         Agreement,  dated as of September 18, 1998,  between MEDTOX Scientific,
Inc., a Delaware  corporation  (the  "Company"),  and American  Stock Transfer &
Trust Company, a New York corporation (the "Rights Agent").
         The Board of  Directors  of the Company has  authorized  and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter  defined) of the Company  outstanding on September 30, 1998 (the
"Record Date"),  each Right representing the right to purchase one one-hundredth
of a Preferred Share (as hereinafter defined), upon the terms and subject to the
conditions  herein  set forth,  and has  further  authorized  and  directed  the
issuance  of one Right with  respect  to each  Common  Share  that shall  become
outstanding  between the Record Date and the earliest of the Distribution  Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined).
         Accordingly, in consideration of the premises and the mutual agreements
herein set forth, the parties hereby agree as follows:
         Section 1.  Certain  Definitions.  
For purposes of this Agreement, the following terms have the meanings indicated:
         (a)  "Acquiring  Person"  shall  mean  any  Person  (as  such  term  is
hereinafter  defined) who or which,  together with all Affiliates and Associates
(as such terms are hereinafter  defined) of such person, shall be the Beneficial
Owner (as such term is hereinafter  defined) of 20% or more of the Common Shares
of the  Company  then  outstanding,  but  shall not  include  the  Company,  any
Subsidiary  (as such term is hereinafter  defined) of the Company,  any employee
benefit  plan of the Company or any  Subsidiary  of the  Company,  or any entity
holding  Common  Shares  for  or  pursuant  to  the  terms  of  any  such  plan.
Notwithstanding  the foregoing,  no Person shall become an "Acquiring Person" as
the result of an acquisition of Common Shares by the Company which,  by reducing
the number of shares outstanding,  increases the proportionate  number of shares
beneficially  owned by such  Person to 20% or more of the  Common  Shares of the
Company then outstanding;  provided,  however, that if a Person shall become the
Beneficial  Owner  of 20% or more  of the  Common  Shares  of the  Company  then
outstanding  by reason of share  purchases by the Company and shall,  after such
share  purchases by the Company,  become the Beneficial  Owner of any additional
Common  Shares  of the  Company,  then  such  Person  shall be  deemed  to be an
"Acquiring Person".  Notwithstanding the foregoing, if the Board of Directors of
the Company  determines  in good faith that a Person who would  otherwise  be an

<PAGE>

"Acquiring  Person",  as defined  pursuant to the  foregoing  provisions of this
paragraph  (a),  has  become  such  inadvertently,  and such  Person  divests as
promptly as practicable a sufficient number of Common Shares so that such Person
would no longer be an "Acquiring  Person," as defined  pursuant to the foregoing
provisions of this  paragraph (a), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement.
         (b)  "Affiliate"  and  "Associate"  shall have the respective  meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations  under
the  Securities  Exchange Act of 1934, as amended (the  "Exchange  Act"),  as in
effect on the date of this Agreement.
     (c) A Person shall be deemed the "Beneficial  Owner" of and shall be deemed
to "beneficially own" any securities:
     (i) which such  Person or any of such  Person's  Affiliates  or  Associates
beneficially owns, directly or indirectly;
                  (ii) which such Person or any of such  Person's  Affiliates or
         Associates  has (A)  the  right  to  acquire  (whether  such  right  is
         exercisable  immediately or only after the passage of time) pursuant to
         any  agreement,  arrangement  or  understanding  (other than  customary
         agreements with and between underwriters and selling group members with
         respect to a bona fide  public  offering  of  securities),  or upon the
         exercise of  conversion  rights,  exchange  rights,  rights (other than
         these Rights),  warrants or options, or otherwise;  provided,  however,
         that a Person  shall  not be  deemed  the  Beneficial  Owner  of, or to
         beneficially own,  securities tendered pursuant to a tender or exchange
         offer  made by or on  behalf  of such  Person  or any of such  Person's
         Affiliates,  or Associates until such tendered  securities are accepted
         for  purchase  or  exchange;  or (B) the right to vote  pursuant to any
         agreement,  arrangement or  understanding;  provided,  however,  that a
         Person shall not be deemed the Beneficial  Owner of, or to beneficially
         own, any security if the  agreement,  arrangement or  understanding  to
         vote such security (1) arises solely from a revocable  proxy or consent
         given  to  such  Person  in  response  to a  public  proxy  or  consent
         solicitation  made pursuant to, and in accordance  with, the applicable
         rules and regulations promulgated under the Exchange Act and (2) is not

<PAGE>

         also then  reportable  on Schedule  13D under the  Exchange Act (or any
         comparable or successor report); or
                  (iii) which are beneficially owned, directly or indirectly, by
         any  other  Person  with  which  such  Person  or any of such  Person's
         Affiliates   or   Associates   has  any   agreement,   arrangement   or
         understanding   (other  than  customary  agreements  with  and  between
         underwriters  and selling  group  members  with  respect to a bona fide
         public offering of securities)  for the purpose of acquiring,  holding,
         voting  (except to the extent  contemplated  by the  proviso to Section
         1(c)  (ii)  (B))  or  disposing  of  any  securities  of  the  Company.
         Notwithstanding  anything in this definition of Beneficial Ownership to
         the contrary, the phrase "then
outstanding,"  when used with  reference to a Person's  Beneficial  Ownership of
securities of the Company,  shall mean the number of such securities then issued
and  outstanding  together with the number of such  securities not then actually
issued and  outstanding  which such Person  would be deemed to own  beneficially
hereunder.
         (d) "Business Day" shall mean any day other than a Saturday,  a Sunday,
or a day on which banking  institutions  in New York are authorized or obligated
by law or executive order to close.
         (e) "Close of  business"  on any given  date shall mean 5:00 P.M.,  New
York City time,  on such  date;  provided,  however,  that if such date is not a
Business Day it shall mean 5:00 P.M., New York City time, on the next succeeding
Business Day.
         (f) "Common  Shares" when used with reference to the Company shall mean
the shares of common stock,  par value $0.15 per share, of the Company.  "Common
Shares" when used with reference to any Person other than the Company shall mean
the capital stock (or equity  interest)  with the greatest  voting power of such
other  Person or, if such other Person is a Subsidiary  of another  Person,  the
Person or Persons which ultimately control such first-mentioned Person.
     (g)  "Distribution  Date"  shall  have the  meaning  set forth in Section 3
hereof.
     (h) "Final  Expiration  Date" shall have the meaning set forth in Section 7
hereof.
     (i) "Person" shall mean any individual,  firm, corporation or other entity,
and shall include any successor (by merger or otherwise) of such entity.

<PAGE>

         (j)   "Preferred   Shares"   shall  mean  shares  of  Series  A  Junior
Participating  Preferred Stock, par value $1.00 per share, of the Company having
the rights and  preferences set forth in the Form of Certificate of Designations
attached to this Agreement as Exhibit A.
     (k) "Redemption Date" shall have the meaning set forth in Section 7 hereof.
         (l)  "Shares  Acquisition  Date"  shall  mean the first  date of public
announcement by the Company or an Acquiring  Person that an Acquiring Person has
become such.
         (m)  "Subsidiary"  of any Person  shall mean any  corporation  or other
entity of which a majority of the voting power of the voting  equity  securities
or equity interest is owned, directly or indirectly, by such Person.
         Section  2. Appointment  of Rights Agent.
The Company hereby appoints the Rights Agent to act as agent for the Company and
the holders of the Rights (who, in accordance with Section 3 hereof, shall prior
to the Distribution Date also be the holders of the Common Shares) in accordance
with the terms and conditions  hereof,  and the Rights Agent hereby accepts such
appointment.  The Company may from time to time appoint such co-Rights Agents as
it may deem necessary or desirable.
         Section   3.   Issue   of  Right Certificates.  
(a) Until the earlier of (i) the tenth day after the Shares  Acquisition Date or
(ii) the tenth  business day (or such later date as may be  determined by action
of the Board of Directors  prior to such time as any Person becomes an Acquiring
Person)  after  the  date of the  commencement  by any  Person  (other  than the
Company, any Subsidiary of the Company, any employee benefit plan of the Company
or of any  Subsidiary of the Company or any entity  holding Common Shares for or
pursuant to the terms of any such plan) of, or of the first public  announcement
of the  intention of any Person (other than the Company,  any  Subsidiary of the
Company,  any employee  benefit plan of the Company or of any  Subsidiary of the
Company or any entity  holding Common Shares for or pursuant to the terms of any
such plan) to commence,  a tender or exchange  offer the  consummation  of which
would  result in any  Person  becoming  the  Beneficial  Owner of Common  Shares
aggregating  20% or more of the then  outstanding  Common Shares  (including any
such date which is after the date of this Agreement and prior to the issuance of
the  Rights;  the  earlier  of  such  dates  being  herein  referred  to as  the
"Distribution  Date"),  (x)  the  Rights  will  be  evidenced  (subject  to  the
provisions  of Section  3(b)  hereof)  by the  certificates  for  Common  Shares
registered in the names of the holders thereof (which certificates shall also be

