                                                                 EXHIBIT 2(c)(1)


                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER dated as of February 17, 1997 by and among
Substance Abuse Technologies, Inc., a Delaware corporation ("SAT"), U.S. Drug
Acquisition Corp., a Delaware corporation ("Acquisition Corp."), and U.S. Drug
Testing, Inc., a Delaware corporation ("U.S. Drug").



                                   WITNESSETH:

         WHEREAS, of the 5,221,900 shares of the common stock, $.001 par value
(the "U.S. Drug Common Stock"), of U.S. Drug outstanding as of the date hereof,
SAT is the owner of 3,500,000 shares and 1,721,900 shares (the "Minority U.S.
Drug Common Stock") are owned by persons other than SAT (the "U.S. Drug Minority
Stockholders");

         WHEREAS, the Board of Directors of each of SAT and Acquisition Corp.
have each adopted, approved and authorized the execution and delivery of this
Agreement and Plan of Merger (the "Agreement") so as to implement the subject
merger in compliance with the provisions of Section 251 of the General
Corporation Law of the State of Delaware (the "GCL") and Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code");

         WHEREAS, because of the relationships of all three of the directors of
U.S. Drug to SAT as current directors and/or officers thereof and as
securityholders thereof, the Board of Directors of U.S. Drug has only authorized
execution and delivery of the Agreement on the condition that approval of the
subject merger by U.S. Drug shall only be effected as a result of the obtaining
of consents thereto from the holders of more than 50% of the Minority U.S. Drug
Common Stock;

         WHEREAS, the Board of Directors of U.S. Drug intends to, and shall,
submit this Agreement and the subject merger to the stockholders of U.S. Drug
for approval to the extent required by the applicable provisions of the GCL; and

         WHEREAS, in connection with the subject merger and the solicitation of
stockholder consents thereto, SAT has filed a Registration Statement on Form
S-4, File No. 333-4790 (the "Registration Statement"), with the Securities and
Exchange Commission (the "SEC") pursuant to the Securities Act of 1933, as
amended (the "Securities Act"), the Registration Statement to include as Part I
thereof the prospectus and consent solicitation statement to be transmitted to
the U.S. Drug Minority Stockholders (such prospectus and consent solicitation
statement, as from time to time amended and/or supplemented, hereinafter
referred to as the "Consent Solicitation Statement/Prospectus") (a) with respect
to the solicitation of consents from the U.S. Drug Minority Stockholders to the
subject merger pursuant to Section 228 of the GCL and Section 14(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and (b) with

                                      E-2
   2
respect to the distribution of the shares of the SAT common stock, $.01 par
value (the "SAT Common Stock"), to the U.S. Drug Minority Stockholders in
exchange for their shares of the U.S. Drug Common Stock pursuant to the terms of
the Agreement, the subject merger, the Securities Act and the rules and
regulations promulgated thereunder;

         NOW THEREFORE, in consideration of the premises and the mutual
representations, warranties, covenants and agreements herein contained, the
parties hereto do hereby agree as follows:

         1. THE MERGER. Subject to the terms and conditions hereinbelow set
forth, on the Effective Date (as hereinafter defined in Section 11 hereof) U.S.
Drug shall be merged with and into Acquisition Corp. (the "Merger") and, in
connection therewith:

                  (a) except to the extent provided or permitted by applicable
law, the separate existence of U.S. Drug shall cease and terminate;

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

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

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

         2. INSTRUMENTS OF CONVEYANCE. Without limiting the generality of the
provisions of Section 1 hereof and/or the succession provisions of applicable
law, the officers and directors of U.S. Drug last in office shall (to the extent
they, or any of them, possess and/or may exercise the power to do so) execute,
deliver and/or record such deeds and/or other instruments of transfer and/or
conveyance, and take or cause to be taken, such other and further actions, as
the case may 

                                      E-3
   3
be, as shall be reasonably requested by Acquisition Corp. or SAT, or their legal
counsel, to vest, perfect, confirm, implement the transfer of, or establish in
the name, on behalf or for the account or the benefit of Acquisition Corp.,
title and/or possession of any or all of the assets, property, property
interests, rights, privileges, immunities, powers and franchises owned and/or
exercisable by U.S. Drug (or in which U.S. Drug had an interest and/or the power
to exercise immediately prior to the Effective Date) and which was vested, or
intended to be vested, in Acquisition Corp. pursuant to the provisions of this
Agreement and the Merger.

