA, on October 27, 2016, the Buyer purchased additional F1 Shares and F1 Loan Notes (the "additional securities") from certain of the Initial Sellers to increase its ownership percentage in Formula 1 to approximately 19.1% of the fully diluted F1 Shares and F1 Loan Notes outstanding on the closing of the purchase of the additional securities (the "Additional Closing"). The aggregate purchase price paid at the Additional Closing was approximately $13 million.

Table of Contents

        Also on September 7, 2016, Liberty Media, the Buyer, Formula 1 and the Initial Sellers entered into the second stock purchase agreement (the "Second SPA"). Pursuant to the Second SPA, the other shareholders of Formula 1 (together with the Initial Sellers, the "Selling Stockholders") (i) entered into a deed of adherence to the Second SPA before the closing of the Second SPA (the "Second Closing") or (ii) became bound by the terms of the Second SPA pursuant to a drag along notice issued by Formula 1 pursuant to Formula 1's Articles of Association. Pursuant to the Second SPA:

•

the purchase and sale of the initial securities and the additional securities consummated pursuant to the First SPA was unwound in full immediately prior to the Second Closing;



•

the amount of cash paid to the Initial Sellers at the First Closing and the Additional Closing was credited against the amount of cash payable at the Second Closing;



•

immediately following the unwind of the First Closing and the Additional Closing, and prior to the Second Closing, a substantial portion of the issued and outstanding F1 Loan Notes were converted into additional F1 Shares and the remaining portion of the issued and outstanding F1 Loan Notes were converted into subordinated exchangeable debt instruments (the "Exchangeable Notes") issued by Delta Topco in an aggregate principal amount of approximately $351 million through an amendment and restatement to the existing loan note instrument constituting the F1 Loan Notes; and



•

the Buyer acquired from the Selling Stockholders 100% of the fully diluted F1 Shares (other than a nominal number of equity securities held by the Teams).

        Pursuant to the Second SPA, following the request of a nominee appointed by the Selling Stockholders (the "Sellers' Representative"), on December 13, 2016, Liberty Media entered into investment agreements (the "Investment Agreements") with certain third party investors pursuant to which such third party investors agreed to purchase approximately 62 million shares of FWONK at a price of $25.00 per share, for an aggregate purchase price of $1.55 billion. The transactions contemplated by the Investment Agreements were consummated concurrently with the Second Closing. The net proceeds received under the Investment Agreements were used to fund a portion of the cash consideration payable to the Selling Stockholders at the Second Closing, and increased such cash consideration by an amount equal to the proceeds received by Liberty Media pursuant to the Investment Agreements (less selling expenses) and decreased the number of shares of FWONK otherwise issuable to the Selling Stockholders by the number of shares of FWONK actually sold pursuant to the Investment Agreements. Liberty Media did not retain any proceeds from the sale of shares of FWONK to the third party investors pursuant to the Investment Agreements.

        At the Second Closing, pursuant to a side letter entered into with the Sellers' Representative under the Second SPA, we purchased approximately 19 million shares of FWONK at the $21.26 reference price, thereby increasing the cash consideration payable to the Selling Stockholders by $400 million. A portion of the net proceeds from Liberty Media's private offering of $450 million aggregate principal amount of its 1.0% cash convertible senior notes due 2023, which closed on January 23, 2017, was used to fund the increase in the cash consideration to the Selling Stockholders. These shares of FWONK were reserved by Liberty Media in treasury for possible issuance to the Teams but have since been retired. The aggregate number of shares of FWONK issued at the Second Closing did not change as a result of this transaction. Only the allocation of the approximately 137 million shares of FWONK changed as follows: approximately 56 million to the Selling Stockholders, approximately 62 million to the third party investors and approximately 19 million into treasury (all of which approximately 19 million shares have subsequently been retired).

Table of Contents

        The Second Closing was completed on January 23, 2017. The aggregate purchase price paid to the Selling Stockholders under the Second SPA was approximately $4.4 billion (calculated at the time of transaction announcement, assuming a valuation for the shares of FWONK of $21.26), consisting of:

•

$3.05 billion in cash (including the cash paid to the Initial Sellers at the First Closing and the Additional Closing);



•

approximately $351 million in principal amount of the Exchangeable Notes (which consisted of outstanding F1 Loan Notes that were converted upon the Second Closing); and



•

approximately 56 million newly issued shares of FWONK.

SELLING STOCKHOLDERS

        This prospectus relates to the offer and sale from time to time by the Selling Stockholders of up to 24,819,268 shares of FWONK, which are comprised of (i) shares of FWONK issued to the Selling Stockholders at the Second Closing and which remain unsold as of the date of this prospectus and (ii) the maximum number of shares of FWONK issuable upon the exchange of the Exchangeable Notes issued to the Selling Stockholders at the Second Closing. The shares of FWONK offered pursuant to this prospectus were issued to the Selling Stockholders in transactions that were exempt from the registration requirements of the Securities Act. See "The Company—Description of the Formula 1 Acquisition" for additional information regarding the Formula 1 Acquisition.

