Item 1.    Description of Registrant's Securities to be Registered.
           --------------------------------------------------------

     On November 18, 1998,  the Board of Directors of MOORE MEDICAL  CORP.  (the
"Company")  declared a dividend  distribution  of one preferred  stock  purchase
right for each outstanding share of Common Stock, par value $0.01 per share (the
"Common Stock"), of the Company held by stockholders of record on March 17, 1999
(the "Record Date").  Each Right entitles the registered holder to purchase from
the  Company  one  one-hundredth  (1/100) of a share of  preferred  stock of the
Company,  designated as Series I Junior Preferred Stock (the " Preferred Stock")
at a price  of $70 per  one  one-hundredth  (1/100)  of a share  (the  "Exercise
Price").  The  description  and  terms of the  Rights  are set forth in a Rights
Agreement (the "Rights  Agreement"),  dated as of November 18, 1998, between the
Company and  American  Stock  Transfer & Trust Co., as Rights Agent (the "Rights
Agent").

     As  discussed  below,   initially  the  rights  will  not  be  exercisable,
certificates will not be sent to stockholders and the rights will  automatically
trade with the common stock.

     The  Rights,  unless  earlier  redeemed by the Board of  Directors,  become
exercisable  upon the close of  business  on the day (the  "Distribution  Date")
which is the earlier of (i) the tenth day  following  the first date (the "Stock
Acquisition  Date")  on which  there is a public  announcement  that a person or
group of affiliated or associated  persons,  with certain  exceptions  set forth
below,  has  acquired  beneficial  ownership  of 15% or more of the  outstanding
voting  stock of the Company (an  "Acquiring  Person") or such  earlier or later
date (not  beyond the  thirtieth  day after the Stock  Acquisition  Date) as the
Board of Directors may determine and (ii) the tenth  business day (or such later
date as may be  determined  by the Board of Directors  prior to such time as any
person or group of affiliated or associated persons becomes an Acquiring Person)
after the date of the  commencement  or  announcement  of a person's  or group's
intention to commence a tender or exchange offer the consummation of which would
result in the ownership of 15% or more of the Company's outstanding voting stock
(even if no  shares  are  actually  purchased  pursuant  to such  offer);  prior
thereto,  the  Rights  will not be  exercisable,  will not be  represented  by a
separate certificate,  and will not be transferable apart from the Common Stock,
but will instead be  evidenced,  (i) with respect to any of the shares of Common
Stock held in uncertificated  book-entry form (a "Book-Entry") outstanding as of
the  Record  Date,  by such  Book-Entry  and (ii) with  respect to the shares of
Common Stock evidenced by Common Stock certificates outstanding as of the Record
Date, by such Common Stock certificate,  together with a copy of this Summary of
Rights. An Acquiring Person does not include (A) the Company, (B) any subsidiary
of the  Company,  (C) any employee  benefit  plan or employee  stock plan of the
Company  or of any  subsidiary  of the  Company,  or any  trust or other  entity
organized, appointed, established or holding Common Stock for or pursuant to the
terms of any such plan or (D) any person or group whose ownership of 15% or more
of the shares of voting stock of the Company  then  outstanding  results  solely
from (i) any action or  transaction  or  transactions  approved  by the Board of
Directors  before  such  person or group  became an  Acquiring  Person or (ii) a
reduction  in the number of  outstanding  shares of voting  stock of the Company
pursuant to a  transaction  or  transactions  approved by the Board of Directors
(provided  that any person or group that does not become an Acquiring  Person by
reason  of clause  (i) or (ii)  above  shall  become an  Acquiring  Person  upon
acquisition  of an additional  1% or more of the  Company's  voting stock unless
such  acquisition  of additional  voting stock will not result in such person or
group  becoming an Acquiring  Person by reason of such clause (i) or (ii)).  For
purposes of the  foregoing,  outstanding  voting  stock of the Company  includes
voting  stock that  trades on a "when  issued"  basis on a  national  securities
exchange or on the National  Association of Securities  Dealers,  Inc. Automated
Quotation System ("NASDAQ").

     Until the  Distribution  Date (or earlier  redemption  or expiration of the
Rights),  new Common Stock certificates issued after March 17, 1999 will contain
a legend incorporating the Rights Agreement by reference. Until the Distribution
Date (or  earlier  redemption  or  expiration  of the  Rights),  transfer on the
Company's  Direct  Registration  System of any  Common  Stock  represented  by a
Book-Entry or a certificate outstanding as of March 17, 1999, and, in each case,
with or without a copy of this  Summary of Rights  attached  thereto,  will also
constitute  the  transfer  of  the  Rights  associated  with  the  Common  Stock
represented by such Book-Entry or certificate.  As soon as practicable following
the  Distribution  Date,  separate  certificates  evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will evidence the Rights from and after the Distribution Date.

     The Rights are not exercisable until the Distribution  Date. Unless earlier
redeemed by the Company as described  below, the Rights will expire at the close
of business on March 17, 2009 (the  "Expiration  Date") (or, if the Distribution
Date shall have occurred  before March 17, 2009, at the close of business on the
90th day following the Distribution Date).

     The Preferred  Stock is  nonredeemable  and, unless  otherwise  provided in
connection  with  the  creation  of a  subsequent  series  of  preferred  stock,
subordinate to any other series of the Company's  preferred stock. The Preferred
Stock may not be issued except upon exercise of Rights.  Each share of Preferred
Stock will be entitled to receive when, as and if declared, a quarterly dividend
in an amount equal to (i) 100 times the cash dividends declared on the Company's
Common Stock,  and (ii) a preferential  cash dividend,  if any, in preference to
holders of Common Stock in an amount equal to $1.00 per share of Preferred Stock
less the per share amount of all cash dividends  declared on the Preferred Stock
pursuant  to clause  (i)  since the  immediately  preceding  quarterly  dividend
payment date. In addition, Preferred Stock is entitled to 100 times any non-cash
dividends (other than dividends  payable in equity  securities)  declared on the
Common Stock, in like kind. In the event of the liquidation of the Company,  the
holders  of  Preferred  Stock will be  entitled  to  receive,  for each share of
Preferred  Stock,  a payment  in an amount  equal to the  greater of $70 per one
one-hundredth share plus accrued and unpaid dividends and distributions  thereon
or 100 times the payment made per share of Common Stock. Each share of Preferred
Stock will have 100 votes,  voting  together with the Common Stock. In the event
of any merger,  consolidation  or other


<PAGE>

transaction  in which Common Stock is exchanged,  each share of Preferred  Stock
will be entitled to receive  100 times the amount  received  per share of Common
Stock. The rights of Preferred Stock as to dividends, liquidation and voting are
protected by anti-dilution provisions. If the dividends accrued on the Preferred
Stock for four or more quarterly dividend periods,  whether  consecutive or not,
shall not have been declared and paid or irrevocably set aside for payment,  the
holders of record of the Preferred Stock of the Company of all series (including
the  Preferred  Stock) will have the right to elect two members to the Company's
Board of Directors.

     The number of shares of  Preferred  Stock  issuable  upon  exercise  of the
Rights is  subject to  certain  adjustments  from time to time in the event of a
stock  dividend on, or a subdivision or  combination  of, the Common Stock.  The
Exercise  Price  for the  Rights  is  subject  to  adjustment  in the  event  of
extraordinary  distributions  of cash or other  property  to  holders  of Common
Stock.

     Unless the Rights are earlier  redeemed,  in the event that, after the time
that a Person becomes an Acquiring Person,  the Company were to be acquired in a
merger or other  business  combination  (in which any shares of Common Stock are
changed into or exchanged  for other  securities  or assets) or more than 50% of
the assets or earning  power of the  Company  and its  subsidiaries  (taken as a
whole)  were  to  be  sold  or  transferred  in  one  or  a  series  of  related
transactions,  the Rights Agreement  provides that proper provision will be made
so that each holder of record,  other than the Acquiring Person, of a Right will
from and after such date have the right to receive, upon payment of the Exercise
Price,  that number of shares of common stock of the acquiring  company as shall
equal the result  obtained by dividing the  Exercise  Price by 50% of the market
value of the common stock of the acquiring company.