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

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

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

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

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

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

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




                                      E-4
   4
                  (a) Each issued and outstanding share of the U.S. Drug Common
Stock shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted and exchanged into 1.62 shares of the SAT Common
Stock, provided however, that to the extent any holder of the U.S. Drug Common
Stock shall be entitled, as a result of the foregoing conversion and exchange,
to receive less than a whole share of the SAT Common Stock, then and in any such
event:

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

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

The number of shares of the SAT Common Stock to be exchanged for each share of
U.S. Drug Common Stock was determined by dividing $2.625 (which is the value of
the shares of the SAT Common Stock to be exchanged for a share of the U.S. Drug
Common Stock) by an assumed market price of $1.625 (which was the closing sale
price reported by the American Stock Exchange on February 14, 1997, the last
trading date before the date of this Agreement).

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

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

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

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

                           (iii) Upon the issuance of shares of the SAT Common
Stock to the U.S. Drug Minority Stockholders in exchange for their shares of the
U.S. Drug Common Stock, there shall be credited to the capital account of SAT an
amount equal to $1.625 and, of the amount so credited, the portion thereof in
excess of the aggregate par value thereof shall be credited to the capital
surplus account.


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

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

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

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

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

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

                           (i) each Old Certificate shall, and be deemed to,
represent and evidence (for all corporate purposes other than the payment of
dividends and other distributions) that number of shares of the SAT Common Stock
into which the shares of the U.S. Drug Common Stock therein referred to are
convertible and exchangeable as herein provided and

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

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


                                      E-6
   6
                           (i) Until such time as the Old Certificate is
surrendered for replacement by a New Certificate(s) as herein provided, no
Distribution shall be paid over by SAT and/or the Exchange Agent to such holder
on, or with respect to, the shares of the SAT Common Stock evidenced by such Old
Certificate;

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

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

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

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

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

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




                                      E-7

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

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

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

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

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

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




                                      E-8
   8
                  (b) If a cash payment is received from the Partner after
execution, but on or prior to the first anniversary of the Effective Date, and
if such payment is not based on sales effected by the Partner or some similar
criteria, SAT or Acquisition Corp. will treat any such payment or payments as a
Special Payment as if received on the execution of the Marketing Agreement.

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

                  (d) On computing the Special Payment, there shall be deducted
from the payment received from the Partner the amount of any finder's fee paid
to secure the Partner or other costs related to obtaining such payment.

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

                  (f) Because SAT intends to merge Acquisition Corp. with and
into SAT if the Merger is consummated and thereafter conduct the former
operations of U.S. Drug as a division of SAT, all references to Acquisition
Corp. in this Section 4 shall be deemed to refer to SAT after such merger.

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

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

                                      E-9
   9
from the Pacific Stock Exchange. The Certificate of Merger shall provide for the
change of name of Acquisition Corp. to "U.S. Drug Testing, Inc."

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

                  (a) The parties hereto shall cooperate in the preparation
thereof consistent with the applicable requirements of the GCL, the Securities
Act and the Exchange Act and the rules and regulations promulgated under the
Securities Act and the Exchange Act by the SEC; and, without limiting the
generality of the foregoing, each of SAT and U.S. Drug shall promptly supply to
the other any and all information and material (relating to itself and/or the
subject transaction) as may be requested or required in connection with the
preparation and filing of the Registration Statement, including, without
limitation, all information concerning their respective officers, directors and
principal stockholders that is reasonably requested for inclusion in the Consent
Solicitation Statement/Prospectus; and each shall take and perform such other
and further acts and actions as shall be necessary or appropriate to cause the
prompt preparation, completion, filing, review, finalization and clearance of
the Registration Statement.

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

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

                                      E-10
   10
information and material as shall be needed to correct any such inaccuracy or
omission. SAT shall promptly advise U.S. Drug if at any time any of the
information or material contained in the Registration Statement and supplied by
SAT is or becomes incorrect, inaccurate or incomplete in any material respect.
SAT shall cause the preparation, review, clearance, approval and distribution of
such amended or supplemented material as shall be necessary to correct or
eliminate any such inaccuracies and/or omissions as provided in this Section
12(c).

