</TABLE>
    

   
(1)      The number of shares of the Common Stock of U.S. Alcohol Testing of
         America, Inc. ("USAT") being registered is based on (a) an estimate as
         to the approximate number of USAT shares to be issued to the minority
         stockholders of U.S. Drug Testing, Inc. ("U.S. Drug") in connection
         with the merger of U.S. Drug with and into U.S. Drug Acquisition
         Corp., a wholly-owned subsidiary of USAT; (b) an estimate as to the
         approximate number of USAT shares to be issued upon the exercise of the
         USAT Warrants to be issued upon the merger in exchange for U.S. Drug
         Warrants; and (c) the assumption that no U.S. Drug Options will be
         exercised prior to the merger, in all three instances assuming a $2.00
         per share market price for the USAT shares, which is the closing sales
         price on August 7, 1996.

(2)      Estimated solely for the purpose of calculating the registration fee.
         The proposed maximum offering price and the registration fee (a) for
         the shares to be issued upon the merger are computed, pursuant to Rule
         457(a), on the basis of a $2.00 value per share estimate for the price
         to be determined in accordance with the terms of the merger and (b)
         for the shares to be issued upon exercise of the USAT Warrants are
         computed, pursuant to Rule 457(g), on the basis of the assumed
         exercise price of the USAT Warrants if 393,750 shares are subject
         thereto.

(3)      Estimated solely for the purpose of calculating the registration fee.
         The Special Payment value is calculated as follows: As the 1,721,900
         shares of the Minority U.S. Drug Common Stock constitute approximately
         33.0% of the 5,221,900 shares of the U.S. Drug Common Stock, for a
         Special Payment estimated at $10,000,000 to Acquisition Corp. by a
         development partner, the U.S. Drug Minority Stockholders would
         receive, at a maximum, an aggregate of approximately one-third of 33%
         of $10,000,000 or an aggregate of approximately $1,100,000 (i.e., 11%
         of $10,000,000 or $.64 per share).
    

                        ________________________________

         The Registrant hereby amends this Registration Statement on such date
         or dates as may be necessary to delay its effective date until the
         Registrant shall file a further amendment which specifically states
         that this Registration Statement shall thereafter become effective in
         accordance with Section 8(a) of the Securities Act of 1933 or until
         the Registration Statement shall become effective on such date as the
         Commission, acting pursuant to said Section 8(a), may determine.

                             AVAILABLE INFORMATION

         USAT and U.S. Drug are each subject to the informational requirements
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and,
in accordance therewith, each files reports, proxy and information statements
and other information with the Securities and Exchange Commission (the
"Commission").  Reports, proxy and information statements and other information
filed with the Commission can be inspected and copied at the public reference
facilities of the Commission at Room 1024, 450 Fifth Street, N.W., Washington,

also be obtained at prescribed rates from the Public Reference Section of the

BACKGROUND OF THE COMPANY

         USAT was incorporated on April 15, 1987 under the laws of Delaware to
design, manufacture and market instruments which measure blood alcohol
concentration by breath sample and analyzation.  USAT maintains its principal
executive offices at 10410 Trademark Street, Rancho Cucamonga, California
91730, and its telephone number is (909) 466-8378.  USAT and its subsidiaries
will be collectively referred to herein as the "Company."

         USAT's subsidiaries, which include U.S. Drug, operate in several
different industries:

   
         1.      U.S. Drug, which is 67.0% owned by USAT and whose common stock
trades on the Pacific Stock Exchange, is developing proprietary systems that
will test for drug use.

         2.      Good Ideas Enterprises, Inc. ("Good Ideas"), which is 60.8%
owned by USAT and whose common stock, $.001 par value (the "Good Ideas Common
Stock"), also trades on the Pacific Stock Exchange, designed, markets and
distributes a variety of traditional toy products for children of various ages.
    


                                       3
<PAGE>   9
         3.      ProActive Synergies, Inc. ("ProActive"), which is a
wholly-owned subsidiary of USAT incorporated in June 1995, provides single
source services to assist corporations in their hiring practices ranging from
substance abuse testing and background screening to total program management.

   
         4.      On May 21, 1996, the Company completed its acquisition of
Robert Stutman & Associates, Inc. ("RSA"), a provider of corporate drug-free
work place programs.  Since January 1996, RSA has been designing policies and
programs on substance abuse prevention for customers of the ProActive
subsidiary.

         5.      Alconet, Inc. ("Alconet"), which is a wholly-owned subsidiary
acquired by USAT in March 1995, has developed an alcohol testing network to
upload test results and information from various alcohol breath testing
devices.
    

         U.S. Rubber Recycling, Inc. ("USRR"), which is a wholly-owned
subsidiary of USAT, manufactured and marketed floor covering products for
office and industrial use from used truck and bus tires.  On April 30, 1996,
USRR sold its assets to an unaffiliated third party and discontinued
operations.  See "Business of the Company-Subsidiaries-U.S. Rubber Recycling,
Inc."

         Acquisition Corp. was incorporated on December 18, 1995 under the laws
of Delaware as a wholly-owned subsidiary of USAT for the sole purpose of
acquiring U.S. Drug and will engage in no business operations until after
consummation of the Merger.  Acquisition Corp.'s Board of Directors consists of
three USAT directors who have no direct affiliation with U.S. Drug.

         The USAT Common Stock is currently traded on the American Stock
Exchange under the symbol "AAA".  See "USAT Market Information-Market Data."

   
         U.S. Drug was incorporated on October 8, 1992 under the laws of
Delaware.  Effective as of January 1, 1993, USAT transferred or sub- licensed
to U.S. Drug all of its assets and intellectual property rights related to drug
testing operations in exchange for 3,500,000 shares of the U.S. Drug Common
Stock.  U.S. Drug maintains its principal executive offices at 10410 Trademark
Street, Rancho Cucamonga, CA 91730 and its telephone number is (909) 466-8378,
which are the same as USAT's.  U.S. Drug's current Board of Directors is made
up of three directors, all of whom were elected on May 31, 1996, one of whom is
a consultant to the USAT Board of Directors and the other two of whom are
executive officers, directors and employees of USAT.  See "Risk Factors-USAT
Affiliations of U.S. Drug Directors" and "Material Contacts of USAT with U.S.
Drug."

         U.S. Drug is developing proprietary systems that will test for drug
use, including the following five commonly used drugs of abuse: cocaine,
opiates (heroin, morphine and codeine), phencyclidine hydrochloride (PCP),
amphetamines (including methamphetamines) and tetrahydrocannabinol (THC,
marijuana). Its line of products under development are based on its sub-license
from USAT for drugs of abuse detection utilizing the United States Navy ("USN")
patent for flow immunosensor technology.  U.S. Drug is developing its own
proprietary "Immunoassay Chemistry" for these five drugs which will work with
the USN developed technology.  U.S. Drug has received six Food and Drug
Administration ("FDA") marketing approvals covering its Model 9000 Flow
Immunoassay System and the attendant assays for each of the five drugs of abuse
listed above, using urine as the test medium.  U.S. Drug, based on its review
of current market conditions, has decided to defer completion of the
calibrators and the other elements required to be completed in order to market
the urine medium testing product until it can complete the assays for a saliva
medium testing product and, as a result, has produced no revenues through the
date hereof.  Until FDA approval is obtained of the saliva medium product and
marketing has commenced, no revenues will be generated from sales to users.
U.S. Drug has commenced research using saliva as a testing medium in connection
with the flow immunosensor technology, is currently conducting a feasibility
study as to the product and, assuming a favorable conclusion with respect to
such study and subsequent success in the remainder of the development program,
currently expects to submit its five-panel screening assay to the FDA late in
1997, but there can be no assurance that such submission will occur by such
date.  U.S. Drug's management expects marketing of the U.S. Drug products to
commence six months to a year later, but there can be no assurance as to when
FDA approval will be given or when marketing will commence.  Accordingly, it
may be 20 to 30 months before any revenues from sales of products will be
generated by U.S. Drug.  See "Business of U.S. Drug."

         The U.S. Drug Common Stock is currently traded on the Pacific Stock
Exchange under the symbol "U.S.D.P." See "U.S. Drug Market Information-Market
Data."  If the Merger is consummated, trading in the U.S. Drug Common Stock
will cease on the effective date thereof and the registration of such security
under Section 12(b) of the Exchange Act will be terminated.

         USAT is also concurrently seeking to acquire the minority stock
interests in Good Ideas by an offer of shares of the USAT Common Stock to the
minority stockholders of Good Ideas as consideration for their consent to a
merger of Good Ideas Acquisition Corp., a newly-incorporated wholly-owned
subsidiary of USAT, with and into Good Ideas.  See "Business of the
Company-Subsidiaries-U.S. Drug Testing, Inc."  There can be no assurance that
the Good Ideas Merger will be successfully consummated.  The acquisition of
Good Ideas is not a condition to the Merger.

THE CONSENT PROCEDURE

(1)  STATUTORY BASIS

         Unless a corporation's certificate of incorporation otherwise
provides, Section 228 of the Delaware General Corporation Law (the "GCL")
permits stockholders' actions without a meeting of stockholders and without
prior notice if a consent or consents in writing, setting forth the action so
taken, is or are signed by the holders of the outstanding voting stock having
not less than the minimum number of votes that would be necessary to take such
action at a meeting at which all shares entitled to vote thereon were present.
U.S. Drug's certificate of incorporation does not otherwise provide, so that a
consent procedure pursuant to Section 228 of the GCL may be utilized by USAT.
Under such section of the GCL, an action taken by consent is effective when
written consents from the holders of record of the minimum number of
outstanding shares of the voting stock necessary to authorize the action are
executed and delivered to the corporation within 60 days of the earliest dated
consent delivered in accordance with the GCL to the corporation.  Under Section
251 of the GCL, a domestic corporation may be merged with and into another
domestic corporation by the affirmative vote of the record holders of a
majority of the outstanding shares of the voting stock acting without a meeting
and without prior notice.  Accordingly, USAT as the owner of 67.0% of the U.S.
Drug Common Stock, which is the sole voting stock in U.S. Drug, could adopt the
Merger Agreement without any other stockholder voting in favor of the adoption
of the Merger Agreement.  Notwithstanding the foregoing, the Merger Agreement
provides that it is a condition to the consummation of the Merger that the
record holders of more than 50% of the outstanding shares of the U.S. Drug
Common Stock owned by U.S. Drug stockholders other than USAT (i.e., the U.S.
Drug Minority Stockholders) consent to the adoption of the Merger Agreement.
USAT will execute and deliver a consent to the adoption of the Merger Agreement
as a stockholder of U.S. Drug after the holders of more than 50% of the
outstanding shares of the Minority U.S. Drug Common Stock have consented in
order to permit the filing of a Certificate of Merger in Delaware pursuant to
the GCL and the terms of the Merger Agreement.  USAT will not execute and
deliver its consent if the consents of the holders of more than 50% of the
outstanding shares of the Minority U.S.  Drug Common Stock are not obtained.

(2)  PROCEDURE TO CONSENT

         UNDER THE GCL, ONLY HOLDERS OF RECORD ON THE RECORD DATE (AS DEFINED
BELOW) ARE ELIGIBLE TO GIVE THEIR CONSENT TO THE ADOPTION OF THE MERGER
AGREEMENT.  ANYONE OWNING SHARES BENEFICIALLY (BUT NOT OF RECORD), SUCH AS A
PERSON WHOSE OWNERSHIP OF SHARES IS THROUGH A BROKER, BANK OR OTHER FINANCIAL
INSTITUTION, WHO WISHES





                                       6
<PAGE>   12
TO GIVE THEIR CONSENT SHOULD CONTACT THAT BROKER, BANK OR FINANCIAL INSTITUTION
WITH INSTRUCTIONS TO EXECUTE THE WHITE FORM OF CONSENT ON HIS OR HER BEHALF OR
TO HAVE THE BROKER, BANK OR FINANCIAL INSTITUTION'S NOMINEE EXECUTE THE
CONSENT.

         USAT is soliciting the written consents referred to herein and, if a
stockholder wishes to consent, the white consent card should be returned to
Georgeson & Company Inc., Wall Street Plaza, New York, New York 10005, in the
enclosed envelope or to U.S. Drug Testing, Inc., 10410 Trademark Street, Rancho
Cucamonga, California 91730, Attention: Secretary.

(3)  REVOCATION

         An executed consent card may be revoked at any time before expiration
by marking, dating, signing and delivering a written revocation before the time
that sufficient unrevoked consents have been received to authorize the action
for which consents are solicited.  As indicated above, consents must be
received within 60 days after the first consent is delivered to U.S. Drug.  A
revocation may be in any written form validly signed by the record holder as
long as it clearly states that the consent previously given is no longer
effective.  The delivery of a subsequently dated consent card which is properly
completed will constitute a revocation of any earlier consent.  The revocation
may be delivered to Georgeson & Company Inc., Wall Street Plaza, New York, New
York 10005 or to U.S. Drug Testing, Inc., 10410 Trademark Street, Rancho
Cucamonga, California 91730, Attention: Secretary.

(4)  MISCELLANEOUS

         ABSTAINING FROM GIVING A CONSENT OR NOT RETURNING A SIGNED CONSENT
WILL HAVE THE SAME EFFECT AS WITHHOLDING CONSENT TO THE PROPOSED ACTION.  IF
YOU ARE THE STOCKHOLDER OF RECORD AND WISH TO GIVE YOUR CONSENT, PLEASE SIGN,
DATE AND RETURN THE ENCLOSED WHITE CONSENT CARD PROMPTLY IN THE ENVELOPE
PROVIDED.

   
         IF YOUR SHARES OF THE U.S. DRUG COMMON STOCK ARE HELD IN THE NAME OF A
BROKERAGE FIRM, BANK OR NOMINEE, ONLY THEY CAN CONSENT TO THE MERGER AND ONLY
UPON RECEIPT OF YOUR SPECIFIC INSTRUCTIONS.  ACCORDINGLY, IF YOU WISH TO GIVE
YOUR CONSENT, PLEASE CONTACT THE PERSON RESPONSIBLE FOR YOUR ACCOUNT AND GIVE
INSTRUCTIONS WITH RESPECT TO SUCH SHARES IMMEDIATELY.
    

(5)  RECORD DATE, QUORUM AND REQUIRED VOTE

   
         Only holders of record of shares of the U.S. Drug Common Stock on
August __, 1996 (the "Record Date") will be entitled to consent to adoption of
the Merger Agreement.
    


                                       7
<PAGE>   13
   
         On the Record Date, there were 5,221,900 shares of the U.S. Drug
Common Stock outstanding, of which 1,721,900 shares were the Minority U.S. Drug
Common Stock.  The affirmative consent of the holders of more than 50% of the
outstanding shares of the Minority U.S. Drug Common Stock is necessary to adopt
the Merger Agreement.  Thus, the holders of at least 860,951 shares of the
1,721,900 shares of the Minority U.S.  Drug Common Stock must consent to the
adoption of the Merger Agreement.  (USAT intends not to include an aggregate of
78,400 shares held by a current director of USAT, a former director of USAT and
U.S. Drug and a person who is a director of U.S. Drug and consultant to USAT
and his affiliates in determining whether it has a majority; however, if the
necessary consents are obtained, these holders will receive shares of the USAT
Common Stock, and share in the Special Payment (as hereinafter defined), on the
same basis as the other U.S. Drug Minority Stockholders.) See the subsections
"The Consent Procedure-Miscellaneous" and "Special Payment" under the caption
"Terms of the Transaction".  USAT will execute and deliver a consent to such
adoption only after the holders of more than 50% of the Minority U.S. Drug
Common Stock (excluding the aforesaid 78,400 shares from such computation) have
consented in order to permit filing of a Certificate of Merger in Delaware
pursuant to the GCL and the terms of the Merger Agreement.

         On February 6, 1996, the Board of Directors of USAT, acting on behalf
of USAT as the sole stockholder of Acquisition Corp., adopted the Merger
Agreement.  On April 23, 1996, the Acquisition Board authorized execution of
the Merger Agreement.  Accordingly, Acquisition Corp. has approved the Merger.
    

(6)  APPRAISAL RIGHTS

         The U.S. Drug Minority Stockholders will have no rights of appraisal
under the GCL with respect to the consummation of the Merger.  See "Terms of
the Transaction-The Consent Procedure-Rights of Dissenting U.S. Drug
Stockholders."

THE MERGER

(1)  GENERAL

   
         Pursuant to the Merger Agreement, U.S. Drug will be merged with and
into Acquisition Corp. (the "Merger") and each outstanding share of the
Minority U.S. Drug Common Stock will be converted into __________ shares of the
USAT Common Stock and __________ Rights entitling the holder thereof to receive
a proportionate share of the Special Payment in cash.  See the section "Special
Payment" under the caption "Terms of the Transaction."  The shares of the U.S.
Drug Common Stock owned by USAT will be canceled upon the Merger becoming
effective.  Such exchange ratio reflected an offer of shares of the USAT Common
Stock having a value of $5.25 per share determined on the basis
    





                                       8
<PAGE>   14
   
of the average of the closing sales prices of the USAT Common Stock during the
30 calendar days prior to the Record Date, which average price was $_____ per
share.  An aggregate of _________ shares of the USAT Common Stock will be
issued to the U.S. Drug Minority Stockholders, subject to adjustment for
fractional shares.  Assuming that there are no exercises of outstanding Common
Stock purchase warrants or stock options or any conversions of USAT preferred
stock between the date of this Consent Solicitation Statement/Prospectus and
the effective date of the Merger, the USAT stockholders will own ____% of the
outstanding shares of the USAT Common Stock and the U.S. Drug Minority
Stockholders will own ____%.  The shares of the U.S. Drug Common Stock owned by
USAT will be cancelled.  Holders of the Minority U.S. Drug Common Stock may
receive an additional payment based on payments, if any, by a development
and/or marketing partner if the search for such a partner is initiated and
successful and if an arrangement is negotiated pursuant to which such partner
obtains marketing rights in return for immediate payments to Acquisition Corp.
or USAT within one year of the Effective Date (as defined below).  See "Terms
of the Transaction-Special Payment."
    

(2)  OPTIONS AND WARRANTS

   
         As of the Record Date, there were outstanding options expiring October
2, 2004 (the "U.S Drug Options") to purchase an aggregate of 152,000 shares of
the U.S. Drug Common Stock and Common Stock purchase warrants expiring October
13, 1998 (the "U.S. Drug Warrants") to purchase an aggregate of 150,000 shares
of the U.S. Drug Common Stock at $7.00 per share.  Three former directors of
U.S. Drug who hold U.S.  Drug Options to purchase an aggregate of 110,000
shares of the U.S. Drug Common Stock have agreed to waive their rights under
such Options upon the consummation of the Merger.  The remaining U.S. Drug
Options to purchase an aggregate of 42,000 shares of the U.S. Drug Common Stock
have, by their terms, become exercisable only until the effective date of the
Merger and, because USAT has declined to assume them, the Options will expire
if not so exercised.  Because of the higher exercise price as compared to the
USAT offer, USAT does not anticipate any exercise.

         The U.S. Drug Warrants are owned by Baraban Securities, Inc.
("Baraban"), the underwriter of the initial public offering of the U.S.  Drug
Common Stock, and Baraban's designees.  The exercise price of the U.S. Drug
Warrants is $7.50 per share and was initially negotiated by Baraban with U.S.
Drug at 150% of the public offering price of $5.00 per share of the U.S. Drug
Common Stock in U.S. Drug's initial public offering.  If the Merger is
consummated, as a result of the anti-dilution provisions of the U.S. Drug
Warrants, the U.S. Drug Warrants will be converted into USAT Common Stock
purchase warrants expiring October 13, 1998 to purchase an aggregate of
__________ shares of the USAT Common
    


                                       9
<PAGE>   15
   
Stock, which is the same number of shares of the USAT Common Stock which the
holders of the U.S. Drug Warrants would have been entitled to receive after the
consummation of the Merger had the U.S. Drug Warrants been exercised
immediately prior to the consummation of the Merger.  The exercise price of the
Merger Warrants will be proportionately adjusted to $_________ per share.  The
same anti-dilution provisions as were applicable to the U.S. Drug Warrants will
be applicable to the Merger Warrants.  See "The Merger and Related Matters-U.S.
Drug Options and Warrants."
    

(3)  RECOMMENDATIONS BY THE BOARDS OF DIRECTORS

   
         On November 16, 1995, the Board of Directors of USAT approved in
principle seeking the acquisition of the minority stockholder interests in U.S.
Drug and, on February 6, 1996, authorized execution of the Merger Agreement at
an exchange ratio whereby U.S. Drug Minority Stockholders shall receive shares
of the USAT Common Stock having a value of $5.25 per share of the U.S. Drug
Common Stock.  On April 23, 1996, the U.S. Drug Board of Directors authorized
execution of, and submission to the U.S. Drug Minority Stockholders for
approval of, the Merger Agreement. In taking such action, the U.S. Drug Board
concluded that the offer was fair to the U.S. Drug Minority Stockholders from a
financial point of view (a conclusion also reached by the USAT Board) and
recommended to the U.S. Drug Minority Stockholders that they adopt the Merger
Agreement.  In setting the exchange ratio at the February 6th meeting, each
Board considered the exchange ratio as being within an acceptable range as to
the number of shares of the USAT Common Stock to be issued that would be fair
to the U.S. Drug Minority Stockholders and, in the case of USAT's Board of
Directors, would also be fair to the USAT Stockholders.  On August __, 1996,
each Board satisfied itself that the number of shares of the USAT Common Stock
to be issued to the U.S. Drug Minority Stockholders determined in accordance
with the exchange ratio set on February the 6th still was within the acceptable
range as to the number of shares previously considered.  The U.S. Drug Board
directs the attention of the U.S. Drug Minority Stockholders to the affiliation
of the directors of U.S. Drug with USAT.  See the subsection "Affiliation of
USAT and U.S. Drug" in this section "The Merger" under this caption "Summary,"
"Risk Factors-USAT Affiliations of U.S. Drug Directors" and "Material Contacts
of USAT with U.S. Drug."  For a review of the factors each of the USAT Board
and the U.S. Drug Board considered in making its decision, see "The Merger and
Related Matters-Reasons for the Merger and Approval."
    

   
(4)  AFFILIATION OF USAT AND U.S. DRUG

         USAT owns 67.0% of the outstanding shares of the U.S. Drug Common
Stock.  Of the three directors of U.S. Drug who approved the Merger on April
23, 1996, all were then executive officers
    





                                       10
<PAGE>   16
   
and employees of USAT, two were directors and the other a former director of
USAT and all were stockholders of USAT.  Of the current three directors, two
are executive officers, directors and employees of USAT and the other is a
consultant to the USAT Board.  All three are securityholders of USAT.  As of
March 31, 1996, there was an indebtedness from USAT to U.S. Drug in the amount
of $282,295, which, as extended, was due June 30, 1996.  This indebtedness was
paid in June 1996 and USAT has authorized a loan of $500,000 to U.S. Drug which
will be due December 31, 1996.

         Because of the foregoing relationships with USAT, the U.S. Drug Board
has never been independent of USAT and all of the directors have owed fiduciary
duties to both USAT and U.S. Drug, creating a conflict of interests.  This
condition has existed since U.S. Drug was incorporated as a wholly-owned
subsidiary of USAT in October 1992.  As a result of these conflicts of
interest, the U.S. Drug Board has approved certain safeguards for the U.S. Drug
Minority Stockholders, i.e, a majority of them must approve the Merger for it
to be consummated, a fairness opinion has been obtained and independent counsel
for U.S. Drug was engaged.  See "The Merger and Related Matters-Reasons for the
Merger and Approval."

(5)  FAIRNESS OPINION

         The Board of Directors of U.S. Drug has received an opinion from Whale
Securities Co., L.P. ("Whale Securities") as to the fairness of the Merger to
the U.S. Drug Minority Stockholders from a financial point of view as of the
date of the opinion.  A copy of such opinion is annexed as Appendix B hereto
and should be read in its entirety.  See "The Merger and Related
Matters-Fairness Opinion."

(6)  THE MERGER AGREEMENT
    

         Following the satisfaction or waiver of the conditions of the Merger,
the Merger will become effective upon the filing in the State of Delaware of a
Certificate of Merger in accordance with Sections 103 and 251 of the GCL.  (The
date of such filing in Delaware is referenced to herein as the "Effective
Date.")  As soon as practical after the Effective Date, a notice of
consummation of the Merger, together with a letter of transmittal for use in
surrendering certificates for shares of the U.S. Drug Common Stock, will be
mailed to the holders of record as of the Effective Date of the shares of the
Minority U.S. Drug Common Stock.  The U.S. Drug Minority Stockholders are
requested not to surrender their certificates for shares of the Minority U.S.
Drug Common Stock until they receive such a letter of transmittal.  See "The
Merger and Related Matters-Exchange of Certificates."

<PAGE>   17
   
(7)  CONDITIONS OF THE MERGER

         The obligations of USAT, U.S. Drug and Acquisition Corp. to consummate
the Merger are subject to the satisfaction of the following conditions, among
others: (1) the Merger Agreement shall have been adopted by the holders of at
least 50% of the outstanding shares of the Minority U.S. Drug Common Stock,
even though the consent of USAT alone would have been sufficient to have
adopted the Merger Agreement in accordance with the GCL, and (2) this
Registration Statement shall have been declared effective by the Commission
under the Securities Act and no stop order suspending such effectiveness shall
have been issued or a proceeding for such purpose shall have been instituted.
No party to the Merger Agreement may waive either of the foregoing conditions.
There exist other conditions to consummation of the Merger that may be waived
(other than the requirement of a fairness opinion) if the respective Board
considers such waiver to be in the best interest of the stockholders of its
respective corporation.  See "The Merger and Related Matters-Conditions to the
Merger" and the Merger Agreement attached as Appendix A hereto for additional
information as to the conditions of the Merger.

(8)  AMENDMENT AND TERMINATION
    

         The Merger Agreement may be amended in writing at any time prior to
the Effective Date by the Boards of Directors of the parties thereto, whether
before or after the adoption by the U.S. Drug Minority Stockholders of the
Merger Agreement, but, after such adoption, no amendment may, without further
approval by such stockholders, alter or change the amount or kind of
consideration to be received in exchange for the shares of the Minority U.S.
Drug Common Stock.

         The Merger Agreement may be terminated and the Merger may be abandoned
at any time prior to the Effective Date, whether before or after the adoption
of the Merger Agreement by the U.S. Drug Minority Stockholders: (1) by mutual
written consent of the Boards of Directors of USAT and U.S. Drug, (2) by either
USAT or U.S. Drug if the respective Board of Directors, based on the opinion of
its outside counsel, determines that making a recommendation to the U.S. Drug
Minority Stockholders to adopt the Merger Agreement could reasonably be deemed
to cause the members of such Board of Directors to breach their fiduciary

RECENT DEVELOPMENTS

         In mid-May 1995, as a result of communications among certain
stockholders of USAT relating to their dissatisfaction with the performance of
the management of USAT in maximizing the value of USAT, Lee S. Rosen, Michael
S. McCord, Arthur Schwartz, Morris B. Black and Stuart S. Greenberg (the then
Chairman of Baraban) formed a stockholders' committee later named "The
Committee for Maximizing Stockholder Value of U.S. Alcohol Testing of America,
Inc. (the "Committee") to make recommendations to the management of USAT.  On
July 5, 1995, Mr. Black resigned from the Committee for personal reasons and,
on July 19, 1995, Peter M. Mark joined the Committee.  Between May 12, 1995 and
August 17, 1995, the Committee or affiliated stockholders took certain actions,
including the formulation of certain recommendations by the Committee which it
attempted to communicate to management.

         On August 17, 1995, the Committee determined to seek consents (1) to
remove and replace incumbent directors with its own nominees; (2) to amend the
by-laws of USAT to delete the provision that establishes three classes of
directors on USAT's Board of Directors; and (3) to amend the by-laws of USAT to
fix the number of directors at seven instead of five and to require that a
majority of the directors be independent.  On September 11, 1995, the
Committee, acting through Georgeson & Company Inc. as its solicitation agent,
first delivered and mailed definitive consent solicitation material pursuant to
Regulation 14A under the Exchange Act to brokers and certain stockholders of
record of USAT.  USAT thereafter initiated an action in the Delaware District
Court alleging that the Committee had violated Section 14 of the Exchange Act,
sent out a "stop, look and listen letter" and filed its preliminary consent
revocation statement.

         On September 26, 1995, as reported in USAT's Current Report on Form
8-K filed on October 2, 1995, the following events occurred:

   
         a.      the Committee and USAT settled the above litigation;

         b.      the number of directors of USAT was increased from five to
seven;

         c.      incumbent directors Glenn A. Bergenfield, William DiTuro and
Gary S. Wolff resigned as directors of USAT; however, they continued to serve
as directors of U.S. Drug and Good Ideas (Mr. Bergenfield and Dr. DiTuro
subsequently resigned as
    





                                       14
<PAGE>   20
   
directors of both subsidiaries on November 16, 1995 and Mr. Wolff resigned as a
director of both subsidiaries on July 3, 1996);

         d.      Alan I. Goldman, a nominee of the Committee, Peter M. Mark, a
member of the Committee, and Lee S. Rosen, a member of the Committee and also a
Committee nominee, were elected as directors of USAT;

         e.      John C. Lawn and Linda H. Masterson were elected as directors
of USAT (Prior to their election as directors, neither Mr. Lawn nor Ms.
Masterson had any affiliation with USAT or the Committee, although Ms.
Masterson had been interviewed by he Committee as a possible executive officer
if changes were required as the result of a successful consent solicitation and
Mr. Lawn had been recommended to the Committee as a possible candidate for a
directorship by the Committee's counsel (now general counsel to USAT)); and

         f.      James C. Witham, Chairman of the Board, President and Chief
Executive Officer, and Karen B. Laustsen, Executive Vice President, continued
to serve USAT in such capacities and as directors until April 18, 1996 (see
second succeeding paragraph), while Gary S.  Wolff remained as Chief Financial
Officer on an interim basis until his resignation on July 3, 1996.  See "USAT
Management."
    

         At the Annual Meeting of Stockholders held on February 7, 1996, Mr.
Witham and Ms. Laustsen were elected to serve for a one-year term, Messrs.
Goldman and Mark were elected to serve for a two-year term and Messrs. Lawn and
Rosen and Ms. Masterson were elected to serve for a three-year term.

   
         On April 18, 1996, Mr. Witham and Ms. Laustsen resigned their
officerships and directorships in USAT; however, they remained as employees of
USAT until May 31, 1996 to assist in the transition and other matters relating
to the Company, including the Merger.  They continued to serve as directors of
U.S. Drug and Good Ideas until May 28, 1996 in the case of Ms. Laustsen and May
31, 1996 in the case of Mr.  Witham.  The resignations of Mr. Witham and Ms.
Laustsen were voluntary and relationships have continued on a cordial,
cooperative basis since April 18th.

         Recognizing that RSA, a provider of corporate drug-free work place
programs, could bring potential revenues to the Company in what the USAT Board
deemed to be the Company's core businesses, especially if RSA were part of the
Company and not just a consultant, and that Robert Stutman, RSA's President and
founder, was a recognized authority in the area of substance abuse prevention
programs, four of the independent directors of USAT negotiated with Mr. Stutman
on April 17, 1996 the terms for a possible acquisition of RSA.  When Mr. Witham
joined the discussions the next day, he favored naming Mr. Stutman as Chief
    





                                       15
<PAGE>   21
   
Executive Officer of USAT and offered to resign so that there would be no
question as to Mr. Stutman's authority, believing that this would be in the
best interests of the Company and all USAT stockholders.  Ms. Laustsen
subsequently also offered to resign for the same reason.  Recognizing that, as
a result of these offers, USAT would lose two of its principal executive
officers, the remaining directors and Mr. Stutman then negotiated with Ms.
Masterson the terms of her becoming President and Chief Operating Officer of
USAT.

         On April 18, 1996, Mr. Stutman was elected as Chairman of the Board
and a director of USAT and designated as its Chief Executive Officer.  On the
same day, but effective May 13, 1996, Ms. Masterson, a director, was elected as
the President of USAT and designated as its Chief Operating Officer.  Mr.
Stutman and Ms. Masterson were, on May 31, 1996, elected as directors of Good
Ideas and U.S. Drug, as was Michael S. McCord, a former member of the
Committee, a consultant to USAT's Board of Directors and a stockholder of each
of USAT, Good Ideas and U.S.  Drug.

           On May 21, 1996, the Company completed its acquisition of RSA and
RSA became a 100%-owned subsidiary of USAT.  Since January 1996, RSA has been
designing policies and programs for the ProActive subsidiary.  See the section
"Subsidiaries-ProActive Synergies, Inc./Robert Stutman & Associates, Inc."
under the caption "Business of the Company".

                                  RISK FACTORS


         In analyzing this offering, the U.S. Drug Minority Stockholders should
consider all of the matters set forth below:

   
         1.  USAT Affiliations of U.S. Drug Directors.  Of the three directors
of U.S. Drug who approved the Merger on April 23, 1996, all were then executive
officers and employees of USAT, two were directors and the other a former
director of USAT and all were stockholders of USAT.  Of the current three
directors, two are executive officers, directors and employees of USAT and the
other is a consultant to the USAT Board.  All three are securityholders of
USAT.

         Consequently, the U.S. Drug Board of Directors has never been
independent of USAT and all of the directors have owed fiduciary duties to both
USAT and U.S. Drug, creating a conflict of interest, which has existed since
January 1, 1993 when USAT transferred or sub-licensed to U.S. Drug all of its
assets and intellectual property rights related to drug testing operations in
exchange for 3,500,000 shares of the U.S.  Drug Common Stock.   However,
specifically with respect to the Merger, the U.S. Drug Board approved certain
safeguards in an effort to assure fairness to the U.S. Drug Minority
Stockholders.  First, the Merger Agreement must be adopted by the holders of at
least 50% of the outstanding shares of the Minority U.S. Drug Common Stock
(excluding from such calculation the 78,400 shares in the aggregate held by
three current or former directors of U.S. Drug and USAT and the affiliates of
one such director), even though the consent of USAT alone is sufficient to
adopt the Merger Agreement in accordance with the GCL.  Second, a major firm
was engaged as independent counsel for U.S. Drug.  Lastly, the Board of
Directors of U.S. Drug has received an opinion from Whale Securities as to the
fairness of the Merger to the U.S. Drug Minority Stockholders from a financial
point of view as of the date of the opinion.  The Merger Agreement provides
that the first and second protections cannot be waived by any party.

         The USAT Board considered adding independent directors to U.S. Drug,
but rejected the idea because of what it considered the virtual impossibility,
especially in light of today's potential director liability, of finding a
person or persons to accept a directorship in a public company knowing that it
is in the process of going private and that USAT has majority control of the
U.S. Drug Common Stock (68.5% of the outstanding shares as of June 30, 1996 if
the directors' and affiliates' shares are included).  Although USAT could have
attempted to cause U.S. Drug to make it financially attractive for a potential
director to accept a directorship, USAT believed that this would not be a
prudent use of U.S. Drug money and that any such payment or payments could be
perceived as a "bribe" to favor the Merger.

         2.  Operating Losses.  The Company has sustained losses of $41,469,501
from inception through March 31, 1996.  Management initiated cost reduction
actions to reduce selling, general and administrative expenses in fiscal 1996,
which prospective savings were offset by the $903,000 in combined legal and
other expenses incurred by both parties in the consent solicitation contest
(see "Summary-Recent Developments"), $250,000 in settlement of a claim by two
then Alconet officers relating to their then employment and $397,000 of
expenses incurred by Alconet, a subsidiary not included in the fiscal year
ended March 31, 1995 ("fiscal 1995").  Without the expenses of the consent
solicitation, management believes that the selling, general and administrative
expenses can be reduced in the fiscal year ending March 31, 1997 ("fiscal
1997"); however, there can be no assurance that management's expectations will
be realized in fiscal 1997 or thereafter.  In addition, management has
initiated an effort through ProActive, a subsidiary, to tap the human resource
provider market which it believes can result in substantial revenues; acquired
RSA on May 21, 1996, which company has been designing drug-free workplace
policies and programs for ProActive clients since January 1996; will continue
to attempt to sell its toy operations; and has sold on April 30, 1996 the
assets of its rubber recycling operations, so that the Company can concentrate
on alcohol and drug testing and the related RSA/ ProActive operations as its
core businesses.  However, there can be no assurance that management will
receive what it considers to be an acceptable offer for Good Ideas.  In
addition, the Board will liquidate Good Ideas if no acceptable offer is
received by December 31, 1996.  In addition, the decision to develop a saliva
based drug testing product, rather than complete first the urine based drug
testing product for marketing, will, in the opinion of management, enhance the
Company's future growth, but has delayed the receipt of any revenues from U.S.
Drug in fiscal 1996 and fiscal 1997, if not longer, unless revenues are to be
received from a marketing and/or development partner if and when such an
agreement for such a partner is executed, as to which there can be no
assurance, especially because management is not conducting any negotiations for
such a partner.  Accordingly, it is management's belief, especially in view of
the significant losses in, the fiscal year ended March 31, 1994
("fiscal 1994"), fiscal 1995 and fiscal 1996, that, despite these management
programs, the Company will not turn profitable in fiscal 1997 and that, pending
development of the ProActive operations in conjunction with RSA, the timing of
the U.S. Drug development work and the other management programs, it is
currently too speculative to project as to when, if ever, the Company will
become profitable.  See "Business of the Company," "The Company's Financial
Statements" and "The Company's Management's Discussion and Analysis of
Financial Condition and Results of Operations."
    





                                       24

         U.S. Drug has reported losses of $1,640,805 for fiscal 1996,
$2,332,217 for fiscal 1995 and $2,260,292 for fiscal 1994, the decrease being
primarily due to the reduction in licensing royalties to the USN.  U.S. Drug
has not produced any revenues because its products are still in the development
stage as indicated in the preceding paragraph.  Since inception U.S. Drug has
spent $2,556,000 on research and development (which does not give effect to the
$678,000 previously spent by USAT relating to the drug testing products) and
$1,868,000 on selling, general and administrative expenses, as well as
incurring management fees to USAT of $113,000 and interest and depreciation
expenses of $416,024. See "U.S. Drug Financial Statements" and "U.S. Drug's
Management's Discussion and Analysis of Financial Condition and Results of
Operations." Until the development work is completed, governmental approvals
obtained and marketing commenced, the operational losses will continue.
Marketing may not commence for 20 to 30 months and there can be no assurance as
to when, if at all, revenues will be sufficient to exceed U.S.  Drug's costs
and expenses.  See "Business of USAT-Subsidiaries-U.S. Drug Testing, Inc."

         3.  Need for Financing.  Because of the then projected continuing
losses from the Company's operations in fiscal 1996, USAT's management believed
that it was necessary to secure additional equity, through the private
placement of its securities, through the exercise of outstanding Common Stock
purchase warrants or stock options or through a combination of both, in order
to offset the anticipated cash shortfall from operations.  In November 1995,
USAT authorized a private placement pursuant to Regulation D under the
Securities Act offering 2,000,000 shares of the USAT Common Stock which
resulted in $3,750,000 in gross proceeds upon the consummation of the offering
on February 14, 1996.  Management believes that, as a result of this financing,
the proceeds from the sale of the assets of USRR, the recent and possible
future exercises of outstanding USAT Common Stock purchase warrants and stock
options and the cash to be generated from its operations, the Company will be
able to meet its cash requirements during the next 12 months.  However, there
can be no assurance that this objective will be achieved and the Company in
such event would have to seek new financing, which financing may not be
available or, if available, may not be on acceptable terms.  In addition,
depending on market and other conditions relating to the individual holder,
there can be no assurance that the outstanding USAT Common Stock purchase
warrants and stock options of USAT will be exercised and, if exercised, when.
Since January 31, 1996 and through June 30, 1996, Common Stock purchase
warrants to purchase 2,482,824 shares of the USAT Common Stock were exercised
for an aggregate exercise price of $4,421,588.
    

         In the event that the Company is unable to generate sufficient cash
flow from operations or from sources other than





                                       25
<PAGE>   31
   
operations as described in the preceding paragraph (which event, in USAT's
management's opinion, is not likely to occur based upon the Company's past
experience; however, there can be no assurance that management will be
successful in its financing efforts), then the Company may have to reduce
operations in order to survive, thereby not only resulting in less cash from
operations currently, but also delaying future revenue growth.  In such event
the market price of the USAT Common Stock is likely to drop, not only
discouraging the future exercises of USAT's warrants and options and possibly
discouraging potential new investors, but also increasing the risk that a
current investor in USAT may lose the value of his, her or its investment.

         U.S. Drug will require additional capital of $4,500,000 to $5,000,000
in order to complete the development of its drug testing products.  The
foregoing estimate does not include the estimated expenses of $2,000,000 to
$2,500,000 for manufacturing line start-up expenses relating to the chemistry
aspects of the product assuming that the development program is completed, as
to which there can be no assurance.  If the feasibility study currently being
conducted as to the product indicates that further development projects should
be abandoned, then U.S.  Drug's cash requirements will be substantially
reduced, but its future prospects for revenues will disappear.  Assuming that
the feasibility study results in a favorable conclusion and, if the Merger is
not consummated, there can be no assurance that U.S. Drug will be able to raise
the capital amounts based on selling only its own U.S. Drug Common Stock and
any such equity financings, if successfully implemented, will dilute the stock
ownership and voting rights of the current stockholders of U.S. Drug, including
USAT.  In addition, U.S. Drug may seek a major company to assist in certain
product development work and to fund such a product development program.
Depending on the financial arrangements to be negotiated, such development
partner may seek marketing rights with respect to the products when and if
successfully developed.  Because of the stage of development of the product and
the fact that no search or negotiations are currently being conducted, there
can be no assurance as to when and if any such marketing and/or product
development partner, if obtained, would make such an advance.  Were U.S. Drug
not to succeed in these efforts, its sublicense from USAT of the rights to the
USN technology would revert to USAT.  See "The Merger and Related
Matters-Reasons for the Merger," "The Company's Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "U.S. Drug's
Management's Discussion and Analysis of Financial Condition and Results of
Operations."

         4.      Competition.  The Company has a variety of competitors
depending on the particular aspect of its business, many of which have far
greater financial resources and marketing staffs than the Company.  There can
be no assurance that USAT will be able to
    





                                       26
<PAGE>   32
compete successfully with these companies.  See "Business of the
Company-Competition."

         Alcohol Testing

         The alcohol detection equipment industry is highly competitive.
Although management believes that USAT's Alco- Analyzer 2100 is the only
Department of Transportation approved evidential alcohol breath testing
instrument utilizing gas chromatography, it still competes with other alcohol
detection techniques developed by other companies.  USAT competes with other
small companies such as CMI Inc., Intoximeters, Inc.  and Lifeloc, Inc., which
also offer alcohol testing equipment.  Although all of these competitors are
believed currently to have greater revenues than USAT from sales of alcohol
testing devices, management is of the opinion that only CMI, Inc., which is a
subsidiary of MPD/MPH, may have greater financial resources than USAT.  In
addition, several companies, including Hoffman-LaRoche, Inc. ("Roche") and STC,
Inc., offer an on-site screening saliva based alcohol test.  Roche has, and
several of these other companies may have, greater revenues and financial
resources than the Company.

         Drug Testing

   
         The Company has not received any revenues from U.S. Drug because its
products are still in the developmental stage.  Currently U.S.  Drug is
developing two products which will screen for the presence of drugs of abuse,
one which will utilize flow immunosensor technology with urine samples as a
medium of testing and another which will utilize flow immunosensor technology
with saliva samples as a medium of testing.  U.S. Drug will compete with many
companies which currently utilize urine samples as a medium of testing, such as
Syva (a division of Syntex Corporation ("Syva"), Roche, Marion Laboratories,
Inc. ("Marion"), Abbott Laboratories, Inc. ("Abbot"), Editek, Inc. ("Editek"),
Hycor Biomedical, Inc. ("Hycor"), Princeton Bio Meditech, Inc. ("Princeton")
and Biosite, Inc. ("Biosite"), major pharmaceutical companies which also
provide substance abuse screening methods.  Currently, to management's
knowledge, no competitor is offering a saliva based testing product on an "on
site" basis for drugs of abuse.  However, management has been advised that one
or more companies may have such product under development and, accordingly,
there can be no assurance that a competitor will not offer such a product in
the future.  Even if no such product is offered, U.S. Drug anticipates
competition from other substance abuse detection methods provided by the major
companies mentioned in this paragraph.  If U.S. Drug successfully completes
development of first its saliva sample testing method and second its urine
sample testing method, as to which there can be no assurance, it is not certain
whether U.S. Drug will have the financial resources to compete successfully
with other companies
    





                                       27

which have greater financial resources available to them without the assistance
of a major pharmaceutical or other company possessing such resources.  There
can be no assurance that the assistance of such a company can be obtained,
especially because none is currently being sought.  In addition, U.S. Drug's
delay in bringing a drug testing product to market may adversely affect its
future marketing efforts because of the name recognition gained by competitors
actively marketing a product during this interim period.
    

         Human Resource Provider Operations

   
         ProActive is a single source service provider, meaning that it is a
provider of both substance abuse testing services and background screening
services.  A single source service provider is a relatively new concept.
Additionally, the Company, through the acquisition in May 1996 of RSA, can also
provide customized loss prevention services specifically designed to reduce the
negative effect of workplace substance abuse.  The competition from single
source providers which ProActive currently encounters is primarily from small
local and regional companies.  To management's knowledge, currently there is no
single source provider on a national level, which is what ProActive hopes to
become, and there are no other providers of customized programs and policies
like RSA.  However, Lab Corp., through Med-Express, is currently offering
background screening services to corporations on a limited basis.  Although,
ProActive has experienced personnel in both the drug testing and investigative
arena, there is no assurance that ProActive will become successful in marketing
its services as a single source provider on a national level.  In addition,
ProActive will face competition from other companies which provide each of
these services separately such as the companies mentioned in the preceding
subsections of this section "Competition" under this caption "Business of the
Company" as it relates to substance abuse testing providers (including the
laboratories which are vendors to ProActive), and local or regional
investigative firms or private investigators (including vendors to ProActive)
as it relates to background investigative services.  Assuming that the combined
RSA/ProActive operations achieve national status as a single source provider,
there can be no assurance that existing or new companies will not enter the
national marketplace to compete with the combined RSA/ProActive operations.
    

         5.  No Common Stock Dividends.  USAT has not paid any cash dividends
on the USAT Common Stock and, based on the Company's cash requirements and
continuing losses, does not anticipate paying cash dividends on the USAT Common
Stock in the foreseeable future.  See "The Merger and Related Matters-Summary
of the Terms of the USAT Common Stock-Dividends."

         6.  Depressive Effect on Market of Warrant or Option Exercises,
Potential 144 Sales and Untimely Sales by Selling Securityholders.  Any
exercise of the outstanding Common Stock purchase warrants or stock options of
USAT will increase the shares available for public trading, which may depress
the public market price for the USAT Common Stock.  USAT is required to
maintain a current prospectus in order to permit the sale of shares underlying
certain of USAT's warrants and USAT's options for any holder thereof who
exercises.  As of the date hereof, there was, in the opinion of counsel to
USAT, no such prospectus complying with Section 10(a)(3) of the Securities Act
and USAT was in the process of effecting filings under the Securities Act to
secure such a prospectus.  Accordingly, because the last of these USAT warrants
and USAT options do not expire until August 1, 2004, the potential exercises
and the subsequent sales thereof may act as an overhang on the market for the
USAT Common Stock for a long period.

         As of July 12, 1996, 35,337,335 shares of the USAT Common Stock were
issued and outstanding, of which 2,173,474 were held by current or former
directors and executive officers of USAT and could only be sold pursuant to
Rule 144 or another exemption under the Securities Act.  Essentially, Rule 144
permits the sale of (a) restricted securities (as such term is defined in Rule
144(a)(3)) held by any person after a two-year holding period and (b)
non-restricted securities held by affiliates of the issuer without any holding
period, in brokerage transactions and in an amount equal to the greater of the
average weekly reported trading volume during the prior four-week period or one
percent of the issuer's outstanding common shares during any three-month
period.  If the stockholder has held the restricted securities for more than
three years and has not been an affiliate for more than three months prior to
the contemplated sale (the term "affiliate" being generally defined as a
director, executive officer or a beneficial owner of such number of the
outstanding shares of the USAT Common Stock as to be deemed to be in control of
USAT), such stockholder may sell pursuant to Rule 144(k) under the Securities
Act without regard to such a limitation on the number of shares.

         As of July 12, 1996, there were also reserved for issuance: (a)
250,000 shares of the USAT Common Stock issuable upon the exercise at $1.33 per
share of a Common Stock purchase warrant expiring September 1, 1996; (b)
1,353,224 shares issuable upon the exercise at exercise prices ranging between
$1.33 and $4.00 per share of Common Stock purchase warrants expiring between
September 1, 1996 and December 17, 1997; (c) 61,250 shares issuable upon the
exercise at exercise prices ranging between $1.0625 and $4.00 per share of
Common Stock purchase warrants expiring between May 17, 1997 and September 1,
1998; (d) 82,750 shares issuable upon the exercise at exercise prices ranging
between $2.00 and $2.50 per share of Common Stock purchase

warrants expiring between September 1, 1998 and July 19, 1999; (e) 2,000,000
shares issuable upon the exercise at $2.00 per share of Common Stock purchase
warrants expiring December 17, 1999; (f) 185,207 shares issuable upon the
conversion of the shares of the Class A Preferred Stock, $.01 par value (the
"Class A Preferred Stock"); (g) 437,500 shares issuable upon the exercise at
$2.375 per share of the outstanding stock options originally expiring August 1,
2004, but now expiring the later of (i) 30 days after the effective date of a
post-effective amendment to a registration statement under the Securities Act
relating to the underlying shares of the USAT Common Stock or (ii) 90 days
after (1) the optionee's employment terminated or terminates or (2), if the
optionee is not an employee, the directorship terminated, granted under USAT's
1990 Restricted Stock, Non-Qualified and Incentive Stock Option Plan (the "1990
Option Plan"); (h) 60,000 shares issuable upon the exercise at $1.9375 per
share of Common Stock purchase warrants expiring November 15, 1998 issued to
new directors of USAT and a consultant; (i) 700,000 shares issuable upon the
exercise of three Common Stock purchase warrants expiring November 15, 1998 (as
to 400,000 shares at $1.9375 per share), November 15, 2000 (as to 150,000
shares at $3.00 per share) and November 15, 2000 (as to 150,000 shares at $4.00
per share) issued to a director in connection with his services in a capacity
other than as a director, including those related to the then pending private
placement pursuant to Regulation D under the Securities Act; (j) 300,000 shares
issuable upon the exercise at $3.125 per share of a Common Stock purchase
warrant expiring April 17, 1999 issued to the same director for other services
not in his capacity as a director; (k) 41,000 shares issuable upon the exercise
at exercise prices ranging between $1.875 and $2.8175 per share of Common Stock
purchase warrants expiring between July 17, 1998 and July 19, 1999 issued to
employees of the Company; (l) 200,000 shares issuable upon the exercise at
$2.00 per share of a Common Stock purchase warrant expiring December 27, 1998
issued to a then consultant to USAT for his acting as spokesperson for the
Company's alcohol and drug testing operations (on April 18, 1996 he was named
Chairman of the Board, Chief Executive Officer and a director of USAT); (m)
200,000 shares issuable upon the exercise at $2.00 per share of a Common Stock
purchase warrant expiring March 31, 1999 issued to RSA as a consultant to
ProActive in consideration of its services rendered to ProActive operations
(the warrant being divided among the RSA shareholders after the acquisition of
RSA by USAT); (n) 900,000 shares issuable upon the exercise at $3.125 per share
of Common Stock purchase warrants expiring May 20, 1999 issued to the RSA
shareholders as part of the RSA purchase price; (o) 600,000 shares issuable
upon the exercise at $3.125 per share of a Common Stock purchase warrant
expiring May 12, 1999 issued to the new President and Chief Operating Officer
of USAT; (p) 700,000 shares issuable upon the exercise at $2.4375 per share of
a Common Stock purchase warrant expiring February 26, 1999 issued to a
consultant to USAT for
    





                                       30
<PAGE>   36
   
financial public relations services; (q) 100,000 shares issuable upon the
exercise at $2.17 per share of Common Stock purchase warrants expiring October
19, 2000 issued to the placement agents for a private placement pursuant to
Regulation S under the Securities Act; and (r) 150,000 shares issuable upon the
exercise at $2.25 per share of a Common Stock purchase warrant expiring January
29, 2000 issued to an individual in connection with settlement of a litigation
against USAT.  The shares of the USAT Common Stock issuable upon the exercise
of the warrants and options described in subparagraphs (a), (b), (c), (d) and
(g) have all been registered under the Securities Act for resale by the holders
thereof;  however, there is not currently in effect a prospectus complying with
Section 10(a)(3) of the Securities Act that would permit resale of such
2,184,724 shares of the USAT Common Stock.  The 5,951,000 underlying shares for
the other warrants have to be registered under the Securities Act for either
issuance by USAT or resale by the holders.  All of the foregoing Common Stock
purchase warrants and options were granted at or above the fair market value of
the USAT Common Stock on the respective date of grant.  Were all of these
8,135,724 shares issuable upon the exercises of the foregoing USAT Common Stock
purchase warrants and stock options, assuming that the shares were made subject
to a prospectus complying with Section 10(a)(3) of the Securities Act
permitting their resale, the 185,207 shares issuable upon the conversion of the
Class A Preferred Stock, and the shares described in the preceding paragraph
which could be sold pursuant to Rule 144, or a substantial number of the
foregoing shares, publicly sold over a short time period, the market price of
the Common Stock could decline significantly because the market might lack the
capacity to absorb a large number of shares during a brief period.  Such a
decline in market price may make the terms of any future financing more
difficult for USAT to consummate on a favorable basis.