<PAGE>


     In addition,  unless the Rights are earlier  redeemed,  in the event that a
person or group becomes an Acquiring Person,  the Rights Agreement provides that
proper  provision  will be made so that each holder of record of a Right,  other
than the Acquiring  Person (whose Rights will  thereupon  become null and void),
will thereafter  have the right to receive,  upon payment of the Exercise Price,
that number of one  one-hundredths  of a share of Preferred Stock as shall equal
the result obtained by dividing the Exercise Price by 50% of the market value of
the Preferred  Stock (such market value to be determined  with  reference to the
market value of the Company's Common Stock as provided in the Rights Agreement).

     At any time after any person or group becomes an Acquiring Person and prior
to the  acquisition  by such  person or group of 50% or more of the  outstanding
voting  stock,  the Board of  Directors  of the Company may  exchange the Rights
(other than Rights  owned by such person or group which will have become  void),
in whole or in part, at an exchange ratio of one share of Common Stock per Right
(subject to adjustment).

     Fractions of shares of  Preferred  Stock  (other than  fractions  which are
integral  multiples of one one-hundredth of a share) may, at the election of the
Company, be evidenced by depositary receipts. The Company may also issue cash in
lieu of fractional shares which are not integral  multiples of one one-hundredth
of a share.

     At any time on or prior to the close of  business on the earlier of (i) the
tenth day after the Stock  Acquisition Date (or such later date as a majority of
the Board of Directors may determine) or (ii) the  Expiration  Date, the Company
may redeem the Rights in whole,  but not in part,  at a price of $0.01 per Right
(the "Redemption  Price").  Immediately upon the effective time of the action of
the Board of Directors of the Company authorizing  redemption 


<PAGE>

of the Rights,  the right to exercise  the Rights  will  terminate  and the only
right of the holders of Rights will be to receive the Redemption Price.

     For as long as the Rights are then redeemable, the Company may, except with
respect to the redemption  price or date of expiration of the Rights,  amend the
Rights in any manner,  including an amendment to extend the time period in which
the Rights may be redeemed. At any time when the Rights are not then redeemable,
the  Company  may  amend  the  Rights in any  manner  that  does not  materially
adversely  affect the interests of holders of the Rights as such.  Amendments to
the  Rights  Agreement  from and  after  the time  that any  Person  becomes  an
Acquiring  Person and amendments to the redemption  price or expiration  date of
the Rights  require the approval of a majority of the  Continuing  Directors (as
defined and provided in the Rights Agreement).

     Until a Right is exercised,  the holder,  as such, will have no rights as a
stockholder of the Company, including,  without limitation, the right to vote or
to receive dividends.

     As of December 21, 1998 there were 3,246,030  shares of Common Stock issued
(of which  2,937,752  shares were  outstanding  and 308,270  shares were held in
treasury) and 346,575 shares reserved for issuance  pursuant to employee benefit
plans. As long as the Rights are attached to the Common Stock,  the Company will
issue one Right with each new share of Common Stock so that all such shares will
have Rights attached. The Company's Board of Directors has reserved for issuance
upon exercise of the Rights 70,000 shares of Series I Preferred Stock.

     The  Rights  Agreement  (which  includes  as  Exhibit B the forms of Rights
Certificates  and Election to Purchase and as Exhibit C the form of  Certificate
of  Designations  of Series I Junior  Preferred  Stock) is attached hereto as an
exhibit and is incorporated  herein by reference.  The foregoing  description of
the Rights is qualified in its entirety by reference to the Rights Agreement and
such exhibits thereto.

                                RIGHTS AGREEMENT

     Agreement,  dated as of November 18,  1998,  by and between  Moore  Medical
Corp., a Delaware  corporation  (the  "Company"),  and American Stock Transfer &
Trust Co. (the "Rights Agent").

                              W I T N E S S E T H:

      WHEREAS,  on November  18,  1998,  the Board of  Directors  of the Company
authorized  the issuance  of, and  declared a dividend  payable in, one right (a
"Right")  for each  share of Common  Stock,  $0.01 par value per  share,  of the
Company  outstanding  as of the close of business on March 17, 1999 (the "Record
Date"),  each such Right representing the right to purchase one one-hundredth of
a share of Series I Junior  Preferred Stock of the Company  ("Preferred  Stock")
having  the rights  and  preferences  set forth in the  Amended  Certificate  of
Designations  attached hereto as Exhibit C, authorized by the Board of Directors
on November 18, 1998,  upon the terms and subject to the conditions  hereinafter
set forth; and

     WHEREAS,  the Board of  Directors  of the Company  further  authorized  the
issuance of one Right  (subject  to  adjustment)  with  respect to each share of
Common  Stock  which may be issued  between  the Record  Date and the earlier to
occur  of the  Distribution  Date or the  Expiration  Date (as  such  terms  are
hereinafter defined);

     NOW, THEREFORE,  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 shall have the meanings indicated:

<PAGE>

     (a)  "Acquiring  Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates (as such term is hereinafter
defined) and Associates (as such term is hereinafter defined) of such Person, is
the Beneficial Owner (as such term is hereinafter defined) of 15% or more of the
Voting  Stock  (as  such  term  is  hereinafter  defined)  of the  Company  then
outstanding; provided, that, an Acquiring Person shall not include (i) an Exempt
Person (as such term is hereinafter  defined) or (ii) any Person,  together with
all Affiliates and Associates of such Person, who or which would be an Acquiring
Person  solely by reason of (A) being the  Beneficial  Owner of shares of Voting
Stock of the Company then  outstanding,  the  Beneficial  Ownership of which was
acquired  by  such   Person  (or  his  or  its   predecessor   through   merger,
consolidation,  amalgamation or other similar legal succession)  pursuant to any
action or transaction or series of related actions or  transactions  approved by
the Board of Directors  before such Person  otherwise became an Acquiring Person
or (B) a reduction  in the number of  outstanding  shares of Voting Stock of the
Company pursuant to a transaction or a series of related  transactions  approved
by the Board of Directors of the Company;  provided,  further, that in the event
such Person described in this clause (ii) does not become an Acquiring Person by
reason of  subclause  (A) or (B) of this clause  (ii),  such Person  nonetheless
shall become an Acquiring  Person in the event such Person  thereafter  acquires
Beneficial  Ownership  of an  additional  1% or more of the Voting  Stock of the
Company then outstanding, unless the acquisition of such additional Voting Stock
would not  result  in such  Person  becoming  an  Acquiring  Person by reason of
subclause (A) or (B) of this clause (ii).  Notwithstanding the foregoing, if the
Board of  Directors  of the Company  determines  in good faith that a Person who
would  otherwise be an "Acquiring  Person" as 

<PAGE>

defined  pursuant to the foregoing  provisions of this  paragraph (a) has become
such  inadvertently,  and such Person  divests as promptly  as  practicable  (as
determined  in good  faith by the Board of  Directors)  a  sufficient  number of
shares of  Common  Stock 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 an  "Acquiring  Person" for any purposes of
this Rights Agreement.

     (b) "Affiliate"  shall have the meaning ascribed to such term in Rule 12b-2
of the General Rules and Regulations under the Securities  Exchange Act of 1934,
as amended ("Exchange Act"), as in effect on the date of this Rights Agreement.

     (c)  "Associate"  of a Person (as such term is  hereinafter  defined) shall
mean (i) with respect to a  corporation,  any officer or director  thereof or of
any Subsidiary (as such term is hereinafter  defined) thereof, or any Beneficial
Owner  (as such  term is  hereinafter  defined)  of 10% or more of any  class of
equity security thereof, (ii) with respect to an association,  joint venture, or
other  unincorporated  organization,  any  officer or  director  thereof or of a
Subsidiary  thereof or any Beneficial Owner of a 10% or more ownership  interest
therein, (iii) with respect to a partnership, any general partner thereof or any
limited partner thereof who is, directly or indirectly,  the Beneficial Owner of

     dated as of November 18, 1998,  as it may be amended from time to time (the
     "Rights  Agreement"),  the  terms  of  which  are  incorporated  herein  by
     reference and a copy of which is on file at the principal executive offices
     of the Company.  Under  certain  circumstances,  as set forth in the Rights
     Agreement,  such Rights  shall be evidenced  by separate  certificates  and
     shall no longer be evidenced by this certificate. The Company shall mail to
     the registered  holder of this  certificate a copy of the Rights  Agreement
     without  charge  within  five  days  after  receipt  of a  written  request

<PAGE>


      RIGHTS  ISSUED TO OR  BENEFICIALLY  OWNED BY  ACQUIRING  PERSONS  OR THEIR
      AFFILIATES  OR  ASSOCIATES  (AS  SUCH  TERMS  ARE  DEFINED  IN THE  RIGHTS
      AGREEMENT) OR ANY SUBSEQUENT  HOLDER OF SUCH RIGHTS SHALL BE NULL AND VOID
      AND MAY NOT BE TRANSFERRED TO ANY PERSON.

