           ------------------                           --------   --------



This Amendment Number 2 to Schedule 13D is filed by Steven A. Cohen ("Cohen")
and S.A.C. Capital Advisors, LLC, a Delaware limited liability company ("SAC
Advisors" and, together with Cohen, the "Reporting Persons"), relating to the
shares of common stock, $0.01 par value per share ("Shares") of Substance Abuse
Technologies, Inc. (formerly known as U.S. Alcohol Testing of America, Inc.), a
Delaware corporation (the "Company"), held by Cohen and S.A.C. Capital
Associates, LLC, an Anguillan limited liability company ("SAC Associates"),
respectively.  SAC Associates is not listed as a Reporting Person on this
Schedule 13D because all voting and investment power (as defined in Rule 13d-3)
has been vested with SAC Advisors pursuant to an Investment Management
Agreement.

This Amendment No. 2 is filed to report that on November 8, 1996 the Reporting
Persons entered into a Convertible Loan and Warrant Agreement (the "Agreement")
with the Company, pursuant to which the Reporting Persons loaned $5,000,000 to
the Company in return for Convertible Senior Promissory Notes (the "Notes") and
purchased stock purchase warrants (the "Warrants").  This Amendment No. 2
summarizes the terms of the Agreement and updates the Reporting Person's
previous disclosures.

ITEM 1.  SECURITY AND ISSUER

No amendment.

ITEM 2.  IDENTITY AND BACKGROUND

No amendment.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

All funds utilized by SAC Advisors to acquire the Shares that they held before
entering into the Agreement (the "Owned Shares"), to loan to the Company and to
purchase Warrants on behalf of SAC Associates were derived from SAC Associates'
working capital and all funds utilized by Cohen were derived from personal
funds.  Such funds may include margin debt incurred from time to time in the
ordinary course of business pursuant to customary margin agreements with Spear,
Leeds & Kellogg.

ITEM 4.  PURPOSE OF TRANSACTION

The Reporting Persons acquired the Owned Shares for the purpose of investment
because they believed the Company presented a favorable investment opportunity.
The Reporting Persons continue to believe that the Company presents a favorable
investment opportunity and continue to act for investment purposes.  However,
as a result of the Reporting Person's increased investment in the Company
arising under the Agreement and the possibility of ultimately obtaining
additional Shares through the Notes and the Warrants, the Reporting Persons
intend from time to time to sell some or all of the Owned Shares.  Whether the
Reporting Persons actually effect such sales will depend on their continuing
evaluation of the diversity of their investment portfolio, as well as the price
level of the Shares, available opportunities to dispose of the Shares,
conditions in the securities markets and general economic and industry
conditions.  These sales may take place in the open market, through privately
negotiated transactions with third parties, or otherwise.

                                 SCHEDULE 13D

           ------------------                           --------   --------



The Reporting Persons have, as part of the Agreement, agreed with the Company
to certain volume restrictions on Open Market Transactions (as defined below)
involving sales of the Owned Shares.  There are, however, no restrictions on
sales by the Reporting Persons of the first One Million (1,000,000) of the
Owned Shares sold in Open Market Transactions.  After the sale of One Million
Owned Shares in Open Market Transactions, the Reporting Persons have agreed
with the Company that, unless waived by the Company, they will not sell any of
the remaining Owned Shares in Open Market Transactions unless:  (i) the sales
price for such Shares (before any fees or commissions) is equal to or greater
than the "Limit Price" (defined in the Agreement as $2.00 per share subject to
certain adjustments), (ii) the volume of Shares sold by the Reporting Persons
on any trading day at a price below the Limit Price (before any fees or
commissions) does not exceed twenty-five percent (25%) of the average daily
trading volume of the Company's common stock reported for the five trading days
immediately preceding the date of such sale, provided that any sales by the
Reporting Persons during the immediately preceding five trading days at a price
below the Limit Price shall be excluded from the calculation of the average
daily trading volume, or (iii) such shares are sold at the best offer price.
For purposes of the Agreement, the term "Open Market Transactions" means
transactions that are reported on the consolidated quotation system other than
block trades (as defined under Exchange Act Rule 10b-8).  These volume sales
limitations do not extend to any other transactions in the Shares or to any
Shares that the Reporting Persons may acquire in the future.

With the exception of the execution of the Agreement as described in this Item
and in Item 6, as of the date of this Amendment No.  2, none of the Reporting
Persons or the entities and individuals described in Item 2 of the original
Schedule 13D has any plans or proposals which would result or relate to any of
the transactions described in paragraphs (a) through (j) of Item 4 of Schedule
13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a)     The Reporting Persons beneficially own 2,342,200 Shares
                 representing 6.58% of the 35,603,092 Shares reported by the 
                 Company as outstanding as of September 12, 1996.

         (b)     No amendment.

         (c)     Except as set forth in Annex 1 hereto, no transactions in
                 Shares were effected since July 30, 1996.

         (d)     No amendment.

         (e)     Not applicable.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER.

On November 8, 1996, the Reporting Persons and the Company executed the
Agreement, which provides for the Reporting Persons to lend the Company
$5,000,000.  The Notes are due and payable on November 8, 1999 and bear
interest at the rate of 7% per annum, payable quarterly.  The Notes are
convertible into Shares at any time after July 1, 1997.  The conversion price
(the "Conversion Price") is initially set at the rate of Two Dollars ($2.00)
per share.  This Conversion

           ------------------                           --------   --------



Price is subject to adjustment downward (the "Market Price Adjustment") during
the period from May 1, 1997 through May 1, 1998 based on the average market
price for Shares over the preceding 65 trading days, provided that the
Conversion Price will not be reduced below $1.375 as a result of this
adjustment.  In addition, the Conversion Price is subject to reduction pursuant
to certain antidilution provisions if the Company sells Shares at less than the
Conversion Price, or issues options or convertible securities which can be
exercised at a price less than the Conversion Price.

Under the Agreement, as long as any portion of the Notes are outstanding and
thereafter as long as certain conditions are met, the holders of the Notes may
name one person to the Company's Board of Directors or may exercise observer
rights at meetings of the Board of Directors.  The Agreement also imposes
certain negative and affirmative covenants on the Company as long as any
balance remains outstanding under the Notes.  Among other things, these
covenants restrict the Company's ability to engage in acquisitions (other than
the proposed acquisition of the Company's two majority owned subsidiaries, Good
Ideas Enterprises, Inc. and U.S. Drug Testing, Inc.) of companies that are not
engaged exclusively in, or engaged in a business directly related to, the
business of substance abuse testing, to pay dividends, to incur indebtedness
(as defined in the Agreement) senior to the Notes, to engage in certain related
party transactions, to assign the rights in certain intellectual property, to
terminate the employment of the Company's chief executive officer, to incur
other indebtedness (as defined in the Agreement) in excess of $1 million, to
sell or otherwise dispose of any subsidiary or division of the corporation
(with the exception of Good Ideas Enterprises, Inc.), to engage in other
transactions with a value in excess of $1 million, and to amend the Company's
Certificate of Incorporation or Bylaws or file resolutions of the Board of
Directors or enter into any agreement that would adversely affect the rights
and priorities of the Reporting Persons.  The Reporting Persons also have the
right to purchase additional Shares in any public or private sale of Shares
effected by the Company and to acquire additional Shares under certain other
circumstances.

In addition, pursuant to the Agreement, the Reporting Persons purchased for
$1,000 Warrants to purchase 2,500,000 Shares at an exercise price of $2.00 per
share.   The Warrants are not exercisable to any extent before July 1, 1997,
and thereafter are exercisable only to the extent that, when added together
with any other Shares beneficially owned by the Reporting Persons, would not
result in the Reporting Persons being deemed to be greater than ten percent
stockholders subject to Section 16 of the Securities Exchange Act of 1934.
Notwithstanding the foregoing, the Warrants become fully exercisable on April
30, 2000 and expire on June 30, 2000.  The number of Shares which may be
purchased pursuant to the Warrants is subject to a downward adjustment, but not
to less than 2,000,000 Shares, in the event that the Conversion Price of the
Note is reduced, such that the number of Shares purchasable pursuant to the
Warrants will be reduced at a rate of one Share for each 2.2727 additional
Shares which may be obtained upon conversion of the Notes as a result of any
Market Price Adjustment. In addition, the Exercise Price is subject to
reduction and the number of Shares that may be purchased under the Warrants is
subject to increase pursuant to certain antidilution provisions if the Company
sells Shares at less than the Exercise Price.   The Warrants are transferable,
subject to the conditions in the legend thereon.

The Conversion Price, Exercise Price, Limit Price and other price provisions of
the Notes and the Warrants may be adjusted upward or downward to reflect
reverse stock splits, stock splits, stock dividends, and other similar
transactions.

Under the Agreement, the Company agreed promptly to register under the
Securities Act of 1933 the Shares issuable under the Notes and the Warrants.
In the event the registration statement is not filed and the Company does not
use its best efforts to have the registration statement declared effective
within 90 days, the Company must pay the Reporting Persons a cash penalty equal
to 10% of the outstanding principal under the Notes.  In addition, during times
(if any) when the Company has not maintained the registration statement in
effect for a specified period or has failed to keep current any prospectus
forming a part of such registration statement, the Exercise Price of the
Warrants may be paid by netting out Shares otherwise issuable thereunder.
Finally, the Company and the Reporting Persons entered into a Registration
Rights Agreement, pursuant to which the Reporting Persons have "piggyback"
rights to include Shares in any registration statement filed by the Company,
and on one occasion to demand registration of Shares if the Shares issued upon
conversion of the Notes or exercise of the Warrants are not freely tradable.
The right to demand registration may be assigned to a transferee of the
securities.

                                       3
<PAGE>   12
                 "Underlying Common Stock" shall mean (i) the shares of Common
Stock issued or issuable upon conversion of the Notes or upon exercise of the
Warrant and (ii) any Common Stock issued or issuable with respect to the
securities referred to in clause (i) above by way of stock dividend or stock
split or in connection with a combination of shares, recapitalization, merger,
consolidation or other reorganization.

         2.      PURCHASE AND SALE OF THE NOTE AND THE WARRANTS.

                 2.1.     The Loan.  The Noteholders will loan the Company the
Loan Amount subject to the terms and conditions set forth in this Agreement.
On the Effective Date, (i) the Noteholders shall transfer the Loan Amount to an
account of the Company pursuant to instructions attached hereto as Exhibit E,
and (ii) the Company shall issue to each of the Noteholders a Convertible
Senior Promissory Note each in the principal amount equal to Two Million Five
Hundred Thousand Dollars ($2,500,000), in the form attached hereto as Exhibit B
(each such Convertible Senior Promissory Note, a "Note").

                 2.2.     The Warrant.  On the Effective Date, the Company
shall issue and sell to each of the Noteholders a stock purchase warrant in the
form attached hereto as Exhibit C (the "Warrant").  On the Effective Date, each
of the Noteholders shall pay the Company Five Hundred Dollars ($500.00) in
consideration for the issuance and sale of the Warrant.

                 2.3.     Issue Price Allocation.  The parties hereto
acknowledge that the Loan and the Warrant are an "investment unit" within the
meaning of Section 1273(c)(2) of the Internal Revenue Code of 1986, as amended
(the "Code"), that the "issue price," within the meaning of Section 1273(b) of
the Code, of the Loan shall be Five Million Dollars ($5,000,000) and the "yield
to maturity," based on such issue price, of the Loan is seven percent (7%).
Except as otherwise required by law, the parties hereto agree that such issue
price and yield to maturity shall be used to determine the amount of "original
issue discount" accruing and to be reported on the Loan pursuant to Section
1272 of the Code and the regulations promulgated thereunder.

         3.      LOAN TERM; INTEREST; REPAYMENT; PREPAYMENT.  The term of the
Loan will begin on the Effective Date and end on the third anniversary of the
Effective Date (the "Maturity Date").  Interest on the unpaid principal balance
on any Note (such unpaid principal balance is referred to as the "Outstanding
Balance") will accrue from the Effective Date at the rate of seven percent (7%)
per annum, calculated on the basis of a 360 day year and actual days elapsed
until the entire Outstanding Balance has been repaid or has been converted
pursuant to this Agreement.  The Company will pay to the Noteholders all
interest accrued on the Outstanding Balance in quarterly installments with each
installment due and payable on March 15, June 15, September 15 and December 15
(or the first business day after such dates) of each year during the term of
the Loan (such that the first installment of interest shall accrue from the
Effective Date through and be due and payable on December 15, 1996), except
that all accrued but unpaid interest shall be due and payable on the earlier to
occur of the time of conversion with respect to the portion of the Outstanding
Balance being converted or on the Maturity Date.  Any accrued interest that is
not paid when due shall at a Noteholder's option (A) remain due and payable and
accrue at the rate set forth in Section 13.2(ii), or (B) be converted to
principal and





                                       4
<PAGE>   13
the Outstanding Balance shall be correspondingly increased.  To the extent not
previously converted pursuant to Section 5 hereof, the entire Outstanding
Balance shall be due and payable on the Maturity Date.  The Outstanding Balance
and all accrued interest and any and all other sums payable to the Noteholders
hereunder may not be prepaid prior to the Maturity Date without the consent of
the Noteholders in their sole and absolute discretion.

