CUSIP No. 343389-10-2 13D Page 4 of 7 Pages Introduction. William R. Ziegler, the reporting person named below (the "Reporting Person"), was a party to a joint Schedule 13D with Marlin Investors, L.L.C., a Delaware limited liability company ("Marlin"), with respect to the securities of the issuer, because as the sole managing member of Marlin, the Reporting Person may be deemed to beneficially own all of the securities of the issuer owned of record by Marlin. As previously disclosed in an Amendment No. 2 to Schedule 13D jointly filed by the Reporting Person and Marlin (the "Second Amendment") with the Securities and Exchange Commission (the "Commission") on November 29, 2000, effective as of the close of business on November 20, 2000, after giving effect to the pro rata distribution of an aggregate of 9,333,334 shares of Common Stock by Marlin to its members, Marlin ceased to be the beneficial owner of five (5%) percent or more of the issued and outstanding shares of Common Stock, and therefore ceased to be a reporting person, as such term is defined in the regulations promulgated by the Commission pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Reporting Person is filing this Amendment No. 3 to Schedule 13D (the "Third Amendment"; and together with the Initial Statement, the First Amendment, and the Second Amendment, the "Schedule 13D") to disclose: (i) his acquisition of shares of Common Stock upon the exercise in full of all Preferred Stock Warrants owned by him; (ii) the change in domicile of the issuer from Alberta, Canada to Delaware, USA, inclusive of a 120:1 reverse stock split transaction; (iii) his conversion of all shares of Preferred Stock owned by him into shares of Common Stock; and (iv) that effective as of the close of business on October 31, 2001, after giving effect to the consummation of a series of transactions involving the issuer, inclusive of various exercises of all outstanding Preferred Stock Warrants by the holders thereof (including the Reporting Person), the change of domicile and reverse stock split transaction, the conversion of all outstanding shares of Preferred Stock by the holders thereof (including the Reporting Person), and the issuance of new shares of the issuer in connection with its merger with Chemical & Equipment Specialities, Inc. ("CESI"), as more fully described elsewhere in this Third Amendment, the Reporting Person ceased to be the beneficial owner of five (5%) percent or more of the issued and outstanding shares of Common Stock, and therefore ceased to be a reporting person, as such term is defined in the regulations promulgated by the Commission pursuant to the Exchange Act. Capitalized terms used in this Third Amendment without definition shall have the respective meanings ascribed to them in the First Amendment (which, in accordance with Rule 101 (a) (2) (ii) of Regulation S-T promulgated by the Commission, was a restatement of the entire text of the Initial Statement) or the Second Amendment, as the case may be. William R. Ziegler, the reporting person named below (the "Reporting Person"), was a party to a joint Schedule 13D with Marlin Investors, L.L.C., a Delaware limited liability company ("Marlin"), with respect to the securities of the issuer, because as the sole managing member of Marlin, the Reporting Person may be deemed to beneficially own all of the securities of the issuer owned of record by Marlin. CUSIP No. 343389-10-2 13D Page 5 of 7 Pages ________________________________________________________________________________ Item 1. Security and Issuer. This statement relates to the common stock, par value $0.0001 per share (the "Common Stock") of Flotek Industries Inc., a Delaware corporation (the "Company"), and the successor issuer to Flotek Industries Inc., a corporation organized under the laws of the Province of Alberta, Canada (the "Company"). The address of the principal executive offices of the Company is 7030 Empire Central Drive, Houston, Texas 77040. ________________________________________________________________________________ Item 2. Identity and Background. The Reporting Person is a natural person and has a business address of 230 Park Avenue, 11th Floor, New York, New York 10169. The present principal occupation or employment of the Reporting Person is as counsel to Satterlee Stephens Burke & Burke LLP, a law firm with its principal place of business located at 230 Park Avenue, 11th Floor, New York, New York 10169. The Reporting Person is a United States citizen. During the last five years, the Reporting Person has not been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). During the last five