     (d) As soon as practicable  after the  Distribution  Date, the Company will

of the Close of Business on the  Distribution  Date,  as shown by the records of
the Company,  at the address of such holder shown on such records, a certificate
in the form  provided by Section 4 hereof (a "Rights  Certificate"),  evidencing
one Right  (subject to adjustment  as provided  herein) for each share of Common
Stock so held.  As of and after  the  Distribution  Date,  the  Rights  shall be
evidenced  solely by such  Rights  Certificates  and may be  transferred  by the
transfer of the Rights  Certificate  as permitted  hereby,  separately and apart
from any transfer of one or more shares of Common Stock.

     (e) In  addition,  in  connection  with the  issuance  or sale of shares of
Common Stock following the  Distribution  Date and prior to the Expiration Date,
the Company (i) shall,  with respect to shares of Common Stock so issued or sold
(x)  pursuant to the  exercise of stock  options or under any  employee  plan or
arrangement or (y) upon the exercise, conversion or exchange of other securities
issued by the Company prior to the Distribution  Date and (ii) may, in any other
case,  if deemed  necessary  or  appropriate  by the Board of  Directors  of the
Company, issue Rights Certificates representing the appropriate number of Rights
in  connection  with  such  issuance  or  sale;  provided  that no  such  Rights
Certificate shall be issued if, and to the extent that, (i) the Company shall be
advised  by  counsel  that such  issuance  would  create a  significant  risk of
material  adverse  tax  consequences  to the  Company or the Person to 

<PAGE>


whom such  Rights  Certificate  would be issued or (ii)  appropriate  adjustment
shall otherwise have been made in lieu of the issuance thereof.

     Section 4.  Form of Rights Certificates.

     (a) The Rights  Certificates (and the forms of election to purchase shares,
certificate and assignment to be printed on the reverse  thereof),  when, as and
if issued,  shall be substantially in the form set forth in Exhibit B hereto and
may have such marks of identification or designation and such legends, summaries
or  endorsements  printed  thereon as may be  required to comply with any law or
with any rule or regulation made pursuant thereto or with any rule or regulation
of any stock  exchange on which the Common  Stock or the Rights may from time to
time be listed or as the  Company  may deem  appropriate  to conform to usage or
otherwise  and as are not  inconsistent  with  the  provisions  of  this  Rights
Agreement.  Subject to the provisions of Section 22 hereof,  Rights Certificates
evidencing Rights whenever issued, (i) shall be dated as of the date of issuance
of the Rights they represent and (ii) subject to adjustment from time to time as
provided  herein,  on their face shall  entitle the holders  thereof to purchase
such number of shares (including  fractional shares which are integral multiples
of one-hundredth of a share) of Preferred Stock as shall be set forth therein at
the price  payable upon  exercise of a Right  provided by Section 7(b) hereof as
the same may from time to time be  adjusted as  provided  herein (the  "Exercise
Price").

     (b)  Notwithstanding  any other  provision  of this Rights  Agreement,  any
Rights  Certificate that represents  Rights  beneficially  owned by an Acquiring
Person or any  Affiliate or  Associate  thereof or any other Person whose Rights
shall become void pursuant to Section 7(e) shall have  impressed on, printed on,
written on or  otherwise  affixed to it (if the 

<PAGE>

Company or the  Rights  Agent has  knowledge  that such  Person is an  Acquiring
Person or an Associate or  Affiliate or a nominee of any of the  foregoing)  the
following legend:

         The  Beneficial  Owner  of  the  Rights   represented  by  this  Rights
     Certificate  is an  Acquiring  Person or an Affiliate or an Associate of an
     Acquiring  Person.  Accordingly,  this  Rights  Certificate  and the Rights
     represented  hereby  shall  become void in the  circumstances  specified in
     Section 7(e) of the Rights Agreement.

     Section 5.  Countersignature and Registration.

     (a) Each Rights  Certificate  shall be executed on behalf of the Company by
its Chairman of the Board,  President or any Vice President,  either manually or
by  facsimile  signature,  and have  affixed  thereto  the  Company's  seal or a
facsimile  thereof  which  shall be attested by the  Secretary  or an  Assistant
Secretary of the Company, either manually or by facsimile signature. Each Rights
Certificate  shall be  countersigned  by the Rights Agent either  manually or by
facsimile   signature  and  shall  not  be  valid  for  any  purpose  unless  so
countersigned.  In case any  officer of the  Company  who shall have  signed any
Rights  Certificate  shall  cease  to be  such  officer  of the  Company  before
countersignature   by  the  Rights  Agent  and  issuance  and  delivery  of  the
certificate  by the  Company,  such  Rights  Certificate,  nevertheless,  may be
countersigned  by the Rights Agent and issued and delivered  with the same force
and effect as though the person who  signed  such  Rights  Certificates  had not
ceased to be such officer of the Company.  Any Rights  Certificate may be signed
on behalf of the Company by any person who, on the date of the execution of such
Rights Certificate, shall be a proper officer of the Company to sign such Rights
Certificate,  although at the date of the execution of this Rights Agreement any
such person was not such an officer.

<PAGE>

     (b) Following the Distribution Date, the Rights Agent will keep or cause to
be kept,  at its  principal  office  or one or more  offices  designated  as the
appropriate  place for the  surrender of Rights  Certificates  upon  exercise or
transfer,  and in such other  locations  as may be  required  by law,  books for
registration  and transfer of the Rights  Certificates  issued  hereunder.  Such
books shall show the names and addresses of the respective holders of the Rights
Certificates,  the number of Rights  evidenced on its face by each of the Rights
Certificates,  the  date of  each  of the  Rights  Certificates  and any  Rights
Certificates that have a legend printed thereon pursuant to Section 4(b).

     Section  6.  Transfer,   Split  Up,  Combination  and  Exchange  of  Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

     (a) Subject to the provisions of Sections 7(e),  7(f) and 14(b) hereof,  at
any time after the Close of Business on the  Distribution  Date, and at or prior
to the Close of Business on the Expiration Date, any Rights Certificate,  may be
(i)  transferred  or (ii) split up,  combined or exchanged for one or more other
Rights  Certificates,  entitling the registered holder to purchase a like number
of shares of Preferred  Stock as the Rights  Certificate or Rights  Certificates
surrendered  then  entitled  such  holder to  purchase.  Any  registered  holder
desiring  to  transfer  any  Rights   Certificate  shall  surrender  the  Rights
Certificate  at the office of the Rights Agent  designated  for the surrender of
Rights  Certificates  with the form of certificate and assignment on the reverse
side thereof duly endorsed (or enclosed  with such Rights  Certificate a written
instrument  of  transfer  in form  satisfactory  to the  Company  and the Rights
Agent),  duly  executed by the  registered  holder  thereof or his attorney duly
authorized in writing,  and with such signature duly guaranteed.  Any registered
holder  desiring to split up, combine or exchange any Rights  Certificate  shall
make such request in writing  delivered to the 

<PAGE>

Rights  Agent,  and  shall  surrender  the  Rights  Certificate  to be split up,
combined or exchanged at the office of the Rights Agent.  Thereupon,  the Rights
Agent  shall  countersign  and deliver to the person  entitled  thereto a Rights
Certificate  or Rights  Certificates,  as the case may be, as so requested.  The
Company may require  payment of a sum  sufficient to cover any Transfer Tax that
may be  imposed  in  connection  with any  transfer,  split up,  combination  or
exchange of any Rights Certificates.