         4.      UNSECURED LOAN.  The Loan shall not be secured by any assets
of the Company, provided, however, that upon a default of the Company under
this Agreement, the Noteholders shall be entitled to the remedies specified in
Section 13.

         5.      CONVERSION.  The Outstanding Balance of any Note is
convertible on the following basis:

                 5.1.     Optional Conversion.  A Noteholder may at any time
and from time to time after July 1, 1997 convert all or any portion of the
Outstanding Balance under a Note into a number of shares of Common Stock
determined by dividing the Outstanding Balance to be so converted by the
"Conversion Price" as such term is determined at the time of conversion
pursuant to this Agreement.  As of the Effective Date, the Conversion Price
shall be Two Dollars ($2.00) as such shall be adjusted from time to time as
provided in this Agreement.  Except in the case of a conversion of the full
Outstanding Balance under a Note, the amount of the Outstanding Balance
converted at any one time shall be equal to or exceed Two Hundred Fifty
Thousand Dollars ($250,000) but shall be an amount that avoids the issuance of
fractional shares.

                 5.2.     Reservation of Securities.  Through the Maturity
Date, the Company shall reserve for issuance such number and type of securities
as the Noteholders are entitled to receive upon conversion of the Notes.  Prior
to the issuance of any equity securities (or any instrument exercisable for or
convertible into equity securities) and whenever otherwise required to satisfy
this Section 5.3, the Company will amend its Articles of Incorporation to the
extent necessary to ensure that there is reserved for issuance a sufficient
quantity of such equity securities (and Common Stock into which such equity
securities may be convertible) as the Noteholders are entitled to receive upon
conversion of the Notes.

         6.      ADJUSTMENT OF CONVERSION PRICE.  In order to prevent dilution
of the rights granted under this Agreement, the Conversion Price shall be
subject to adjustment from time to time as provided in this Section 6.

                 6.1.     Adjustment Period Adjustments.  During the period
beginning on May 1, 1997 through the earlier of (i) the date that the entire
Outstanding Balance of the Loan is converted into Common Stock and (ii) May 1,
1998 (the "Adjustment Period"), the Conversion Price shall be reduced to the
Average Market Price (as defined below) each time that the Average Market Price
is below the then-current Conversion Price.  For purposes of this Section 6.1,
the Average Market Price as of any day during the Adjustment Period shall be
the average of the Market Prices for each of the sixty-five (65) trading days
preceding such day (any such trading day, a "Calculation Day"), provided that
the Market Price on any Calculation Day shall be excluded from the calculation
of Average Market Price if either (a) one of the Noteholders sold Common Stock
in Open Market Transactions (as defined in Section 12) on that Calculation Day,





                                       5
<PAGE>   14
or (b) the Calculation Day is within twenty-one (21) trading days after the day
on which one of the Noteholders sold Common Stock in an Open Market
Transaction.  Such adjustments will occur automatically during the Adjustment
Period to the extent that the Average Closing Price for a given date of
adjustment is less than the then-current Conversion Price.  Notwithstanding the
foregoing, in no event shall the Conversion Price be reduced below the "Floor
Price" (as defined below) as a result of this Section 6.1.  For purposes of
this Section 6.1, the Floor Price shall be $1.375, as such shall be adjusted
from time to time as provided in this Agreement.  There shall be no upward
adjustments of the Conversion Price, regardless of any increases in the Average
Closing Price during the Adjustment Period.

                 6.2.     Effect on Conversion Price of Certain Events.  If and
whenever on or after the Effective Date, the Company issues or sells any share
of Common Stock (other than upon the exercise of an Option or the conversion of
Convertible Securities outstanding immediately before the Effective Date), or
in accordance with this Section 6.2 is deemed to have issued or sold any share
of Common Stock, for a consideration per share less than the Conversion Price
in effect immediately prior to such time, then immediately upon such issuance
or sale, independent of Section 6.1 hereof, the Conversion Price shall be
reduced to the price per share at which such share of Common Stock has been
issued or sold or is deemed pursuant to this Section 6 to have been issued or
sold.  For purposes of determining the adjusted Conversion Price under this
Section 6.2, the following shall be applicable:

                          (i)     Issuance of Rights or Options.  If on or
after the Effective Date the Company in any manner issues, grants or sells any
Options and the price per share for which a share of Common Stock is issuable
upon the exercise of any such Option, or upon conversion or exchange of any
Convertible Security issuable upon exercise of such Option, is less than the
Conversion Price in effect immediately prior to the time of the granting or
sale of such Option, then such share of Common Stock shall be deemed to have
been issued and sold by the Company at such time for such price per share.  For
purposes of this Section 6.2(i), the "price per share for which a share of
Common Stock is issuable" shall be equal to the sum of the amount of
consideration (if any) received or receivable by the Company with respect to
the issuance, grant or sale of the Option, plus the amount of consideration (if
any) that would be received by the Company with respect to exercise of the
Option in full plus the amount of consideration (if any) that would be received
by the Company with respect to conversion or exchange in full of any
Convertible Security issuable upon exercise of such Option, all divided by the
total number of shares of Common Stock issuable upon exercise of the Option and
conversion or exchange of the Convertible Security.  No further adjustment of
the Conversion Price shall be made upon the actual issue of such Common Stock
or of such Convertible Security upon the exercise of such Options or upon the
actual issue of such Common Stock upon conversion or exchange of such
Convertible Security.

                          (ii)    Issuance of Convertible Securities.  If on or
after the Effective Date the Company in any manner issues, grants or sells any
Convertible Security and the price per share for which a share of Common Stock
is issuable upon conversion or exchange thereof is less than the Conversion
Price in effect immediately prior to the time of such issue or sale, then such
share or shares of Common Stock shall be deemed to have been issued and sold by
the Company at such time for such price per share.  For the purposes of this
Section 6.2(ii), the "price per share





                                       6
<PAGE>   15
for which a share of Common Stock is issuable" shall be equal to the sum of the
amount of consideration (if any) received or receivable by the Company with
respect to the issuance, grant or sale of the Convertible Security plus the
amount of consideration (if any) that would be received by the Company with
respect to the conversion or exchange of such Convertible Security in full, all
divided by the total number of shares of Common Stock issuable upon conversion
or exchange of the Convertible Security.  No further adjustment of the
Conversion Price shall be made upon the actual issue of such Common Stock upon
conversion or exchange of any Convertible Security, and if any such issue or
sale of such Convertible Security is made upon exercise of any Options for
which adjustments of the Conversion Price has been or is to be made pursuant to
other provisions of this Section 6, no further adjustment of the Conversion
Price shall be made by reason of such issue or sale.

                          (iii)   Change in Option Price or Conversion Rate.
If the amount to be received by the Company upon the exercise of any Options
outstanding as of the Effective Date, the additional consideration, if any,
payable upon the issuance, conversion or exchange of any Convertible Securities
outstanding as of the Effective Date, or the rate at which any Convertible
Securities outstanding as of the Effective Date are convertible into or
exchangeable for Common Stock changes at any time after the Effective Date,
then such Option or Convertible Security and the Common Stock deemed issuable
upon exercise, conversion or exchange thereof shall be deemed for purposes of
this Section 6.2 to have been issued as of the date of such change; provided
that no such change shall at any time cause the Conversion Price hereunder to
be increased.

                          (iv)    Treatment of Expired Options and Unexercised
Convertible Securities.  Upon the expiration of any Option described in Section
6.2(i) or the termination of any right to convert or exchange any Convertible
Securities described in Section 6.2(ii) without the exercise or conversion in
whole or in part of such Option or Convertible Security, the Conversion Price
then in effect shall be adjusted immediately to the Conversion Price which
would have been in effect at the time of such expiration or termination had
such Option or Convertible Securities, never been issued, granted or sold;
provided that if such expiration or termination would result in an increase in
the Conversion Price then in effect, such increase shall not be effective until
the later of (A) the date of such expiration or termination or (B) thirty (30)
days after the Company has delivered notice of such expiration or termination
to the Noteholders.  For purposes of this Section 6.2, the expiration or
termination of any Option or Convertible Security which was outstanding as of
the Effective Date shall not cause the Conversion Price hereunder to be
adjusted unless, and only to the extent that, a change in the term of such
Option or Convertible Security caused it to be deemed to have been issued after
the Effective Date pursuant to Section 6.2(iii).

                          (v)     Calculation of Consideration Received.  If
any Common Stock, Options or Convertible Securities are issued or sold or
deemed to have been issued or sold for cash, the consideration received
therefor shall be deemed to be the net amount received by the Company therefor.
In case any Common Stock, Options or Convertible Securities are issued or sold
for a consideration other than cash, the amount of the consideration other than
cash received by the Company shall be the fair value of such consideration,
except where such consideration consists of securities, in which case the
amount of consideration received by the Company shall be





                                       7
<PAGE>   16
the Market Price thereof as of the date of receipt.  In case any Common Stock,
Options or Convertible Securities are issued to the owners of the non-surviving
entity in connection with any merger in which the Company is the surviving
corporation, the amount of consideration therefor shall be deemed to be the
fair value of such portion of the net assets and business of the non-surviving
entity as is attributable to such Common Stock, Options or Convertible
Securities, as the case may be.  The fair value of any consideration other than
cash or securities shall be determined jointly by the Company and the
Noteholders.  If such parties are unable to reach agreement, such fair value
shall be determined by appraisal pursuant to Section 17.15.

                          (vi)    Integrated Transactions.  In case any Option
is issued in connection with the issue or sale of other securities of the
Company, together comprising one integrated transaction in which no specific
consideration is allocated to such Options by the parties thereto, the Options
shall be deemed to have been issued without consideration.

                          (vii)   Each Series a Separate Security.  In case an
agreement relating to Options or Convertible Securities provides that more than
one exercise price, conversion or exchange provisions are applicable to the
securities issuable thereunder, then the securities subject to each different
exercise price, conversion or exchange provisions shall be deemed to be subject
to separate Options or Convertible Securities for purposes of applying this
Section 6.2.

                          (viii)  Treasury Shares.  The Common Stock
outstanding at any given time does not include shares owned or held by or for
the account of the Company or any Subsidiary, and the disposition of any shares
so owned or held shall be considered an issue or sale of Common Stock.

                          (ix)    Record Date.  If the Company takes a record
of the holders of Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in Common Stock, Options or in
Convertible Securities or (B) to subscribe for or purchase Common Stock,
Options or Convertible Securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such
other distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                 6.3.     Certain Sales of Common Stock.  If and whenever on or
after the Effective Date the Company issues or sells, or in accordance with
Section 6.2 is deemed to have issued or sold, any share of Common Stock for a
consideration per share that is equal to or greater than the Conversion Price
in effect immediately prior to such issuance or sale, but that does not exceed
the lower of the Market Price per share of Common Stock on the day of such
issuance or sale and one hundred and fifteen percent (115%) of the Conversion
Price in effect immediately prior to such issuance or sale, then immediately
upon such issuance or sale, independent of Section 6.1 hereof, the Conversion
Price shall be reduced to the price determined by multiplying the Conversion
Price in effect immediately prior to such issuance or sale by a fraction, the
numerator of which shall be the sum of (i) the number of shares of Common Stock
outstanding immediately prior to such issuance or sale multiplied by the Market
Price per share of Common Stock on the day of such issuance or sale, plus (ii)
the number of shares issued or sold, or in accordance with Section 6.2 deemed
to have been issued or sold, multiplied by the price per share at which such





                                       8
<PAGE>   17
Common Stock was issued or sold, or in accordance with Section 6.2 is deemed to
be issued or sold, and the denominator of which shall be the product of (A) the
total number of shares of Common Stock outstanding immediately after such
issuance or sale, multiplied by (B) the Market Price per share of Common Stock
on the day of such issuance or sale.

                 6.4.     Subdivision or Combination of Common Stock.  If the
Company at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, the Conversion Price, the Floor
Price and the Limit Price (as defined under Section 12) in effect immediately
prior to such subdivision, and the Market Price valuations for trading days
preceding such event that are utilized under Section 6.1 with respect to
periods straddling the date of such subdivision, shall be proportionately
reduced.  If the Company at any time combines (by reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, the Conversion Price, the Floor Price and the Limit
Price in effect immediately prior to such combination, and the Market Price
valuations for trading days preceding such event that are utilized under
Section 6.1 with respect to periods straddling the date of such combination,
shall be proportionately increased.