        At the Second Closing, we entered into a shareholders agreement with the Selling Stockholders. Pursuant to the shareholders agreement, we agreed to file the registration statement of which this prospectus forms a part covering the resale of the shares of FWONK issued to the Selling Stockholders at the Second Closing or issuable upon the exchange of the Exchangeable Notes issued to the Selling Stockholders at the Second Closing. See "—The Shareholders Agreement" for additional information regarding the shareholders agreement.

        The Selling Stockholders may offer and sell, pursuant to a prospectus supplement, any or all of such shares of FWONK beneficially owned by them at the time of such offer and sale and offered hereby in accordance with one or more of the methods of distribution described under the caption "Plan of Distribution."

        Information regarding the Selling Stockholders, the beneficial ownership of shares of FWONK by the Selling Stockholders, the number of shares of FWONK being offered by Selling Stockholders, the number of shares of FWONK and the percentage of the class to be beneficially owned by Selling Stockholders after the applicable offering and whether any of the Selling Stockholders has held any position or office with, has been employed by or otherwise has had a material relationship with us during the prior three years, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment or in filings we make with the Commission under the Exchange Act, which are incorporated by reference.

The Formula 1 Acquisition

        The shares of FWONK to be offered and resold by the Selling Stockholders pursuant to this prospectus are comprised of (i) 9,064,122 of the 54,660,897 shares of FWONK issued to the Selling Stockholders at the Second Closing (the "Stock Consideration") which remain unsold at the date of this prospectus and (ii) 15,755,153 shares of FWONK, equaling the maximum number of shares of FWONK issuable upon the exchange of the Exchangeable Notes issued to the Selling Stockholders at the Second Closing plus shares of FWONK issuable upon exchange of additional exchangeable notes issued by us in respect of accrued interest as of the date of this prospectus. The Stock Consideration and the Exchangeable Notes constituted a portion of the purchase price paid to the Selling Stockholders under the Second SPA in exchange for 100% of the fully-diluted equity interests in Delta Topco (other than a nominal number of equity securities held by the Teams).

        See "The Company—Description of the Formula 1 Acquisition" for additional information.

The Exchangeable Notes

        Pursuant to the Second SPA, effective at the Second Closing, Formula 1 amended and restated the instrument governing the F1 Loan Notes such that it would reflect the rights and preferences applicable to the Exchangeable Notes. At the Second Closing, approximately $351 million in principal amount of the Exchangeable Notes were issued to the Selling Stockholders (in their respective capacities as holders of Exchangeable Notes, the "Noteholders").

11

Table of Contents

        The Exchangeable Notes will be exchangeable for newly issued shares of FWONK in the following circumstances:

•

Noteholder Optional Exchange.  Noteholders have the right, at any time, to require Formula 1 (which is now an indirect subsidiary of Liberty Media), to exchange any or all of the Exchangeable Notes held by such Noteholder for a number of fully paid shares of FWONK equal to the quotient of (i) the principal amount of the Exchangeable Notes to be so exchanged, plus accrued and unpaid interest thereon, and (ii) 105% of the $21.26 reference price, which is the assumed valuation of shares of FWONK utilized in the Formula 1 Acquisition (subject to adjustment for certain events). Alternatively, upon receipt of a request for a Noteholder optional exchange, Formula 1 has the right to redeem the Exchangeable Notes for an amount in cash.



•

Mandatory Exchange.  At any time when the total principal amount of the Exchangeable Notes (including PIK notes) outstanding and owned by a Noteholder or its affiliates is less than the total principal amount of Exchangeable Notes first issued to such Noteholder, Formula 1 has the right to require the Noteholder to exchange any or all such Exchangeable Notes for a number of fully paid shares of FWONK equal to (i) the principal amount of the Exchangeable Notes to be so exchanged, plus all accrued and unpaid interest thereon, divided by (ii) the volume weighted average trading price of shares of FWONK over the five consecutive trading days ending on the trading day immediately prior to the notification of the mandatory exchange. Alternatively, Formula 1 may elect to redeem any or all of such Exchangeable Notes for an amount in cash equal to the principal amount of the Exchangeable Notes to be redeemed plus accrued and unpaid interest thereon.