     (b) Subject to the provisions of Section 7(e), 7(f) and 14(b) hereof,  upon
receipt by the Company and the Rights Agent of evidence reasonably  satisfactory
to them of the loss, theft,  destruction or mutilation of a Rights  Certificate,
and, in case of loss, theft or destruction,  of indemnity or security reasonably
satisfactory  to them and, if  requested by the  Company,  reimbursement  to the
Company and the Rights Agent of all reasonable  expenses  incidental thereto, or
upon surrender to the Rights Agent and cancellation of the Rights Certificate if
mutilated,  the Company shall issue and deliver a new Rights Certificate of like
tenor to the Rights  Agent for delivery to the  registered  owner in lieu of the
Rights Certificate so lost, stolen, destroyed or mutilated.

     Section 7.  Exercise of Rights; Exercise Price; Expiration Date of Rights.

subject  to  adjustment  as  hereinafter  provided,  at or prior to the Close of
Business on the earlier of (i) March 17, 2009 (or if the Distribution Date shall
have  occurred  before March 17, 2009,  at the Close of Business on the 90th day
following  the  Distribution  Date) or (ii) the date on  which  the  Rights  are
redeemed  as  provided  in Section 23 hereof  (such  earlier  date being  herein
referred to as the "Expiration Date").

     (b) The Exercise  Price shall  initially be $70 for each one  one-hundredth
(1/100) of a share of  Preferred  Stock  issued  pursuant  to the  exercise of a
Right.  The Exercise Price and the number of shares of Preferred  Stock or other
securities  to be  acquired  upon  exercise  of a  Right  shall  be  subject  to
adjustment  from time to time as  provided  in  Sections  11 and 13 hereof.  The
Exercise Price shall be payable in lawful money of the United States of America,
in accordance with paragraph (c) below.

     (c)  Except  as  otherwise  provided  herein,  upon  receipt  of  a  Rights
Certificate  representing  exercisable  Rights  with  the  form of  election  to
purchase duly  executed,  accompanied by payment by certified  check,  cashier's
check,  bank draft or money order  payable to the Company or the Rights Agent of
the  Exercise  Price for the shares to be  purchased  and an amount equal to any
applicable  Transfer  Tax  required  to be  paid  by the  holder  of the  Rights
Certificate  in  accordance  with Section  9(e)  hereof,  the Rights Agent shall
thereupon  promptly (i) requisition from any registrar or transfer agent, as may
be appropriate,  of the Preferred Stock of the Company one or more  certificates
representing the number of shares of Preferred Stock to be so purchased, and the
Company hereby authorizes and directs such registrar or transfer agent to comply
with all such requests,  (ii) as provided in Section  14(b),  at the election of
the Company, cause depositary receipts to be issued in lieu 


<PAGE>

of fractional  shares of Preferred Stock,  (iii) if the election provided for in
the immediately  preceding  clause (ii) has not been made,  requisition from the
Company  the  amount of cash to be paid in lieu of the  issuance  of  fractional
shares in  accordance  with Section  14(b)  hereof,  (iv) after  receipt of such
Preferred Stock certificates and, if applicable,  depositary receipts, cause the
same to be  delivered  to or upon the  order of the  registered  holder  of such
Rights  Certificate,  registered  in such name or names as may be  designated by
such holder and (v) when appropriate,  after receipt, promptly deliver such cash
to or upon the  order  of the  registered  holder  of such  Rights  Certificate;
provided,  however,  that in the case of a purchase  of  securities,  other than
Preferred Stock,  pursuant to Section 13 hereof, the Rights Agent shall promptly
take the appropriate  actions  corresponding in such case to that referred to in
the foregoing clauses (i) through (v) of this Section 7(c).  Notwithstanding the
foregoing  provisions of this Section 7(c), the Company may suspend the issuance
of shares of Preferred  Stock upon exercise of a Right for a reasonable  period,
not in excess of 120 days,  during which the Company seeks to register under the
Securities Act of 1933, as amended (the "Act"),  and any  applicable  securities
law of any  other  jurisdiction,  the  shares  of  Preferred  Stock to be issued
pursuant  to the Rights;  provided,  however,  that  nothing  contained  in this
Section 7(c) shall  relieve the Company of its  obligations  under  Section 9(c)
hereof.

     (d) In case the registered holder of any Rights  Certificate shall exercise
less than all the Rights evidenced thereby, a new Rights Certificate  evidencing
Rights  equivalent to the Rights  remaining  unexercised  shall be issued by the
Rights Agent to the registered holder of such Rights  Certificate or his assign,
subject to the provisions of Section 14(b) hereof.

     (e) Notwithstanding any provision of this Rights Agreement to the contrary,
from and after the time (the "invalidation  time") when any Person first becomes
an  Acquiring  

<PAGE>

Person,  any Rights that are beneficially owned by (x) such Acquiring Person (or
any Associate or Affiliate of such Acquiring  Person),  (y) a transferee of such
Acquiring  Person (or any such  Associate or Affiliate) who becomes a transferee
after the invalidation time or (z) a transferee of such Acquiring Person (or any
such Associate or Affiliate) who becomes a transferee  prior to or  concurrently
with the invalidation  time pursuant to either (I) a transfer from the Acquiring
Person to holders of its equity securities or to any Person with whom it has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (II) a transfer which the Board of Directors has determined is part of
a plan, arrangement or understanding which has the purpose or effect of avoiding
the provisions of this Section 7(e),  and subsequent  transferees of the Persons
referred to in either clause (y) or (z) above, shall be void without any further
action and any holder of such Rights shall thereafter have no rights  whatsoever
with respect to such Rights under any  provision of this Rights  Agreement.  The
Company shall use all  reasonable  efforts to ensure that the provisions of this
Section 7(e) are complied  with,  but shall have no liability to any holder of a
Rights  Certificate or any other Person as a result of the Company's  failure to
make any  determination  with respect to an Acquiring  Person or its Affiliates,
Associates  or  transferees  hereunder.  No Rights  Certificate  shall be issued
pursuant to Section 3 hereof that  represents  Rights  beneficially  owned by an
Acquiring  Person or any other Person whose Rights would be void pursuant to the
provisions of this Section 7(e) or any Associate,  Affiliate or nominee thereof;
no Rights  Certificate  shall be issued  at any time  upon the  transfer  of any
Rights to an  Acquiring  Person or any other  Person  whose Rights would be void
pursuant to the provisions of this Section 7(e) or any  Associate,  Affiliate or
nominee thereof;  and any Rights  Certificate  delivered to the Rights 


<PAGE>

Agent for transfer to an Acquiring Person whose Rights would be void pursuant to
the provisions of this Section 7(e) shall be canceled.

     (f) Notwithstanding anything in this Agreement to the contrary, neither the
Rights Agent nor the Company  shall be  obligated  to undertake  any action with
respect to a registered holder upon the occurrence of any purported  exercise as
set  forth in this  Section  7 unless  such  registered  holder  shall  have (i)
completed and signed the certificate  following the form of election to purchase
set forth on the reverse  side of the Rights  Certificate  surrendered  for such
exercise  and (ii)  provided  such  additional  evidence of the  identity of the
Beneficial  Owner (or  former  Beneficial  Owner) or  Affiliates  or  Associates
thereof or a Person  referred  to in clause (y) or (z) of Section  7(e) and such
other information as the Company shall reasonably request.

     Section 8. Cancellation and Destruction of Rights Certificates.  All Rights
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 canceled form,
or, if surrendered  to the Rights Agent,  shall be canceled by it, and no Rights
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 cancel
and  retire,  any  Rights  Certificate  purchased  or  acquired  by the  Company
otherwise  than upon the exercise  thereof.  The Rights Agent shall  deliver all
canceled Rights Certificates to the Company, or shall, at the written request of
the Company,  destroy such canceled Rights Certificates,  and in such case shall
deliver a certificate of destruction thereof to the Company.

     Section 9.  Reservation and Availability of Shares of Preferred Stock.

     (a) The Company  covenants and agrees that it will cause to be reserved and
kept available out of its authorized and unissued  shares of Preferred  Stock or
out of  authorized  and issued  shares of Preferred  Stock held in its treasury,
such number of shares of Preferred Stock as will from time to time be sufficient
to permit the exercise in full of all outstanding Rights. The Company shall take
such action as may be required for it to comply with the  foregoing  sentence of
this Section 9(a).