                 6.5.     Reorganization, Reclassification, Consolidation,
Merger or Sale.  Any recapitalization, reorganization, reclassification,
consolidation, merger, sale of all or the majority of the Company's assets or
other transaction, in each case which is effected in such a way that the
holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for Common Stock is referred to herein as "Organic Change." Prior to
the consummation of any Organic Change, the Company shall make appropriate
provision (in form and substance satisfactory to the Noteholders) to insure
that the Noteholders shall thereafter have the right to acquire and receive, in
lieu of or in addition to (as the case may be) the shares of Common Stock
immediately theretofore acquirable and receivable upon the conversion of the
Notes, such shares of stock, securities or assets as may be issued or payable
in connection with such Organic Change with respect to or in exchange for the
number of shares of Common Stock acquirable and receivable had the Notes been
fully converted immediately prior to such Organic Change.  In any such case,
the Company shall make appropriate provision (in form and substance
satisfactory to the Noteholders) with respect to such holders' rights and
interests to insure that the provisions of this Section 6 and Section 15 hereof
shall thereafter be applicable to the Notes (including, in the case of any such
consolidation, merger or sale in which the successor entity or purchasing
entity is other than the Company, an immediate reduction in the Conversion
Price to the value of the Common Stock reflected by the terms of such
consolidation, merger or sale, if the value so reflected is less than the
Conversion Price in effect immediately prior to such consolidation, merger or
sale).  The Company shall not effect any such consolidation, merger or sale,
unless prior to the consummation thereof, the successor entity (if other than
the Company) resulting from consolidation or merger or the entity purchasing
such assets assumes by written instrument (in form and substance satisfactory
to the Noteholders), the obligation to deliver to each such holder such shares
of stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

                 6.6.     Certain Events.  If any event occurs of the type
contemplated by the provisions of this Section 6 but not expressly provided for
by such provisions (including, without





                                       9
<PAGE>   18
limitation, the granting of stock appreciation rights, phantom stock rights or
other rights with equity features or any dividend or distribution of the
capital stock issued by any Person other than the Company), then the Company's
Board of Directors shall make an appropriate adjustment in the Conversion
Price, the Floor Price and the Limit Price in effect immediately prior to such
event, and the Market Price valuations for trading days preceding such event
that are utilized under Section 6.1 with respect to periods straddling the date
of such event, so as to protect the rights of the Noteholders; provided that no
such adjustment shall increase the Conversion Price as otherwise determined
pursuant to this Section 6.

                 6.7.     Calculation of Conversion Price; Notices.

                          (i)     All calculations of the Conversion Price
under this Section 6 shall be computed to the nearest One-Thousandth (1/1000th)
of a cent.

                          (ii)    Immediately upon any adjustment of the
Conversion Price, the Company shall give written notice thereof to the
Noteholders, setting forth in reasonable detail and certifying the calculation
of such adjustment, provided however, that such notice shall not be deemed to
be conclusive as to the Conversion Price calculation.

                          (iii)   The Company shall give written notice to the
Noteholders at least thirty (30) days prior to the date on which the Company
closes its books or takes a record (A) with respect to any subdivision or
combination of the Common Stock that is subject to Section 6.4, or any other
dividend or distribution upon the Common Stock, (B) with respect to any pro
rata subscription offer to holders of Common Stock or (C) for determining
rights to vote with respect to any Organic Change, dissolution or liquidation.

                          (iv)    The Company shall also give written notice to
the Noteholders at least thirty (30) days prior to the date on which any
Organic Change, dissolution or liquidation shall take place.

                 6.8.     Excluded Transaction.  The provisions of this Section
6 shall not apply to the following transactions:  (i) the conversion of the
Notes and exercise of the Warrant, (ii) the issuance of shares of Common Stock
in the acquisition of the minority ownership interests in U.S.  Drug Testing,
Inc. and Good Ideas Enterprises, Inc. as previously disclosed to the public,
(iii) the acquisition of any Person engaged exclusively in, or engaged in a
business directly related to, the business of substance abuse testing, (iv)
conversion of shares of the Series A Preferred Stock of the Company (the
"Preferred Stock") outstanding as of the Effective Date, in accordance with the
terms of the Preferred Stock, (v) transactions that are subject to Section 15.2
or Section 15.3, (vi) Options granted or to be granted to officers of the
Company, not previously employed by the Company, as an inducement essential to
entering into a contract of employment with the Company provided that the total
number of shares of Common Stock subject to all such excluded Options that may
be outstanding at any one time shall not exceed Two Hundred Fifty Thousand
(250,000) shares of Common Stock, and (vii) the issuance of 200,000 shares of
Common Stock to John Sloan described in Section 8.2(c).

requisite corporate power and authority to own its properties and assets and to

each jurisdiction where failure to be so qualified would have a material
adverse effect on its financial condition, business, prospects or operations,
except that the Company is in the process of becoming qualified to do business
in the State of Florida.

                 8.2.     Capitalization.  The authorized capital stock of the
Company consists of the following:

                 (c)      Options, Warrants, Reserved Shares.  As of the

                          ranging from $1.0625 to $4.00.  Section 8.2(c) of the

                          the Warrant).  The Company has no obligation,
                          contingent or otherwise, to repurchase any shares of

                          The

                          agreement dated June 14, 1996 between the Company and
                          John Sloan.

the Other Transaction Documents each constitute a valid and binding obligation
of the Company enforceable in accordance with its and their terms, subject, as

and registrations, qualifications and filings with, any federal or state
governmental agency, authority or body, or any third party, required in
connection with the execution, delivery and, other than with respect to the
registration of the Underlying Common Stock, performance of this Agreement and
the Other Transaction Documents and the consummation of the transactions
contemplated hereby and thereby have been obtained.

                 8.5.     Valid Issuance of Stock. The outstanding shares of

applicable federal and state securities laws, including, without limitation,
anti-fraud provisions.

                 8.6.     Liabilities. The Company has no Indebtedness, which
ranks senior or pari pasu in right of payment to the Notes, that the Company
has directly or indirectly created, incurred, assumed, or guaranteed, or with

                 8.7.     Title to Properties and Assets.  The Company has good
and marketable title to its properties and assets held in each case subject to
no Lien of any kind.  With respect to the property and assets it leases, the
Company is in compliance with such leases and, to the best of the Company's
knowledge, the Company holds valid leasehold interests in such assets free of
any Liens, encumbrances, security interests or claims of any party other than
the lessors of such property and assets.

                 8.8.     Status of Proprietary Assets.

                          (a)     Ownership.  The Company and its Subsidiaries
have full title and ownership of, or have license to, all Proprietary Assets
set forth on Section 8.8(a) of the Disclosure Schedule.  Such Proprietary
Assets constitute all Proprietary Assets necessary to enable each of them to
carry on its business as now conducted and as presently proposed to be
conducted without any conflict with or infringement of the rights of others.
Except as specifically noted on Section 8.8(a) of the Disclosure Schedule, to
the best of the Company's knowledge, no third party has any ownership right,
title, interest, claim in or lien on any of the Company's or any of the
Company's Subsidiaries' Proprietary Assets and the Company has taken, and in
the future the Company will use its best efforts to take, and shall cause its
Subsidiaries to take, all steps reasonably necessary to preserve its and their
legal rights in, and the secrecy of, all its and their Proprietary Assets,
except those for which disclosure is required for legitimate business or legal
reasons.

                          (b)     Licenses; Other Agreements.  Except as
specifically noted on Section 8.8(b) of the Disclosure Schedule, neither the
Company nor any of its Subsidiaries have granted, and, to the best of the
Company's knowledge, there are not outstanding, any options, licenses or
agreements of any kind relating to any Proprietary Asset of the Company or any
of its Subsidiaries, nor is the Company or any of its Subsidiaries bound by or
a party to any option, license or agreement of any kind with respect to any of
its or their Proprietary Assets, as the case may be.  Except as specifically
noted on Section 8.8(b) of the Disclosure Schedule and except for the Company's
sublicenses and assignments to U.S. Drug Testing, Inc., neither the Company nor
any of its Subsidiaries is obligated to pay any royalties or other payments to
third parties with respect to the marketing, sale, distribution, manufacture,
license or use of any Proprietary Asset or any other property or rights.

                          (c)     No Infringement.  To the best of the
Company's knowledge, neither the Company nor any of its Subsidiaries has
violated or infringed, and is not currently violating or infringing, and
neither the Company nor any of its Subsidiaries has received any communications
alleging that the Company or any of its Subsidiaries (or any of its or their

proprietary computer programs, software, databases, trade secrets and
proprietary information of any other Person.

<PAGE>   22
                          (d)     No Breach by Employee.  The Company is not
aware that any employee or agent of, or consultant to, the Company or any of
its Subsidiaries is obligated under any agreement (including licenses,
covenants or commitments of any nature) or subject to any judgment, decree or
order of any court or administrative agency, or any other restriction that
would interfere with the use of his or her best efforts to carry out his or her
duties for the Company or such Subsidiary, as the case may be, or to promote
the interests of the Company or such Subsidiary, or that would conflict with
the Company's or any of the Company's Subsidiaries' business as proposed to be
conducted.  The carrying on of the Company's or any of the Company's
Subsidiaries' business by the employees and agents of or and consultants to the
Company or such Subsidiary, as the case may be, and the conduct of the
Company's or any of the Company's Subsidiaries' business as presently proposed,
will not, to the best of the Company's knowledge, conflict with or result in a
breach of the terms, conditions or provisions of, or constitute a default
under, any contract, covenant or instrument under which any of such employees
or agents of or consultants to the Company or any Subsidiary of the Company is
now obligated.  The Company does not believe it is or will be necessary to
utilize any inventions of any employees or agents of or consultants to the
Company or any of its Subsidiaries (or persons the Company or any of its
Subsidiaries currently intends to hire) made prior to their employment by the
Company or such Subsidiary, as the case may be.  Except as specifically noted
on Section 8.8(d) of the Disclosure Statement, to the best of the Company's
knowledge, at no time during the conception of or reduction of any of the
Company's or any of the Company's Subsidiaries' Proprietary Assets to practice
was any developer, inventor or other contributor to such patents operating
under any grants from any governmental entity or agency or private source,
performing research sponsored by any governmental entity or agency or private
source or subject to any employment agreement or invention assignment or
nondisclosure agreement or other obligation with any third party that could
adversely affect the Company's or such Subsidiary's rights in such Proprietary
Assets.

                 8.9.     Material Contracts and Obligations.  All agreements,
contracts, leases, licenses, instruments, commitments (oral or written),
indebtedness, liabilities and other obligations to which the Company is a party
or by which it is bound that are (a) material to the conduct or operations of
its business and properties; (b) involve any of the officers, consultants,
directors, employees or stockholders of the Company; (c) obligate the Company
to share, license or develop any product or technology; or (d) otherwise
required to be filed as exhibits to the Company's filings with the Securities
and Exchange Commission ("SEC") (any such agreement, contract, lease, license,
instrument, commitment (oral or written), indebtedness, liability and other
obligation, a "Material Contract") have been filed as exhibits to the Company's
filings with the SEC or are listed in Section 8.9 of the Disclosure Schedule
and have been made available for inspection by the Noteholders and its counsel.

                 8.10.    Litigation.  Except as set forth in Section 8.10 of
the Disclosure Schedule, there is no action, suit, proceeding, claim,
arbitration or investigation ("Action") pending and, to the best of the
Company's knowledge, no material Action currently threatened against the
Company, its activities, properties or assets.   To the best of the Company's
knowledge, there is no Action pending or currently threatened against any
officer, director or employee of the Company in connection with such officer's,
director's or employee's relationship with, or actions taken on behalf of, the

legal basis for any such Action that might result, individually or in the
aggregate, in any material adverse change in the business, properties, assets,
financial condition, affairs or prospects of the Company.  By way of example
but not by way of limitation, there are no Actions pending or, to the best of
the Company's knowledge, threatened (or any basis therefor known to the
Company) relating to the prior employment of any of the Company's employees or
consultants, their use in connection with the Company's business of any
information, technology or techniques allegedly proprietary to any of their
former employers, clients or other parties, or their obligations under any
agreements with prior employers, clients or other parties.  The Company is not
a party to or subject to the provisions of any order, writ, injunction,
judgment or decree of any court or government agency or instrumentality and
there is no Action by the Company currently pending or which the Company
intends to initiate.

                 8.11.    Governmental Consents.  Other than in connection with
the registration of the Underlying Common Stock, all consents, approvals,
orders, authorizations or registrations, qualifications, designations,
declarations or filings with any federal or state governmental authority on the
part of Company required in connection with the consummation of the
transactions contemplated herein shall have been obtained prior to and be
effective as of the Effective Date.

                 8.12.    Compliance with Other Instruments.  The Company is
not in, nor will the conduct of its business as proposed to be conducted result
in, any violation, breach or default of any term of the Company's Certificate
of Incorporation, as amended ("Certificate of Incorporation"), or the Company's
Bylaws (the "Bylaws") or in any term or provision of any Material Contract, or
of any provision of any foreign or domestic state or federal judgment, decree,
order, statute, rule or regulation applicable to or binding upon the Company.
The execution, delivery and performance of and compliance with this Agreement
and the consummation of the transactions contemplated hereby will not result in
any such violation or default, or be in conflict with or constitute, with or
without the passage of time or the giving of notice or both, either a default
under the Certificate of Incorporation or Bylaws, or any agreement or contract
of the Company, or a violation of any statutes, laws, regulations or orders, or
an event which results in the creation of any lien, charge or encumbrance upon
any asset of the Company.