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

                  (e) SAT does hereby agree to indemnify and hold harmless U.S.
Drug and each of its directors and officers, and each person, if any, other than
SAT who controls U.S. Drug within the meaning of Section 15 of the Securities
Act, from and against any and all losses, claims, damages, expenses or
liabilities, joint or several (including, without limitation, reasonable
attorneys' fees as herein provided), to which they or any of them may become
subject under the Securities Act, any other statute, common law or otherwise
and, except as provided below, shall reimburse U.S. Drug and each such director,
officer or controlling person for any legal or other expenses reasonably
incurred by them or any of them in connection with investigating or defending
any actions and/or claims, whether or not resulting in any liability, insofar as
such losses, claims, damages, expenses, liabilities or actions result from a
breach or alleged breach of the representations and warranties contained in
Sections 14 or 15 hereof or are based upon any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
the Consent Solicitation Statement/Prospectus or arise out of, or are based
upon, the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
but only insofar as any such untrue statement or omission or alleged untrue
statement or omission is with respect to the description of SAT or as to the
terms of its offer. Promptly after receipt by a party to be indemnified pursuant
to this Section 12(e) (the "Indemnitee") of notice of the commencement of any
action in respect of which indemnity may be sought against SAT hereunder, the
Indemnitee will promptly notify SAT in writing of the commencement thereof and
SAT shall, subject to the 

                                      E-11
   11
provisions stated below, assume the defense of the action (including the
employment of counsel, who shall be counsel reasonable satisfactory to U.S.
Drug), and shall make payment of expenses (including attorneys' fees as herein
provided) insofar as such action shall relate to any alleged liability in
respect of which indemnity may be sought against SAT. The Indemnitee or
Indemnitees shall have the right to employ separate counsel in any such action
and to participate in the defense thereof, but the fees and expenses of such
separate counsel shall not be at the expense of SAT unless the employment of
such separate counsel has been specifically authorized by SAT or there is a
conflict of interest which under the canon of ethics requires the employment of
separate counsel. SAT shall not be liable to any Indemnitee for any settlement
of any action effected without SAT's consent. Notwithstanding any provision of
this Agreement to the contrary, the obligations of SAT hereunder shall survive
the consummation of the transactions contemplated by this Agreement.

         13. U.S. DRUG REPRESENTATIONS AND WARRANTIES. In order to induce SAT
and Acquisition to execute and perform this Agreement, U.S. Drug does hereby

agreement or instrument to which U.S. Drug is a party or by which it is, or any
of its respective properties or assets are, or may be, bound or affected.

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

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

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

                  (c) (i) SAT has the full power and authority, corporate and
otherwise, to execute, deliver and perform this Agreement and to consummate the
transactions contemplated hereby; (ii) the execution, delivery and performance
of this Agreement, the consummation by SAT of the transactions herein
contemplated and the compliance by SAT with the terms of this Agreement have
been duly authorized by SAT; (iii) this Agreement is the valid and binding
obligation of SAT, enforceable in accordance with its terms, subject, as to
enforcement of remedies, to applicable bankruptcy, insolvency, reorganization,
moratorium and other laws affecting the rights of creditors generally and the
discretion of courts in granting equitable remedies; (iv) the execution,
delivery and performance of this Agreement by SAT and the consummation by SAT of
the transactions herein contemplated do not, and will not, with or without the
giving of notice or the lapse of time, or both, (A) result in any violation of
the Certificate of Incorporation (except possibly as indicated in Section 17(g)
hereof) or By-Laws of SAT, (B) result in a breach of, or a conflict with, any of
the terms or provisions of, or constitute a default under, or result in the
modification or termination of, or result in the creation or imposition of any
lien, security interest, charge or encumbrance upon any of the properties or
assets of SAT pursuant to, any indenture, mortgage, note, contract, commitment
or other 

                                      E-13
   13
agreement or instrument to which SAT is a party or by which it is, or any of its
respective properties or assets are, or may be, bound or affected; (C) to the
best knowledge of SAT, after due investigation, violate any existing applicable
law, rule, regulation, judgment, order or decree of any governmental agency or
court, domestic or foreign, having jurisdiction over SAT and/or any of the
Subsidiaries (other than U.S. Drug as to which SAT makes no representation), or
any of their respective properties or businesses; or (D) have any effect on any
license, permit, certification, registration, approval, consent or other
authorization necessary for SAT and/or any of the Subsidiaries (other than U.S.
Drug as to which SAT makes no representation) to own or lease and operate any of
its respective properties and to conduct its businesses or the ability of SAT
and/or any of the Subsidiaries (other than U.S. Drug as to which SAT makes no
representation) to make use thereof. No consent, approval, authorization or
order of any court, governmental agency, authority or body (other than as
required pursuant to the Securities Act, the Exchange Act and/or state
securities or "take over" statutes and the rules and regulations promulgated
under any of the foregoing and/or any party to an agreement to which SAT is a
party and/or by which it is bound) is required in connection with the execution,
delivery and performance of this Agreement and/or the consummation by SAT of the
transactions contemplated by this Agreement.