     (b) The Company  shall use its best  efforts to cause,  from and after such
time as the Rights become  exercisable,  all shares of Preferred Stock issued or
reserved for  issuance in  accordance  with this Rights  Agreement to be listed,
upon  official  notice  of  issuance,  upon the  principal  national  securities
exchange,  if any,  upon which the Common  Stock is listed or, if the  principal
market for the Common Stock is not on any national  securities  exchange,  to be
eligible for  quotation on NASDAQ or any successor  thereto or other  comparable
quotation system.

     (c) The Company  covenants  and agrees that it will take all such action as
may be  necessary to insure that all shares of Preferred  Stock  delivered  upon
exercise of Rights shall, at the time of delivery of the certificates,  for such
shares  (subject to payment of the Exercise Price in respect  thereof),  be duly
and validly authorized and issued and fully paid and nonassessable shares.

     (d) The  Company  shall  use  its  best  efforts  to (i)  file,  as soon as
practicable   following  the  occurrence  of  the  event  described  in  Section
11(a)(ii),  or as soon as is required by law following the Distribution Date, as
the case may be, a  registration  statement  under the Act,  with respect to the
shares  of  Preferred  Stock  purchasable  upon  exercise  of the  Rights  on 


<PAGE>

an appropriate form, (ii) cause such registration  statement to become effective
as soon as  practicable  after such  filing,  and (iii) cause such  registration
statement  to remain  effective  (with a  prospectus  at all times  meeting  the
requirements  of the Act)  until  the  earlier  of (A) the date as of which  the
Rights are no longer  exercisable  for Preferred  Stock,  and (B) the Expiration
Date. The Company may  temporarily  suspend,  for a period of time not to exceed
120 days, the issuance of shares of Preferred  Stock upon exercise of a Right in
order to prepare and file a registration  statement  under the Act and permit it
to  become  effective.  The  Company  will  also  take  such  action  as  may be
appropriate  under, or to ensure  compliance  with, the securities or "blue sky"
laws of the various states in connection with the  exercisability of the Rights.
Notwithstanding  any  provision of this  Agreement to the  contrary,  the Rights
shall not be exercisable in any jurisdiction unless the requisite  qualification
in such jurisdiction shall have been obtained and until a registration statement
under the Act (if required) shall have been declared effective.

     (e) The Company  covenants and agrees that it will pay when due and payable
any and all federal and state  Transfer Taxes which may be payable in respect of
the original issuance or delivery of the Rights Certificates or of any shares of
Preferred  Stock  issued or delivered  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 a Rights  Certificate  to a Person other
than,  or the  issuance or delivery of  certificates  for  Preferred  Stock upon
exercise  of Rights in a name other than that of, the  registered  holder of the
Rights Certificate, and the Company shall not be required to or issue or deliver
a Rights  Certificate or certificate  for Preferred Stock to a Person other than
such  registered  holder  until any such  Transfer Tax shall have been paid (any
such Transfer Tax being payable by the 

<PAGE>

holder of such Rights Certificate at the time of surrender) or until it has been
established to the Company's satisfaction that no such Transfer Tax is due.

     Section 10.  Preferred  Stock  Record  Date.  Each Person in whose name any
certificate  for shares of Preferred Stock is issued upon the exercise of Rights
shall for all  purposes  be deemed to have  become  the  holder of record of the
Preferred Stock  represented  thereby on, and such certificate shall be dated as
of, the date upon which the Rights  Certificate  evidencing such Rights was duly
surrendered  and  payment of the  Exercise  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  Stock  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 as of,  the next  succeeding
Business  Day on which the  Preferred  Stock  transfer  books of the Company are
open.  Prior to the exercise of the Rights  evidenced  thereby,  the holder of a
Rights  Certificate,  as  such,  shall  not  be  entitled  to  any  rights  of a
stockholder  of the Company with respect to shares for which the Rights shall be
exercisable,  including,  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 Exercise Price or Number of Shares.  The Exercise
Price and the number of shares of Preferred  Stock which may be  purchased  upon
exercise  of a Right  and the  number  of  Rights  outstanding  are  subject  to
adjustment from time to time as provided in this Section 11.

<PAGE>


         (a) (i) In the event the  Company  shall at any time  after the date of
         this Rights  Agreement  (A) declare or pay any dividend on Common Stock
         payable  in  shares  of  Common  Stock,  (B)  subdivide  or  split  the
         outstanding  shares of Common Stock into a greater  number of shares or
         (C) combine or consolidate the outstanding  shares of Common Stock into
         a smaller number of shares or effect a reverse split of the outstanding
         shares  of Common  Stock,  then and in each  such  event the  number of
         shares of Preferred  Stock  issuable upon the exercise of a Right after
         the record date for such event (if one shall have been  established or,
         if not,  after the date of such event) shall be the number of shares of
         Preferred Stock issuable  immediately prior to such event multiplied by
         a fraction the  numerator of which is the number of Rights  outstanding
         immediately  prior to such  event and the  denominator  of which is the
         number of  Rights  outstanding  immediately  after  such  event and the
         Exercise  Price after such date shall be the  Exercise  Price in effect
         immediately  prior to such event  multiplied  by such  fraction.  If an
         event occurs which would require an adjustment  under both this Section
         11(a)(i) and Section 11(a)(ii) hereof,  the adjustment  provided for in
         this Section  11(a)(i) shall be in addition to, and shall be made prior
         to, any adjustment required pursuant to Section 11(a)(ii).

             (ii) Subject to Section 27 of this Agreement, in the event that any
         Person  (other  than an  Exempt  Person),  alone or  together  with its
         Affiliates  and  Associates,  shall become an Acquiring  Person,  then,
         subject to the last  sentence of Section  23(a) and except as otherwise
         provided in this Section 11, each holder 

<PAGE>

         of a Right, except as provided in Section 7(e) hereof, shall thereafter
         have the right to receive  upon  exercise  of such Right in  accordance
         with the terms of this Rights  Agreement  and  payment of the  Exercise
         Price, the greater of (1) the number of one  one-hundredths  of a share
         of  Preferred  Stock for which such Right was  exercisable  immediately
         prior to the first  occurrence  of the event  described in this Section
         11(a)(ii)  or (2)  such  number  of one  one-hundredths  of a share  of
         Preferred  Stock as shall equal the result  obtained  by  dividing  the
         Exercise Price by 50% of the Fair Market Value of one one-hundreth of a
         share of Preferred Stock (determined  pursuant to Section 11(b) hereof)
         on the date of such first occurrence;  provided,  however,  that if the
         transaction that would otherwise give rise to the foregoing  adjustment
         is also subject to the  provisions of Section 13 hereof,  then only the
         provisions of Section 13 hereof shall apply and no adjustment  shall be
         made pursuant to this Section 11(a)(ii).

             (iii) In the  event  that  the  Company  does  not  have  available
         sufficient  authorized  but  unissued  Preferred  Stock to  permit  the
         adjustments required pursuant to the foregoing  subparagraph (i) or 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  and  reserve  for  issuance  such  number  of
         additional  shares  of  Preferred  Stock  as may  from  time to time be
         required to be issued upon the exercise in full of all Rights from time
         to time  outstanding  and, if necessary,  shall use its best efforts to
         obtain  stockholder  approval  thereof.  In lieu of  issuing  shares of
         Preferred Stock in accordance with 


<PAGE>

         the foregoing subparagraphs (i) and (ii), the Company may, if the Board
         of Directors  determines  that such action is necessary or  appropriate
         and not contrary to the interests of holders of Rights,  elect to issue
         or pay,  upon the  exercise of the Rights,  cash,  property,  shares of
         Preferred or Common Stock, debt securities, or any combination thereof,
         having an aggregate Fair Market Value equal to the Fair Market Value of
         the shares of Preferred  Stock which otherwise would have been issuable
         pursuant  to  Section  11(a)(ii),  which  Fair  Market  Value  shall be
         determined  by an  investment  banking  firm  selected  by the Board of
         Directors.  For  purposes of the  preceding  sentence,  the Fair Market
         Value of the Preferred Stock shall be as determined pursuant to Section
         11(b).  Subject to Section 23 hereof, any such election by the Board of
         Directors  of the Company must be made and  publicly  announced  within
         thirty (30) days after the date on which the event described in Section
         11(a)(ii) occurs.