<PAGE>

deemed to be Right Certificates) and not by separate Right Certificates, and (y)
the right to receive Right  Certificates will be transferable only in connection
with  the  transfer  of  Common  Shares.   As  soon  as  practicable  after  the
Distribution  Date, the Company will prepare and execute,  the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid mail, to each
record holder of Common  Shares as of the close of business on the  Distribution
Date, at the address of such holder shown on the records of the Company, a Right
Certificate,   in  substantially   the  form  of  Exhibit  B  hereto  (a  "Right
Certificate"),  evidencing  one Right for each Common  Share so held.  As of the
Distribution   Date,  the  Rights  will  be  evidenced   solely  by  such  Right
Certificates.
         (b) On the  Record  Date,  or as soon as  practicable  thereafter,  the
Company will send a copy of a Summary of Rights to Purchase Preferred Shares, in
substantially  the form of  Exhibit  C  hereto  (the  "Summary  of  Rights),  by
first-class,  postage-prepaid mail, to each record holder of Common Shares as of
the close of business on the Record Date, at the address of such holder shown on
the records of the  Company.  With  respect to  certificates  for Common  Shares
outstanding as of the Record Date, until the Distribution  Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together  with a copy of the  Summary  of  Rights  attached  thereto.  Until the
Distribution Date (or the earlier of the Redemption Date or the Final Expiration
Date),  the  surrender  for  transfer  of  any  certificate  for  Common  Shares
outstanding on the Record Date,  with or without a copy of the Summary of Rights
attached  thereto,  shall also constitute the transfer of the Rights  associated
with the Common Shares represented thereby.
         (c) Certificates for Common Shares which become outstanding (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this  paragraph  (c)) after the  Record  Date but prior to the  earliest  of the
Distribution  Date, the Redemption Date or the Final  Expiration Date shall have
impressed on, printed on, written on or otherwise  affixed to them the following
legend:
         This  certificate  also  evidences  and entitles  the holder  hereof to
         certain  rights  as set  forth in a  Rights  Agreement  between  MEDTOX
         Scientific,  Inc. and American  Stock Transfer & Trust Company dated as
         of September 18, 1998 (the "Rights Agreement"),  the terms of which are
         hereby  incorporated herein by reference and a copy of which is on file
         at the principal  executive  offices of MEDTOX  Scientific,  Inc. Under

<PAGE>

         certain  circumstances,  as set  forth in the  Rights  Agreement,  such
         Rights will be evidenced by separate certificates and will no longer be
         evidenced by this certificate. MEDTOX Scientific, Inc. will mail to the
         holder  of this  certificate  a copy of the  Rights  Agreement  without
         charge  after  receipt of a written  request  therefor.  Under  certain
         circumstances,  as set forth in the Rights Agreement,  Rights issued to
         any Person who  becomes an  Acquiring  Person (as defined in the Rights
         Agreement) may become null and void.

With respect to such  certificates  containing the foregoing  legend,  until the
Distribution  Date, the Rights associated with the Common Shares  represented by
such  certificates  shall  be  evidenced  by such  certificates  alone,  and the
surrender  for  transfer  of any such  certificate  shall  also  constitute  the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Company  purchases  or acquires  any Common  Shares after the
Record Date but prior to the Distribution  Date, any Rights associated with such
Common  Shares shall be deemed  cancelled  and retired so that the Company shall
not be entitled to exercise any Rights  associated  with the Common Shares which
are no longer outstanding.
         Section 4. Form of Right Certificates.
The Right  Certificates (and the forms of election to purchase  Preferred Shares
and of assignment to be printed on the reverse  thereof) shall be  substantially
the same as  Exhibit  B hereto  and may have  such  marks of  identification  or
designation and such legends,  summaries or endorsements  printed thereon as the
Company may deem appropriate and as are not inconsistent  with the provisions of
this Agreement,  or as may be required to comply with any applicable law or with
any rule or regulation  made pursuant  thereto or with any rule or regulation of
any stock  exchange  on which the Rights may from time to time be listed,  or to
conform to usage.  Subject  to the  provisions  of Section 22 hereof,  the Right
Certificates  shall  entitle the holders  thereof to purchase such number of one
one-hundredths  of a Preferred  Share as shall be set forth therein at the price
per one  one-hundredth  of a Preferred  Share set forth  therein (the  "Purchase
Price"),  but the number of such one one-hundredths of a Preferred Share and the
Purchase Price shall be subject to adjustment as provided herein.
         Section 5. Countersignature and Registration.  
The  Right  Certificates  shall be  executed  on behalf  of the  Company  by its
Chairman of the Board, its Chief Executive  Officer,  its President,  any of its
Vice Presidents,  or its Treasurer,  either manually or by facsimile  signature,
shall have affixed thereto the Company's seal or a facsimile thereof,  and shall
be attested by the  Secretary or an Assistant  Secretary of the Company,  either
manually or by facsimile signature. The Right Certificates shall be

<PAGE>

manually  countersigned  by the  Rights  Agent  and  shall  not be valid for any
purpose unless countersigned.  In case any officer of the Company who shall have
signed  any of the Right  Certificates  shall  cease to be such  officer  of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such Right Certificates,  nevertheless, may be countersigned by the
Rights  Agent and issued and  delivered  by the Company  with the same force and
effect as though the person who signed such Right Certificates had not ceased to
be such  officer  of the  Company;  and any Right  Certificate  may be signed on
behalf of the Company by any person who, at the actual date of the  execution of
such Right  Certificate,  shall be a proper  officer of the Company to sign such
Right  Certificate,  although  at the  date  of the  execution  of  this  Rights
Agreement any such person was not such an officer.
         Following the Distribution Date, the Rights Agent will keep or cause to
be kept, at its principal  office,  books for  registration  and transfer of the
Right  Certificates  issued  hereunder.  Such  books  shall  show the  names and
addresses of the  respective  holders of the Right  Certificates,  the number of
Rights  evidenced on its face by each of the Right  Certificates and the date of
each of the Right Certificates.
         Section 6. Transfer, Split Up, Combination and Exchange of Right 
Certificates:  Mutilated,  Destroyed Lost or Stolen  Right  Certificates.  
Subject to the  provisions of Section 14 hereof,  at any time after the close of
business on the  Distribution  Date, and at or prior to the close of business on
the  earlier of the  Redemption  Date or the Final  Expiration  Date,  any Right
Certificate or Right Certificates  (other than Right  Certificates  representing
Rights that have become void  pursuant to Section 11(a) (ii) hereof or that have
been  exchanged  pursuant  to Section 24 hereof) may be  transferred,  split up,
combined or  exchanged  for another  Right  Certificate  or Right  Certificates,
entitling the registered holder to purchase a like number of one  one-hundredths
of a Preferred Share as the Right Certificate or Right Certificates  surrendered
then  entitled  such  holder to  purchase.  Any  registered  holder  desiring to
transfer,  split  up,  combine  or  exchange  any  Right  Certificate  or  Right
Certificates  shall make such request in writing  delivered to the Rights Agent,
and  shall  surrender  the  Right  Certificate  or  Right   Certificates  to  be
transferred,  split up,  combined or  exchanged at the  principal  office of the
Rights Agent.  Thereupon the Rights Agent shall  countersign  and deliver to the
person entitled thereto a Right Certificate or Right Certificates, as the case

<PAGE>

may be, as so requested.  The Company may require payment of a sum sufficient to
cover any tax or governmental  charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.
         Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory  to them of the loss,  theft,  destruction or mutilation of a Right
Certificate,  and,  in case of  loss,  theft or  destruction,  of  indemnity  or
security  reasonably  satisfactory  to  them,  and,  at the  Company's  request,
reimbursement  to the Company and the Rights  Agent of all  reasonable  expenses
incidental  thereto,  and upon surrender to the Rights Agent and cancellation of
the Right  Certificate  if  mutilated,  the Company  will make and deliver a new
Right  Certificate  of like  tenor  to the  Rights  Agent  for  delivery  to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.
         Section 7. Exercise  of Rights;  Purchase Price;  Expiration Date of 
Rights.  
     (a) The registered  holder of any Right Certificate may exercise the Rights
evidenced  thereby (except as otherwise  provided herein) in whole or in part at
any time after the  Distribution  Date upon surrender of the Right  Certificate,
with the form of election to purchase on the reverse side thereof duly executed,
to the Rights Agent at the principal  office of the Rights Agent,  together with
payment of the Purchase Price for each one one-hundredth of a Preferred Share as
to which the Rights are exercised,  at or prior to the earliest of (i) the close
of business on September 18, 2008 (the "Final Expiration  Date"),  (ii) the time
at which the  Rights  are  redeemed  as  provided  in  Section  23  hereof  (the
"Redemption  Date"),  or (iii) the time at which such  Rights are  exchanged  as
provided in Section 24 hereof.
         (b) The Purchase Price for each one  one-hundredth of a Preferred Share
purchasable  pursuant to the exercise of a Right shall  initially be $1.49,  and
shall be subject to adjustment from time to time as provided in Section 11 or 13
hereof and shall be payable in lawful  money of the United  States of America in
accordance with paragraph (c) below.
         (c)  Upon  receipt  of a  Right  Certificate  representing  exercisable
Rights,  with the form of election to purchase  duly  executed,  accompanied  by
payment of the Purchase Price for the shares to be purchased and an amount equal
to any  applicable  transfer tax required to be paid by the holder of such Right
Certificate in accordance  with Section 9 hereof by certified  check,  cashier's

<PAGE>

check or money order payable to the order of the Company, the Rights Agent shall
thereupon  promptly (i) (A) requisition from any transfer agent of the Preferred
Shares  certificates  for the number of Preferred Shares to be purchased and the
Company hereby irrevocably authorizes its transfer agent to comply with all such
requests,  or (B)  requisition  from the depositary  agent  depositary  receipts
representing such number of one one-hundredths of a Preferred Share as are to be
purchased (in which case  certificates for the Preferred  Shares  represented by
such  receipts  shall be  deposited by the  transfer  agent with the  depositary
agent) and the Company hereby  directs the depositary  agent to comply with such
request, (ii) when appropriate,  requisition from the Company the amount of cash
to be paid in lieu of issuance of fractional  shares in accordance  with Section
14 hereof,  (iii) after receipt of such  certificates  or  depositary  receipts,
cause the same to be delivered to or upon the order of the registered  holder of
such Right Certificate, registered in such name or names as may be designated by
such holder and (iv) when  appropriate,  after receipt,  deliver such cash to or
upon the order of the registered holder of such Right Certificate.
         (d) In case  the  registered  holder  of any  Right  Certificate  shall
exercise less than all the Rights  evidenced  thereby,  a new Right  Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Right Certificate or to his
duly authorized assigns, subject to the provisions of Section 14 hereof.
         Section    8. Cancellation  and  Destruction  of  Right  Certificates.
All Right Certificates surrendered for the purpose of exercise,  transfer, split
up,  combination or exchange  shall,  if surrendered to the Company or to any of
its agents,  be delivered to the Rights Agent for  cancellation  or in cancelled
form, or, if  surrendered to the Rights Agent,  shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Rights Agreement.  The Company shall deliver to
the Rights Agent for cancellation and retirement,  and the Rights Agent shall so
cancel and retire,  any other  Right  Certificate  purchased  or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all  cancelled  Right  Certificates  to the  Company,  or shall,  at the written
request of the Company,  destroy such cancelled Right Certificates,  and in such
case shall deliver a certificate of destruction thereof to the Company.