         In addition to its intention to register under the Securities Act the
5,951,000 underlying shares of the USAT Common Stock issuable upon the exercise
of the Common Stock purchase warrants and stock options described in the
preceding paragraph, either for issuance by USAT or for resale by the holders,
as to many of whom USAT has given a registration commitment, USAT has also
given a registration commitment to the purchasers of 2,000,000 shares of the
USAT Common Stock issued in the private placement as to which the final closing
was held on February 14, 1996 and to the former RSA shareholders for the
500,000 shares of the USAT Common Stock they received upon the acquisition of
RSA by USAT.  The 500,000 shares issued to the RSA shareholders were registered
under the Securities Act as "Acquisition Shares" in USAT's Registration
Statement on Form S-1, File No. 33-43337 (the "January 1992 Registration
Statement"), but may require a post-effective amendment to the January 1992
Registration Statement being declared effective under the Securities Act for
such shareholders to resell.  See "The Merger and Related Matters-

Summary of the Terms of the USAT Common Stock-Acquisition Shares."  Were these
2,500,000 shares of the USAT Common Stock registered under the Securities Act
for resale by the holders and, if a substantial number of these shares were
offered for sale at the same time, such offerings could have the same adverse
impact as described in the preceding paragraph.

         To the extent that the Merger is consummated, an aggregate of _____
shares of the USAT Common Stock will be issued to the U.S. Drug Minority
Stockholders.  To the extent that the Good Ideas Merger is consummated, an
aggregate of _____ shares of the USAT Common Stock will be issued to the
minority stockholders of Good Ideas.  The aggregate of _________ shares of the
USAT Common Stock issued on such transactions will, with limited exceptions, be
freely tradeable and, if a substantial number of these shares were offered for
sale at the same time, such offerings could have the same impact as described
in the second preceding paragraph.

         7.  Technological Changes.  The substance abuse testing industry is a
technological sensitive industry in that companies are constantly developing
new methods and making changes to current methods for substance abuse detection
in order to remain competitive.  USAT competes, and, when its development stage
for a saliva based test and a urine based test are completed, U.S. Drug will
compete, with larger companies such as those named under "Business of the
Company-Competition," many of which have substantially greater financial
resources available to them to invest in the research and development of their
products than USAT and U.S. Drug.  These competitors may develop products in
the future which may render USAT's and U.S. Drug's products obsolete or
non-competitive from a pricing point of view.  To remain competitive, USAT and
U.S. Drug may require substantial financial resources for personnel and other
costs to conduct research and update current products to reflect the
technological advances; however, such financial resources may not be available.
In the alternative, depending on the progress in the drug testing research and
development program (including the current feasibility study), U.S. Drug may at
a later date seek a major pharmaceutical or other company to assist in the
development program and, depending on the financial arrangements to be
negotiated, such development partner may seek marketing rights to the products
when and if successfully developed.  Although such a partner may reduce certain
current expenditures, it may later, by assuming marketing rights, reduce
prospective revenues to U.S. Drug.  Because of the stage of development of the
product and the fact that no search or negotiations are currently being
conducted, management believes that it is currently too speculative to
anticipate U.S. Drug's competitive position based on the presence of a
development and/or marketing partner.  See the section "Need for Financing"
under this caption "Risk Factors" and "Business of the Company-Competition."
    





                                       32
<PAGE>   38
   
         8.  Market Limitation for Alcohol Testing Products.  The potential
markets for USAT's alcohol testing products may be substantially limited to the
ones in which it currently sells - law enforcement, correctional facilities,
medical and clinical facilities, alcohol treatment centers and emergency rooms.
This market insofar as alcohol testing is concerned may be saturated and the
opportunity for growth limited; however, management of USAT believes that the
demand for alcohol testing could grow in the industrial market, in which USAT
does some current selling, on a broader basis as did the demand for drug
testing at an earlier date.  There can be no assurance that such growth will
occur or that, if the growth occurs, USAT will successfully penetrate the
industrial market.  See the sections "Marketing" and "Competition" under the
caption "Business of the Company."

         9.  Other Conflicts of Interest.  From January 1992 to January 1993,
prior to the transfer by USAT to U.S. Drug of USAT's license interest to the
USN technology, USAT conducted U.S. Drug's business operations and, in the
event of a default by U.S. Drug, its sublicensee rights would revert to USAT as
licensee.  Since April 1, 1993, USAT has been managing certain of U.S. Drug's
operations pursuant to a management agreement.  As of June 30, 1996, 67.0% of
the outstanding shares of the U.S. Drug Common Stock were held by USAT.  As of
March 31, 1996, there were notes receivable from USAT to U.S. Drug in the
amount of $282,295 which, as extended, were due June 30, 1996.  The
indebtedness was repaid and USAT has authorized a loan of $500,000 to U.S. Drug
which amount will be due December 31, 1996.  For additional information as to
the relationships between USAT and U.S. Drug, see the section "USAT
Affiliations of U.S. Drug Directors" under this caption "Risk Factors;"
"Material Contacts of USAT with U.S. Drug;" "USAT Principal Stockholders;"
"U.S. Drug Principal Stockholders;" and "USAT Management".

         10.     Loss of Direct Ownership of U.S. Drug.  If the Merger is
consummated, the U.S. Drug Minority Stockholders will lose their direct,
although minority, ownership interest in U.S. Drug.  As a result, to the extent
any U.S. Drug Minority Stockholder wanted to be an investor solely in a drug
testing company, such stockholder would lose such opportunity as the result of
the Merger.
    


                            TERMS OF THE TRANSACTION

CONSENT SOLICITATION STATEMENT/PROSPECTUS

         This Consent Solicitation Statement/Prospectus is being furnished to
the U.S. Drug Minority Stockholders for the purpose set forth in the next
paragraph and to offer the shares of the USAT Common Stock necessary to
consummate the Merger (see the subsection "The Merger" under this caption
"Terms of the





                                       33
<PAGE>   39
Transaction").  On the Record Date, there were ___ holders of record of the
U.S. Drug Minority Common Stock.

   
         Pursuant to this Consent Solicitation Statement/Prospectus, the U.S.
Drug Minority Stockholders are being requested to consent to a proposal to
adopt the Merger Agreement, a copy of which is attached hereto as Appendix A
and is incorporated into this Consent Solicitation Statement/Prospectus by this
reference, providing for the merger of U.S. Drug with and into Acquisition
Corp. (i.e., the Merger), the conversion of shares of the Minority U.S. Drug
Common Stock into shares of the USAT Common Stock on the basis set forth in the
Merger Agreement and the conversion of the U.S. Drug Warrants to acquire U.S.
Drug Common Stock into equivalent USAT Merger Warrants adjusted for the
exchange rate set forth in the Merger Agreement.  The U.S. Drug Options will
either be cancelled with the holders' consent or must, by their terms, be
exercised prior to the Merger.  The U.S. Drug Minority Stockholders will also
receive Rights entitling them to share in cash payments, if any, by a
development partner to the extent that such partner seeks marketing rights in
return for immediate payments to Acquisition Corp. or USAT within one year of
the Effective Date.  However, there can be no assurance that such a partner
will be obtained on a timely basis, that it would make any such cash payment
and when such payment would be made.  See the section "Special Payment" under
this caption "Terms of the Transaction" and the sections "Terms of the Merger
Agreement-Conversion of Shares" and "U.S. Drug Options and Warrants" under the
caption "The Merger and Related Matters" for more detailed information.
    


THE MERGER

   
         Pursuant to the Merger Agreement, at the Effective Date, each
outstanding share of the U.S. Drug Common Stock, other than the shares owned by
USAT, will be converted into ______ shares of the USAT Common Stock.  Each
share of the U.S. Drug Common Stock owned by USAT will be canceled upon the
Merger.  The number of shares of the USAT Common Stock to be received for each
share of the Minority U.S. Drug Common Stock was determined by dividing $5.25
by the average of the closing sales prices per share of the USAT Common Stock
as reported on the American Stock Exchange during the 30 days prior to the
Record Date, which average sales price per share was $_________.  An aggregate
of _______ shares of the USAT Common Stock will be issued to the U.S. Drug
Minority Stockholders, subject to adjustment for fractional shares.  Prior to
the Merger, USAT owned 67.0% of U.S. Drug; after the Merger, USAT will own 100%
of Acquisition Corp. as the successor by merger to U.S. Drug.  Assuming that
there are no exercises of outstanding Common Stock purchase warrants or stock
options or any conversions of USAT preferred stock between the date of this
Consent Solicitation Statement/Prospectus and the Effective Date,
    





                                       34
<PAGE>   40
   
the USAT stockholders will own ____% of the outstanding shares of the USAT
Common Stock and the U.S. Drug Minority Stockholders will own _____%.  See "The
Merger and Related Matters".
    

         If the Merger is not consummated, U.S. Drug and USAT will continue to
be publicly-owned companies and U.S. Drug will continue to be a majority-owned
subsidiary of USAT.


SPECIAL PAYMENT

   
         U.S. Drug may at a later date seek a major company to assist in the
development of its saliva based testing products.  Some of the criteria for
such a company would be that: (1) the company is unaffiliated with USAT; (2)
the company is well established and recognized in the substance abuse testing
products industry; and (3) the company has substantial development and
marketing experience in the substance abuse testing products industry.  If the
feasibility study as to the saliva based testing product currently being
conducted by U.S. Drug indicates further development is desirable, the Company
can, as an alternative to 100% internal development, seek to have a major
company help in the development program, which would reduce current
expenditures, but would also reduce future revenues to the extent marketing
rights are demanded by such development partner.  USAT has agreed in the Merger
Agreement that, if a definitive agreement (the "Development and Marketing
Agreement") with such a partner is executed and if such a partner makes a cash
payment or payments upon the execution of the Development and Marketing
Agreement (the "Special Payment") to Acquisition Corp. or USAT, then USAT will
calculate the percentage (to the nearest tenth) that the outstanding shares of
the Minority U.S. Drug Common Stock on the Effective Date constitute of the
outstanding shares of the U.S. Drug Common Stock on the Effective Date,
multiply such percentage by the amount of the Special Payment (the "Minority
Stockholders' Special Payment Interest") and (1) if the Development and
Marketing Agreement is entered into on or prior to the 180th day following the
Effective Date, USAT will pay to each of the former U.S. Drug Minority
Stockholders his, her or its pro rata share of one third of the Minority
Stockholders' Special Payment Interest; (2) if the Development and Marketing
Agreement is entered into during the period after the 180th day following the
Effective Date and on or prior to the first anniversary of the Effective Date,
USAT will pay to each of the former U.S. Drug Minority Stockholders his, her or
its pro rata share of one sixth of the Minority Stockholders' Special Payment
Interest; and (3) if the Development and Marketing Agreement is entered into
after the first anniversary of the Effective Date, the former U.S. Drug
Minority Stockholders will receive none of the Special Payment.

         If a cash payment is received from the partner after execution, but on
or prior to the first anniversary of the
    





                                       35
<PAGE>   41
   
Effective Date, and if such payment is not based on sales effected by the
partner, which sales are not currently anticipated because of the anticipated
product development timetable,  or some other performance based criteria such
as the number of drug tests conducted or the successful development of assays
by such partner, then USAT will treat any such payments as if received on the
execution of the Development and Marketing Agreement (i.e., to be an
installment of the Special Payment).  As discussed above, any such payments
would reduce the revenues of the Company.  Loans made by the development
partner will not be deemed to be part of the Special Payment, as would equity
infusions for which the development partner receives shares of the USAT Common
Stock or some other security from the Company.

         The following are examples of how the formula would work in each
period: Assuming that there is no change from the Record Date, the 1,721,900
shares of the Minority U.S. Drug Common Stock constitute approximately 33.0% of
the 5,221,900 shares of the U.S. Drug Common Stock and assuming that there is a
Special Payment of $10,000,000 to Acquisition Corp. by the development partner,
then (1) if the Development and Marketing Agreement is entered into during the
initial 180 days, the U.S. Drug Minority Stockholders would receive an
aggregate of approximately one-third of 33% of $10,000,000 or an aggregate of
approximately $1,100,000 (i.e., 11% of $10,000,000 or $.64 per share); (2) if
the Development and Marketing Agreement is entered into during the period after
the 180th day following the Effective Date and on or prior to the first
anniversary of the Effective Date, the U.S. Drug Minority Stockholders would
receive an aggregate of approximately one-sixth of 33% of $10,000,000 or an
aggregate of approximately $550,000 (i.e., 5.5% of $10,000,000 or $.32 per
share); and (3) if the Development and Marketing Agreement is entered into
thereafter, Acquisition Corp. will retain the entire $10,000,000.

         The Right to share in the Special Payment is not transferable.  A
transferee of the shares of the USAT Common Stock received as a result of the
Merger is not eligible to receive a proportionate share of the Special Payment
and USAT will make such payments only to the U.S.  Drug Minority Stockholders
as reflected on the stock books of U.S. Drug on the Effective Date or, in the
event of the death of the U.S. Drug Minority Stockholder, his or her heirs or
legal representatives, in the case of the dissolution of a partnership, to its
partners or, in the case of a corporation, to its successor by merger or other
operation of law.  Further, the Right to share in the Special Payment cannot be
pledged.

         In providing for the Special Payment on February 26, 1996, the USAT
Board sought to respond to comments of certain U.S. Drug Minority Stockholders
that the Merger would deprive them of the benefits of what they anticipate
would be a large initial payment
    





                                       36

from a development partner.  However, the USAT Board believed that both the
amount and timing should be limited because (1) even if the Merger were not
consummated and the Special Payment were received, the U.S. Drug Board would
not be authorizing a cash dividend to the U.S. Drug stockholders of the Special
Payment, but would use the Special Payment instead for operations, and (2)
because USAT's post-Merger level of investment in Acquisition Corp. will
probably increase, with the passing of each month following the Effective Date,
USAT stockholders will increasingly anticipate that any distributions
attributable to Acquisition Corp.'s operations should benefit all of the USAT
stockholders, not just the former U.S. Drug Minority Stockholders, many of whom
may have sold their shares of the USAT Common Stock at the time of the Special
Payment.  The USAT Board took note of the fact that, if there were no Merger,
the public announcement of the addition of a development partner for U.S. Drug
would possibly give rise to an increase in the market price of the U.S. Drug
Common Stock, so that a U.S. Drug Minority Stockholder might benefit by a sale
of his, her or its shares of the Minority U.S. Drug Common Stock at such higher
price.  However, the USAT Board concluded that it was too speculative to make
its decision on the basis of speculation as to what might be the future market
value of the U.S. Drug Common Stock in view of the possibilities that no drug
test product may be developed, that no development partner may be obtained
during the next year, that, even if such a partner was obtained, it may not
make a significant advance payment and that competitors may introduce a saliva
based drug testing product in the interim period.  See also "The Merger and
Related Matters-Reasons for the Merger and Approval."

         As of the date hereof, U.S. Drug has not commenced negotiations or
entered into any agreement with a development and/or marketing partner, nor
does it have any basis for evaluating what the amount of the Special Payment,
if it is to be made, will be.  There can be, accordingly, no assurance that
U.S. Drug will enter into a marketing arrangement with a partner within the
time frame set forth in the Merger Agreement or, if it does, that the partner
will make any cash payment to Acquisition Corp. or USAT upon execution of the
Development and Marketing Agreement.  Due to the highly speculative nature of
the Special Payment, the Boards of Directors of both USAT and U.S. Drug have
urged the U.S. Drug Minority Stockholders not to base their consent to the
Merger on the likelihood of there being a Special Payment.  In addition,
because of the speculative nature, the Special Payment will be treated as a
contingent liability to former stockholders for accounting purposes until
disbursed.  Accordingly, Whale Securities, in conducting its analyses, did not
place any value on the Right of a U.S.  Drug Minority Stockholder to receive
such a payment.

VOTING RIGHTS

   
         The Record Date for the determination of the stockholders of U.S. Drug
entitled to notice of the consent solicitation and to consent hereunder is
August __, 1996 as fixed by the Board of Directors of U.S. Drug on August __,
1996 pursuant to Section 213(b) of the GCL.

         On the Record Date, there were 5,221,900 shares of the U.S. Drug
Common Stock issued and outstanding, of which 3,500,000 shares (67.0%) were
owned by USAT and 1,721,900 shares (33.0%) by stockholders other than USAT
(i.e., the U.S. Drug Minority Stockholders).  See "U.S. Drug Principal
Stockholders" for information, as of the Record Date, regarding persons known
by U.S. Drug to own beneficially 5% or more of the U.S.  Drug Common Stock, of
which the only person is USAT, and as to the stock ownership of directors and
executive officers of U.S. Drug.  Each share of the Minority U.S. Drug Common
Stock is entitled to one vote.  Although, under Section 251 of the GCL, USAT,
as the majority stockholder of U.S. Drug, could adopt the Merger Agreement
without the consent of any other U.S. Drug stockholder, the Boards of Directors
of USAT and U.S. Drug have agreed that, as a condition to the adoption of the
Merger Agreement, the affirmative consent of the holders of at least 50% of the
outstanding shares of the U.S. Drug Common Stock owned by stockholders other
than USAT is required for the adoption of the Merger Agreement.  Holders of the
Minority U.S. Drug Common Stock are not entitled to dissenters rights under the
GCL as to the vote with respect to the adoption of the Merger Agreement.  See
the section "The Consent Procedure-Rights of Dissenting U.S. Drug Shareholders"
under this caption "Terms of the Transaction."
    

THE CONSENT PROCEDURE

(1)  STATUTORY BASIS

         Unless a corporation's certificate of incorporation otherwise
provides, Section 228 of the Delaware General Corporation Law (the "GCL")
permits stockholders' actions without a meeting of stockholders and without
prior notice if a consent or consents in writing, setting forth the action so
taken, is signed by the holders of the outstanding shares of the voting stock
having not less than the minimum number of votes that would be necessary to
take such action at a meeting at which all shares entitled to vote thereon were
present.  U.S. Drug's certificate of incorporation does not otherwise provide,
so that a consent procedure pursuant to Section 228 of the GCL may be utilized
by USAT.  Under the applicable provision of the GCL, such action is effective
when written consents from holders of record of the minimum number of
outstanding shares of the voting stock necessary to authorize the action are
executed and delivered to the corporation within 60 days of the earliest dated
consent





                                       38
<PAGE>   44
delivered in accordance with the GCL to the corporation.  Under Section 251 of
the GCL, a domestic corporation may be merged with and into another domestic
corporation by the affirmative vote of the record holders of more than 50% of
the outstanding shares of the voting stock acting without a meeting and without
prior notice.  Accordingly, USAT as the owner of 67.0% of the U.S. Drug Common
Stock could adopt the Merger Agreement without any other stockholder voting in
favor of the adoption of the Merger Agreement.  Notwithstanding the foregoing,
the Merger Agreement provides that it is a condition to the consummation of the
Merger that the record holders of more than 50% of the outstanding shares of
the U.S. Drug Common Stock owned by U.S. Drug stockholders other than USAT
(i.e., the U.S. Drug Minority Stockholders) consent to the adoption of the
Merger Agreement.  USAT will execute and deliver a consent to the adoption of
the Merger Agreement as a stockholder of U.S.  Drug only after the holders of
more than 50% of the outstanding shares of the Minority U.S. Drug Common Stock
have consented in order to permit the filing of a Certificate of Merger in
Delaware pursuant to the GCL and the terms of the Merger Agreement.  USAT and
U.S. Drug have agreed not to waive the requirement as to the approval by the
U.S. Drug Minority Stockholders of the Merger Agreement and USAT has agreed not
to execute and deliver its consent to the adoption of the Merger Agreement if
such approval is not obtained.

(2)  PROCEDURE TO CONSENT

         UNDER THE GCL, ONLY HOLDERS OF RECORD ON THE RECORD DATE ARE ELIGIBLE
TO GIVE THEIR CONSENT TO THE ADOPTION OF THE MERGER AGREEMENT.  ANYONE OWNING
SHARES BENEFICIALLY (BUT NOT OF RECORD), SUCH AS A PERSON WHOSE OWNERSHIP OF
SHARES IS THROUGH A BROKER, BANK OR OTHER FINANCIAL INSTITUTION, WHO WISHES TO
GIVE THEIR CONSENT SHOULD CONTACT THAT BROKER, BANK OR FINANCIAL INSTITUTION
WITH INSTRUCTIONS TO EXECUTE THE WHITE FORM OF CONSENT ON HIS OR HER BEHALF OR
TO HAVE THE BROKER, BANK OR FINANCIAL INSTITUTION'S NOMINEE EXECUTE THE
CONSENT.

         USAT is soliciting the written consents referred to herein and, if
stockholders wish to give their consent, the white consent card should be
returned to Georgeson & Company Inc., Wall Street Plaza, New York, New York
10005, in the enclosed envelope, or to U.S. Drug Testing, Inc., 10410 Trademark
Street, Rancho Cucamonga, California 91730, Attention: Secretary.

(3)  REVOCATION

         An executed consent card may be revoked at any time before expiration
by marking, dating, signing and delivering a written revocation before the time
that sufficient unrevoked consents have been received to authorize the action
for which consents are solicited.  Consents must be received within 60 days
after the





                                       39
<PAGE>   45
first consent is delivered to U.S. Drug.  A revocation may be in any written
form validly signed by the record holder as long as it clearly states that the
consent previously given is no longer effective.  The delivery of a
subsequently dated consent card which is properly completed will constitute a
revocation of any earlier consent.  The revocation may be delivered to
Georgeson & Company Inc., Wall Street Plaza, New York, New York 10005 or to
U.S. Drug Testing, Inc., 10410 Trademark Street, Rancho Cucamonga, California
91730, Attention: Secretary.

(4)  MISCELLANEOUS

         ABSTAINING FROM GIVING A CONSENT OR NOT RETURNING A SIGNED CONSENT
WILL HAVE THE SAME EFFECT AS WITHHOLDING CONSENT TO THE PROPOSED ACTION.  IF
YOU ARE THE STOCKHOLDER OF RECORD AND YOU WISH TO GIVE YOUR CONSENT, PLEASE
SIGN, DATE AND RETURN THE ENCLOSED WHITE CONSENT CARD PROMPTLY IN THE ENVELOPE
PROVIDED.

         IF YOUR SHARES OF THE U.S. DRUG COMMON STOCK ARE HELD IN THE NAME OF A
BROKERAGE FIRM, BANK OR NOMINEE, ONLY THEY CAN CONSENT TO THE PROPOSED ACTION
AND ONLY UPON RECEIPT OF YOUR SPECIFIC INSTRUCTIONS.  ACCORDINGLY, IF YOU WISH
TO GIVE YOUR CONSENT, PLEASE CONTACT THE PERSON RESPONSIBLE FOR YOUR ACCOUNT
AND GIVE INSTRUCTIONS FOR SUCH SHARES IMMEDIATELY.

         USAT will pay all of the costs and expenses in connection with the
preparation, printing and distribution of this Consent Solicitation
Statement/Prospectus, including, without limitation, attorneys' fees,
accounting fees and printing expenses, and all other expenses with respect to
the Merger and the related transactions except for the fees and expenses of
Whale Securities in delivering a fairness opinion for the benefit of the U.S.
Drug Minority Stockholders and the fees and disbursements of U.S. Drug's
special counsel.  U.S. Drug will pay a fee of $35,000 to Whale Securities for
such services, together with out-of-pocket expenses.  USAT has retained
Georgeson & Company Inc. to assist with the solicitation of consents from the
U.S. Drug Minority Stockholders, for which services Georgeson & Company Inc.
will receive a fee of $3,750, together with out-of-pocket expenses.  In
addition, the directors, officers and employees of USAT, who will receive no
additional compensation, will participate in the solicitations.  Consents may
be solicited by personal interviews, telephone calls and telegrams to
supplement the solicitation by mail.  Arrangements will also be made with
banks, brokerage houses and other custodians, nominees and fiduciaries for the
forwarding of consent solicitation materials to the beneficial owners of stock
held of record by such persons, and USAT will reimburse such custodians,
nominees and fiduciaries for reasonable out-of-pocket expenses incurred by them
in connection therewith.

<PAGE>   46
   
         Each of the current or former directors of U.S. Drug has advised U.S.
Drug that, except for Dr. William DiTuro, a former director, who owns 1,600
shares of the U.S. Drug Common Stock, and, as indicated in the succeeding
paragraph, Michael S. McCord, a director of U.S. Drug, he or she does not own
any shares of the Minority U.S. Drug Common Stock.  Three former directors of
U.S. Drug have advised USAT that he or she will surrender his or her U.S. Drug
Option, which Options represent the right to purchase an aggregate of 110,000
shares of the U.S. Drug Common Stock, if the Merger is consummated.  U.S. Drug
Options to purchase an aggregate of 10,000 shares held by Dr. DiTuro and Glenn
A.  Bergenfield, another former director of U.S. Drug, have expired.  Douglas
G. Allen, the President of U.S. Drug until July 31, 1996, and Steven Kline, a
Vice President of U.S. Drug, hold U.S. Drug Options to purchase an aggregate of
42,000 shares of the U.S. Drug Common Stock.  Pursuant to the terms thereof,
each such Option will, immediately prior to the consummation of the Merger,
become fully exercisable.  Because USAT has declined to assume these U.S. Drug
Options, they will expire if not exercised on or before the Effective Date.
Because of the higher exercise price (i.e., $7.00 per share) as compared with
USAT's offer to the U.S. Drug Minority Stockholders, USAT does not anticipate
any exercises of the U.S. Drug Options.

         Each of the directors and executive officers of USAT has advised USAT
that, except for Peter M. Mark who owns 15,500 shares of the Minority U.S. Drug
Common Stock, which Mr. Mark intends to submit a consent in favor of the
Merger, he or she does not own any shares of the Minority U.S. Drug Common
Stock.  Michael S. McCord, a director of U.S. Drug, a consultant to the USAT
Board of Directors and a former member of the Committee, has advised USAT that
he and persons who may be deemed his affiliates (as such term is defined in
Rule 405 under the Securities Act) own an aggregate of 61,300 shares of the
Minority U.S. Drug Common Stock and that each of these persons will submit a
consent in favor of the Merger.  James C. Witham and Karen B. Laustsen, who
were directors and executive officers of USAT until April 18, 1996, and Gary S.
Wolff, who was an executive officer of USAT until July 3, 1996, have advised
USAT that they are the U.S. Drug directors holding the U.S. Drug Options as
described in the preceding paragraph.

         The USAT Board has determined that USAT will not proceed with the
Merger unless USAT has received consents from the holders of at least 50% of
the outstanding shares of the Minority U.S. Drug Common Stock without including
Dr. DiTuro's 1,600 shares, Mr. Mark's 15,500 shares or the 61,300 shares of Mr.
McCord and persons who may be deemed his affiliates or an aggregate of 78,400
shares.  Accordingly, the consent of the holders of 860,951 shares of the
remaining 1,643,500 shares of the Minority U.S. Drug Common Stock or 52.4% of
thereof will be necessary to consummate the Merger.  If the Merger is
    





                                       41
<PAGE>   47
consummated, Dr. DiTuro and Messrs. Mark and McCord will receive shares of the
USAT Common Stock for their shares of the Minority U.S. Drug Common Stock on
the same basis as the other U.S. Drug Minority Stockholders and will have the
same right to share in the Special Payment (see the section "Special Payment"
under this caption "Terms of the Transaction").

(5)  RIGHTS OF DISSENTING U.S. DRUG STOCKHOLDERS

   
         Under Section 262(b) of the GCL, appraisal rights are not available to
holders of the Minority U.S. Drug Common Stock in connection with the
consummation of the Merger because both the USAT Common Stock which will be
received by the U.S. Drug Minority Stockholders and the U.S. Drug Common Stock
were listed on national securities exchanges as of the Record Date.
Additionally, Delaware counsel for USAT and U.S.  Drug has advised them that
U.S. Drug may not voluntarily offer, under Delaware law, its stockholders
appraisal rights.  Section 262 of the GCL specifies the circumstances in which
stockholders are entitled to appraisal rights.  Delaware courts have
consistently held that appraisal rights may only be granted by statute or by
corporate charter.  Because Section 262(b) bars appraisal rights to the U.S.
Drug Minority Stockholders as indicated above because of the listed status and
the U.S. Drug Certificate of Incorporation does not permit voluntary rights of
appraisal as allowed by Section 262(c) of the GCL, the U.S. Drug Minority
Stockholders may not be granted voluntary appraisal rights if the Merger is
approved.
    


                         THE MERGER AND RELATED MATTERS

REASONS FOR THE MERGER AND APPROVAL

   
(1) AUTHORIZATION

         On November 16, 1995, the Board of Directors of USAT approved in
principle the acquisition of the minority stockholder interest in U.S.  Drug
and, on February 6, 1996, authorized execution of the Merger Agreement, which
included an offer of a fraction of a share of the USAT Common Stock having a
value of $5.25 per share for each share of the U.S. Drug Minority Stock, the 
determination to be based on the average of the closing sales prices of the
USAT Common Stock during the 30 calendar days prior to the Record Date.  In
determining this exchange ratio, the USAT Board considered, based on an
application of the formula, a range as to the number of shares of the USAT
Common Stock to be issued to the U.S. Drug Minority Stockholder -- a maximum
above which the USAT Board would not want to proceed with the Merger because it
would, in the USAT Board's opinion, be unfair to the USAT stockholders and a
minimum below which the offer would probably be unacceptable to the U.S. Drug
Minority Stockholders.
    





                                       42
<PAGE>   48
   
         On April 23, 1996, the Board of Directors of U.S. Drug authorized
execution of, and submission to the U.S. Drug Minority Stockholders for
approval of, the Merger Agreement.  Also in making its determination as to the
exchange ratio, the U.S. Drug Board considered a range as to the number of
shares of the USAT Common Stock to be issued to the U.S. Drug Minority
Stockholder based on an allocation of the formula -- a minimum below which the
offer would be unacceptable to the U.S. Drug Board for offering the U.S. Drug
Minority Stockholders and a maximum above which the USAT Board would, in the
opinion of the U.S. Drug Board, reject as being unfair to the USAT
stockholders.  As of such date, there were three directors of U.S. Drug, none
of whom were employees of U.S. Drug, but all of whom were employees of USAT.
The directors were: James C. Witham and Karen B. Laustsen, each of whom was,
until his and her resignations on April 18, 1996, a director and an executive
officer of USAT, and Gary S. Wolff, who was an executive officer of USAT until
July 3, 1995 and a director of USAT until September 26, 1995.  All three
directors were also stockholders of USAT.  Ms. Laustsen resigned as a director
of U.S. Drug effective May 28, 1996; Mr. Witham resigned effective May 31,
1996; and Mr. Wolff resigned effective July 3, 1996.  The current U.S. Drug
Board was elected on May 31, 1996 and is made up of the following three
directors: Linda H. Masterson and Robert Stutman, who are directors, executive
officers and employees of USAT, and Michael S. McCord, who is a consultant to
the USAT Board of Directors and a former member of the Committee.  Each of the
foregoing is a securityholder of USAT.

         All actions taken by the Boards of Directors concerning the
authorization of the Merger Agreement and the transactions related thereto were
unanimously approved except that Ms. Laustsen abstained at the February 6, 1996
USAT Board meeting because of her concern of being on both sides of the
transaction.  However, when Ms. Laustsen voted as a U.S. Drug director on April
23, 1996 in favor, she said that she also supported the Merger as a USAT
director.  Despite the resignations of Messrs. Witham and Wolff and Ms.
Laustsen, each has advised USAT that he and she continue to support the Merger.
All of the new members of the U.S. Drug Board also support the Merger and the
USAT Board continues its unanimous support.

          On _________, 1996, after the number of shares to be offered to the
U.S. Drug Minority Stockholders was calculated pursuant to the exchange ratio,
both the USAT Board and the U.S. Drug Board concluded that the number of shares
was within the ranges each had previously considered.

          On February 6, 1996, USAT's Board, acting on behalf of USAT as the
sole stockholder of Acquisition Corp., adopted the Merger Agreement and, on
April 23, 1996, Acquisition Corp.'s Board of Directors, consisting of Alan I.
Goldman, John C. Lawn and Linda H. Masterson, who also serve as USAT directors
and, in Ms.
    





                                       43
<PAGE>   49
   
Masterson's case, since May 13, 1996, also as the President and Chief Operating
Officer of USAT, unanimously authorized execution of the Merger Agreement and
approved the related transactions.

(2)  ATTEMPTS TO RESOLVE CONFLICT OF INTERESTS

         As a result of the interlocking historical relationships among the
directors of U.S. Drug with USAT as described above, the U.S. Drug Board of
Directors has never been independent of USAT and all of the directors have owed
fiduciary duties to both USAT and U.S. Drug, creating a conflict of interest,
which has existed since USAT incorporated U.S. Drug in October 1992.  However,
specifically with respect to the Merger, the U.S. Drug Board approved certain
safeguards in an effort to assure fairness to the U.S. Drug Minority
Stockholders.  First, the Merger Agreement must be adopted by the holders of at
least 50% of the outstanding shares of the Minority U.S. Drug Common Stock
(excluding from such calculation the 78,400 shares in the aggregate held by
current and former directors of U.S. Drug and the affiliates of one director),
even though the consent of USAT alone is sufficient to adopt the Merger
Agreement in accordance with the GCL.  Second, a major firm was engaged as
independent counsel for U.S. Drug.  Lastly, the Board of Directors of U.S. Drug
has received an opinion from Whale Securities as to the fairness of the Merger
to the U.S. Drug Minority Stockholders from a financial point of view as of the
date of the opinion.  The Merger Agreement provides that the first and second
protection for the U.S. Drug Minority Stockholders cannot be waived by any
party.

         The USAT Board and the U.S. Drug Board each considered adding
independent directors to U.S. Drug, but rejected the idea because of what each
considered the virtual impossibility, especially in light of today's potential
director liability, of finding a person or persons to accept a directorship in
a public company knowing that it is in the process of going private and that
USAT has majority control of the U.S.  Drug Common Stock (68.5% of the
outstanding shares as of June 30, 1996 if the directors' and affiliates' shares
are included).  Although USAT could have attempted to cause U.S. Drug to make
it financially attractive for a potential director to accept a directorship,
both the USAT and U.S. Drug Boards believed that this would not be a prudent
use of Good Ideas' money and that any such payment or payments could be
perceived as a "bribe" to favor the Merger.

         The USAT Board and the U.S. Drug Board also considered engaging an
independent representative for U.S. Drug to negotiate the terms of the
transaction, but concluded that, in view of the above safeguards to be used,
the expenditure to engage such a person did not appear justified.  Because of
the extensive amounts required by U.S. Drug to complete its product development
program, with no assurance that marketable products would be

    

                                       44
<PAGE>   50
   
developed, the Boards concluded that U.S. Drug's operations did not warrant
devoting a substantial amount of time and money to effecting a "taking private"
proposal by engaging an independent negotiator as opposed to using the limited
funds to meeting operational requirements and adopting the safeguards described
in the second preceding paragraph.

(3) DETERMINATION OF TERMS

         Commencing in October 1995, there were a series of meetings, including
those enumerated under the subsection "Authorization," at which either the USAT
directors or the U.S. Drug directors discussed the concept of taking U.S. Drug
private and ultimately set the terms therefor, including the exchange ratio and
using the mechanism of a merger rather than a tender offer.  James C. Witham
and Karen B. Laustsen, who sat on both Boards and were in contact with certain
of the U.S. Drug Minority Stockholders, and Michael S. McCord, who was a
consultant to the USAT Board and a stockholder in both USAT and U.S. Drug,
advised the other directors as to the concerns expressed by certain minority
stockholders to them.

         Representatives of Rosenman & Colin, LLP, special counsel to U.S.
Drug, met with the U.S. Drug directors on several occasions, advising them
about their fiduciary duties, complicated by the fact, as indicated above in
the subsection "Authorization" under this caption, that all had dual
responsibilities to U.S. Drug and USAT.  Similarly Gold & Wachtel, LLP, general
counsel to USAT, advised the USAT directors at several meetings about their
fiduciary duties.  Both counsel responded to questions about the applicability
of the business judgment rule to the proposed transaction.

         Commencing in November a representative of Whale Securities met with
members of the U.S. Drug Board on several occasions first to review the factors
to be considered in determining whether a USAT offer would be fair and, once
the exchange ratio was determined, the reasons why Whale Securities considered
the USAT exchange ratio to be fair to the U.S. Drug Minority Stockholders.  On
May 20, 1996, the USAT directors met with such representative to review the
preliminary fairness opinion.

(4) USAT BOARD OF DIRECTORS REASONS

         In approving the Merger Agreement on February 6, 1996, the Board of
Directors of USAT took into consideration the following factors and those
hereinafter described in subsection (6):
    


                                       45
<PAGE>   51
   
         (A)  A MERGER WOULD ELIMINATE CERTAIN CONFLICTS OF INTEREST THAT COULD
AFFECT FUTURE OPERATIONS.

         In the opinion of the USAT directors, for the Company to have its best
opportunity to increase revenues and secure profitability, it should focus
solely on its alcohol and drug testing and human resource provider operations
as its core businesses, thereby necessitating the divestures of its toy and
rubber recycling subsidiaries, the latter of which divestitures was effected on
April 30, 1996.  The USAT Board believes that the three "core businesses" have
a synergy with each other, which its toy and rubber recycling operations do not
have, and thereby make a more attractive investment and a better combination on
which to build for the future.

         USAT's controlling interest in U.S. Drug and the fact that certain
directors of the USAT Board are also directors of the U.S. Drug Board has the
derivative effect of putting USAT in a position where it has a fiduciary duty
to the U.S. Drug Minority Stockholders as well as to the stockholders of USAT.
An example of this is as follows:  If USAT raises $2,000,000 in financing,
should such amount be invested in building up its own alcohol testing
operations and/or in the RSA/Proactive operations of which it owns 100%?  Or
should it invest all or part in U.S. Drug of which it owns only 67.0%?  Despite
the fiduciary duty of USAT to the U.S. Drug Minority Stockholders, USAT lacks
complete control of U.S. Drug.  The directors of USAT believe that the Merger
would benefit USAT in that, by exchanging the interests of the U.S. Drug
Minority Stockholders into interests in USAT, USAT will be in complete control
of the U.S. Drug and thus, have only one set of stockholders to which the
directors are responsible.

         (B)  USAT COULD CANCEL LOAN INDEBTEDNESS.

         At the time that the USAT Board approved the Merger, the USAT Board
considered the cancellation of its indebtedness to U.S. Drug as a factor.  On
June 18, 1996, however, the USAT Board elected to pay down its then outstanding
notes receivable to U.S. Drug in the amount of $282,295 and further agreed to
lend to U.S. Drug $500,000 to fund its current operations.  Therefore, the
cancellation of indebtedness is no longer relevant to USAT as a factor in favor
of consummating the Merger.  See "Material Contacts of USAT with U.S.
Drug-Loans from U.S. Drug to USAT".

(5) U.S. DRUG BOARD REASONS

         In approving the Merger Agreement on April 23, 1996, the Board of
Directors of U.S. Drug took into consideration the following factors and those
hereinafter described in (6):

         (A)  A ONE-PRODUCT COMPANY MAY BE AT A DISADVANTAGE IN A HIGHLY
COMPETITIVE MARKET PLACE, AS CONTRASTED WITH BEING PART OF
    


                                       46
<PAGE>   52
   
A COMPANY WITH THREE SYNERGISTIC OPERATIONS, TWO OF WHICH ARE ALREADY PRODUCING
REVENUES.

         After weighing the increased competitiveness in the drug testing
marketplace in 1996, the U.S. Drug Board concluded that a company concentrating
on one product (i.e., drug testing) has less of a chance to succeed in the
highly competitive and mature drug testing market than a company which has
three synergetic operations - alcohol testing, drug testing and human resource
provider - on which to build and which is not dependent on one product for its
potential growth.  The U.S. Drug Board believes that the ProActive operations
would increase the revenues of U.S. Drug's current drug testing operations, as
well as USAT's alcohol testing operations, by utilizing their respective
products with its customers.  In addition, the U.S. Drug Board shares the USAT
Board's belief that the alcohol testing operations will experience substantial
growth in subsequent years, especially when coupled with the other two
subsidiaries' businesses, because of the increasing awareness in the business
community that alcohol can adversely affect the efficiency of employees as do
drugs of abuse.  The U.S. Drug Board further believes that, by using Robert
Stutman as its spokesperson (see "Business of the
Company-Subsidiaries-ProActive Synergies, Inc./Robert Stutman and Associates,
Inc." for information as to his prior consulting arrangement) on alcohol and
drug testing, such awareness can be developed into business opportunities for
USAT's alcohol testing products.  See "Need For Revenues" under the subsection
"Factors Considered By Both Boards of Directors" below.  These factors become
even more important were the drug testing product development program to fail,
leaving U.S. Drug with no product to sell.

         (B)  NOT BEING A PUBLIC COMPANY WOULD RESULT IN CERTAIN COSTS SAVINGS.

         As a result of the Merger, U.S. Drug will save at least $50,000 to
$75,000 per year in expenses related to being a public company.

         (C)  THE U.S. DRUG COMMON STOCK MAY BE DELISTED.

         The U.S. Drug Board took into consideration that the declining assets
and stockholders' equity resulted, as of March 31, 1996, in the U.S. Drug
Common Stock not meeting the requirements for continued listing on the Pacific
Stock Exchange.  In order to maintain that listing in the event that the Merger
is not approved, U.S. Drug would require constant infusions of equity which
would have the effect of limiting other available methods of financing such as,
for example, debt financing.  In addition, the U.S. Drug Board recognized that,
because of the anticipated continuing losses, the possibility of U.S. Drug not
meeting such maintenance requirements would continue to be a
    


                                       47
<PAGE>   53
   
problem for at least 12 to 24 months.  The U.S. Drug Board also recognized
that, if U.S. Drug attempted to transfer the U.S. Drug Common Stock to either
the American Stock Exchange or the National Association of Securities Dealers
Automated Quotations ("NASDAQ") System, infusions of equity would be a
requirement to obtain any such alternative listing.  In this connection the
U.S. Drug Board considered the effect of trading of the U.S. Drug Common Stock
in the "pink sheets" if the U.S. Drug Common Stock were delisted from the
Pacific Stock Exchange and did not qualify for listing on the American Stock
Exchange or reporting on the NASDAQ System and concluded that its market price
may be substantially below the offer of shares of the USAT Common Stock having
a value of $5.25 per share of U.S. Drug Common Stock.  However, the USAT Board
gave greater weight to the other factors discussed in this section than
historical market value.  See also the discussion under factor (6)(f) in this
section "Reasons for the Merger and Approval."

         (D)  OBTAINING A MAJOR COMPANY TO FINANCE THE U.S. DRUG OPERATIONS
DOES NOT APPEAR TO BE A REALISTIC ALTERNATIVE.

         U.S. Drug could consider seeking a marketing partner for its products
(assuming the development program is successfully completed, as to which there
can be no assurance), however, management would prefer not to surrender future
revenues if possible.  In addition, U.S. Drug may consider requesting, as an
alternative to its seeking financing, that a major company advance funds for
the product development work and/or assist in performing certain of the
development assignments.  Such company may request that it be named as
marketing partner with the resultant impact on future revenues as the trade-off
for reducing current expenditures.  There can be no assurance that any such
marketing and/or product development partner can be obtained and that, if
obtained, when such partner will be obtained and to the extent it will agree to
make funds available in advance of the product development or the sales to
users.  The U.S. Drug Board concluded that it should not make its decision on
the speculation as to the availability of such a partner and should assume that
financing will be required.  Due to the highly speculative nature of the
Special Payment, the Boards of Directors of both USAT and U.S. Drug have urged
the U.S. Drug Minority Stockholders not to base their consent to the Merger on
the likelihood of there being a Special Payment. See also the discussion under
"Terms of the Transaction-Special Payment."

(6) FACTORS CONSIDERED BY BOTH BOARDS OF DIRECTORS

         Certain of the factors which the Board of Directors of USAT considered
in approving the Merger were also considered by the U.S. Drug Board of
Directors in granting their approval (collectively referred to herein as the
"Boards").  These factors were as follows:
    


                                       48
<PAGE>   54
   
         (A)  ONE-PRODUCT COMPANY HAS LESS OF A CHANCE IN A HIGHLY-COMPETITIVE
INDUSTRY.

         As noted in factor (5)(a) in this section "Reasons for the Merger and
Approval," the Boards concluded that a company concentrating on one product
(i.e., drug testing) has less of a chance to succeed in the highly competitive
and mature drug testing market than a company which has three synergetic
operations - alcohol testing, drug testing and human resource provider - on
which to build and which is not dependent on one product for its potential
growth.  The major competitors in the drug testing market, such as Roche and
Syva have other operations that sustain the development of their drug testing
operations.  Because the Boards do not expect U.S. Drug to realize revenues
from sales for a period of 20 to 30 months, as to which there can be no
assurance that U.S. Drug will meet such timetable, having other sources of
revenues and other potential sources for attaining profitability becomes an
even more important factor.  Although USAT has a history of losses - net losses
were $10,460,586, $7,236,396, and $10,066,035 in the fiscal years ending March
31, 1996, 1995, and 1996, respectively - and an accumulated deficit of
$41,469,501 as of March 31, 1996 and, although there can be no assurance that
the USAT Board will be correct in its expectations, the USAT Board believes
that as a result of the sale of USRR and the anticipated sale of Good Ideas,
and significant revenue generating potential of the ProActive human resource
provider operations, as supplemented by those of RSA, the Company has a better
opportunity of becoming profitable at an earlier date than U.S. Drug, and to
continue to produce significant revenues even after the drug testing operations
become revenue producing.

         (B)  THE COMPANY HAS A GREATER OPPORTUNITY AT OBTAINING FINANCING.

         As indicated above, USAT's management is optimistic about the Company
achieving a significant amount of revenues from the alcohol testing and the
human resource provider segments, particularly from the combined operations of
USAT's recently acquired RSA subsidiary and its ProActive subsidiary.  U.S.
Drug, however, will require additional time and money to bring its saliva based
product to market (currently estimated to be 20 to 30 months and approximately
$4,500,000 to $5,000,000 (not including manufacturing start-up costs),
respectively) and currently has no revenues. Because of USAT's above referenced
revenue prospects, the Boards believe that USAT has a better chance than U.S.
Drug of obtaining financing for the balance of the research and development of
U.S. Drug's products if such financing is based on all of the USAT's businesses
and assets, including U.S. Drug, rather than just on U.S. Drug's business and
assets.  The Board's belief is that an investor or lender may be more willing
to invest or extend credit if there is a known
    


                                       49
<PAGE>   55
   
revenue stream than just speculating as to possible revenues 20 to 30 months
off on a product in a mature market that is not currently available for
marketing and may never be.  Even if such financing is obtained by U.S. Drug,
management believes the terms for a U.S. Drug financing would not be as
favorable as those which could be obtained by USAT after the Merger.
Management again bases this opinion on the availability of revenues in the
Company as compared to sheer speculation in U.S. Drug.  USAT's Board does not
believe that USAT's history of losses will act as a deterrent to obtaining
future financing based on USAT's past experiences and the USAT Board's belief
that the new management and change in operational direction will help
facilitate such financing if required.  As discussed in the succeeding factor
(6)(c), the Boards believe that, if the Merger is not completed, U.S. Drug may
not be able to obtain such financing without causing substantial dilution to
both the U.S. Drug Minority Stockholders and USAT of their stock ownership and
voting rights.  USAT can avoid this result by the exercises of outstanding
options and warrants.  Because, as indicated in factor (6)(a), U.S. Drug is
essentially a one-product company, the Boards do not believe that investors
will invest in it because U.S. Drug is part of a company that has other
products and services.  In addition, the more that investors dilute USAT's
interest in U.S. Drug the less attractive it becomes to USAT to use its funds
in U.S. Drug as contrasted with the other operations of the Company which USAT
owns 100%.  There can be no assurance, however, that USAT management s revenue
or financing expectations will be achieved and in the time frame that
management contemplates.

         (C)  USAT HAS AN ALTERNATIVE METHOD OF FINANCING THAT WILL AVOID
DILUTION OF STOCKHOLDERS.

         The Boards recognized that an additional investment of at least
$4,500,000 and possibly as high as $7,500,000 will be necessary before U.S.
Drug will be able to offer its drug testing products to customers, assuming
that its research and development efforts are successfully implemented, as to
which there can be no assurance.  USAT's Board considered as an alternative
that U.S. Drug should seek to raise the necessary capital for U.S. Drug through
further sales of shares of the U.S. Drug Common Stock, but recognized that such
sales would not only dilute the stock ownership and voting rights of existing
stockholders of U.S. Drug, particularly USAT, assuming such sales were
successful, as to which there can be no assurance, but also there was no
assurance that any such sales would be on as favorable terms as if USAT sought
to raise funds through the sale of shares of the USAT Common Stock.  On the
other hand, USAT can secure the exercise of outstanding USAT Common Stock
purchase warrants and stock options without further diluting the stock
ownership or voting rights of the stockholders of USAT.  Although a rights
offering to the U.S. Drug stockholders would minimize additional dilution to
existing U.S. Drug stockholders, U.S. Drug's Board
    


                                       50
<PAGE>   56
   
recognized that the U.S. Drug Minority Stockholders might not respond favorably
to a rights offering because many of such stockholders purchased their shares
at $5.00 per share in the initial public offering or at higher prices in the
subsequent market, while the current market price, as of July __, 1996, is only
$_____ per share.  Further, the U.S. Drug Board considered that even if a
rights offering was priced below market, there was little assurance that such
an offering would generate sufficient capital to fund U.S. Drug's research and
development operations.  In addition, for the reason discussed in factor (4)(a)
of the section "Reasons for the Merger and Approval," to the extent USAT uses
funds in a rights offering to maintain its stock position in U.S. Drug, these
are funds which could have been used for another operation of the Company in
which it has 100% ownership.  To the extent USAT does not exercise its rights,
there are less funds available to U.S. Drug.  In addition, for the reasons
discussed herein and elsewhere in this section, there can be no assurance that,
if there was an oversubscription right, either USAT or the U.S. Drug Minority
Stockholders or a large number thereof would oversubscribe.  To the extent USAT
elected to oversubscribe, its stock interest in the U.S. Drug Common Stock
would rise.

         (D)  USAT AND U.S. DRUG MAY COMPETE FOR FINANCING.

         USAT's Board considered that, in the event of a rights offering, in
order to preserve USAT's ownership percentage in U.S. Drug by exercising its
rights, USAT may have to obtain its own financing, thereby competing against
U.S. Drug for financing because presumably U.S.  Drug would also be seeking
sources of financing other than from its own stockholders.  By exercising its
rights, USAT would be utilizing funds that might otherwise have been used, in
part, for the Company's other operations, such as its alcohol testing and human
resource provider operations.  Therefore, the USAT Board did not actively
consider the possibility of oversubscribing to a rights offering because USAT
would only gain 67.0% of the benefit from such an offering and such monies
could be invested into its alcohol testing and human resource provider
operations of which it would gain 100% of the benefit.  That the USAT Board
would be less willing to invest in the operations of U.S. Drug as a 67.0%
stockholder than it would be as a 100% stockholder was a factor which the U.S
Drug Board considered as well.

         (E)  U.S. DRUG MAY DEFAULT AND LICENSING RIGHTS WILL REVERT TO USAT.

         If U.S. Drug is unable to finance its research and development
efforts, an event of default will probably occur under its sublicense agreement
with USAT.  In such an event, the rights to the USN technology will revert to
USAT.  As the USN had rejected a novation of the licensing rights to U.S. Drug
and looks to USAT as the sole party to the license, this would
    





                                       51
<PAGE>   57
   
prevent U.S. Drug from continuing operations.  USAT would then have the right
to develop a drug testing product without making further investment in a 67.0%
owned entity.

         (F)  USAT COMMON STOCK MAY HAVE GREATER INVESTMENT VALUE.

         The Boards considered that the receipt by the U.S. Drug Minority
Stockholders of __ shares of the USAT Common Stock for each share of the
Minority U.S. Drug Common Stock is, in the Board's opinion, a better
alternative than retaining their shares in U.S. Drug if the Merger is not
consummated.  The U.S. Drug Common Stock is currently trading at a sales price
which is __% of the value of the USAT Common Stock being offered hereunder.
See the discussion in the succeeding factor (6)(g) and also the data under
"U.S. Drug Market Information-Market Data."  In addition to the USAT offer
carrying a premium over the current market price and over the initial public
offering price of $5.00 per share, the Boards did not believe that historical
market price of the Good Ideas Common Stock was significant because of the
limited trading volume as compared with that of the USAT Common Stock and the
fact that the initial higher prices were due to speculation that the drug
products would be available at an earlier date, while now it is clear that they
are at least two years away, assuming the feasibility study is successful and
the research and development program is satisfactorily completed, as to neither
of which there can be any assurance.  See also the discussion under factor
(6)(h) below.  While there can be no assurance that the value of the USAT
Common Stock will rise, the USAT Board believes that over a period of time this
security may bring greater value to the U.S. Drug Minority Stockholders than
holding the Minority U.S. Drug Common Stock for the reasons discussed in this
section and under "Terms of the Transaction-Special Payment," although there
can be no assurance that this value will be realized.