     (b) For the purpose of this Rights  Agreement,  the "Fair Market  Value" of
any share of  Preferred  Stock,  Common Stock or any other stock or any Right or
other security or any other property on any date shall be determined as provided
in this Section 11(b). In the case of a publicly-traded stock or other security,
the Fair Market Value on any date shall be deemed to be the average of the daily
closing  prices per share of such stock or per unit of such other  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
Fair Market Value per share of any share of Common Stock is determined  during a
period  which  includes  any date that is within 30  Trading  Days after (i) the
ex-dividend  date for a dividend or distribution on such stock payable in shares
of Common Stock or securities  convertible  into 


<PAGE>

shares of Common Stock,  or (ii) the effective date of any  subdivision,  split,
combination,  consolidation,  reverse  stock split or  reclassification  of such
stock, then, and in each such case, the Fair Market Value shall be appropriately
adjusted  by the  Board  of  Directors  of the  Company  to  take  into  account
ex-dividend or post-effective date trading.  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  applicable  transaction  reporting  system with
respect  to  securities  listed or  admitted  to  trading  on the New York Stock
Exchange),  or, if the  securities  are not listed or admitted to trading on the
New York Stock  Exchange,  as reported in the applicable  transaction  reporting
system with respect to securities  listed on the principal  national  securities
exchange on which such  security  is listed or  admitted to trading;  or, if 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 NASDAQ or such other
system  then in use;  or, if no bids for such  security  are  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 such 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 such security is listed or
admitted to trading is open for the transaction of business or, if such security
is not listed or  admitted to trading on any  national  securities  exchange,  a
Business  Day.  If a security is not  publicly  held or not so listed or traded,
"Fair  Market  Value"  shall mean the fair value per share of stock or per other
unit of such  other  security,  as  determined  by an  investment  banking  firm
experienced  in the valuation of securities  selected in 


<PAGE>

good faith by the Board of Directors of the Company,  or, if no such  investment
banking firm is, in the good faith judgment of the Board of Directors, available
to make  such  determination,  in good  faith by the Board of  Directors  of the
Company; provided,  however, that for purposes of making the adjustment provided
for by Section 11(a)(ii)  hereof,  the Fair Market Value of a share of Preferred
Stock shall not be less than 100% of the  product of the Fair Market  Value of a
share of Common Stock multiplied by the higher of the then Dividend  Multiple or
Vote Multiple applicable to the Preferred Stock (as defined in the provisions of
the Amended  Certificate of  Designations  relating to the Preferred  Stock) and
shall not exceed 105% of the product of the then Fair Market Value of a share of
Common  Stock  multiplied  by the higher of the then  Dividend  Multiple or Vote
Multiple  applicable to the Preferred  Stock. In the case of property other than
securities, the "Fair Market Value" thereof shall be determined in good faith by
the Board of Directors of the Company  based upon such  appraisals  or valuation
reports of such  independent  experts as the Board of  Directors  of the Company
shall in good faith determine to be appropriate in accordance with good business
practices and the interests of the holders of Rights.  Any such determination of
Fair Market Value shall be described in a statement  filed with the Rights Agent
and shall be binding upon the Rights Agent.

     (c) All  calculations  under this  Section 11 shall be made to the  nearest
cent or to the nearest  one  one-hundredth  of a share,  as the case may be. 

     (d)  Irrespective  of any adjustment or change in the Exercise Price or the
number of shares of Preferred  Stock  issuable  upon the exercise of the Rights,
the Rights  Certificates  theretofore  and  thereafter  issued may  continue  to
express the Exercise  Price and 


<PAGE>

the number of shares to be issued upon  exercise of the Rights as in the initial
Rights  Certificates  issued  hereunder but,  nevertheless,  shall represent the
Rights as so adjusted.

     (e) Before  taking any action that would cause an  adjustment  reducing the
purchase  price per whole share of Preferred  Stock upon  exercise of the Rights
below the then par value, if any, of the shares of Preferred  Stock, the Company
shall use its best  efforts  to 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  non-assessable  shares of such Preferred  Stock at
such adjusted  purchase price per share.  

     (f)  Anything in this Section 11 to the  contrary  notwithstanding,  in the
event of any  reclassification of stock of the Company or any  recapitalization,
reorganization or partial liquidation of the Company or similar transaction, the
Company  shall be entitled  to make such  further  adjustments  in the number of
shares of Preferred Stock which may be acquired upon exercise of the Rights, and
such  adjustments  in  the  Exercise  Price  therefor,   in  addition  to  those
adjustments  expressly  required by the other  paragraphs of this Section 11, as
the Board of  Directors  of the  Company  shall  determine  to be  necessary  or
appropriate  in order for the  holders of the Rights in such event to be treated
equitably and in accordance with the purpose and intent of this Rights Agreement
or in order  that any such  event  shall not,  but for such  adjustment,  in the
opinion of counsel to the  Company,  result in the  stockholders  of the Company
being  subject to any United  States  federal  income  tax  liability  by reason
thereof.  

     (g) In the event the  Company  shall at any time after the Record Date make
any distribution on the shares of Common Stock of the Company, whether by way of
a dividend or a reclassification of stock, a recapitalization, reorganization or
partial  liquidation of the Company or otherwise,  in cash or any debt security,
debt instrument, real or personal 


<PAGE>

property or any other  property  (other than any shares of Common Stock or other
capital  stock of the Company and other than any right or warrant to acquire any
such shares,  including any debt security  convertible  into or exchangeable for
any such  share,  at less than the Fair  Market  Value of such  shares)  and the
amount of such cash  dividend  or the Fair Market  Value of such debt  security,
debt  instrument or property  exceeds 150% of the  aggregate  amount of the cash
dividends  declared or paid on the Common  Stock of the Company in the  15-month
period  immediately  preceding such  distribution,  then and in each such event,
unless such  distribution is part of or is made in connection with a transaction
to which  Section  11(a)(ii) or Section 13 hereof  applies,  the Exercise  Price
shall be reduced by an amount equal to the cash or the Fair Market Value of such
distribution,  as the case may be, per share of Common Stock of the Company. For
purposes  hereof,  the Fair  Market  Value of any  property  distributed  to the
holders of shares of Common Stock of the Company  shall be the Fair Market Value
of such property as determined by an investment  banking firm experienced in the
valuation of securities or the other  property so  distributed,  as the case may
be,  selected in good faith by the Board of Directors of the Company,  or, if no
such  investment  banking  firm is in the good  faith  judgment  of the Board of
Directors  available to make such  determination,  in good faith by the Board of
Directors of the Company,  whose determination shall be final and binding on the
Company, the Rights Agent and the holders of Rights.

     Section 12.  Certification of Adjusted  Exercise Price or Number of Shares.
Whenever an  adjustment  is made as  provided  in Section  11, 13 or 23(c),  the
Company shall (a) promptly prepare a certificate  setting forth such adjustment,
and a brief statement of the facts giving rise to such adjustment,  (b) promptly
file with the Rights Agent and with each transfer agent for the Preferred  Stock
a copy of such  certificate  and (c) mail a brief summary 

<PAGE>

thereof to each holder of a Rights  Certificate  in accordance  with Section 25.
Notwithstanding the foregoing sentence,  the failure of the Company to make such
certification  or give such notice shall not affect the validity of or the force
or effect of the  requirement  for such  adjustment.  Any  adjustment to be made
pursuant to Section 11, 13 or 23(c) of this Rights  Agreement shall be effective
as of the date of the event  giving rise to such  adjustment.  The Rights  Agent
shall  be  fully  protected  in  relying  on  any  such  certificate  and on any
adjustment  therein  contained and shall not be deemed to have  knowledge of any
adjustment unless and until it shall have received such certificate.

     Section 13. Consolidation,  Merger or Sale or Transfer of Assets or Earning
Power. 