                 8.13.    Disclosure.  No representation or warranty by the
Company in this Agreement or in any statement or certificate signed by any
officer of the Company furnished or to be furnished to the Noteholders pursuant
to this Agreement contains or will contain any untrue statement of a material
fact or omits or will omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances in which they are made, not misleading.  The Company's Form 10-K

disclose all of the Company's material debts, liabilities and obligations of
any nature, whether due or to become due, as of their respective dates
(including, without limitation, absolute liabilities, accrued liabilities, and
contingent liabilities) to the extent such debts, liabilities and obligations
are required to be disclosed in accordance with generally accepted accounting
principles.  The Company has good and marketable title to all assets set forth
on the balance sheets of the Financial Statements, except for such assets as
have been spent, sold or transferred in the ordinary course of business since
their respective dates.

                 8.17.    Certain Actions or Developments.  Since June 30,

S-K.  As of the Effective Date, no event has occurred that requires the
Prospectus to be supplemented or amended other than with respect to (i) the
transactions contemplated under this Agreement and (ii) amendments to disclose
options and warrants that have expired by their terms.

                 8.18.    Activities Since Year-End.  Except as disclosed in

                          covered by insurance, materially and adversely
                          affecting the assets, properties, financial
                          condition,





                                       16
<PAGE>   25
                          operating results, prospects or business of the
                          Company (as presently conducted and as presently
                          proposed to be conducted);

                 (b)      any waiver by the Company of a valuable right or of a
                          material debt owed to it;

                 (c)      any satisfaction or discharge of any lien, claim or
                          encumbrance or payment of any obligation by the
                          Company, except such a satisfaction, discharge or
                          payment made in the ordinary course of business that
                          is not material to the assets, properties, financial
                          condition, operating results or business of the
                          Company;

                          officer, director, consultant or agent that would be
                          required to be disclosed if a Form 10-K were to be
                          filed as of the Effective Date; or

                 (f)      to the Company's knowledge, any other event or
                          condition of any character which would materially and
                          adversely affect the assets, properties, financial
                          condition, operating results or business of the
                          Company.

                 8.19.    Tax Matters.  The provisions for taxes in the
Financial Statements are sufficient for the payment of all accrued and unpaid
federal, state, county and local taxes of the Company, whether or not assessed
or disputed as of the date of each such balance sheet.  There have been no
examinations or audits of any tax returns or reports by any applicable federal,
state or local governmental agency.  The Company has duly filed all federal,
state, county and local tax returns required to have been filed by it and paid
all taxes shown to be due on such returns.  There are in effect no waivers of
applicable statutes of limitations with respect to taxes for any year.

                 8.20.    Tax Elections.  The Company has not elected pursuant
to the Internal Revenue Code of 1986, as amended (the "Code"), to be treated as
an "S" corporation or a collapsible corporation pursuant to Section 341(f) or
Section 1362(a) of the Code, nor has it made any other elections pursuant to
the Code (other than elections which relate solely to matters of accounting,
depreciation or amortization) which would have a material affect on the
Company, its financial condition, its business as presently conducted or
presently proposed to be conducted or any of its properties or material assets.

                 8.21.    Environmental Matters.  During the period that the
Company has owned or leased its properties and facilities, (a) there have been
no disposals, releases or threatened releases of Hazardous Materials (as

Company nor, to the Company's knowledge, any third party, has used, generated,
manufactured or stored on, under or about such properties or facilities or
transported to or from such properties or facilities any Hazardous Materials.
The Company has no knowledge of any presence, disposals, releases or threatened
releases of Hazardous Materials on, from or under any





                                       17
<PAGE>   26
of such properties or facilities, which may have occurred prior to the Company
having taken possession of any of such properties or facilities.  For purposes
of this Agreement, the terms "disposal", "release", and "threatened release"
shall have the definitions assigned thereto by the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, 42 U.S.C. Section 9601 et
seq., as amended ("CERCLA").  For the purposes of this Section, "Hazardous
Materials" shall mean any hazardous or toxic substance, material or waste which

         9.      REPRESENTATIONS AND WARRANTIES OF THE NOTEHOLDERS.  Each of
the Noteholders represents and warrants to the Company as follows:

                 9.1.     Purchase for Own Account; Investment Intent.  The
Warrant and the Notes have been acquired for the Noteholders' own account, not
as a nominee or agent, and not with a view to or in connection with the sale or
distribution of any part thereof, other than pursuant to a transaction, or
series of transactions, registered or exempt from registration under the
Securities Act.

                 9.2      Current Ownership.  As of the Effective Date, the
Noteholders own approximately Two Million Three Hundred Thousand (2,300,000)
shares of Common Stock (the "Owned Shares").

         10.     REGISTRATION.

                 10.1     Company's Obligations.  Promptly after the Effective
Date, the Company shall file a registration statement with the SEC under the
Securities Act registering the Company's offer and sale of the Underlying
Common Stock and the Company shall use its best efforts to have the SEC declare
effective such registration statement within three (3) months after the
Effective Date.  The Company shall similarly register the Company's offer and
sale of the Underlying Common Stock under any applicable state securities laws.
So long as any portion of the Outstanding Balance remains outstanding or the
Warrant remains outstanding, the Company shall file such amendments and/or
supplements to any registration statement under the Securities Act or under any
state securities laws covering the Company's offer and sale of such Underlying
Common Stock and supplement and keep current any prospectus forming a part of
such registration statement as may be necessary to permit the Company to
deliver to a Noteholder upon any sale by the Company of the Underlying Common
Stock a prospectus meeting the requirements of the Securities Act and the
regulations of the SEC thereunder, and as may be necessary to comply with any
applicable state securities laws.  The shares of Common Stock issuable under
this Agreement are subject to a Registration Rights Agreement dated November 8,
1996 with the Company.

<PAGE>   27
                 10.2     Remedies.  In the event that, within three (3) months
after the Effective Date, the Company has not file a registration statement for
the Underlying Common Stock and has not used its best efforts to have the SEC
declare effective such registration statement, or if at any time after such
registration statement is declared effective a period of more than thirty (30)
days passes during which such registration statement (or a successor
registration statement) is not effective, or during which the prospectus under
any such registration statement does not meet the requirements of the
Securities Act, the Company shall pay the Noteholders a cash penalty in an
amount equal to ten percent (10%) of the Outstanding Amount; provided that the
Noteholders shall have cooperated in providing information regarding their
intended plan of distribution if and to the extent that such information is
requested by the SEC.

         11.     COVENANTS OF THE COMPANY.

         The Company covenants to the Noteholders as follows:

proceeds from the Loan in substantially the amounts indicated for the purposes
set forth on Exhibit D.

                 11.2     Seniority.  The Company shall not, directly or
indirectly, create, incur, issue, assume or become liable with respect to or
become responsible for, contingently or otherwise, any Indebtedness which ranks
senior or pari pasu in right of payment to the Notes; provided that
notwithstanding the foregoing the Company may create, incur, issue, assume,
become liable or suffer to exist Indebtedness under capitalized leases not
exceeding $750,000 in the aggregate, which capitalized leases may rank pari
pasu, but not senior, to the Notes.

                 11.3     Note Restrictive Covenants.  So long as any portion
of the Outstanding Balance under the Notes remains outstanding, the Company
shall not, without the prior written consent of the Noteholders:

         provisions, or enter into any agreement, arrangement or understanding,
         which would adversely affect or otherwise impair the rights or
         relative priority of the Noteholders under this Agreement, the
         Articles of Incorporation or the Bylaws; or

                          (xxi)   enter into any transaction or series of
         related transactions not otherwise permitted under this Section 11.3,
         the aggregate value of the consideration for which exceeds One Million
         Dollars ($1,000,000).

                 11.4     Note Affirmative Covenants.  So long as any portion
of the Outstanding Balance under the Notes remains outstanding, the Company

written consent of the Noteholders:

                          (i)     at all times cause to be done all things
         necessary to maintain, preserve and renew its corporate existence and

         its businesses;

                          (ii)    maintain and keep its material properties in
         good repair, working order and condition, and from time to time make

         material respects at all times;

                          (iii)   pay and discharge when payable all taxes,
         assessments and governmental charges imposed upon its properties or
         upon the income or profits therefrom (in each case before the same
         becomes delinquent and before penalties accrue thereon) and all claims
         for labor, materials or supplies which if unpaid would by law become a
         Lien upon any of its property, unless and to the extent that the same
         are being contested in good faith and by appropriate proceedings and
         adequate reserves (as determined in accordance with generally accepted
         accounting principles, consistently applied) have been established on
         its books with respect thereto;

                          (iv)    comply with all other obligations which it
         incurs pursuant to any contract or agreement, whether oral or written,
         express or implied, as such obligations become due, unless and to the

         appropriate proceedings and adequate reserves (as determined in
         accordance with generally accepted accounting principles, consistently
         applied) have been established on its books with respect thereto;

                          (v)     comply with all applicable laws, rules and
         regulations of all governmental authorities;

                          (vi)    apply for and continue in force with good and
         responsible insurance companies adequate insurance covering risks of

                                       22
<PAGE>   31
         customary for well-insured corporations of similar size engaged in
         similar lines of business; and

                          (vii)   maintain proper books of record and account
         which present fairly in all material respects its financial condition
         and results of operations and make provisions on its financial
         statements for all such proper reserves as in each case are required
         in accordance with generally accepted accounting principles,
         consistently applied.

                 11.5     Nothing in this Section 11, express or implied, is
intended to confer any rights or remedies under or by reason of this Section 11
upon any Person other than a holder of a Note under which any portion of the
Outstanding Balance remains outstanding.

         12.     RESTRICTIONS ON OPEN MARKET SALES OF THE OWNED SHARES.  After
the Effective Date, the Noteholders may sell One Million (1,000,000) of the
Owned Shares in Open Market Transactions without regard to any of the
limitations set forth in this Section 12.  After the Noteholders have sold One
Million (1,000,000) of the Owned Shares in Open Market Transactions pursuant to
the immediately preceding sentence, the Noteholders shall not sell any of the
remaining Owned Shares on Open Market Transactions unless: (i) the sales price
for such shares (before any fees or commissions) is equal to or greater than
the Limit Price (as defined below), (ii) the volume of shares sold by the
Noteholders on any trading day at a price below the Limit Price (before any
fees or commissions) does not exceed twenty-five percent (25%) of the average
daily trading volume of Common Stock reported for the five trading days
immediately preceding the date of such sale, provided that any sales by the
Noteholders during the immediately preceding five trading days at a price below
the Limit Price shall be excluded from the calculation of the average daily
trading volume, or (iii) such shares are sold at the best offer price.  For
purposes of this Section 12, the term "Open Market Transactions" shall mean any
transaction that is reported under a transaction reporting plan other than (A)
a block trade (as that term is defined under Exchange Act Rule 10b-18) or (B) a
transaction that is not reported on the consolidated quotation system.  For
purposes of this Section 12, the term "Limit Price" shall mean Two Dollars
($2.00) unless and until adjusted pursuant to Section 6.4 and 6.6.  This
Section 12 shall not limit in any way the ability of the Noteholders to sell
the Owned Shares in transactions that are not Open Market Transactions.

         13.     DEFAULT.

                 13.1     Event of Default.  For purposes of this Agreement,
the term "default" shall include any of the following:

under the Notes when due or to pay the Outstanding Balance on the Maturity
Date;

                          (b)     In excess of Fifty Thousand Dollars ($50,000)

breach of any agreement for Indebtedness, including but not limited to loan
agreements, or material breach under any real property lease agreements and
capital equipment lease agreements, by which Company is bound or obligated;





                                       23
<PAGE>   32
                          (c)     The filing of a petition in bankruptcy or
under any similar insolvency law by the Company, the making of an assignment
for the benefit of creditors, or if any voluntary petition in bankruptcy or
under any similar insolvency law is filed against the Company and such petition
is not dismissed within sixty (60) days after the filing thereof.

                          (d)     The Company breaches any of its obligations
and covenants set forth in this Agreement other than as described in Section
13(a) above, or breaches any Other Transaction Documents with the Noteholders
or their Affiliates;

                          (e)     The shares of Common Stock cease to be traded
on any national securities exchange or cease to be quoted on the Nasdaq

                          (f)     Any trade payable that is not being contested
in good faith remains delinquent for more than sixty (60) days.

                 13.2     Financial Defaults.  Upon any defaults of the Company
under Sections 13(a), (b) and (c), the Noteholders shall at their sole and
exclusive option be entitled to any or all of the following remedies:

                                  within 30-days after notice of such default
                                  has been delivered by the Noteholders to the
                                  Company, acceleration of repayment of the
                                  Outstanding Balance in which case the
                                  Outstanding Balance and all interest accrued
                                  thereon shall be due and payable immediately;
                                  and/or

                          (ii)    the rate of interest applicable hereunder and
                                  under the Notes shall be increased as of the
                                  date of notice of such default to twelve
                                  percent (12%) per annum until such default
                                  has been cured or waived.

