ITEM 1. SECURITY AND ISSUER. This Schedule 13D relates to the common stock, $.001 par value (the "Common Stock") of Lannett Company, Inc. (the "Issuer"), whose principal executive officers are located at 9000 State Road, Philadelphia, Pennsylvania 19136. ITEM 2. IDENTITY AND BACKGROUND. This Schedule 13D is filed by Perrigo Company, a Michigan corporation ("Perrigo"), whose principal executive offices are located at 515 Eastern Avenue, Allegan, Michigan 49010. During the last five years, neither Perrigo, nor, to the best knowledge of Perrigo, any director or executive officer of Perrigo or any person controlling Perrigo, has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding 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. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. On February 4, 2004, Perrigo entered into a Stock Purchase Option Agreement (the "Option Agreement") with William Farber and Audrey Farber (the "Farbers"), pursuant to which Perrigo acquired the option (the "Option") to purchase certain shares of Common Stock owned by the Farbers (as more fully described in Item 5 below) for an amount equal to $197,339,000, plus additional contingent consideration (the "Exercise Price"). The price of the Option was $180,000, and was funded from Perrigo's cash on hand. In the event that Perrigo exercises the Option, the price of the Option would be credited to the Exercise Price and the remainder of the funds required to pay the Exercise Price would be paid from cash and borrowings yet to be determined. ITEM 4. PURPOSE OF TRANSACTION. Perrigo has acquired the Option in contemplation of acquiring control of the Issuer. Because of the Farbers' large percentage ownership interest in the Issuer, if Perrigo exercises the Option, its acquisition of the Common Stock subject to the Option could lead to any of the actions or consequences noted in clauses (a) through (j) of Item 4 of Form 13D. Perrigo has represented to the Farbers that, if it exercises the Option, it will, within 90 days of acquiring the Common Stock subject to the Option, make a tender offer (to the extent permitted by law) or alternatively use its commercially reasonable efforts to enter into a merger agreement or other business combination with the Issuer for the remainder of the outstanding shares of Common Stock. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. Pursuant to the Option Agreement, Perrigo has the right to acquire 13,519,129 currently issued and outstanding shares of Common Stock as well as 37,500 shares of Common Stock issuable to Mr. Farber upon the exercise of certain in-the-money options owned by him (the "In-the-money Options"). In connection with Perrigo's exercise of the Option, Mr. Farber is required to exercise the In-the-money Options. Mr. Farber also currently holds certain other options (the "Other Options") to purchase 25,000 shares of Common Stock, which vest in installments beginning on October 14, 2004. Pursuant to the terms of the Other Options, however, the Other Options may accelerate and become exercisable immediately upon the grant of the Option and/or the exercise of the Option. Pursuant to the Option Agreement, Perrigo has the right to direct Mr. Farber to cause the Issuer to cancel the Other Options or, in the event that the Other Options are in fact exercisable, to direct Mr. Farber to exercise the Other Options and convey the issued shares of Common Stock to Perrigo. In the event that Perrigo exercises the Option and directs Mr. Farber to exercise and convey the stock subject to the Other Options, Perrigo will acquire 13,581,629 shares of Common Stock, which will constitute 67.5% of the total issued and outstanding Common Stock, based on 20,050,144 shares issued and outstanding as of October 23, 2003, as reported in the Issuer's Form 10-Q for the quarter ended September 30, 2003, plus 62,500 shares issuable upon the exercise of the In-the-money Options and the Other Options. Perrigo currently has no power to vote, to direct the vote, to dispose of, or to direct the disposition of any securities subject to the Option. In the event that Perrigo exercises the Option and directs Mr. Farber to exercise and convey the stock subject to the Other Options, it will have the sole power to vote and to dispose of all 13,581,629 shares of Common Stock subject to the Option. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF ISSUER. Except for the Option Agreement, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between Perrigo and any person with resect to any securities of the Issuer.