     (a) In the event that,  at any time after the time that any Person  becomes
an Acquiring Person, (x) the Company shall, directly or indirectly,  consolidate
with, or merge with and into,  any other Person or Persons (other than an Exempt
Person) and the Company shall not be the surviving or continuing  corporation of
such consolidation or merger, or (y) any Person or Persons (other than an Exempt
Person) shall, directly or indirectly, consolidate with, or merge with and into,
the Company, and the Company shall be the continuing or surviving corporation of
such  consolidation  or merger and, in  connection  with such  consolidation  or
merger,  all or part of the outstanding  shares of Common Stock shall be changed
into or exchanged for stock or other  securities of any other Person (other than
an Exempt  Person) or of the Company or cash or any other  property,  or (z) the
Company or one or more of its Subsidiaries shall,  directly or indirectly,  sell
or otherwise  transfer to any other Person or any Affiliate or Associate of such
Person,  in one or  more  transactions,  or the  Company  or one or  more of its
Subsidiaries  shall sell or otherwise transfer to any Persons in one or a series
of 


<PAGE>

related  transactions,  assets or earning power aggregating more than 50% of the
assets or earning power of the Company and its Subsidiaries  (taken as a whole),
then, on the first occurrence of any such event,  proper provision shall be made
so that (i) each holder of record of a Right, except as provided in Section 7(e)
hereof,  shall  thereafter have the right to receive,  upon the exercise thereof
and payment of the Exercise  Price in  accordance  with the terms of this Rights
Agreement,  such number of shares of validly issued, fully paid,  non-assessable
and freely tradable Common Stock of the Principal Party (as defined herein), not
subject to any liens,  encumbrances,  rights of first  refusal or other  adverse
claims, as shall equal the result obtained by dividing the Exercise Price by 50%
of the Fair Market Value of the Common Stock of the Principal  Party on the date
of the consummation of such consolidation,  merger, sale or transfer;  (ii) such
Principal Party shall  thereafter be liable for, and shall assume,  by virtue of
such consolidation,  merger, sale or transfer, all the obligations and duties of
the Company pursuant to this Rights Agreement;  (iii) the term "Company" for all
purposes of this Rights  Agreement  shall  thereafter be deemed to refer to such
Principal Party; (iv) such Principal Party shall take such steps (including, but
not limited to, the  reservation of a sufficient  number of shares of its Common
Stock in accordance  with the  provisions of Section 9 hereof  applicable to the
reservation of Preferred  Stock) 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 its  shares of Common  Stock
thereafter deliverable upon the exercise of the Rights; provided, however, that,
upon the  subsequent  occurrence  of any merger,  consolidation,  sale of all or
substantially all of the assets,  recapitalization,  reclassification of shares,
reorganization or other  extraordinary  


<PAGE>

transaction  in respect of such  Principal  Party,  each holder of a Right shall
thereupon  be entitled to receive,  upon  exercise of a Right and payment of the
Exercise Price,  such cash,  shares,  rights,  warrants and other property which
such  holder  would have been  entitled  to receive  had it, at the time of such
transaction, owned the shares of Common Stock of the Principal Party purchasable
upon the  exercise of a Right,  and such  Principal  Party shall take such steps
(including,  but not  limited  to,  reservation  of  shares  of stock) as may be
necessary to permit the subsequent exercise of the Rights in accordance with the
terms hereof for such cash, shares, rights, warrants and other property; and (v)
the provisions of Section  11(a)(ii)  hereof shall be of no effect following the
occurrence  of any  event  described  in  clause  (x),  (y) or (z) above of this
Section 13(a).

     (b) "Principal Party" shall mean

         (i) in the case of any transaction described in (x) or (y) of the first
     sentence of Section 13(a) hereof:  (A) the Person that is the issuer of the
     securities  into which shares of Common Stock of the Company are changed or
     otherwise  exchanged or converted in such merger or  consolidation,  or, if
     there is more than one such issuer, the issuer of the Common Stock of which
     has the greatest  market value or (B) if no securities  are so issued,  (x)
     the Person that is the other party to the merger or consolidation  and that

<PAGE>


     consolidation,  or, if there is more than one such  Person,  the Person the
     Common  Stock of which has the  greatest  market value or (y) if the Person
     that is the other party to the merger or consolidation does not survive the
     merger or  consolidation,  the  Person  that  does  survive  the  merger or
     consolidation (including the Company if it survives); and

         (ii)  in the  case of any  transaction  described  in (z) of the  first
     sentence  in Section  13(a),  the Person  that is the party  receiving  the
     greatest  portion of the assets or earning  power  transferred  pursuant to
     such  transaction  or  transactions,  or, if each Person that is a party to
     such transaction or transactions receives the same portion of the assets or
     earning  power so  transferred  or if the  Person  receiving  the  greatest
     portion of the assets or earning power cannot be  determined,  whichever of
     such Persons as is the issuer of Common  Stock  having the greatest  market
     value of shares outstanding;  provided,  however, that in any such case, if
     the  Common  Stock  of such  Person  is not at such  time  and has not been
     continuously over the preceding 12-month period registered under Section 12
     of the Exchange Act, and such Person is a direct or indirect  Subsidiary of
     another Person the Common Stock of which is and has been so registered, the
     term "Principal  Party" shall refer to such other Person, or if such Person
     is a  Subsidiary,  directly or  indirectly,  of more than one  Person,  the
     Common  Stocks of all of which are and have  been so  registered,  the term
     "Principal Party" shall refer to whichever of such Persons is the issuer of
     the Common Stock having the  greatest  market value of shares  outstanding.

     (c) The Company shall not consummate any  consolidation,  merger or sale or
transfer  of assets or earning  power  referred to in Section  13(a)  unless the
Principal  Party  shall have a  sufficient  number of  authorized  shares of its
Common  Stock  that have not been  issued 


<PAGE>

or reserved for issuance to permit  exercise in full of all Rights in accordance
with this  Section 13 and unless  prior  thereto the  Company and the  Principal
Party involved  therein shall have executed and delivered to the Rights Agent an
agreement  confirming that the Principal Party shall,  upon consummation of such
consolidation,  merger or sale or  transfer of assets or earning  power,  assume
this Rights  Agreement  in  accordance  with  Section  13(a) hereof and that all
rights of first  refusal or  preemptive  rights in respect  of the  issuance  of
shares of Common  Stock of the  Principal  Party upon  exercise  of  outstanding
Rights have been waived and that such transaction  shall not result in a default
by the Principal Party under this Rights Agreement,  and further providing that,
as soon as practicable  after the date of any  consolidation,  merger or sale or
transfer of assets or earning power  referred to in Section  13(a)  hereof,  the
Principal Party will:

         (i)  prepare  and  file a  registration  statement  under  the Act with
     respect to the Rights and the securities  purchasable  upon exercise of the
     Rights  on an  appropriate  form,  use  its  best  efforts  to  cause  such
     registration  statement to become  effective as soon as  practicable  after
     such filing and use its best efforts to cause such  registration  statement
     to  remain   effective   (with  a  prospectus  at  all  times  meeting  the
     requirements  of the Act) until the date of expiration  of the Rights,  and
     similarly comply with applicable state securities laws;

         (ii) use its best  efforts to list (or  continue  the  listing  of) the
     Rights and the  securities  purchasable  upon  exercise  of the Rights on a
     national  

<PAGE>


     securities  exchange or to meet the eligibility  requirements for quotation
     on NASDAQ; and

         (iii) deliver to holders of the Rights historical  financial statements
     for the Principal Party which comply in all respects with the  requirements
     for registration on Form 10 (or any successor form) under the Exchange Act.
     In the event that any of the transactions described in Section 13(a) hereof
     shall occur at any time after the occurrence of a transaction  described in
     Section  11(a)(ii)  hereof,  the  Rights  which have not  theretofore  been
     exercised  shall,  subject  to  the  provisions  of  Section  7(e)  hereof,
     thereafter be exercisable in the manner  described in Section 13(a). 

     (d) In case the  Principal  Party  which is to be a party to a  transaction
referred  to in  this  Section  13 has a  provision  in  any  of its  authorized
securities or in its Certificate of Incorporation or By-laws or other instrument
governing its corporate  affairs,  which  provision would have the effect of (i)
causing such Principal Party to issue,  in connection  with, or as a consequence
of, the consummation of a transaction  referred to in this Section 13, shares of
Common Stock of such Principal Party at less than the then Fair Market Value per
share  (determined  pursuant to Section 11(b) hereof) or securities  exercisable
for, or convertible into, Common Stock of such Principal Party at less than such
then Fair Market Value (other than to holders of Rights pursuant to this Section
13) or (ii) providing for any special tax or similar  payment in connection with
the  issuance to any holder of a Right of Common Stock of such  Principal  Party
pursuant to the provisions of this Section 13, then, in such event,  the Company
shall not consummate any such  transaction  unless prior thereto the Company and
such  


<PAGE>

Principal  Party  shall  have  executed  and  delivered  to the  Rights  Agent a
supplemental  agreement  providing  that  the  provision  in  question  of  such
Principal  Party  shall  have  been  canceled,  waived or  amended,  or that the
authorized  securities shall be redeemed,  so that the applicable provision will
have no effect in connection  with, or as a consequence of, the  consummation of
the proposed transaction.