                 13.3     Other Defaults.  Upon any defaults of the Company
under Sections 13(d) and (e), the Noteholders shall at their sole and exclusive
option be entitled to any or all of the following remedies:

                          (i)     in the event such default has not been cured
                                  within 30-days after notice of such default
                                  has been delivered by the Noteholders to the
                                  Company, acceleration of repayment of the
                                  Outstanding Balance in which case the
                                  Outstanding Balance and all interest accrued
                                  thereon shall be due and payable immediately;

                                  increased as of the date of notice of such
                                  default to ten percent (10%) per annum until

                 13.4     Additional Remedies.  In addition, upon any default
of the Company hereunder:

                          (i)     The Noteholders shall have full recourse
                                  against any tangible or intangible assets of
                                  the Company and may pursue any legal or
                                  equitable remedies that it has available to

                          (ii)    shall have a full right of offset for any
                                  amounts due upon such a default against any
                                  amounts payable by the Noteholders to the
                                  Company.

                 13.5     Notice of Defaults.  The Company shall promptly
notify the Noteholders of any defaults under this Agreement that the Company
has knowledge of or after reasonable investigation should have had knowledge

         14.     INFORMATION, INSPECTION & BOARD REPRESENTATION AND BOARD
OBSERVER RIGHTS.

                 14.1.    Information Rights.  So long as any portion of the
Outstanding Balance under the Notes remains outstanding, the Company shall
deliver to the Noteholders or the holder of any securities issued (directly or
indirectly) upon conversion thereof copies of the Company's Forms 10-K, 10-Q
and 8-K and the Company's Annual Reports to Stockholders and definitive proxy
statement promptly after such documents are filed with the SEC.

                 14.2     Inspection Rights.  So long as any portion of the
Outstanding Balance under the Notes remains outstanding, any of the Noteholders
and any Person any of the Noteholders may designate as agent shall have the
right to review all books and records, reports, accounts and other financial
documents of the Company and to copy the same and to make excerpts therefrom,
all at such reasonable times and as often as any of the Noteholders may
reasonably request, upon prior written notice to the Company, so long as such
review and copying does not unreasonably interfere with the business of the
Company and such Noteholder and agent agrees to keep confidential, and not
disclose, except as may be required by law or court order, all information
obtained during such review of a confidential or proprietary nature (and not
otherwise known to the Noteholders through other sources or publicly known).

                 14.3.    Board Representation and Observer Rights.  So long as
any portion of the Outstanding Balance under the Notes remains outstanding and
thereafter until the earlier of the fifth anniversary of the Effective Date and
the date that the Noteholders cease to hold at least twenty-five percent (25%)
of the Common Stock into which the Notes are convertible, the Noteholders shall
be entitled to either (i) designate one individual to be a director on the
Company's Board of Directors, and the Company shall use its best efforts to
have such individual designated by the Noteholders appointed, elected and
maintained as a director on the Company's Board of Directors; or (ii) appoint a
representative to attend and observe meetings of the Board of Directors of the
Company and any committee thereof.

         15.     PARTICIPATION RIGHTS.





                                       25
<PAGE>   34
                 15.1     Participation Rights.  If at any time while any
portion of the Outstanding Balance under the Notes remains outstanding, the
Company grants, issues or sells any Common Stock, Option, Convertible
Securities or rights to purchase stock, warrants, securities or other property
(the "Purchase Rights") pro rata to the record holders of any class of Common
Stock, then each Noteholder shall be entitled to acquire, upon the terms
applicable to such Purchase Rights, the aggregate Purchase Rights which such
holder could have acquired if such holder had held the number of shares of
Common Stock acquirable upon complete conversion of the Note immediately before
the date on which a record is taken for the grant, issuance or sale of such
Purchase Rights, or, if no such record is taken, the date as of which the
record holders of Common Stock are to be determined for the grant, issue or
sale of such Purchase Rights.

                 15.2     Rights to Purchase.  If at any time while any portion
of the Outstanding Balance under the Notes remains outstanding, the Company
grants, issues or sells any Common Stock, Options, Convertible Securities or
other Purchase Rights which issuance reduces either the percentage voting or
equity interest of the Noteholders in the Company (based on the number of
shares of Common Stock previously acquired by them under the Notes or Warrants,
or that could be acquired upon complete conversion of all Notes and exercise in
full of the Warrants held by them) and which are not subject to Section 15.1,
then each Noteholder shall have the right to purchase from the Company for
cash, upon the same terms and conditions as such equity securities are sold to
other investors, at the price per share at which such equity securities were
sold (based on the net proceeds to the Company calculated under the procedures
described in Section 6) that number of shares of such equity securities which,
if purchased by the Noteholder, would result in the Noteholder retaining the
percentage voting or equity interest in the Company held by the Noteholder
immediately prior to such reduction of the Noteholder's interest (based on the
number of shares of Common Stock previously acquired by them under the Notes or
Warrants, or that could be acquired upon complete conversion of all Notes and
exercise in full of the Warrants held by them); provided, however, that this
Section 15.2 shall apply only to issuances in connection with a capital raising
transaction effected as a public offering or a transaction or series of
transactions that is exempt from or otherwise not subject to the Securities
Act; but in no case shall this Section 15.2 apply to a transaction subject to
Section 6.

                 15.3     Option Rights.  If at any time while any portion of
the Outstanding Balance under the Notes remains outstanding directors of the
Company are granted Common Stock, Options or Convertible Securities as part of
their retainer, then the Noteholders shall likewise be granted in the aggregate
an identical number of shares of Common Stock, Options or Convertible
Securities on the same terms and at the same time as those granted to a
director, provided that any restrictions on the grant, vesting, exercisability
or expiration of Options granted to directors shall not be applicable to the
Options granted to the Noteholders under this Section 15.3.

         16.     RSA NOTES.  The conversion of the principal and due but unpaid
interest under the RSA Notes into Common Stock at a rate  based on the Market
Price of Common Stock on the date of such conversion and the application of
principal and due but unpaid interest under the RSA Notes to exercise warrants
held by payees under the RSA Notes shall not constitute a breach of a
representation or warranty or a violation of a covenant by the Company under
this Agreement or trigger the provisions of Section 6 or Section 15.

the other party for review and comment a reasonable time prior to public
disclosure.

                 17.15.   Appraisal Remedy.  In case of any dispute as to
valuation of a security under this Agreement, the fair value of such security
shall be determined by an appraiser without any discount for liquidity or
restrictions under the Securities Act.  This appraisal process shall be
instituted within fourteen (14) days after a party to this Agreement notifies
the other party of its desire to submit the issue to an appraiser.  In the
event the parties do not agree on an appraiser within seven (7) days after a
party to this Agreement notifies the other party of its desire to submit the
issue to an appraiser, the fair value of such security shall be determined,
without any discount for liquidity or restrictions under the Securities Act, by
the majority determination of a panel of three (3) appraisers who shall be
selected in the following manner:  the Company shall select one (1) appraiser
and the Noteholders shall jointly select one (1) appraiser and the two (2)
appraisers selected by the Company and the Noteholders shall jointly select a
third appraiser.  The appraiser selected jointly by the parties and, if
applicable, each member of the appraisal panel shall be an individual who
personally and whose Affiliates shall not have a previous business relationship
with either party.  The appraiser and, if applicable, the appraisal panel shall
endeavor to complete the appraisal as soon as practicable.  The determination
of such appraiser and , if applicable, the appraisal panel shall be final and
binding on the Company and the Noteholders, and the fees and expenses of such
appraisal shall be borne equally by the Company, on the one hand, and the
Noteholders, on the other.

                                   EXHIBIT A

                         REGISTRATION RIGHTS AGREEMENT

          THIS REGISTRATION RIGHTS AGREEMENT is made as of the 8th day of
November 1996 (the "Effective Date"), by and between Substance Abuse
Technologies, Inc., a Delaware corporation (the "Company"), on the one hand,
and on the other hand, S.A.C. Capital Associates, LLC, an Anguilla limited
liability company, and Steven A. Cohen (together, the "Stockholders").

                                    RECITALS

         WHEREAS, the Company and the Stockholders are parties to a Convertible
Loan and Warrant Agreement, dated November 8, 1996 (the "Note Agreement"),
pursuant to which the Company issued Convertible Notes and Warrants to the
Stockholders;

         WHEREAS, the Stockholders may acquire shares of the Common Stock of
the Company, $0.01 par value (the "Common Stock"), under the Convertible Notes
and the Warrants; and

         WHEREAS, the Note Agreement provides that the Company shall extend
certain registration rights to the Stockholders;

         NOW, THEREFORE, the parties hereby agrees as follows:

         1.      Registration Rights. The Company covenants and agrees as
follows:

                 1.1      Definitions.  For purposes of this Agreement:

                 (a)      The term "register", "registered", and "registration"
refer to a registration affected by preparing and filing a registration
statement or similar document in compliance with the Securities Act of 1933, as
amended (the "Act"), and the use, by the Company, of its best efforts to cause
the declaration or ordering of effectiveness of such registration statement or
document.

                 (b)      The term "Underlying Common Stock" means (1) any of
the shares of Common Stock issued pursuant to the Note Agreement, upon
conversion of the Convertible Notes and/or upon exercise of the Warrants, and
(2) any shares of the Common Stock of the Company issued as (or issuable upon
the conversion or exercise of any warrant, right or other security which is
issued as) a dividend or other distribution with respect to, or in exchange for
or in replacement of, the shares of Common Stock issued or issuable under the
Convertible Notes and the Warrants, excluding in all cases, however, any
Underlying Common Stock sold by a person in a transaction in which his, her or
its rights under this Section 1 are not assigned.

                 (c)      The term "Holder" means any person owning or having
the right to acquire Underlying Common Stock or any assignee thereof in
accordance with Section 1.10 hereof.





                                      E-1

                 1.2      Company Registration.

                 (a)      Piggyback Registration Rights.  If, at any time after
the Effective Date (but without any obligation to do so), the Company proposes
to register (including for this purpose a registration effected by the Company
for stockholders other than the Holders) any of its stock or other securities
under the Act in connection with the public offering of such securities solely
for cash (other than a registration statement or Form S-8 or Form S-4 or any
successor form thereto), the Company shall, at such time, promptly give each
Holder written notice of such registration. The Company shall, subject to the
provisions of Section 1.8, cause to be registered under the Act all of the
Underlying Common Stock owned by each Holder to be registered under the Act
under the proposed registration statement unless within twenty (20) days after
the mailing of the notice by the Company a Holder gives the Company written
notice in accordance with Section 2.5 that he does not want all or a portion of
the Underlying Common Stock held by him to be so registered.

                 (b)      Demand Registration Rights.  In the event that any of
the Underlying Common Stock, when issued to a Holder, are "restricted
securities" as defined in Rule 144 under the Act (or in any successor rule),
the Holders may demand that the Company register under the Act, all or a
portion of the Underlying Common Stock owned by the Holders. Such demand may
only be made one time in the aggregate for all of the Holders.

                 1.3      Obligations of the Company. Whenever undertaking
under this Section 1 to effect the registration of any Underlying Common Stock,
the Company shall, as expeditiously as reasonably possible:

                 (a)      Prepare and file with the Commission a registration
statement with respect to such Underlying Common Stock and use its best efforts
to cause such registration statement to become effective and keep such
registration statement effective for one hundred eighty (180) days or such
shorter period as requested by the Holders of a majority of the Underlying
Common Stock registered thereunder.

                 (b)      Prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Act with respect to the disposition of all securities
covered by such registration statement.

                 (c)      Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Underlying Common Stock owned
by them.

                 (d)      Use its best efforts to register and qualify the
securities covered by such registration statement under any applicable rule of
an exchange or Nasdaq and under such other securities or Blue Sky laws of the
States of Florida, California, Connecticut and New York, provided that the
Company shall not be required in connection therewith or as a condition thereto
to qualify to do business or to file a general consent to service of process in
any such states or jurisdictions.





                                      E-2
<PAGE>   41
                 (e)      In the event that an underwritten public offering is
utilized under the registration described in Section 1.2(a) or is demanded for
the registration described in Section 1.2(b), include the Underlying Common
Stock in such underwritten public offering and enter into and perform its
obligations under an underwriting agreement, in usual and customary form, with
the managing underwriter of such offering. Each Holder participating in such
underwriting shall also enter into and perform its obligations under such an
agreement.

                 (f)      Notify each Holder of the Underlying Common Stock
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

                 (g)      Furnish, at the request of any Holder requesting
registration of Underlying Common Stock pursuant to this Section 1, on the date
that such Underlying Common Stock are delivered to the underwriters for sale in
connection with a registration pursuant to this Section 1, if such securities
are being sold through underwriters, or, if such securities are not being sold
through underwriters, on the date that the registration statement with respect
to such securities becomes effective, (i) an opinion, dated such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of the Underlying Common Stock and (ii) a letter dated such date,
from the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants
to underwriters in an underwritten public offering, addressed to the
underwriters, if any, and to the Holders requesting registration of the
Underlying Common Stock.

                 1.4      Furnish Information. It shall be a condition
precedent to the obligations of the Company to take any action pursuant to this
Section 1 with respect to the Underlying Common Stock of any selling Holder
that such Holder shall furnish to the Company such information regarding
itself, the Underlying Common Stock held by it, and the intended method of
disposition of such securities as shall be required to effect the registration
of such Holder's Underlying Common Stock.