<PAGE>

         Section  9.  Availability  of Preferred  Shares.  
The Company  covenants  and agrees  that it will cause to be  reserved  and kept
available out of its authorized and unissued  Preferred  Shares or any Preferred
Shares  held in its  treasury,  the  number  of  Preferred  Shares  that will be
sufficient  to  permit  the  exercise  in  full  of all  outstanding  Rights  in
accordance  with Section 7. The Company  covenants  and agrees that it will take
all  such  action  as may be  necessary  to  ensure  that all  Preferred  Shares
delivered  upon  exercise  of  Rights  shall,  at the  time of  delivery  of the
certificates  for such  Preferred  Shares  (subject  to payment of the  Purchase
Price),  be  duly  and  validly   authorized  and  issued  and  fully  paid  and
nonassessable shares.
         The Company further  covenants and agrees that it will pay when due and
payable any and all federal and state  transfer  taxes and charges  which may be
payable in respect of the issuance or delivery of the Right  Certificates  or of
any  Preferred  Shares  upon the  exercise  of Rights.  The  Company  shall not,
however,  be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right  Certificates  to a person other than,  or the
issuance or delivery of  certificates  or depositary  receipts for the Preferred
Shares  in a name  other  than  that of,  the  registered  holder  of the  Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any  certificates or depositary  receipts for Preferred Shares upon the exercise
of any  Rights  until  any such tax  shall  have  been  paid (any such tax being
payable by the holder of such Right  Certificate  at the time of  surrender)  or
until it has been established to the Company's  reasonable  satisfaction that no
such tax is due.
         Section 10.  Preferred Shares Record Date. 
Each person in whose name any  certificate  for Preferred  Shares is issued upon
the  exercise  of Rights  shall for all  purposes  be deemed to have  become the
holder  of record of the  Preferred  Shares  represented  thereby  on,  and such
certificate shall be dated, the date upon which the Right Certificate evidencing
such  Rights was duly  surrendered  and payment of the  Purchase  Price (and any
applicable transfer taxes) was made; provided, however, that if the date of such
surrender and payment is a date upon which the Preferred  Shares  transfer books
of the Company are closed, such person shall be deemed to have become the record
holder  of such  shares  on,  and  such  certificate  shall be  dated,  the next
succeeding  Business Day on which the  Preferred  Shares  transfer  books of the
Company are open.  Prior to the exercise of the Rights  evidenced  thereby,  the
holder of a Right  Certificate,  shall not be entitled to any rights of a holder
of Preferred Shares for which the Rights shall be exercisable, including,
<PAGE>

without   limitation,   the  right  to  vote,  to  receive  dividends  or  other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.
         Section  11.  Adjustment  of  Purchase  Price,  Number of Shares or 
Number of Rights. 
The Purchase Price, the number of Preferred Shares covered by each Right and the
number of Rights  outstanding  are  subject to  adjustment  from time to time as
provided in this Section 11.
         (a) (i) In the event the  Company  shall at any time  after the date of
this  Agreement  (A)  declare a  dividend  on the  Preferred  Shares  payable in
Preferred Shares,  (B) subdivide the outstanding  Preferred Shares,  (C) combine
the outstanding  Preferred  Shares into a smaller number of Preferred  Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such  reclassification  in connection with a consolidation
or merger in which the  Company is the  continuing  or  surviving  corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record  date for such  dividend or of the  effective  date of
such subdivision,  combination or  reclassification,  and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right  exercised  after such time shall be entitled to
receive the aggregate  number and kind of shares of capital stock which, if such
Right had been exercised  immediately  prior to such date and at a time when the
Preferred  Shares  transfer  books of the Company were open, he would have owned
upon such  exercise  and been  entitled  to receive by virtue of such  dividend,
subdivision,  combination or  reclassification;  provided,  however,  that in no
event shall the  consideration to be paid upon the exercise of one Right be less
than the  aggregate  par value of the  shares of  capital  stock of the  Company
issuable upon exercise of one Right.
                  (ii) Subject to Section 24 of this Agreement, in the event any
         Person  becomes  an  Acquiring  Person,  each  holder of a Right  shall
         thereafter  have a right to receive,  upon exercise  thereof at a price
         equal to the then current  Purchase  Price  multiplied by the number of
         one  one-hundredths  of a  Preferred  Share  for  which a Right is then
         exercisable, in accordance with the terms of this Agreement and in lieu
         of  Preferred  Shares,  such number of Common  Shares of the Company as
         shall equal the result  obtained by (x)  multiplying  the then  current
         Purchase Price by the number of one one-hundredths of a Preferred Share

<PAGE>

         for which a Right is then  exercisable and dividing that product by (y)
         50% of the then current per share market price of the Company's  Common
         Shares (determined pursuant to Section 11(d) hereof) on the date of the
         occurrence of such event.  In the event that any Person shall become an
         Acquiring Person and the Rights shall then be outstanding,  the Company
         shall  not take any  action  which  would  eliminate  or  diminish  the
         benefits intended to be afforded by the Rights.
                  From and after the  occurrence of such event,  any Rights that
         are or were acquired or beneficially  owned by any Acquiring Person (or
         any Associate or Affiliate of such Acquiring  Person) shall be void and
         any holder of such Rights  shall  thereafter  have no right to exercise
         such Rights under any provision of this Agreement. No Right Certificate
         shall  be  issued  pursuant  to  Section  3  that   represents   Rights
         beneficially  owned by an  Acquiring  Person whose Rights would be void
         pursuant  to the  preceding  sentence  or any  Associate  or  Affiliate
         thereof;  no Right  Certificate  shall be  issued  at any time upon the
         transfer of any Rights to an  Acquiring  Person  whose  Rights would be
         void pursuant to the  preceding  sentence or any Associate or Affiliate
         thereof  or to any  nominee  of such  Acquiring  Person,  Associate  or
         Affiliate;  and any Right Certificate delivered to the Rights Agent for
         transfer to an Acquiring  Person whose Rights would be void pursuant to
         the preceding sentence shall be cancelled.
                  (iii) In the event that there shall not be  sufficient  Common
         Shares issued but not  outstanding or authorized but unissued to permit
         the  exercise in full of the Rights in  accordance  with the  foregoing
         subparagraph  (ii),  the  Company  shall take all such action as may be
         necessary  to authorize  additional  Common  Shares for  issuance  upon
         exercise of the  Rights.  In the event the  Company  shall,  after good
         faith effort,  be unable to take all such action as may be necessary to
         authorize such additional Common Shares,  the Company shall substitute,
         for each Common Share that would otherwise be issuable upon exercise of
         a Right, a number of Preferred Shares or fraction thereof such that the
         current per share market price of one  Preferred  Share  multiplied  by
         such number or fraction is equal to the current per share  market price
         of one Common Share as of the date of issuance of such Preferred Shares
         or fraction thereof.

<PAGE>

In case the Company shall fix a record date for the issuance of rights,  options
or warrants  to all holders of  Preferred  Shares  entitling  them (for a period
expiring  within 45 calendar  days after such record date) to  subscribe  for or
purchase  Preferred  Shares (or shares  having the same rights,  privileges  and
preferences  as  the  preferred  Shares  ("equivalent   preferred  shares"))  or
securities convertible into Preferred Shares or equivalent preferred shares at a
price per Preferred Share or equivalent  preferred share (or having a conversion
price per share, if a security  convertible  into Preferred Shares or equivalent
preferred  shares)  less than the then  current  per share  market  price of the
Preferred Shares (as defined in Section 11(d)) on such record date, the Purchase
Price to be in effect after such record date shall be determined by  multiplying
the  Purchase  Price  in  effect  immediately  prior  to such  record  date by a
fraction,  the  numerator  of which  shall be the  number  of  Preferred  Shares
outstanding  on such record date plus the number of  Preferred  Shares which the
aggregate  offering  price  of the  total  number  of  Preferred  Shares  and/or
equivalent  preferred  shares so to be offered  (and/or  the  aggregate  initial
conversion price of the convertible  securities so to be offered) would purchase
at such current market price and the denominator of which shall be the number of
Preferred  Shares  outstanding on such record date plus the number of additional
Preferred  Shares  and/or   equivalent   preferred  shares  to  be  offered  for
subscription  or purchase  (or into which the  convertible  securities  so to be
offered are initially  convertible);  provided,  however, that in no event shall
the  consideration  to be paid upon the  exercise  of one Right be less than the
aggregate par value of the shares of capital stock of the Company  issuable upon
exercise  of one  Right.  In  case  such  subscription  price  may be  paid in a
consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent.  Preferred  Shares owned by or held for the account
of the  Company  shall not be deemed  outstanding  for the  purpose  of any such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued,  the  Purchase  Price shall be adjusted to be the  Purchase  Price which
would then be in effect if such record date had not been fixed.
         (c) In case the  Company  shall fix a record  date for the  making of a
distribution  to all  holders  of  the  Preferred  Shares  (including  any  such
distribution  made in  connection  with a  consolidation  or merger in which the