         (G)  U.S. DRUG'S LIQUIDATION VALUE NOT DEEMED SIGNIFICANT.

         The Boards, in making their respective evaluations, noted that, as of
March 31, 1996, U.S. Drug had a net book value of approximately $_ __ per share
as compared to the shares of USAT Common Stock having a value of $5.25 per share
of U.S. Drug Minority Common Stock which USAT is offering pursuant to this
Consent Solicitation Statement/Prospectus.  The USAT Board also considered the
"liquidation value" of U.S. Drug, but concluded that such factor was not
relevant in view of the fact that the main asset of U.S. Drug, i.e., the USN
technology, would revert to USAT on liquidation.
    





                                       52
<PAGE>   58
   
         (H)  U.S. DRUG'S "GOING CONCERN VALUE" CONSIDERED TO BE SPECULATIVE.

         The Boards reviewed the possible "going concern value" of U.S. Drug,
taking into account the fact that an infusion of at least $4,500,000 to
$5,000,000 would be necessary to fund the drug testing products' research and
development, that there can be no certainty that the products will be available
on a timely basis and that, when available, other companies may have developed
a competing saliva based product and concluded that an evaluation of "going
concern value" would be entirely speculative, even though the Boards have
confidence in the ability of U.S. Drug to develop a marketable product.  The
Boards recognized that, although the shares of the USAT Common Stock having a
value of $5.25 per share of Minority U.S. Drug Common Stock being offered is
above the 1993 initial public offering price of $5.00 per share and the closing
sales prices during the last six months, it is below the closing sales prices
of the U.S. Drug Common Stock for certain periods longer than six months ago.
See "U.S. Drug Market Information-Market Data."  The Boards also recognize
that, considering the current status of the drug testing products development
program, the market price of the U.S. Drug Common Stock, is not likely to rise
significantly during the next 12 months, if ever.

(7) REASONS FOR USING MERGER FORM

         Once the decision to take U.S. Drug private was made, the USAT Board
structured the transaction as a merger, rather than as a tender offer to the
U.S. Drug Minority Stockholders followed by a merger, because it believed that
a merger was a faster and less expensive method than was a tender offer to
achieve one of its primary objectives of having no minority stockholders in
U.S. Drug.  Moreover, the USAT Board selected a consent solicitation over a
proxy solicitation in order to save the time and expense of holding a meeting.
The USAT Board believed that the transaction should be effected at this time
before USAT initiated any further efforts to improve the business operations of
the Company, including those of U.S. Drug, and had all of its corporate
structural questions resolved.  If the Merger and the Good Ideas Merger
consummated, the USAT Board will operate USAT through divisions and not
subsidiaries for cost savings and other reasons.  If such transactions are
effected, the USAT Board will also consider changing USAT's name (an action
which would require USAT stockholder approval) to one more indicative of its
combined operations.

(8) EFFECT OF MERGER ON USAT

         The Merger will, in the opinion of the USAT Board for the foregoing
reasons, provide USAT with its best opportunity to increase the Company's
revenues and have the Company attain
    





                                       53
<PAGE>   59
   
profitability by enabling the Company to capitalize on the synergy of the three
core businesses and as a result, over time, increase the value of the USAT
Common Stock.  Moreover, there will be no federal tax consequences to USAT or
its stockholders as a result of the Merger.  However, the shares of USAT Common
Stock to be issued to the U.S. Drug Minority Stockholders will dilute the stock
ownership and voting rights of the current USAT stockholders.  Thus, the
current USAT stockholders who hold 100% of the outstanding shares of the USAT
Common Stock will hold ___% of the outstanding shares if the Merger is
consummated and __% if the Good Ideas Merger is also consummated.

(9) CONCLUSION

         The Boards have concluded that, for the foregoing reasons, the
consummation of the Merger is in the best interests of USAT and U.S.  Drug and
is fair to the U.S. Drug Minority Stockholders from a financial point of view.
In making its determination, the USAT Board considered factors (4)(a), (6)(a),
(6)(b) and (6)(c) in this section "Reasons for the Merger and Approval" more
important than the other factors it considered.  In making its determination,
the U.S. Drug Board considered factors (5)(a), (5)(d), (6)(a), (6)(b), (6)(c)
and (6)(f) more important than the other factors it considered.

         Both Boards recommend that the U.S. Drug Minority Stockholders consent
to the adoption of the Merger Agreement.  The directors of U.S.  Drug direct
attention to their affiliation with USAT and the attendant conflicts of
interests as described in the subsection "Authorization" of this section.

         In evaluating the Merger, the Boards of Directors of USAT and U.S.
Drug considered the oral presentations of Whale Securities that the Merger
exchange ratio is fair to the U.S. Drug Minority Stockholders from a financial
point of view.  In addition, before mailing this Consent Solicitation
Statement/Prospectus, they considered the written opinion of Whale Securities,
which confirmed the conclusion of such oral presentations and a copy of which
opinion is attached as Appendix B to this Consent Solicitation
Statement/Prospectus.  See the section "Fairness Opinion" below.

         In consideration of the foregoing reasons in this section "The Reasons
for the Merger and Approval," the Boards of Directors of USAT and U.S. Drug
both believe that this consent solicitation offer is substantively, as well as
procedurally, fair to the Good Ideas Minority Stockholders.

         There can be, of course, no assurance that any or all of the above
objectives will be achieved.

FAIRNESS OPINION

         Whale Securities is an investment banking firm primarily specializing
in the small cap market and is regularly engaged in the evaluation of small cap
companies and their securities in connection with equity and debt financings,
merger and acquisitions and valuations for corporate and other purposes.  Whale
Securities has not acted in the past on behalf of U.S. Drug, USAT or
Acquisition Corp. in any capacity.  In addition, there is no agreement or
understanding as to the future or current employment of Whale Securities except
in connection with the pending possible acquisition of the minority interest in
Good Ideas by USAT.  Various investment banking firms as to which counsel or
others in management had personal contacts were solicited as to their
availability to perform the analysis and, of the three firms which replied in
the affirmative, Whale Securities was selected based on its prior experience
and its reasonable fee for its services.

   
         U.S. Drug agreed to pay Whale Securities a fee of $35,000, of which
$17,500 was paid on Whale Securities' acceptance of the assignment, $8,750 will
be paid when Whale Securities concludes its findings and $8,750 will be paid
upon Whale Securities delivering its fairness opinion in definitive form.
Accordingly, the fee for the analysis and the report will be $26,250.
    

         Whale Securities has delivered a written opinion dated as of the date
hereof (the "Fairness Opinion") to the U.S. Drug Board stating its opinion
that, considered as a whole, the Merger exchange ratio is fair to the U.S. Drug
Minority Stockholders from a financial point of view as of the date of the
opinion.  The full text of the Fairness Opinion, which contains a description
of the assumptions and qualifications made, procedures followed and matters
considered by Whale Securities in rendering its opinion, is set forth as
Appendix B to this Consent Solicitation Statement/Prospectus, is incorporated
herein by reference and should be read in its entirety.

   
         In connection with its opinion dated as of the date of this Consent
Solicitation Statement/Prospectus, in arriving at its opinion, Whale Securities
reviewed and considered, among other things: (i) the Merger Agreement; (ii)
U.S. Drug's and USAT's Annual Reports on Forms 10- K for the three fiscal years
ended March 31, 1996, 1995 and 1994 and their Quarterly Reports on Form 10-Q
for the quarterly periods ended June 30, 1995, September 30, 1995, and December
31, 1995; (iii) certain information, including financial forecasts, relating to
the businesses, earnings and prospects of U.S. Drug and USAT, furnished to
Whale Securities by senior management; (iv) the historical market prices and
trading activity for U.S. Drug and USAT shares; and (v) publicly available
information concerning certain other companies and transactions which Whale
Securities considered relevant to its
    





                                       55
<PAGE>   61
   
analysis.  In addition, Whale Securities held discussions with the managements
of U.S. Drug and USAT for the purpose of reviewing the historical and current
operations of such companies and the business prospects for each.
    

     In conducting its analysis and in arriving at its opinion, Whale
Securities relied upon and assumed the accuracy and completeness of the
financial and other information that was publicly available or provided to
Whale Securities and Whale Securities did not undertake to independently verify
the same.  Whale Securities did not prepare or obtain any independent
evaluation or appraisal of U.S. Drug's or USAT's assets or liabilities.  Whale
Securities assumed and relied upon the senior management of U.S. Drug and USAT
as to the reasonableness and achievability of the financial and operating
forecasts furnished by management (and the assumptions and bases therefor).
Whale Securities' opinion was necessarily based on economic, market and other
conditions as in effect on, and the information made available to it as of, the
date of its opinion.   Whale Securities was retained by the Board of Directors
of U.S. Drug to act as financial advisor to U.S. Drug only with respect to its
fairness opinion.  In addition, in the ordinary course of its securities
business, Whale Securities may actively trade equity securities of U.S. Drug
and/or USAT and/or Good Ideas for its own account and the accounts of
customers, and Whale Securities, therefore, may from time to time hold a long
or short position in such securities.  The Fairness Opinion was directed to the
Board of Directors of U.S. Drug and does not constitute a recommendation to any
U.S. Drug Minority Stockholder as to how such a stockholder should consent on
any matter submitted for U.S. Drug stockholder consent in connection with the
Merger.

         In connection with the rendering of its opinion to the Board of
Directors of U.S. Drug, Whale Securities performed a variety of financial
analyses, including those summarized below.  Whale Securities believes that its
analyses must be considered as a whole and that selecting portions of such
analyses and the factors considered therein, without considering all factors
and analyses, could create an incomplete view of the analyses and the processes
underlying Whale Securities' opinion.  The preparation of a fairness opinion is
a complex process involving subjective judgments and is not necessarily
susceptible to partial analysis or summary description.  The projections
prepared by the management of each of U.S. Drug and USAT underlying Whale
Securities' analyses are not necessarily indicative of future results or
values, which may be significantly more or less favorable than such
projections.  Estimates of values of companies do not purport to be appraisals
or necessarily reflect the prices at which companies or their securities
actually may be sold.  Except as described below, none of the analyses
performed by Whale Securities was assigned a greater significance by Whale
Securities than any other.

         The projections furnished to Whale Securities were prepared by the
management of U.S. Drug and USAT.  U.S. Drug and USAT do not publicly disclose
internal management projections of the type provided to Whale Securities in
connection with the review of the proposed Merger.  Such projections were not
prepared with a view towards public disclosure.  The projections were based on
numerous variables and assumptions which are inherently uncertain, including,
without limitation, factors relating to general economic and competitive
conditions.  Accordingly, actual results could vary significantly from those
set forth in such projections.

   
         Whale Securities did not determine the amount of the consideration to
be paid by USAT to the U.S. Drug Minority Stockholders nor did it make a
recommendation as to the exchange ratio which was determined by the USAT Board
and then communicated to Whale Securities for review in preparation of the
Fairness Opinion.  Due to the speculative nature of the Special Payment, Whale
Securities did not place significant value on the Right of a U.S. Drug Minority
Stockholder to receive such a payment.  See the section "Special Payment" under
the caption "Terms of the Transaction."
    

         The following is a brief summary of certain factors which Whale
Securities discussed with the Board of Directors of U.S. Drug which figured
prominently in Whale Securities's valuation of U.S. Drug and certain analyses
performed by Whale Securities in connection with the Fairness Opinion.

   
         1. Certain factors considered in the evaluation of U.S. Drug:

         Whale Securities noted that U.S. Drug is a development stage company
and because it is pioneering a unique drug detection methodology, there are
many uncertainties which affect its valuation.  Among these uncertainties are
the likelihood the tests can in fact be successfully developed, the cost of
such development, the time period for development of the tests and FDA
approval, identification of a manufacturer for the products and the cost of
manufacture, identification of a development partner to market the products and
the terms of such an arrangement, customer acceptance of the products, and the
competitive environment at such time as the products are ready for marketing.
In reviewing the elements of value in U.S. Drug, Whale Securities pointed out
that U.S. Drug has five full-time employees and that, though additional
employees may be hired, U.S. Drug is, and expects to be on a continuing basis,
dependent on third parties for significant portions of product development and
future manufacture and marketing of its products.  U.S. Drug expects it will be
20 to 30 months before its saliva based testing products will be ready for
marketing and some additional time before any significant revenues from such
products are realized.  Management
    





                                       57
<PAGE>   63
   
estimates U.S. Drug will require between $4,500,000 and $5,000,000 of
incremental capital to complete development of its products.  This does not
include the $2,000,000 to $2,500,000 in incremental capital required for
manufacturing line start-up expenses relating to the chemistry aspects of the
product assuming that the development program is completed, as to which there
can be no assurance.  Because U.S. Drug currently lacks the capital resources
to fund such development, it will need to seek funding from capital market
sources or industry partners, either of which would likely be dilative to the
current stockholders of U.S. Drug.

         In reviewing the alternatives faced by the U.S. Drug Minority
Stockholders, Whale Securities discussed the facts that U.S. Alcohol holds a
control position by its 67.0% ownership of the U.S. Drug Common Stock and, as
such, USAT could delay or possibly prevent a sale of U.S.  Drug to a third
party.  USAT currently provides both management services and facilities under
contract to U.S. Drug.  Further, the core technology used by U.S. Drug in its
products is held under sublicense from USAT.  Also the alcohol testing business
of USAT presents marketing synergies with the drug testing business under
development by U.S. Drug.  These factors favorably position USAT as a buyer and
represent a formidable barrier to an acquisition of U.S. Drug by third parties.
While USAT's control position does not directly impact Whale Securities'
Opinion as to fair value, it did, in the opinion of Whale Securities, diminish
the likelihood of alternative offers arising competitive to that of USAT to the
U.S. Drug Minority Stockholders.  Whale Securities also noted that U.S. Drug's
Board and management confirmed they had not been presented in the past year
with third party offers or overtures for purchase of U.S. Drug.  It is common,
in the experience of Whale Securities, for third parties to initiate such
discussions during periods of management and board restructuring and upon the
announcement of an acquisition offer thought to be undervalued.  The fact that
no offer has been made and no offer is likely to be made for the foregoing
reasons are, in the opinion of Whale Securities, confirmatory of the fairness
of USAT's offer.

         In reviewing the USAT offer, Whale Securities noted that based on
5,221,900 shares of the U.S. Drug Common Stock outstanding, the consideration
of $5.25 per share valued U.S. Drug at $27,400,000.  This compared with a
market capitalization for U.S. Drug shares of $17,000,000 on January 30, 1996,
one week prior to the announcement of the USAT merger offer, and a
stockholders' equity, based on the December 31, 1995 balance sheet, for U.S.
Drug of $1,503,000 on the same date (i.e., January 30, 1996).  Under the terms
of the proposed Merger, the U.S. Drug Minority Shareholders would be receiving
registered USAT shares, freely tradable by the holders.  Whale Securities noted
that in the three months prior to the announcement of the USAT merger offer,
the U.S. Drug Common Stock had an average
    





                                       58
<PAGE>   64
   
trading volume of approximately 64,000 shares per month.  During the same time
period, the USAT Common Stock had an average trading volume of approximately
2,000,000 shares per month.  Hence, the U.S. Drug Minority Stockholders upon
the Merger would hold a far more liquid security in USAT shares than in U.S.
Drug shares.  Whale Securities estimated that if USAT's share price held
constant at $3.125 throughout the 30-day period prior to the Record Date, the
U.S. Drug Minority Shareholders would receive approximately 2,900,000 shares of
the USAT Common Stock under the proposed Merger.  During each of two weeks in
March 1996, the USAT Common Stock traded in excess of 2,000,000 shares.  Whale
Securities noted it had been advised by counsel to U.S. Drug and counsel to
USAT that, in their opinions, the receipt of USAT shares by the U.S. Drug
Minority Shareholders would be treated as a tax free exchange.  Whale
Securities also reviewed the possibility of the U.S. Drug Minority Shareholders
receiving additional compensation from USAT in the event, during the first year
following the proposed Merger, U.S. Drug or Acquisition Corp. receives cash
payments under a Development and Marketing Agreement for U.S. Drug's proposed
products.
    

         
         2.      Whale Securities' analysis encompassed a number of valuation
approaches including:

   
         (a)     Market value of the U.S. Drug shares and premiums to market
for acquisitions -- The USAT offer to merge U.S. Drug with and its subsidiary
was announced on February 6, 1996.  The market prices for the U.S. Drug Common
Stock on February 5, 1996 and on January 30, 1996, one day and one week,
respectively, prior to the announcement, were $3.75 and $3.25 per share.  The
exchange offer computed based on $5.25 payable in USAT shares for each U.S.
Drug share represents a premium of 62% over the $3.25 U.S. Drug share price one
week prior to the announcement and exceeds by 31% the highest price ($4.00) at
which U.S. Drug shares have traded at any time in the six months prior to the
announcement of the offer.  Whale Securities noted that, for the market as a
whole, acquirors of U.S. publicly traded companies paid a premium of 45% in
1995, and 42% in 1994, over the quoted price of the acquiree's shares one week
prior to the announcement of the acquisition offer.
    

         (b)     Asset based methods - U.S. Drug's book value per share at
December 31, 1995 was $0.29 per share based on a net worth at December 31, 1995
of $1,503,303.  Due to the fact that since that time U.S. Drug has continued to
incur expenses without revenues, U.S. Drug's net worth and book value per share
through March 31, 1996 have declined from the December 31, 1995 level.  The
USAT offer valued at $5.25 per U.S. Drug share represents a multiple of 18.2
times U.S. Drug's book value at December 31, 1995 and 18.6 times U.S. Drug's
tangible book value at December 31, 1995.  Whale Securities noted that on April
12, 1996 the Market Guide Inc.(TM) composite of public companies in the medical
supply and





                                       59
<PAGE>   65
biotechnology industry categories and the S&P 500 traded at an average price to
book value multiple of 6.5, 7.8, and 4.4, respectively.  Whale Securities
considered liquidation value as a measure of value for U.S. Drug, but
determined that because the main asset of U.S. Drug, its USN technology, would
revert to USAT on liquidation, this value was not relevant and in any case
would likely result in an amount well below that of the USAT offer.

   
         (c)     Income, cash flow, and discounted cash flow based methods --
Whale Securities considered the use of income, cash flow and discounted cash
flow based methods in valuing the shares of U.S. Drug.  As discussed, U.S. Drug
does not expect to generate any meaningful revenues for at least the next two
years.  The management of U.S. Drug has not prepared projections for the
business of U.S. Drug beyond September 30, 1996.  Given the facts that U.S.
Drug is in the development stage and there are considerable uncertainties in
terms of the timing and costs of developing the saliva based products, as well
as future revenue and cost projections, Whale Securities' methodology was to
compare the USAT offered value of $27,400,000 (based on 5,200,000 U.S. Drug
shares valued at $5.25 per share) against the present value of future cash flow
streams under varying assumptions using discount rates of 20%, 30% and 40% per
annum.  Whale Securities also calculated the average annual cash flow that
would be required over a 20-year period (with no residual value) using the same
discount rates to justify the purchase price being paid by USAT, including
estimated development expenditures required to bring the product to market.
The USAT offer compared favorably to the present value of future cash flows of
the scenarios considered most appropriate by Whale Securities.

         (d)     Comparison to similar public companies and similar sale
transactions -- Whale Securities identified over 60 publicly traded companies
operating in U.S. Drug' business segment as broadly defined.  A group of ten
companies were identified with features somewhat comparable to U.S. Drug in
terms of diagnostic orientation and relatively low revenues compared to market
valuation.  The ten companies used in the analysis were: Abaxis, Inc.,
Biomerica, Inc., Cytogen Corporation, Diametrics Medical, Inc., Drug Screening
Systems, Inc., Editek, Inc., Editope, Inc., Immunomedics Inc., Mortel
Biosciences Corp. and Matritech Inc.  As only one company had earnings, the
group generally traded on future profit potential based on products being
marketed or under development.  The ratio of price to book value for the
comparison group ranged from 2.4 times to 18.8, with the median and average
price/book ratios of 7 times and 8 times, respectively.  This compared to a
price/book ratio of 18.2 times for U.S. Drug based on a $5.25 per share price
under the Merger.  Whale Securities similarly reviewed mergers and acquisitions
in the diagnostics, medical supply, biotech and medical laboratory industry
segments.  Because of the uniqueness of the U.S.  Drug situation in terms of
its technology under development, lack of operations, revenues
    





                                       60
<PAGE>   66
and earnings, Whale Securities felt no specific transaction or group of
transactions were sufficiently comparable to the U.S. Drug merger so as to be
defining in terms of the valuation of U.S. Drug.  However, the premiums to
market price and the multiple of book value per share under the USAT offer
compared favorably with composite statistics for the industry segments
mentioned above.

   
         (e)     Analysis of the USAT Common Stock to be given as consideration
- -- In its review of the consideration to be received by the U.S. Drug Minority
Shareholders, Whale Securities noted that the USAT Common Stock issued in
connection with the Merger will be registered shares, freely tradable.  Based
on USAT's average weekly trading volume during February and March 1996 of
approximately 1,500,000 shares, unless conditions changed, the  U.S. Drug
Minority Stockholders would hold relatively liquid securities in the USAT
shares.  In reaching this conclusion, Whale Securities noted that USAT owned
67.0% of the outstanding shares of the U.S. Drug Common Stock and that USAT has
approximately 34,000,000 shares and U.S. Drug has approximately 1,700,000
shares held by non-affiliates, but considered neither fact relevant to the
question of liquidity which, in Whale Securities' opinion, is determined by the
ability of the stockholder to sell in the marketplace and not by the percentage
of his, her or its ownership.  Accordingly, in the opinion of Whale Securities
based on current market conditions, a holder of shares of the U.S. Drug Common
Stock having a value of $100,000 would find it easier to realize such value if
he, she or it were holding a comparable value of the USAT Common Stock.

         Whale Securities noted that the share price of USAT trended up sharply
from February to April 1996 from the $2.375 per share USAT price on February 5,
1996, the day prior to the announcement of the Merger offer.  Whale Securities
cautioned management and the U.S. Drug Board that a decline in USAT share
prices between the Record Date and the closing of the Merger would result in
the holders of the Minority U.S. Drug Common Stock receiving less consideration
than the amount contemplated under the Fairness Opinion.
    

         In connection with the Fairness Opinion, Whale Securities performed
procedures to update, as necessary, certain of the analyses described above and
reviewed the assumptions on which such analyses were based and the factors
considered in connection therewith.

TERMS OF THE MERGER AGREEMENT

   
         The following description of the Merger Agreement describes the
material terms thereof.  U.S. Drug Minority Stockholders are also directed to
Appendix A to this Consent Solicitation Statement/Prospectus where the full
text of the Merger is set forth.
    

(1)  CONVERSION OF SHARES

   
         After adoption of the Merger Agreement by the requisite consents of
the U.S. Drug stockholders, U.S. Drug will be merged with and into Acquisition
Corp. and each share of the Minority U.S. Drug Common Stock issued and
outstanding on the Effective Date will be converted into ________ shares of the
USAT Common Stock; each share of the U.S. Drug Common Stock owned by USAT will
be canceled; U.S. Drug Options to purchase 110,000 shares of the U.S. Drug
Common Stock will be cancelled and U.S. Drug Options to purchase 42,000 shares
of the U.S. Drug Common Stock at $7.00 per share will either be exercised into
shares of the U.S. Drug Common Stock on or prior to the Effective Date, in
which event the shares will be converted into shares of the USAT Common Stock
on the same basis as the Minority U.S. Drug Common Stock, or, if not exercised,
will expire on the Effective Date; and all outstanding U.S. Drug Warrants to
acquire an aggregate of 150,000 shares of the U.S. Drug Common Stock at $7.50
per share will be converted into the Merger Warrants of USAT to acquire
____________ shares of the USAT Common Stock at an exercise price of $_____ per
share.  See the section "U.S. Drug Options and Warrants" under this caption
"The Merger and Related Matters." An aggregate of __________ shares of the USAT
Common Stock will be issued to the U.S. Drug Minority Stockholders, subject to
adjustment for fractional shares.  Assuming that there are no exercises of
outstanding Common Stock purchase warrants or stock options or any conversions
of USAT preferred stock between the date of this Consent Solicitation
Statement/Prospectus and the effective date of the Merger, the USAT
stockholders will own ___% of the outstanding shares of the USAT Common Stock
and the U.S. Drug Minority Stockholders will own ___%.  The number of shares of
the USAT Common Stock to be exchanged for each share of the Minority U.S. Drug
Common Stock was determined by dividing $5.25 by the average of the closing
sales prices per share of the USAT Common Stock as reported on the American
Stock Exchange during the 30 days prior to the Record Date, which average sales
price per share was $_________.  No fractional shares of the USAT Common Stock
will be issued.  Holders of the U.S. Drug Common Stock entitled to receive on
the Effective Date fractional shares of the USAT Common Stock upon the
consummation of the Merger will receive in lieu thereof a cash payment
calculated on the basis of the closing sales price for a share of the USAT
Common Stock on the Effective Date (or on the first day thereafter as such
price is available).
    





                                       62
<PAGE>   68
(2)  EFFECTIVE DATE

         The Merger will become effective on the date and at the time of the
filing of a copy of the Certificate of Merger with the Secretary of State of
Delaware (i.e., the Effective Date).  This filing will occur as soon as
practicable following the receipt of consents from the holders of more than 50%
of the outstanding shares of the Minority U.S. Drug Common Stock and a consent
from USAT and the satisfaction of other conditions and it is currently expected
to take place on or about __________, 1996.  The Merger Agreement requires the
parties to close within five business days after the last condition to the
Merger has been satisfied or waived.  Either USAT or U.S. Drug is entitled,
however, to abandon the Merger prior to the consummation for the reasons
referred to below in the subsections "Conditions to the Merger" and "Amendment
and Termination Rights" in this section "Terms of the Merger Agreement" under
this caption "The Merger and Related Matters."

(3)  CONDITIONS TO THE MERGER

         The obligations of USAT (and Acquisition Corp.) and U.S. Drug under
the Merger Agreement are subject to the satisfaction of certain conditions
(unless such conditions are waived by the party intended to receive the benefit
of those conditions), including (1) the condition that the representations and
warranties of the parties set forth in the Merger Agreement shall be true in
all material respects on the date of the Merger, (2) the performance by each
corporation in all material respects of all obligations to be performed by it
under the Merger Agreement, (3) the receipt of closing certificates and (4) the
receipt of all requisite consents from all governmental agencies and third
parties which are required to effect the Merger, including, without limitation,
(a) that this Registration Statement has been declared effective by the
Commission, (b) that no stop order shall have been issued or proceedings for
such purpose shall have been instituted and (c) that the issuance of the USAT
Common Stock shall have all requisite authorizations under state securities or
"blue sky" laws for issuance.

         The obligations of USAT under the Merger Agreement are subject to the
satisfaction of certain conditions (unless such conditions are waived by USAT
except as indicated in the second succeeding paragraph), including (1) the
consent to the adoption of the Merger Agreement by the holders of more than 50%
of the shares of the U.S. Drug Minority Common Stock, (2) the obtaining of a
fairness opinion to the U.S. Drug Minority Stockholders reasonably satisfactory
to USAT and (3) the lack of any material adverse change in the business or
financial condition of U.S. Drug.





                                       63
<PAGE>   69
         The obligations of U.S. Drug under the Merger Agreement are subject to
the satisfaction of certain conditions (unless such conditions are waived by
U.S. Drug except as indicated in the succeeding paragraph), including (1) the
consent to the adoption of the Merger Agreement by the holders of more than 50%
of the outstanding shares of the Minority U.S. Drug Common Stock, (2) the
obtaining of a fairness opinion to the U.S. Drug Minority Stockholders
reasonably satisfactory to U.S. Drug and (3) the lack of any material adverse
change in the business or financial condition of the Company (excluding U.S.
Drug).

         The conditions that (1) the holders of more than 50% of the
outstanding shares of the Minority U.S. Drug Common Stock consent to the
adoption of the Merger Agreement; (2) a fairness opinion be obtained; and (3)
the Registration Statement has been declared effective and there is no "stop
order" in effect are not waivable by either USAT or U.S. Drug.

         If either party terminates its obligations under the Merger Agreement
to consummate the Merger because a condition precedent thereto has not been
satisfied, its sole obligation to the other party shall be to pay its own costs
which it agreed to pay on consummation of the Merger and which were incurred in
connection with the proposed transactions.  See the section "Fees and Expenses"
under this caption "The Merger and Related Matters."

(4)  AMENDMENT AND TERMINATION RIGHTS

         The Merger Agreement provides that the respective Boards of Directors
of USAT and U.S. Drug may, by written agreement, amend the Merger Agreement at
any time before or after its adoption by the U.S. Drug Minority Stockholders,
provided that after such approval no amendment may be made which changes either
the amount or the form of the consideration to be received by the holders of
the Minority U.S. Drug Common Stock pursuant to the Merger Agreement without
further approval by the U.S. Drug Minority Stockholders.

         The Merger Agreement, as amended, may be terminated and the Merger
abandoned, whether before or after approval by the U.S. Drug Minority
Stockholders, at any time prior to the Effective Date (1) by mutual written
consent of the Boards of Directors of USAT and U.S. Drug, (2) by either USAT or
U.S. Drug if the respective Board of Directors, based on the opinion of its
outside counsel, determines that making a recommendation to the U.S. Drug
Minority Stockholders to adopt the Merger Agreement could reasonably be deemed
to cause the members of such Board of Directors to breach their fiduciary
duties under applicable law to their respective stockholders or (3) by either
USAT or U.S. Drug if there is any statute, rule or regulation which makes
consummation of the Merger illegal or otherwise prohibited or any order,
decree, injunction or judgment enjoining Acquisition





                                       64
<PAGE>   70
Corp., USAT or U.S. Drug from consummating the Merger, and such order, decree,
injunction or judgment has become final and non-appealable.  The obligations
automatically terminate if the Merger has not been consummated by December 31,
1996.

SUMMARY OF THE TERMS OF THE USAT COMMON STOCK

(1)  GENERAL

   
         USAT is authorized to issue 50,000,000 shares of the USAT Common
Stock, $.01 par value.  Holders of the USAT Common Stock (i) have one vote per
share; (ii) have equal rights to any dividends declared by the Board of
Directors of USAT after payment of all accrued and unpaid dividends on USAT's
Class A Preferred Stock and any other preferred stock hereafter issued which
has a preference as to dividend payments; (iii) are entitled to share in all
assets available for distribution to stockholders upon liquidation, dissolution
or winding up of USAT's affairs after payment of all preferences on the Class A
Preferred Stock and any other preferred stock hereafter issued which has a
preference upon liquidation, dissolution or winding up of USAT; (iv) have no
preemptive, subscription or conversion rights; and (v) have no sinking fund
provisions.  There are no provisions in the Bylaws or the Certificate of
Incorporation of USAT which discriminate against any existing or prospective
holder of the USAT Common Stock as a result of such holder's ownership of a
substantial amount of the USAT Common Stock.  All outstanding shares of the
USAT Common Stock are, and all shares to be issued upon the consummation of the
Merger and the Good Ideas Merger will be, fully paid and nonassessable.

         Reference is made to "USAT Management-Directors and Officers" for a
description of how the USAT directors are elected by the holders of the USAT
Common Stock on a classified basis.  With a classified Board of Directors, at
least two annual meetings of stockholders, instead of one, will generally be
required to effect a change in the majority of USAT's Board.  As a result, a
classified Board may discourage proxy contests for the election of directors or
a purchase of a substantial block of the USAT Common Stock because its
provisions could operate to prevent obtaining control of the USAT Board of
Directors in a relatively short period of time.  The classification provisions
could also have the effects of discouraging a third party from making a tender
offer or otherwise attempting to obtain control of USAT.  There are no other
provisions in USAT's Certificate of Incorporation or By-Laws that may have the
effect of delaying, deferring or preventing a change in control of USAT and
that would operate with respect to an extraordinary corporate transaction
involving USAT or any of its subsidiaries, such as a merger, reorganization,
tender offer, sale or transfer of substantially all of its assets, or
liquidation.  The Board would have the power, without seeking further
stockholder approval, to
    





                                       65
<PAGE>   71
   
include such provisions in the Class B Preferred Stock described in the
succeeding paragraph, but has no current intention of reissuing such security
or including any such provision.

         There are 500,000 shares of the Class A Preferred Stock, $.01 par
value, authorized, of which 41,157 shares were outstanding as of March 31,
1996.  These shares have a liquidation preference of $205,785 and are
convertible into 185,207 shares of the USAT Common Stock.  As of June 30, 1996,
there was no other series of the USAT preferred stock outstanding, although
there are 1,500,000 shares of the Class B Preferred Stock, $.01 par value,
authorized.
    

(2)  ELECTION OF DIRECTORS

         Holders of the USAT Common Stock have no cumulative voting rights,
which means that stockholders owning more than 50% of the outstanding shares of
the USAT Common Stock can vote to elect all directors.  Accordingly, the
remaining stockholders would not be able to elect any.  In addition, USAT's
directors are elected on a classified basis.

(3)  DIVIDENDS

         Dividend payments on the USAT Common Stock are discretionary with the
USAT Board of Directors and depend on various factors, including earnings,
capital requirements and financial condition.  USAT has no current plan to pay
cash dividends on the USAT Common Stock in the foreseeable future because of
the cash requirements of the Company and its history of losses.  See "USAT
Market Information-Dividend Policy" elsewhere in this Prospectus.

(4)  TRANSFER AGENT

     The Transfer Agent for the USAT Common Stock is U.S. Stock Transfer
Corporation, 1745 Gardena Avenue, Suite 200, Glendale, CA 91204.

(5)  ACQUISITION SHARES

   
         The January 1992 Registration Statement, under the Securities Act,
registered 3,000,000 shares of the USAT Common Stock (the "Acquisition Shares")
solely for offer and issuance to the owners of businesses or properties which
USAT may acquire.  USAT intends to sign agreements restricting the recipients
of the Acquisition Shares from their resale or transfer for specific periods
unless USAT gives its prior written consent.  USAT has no agreements,
arrangements, proposals or understandings regarding any acquisitions at this
time.  As of June 30, 1996, USAT had 1,532,679 registered Acquisition Shares at
its disposal for future acquisitions.  See "Business of the
Company-Subsidiaries" for information as to the prior issuance of an aggregate
of
    





                                       66
<PAGE>   72
   
1,467,321 shares of the Acquisition Shares relating to the acquisitions of
USRR's assets, Alconet and RSA.
    

         Notwithstanding the registered status of the Acquisition Shares,
recipients of these shares offering them for public resale may potentially be
deemed statutory underwriters because they would be engaged in a public
distribution of securities.  An additional registration under the Securities
Act might, therefore, be required disclosing the nature of the acquisition, the
shares received as consideration and the manner of their distribution and sale
before the recipient could resell the Acquisition Shares.

DIFFERENCES IN STOCKHOLDERS' RIGHTS

         The U.S. Drug Minority Stockholders will become holders of the USAT
Common Stock if the Merger is consummated.  Because both U.S. Drug and USAT are
incorporated under the laws of Delaware, there will be no change in the
statutory rights as stockholders of the U.S. Drug Minority Stockholders when
they become stockholders of USAT.  See the section "Summary of the Terms of the
USAT Common Stock" under this caption "The Merger and Related Matters."

DIFFERENCES IN BY-LAWS

         There are no material differences between the By-Laws of U.S. Drug and
those of USAT.

EXCHANGE OF CERTIFICATES

         At the Effective Date, each share of the Minority U.S. Drug Common
Stock outstanding immediately prior to the Effective Date will be converted
into the right to receive ________ shares of the USAT Common Stock.  The shares
of the U.S. Drug Common Stock owned by USAT on the Effective Date will be
canceled.  Promptly after the Effective Date, a transmittal form will be
furnished by U.S. Stock Transfer Corporation, as Exchange Agent, to the U.S.
Drug Minority Stockholders.  The transmittal form will contain instructions
with respect to the surrender of the certificates for the Minority U.S. Drug
Common Stock in exchange for the certificates for the USAT Common Stock.
MINORITY U.S. DRUG COMMON STOCK CERTIFICATES SHOULD NOT BE FORWARDED TO THE
EXCHANGE AGENT UNTIL AFTER RECEIPT OF THE TRANSMITTAL FORM AND SHOULD NOT BE
RETURNED TO U.S.  DRUG WITH THE ENCLOSED CONSENT FORM.  Upon surrender of stock
certificates for exchange to the Exchange Agent, together with the letter of
transmittal duly executed, the holder of such certificates will be entitled to
receive in exchange therefor certificates representing the number of shares of
the USAT Common Stock equal to the shares of the Minority U.S. Drug Common
Stock held by him, her or it in accordance with the Merger Agreement.





                                       67
<PAGE>   73
         After the Effective Date, a record holder of the Minority U.S. Drug
Common Stock will have no rights with respect to such stock except to surrender
the certificates in exchange for certificates representing the USAT Common
Stock.  No dividends or other distributions declared after the Effective Date
with respect to shares of the USAT Common Stock issuable upon conversion of
shares of the Minority U.S. Drug Common Stock and payable to the holders of
record of the USAT Common Stock after the Effective Date will be paid to the
holder of any unsurrendered certificate representing the Minority U.S. Drug
Common Stock until the holder thereof surrenders such certificate in exchange
for certificates representing the appropriate number of shares of the USAT
Common Stock.  Subject to the effect, if any, of applicable law, after
subsequent surrender and exchange of a certificate, the record holder will be
entitled to receive any dividends or other distributions, without any interest
thereon, which theretofore had become payable with respect to the shares of the
USAT Common Stock for which such certificate was exchangeable.  Because of the
current intention of the USAT Board of Directors not to pay dividends on the
USAT Common Stock (see the section "Summary of the Terms of the USAT Common
Stock-Dividends" under this caption "The Merger and Related Matters" and "USAT
Market Information-Dividends"), the foregoing discussion may be moot.

         For all other purposes, however, including all right, if any, to vote
with respect to all matters, each certificate which represented outstanding
shares of the Minority U.S. Drug Common Stock before the Merger will be deemed
to represent ownership of shares of the USAT Common Stock into which those
shares are converted by the Merger.

U.S. DRUG OPTIONS AND WARRANTS

   
         U.S. Drug Options to purchase an aggregate of 110,000 shares of the
U.S. Drug Common Stock at $7.00 per share are currently held by the directors
of U.S. Drug and will be cancelled with the consent of such persons effective
upon the consummation of the Merger.  Pursuant to the terms thereof, as a
result of their resignations, the Options held by each of Karen B. Laustsen,
James C. Witham and Gary S. Wolff will expire on August 26, 1996, August 29,
1996 and October 1, 1996, respectively.  U.S. Drug Options to purchase an
aggregate of 10,000 shares held by Glenn A. Bergenfield and William DiTuro,
former directors of U.S. Drug, expired on February 14, 1996.  Douglas G. Allen,
the President of U.S.  Drug until July 31, 1996, and Steven Kline, a Vice
President of U.S. Drug, hold U.S. Drug Options to purchase 30,000 and 12,000
shares of the U.S. Drug Common Stock, respectively.  Pursuant to the terms
thereof, each such Option will, immediately prior to the consummation of the
Merger, become fully exercisable.  Because USAT has declined to assume these
U.S. Drug Options, they will expire if not exercised on or before the
    





                                       68
<PAGE>   74
   
Effective Date.  In addition, even if the Merger has not been consummated, Mr.
Allen's Option, pursuant to its terms and the termination of his employment,
will expire on October 29, 1996.  Because of the higher exercise price (i.e.,
$7.00 per share) as compared with USAT's offer to the U.S. Drug Minority
Stockholders, (i.e., $5.25 per share) USAT does not anticipate any exercises of
the U.S. Drug Options.  If the Merger is consummated, USAT may negotiate
alternative stock arrangements with respect to the USAT Common Stock for Mr.
Kline in connection with his continued employment.

         The only Common Stock purchase warrants to purchase shares of the U.S.
Drug Common Stock currently outstanding are the U.S. Drug Warrants owned by
Baraban or its designees.  Baraban was the underwriter of U.S. Drug's initial
public offering.  The U.S. Drug Warrants evidence the right to purchase 150,000
shares of the U.S. Drug Common Stock at $7.50 per share.  If the Merger is
consummated, as a result of the anti-dilution provisions of the U.S. Drug
Warrants, the U.S. Drug Warrants will be converted into USAT Common Stock
purchase warrants expiring October 13, 1998 (i.e., the Merger Warrants) to
purchase an aggregate of __________ shares of the USAT Common Stock, which is
the same number of shares which the holders of the U.S. Drug Warrants would
have been entitled to after consummation of the Merger had the U.S. Drug
Warrants been exercised immediately prior to the consummation of the Merger.
The exercise price of the Merger Warrants will be proportionately adjusted to
$_________ per share pursuant to the anti-dilution provisions of the U.S. Drug
Warrants.

         Except for the number of shares of the USAT Common Stock issuable upon
the exercise of the Merger Warrants and the exercise price, both as indicated
in the preceding paragraph, the Merger Warrants will be identical to the U.S.
Drug Warrants in terms and conditions.  The number of shares issuable upon
exercise and the exercise price are subject to adjustment in the event of
(1)(a) a stock dividend, (b) a subdivision of the USAT Common Stock, (c) a
combination of the outstanding shares of the USAT Common Stock into a smaller
number of shares and (d) a reclassification of the shares of the USAT Common
Stock into other securities of USAT (including a reclassification effected by a
merger or consolidation in which USAT is the continuing corporation); (2) the
issuance by USAT of rights, options or warrants to all holders of the USAT
Common Stock to purchase shares of the USAT Common Stock at a price which is
below the then market price per share of the USAT Common Stock; or (3) a
consolidation or merger of USAT or a sale by USAT of all or substantially all
of its property.  The adjustments are intended to place the holder of the
Merger Warrant in the same position the holder would have been had the Merger
Warrant been exercised prior to the event.  No fractional share will be issued
upon
    





                                       69
<PAGE>   75
   
exercise and a cash payment based on the then market price of the USAT Common
Stock shall be paid in lieu thereof.

         Because the shares of the USAT Common Stock issuable upon the exercise
of the Merger Warrants have been registered under the Securities Act in this
Registration Statement, they are freely tradeable unless issued to an
"underwriter" as such term is defined in Rule 145(c) under the Securities Act.
See the section "Resale of USAT Securities" under this caption "The Merger and
Related Matters."
    


REGULATORY APPROVALS

         As of the date hereof, the Merger requires no approval by any federal
or state governmental agency, except for compliance with the Securities Act,
the Exchange Act and state "blue sky" or securities laws.  Without limiting the
foregoing, no compliance is necessary under the Hard-Scott-Rodino Antitrust
Improvement Act of 1976, as amended, and the rules and regulations thereunder.

ACCOUNTING TREATMENT

         The Merger will be accounted for as a "purchase" as such term is used
under generally accepted accounting principles.

FEES AND EXPENSES

         Whether or not the Merger is consummated, all fees and expenses
incurred in connection with the Merger and the transactions contemplated
thereby will be paid by USAT, except that U.S. Drug will pay Whale Securities
for the fairness opinion (up to $35,000 as a fee plus out-of-pocket expenses)
and the fees and disbursements of Rosenman & Colin, LLP, its special counsel.
Such fees and expenses to be paid by USAT include any expenses incurred in
connection with the preparation, printing and distribution of this Consent
Solicitation Statement/Prospectus, including, without limitation, attorneys'
fees, accounting fees and printing expenses and consent solicitation expenses.

   
         The fees and expenses incurred by USAT in connection with the Merger
and the related transactions described in this Consent Solicitation
Statement/Prospectus are expected to be approximately $_______________,
consisting of $__________ in legal fees and disbursements, $__________ in
expenses related to the Registration Statement, $__________ in printing
expenses, $__________ in Exchange Agent costs, $__________ in consent
solicitation fee and costs (including mailing costs) and $__________ in
miscellaneous costs.  The fees and expenses of U.S. Drug are expected to be
approximately $___________, consisting of $__________ in fee and disbursements
to Whale

miscellaneous costs.
    

CERTAIN TAX CONSEQUENCES

   
         Rosenman & Colin, LLP, special counsel to U.S. Drug, has delivered an
opinion to U.S. Drug as to the tax consequences of the Merger to the U.S. Drug
Minority Stockholders and U.S. Drug, a copy of which opinion is filed as an
exhibit to the Registration Statement.  Gold & Wachtel, LLP, general counsel to
USAT, has reviewed the opinion, has advised the USAT Board orally that it
concurs therein and has advised the USAT Board orally as to the tax
consequences of the Merger to USAT and the USAT stockholders.

         Such firms concur that the Merger, pursuant to which the U.S. Drug
Minority Stockholders will receive shares of the USAT Common Stock, meets the
statutory requirements of a tax-free reorganization as a statutory merger
within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal
Revenue Code of 1986, as amended (the "Code").  Management has also been
advised that the right on the part of the U.S. Drug Minority Stockholders to
receive a portion of the Special Payment, within one year of the Effective Date
(see "The Terms of the Transaction-Special Payment"), as provided in the Merger
Agreement, will constitute "boot".  As such, a U.S. Drug Minority Stockholder
could recognize gain in connection with the Merger, but in an amount not in
excess of the sum of money derived from such boot.  Management has also been
advised that the value of the right to receive the boot is too speculative to
permit the value of such right to be ascertainable at the time the Merger
becomes effective so long as no agreement with a development partner has been
executed, which agreement provides for an advance cash payment to U.S. Drug,
Acquisition Corp. as its successor or USAT.  There can be no assurance that any
such agreement will be executed or, if executed, that it would provide for a
payment that would constitute a Special Payment.  Accordingly, in the opinion
of such counsel, the right to receive the boot will not produce any tax
consequences upon the Effective Date, but any proceeds derived from such right
could be a taxable event at such time as any proceeds may be actually received.
    

         In the event that the payment of the boot has the effect of a
dividend, each U.S. Drug Minority Stockholder who realizes gain on the exchange
of stock will treat as a dividend such an amount of the gain recognized as is
not in excess of his, her or its ratable share of the undistributed earnings
and profits of U.S. Drug, and possibly of USAT, accumulated after February 28,
1913, and the remainder, if any, of the gain will be treated as a gain from the
exchange of property.  If a U.S. Drug Minority Stockholder realizes no gain on
the overall transaction, the boot received by him will not be treated as a
dividend.





                                       71
<PAGE>   77
         At this time, neither U.S. Drug prior to the Merger nor USAT will have
such undistributed earnings and profits through March 31, 1996.  However,
although it is unlikely, it is possible that such earnings and profits could be
created in the subsequent period so as to give rise to dividend treatment.

   
         In any event, management has been further advised that, based on
current judicial and Internal Revenue Service ("IRS") guidelines, the receipt
of boot by non-controlling public stockholders in the situation presented
should not cause such boot to be considered to have the effect of a dividend
whether or not there are earnings and profits present.  Accordingly, any cash
boot received should be taxed as a gain on the sale of the shares of the
Minority U.S. Drug Common Stock and, if there is no gain on the overall merger
transaction, no taxable gain will result.  A tax loss will not be recognized.
    

         In summary, subject to the effect of the receipt of boot as discussed
in the following paragraph, in the transaction governed, as indicated, by
Sections 368(a)(1)(A) and 368(a)(2)(D) of the Code; (a) no gain or loss will be
recognized by the U.S. Drug Minority Stockholders upon the receipt of the USAT
Common Stock in exchange for the Minority U.S. Drug Common Stock; (b) the tax
basis of the USAT Common Stock received by the U.S. Drug Minority Stockholder
will be the same as the tax basis of the Minority U.S. Drug Common Stock
surrendered; (c) the holding period, for federal income tax purposes, of the
USAT Common Stock received by the U.S. Drug Minority Stockholders will, in the
hands of such stockholders, include the holding period of the shares of the
Minority U.S. Drug Common Stock exchanged therefor, provided that such Minority
U.S. Drug Common Stock was held as a capital asset in the hands of such
stockholders on the Effective Date; and (d) a U.S. Drug Minority Stockholder
receiving cash in lieu of a fractional share will recognize a gain for federal
income tax purposes to the extent of the cash received in excess of the tax
basis of the fractional share.

   
         If cash boot is received by a Minority U.S. Drug Stockholder, a gain
(but not a loss) will be recognized in an amount equal to the lesser of the
stockholder's gain on the overall merger transaction or the amount of the boot.
As indicated, if there is no overall gain, no tax liability will arise.  Also,
if cash boot is received, the tax basis of the USAT Common Stock will be the
same as the tax basis of the Minority U.S. Drug Common Stock surrendered,
decreased by the amount of any money (boot) received, and increased by the
amount, if any, which was taxable as a dividend or gain recognized on such
exchange.
    

         There should be no federal income tax consequences to existing holders
of the USAT Common Stock or to USAT or U.S. Drug.





                                       72
<PAGE>   78
         No rulings have been, or will be, requested from the IRS with respect
to any of the matters described above.

   
         The foregoing is not intended as an alternative to individual tax
planning.  Accordingly, each U.S. Drug Minority Stockholder should consult his,
her or its own tax advisor concerning the foreign, federal, state, local or
other tax consequences of the Merger as they relate to the stockholder's
particular circumstances.  There can be no assurance that some or all of the
positions taken by the parties to the reorganization will not be challenged by
the IRS and that the IRS will not prevail in such challenge.
    

         THE FOREGOING CONSTITUTES ONLY A GENERAL DESCRIPTION OF CERTAIN OF THE
FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTION TO THE U.S.  DRUG MINORITY
STOCKHOLDERS, WITHOUT CONSIDERATION OF THE PARTICULAR FACTS AND CIRCUMSTANCES
OF EACH STOCKHOLDER'S SITUATION.

TRADING IN THE U.S. DRUG COMMON STOCK

         If the Merger is consummated, trading in the U.S. Drug Common Stock
will cease on the Effective Date; the registration of the U.S. Drug Common
Stock under Section 12(b) of the Exchange Act will be terminated; and the U.S.
Drug Common Stock will be deleted from the Pacific Stock exchange.

RESALE OF USAT SECURITIES

   
         The shares of the USAT Common Stock to be issued to the U.S. Drug
Minority Stockholders pursuant to the Merger Agreement will be freely
transferable under the Securities Act, except for shares issued to any person
who may be deemed to be an "underwriter" within the meaning of Rule 145(c)
under the Securities Act (an "underwriter", for purposes of the Rule, is
generally an affiliate of U.S. Drug, i.e., a person who as a result of an
officership, a directorship or his, her or its beneficial ownership of shares
of the U.S. Drug Common Stock was deemed to be a controlling person with
respect to U.S. Drug).  Such an underwriter may only transfer shares of the
USAT Common Stock issued in the Merger pursuant to an effective registration
statement or when the proposed transfer is otherwise in compliance with Rule
145(d) under the Securities Act or another exemption from the registration
requirements of the Securities Act.  USAT is the only 10% stockholder of U.S.
Drug and its shares will be cancelled if the Merger is consummated.  The only
person who is currently a director or an executive officer of U.S. Drug will
receive shares of the USAT Common Stock as a result of the Merger is Michael S.
McCord who will receive _____ shares of the USAT Common Stock for his _____
shares of the Minority U.S. Drug Common Stock.  As indicated under "USAT
Principal Stockholders," Peter M. Mark is the only director or executive
officer of USAT who will receive shares of the USAT Common Stock as a result of
the Merger.  Mr. Mark will receive _____ shares of the USAT Common Stock for
his 15,500 shares of the Minority U.S. Drug Common Stock.  USAT will instruct
its transfer agent to implement all applicable restrictions on transfer with
respect to Messrs. McCord's and Mark's shares or any person who may later be
deemed to have been an affiliate of U.S. Drug, of which person USAT currently
has no knowledge.

<PAGE>   79
   
         Under Rule 145(d), an affiliate of U.S. Drug who receives shares of
the USAT Common Stock will be permitted to sell a limited number of shares
provided such sale is made in compliance with paragraphs (c), (e), (f) and (g)
of Rule 144 under the Securities Act, i.e., USAT's securities must continue to
be registered under Section 12 of the Exchange Act; USAT has to have filed all
reports required to be filed under Section 13 of the Exchange Act during the 12
months preceding the date of such proposed sale; the total number of shares
sold by the affiliate during the three-month period immediately preceding the
date the affiliate places his, her or its order to sell may not exceed the
greater of 1% of the shares which are shown as outstanding in the most recent
report or statement published by USAT or the average weekly reported trading
volume of the USAT Common Stock during the four calendar weeks preceding the
sale; the sale is conducted in a "brokers' transaction" or is made directly to
a "market maker" (as those terms are defined in Section 4(4) of the Securities
Act and Section 3(a)(38) of the Exchange Act, respectively); and the affiliate
selling the securities does not solicit or arrange for the solicitation of
orders to buy the securities in anticipation of, or in connection with, such
transaction, or make any payment in connection with the offer or sale of the
securities to any person other than the broker who executes the order to sell
the securities.  In addition, if the person is not an affiliate of USAT at the
time of the proposed sale and has been the beneficial owner of the USAT Common
Stock for at least two years and USAT is then current in filing its periodic
reports under Section 13 of the Exchange Act, or if the person is not an
affiliate of USAT at the time of the proposed sale and has not been for a
period of three months prior thereto and has been the beneficial owner of the
USAT Common Stock for at least three years, such person can sell pursuant to
the exemption of Rule 145(d).
    