                 1.5      Expenses of Registration. The Company shall bear and
pay all expenses incurred in connection with any registration, filing or
qualification, to the extent set forth in Section 1.3, of the Underlying Common
Stock with respect to the first registration pursuant to Section 1.2 for each
Holder (which right may be assigned as provided in Section 1.10), including
(without limitation) all registration, filing, and qualification fees, printers
and accounting fees relating or apportionable thereto, but excluding
underwriting discounts and commissions relating to Underlying Common Stock.

                 1.6      Underwriting Requirements. In connection with any
offering involving an underwriting of shares of the Company's capital stock,
the Company shall not be required under Section 1.2 to include any of the
Holders' securities in such underwriting unless they accept the





                                      E-3
<PAGE>   42
terms of the underwriting as agreed upon between the Company and the
underwriters selected by it (or by other persons entitled to select the
underwriters), and then only in such quantity as the underwriters determine in
good faith will not, jeopardize the success of the offering by the Company. If
the total amount of securities, including Underlying Common Stock, requested by
shareholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Underlying Common Stock, which the underwriters determine
in good faith will not jeopardize the success of the offering (the securities
so included to be apportioned pro rata among the selling shareholders according
to the total amount of securities entitled to be included therein owned by each
selling shareholder or in such other proportions as shall mutually be agreed to
by such selling shareholders). For purposes of the preceding parenthetical
concerning apportionment, for any selling shareholder which is a holder of
Underlying Common Stock and which is a partnership or corporation, the
partners, retired partners and shareholders of such holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons shall be deemed to be a single "selling
shareholder", and any pro rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder", as defined in this sentence.

                 1.7      Delay of Registration. No Holder shall have any right
to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

                 1.8      Indemnification. In the event any Underlying Common
Stock are included in a registration statement under this Section 1:

                 (a)      To the extent permitted by law, the Company will
indemnify and hold harmless each Holder who is not a director or executive
officer of the Company, any underwriter (as defined in the Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the
"1934 Act"), against any losses, claims, damages, or liabilities (joint or
several) to which they may become subject under the Act, or the 1934 Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"): (i) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) 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, or (iii) any violation or alleged violation
by the Company of the Act, the 1934 Act, any state securities law or any rule
or regulation promulgated under the Act, or the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person, as incurred, any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 1.8(a) shall not apply to amounts paid
in settlement of any such loss,





                                      E-4
<PAGE>   43
claim, damage, liability, or action if such settlement is effected without the
consent of the Company, nor shall the Company be liable in any such case for
any such loss, claim, damage, liability, or action to the extent that it arises
out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person.

                 (b)      To the extent permitted by law, each selling Holder
will indemnify and hold harmless the Company, each of its directors, each of
its officers who has signed the registration statement, each person, if any,
who controls the Company within the meaning of the Act, any underwriter, any
other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the
foregoing persons may become subject, under the Act, or the 1934 Act or other
federal or state law, insofar as such losses, claims, damages or liabilities
(or actions in respect thereto) arise out of or are based upon any violation,
in each case to the extent (and only to the extent) that such Violation occurs
in reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will pay, as incurred, any legal or other expenses reasonably incurred
by any person intended to be indemnified pursuant to this subsection 1.8(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.8(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder.

                 (c)      Promptly after receipt by an indemnified party under
this Section 1.8 of notice of the commencement of any action (including any
governmental action) such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.7, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by
such counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.8, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.8.

                 (d)      If the indemnification provided for in this Section
1.8 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or
expense referred to therein, then the indemnifying party, in lieu of
indemnifying such indemnified party hereunder, shall contribute to the amount
paid or payable by such indemnified party as a result of such loss, liability,
claim, damage, or expense in such proportion





                                      E-5
<PAGE>   44
as is appropriate to reflect the relative fault of the indemnifying party on
the one hand and of the indemnified party on the other in connection with the
statements or omissions that resulted in such loss, liability, claim, damage,
or expense as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

                 (e)      Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                 (f)      The obligations of the Company and Holders under this
Section 1.8 shall survive the completion of any offering of Underlying Common
Stock in a registration statement under this Section 1, and otherwise.

                 1.9      Reports Under Securities Exchange Act of 1934. With a
view to making available to the Holders the benefits of Rule 144 promulgated
under the Act and any other rule or regulation of the Commission that may at
any time permit a Holder to sell securities of the Company to the public
without registration, the Company agrees to:

                 (a)      make and keep public information available, as those
terms are understood and defined in Commission Rule 144 promulgated under the
Act;

                 (b)      file with the Commission in a timely manner all
reports and other documents required of the Company under the Act and the 1934
Act; and

                 (c)      furnish to any Holder, so long as the Holder owns any
Underlying Common Stock, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144
promulgated under the Act and the 1934 Act (at any time after it has become
subject to such reporting requirements), (ii) a copy of the most recent annual
and quarterly reports of the Company and such other report and documents so
filed by the Company, and (iii) such other information as may be reasonably
requested in availing any Holder of any rule or regulation of the Commission
which permits the selling of any such securities without registration.

                 1.10     Assignment of Registration Rights. The rights to
cause the Company to register Underlying Common Stock pursuant to this Section
1 may be assigned (but only with all related obligations) by a Holder to a
transferee or assignee of such securities, provided the Company is, within a
reasonable time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned; and provided, further, that
such assignment shall be effective only if immediately following such transfer
the further disposition of such securities by the transferee or assignee is
restricted or subject to volume limitations under the Act.





                                      E-6
<PAGE>   45
                 1.11     Termination of Registration Rights. No Holder shall
be entitled to exercise any right provided for in this Section 1 after November
6, 2002; provided that at least two registration statements of the Company have
been declared effective prior to such date with respect to which the Holders
are entitled to exercise the rights provided for in this Section 1.

         2.      Miscellaneous.

                 2.1      Successors and Assigns. Except as otherwise provided
herein, the terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective successors and assigns of the parties
(including transferees of the Notes, the Underlying Common Stock or any shares
issued or issuable upon the exercise of the Warrants). Nothing in this
Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or their respective successors and assigns any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

                 2.2      Governing Law. This Agreement shall be governed by
and construed under the laws of the State of New York.

                 2.3      Counterparts. This Agreement may be executed in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

                 2.4      Titles and Subtitles. The titles and subtitles used
in this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

                 2.5      Notices. Unless otherwise provided, any notice
required or permitted under this Agreement shall be given in writing and shall
be deemed effectively given upon personal delivery to the party to be notified
or upon deposit with the United States Post Office, by registered or certified
mail, postage prepaid or upon deposit with an express courier, addressed to the
party to be notified at the address indicated for such party on the signature
page hereof, or at such other address as such party may designate by ten (1)
days advance written notice to the other parties.

                 2.6      Expenses. If any action at law or in equity is
necessary to enforce or interpret the terms of this Agreement, the prevailing
party shall be entitled to reasonable attorneys' fees, costs and necessary
disbursements in addition to any other relief to which such party may be
entitled.

                 2.7      Amendments and Waivers. The Company and Holders of
50% of the Underlying Common Stock (to the extent issued and outstanding) and
of Notes representing 50% of the Outstanding Balance (to the extent issued and
outstanding) (as defined in the Note Agreement) can agree to an amendment of,
or a waiver to, the terms of this Agreement.

                 2.8      Severability. If one or more provisions of this
Agreement are held to be unenforceable under applicable law, such provision
shall be excluded from this Agreement and the balance of the Agreement shall be
interpreted as if such provision were so excluded and shall be enforceable in
accordance with its terms.

Outstanding Balance in quarterly installments with each installment due and
payable on March 15, June 15, September 15 and December 15 (or the first

option of Lender as set forth in the Purchase Agreement.  Following any such
acceleration, Lender shall have the rights and remedies set forth under the
Purchase Agreement.

         4.      Default.  Debtor will be deemed to be in default hereunder
upon any default under this Note, the Other Note or the Purchase Agreement and
thereafter Lender shall be entitled to exercise all rights and remedies
provided for herein, under the Purchase Agreement and by law or equity.  Any
default under this Note is subject to the terms of the Purchase Agreement.

         5.      Miscellaneous.

of any security given from time to time for this Note (if any), or other cause

accruing to Lender, upon any breach or default of any party hereto under this

or an acquiescence therein, or of any similar breach or default thereafter
occurring; nor shall any waiver of any other breach or default theretofore or
thereafter occurring.  Any waiver, permit, consent or approval of any kind or
character on the part of Lender of any breach or default under this Note or the

be effective only to the extent specifically set forth in such writing.  All
remedies, either under this Note, the Purchase Agreement, or by law or
otherwise, afforded to Lender shall be cumulative and concurrent, and shall not

shall not be deemed to be a waiver of the right to require prompt payment when
due of any other amounts then or thereafter due and payable.

         (c)     Time is of the essence hereof.

         (d)     The remedies of Lender as provided herein and in the Purchase

attorney or if suit is brought to collect or interpret this Note or any part
hereof or to enforce or protect any rights conferred upon Lender by this Note
or any other document evidencing or securing this Note, then Debtor promises
and agrees to pay all costs, including reasonable attorneys' fees, incurred by
Lender.

         (f)     If any provisions of this Note would require Debtor to pay
interest hereon at a rate exceeding the highest rate allowed by applicable law,
Debtor shall instead pay interest under this Note at the highest rate permitted
by applicable law.

         (g)     This Note and the rights and obligations herein (including
those under the Purchase Agreement) may not be assigned by Lender to a Person
other than an Affiliate without the advance written consent of Debtor which
consent may be withheld in the Company's sole and





                                      E-10
<PAGE>   49
absolute discretion.  This Note and the rights and obligations herein may not
be assigned by Debtor without the advance written consent of Lender.

         (h)     Any term of this Note may be amended only with the written
consent of Lender.

         (i)     The shares of Common Stock issuable under this Note are
subject to a Registration Rights Agreement with the Debtor dated November 8,
1996.

         (j)     This Note shall be governed in all respects by and construed
in accordance with the laws of the State of New York without regard to

2.       EXERCISE

         2.1     Exercise Period.  The Warrants shall not be exercisable in
whole or in part until the Commencement Date.  On and after the Commencement
Date, the Warrant shall be exercisable only to the extent that the number of
shares of Common Stock that the Registered Holder is deemed to beneficially own
as a result of the Warrant, when added to the number of shares of Common Stock
otherwise beneficially owned by the Registered Holder, does not result in the
Registered Holder being deemed the beneficial owner of greater than ten percent
(10%) of shares of Common Stock, all as determined under Rule 16a-1(a)(1) under
the Securities Exchange Act of 1934, as amended, or any successor rule.
Notwithstanding the immediately preceding sentence, except as provided in
Section 4.1 of this Warrant, the Warrant shall be fully exercisable at any time
during the 30-day period immediately prior to the Expiration Date.

         2.2     Exercise Procedure.

         (i)     This Warrant shall be deemed to have been exercised when the
Company has received all of the following items:

                 (a)      an Election to Purchase in the form attached hereto
         as Exhibit A, properly completed and executed by the Person (the
         "Purchaser") exercising all or part of the purchase rights represented
         by this Warrant;

                 (b)      this Warrant;

                 (c)      if this Warrant is not registered in the name of the
         Purchaser, an Assignment or Assignments in the form set forth in
         Exhibit B  hereto evidencing the assignment of this Warrant to the
         Purchaser, in which case the Registered Holder shall have complied
         with the provisions set forth in Section 7.1 hereof; and

                 (d)      either (1) a check or wire transfer payable to the
         Company in an amount equal to the product of the Purchase Price
         multiplied by the number of shares of Common Stock being purchased
         upon such exercise (the "Aggregate Exercise Price"), (2) a written
         notice to the Company that the Purchaser is exercising the Warrant (or
         a portion thereof) by authorizing the Company to withhold from
         issuance a number of shares of Common Stock issuable upon such
         exercise of the Warrant which when multiplied by the Market Price of
         Common Stock is equal to the Aggregate Exercise Price (and such
         withheld shares of Common Stock shall no longer be issuable under this
         Warrant), provided that the Purchase Price may be paid under the
         foregoing Section 2.2(i)(d)(2) only in the event that either (A) the
         SEC (or any applicable state) has not declared effective the
         registration statement described under Section 6 hereof by the
         Commencement Date, or (B) the Company has failed to file such
         amendments and/or supplements to any such registration statement
         covering the Company's offer and sale of the Underlying Common Stock
         or to supplement and keep current any prospectus forming a part of
         such registration statement as may be necessary to permit the Company
         to deliver to a Registered Holder upon any sale by the Company of the
         Underlying Common Stock a prospectus meeting the requirements of the
         Securities Act of 1933, as amended (the "Securities Act") and the





                                      E-14
<PAGE>   53
         regulations of the SEC thereunder, and as may be necessary to comply
         with any applicable state securities laws, and such failure has
         continued for a period of fifteen (15) days, or (3) if the Holder
         holds a Note, a written notice to the Company that the Holder is
         exercising the Warrant (or a portion thereof) by authorizing the
         Company to withhold and apply such amount of the accrued but unpaid
         interest under the Note as is equal to the Aggregate Purchase Price
         (and such amount of the accrued and unpaid interest under the Note
         shall no longer be payable to the Holder).