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

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

                                      E-14
   14
accounting principles, applied on a consistent basis throughout the entire
periods involved. The SAT Unaudited Financial Statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and the instructions to Form 10-Q and Item 310 of Regulation S-K of
the SEC. Accordingly, the interim financial statements may not include all of
the information and footnotes required by generally accepted accounting
principles. In the opinion of SAT's management, all adjustments (consisting of
normal recurring adjustments) considered necessary for a fair presentation have
been included. As of the date of any balance sheet forming a part of the SAT
Financial Statements and, except as and to the extent reflected or reserved
against therein, neither SAT nor any of the Subsidiaries (other than U.S. Drug
as to which SAT makes no representation) had any material liabilities, debts,
obligations or claims (absolute or contingent) asserted against it or them
and/or which should have been reflected in a balance sheet or the notes thereto;
and all assets reflected thereon are properly reported and present fairly the
value of the assets therein stated in accordance with generally accepted
accounting principles.

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

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

                  (h) Except as is set forth on Exhibit "D" hereto, SAT and the
Subsidiaries (other than U.S. Drug as to which SAT makes no representation) own
all trademarks, service marks, tradenames, copyrights, similar rights and their
registrations, trade secrets, methods, practices, systems, ideas, know how and
confidential materials used or proposed to be used in the conduct of their
respective businesses as conducted as of the date hereof (collectively the
"Intangibles") free and clear of all liens, security interests, claims and
encumbrances and rights and options of third parties (including, without
limitation, former or current officers, directors, stockholders, employees and
agents); neither SAT nor any such Subsidiary has licensed or leased any of the
Intangibles and/or any interest therein to any person and/or entity except a
Subsidiary; neither SAT nor any such Subsidiary has infringed, nor is
infringing, upon the rights of others with respect to the Intangibles; neither
SAT nor any such Subsidiary has received any notice of conflict with the
asserted rights of others with respect to the Intangibles which could, singly or
in the aggregate, materially adversely affect its business as currently
conducted or prospects, financial condition or results of operations and SAT
knows of no basis therefor; and, to the best of the knowledge of SAT, no others
have infringed upon the Intangibles.

                                      E-15
   15
                  (i) Except as and to the extent reflected or reserved against
in the SAT Financial Statements and/or as set forth on Exhibit "E" annexed
hereto and made a part hereof, neither SAT nor any of the Subsidiaries (other
than U.S. Drug as to which SAT makes no representation) had, as at the
respective date of such SAT Financial Statements, any material liabilities,
debts, obligations or claims asserted against it, whether accrued, absolute,
contingent or otherwise, and whether due or to become due, including, but not
limited to, liabilities on account of due and unpaid taxes, other governmental
charges or lawsuits.

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

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

                  (l) Except as reported in the SAT Financial Statements and/or
as set forth on Exhibit "H" hereto and made a part hereof, there are no claims,
actions, suits, proceedings, arbitrations, investigations or inquiries before
any court or governmental agency, court or tribunal, domestic, or foreign, or
before any private arbitration tribunal, pending or, to the best of the
knowledge of SAT, threatened against SAT and/or any Subsidiary (other than U.S.
Drug as to which SAT makes no representation) or involving their respective
properties or businesses which, if determined adversely to SAT or such
Subsidiary, would, individually or in the aggregate, result in a material
adverse change in the financial position, stockholders' equity, results of
operations, properties, business, management or affairs of SAT or such
Subsidiary, or which question the validity of this Agreement or of any action
taken, or to be taken, by SAT pursuant to, or in connection with, this
Agreement; nor, to the best of the knowledge of SAT, is

                                      E-16
   16
there any basis for any such claim, action, suit, proceeding, arbitration,
investigation or inquiry to be made by any person and/or entity, including,
without limitation, any customer, supplier, lender, stockholder, former or
current employee, agent or landlord. There are no outstanding orders, judgments
or decrees of any court, governmental agency or other tribunal specifically
naming SAT and/or any Subsidiary (other than U.S. Drug as to which SAT makes no
representation) and/or enjoining SAT and/or any such Subsidiary from taking, or
requiring SAT and/or any such Subsidiary to take, any action and/or by which SAT
and/or any such Subsidiary is, and/or their respective properties or businesses
are, bound or subject.