                    MATERIAL CONTACTS OF USAT WITH U.S. DRUG

U.S. DRUG RELATIONSHIP WITH USAT

         From January 1992 until January 1993 USAT conducted U.S. Drug's
business operations.  Effective as of January 1, 1993, USAT transferred all of
its drug testing assets, including cash amounting to $11,626 and hard assets
valued at their carrying value of $437,060 and intellectual property rights
associated with the drug testing operations, to U.S. Drug for 3,500,000 shares
of the U.S. Drug Common Stock.  USAT also granted U.S. Drug a sublicense with
respect to the USN technology.

   
         As of June 30, 1996, 67.0% of the outstanding shares of the U.S. Drug
Common Stock was held by USAT.  James C. Witham, Chairman of the Board, Chief
Executive Officer and a director of U.S. Drug, was also the Chairman of the
Board, the President, the
    




                                       74
<PAGE>   80
   
Chief Executive Officer and a director of USAT until April 18, 1996.  Karen B.
Laustsen, a director of U.S. Drug, was an Executive Vice President and a
director of USAT until April 18, 1996.  Gary S. Wolff, the Treasurer, the Chief
Financial Officer, the Chief Accounting Officer and a director of U.S. Drug, is
the Treasurer, the Chief Financial Officer and the Chief Accounting Officer of
USAT and, prior to September 26, 1995, was a director of USAT.  Glenn A.
Bergenfield and William DiTuro, also directors of U.S. Drug until November 15,
1995, were directors of USAT prior to September 26, 1995.  Michael J. Witham
was a director of U.S. Drug and a Vice President of USAT prior to September 26,
1995.  On May 31, 1996, Robert Stutman, the Chairman of the Board, the Chief
Executive Officer and a director of USAT since April 18, 1996, Linda H.
Masterson, the President and Chief Operating Officer of USAT since May 13, 1996
and a director of USAT since September 26, 1995, and Michael S.  McCord, a
consultant to the USAT Board of Directors and a former member of the Committee,
were elected directors of U.S. Drug, with Mr. Stutman also being elected as
Chairman of the Board of U.S. Drug and, effective August 1, 1996, Ms. Masterson
as the President of U.S. Drug.  All of the foregoing persons except Messrs.
Bergenfield, DiTuro and McCord were or are employees of USAT and all are
securityholders of USAT.  See "Summary-Recent Developments," "USAT Management,"
"USAT Principal Stockholders" and "U.S. Drug Principal Stockholders."
    

LOANS FROM U.S. DRUG TO USAT

   
         During fiscal 1995, U.S. Drug made short-term loans to USAT in the
amount of $488,519.  At March 31, 1996, the notes receivable from USAT to U.S.
Drug were in the amount of $282,295.  The USAT notes were secured by a pledge
of USAT's shares of the U.S. Drug Common Stock.  The loans were evidenced by
notes which became due on December 31, 1995, which maturity date was extended
to June 30, 1996, and bore interest at the rate of 8% per annum.  The loans
carried interest rates in excess of those available to U.S. Drug on short-term
money market investments.  USAT repaid the indebtedness to U.S. Drug in June
1996 and authorized the extension of a loan to U.S. Drug in the principal
amount of $500,000, which will bear interest at the rate of 8% per annum and
will be due December 31, 1996.  The pledge of USAT's shares of the U.S. Drug
Common Stock was released.
    

MANAGEMENT SERVICES AGREEMENT

         On April 1, 1993, U.S. Drug and USAT entered into a formal Management
Agreement, pursuant to which USAT's fee for management and administrative
services to U.S. Drug was to be computed at ten percent of U.S. Drug's annual
net sales, with a minimum annual fee of $300,000.  In July 1993, U.S. Drug and
USAT entered into an amended Management Agreement, effective retroactively to
April 1, 1993, pursuant to which the fee for management and





                                       75
<PAGE>   81
   
administrative services provided to U.S. Drug by USAT is a fixed annual fee of
$420,000, plus three percent of U.S. Drug's annual gross sales.  Because U.S.
Drug has no sales to date, it has always paid the minimum fee under the
Management Agreement.  The term of the amended agreement is five years which
commenced April 1, 1993.  Given the related industry experience of USAT
management, the immediate availability of USAT personnel and belief of the
management of U.S. Drug that the terms offered by USAT are fair and reasonable,
U.S. Drug did not investigate alternative management services providers.  The
fee charged by USAT for its management services was determined arbitrarily by
its Board of Directors after taking into consideration the anticipated
diversion of USAT resources required to provide such services to U.S. Drug,
both in terms of employee time and allocated overhead costs.  The arbitrary
formula used by USAT to determine the fee was 50% of the sum of USAT's
executive, accounting and clerical salaries, fringe benefits and related
expenses.  The services provided to U.S. Drug by USAT pursuant to the
Management Agreement include management, administrative, accounting and other
financial services and advice, including, without limitation, the services
currently performed by the Treasurer of U.S. Drug (who is also the Treasurer of
USAT), for which he is not directly compensated by U.S. Drug; services relating
to U.S. Drug's financial and banking relationships; services relating to the
preparation of financial statements, budgets, forecasts and cash flow
projections; cash management advice; and other miscellaneous services and
advice.

         Since July 1992, four former members of USAT's senior management,
James C. Witham, Gary S. Wolff, Karen B. Laustsen and Michael J.  Witham (until
September 26, 1995), were the primary persons involved in the provision of
services to U.S. Drug under the Management Services Agreement.  Because of the
resignations of Mr. Witham and Ms. Laustsen on April 18, 1996, the resignation
of Mr. Wolff on July 3, 1996 and the elections of Robert Stutman and Linda H.
Masterson (effective May 13, 1996) as described under "Summary-Recent
Developments", Mr. Stutman and Ms. Masterson have substituted for Mr. Witham,
Ms. Laustsen and Mr. Wolff in performing these services on behalf of USAT,
although the former provided assistance until May 31, 1996 and Mr. Wolff
continued to assist USAT in providing services to U.S. Drug until July 3, 1996.
Effective that date, Joseph Bradley was elected Treasurer of both U.S. Drug and
USAT so he is now performing Mr. Wolff's services as the Treasurer described in
the preceding paragraph.  The management of U.S. Drug believes that the
Management Services Agreement with USAT is fair and reasonable and that its
costs would be greater if it had to obtain such services from an unaffiliated
party with commensurate industry experience, if available, or maintain the
internal staff required to provide such services itself.

         USAT was incorporated under the laws of Delaware on April 15, 1987 to
design, manufacture and market instruments which measure blood alcohol
concentration by breath sample and analyzation.  USAT subsequently expanded its
business operations through the following acquisitions or the creation of new
subsidiaries:

   
         1.  On January 24, 1992, USAT and the USN entered into a ten-year
non-assignable agreement granting USAT a partial exclusive patent license to
products for drug testing in the United States and certain foreign countries.
Effective January 1993, USAT granted a sole and exclusive sublicense to U.S.
Drug, then a newly-incorporated wholly-owned subsidiary of USAT, which
subsidiary assumed all of USAT's rights and obligations under the foregoing
license.  Pursuant to the sublicense, U.S. Drug is developing proprietary
systems that will test for drug use.  In October and November 1993, U.S. Drug
had a public offering of the U.S. Drug Common Stock.  As of June 30, 1996, USAT
owned 67.0% of the U.S.  Drug Common Stock.

         2.  In June 1988, Good Ideas Enterprises, Inc., a Texas corporation
("Good Ideas Texas"), began the manufacture and shipment of toys.  In June
1992, a subsidiary of USAT acquired a 55% interest in Good Ideas Texas.  In
December 1993, Good Ideas was incorporated in Delaware and Good Ideas Texas was
merged with and into Good Ideas, of which USAT thereafter continued to own 86%
until Good Ideas had a public offering of the Good Ideas Common Stock in March
and April 1994.  As of June 30, 1996, USAT owned 60.8% of the Good Ideas Common
Stock.
    

         3.  In September 1995, ProActive, a wholly-owned subsidiary
incorporated in June 1995, entered the human resource provider business.

         4.  In March 1995, USAT acquired Alconet, Inc., a company engaged in
the computer software networking business which has developed an alcohol
testing network to upload test results and information from various alcohol
breath testing devices.

   
         5.  On May 21, 1996, the Company completed its acquisition of RSA, a
provider of corporate drug-free work place programs.  Since January 1996, RSA
has been designing policies and programs for the ProActive subsidiary.
    

         In November 1992, USRR, then a newly-incorporated wholly-owned
subsidiary of USAT, acquired the assets of a company and began to manufacture
and market floor covering products for office and industrial use from used
truck and bus tires.  Such operations were discontinued on April 30, 1996 when
the assets of





                                       77
<PAGE>   83
USRR were sold.  See the section "Subsidiaries-U.S. Rubber Recycling, Inc."
under this caption "Business of the Company."

         USAT intends to merge ProActive with and into RSA.  If the Good Ideas
Merger is consummated and the Merger is consummated then USAT intends to merge,
Acquisition Corp. RSA and all other subsidiaries which are not sold or
liquidated into USAT and operate thereafter through three divisions, one
conducting alcohol testing operations, one conducting drug testing operations
(if and when the products are developed) and the third conducting human
resource provider/developer of substance abuse programs.  USAT also intends to
seek USAT stockholder approval for a new name that will reflect the combined
operations. 

ALCOHOL TESTING MARKET

         USAT manufactures, markets and distributes alcohol testing detection
equipment directly to law enforcement and correctional facilities, various
industrial companies, medical and clinical facilities, alcohol treatment
centers and emergency rooms, as well as individual consumers.  Its current
product line encompasses three distinct alcohol testing techniques for degrees
of accuracy and admissability in court proceedings.

         Evidential quality equipment, with the exception of the Mobile Alcohol
Collection System ("MACS"), is approved by the United States Department of
Transportation (the "DOT") for use by law enforcement agencies and industry.
The information derived from the equipment is used in court trials.


         Alcohol screening devices are used by correctional facilities,
industrial companies, hospitals, nuclear agencies, companies in the maritime
industry and law enforcement agencies to gather human data on blood alcohol
levels.  Although such data (from breath) is not generally admissible as court
evidence, it is used to indicate alcohol presence.  These screening devices
determine the presence of alcohol and its approximate blood level.  They are
less accurate and reliable than evidential quality devices, which are useable
in legal proceedings in contrast to the screening devices.

         USAT purchases the raw materials and parts for its products from
various suppliers which deliver them to USAT for assembly, packaging and
distribution.  These raw materials are primarily glass, plastic containers and
certain mechanical parts, all of which are readily available from many
suppliers.

ALCOHOL TESTING PRODUCTS

         USAT's product line includes evidential and screening devices and
testing services which are marketed and sold in various ways.  See the section
"Alcohol Testing Marketing" under this caption "Business of the Company."

(1) EVIDENTIAL DEVICES

         Alco-Analyzer

         USAT designed and developed this product as a gas chromatograph
alcohol testing device that determines blood alcohol levels by use of breath
samples with precision and accuracy to be used as evidence in legal
proceedings.  USAT's three models have been approved by the DOT as evidential
breath alcohol testing instruments; however, only one--the Model 2100--is
currently manufactured by USAT.  Such model is used to analyze blood, breath
and urine specimens to determine levels of ethyl alcohol and is described as
follows:

   
         Model 2100 - Enhanced electronics and software create an easy to use
instrument which can be networked to a central location for downloading data.
Testing information and results are displayed on a color computer monitor and
are printed on a multi-part carbonless form.
    

         USAT, to management's knowledge, is the only manufacturer of a gas
chromatograph breath testing device designed specifically for ethyl alcohol
determinations using an inert carrier gas.  Management believes that gas
chromatography is recognized as an ideal, convenient and reliable method for
determining and identifying chemical substances within a compound.

         Mobile Alcohol Collection System (MACS)

         USAT manufactures a Mobile Alcohol Collection System ("MACS") device
used to collect a breath sample for future analysis.  The MACS device contain a
silica gel compound within a glass vial accompanied by collection and waste
bags which insure the gathering of a proper sample flow through the vial.  The
vial is then sent to an independent certified laboratory where the alcohol is
extracted from the silica gel and analyzed on a gas chromatograph to determine
the exact blood alcohol content.  Management is unaware of any product which
currently competes with the MACS device.

(2) SCREENING DEVICES

         Screening devices are designed to determine the presence and
approximate level of alcohol in a person's blood via his or her breath and
whether further testing is warranted.





                                       79
<PAGE>   85
         The Alco-Breath Tubes ("ABT") are disposable alcohol breath glass vial
testers containing yellow bands comprised of silica gel treated with a reagent
solution.  Testing begins with breath blown into a balloon which is then
attached to the glass vial into which the sample flows.  If alcohol is present
within the subject's breath, a chemical reaction occurs within the gel changing
the yellow bands to green.  Measurement results are determined by the extent of
color change.  USAT manufactures four variations of the Alco-Breath Tubes
specifically designed for various applications of alcohol breath testing.

(3) CALIBRATION DEVICES

         USAT manufactures two devices which are used to calibrate and check
alcohol testing instruments made by both USAT and its competitors for continued
accuracy.  The devices are designed to simulate the breath of a person who has
been drinking alcohol.  The standard alcohol solutions used in these
calibration devices are produced by USAT in its own certified laboratory.

         (a)     Alco-Simulator and Alco-Simulator 2000

         The Alco-Simulator and its newer 2000 model are approved by the DOT as
calibrating devices for evidential breath testing instruments.

         (b)     Alco-Equilibrator

         The Alco-Equilibrator operates on the same general principle as the
Alco-Simulator, but is less accurate and may only be used for calibrating
non-evidential breath testing instruments.

ALCOHOL TESTING MARKETING

         The Alco Analyzer, the Mobile Alcohol Collection System and the Alco
Breath Tubes represent 90% of USAT's current sales volume of its alcohol
testing products in domestic and international markets.  Sales are made
directly by USAT's sales representatives.  USAT markets its products at trade
shows, conventions and through print advertisements.

         USAT currently segments its merchandise into four market areas:

                          Law Enforcement/Correctional
                          Industrial
                          Medical/Clinical
                          Drug and Alcohol Testing Services





                                       80
<PAGE>   86
(1) LAW ENFORCEMENT/CORRECTIONAL

         USAT markets and sells the Alco-Analyzer and the Mobile Alcohol
Collection System ("MACS") to law enforcement agencies for evidential testing
purposes.

         Screening devices and Alco-Breath Tubes ("ABT") are generally used for
roadside screening to determine probable cause for further breath testing by
evidentiary quality testing equipment.

         USAT markets and sells breath alcohol screening devices to the
correctional and institutional market, which includes probation and prison work
release programs.

(2) INDUSTRIAL

         USAT is marketing and selling both evidential quality and screening
devices to several companies for blood alcohol testing of employees.

         In February 1994, the DOT published its final rule implementing the
federal act which mandates alcohol testing within the transportation industry.
The final rule requires alcohol testing solely through the use of breath
samples.  These enactments have a direct bearing on the USAT's gas
chromatography products, which the DOT had previously approved as evidential
breath alcohol testing instruments.  USAT has designed the Alco-Analyzer 2100
to specifically meet the needs of this market.  Its marketing strategy includes
sales, leases and placements of the instrument with a cost per test charge.

         USAT, as part of its current business strategy, intends to capitalize
upon the DOT's rules for mandatory alcohol testing within the transportation
industry.  The final rule, which became effective in January 1995 as to the
larger transportation companies and, in January 1996, as to the balance,
affected nearly 8,000,000 employees who are engaged in safety-sensitive
positions in the transportation industry by requiring them to be tested for
alcohol on DOT-approved breath testing devices.  Mandatory pre-employment
screening, however, is not required by the DOT rule.  USAT's Alco-Analyzer
series and, in particular, its Model 2100 meet the DOT's standard.  In December
1994, USAT entered into two agreements with major testing laboratories, Corning
Clinical Laboratories Inc., formerly Metpath Inc., and Lab. Corp., formerly
National Healthcare Laboratories Incorporated, for placement of approximately
700 units of its Model 2100 at the respective laboratory's, collection sites
with remuneration to USAT on a per test basis.  These two agreements, as well
as others with smaller customers, have terms ranging from three to five years.





                                       81
<PAGE>   87
         USAT has also sold its ABT and MACS devices to the maritime industry
which must conform to government regulations established to test alcohol blood
levels of ship operators.  Its testing devices and equipment have been
purchased by other private and public companies which include alcohol testing
in their substance abuse testing programs.

   
         USAT also intends to pursue the non-regulated market for alcohol
testing where approximately 93% of the American work force is employed.
Management is of the opinion that the MACS and the ABTs can increasingly be
sold to commercial companies which, recognizing the adverse impact of alcohol
abuse on the productivity of their employees, wish to institute on-site testing
programs.  In order to implement this program, management believes that the
ABTs must be reformatted and preferably DOT approval should be obtained for
both the MACS and the ABTs.  Although management believes that this
non-regulated market is a market with great potential, there can be no
assurance that USAT will derive significant revenues from this market.
    

(3) MEDICAL/CLINICAL FACILITIES

         USAT sells its alcohol screening devices to the medical and clinical
markets for testing of patients in alcohol treatment facilities and those who
are brought to hospital emergency rooms under suspected influence of alcohol.
USAT continues to expand its sales of screening devices and the gas
chromatograph into this market to provide instantaneous and accurate on-site
testing procedures for breath alcohol analysis.

(4) DRUG AND ALCOHOL TESTING SERVICES

   
         Biochemical Toxicology Laboratories ("Biotox") operates as a division
of USAT and also services the needs of U.S. Drug, USAT's drug testing
subsidiary.  Biotox is certified as a Clinical Laboratory by the State of
California and also possesses specific state licenses for alcohol and methadone
analysis.  It is engaged in drug and alcohol testing for many area police
departments, detoxification centers, coroners departments and corporations and
functions within USAT's facilities maintaining state of the art
instrumentation.  Management is of the opinion that, if Biotox obtained certain
regulatory approvals, it could be used by the alcohol testing, the drug testing
and the human resource provider operations of the Company to a greater extent
and, thereby enable the Company to realize greater revenues.  There can be no
assurance that these governmental approvals will be obtained or that the
Company will derive greater revenues as a result of the efforts of Biotox.
    


                                       82
<PAGE>   88
LIABILITY INSURANCE

         USAT maintains liability insurance of $1,000,000, together with an
umbrella policy providing coverage of $3,000,000, to protect the Company
against legal action related to injury resulting from product failure, whether
such product is offered by USAT or a subsidiary thereof.

COMPETITION

         Alcohol Testing

   
         The substance abuse detection equipment industry is highly
competitive.  Although USAT's Alco Analyzer 2100 is, to management's knowledge,
the only DOT-approved evidential alcohol breath testing instrument utilizing
gas chromatography, it still competes with other substance abuse detection
techniques developed by other companies.  USAT competes with small companies
which also offer alcohol testing equipment such as CMI Inc., Intoximeters, Inc.
and Lifeloc, Inc.  Although all of these competitors are believed currently to
have greater revenues than USAT from sales of alcohol testing devices,
management is of the opinion that only CMI, Inc., which is a subsidiary of
MPD/MPH, may have greater financial resources than USAT.  In addition, several
companies, including Roche and STC, Inc., offer an on-site screening saliva
based alcohol test.  Roche has, and several of these companies may have,
greater revenues and financial resources than the Company.  Although USAT
believes that its product and service quality, combined with its experienced
personnel, will offer it a competitive edge in marketing its products and
services, there can be no assurance that USAT will be able to compete
successfully with larger companies which have greater financial resources
available to them to develop and offer an array of substance abuse detection
products, nor is there any assurance that other companies will not enter the
marketplace and present additional competition for USAT and its products.
    

         Drug Testing

   
         The Company has not received any revenues from U.S. Drug because its
products are still in the developmental stage.  Currently U.S.  Drug is
developing two products which screen for the presence of drugs of abuse, one
which utilizes flow immunosensor technology with urine samples as a medium of
testing and another which utilizes flow immunosensor technology with saliva
samples as a medium of testing.  Only the saliva sampling system is currently
being developed; however, if this product is successfully developed, U.S. Drug
intends to use the technology to complete the urine sample system.  The
technology in development will specifically test for five commonly used drugs
of abuse: cocaine, opiates (heroin, morphine and codeine),
    


                                       83
<PAGE>   89
   
phencyclidine hydrochloride (PCP), amphetamines (including methamphetamines)
and tetrahydrocannabinol (THC, marijuana).  If the products are developed, U.S.
Drug will compete with many of the companies of varying size that already exist
or may be founded in the future which utilize urine samples as a medium of
testing.  U.S. Drug will face competition from at least eight major
pharmaceutical companies providing substance abuse screening methods: (1)
enzyme-multiplied immunoassay technique (EMIT) manufactured and distributed by
Syva; (2) radioimmunoassay (RIA) manufactured and distributed by Roche and
others; (3) thin layer chromatography (TLC) manufactured and distributed by
Marion; (4) a fluorescence polarization immunoassay (FPIA) manufactured by
Abbott, and other immunoassay tests provided by (5) Editek; (6) Hycor; (7)
Princeton, and (8) Biosite.  Almost all of these companies (i.e., Syva, Roche,
Marion, Abbott, Editek, Hycor, Princeton and Biosite) have substantially
greater financial resources available to them than does U.S. Drug to develop
and to market their products.

     Management believes that saliva sample testing is unique in that, to
management's knowledge, no company is currently offering a substance abuse
detection method using saliva samples as a medium on an "on-site" basis.
However, U.S. Drug has been advised that such a product is under development by
other companies and, accordingly, there can be no assurance that such a product
will not be offered by a competitor.  In addition, even if no such product is
developed, U.S. Drug anticipates, as indicated above, competition from other
substance abuse detection methods such as Syva's EMIT, Roche's RIA, Marion's
TLC, Abbott's FPIA methods, and other immunoassay tests provided by Editek,
Hycor, Princeton and Biosite.  U.S. Drug's market research to date has
indicated a greater market potential for a saliva sample portable testing
instrument for use in detecting drugs of abuse by law enforcement agencies,
correctional facilities, hospitals and other medical facilities than a urine
sample instrument.  However, because of the expected limited life cycle of a
saliva specimen, the use of this product in other potential markets may be
limited.

      If U.S. Drug successfully develops first its saliva sample testing method
and second its urine sample testing method, as to which there can be no
assurance, it is not certain whether U.S. Drug will have the financial
resources to compete successfully with other companies which have greater
financial resources available to them.  Depending on the progress in the drug
testing research and development program (including the current feasibility
study), U.S. Drug may at a later date seek a major pharmaceutical or other
company to assist in the development program and, depending on the financial
arrangements to be negotiated, such development partner may seek marketing
rights to the products when and if successfully developed.  Although such a
partner may reduce certain current expenditures, it may later, by
    


                                       84
<PAGE>   90
   
assuming marketing rights, reduce prospective revenues to U.S. Drug.  Because
of the stage of development of the product and the fact that no search or
negotiations are currently being conducted, management believes that it is
currently too speculative to anticipate U.S. Drug's competitive position based
on the presence of a marketing and/or product development partner.

     U.S. Drug's management currently anticipates that U.S. Drug will submit
its five-panel screening assay to the Food and Drug Administration (the "FDA")
late in 1997 at the earliest and that U.S. Drug will commence marketing its
products six months to a year later.  There can be no assurance as to when U.S.
Drug will submit such assay to the FDA, if at all, as to when the FDA will give
its approval and as to when marketing will commence.
    

         Human Resource Provider

   
         ProActive is a single source service provider, meaning that it is a
provider of both substance abuse testing services and background screening
services.  A single source service provider is a relatively new concept.
Additionally, the Company, through the recent acquisition of RSA, can also
provide customized loss prevention services specifically designed to reduce the
negative effect of workplace substance abuse.  The competition from single
source providers which ProActive currently encounters is primarily from small
local and regional companies.  To management's knowledge, currently there is no
single source provider on a national level, which is what ProActive hopes to
become, and there are no other providers of customized programs and policies
like RSA.  However, Lab Corp., through Med-Express, is currently offering
background screening services to corporations on a limited basis.  Although,
ProActive has experienced personnel in both the drug testing and investigative
arena, there can be no assurance that ProActive will become successful in
marketing its services as a single source provider on a national level.  In
addition, ProActive will face competition from other companies which provide
each of these services separately such as the companies mentioned in the
preceding subsections of this section "Competition" under this caption
"Business of the Company" as it relates to substance abuse testing providers
(including the laboratories which are vendors to ProActive), and local or
regional investigative firms or private investigators (including vendors to
ProActive) as it relates to background investigative services.  Assuming that
the combined RSA/ProActive operations achieve national status as a single
source provider, there can be no assurance that existing or new companies will
not enter the national marketplace to compete with the combined RSA/ProActive
operations.
    


                                       85
<PAGE>   91
         Toy Products

   
         The toy industry is highly fragmented and extremely competitive.
Currently, Good Ideas markets a full line of wooden interlocking log and wooden
block construction playsets which competes primarily with Lincoln Log, a
product manufactured and distributed by Playskool, a division of Hasbro, Inc.
("Hasbro"), one of the five largest toy companies in the United States.  Good
Ideas also markets a line of equestrian toys consisting of plastic horses
ranging in height from five to eleven inches which competes primarily with
products offered by Breyer, Inc., the dominant manufacturer of injection-molded
collectible horses, and Marchon, Inc., a United States importer of
injection-molded toy horses.  Management believes that it offers a high quality
line of wooden log playsets and equestrian toys.  However, there can be no
assurance that Playskool/Hasbro, which has greater financial resources
available to it than Good Ideas, will not attempt to expand its presence in the
wooden log playsets category, nor is there any assurance that other toy
companies will not attempt to enter into this category.  Due to relatively low
barriers to entry in the toy industry, Good Ideas could face competition from a
number of smaller toy companies as well if it were not to be sold or liquidated
by December 31, 1996.
    

RESEARCH AND DEVELOPMENT

   
         During fiscal 1996, the Company spent approximately $1,006,000 on
research and development, including $851,000 expended on development of the
drug testing technology of U.S. Drug.  In fiscal 1995, the Company spent
approximately $1,249,000 on research and development, including $886,000
expended on development of the technology of U.S. Drug.  In fiscal 1994, the
Company spent approximately $948,000 on research and development, including
$728,000 expended on development of the technology by U.S. Drug.
    

PATENTS AND TRADEMARKS

   
         U.S. Drug has rights under three patents, in addition to its rights to
use the USN patent under its sublicense from USAT.  USAT and its other
subsidiaries currently have no patents on the other products of the Company.
The term of the USN patent is set forth in the section "Subsidiaries-U.S. Drug
Testing, Inc." under this caption "Business of the Company" and the terms of
the U.S. Drug patents are 17 years from the date of issuance as set forth in
that section, subject to renewal.  Termination of the Licensing Agreement for
the USN patent, which would occur only on a default by USAT or an invalidation
of the USN patent, would end the Company's rights to develop drug testing
products.  Termination of the other patents or licenses to use the same would
require USAT to make changes to its products which could further delay
development and marketing thereof.
    


                                       86

         The Company has obtained tradenames for its major products.  The
following are the registered trademarks of the Company and have been published
by the U.S. Patent and Trademark Office (the "PTO"):  Alco-Equilibrator(TM),
Sobriety Checkpoint(TM), ABT(TM), Alco-Analyzer(TM), Final Call(TM),
Alco-Equilibrator(TM) and Drug Won't Work Here(TM).  On April 12, 1995, the
Company abandoned the following trademarks: Mobile Alcohol Collection, MACS,
Alco-Report; Alco-Breath Tubes, Alco-Link and Alco-Simulator.  Good Ideas has
registered the trademarks Good Ideas(TM) and Big Bill's Bric Builders(TM) and
the same are published by the PTO.  The Company believes these tradenames
afford adequate protection.  However, there can be no assurance that
infringement claims will not be asserted against the Company in the future.
    

SUBSIDIARIES

(1) U.S. DRUG TESTING, INC.

   
         In October and November 1993, USAT's then wholly-owned subsidiary U.S.
Drug completed an initial public offering of the U.S. Drug Common Stock, which
security trades on the Pacific Stock Exchange.  As of June 30, 1996, USAT owned
3,500,000 of the 5,221,900 outstanding shares of the U.S. Drug Common Stock or
67.0% thereof.
    

         The Company has not received any revenues from U.S. Drug because its
products are still in the developmental stage.  For information relating to
this subsidiary, see "Business of U.S. Drug."

(2) GOOD IDEAS ENTERPRISES, INC.

   
         In February and April 1994, Good Ideas completed an initial public
offering of the Good Ideas Common Stock, which security trades on the Pacific
Stock Exchange.  As of June 30, 1996, USAT owned 2,400,000 of the 3,948,680
outstanding shares of the Good Ideas Common Stock or 60.8% thereof.

         Good Ideas designed, markets and distributes a variety of traditional
toy products for children of various ages.  Its sales historically have been
derived from a line of traditional wooden construction toys.  Good Ideas'
strategy had been to design and develop enduring traditional lines of toys and
to create enhancements to, and extensions of, these toy lines which were
intended to maximize product line sales while minimizing development and

         Good Ideas' principal product line, wooden construction toys, includes
classic interlocking log sets marketed under the trademark Paul Bunyan Log
Builders(TM), themed playsets such as


                                       87
<PAGE>   93
General Custer's Fort Apache(TM), building block sets marketed under the
trademark Paul Bunyan Bloc' Builders(TM) and brightly-painted, multi- colored
combination log and block sets marketed under the trademark Paul Bunyan Wood
Builders(TM).  In addition to its line of wooden construction toys, it markets
one other line of traditional toys.  Since March 1993, it has shipped a line of
equestrian toys comprising of various styles and sizes of flocked plastic
horses and related accessories marketed under the trademark Black Beauty and
Friends(TM).

   
         Since it first commenced shipping products in June 1988, Good Ideas'
principal customers have been mass merchandisers, such as Toys R Us, Inc.
("Toys R Us"), Wal-Mart Stores, Inc., and J.C. Penney Company, Inc., and
wholesale clubs, such as Costco Wholesale Corporation, Pace Membership
Warehouse, Inc. and BJ's Wholesale Club, Inc.  Its current domestic
distribution network also includes high-end specialty retailers, such as F.A.O.
Schwartz and Imaginarium.

         Toys R Us, the major customer of Good Ideas, has not been placing
orders for Good Ideas' toy products.  The customer has attributed its reduction
in orders to its large inventories and declining sales and customer traffic.
Management believes that other manufacturers in the toy industry are currently
facing those same problems -- their distributors or retailers to which they
sell have large inventories of products and declining sales and customer
traffic.  In addition, management believes that many retailers are minimizing
their number of vendors, which has the result of squeezing out the smaller
companies with their limited product lines.  See "The Company's Management's
Discussion and Analysis of Financial Condition and Results of
Operations-Results of Operations-Good Ideas Enterprises, Inc."
    

         Since July 1992, USAT has provided, and continues to provide, certain
management and administrative services to Good Ideas.  These services included
management and financial advice; maintenance of financial books and records and
preparation of financial statements, budgets, forecasts and cash flow
projections; services relating to banking relationships; payment of accounts
payable and payroll; collection of accounts receivable and credit analysis;
order processing; import processing; cash management; and other miscellaneous
services and advice.  From July 1992 through March 1993, the fee payable to
USAT for these services was computed on a fixed monthly charge of $25,000.  In
April 1993, Good Ideas and USAT entered into a formal Management Agreement,
pursuant to which the fee for such services was computed at ten percent of
annual net sales.

         In December 1993, Good Ideas and USAT entered into a Management
Services Agreement, effective retroactively to October 1, 1993, pursuant to
which the fee for management and administrative services provided by USAT is
computed on a fixed


                                       88
<PAGE>   94
monthly fee of $25,000, plus five percent of annual gross sales in excess of
$5,000,000.  The fee charged by USAT for its management services was determined
arbitrarily by its Board of Directors after taking into consideration the
anticipated diversion of USAT resources required to provide such services, both
in terms of employee time and allocated overhead costs.  Pursuant to the
Agreement, the term, which initially was to expire on September 30, 1994, has
been automatically renewed so that it is now scheduled to expire on September
30, 1996.  The agreement, however, provides for automatic one-year renewals
unless terminated by Good Ideas upon six months' notice prior to the
commencement of any renewal term or by USAT at least 12 months prior to the
commencement of any renewal term.  In view of the USAT Board's decision on
February 26, 1996 to sell or liquidate Good Ideas (see the succeeding
paragraph), the Board suspended management fees to USAT retroactive to January
1, 1996.

   
         USAT has also filed a Registration Statement on Form S-4, File No.
333-3734, under the Securities Act to register shares of the USAT Common Stock
to be issued to the minority stockholders of Good Ideas upon the consummation
of a merger of Good Ideas with and into a wholly- owned subsidiary of USAT.  As
indicated under "The Merger and Related Matters-Reasons for the Merger and
Approval" the USAT Board of Directors has concluded that the value of the USAT
Common Stock could best be maximized if the Company concentrated its operations
on the USAT alcohol testing segment, the U.S. Drug testing segment and the
related human resource provider business of ProActive and operated the three as
if one corporation.  This action would require sale of the rubber recycling
product business of USRR (see the subsection (4) in this section "Subsidiaries"
under this caption "Business of the Company") and the toy business of Good
Ideas.  In addition, the USAT directors have concluded that, because of the
history of declining revenues and losses in Good Ideas, the necessity to add a
new product line or lines if a turnaround is to be achieved and the problems
generally in the toy industry, it would be difficult to make Good Ideas'
operations profitable within what they considered an acceptable time frame,
assuming that such result could be achieved at all, as to which there can be no
assurance.  For these reasons, the USAT Board authorized on February 26, 1996
management to seek offers from prospective purchasers.  Gary S.  Wolff, the
Treasurer of USAT and Good Ideas until July 3, 1996, has been speaking with
various vendors and customers of Good Ideas as to their interest in acquiring
all or part of Good Ideas.  No formal bid process has been initiated.  To date,
while certain of the vendors have expressed some interest, none has presented
an offer that Mr. Wolff could present to the Board.  His services in this
connection are continuing despite his resignation, for which services he is not
receiving any additional compensation.  See, however, "USAT
Management-Employment Agreements."  There can be no assurance that an
acceptable offer to purchase will be received or as to the terms
    


                                       89
<PAGE>   95
   
of any such offer.  If no acceptable offer is received by December 31, 1996,
the USAT Board will liquidate Good Ideas.

(3) PROACTIVE SYNERGIES, INC./ROBERT STUTMAN & ASSOCIATES, INC.
    

         ProActive, which is a wholly-owned subsidiary of USAT that commenced
operations in September 1995, provides single source services to assist
corporations in their hiring practices ranging from substance abuse testing and
background screening services to total program management.  ProActive's
substance abuse testing services include specimen collections, laboratory
testing and medical review officer services.  Medical review officers review
drug test results to verify that chain-of-custody procedures were followed and
determine if there is an alternative medical explanation for a positive test
result.  ProActive's background investigative services include criminal history
checks, employment verifications, credit checks, reference checks, driving
record checks, workers' compensation history checks, and social security
number, educational and professional license verifications.  ProActive's
services also include physicals and employee assistance programs.  Its total
program management services include establishing a substance abuse policy with
corporations and conducting program audits to ensure regulatory compliance with
such policy.  ProActive's hiring solutions to corporations include the use of
its proprietary computer software which provides ProActive with access to
immediate on-line information.
   
    

   
         On December 14, 1995, USAT and ProActive entered into an agreement
with RSA and Robert Stutman, personally, pursuant to which (1) USAT and
ProActive engaged Mr. Stutman to be their expert spokesman and a consultant
with respect to their drug and alcohol testing businesses; (2) ProActive agreed
to refer customers to RSA for the purpose of RSA providing its services to such
customers, including writing drug testing/background screening policy manuals;
and (3) RSA agreed to refer customers to ProActive.  Prior to forming RSA, Mr.
Stutman was Special Agent in charge of the United States Drug Enforcement
Administration's New York office.  He also currently serves as special
consultant on substance abuse for the CBS News Division.  On December 14, 1995,
pursuant to the agreement, USAT agreed to issue to Mr. Stutman and RSA
three-year Common Stock purchase warrants, each to purchase 200,000 shares of
the USAT Common Stock at $2.00 per share, which was the market price on the
date of grant.  These warrants were issued on December 14, 1995 and April 1,
1996.  The agreement, which had a term of ten years (except the term for the
consulting and spokesperson services by Mr. Stutman was three years), provided
for payment of fees to ProActive based on referrals to RSA and an initial
$100,000 payment by ProActive and varying monthly fees thereafter to RSA.
    


                                       90
<PAGE>   96
   
         As indicated under "Summary-Recent Developments," on April 18, 1996,
Mr. Stutman was elected as the Chairman of the Board and a director of USAT and
designated as its Chief Executive Officer.  See the section "Recent
Developments" under this caption "Business of the Company".  USAT also agreed
in principle to acquire RSA.  On May 21, 1996, the Company completed its
acquisition of RSA and RSA became a 100% owned subsidiary of USAT.  USAT paid
$2,100,000 to the RSA stockholders for their  shares of RSA (including
$1,078,920 paid to Mr. Stutman for his 52.8% of the RSA shares and $721,080
paid to Brian Stutman, son of Mr. Stutman and now Director of Sales and
Marketing of USAT, for his 35.3% of the RSA shares and issued to the RSA
holders an aggregate of 500,000 shares of the USAT Common Stock (including
263,750 shares issued to Mr. Stutman and 176,250 shares to Brian Stutman)
registered under the Securities Act as Acquisition Shares in the January 1992
Registration Statement, and USAT Common Stock purchase warrants expiring May
20, 1999 to purchase an aggregate of 900,000 shares of the USAT Common Stock
(including a warrant to purchase 474,750 shares issued to Mr. Stutman and a
warrant to purchase 317,250 shares issued to Brian Stutman) at $3,125 per
share, which was the fair market value on the date of grant.  USAT also issued
two promissory notes aggregating $400,000 in principal amount (the "RSA Notes")
to two RSA stockholders (one of whom is Mr. Stutman who received a RSA Note for
$239,760 and Brian Stutman received a note for the balance).  The RSA Notes
bear interest at the rate of 7.5% per annum and become due in one year from the
May 21, 1996 closing date.  USAT is required to prepay the RSA Notes if the
gross proceeds received by USAT from the exercises of the USAT Common Stock
purchase warrants after April 17, 1996 exceeds $7,000,000.  The RSA Notes are
secured by all of USAT s tangible and intangible personal property except the
following: (1) USAT s cash and cash equivalents; (2)USAT s securities,
including the stock of its subsidiaries; and (3) certain contracts, including
the license with the USN.  As a result of the acquisition of RSA, the
Consulting Agreement described in the preceding paragraph terminated; however,
the Common Stock purchase warrants described therein remain outstanding, except
that the RSA warrant was distributed to the RSA shareholders, including Mr.
Stutman who received a warrant to purchase 105,500 shares and Brian Stutman who
received a warrant to purchase 70,500 shares.

         During its last three fiscal years ended December 31, RSA's revenues,
income and income per share were as follows:

         Effective December 28, 1995, ProActive also engaged the services of
Patricia Starling, who had been serving as a consultant, as its Vice President
Operations for a two-year term.  Ms. Starling was granted a Common Stock
purchase warrant expiring December 27, 1998 to purchase 20,000 shares of the
USAT Common Stock at $2.00 per share, which was the market price on the date of
grant.  The warrant is currently exercisable as to 10,000 shares and becomes
exercisable as to 5,000 shares on each anniversary date.

         See the section "Property" under this caption "Business of the
Company" for information as to the ProActive and RSA leases.
    

(4) ALCONET, INC.

   
         In March 1995, USAT acquired 100% of the issued and outstanding common
stock of Alconet and all the membership interests of Dakotanet, L.L.C.  As
consideration, USAT issued 782,321 shares of the USAT Common Stock registered
under the Securities Act as Acquisition Shares in the January 1992 Registration
Statement (see "The Merger and Related Matters-Summary of the Terms of the USAT
Common Stock-Acquisition Shares") and valued at $1,564,642.  The acquisitions
have been accounted for as a purchase in the financial statements of the
Company.  In March 1996, USAT settled a dispute with two officers of Alconet
for an aggregate payment of $250,000 and the assignment of certain software to
one of the officers, both of whom then resigned.  Alconet is engaged in the
computer software/networking business.  Alconet has developed an alcohol
testing network to upload test results and information from various alcohol
breath testing devices.  As a cost reduction action, USAT may seek to
consolidate or integrate the Alconet operations with other operations of the
Company; however, there can be no assurance as to the timing or the effect of
such a program.
    

(5) U.S. RUBBER RECYCLING, INC.

   
         In November 1992, USAT purchased the total assets of Adflo
International, Inc. for its then newly formed wholly-owned subsidiary, USRR,
which then began to manufacture floor covering products for office and
industrial use from used truck and bus tires.  These tires were delivered to
USRR's Rancho Cucamonga plant and to an off-site storage facility, where they
were recycled by splitting and cutting the tires and reassembling the recycled
parts into finished products.  Sales were made nationwide through
manufacturer's representatives and distributors.  All manufacturing was
performed in the USRR's then Rancho Cucamonga facility.  USRR ceased operations
on April 30, 1996 when substantially all of its assets were sold as described
in the second succeeding paragraph.
    


                                       92
<PAGE>   98
         USAT acquired the total assets of Adflo International, Inc. for a
total consideration of 185,000 shares of the USAT Common Stock valued at
$196,563.  The transaction was accounted for as a purchase in the financial
statements of the Company.  These shares were part of the Acquisition Shares
registered under the Securities Act in the January 1992 Registration Statement
solely for acquisition purposes (see "The Merger and Related Matters-Summary of
the Terms of the USAT Common Stock-Acquisition Shares").

   
         On April 30, 1996, USRR sold substantially all of its assets to an
unaffiliated buyer for $450,000, $150,000 of which was paid at the closing and
the balance by the delivery of a $300,000 promissory note.  The purchaser also
paid approximately $80,000 in accounts payable of USRR and assumed certain
other liabilities, including USRR's lease (see, however, the section
"Description of Property" under the caption "Business of the Company").  The
sale resulted in a loss of approximately $88,000.  The promissory note is
payable in six annual installments of $50,000, together with interest at a rate
of 7% per annum.  In addition to the annual installments, the promissory note
will be prepaid in an amount equal to 12-1/2% of the buyer's annual gross sales
of USRR products in excess of $1,400,000.  The promissory note is secured by a
first priority security interest in all of the buyer's assets.  USRR is
required to agree, however, to subordinate its security interest to up to
$1,000,000 of institutional financing for the buyer.
    

EMPLOYEES

   
         As of July 31, 1996, the Company had 70 full time employees other than
its officers, 27 engaged in manufacturing, 7 in sales, 7 technical, 6
scientists and 22 in clerical administrative jobs.  The Company has no
collective bargaining agreement with its employees.
    

DESCRIPTION OF PROPERTY

   
         USAT occupies approximately 20,000 square feet office and factory
facilities in Rancho Cucamonga, California under a lease expiring January 31,
1997, which premises are shared with its subsidiaries U.S. Drug and Good Ideas.
This lease includes the option of extending its term for two consecutive
five-year periods.  USAT's subsidiary ProActive occupies approximately 1,640
square feet of office space in Savannah, Georgia under a lease expiring January
2, 1999.  The Alconet subsidiary occupies approximately 1,200 square feet of
office space in Bismark, North Dakota under a lease expiring March 31, 1997.

         Effective August 1, 1996, USAT will sublease approximately 8,500
square feet of office space in Fort Lauderdale, Florida, under a lease expiring
November 30, 2001, which lease grants the
    





                                       93
<PAGE>   99
   
tenant a right to renew for an additional five-year term.  The space will be
utilized as headquarters for Robert Stutman, Chairman of the Board and Chief
Executive Officer of USAT, RSA and ProActive.  RSA's landlord for space in
Dedham, Massachusetts has agreed to a cancellation of RSA's lease.  ProActive
is attempting to sublease the office space described in the preceding
paragraph.  USAT may seek to sublet up to 1,000 square feet of the new space
pending utilization thereof.

         Good Ideas previously occupied approximately 22,000 square feet of
office and factory space in Fort Worth, Texas under a lease which expired
December 31, 1995.  Until April 30, 1996, USAT's subsidiary USRR occupied
approximately 17,000 square feet of office and factory space in Rancho
Cucamonga, California under a lease expiring June 30, 1999.  Pursuant to the
sale of USRR's assets (see the section "Subsidiaries - U.S. Rubber Recycling,
Inc." under this caption "Business of the Company"), the purchaser assumed the
foregoing lease, but the landlord did not release USRR from its obligations.

     In addition to rent, the leases provide for payment of real estate taxes
and other occupancy costs.  For information as to the aggregate rentals paid
during the past three fiscal years and anticipated to be paid in the ensuing
three fiscal years, see Note 13 to Notes to the Company's Financial Statements
elsewhere in this Prospectus.
    

         Management is of the opinion that the leased facilities are currently
adequate and suitable for the Company.

LEGAL MATTERS

         The Company is not a party to any material litigation and is not aware
of any pending litigation that could have a material adverse effect on the
Company's business, results of operations or financial condition.


                             BUSINESS OF U.S. DRUG

GENERAL

   
         U.S. Drug has not produced any revenues because its products are still
in the developmental stage.  U.S. Drug is developing proprietary systems that
will test for drug use, specifically the following five commonly used drugs of
abuse: cocaine, opiates (heroin, morphine and codeine), phencyclidine
hydrochloride (PCP), amphetamines (including methamphetamines), and
tetrahydrocannabinol (THC, marijuana) (collectively the "Drugs of Abuse").  In
January 1992, the USN and USAT signed a ten-year license agreement (the
"License Agreement") covering the exclusive use by USAT of the USN's technology
for the five Drugs
    





                                       94
<PAGE>   100
   
of Abuse and any other drugs that might be added to the National Institute of
Drug Abuse (NDA) list of drugs of abuse.  By an amendment dated March 15, 1994,
the scope of the License Agreement was broadened to permit USAT to use the
technology for testing for methadone, benzodiazapines, barbituates,
propoxyphene, tricyclic antidepressants and anabolic steroids.  Except as set
forth in the two preceding sentences, USAT under the License Agreement cannot
use the USN technology to test for other substances.  By an amendment dated
June 16, 1995, the term of the exclusive right under the License Agreement was
extended to terminate ten years from June 27, 1995 and USAT has a nonexclusive
right to use the technology thereafter for the balance of the patent term,
unless the License Agreement is terminated sooner because of USAT's default.
By letter dated May 15, 1995, the USN notified USAT that, because the
expiration date of the USN patent had been extended to February 23, 2010 under
the GATT/WTO treaty, the expiration date of the License Agreement was extended
to February 23, 2010.  See the section "Material Contracts--License Agreement
under this caption "Business of U.S. Drug."  U.S. Drug's line of products under
development are based on its sublicense from USAT for Drug of Abuse detection
utilizing the USN patent for flow immunosensor technology.  Because the USN
refused to grant a novation to U.S. Drug of the License Agreement as requested,
the USN looks to USAT, not U.S. Drug, for performance thereunder.  In the event
of a default under the sublicense, all rights would revert to USAT.  U.S. Drug
is developing its own proprietary "Immunoassay Chemistry" for these five drugs
which will work with the USN-developed technology.  U.S. Drug has received six
approvals from the FDA covering its Model 9000 Flow Immunoassay System and the
attendant assays for each of the five Drugs of Abuse listed above, using urine
as the test medium.  U.S. Drug, based on its review of current market
conditions, has decided to defer completion of the calibrators and the other
elements required to be completed in order to market the urine medium testing
product until it can complete the assays for a saliva medium testing product
and, as a result, has produced no revenues through December 31, 1995.  Until
FDA approval is obtained of the saliva medium product, no revenues are likely
to be produced.  U.S. Drug has commenced research using saliva as a testing
medium in connection with the flow immunosensor technology, is currently
conducting a feasibility study as to the product and, assuming a favorable
conclusion with respect to such study and subsequent success in the remainder
of the development program, currently expects to submit its five-panel
screening assay to the FDA late in 1997, but there can be no assurance that
such submission will occur by such date.  Management anticipates that U.S. Drug
will commence marketing its products six months to a year later.  There can be
no assurance as to when the FDA will give its approval and as to when marketing
will commence.
    





                                       95
<PAGE>   101
   
         U.S. Drug's screening tests are to be performed on a non-evidentiary
basis.  If a Drug of Abuse is detected in the screening test, the sample will
be forwarded to a laboratory, where an expensive confirmatory analysis will be
performed.  Usually gas chromatography/mass spectrometry ("GC/MS") is employed
for the evidentiary test.  U.S. Drug's marketing analysis has indicated a
greater market potential for a saliva sample portable testing instrument for
Drugs of Abuse by law enforcement agencies, correctional facilities, hospitals
and other medical facilities than a urine sample instrument.  However, because
of the expected limited life cycle of a saliva specimen, the use of this
product in other potential markets may be limited.  Currently, to U.S. Drug's
knowledge no competitor is currently offering a saliva sample testing product
on an "on site" basis.  However, management has been advised that one or more
companies may have such product under development and, although management has
no direct confirmation thereof, there can be no assurance that a competitor
will not begin to offer such a product in the future, whether before or after
U.S. Drug completes its research and development.  See "Business of the
Company-Competition-Drug Testing."
    

DRUG TESTING PRODUCTS

(1)      Urine Sample Testing-U.S. Drug's urine drug testing system can be
divided into two parts.  The first part is the instrument into which the sample
is placed.  The second part consists of the replaceable columns which will test
for the five Drugs of Abuse.  The columns are easily replaceable by
non-technical personnel and, depending on a number of factors, are generally
expected to have a life of 50 to 75 tests.

         Flow Immunoassay System - U.S. Drug's initial instrument system was
the Model 9000, which received marketing approval from the FDA.  See the
section "Government Regulation" under this caption "Business of U.S. Drug."
Resembling a personal computer, the Model 9000 features one button operation
which permits low cost use of the system by non-technical personnel.  The Model
9000 incorporates a U.S. Drug developed laser-excited fluorescence system which
will enhance detection of Drugs of Abuse.  The Model 9000 will provide an
analysis of Drugs of Abuse present in the urine sample, if any are so present.
All five Drugs of Abuse or any combination thereof can be selected for testing.
Testing on a urine sample by the Model 9000 is anticipated to take
approximately two minutes per drug selected, or ten minutes if all five are
selected.

         Drug Assays for the Flow Immunosensor System - U.S. Drug is designing
disposable drug assay columns to be utilized in connection with the Model 9000.
Each flow through column, approximately one inch long by one-half inch wide,
will test for





                                       96
<PAGE>   102
one drug (the "Target Drug").  The five separate columns each contain
antibodies specific for the Target Drug.

         The life of each column is estimated at between 50 to 75 tests.  This
will depend specifically on such factors as (i) the number of samples
containing the target drug; (ii) the amount of the Target Drug present, and
(iii) the specific drug targeted for testing.  The Model 9000 will inform the
operator, who does not have to be highly skilled, when and which column to
replace.

         U.S. Drug is working to develop one column containing all five Target
Drugs.  U.S. Drug believes this procedure would further reduce the cost of
using its drug screening system.  U.S. Drug expects the test to indicate if any
of the Drugs of Abuse are present within several minutes.  The full test
procedure would have to be run to determine the specific drug or the sample
sent out for confirmatory analysis.  The confirmatory analysis would be used
evidentially to determine which Drugs of Abuse were present.  See the section
"Research and Development" under this caption "Business of U.S. Drug."

   
         As indicated above, U.S. Drug intends to first complete its
development of the saliva sample testing product described below prior to
undertaking further development efforts with respect to the urine sample
testing product.  Accordingly, the urine sample testing product is not
currently marketable.

(2)      Saliva Sample Testing - Research is being conducted by U.S. Drug for
this development, using the flow immunosensor technology, of testing for Drugs
of Abuse from saliva samples, and for submission to the FDA for approval to use
saliva as a testing medium.  This research utilizes much of the development
work done for the Company's urine drug testing system.  The Company expects
that a full premarket approval, instead of the 510(k) procedure, may be
required by the FDA for both the testing system and the drug assays.  See the
section "Government Regulation" under this caption "Business of U.S. Drug."  If
the results of the current feasibility study are favorable, U.S. Drug may have
to hire ten additional scientists at a cost of approximately $1,000,000 per
year to complete the development of the saliva testing system for the Drugs of
Abuse.  Assuming such scientists are hired, the Company anticipates that the
earliest that the saliva testing system and drugs assays for all five Drugs of
Abuse will be ready for submission to the FDA is in late 1997.  There can be no
assurance that U.S. Drug will meet such timetable.  U.S. Drug may, as an
alternative to engaging in-house personnel, contract certain assignments to an
outside company to perform; however, there is no assurance that this
alternative will either be more cost effective or produce the desired results
at an earlier date.