         (ii)    Certificates for shares of Common Stock purchased upon
exercise of this Warrant shall be delivered by the Company to the Purchaser
within three (3) business days after the date of the exercise, together with
cash in lieu of any fraction of a share of Common Stock that would be issuable
upon such exercise in an amount equal to the Market Price of such fractional
share as of the date of exercise.  No fractional shares of Common Stock or
scrip representing fractional shares Common Stock shall be issued upon an
exercise of this Warrant.  Unless this Warrant has expired or all of the
purchase rights represented hereby have been exercised, the Company shall
prepare a new Warrant, substantially identical hereto, representing the rights
formerly represented by this Warrant which have not expired or been exercised
and shall within such three (3) day period, deliver such new Warrant to the
Purchaser.

         (iii)   The shares of Common Stock issuable upon the exercise of this
Warrant shall be deemed to have been issued to the Purchaser at the time of
exercise, and the Purchaser shall be deemed for all purposes to have become the
record holder of such Common Stock at such time.

         (v)     The Company shall not close its books against the transfer of
this Warrant or of any share of Common Stock issued or issuable upon the
exercise of this Warrant in any manner which interferes with the timely
exercise of this Warrant.  The Company shall from time to time take all such
action as may be necessary to assure that the par value per share of the
unissued Common Stock acquirable upon exercise of this Warrant is at all times
equal to or less than the Purchase Price then in effect.

         (vi)    The Company shall assist and cooperate with any Registered
Holder or Purchaser to make any governmental filings or obtain any governmental
approvals required prior to or in connection with any exercise of this Warrant
(including, without limitation, making any filings required to be made by the
Company).

3.       EXPIRATION DATE

         The Warrant evidenced hereby may not be exercise before the
Commencement Date or after the Expiration Date with respect to the shares of
the Common Stock as to which the Warrant may be exercised and, to the extent
not exercised by the Expiration Date, the Warrant evidenced hereby shall become
void.

4.       ADJUSTMENTS

         Subject to the provisions of this Section 4, the Purchase Price and
the number of shares of the Common Stock as to which the Warrant may be
exercised shall be subject to adjustment from time to time as hereinafter set
forth:

         4.1     Adjustment of Number of Shares Upon Adjustment of Purchase
Price Under the Note.  In the event that before May 1, 1998, the Conversion
Price (as defined in the Purchase Agreement) is reduced pursuant to Section 6.1
of the Purchase Agreement, then this Warrant and any other Warrant collectively
shall cease to be exercisable with respect to that number of shares of Common
Stock equal to (i) the Initial Purchase Amount (as defined below), multiplied
by (ii) a fraction the numerator of which is equal to the amount obtained by
subtracting the Conversion Price immediately after the decrease in the
Conversion Price pursuant to Section 6.1 of the Purchase Agreement from the
Conversion Price immediately prior to such decrease and the denominator of
which is the Conversion Price immediately after such decrease, minus (iii) the
number of shares of Common Stock theretofore issued upon conversion of the
Notes (such number to be adjusted to reflect any changes in capitalization
described in Section 4.5), and divided by (iv) 2.2727; provided that the number
of shares of Common Stock for which this Warrant shall cease to be exercisable
pursuant to this Section 4.1 shall not exceed twenty percent (20%) of the
Initial Purchase Amount.  For purposes of this Section 4.1, the term "Initial
Purchase Amount" shall mean the number of shares of Common Stock for which this
Warrant was potentially exercisable on November 7, 1996, as adjusted pursuant
to Section 4.5 and 4.7 of this Warrant.

         4.2     Expression of Purchase Price and Number of Shares.
Irrespective of any adjustments or change in the Purchase Price or the number
of securities actually purchasable under the Warrant, the Warrants theretofore
and thereafter issued may continue to express the purchase price and the number
of securities purchasable thereunder as the Purchase Price and the number of
securities purchasable were expressed in the Warrant when initially issued.

         4.3     Effect on Purchase Price and Number of Shares of Certain
Events.  If and whenever on or after the Effective Date, the Company issues or
sells any share of Common Stock (other than upon exercise of an Option or
conversion of Convertible Securities outstanding immediately before the
Effective Date), or in accordance with this Section 4.3 is deemed to have
issued or sold any share of Common Stock, for a consideration per share less
than the Purchase Price in effect immediately prior to such time, then
immediately upon such issuance or sale the Purchase Price shall be reduced to
the price per share at which such share of Common Stock has been issued or sold
or is deemed pursuant to this Section 4 to have been issued or sold.  Upon each
such adjustment of the Purchase Price, the number of shares of Common Stock
issuable upon the exercise of each Warrant (to the extent not theretofore
exercised) shall be increased to a number determined by multiplying the number
of such shares so purchasable immediately prior to such adjustment by a
fraction, the numerator of which shall be the Purchase Price in effect
immediately prior to such adjustment and the denominator of which shall be the
Purchase Price in effect immediately after such adjustment.  For purposes of
determining the adjusted Purchase Price under this Section 4.3, the following
shall be applicable:





                                      E-16
<PAGE>   55
                 (i)      Issuance of Rights or Options.  If on or after the
Effective Date the Company in any manner issues, grants or sells any Options
and the price per share for which a share of Common Stock is issuable upon the
exercise of any such Option, or upon conversion or exchange of any Convertible
Security issuable upon exercise of such Option, is less than the Purchase Price
in effect immediately prior to the time of the granting or sale of such Option,
then such share of Common Stock shall be deemed to have been issued and sold by
the Company at such time for such price per share.  For purposes of this
Section 4.3(i), the "price per share for which a share of Common Stock is
issuable" shall be equal to the sum of the amount of consideration (if any)
received or receivable by the Company with respect to the issuance, grant or
sale of the Option, plus the amount of consideration (if any) that would be
received by the Company with respect to exercise of the Option in full plus the
amount of consideration (if any) that would be received by the Company with
respect to conversion or exchange in full of any Convertible Security issuable
upon exercise of such Option, all divided by the total number of shares of
Common Stock issuable upon exercise of the Option and conversion or exchange of
the Convertible Security.  No further adjustment of the Purchase Price shall be
made upon the actual issue of such Common Stock or of such Convertible Security
upon the exercise of such Options or upon the actual issue of such Common Stock
upon conversion or exchange of such Convertible Security.

                 (ii)     Issuance of Convertible Securities.  If on or after
the Effective Date the Company in any manner issues, grants or sells any
Convertible Security and the price per share for which a share of Common Stock
is issuable upon conversion or exchange thereof is less than the Purchase Price
in effect immediately prior to the time of such issue or sale, then such share
or shares of Common Stock shall be deemed to have been issued and sold by the
Company at such time for such price per share.  For the purposes of this
Section 4.3(ii), the "price per share for which a share of Common Stock is
issuable" shall be equal to the sum of the amount of consideration (if any)
received or receivable by the Company with respect to the issuance, grant or
sale of the Convertible Security plus the amount of consideration (if any) that
would be received by the Company with respect to the conversion or exchange of
such Convertible Security in full, all divided by the total number of shares of
Common Stock issuable upon conversion or exchange of the Convertible Security.
No further adjustment of the Purchase Price shall be made upon the actual issue
of such Common Stock upon conversion or exchange of any Convertible Security,
and if any such issue or sale of such Convertible Security is made upon
exercise of any Options for which adjustments of the Purchase Price has been or
is to be made pursuant to other provisions of this Section 4, no further
adjustment of the Purchase Price shall be made by reason of such issue or sale.

                 (iii)    Change in Option Price or Conversion Rate.  If the
amount to be received by the Company upon the exercise of any Options
outstanding as of the Effective Date, the additional consideration, if any,
payable upon the issuance, conversion or exchange of any Convertible Securities
outstanding as of the Effective Date, or the rate at which any Convertible
Securities outstanding as of the Effective Date are convertible into or
exchangeable for Common Stock changes at any time after the Effective Date,
then such Option or Convertible Security and the Common Stock deemed issuable
upon exercise, conversion or exchange thereof shall be deemed for purposes of
this Section 4.3 to have been issued as of the date of such changes;





                                      E-17
<PAGE>   56
provided that no such change shall at any time cause the Purchase Price
hereunder to be increased.

                 (iv)     Treatment of Expired Options and Unexercised
Convertible Securities.  Upon the expiration of any Option described in Section
4.3(i) or the termination of any right to convert or exchange any Convertible
Securities described in Section 4.3(ii) without the exercise or conversion in
whole or in part of such Option or Convertible Security, the Purchase Price
then in effect and the number of shares of Common Stock issuable hereunder
shall be adjusted immediately to the Purchase Price and the number of shares of
Common Stock which would have been in effect at the time of such expiration or
termination had such Option or Convertible Securities, never been issued,
granted or sold; provided that if such expiration or termination would result
in an increase in the Purchase Price then in effect, such increase shall not be
effective until the later of (A) the date of such expiration or termination and
(B) thirty (30) days after the Company has delivered notice of such expiration
or termination to the Noteholders.  For purposes of this Section 4.3, the
expiration or termination of any Option or Convertible Security which was
outstanding as of the Effective Date shall not cause the Purchase Price
hereunder to be adjusted unless, and only to the extent that, a change in the
term of such Option or Convertible Security caused it to be deemed to have been
issued after the Effective Date pursuant to Section 4.3(iii).

                 (v)      Calculation of Consideration Received.  If any Common
Stock, Options or Convertible Securities are issued or sold or deemed to have
been issued or sold for cash, the consideration received therefor shall be
deemed to be the net amount received by the Company therefor.  In case any
Common Stock, Options or Convertible Securities are issued or sold for a
consideration other than cash, the amount of the consideration other than cash
received by the Company shall be the fair value of such consideration, except
where such consideration consists of securities, in which case the amount of
consideration received by the Company shall be the Market Price thereof as of
the date of receipt.  In case any Common Stock, Options or Convertible
Securities are issued to the owners of the non-surviving entity in connection
with any merger in which the Company is the surviving corporation, the amount
of consideration therefor shall be deemed to be the fair value of such portion
of the net assets and business of the non-surviving entity as is attributable
to such Common Stock, Options or Convertible Securities, as the case may be.
The fair value of any consideration other than cash or securities shall be
determined jointly by the Company and the Registered Holders.  If such parties
are unable to reach agreement, such fair value shall be determined by appraisal
pursuant to Section 12.

                 (vi)     Integrated Transactions.  In case any Option is
issued in connection with the issue or sale of other securities of the Company,
together comprising one integrated transaction in which no specific
consideration is allocated to such Options by the parties thereto, the Options
shall be deemed to have been issued without consideration.

                 (vii)    Each Series a Separate Security.  In case an
agreement relating to Options or Convertible Securities provides that more than
one Purchase Price, conversion or exchange provisions are applicable to the
securities issuable thereunder, then the securities subject to each different
exercise price, conversion or exchange provisions shall be deemed to be subject
to separate Options or Convertible Securities for purposes of applying this
Section 4.3.

                 (viii)   Treasury Shares.  The Common Stock outstanding at any
given time does not include shares owned or held by or for the account of the
Company or any Subsidiary, and the disposition of any shares so owned or held
shall be considered an issue or sale of Common Stock.

                 (ix)     Record Date.  If the Company takes a record of the
holders of Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in Common Stock, Options or in
Convertible Securities or (B) to subscribe for or purchase Common Stock,
Options or Convertible Securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such
other distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

         4.4     Certain Sales of Common Stock.  If and whenever on or after
the Effective Date the Company issues or sells, or in accordance with Section
4.3 is deemed to have issued or sold, any share of Common Stock for a
consideration per share that is equal to or greater than the Purchase Price in
effect immediately prior to such issuance or sale, but that does not exceed the
lower of the Market Price per share of Common Stock on the day of such issuance
or sale and One Hundred and Fifteen percent (115%) of the Purchase Price in
effect immediately prior to such issuance or sale, then immediately upon such
issuance or sale the Purchase Price shall be reduced to the price determined by
multiplying the Purchase Price in effect immediately prior to such issuance or
sale by a fraction, the numerator of which shall be the sum of (i) the number
of shares of Common Stock outstanding immediately prior to such issuance or
sale multiplied by the Market Price per share of Common Stock on the day of
such issuance or sale, plus (ii) the number of shares issued or sold, or in
accordance with Section 4.3 deemed to have been issued or sold, multiplied by
the price per share at which such Common Stock was issued or sold, or in
accordance with Section 4.3 is deemed to be issued or sold, and the denominator
of which shall be the product of (A) the total number of shares of Common Stock
outstanding immediately after such issuance or sale, multiplied by (B) the
Market Price per share of Common Stock on the day of such issuance or sale.
Upon any calculation of the Purchase Price described in the first sentence of
this Section 4.4, the number of shares of Common Stock issuable upon the
exercise of each Warrant shall be increased to a number determined by
multiplying the number of such shares so purchasable immediately prior to such
adjustment by a fraction, the numerator of which shall be the Purchase Price in
effect immediately prior to such adjustment and the denominator of which shall
be the Purchase Price in effect immediately after such adjustment.

