  Item 5.   Other Events.
            ------------ 
  
       On December 31, 1997 the Registrant entered into an Equipment Financing
  Agreement (the "Agreement") with Pentech Financial Services, Inc. ("Pentech")
  pursuant to which Pentech has committed up to $1,000,000 to the Registrant under
  an Equipment Financing Commitment (the "Commitment") secured by all of the
  Registrant's fixed assets. The terms of the Agreement provide that the
  Registrant will make payments of 3.767% on any advances thereunder payable in 30
  monthly installments, with an additional final payment equal to 12% of the
  advance due and payable upon the expiration of any such 30-month payment period.
  The commitment represented by the Agreement will expire on January 31, 1998, but
  may be extended by Pentech for a period of 90 days upon a review of the
  Registrant's financial condition at the expiration date.
  
       Also on December 31, 1997 the Registrant requested an advance of $500,000
  (the "First Advance Amount") under the Commitment to be used for general
  corporate purposes and the nationwide roll-out of the Registrant's recently
  introduced Parent's Alert(R) Home Drug Test Service. In accordance with the
  terms of the Agreement, the First Advance Amount will be due and payable in 30
  monthly installments of $18,835 each, commencing on February 1, 1998, with a
  final payment of $60,000 due and payable upon the expiration of the
  aforementioned 30-month payment period.
  
          The terms of the Commitment provide that an additional $250,000 (the
  "Second Advance Amount") will be made available to the Registrant under the
  Commitment upon the successful closing of a private placement of the
  Registrant's equity securities in the minimum amount of $1.5 million by
  January 15, 1998. Pentech has agreed, however, to make available to the
  Registrant the Second Advance Amount if the Registrant closes a private
  placement of its equity securities in the minimum amount of $1.3 million by
  January 30, 1998. In addition, the final $250,000 (the "Third Advance Amount")
  will be made available to the Registrant under the Commitment upon the
  successful closing of a second private placement of the Registrant's equity
  securities in the minimum amount of $1.8 million by April 30, 1998.