<PAGE>   103
   
         Portable Immunosensor Analyzer - The Company anticipates manufacturing
a small portable device in conjunction with the flow immunosensor technology.
When used with the drug assays described below, the Company expects that this
unit will provide portable and flexible detection capability when used with
saliva samples.  It is expected that the assay time will be two minutes per
test.  There can be, however, no assurance that the Company will be able to
develop and market this product.  See the "Research and Development."

         Drug Assays for Portable Immunosensor Analyzer - The Company intends
to develop disposable assay cartridges for use with its portable model using
saliva samples.  After the sample has been collected, it will be transferred to
an assay cartridge containing five Target Drugs, and then placed into the
portable instrument.  The disposable cartridge will be thrown away after use.
Assay time is expected to be the same as using urine samples.  U.S. Drug plans
to continue its research and development efforts for the drug assays
concurrently with the portable unit.  There can be no assurance that the
Company will be able to develop and market the assay cartridges.  See "Research
and Development."

MANUFACTURING
    

         In manufacturing, the Company will be required in the United States to
follow current Good Manufacturing Practices ("GMP") as prescribed by the FDA.
See the section "Government Regulation" under this caption "Business of U.S.
Drug."  There can be no assurance that U.S. Drug will be able to enter into
suitable manufacturing arrangements with third parties which are in compliance
with GMP.  U.S. Drug's future dependence on third parties for the manufacture
and supply of products could have a material adverse effect on U.S. Drug's
profit margins and its ability to deliver its products on a timely and
competitive basis.

MARKETING AND DISTRIBUTION

   
         Representatives of the prior management of USAT had initial meetings
with representatives of Roche to discuss Roche's possible assistance with
respect to product development, with the intention ultimately to finalize some
marketing arrangement; however, all discussions were on a preliminary basis and
related only to assistance on assays as part of the product development.  Such
meetings did not result in an agreement being reached.  Current management has
suspended any further discussions with Roche or any similar company because (1)
until the current feasibility study is completed, it is too early in the
product development stage to discuss such development assistance, let alone
marketing assistance; (2) although confidentiality agreements can be signed
(and were executed by Roche), there are
    





                                       98
<PAGE>   104
   
risks in giving confidential data relating to a product to a competitor (Roche
is a competitor of U.S. Drug); and (3) it is preferable to avoid having to give
up future revenues if other alternatives remain open.

         Although U.S. Drug had engaged the services of a consultant to
undertake a marketing survey, because of the delays in the development of its
products due to the decision to have a test using a saliva sample, a definitive
marketing program has not been finalized or implemented.
    

GOVERNMENT REGULATION

         U.S. Drug's proposed screening and diagnostic products will be subject
to significant government regulation in the United States and other countries.
In order to conduct clinical tests, manufacture and market products for human
diagnostic use, U.S. Drug must comply with mandatory procedures and safety
standards established by the FDA and comparable foreign regulatory agencies.
Typically, such standards require that products be approved by the FDA or
comparable foreign regulatory agencies, as appropriate, as safe and effective
for their intended use prior to being marketed.

         The FDA regulates the introduction, manufacturing, labeling,
recordkeeping and advertising for all medical devices in the United States.
There are two principal methods by which FDA approval may be obtained to market
medical device products, such as the Company's proposed screening and
diagnostic test kits, in the United States.  One method is to seek FDA approval
through a pre-market notification filing under Section 510(k) ("510(k)") of the
Food, Drug and Cosmetics Act.  Applicants under the 510(k) procedure must prove
that the device for which approval is sought is "substantially equivalent" to
devices on the market prior to the Medical Device Amendments of 1976 or devices
approved thereafter pursuant to the 510(k) procedure.  In some cases, data from
clinical studies must be included in the 510(k) application.  The review period
for a 510(k) application is 90 days from the date of filing the application.

         If the 510(k) procedure is not available, then pre-market approval
("PMA") must be obtained from the FDA.  Under the PMA procedure, the applicant
must obtain an Investigational Device Exemption ("IDE") before beginning the
substantial clinical testing which is required to determine the safety,
efficacy and potential hazards of the product.  Safety and efficacy must be
established through extensive clinical studies, which are conducted after the
FDA's acceptance of an IDE application.  On completion of all of the
requirements of the IDE, and once the results are evaluated, a PMA application
is submitted to the FDA.  The review period under a PMA application is 180 days
from the date of filing, but the application is not automatically deemed





                                       99
<PAGE>   105
approved if not rejected during that period.  The FDA may grant marketing
approval, request additional data about the product's safety and efficacy or
deny the application if it determines that the product does not meet the
regulatory approval criteria.  In addition, the preparation of a PMA
application is significantly more complex and time consuming than the 510(k)
procedure and the FDA's review of a PMA is more extensive than that required
for a 510(k) application.

         No assurance can be given that any agency will grant approval for the
sale of U.S. Drug's products for routine screening and diagnostic applications
or that the length of time the approval process will require will not be
extensive.

         The cost associated with the filing of applications with the FDA and
of research and development activities to support such applications, including
clinical trials, can be significant.  There can be no assurance that the cost
of U.S. Drug's research and development activities will not exceed that which
is budgeted, nor that any of U.S. Drug's proposed products will ever obtain the
necessary FDA or foreign regulatory clearances for commercialization.

   
         Pursuant to applications filed by U.S. Drug, to date, U.S. Drug has
received approval to manufacture and market the Model 9000 and five assays -
the assay which detects the presence of cocaine (and its metabolite
benzoylecgonine), the assay which detects the presence of opiates (including
heroin, codeine and morphine) the assay which detects amphetamines, the assay
which detects phencyclidine hydrochloride (PCP) and the assay which detects
tetrahydrocannabinoids (THC, marijuana) in urine samples.  However, as
indicated herein because of the decision to complete development of a saliva
sample testing product prior to completing the development work with respect to
the urine sample testing product, no such manufacture or marketing has
commenced.  See the section "General" under this caption "Business of U.S.
Drug."
    

         In addition, regulations implementing the Clinical Laboratory
Improvement Amendments of 1988 ("CLIA"), promulgated by the United States
Department of Health and Human Services ("HHS") and the Health Care Financing
Administration on February 28, 1992, which were to become effective September
1, 1992, require that all employment drug testing, including on-site testing,
be processed by a federally approved laboratory.  On August 28, 1992, HHS
announced that the application of CLIA to workplace testing would not go into
effect on September 1, 1992 because of comments made on the final regulations.
The comments raised questions about, among other things, whether bringing
employee drug testing under CLIA might have an unintended chilling effect on
efforts to encourage drug-free workplace programs.  As reported in the January
19, 1993 Federal Register,





                                      100
<PAGE>   106
   
the final decision on the regulations will be delayed until further
investigation is completed and has not been made as of the date hereof.  U.S.
Drug believes that these regulations will not be made effective because (a) the
increased costs and burdensome procedures imposed by CLIA will significantly
reduce the volume of drug tests conducted, which is in direct conflict with the
government's long-standing war on drugs, (b) workplace testing is forensic in
nature (i.e, for the purpose of determining whether an individual is using
illegal drugs) and not for medical purposes (i.e., to make a health assessment
for diagnostic or treatment purposes) as was the original intent of CLIA and
(c) inclusion of employment drug testing may be a direct violation of the
Federal Administrative Procedures Act under Title 5 of the United States Code
and the United States Constitution.  If the regulations are not adopted,
on-site drug testing in the workplace will not be subject to CLIA.  Although
the Company has a laboratory through Biotox (see "Business of the
Company-Alcohol Testing Marketing-Drug and Alcohol Testing Services"), the U.S.
Drug management believes that the consequences of adoption of the regulations
would add to U.S. Drug's costs and, accordingly, this could have a material
adverse impact upon its business with respect to employment testing in the
private sector.
    

RESEARCH AND DEVELOPMENT

   
         During fiscal 1996, U.S. Drug spent approximately $851,000 expended on
development of the drug testing technology.  In fiscal 1995, U.S. Drug spent
approximately $886,000 expended on development of the technology of U.S. Drug.
In fiscal 1994, U.S. Drug spent approximately $728,000 expended on development
of the technology by U.S. Drug.

         In September 1995, U.S. Drug engaged the services of RELA, Inc., a
Colorado based engineering firm and a wholly-owned subsidiary of Colorado
MedTech Inc., to complete the engineering of the saliva sample test for drugs
of abuse.  Such services have been discontinued and instead U.S. Drug, with
certain assistance by subcontractors of RELA, is conducting a feasibility study
which it expects to be completed by October 1996.  If the results of the study
are favorable and the remainder of the development program is successful, U.S.
Drug anticipates submitting its five-panel screening assay to the FDA late in
1997.  There can be no assurance, however, that this schedule will be met.
U.S.  Drug estimates that it will require additional capital of $4,500,000 to
$5,000,000 in order to complete the development of its drug testing products.
The foregoing estimate does not include the estimated expenses of $2,000,000 to
$2,500,000 for manufacturing line start-up expenses relating to the chemistry
aspects of the product assuming that the development program is completed, as
to which there can be no assurance.  As part of the foregoing expenses, U.S.
Drug may have to engage additional technical
    





                                      101
<PAGE>   107
   
personnel at an estimated cost of $1,000,000 per year in order to develop the
saliva tests for Drugs of Abuse other than cocaine on a timely basis.  The U.S.
Drug management will also consider as an alternative engaging an unrelated
company to perform part of the research and development services if such
approach appears to be more cost effective.  While U.S. Drug believes such
technical personnel will be available, there can no assurance that they will be
engaged on a timely basis or as to when all tests will be made available for
FDA submission.  See the section "Government Regulation" under this caption
"Business of U.S. Drug."
    

PATENTS AND TECHNOLOGY

         U.S. Drug has rights under the following patents:

         1.  U.S. Patent No. 5,183,740," Flow Immunosensor Method and
             Apparatus," issued on February 2, 1993;

         2.  U.S. Patent No. 5,066,859, "Hematocrit and Oxygen Saturation Blood
             Analyzer," issued on November 19, 1992; and

         3.  U.S. Patent No. 5,354,654, "Lyophilized Ligand-Receptor Complexes
             for Assay and Sensors" issued on October 11, 1994.

For additional information, see the sections "Research and Development" and
"Material Contracts" under this caption "Business of U.S. Drug."

         The patent position of technology firms is highly uncertain and
involves complex legal and factual questions.  Competitors have filed
applications for, and in some instances have been issued, patents and may
obtain additional patents and other proprietary rights relating to products or
processes, such as U.S. Drug's proposed immunoassay sensor, which may be
competitive with those of U.S. Drug.  The scope and validity of these patents
are presently unknown.  U.S. Drug is not aware of any patents covering an
immunoassay sensor similar to U.S. Drug's.  Companies which have or may obtain
patents relating to products or processes competitive with those of U.S. Drug
could bring legal actions against U.S. Drug claiming damages and seeking to
enjoin it from manufacturing, licensing and marketing the affected product.  To
date, no claims have been made against U.S. Drug for infringement of any
patents.  However, marketing of U.S. Drug's products has not begun and claims,
if any, would not be asserted until market introduction of such products.  If
such a claim were to be made, its defense would be costly and U.S. Drug's
business would be adversely affected, even if U.S. Drug were to prevail.  No
assurance can be given that U.S. Drug would be able to prevail in any such
action or that any license required under any such patent would be made
available on acceptable terms.





                                      102
<PAGE>   108
         Process patents have certain disadvantages when compared with product
patents.  It is more difficult to detect and prove infringement of process
patents because it is sometimes impossible to ascertain the method by which any
product has been produced.  In addition, the value of U.S. Drug of receiving a
process patent may be reduced if products which can be derived from such
processes have been patented by others.  The patents owned by, or licensed to,
U.S. Drug include both process patents and product patents.

         U.S. Drug maintains a policy of seeking patent protection in the
United States and other countries in connection with certain elements of its
technology when it believes that such protection will benefit U.S. Drug.
Lyophilization patent applications have been filed in Canada, certain European
countries and Japan.  The patent laws of foreign countries may differ from
those of the United States as to the patentability of U.S. Drug's products and
processes and, accordingly, the degree of protection afforded by foreign
patents, if issued, may be different from protection afforded under associated
United States patents.  There can be no assurance that patents will be obtained
either in the United States or in foreign jurisdictions with respect to U.S.
Drug's inventions or that, if issued, the patents will be of substantial
protection or commercial benefit to U.S. Drug.

         Certain inventions of U.S. Drug may prove to be unpatentable or U.S.
Drug may conclude that it would be more advisable to retain a patentable
invention as a trade secret.  In either case, U.S. Drug would have to rely on
trade secrets, proprietary know how and continuing technological innovation to
develop and maintain its competitive position.  All key employees and
consultants of U.S. Drug have executed, and project sponsors and manufacturers
will be required to execute, agreements to maintain the confidentiality of U.S.
Drug's proprietary information to which they have access.  There can be no
assurance that these confidentiality agreements will be honored or will be
effective.  Manufacturers, project sponsors and consultants may be engaged in
competing research projects outside the scope of their agreements with U.S.
Drug.  There can be no assurance that such sponsors and consultants will not
develop similar or superior technology independently and to the extent that
such persons apply technical information independently developed by them to
projects undertaken by U.S. Drug, disputes may arise as to the proprietary
rights to such information.

MATERIAL CONTRACTS

(a)      License and Sublicense Agreements

         Pursuant to an amended sublicense agreement dated as of September 23,
1993, superseding the sublicense agreement dated January 2, 1993, (the
"Sublicense") by and between USAT and U.S. Drug, U.S. Drug is the sole and
exclusive sublicensee of USAT under the License Agreement.  In accordance with
the terms and provisions of the Sublicense, U.S. Drug has assumed all of USAT's
rights and undertaken all of USAT's obligations under the License Agreement.
Because the USN refused to recognize a novation to U.S. Drug of the License
Agreement as requested, the USN looks to USAT, not U.S. Drug, for performance
thereunder.  In the event of a default under the Sublicense, all rights would
revert to USAT.

         The License Agreement initially provided that the USN shall be paid a
royalty equal to six percent of the Net Selling Price (as defined in the
License Agreement) for each Royalty-Bearing Product (as defined in the License
Agreement) made, used or sold by USAT or its sublicensees in the Licensed
Territory with minimum annual royalty payments of $180,000 for 1993, $375,000
for 1994, $600,000 for 1995 and $1,000,000 for 1996 and each calendar year
thereafter throughout the term of the License Agreement.  The License Agreement
provides that the USN shall approve all sublicenses and, in accordance with
such provision, the Sublicense was approved by the USN on September 24, 1993.
The aforementioned minimum annual royalties were amended November 28, 1994 as
follows: the minimum annual royalty for 1995 was reduced to $375,000 and for
1996 it was reduced to $600,000.  In June 1995, the License Agreement with the
USN was renegotiated and amended to provide for minimum annual royalties of
$100,000 per year commencing October 1, 1995 and terminating September 30,
2005.  Additional royalties will be paid pursuant to a schedule based upon
sales of products.  By letter dated May 15, 1995, the USN notified USAT that,
because the expiration date of the USN patent had been extended to February 23,
2010 under the GATT/WTO treaty, the expiration date of the License Agreement
was extended to February 23, 2010.

(b)      CRDA

         On April 16, 1992, USAT entered into a 12-month cooperative research
agreement ("CRDA") with the Naval Research Laboratory section of the USN (the
"NRL") to further develop the licensing technology of the "Flow Immunosensor".

         Pursuant to an agreement dated as of January 1, 1993 by and between
USAT and U.S. Drug, USAT assigned to U.S. Drug all of its rights under the
CRDA.  The purpose of the CRDA is to develop the prototype instruments based on
the Flow Immunosensor Method and Apparatus Technology.  See the section
"Research and Development"





                                      104
<PAGE>   110
under this caption "Business of U.S. Drug."  Pursuant to the CRDA, each party
may retain title to any patent obtained by such party in the performance of
work under the CRDA.  The NRL has the right of first election to file a patent
application in the United States on joint inventions made in the performance of
work under the CRDA and U.S. Drug, as assignee, has the right of first election
to file a patent application on such joint inventions in all other countries.
Pursuant to an amendment to the CRDA dated May 1993, the NRL waived such right
of first election with respect to the lyophilization process for the
freeze-drying of immunoassay chemicals, provided that USAT filed an approved
patent application on such process within three months from the date of
execution of the amendment.  The approved patent application was filed on July
16, 1993 and issued as U.S. Patent No. 5,354,654 "Lyophilized Ligand-Receptor
Complexes for Assays and Sensors" on October 11, 1994.  The Patent has been
assigned to U.S. Drug by USAT.

(c)      Assignment of Agreement For Patent No. 5,066,859

         Pursuant to an assignment agreement dated January 16, 1992, Messrs.
Maurice N. Karkar and James C. Velnosky (the "Inventors") assigned to USAT all
of their rights, title and interest throughout the world in, to and under
certain improvements relating to blood analyzers and disposable syringes for
use in medical analyzers as more fully described in U.S. Patent No. 5,066,859,
U.S. Patent Application Serial No.  07/789,088 and a Patent and Cooperation
Treaty Patent Application entitled "Hematocrit and Oxygen Saturation Blood
Analyzer" (the "Licensed Inventions").  USAT paid $24,000 for such assignment
and has agreed to pay the Inventors a royalty in the amount of five cents per
disposable syringe device manufactured and sold by USAT, which amount is
indexed for inflation.  In addition, USAT also agreed to pay to the Inventors
(i) a royalty in the amount of seven percent of the net sales price of any
medical analyzer device encompassed within the scope of the Licensed Inventions
which utilize non-disposable syringe devices therein and (ii) a royalty in the
amount of five cents per syringe device or five percent of the net sales price
of such syringe device, together with an additional royalty in the amount of
seven percent of the net sales price of all medical analyzer devices, sold by
approved licensees of USAT, which amounts are also indexed for inflation.  USAT
was obligated to use its best efforts to diligently market disposable syringe
devices and medical analyzer devices.  If USAT did not begin shipment of such
products by July 16, 1993, the assignment agreement could have been immediately
terminated by the Inventors.  Additionally, USAT agreed that, after July 16,
1993 and continuing thereafter, it would manufacture and sell a minimum number
of 30,000 disposable syringe devices per month, or alternatively, pay the
Inventors the royalties due on such 30,000 disposable syringe devices per
month.  A novation of such assignment agreement has been executed such that
U.S. Drug, and





                                      105
<PAGE>   111
not USAT, is considered the Assignee (as such term is defined therein).

         Pursuant to a letter of understanding executed in August 1995, (1)
U.S. Drug agreed to provide four working type prototypes to Mr.  Karkar on or
about August 1, 1996; (2) Mr. Karkar agreed to conduct all marketing efforts;
(3) minimum royalty payments by U.S. Drug were to continue for up to one year
after the delivery to Mr. Karkar of the prototypes; and (4) net profits were to
be shared as follows: 25% by each of Messrs. Karkar and Velnosky and 50% by
U.S. Drug.

(d)      Management Agreement

         For information relating to the Management Agreement between USAT and
U.S. Drug, see "Material Contacts of USAT with U.S. Drug- Management Services
Agreement."

EMPLOYEES

   
         As of June 30, 1996, U.S. Drug employed five persons, excluding
independent contractors and the personnel employed by USAT who provide
management and administrative services to U.S. Drug.  U.S. Drug believes it has
good relationships with its employees and independent contractors.  U.S. Drug
may hire ten new scientists during the next 12 months.  See the section
"Research and Development" under this caption "Business of U.S. Drug."
    

PROPERTIES

         U.S. Drug maintains its principal executive offices, manufacturing
space and laboratory facilities in Rancho Cucamonga, California.  The premises,
which consists of approximately 10,000 square feet, are sub-leased from USAT.
U.S. Drug's operations and space are separated, and where necessary isolated,
from the operations and space of USAT.

LEGAL MATTERS

         U.S. Drug is not a party to any material litigation and is not aware
of any pending litigation that could have a material adverse effect on U.S.
Drug's business, results of operations or financial condition.


                          USAT PRINCIPAL STOCKHOLDERS

Other Compensation

         USAT currently has no pension plan in effect and has no stock option
plan, restricted stock plan, stock appreciation rights nor any other long-term
incentive plan under which grants or awards may be made in fiscal 1997 or
thereafter.  The Board is, however, considering adoption of a stock option plan
for directors, officers and key employees of the Company.
    

EMPLOYMENT AGREEMENTS

   
         USAT had entered into employment agreements (the "Employment
Agreements") with each of James C. Witham, Karen B. Laustsen and Gary S.  Wolff
providing for a three-year term commencing January 1, 1994 and terminating
December 31, 1996.  On April 18, 1996, Mr. Witham and Ms.  Laustsen resigned
their directorships and officerships, but agreed to continue to serve USAT as
employees until May 31, 1996.  Mr. Wolff resigned as Treasurer, Chief Financial
Officer, and the Chief Accounting Officer of USAT, Good Ideas and U.S. Drug and
as a director of Good Ideas and U.S. Drug on July 3, 1996.  The Employment
Agreements terminated on May 31, 1996 as to Mr. Witham and Ms. Laustsen and on
July 3, 1996 as to Mr. Wolff, except that USAT made a $25,000 severance payment
to Mr. Wolff and is continuing medical benefits for the three former executive
officers until December 31, 1996, the original expiration date of the
Employment Agreements.  Mr. Wolff is, however, continuing to assist USAT in its
efforts to sell the stock or assets of Good Ideas.

         Pursuant to his Employment Agreement, Mr. Witham was employed as the
President and Chief Executive Officer of USAT at an annual base salary of
$330,000.  Pursuant to her Employment Agreement, Ms. Laustsen was employed as
an Executive Vice President at an annual base salary of $132,000.  Pursuant to
his Employment Agreement, Mr. Wolff was employed as the Treasurer and Chief
Financial Officer at an annual base salary of $176,000 per year.  Each of such
salaries reflected a 10% increase effective July 1, 1995, which increase was
the first in 18 months.  Mr.  Witham and Ms. Laustsen were each required to
devote substantially all of his or her time to the business of USAT,
    





                                      121
<PAGE>   127
   
while Mr. Wolff was only required to devote a majority of his time.

         The Employment Agreements contained standard provisions for
participation by the executive in USAT's benefit programs, whether relating to
the USAT Common Stock, bonuses or medical, life and disability insurance or
otherwise.  Mr. Witham and Ms. Laustsen were each provided with a company car,
which have been returned to USAT.  The Employment Agreements also provided for
termination in the event of disability for six or more consecutive months and
termination "for cause" which means conviction for embezzlement, theft or other
criminal act constituting a felony or failure to comply with the terms and
conditions of the Agreement if such breach is not cured within seven days after
written notice is given to the executive by the Board of Directors.

         Michael J. Witham, who is the son of James C. Witham and who was the
Vice President of Manufacturing of USAT, had an employment agreement similar to
the Employment Agreements providing for an annual base salary of $115,500.
Effective September 26, 1995, Michael J.  Witham agreed to terminate his
employment agreement in consideration of a payment to him of $50,000 and an
assignment to him of a company car.  He resigned as an executive officer of
USAT, as a director of U.S. Drug and no longer serves the Company in any
capacity.

         Effective April 18, 1996, Robert Stutman, the President and a
principal shareholder of RSA, became the Chief Executive Officer of USAT.  Mr.
Stutman's annual base salary is $225,000.  He will receive a cash bonus of
$100,000 if the Company breaks even or is profitable in fiscal 1997 and an
additional $150,000 if the Company has net earnings of $2,000,040 in fiscal
1997.  Cash bonuses will be discretionary in subsequent years.  He will also
receive a one-time cash bonus of $50,000 upon ProActive satisfying certain
performance standards.  In the event that Mr.  Stutman is terminated without
cause (to be defined) during the first three years that he is employed by USAT,
he shall receive severance pay in an amount equal to the base salary that would
have been paid to him after the date of termination had Mr. Stutman not been
terminated and had he been employed by USAT for a period of three years.

         Effective May 13, 1996, Linda H. Masterson, a member of USAT's Board
of Directors, was employed as the President and Chief Operating Officer of
USAT.  Ms. Masterson's annual base salary is $175,000.  Ms. Masterson was
granted a warrant to purchase 600,000 shares of the USAT Common Stock.  If USAT
adopts a stock option plan, then the Common Stock purchase warrant will be
converted to a stock option subject to such plan.  In either case, the exercise
price is $3.125 per share and the option or warrant became exercisable over a
four-year period as follows:
    





                                      122
<PAGE>   128
   
50,000 shares upon commencement of the term of employment (i.e., May 13, 1996)
100,000 shares at the end of the first year, 150,000 shares at the end of the
second year, 150,000 shares at the end of the third year and 150,000 shares at
the end of the fourth year.  The expiration dates of the stock option will be
in accordance with the terms of the stock option plan and the expiration dates
of the warrant will be four years from the respective dates on which the
warrant becomes exercisable.  A discretionary cash and/or stock bonus may be
paid commencing with the fiscal year after the fiscal year in which the Company
first has positive earnings.  A bonus in the form of stock options pursuant to
an employee stock option plan or warrants, if no such plan is adopted, shall be
granted in respect of fiscal 1997 as follows:  33,000 shares if the Company
breaks even in fiscal 1997 and an additional 50,000 shares if the Company has
net earnings of $2,000,040 for fiscal 1997.  In the event that Ms. Masterson is
terminated without cause (as defined), she shall be paid severance equal to her
annual base salary.

         No employment agreements will be executed with Mr. Stutman or Ms.
Masterson, however, written agreements have been prepared evidencing the
severance provisions and are filed as exhibits to the Registration Statement.
    

DIRECTORS' COMPENSATION

   
         Prior to the change on September 26, 1995 in the composition of the
Board (see "Summary-Recent Developments"), directors of USAT who were not
employees were eligible to receive 10,000 shares of the Common Stock in the
current fiscal year, in addition to being reimbursed for their travel and other
expenses.  On each September 26, 1995, 10,000 shares of the Common Stock were
allocated to each of Glenn Bergenfield and William DiTuro, then directors, on
September 26, 1995.

         On November 16, 1995, as modified on December 11, 1995, the Board
approved the following compensation arrangements for directors who are not
employees of the Company: (1) each year the director will receive a USAT Common
Stock purchase warrant to purchase 10,000 shares of the USAT Common Stock
exercisable at the closing sales price on the date of grant (USAT Common Stock
purchase warrants were granted to five directors (i.e., Alan I. Goldman, John
C. Lawn, Peter M. Mark, Linda H. Masterson and Lee S. Rosen to purchase an
aggregate of 50,000 shares at $1.9375, the closing sales price on November 16,
1995); (2) an annual payment of $10,000 and (3) a quarterly payment of $2,500
provided that the director attends at least 75% of the meetings during the
year.  The Board also authorized an annual payment of $1,000 for a director
serving as the Chairman of a Board committee and $500 for serving as a member
of a Board committee.  The Board approved the following compensation for all
directors: the issuance of a USAT Common Stock purchase warrant to purchase
10,000 shares of
    





                                      123
<PAGE>   129
   
the USAT Common Stock at an exercise price for each share equal to the closing
sales price as reported on each anniversary date of each November 16, 1995 for
each $1.00 rise over the closing sales price of the USAT Common Stock on
November 16th of each year (which would be $1.9375 for November 16, 1995), the
rise to be calculated on the basis of the average of the closing sales prices
during the 90-day period preceding the 30th day after the date on which the
results of operations for the fiscal year are announced either through a press
release or the filing of the Annual Report on Form 10-K under Section 13 of the
Exchange Act.  Based on the fact that the results of operations for fiscal 1996
were reported in a press release dated June 14, 1996, each of the current
directors will not receive a Common Stock purchase warrant in 1996 because the
average sales price during the 90 calendar days prior to July 14, 1996 was
$2.9308 per share or less than a $1.00 rise over $1.9375 per share.
    

CERTAIN TRANSACTIONS

         On October 12, 1995, the Board of Directors appointed Michael S.
McCord, a stockholder of USAT (as of March 31, 1996, he beneficially owned
403,808 shares of the Common Stock) and a former member of the Committee, as a
consultant to USAT to serve at the discretion of the Board.  For such services
he was granted on November 16, 1995 a Common Stock purchase warrant to purchase
10,000 shares of the Common Stock at $1.9375, the closing sales price on the
date of grant.  He is also to receive an annual payment of $10,000 in quarterly
installments of $2,500 assuming he is still rendering services as a consultant.

   
         In February 1996, Lee S. Rosen, a director of USAT, received (1)
$100,000 and (2)(a) a Common Stock purchase warrant expiring November 15, 1998
to purchase 400,000 shares of the USAT Common Stock at $1.9375 per share, (b) a
Common Stock purchase warrant expiring November 15, 2000 to purchase 150,000
shares of the USAT Common Stock at $3.00 per share and (c) a Common Stock
purchase warrant to purchase 150,000 shares of the USAT Common Stock at $4.00
per share for services performed in connection with USAT's offering of
2,000,000 shares of the USAT Common Stock pursuant to Regulation D of the
Securities Act.  The latter two warrants can only be exercised as to 50,000
shares of the USAT Common Stock subject thereto in proportion to the shares
issued upon the exercise of Common Stock purchase warrants expiring December
17, 1999 to purchase 2,000,000 shares of the USAT Common Stock at $2.00 per
share issued to the purchasers in such prior placement.  During May and June
1996, Mr. Rosen was paid an additional $400,000 for services rendered to USAT
in connection with the exercise of outstanding Common Stock purchase warrants
to purchase shares of the USAT Common Stock.  The payments to Mr. Rosen have
been charged to Additional Paid-In Capital.  Mr.  Rosen also received a Common
Stock purchase warrant expiring April 17,
    





                                      124

1999 to purchase 300,000 shares of the USAT Common Stock at $3.125 per share.

                          ACQUISITION CORP. MANAGEMENT

         Alan I. Goldman, John C. Lawn and Linda H. Masterson are the current
directors of Acquisition Corp.  On June 19, 1996, USAT, as the sole stockholder
of Acquisition Corporation, elected Linda Masterson, Robert Stutman, and
Michael S. McCord as the directors of Acquisition Corp. to serve if the Merger
is consummated.  Each of the directors will serve until the next annual meeting
of the stockholders of Acquisition Corp.  Mr. Stutman was elected to serve as
the Chairman of the Board, Ms. Masterson as the President and Joseph Bradley as
the Treasurer, Acting Chief Financial Officer and Acting Chief Accounting
Officer.  Mr. Stutman and Ms. Masterson were also designated as Chief Executive
Officer and Chief Operating Officer, respectively, of Acquisition Corp.  None
of Ms. Masterson, Mr. Stutman or Mr. Bradley will receive any compensation from
Acquisition Corp. for their services.

               THE COMPANY'S MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EFFECT OF MERGER

   
         During May 1996, USAT filed the U.S. Drug Registration Statement to
register shares of the USAT Common Stock to be issued to the U.S.  Drug
Minority Stockholders upon consummation of a proposed merger of U.S. Drug with
and into a wholly-owned subsidiary of USAT.  The effects of the proposed merger
(i.e., the Merger) are discussed below.

         If the Merger is consummated, USAT will have to invest at least
$4,500,000 to $5,000,000 in the drug testing operations during the next two
years in order to complete the development of the drug testing products.  The
foregoing estimate does not reflect an additional $2,000,000 to $2,500,000
required for manufacturing line start-up expenses relating to the chemistry
aspects of the product assuming that the development program is completed, as
to which there can be no assurance.  In June 1996, USAT repaid its loan from
U.S. Drug of $282,000 and authorized a loan to U.S. Drug in the amount of
$500,000, which indebtedness will be due December 31, 1996.  Because no
revenues from sales are currently expected from the drug testing operations for
at least 20 to 30 months, assuming that Acquisition Corp., as the successor to
U.S. Drug by merger, meets the current product development schedule, as to
which there can be no assurance, the drug testing operations will operate at a
loss for at least the next two fiscal years, requiring the Company to seek to
generate revenues from the combined RSA/ProActive business and from its alcohol
testing operation, assuming that the sale of Good Ideas is effected.  Although
USAT management is optimistic about the Company achieving a significant amount
of revenues from the alcohol testing and the combined RSA/ProActive operations,
there can be no assurance that management's expectations will be achieved and
in the time frame that management contemplates.  Management believes that the
combined RSA/ProActive operations can also increase the revenues from the
alcohol testing products and, when its products are developed and marketable,
those of the drug testing subsidiary.  Although the sale of the rubber
recycling operation and the desired sale of the toy operation, as to which
there can be no assurance that the latter sale will be consummated or, if sold,
as to when and for what purchase price the sale will be effected, will
eliminate a substantial portion of the Company's operating losses, such sales
will also substantially reduce the Company's revenues (the toy and rubber
recycling operations constituted 79.9% of the Company's revenues in fiscal 1995
and 67.3% in fiscal 1996).  Accordingly, in order to meet the Company's cash
requirements, particularly those relating to its drug testing operation, the
Company must develop new sources of revenues -- as to which the combined
RSA/ProActive
    





                                      128
<PAGE>   134
   
operation is the most likely source, seek additional financing and/or secure
additional exercises of outstanding USAT Common Stock purchase warrants and
stock options.  There can be no assurance that any of these sources of cash
will produce sufficient amounts required for the Company's operations,
including U.S. Drug's, although USAT management believes, as discussed below
under "Liquidity and Capital Resources," that, as the result of the private
placement completed in February 1992, the recent and anticipated exercises of
USAT Common Stock purchase warrants and other potential sources of funds, the
Company expects to meet its cash requirements for at least the next 12 months.
There can be, of course, no assurance that management's expectations will be
realized.

         If the Merger is not effected, an infusion of equity will be necessary
for U.S. Drug to maintain its listing of the U.S. Drug Common Stock on the
Pacific Stock Exchange because U.S. Drug, based on its balance sheet as of
March 31, 1996, did not meet such Exchange's assets and stockholders' equity
maintenance requirements.  Similarly, U.S. Drug would not meet the entry
requirements of the American Stock Exchange or the NASDAQ System.  Even if the
current maintenance problem is resolved by an infusion of equity, because of
the anticipated continuing losses, U.S. Drug will probably have the same
compliance problem for at least 20 to 30 months (i.e., the necessity to infuse
capital to offset operational losses).  Any delisting from the Pacific Stock
Exchange and inability to list on another exchange or the NASDAQ System will
adversely affect U.S. Drug's ability to raise additional equity financing.  In
such event, the burden to seek financing for the drug testing operation would
fall solely on USAT, which owns 67.0% of U.S. Drug and holds the license to the
USN technology.

EFFECT OF GOOD IDEAS MERGER

         During April 1996, USAT filed the Good Ideas Registration Statement to
register shares of the USAT Common Stock to be issued to the minority
stockholders of Good Ideas upon consummation of a proposed merger of a
wholly-owned subsidiary of USAT with and into Good Ideas.  The effects of the
proposed merger (i.e., the Good Ideas Merger) are discussed below.

         Management believes that, during the past three years, manufacturers
in the toy industry have faced the problem that distributors or retailers have
been requesting that the manufacturers maintain the inventory, thereby
increasing manufacturers' expenses, and have been minimizing the number of
vendors which sell to them, which has the effect of squeezing out the smaller
companies like Good Ideas with their limited product lines.  Because of these
problems which management believe are characteristic of the toy industry
generally and Good Ideas' declining sales and increasing losses, the USAT Board
of
    





                                      129
<PAGE>   135
   
Directors concluded on February 26, 1996 that Good Ideas was not likely to
reverse the trend of increasing losses during the next 12 months.  The Board
believed that, whether or not the Merger was consummated, the only way to
improve operational results was to secure new toy products, whether through
licensing arrangements or otherwise; however, this type of program, even if
successful, as to which there can be no assurance, would require substantial
cash investments, which is contrary to the Board's conclusion that the
Company's best opportunity at maximizing revenues and securing profitability
was by concentrating on its alcohol and drug testing and human resource
provider operations as its core businesses.  Accordingly, on February 26, 1996,
the USAT Board authorized seeking a purchaser for Good Ideas.  In addition, the
USAT Board suspended management fees to USAT retroactive to January 1, 1996.
The Board, believes that, pending receipt of an acceptable offer, as to which
there can be no assurance, Good Ideas' cash resources and expected cash flow
from operations, coupled with its cost reduction actions (such as not renewing
the lease for office and reducing its warehouse facilities), will be sufficient
to meet Good Ideas' cash requirements for the next 12 months if such time is
required to sell or liquidate.  However, there can be no assurance that
additional funds may not be required.  The USAT Board believes that liquidation
of Good Ideas by no later than December 31, 1996 would be preferable than
investing at that time substantial additional funds in Good Ideas, other than
repaying USAT's indebtedness to Good Ideas due December 31, 1996.  The Good
Ideas Merger would terminate USAT's obligation to make such repayment.

         If the Good Ideas Merger is not consummated, Good Ideas and USAT will
continue to be publicly-owned companies and Good Ideas will continue to be a
majority-owned subsidiary of USAT.  However, USAT intends to seek a purchaser
for Good Ideas, and, if no acceptable offer is received, to liquidate Good
Ideas on or before December 31, 1996.
    


LIQUIDITY AND CAPITAL RESOURCES

   
         Although the Company has a history of operating losses through March
31, 1996, management believes that the Company will have the cash resources
available to meet all of its operating requirements for the ensuing 12 months.
Management bases its belief on the following:

Discontinued Businesses.  Good Ideas and USRR have produced significant
operating losses over the last several years.  Both operations were treated as
discontinued operations in the financial statements for fiscal 1996.  USRR was
sold April 30, 1996.  Good Ideas' operations have been substantially suspended
and the Company is seeking a buyer for its assets.  If no
    





                                      130
<PAGE>   136
   
satisfactory offers are received, the operation will be liquidated prior to
December 31, 1996.

Nonrecurring Losses.  Fiscal 1996 included $1,137,914 in losses from the
settlement of litigation.  Management is not aware of any litigation or claims
which would cause this type of loss to recur in fiscal 1997, although there can
be no assurance that such claims will not arise.

Operational Sources.  Management believes that cash flow from operations will
be increased in fiscal 1997 through the addition of the RSA revenues and by
developing the ProActive human resource business, neither of which were
significant contributors in fiscal 1996.  Management also believes that
increased emphasis can be made on selling its Mobile Alcohol Collection System
("MACS") and Alco-Breath Tubes ("ABT") for use in industrial companies and
thereby increase the revenues in the alcohol testing operation.  By unifying
its sales force to sell both the RSA/ProActive "product" and these alcohol
testing products and changing the marketing emphasis, management believes that
increased revenues can be developed in fiscal 1997.  If the feasibility study
as to saliva based testing product currently being conducted by U.S. Drug
indicates further development is desirable, the Company can seek to have a
major pharmaceutical or other company help in the development program, which
would reduce current expenditures, but would also reduce future revenues to the
extent marketing rights are demanded by such "development partner."  To the
extent that the feasibility study indicates insurmountable problems with
respect to further development, then the anticipated further research and
development expenses can be avoided.  There can be no assurance that the
Company's operational programs will produce an increased cash flow from
operations or, if it does, when such result will be achieved.

        Management will also continue to emphasize the cost reduction programs
previously instituted.

Equity Sources.  From December 1995 to February 1996, USAT completed a private
placement of USAT Common Stock pursuant to Regulation D under the Securities
Act in which it realized gross proceeds of $3,750,000.  Because of USAT's past
history of successfully raising funds privately, management believes that this
source can be "tapped" in the future if required; however, management would
prefer not to use this method of financing because of the substantial dilution
to current stockholders which it causes and because, absent a stockholder
authorization of additional shares, the number of unreserved shares of the USAT
Common Stock is currently limited. There can be, of course, no assurance that
USAT will be able to consummate any future financings on a timely and favorable
basis in the amount necessary to meet the Company's cash requirements should
any such financing be necessary.  USAT completed a private placement
    





                                      131
<PAGE>   137
pursuant to Regulation D under the Securities Act in February 1996 in which it
realized gross proceeds of $3,750,000.  There can be, of course, no assurance
that the Company will be able to consummate any future financings on a timely
and favorable basis in the amount necessary to meet the Company's cash
requirements should any such financing be required.

   
Exercise of Warrants and Options.  Between April 1, 1996 and June 14, 1996,
warrants and options were exercised to purchase  2,353,449 shares of the USAT
Common Stock generating $4,242,000 in cash.  Outstanding unexercised USAT
Common Stock purchase warrants as of June 14, 1996 could generate approximately
$15,348,000 of new capital to the Company.  The expiration dates for many USAT
Common Stock purchase warrants, previously extended for one year in August
1994, were extended for an additional year on June 26, 1995 and, accordingly,
expire on various dates from September 1996 through December 2001.   However,
USAT will have to update or file registration statements under the Securities
Act to make these exercises more attractive to the holders.  Outstanding stock
options granted to officers and directors of USAT in August 1994, at an
exercise price of $2.375, could generate proceeds of approximately $1,040,000
if exercised.  These stock options expire on the later of (1) 30 days after the
effective date of a registration statement relating to the underlying shares or
(2) various dates, the last of which is October 1, 1996.  There can be, of
course, no assurance that any of the remaining warrants or options will be
exercised.

         In the event that the Company is unable to generate sufficient cash
flow from operations or from sources other than those described above (which
event, in management's opinion, is not likely to occur based upon past
experience; however, there is no assurance that management will be successful
in any future financing efforts), then the Company may have to provide for
additional reductions in operating costs, thereby not only resulting in less
cash from operations currently, but also delaying future revenue growth.  In
such event the market price of the USAT Common Stock is likely to drop, not
only discouraging the future exercises of the USAT Common Stock purchase
warrants and the stock options and possibly discouraging potential new
investors, but also increasing the risk that a current investor in USAT may
lose the value of his, her or its investment.

         Because USAT offers its alcohol testing products, and U.S. Drug will
offer, when the research and development program is successfully consummated,
as to which there can be no assurance, its drug testing products, in the
substance abuse industry which is noted for its scientific developments and
rapidly changing technology, each faces the risk that new or modified products
of competitors may make USAT's or U.S. Drug's products not competitive, either
from an obsolescence or a pricing point of view.  In addition, these
developments may require USAT and U.S.
    





                                      132
<PAGE>   138
Drug to expend substantial funds on research and development to remain
competitive, possibly at times when such funds may not be available.

CHANGES IN FINANCIAL CONDITION

   
         During  fiscal 1996, the Company's investments in trading securities
were sold and the Company realized proceeds of $3,610,000.  The REMIC bonds
were sold for $3,286,000 and a brokerage loan payable in the amount of
$2,570,000 was repaid.  In addition, the Company sold its 288,400 share
investment in the common stock of Marquest Medical Products, Inc. ("Marquest"),
realizing proceeds of $324,000.  The sales of these investments resulted in a
net gain of $302,000 over their carrying value on the March 31, 1995 balance
sheet.  The Company realized a loss on sale of marketable securities in fiscal
1996 of $1,889,000.  Management will make no further investments in any high
risk trading securities.

         The Company's investment policy on a prospective basis, assuming the
availability of funds not required for immediate use in the operations of the
business, will require such funds to be invested in certificates of deposit,
money market accounts, government securities and high quality commercial paper
where the principal will be substantially protected from market fluctuations.
    

OPERATING CASH FLOWS

   
         Cash used for operations was $8,711,000 for fiscal 1996.  The net loss
for the period was $10,461,000 and the difference between the net loss and the
net cash used by operating activities was $1,750,000.  Components of this
difference included:

INVESTING CASH FLOWS

   
         Cash provided from investing activities was $3,428,000 for fiscal
1996.  $3,610,000 was generated from the sales of trading securities as
described above and $220,000 was used for the purchase of property and
equipment.  Other net sources of funds amounted to $38,000.
    

FINANCING CASH FLOWS

   
         Cash provided from financing activities was $4,937,000 during the
fiscal 1996. The Company provided cash from the sale of securities in two
private placements in the aggregate gross amount of $6,788,000, from the
exercise of warrants in the amount of $167,000 and from demand loans, secured
by U.S. Drug's REMIC bonds, in the amount of $1,000,000.  Cash from the sale of
the REMIC bonds included as an investing activity was used to pay off brokerage
loans in the amount of $2,570,000.  Expenses of raising the $6,955,000 from the
placements and warrants were $363,000.  Net payments of long term debt and
payment of dividends on the Preferred "A" Stock used cash of $85,000.
    

         Cash resources will be more than adequate, in management's opinion, to
meet the Company's commitments which include lease obligations, royalty
obligations and development of products for at least the next 12 months.  There
are currently no unfunded commitments for capital expenditures.

RESULTS OF OPERATIONS

   
Fiscal 1996 vs. Fiscal 1995

         Revenues from continuing operations for fiscal 1996 were $1,166,000, a
decrease of $529,000 or 31.2% from revenues of $1,695,000 reported for fiscal
1995.  Revenues from the sale of alcohol breath analyzing equipment decreased
by $750,000, which decrease was attributable to an unusually high volume of
alcohol breath analyzing machines sold in the third quarter of the prior year
and a reduction in sales effort as the sales force was reassigned to the
ProActive startup.  Sales of the Biotox division decreased $227,000, reflecting
the end of a contract performing methadone tests.  These decreases were offset
by an increase in cost per test revenue from the alcohol breath analyzing
equipment of $185,000, miscellaneous sales of supplies of $42,000 and revenues
of $203,000 from Alconet, which was acquired March 31, 1995, and the human
resource provider business which, while still in a start up mode, produced
revenues of $18,000.

         Cost of sales for the fiscal 1996 on a continuing operations was
100.4% of revenues as compared to 82.4% of revenues for fiscal 1995 as a result
of lower sales volumes, increased labor
    





                                      134
<PAGE>   140
   
and supply costs relating to the cost per test business and an inventory
write-off of $193,000 during fiscal 1996.

         Selling, general and administrative expenses were $5,721,000 for
fiscal 1996, representing an increase of $437,000 or 8.3% from the $5,284,000
of such expenses incurred for the comparable period of the prior year.  The
expenses for fiscal 1996 included $397,000 of expenses incurred by a newly
acquired subsidiary, Alconet,  not included in the comparable numbers for the
prior year.

         Research and development expenses were $1,006,000 for fiscal 1996,
representing a decrease of $243,000 or 19.5% from the expenses in the prior
year.  Research and development expenses in connection with USAT's alcohol
testing machine decreased by $215,000 during fiscal 1996 from such expenses in
the prior year, which decrease was attributable to the fact that the machines
were placed in service in the fourth quarter of the prior year.  U.S. Drug's
research and development expenses decreased $35,000 as compared with such
expenses in the prior year.

         Loss from the settlement of litigation for fiscal 1996 included
nonrecurring legal and other expenses in the amount of $888,000 which were
incurred by USAT in connection with its settlement with the Committee of the
consent solicitation litigation.  Additionally, a non- recurring settlement of
$250,000 was paid to two former owners of Alconet, Inc. relating to a dispute
over the terms of their employment contracts.

         Depreciation and amortization was $1,018,000 for fiscal 1996,
representing an increase of $322,000 or 46.3% over depreciation and
amortization in fiscal 1995, which increase was attributable primarily to
depreciation on USAT's alcohol testing machines placed in testing sites in
connection with the cost per test agreements with major laboratories.  The
majority of these machines were placed in service in the fourth quarter of
fiscal 1995.  These machines represented an increase in depreciation expense of
$514,000 for fiscal 1996 as compared to the expense in the prior year based on
a full year's depreciation in fiscal 1996.

         The Company's operating loss of $9,006,000 for fiscal 1996 increased
by $2,029,000 over its operating loss of $6,977,000 for the prior year.  The
increased operating loss can be attributed to: the lower level of revenues
generated from the alcohol testing business attributable to an unusually high
volume of alcohol breath analyzing machines sold in the third quarter of the
prior year; negative gross margins for fiscal 1996 resulting from higher labor
and supply costs necessary to support the start up of the cost per test
business; increased selling, general and administrative expenses and
nonrecurring losses from settlement of litigation in the amount of $1,138,000,
operating losses of
    





                                      135
<PAGE>   141
   
$576,000 incurred by Alconet, a newly acquired subsidiary not included in the
prior year numbers; and increased depreciation cost relating to the cost per
test business.

         Other income, net of other expenses, for fiscal 1996 was  $409,000 as
compared to an expense of $499,000 reported for fiscal 1995.  The trading
securities sold by the Company in fiscal 1996 generated a profit of $302,000
over their carrying value in the March 1995 balance sheet.  During fiscal 1995,
these securities generated a loss of $155,000 and an unrealized loss of
$598,000.  Interest income decreased by $134,000 for fiscal 1996 as compared to
the interest income in the prior year.

         Management is of the opinion that it is too speculative to project at
this time when the Company will turn profitable because of the Company's
history of operational losses, the delay in  completing and then marketing its
urine sample drug testing product in order to wait until a saliva sample drug
testing product is available, the fact that its human resource provider program
is in its early marketing stages and the discontinued operations of the toy
subsidiary.
    


U.S. DRUG TESTING, INC. (SUBSTANCE ABUSE TESTING)

   
         During fiscal 1996, U.S. Drug continued as a development stage
enterprise with no revenues.  Selling, general and administrative expenses were
$417,000 in fiscal 1996 as compared with $850,000 in fiscal 1995 or a decrease
of $433,000, resulting primarily from a $325,000 reduction in the royalty
payments on the USAT license with the USN from $375,000 in  fiscal 1995 to
$50,000 in fiscal 1996.  Other selling, general and administrative expenses for
fiscal 1996 were comprised of royalty expenses of $62,000, rent, utilities and
telephone charges of $97,000, insurance expenses of $35,000, marketing research
expenses of $44,000, legal and auditing services of $33,000, directors' fees of
$10,000, travel expenses of $24,000 and other expenses of $112,000.  Research
and development expenditures totaled $851,000 in fiscal 1996 as compared with
$886,000 in fiscal 1995.  The 1996 expenditures consisted of payroll and fringe
benefits of $593,000, outside consulting services of $184,000 and other costs
of $74,000.  Depreciation expense decreased $19,000 from $163,000 in fiscal
1995 to $144,000 in fiscal 1996 as some assets became fully depreciated during
the year.  Management fees paid to USAT were $420,000 in both fiscal 1996 and
fiscal 1995.  For a description of the services rendered under the management
agreement relating to these fees, see the section "Subsidiaries-U.S. Drug
Testing, Inc." in Item 1 to this Report.  Interest expenses on brokerage loans
were $72,000 during fiscal 1996 as compared with $42,000 during fiscal 1995 or
an increase of $30,000 resulting from increased borrowings during fiscal 1996.
Other income (expense) resulted in net income of
    





                                      136
<PAGE>   142
   
$263,000 in fiscal 1996 as compared with net income of $31,000 in the prior
year or an increase of $232,000.  Fiscal 1996 other income (expense) is
comprised of a gain of $76,000 on the sale of REMIC bonds over their earnings
value at March 31, 1995, interest income primarily relating to the REMIC bonds
of $105,000 and interest income on loans to USAT of $82,000.  In fiscal 1995
other income (expense) was comprised of interest income, primarily on the REMIC
bond of $245,000, interest income from USAT of $20,000 and an unrealized loss
on the market value of the REMIC bonds caused by generally higher interest
rates.

         Since inception U.S. Drug has spent $2,586,000 on research and
development and $1,868,000 on selling, general and administrative expenses.
USAT had spent $678,000 on research and development and $485,000 on selling,
general and administrative expenses for the period from January 24, 1992
through December 31, 1992, when the technology was sublicensed to U.S. Drug.

         As of March 31, 1996, U.S. Drug did not anticipate generating revenues
from product sales during fiscal 1997 and, accordingly, anticipated that
operating losses would continue for at least a 12 to 24-month period.  USAT
will need to provide the funding necessary to complete the development of the
U.S. Drug products and bring them to market.

DISCONTINUED OPERATIONS
    

GOOD IDEAS ENTERPRISES, INC. (TOY)

   
         Net sales for fiscal 1996 were $1,508,000, a decrease of  $3,098,000
or 67.3% from the net sales in the prior year.  Of this decrease, $1,994,000 or
64.4% was attributable to Toys R Us, the major customer of Good Ideas, not
placing orders for Good Ideas' toy products.  The customer attributed its
reduction in orders to its large inventories and declining sales and customer
traffic.  Management believes that other manufacturers in the toy industry are
currently facing these same problems - their distributors or retailers to which
they sell have large inventories of products and declining sales and customer
traffic.  In addition, management believes that many retailers are minimizing
their number of vendors and reducing the number of items carried in inventory
which has the result of squeezing out the smaller companies with their limited
product lines.

         Net sales from Good Ideas' wooden construction toy category for the
fiscal 1996 were $967,000, a decrease of $1,874,000 or 66.0% from the net sales
in the comparable period in fiscal 1995.  Net sales from Good Ideas' equestrian
line of toys, consisting of horses, saddles and accessories, for fiscal 1996
were $531,000, representing a decrease of $682,000 or 56.2% from those in the
prior year.  Net sales of Good Ideas' other product lines for fiscal 1996 were
$10,000, a decrease of $542,000 or 98.2% from
    





                                      137
<PAGE>   143
   
the prior year.  The decrease was attributable to the discontinuance of Good
Ideas' line of corrugated cardboard construction toys because of significant
increases in the cost of materials.