         4.5     Subdivision or Combination of Common Stock.  If the Company at
any time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the Purchase Price in effect immediately prior to
such subdivision shall be proportionately reduced, and the number of shares of
Common Stock obtainable upon exercise of this Warrant (to the extent not
theretofore exercised) and the Initial Purchase Amount shall be proportionally
increased.  If the Company at any time combines (by reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, the Purchase Price shall be proportionately
increased, and the number of shares of Common Stock issuable upon exercise of
this Warrant (to the extent not theretofore exercised) and the Initial Purchase
Amount shall be proportionally decreased.





                                      E-19
<PAGE>   58
         4.6     Reorganization, Reclassification, Consolidation, Merger or
Sale.  Any recapitalization, reorganization, reclassification, consolidation,
merger, sale of all or the majority of the Company's assets or other
transaction, in each case which is effected in such a way that the holders of
Common Stock are entitled to receive (either directly or upon subsequent
liquidation) stock, securities or assets with respect to or in exchange for
Common Stock is referred to herein as "Organic Change." Prior to the
consummation of any Organic Change, the Company shall make appropriate
provision (in form and substance satisfactory to the Registered Holders) to
insure that each of the Registered Holders shall thereafter have the right to
acquire and receive, in lieu of or in addition to (as the case may be) the
shares of Common Stock immediately theretofore acquirable and receivable upon
the exercise of such Warrant, such shares of stock, securities or assets as may
be issued or payable in connection with such Organic Change with respect to or
in exchange for the number of shares of Common Stock issuable had this Warrant
been fully exercised immediately prior to such Organic Change.  In any such
case, the Company shall make appropriate provision (in form and substance
satisfactory to the Registered Holders) with respect to such holders' rights
and interests to insure that the provisions of this Section 4 shall thereafter
be applicable to the Warrants (including, in the case of any such
consolidation, merger or sale in which the successor entity or purchasing
entity is other than the Company, an immediate reduction in the Purchase Price
to the value of the Common Stock reflected by the terms of such consolidation,
merger or sale, and a corresponding immediate adjustment in the number of
shares of Common Stock issuable upon exercise of this Warrant (to the extent
not theretofore exercised), if the value so reflected is less than the Purchase
Price in effect immediately prior to such consolidation, merger or sale).  The
Company shall not effect any such consolidation, merger or sale, unless prior
to the consummation thereof, the successor entity (if other than the Company)
resulting from consolidation or merger or the entity purchasing such assets
assumes by written instrument (in form and substance satisfactory to the
Registered Holders), the obligation to deliver to each such holder such shares
of stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

         4.7     Certain Events.  If any event occurs of the type contemplated
by the provisions of this Section 4 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation
rights, phantom stock rights or other rights with equity features or any
dividend or distribution of the capital stock issued by any Person other than
the Company), then the Company's Board of Directors shall make an appropriate
adjustment in the Purchase Price and the number of shares issuable upon
exercise of this Warrant (to the extent not theretofore exercised)  and the
Initial Purchase Amount so as to protect the rights of the Registered Holders;
provided that no such adjustment shall increase the Purchase Price as otherwise
determined pursuant to this Section 4.

         4.8     Calculation of Purchase Price; Notices.

                 (i)      All calculations of the Purchase Price under this
Section 4 shall be computed to the nearest One-Thousandth (1/1000th) of a cent.

                 (ii)     Immediately upon any adjustment of the Purchase
Price, the Company shall give written notice thereof to the Registered Holders,
setting forth in reasonable detail and certifying the calculation of such
adjustment, provided however, that such notice shall not be





                                      E-20
<PAGE>   59
deemed to be conclusive as to the Purchase Price calculation.  At the request
of a Registered Holder, the Company shall certify the Purchase Price of and the
number of shares for which a Warrant at the time may be exercised.

                 (iii)    The Company shall given written notice to the
Registered Holders at least thirty (30) days prior to the date on which the
Company closes its books or takes a record (A) with respect to any subdivision
or combination of the Common Stock that is subject to Section 4.5, or any other
dividend or distribution upon the Common Stock, (B) with respect to any pro
rata subscription offer to holders of Common Stock or (C) for determining
rights to vote with respect to any Organic Change, dissolution or liquidation.

                 (iv)     The Company shall also give written notice to the
Registered Holders at least thirty (30) days prior to the date on which any
Organic Change, dissolution or liquidation shall take place.

         4.9     Excluded Transactions.  The provisions of this Section 4 shall
not apply to the following transactions:  (i) the conversion of the Notes and
exercise of the Warrant, (ii) the issuance of Common Stock in the acquisition
of the minority ownership interests in U.S.  Drug Testing, Inc. and Good Ideas
Enterprises, Inc. as previously disclosed to the public, (iii) the acquisition
of any Person engaged exclusively in, or engaged in a business directly related
to, the business of substance abuse testing, (iv) conversion of shares of the
Series A Preferred Stock of the Company (the "Preferred Stock") outstanding as
of the Effective Date, in accordance with the terms of the Preferred Stock, (v)
transactions that are subject to Section 15.2 or Section 15.3 of the Purchase
Agreement, (vi) Options granted or to be granted to officers of the Company,
not previously employed by the Company, as an inducement essential to entering
into a contract of employment with the Company provided that the total number
of shares of Common Stock subject to all such excluded Options that may be
outstanding at any one time shall not exceed Two Hundred Fifty Thousand
(250,000) shares of Common Stock, and (vii) the issuance of 200,000 shares of
Common Stock to John Sloan described in Section 8.2(c).

5.       NO RIGHTS OR LIABILITIES AS STOCKHOLDERS AND NOTICE TO REGISTERED
HOLDER

         Nothing contained herein shall be construed as conferring upon the
Registered Holders the right to vote or to consent or to receive notice as a
stockholder in respect of the meetings of shareholders for the election of
directors of the Company or any other matter, or any other rights whatsoever as
a stockholder of the Company; provided, however, that in the event that:

         (a)     the Company shall take a record of the holders of its Common
Stock or other stock or securities for the purpose of entitling them to receive
any dividend or other distribution, or any right to subscribe for or purchase
any shares of stock of any class or any other securities or to receive any
other right;

         (b)     the Company shall take action to accomplish any capital
reorganization, or reclassification of the capital stock of the Company, or a
consolidation or merger of the Company into, or a sale of all or substantially
all of its assets to, another corporation;





                                      E-21
<PAGE>   60
         (c)     the Company shall take action to redeem or convert any or all
of outstanding Common Stock or other stock or securities of the Company; or

         (d)     the Company shall take action looking to a voluntary
dissolution, liquidation or winding up of the Company; 

then, and in each such case, the Company shall mail or cause to be mailed to
the Registered Holders of this Warrant a notice specifying, as the case may be,
(i) the date on which a record is to be taken for the purpose of such dividend,
distribution or right, or (ii) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation,
winding-up, redemption or conversion is to take place, and the time, if any, is
to be fixed, as of which the holders of record of Common Stock or such other
stock or securities shall be entitled to exchange their shares of Common Stock
or such other stock or securities for securities or other property deliverable
upon such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation, winding-up, conversion or redemption.  Such notice
shall be delivered at least thirty (30) days prior to the date therein
specified.

6.       DUTY TO REGISTER COMMON STOCK

         Promptly after the Effective Date, the Company shall file a
registration statement with the Securities and Exchange Commission ("SEC")
under the Securities Act registering the Company's offer and sale of the
Underlying Common Stock and the Company shall use its best efforts to have the
SEC declare effective such registration statement within three (3) months after
the Effective Date.  The Company shall similarly register the Company's offer
and sale of the Underlying Common Stock under any applicable state securities
laws.  So long as any Warrants remain outstanding, the Company shall file such
amendments and/or supplements to any registration statement under the
Securities Act or under any state securities laws covering the offer and sale
of such Underlying Common Stock and supplement and keep current any prospectus
forming a part of such registration statement as may be necessary to permit the
Company to deliver to a Registered Holder upon any sale of the Underlying
Common Stock a prospectus meeting the requirements of the Securities Act and
the regulations of the SEC thereunder, and as may be necessary to comply with
any applicable state securities laws.  The shares of Common Stock issuable
under this Warrant are subject to a Registration Rights Agreement with the
Company dated November 7, 1996.

7.       TRANSFERS AND EXCHANGES

         7.1     Warrant Transferable.  Subject to the transfer conditions
referred to in the legend endorsed hereon, this Warrant and all rights
hereunder (including those under the Purchase Agreement) are transferable, in
whole or in part, without charge to the Registered Holders, upon surrender of
this Warrant with a properly executed Assignment (in the form of Exhibit B
hereto) at the principal office of the Company.

         7.2     Warrant Exchangeable for Different Denominations.  This
Warrant is exchangeable, upon the surrender hereof by the Registered Holders at
the principal office of the Company, for new Warrants of like tenor
representing in the aggregate the purchase rights





                                      E-22
<PAGE>   61
hereunder, and each of such new Warrants shall represent such portion of such
rights as is designated by the Registered Holders at the time of such
surrender.  The date the Company initially issues this Warrant shall be deemed
to be the "Date of Issuance" hereof regardless of the number of times new
certificates representing the unexpired and unexercised rights formerly
represented by this Warrant shall be issued.  All Warrants representing
portions of the rights hereunder are referred to herein as the "Warrants."

8.       VALID ISSUANCE AND PAYMENT OF TAXES

         All shares of Common Stock issued upon the exercise of this Warrant
shall be validly issued, fully paid and non-assessable, and the Company shall
pay all taxes and other governmental charges that may be imposed in respect of
the issue or delivery thereof.  The Company shall not be required to pay any
tax or other charge imposed in connection with any transfer involved in the
issuance of any certificate for shares of Common Stock in any name other than
that of the Registered Holder of this Warrant, and in such case the Company
shall not be required to issue or deliver any stock certificate or security
until such tax or other charge has been paid, or it has been established to the
Company's reasonable satisfaction that no tax or other charge is due.

9.       MUTILATED OR MISSING WARRANTS

         In case any of the Warrants shall be mutilated, lost, stolen or
destroyed, the Company shall issue and deliver in exchange and substitution
for, and upon cancellation of, the mutilated Warrant, or in lieu of, and in
substitution for, the Warrant lost, stolen or destroyed, a new Warrant of like
tenor and representing an equivalent right or interest, but only upon receipt
of reasonable evidence of such loss, theft, or destruction of such Warrant.

10.      RESERVE

         The Company hereby covenants that at all times there shall be reserved
for issuance such number and type of securities as the Registered Holders are
entitled to receive upon exercise of the Warrants.  Prior to the issuance of
any equity securities (or any instrument exercisable for or convertible into
equity securities) and whenever otherwise required to satisfy this Section 10,
the Company will amend its Articles of Incorporation to the extent necessary to
ensure that there is reserved for issuance a sufficient quantity of such equity
securities (and Common Stock into which such equity securities may be
convertible) as the Registered Holders are entitled to receive upon exercise of
this Warrant.

11.      NO IMPAIRMENT

         The Company will not, by amendment of its Certificate of Incorporation
or bylaws, or through reorganization, consolidation, merger, dissolution, issue
or sale of securities, sale of assets or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Registered Holders against
impairment.  Without limiting the generality of the foregoing, the Company (a)
shall not increase the par value of any shares issuable upon exercise





                                      E-23
<PAGE>   62
of this Warrant above the Purchase Price and (b) will take all such action as
may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and non-assessable shares of Common Stock upon
exercise of this Warrant.

12.      APPRAISAL

                 In case of any dispute as to valuation of a security under
this Agreement, the fair value of such security shall be determined by an
appraiser without any discount for liquidity or restrictions under the
Securities Act.  This appraisal process shall be instituted within fourteen
(14) days after a party to this Agreement notifies the other party of its
desire to submit the issue to an appraiser.  In the event the parties do not
agree on an appraiser within seven (7) days after a party to this Agreement
notifies the other party of its desire to submit the issue to an appraiser, the
fair value of such security shall be determined, without any discount for
liquidity or restrictions under the Securities Act, by the majority
determination of a panel of three (3) appraisers who shall be selected in the
following manner:  the Company shall select one (1) appraiser and the
Registered Holders shall jointly select one (1) appraiser and the two (2)
appraisers selected by the Company and the Registered Holders shall jointly
select a third appraiser.  The appraiser selected jointly by the parties and,
if applicable, each member of the appraisal panel shall be an individual who
personally and whose Affiliates shall not have a previous business relationship
with either party.  The appraiser and, if applicable, the appraisal panel shall
endeavor to complete the appraisal as soon as practicable.  The determination
of such appraiser and , if applicable, the appraisal panel shall be final and
binding on the Company and the Registered Holders, and the fees and expenses of
such appraisal shall be borne equally by the Company, on the one hand, and the
Registered Holders, on the other.

13.      NOTICES

                 Except as may be otherwise provided herein, all notices and
other communications required or permitted hereunder shall be in writing and
shall be conclusively deemed to have been duly given (a) when hand delivered to
the other party; (b) when received when sent by facsimile to number set forth

effective unless either (i) a duplicate copy of such facsimile notice is

notice either by facsimile or any other method described in this Section 13;