<PAGE>

Company  is  the   continuing  or  surviving   corporation)  of  evidences  of
indebtedness  or assets  (other  than a regular  quarterly  cash  dividend  or a
dividend  payable  in  Preferred  Shares)  or  subscription  rights or  warrants
(excluding those referred to in Section 11(b) hereof),  the Purchase Price to be
in effect after such record date shall be determined by multiplying the Purchase
Price  in  effect  immediately  prior to such  record  date by a  fraction,  the
numerator  of which  shall be the then  current  per share  market  price of the
Preferred  Shares on such record date, less the fair market value (as determined
in good faith by the Board of  Directors  of the  Company,  whose  determination
shall be described in a statement filed with the Rights Agent) of the portion of
the  assets  or  evidences  of  indebtedness  so to be  distributed  or of  such
subscription  rights  or  warrants  applicable  to one  preferred  Share and the
denominator  of which  shall  be such  current  per  share  market  price of the
preferred Shares; provided, however, that in no event shall the consideration to
be paid upon the exercise of one Right be less than the  aggregate  par value of
the shares of capital  stock of the  Company to be issued  upon  exercise of one
Right. Such adjustments  shall be made successively  whenever such a record date
is fixed;  and in the event that such  distribution is not so made, the Purchase
Price shall again be  adjusted to be the  Purchase  Price which would then be in
effect if such record date had not been fixed.
         (d) (i) For the purpose of any computation hereunder,  the "current per
share  market  price" of any  security  (a  "Security"  for the  purpose of this
Section  11(d)(ii)  on any date  shall be deemed to be the  average of the daily
closing  prices per share of such Security for the 30  consecutive  Trading Days
(as such term is hereinafter  defined) immediately prior to such date; provided,
however,  that in the  event  that the  current  per share  market  price of the
Security is determined  during a period following the announcement by the issuer
of such Security of (A) a dividend or distribution  on such Security  payable in
shares of such Security or securities  convertible into such shares,  or (B) any
subdivision,  combination or  reclassification of such Security and prior to the
expiration  of 30 Trading Days after the  ex-dividend  date for such dividend or
distribution,   or  the  record  date  for  such  subdivision,   combination  or
reclassification,  then,  and in each such case,  the current  per share  market
price shall be  appropriately  adjusted to reflect the current  market price per
share  equivalent of such Security.  The closing price for each day shall be the
last sale price  regular  way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices,  regular way, in either case as

<PAGE>

reported in the principal consolidated transaction reporting system with respect
to securities  listed or admitted to trading on the American  Stock Exchange or,
if the  Security  is not listed or  admitted  to trading on the  American  Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the  Security is listed or  admitted to trading or, if the  Security is
not listed or admitted to trading on any national securities exchange,  the last
quoted  price or, if not so  quoted,  the  average of the high bid and low asked
prices in the  over-the-counter  market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotations System ("NASDAQ") or such other
system  then in use,  or, if on any such date the  Security is not quoted by any
such organization,  the average of the closing bid and asked prices as furnished
by a professional  market maker making a market in the Security  selected by the
Board of Directors of the Company.  The term  "Trading  Day" shall mean a day on
which the principal national securities exchange on which the Security is listed
or  admitted  to  trading is open for the  transaction  of  business  or, if the
Security  is not  listed or  admitted  to  trading  on any  national  securities
exchange, a Business Day.
         (ii) For the purpose of any  computation  hereunder,  the  "current per
share market  price" of the  Preferred  Shares shall be determined in accordance
with the method set forth in Section 11(d) (i). If the Preferred  Shares are not
publicly  traded,  the "current per share market price" of the preferred  Shares
shall be  conclusively  deemed to be the current per share  market  price of the
Common  Shares as  determined  pursuant  to  Section  11(d)  (i)  (appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring  after the date  hereof),  multiplied  by one hundred.  If neither the
Common Shares nor the Preferred Shares are publicly held or so listed or traded,
"current  per  share  market  price"  shall  mean the fair  value  per  share as
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose
determination shall be described in a statement filed with the Rights Agent.
         (e) No adjustment in the Purchase  Price shall be required  unless such
adjustment  would require an increase or decrease of at least 1% in the Purchase
Price;  provided,  however, that any adjustments which by reason of this Section
11(e) are not  required  to be made  shall be  carried  forward  and taken  into
account in any subsequent  adjustment.  All  calculations  under this Section 11
shall be made to the  nearest  cent or to the  nearest  one  one-millionth  of a
Preferred Share or one ten-thousandth of any other share or security as the case
may be. Notwithstanding the first sentence of this Section 11(e), any adjustment

<PAGE>

required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the  transaction  which requires such  adjustment or (ii)
the date of the expiration of the right to exercise any Rights.
         (f) If as a result of an  adjustment  made  pursuant  to Section  11(a)
hereof,  the holder of any Right  thereafter  exercised shall become entitled to
receive any shares of capital stock of the Company other than preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right shall be subject to adjustment  from time to time in a manner and on terms
as nearly  equivalent  as  practicable  to the  provisions  with  respect to the
preferred  Shares  contained in Section  11(a) through (c),  inclusive,  and the
provisions  of Sections  7, 9, 10 and 13 with  respect to the  preferred  Shares
shall apply on like terms to any such other shares.
         (g) All  Rights  originally  issued by the  Company  subsequent  to any
adjustment  made to the Purchase  Price  hereunder  shall  evidence the right to
purchase,  at the adjusted Purchase Price, the number of one one-hundredths of a
preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.
         (h) Unless the Company shall have exercised its election as provided in
Section  11(i),  upon each  adjustment of the Purchase  Price as a result of the
calculations made in Sections 11 (b) and (c), each Right outstanding immediately
prior to the making of such adjustment  shall  thereafter  evidence the right to
purchase, at the adjusted Purchase Price, that number of one one-hundredths of a
preferred  Share  (calculated  to the nearest one  one-millionth  of a Preferred
Share)  obtained by (i) multiplying  (x) the number of one  one-hundredths  of a
share  covered  by a  Right  immediately  prior  to this  adjustment  by (y) the
Purchase Price in effect  immediately  prior to such  adjustment of the Purchase
Price and (ii) dividing the product so obtained by the Purchase  Price in effect
immediately after such adjustment of the Purchase Price.
         (i) The Company may elect on or after the date of any adjustment of the
Purchase  Price  to  adjust  the  number  of  Rights,  in  substitution  for any
adjustment in the number of one  one-hundredths of a Preferred Share purchasable
upon  the  exercise  of a  Right.  Each of the  Rights  outstanding  after  such
adjustment  of the number of Rights shall be  exercisable  for the number of one
one-hundredths   of  a  Preferred  Share  for  which  a  Right  was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the Purchase

<PAGE>

Price in effect  immediately  prior to adjustment  of the Purchase  Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights,  indicating  the record  date for the  adjustment,  and, if known at the
time, the amount of the adjustment to be made.  This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the Right
Certificates have been issued,  shall be at least 10 days later than the date of
the public  announcement.  If Right  Certificates  have been  issued,  upon each
adjustment of the number of Rights  pursuant to this Section 11(i),  the Company
shall, as promptly as practicable,  cause to be distributed to holders of record
of Right Certificates on such record date Right Certificates evidencing, subject
to Section 14  hereof,  the  additional  Rights to which such  holders  shall be
entitled as a result of such adjustment, or, at the option of the Company, shall
cause  to  be  distributed  to  such  holders  of  record  in  substitution  and
replacement for the Right Certificates held by such holders prior to the date of
adjustment,  and upon surrender thereof,  if required by the Company,  new Right
Certificates  evidencing  all the Rights to which such holders shall be entitled
after such adjustment.  Right Certificates so to be distributed shall be issued,
executed  and  countersigned  in the  manner  provided  for  herein and shall be
registered  in the names of the holders of record of Right  Certificates  on the
record date specified in the public announcement.
         (j)  Irrespective  of any adjustment or change in the Purchase Price or
the number of one one-hundredths of a Preferred Share issuable upon the exercise
of the Rights,  the Right  Certificates  theretofore  and thereafter  issued may
continue to express the Purchase Price and the number of one one-hundredths of a
Preferred  Share which were expressed in the initial Right  Certificates  issued
hereunder.
         (k) Before  taking any action that would cause an  adjustment  reducing
the Purchase Price below one one-hundredth of the then par value, if any, of the
Preferred  Shares  issuable upon exercise of the Rights,  the Company shall take
any corporate  action which may, in the opinion of its counsel,  be necessary in
Order  that  the  Company   may  validly  and  legally   issue  fully  paid  and
nonassessable Preferred Shares at such adjusted Purchase Price.
         (l) In any  case  in  which  this  Section  11  shall  require  that an
adjustment  in the  Purchase  Price be made  effective as of a record date for a

<PAGE>

specified  event,  the Company may elect to defer until the  occurrence  of such
event the issuing to the holder of any Right exercised after such record date of
the Preferred  Shares and other  capital stock or securities of the Company,  if
any,  issuable upon such exercise over and above the Preferred  Shares and other
capital stock or securities of the Company,  if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; provided,
however,  that the  Company  shall  deliver  to such  holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.
         (m) Anything in this Section 11 to the  contrary  notwithstanding,  the
Company  shall be entitled to make such  reductions  in the Purchase  Price,  in
addition to those adjustments  expressly  required by this Section 11, as and to
the extent that it in its sole  discretion  shall  determine  to be advisable in
order that any  consolidation or subdivision of the Preferred  Shares,  issuance
wholly for cash of any Preferred  Shares at less than the current  market price,
issuance wholly for cash of Preferred  Shares or securities which by their terms
are  convertible  into  or  exchangeable  for  Preferred  Shares,  dividends  on
Preferred Shares payable in Preferred  Shares or issuance of rights,  options or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares shall not be taxable to such stockholders.
         (n) In the event that at any time after the date of this  Agreement and
prior to the  Distribution  Date,  the  Company  shall  (i)  declare  or pay any
dividend  on the  Common  Shares  payable  in  Common  Shares  or (ii)  effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or otherwise  than by payment of  dividends in Common  Shares)
into a greater or lesser number of Common Shares,  then in any such case (A) the
number of one  one-hundredths  of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one  one-hundredths of a Preferred Share so purchasable  immediately prior to
such event by a fraction,  the numerator of which is the number of Common Shares
outstanding  immediately  before such event and the  denominator of which is the
number of Common Shares  outstanding  immediately after such event, and (B) each
Common  Share  outstanding  immediately  after such event shall have issued with
respect  to it that  number  of  Rights  which  each  Common  Share  outstanding
immediately  prior to such event had issued with respect to it. The  adjustments
provided for in this Section  11(n) shall be made  successively  whenever such a