         Gross profit for fiscal 1996 was $163,000 or 10.8% of net sales as
compared with $1,324,000 or 28.7% of net sales for the prior year.  The
decrease in gross profit as a percentage of net sales was primarily due to a
writeoff of inventory in the amount of $192,000,

         Selling, general and administrative expenses for fiscal 1996 decreased
to $1,279,000 from $1,924,000 for the comparable period in fiscal 1995, which
decrease was attributable to reductions in payroll and related costs during
fiscal 1996.

         Management fees paid to USAT were $225,000 for fiscal 1996,
representing a decrease of $80,000 from the $305,000 of fees paid for fiscal
1995.  The decrease resulted from USAT s suspension of the management fee
retroactive to January 1, 1996.

         Good Ideas recognized interest income of $158,000 from its loans to
related parties during fiscal 1996, as compared with $68,000 in the prior year
due to increased loan balances.  Good Ideas also recognized interest income
from money market investments of $3,500 and $44,000 during fiscal 1996 and
fiscal 1995, respectively.

         The net loss for Good Ideas was $1,566,000 for fiscal 1996,
representing an increase of $768,000 from the net loss of $798,000 reported for
fiscal 1995.  The increase in the net loss was due to the decreases in sales
and gross profit offset by the decreases in selling, general and administrative
expenses and management fees, all as described in the preceding paragraphs.
The net loss for the current year was also increased by the writedown of assets
in the amount of $258,000 and the projected costs through sale or liquidation
in the amount of $110,000.

         Unless Good Ideas were to add new products to its line, as to which
there can be no assurance, and there were a stronger demand for toy products in
the industry generally, management does not believe that a turnaround in Good
Ideas' operations would occur during the next 12 months, if not at a later
date.  Although management of Good Ideas had in the past  considered plans to
expand the product line, it was reluctant to implement these plans absent a
change in the industry conditions described above.  On February 26, 1996, the
USAT Board determined to sell or liquidate Good Ideas, a conclusion concurred
with by the Good Ideas Board.  As a result of the above decision, the assets of
Good Ideas are included in the consolidated balance sheet at management's
estimate of liquidation value and the results of
    





                                      138

operations of Good Ideas are presented on a discontinued basis.  See "The
Merger and Related Matters-Sale of Good Ideas."
    

U.S. RUBBER RECYCLING, INC. (RECYCLED RUBBER PRODUCTS)

   
         Net sales of USRR for fiscal 1996 were $892,000, a decrease of
$1,244,000 or 58.2% as compared with sales of $2,136,000 in the prior year.
This decrease was attributable to the continuing effects of the cancellation of
an agreement with a distributor (Matworks, Inc.) by USRR in October 1994
because of significant breaches of the contract by the distributor relating to
its use of competitors' flooring products in violation of a contractual
requirement to use only USRR's products.  USAT does not intend to institute any
legal action against the distributor because USRR does not want to incur the
protracted legal expenses involved in litigation.

         Gross margin for fiscal 1996 was $419,000 or 47.0% of net sales, up
from a gross margin of 41.8% of net sales for fiscal 1995.  The increase in
gross margin was attributable to an increase in the selling price of USRR's
product to its customers.  This offset an inventory write off of floor tiles
which became non-repairable during the six months ended September 30, 1995.
Floor tiles not meeting quality control standards are segregated in the
inventory for future repairs to correct the flaws and those not repairable are
discarded.  During fiscal 1995, USRR worked a double shift to meet the
production demand created by the agreement with the distributor.  Inexperienced
labor resulted in an increase in tiles not initially suitable for shipments.

         Selling, general and administrative expenses were $605,000 for fiscal
1996, representing a decrease of $214,000 from such expenses in fiscal 1995.
Of this amount, $162,000 represented a decrease in commissions and freight
related to the decline in sales revenue.

         Management fees paid to USAT were $89,000 for fiscal 1996,
representing a decrease of $124,000 from such fees in the prior year.

         Depreciation expense was $99,000 for fiscal 1996, representing an
increase of $40,000 over such expense in the comparable prior year, which
increase was attributable to the commencement of depreciation on additional
manufacturing equipment built in contemplation of potential expansion.

         Interest expense was $123,000 for fiscal 1996 as compared with a
$112,000 expense in the comparable period in 1995 as a result of borrowings
from affiliates.

         The operating loss of $492,000 for fiscal 1996 represented a decrease
of approximately $131,000 from an operating loss of
    





                                      139
<PAGE>   145
   
$623,000 for fiscal 1995.  The decrease was primarily attributable to the
increased percentage of gross margin and the decrease in selling, general and
administrative expenses incurred during fiscal 1996.

         As indicated elsewhere in this Consent Solicitation
Statement/Prospectus (see the section "Effect of Merger" under this caption
"The Company's Management's Discussion and Analysis of Financial Condition and
Results of Operations"), the USAT Board, on February 26, 1996, concluded that
the Company should concentrate on alcohol and drug testing and ProActive's
human resource provider operations as its core businesses and, accordingly,
authorized seeking a purchaser for USRR.  A sale of substantially all of the
assets of USRR was consummated on April 30, 1996.  The net loss for fiscal 1996
included a $88,000 loss on disposal of USRR's assets.
    

FISCAL 1995 VS. FISCAL 1994

   
         Revenues from continuing operations for fiscal 1995 were $1,695,000,
an increase of $1,252,000 or 282.6% over the revenues of $443,000 reported for
fiscal 1994.  This sales increase was attributable to sales of USAT's Alco
Analyzer 2100.

         Cost of sales for fiscal 1995 was 82.4% of revenues as compared to
88.1% of revenues for the prior year.  This increase was attributable to the
higher than projected costs involved in building the initial alcohol testing
machines that were sold in fiscal 1995.

         Selling, general and administrative expenses were $5,284,000 for
fiscal 1995, representing an increase of $1,524,000 over the $3,760,000 in such
expenses reported for fiscal 1994.  The Company incurred $1,230,000 of
development marketing and training costs in connection with the alcohol testing
machine during fiscal 1995.

         Research and development expenses were $1,249,000 for fiscal 1995,
representing an increase of $301,000 over the expenses reported for fiscal
1994.  Of the total expenditures in fiscal 1995, $886,000 represented research
and development by U.S. Drug in connection with technology licensed to USAT
from the USN for drugs of abuse, representing an increase of $158,000 over the
fiscal 1994 expenditures.  The Company incurred research and development
expenditures of $363,000 during fiscal 1995 in connection with the development
of its alcohol testing machine, representing an increase of $143,000 over the
expenditures for fiscal 1994.

         Depreciation and amortization was $695,000 for fiscal 1995,
representing an increase of $314,000 over the $381,000 in
    





                                      140
<PAGE>   146
   
depreciation and amortization reported for fiscal 1994, primarily attributable
to depreciation of the alcohol testing machines.
    

         Losses from settlement of class action and other litigation were
$4,650,000 for fiscal 1994.  The Company incurred no similar costs during
fiscal 1995.

   
         Operating losses of $6,977,000 for fiscal 1995 decreased by $2,710,000
from the losses of $9,687,000 reported for fiscal 1994, primarily attributable
to the litigation losses of $4,650,000 incurred for fiscal 1994.  The
contributions to operating losses by subsidiaries, representing segments other
than alcohol testing, are detailed below.

         Other income (expense) for fiscal 1995 and 1994 included charges for
unrealized losses on marketable securities of $598,000 and $388,000,
respectively.  A primary cause of these charges was the decline in the market
value of the Company's investments in REMIC bonds issued by the Federal Home
Loan Mortgage Corporation and the Federal National Mortgage Association.  The
Company originally invested in the REMIC bonds on the advice of a registered
broker-dealer which recommended these bonds as an investment with high interest
rates and low market risk.  The Company, through inexperience in dealing with
this type of investment, did not enter into any hedging transactions to
mitigate these losses and held the bonds in anticipation of increases in their
market value.  Upon such increases in market value, the Company sold the bonds,
partially recovering its  previously recorded unrealized losses.  Since
December 1993, no additional investments of this type have been made and none
are contemplated in the future.  Interest income was $250,000 for fiscal 1995,
representing an increase of $156,000 over the $94,000 in interest income
reported for fiscal 1994, which increase was attributable to an increase in
interest earned for fiscal 1995 by U.S. Drug of $159,000 by virtue of having
the excess proceeds from its initial public offerings, completed during fiscal
1994, invested for a full twelve months.
    

U.S. DRUG TESTING, INC. (SUBSTANCE ABUSE TESTING)

   
         During fiscal 1995, U.S. Drug, a development stage enterprise with no
revenues, spent $886,000 on research and development as compared with $728,000
in such expenses in the prior year.  During fiscal 1995, U.S. Drug also spent
$850,000 on selling, general and administrative expenses as compared with
$604,000 in the prior year.  USAT spent $678,000 on research and development
and $485,000 on selling, general administrative expenses for the period from
January 24, 1992 through December 31, 1992, when the technology was transferred
to U.S. Drug.

         U.S. Drug paid management fees to USAT of $420,000 in both fiscal 1995
and fiscal 1994.  During fiscal 1995, the loss from
    





                                      141
<PAGE>   147
   
operations of $2,363,000 also reflected interest of $44,000 on brokerage loans
and depreciation of $163,000.  During fiscal 1994, the loss from operations of
$1,876,000 also reflected interest and depreciation of $124,000.

         U.S. Drug's operating loss was $2,363,000 in fiscal 1995 as compared
to operating losses of $1,876,000 in fiscal 1994.  These operating losses were
attributable to the fact that U.S. Drug was expending funds for research and
development and selling, general and administrative expenses as indicated in
the second preceding paragraph, as well as incurring a management fee to USAT
and the other expenses as described in the preceding paragraph, while not
realizing any revenues.

DISCONTINUED OPERATIONS
    

GOOD IDEAS ENTERPRISES, INC. (TOY)

   
         Net sales for fiscal 1995 were $4,606,000, a decrease of $938,000 or
16.9% from the net sales in the prior year.  Net sales from Good Ideas' wooden
construction toy category for fiscal 1995 were $2,841,000, a decrease of
$733,000 or 20.5% from the net sales in the fiscal year ended March 31, 1994
("fiscal 1994"), which decrease was attributable to a decline in this category
sales by Toys R Us, Good Ideas' major customer, resulting in a reduction of
orders placed by such customer.  The customer attributed its reduction in
orders to its large inventories and declining sales and customer traffic.
Management believes that other manufacturers in the toy industry are currently
facing these same problems - their distributors or retailers to which they sell
have large inventories of products and declining sales and customer traffic.
In addition, net sales from Good Ideas' equestrian line of toys for fiscal 1995
were $1,123,000, representing an increase of $198,000, or 19.5%, over the sales
in fiscal 1994.  This increase was attributable to the sales of a new product
introduced into the equestrian line at the end of fiscal 1994.  Net sales of
Good Ideas' corrugated cardboard construction toy category for fiscal 1995 were
$344,000, a decrease of $69,000 or 16.7% from the net sales for fiscal 1994.
Price increases in the cost of the corrugated cardboard resulted in price
increases to Good Ideas' customers, with a resulting decline in sales.  This
category was ultimately removed from the product line at the beginning of
fiscal 1996.  The remaining decrease in net sales for fiscal 1995 as compared
to the net sales in fiscal 1994 was the result of sales of other products which
had been introduced into the line on an unsuccessful basis and sold at
discounted prices in order to avoid carryover of slow-moving inventory.
    

         Gross profit for fiscal 1995 was $1,324,000 or 28.7% of net sales as
compared to $1,487,000 or 26.8% of net sales for fiscal 1994.  The increase in
gross profit as a percentage of net sales





                                      142
<PAGE>   148
was primarily due to Good Ideas' effort to increase its gross margins on
product sold by either raising selling prices or adjusting the quantity of
parts in its playsets.

   
         Selling, general and administrative expenses for fiscal 1995 increased
to $1,924,000 or 41.8% of net sales from $1,488,000 or 26.8% of net sales for
fiscal 1994.  This increase was the result of two factors. First, the fixed
overhead was spread over a decreased sales volume.  Second, Good Ideas
experienced increased legal and other expenses of approximately $127,000,
increased payroll costs of $86,000 resulting from additional employees hired
and increased travel and promotion expenses in the amount of $97,000 resulting
from Good Ideas' efforts to expand its business base.

         Pursuant to the Management Services Agreement, USAT's fees for
management and administrative services provided to Good Ideas during fiscal
1995 were $305,000, representing a decrease of $120,000 from the fees in fiscal
1994.  This decrease was the result of two factors.  First, during fiscal 1994,
USAT's fees were computed at ten percent of net sales through September 30,
1993, while such fees were computed based on a flat monthly charge of $25,000
on the first $5,000,000 of net sales during fiscal 1995.  Second, the decline
in net sales volume for fiscal 1995 kept the management fee from becoming
subject to a five percent surcharge on all sales over $5,000,000.

         During fiscal 1995, Good Ideas repaid its debt to USAT and made loans
to USAT in the amount of $1,196,000 and to USRR in the amount of $1,027,000.
During fiscal 1995, Good Ideas recognized interest income of $68,000 from these
loans to related parties and also received interest income of $42,000 from
money market investments.  Good Ideas incurred minimal interest expense during
fiscal 1995.

         Good Ideas had a loss from operations of $905,000 in fiscal 1995 as
compared to  a loss from operations of $426,000 in fiscal 1994, an increase of
$479,000 or 112.4%.  The increase in operating loss was due to the decrease in
sales and the increase in selling, general and administrative expenses, offset
by the decrease in the management fee, as described in the preceding
paragraphs.
    


U.S. RUBBER RECYCLING, INC. (RECYCLED RUBBER PRODUCTS)

         USRR's net sales of $2,136,000 for fiscal 1995 increased by $941,000
or 78.7% over the net sales of $1,195,000 in fiscal 1994, which increase was
attributable to a new agreement with a distributor for product placed in a
major retailer.  The agreement was canceled by USRR in October 1994 because of
significant breaches of the contract by the distributor relating





                                      143
<PAGE>   149
to its use of competitors' flooring products in violation of a contractual
requirement to use only USRR's products.  USRR does not intend to institute any
legal action against the distributor because USRR does not want to incur the
protracted legal expenses involved in litigation.

   
         Gross margin for fiscal 1995 was $581,000 or 27.2% of net sales, a
decrease from $460,000 or 38.5% of net sales for fiscal 1994.  The decrease in
gross margin was attributable to manufacturing inefficiencies, resulting from
running a double shift which was necessitated by the increase in product demand
arising from the agreement with the distributor (Matworks, Inc.).  As a result
of the double shift, an increase in the number of tires was required to supply
the second shift, resulting in additional costs to USRR to purchase tires to
maintain an adequate inventory, to remove waste from the increased volume of
tires processed and an increase in the number of irregular tiles produced
causing additional repair labor cost because of the training required for the
new labor force to staff the second shift.
    

         Selling, general and administrative expenses were $819,000 for fiscal
1995, representing an increase of $151,000 over the $668,000 of expenses for
fiscal 1994.  Of this amount, $131,000 represented additional payroll and
consulting fees resulting from an expansion of the business.

         Management fees paid to USAT were $213,000 for fiscal 1995,
representing an increase of $94,000 over the $119,000 reported for fiscal 1994,
which increase was related to the increase in sales.

         Depreciation expense was $59,000 for fiscal 1995, representing an
increase of $18,000 over such expense in the fiscal 1994, which increase was
attributable to the commencement of depreciation on additional manufacturing
equipment built in contemplation of potential expansion.

         Interest expense was $2,000 for fiscal 1995 as compared with no such
expense in fiscal 1994.

         The operating loss of $511,000 for fiscal 1995 increased by $143,000
or 38.9% over the operating loss of $368,000 in fiscal 1994.  The increase was
attributable primarily to payroll and related costs incurred because of USRR's
anticipation of opening a second manufacturing location.

         U.S. DRUG'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES

   
      U.S. Drug is a development stage enterprise with no earnings history and
which initially derived its capital resources from unsecured advances provided
by USAT.  During October and November, 1993, U.S. Drug sold 1,721,900 shares of
the U.S. Drug Common Stock to the public at $5.00 per share and for net
proceeds of approximately $7,099,000.  From the net proceeds of the offering
U.S. Drug repaid the advances made by USAT.  During fiscal 1996, U.S. Drug made
loans to USAT for working capital purposes in the amount of $1,428,538 and
received loan repayments from USAT in the amount of $1,634,762.  At March 31,
1996, the outstanding loan balance due from USAT was $282,295.  These advances
were evidenced by notes which became due on December 31, 1995, which maturity
date was extended to June 30, 1996, bearing interest at the rate of eight
percent per annum and secured by USAT's shares of the U.S. Drug Common Stock.
In June 1996, USAT repaid the indebtedness to U.S. Drug, the pledge of its
shares was released and USAT authorized a loan in the amount of $500,000 to
U.S. Drug, which indebtedness shall be due December 31, 1996 and will bear
interest at the rate of 8% per annum.

      In June 1995, the USAT License Agreement with the USN was renegotiated.
The amended agreement reduces minimum royalty guarantees to $100,000 per year,
representing a savings of $4,881,000 over the term of the agreement from the
minimum guaranty provision of the original agreement.  Additional royalties
will be paid only in conjunction with actual product sales.

      U.S. Drug will require additional capital to continue the research,
development and ultimate marketing of its products and to fund its working
capital requirements for the next 12 to 24 months.  U.S. Drug estimates that it
will require at least $4,500,000 to $5,000,000 during the next two years in
order to complete the development of the drug testing products.  The foregoing
estimate does not reflect an additional $2,000,000 to $2,500,000 required for
the manufacturing line start-up expenses.  U.S. Drug is currently conducting a
feasibility study with respect to the its drug testing product and, if the
results are unfavorable, the foregoing expenses will be unnecessary; however,
in such event U.S. Drug would have no products to market.  U.S. Drug expects to
derive the required funds from unsecured advances to be made by USAT.  USAT
intends to make such funds available to U.S. Drug from the net proceeds from
the private placement completed by USAT in February 1996, from the recent and
anticipated exercises of its USAT Common Stock purchase warrants
    

                                      146
<PAGE>   152
   
and stock options, from the revenues of its soon to be merged ProActive and RSA
subsidiaries and, if necessary, from additional debt or equity financings.
There can be no assurance that any of these additional sources of financing
will be available and, in such event, U.S. Drug will not be able to complete
its research and development on a timely basis.  There are currently no
unfunded commitments for capital expenditures.

CHANGES IN FINANCIAL CONDITION

      During fiscal 1996, U.S. Drug s investment in trading securities were
sold and U.S. Drug realized proceeds of $3,286,000 from the sale of the REMIC
bonds, resulting in a gain of $76,000 over the carrying value of the bonds on
the March 31, 1995 balance sheet.  U.S. Drug realized an overall loss of
$628,000 from its ownership of the bonds.  Management will make no further
investments in any high risk trading securities.  A brokerage loan payable in
the amount of $2,570,000 was repaid from the proceeds of the sale of the REMIC
bonds.


OPERATING CASH FLOWS

      Cash used for operations during fiscal 1996 amounted to $1,656,000.  The
net loss for the period was $1,641,000 and the adjustments to reconcile to net
cash owed by operating activities was $15,000.  The most significant
adjustments were decreases in use of cash provided by depreciation and
amortization of $144,000 and increases in accounts payable of $21,000 offset by
increases in the use of cash resulting from the gain on marketable securities
of $76,000, increases in prepaid expenses and other current assets of $56,000
and a decrease in accrued expenses of $50,000.

INVESTING CASH FLOWS

      Cash provided from investing activities was $3,248,000 during fiscal
1996.  Funds generated from the sale of the REMIC bonds in the amount of
$3,286,000 were offset by funds used to purchase property and equipment in the
amount of $22,000 and additional patent costs of $16,000.

FINANCING CASH FLOWS

     Cash used by financing activities amounted to $1,392,000 during fiscal
1996.  Cash from the sale of the REMIC bonds, included as an investing
activity, was used to pay off brokerage loans in the amount of $2,570,000 and
cash was  used for long term debt payments of $29,000.  Financing cash flows
were provided by additional proceeds from brokerage loans in the amount of
$1,000,000 and net repayment of loans from USAT in the amount of $207,000.

RESULTS OF OPERATIONS

   
FISCAL 1996 VS. FISCAL  1995

      During fiscal 1996, U.S. Drug continued as a development stage enterprise
with no revenues.  Selling, general and administrative expenses were $417,000
in fiscal 1996 as compared with $850,000 in fiscal 1995 or a decrease of
$433,000, resulting primarily from a $325,000 reduction in royalty payments on
the USAT license with the USN from $375,000 in fiscal 1995 to $50,000 in fiscal
1996.  Other selling, general and administrative expenses for fiscal 1996 were
comprised of royalty expenses of $62,000, rent, utilities and telephone charges
of $97,000, insurance expense of $35,000, marketing research expenses of
$44,000, legal and auditing services of $33,000, directors' fees of $10,000,
travel expenses of $24,000 and other expenses of $112,000.

      Research and development expenditures totaled $851,000 in fiscal 1996 as
compared with $886,000 in fiscal 1995.  The fiscal 1996 expenditures consisted
of payroll and fringe benefits of $593,000, outside consulting services of
$184,000 and other costs of $74,000.

      Depreciation expense decreased $19,000 from $163,000 in fiscal 1995 to
$144,000 in fiscal 1996 as some assets became fully depreciated during the
year.

      Management fees paid to USAT were $420,000 in both fiscal 1996 and fiscal
1995.  For a description of the services rendered under the management
agreement relating to these fees, see the section "Material
Contracts-Management Agreement" in Item 1 to this Report.

      Interest expense on brokerage loans were $72,000 during fiscal 1996 as
compared with $41,000 during fiscal 1995 or an increase of $31,000, resulting
from increased borrowings during fiscal 1996.

      Other income (expense) resulted in net income of $263,000 in fiscal 1996
as compared with net income of $31,000 in the prior year or an increase of

FISCAL 1995 VS. FISCAL 1994

   
      U.S. Drug, as a development stage enterprise had no revenues in fiscal
1995 or fiscal 1994.

      Selling, general and administrative costs were $850,000 in fiscal 1995 as
compared with $604,000 for the prior year or an increase of $246,000.  The
major component of their expenses was the royalty expense on the USAT license
with the USN which amounted to $375,000 in fiscal 1995 as compared to $229,000
in fiscal 1994 or an increase of $146,000.

      Research and development costs were $886,000 in fiscal 1995 as compared
with $728,000 in fiscal 1994 or an increase of $158,000, resulting primarily
from increased payroll costs.  Depreciation and amortization increased $71,000
from $92,000 in fiscal 1994 to $163,000 in fiscal 1995 primarily as a result of
a full year depreciation in fiscal 1995 of property acquired in the fourth
quarter of fiscal 1994.

      Management fees to USAT were $420,000 in both fiscal 1995 and fiscal
1994.

      Interest expense of $44,000 was incurred in fiscal 1995 as compared with
$32,000 in fiscal 1994.  Fiscal 1995 interest expense is comprised of $41,000
in interest on brokerage loans against the REMIC bonds and $3,000 of interest
on loans from USAT.  Fiscal 1994 interest relates to loans from USAT.

      Other income (expense) is comprised of income of $31,000 in fiscal 1995
as compared with expense of $384,000 in fiscal 1994.  Fiscal 1995 other income
(expense) consisted of interest income of $265,000, of which $245,000 was
primarily from the REMIC bonds and $20,000 was from advances to USAT less
unrealized losses on the REMIC bonds of $234,000.  The fiscal 1994 other income
(expense) is comprised of interest income of $86,000 primarily related to the
REMIC bonds and unrealized losses on these bonds of $497,000.
    

                     COMMISSION POSITION ON INDEMNIFICATION

        The USAT Board of Directors has authorized indemnification of directors
and officers of USAT to the fullest extent permitted by Delaware law.

        Section 145(a) of the GCL permits a corporation to indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
corporation), by reason of the fact that he or she is or was a


                                      149
<PAGE>   155
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred in connection with such action,
suit or proceeding if he or she acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful.

        Under Section 145(b) of the GCL, a corporation also may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he or
she is or was a director, officer, employee or agent of the corporation, or is
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if he or she acted in good faith and in a manner he or
she reasonably believed to be in, or not opposed to the best interests of the
corporation.  However, in such an action by or on behalf of a corporation, no
indemnification may be in respect of any claim, issue or matter as to which the
person is adjudged liable to the corporation unless and only to the extent that
the court determines that, despite the adjudication of liability but in view of
all the circumstances, the person is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper.

        In addition, under Section 145(f) of the GCL, the indemnification
provided by Section 145 shall not be deemed exclusive of any other rights to
which those seeking indemnification may be entitled under any by-law,
agreement, vote of stockholders or disinterested directors or otherwise, both
as to action in his or her official capacity and as to action in another
capacity while holding such office.

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of USAT
pursuant to the foregoing provisions, or otherwise, USAT has been advised that
in the opinion of the Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities (other than the
payment by USAT of expenses incurred or paid by a director, officer or
controlling person of USAT in the successful defense of any action, suit or
proceeding) is





                                      150
<PAGE>   156
asserted by such director, officer or controlling person in connection with the
securities being registered, USAT will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

                                 LEGAL MATTERS

        The validity of the securities offered hereby will be passed upon for
USAT by Gold & Wachtel, LLP, New York, New York.

        Rosenman & Colin, LLP, New York, New York have passed on certain legal
matters for U.S. Drug relating to the Merger and the tax consequences thereof
to the U.S. Drug Minority Stockholders.

                                    EXPERTS

   
        The audited financial statements appearing in this Consent Solicitation 
Statement/Prospectus and Registration Statement of U.S. Alcohol Testing of 
America, Inc. and U.S. Drug Testing, Inc. at March 31, 1996, and for the year 
then ended, have been audited by Ernst & Young LLP, independent auditors, and at
March 31, 1995, and for each of the two years in the period ended March 31,
1995, by Wolinetz, Gottlieb & Lafazan, P.C., independent certified public
accountants, as set forth in their respective reports thereon appearing
elsewhere herein, and are included in reliance upon such reports given upon the
authority of such firms as experts in accounting and auditing.
    


                             CHANGE IN ACCOUNTANTS

        On November 3, 1995, USAT named Ernst & Young LLP ("E&Y") as USAT's new
independent auditors for fiscal 1996 replacing Wolinetz, Gottlieb & Lafazan,
P.C. ("Wolinetz"), which firm had served as USAT's independent auditors since
USAT's inception.  The Board of Directors, which authorized the change on
November 1, 1995, indicated that, in making the replacement, the directors were
not acting because of any criticism of, or dispute with, Wolinetz, but because
they concluded that, at this stage of development for USAT and its
subsidiaries, the selection of a national firm like E&Y was in USAT's best
interests.

        The reports of Wolinetz on the financial statements of USAT for fiscal
1994 and fiscal 1995 did not contain an adverse opinion or a disclaimer of
opinion, nor was either report qualified as to uncertainty, audit scope or
accounting principles.  There had been no disagreements between USAT and
Wolinetz in fiscal 1994 and fiscal 1995 and any subsequent


                                      151
<PAGE>   157
interim period preceding the engagement of E&Y as the principal auditors on any
matter of accounting principles or practice, financial statement disclosure,
auditing scope or procedures.

        Wolinetz has filed a letter to the Commission stating that it agreed
with the above statements.

   
        USAT did not consult E&Y, prior to its engagement, regarding the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
USAT's financial statements, nor was a written report or oral advice provided
to USAT that E&Y concluded was an important factor considered by USAT in
reaching a decision as to an accounting, auditing or financial reporting issue.

                         REPORT OF INDEPENDENT AUDITORS





The Board of Directors
U.S. Alcohol Testing of America




We have audited the accompanying consolidated balance sheet of U.S. Alcohol
Testing of America Inc. and subsidiaries (the "Company") as of March 31, 1996,
and the statements of operations, stockholders' equity, and cash flows for year
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit. The financial statements of the Company for the
years ended March 31, 1995 and 1994, were audited by other auditors whose report
dated May 26, 1995, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the 1996 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of the Company and
subsidiaries at March 31, 1996, and the consolidated results of their operations
and their cash flows for the year ended March 31, 1996, in conformity with
generally accepted accounting principles.

             U.S. ALCOHOL TESTING OF AMERICA, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1996


NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation

                  The consolidated financial statements include the accounts of
U.S. Alcohol Testing of America, Inc. (the "Company") and its wholly and
majority owned subsidiaries. All significant intercompany accounts and
transactions are eliminated in consolidation.

  Industry Segment and Concentration of Risk

                  The Company, which operates in a single industry segment,
designs, manufactures, markets and services alcohol breath testing equipment,
which is either sold or placed on a cost per test basis with laboratories or
other users, and, through its ProActive Synergies Inc. ("ProActive") subsidiary
designs and administers drug testing and background checking services as a human
resources provider. Additionally, the Company's 67.0% owned subsidiary, U.S.
Drug Testing, Inc. ("U.S. Drug") (a development stage enterprise), is developing
a saliva based, on site drug testing system and, thereafter depending on the
successful completion, completing development of a urine based, on site drug
testing system. The Company performs ongoing credit evaluations of its customers
and generally does not require collateral. The Company maintains reserves for
potential credit losses, and such losses have been within management's
expectations. No customer accounted for 10% or more of net revenues in the years
ended March 31, 1996, 1995 or 1994.

                  Financial instruments that potentially subject the Company to
concentration of credit risk consist principally of cash investments and trade
receivables. The Company currently invests excess cash in short term commercial
paper with strong credit ratings and in money market accounts with commercial
banks.

                  The Company's operating results each quarter are subject to
various uncertainties, including uncertainties related to revenues from major
customers, actions of competitors and the risks inherent in the new product
development currently being undertaken by the Company's 67.0%-owned subsidiary,
U.S. Drug.

                  One of the significant risks potentially affecting the
Company's operating results is the effect of the history of operating losses on
its ability to secure additional capital resources. Management continues to
believe that the Company will have the cash resources to meet all of its
operating requirements for the next 12 months as a result of the exercise of
warrants to purchase its Common Stock, the anticipated growth of the human
resource provider portion of its business which is expected to benefit from the
acquisition of Robert Stutman & Associates, Inc. ( See Note 16-Subsequent
Events), increased sales of breath alcohol testing machines and cost per test
revenue, the discontinuance of the operations of its subsidiaries, U.S. Rubber
Recycling, Inc. ("USRR") and Good Ideas Enterprises, Inc. ("Good Ideas"), and
significant budgeted reductions in general and administrative costs.

  Use of Estimates

                  The preparation of financial statements in conformity with
generally accepted accounting principles required management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

  Cash and Cash Equivalents

                  The Company considers all highly liquid cash investments with
an original maturity of three months or less when purchased to be cash
equivalents.

  Trading Securities

                  Trading securities at March 31, 1995 consisted of
mortgage-backed debt and corporate equity securities. The Company adopted the
provisions of Statement of Financial Accounting Standards (SFAS) No. 115,
"Accounting for Certain Investments in Debt and Equity Securities", effective
April 1, 1994. Pursuant to SFAS No. 115, the provisions of the Statement were
not applied retroactively. The change had no material cumulative effect on the
Company's financial position or results of operations. Prior to the adoption of
SFAS No. 115, equity and debt securities were carried at the lower of aggregate
cost or market and on an amortized cost basis, respectively.

Under SFAS No. 115, the Company classified all of its debt and marketable equity
securities held at March 31, 1995 as trading securities and recorded them at
fair market value. Management determines the appropriate classification of all
securities at the time of purchase and reevaluates such designation as of each
balance sheet date. Unrealized holding gains and losses, net of the related tax
effect, are included in earnings.

NOTE 1 (CONTINUED)--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


  Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the
first-in, first-out method.

  Property and Equipment

Property and equipment is stated at cost. Depreciation is computed by both
straight-line and accelerated methods over the estimated useful lives of the
related assets. Expenditures for maintenance and repairs are charged to expense
as incurred whereas major betterments and renewals are capitalized.

The Company's property and equipment is depreciated using the following
estimated useful lives:

                                                  Life

Furniture and Fixtures                        5 -   7 Years
Equipment                                     5 -   7 Years
Equipment--Network/Per Test                   3 -   5 Years
Test Equipment                                      5 Years
Leasehold Improvements                        Life of Lease
Vehicles                                            5 Years

  Covenants Not to Compete

                  Covenants not to compete are amortized using the straight-line
method over five to eight years.

  Goodwill

                  Goodwill represents the excess of the cost of the businesses
acquired over the fair value of net identifiable assets at the date of the
acquisition and is amortized using the straight-line method over 5 to 15 years.

                  The Company continually monitors events and changes in
circumstances that could indicate carrying amounts of goodwill may not be
recoverable. When events or changes in circumstances are present that indicate
the carrying amount of goodwill may not be recoverable, the Company assesses
the recoverability of goodwill by determining whether the carrying value of such
goodwill will be recovered through undiscounted expected future cash flows after
interest charges associated with the business acquired. No impairment losses
were recorded by the Company in the years ended March 31, 1995 or 1994.

  Impairment of Long-Lived Assets

                  In March 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
("SFAS 121"), which is required to be adopted by the year ending March 31, 1997.
SFAS 121 establishes the accounting standards for the impairment of long-lived
assets, certain intangible assets and cost in excess of net assets acquired to
be held and used, and for long-lived assets and certain intangible assets to be
disposed of. The Company does not expect the adoption of SFAS 121 to have a
material impact on its financial statement.

  Patents

                  The cost of patents are amortized over their expected useful 
lives (approximately 17 years) using the straight-line method.

  Revenue Recognition

                  Sales are recorded as products are shipped. Per test revenues
are recognized in the period that such tests are performed.

  Research and Development Costs

                  Research and development costs are expensed as incurred.

NOTE 1 (CONTINUED)--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Income Taxes

                  The Company accounts for income taxes under Statement of
Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes". In
accordance with SFAS No. 109, deferred tax assets and liabilities are
established for the temporary differences between the financial reporting basis
and the tax basis of the Company's assets and liabilities at enacted tax rates
expected to be in effect when such amounts are realized or settled.

  Common Stock Issued for Services

                  The Company accounts for Common Stock issued for services
other than employment by charging income in the period of grant with the market
value of the Common Stock.

  Accounting for Stock Based Compensation

                  The Company accounts for Common Stock and warrants issued to
employees as compensation in accordance with the provisions of the Accounting
Principles Board Opinion No. 25 (APB 25) "Accounting for Stock Issued to
Employees." In 1995, the Financial Accounting Standards Board released SFAS No.
123, "Accounting for Stock-Based Compensation." SFAS No. 123 provides an
alternative to APB 25 and is effective for fiscal years beginning after December
15, 1995. The Company expects to continue to account for its grants of Common
Stock or warrants to employees in accordance with the provisions of APB 25.
Accordingly, SFAS No. 123 is not expected to have any material impact on the
Company's financial position or results of operations.

  Net Loss Per Common Shares

                  Loss per common share is based upon the weighted average
number of common shares outstanding during the periods reported. Common stock
equivalents have not been included in this calculation since their inclusion
would be antidilutive.

  Reclassification

                  The Company has reclassified certain prior year balances to
conform with the current year's presentation.

NOTE 8--MINORITY INTEREST

                  The Company's consolidated financial statements at March 31,
1995 include 100% of the assets, liabilities and losses of U.S. Drug, a
67.0%-owned publicly traded subsidiary, and 100% of the assets, liabilities and
losses of Good Ideas, a 59%-owned publicly traded subsidiary. The percentage
ownership in Good Ideas decreased by 1% during the year ended March 31, 1995 by
virtue of an additional 65,200 shares of common shares of the subsidiary sold
pursuant to the overallotment provision of its initial public offering. The
$2,723,502 minority interest reported on the balance sheet represents the
minority stockholders' interest in the equity of these subsidiaries.

                  At March 31, 1996, the Company's consolidated statements
reflect an increase in the minority interest in Good Ideas as a 60.8%-owned
subsidiary as a result of the surrender of 126,520 shares of common stock of
Good Ideas in connection with the resignation of Keith Parten, formerly Chief
Operating Officer, President and a director of Good Ideas, and the issuance of
10,000 shares of common stock of Good Ideas to an officer for compensation.

                  See Note 16 for information regarding the Company's
registration statements under the Securities Act of 1933, as amended (the
"Securities Act"), in connection with the offer to purchase the minority shares
of U.S. Drug and Good Ideas.

  Initial Public Offering of Good Ideas

                  In February 1994, the initial public offering of Good Ideas
was completed and 1,200,000 shares of the common stock of Good Ideas was sold to
the public at $5 per share for gross proceeds of $6,000,000. Net proceeds to the
subsidiary amounted to approximately $4,735,000 after deducting expenses of

connection with the offering, the underwriter was granted, for nominal
consideration, common stock purchase warrants entitling the underwriter to
purchase up to 120,000 shares of common stock of Good Ideas at $6 per share.

                  In April 1994, an additional 65,200 shares of common stock of
Good Ideas were sold pursuant to its initial public offering's overallotment
provision and the subsidiary grossed $326,000 before deducting expenses of
approximately $45,000.

                  As a result of the initial public offering and overallotment,
approximately $2,800,000 was added to the additional paid-in-capital of the
Company. After completion of the overallotment, the Company's ownership of Good
Ideas was reduced to 59%.

  Initial Public Offering of U.S. Drug Testing, Inc.

                  U.S. Drug completed its initial public offering of 1,500,000
shares of common stock at $5 per share on October 13, 1993 and the subsequent
overallotment of 221,900 shares in November 1993. U.S. Drug realized gross
proceeds of $8,609,500 and incurred expenses of $1,501,500, yielding net

  Alconet and Dakotanet Acquisitions

                  On March 30, 1995, the Company acquired 100% of the
outstanding capital stock of Alconet, Inc., a privately held North Dakota
corporation ("Alconet"), and 100% of the net equity of Dakotanet, LLC, a
privately held North Dakota Limited Liability company ("Dakotanet"). The
transactions provided for the issuance of 782,321 shares of the Common Stock
valued at $1,565,000. In connection with the transaction certain of the shares
issued by the Company to the selling shareholders of Alconet were used as
payment of obligations of Alconet in the approximate amount of $109,000.
Concurrent with the acquisitions, the Company contributed the net assets of
Dakotanet to Alconet. The purchase price of the acquisitions exceeded the net
book value of the assets acquired, which included cash of $593,000, by $818,000
and this has been assigned to goodwill. The acquisitions have been accounted for
as a purchase.

  Private Placements

                  In August 1995, the Company completed a private placement to
international investors, who were not related to the Company, in accordance with

          WARRANTS

                  The Company has adopted an Employees' Incentive Compensation
Plan ("the Plan"). The Plan provides for the issuance of restricted stock to
employees under certain conditions, as well as non-qualified stock options and
Incentive Stock Options.

                  There are reserved 450,000 shares of Common Stock for issuance
upon the exercise of non-qualified and incentive options and the grant of
restricted stock under the plan. During August 1994, stock options to purchase
all of the 450,000 shares of Common Stock reserved for issuance under the Plan
were granted to key officers and directors of the Company in recognition for
services rendered to the Company. These options are immediately exercisable at
$2.38 per share, which represented the market value at the date of grant. The
options expire after ten years.

NOTE 11--SETTLEMENT OF LITIGATION


                  In November 1993, the Company and Jeffrey Brooks Securities,
Inc., its former investment banker, and Jeffrey Brooks individually
(collectively "Brooks") resolved a dispute which provided, in pertinent part,
that Brooks exercise an option to purchase 21 Units of securities issued by the
Company's international subsidiary ("NV") for $577,500 and thereafter convert
those shares to Common Stock at the same conversion price of $1.17. As a result,
Brooks was issued 493,590 shares of the Common Stock.

                  In November 1993, the Company executed a stipulation of
settlement in the securities class action litigation which was subject to Court
approval. The Company agreed to pay $1,600,000 in cash to the class and
$3,000,000 worth of its Common Stock, or a total consideration of $4,600,000 to
completely settle both class actions then pending against the Company and all
defendants. This amount was charged to operations during the year ended March
31, 1994. The Company funded the $1,600,000 cash portion through exercised
warrants and options of certain co-defendants in the class action.

                  On April 4, 1994, the Court approved the stipulation of
settlement entered into by the Company in November 1993. The Court chose March
31, 1994 as the valuation date for the $3,000,000 stock portion of the
settlement. Accordingly 1,333,333 shares of Common Stock were issued based upon
the $2.25 closing price at March 31, 1994. These shares have not been included
in the computation of earnings (loss) per share for the year ended March 31,
1994 because the number of shares were not determinable until the date of the
court approval. If these shares were outstanding for the entire year ended March
31, 1994, the effect on loss per share would have been to decrease the net loss
per share by $.03.

                  In November 1993, as part of a dispute resolution with its
former consultant, David Brooks, the Company received all of Mr. Brooks' 25%
equity interests in both NV and Good Ideas for nominal consideration. As a
result, the Company's interests became 100% of NV and 60% percent of Good Ideas.

                  In September 1995, the Company settled litigation relating to
a consent solicitation filed against it by a group of stockholders. Term of the
settlement included the payment of legal costs of the stockholder group. The
costs incurred by the Company and the stockholder group totaled approximately
$1,000,000 and are included in the caption "Loss from Settlement of Litigation."

                  In January 1996, the Company settled litigation with a former
consultant, Jonathan J. Pallin, with the payment of $175,000 cash and the
issuance of warrants to purchase 150,000 shares of the Common Stock at a price
of $2.25 per share though January 30, 2000. Warrants to purchase 200,000 shares
of the Common Stock at $2.625 were returned to the Company and canceled as part
of the settlement. The cash payment related to this settlement is included in
Additional Paid In Capital.

                  In March 1996, the Company settled litigation with two former
officers of Alconet. The settlement resulted in payments by the Company of
$250,000. These costs are included in the caption "Loss from Settlement of
Litigation."

                  The Company and its subsidiaries have entered into employment
agreements with certain of its officers and employees which will terminate at
various dates through the end of December 1997. The agreements provide for

reimbursement of related business expenses incurred.

  Royalty Agreement

                  As part of the acquisition of certain assets of Luckey
Laboratories, Inc., during June 1988 and a covenant not to compete provision by
Manley Luckey, principal of Luckey Laboratories, Inc. the Company was obligated
to pay royalties equal to 5% of the first $1,000,000 in sales, 3% of the second
$1,000,000 in sales and 2% of sales exceeding $2,000,000, with a maximum
guaranteed annual royalty of $120,000. Guaranteed minimum royalties of $30,000
per year were payable at the rate of $2,500 per month, through June 30, 1993, as
amended. The royalty terms extend for Manley Luckey's lifetime with no minimum
guarantee after June 1993, but were limited to $120,000 per year or 3% of gross
sales, whichever is less. In anticipation of increased revenues which would
result in the payment of the maximum royalty under the existing agreement, in
September 1994, the Company renegotiated the terms of the agreement to provide
monthly payments of $5,000 for the period from September through December, 1994
and $10,000 per month from January 1, 1995. The agreement also provides for a
CPI adjustment every six months starting June 1, 1995. Had the terms of the
revised royalty agreement been in effect for the last three years, royalty
expense would have increased by $57,500 for the year ended March 31, 1995 and
$90,000 for each of the years ended March 31, 1994 and 1993. Royalties charged
to operations under this agreement amounted to $122,700,$62,500 and $30,000 for
the fiscal years ended 1996, 1995 and 1994, respectively.

  Lease Commitments

                  The Company has entered into a lease that commenced July 1,
1991 and terminates on January 31, 1997 as amended, for new office and factory
facilities in Rancho Cucamonga, California. The lease as amended provides for
annual rental payments commencing November 1, 1991. Two of the Company's
subsidiaries maintain facilities under leases expiring over periods through June
1999. In addition to rent, the leases provide for payment of real estate taxes
and other occupancy costs.

                  Approximate future minimum payments under these leases are
summarized as follows:

</TABLE>


                  Rent expense was approximately $293,000, $276,000, and
$283,000 for the years ended March 31, 1996, 1995 and 1994, respectively.

                  Although the purchaser of the discontinued USRR business has
assumed the lease of the building the business occupied, the landlord did not
release USRR from liability on the lease if the purchaser does not perform.

  Material Contracts

                  The Company and the Department of the Navy, on January 24,
1992, entered into a ten-year agreement granting the Company a partial exclusive
patent license to products for drug testing in the United States and certain
foreign countries. In June 1995, USAT's License Agreement with the Department of
Navy was renegotiated and amended to provide for minimum royalties of $100,000
per year commencing October 1, 1995 and terminating September 30, 2005.
Additional royalties will be paid pursuant to a schedule based upon sales of
products. U.S. Drug is a sub-licensee under this agreement from USAT and,
accordingly, has an obligation to USAT for the royalty payments required by the
License Agreement. Royalties paid under the License Agreement by the Company
amounted to $50,000 for the year ended March 31, 1996, $375,000 for the year
ended March 31, 1995 and $228,750 for the year ended March 31, 1994.

NOTE 12 (CONTINUED)--COMMITMENTS AND CONTINGENCIES

  Network/Per Test Equipment Agreements

                  In December 1994, the Company entered into Equipment,
Licensing, Service and Maintenance Agreements with two national laboratories
("the Customers") for three and five- year terms, respectively. Under the terms
of these agreements, the Company delivered its Alco Analyzer 2100 Unit, together
with related software and equipment, to various testing sites of the Customers,
as outlined in the agreements. The Company granted to the Customers a
nonexclusive, nontransferable license to use the equipment as specified in the
agreements. In addition, the Company shall provide to the Customers technical
services, disposable supplies and maintenance as specified in the agreements.
The Company will be compensated under the terms of the agreements by receiving a
fee for each test performed on its equipment.

NOTE 13--INCOME TAXES

                  The Company and its subsidiaries file their corporation income
tax returns on an unconsolidated basis and have net operating loss carryforwards
at March 31, 1996 of approximately $35,600,000, expiring from March 31, 2004 to
March 31, 2011 if not offset against future federal taxable income.

                  Pursuant to Section 382 of the Internal Revenue Code, due to
changes in the ownership of the Company and its subsidiaries, the utilization of
these loss carryforwards may be subject to an annual limitation.

                  Income tax benefit attributable to net loss differed from the
amounts computed by applying the statutory Federal Income tax rate applicable
for each period as a result of the following:

                  In February 1996, Lee S. Rosen, a director of the Company,
received $100,000 and warrants to purchase 700,000 shares of Common Stock for
services performed in connection with the Company's offering of Common Stock

during May and June 1996, Mr. Rosen received an additional $400,000 for services
rendered to the Company in connection with the exercise of Common Stock purchase
warrants (See Note 16 to the Financial Statements). The payments to Mr. Rosen
have been charged to Additional Paid-In Capital.

NOTE 15  DISCONTINUED OPERATIONS

                  On February 26, 1996, the Board of Directors approved a
strategic decision to focus on the Company's core alcohol, drug and human
resource provider businesses and to dispose of its non core rubber recycling and
toy operations, namely USRR and Good Ideas. These business units are accounted
for as discontinued operations and, accordingly, their operations are segregated
in the accompanying income statements. Sales, operating costs and expenses,
other income and expense and applicable minority share of losses for the years
March 31, 1995 and 1994 have been reclassified for amounts associated with
discontinued units. All operations for USRR and Good Ideas have been classified
as Loss from Discontinued Operations.

                  Discontinued operations include management's best estimates of
the amounts expected to be realized from the sale or liquidation of its toy
operations. The amounts the Company will ultimately realize could differ in the
near term from the amounts assumed in arriving at the loss on disposal of the
discontinued operations.

                  Sales, related losses and minority share of losses associated
with the discontinued business units are as follows:

NOTE 16--SUBSEQUENT EVENTS

  Management Changes

On April 18, 1996, James C. Witham and Karen B. Laustsen both submitted their
resignations from their respective positions as executive officers and directors
of the Company.

On the same date the following executive appointments were announced:

Robert Stutman was elected to the Board of Directors, elected Chairman of the
Board and designated as Chief Executive Officer of the Company. Terms of
compensation for Mr. Stutman include a base salary of $225,000 plus cash bonuses
based upon attainment of business objectives. Terms of employment include a
provision that, in the event of termination without cause prior to April 17,
1999, Mr. Stutman receives severance pay in the amount of his current base pay
on the effective termination date through April 17,1999.

Linda H. Masterson was elected President and designated its Chief Operating
Officer of the Company effective May 13, 1996. Terms of employment include a
base salary of $175,000 and a grant of warrants to purchase 600,000 shares of
the Common Stock at $3.125 exercisable over a four-year period. Terms of
employment include a provision that, in the event of termination without cause,
Ms. Masterson receives severance pay in the amount of one-year's base pay in
effect on the termination date.

  Discontinued Operations

On April 30, 1996, the Company's subsidiary, USSR, completed the sale of certain
of its assets, net of trade payables of $79,000, to Reclamation Resources, Inc.,
a private California corporation, for $150,000 cash and a $300,000 secured
promissory note bearing interest at the rate of 7% per annum, with annual
payments of $50,000 plus interest. The note contains a prepayment clause that
enables USRR to receive 12 1/2% of product sales in excess of $1,400,000.

  Filing of S-4 Forms

During April and May, 1996, the Company filed two Registration Statements on
Form S-4 under the Securities Act in an attempt, through consent solicitations,
to acquire the common shares owned by the minority interests of U.S. Drug, its
67.0% owned public subsidiary, and Good Ideas, its 60.8% owned public
subsidiary. If the Company is successful, it will own 100% of these
subsidiaries. There is no assurance that either consent solicitation will be
successfully completed.

  Acquisition of Robert Stutman & Associates, Inc.

On April 18, 1996, the Board of Directors approved, in principle, the
acquisition of Robert Stutman & Associates, Inc. ("RSA"), a provider of
corporate "Drug Free Workplace" programs. Robert Stutman served as President of
RSA and was its largest stockholder. The acquisition was completed May 21, 1996.
The purchase price was comprised of $2,100,000 in cash, $400,000 in notes,
500,000 shares of the Company's Common Stock and Common Stock purchase warrants
to acquire 900,000 shares of the Company's Common Stock at $ 3.125 per share,
which was the closing sales price of the Common Stock on April 17, 1996.

                  Proforma combined results of operations for the Company and
RSA have not been presented herein because, prior to its acquisition by USAT on
May 21, 1996, RSA was a Subchapter S corporation and distributed substantially
all of its income to its shareholders. As a result of these distributions,
proforma financial information would not affect reported earnings per share.

                  Pursuant to the acquisition of RSA, Brian Stutman, who is the
son of Robert Stutman and was a shareholder of RSA, has been employed by USAT as
its Director of Sales and Marketing. Brian Stutman's compensation agreement
provides for an annual salary of $130,000, a bonus upon achievement of
goals for the year ending March 31, 1997 and a one-time cash bonus of $30,000
upon ProActive satisfying certain performance standards. In the event that Brian
Stutman is terminated without cause (as defined) during the first three years
that he is employed by the Company, he shall receive severance pay in an amount
equal to the base salary that would have been paid to him after the date of
termination had he not been terminated and had he been employed by USAT for a
period of three years ending May 20, 1999.

  Exercise of Warrants and Options

                  From April 1, 1996 through June 5, 1996, the Company has
received gross proceeds of $4,242,000 from the exercise of warrants and options

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

The Board of Directors 
U.S. Drug Testing, Inc.

We have audited the accompanying balance sheet of U.S. Drug Testing, Inc. (a
development stage enterprise) (the "Company") as of March 31, 1996, and the
related statements of operations, stockholders' equity, and cash flows for the
year ended, and for the period October 8, 1992 (inception) through March 31,
1996.  These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements based on our audit. The financial statements as of and for the two
years in the period ended March 31, 1995, were audited by other auditors whose
report dated May 26, 1995 expressed an unqualified opinion on those statements. 
The financial statements for the period October 8, 1992 (inception) through
March 31, 1995 include total costs and expenses and net loss of $4,497,000 and
$4,850,000 respectively.  Our opinion on the statements of operations, and cash
flows for the period Optober 8, 1992 (inception) through March 3, 1995, insofar
as it relates to amounts for prior periods through March 31, 1995, is based
solely on the report of other auditors.

We conducted our audit in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audit and the report of other
auditors provide a reasonable basis for our opinion.

In our opinion, based on our audit and the report of other auditors, 
the financial statements referred to above present fairly, in all materials 
respects, the financial position of U.S. Drug Testing, Inc. at March 31, 1996, 
and the results of its operations and its cash flows for the year then ended 
and the period from October 8, 1992 (inception) through March 31, 1996 in 
conformity with generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

                                 MARCH 31, 1996



NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Organization and Business

         U. S. Drug Testing, Inc. ("the Company") was incorporated on October 8,
1992 under the laws of the State of Delaware as a wholly-owned subsidiary of U.
S. Alcohol Testing of America, Inc. ("USAT"), a publicly-owned corporation and
is presently a 67.0%-owned subsidiary of USAT (see Note 8). The Company
commenced activities on January 1, 1993 and is engaged in the design of certain
patented technology known as the "Flow Immunosensor" developed by U.S. Navy
Department scientists for the detection of drugs of abuse. As the Company is
devoting its efforts to research and the development of its products and there
has been no revenue generated from product sales as yet, the Company's financial
statements are presented as statements of a development stage enterprise.