years, the Reporting Person was not 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. No change, except to disclose that the source and amount of funds for the exercise in full by the Reporting Person of all Preferred Stock Warrants owned by him was personal funds in the aggregate amount of $105,750 (approximately $0.03 per share for 3,525,034 shares of Common Stock acquired). ________________________________________________________________________________ Item 4. Purpose of Transaction. No change, except for the disclosure of the following transactions that took place since the filing of the Second Amendment: On August 29, 2001, the Reporting Person acquired an aggregate of 3,525,034 shares of Common Stock upon the exercise of all Preferred Stock Warrants owned by him. On October 30, 2001, the Company changed its domicile from Alberta, Canada to Delaware, USA, and effected a 120:1 reverse stock split transaction. As part of such reverse stock split transaction, the number of shares of Common Stock issuable upon exercise or conversion (as the case may be) of all outstanding derivative securities (inclusive of shares of Preferred Stock and stock options owned by the Reporting Person), and the exercise or conversion prices therefor, were adjusted accordingly. CUSIP No. 343389-10-2 13D Page 6 of 7 Pages In order to induce all of the holders of Preferred Stock of the Company (including the Reporting Person) to convert all outstanding shares of Preferred Stock into shares of Common Stock of the Company, contemporaneously with the consummation of the Company's proposed merger with CESI, the Company reduced the conversion price per share to $0.027 per share, on a pre-stock split basis (or $3.24 per share on a post-stock split basis). On October 31, 2001, the Reporting Person converted all shares of Preferred Stock owned by him (inclusive of all accrued but unpaid dividends thereon) into an aggregate of 37,857 shares of Common Stock (on a post-stock split basis). ________________________________________________________________________________ Item 5. Interest in Securities of the Issuer. (a) The aggregate number and percentage of shares of Common Stock beneficially owned by the Reporting Persons on the date hereof are 78,315 shares of Common Stock (inclusive of (i) 74,566 shares of Common Stock owned of record by the Reporting Person, (ii) 2,083 shares of Common Stock issuable upon exercise of stock options owned by the Reporting Person and (iii) 1,666 shares of Common Stock owned of record by Marlin, as the Reporting Person is the sole managing member of Marlin), or approximately 1.6% of the 4,852,779 shares of Common Stock that would have been issued and outstanding as of the date hereof pursuant to Rule 13d-3 (d) (1) (i) of the Exchange Act (i.e., 4,850,696 shares of Common Stock that were actually issued and outstanding as of November 13, 2001, as set forth in the Company's Form 8K dated November 13, 2001, plus an aggregate of 2,083 shares of Common Stock issuable upon exercise of stock options owned by the Reporting Person). (b) The Reporting Person may be deemed to have the sole power to vote (and to direct the vote of) and to dispose of (and direct the disposition of) the 76,649 shares of Common Stock directly beneficially owned by him (inclusive of the 2,083 shares of Common Stock issuable to him upon the exercise of the stock options owned by him, in addition to the 74,566 shares of Common Stock owned of record by him). In addition, the Reporting Person, as sole managing member of Marlin, may be deemed to share the power to vote (and direct the vote of) and to dispose of (and direct the disposition of) the 1,666 shares of Common Stock owned of record by Marlin. (c) Except for the acquisition by the Reporting Person of shares of Common Stock upon (i) the exercise of all Preferred Stock Warrants owned by the Reporting Person and (ii) the conversion of all shares of Preferred Stock owned by the Reporting Person, in each case, as more fully described in Items 3 and 4 above, during the past 60 days, the Reporting Person has not effected any transaction in the Common Stock. (d) Except for the members of Marlin (inclusive of the Reporting Person) who have an indirect interest in the securities of the Company owned of record by Marlin pursuant to the terms of the LLC Agreement described in Item 6 of the First Amendment, no other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any of the securities of the Company beneficially owned by the Reporting Person. (e) The Reporting Person ceased to be the beneficial owner of more than five percent of the Common Stock on October 31, 2001.