•

Transfer Exchange.  Formula 1 has the option to redeem Exchangeable Notes that a Noteholder proposes to transfer to a person (other than a permitted transferee) at a price, payable in cash, equal to the product of (i) the principal amount of the Exchangeable Notes proposed to be transferred, plus all accrued and unpaid interest thereon, divided by the exchange price, and (ii) the volume weighted average trading price of shares of FWONK over the five consecutive trading days ending on the trading day immediately prior to the delivery of the notice of transfer. If Formula 1 does not timely exercise its right to effect a transfer purchase, the Exchangeable Notes to be transferred shall be automatically exchanged prior to such transfer for a number of shares of FWONK equal to the quotient of (i) the principal amount of the Exchangeable Notes proposed to be transferred, plus all accrued and unpaid interest thereon, and (ii) 105% of the $21.26 reference price (subject to adjustment for certain events).

        The foregoing description describes certain material terms of the Exchangeable Notes. This summary is not complete and it is qualified in its entirety by reference to the form of Delta Topco Limited Exchangeable Redeemable Loan Note Instrument, which is incorporated by reference as Exhibit 10.60 to our Annual Report on Form 10-K for the year ended December 31, 2016.

The Shareholders Agreement

        At the Second Closing, we entered into a shareholders agreement (the "shareholders agreement") with the Selling Stockholders. Pursuant to the shareholders agreement, we agreed to file, as soon as reasonably practicable on or following the date of the Second Closing, a shelf registration statement on Form S-3 with the Commission with respect to the registration under the Securities Act of shares of FWONK comprised of (i) all shares of FWONK issued to the Selling Stockholders at the Second Closing and (ii) approximately 15.7 million shares of FWONK, equaling the maximum number of shares of FWONK issuable upon the exchange of the Exchangeable Notes issued to the Selling Stockholders at the Second Closing (the "Transaction Shelf Registration Statement"). Additionally, under the shareholders agreement, any Selling Stockholder party thereto is entitled to five demand registrations and unlimited piggyback registration rights to sell all or a portion of the shares held by

12

Table of Contents

such Selling Stockholder that were issued at the Second Closing or issued in exchange for Exchangeable Notes and that have not been transferred ("registrable securities") pursuant to a registration statement filed by Liberty Media. The aggregate market value of registrable securities that are the subject of a demand registration request, as measured by the market price on the date of such demand registration request, must be at least $100 million and Liberty Media will not be obligated to effect more than one demand registration statement in any 90 day calendar period. If a demand registration is an underwritten public offering (subject to certain exceptions), the Shareholder Representative (as defined in the shareholders agreement) will select the managing underwriters and counsel for such offering, subject to the approval of Liberty Media (such approval not to be unreasonably withheld).

        The shareholders agreement includes provisions regarding our and the Selling Stockholders' mutual indemnification rights and obligations relating to the registration of the Selling Stockholders' shares of FWONK. Under the shareholders agreement, we agreed to indemnify and hold harmless each Selling Stockholder named in a prospectus supplement to the fullest extent lawful against damages, directly or indirectly caused by, relating to, arising out of, based upon or in connection with any untrue statement of material fact (or alleged untrue statement of material fact) in this prospectus, or any amendment or supplement hereto, or any omission or alleged omission to state a material fact required to be stated in this prospectus, or any amendment or supplement hereto, necessary to make the statements herein, in light of the circumstances under which they were made, not misleading. Our obligations to indemnify the Selling Stockholders will not extend to any damages to a Selling Stockholder directly caused by a statement or omission in this prospectus, or any amendment or supplement hereto, made in reliance upon and in conformity with written information furnished to Liberty Media by the Selling Stockholder or on such Selling Stockholder's behalf, in either case expressly for use herein, or in any amendment or supplement hereto, relating to the Selling Stockholder. Similarly, under the shareholders agreement, the Selling Stockholders agreed to indemnify us (and our officers, directors, controlling affiliates and affiliates of the foregoing) against any and all damages to the extent directly caused by any untrue statement of material fact (or alleged untrue statement of material fact) or any omission or alleged omission to the extent such untrue statement or omission was made in reliance upon and in conformity with written information furnished to Liberty Media by the Selling Stockholder or on such Selling Stockholder's behalf, in either case expressly for use in this prospectus, or any amendment or supplement hereto. Each Selling Stockholder's obligation to indemnify us is limited to the net proceeds received by such Selling Stockholder from the sale of registrable securities related to the matter in which damages are sought.

        The foregoing description describes certain material terms of the shareholders agreement. This summary is not complete and it is qualified in its entirety by reference to the form of Shareholders Agreement, which is incorporated by reference as Exhibit 10.59 to our Annual Report on Form 10-K for the year ended December 31, 2016.

Table of Contents

        The Selling Stockholders and any underwriters, broker-dealers or agents that participate in the sale of their respective shares of FWONK may be deemed by the Commission to be "underwriters" within the meaning of Section 2(a)(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may therefore be underwriting discounts and commissions under the Securities Act.