         The Company will require additional capital to continue the research,
development and ultimate manufacture and marketing of its product and to fund
its working capital requirements for the next 12 months and expects to derive
these funds from unsecured advances to be made by USAT. USAT intends to make
such funds available to the Company from the net proceeds from the private
placement completed by USAT in February 1996, from the anticipated exercises of
its USAT common stock purchase warrants and stock options, from the revenues of
its ProActive Synergies, Inc. subsidiary and, if necessary, from additional debt
or equity financings. There can be no assurance that any of these additional
sources of financing will be available and, in such event, the Company will not
be able to complete its research and development on a timely basis.

Concentration of Credit Risk

         Financial instruments that potentially subject the Company to
concentration of credit risk consist of the note receivable from USAT.

Use of Estimates in the Preparation of Financial Statements

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

  Cash and Cash Equivalents

         The Company considers all highly liquid cash investments with an
original maturity of three months or less when purchased to be cash equivalents.


  Trading Securities

         Marketable securities at March 31, 1995 consisted of mortgage-backed
debt securities. The Company adopted the provisions of Statement of Financial
Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt
and Equity Securities, effective April 1, 1994. Pursuant to SFAS No. 115, the
provisions of the Statement were not applied retroactively. The change had no
material cumulative effect on the Company's financial position or results of
operations.

         Prior to the adoption of SFAS No. 115, debt securities were carried at
the lower of aggregate cost or market and on an amortized cost basis,
respectively. Under SFAS No. 115, the Company classifies all of its debt
securities as trading securities. Management determines the appropriate
classification of all securities at the time of purchase and reevaluates such
designation as of each balance sheet date. The Company's trading securities are
recorded at fair value. Unrealized holding gains and losses, net of the related
tax effect, are included in earnings.


  Property and Equipment

         Property and equipment is stated at cost. Depreciation is computed by
the straight-line method over the estimated useful lives of the related assets
which range from 5 to 13 years. Expenditures for maintenance and repairs are
charged to expense as incurred whereas major betterments and renewals are
capitalized.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                                 MARCH 31, 1996

NOTE 1--(CONTINUED) --SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Patents

         The costs of patents is being amortized over its expected useful life
of 17 years using the straight-line method.


  Research and Development Costs

         Research and development costs are expensed currently.

  Accounting for Stock Based Compensation

         The Company accounts for shares of its Common Stock, $.001 par value
(the "Common Stock"), and warrants issued to employees as compensation in
accordance with the provisions of the Accounting Principles Board Opinion No. 25
(APB 25) "Accounting for Stock Issued to Employees." In 1995, the Financial
Accounting Standards Board released SFAS No. 123, "Accounting for Stock-Based
Compensation." SFAS No. 123 provides an alternative to APB 25 and is effective
for fiscal years beginning after December 15, 1995. The Company expects to
continue to account for its grants of Common Stock or warrants to employees in
accordance with the provisions of APB 25. Accordingly, SFAS No. 123 is not
expected to have any material impact on the Company/s financial position or
results of operations.

  Net Loss Per Common Share

         Loss per common share is based upon the weighted average number of
common shares outstanding during the periods reported. Common stock equivalents
have not been included in this calculation since their inclusion would be
antidilutive.

  Income Taxes

         The Company accounts for income taxes under Financial Accounting
Standards Statement No. 109, "Accounting for Income Taxes". The objective of the
asset and liability method used under Statement No. 109 is to establish deferred
tax assets and liabilities for the temporary differences between the financial
reporting basis and the tax basis of the Company's assets and liabilities at
enacted tax rates expected to be in effect when such amounts are realized or
settled.

         On October 5, 1993, the Company completed an initial public offering of
its Common Stock. The Company sold 1,500,000 shares at $5.00 per share and

NOTE 8 -- (CONTINUED)--STOCKHOLDERS' EQUITY

         The principal features of the Option Grant Program may be summarized as
follows:

         Options granted under the Option Grant Program may be either incentive
stock options designed to meet the requirements of Section 422 of the Internal
Revenue Code or non-statutory options not intended to satisfy such requirements.
The exercise price per share for incentive stock options will not be less than
one hundred percent (100%) of the fair market value per share of the Common
Stock on the grant date. For non-statutory options, the exercise price per share
may not be less than eighty-five (85%) of such fair market value. No granted
option will have a maximum term in excess of ten (10) years.

         In October 1994, the Board of Directors granted stock options to
purchase 252,000 shares at an exercise price of $7.00 per share to certain
officers, directors and key employees of the Company.

NOTE 10--COMMITMENTS AND CONTINGENCIES

Employment Agreement

      The Company has entered into a three-year employment agreement with one of
its officers which will terminate during July 1997. The agreement provided for
an annual minimum salary in the amount of $117,000 as well as for reimbursement
of related business expenses incurred. Terms of employment were amended
subsequent to the end of the fiscal year (see Note 11.)

  Lease Commitments

         The Company has entered into an agreement with USAT commencing January
1, 1993 and terminating on January 31, 1997, subject to two five-year renewal
options, sub-leasing a portion of USAT's office and factory facilities in Rancho
Cucamonga, California. In addition to rent, the Company will pay for its
proportionate share of real estate taxes and other occupancy costs. Rent expense
for the fiscal years ended March 31, 1996, 1995 and 1994 was $36,000, $54,000
and $52,000, respectively.

         Approximate future minimum payments under this sub-lease are summarized
as follows:

            April 1, 1996 --March 31, 1997                             $62,500

         Rent has been generally allocated between USAT and the Company on the
basis of approximate square feet occupied--50% USAT, 50% the Company.

         Telephone is allocated on a 50%-50% basis.


Material Contracts

         Effective January 1, 1993 the Company entered into a sub-license
agreement with USAT in which the Company sublicensed all of USAT's rights under
a license agreement with the Department of the Navy (the "License Agreement").

         USAT and the Department of the Navy on January 24, 1992 had entered
into a ten-year agreement granting USAT a partial exclusive patent license to
products for drug testing in the United States and certain foreign countries. In
June 1995, USAT's License Agreement with the Department of Navy was renegotiated
and amended to provide for minimum royalties of $100,000 per year commencing
October 1, 1995 and terminating September 30, 2005. Additional royalties will be
paid pursuant to a schedule based upon sales of products. U.S. Drug is a
sub-licensee under this agreement from USAT and, accordingly, has an obligation
to USAT for the royalty payments required by the License Agreement. Royalties
paid under the License Agreement by the Company amounted to $50,000 for the year
ended March 31, 1996, $375,000 for the year ended March 31, 1995 and $228,750
for the year ended March 31, 1994.

Management Agreement

         On April 1, 1993, the Company entered into a management agreement with
USAT which obligated the Company to pay ten (10%) percent of its product sales
in exchange for administrative management services to be provided by USAT. The
minimum annual management fee had been set at $300,000.

         During July, 1993, the Company amended the management agreement with
USAT. Under the terms of the revised agreement, which is retroactive to April 1,
1993, the Company is obligated to pay a fixed annual management fee of $420,000
plus three (3%) percent of its gross revenues. The term of the amended agreement
is five years from April 1, 1993. The Company paid $420,000 per year for the
years ended March 31, 1996, 1995, and 1994.

NOTE 11 - SUBSEQUENT EVENTS

         During May, 1996 USAT filed a Registration Statement on Form S-4 under
the Securities Act of 1933, as amended, in an attempt, through a consent
solicitation, to acquire the Common Stock of the Company owned by the minority
interest and thereby own 100% of the Company's Common Stock. There can be no
assurance that such solicitation will be successfully completed.

         During May 1996, James C. Witham tendered his resignation as Chairman,
Chief Executive Officer and a director of the Company and Karen B. Laustsen
tendered her resignation as a director of the Company. Mr. Witham has been

Laustsen was replaced by Linda H. Masterson, President, Chief Operating Officer
and a director of USAT. Michael S. McCord was added to the Board of Directors in
May.

         During May 1996, the terms of employment with an officer were amended
to provide for a minimum salary of $130,000 per year and severance pay equal to
a year if terminated due to acquisition or required relocation during the first
year and severance equal to six months pay if terminated thereafter.

               (b)   Acquisition Corp. as the surviving corporation, shall 
continue its corporate existence under the laws of the State of Delaware and
shall possess all of the rights, privileges, immunities, powers, franchises and
authority (both public and private) of, and be subject to all of the
restrictions, disabilities and duties of, U.S. Drug;

               (c)   all of the assets and property of U.S. Drug of every kind,
nature and description (real, personal and mixed and both tangible and
intangible) and every interest therein, wheresoever located, including, without
limitation, all debts or other obligations belonging or due to U.S. Drug, all
stock subscriptions, claims and choses in action shall be, and be deemed to be,
vested, absolutely and unconditionally, in Acquisition Corp. (to the same
extent, degree and manner as previously vested in U.S. Drug); and

               (d)   all debts and obligations of U.S. Drug, all rights of 
creditors of U.S. Drug and all liens or security interests encumbering any of
the property of U.S. Drug shall be vested in Acquisition Corp. and shall remain
in full force and effect without modification or impairment and shall be, and be
deemed to

be, enforceable against Acquisition Corp. and its assets and properties with the
same full force and effect as if such debts, obligations, liens or security
interests had been originally incurred or created by Acquisition Corp. in its
own name and for its own behalf. Without limiting the generality of the
foregoing, Acquisition Corp. specifically assumes all continuing obligations
which U.S. Drug would otherwise have to indemnify its officers and directors, to
the fullest extent currently provided in Acquisition Corp.'s By-Laws and
pursuant to the GCL, with respect to any and all claims arising out of actions
taken or omitted by such officers and directors prior to the Effective Date.

         2.   INSTRUMENTS OF CONVEYANCE. Without limiting the generality of the
provisions of Section 1 hereof and/or the succession provisions of applicable
law, the officers and directors of U.S. Drug last in office shall (to the extent
they, or any of them, possess and/or may exercise the power to do so) execute,
deliver and/or record such deeds and/or other instruments of transfer and/or
conveyance, and take or cause to be taken, such other and further actions, as
the case may be, as shall be reasonably requested by Acquisition Corp. or USAT,
or their legal counsel, to vest, perfect, confirm, implement the transfer of, or
establish in the name, on behalf or for the account or the benefit of
Acquisition Corp., title and/or possession of any or all of the assets,
property, property interests, rights, privileges, immunities, powers and
franchises owned and/or exercisable by U.S. Drug (or in which U.S. Drug had an
interest and/or the power to exercise immediately prior to the Effective Date)
and which was vested, or intended to be vested, in Acquisition Corp. pursuant to
the provisions of this Agreement and the Merger.

         3.   CONSTITUTIONAL DOCUMENTS, DIRECTORS AND OFFICERS.  On and as of 
the Effective Date:

              (a)   The Certificate of Incorporation of Acquisition Corp. on
such date in full force and effect shall be the Certificate of Incorporation of
Acquisition Corp., as the surviving corporation, until the same shall be
altered, amended, modified, terminated or rescinded in the manner provided by
the GCL, which rights of alteration, amendment, modification, termination and/or
rescission are hereby expressly reserved by Acquisition Corp.;

              (b)   The By-Laws of Acquisition Corp. on such date in full force 
and effect shall be the By-Laws of Acquisition Corp., as the surviving
corporation, until the same shall be altered, amended, modified, terminated or
rescinded in the manner provided in the Certificate of Incorporation of
Acquisition Corp. and/or the GCL, which rights of alteration, amendment,
modification,

                                                                           E-3
                                       3                        Page      of 103
<PAGE>   196
termination and/or rescission are hereby expressly reserved by Acquisition Corp.

              (c)   The members of the Board of Directors and the officers of
Acquisition Corp., the surviving corporation, shall consist of the persons
described on Exhibit "A" annexed hereto and made a part hereof, each of such
persons to hold such membership and/or officership as provided in the By-Laws
and/or the GCL.

              (d)   The Certificate of Incorporation of USAT on such date in
full force and effect shall be the Certificate of Incorporation of USAT until
the same shall be altered, amended, modified, terminated or rescinded in the

              (e)   The By-Laws of USAT on such date in full force and effect
shall be the By-Laws of USAT until the same shall be altered, amended, modified,
terminated or rescinded in the manner provided in the Certificate of
Incorporation of USAT and/or the GCL, which rights of alteration, amendment,
modification, termination and/or rescission are hereby expressly reserved by
USAT.

         4.   CONVERSION RATES. On the Effective Date the shares of the U.S. 
Drug Common Stock shall be converted and exchanged into shares of the USAT
Common Stock (and options, warrants and similar rights exercisable with respect
to shares of the U.S. Drug Common Stock shall become exercisable with respect to
shares of the USAT Common Stock) in the following manner:

              (a)   Each issued and outstanding share of the U.S. Drug Common
Stock shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted and exchanged into a number of shares of the USAT
Common Stock having a value of $5.25 per share; provided however, that to the
extent any holder of the U.S. Drug Common Stock shall be entitled, as a result
of the foregoing conversion and exchange, to receive less than a whole share of
the USAT Common Stock, then and in any such event:

                    (i)   no fractional share and/or fractional interest in a 
whole share shall be issued and

                    (ii)  the fractional interest of such holder shall be 
liquidated for cash equivalent calculated on the basis of the closing sales
price of the USAT Common Stock on the Effective Date or on the first day
thereafter that such price is available.

                                                                            E-4
                                       4                        Page      of 103
<PAGE>   197
The number of shares of the USAT Common Stock to be exchanged for each share of
U.S. Drug Common Stock shall be determined by dividing $5.25 by the average of
the closing sales prices per share of the USAT Common Stock as reported on the
American Stock Exchange during the 30 calendar days prior to the record date set
by the Board of Directors of U.S. Drug pursuant to Section 213 of the GCL for
the solicitation of consents pursuant to Section 228 of the GCL for the adoption
of the Merger pursuant to Section 251 of the GCL.

              (b)   Each warrant expiring October 13, 1998 (the "Warrant") 
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted and exchanged into a warrant (the "Merger Warrant") to
purchase shares of USAT Common Stock equal to the number of shares that the
holder would have received under Section 4(a) hereof had the Warrant been
exercised immediately prior to the Effective Date. The exercise price shall be
adjusted to the product of $7.50, and a fraction, the numerator of which shall
be the number of shares of the U.S. Drug Common Stock issuable upon exercise of
the Warrant prior to the Merger and the denominator will be the number of shares
of the USAT Common Stock issuable upon the exercise of the Merger Warrant. The
expiration date shall not be changed.

              (c)   Each option and similar right to purchase shares of the U.S.
Drug Common Stock shall become exercisable immediately prior to the Effective
Date and, if not exercised into shares of the U.S. Drug Common Stock on or
before the Effective Date, shall be canceled.

              (d)   Anything in this Section 4 to the contrary notwithstanding:

                    (i)    Any and all issued shares of the U.S. Drug Common 
Stock owned by U.S. Drug and held as treasury stock shall be canceled and
retired and no shares of the USAT Common Stock shall be issued with respect
thereto;

                    (ii)   Any and all issued shares of the U.S. Drug Common 
Stock owned by USAT shall be canceled and retired and no shares of the USAT
Common Stock shall be issued to USAT with respect thereto;

                    (iii)  U.S. Drug shall secure from each person who holds an 
option to purchase shares of the U.S. Drug Common Stock and who is a current or
former director of U.S. Drug a waiver of the option so that it is not assumed by
USAT or exercisable by the holder thereof; and

                    (iv)   Upon the issuance of shares of the USAT Common Stock 
to the U.S. Drug Minority Stockholders in exchange

                                                                           E-5
                                       5                        Page      of 103
<PAGE>   198
for their shares of the U.S. Drug Common Stock, there shall be credited to the
capital account of USAT an amount equal to the average of the closing sales
prices per share of the USAT Common Stock as determined in accordance with
subsection (a) of this Section 4 and, of the amount so credited, the portion
thereof in excess of the aggregate par value thereof shall be credited to the
capital surplus account.

         5.   APPOINTMENT OF EXCHANGE AGENT.  Prior to the Effective Date USAT 
shall, subject to the provisions of Paragraph 8 hereof:

              (a)   Designate U.S. Stock Transfer Corporation (the "Exchange
Agent") to implement the exchange (subsequent to the Effective Date) of
certificates representing shares of the U.S. Drug Common Stock (the "Old
Certificates") for certificates representing shares of the USAT Common Stock
(the "New Certificates");

              (b)   engage the Exchange Agent for a period of the lesser of (i) 
12 consecutive months following the Effective Date and (ii) the date on which
all of the Old Certificates held by the U.S. Drug Minority Stockholders have
been surrendered for the New Certificates; and

              (c)   provide to the Exchange Agent sufficient supplies of New
Certificates so as to enable a holder of an Old Certificate(s) to surrender such
Certificate(s) and receive New Certificate(s).

         6.   CERTIFICATE EXCHANGE.  Subsequent to the Effective Date the 
issuance and distribution of New Certificates in exchange for Old Certificates 
shall be implemented as follows:

              (a)   As promptly after the Effective Date as shall be reasonably 
possible, the Exchange Agent shall be directed to, and shall, notify (the
"Notification") each holder of an Old Certificate of the consummation of the
Merger, the availability of New Certificates and a description of the procedure
to be followed (and documents to be executed and submitted) in connection with
the surrender of the Old Certificate and the issuance of the New Certificate.
Upon compliance by a holder thereof with the requirements for the certificate
surrender and issuance specified in the Notification, the Exchange Agent shall
be directed to, and shall, issue and transmit to such holder New Certificates
(representing that number of shares of the USAT Common Stock to which such
holder shall be entitled as herein provided). Until surrendered and replaced as
aforesaid:

                    (i)   each Old Certificate shall, and be deemed to, 
represent and evidence (for all corporate purposes other than the payment of
dividends and other distributions) that number of

                                                                           E-6
                                       6                        Page      of 103
<PAGE>   199
shares of the USAT Common Stock into which the shares of the U.S. Drug Common
Stock therein referred to are convertible and exchangeable as herein provided
and

                    (ii)   each Old Certificate shall not be transferable on the
books and records of U.S. Drug and/or USAT.

              (b)   From and after the Effective Date any and all dividends
and/or distributions of every kind, nature or description declared and payable
by USAT on, or with respect to, the USAT Common Stock to any holder of an Old
Certificate (collectively "Distributions") shall be paid, retained, invested and
paid over as follows:

                    (i)    Until such time as the Old Certificate is surrendered
for replacement by a New Certificate(s) as herein provided, no Distribution
shall be paid over by USAT and/or the Exchange Agent to such holder on, or with
respect to, the shares of the USAT Common Stock evidenced by such Old
Certificate;

                    (ii)   All Distributions payable on, or with respect to, 
shares of the USAT Common Stock represented by Old Certificates shall be paid
over by USAT to the Exchange Agent and dealt in and with by the Exchange Agent
as follows:

                           (A)   All Distributions in cash shall be deposited by
the Exchange Agent in an interest bearing account (the "Distribution Account")
and retained and disposed of as hereinbelow provided;

                           (B)   Upon surrender by, or on behalf of, a holder of
an Old Certificate for surrender and replacement as hereinabove provided (or
satisfactory proof of loss and an indemnity in favor of, and acceptable to, USAT
and the Exchange Agent), the Exchange Agent shall pay over and/or deliver to
such holder (in addition to the New Certificate(s) to which such holder shall be
entitled) (y) the principal amount of any cash dividends and any property (other
than shares of the USAT Common Stock) previously received by the Exchange Agent
with respect to the shares of the USAT Common Stock evidenced by such Old
Certificate and (z) a certificate representing any shares of the USAT Common
Stock forming part of any Distribution made prior to the date of any such
surrender;

                           (C)   Any and all interest earned and/or credited on,
or with respect to, Distributions shall be applied by the Exchange Agent to the
payment of its fees and disbursements and the remainder, if any, paid over to
USAT upon the termination of the engagement of the Exchange Agent.

                                                                           E-7
                                       7                        Page      of 103
<PAGE>   200
              (c)   From and after the Effective Date the sole rights of the
holders of Old Certificates (except as otherwise provided by law or Section 4(a)
hereof) shall be those to which they are entitled as owners of the USAT Common
Stock into which the shares of the U.S. Drug Common Stock evidenced by such Old
Certificates shall have been converted as herein provided.

              (d)   A holder of a Warrant shall, after the Effective Date, have 
no obligation to exchange the holder's certificate evidencing the Warrant for a
new certificate evidencing the Merger Warrant. Whenever thereafter a holder
wishes to exercise his, her or its Warrant, the holder shall present the
Warrant, with the exercise form duly executed and with payment of the new
exercise price per share determined in accordance with Section 4(b) hereof, to
USAT and not to U.S. Drug or Acquisition Corp. USAT shall then cause the
Exchange Agent as the transfer agent for the USAT Common Stock to issue the
shares of the USAT Common Stock as to which the Warrant is exercised. To the
extent that the Warrant is not exercised for all of the shares of the USAT
Common Stock subject thereto, USAT will issue a new certificate evidencing a
Merger Warrant for the balance.

         7.   TRANSFERS.  If the holder of any Old Certificate desires that the 
New Certificate to be issued in replacement therefor (as hereinabove provided)
is to be issued in a name other than that on the Old Certificate which it
replaces, any such issuance shall be subject to and conditioned upon:

              (a)   Delivery to the Exchange Agent of the Old Certificate duly
endorsed in blank or accompanied by a duly executed stock assignment power and
otherwise in form for transfer acceptable to the Exchange Agent; and

              (b)   Payment to USAT or the Exchange Agent of any and all 
transfer and/or other taxes payable, in the opinion of the Exchange Agent, by
reason of the issuance and/or transfer of such New Certificate and/or the shares
of the USAT Common Stock evidenced thereby.

         8.   TERMINATION OF EXCHANGE AGENT. Upon the termination of the 
Exchange Agent's engagement as hereinabove provided, the Exchange Agent shall
deliver to USAT the then balance of the Distribution Account and, upon such
delivery, the Exchange Agent shall have no further duties or obligations as
exchange agent to USAT, Acquisition, U.S. Drug or their respective stockholders.
Thereafter, the duties to be performed by the Exchange Agent as described in
Sections 6 and 7 hereof shall be performed by USAT in lieu of, and instead of,
the Exchange Agent. All blank stock certificates evidencing the USAT Common
Stock shall be retained by the Exchange Agent for utilization by it in the
performance of

                                                                           E-8
                                       8                        Page      of 103
<PAGE>   201
its duties as transfer agent for, and with respect to, the USAT Common Stock.

         9.   SPECIAL PAYMENT.  If U.S. Drug or, subsequent to the Effective 
Date, Acquisition Corp. executes a definitive agreement (the "Marketing
Agreement") with an unaffiliated corporation to act as a marketing partner (the
"Partner") with respect to its drug testing products and if the Partner makes a
cash payment or payments to U.S. Drug, Acquisition Corp. or USAT upon the
execution of the Marketing Agreement (the "Special Payment"), then:

              (a)   USAT will calculate the percentage (to the nearest tenth)
that the outstanding shares of the Minority U.S. Drug Common Stock on the
Effective Date constitute of the outstanding shares of the U.S. Drug Common
Stock on the Effective Date (the "Percentage") and (i) if the Marketing
Agreement is entered into on or prior to the 180th day following the Effective
Date, USAT or, if U.S. Drug or Acquisition Corp. is the recipient of the Special
Payment, Acquisition Corp. shall pay to each of the former U.S. Drug Minority
Stockholders his, her or its pro rata share of one third of the Percentage of
the Special Payment; (ii) if the Marketing Agreement is entered into during the
period after the 180th day following the Effective Date and on or prior to the
first anniversary of the Effective Date, USAT or, if Acquisition Corp. is the
recipient of the Special Payment, Acquisition Corp. shall pay to each of the
former U.S. Drug Minority Stockholders his, her or its pro rata share of one
sixth of the Percentage of the Special Payment; and (iii) if the Marketing
Agreement is entered into after the first anniversary of the Effective Date, the
former U.S. Drug Minority Stockholders shall receive none of the Special
Payment.

              (b)   If a cash payment is received from the Partner after
execution, but on or prior to the first anniversary of the Effective Date, and
if such payment is not based on sales effected by the Partner or some similar
criteria, USAT or Acquisition Corp. will treat any such payment or payments as a
Special Payment as if received on the execution of the Marketing Agreement.

              (c)   A loan or an equity investment made by the Partner shall not
be deemed to be part of the Special Payment.

              (d)   A transferee of the shares of the USAT Common Stock
received as a result of the Merger shall not be eligible to receive a
proportionate share of the Special Payment and USAT or Acquisition Corp. shall
make such payments only to the U.S. Drug Minority Stockholders as reflected on
the stock books of U.S. Drug on the Effective Date or, in the event of the death
of the U.S. Drug Minority Stockholder, his or her heirs or legal
representatives, in the case of the dissolution of a partnership,

                                                                           E-9
                                       9                        Page      of 103
<PAGE>   202
to its partners or, in the case of a corporation, to its successor by merger or
other operation of law.

         10.   THE CLOSING. The closing of the transactions contemplated by this
Agreement shall take place on such date, at such place and at such time within
five business days after the satisfaction or waiver of the last of the
conditions set forth in Sections 18 and 19 hereof as shall be designated by
USAT. The closing of such transactions shall be referred to herein as the
"Closing;" the date of the Closing shall be referred to herein as the "Closing
Date"; and the Closing Date may be the same as the Effective Date.

         11.   THE EFFECTIVE DATE. Subject to the satisfaction and/or waiver of
the conditions herein described, the Merger shall become effective as at the
close of business on the date specified in the Certificate of Merger to be filed
in the manner required by the GCL or, if none, on the date of filing (the
"Effective Date"). Upon the receipt by U.S. Drug of consents from the holders of
more than 50% of the outstanding shares of the Minority U.S. Drug Common Stock
and of a consent from USAT to the Merger, U.S. Drug and Acquisition Corp. shall
cause to be filed the Certificate of Merger in the manner required by the GCL.
Subject to the provisions of Section 20 hereof, such filing shall be made on, or
as soon as practicable after, the Closing Date; and the parties hereto shall
thereafter execute, acknowledge, deliver and/or record such other and further
instruments, documents or certificates and/or take and perform such other and
further actions as may be required to effect and/or implement the Merger. If the
Merger is consummated, USAT will take such actions as are necessary to
deregister the U.S. Drug Common Stock pursuant to Section 12(b) of the Exchange
Act and to delist the U.S. Drug Common Stock from the Pacific Stock Exchange.
The Certificate of Merger shall provide for the change of name of Acquisition
Corp. to "U.S. Drug Testing, Inc."

         12.   THE REGISTRATION STATEMENT AND CONSENT SOLICITATION STATEMENT. In
connection with the preparation, utilization and/or distribution of the Consent
Solicitation Statement- Prospectus to be issued and distributed to the U.S. Drug
Minority Stockholders in connection with the Merger and the preparation and
utilization of the Registration Statement of which the Consent Solicitation
Statement/Prospectus constitutes Part I thereof, the parties shall follow the
procedures as provided in this Section 12.

               (a)   The parties hereto shall cooperate in the preparation
thereof consistent with the applicable requirements of the GCL, the Securities
Act and the Exchange Act and the rules and regulations promulgated under the
Securities Act and the Exchange Act by the SEC; and, without limiting the
generality of

                                                                           E-10
                                      10                        Page      of 103
<PAGE>   203
the foregoing, each of USAT and U.S. Drug shall promptly supply to the other any
and all information and material (relating to itself and/or the subject
transaction) as may be requested or required in connection with the preparation
and filing of the Registration Statement, including, without limitation, all
information concerning their respective officers, directors and principal
stockholders that is reasonably requested for inclusion in the Consent
Solicitation Statement/Prospectus; and each shall take and perform such other
and further acts and actions as shall be necessary or appropriate to cause the
prompt preparation, completion, filing, review, finalization and clearance of
the Registration Statement.

              (b)   Subject to the Registration Statement being declared
effective by the SEC, the Consent Solicitation Statement/Prospectus and any
other communication required by the Exchange Act or the rules and regulations
promulgated thereunder or reasonably requested by USAT shall be mailed by U.S.
Drug or its transfer agent to the U.S. Drug Minority Stockholders as soon after
such effective date as is reasonably possible. Subsequent thereto U.S. Drug
shall transmit to the U.S. Drug Minority Stockholders such amended and/or
supplemental consent solicitation materials as may be necessary, in light of
subsequent developments or otherwise, to render the Consent Solicitation
Statement/Prospectus, as so amended or supplemented, not false or misleading
with respect to any material fact and so as not to omit to state any information
necessary to make the statements made, within the context made, not misleading.
Prior to the Effective Date (or earlier termination of this Agreement) neither
party hereto shall distribute any material (other than the Consent Solicitation
Statement/Prospectus as herein provided) which might constitute, or be deemed to
constitute, a "prospectus" relating to the Merger within the meaning of the
Securities Act without the prior written consent of all of the parties hereto in
each instance.

              (c)   U.S. Drug hereby authorizes the utilization by USAT in the
Registration Statement or in any filing with a state securities administrator of
all information concerning U.S. Drug either provided to USAT by U.S. Drug in
connection with or contained in the Consent Solicitation Statement/Prospectus
and/or contained in any filings heretofore made by U.S. Drug pursuant to the
Securities Act and/or the Exchange Act. U.S. Drug shall promptly advise USAT if
at any time any of such information or material is or becomes incorrect,
inaccurate or incomplete in any material respect and, in connection therewith,
U.S. Drug shall provide USAT with such information and material as shall be
needed to correct any such inaccuracy or omission. USAT shall promptly advise
U.S. Drug if at any time any of the information or material contained in the
Registration Statement and supplied by USAT is or becomes incorrect, inaccurate
or incomplete in any

                                                                           E-11

material respect. USAT shall cause the preparation, review, clearance, approval
and distribution of such amended or supplemented material as shall be necessary
to correct or eliminate any such inaccuracies and/or omissions as provided in
this Section 12(c).

              (d)   Each of USAT and U.S. Drug covenants and warrants to the
other that any and all information and/or material supplied by it to the other
and/or in connection with the Registration Statement and/or the within
transactions (i) will, at the time made and at each Relevant Date (as
hereinafter defined), be true and correct in all material respects; (ii) will
comply in all material respects with the requirements of the Securities Act and
the Exchange Act and the rules and regulations promulgated thereunder by the
SEC; and (iii) will not contain any statement which, at the time, and at each
Relevant Date and in light of the circumstances under which it is made, is false
or misleading with respect to any material fact, or which omits to state any
material fact necessary in order to make the statements therein made not false
or misleading. For the purposes of this Agreement, the term "Relevant Date"
shall be and mean each of (x) the effective date of the Registration Statement,
(y) the mailing date of the Consent Solicitation Statement/Prospectus and (z)
the Effective Date. Each of USAT and U.S. Drug specifically agrees to indemnify
and hold harmless the other (and their respective officers, directors,
employees, agents and representatives) from and against any and all costs,
expenses, losses, demands, claims and liabilities of every kind, nature and
description (including reasonable attorneys' fees) arising out of, or relating
to any breach or anticipatory breach by it of its duties and obligations
pursuant to this Section 12(d) hereof.

              (e)   USAT does hereby agree to indemnify and hold harmless U.S.
Drug and each of its directors and officers, and each person, if any, other than
USAT who controls U.S. Drug within the meaning of Section 15 of the Securities
Act, from and against any and all losses, claims, damages, expenses or
liabilities, joint or several (including, without limitation, reasonable
attorneys' fees as herein provided), to which they or any of them may become
subject under the Securities Act, any other statute, common law or otherwise
and, except as provided below, shall reimburse U.S. Drug and each such director,
officer or controlling person for any legal or other expenses reasonably
incurred by them or any of them in connection with investigating or defending
any actions and/or claims, whether or not resulting in any liability, insofar as
such losses, claims, damages, expenses, liabilities or actions result from a
breach or alleged breach of the representations and warranties contained in
Sections 14 or 15 hereof or are based upon any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
the Consent Solicitation

                                                                           E-12

Statement/Prospectus or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only insofar as any
such untrue statement or omission or alleged untrue statement or omission is
with respect to the description of USAT or as to the terms of its offer.
Promptly after receipt by a party to be indemnified pursuant to this Section 
12(e) (the "Indemnitee") of notice of the commencement of any action in respect
of which indemnity may be sought against USAT hereunder, the Indemnitee will
promptly notify USAT in writing of the commencement thereof and USAT shall,
subject to the provisions stated below, assume the defense of the action
(including the employment of counsel, who shall be counsel reasonable
satisfactory to U.S. Drug), and shall make payment of expenses (including
attorneys' fees as herein provided) insofar as such action shall relate to any
alleged liability in respect of which indemnity may be sought against USAT. The
Indemnitee or Indemnitees shall have the right to employ separate counsel in any
such action and to participate in the defense thereof, but the fees and expenses
of such separate counsel shall not be at the expense of USAT unless the
employment of such separate counsel has been specifically authorized by USAT or
there is a conflict of interest which under the canon of ethics requires the
employment of separate counsel. USAT shall not be liable to any Indemnitee for
any settlement of any action effected without USAT's consent. Notwithstanding
any provision of this Agreement to the contrary, the obligations of USAT
hereunder shall survive the consummation of the transactions contemplated by
this Agreement.

         13.   U.S. DRUG REPRESENTATIONS AND WARRANTIES.  In order to induce 
USAT and Acquisition to execute and perform this Agreement, U.S. Drug does
hereby represent, warrant, covenant and agree (which representations,
warranties, covenants and agreements shall be, and be deemed to be, continuing
and survive the execution and delivery of this Agreement, the Closing and the
Effective Date) as follows:

               (a)   U.S. Drug is a corporation duly organized, validly existing

contemplated and the compliance by U.S. Drug with the terms of this Agreement
have been duly authorized by U.S. Drug; (iii) this Agreement is the valid and
binding obligation of U.S. Drug, enforceable in accordance with its terms,
subject, as to enforcement of remedies, to applicable bankruptcy, insolvency,

generally and the discretion of courts in granting equitable remedies; (iv) the
execution, delivery and performance of this Agreement by U.S. Drug and the
consummation by U.S. Drug of the transactions herein contemplated do not, and
will not, with or without the giving of notice or the lapse of time, or both,
(A) result in any violation of the Certificate of Incorporation or By-Laws of
U.S. Drug or (B) result in a breach of, or a conflict with, any of the terms or
provisions of, or constitute a default under, or result in the modification or
termination of, or result in the creation or imposition of any lien, security
interest, charge or encumbrance upon any of the properties or assets of U.S.
Drug pursuant to, any indenture, mortgage, note, contract, commitment or other
agreement or instrument to which U.S. Drug is a party or by which it is, or any
of its respective properties or assets are, or may be, bound or affected.

         14.   USAT REPRESENTATIONS AND WARRANTIES. In order to induce U.S. Drug
to execute and perform this Agreement, USAT does hereby represent, warrant,
covenant and agree (which representations, warranties, covenants and agreements
shall be, and be deemed to be, continuing and survive the execution and delivery
of this Agreement, the Closing and the Effective Date) as follows:

               (a)   USAT is a corporation duly organized, validly existing and
in standing under the laws of the State of Delaware, with full power and
authority, corporate and otherwise, and with all licenses, permits,
certifications, registrations, approvals, consents and franchises necessary to
own or lease and operate its properties and to conduct its business as presently
being conducted. USAT is duly qualified to do business as a foreign corporation,
and is in good standing, in all jurisdictions, if any, wherein such
qualification is necessary and where failure so to qualify would have a material
adverse effect on the business, properties or financial conditions of USAT. USAT
has no subsidiaries other than as set forth on Exhibit "B" annexed hereto and
made a part hereof (the "Subsidiaries"). USAT owns and has and marketable title
in and to 100% of the issued and outstanding capital stock (of all classes) of
each of the Subsidiaries, free and clear of all liens, security interests,
claims and encumbrances and rights and options of others, except as set forth on
Exhibit "B".

                                                                           E-14
                                      14                        Page      of 103
<PAGE>   207
              (b)   Each of the Subsidiaries (other than U.S. Drug as to which
USAT makes no representation) is a corporation duly organized, validly existing
and in good standing under the laws of the state of its incorporation, with full
power and authority, corporate and otherwise, and with all licenses, permits,
certifications, registrations, approvals, consents and franchises necessary to
own or lease and operate its properties and to conduct its business as presently
being conducted. Each such Subsidiary is duly qualified to do business as a
foreign corporation, and is in good standing, in all jurisdictions, if any,
wherein such qualification is necessary and where failure so to qualify would
have a material adverse effect on the business, properties or finances of such
Subsidiary.

              (c)   (i) USAT has the full power and authority, corporate and
otherwise, to execute, deliver and perform this Agreement and to consummate the
transactions contemplated hereby; (ii) the execution, delivery and performance
of this Agreement, the consummation by USAT of the transactions herein
contemplated and the compliance by USAT with the terms of this Agreement have
been duly authorized by USAT; (iii) this Agreement is the valid and binding
obligation of USAT, enforceable in accordance with its terms, subject, as to
enforcement of remedies, to applicable bankruptcy, insolvency, reorganization,
moratorium and other laws affecting the rights of creditors generally and the
discretion of courts in granting equitable remedies; (iv) the execution,
delivery and performance of this Agreement by USAT and the consummation by USAT
of the transactions herein contemplated do not, and will not, with or without
the giving of notice or the lapse of time, or both, (A) result in any violation
of the Certificate of Incorporation or By-Laws of USAT, (B) result in a breach
of, or a conflict with, any of the terms or provisions of, or constitute a
default under, or result in the modification or termination of, or result in the
creation or imposition of any lien, security interest, charge or encumbrance
upon any of the properties or assets of USAT pursuant to, any indenture,
mortgage, note, contract, commitment or other agreement or instrument to which
USAT is a party or by which it is, or any of its respective properties or assets
are, or may be, bound or affected; (C) to the best knowledge of USAT, after due
investigation, violate any existing applicable law, rule, regulation, judgment,
order or decree of any governmental agency or court, domestic or foreign, having
jurisdiction over USAT and/or any of the Subsidiaries (other than U.S. Drug as
to which USAT makes no representation), or any of their respective properties or
businesses; or (D) have any effect on any license, permit, certification,
registration, approval, consent or other authorization necessary for USAT and/or
any of the Subsidiaries (other than U.S. Drug as to which USAT makes no
representation) to own or lease and operate any of its respective properties and
to conduct its businesses or the ability of USAT and/or any of

                                                                           E-15
                                      15                        Page      of 103
<PAGE>   208
the Subsidiaries (other than U.S. Drug as to which USAT makes no representation)
to make use thereof. No consent, approval, authorization or order of any court,
governmental agency, authority or body (other than as required pursuant to the
Securities Act, the Exchange Act and/or state securities or "take over" statutes
and the rules and regulations promulgated under any of the foregoing and/or any
party to an agreement to which USAT is a party and/or by which it is bound) is
required in connection with the execution, delivery and performance of this
Agreement and/or the consummation by USAT of the transactions contemplated by
this Agreement.

              (d)   Neither USAT nor any of the Subsidiaries (other than U.S.
Drug as to which USAT makes no representation) is in violation of, or in default
under, (i) any term or provision of its Certificate of Incorporation or By-Laws;
(ii) any material term or provision of any financial covenant of any indenture,
mortgage, contract, commitment or other agreement or instrument to which it is a
party or by which it or any or its properties or business is, or may be, bound
or affected; or (iii) any existing applicable law, rule, regulation, judgment,
order or decree of any governmental agency or court, domestic or foreign, having
jurisdiction over it or any of its properties or business, including, without
limitation, all reporting obligations pursuant to the Exchange Act and the rules
and regulations promulgated thereunder. USAT and each Subsidiary (other than
U.S. Drug as to which USAT makes no representation) owns, possesses or has
obtained all governmental and other licenses, permits, certifications,
registrations, approvals or consents and other authorizations necessary to own
or lease, as the case may be, and to operate its properties and to conduct its
business or operations as presently conducted and all such governmental and
other licenses, permits, certifications, registrations, approvals, consents and
other authorizations are outstanding and in good standing and there are no
proceedings pending or, to the best of its knowledge, threatened or any basis
therefor existing, seeking to cancel, terminate or limit such licenses, permits,
certifications, registrations, approvals or consents or authorizations.

              (e)   Prior to the date hereof USAT has delivered to U.S. Drug
copies of the audited consolidated financial statements (the "USAT Audited
Financial Statements") and unaudited interim financial statements (the "USAT
Interim Financial Statements") described on Exhibit "C" annexed hereto and made
a part hereof (collectively the "USAT Financial Statements). The USAT Audited
Financial Statements fairly present the financial position of USAT and the
Subsidiaries as of the respective dates thereof and the results of operations,
and the changes in financial position of USAT and the Subsidiaries, for each of
the periods covered thereby. The USAT Audited Financial Statements have been

                                                                           E-16
                                      16                        Page      of 103
<PAGE>   209
prepared in conformity with generally accepted accounting principles, applied on
a consistent basis throughout the entire periods involved. The USAT Unaudited
Financial Statements have been prepared in accordance with generally accepted
accounting principles for interim financial information and the instructions to
Form 10-Q and Item 310 of Regulation S-K of the SEC. Accordingly, the financial
statements may not include all of the information and footnotes required by
generally accepted accounting principles. In the opinion of USAT's management,
all adjustments (consisting of normal recurring adjustments) considered
necessary for a fair presentation have been included. As of the date of any
balance sheet forming a part of the USAT Financial Statements and, except as and
to the extent reflected or reserved against therein, neither USAT nor any of the
Subsidiaries (other than U.S. Drug as to which USAT makes no representation) had
any material liabilities, debts, obligations or claims (absolute or contingent)
asserted against it or them and/or which should have been reflected in a balance
sheet or the notes thereto; and all assets reflected thereon are properly
reported and present fairly the value of the assets therein stated in accordance
with generally accepted accounting principles.

              (f)   The financial and other books and records of USAT and each
of the Subsidiaries (other than U.S. Drug as to which USAT makes no
representation) are in all material respects true, complete and correct and
have, at all times, been maintained in accordance with good business and
accounting practices.

              (g)   USAT and the Subsidiaries (other than U.S. Drug as to which 
USAT makes no representation) own and have good and marketable title in and to
all of their respective assets, properties and interests in properties (both
real and personal) which are reflected in the latest balance sheet included in
the USAT Financial Statements and/or are utilized in connection with the
operation of the business of USAT and such Subsidiaries as presently constituted
and/or acquired after that date (except to the extent any of the same were
disposed of since such date in the ordinary course of business), in all cases
free and clear of all liens, security interests, claims and encumbrances of
every kind, nature and description and rights and options of others except as
expressly set forth in such balance sheet.

              (h)   Except as is set forth on Exhibit "D" hereto, USAT and the
Subsidiaries (other than U.S. Drug as to which USAT makes no representation) own
all trademarks, service marks, tradenames, copyrights, similar rights and their
registrations, trade secrets, methods, practices, systems, ideas, know how and
confidential materials used or proposed to be used in the conduct of their
respective businesses as conducted as of the date hereof (collectively the
"Intangibles") free and clear of all liens,

                                                                           E-17

<PAGE>   210
security interests, claims and encumbrances and rights and options of third
parties (including, without limitation, former or current officers, directors,
stockholders, employees and agents); neither USAT nor any such Subsidiary has
licensed or leased any of the Intangibles and/or any interest therein to any
person and/or entity except a Subsidiary; neither USAT nor any such Subsidiary
has infringed, nor is infringing, upon the rights of others with respect to the
Intangibles; neither USAT nor any such Subsidiary has received any notice of
conflict with the asserted rights of others with respect to the Intangibles
which could, singly or in the aggregate, materially adversely affect its
business as currently conducted or prospects, financial condition or results of
operations and USAT knows of no basis therefor; and, to the best of the
knowledge of USAT, no others have infringed upon the Intangibles.

              (i)   Except as and to the extent reflected or reserved against in
the USAT Financial Statements and/or as set forth on Exhibit "E" annexed hereto
and made a part hereof, neither USAT nor any of the Subsidiaries (other than
U.S. Drug as to which USAT makes no representation) had, as at the respective
date of such USAT Financial Statements, any material liabilities, debts,
obligations or claims asserted against it, whether accrued, absolute, contingent
or otherwise, and whether due or to become due, including, but not limited to,
liabilities on account of due and unpaid taxes, other governmental charges or
lawsuits.

              (j)   Since the date of the most recent balance sheet included in 
the USAT Financial Statements, neither USAT nor any Subsidiary (other than U.S.
Drug as to which USAT makes no representation) has, except as set forth on
Exhibit "F" annexed hereto and made a part hereof, (i) incurred any obligation
or liability (absolute or contingent, secured or unsecured) except obligations
and liabilities incurred in the ordinary course of the operation of its business
as carried on at and prior to such date; (ii) canceled, without payment in full,
any notes, loans or other obligations receivable or other debts or claims held
by it other than in the ordinary course of business; (iii) sold, assigned,
transferred, abandoned, mortgaged, pledged or subjected to lien or security
interest any of its material properties, tangible or intangible, or rights under
any contract, permit, license, franchise or other agreement other than sales or
other dispositions of goods or services in the ordinary course of business at
customary prices; (iv) entered into any line of business other than that
conducted by it on such date or entered into any transaction not in the ordinary
course of its business; (v) conducted any line of business in any manner except
by transactions customary in the operation of its material business as conducted
on such date; or (vi) declared, made or paid, or set aside for payment, any cash
or non-cash dividends or other distribution on any shares of its capital stock.

                                                                           E-18

<PAGE>   211
              (k)   Except as set forth on Exhibit "G" annexed hereto and made a
part hereof, neither USAT nor any of the Subsidiaries (other than U.S. Drug as
to which USAT makes no representation) is in default, in any material respect,
under the terms of any outstanding agreement which is material to the business,
operations, properties, assets or condition of USAT and/or the Subsidiaries
(other than U.S. Drug as to which USAT makes no representation); and there
exists no event of default or event which, with notice and/or the passage of
time, or both, would constitute any such default.

              (l)   Except as reported in the USAT Financial Statements and/or
as set forth on Exhibit "H" hereto and made a part hereof, there are no claims,
actions, suits, proceedings, arbitrations, investigations or inquiries before
any court or governmental agency, court or tribunal, domestic, or foreign, or
before any private arbitration tribunal, pending or, to the best of the
knowledge of USAT, threatened against USAT and/or any Subsidiary (other than
U.S. Drug as to which USAT makes no representation) or involving their
respective properties or businesses which, if determined adversely to USAT or
such Subsidiary, would, individually or in the aggregate, result in a material
adverse change in the financial position, stockholders' equity, results of
operations, properties, business, management or affairs of USAT or such
Subsidiary, or which question the validity of this Agreement or of any action
taken, or to be taken, by USAT pursuant to, or in connection with, this
Agreement; nor, to the best of the knowledge of USAT, is there any basis for any
such claim, action, suit, proceeding, arbitration, investigation or inquiry to
be made by any person and/or entity, including, without limitation, any
customer, supplier, lender, stockholder, former or current employee, agent or
landlord. There are no outstanding orders, judgments or decrees of any court,
governmental agency or other tribunal specifically naming USAT and/or any
Subsidiary (other than U.S. Drug as to which USAT makes no representation)
and/or enjoining USAT and/or any such Subsidiary from taking, or requiring USAT
and/or any such Subsidiary to take, any action and/or by which USAT and/or any
such Subsidiary is, and/or their respective properties or businesses are, bound
or subject.

              (m)   USAT and each of the Subsidiaries (other than U.S. Drug as 
to which USAT makes no representation) has filed all federal, state, municipal
and local tax returns (whether relating to income, sales, franchise,
withholding, real or personal property or otherwise) required to be filed under
the laws of the United States and all applicable states and has paid in full all
taxes which are due pursuant to such returns or claimed to be due by any taxing
authority or otherwise due and owing. No penalties or other charges are, or will
become, due with respect to the late filing of any such return. To the best of
the knowledge of

                                                                           E-19
                                       19                       Page      of 103
<PAGE>   212
USAT, after due investigation, each such tax return heretofore filed by USAT and
each of such Subsidiaries correctly and accurately reflects the amount of its
tax liability thereunder. USAT has withheld, collected and paid all other
levies, assessments, license fees and taxes to the extent required and, with
respect to payments, to the extent that the same have become due and payable.

              (n)   The authorized and outstanding capitalization of USAT is as 
set forth on Exhibit "I" annexed hereto and made a part hereof; as of the date
hereof and the Closing Date, there shall not be authorized and/or issued and
outstanding any shares of capital stock of USAT and/or rights to purchase shares
of capital stock of USAT except as set forth on Exhibit "I" or upon the exercise
of outstanding warrants or options or the conversion of outstanding shares of
preferred stock. The issued and outstanding shares of the USAT Common Stock and
outstanding options, warrants and other similar rights to purchase the USAT
Common Stock have been duly authorized and validly issued. All such outstanding
shares of the USAT Common Stock are fully paid and nonassessable. All such
outstanding options, warrants and similar rights to purchase the USAT Common
Stock constitute the valid and binding obligations of USAT, enforceable in
accordance with their respective terms, subject, as to enforcement of remedies,
to applicable bankruptcy, insolvency, reorganization, moratorium and other laws
affecting the rights of creditors generally and the discretion of courts in
granting equitable remedies. There are no preemptive rights. USAT has no reason
to believe that any holder of such outstanding shares of the USAT Common Stock
is subject to personal liability solely by reason of being such a holder. The
offers and sales of such outstanding shares of the USAT Common Stock and
outstanding options, warrants and similar rights to purchase the USAT Common
Stock were, at all relevant times, either registered under the applicable
provisions of the Securities Act and the applicable state securities laws or
exempt from such registration or prospectus filing requirements pursuant to an
exemption for which USAT and/or such offering or sale fully qualified, or any
claim arising out of, or relating to, any such offering and/or sale are barred
by the statute of limitations. The authorized shares of the USAT Common Stock
and outstanding options, warrants and similar rights to purchase the USAT Common
Stock conform to the description thereof contained in the current filings by
USAT pursuant to the Exchange Act. No dividends or other distributions of the
assets of USAT have or will be declared and/or paid prior to the Closing Date on
or with respect to the USAT Common Stock.

              (o)   Except as is set forth on Exhibit "J" hereto, since the date
of the most recent balance sheet included in the USAT Financial Statements,
there has not been, with respect to USAT and/or the Subsidiaries (other than

The Board of Directors
U.S. Drug Testing, Inc.
10410 Trademark Street
Rancho Cucamonga, CA 91730


Members of the Board:

     You have requested our opinion as investment bankers as to the fairness to
the minority stockholders of U.S. Drug Testing, Inc. ("U.S.  Drug"), from a
financial point of view, of the exchange ratio to be offered to the minority
stockholders of U.S. Drug under the Agreement and Plan of Merger dated as of
April 23, 1996 (the "Merger Agreement") among U.S. Drug, U.S. Alcohol Testing
of America, Inc. ("USAT") and U.S.  Drug Acquisition Corp., a wholly owned
subsidiary of USAT ("Acquisition Corp."), pursuant to which U.S. Drug will be
merged with and into Acquisition Corp. (the "Proposed Merger") with the result
that U.S. Drug will become a wholly-owned subsidiary of USAT.  As more
specifically set forth in the Merger Agreement, holders of the 1,721,900 issued
and outstanding shares of U.S. Drug's common stock, par value $.001 per share,
not owned by USAT (the "Minority U.S. Drug Common Stock"), will receive ___
shares (the "Exchange Ratio") of USAT's common stock, par value $.01 per share
(the "USAT Common Stock"), for each share of the Minority U.S. Drug Common
Stock.  The holders of the Minority U.S. Drug Common Stock will thus receive an
aggregate of _____________ shares of the USAT Common Stock, subject to
adjustment for fractional shares.  Cash will be paid in the Proposed Merger in
lieu of fractional shares of the USAT Common Stock.  The terms and conditions
of the Proposed Merger are more fully set forth in the Merger Agreement.

     In arriving at our opinion, we have reviewed and considered, among other
things: (i) the Merger Agreement; (ii) U.S. Drug's and USAT's Annual Reports on
Form 10-K for the three fiscal years ended March 31, 1996, 1995 and 1994 and
Quarterly Reports on Form 10-Q for the quarterly periods ended June 30, 1995,
September 30, 1995 and December 31, 1995; (iii) certain information, including
financial forecasts, relating to the businesses, earnings and prospects of U.S.
Drug and USAT, furnished to us by senior
<PAGE>   227
The Board of Directors
U.S. Drug Testing, Inc.

Page 2




management; (iv) the historical market prices and trading activity for U.S.
Drug and USAT shares; and (v) publicly available information concerning certain
other companies and transactions we considered relevant to our analysis.  In
addition, we have held discussions with the managements of U.S. Drug and USAT
for the purpose of reviewing the historical and current operations of such
companies and the business prospects for each.