<PAGE>

dividend is declared or paid or such a subdivision, combination or consolidation
is effected.
        Section 12. Certificate of Adjusted  Purchase Price or Number of Shares.
Whenever  an  adjustment  is made as  provided  in Section 11 or 13 hereof,  the
Company shall promptly (a) prepare a certificate  setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) file with
the  Rights  Agent and with each  transfer  agent for the  Common  Shares or the
Preferred Shares a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Right Certificate in accordance with Section 25 hereof.
         Section 13. Consolidation,  Merger or Sale or  Transfer  of Assets or 
Earning Power.  
In the event,  directly or indirectly,  at any time after a Person has become an
Acquiring  Person,  (a) the Company  shall  consolidate  with, or merge with and
into, any other Person,  (b) any Person shall  consolidate with the Company,  or
merge with and into the  Company  and the  Company  shall be the  continuing  or
Surviving corporation of such merger and, in connection with such merger, all or
part of the Common  Shares shall be changed into or exchanged for stock or other
securities of any other Person (or the Company) or cash or any, other  property,
or (c) the  Company  shall  sell or  otherwise  transfer  (or one or more of its
Subsidiaries  Shall sell or otherwise  transfer),  in one or more  transactions,
assets or earning power  aggregating  50% or more of the assets or earning power
of the Company and its Subsidiaries (taken as a whole) to any other Person other
than the Company or one or more of its wholly-owned  Subsidiaries,  then, and in
each such  case,  proper  provision  shall be made so that (i) each  holder of a
Right (except as otherwise  provided  herein) shall thereafter have the right to
receive, upon the exercise thereof at a price equal to the then current Purchase
Price  multiplied by the number of one  one-hundredths  of a preferred Share for
which  a Right  is then  exercisable,  in  accordance  with  the  terms  of this
Agreement and in lieu of preferred Shares,  such number of Common Shares of such
other Person  (including  the Company as successor  thereto or as the  surviving
corporation)  as shall  equal the result  obtained by (A)  multiplying  the then
current Purchase Price by the number of one  one-hundredths of a Preferred Share
for which a Right is then  exercisable  and dividing  that product by (B) 50% of
the then  current  per share  market  price of the  Common  Shares of such other
Person (determined pursuant to Section 11(d) hereof) on the date of consummation
of such consolidation,  merger, sale or transfer; (ii) the issuer of such Common
Shares shall thereafter be liable for,

<PAGE>

and shall assume, by virtue of such consolidation, merger, sale or transfer, all
the obligations and duties of the Company pursuant to this Agreement;  (iii) the
term "Company" shall thereafter be deemed to refer to such issuer; and (iv) such
issuer shall take such steps (including,  but not limited to, the reservation of
a sufficient number of its Common Shares in accordance with Section 9 hereof) in
connection  with  such  consummation  as may be  necessary  to  assure  that the
provisions  hereof shall  thereafter be applicable,  as nearly as reasonably may
be, in relation to the Common Shares thereafter deliverable upon the exercise of
the Rights.  The Company shall not  consummate any such  consolidation,  merger,
sale or transfer  unless  prior  thereto the Company and such issuer  shall have
executed  and  delivered  to  the  Rights  Agent  a  supplemental  agreement  so
providing. The Company shall not enter into any transaction of the kind referred
to in this Section 13 if at the time of such  transaction  there are any rights,
warrants,   instruments   or  securities   outstanding   or  any  agreements  or
arrangements  which, as a result of the consummation of such transaction,  would
eliminate or substantially  diminish the benefits intended to be afforded by the
Rights.  The provisions of this Section 13 shall  similarly  apply to successive
mergers or consolidations or sales or other transfers.
         Section  14.  Fractional Rights and  Fractional  Shares.  
(a) The  Company  shall  not be  required  to issue  fractions  of  Rights or to
distribute Right Certificates which evidence  fractional Rights. In lieu of such
fractional  Rights,  there shall be paid to the registered  holders of the Right
Certificates  with regard to which such  fractional  Rights  would  otherwise be
issuable,  an amount in cash equal to the same  fraction of the  current  market
value of a whole  Right.  For the  purposes of this  Section 14 (a), the current
market  value of a whole Right shall be the closing  price of the Rights for the
Trading Day immediately  prior to the date on which such fractional Rights would
have been  otherwise  issuable.  The closing price for any day shall be the last
sale price,  regular  way, or, in case no such sale takes place on such day, the
average of the  closing  bid and asked  prices,  regular  way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities  listed or admitted to trading on the American  Stock Exchange or,
if the Rights  are not listed or  admitted  to  trading  on the  American  Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the Rights are listed or  admitted to trading or, if the Rights are not
listed or  admitted to trading on any  national  securities  exchange,  the last
quoted price or, if not so quoted,

<PAGE>

the average of the high bid and low asked prices in the over-the-counter market,
as reported  by NASDAQ or such other  system then in use or, if on any such date
the Rights are not quoted by any such  organization,  the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Rights selected by the Board of Directors of the Company.  If on any such
date no such market  maker is making a market in the  Rights,  the fair value of
the Rights on such date as determined in good faith by the Board of Directors of
the Company shall be used.
         (b) The Company  shall not be required to issue  fractions of Preferred
Shares (other than fractions which are integral  multiples of one  one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute  certificates
which  evidence  fractional  Preferred  Shares (other than  fractions  which are
integral  multiples of one  one-hundredth  of a Preferred  Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may, at the  election of the  Company,  be  evidenced  by  depositary  receipts,
pursuant to an  appropriate  agreement  between  the  Company  and a  depositary
selected by it; provided,  that such agreement shall provide that the holders of
such depositary  receipts shall have all the rights,  privileges and preferences
to which  they  are  entitled  as  beneficial  owners  of the  Preferred  Shares
represented by such depositary receipts.  In lieu of fractional Preferred Shares
that are not integral  multiples of one  one-hundredth of a Preferred Share, the
Company shall pay to the registered  holders of Right  Certificates  at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share. For the purposes of
this Section 14(b),  the current market value of a Preferred  Share shall be the
closing  price of a  Preferred  Share  (as  determined  pursuant  to the  second
sentence of Section 11(d) (i) hereof) for the Trading Day  immediately  prior to
the date of such exercise.
         (c) The  holder of a Right by the  acceptance  of the  Right  expressly
waives the right to receive any fractional  Rights or any fractional shares upon
exercise of a Right (except as provided above).

<PAGE>

         Section 15. Rights of Action. 
All  rights of action in  respect  of this  Agreement,  excepting  the rights of
action  given to the Rights  Agent  under  Section 18 hereof,  are vested in the
respective  registered  holders  of the Right  Certificates  (and,  prior to the
Distribution  Date,  the  registered  holders  of the  Common  Shares);  and any
registered holder of any Right Certificate (or, prior to the Distribution  Date,
of the Common Shares),  without the consent of the Rights Agent or of the holder
of any other Right  Certificate  (or,  prior to the  Distribution  Date,  of the
Common Shares), may, in his own behalf and for his own benefit, enforce, and may
institute  and maintain any suit,  action or  proceeding  against the Company to
enforce,  or  otherwise  act in  respect  of, his right to  exercise  the Rights
evidenced  by such  Right  Certificate  in the  manner  provided  in such  Right
Certificate  and in  this  Agreement.  Without  limiting  the  foregoing  or any
remedies  available to the holders of Rights,  it is  specifically  acknowledged
that the  holders  of Rights  would not have an  adequate  remedy at law for any
breach of this  Agreement  and will be entitled to specific  performance  of the
obligations under, and injunctive relief against actual or threatened violations
of the obligations of any Person subject to, this Agreement.
     Section 16. Agreement  of Right  Holders.
Every  holder of a Right,  by accepting  the same,  consents and agrees with the
Company and the Rights Agent and with every other holder of a Right that:
     (a) prior to the Distribution Date, the Rights will be transferable only in
connection with the transfer of the Common Shares;
         (b)  after  the   Distribution   Date,  the  Right   Certificates   are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the principal  office of the Rights Agent,  duly  endorsed or  accompanied  by a
proper instrument of transfer; and
         (c) the Company  and the Rights  Agent may deem and treat the person in
whose  name the Right  Certificate  (or,  prior to the  Distribution  Date,  the
associated  Common  Shares  certificate)  is  registered  as the absolute  owner
thereof and of the Rights evidenced  thereby  (notwithstanding  any notations of
ownership or writing on the Right  Certificates or the associated  Common Shares
certificate  made by anyone other than the Company or the Rights  Agent) for all
purposes  whatsoever,  and neither  the  Company  nor the Rights  Agent shall be
affected by any notice to the contrary.