        In order to comply with the securities laws of some states, if applicable, shares of FWONK may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states shares of FWONK 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.

        Underwriters or agents could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an at-the-market offering as defined in Rule 415 promulgated under the Securities Act, which includes sales made directly on or through the Nasdaq Global Select Market, the existing trading market for shares of FWONK, or sales made to or through a market maker other than on an exchange.

        We will bear the costs relating to the registration and sale of the shares of FWONK offered by this prospectus, other than any underwriting discounts and commissions and transfer taxes applicable to sales by the Selling Stockholders of their respective shares of FWONK, if any. We have agreed to indemnify the Selling Stockholders against certain damages, including liabilities with respect to any violation by us of the Securities Act, the Exchange Act and state securities laws applicable to us and relating to the registration of the shares of FWONK offered by this prospectus that have not directly resulted from written information about the Selling Stockholders furnished by or on behalf of the Selling Stockholders to us expressly for use in connection with such registration.

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.    Other Expenses Of Issuance And Registration.

        The following table sets forth the costs and expenses payable by the Registrant in connection with the issuance and distribution of the shares of FWONK being registered hereunder. All amounts are estimates except the registration fee.

Item 15.    Indemnification Of Directors And Officers.

        Section 145 of the Delaware General Corporation Law ("DGCL") provides, generally, that a corporation shall have the power 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 (except actions 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 the corporation against all expenses, 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 his or her conduct was unlawful. A corporation may similarly indemnify such person for expenses actually and reasonably incurred by such person in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided that a court shall have determined, upon application, 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 such court shall deem proper.

        Section 102(b)(7) of the DGCL provides, generally, that the certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision may not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under section 174 of Title 8 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. No such provision may eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision became effective.

        Article V, Section E of the Restated Certificate of Incorporation (the "Charter") of the Registrant provides as follows:

        1.    Limitation On Liability.    To the fullest extent permitted by the DGCL as the same exists or may hereafter be amended, a director of the Registrant will not be liable to the Registrant or any of its stockholders for monetary damages for breach of fiduciary duty as a director. Any repeal or

II-1

Table of Contents

modification of this paragraph 1 will be prospective only and will not adversely affect any limitation, right or protection of a director of the Registrant existing at the time of such repeal or modification.

        2.    Indemnification.    

        (a)    Right to Indemnification.    The Registrant will indemnify, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "proceeding") by reason of the fact that he, or a person for whom he is the legal representative, is or was a director or officer of the Registrant or is or was serving at the request of the Registrant as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys' fees) incurred by such person. Such right of indemnification will inure whether or not the claim asserted is based on matters which antedate the adoption of Article V, Section E of the Charter. The Registrant will be required to indemnify or make advances to a person in connection with a proceeding (or part thereof) initiated by such person only if the proceeding (or part thereof) was authorized by the board of directors of the Registrant.

        (b)    Prepayment of Expenses.    The Registrant will pay the expenses (including attorneys' fees) incurred by a director or officer in defending any proceeding in advance of its final disposition; provided, however, that the payment of expenses incurred by a director or officer in advance of the final disposition of the proceeding will be made only upon receipt of an undertaking by the director or officer to repay all amounts advanced if it should be ultimately determined that the director or officer is not entitled to be indemnified under this paragraph or otherwise.

        (c)    Claims.    If a claim for indemnification or payment of expenses under this paragraph is not paid in full within 60 days after a written claim therefor has been received by the Registrant, the claimant may file suit to recover the unpaid amount of such claim and, if successful, will be entitled to be paid the expense (including attorney's fees) of prosecuting such claim to the fullest extent permitted by Delaware law. In any such action the Registrant will have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under applicable law.

        (d)    Non-Exclusivity of Rights.    The rights conferred on any person by Article V, Section E of the Charter will not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of the Charter, the bylaws of the Registrant, agreement, vote of stockholders or resolution of disinterested directors or otherwise.

        (e)    Other Indemnification.    The Registrant's obligation, if any, to indemnify any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or nonprofit entity shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, enterprise or nonprofit entity.

        3.    Amendment or Repeal.    Any amendment, modification or repeal of the foregoing provisions of Article V, Section E of the Charter will not adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.

Item 17.    Undertakings.

        (a)   We hereby undertake:

        (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 this 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 this 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 Commission pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration 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 this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (i), (ii) and (iii) above 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 Securities and Exchange Commission by the registrant pursuant to Section 13

Table of Contents

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.

        (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 purposes of determining any liability under the Securities Act to any purchaser

          (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 of 1933 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 the 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; and

        (5)   That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

          (i)  Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

         (ii)  Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

        (iii)  The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

        (iv)  Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

II-4

Table of Contents

        (b)   We hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report, pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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 Securities and Exchange Commission 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.