     In conducting our analysis and in arriving at our opinion, we have, with
your consent, relied upon and assumed the accuracy and completeness of the
financial and other information that was publicly available or provided to us
and we have not undertaken to independently verify the same.  We have not
prepared or obtained any independent evaluation or appraisal of U.S. Drug's or
USAT's assets or liabilities.  We have assumed and relied upon the senior
management of U.S. Drug and USAT as to the reasonableness and achievability of
the financial and operating forecasts furnished by management (and the
assumptions and bases therefor).  Our opinion is necessarily based on economic,
market and other conditions as in effect on, and the information made available
to us as of, the date hereof.  We have been retained by the Board of Directors
of U.S. Drug to act as financial advisor to U.S. Drug only with respect to this
fairness opinion.  We have not in the past three years previously acted on
behalf of U.S. Drug or USAT.  We are currently separately engaged to render a
fairness opinion to the Board of Directors of Good Ideas Enterprises, Inc.
("Good Ideas"), an affiliate of U.S. Drug and USAT, for which we will receive a
customary fee.  In addition, in the ordinary course of our securities business,
we may actively trade equity securities of U.S. Drug and/or USAT and/or Good
Ideas for our own account and the accounts of customers, and we, therefore, may
from time to time hold a long or short position in such securities.  Our
opinion is directed to the Board of Directors of U.S. Drug and does not
constitute a recommendation to any stockholder of U.S. Drug as to how such a
stockholder should consent on any matter submitted for U.S. Drug stockholder
consent in connection with the Proposed Merger.

         We reviewed the Special Payment (as defined), but, because we
considered this offer to be entirely speculative, we did not assign any value
to the Special Payment in reaching our conclusion as set forth in the next
paragraph.

     On the basis of and subject to the foregoing, as of the date hereof, we
are of the opinion that the Exchange Ratio in the
<PAGE>   228

Proposed Merger is fair to the minority stockholders of U.S. Drug from a
financial point of view.

                                        Very truly yours,



                                        Whale Securities Co., L.P.

No person has been authorized to give any information or to make any
representations in connection with this offering other than those contained in
this Consent Solicitation Statement/Prospectus and, if given or made, such
information or representations must not be relied upon as having been
authorized by USAT or U.S. Drug.  This Prospectus does not constitute an offer
to sell or a solicitation of an offer to buy the securities offered hereby to
any person in any state or other jurisdiction in which such offer or
solicitation would be unlawful.  Neither the delivery of this Prospectus nor
any sale made hereunder shall, under any circumstances, create any implication
that the information contained herein is correct as of any time subsequent to
the date hereof.

ITEM 20.          INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Board of Directors of U.S. Alcohol Testing of America, Inc. (the
"Registrant" or "USAT") has authorized indemnification of directors and
officers of the Registrant to the fullest extent permitted by Delaware law.

         Section 145(a) of the General Corporation Law of Delaware (the "GCL")
permits a corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation), by reason of the
fact that he or she is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred in connection with such action, suit or proceeding if he or she acted
in good faith and in a manner he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

         Under Section 145(b) of the GCL, a corporation also may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he or
she is or was a director, officer, employee or agent of the corporation, or is
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if he or she acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
corporation.  However, in such an action by or on behalf of a corporation, no
indemnification may be in respect of any claim, issue or matter as to which the
person is adjudged liable to the corporation unless and only to the extent that
the court determines that, despite the adjudication of liability but in view of
all the circumstances, the person is fairly and





                                      II-1
<PAGE>   231
reasonably entitled to indemnity for such expenses which the court shall deem
proper.

         In addition, under Section 145(f) of the GCL, the indemnification
provided by Section 145 shall not be deemed exclusive of any other rights to
which those seeking indemnification may be entitled under any by-law,
agreement, vote of stockholders or disinterested directors or otherwise, both
as to action in his official capacity and as to action in another capacity
while holding such office.

arising after the effective date of the Registration Statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
Registration Statement;

                  (iii)  To include any material information with respect to
the plan of distribution not previously disclosed in the Registration Statement
or any material change to such information in the Registration Statement;

         (2)      That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendments shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3)      To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of this offering.
    

         The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

         The Registrant undertakes that every prospectus: (i) that is filed
pursuant to the paragraph immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the Registration Statement and will not be used until
such amendment is effective, and that, for purposes of determining any
liability under the Securities Act, each such





                                     II-11
<PAGE>   241
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

         The undersigned Registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

         The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

July 31, 1996




Board of Directors
U.S. Drug Testing, Inc.
Rancho Cucamonga, CA  91730

Gentlemen:

You have requested our opinion as to the principal federal income tax effects to
the minority stockholders (the "Minority Stockholders") of U.S. Drug Testing,
Inc. ("U.S. Drug") upon consummation of the proposed merger (the "Merger") of
U.S. Drug with and into a wholly-owned subsidiary of U.S. Alcohol Testing of
America, Inc. ("USAT") as more fully described in the combined Consent
Solicitation Statement/Prospectus (the "Prospectus") filed with the Securities
and Exchange Commission on May 6, 1996 relating to the Merger, and as to certain
other matters. All capitalized terms used and not defined herein shall have the
meanings ascribed to them in the Prospectus.

In connection with your request, we have reviewed the following documents: (a)
the Agreement and Plan of Merger (the "Merger Agreement") dated April 23, 1996
by and among U.S. Drug, USAT and U.S. Drug Acquisition Corp. ("Acquisition
Corp."), a wholly-owned subsidiary of USAT; (b) the Prospectus and the exhibits
filed therewith; and (c) such other documents as we have deemed necessary or
appropriate to review in rendering this opinion.

In connection with our rendering of this opinion, USAT has represented to us
that:

         (1)  U.S. Drug and USAT are corporations formed and validly existing 
              under the laws of the State of Delaware.

         (2)  USAT formed Acquisition Corp. as a wholly-owned subsidiary under
              the laws of the State of Delaware to effectuate the Merger.

         (3)  USAT currently owns, and will own immediately prior to the time 
              the Merger
<PAGE>   2
Board of Directors
July 31, 1996
Page 2



              is consummated, approximately 67% of the stock of U.S. Drug.

         (4)  The Merger will be effectuated pursuant to the laws of the State
              of Delaware in the form of a forward triangular merger, i.e., U.S.
              Drug will merge with and into Acquisition Corp., with the Minority
              Stockholders exchanging their stock in U.S. Drug for stock in USAT
              and the Special Payment, and immediately after the Merger USAT
              will continue to own 100% of the shares of Acquisition Corp.

         (5)  The liabilities of U.S. Drug assumed by Acquisition Corp. and the
              liabilities to which the transferred assets of U.S. Drug are
              subject were incurred by U.S. Drug in the ordinary course of its
              business.

         (6)  The value of the Special Payment is too speculative to permit such
              value to be ascertained at the time of the Merger because the
              Special Payment is conditioned on a potential cash payment under a
              marketing agreement with an undetermined third-party which has not
              been executed and which may never be executed. In no event will
              the amount of the Special Payment exceed the value of the USAT
              stock received by the Minority Stockholders in the Merger.

         (7)  To the best knowledge of the management of USAT, there is no plan
              or intention on the part of the Minority Stockholders to sell,
              exchange or otherwise dispose of a number of shares of USAT stock
              received in the transaction that would reduce the Minority
              Stockholders' ownership of USAT stock to a number of shares having
              a value, as of the date of the transaction, of less than 50
              percent of the value of all the formerly outstanding stock of U.S.
              Drug in the hands of the Minority Stockholders as of the same
              date.

         (8)  Acquisition Corp. will acquire at least 90 percent of the fair 
              market value of the net assets and at least 70 percent of the fair
              market value of the gross assets held by U.S. Drug immediately
              prior to the transaction.

         (9)  Following the transaction, Acquisition Corp. will not issue
              additional shares of its stock that would result in USAT owning
              less the 80% of the total combined voting power of all classes of
              Acquisition Corp. stock entitled to vote or less than 80% of the
              total number of shares of all other classes of Acquisition Corp.
              stock.

Board of Directors
July 31, 1996
Page 3



         (10)  USAT has no plan or intention to reacquire any of its stock
               issued in the transaction.

         (11)  USAT has no plan or intention to liquidate Acquisition Corp., to
               merge Acquisition Corp. with and into another corporation, to 
               sell or otherwise dispose of the stock of Acquisition Corp., or 
               to cause Acquisition Corp. to sell or otherwise dispose of any of
               the assets of U.S. Drug acquired in the transaction, except for
               dispositions made in the ordinary course of business.

         (12)  Following the transaction, Acquisition Corp. will continue the 
               historic business of U.S. Drug or use a significant portion of
               U.S. Drug's business assets in a business.

         (13)  USAT, Acquisition Corp., U.S. Drug and the shareholders of U.S.
               Drug will pay their respective expenses, if any, incurred in
               connection with the transaction.

         (14)  No stock of Acquisition Corp. will be issued in the transaction.

         (15)  The fair market value of the assets of U.S. Drug transferred to
               Acquisition Corp. will equal or exceed the sum of liabilities
               assumed by Acquisition Corp., plus the amount of liabilities, if
               any, to which the transferred assets are subject.

         (16)  U.S. Drug is not under the jurisdiction of a court in a Title 11
               or similar case.


Discussion

The Merger will meet the statutory requirements of a tax free reorganization
within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal
Revenue Code of 1986, as amended (the "Code"). The Merger will be effected
pursuant to Delaware law, USAT will "control" Acquisition Corp. within the
meaning of Code Section 368(c) as of the effective date of the Merger and
thereafter, Acquisition Corp. will acquire substantially all the assets of U.S.
Drug pursuant to the Merger, and no stock of Acquiring Corp. will be issued as
part of the Merger.

Conclusion
<PAGE>   4
Board of Directors
July 31, 1996
Page 4



On the basis of our review of the aforementioned documents, the representations
set forth above and on the basis of federal income tax law as currently in
effect, including the Code, existing judicial decisions and administrative
regulations, rulings, procedures and practice, it is our opinion that the Merger
will be treated as a reorganization within the meaning of Code Sections 
368(a)(1)(A) and 368(a)(2)(D) with the following consequences:

         (a)  no gain or loss will be recognized by the Minority Stockholders
              upon the receipt of the USAT Common Stock and the right to receive
              the Special Payment in exchange for the U.S. Drug stock;

         (b)  any cash subsequently received by the Minority Stockholders in
              accordance with the terms of the Special Payment will constitute
              "boot" and will result in such Minority Stockholder recognizing
              gain equal to the lesser of the amount of the cash payment
              received or the gain realized on the overall Merger transaction;

         (c)  the tax basis of the USAT stock received by the Minority
              Stockholders will be the same as the tax basis of the U.S. Drug
              stock surrendered in the Merger, plus any gain realized on the
              Merger transaction, less any cash received;

         (d)  the holding period, for federal income tax purposes, of the USAT
              stock received by the Minority Stockholders will, in the hands of
              such stockholders, include the holding period of the shares of
              U.S. Drug stock exchanged therefor, provided that such stock was
              held as a capital asset in the hands of such Minority Stockholders
              on the effective date of the Merger; and

         (e)  a Minority Stockholder receiving cash in lieu of a fractional
              share will realize a gain for federal income tax purposes to the
              extent of the cash received in excess of the tax basis of the
              fractional share.


In addition, we have reviewed the discussion under the heading "Certain Tax
Consequences" in the Prospectus. In our opinion, such discussion is accurate as
of the date hereof in all material respects insofar as it relates to the federal
income tax aspects of the Merger as they affect U.S. Drug and the Minority
Stockholders. We have not, however, independently verified any of the financial
statements or assumptions set forth in the Prospectus, and, accordingly, our
opinion is qualified to that extent.

We hereby consent to the use of this opinion as an exhibit to the Prospectus and
to the use of our name under the heading "Certain Tax Consequences."

3.       Term.

         3.1     Term.  The term of this Lease is twenty (20) years commencing

is issued (the "Commencement Date") and ending at midnight, twenty (20) years
thereafter, unless sooner terminated pursuant to any provision hereof.

         3.2     Delay in Completion of Improvements.  Landlord will take all
steps reasonably necessary in order to ensure that the Improvements, as that
term is hereinafter defined, are completed no later than

(a) any act or omission of the Tenant or any of its employees, agents or
contractors (including, but not limited to (i) any delays due to changes in or
additions to the Improvements, or (ii) any delays by Tenant in the submission
of plans, drawings, specification, or other information or in approving
drawings or in giving any authorizations or approvals); (b) any delays beyond
control of Landlord including, but not limited to, strikes, lockouts, civil
commotion, warlike conditions, invasion, rebellion, hostility, inclement
weather, inability to obtain material or services and acts of God; or (c) any
delays caused by governmental regulations or controls, Landlord shall not be
subject to any liability therefore, nor shall such failure affect the validity
of the Lese or the obligations of Tenant hereunder, but in such case, Tenant
shall not be obligated to pay rent until possession of the Premises is tendered
to Tenant.

         3.3     Early Possession.  If Tenant occupies the Premises prior to
the Commencement Date, such occupancy shall be subject to all provisions

</TABLE>

                 (b) The term "Lease Year", as used herein, (i) shall mean the
twelve (12) month period beginning with the Commencement Date as defined in
Section 3.1 hereof, and each twelve (12) month period thereafter occurring
during the term of this Lease, and (ii) in the event the Lease expires or
terminates on a date other than the date set forth herein, then the term "Lease
Year" shall also mean the period from the end of the preceding Lease Year to
the date of said expiration or termination of this Lease.  Landlord and Tenant
agree that subsequent to the end of each and every Lease Year the Monthly Rent,
or Adjusted monthly Rent, as herein defined, if applicable, which was payable
for the immediately preceding Lease Year shall be adjusted for payment during
the current Lease Year by an amount equal to the product of (i) the Monthly
Rent or adjusted Monthly Rent, if applicable, for the immediately preceding
Lease Year multiplied by (ii) the difference expressed as a percentage between
the Consumer Price Index, as herein below defined, published for the last month
of the immediately preceding Lease year and the Consumer Price Index for the
corresponding month one year prior thereto (i.e., the percentage change in said
Index over said year); provide, however, that such new Monthly rent shall in no
event be less than the Monthly Rent, or Adjusted Monthly Rent for the preceding
year.  The monthly rental payment so adjusted by the Consumer Price Index shall
become the adjusted monthly rent (the "Adjusted Monthly Rent").  The initial
annual adjustment shall be computed based on the Monthly Rent and the next
annual adjustment shall be computed based on the Adjusted Monthly Rent with
each annual adjustment thereafter based on the Adjusted Monthly Rent for the
immediately proceeding year.  As
<PAGE>   3
soon as practicable after the end of each Lese Year, Landlord shall prepare and
submit to Tenant a statement (the "Statement") reflecting the Adjusted Monthly
Rent which shall be paid commencing with the next monthly installment of Rent
and shall remain in effect until the next annual adjustment is made.  In
addition, within twenty (20) days following receipt of Landlord's Statement,
Tenant shall pay to Landlord a sum equal to the difference between the amount
of monthly rental payments Tenant has paid Landlord since the start of the
current Lease Year, if any, and an amount computed as follows:  1/12th of the
total Adjusted Monthly Rent for the entire current Lease Year multiplied by the
number of months which have fully or partially expired between the first day of
the current lease year and the date of the first payment of the Adjusted
Monthly Rent to be made subsequent to the date of the Statement.

                 Any Statement sent by Landlord to Tenant shall be conclusively
binding upon Tenant unless, within thirty (30) days after such Statement is
sent, Tenant shall send a written notice to Landlord objecting to such
Statement and specifying the respects in which such Statement is claimed to be
incorrect.  If such notice is sent and the parties are unable to revolve the
issues, either party hereto may refer the matter to a reputable independent
firm of certified accountants selected by Landlord, and the decision of said
accountants shall be conclusively binding upon said parties.  The fees and
expenses of the accountants shall be borne by the unsuccessful party unless
both parties are unsuccessful, then said expenses shall be apportioned between
the parties by the accountants based upon the degree of success of each party.

                 The term "Consumer Price Index," as used herein, shall be the
Consumer Price Index for All Urban Consumers based upon the U.S. City Average
(All Items Included, 1982-94 = 100) published by the Bureau of Labor Statistics
of the United States Department of Labor.  If the Consumer Price Index shall
hereafter be converted to a different standard reference base or otherwise
revised, the determination of the percentage increase in the Consumer Price
Index shall be made with the use of such conversion factor, formula or table
for converting the Consumer Price Index as may be published by the Bureau of
Labor Statistics or, if said Bureau shall not publish the same, then with the
use of such conversion factor, formula or table as may be published by Prentice
Hall, Inc., or, failing such publication, by any other nationally recognized
publisher of statistical information.  If the consumer Price Index shall become
unavailable to the public because publication is discontinued, or otherwise,
Landlord will substitute therefor a comparable index based upon changes in the
cost of living or purchasing power of the consumer dollar published by any
other governmental agency, or, if no such index shall be then available, a
comparable index published by a major bank or other financial institution or by
a university or a recognized financial publication, and the substituted index
shall
<PAGE>   4
be deemed the Consumer Price Index for the purposes of this Section.

                 (c) Tenant agrees that any adjustments to the base monthly
Rent and other sums due Landlord from Tenant under the tomboys of this Lease
shall be considered as additional rent from Tenant (the "Additional Rent").  As
used herein the term "Rent" shall include the Monthly Rent, Adjusted Monthly
Rent, Additional Rent and such other payments as are set forth herein.

                 (d)      It is understood and agreed that Tenant's obligation
to pay the Additional Rent shall, for the purposes of the default provision
hereof, entitle Landlord to all remedies provided herein and at law or equity
on account of Tenant's failure to pay rent.

                 (e) In no event shall any adjustments made pursuant to Section
4.1(b) result in the Landlord receiving an amount less than the Monthly Rent or
Adjusted Monthly Rent,if applicable for the immediately preceding Lease Year.

                 (f) Any delay or failure of Landlord in computing or billing
for Additional Rent shall not constitute a waiver or in any way impair the
continuing obligation of the Tenant to pay such Additional Rent.

         4.2     Security Deposit.  Tenant shall deposit with Landlord on the
Commencement Date $8,308.23 as security for Tenant's faithful performance of
Tenant's obligations hereunder (the "Security Deposit").  If Tenant fails to
pay rent or other charges due hereunder, or otherwise defaults with respect to
any provision of  this Lease, Landlord may use, apply or retain all or any
portion of the Security Deposit for the payment of any rent or other charge in
default or for the payment of any sum to which Landlord may become obligated by
reason of Tenant's default, or to compensate Landlord for any loss or damage
which Landlord may suffer thereby.  If Landlord so uses or applies all or any
portion of the Security deposit, Tenant shall within fifteen (15) days after
written demand therefore, deposit cause with Landlord in an amount sufficient
to restore the Security Deposit to the full amount hereinabove stated and
Tenant's failure to do so shall be a material breach of this Lease.  Landlord
shall not be required to keep said deposit separate from its general accounts.
If Tenant performs all of Tenant's obligations hereunder, the Security Deposit,
or so much thereof as has not theretofore been applied by Landlord, shall be
returned without payment of interest or other increment for its use to Tenant
(or, at Landlord's option, to the last assignee, if any, of Tenant's interest
hereunder) at the expiration of the term hereof, and after Tenant has vacated
the Premises.  No trust relationship is created herein between Landlord and
Tenant with respect to the Security Deposit.

5.       Use.

         5.1     Use.  The Premises shall be used by Tenant for offices and for
no other purposes, and Tenant further agrees to use the entire Premises as
herein above provided.  Tenant agrees not to store any material, waste or other
products outside the Premises in any adjoining area.  Tenant further agrees
that it will not store or dispose of hazardous materials in or about the
Premises.  For the purposes of this Lease, "hazardous materials" includes any
hazardous, toxic or dangerous waste, substance or material defined as such in
(or for purposes of) the Comprehensive Environmental Response, Compensation and
Liability Act, any so-called "superfund" of "superlien" law, or any other
federal, state or local statute, law ordinance, code,rule, regulation, consent
agreement or other requirement of any governmental authority regulating,
relating to, or imposing liability or standards of conduct concerning, any
hazardous or toxic or dangerous waste.  Tenant shall defend, indemnify and save
Landlord harmless from all costs and expenses (including consequential damages)
asserted or proven against Landlord by any party as result of Tenant's use,
storage or disposal of hazardous materials (as defined above) on the Premises.
The foregoing indemnity shall be a recourse obligation of Tenant which shall
survive termination or expiration of this Lease.  In the event that any
activity of the Tenant causes an increase in the insurance rate on the building
containing the Premises as a whole, then Tenant shall pay this additional cost
of insurance as assessed by Landlord's insurer, which determination shall be
conclusive and binding upon Tenant.

         5.2     Compliance with Law.  Tenant shall, at Tenant's expense,
comply promptly with all applicable statutes, ordinances, rules, regulations,
orders, permits, covenants and restrictions of record, and requirements in
effect during the term or any part of their term hereof, regulating the use or
condition of the Premises, including but not limited to, environmental matters
and employee health and safety.  Tenant shall not use nor permit the use of the
Premises in any manner that will tend to create waste or a nuisance or, if
there shall be more than one tenant in the building containing the Premises,
shall tend to disturb such tenants.

present or future suitability of the Premises for the conduct of Tenant's
business.

         5.4     Common Areas.  All areas and facilities that Landlord shall
from time to time designate as being for the mutual use of Tenant, its
customers, employees and other tenants,

Premises to the extent that the cost of repair is fifty percent (50%) or more
of the fair market value of the Premises immediately prior to such damage or
destruction.

         8.2     Partial Damage.  If at any time during the term of this Lease
there is damage which falls within the classification of Partial Damage,
Landlord may, at Landlord's option, either (i) repair such damage, in which
event this Lease shall continue in full force and effect, or (ii) give written
notice to Tenant within thirty (30) days after the date of the occurrence of
such damage of Landlord's intention to terminate this Lease, which termination
shall be effective as of the date of the occurrence of such damage.
<PAGE>   11
         8.3     Total Destruction.  If at any time during the term of this
Lease there is damage which falls into the classification of Total Destruction,
this Lease shall automatically terminate as of the date of such total
destruction.

         8.4     Abatement of Rent.  If Landlord repairs or restores the
Premises pursuant to the provisions of this Section 8, the rent payable
hereunder (including "Additional Rent") for the period during which such
damage, repair or restoration continues shall be abated in proportion to the
degree to which Tenant's use of the Premises is impaired.  Except for abatement
of rent, if any, Tenant shall have no claim against Landlord as a result of any
such damage.  Furthermore, notwithstanding anything above to the contrary,
Tenant shall not be entitled to any rent abatement if the Partial Damage is in
any way caused by Tenant.

9.       Condemnation.

         If the Premises or any portion thereof or other areas appurtenant to
the Premises are taken under the power of eminent domain, or sold under the
threat of the exercise of said power (all of which are herein called
"condemnation"), this Lease shall terminate as to the part so taken as of the
date the condemning authority takes title or possession, whichever first
occurs.  If in the reasonable opinion of Tenant, the portion of the Premises
taken by condemnation materially adversely affects Tenant's operations on the
premises, Tenant may, at Tenant's option, to be exercised in writing only
within thirty (30) days after Landlord shall have given Tenant written notice
of such taking (or in the absence of such notice, within thirty (30) days after
the condemning authority shall have taken possession) terminate this Lease as
of the date the condemning authority takes such possession.  Landlord shall
also have an option to terminate this Lease by notice to Tenant given within
the time limits set forth above if in Landlord's reasonable opinion, it would
not be economically feasible to continue leasing the Premises to Tenant as a
result of such condemnation.  If this Lease is not terminated in accordance
with the foregoing, this Lease shall remain in full force and effect as to the
portion of the Premises remaining, except that the rent shall be reduced in the
proportion that the square feet of the Premises which is taken bears to the
total square feet of the Premises.  Any award for the taking of all or any part
of the Premises under the power of eminent domain or any payment made under
threat of the exercise of such power shall be the property of Landlord, whether
such award shall be made as compensation for diminution in value of the
leasehold, for the taking of the fee, or as severance damages; provided,
however, that Tenant shall be entitled to any award made specifically for loss
of or damage to Tenant's trade fixtures and removable personal property.  In
the event that this Lease is not terminated by reason of such condemnation,
Landlord shall, at Landlord's expense, promptly repair any damage to the
Premises caused by such condemnation.

10.      Taxes.

         10.1 Payment of Real Property Taxes.  Each month, Tenant shall pay
Tenant's Share of the real property taxes applicable to the Premises during the
term of this Lease.  "Tenant's Share" shall be calculated as set forth in
Section 6.3(b).  All such payments shall be made within ten (10) days after
receipt of a written statement from Landlord setting forth Tenant's Share of
such taxes and a copy of the applicable real estate tax bill or bills.  If any
real property taxes paid by Landlord covers any period of time prior to or
after the expiration of the term hereof, Tenant's Share of such taxes shall be
equitably prorated to cover only the period of time within the tax fiscal year
during which this Lease shall be in effect.

         10.2 Definition of "Real Property Tax".  As used herein, the term
"real property tax" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed on the Premises by any authority
having the direct or indirect power to tax, including any city, state or
federal government, or any school, agricultural, sanitary, fire, street,
drainage or other improvement district thereof, as against any legal or
equitable interest of Landlord in the Premises or in the real property of which
the Premises are a part, as against Landlord's right to rent or other income
therefore, and as against Landlord's business of leasing the Premises.  The
term"real property tax" shall also include any tax, fee, levy, assessment or
charge (i) in substitution of, partially or totally, any tax, fee levy,
assessment or charge hereinabove included within the definition of "real
property tax", or (ii) the nature of which was hereinbefore included within the
definition of "real property tax", or (iii) which is imposed by reason of this
transaction or any modifications or changes hereto.

         10.3    Joint Assessment.  If the Premises are not separately
assessed, Tenant's liability shall be an equitable proportion of the real
property taxes for all of the land and improvements included within the tax
parcel assessed, such proportion to be determined by Landlord from the
respective valuations assigned in the assessor's work sheets or such other
information as may be reasonably available, and Landlord's reasonable
determination thereof, in good faith shall be conclusive.

         10.4    Personal Property Taxes.

                 (a)      Tenant shall pay, prior to delinquency, all taxes
assessed against and levied upon trade fixtures, furnishings, equipment and all
other personal property of Tenant contained in the Premises.  When possible,
Tenant shall cause said fixtures, furnishings, equipment and all other personal
<PAGE>   13
property to be assessed and billed separately from the real property of
Landlord.

                 (b)      If any of the Tenant's personal property shall be
assessed with the Landlord's real property, Tenant shall pay Landlord the taxes
attributable to Tenant within twenty (20) days after receipt of a written
statement setting forth the taxes applicable to Tenant's property.

         10.5    Sales and Use Tax.  In addition to the annual rent required
hereunder, Tenant shall also be solely responsible for all sales tax applicable
thereon, or applicable to any other charges or payments due hereunder.

11.      Utilities and Services.  Tenant shall pay for all water, gas, heat,
light, power, telephone and other utilities and services supplied to the
Premises, together with any taxes thereon.  If any such utilities are not
separately metered, Tenant shall pay a reasonable portion of the charges for
utilities jointly metered with other premises.  Tenant shall provide, at its
expense, all janitorial and security services to the Premises.

12.      Assignment and Subletting.

         12.1    Landlord's Consent Required.  Tenant shall not voluntarily or
by operation of law assign, transfer, mortgage, sublet, o otherwise transfer or
encumber all or any part of Tenant's interest in this Lease or in the Premises,
without Landlord's prior written consent, which consent shall not be
unreasonably withheld provided (i) such assignment is to an
entity/individual(s) whose financial integrity is at lease equal to that of
Tenant; (ii) said assignee has demonstrated prior experience in the management
and operation of its business in a similar setting and of the same magnitude;
and (iii) proof thereof satisfactory to Landlord has been delivered to Landlord
at least ten (10) days prior to the effective date of any such transfer.  Any
attempted assignment, transfer, mortgage, encumbrance or subletting without
such consent shall be void, and shall constitute a breach of this Lease.  Any
sale, assignment or other transfer of controlling stock interest in Tenant
shall constitute an "assignment" for purposes hereof.

         12.2    No Release of Tenant.  Regardless of Landlord's consent, no
subletting or assignment shall release Tenant of Tenant's obligation or alter
the primary liability of Tenant to pay the rent and to perform all other
obligations to be performed by Tenant hereunder.  The acceptance of rent by
Landlord from any person shall not be deemed to be a waiver by Landlord of any
provision hereof.  Consent to one assignment or subletting shall not be deemed
consent to any subsequent assignment or subletting. In the event of default by
any assignee of Tenant or any successor of Tenant, in the performance of any of
the terms hereof, Landlord may proceed directly against tenant without the
<PAGE>   14
necessity of exhausting remedies against such successor.  Landlord may consent
to subsequent assignments or subletting of this Lease or amendments or
modifications to this Lease with assignees of Tenant, without notifying Tenant,
or any successor of Tenant and without obtaining its or their consent thereto
and such action shall not relive Tenant of liability under this Lease.

         12.3    Attorney's Fees.  In the event Tenant shall assign or sublet
the Premises or request the consent of Landlord to any assignment or subletting
or if Tenant shall request the consent of Landlord for any act Tenant proposes
to do, then Tenant shall pay Landlord's reasonable attorney's fees incurred in
connection therewith, but Tenant shall be allowed to prepare all necessary
documents for the sublease at its own expense.

         12.4    Landlord's Option to Terminate.  Except as otherwise
specifically set forth herein, in the event that at any time during the term of
this Lease Tenant desire to assign this Lease or to sublet all or part of the
Premises, Tenant shall notify Landlord in writing of the terms of the proposed
assignment or subletting and the area so proposed to be sublet, and Landlord
shall have the option to terminate this Lease wholly in the event of a proposed
assignment or sublet of the whole Premises, or partially as to the portion of
the Premises proposed to be sublet, upon written notice to Tenant within 45
days after receipt of notice of Tenant's intention to assign or sublet.  If
Landlord's election to terminate involves only a portion of the Premises, the
rent specified in this Lease shall be adjusted proportionately on the basis of
the number of square feet retained by Tenant and this Lease shall continue in
full force and effect in all other respects.

13.      Defaults; Remedies.

         13.1    Defaults.  The occurrence of any one or more of the following
events shall constitute a material default and breach of this Lease by Tenant:

                 (a) The vacating or abandonment of the Premises by Tenant.

                 (b) The failure by Tenant to make any payment of rent or any
other payment required to be made by Tenant hereunder, as and when due, where
such failure shall continue for a period of five (5) days after Tenant's
receipt of written notice thereof.  In the event that Landlord serves Tenant
with a notice to pay rent or quit pursuant to applicable unlawful detainer
statues, such notice to pay rent or quit shall also constitute the notice
required by this Section.

                 (c) The failure by Tenant to observe or perform any of the
covenants, conditions or provisions of this Lease to be observed or performed
by Tenant, other than described in
<PAGE>   15
Section 13.1(b) above, where such failure shall continue for a period of thirty
(30) days after written notice thereof from Landlord to Tenant; provided,
however, that if the nature of Tenant's default is such that more than thirty
(30) days are reasonably required for its cure, then Tenant shall not be deemed
to be in default if Tenant commenced such cure within the 30-day period and
thereafter diligently prosecutes such cure to completion.

                 (d) (i) The making by Tenant of any general arrangement or
assignment for the benefit of creditors; (ii) Tenant becomes a "debtor" as
defined in 11 U.S.C. Section 101 or any successor statute thereto (unless, in
the case of a petition filed against Tenant, the same is dismissed within 60
days); (iii) the appointment of a trustee or receiver to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within
thirty (30) days.

         13.2    Remedies.  In the event of any such material default or breach
by Tenant, Landlord may, at any time thereafter, with or without notice or
demand and without limiting Landlord in the exercise of any right or remedy
which Landlord may otherwise have under Florida law by reason of such default
or breach:

                 (a) Terminate tenant's right to possession of the Premises by
any lawful means and terminate this Lease, in which case Tenant shall
immediately surrender possession of the Premises to Landlord.  In such event
Landlord shall be entitled to recover from Tenant all damages incurred by
Landlord by reason of Tenant's default including, but not limited to, the cost
of recovering possession of the Premises; the expense of reletting, including
necessary renovation and alteration of the Premises, reasonable attorney's fees
(including costs), and any real estate commission actually paid; the worth at
the time of award by the court having jurisdiction thereof of the amount by
which the unpaid rent for the balance of the term after the time of such award
exceeds the amount of such rental loss for the same period that Tenant proves
could be reasonably avoided; and that portion of the leasing commission paid by
Landlord pursuant to Section 14 applicable to the unexpired term of this Lease.

                 (b) Maintain Tenant's right to possession in which case this
Lease shall continue in effect whether or not Tenant shall have abandoned the
Premises.  In such event Landlord shall be entitled to enforce all of
Landlord's rights and remedies under this Lease, including the right to recover
the rent as it becomes due hereunder; provided, however, that Landlord shall
have the right to accelerate all amounts owed to Landlord by Tenant under this
Lease as due and payable immediately upon default.
<PAGE>   16
                 (c) Terminate Tenant's right to possession of the Premises
without terminating this Lease and re-enter and take possession of the
Premises, in which case Landlord shall use reasonable efforts to relet the
Premises to another party for Tenant's account and Tenant shall remain liable
for all rent and other amounts due under this Lease and not paid by such other
party; provided, however, that Landlord shall have the right to accelerate all
amounts owed to Landlord by Tenant under this Lease as due and payable
immediately upon default.

                 (d) Pursue any other remedy now or hereafter available to
Landlord under the laws or judicial decisions of the state wherein the Premises
are located.  Unpaid installments of rent and other unpaid monetary obligations
of Tenant under the terms of this Lease shall bear interest from the date due
at the maximum rate then allowable by law.

         13.3    Default by Landlord.  Landlord shall not be in default unless
Landlord fails to perform obligations required of Landlord within a reasonable
time, but in no even later than thirty (30) days after written notice by Tenant
to Landlord and to the holder of any first mortgage or deed or trust covering
the Premises whose name and address shall have theretofore been furnished to
Tenant in writing, specifying wherein Landlord has failed toper form such
obligation; provided, however, that if the nature of Landlord's obligation is
such that more than thirty (30) days are required for performance, then
Landlord shall not be in default if Landlord commences performance within such
30-day period and thereafter diligently prosecutes the same to completion.

         13.4    Late Charges.  Tenant hereby acknowledges that late payment by
Tenant to Landlord of rent and other sums due hereunder will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain.  Such costs include, but are not limited to,
processing and accounting charges, and late charges which may imposed on
Landlord by the terms of any mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Tenant shall
not be received by Landlord or Landlord's designee within ten (10) days after
such amount shall be due then, without any requirement for notice to Tenant,
Tenant shall pay to Landlord a late charge equal to 5% of such overdue amount.
The parties hereby agree that such late charge represents a fair and reasonable
estimate of the casts Landlord will incur by reason of late payment by Tenant.
Acceptance of such late charge by Landlord shall in no event constitute a
waiver of Tenant's default with respect to such overdue amount, nor prevent
Landlord from exercising any of the other rights and remedies granted
hereunder.  In the event that a late charge is payable hereunder, whether or
not collected, for three (3) consecutive installments of rent, then rent shall
automatically become due and payable quarterly in advance, rather
<PAGE>   17
than monthly, notwithstanding Section 4 or any other provision of this Lease to
the contrary.

         13.5    Impounds.  In the event that a late charge is payable
hereunder, whether or not collected, for three (3) consecutive installments of
rent, Tenant shall pay to Landlord, if Landlord shall so request, in addition
to any other payments required under this Lease, a monthly advance installment,
payable at the same time as the monthly rent, as estimated by Landlord, for
real property tax and insurance expenses on the Premises which are payable by
Tenant under the terms of this Lease.  Such fund shall be established to insure
payment when due, before delinquency, of any or all such real property taxes
and insurance premiums.  If the amounts paid to Landlord by Tenant under the
provisions of this section are insufficient to discharge the obligations of
Tenant to pay such real property taxes and insurance premiums as the same
become due, Tenant shall pay to Landlord, upon Landlord's demand, such
additional sums necessary to pay such obligations.  All moneys paid to Landlord
under this section may be intermingled with other moneys of Landlord and shall
not bear interest.  In the event of a default in the obligations of Tenant to
perform under this Lease, then any balance reaming from funds paid to Landlord
under the provisions of this section may, at the option of Landlord, be applied
to the payment of any monetary default of Tenant in lieu of being applied to
the payment of real property taxes and insurance premiums.

14.      Broker's Fee.

         Each party represents and warrants to the other that it has not dealt
with any broker, finder or similar agent in connection with any transaction
contemplated hereunder, other than Lehrer & Co. and In-Site Realty Associates,
Inc., whose fees shall be the sole responsibility of Landlord.  Each party
hereto hereby covenants and agrees to defend, indemnify, hold harmless and
reimburse the other party for, from and against all claims of any kind of any
other broker, finder or similar agent purporting to represent the indemnifying
party in connection with any transaction contemplated hereunder.

15.      Estoppel Certificate.

         (a) Tenant shall at any time upon not less than ten (10) days' prior
notice from Landlord execute, acknowledge and deliver to Landlord a statement
in writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modifications and
certifying that this Lease, as so modified, is in full force and effect) and
the date to which the rent and other charges are paid in advance, if any, and
(ii) acknowledging that there are not, to Tenant's knowledge,  any uncured
defaults on the part of Landlord hereunder, or specifying such defaults if any
are claimed.  Any
<PAGE>   18
such statement may be conclusively relied upon by any prospective purchaser or
encumbrancer of the Premises.

         (b) At Landlord's option, Tenant's failure to deliver such statement
within such time shall be a material default under this Lease or shall be
conclusive upon Tenant (i) that this Lease is in full force and effect, without
modification except as may be represented by Landlord, (ii) that there are no
uncured defaults in Landlord's performance, and (iii) that not more than

month's rent has been paid in advance or such failure may be considered by
Landlord as a default by Tenant under this Lease.

         (c)  If Landlord desires to finance, refinance, or sell the Premises
or any part thereof, Tenant hereby agrees to deliver to any lender or purchaser
designated by Landlord such financial statements of Tenant as may be reasonably
required by such lender or purchaser.  such statements shall include the past
three years financial statements of Tenant.  all such financial statements
shall be received by Landlord and such lender or purchaser in confidence and
shall be used only for the purposes herein set forth.

16.      Landlord's Liability.

         The term "Landlord" as use herein shall mean only the owner or owners
at the time in questions of the fee title or a tenant's interest in a ground
lease of the Premises.  In the event of any transfer of such title or interest,
Landlord herein named (and in case of any subsequent transfers, then the
grantor) shall be relieved from and after the date of such transfer of all
liability in respect of Landlord's obligations thereafter to be performed,
provided that any funds in the hands of Landlord or the then grantor at the
time of such transfer, in which Tenant has an interest, shall be delivered to
the grantee.  The obligations contained in this Lease to be performed by
Landlord shall, subject as aforesaid, be binding on Landlord's successors and
assigns, only during their respective periods of ownership.

17.      Severability.

         The invalidity of any provision of this Lease as determined by a court
of competent jurisdiction shall in no way affect the validity of any other
provision hereof.

18.      Interest on Past-Due Obligations.

         Except as expressly herein provided, any amount due to Landlord not
paid when due shall bear interest at the maximum rate then allowable by law
from the date due.  Payment of such interest shall not excuse or cure any
default by Tenant under this Lease; provided, however, that interest shall not
be payable on late charges incurred by Tenant nor on any amounts upon which
late charges are paid by Tenant.
<PAGE>   19
19.      Additional Rent.

         Any monetary obligations of Tenant to Landlord under the terms of this
Lease shall be deemed to be Additional Rent.

20.      Incorporation of Prior Agreements; Amendments.

         This Lease contains all agreements of the parties with
<PAGE>   20
respect to any matter mentioned herein.  No prior agreement or understanding
pertaining to any such matter shall be effective.  This Lease may be modified
in writing only and signed by the parties in interest at the time of the
modification.  Except as otherwise stated in this Lease, Tenant hereby
acknowledges that neither the real estate broker listed in section 14 hereof
nor any cooperating broker on this transaction nor the Landlord or any
employees or agents of any of said persons has made any oral or written
warranties or representations to Tenant relative to the condition or use by
Tenant or said Premises.

21.      Notices.

         Any notice required or permitted to be given hereunder shall be in
writing and may be given by express courier, personal delivery or by certified
mail, and shall be deemed sufficiently given if addressed to Tenant at the
address of the premises or to Landlord at the address noted next to the
signature of the Landlord.  Either party may, by notice to the other, specify a
different address for notice purposes, except that upon Tenant's taking
possession of the Premises, the Premises shall constitute Tenant's address for
notice purposes.  A copy of all notices required or permitted to be given to
Landlord hereunder shall be concurrently transmitted to such party or parties
at such addresses as Landlord may from time to time hereafter designate by
notice to Tenant.

22.      Waivers.

         No waiver by Landlord of any provision hereof shall be deemed a waiver
of any other provision hereof or of any subsequent breach by Tenant of the same
or any other provision.  landlord's consent to, or approval of, any act shall
not be deemed to render unnecessary the obtaining of Landlord's consent to or
approval of any subsequent act by Tenant.  The acceptance of rent hereunder by
Landlord shall not be  waiver of any preceding breach by Tenant of any
provision hereof, other than the failure of Tenant to pay the particular rent
so accepted, regardless of Landlord's knowledge of such preceding breach at the
time of acceptance of such rent.

23.      Holding Over.

         If Tenant, with Landlord's consent, remains in possession of the
Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month.  Al provisions of this Lease
shall apply to the holdover period.  Al options and rights of first refusal, if
any, granted under the terms of this Lease shall be deemed terminated and be of
no further effect during said month-to-month tenancy.
<PAGE>   21
24.      Cumulative Remedies.

         No remedy or election hereunder shall be deemed exclusive but shall,
wherever possible, be cumulative with all other remedies at law or in equity.

25.      Covenants and Conditions.

         Each provision of this Lease performable by Tenant or Landlord shall
be deemed both a covenant and condition.

26.      Binding Effect; Choice of Law.

         Subject to any provisions hereof restricting assignment or subletting
by Tenant, this Lease shall bind the parties, their personal representatives,
successors and assigns.  This Lease shall be governed by the laws of the State
wherein the Premises are located.

27.      Subordination.

         (a)     This Lease, at Landlord's option, shall be subordinate to any
ground lease, mortgage, deed of trust, or any other hypothecation or security
now or hereafter placed upon the real property of which the Premises are a part
and to any advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.  If any
mortgagee, trustee or ground landlord shall elect to have this Lease prior to
the lien of its mortgage, deed of trust or ground lease, and shall be deemed
prior to such mortgage, deed of trust, or ground lease, whether this Lease is
dated prior or subsequent to the date of said mortgage, deed of trust or ground
lease or the date of recording thereof.

28.      Attorney's Fees.

         If either party named herein brings an action to enforce the terms
hereof or declare rights hereunder, the prevailing party in any such action, on
trial or appeal, shall be entitled to his costs and reasonable attorney's fees,
including all appeals, to be paid by the losing party as fixed by the court.
<PAGE>   22
29.      Landlord's Access.

         Landlord and Landlord's agents shall have the right to enter the
Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders or tenants, and making such
alterations, repairs, improvements or additions to the Premises as Landlord may
deem necessary or desirable.  Landlord's right to inspect the Premises
includes, but is not limited to, the right to take samples and make such
environmental tests as Landlord may deem appropriate from time to time.
Landlord may at any time, place on or about the premises any ordinary "For
Sale" signs and Landlord may at any time during the last 120 days of the term
hereof place on or about the Premises any ordinary "For Lease" signs, all
without rebate of rent or liability to Tenant.

30.      Auctions.

         Tenant shall not conduct, nor permit to be conducted, whether
voluntarily or involuntarily, any auction upon the Premises without first
having obtained Landlord's prior written consent.  Notwithstanding anything to
the contrary in this Lease, Landlord shall not be obligated to exercise any
standard of reasonableness in determining whether to grant such consent.

31.      Signs.

         Any and all signs placed on the exterior of the Premises, including
loading and unloading signs, name signs and number signs, shall be provided by
the Landlord at the Landlord's sole cost and expense and shall be in such form,
style and color as to conform to the standard used throughout the business park
of which the Premises are a part.  Tenant is expressly prohibited from
displaying any signage not authorized by Landlord.

32.      Merger.

         The voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation thereof, or a termination by Landlord, shall not work a merger,
and shall, at the option of Landlord, terminate all or any existing
subtenancies or may, at the option of Landlord, operate as an assignment to
landlord of any or all such subtenancies.

33.      Quite Possession.

         Upon Tenant paying the rent for the Premises and observing and
performing all of the covenants, conditions and provisions on Tenant's part to
be observed and performed hereunder, Tenant shall have quiet possession of the
Premises subject to all of the provisions of this Lease.  Landlord represents
and warrants to Tenant that the individuals executing this Lease on behalf of
Landlord are fully authorized and legally capable of executing
<PAGE>   23
this lease on behalf of Landlord and that such execution is binding upon all
parties holding an ownership interest in the Premises.

34.  Multiple Tenant Business Park.

         Tenant agrees that it will abide by, keep and observe all reasonable
rules and regulations which Landlord may make from time to time for the
management, safety, care and cleanliness of the business park in which the
Premises are located, the parking of vehicles and the preservation of good order
therein as well as for the convenience of other occupants and tenants of the
business park in which the Premises are located.

35.  Security Measures.

         Tenant hereby acknowledges that the rental payable to Landlord
hereunder does not include the cost of guard service or other security measures,
and that Landlord shall have no obligation whatsoever to provide same. Tenant
assumes all responsibility for the protection of Tenant, its agents and invitees
from acts of third parties.

36.  Easements.

         Landlord reserves to itself the right, from time to time, to grant such
easements, rights, and decisions that Landlord deems necessary or desirable, and
to cause the recordation of site plans, parcel maps, restrictions and similar
instruments so long as such easements, rights, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by

<PAGE>   24
Tenant. Tenant shall sign any of the aforementioned documents upon request of
Landlord and failure to do so shall constitute a material breach of this Lease.

37.  Performance' Under Protest.

If at any time a dispute shall arise as to any amount or sum of money to be paid
by one party to the other under the provisions hereof, the party against whom
the obligation to pay the money is asserted shall have the right to make payment

                       FIRST ADDENDUM TO WINGATE COMMONS
                            BUSINESS PARK NET LEASE

         This First Addendum to that certain Wingate Commons Business Park Net
Lease (the "Lease") dated September 27, 1991 by and between REYNOLDS METALS
DEVELOPMENT COMPANY, a Delaware corporation ("Landlord"), and LIFECARE
INVESTMENTS, INC., a Delaware corporation ("Tenant"), hereby modifies and
amends the lease to include the following:

1.       Notwithstanding anything to the contrary contained in Section 3.1 of
         the Lease, Tenant shall have the option of terminating this Lease at
         the end of the tenth and the fifteenth Lease Year by giving Landlord
         not less than ninety (90) days' prior written notice.

2.       Sections 3.2 and 4.2 of the Lease are hereby deleted.

3.       Notwithstanding anything to the contrary contained in Section 3.3 of
         the Lease, Tenant shall not be required to pay Rent until the
         Commencement Date.

4.       Tenant shall have the option of purchasing the Premises during the
         first five (5) Lease Years of the Lease at the purchase price set
         forth below opposite the Lease Year in which the purchase is made (the
         "Option Price"):

                          Lease Year 1  $ 1,185,150.00
                          Lease Year 2  $ 1,223,443.00
                          Lease Year 3  $ 1,284,700.00
                          Lease Year 4  $ 1,347,975.00
                          Lease Year 5  $ 1,351,241.00

         Tenant shall exercise such option by giving written notice thereof to
         Landlord.  If Tenant exercises its option, closing shall occur within
         sixty (60) days after the date of the exercise by Tenant of its option
         and time is of the essence.  Upon payment of the Option Price,
         Landlord will convey the Premises to Tenant by warranty deed, subject
         to any leases, easements, conditions and restrictions of record
         affecting the Premises existing on the date of the exercise by Tenant
         of its option. If Tenant does not exercise its option to purchase the
         Premises or Tenant does not close the purchase within sixty (60) days
         after the exercise by Tenant of its option to purchase the Premises
         because of the fault of Tenant, Tenant's option to purchase the
         Premises pursuant to this paragraph 4 shall expire and be of no
         further force and effect.

5.       Notwithstanding the provisions of paragraph 4 above, if Landlord,
         during the first five (5) Lease Years, receives a bona fide offer to
         purchase the Premises
<PAGE>   35
         from a third party (the "Third Party Offer"), Landlord shall so advise
         Tenant by notice in writing setting forth the terms and conditions of
         the Third Party Offer.  For a period of ten (10) days after receipt of
         said notice, Tenant shall have the option of purchasing the Premises
         at the higher of the Option Price or the price specified in the Third
         Party Offer by giving written notice thereof to Landlord.  If Tenant
         exercises its option under this paragraph 5, closing shall occur
         within sixty (60) days after the date of the exercise by Tenant of its
         option contained in this paragraph 5 and time is of the essence.  Upon
         payment of the Option Price or the price set forth in the Third Party
         Offer, whichever is applicable, Landlord will convey the Premises to
         Tenant by warranty deed, subject to any leases, easements, conditions
         and restrictions of record affecting the Premises existing on the date
         of the exercise by Tenant of its option to purchase the Premises
         pursuant to this paragraph 5. If Tenant does not exercise its option
         to purchase the Premises pursuant to this paragraph 5 within such ten
         (10) day period by written notice to Landlord or Tenant does not close
         the purchase within sixty (60) days after the exercise by Tenant of
         its option to purchase the Premises pursuant to this paragraph 5
         because of the fault of Tenant, Tenant's option to purchase the
         Premises pursuant to paragraph 4 above or this paragraph 5 shall
         expire and shall be of no further force and effect and Landlord may
         proceed to sell the Premises to such third party on the terms and
         conditions set forth in the Third Party Offer.

6.       Notwithstanding anything to the contrary contained in Section 4 of the
         Lease, the following shall be applicable to the payment of Monthly
         Rent and Additional Rent during the periods set forth below:

         (a)     During the first two (2) months of the term of the Lease,
                 Tenant shall not be required to pay Monthly Rent.  From the
                 third month through the tenth month of the term of the Lease,
                 the Monthly Rent payable by Tenant shall be reduced by fifty
                 percent (50%).

         (b)     The Monthly Rent shall not be adjusted pursuant to the
                 provisions of Section 4.1(b) of the Lease until after the
                 second Lease Year. Thereafter the provisions of Section 4.1(b)
                 of the Lease shall be applicable; provided, however, that the
                 Adjusted Monthly Rent shall not be increased (i) by more than
                 twenty percent (20%) during the first five (5) Lease Years,
                 using the Monthly Rent of $8,308.23 for the first Lease Year
                 as the base, (ii) by more than twenty percent (20%) during the
<PAGE>   36
                 second five (5) Lease Years, using the Adjusted Monthly Rent
                 for the sixth Lease Year as the base, (iii) by more than
                 twenty percent (20%) during the third five (5) Lease Years
                 using the Adjusted Monthly Rent for the eleventh Lease Year as
                 the base, and (iv) by more than twenty percent (20%) during
                 the last five (5) Lease Years, using the Adjusted Monthly Rent
                 for the sixteenth Lease Year as the base.

7.       It is hereby understood and acknowledged by Tenant that the Premises
         is part of a business park known as Wingate Commons Business Park and
         that the other tenants of the said business park together with their
         customers, employees and invitees have mutual use of the Common Areas
         including but not limited to all parking areas, driveways and roads
         located in the park of which the Premises are a part and that Landlord
         has the right to temporarily close any part of said Common Areas for
         such period of time as is reasonably necessary to make repairs or
         alterations to the Common Areas or to the buildings located adjacent
         thereto.  Accordingly, Tenant agrees to indemnify and save Landlord
         harmless from and against any and all liabilities, losses, damages,
         costs, expenses (including reasonable attorneys' fees) in connection
         with any injury to, or the death of, any person or any damage to or
         loss of property resulting from the use of the aforesaid Common Areas
         by others or the temporary closure of same by Landlord.  Landlord will
         give Tenant five (5) days' notice of any non-emergency repairs,
         alterations or improvements and reasonable notice of emergency
         repairs, alterations or improvements to be made to the Common Areas or
         to the buildings located adjacent thereto which could restrict ingress
         or egress to the Premises.

8.       Notwithstanding anything to the contrary contained in Section 12 of
         the Lease, Tenant shall have the right at the inception of the Lease
         to sublease twenty-five percent (25%) of the Building to another third
         party for use as executive offices.  It is agreed that such third
         party subleasing a portion of the Building for use as executive
         offices may enter into additional subleases of parts of such portion
         with others.  Any other subleases not covered by this paragraph B
         shall be subject to all the terms and provisions of Section 12 of the
         Lease.

9.       For purposes of Section 18 of the Lease, the term "maximum rate then
         allowable by law" shall mean eighteen percent (18%) per annum.

                          Lease, Tenant shall not be required to pay Monthly
                          Rent.  During the third and fourth months of the term

                          shall be reduced by fifty percent (50%)."

                 following two sentences at the end thereof:

                 "Upon final completion of the Improvements, occupancy of the
                 Premises by Tenant and full compliance with the conditions set
                 forth above, if the amount paid by Landlord to Contractor
                 and/or any lienor on behalf of Tenant is less than $271,520,
                 Landlord shall pay to Tenant an amount equal to the difference
                 between $271,520 and the amount previously paid by Landlord
                 pursuant to this Section 43(f), which amount shall be used by
                 Tenant to pay for other business expenditures of Tenant.  In
                 no event shall Landlord be required to