<PAGE>

         Section    17.  Right  Certificate  Holder Not Deemed a  Stockholder.  
No holder, as such, of any Right Certificate shall be entitled to vote,  receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other  securities  of the  Company  which  may at any  time be  issuable  on the
exercise of the Rights represented  thereby, nor shall anything contained herein
or in any Right  Certificate be construed to confer upon the holder of any Right
Certificate,  as such,  any of the rights of a stockholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
stockholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
stockholders  (except as provided in Section 25 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Right  Certificate  shall  have  been  exercised  in  accordance  with the
provisions hereof.
         Section  18.  Concerning  the Rights Agent. 
The Company agrees to pay to the Rights Agent  reasonable  compensation  for all
services  rendered  by it  hereunder  and,  from time to time,  on demand of the
Rights Agent, its reasonable  expenses and counsel fees and other  disbursements
incurred in the  administration and execution of this Agreement and the exercise
and  performance of its duties  hereunder.  The Company also agrees to indemnify
the Rights Agent for, and to hold it harmless against, any loss,  liability,  or
expense,  incurred without  negligence,  bad faith or willful  misconduct on the
part of the Rights  Agent,  for anything  done or omitted by the Rights Agent in
connection with the acceptance and  administration of this Agreement,  including
the costs and  expenses  of  defending  against  any claim of  liability  in the
premises.
         The Rights Agent shall be protected  and shall incur no liability  for,
or in respect of any action taken, suffered or omitted by it in connection with,
its  administration  of this Agreement in reliance upon any Right Certificate or
certificate for the Preferred Shares or Common Shares or for other securities of
the  Company,   instrument  of  assignment  or  transfer,   power  of  attorney,
endorsement,   affidavit,  letter,  notice,  direction,   consent,  certificate,
statement,  or other  paper or  document  believed by it to be genuine and to be
signed, executed and, where necessary,  verified or acknowledged,  by the proper
person or  persons,  or  otherwise  upon the  advice of  counsel as set forth in
Section 20 hereof.

<PAGE>

         Section  19.  Merger or  Consolidation or Change of Name of Rights 
Agent. 
Any corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated,  or any corporation  resulting from
any merger or  consolidation  to which the Rights Agent or any successor  Rights
Agent shall be a party, or any  corporation  succeeding to the stock transfer or
corporate trust powers of the Rights Agent or any successor Rights Agent,  shall
be the successor to the Rights Agent under this Agreement  without the execution
or  filing  of any paper or any  further  act on the part of any of the  parties
hereto;  provided,  that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at the
time such  successor  Rights Agent shall  succeed to the agency  created by this
Agreement,  any of the Right  Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the
predecessor  Rights Agent and deliver such Right  Certificates so countersigned;
and in case at that  time any of the  Right  Certificates  shall  not have  been
countersigned,   any  successor   Rights  Agent  may   countersign   such  Right
Certificates  either in the name of the predecessor  Rights Agent or in the name
of the  successor  Rights Agent;  and in all such cases such Right  Certificates
shall  have  the full  force  Provided  in the  Right  Certificates  and in this
Agreement.
         In case at any time the name of the Rights  Agent  shall be changed and
at such time any of the Right Certificates shall have been countersigned but not
delivered,  the Rights Agent may adopt the countersignature under its prior name
and deliver Right Certificates so countersigned; and in case at that time any of
the Right Certificates shall not have been  countersigned,  the Rights Agent may
countersign such Right  Certificates  either in its prior name or in its changed
name;  and in all such cases such Right  Certificates  shall have the full force
provided in the Right Certificates and in this Agreement.
         Section 20.  Duties  of Rights Agent.  
The Rights Agent undertakes the duties and obligations imposed by this Agreement
upon the  following  terms and  conditions,  by all of which the Company and the
holders of Right Certificates, by their acceptance thereof, shall be bound:
         (a) The Rights Agent may consult  with legal  counsel (who may be legal
counsel  for the  Company),  and the opinion of such  counsel  shall be full and

<PAGE>

complete authorization and protection to the Rights Agent as to any action taken
or omitted by it in good faith and in accordance with such opinion.
         (b) Whenever in the  performance of its duties under this Agreement the
Rights Agent shall deem it  necessary  or  desirable  that any fact or matter be
proved or  established  by the Company  prior to taking or suffering  any action
hereunder,  such fact or matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed)  may be deemed to be  conclusively  proved and
established  by, a  certificate  signed by any one of the Chairman of the Board,
the Chief Executive Officer, the President, any Vice President, the Treasurer or
the  Secretary  of the  Company  and  delivered  to the Rights  Agent;  and such
certificate shall be full authorization to the Rights Agent for any action taken
or  suffered  in good  faith by it under the  provisions  of this  Agreement  in
reliance upon such certificate.
         (c) The Rights  Agent shall be liable  hereunder to the Company and any
other Person only for its own negligence, bad faith or willful misconduct.
         (d) The Rights Agent shall not be liable for or by reason of any of the
statements  of fact or  recitals  contained  in this  Agreement  or in the Right
Certificates (except its countersignature  thereof) or be required to verify the
same, but all such  statements and recitals are and shall be deemed to have been
made by the Company only.
         (e) The Rights Agent shall not be under any  responsibility  in respect
of the validity of this  Agreement or the execution and delivery  hereof (except
the due  execution  hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its  countersignature  thereof);  nor
shall it be  responsible  for any  breach  by the  Company  of any  covenant  or
condition contained in this Agreement or in any Right Certificate;  nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 11(a) (ii) hereof) or any adjustment in
the terms of the  Rights  (including  the  manner,  method  or  amount  thereof)
provided  for in  Section  3,  11,  13,  23 or 24,  or the  ascertaining  of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right  Certificates  after actual
notice  that such change or  adjustment  is  required);  nor shall it by any act
hereunder  be  deemed  to  make  any   representation  or  warranty  as  to  the
authorization  or reservation of any Preferred  Shares to be issued  pursuant to
this Agreement or any Right  Certificate  or as to whether any Preferred  Shares

<PAGE>

will,  when  issued,   be  validly   authorized  and  issued,   fully  paid  and
nonassessable.
         (f) The Company agrees that it will perform,  execute,  acknowledge and
deliver or cause to be performed, executed,  acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying  out or  performing  by the Rights Agent of
the provisions of this Agreement.
         (g) The  Rights  Agent is  hereby  authorized  and  directed  to accept
instructions  with respect to the  performance of its duties  hereunder from any
one of the Chairman of the Board,  the Chief Executive  Officer,  the President,
any Vice President, the Secretary or the, Treasurer of the Company, and to apply
to such officers for advice or instructions  in connection with its duties,  and
it shall not be liable for any action  taken or  suffered by it in good faith in
accordance  with  instructions  of any such  officer  or for any delay in acting
while waiting for those instructions.
         (h) The Rights Agent and any stockholder, director, officer or employee
of the  Rights  Agent  may  buy,  sell  or deal in any of the  Rights  or  other
securities of the Company or become pecuniarily interested in any transaction in
which the  Company  may be  interested,  or  contract  with or lend money to the
Company or otherwise  act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.
         (i) The Rights  Agent may  execute  and  exercise  any of the rights or
powers hereby, vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the  Company  resulting  from any such  act,  default,
neglect or misconduct,  provided  reasonable care was exercised in the selection
and continued employment thereof.
         Section 21.  Change  of Rights Agent.  
The Rights Agent or any successor Rights Agent may resign and be discharged from
its duties under this  Agreement  upon 30 days' notice in writing  mailed to the
Company and to each transfer  agent of the Common Shares or Preferred  Shares by
registered or certified  mail, and to the holders of the Right  Certificates  by
first-class mail. The Company may remove the Rights Agent or any successor

<PAGE>

Rights  Agent upon 30 days'  notice in  writing,  mailed to the Rights  Agent or
successor  Rights Agent,  as the case may be, and to each transfer  agent of the
Common Shares or Preferred  Shares by registered or certified  mail,  and to the
holders of the Right Certificates by first-class mail. If the Rights Agent shall
resign or be removed or shall otherwise become incapable of acting,  the Company
shall appoint a successor to the Rights Agent. If the Company shall fail to make
such appointment  within a period of 30 days after giving notice of such removal
or after it has been  notified in writing of such  resignation  or incapacity by
the  resigning  or  incapacitated  Rights  Agent  or by the  holder  of a  Right
Certificate  (who shall,  with such  notice,  submit his Right  Certificate  for
inspection by the Company),  then the registered holder of any Right Certificate
may apply to any court of competent  jurisdiction  for-the  appointment of a new
Rights Agent. Any successor Rights Agent, whether appointed by the Company or by
such a court, shall be a corporation organized and doing business under the laws
of the United  States or of the State of New York (or of any other  state of the
United  States so long as such  corporation  is  authorized  to do business as a
banking institution in the State of New York, in good standing, having an office
in the State of New  York,  which is  authorized  under  such  laws to  exercise
corporate  trust or stock  transfer  powers  and is subject  to  supervision  or
examination  by  federal  or state  authority  and  which has at the time of its
appointment  as Rights  Agent a  combined  capital  and  surplus of at least $50
million. After appointment,  the successor Rights Agent shall be vested with the
same powers,  rights,  duties and  responsibilities as if it had been originally
named as Rights Agent without  further act or deed; but the  predecessor  Rights
Agent shall deliver and transfer to the  successor  Rights Agent any property at
the time held by it  hereunder,  and execute and deliver any further  assurance,
conveyance,  act or deed necessary for the purpose. Not later than the effective
date of any such  appointment  the Company shall file notice  thereof in writing
with the  predecessor  Rights Agent and each transfer agent of the Common Shares
or  Preferred  Shares,  and mail a notice  thereof in writing to the  registered
holders of the Right  Certificates.  Failure to give any notice  provided for in
this Section 21, however,  or any defect therein,  shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

