2 4 Alliance Holding Corporation, a Delaware corporation ("Alliance"), and Mr. Joseph E. LoConti (together, the "Reporting Persons" and individually, the "Reporting Person") hereby make the following statement pursuant to Section 13(d) of the Securities Exchange Act of 1934 (the "Exchange Act") and the rules and regulations promulgated thereunder. This Statement is an amendment to the Schedule 13D dated October 18, 1996, as amended by the Schedule 13D dated January 31, 1997 and the Schedule 13D dated April 3, 1997, filed by each of the Reporting Persons (collectively, the "Original Schedule 13D"). ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. On April 21, 1997, MGD Holdings Ltd., a Bermuda corporation controlled by Mr. Michael G. DeGroote ("MGD"), purchased from International Alliance Services, Inc. (the "Issuer") an aggregate of 555,556 units of the Issuer for $9.00 per unit in a private placement. Each unit is comprised of one share of common stock, $.01 par value per share, of the Issuer ("Common Stock") and one warrant to purchase one share of Common Stock at an exercise price of $11.00 per share, exercisable for a three year period from the date of issuance (a "Unit"). As a result of the voting trust described in the Original Schedule 13D (the "Voting Trust"), the Reporting Persons are deemed to beneficially own the 555,556 shares of Common Stock acquired by MGD in such transaction. No consideration was paid by either Reporting Person in connection with such acquisition. ITEM 4. PURPOSE OF THE TRANSACTION The Reporting Persons are deemed to have acquired the securities described in Item 3 as a result of the Voting Trust and had no role in the decision resulting in such acquisition. In addition, the Reporting Persons share neither investment control nor a pecuniary interest in any of the securities described in Item 3. ITEM 5. INTEREST IN SECURITIES OF ISSUER (a)(i) As of May 1, 1997, Alliance beneficially owned an aggregate of 7,751,556 shares of Common Stock constituting approximately 21.6% of the 35,968,419 shares of Common Stock deemed outstanding as of May 1, 1997. All of the shares of Common Stock beneficially owned by Alliance are owned of record by Westbury pursuant to the terms of the Voting Trust. On March 25, 1997, Alliance and Westbury entered into an agreement to terminate such Voting Trust, subject to the receipt of any necessary regulatory approvals. Accordingly, if and when such approval is obtained, Alliance would not beneficially own any shares of Common Stock and would no longer be a reporting person for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended. (ii) As of May 1, 1997, Mr. LoConti beneficially owned an aggregate of 14,435,856 shares of Common Stock, which includes warrants to purchase 688,800 shares of Common Stock and 7,751,556 shares of Common Stock owned of record by Westbury, representing approximately 39.4% of the 35,968,419 shares of Common Stock deemed outstanding as of May 1, 1997. Mr. LoConti disclaims beneficial ownership of such shares except to the extent of his pecuniary interest. 3 5 Mr. LoConti has indirect beneficial ownership of the shares of Common Stock owned of record by Westbury as a result of the Voting Trust. If and when regulatory approval is obtained to terminate such trust, Mr. LoConti would beneficially own 6,684,300 shares of Common Stock constituting approximately 18.4% of the 35,968,419 shares of Common Stock deemed outstanding as of May 1, 1997. (b)(i) As of May 1, 1997, Alliance shared voting power with respect to 7,751,556 shares of Common Stock owned of record by Westbury pursuant to the Voting Trust. (ii) As of May 1, 1997, Mr. LoConti shared voting power with respect to 7,751,556 shares of Common Stock owned of record by Westbury. In addition, Mr. LoConti has sole voting and investment power with respect to an additional 6,684,300 shares of Common Stock. (c) Within the last 60 days, the Reporting Persons and persons named in Item 2 have affected the following transactions not previously reported: (i) On April 21, 1997, as a result of the Voting Agreement, the Reporting Persons are deemed to have acquired 555,556 shares of Common Stock.
