SECURITY AND ISSUER. This statement on Schedule 13D (this "Statement") relates to the common stock, $0.01 par value ("Common Stock") of Denny's Corporation, a Delaware corporation (the "Issuer"). The principal executive office of the Issuer is 203 East Main Street, Spartanburg, South Carolina 29319-0001. ITEM 2. IDENTITY AND BACKGROUND. (a), (b) and (c) This Statement is being filed by (i) Jason Ader, an individual; (ii) Hayground Cove Asset Management LLC, a Delaware limited liability company ("HCAM"); (iii) Hayground Cove Fund Management LLC, a Delaware limited liability company ("HCFM"); and (iv) Hayground Cove Associates LP, a Delaware limited partnership ("HCA" and, together with Jason Ader, HCAM and HCFM, the "Reporting Persons"). Mr. Ader is the sole member of HCAM, which in turn is the managing member of HCFM. In addition, HCFM serves as general partner of (i) certain Delaware limited partnership funds and (ii) HCA, an investment manager that provides investment and advisory services to certain offshore entities and individually managed accounts (the limited partnership funds, offshore entities and managed accounts collectively, the "Client Funds"). None of the Client Funds is deemed to be a reporting person. The principal business of each of the Reporting Persons is providing investment management and advisory services to the Client Funds. The principal business address and principal office address of each of the Reporting Persons is 1370 6th Avenue, New York, New York 10019. (d) and (e) During the past five years, none of the Reporting Persons has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. (f) Mr. Ader is a United States citizen. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Each of the Client Funds has purchased in the aggregate the shares of Common Stock reported in Item 5, which shares are indirectly beneficially owned by the Reporting Persons. The aggregate amount of funds required by the Client Funds to acquire the shares of Common Stock was $25,534,742, net of commissions. The funds were provided by working capital of each of the Client Funds. ITEM 4. PURPOSE OF TRANSACTION. The Reporting Persons have effected the purchase of the shares of Common Stock by the Client Funds reported in Item 5 in open market transactions because, in their opinion, such shares are undervalued by the market at the present time. PAGE 7 OF 10 PAGES The Reporting Persons believe that the addition of the shares of Common Stock of the Issuer in the accounts of the Client Funds is a strong positive development. In particular, the Reporting Persons are supportive of the efforts, business initiatives and management of the Issuer. The Reporting Persons have effected the acquisition of the shares of Common Stock by the Client Funds reported in Item 5 for investment purposes only. However, the Reporting Persons intend to closely monitor the Issuer's performance and may modify their plans in the future. Although the Reporting Persons do not have any current plans other than monitoring the Common Stock of the Issuer, the Reporting Persons may in the future exercise, or cause to be exercised, any and all of their respective rights (or the rights of any of the Client Funds) as stockholders of the Issuer in a manner consistent with their equity interests (or the equity interests of any of the Client Funds). More specifically, depending on their evaluation of various factors, including the investment potential of shares of Common Stock, the Issuer's business prospects and financial position, other developments concerning the Issuer, the price level and availability of the Common Stock, available opportunities to acquire or dispose of shares of Common Stock, realize trading profits or minimize trading losses, conditions in the securities markets and general economic and industry conditions, reinvestment opportunities and other factors deemed relevant, the Reporting Persons may take, or cause to be taken, such actions with respect to their indirect holdings in the Issuer as they deem appropriate in light of circumstances existing from time to time. Such actions may include the purchase of additional shares of Common Stock by some or all of the Client Funds in the open market, through privately negotiated transactions with third parties or otherwise, or the sale at any time by some or all of the Client Funds, in the open market, through privately negotiated transactions with third parties or otherwise, of all or a portion of the shares now owned or hereafter acquired by any of the Client Funds. As of the date of this Statement, except as set forth above, none of the Reporting Persons has any present plan or intention that would result in or relate to any of the actions described in this Item 4. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) In the aggregate, the Client Funds are the direct beneficial owners of 5,612,200 shares of Common Stock currently indirectly owned by the Reporting Persons, or approximately 6.08% of outstanding shares of Common Stock of the Issuer, based upon 92,370,470 shares of Common Stock outstanding as of August 1, 2006, as reported by the Issuer in its Quarterly Report on Form 10-Q for the quarter ended June 28, 2006. None of the Client Funds own individually in excess of five percent of the outstanding shares of Common Stock. By virtue of the relationships described in Item 2 of this Statement and this Item 5, each of the Reporting Persons (other than HCA) may be deemed to share indirect beneficial ownership of all of the shares of Common Stock directly beneficially owned by the Client Funds. HCA may be deemed to share indirect beneficial ownership of the shares of Common Stock as expressly set forth below.

In addition, HCFM is general partner of HCA, which in turn serves as investment manager pursuant to certain Investment Management Agreements entered into between HCA and certain individual Client Funds. In this capacity, HCA exercises the power to vote (or to direct the vote) and to dispose (or to direct the disposition of) (i) 2,622,907 shares (or 2.84% of outstanding shares) of Common Stock held directly by Hayground Cove Overseas Partners Ltd., a Cayman Islands exempted limited company; (ii) 371,208 shares (or 0.40% of outstanding shares) of Common Stock held directly by Hayground Cove Turbo Fund Ltd., a Cayman Islands exempted limited company; (iii) 49,925 shares (or 0.05% of outstanding shares) of Common Stock held directly by Hayground Cove Equity Market Neutral Fund Ltd., a Cayman Islands exempted limited company; and (iv) certain independent managed accounts, each of which directly owns 624,025 shares (or 0.68% of outstanding shares) of Common Stock, 363,359 shares (or 0.39% of outstanding shares) of Common Stock, 576,143 shares (or 0.62% of outstanding shares) of Common Stock and 74,022 shares (or 0.08% of outstanding shares) of Common Stock, respectively.