                  (m) SAT and each of the Subsidiaries (other than U.S. Drug as
to which SAT makes no representation) has filed all federal, state, municipal
and local tax returns (whether relating to income, sales, franchise,
withholding, real or personal property or otherwise) required to be filed under
the laws of the United States and all applicable states and has paid in full all
taxes which are due pursuant to such returns or claimed to be due by any taxing
authority or otherwise due and owing. No penalties or other charges are, or will
become, due with respect to the late filing of any such return. To the best of
the knowledge of SAT, after due investigation, each such tax return heretofore
filed by SAT and each of such Subsidiaries correctly and accurately reflects the
amount of its tax liability thereunder. SAT has withheld, collected and paid all
other levies, assessments, license fees and taxes to the extent required and,
with respect to payments, to the extent that the same have become due and
payable.

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

                                      E-17
   17
dividends or other distributions of the assets of SAT have or will be declared
and/or paid prior to the Closing Date on or with respect to the SAT Common
Stock.

                  (o) Except as is set forth on Exhibit "J" hereto, since the
date of the most recent balance sheet included in the SAT Financial Statements,
there has not been, with respect to SAT and/or the Subsidiaries (other than U.S.
Drug as to which SAT makes no representation), except as set forth in or
permitted by this Agreement, or, in the ordinary course of business:

                           (i) Any change in their respective material business,
operations or financial condition, or the manner of managing or conducting their
respective business and operations; none of which changes, if any, has had a
material adverse effect on such business, operations or financial condition,
taken as a whole;

                           (ii) Any change in their respective accounting
methods or practices (including, without limitation, any change in depreciation,
amortization and/or good will policies or rates);

                           (iii) Any damage, destruction or loss (whether or not
covered by insurance) materially and adversely affecting their respective
assets, business, operations or financial condition;

                           (iv) Any declaration, setting, or payment of a
dividend or other distribution with respect to the SAT Common Stock or any
direct or indirect redemption, purchase or other acquisition by SAT of any of
the shares of the SAT Common Stock;

                           (v) Any issuance or sale of any shares of their
respective capital stock of any class or any other securities except for the
exercise of warrants to purchase shares of the SAT Common Stock outstanding
prior to the date hereof;

                           (vi) Any loan by any of them to any person or entity
and/or the issuance of any guaranty by any of them for or with respect to their
own or another's obligations;

                           (vii) Any waiver or release of any material right or
claim;

                           (viii) Any sale, lease, abandonment, assignment,
transfer, license or other disposition (including any agreement and/or option
for, or with respect to, any of the foregoing) by any of them of any material
real property or tangible or intangible assets, property or rights (and/or
interest therein);

                           (ix) Any incurrence of any material obligation or
liability, absolute or contingent;

                           (x) Any payment of any material obligation or
liability, absolute or contingent, except for current liabilities reflected in,
or shown on, the SAT Financial Statements 


                                      E-18
   18
and/or incurred subsequent to the date thereof in the ordinary course of
business and/or in connection with the transactions contemplated by this
Agreement;

                           (xi) Any labor problems and/or other events or
conditions of any character materially and/or adversely affecting, or which
might materially and/or adversely affect, the financial condition, business,
assets or prospects of any of them;

                           (xii) Any amendment, termination or modification of
any material agreement or license to which any of them is a party which has or
may have a material affect on the financial condition, business, assets or
prospects of any of them; and

                           (xiii) Any agreement by any of them to do or perform
any of the things described in this Section 14(o).

                  (p) At the Closing, all of the shares of the SAT Common Stock
to be issued by SAT pursuant to this Agreement shall be, and be deemed to be,
duly and validly authorized and, when issued to the U.S. Drug Minority
Stockholders in exchange for their shares of the U.S. Drug Common Stock, duly
and validly issued, fully paid and nonassessable and free and clear of all
federal and state issuance, stock and/or company taxes, liens, security
interests, claims, encumbrances and charges.

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

                  (a) Acquisition Corp. is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware, with full
power and authority, corporate and otherwise, and with all licenses, permits,