<PAGE>

         Section  22. Issuance  of New Right  Certificates.  
Notwithstanding  any of the provisions of this Agreement or of the Rights to the
contrary,  the  Company  may,  at  its  option,  issue  new  Right  Certificates
evidencing  Rights in such form as may be approved by its Board of  Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other  securities  or  property  purchasable  under the Right
Certificates made in accordance with the provisions of this Agreement.
         Section 23.  Redemption.  
(a) The Board of Directors of the Company may, at its option,  at any time prior
to such time as any Person becomes an Acquiring Person,  redeem all but not less
than all the then outstanding  Rights at a redemption price of $0.001 per Right,
appropriately  adjusted to reflect any stock  split,  stock  dividend or similar
transaction  occurring  after  the date  hereof  (such  redemption  price  being
hereinafter referred to as the "Redemption Price"). The redemption of the Rights
by the Board of Directors may be made  effective at such time, on such basis and
with such  conditions  as the Board of  Directors  in its sole  discretion  may
establish.
         (b)  Immediately  upon the  action  of the  Board of  Directors  of the
Company  ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, and without any further action and without any notice,  the right to
exercise the Rights will terminate and the only right  thereafter of the holders
of Rights shall be to receive the Redemption  Price.  The Company shall promptly
give public notice of any such redemption;  provided,  however, that the failure
to give, or any defect in, any such notice shall not affect the validity of such
redemption.  Within 10 days after such action of the Board of Directors ordering
the  redemption of the Rights,  the Company shall mail a notice of redemption to
all the holders of the then  outstanding  Rights at their last addresses as they
appear upon the registry books of the Rights Agent or, prior to the Distribution
Date, on the registry  books of the transfer  agent for the Common  Shares.  Any
notice  which is mailed in the manner  herein  provided  shall be deemed  given,
whether or not the holder  receives the notice.  Each such notice of  redemption
will state the method by which the payment of the Redemption Price will be made.
Neither the Company nor any of its Affiliates or Associates may redeem,  acquire
or  purchase  for value any  Rights at any time in any  manner  other  than that
specifically  set forth in this  Section 23 or in  Section 24 hereof,  and other
than in connection with the purchase of Common Shares prior to the  Distribution
Date.

         Section 24. Exchange. 
(a) The Board of Directors of the Company may, at its option,  at any time after
any  Person  becomes  an  Acquiring  Person,  exchange  all or part of the  then
outstanding  and  exercisable  Rights (which shall not include  Rights that have
become void pursuant to the  provisions of Section 11(a) (ii) hereof) for Common
Shares  at an  exchange  ratio of one  Common  Share  per  Right,  appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring after the date hereof (such exchange ratio being hereinafter  referred
to as the  "Exchange  Ratio").  Notwithstanding  the  foregoing,  the  Board  of
Directors  shall not be empowered to effect such  exchange at any time after any
Person  (other than the Company,  any  Subsidiary  of the Company,  any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares  for or  pursuant  to the  terms of any  such  plan),  together  with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Shares then outstanding.
         (b)  Immediately  upon the  action  of the  Board of  Directors  of the
Company  ordering the exchange of any Rights  pursuant to paragraph  (a) of this
Section 24 and without any further  action and without any notice,  the right to
exercise such Rights shall  terminate and the only right  thereafter of a holder
of such Rights  shall be to receive  that number of Common  Shares  equal to the
number of such Rights held by such holder  multiplied by the Exchange Ratio. The
Company  shall  promptly  give  public  notice of any such  exchange;  provided,
however,  that the  failure to give,  or any defect in,  such  notice  shall not
affect the validity of such exchange.  The Company  promptly shall mail a notice
of any  such  exchange  to all of the  holders  of such  Rights  at  their  last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given,  whether or
not the holder receives the notice.  Each such notice of exchange will state the
method by which the  exchange  of the Common  Shares for Rights will be effected
and, in the event of any partial  exchange,  the number of Rights  which will be
exchanged.  Any partial  exchange shall be effected pro rata based on the number
of Rights (other than Rights which have become void  pursuant to the  provisions
of Section 11(a) (ii) hereof) held by each holder of Rights.
         (c) In the event  that  there  shall not be  sufficient  Common  Shares
issued but not  outstanding or authorized but unissued to permit any exchange of
Rights as  contemplated  in  accordance  with this Section 24, the Company shall

<PAGE>

take all such action as may be necessary to authorize  additional  Common Shares
for issuance upon exchange of the Rights. In the event the Company shall,  after
good faith  effort,  be unable to take all such  action as may be  necessary  to
authorize such additional Common Shares, the Company shall substitute,  for each
Common Share that would otherwise be issuable upon exchange of a Right, a number
of Preferred  Shares or fraction  thereof such that the current per share market
price of one Preferred  Share  multiplied by such number or fraction is equal to
the  current  per  share  market  price  of one  Common  Share as of the date of
issuance of such Preferred Shares or fraction thereof.
         (d) The  Company  shall not be required  to issue  fractions  of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such fractional  Common Shares,  the Company shall pay to the registered
holders of the Right  Certificates  with regard to which such fractional  Common
Shares would  otherwise be issuable an amount in cash equal to the same fraction
of the current  market value of a whole Common  Share.  For the purposes of this
paragraph  (d),  the current  market  value of a whole Common Share shall be the
closing price of a Common Share (as determined  pursuant to the second  sentence
of Section 11(d) (i) hereof) for the Trading Day  immediately  prior to the date
of exchange pursuant to this Section 24.
         Section 25.  Notice of Certain Events. 
(a) In case the Company shall  propose (i) to pay any dividend  payable in stock
of any  class to the  holders  of its  Preferred  Shares  or to make  any  other
distribution  to the  holders  of its  Preferred  Shares  (other  than a regular
quarterly cash dividend),  (ii) to offer to the holders of its Preferred  Shares
rights or warrants to  subscribe  for or to purchase  any  additional  Preferred
Shares  or  shares  of stock of any  class or any  other  securities,  rights or
options,  (iii) to effect any  reclassification  of its Preferred  Shares (other
than a reclassification  involving only the subdivision of outstanding Preferred
Shares),  (iv) to effect any  consolidation or merger into or with, or to effect
any sale or other  transfer  (or to permit  one or more of its  Subsidiaries  to
effect any sale or other transfer), in one or more transactions,  of 50% or more
of the assets or earning power of the Company and its  Subsidiaries  (taken as a
whole)  to, any other  Person,  (v) to effect the  liquidation,  dissolution  or
winding up of the Company,  or (vi) to declare or pay any dividend on the Common
Shares  payable  in Common  Shares or to effect a  subdivision,  combination  or
consolidation  of the Common Shares (by  reclassification  or otherwise  than by
payment of dividends in Common Shares), then, in each such case, the Company

<PAGE>

shall give to each holder of a Right  certificate in accordance  with Section 26
hereof,  a notice of such proposed  action,  which shall specify the record date
for the purposes of such stock dividend,  or distribution of rights or warrants,
or the  date  on  which  such  reclassification,  consolidation,  merger,  sale,
transfer, liquidation,  dissolution, or winding up is to take place and the date
of  participation  therein by the holders of the Common Shares and/or  Preferred
Shares,  if any such date is to be fixed,  and such notice  shall be so given in
the case of any  action  covered  by clause  (i) or (ii)  above at least 10 days
prior to the record date for  determining  holders of the  Preferred  Shares for
purposes of such action,  and in the case of any such other action,  at least 10
days  prior to the date of the  taking  of such  proposed  action or the date of
participation  therein  by the  holders of the Common  Shares  and/or  Preferred
Shares, whichever shall be the earlier.
         (b) In case the event set forth in  Section  11(a)  (ii)  hereof  shall
occur,  then the Company shall as soon as  practicable  thereafter  give to each
holder of a Right Certificate, in accordance with Section 26 hereof, a notice of
the  occurrence  of such event,  which notice shall  describe such event and the
consequences  of such  event to  holders  of Rights  under  Section  11 (a) (ii)
hereof.
         Section 26.  Notices.
Notices  or  demands  authorized  by this  Agreement  to be given or made by the

Shares) any legal or equitable right, remedy or claim under this Agreement;  but
this Agreement shall be for the sole and exclusive  benefit of the Company,  the
Rights Agent and the registered holders of the Right Certificates (and, prior to
the Distribution Date, the Common Shares).

                        Delaware General Corporation Law)

<PAGE>

         MEDTOX Scientific, Inc., a corporation organized and existing under the
General  Corporation  Law of the  State  of  Delaware  (hereinafter  called  the
"Corporation"),  hereby  certifies that the following  resolution was adopted by
the Board of  Directors  of the  Corporation  as  required by Section 151 of the
General Corporation Law at a meeting duly called and held on September 11, 1998:

         RESOLVED,  that pursuant to the authority  granted to and vested in the
Board of  Directors  of this  Corporation  (hereinafter  called  the  "Board  of
Directors" or the "Board") in accordance  with the provisions of the Certificate
of  Incorporation,  the Board of Directors  hereby creates a series of Preferred
Stock, par value $1.00 per share (the "Preferred Stock"), of the Corporation and
hereby  states the  designation  and number of  shares,  and fixes the  relative
rights, preferences, and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         Section  1.  Designation  and  Amount.  The shares of such series
shall be  designated  as "Series A Junior  Participating  Preferred  Stock" (the
"Series A Preferred  Stock") and the number of shares  constituting the Series A
Preferred  Stock  shall be 70,000.  Such  number of shares may be  increased  or
decreased by resolution of the Board of  Directors;  provided,  that no decrease
shall  reduce the number of shares of Series A Preferred  Stock to a number less
than the number of shares then  outstanding  plus the number of shares  reserved
for issuance  upon the exercise of  outstanding  options,  rights or warrants or
upon the  conversion of any  outstanding  securities  issued by the  Corporation
convertible into Series A Preferred Stock.

         Section 2.  Dividends and Distributions.

         (A) Subject to the rights of the holders of any shares of any series of
Preferred  Stock (or any similar stock) ranking prior and superior to the Series
A Preferred  Stock with respect to dividends,  the holders of shares of Series A
Preferred  Stock, in preference to the holders of Common Stock,  par value $0.15
per share (the  "Common  Stock"),  of the  Corporation,  and of any other junior
stock,  shall be entitled to receive,  when,  as and if declared by the Board of
Directors out of funds legally  available for the purpose,  quarterly  dividends
payable in cash on the first day of March, June,  September and December in each
year (each such date being referred to herein as a "Quarterly  Dividend  Payment
Date"),  commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction  of a share of Series A Preferred  Stock,  in an
amount per share (rounded to the nearest cent) equal to the greater of (a) $1 or
(b) subject to the provision for adjustment hereinafter set forth, 100 times the
aggregate  per share amount of all cash  dividends,  and 100 times the aggregate
per  share  amount  (payable  in  kind)  of  all  non-cash  dividends  or  other
distributions,  other  than a dividend  payable  in shares of Common  Stock or a
subdivision of the outstanding  shares of Common Stock (by  reclassification  or
otherwise),  declared  on the  Common  Stock  since  the  immediately  preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend

<PAGE>

Payment  Date,  since the first  issuance of any share or fraction of a share of
Series A Preferred Stock. In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock  payable in shares of Common  Stock,  or
effect a subdivision or combination or consolidation  of the outstanding  shares
of Common Stock (by  reclassification or otherwise than by payment of a dividend
in shares of Common  Stock) into a greater or lesser  number of shares of Common
Stock,  then in each such case the amount to which holders of shares of Series A
Preferred Stock were entitled  immediately-prior  to such event under clause (b)
of the  preceding  sentence  shall be adjusted by  multiplying  such amount by a
fraction,  the  numerator  of which is the  number of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

         (B) The  Corporation  shall declare a dividend or  distribution  on the
Series  A  Preferred  Stock   as provided  in  paragraph  (A)  of  this  Section
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or  distribution  shall have been declared on the Common Stock
during the period  between  any  Quarterly  Dividend  Payment  Date and the next
subsequent  Quarterly  Dividend  Payment Date, a dividend of $1 per share on the
Series A  Preferred  Stock  shall  nevertheless  be payable  on such  subsequent
Quarterly Dividend Payment Date.

         (C) Dividends  shall begin to accrue and be  cumulative on  outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding  the date of issue of such  shares,  unless  the date of issue of such
shares is prior to the  record  date for the first  Quarterly  Dividend  Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such  shares,  or unless the date of issue is a  Quarterly  Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Preferred  Stock entitled to receive a quarterly  dividend
and before such Quarterly  Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative  from such Quarterly  Dividend
Payment Date.  Accrued but unpaid  dividends shall not bear interest.  Dividends
paid on the shares of Series A Preferred  Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a  share-by-share  basis among all such shares at the time
outstanding.  The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred  Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

     Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

         (A) Subject to the provision for adjustment hereinafter set forth, each
share of Series A Preferred  Stock shall entitle the holder thereof to 100 votes
on all matters  submitted to a vote of the stockholders of the  Corporation.  In
the event the  corporation  shall at any time declare or pay any dividend on the
Common Stock  payable bin shares of Common  Stock,  or effect a  subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the  number of votes per share to which  holders of shares of Series A

<PAGE>

Preferred Stock were entitled  immediately prior to such event shall be adjusted
by multiplying  such number by a fraction,  the numerator of which is the number
of shares of Common  Stock  outstanding  immediately  after  such  event and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

         (B) Except as otherwise  provided herein,  in any other  Certificate of
Designations  creating a series of Preferred  Stock or any similar stock,  or by
law, the holders of shares of Series A Preferred Stock and the holders of shares
of Common Stock and any other capital stock of the  Corporation  having  general
voting  rights  shall vote  together as one class on all matters  submitted to a
vote of stockholders of the Corporation.

         (C)  Except as set  forth  herein,  or as  otherwise  provided  by law,
holders of Series A  Preferred  Stock  shall have no special  voting  rights and
their consent  shall not be required  (except to the extent they are entitled to
vote with holders of Common Stock as set forth  herein) for taking any corporate
action.

         Section 4.  Certain Restrictions.

         (A) Whenever  quarterly  dividends or other dividends or  distributions
payable on the Series A preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared,  on shares of Series A Preferred Stock  outstanding  shall have
been paid in full, the Corporation shall note

                           (i)  declare  or pay  dividends,  or make  any  other
                  distributions,  on any shares of stock ranking  junior (either
                  as to dividends or upon  liquidation,  dissolution  or winding
                  up) to the Series A Preferred Stock;

                           (ii)  declare  or pay  dividends,  or make any  other
                  distributions,  on any  shares  of stock  ranking  on a parity
                  (either as to dividends or upon  liquidation,  dissolution  or
                  winding  up)  with  the  Series  A  Preferred  Stock,   except
                  dividends paid ratably on the Series A Preferred Stock and all
                  such parity stock on which dividends are payable or in arrears
                  in proportion to the total amounts to which the holders of all
                  such shares are then entitled;

                           (iii)  redeem or  purchase or  otherwise  acquire for
                  consideration shares of any stock ranking junior (either as to
                  dividends or upon  liquidation,  dissolution or winding up) to
                  the Series A Preferred  Stock,  provided that the  Corporation
                  may at any time redeem,  purchase or otherwise  acquire shares
                  of any such junior  stock in exchange  for shares of any stock
                  of the  Corporation  ranking junior (either as to dividends or
                  upon  dissolution,  liquidation or winding up) to the Series A
                  Preferred Stock; or

                           (iv)  redeem or  purchase  or  otherwise  acquire for
                  consideration  any shares of Series A preferred  Stock, or any

<PAGE>

                  shares  of  stock  ranking  on a  parity  with  the  Series  A
                  Preferred  Stock,  except in accordance  with a purchase offer
                  made in writing or by publication  (as determined by the Board
                  of Directors) to all holders of such shares upon such terms as
                  the Board of Directors,  after consideration of the respective
                  annual   dividend   rates  and  other   relative   rights  and
                  preferences  of  the  respective  series  and  classes,  shall
                  determine  in good  faith  will  result in fair and  equitable
                  treatment among the respective series or classes.

         (B) The Corporation  shall not permit any subsidiary of the Corporation
to purchase or otherwise  acquire for  consideration  any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

         Section 5.  Reacquired  Shares.  Any shares of Series A Preferred Stock
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall be retired and cancelled promptly after the acquisition  thereof. All such
shares shall upon their  cancellation  become  authorized but unissued shares of
Preferred  Stock and may be reissued as part of a new series of Preferred  Stock
subject to the conditions and restrictions on issuance set forth herein,  in the
Certificate  of  Incorporation,  or in any  other  Certificate  of  Designations
creating  a series  of  Preferred  Stock or any  similar  stock or as  otherwise
required by law.

         Section  6.   Liquidation,   Dissolution   or  Winding   Up.  Upon  any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the  holders  of shares of stock  ranking  junior  (either  as to
dividends  or upon  liquidation,  dissolution  or  winding  up) to the  Series A
Preferred  Stock  unless,  prior  thereto,  the  holders  of  shares of Series A
Preferred  Stock shall have  received  $100 per share,  plus an amount  equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such  payment,  provided  that the  holders of shares of Series A
Preferred  Stock  shall be entitled  to receive an  aggregate  amount per share,
subject to the  provision for  adjustment  hereinafter  set forth,  equal to 100
times the aggregate  amount to be distributed  per share to holders of shares of
Common  Stock,  or (2) to the  holders  of shares of stock  ranking  on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred  Stock,  except  distributions  made  ratably on the Series A
Preferred  Stock and all such parity stock in proportion to the total amounts to
which the  holders  of all such  shares  are  entitled  upon  such  liquidation,
dissolution  or  winding  up.  In the event  the  Corporation  shall at any time
declare  or pay any  dividend  on the Common  Stock  payable in shares of Common
Stock,  or  effect  a  subdivision  or  combination  or   consolidation  of  the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock,  then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the  preceding  sentence  shall be
adjusted by multiplying  such amount by a fraction the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

         Section 7.  Consolidation,  Merger,  etc. In case the Corporation shall
enter into any consolidation,  merger, combination or other transaction in which
the shares of Common  Stock are  exchanged  for or changed  into other  stock or
securities,  cash and/or any other property, then in any such case each share of
Series A  Preferred  Stock  shall at the same  time be  similarly  exchanged  or
changed  into an amount  per  share,  subject to the  provision  for  adjustment
hereinafter  set  forth,  equal to 100  times  the  aggregate  amount  of stock,
securities,  cash and/or any other property  (payable in kind),  as the case may
be, into which or for which each share of Common Stock is changed or  exchanged.
In the event the  Corporation  shall at any time  declare or pay any dividend on
the Common Stock payable in shares of Common Stock,  or effect a subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the amount set forth in the  preceding  sentence  with  respect to the
exchange  or change of shares of Series A  Preferred  Stock shall be adjusted by
multiplying  such amount by a fraction,  the numerator of which is the number of
shares  of  Common  Stock  outstanding  immediately  after  such  event  and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

     Section 8. No Redemption.  The shares of Series A Preferred Stock shall not
be redeemable.

     Section 9. Rank. The Series A Preferred  Stock shall rank,  with respect to
the payment of dividends and the distribution of assets, junior to all series of
any other class of the Corporation's Preferred Stock.

         Section  10.  Amendment.   The  Certificate  of  Incorporation  of  the
Corporation  shall not be amended in any manner which would  materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding  shares of Series A Preferred Stock,  voting
together as a single class.

         IN WITNESS  WHEREOF,  this  Certificate of  Designations is executed on
behalf of the  Corporation  by its Chief  Executive  Officer and attested by its
Secretary this 18th day of September, 1998.