     Section 14. Fractional Rights and Fractional  Shares. 

     (a) The Company  shall not be required to issue  fractions  of Rights or to
distribute Rights Certificates which evidence fractional Rights (i.e., Rights to
acquire less than one one-hundredth of a share of Preferred Stock),  unless such
fractional  Rights  result from a  transaction  referred to in Section  11(a)(i)
hereof.  If the Company  shall  determine not to issue such  fractional  Rights,
then, in lieu of such fractional  Rights,  there shall be paid to the holders of
record of the Rights  Certificates  with regard to which such fractional  Rights
would otherwise be issuable, an amount in cash equal to the same fraction of the
Fair Market  Value of a whole  Right.  

     (b) The  Company  shall not be  required  to issue  fractions  of shares of
Preferred  Stock  (other  than  fractions   which  are  integral   multiples  of
one-hundredth  of a  share)  upon  exercise  of  the  Rights  or  to  distribute
certificates  which evidence  fractional  shares (other than fractions which are
integral multiples of one-hundredth of a share). In lieu of issuing fractions of
shares of Preferred  Stock,  the Company may, at its election,  issue depositary
receipts  evidencing  fractions of shares  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 of the rights, privileges and preferences to which they would be entitled as
owners of the Preferred  Stock.  With respect to fractional  


<PAGE>

shares that are not  integral  multiples  of  one-hundredth  of a share,  if the
Company does not issue such  fractional  shares or  depositary  receipts in lieu
thereof,  there shall be paid to the holders of record of Rights Certificates at
the time such Rights are exercised as herein provided an amount in cash equal to
the same fraction of the Fair Market Value of a share of Preferred Stock.

     (c) The holder of a Right by the acceptance of a Right expressly waives his
right to receive any  fractional  Right or any  fractional  shares of  Preferred
Stock (other than fractions which are integral multiples of one one-hundredth of
a share) upon exercise of a Right.  

     Section  15.  Rights of  Action.  All  rights of action in  respect of this
Rights  Agreement,  except  the rights of action  given to the  Rights  Agent in
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates  (and, prior to the Distribution Date, the holders of record of the
Common Stock);  and any holder of record of any Rights Certificate (or, prior to
the Distribution  Date, of the Common Stock),  without the consent of the Rights
Agent  or of the  holder  of any  other  Rights  Certificate  (or,  prior to the
Distribution Date, of the Common Stock),  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 Rights  Certificate in the manner provided
in such Rights  Certificate and, in this Rights 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  Rights  Agreement  and will be  entitled  to  specific
performance of the 

<PAGE>

obligations under, and injunctive relief against actual or threatened violations
of, the obligations of any Person subject to this Rights Agreement.

     Section  16.  Agreement  of Right  Holders.  Each  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 shall be evidenced by the
Book-Entries  representing,  or the certificates for, Common Stock registered in
the name of the  holders of Common  Stock  (together,  as  applicable,  with the
Summary of Rights), which Book-Entries representing, or certificates for, Common
Stock shall also constitute  certificates for Rights, and not by separate Rights
Certificates,  and each Right  shall be  transferable  only  simultaneously  and
together with the transfer of shares of Common Stock; 

     (b) After the Distribution  Date, the Rights  Certificates are transferable
only on the registry  books of the Rights Agent if  surrendered at the office of
the Rights Agent designated for such purpose,  duly endorsed or accompanied by a
proper instrument of transfer; 

     (c) The Company and the Rights Agent may deem and treat the person in whose
name the Rights  Certificate (or, prior to the Distribution Date, the associated
Book-Entry representing,  or certificate for, Common Stock) is registered as the
absolute owner thereof and of the Rights evidenced thereby  (notwithstanding any
notations of ownership or writing on the Rights  Certificates  or the associated
Common  Stock  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. 

     (d) Notwithstanding anything in this Agreement to the contrary, neither the
Company nor the Rights  Agent shall have any  liability to any holder of a Right
or a beneficial 


<PAGE>

interest in a Right or other Person as a result of its  inability to perform any
of its  obligations  under  this  Agreement  by  reason  of any  preliminary  or
permanent  injunction  or other  order,  decree or  ruling  issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency
or commission,  or any statute,  rule, regulation or executive order promulgated
or enacted by any governmental  authority,  prohibiting or otherwise restraining
performance of such obligation; provided, however, the Company must use its best
efforts to have any such order, decree or ruling lifted or otherwise  overturned
as soon as possible; and

     (e)  Rights  beneficially  owned by  certain  persons  will  under  certain
circumstances  set forth in this  Agreement  become  null and void  pursuant  to
Section 7(e) hereof;  and 

     (f)  This  Agreement  may be  supplemented  or  amended  from  time to time
pursuant to Section 26 hereof.  

     Section 17. Rights Certificate Holder Not Deemed a Stockholder.  No holder,
as such, of any Rights  Certificate shall be entitled to vote, receive dividends
or be  deemed  for any  purpose  the  holder  of  Preferred  Stock or any  other
securities  which may at any time be  issuable  on the  exercise  of the  Rights
represented  thereby,  nor shall  anything  contained  herein  or in any  Rights
Certificate be construed to confer upon the holder of any Rights 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  (except as provided  in Section  7(f)  hereof),  or to give or
withhold  consent to any  corporate  action  (except as provided in Section 7(f)
hereof),   or  to  receive  notice  of  meetings  or  other  actions   affecting
stockholders  (except as provided in Section 24 hereof), or to receive dividends
or subscription  


<PAGE>

rights,  or  otherwise,  until  the  Right or Rights  evidenced  by such  Rights
Certificate shall have been exercised in accordance with the provisions hereof.

     Section 18.  Concerning the Rights Agent.  

     (a) 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  Rights
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
to  be  done  by  the  Rights  Agent  in  connection  with  the  acceptance  and
administration  of this Rights  Agreement,  including  the cost and  expenses of
defending  against any claim of liability  relating to the Rights or this Rights
Agreement. 

     (b) The  Rights  Agent  shall be  protected  against,  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 Rights Agreement in reliance upon any
Rights Certificate or certificate for Preferred Stock 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. 

<PAGE>



     Section 19.  Merger or  Consolidation  of, or Change in Name of, the Rights
Agent.  

     (a) 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
corporate trust or stock transfer  business of the Rights Agent or any successor
Rights  Agent,  shall be the  successor  to the Rights  Agent  under this Rights
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 Rights  Agreement any of the Rights  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
Rights Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign  such  Rights  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  Rights  Certificates  shall  have the full  force  provided  in the Rights
Certificates and in this Rights  Agreement.  

     (b) 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 Rights  Certificates so  countersigned;  in case at that time any of
the Rights Certificates shall not have been countersigned,  the Rights Agent may
countersign such Rights  Certificates either in its 


<PAGE>

prior name or in its changed  name;  in all such cases such Rights  Certificates
shall have the full force provided in the Rights Certificates and in this Rights
Agreement.

     Section 20. Duties of Rights Agent.  The Rights Agent undertakes the duties
and  obligations  imposed by this Rights  Agreement upon the following terms and
conditions,  by all of which the Company and the holders of Rights  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
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 Rights  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 the Chairman of the Board, the President
or any Vice  President  and by the Treasurer or the Secretary of the Company and
delivered to the Rights Agent. Any 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 Rights Agreement in reliance upon such  certificate. 

     (c) The Rights Agent shall be liable hereunder 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 Rights  Agreement  or in the
Rights  Certificates  


<PAGE>

(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 Rights  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 Rights  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant  or  condition  contained  in this  Rights  Agreement  or in any Rights
Certificate;  nor shall it be responsible for any adjustment  required under the
provisions of Section 11 or 13 hereof or responsible  for the manner,  method or
amount of any such adjustment or the ascertaining of the existence of facts that
would require any such adjustment (except with respect to the exercise of Rights
evidenced by Rights  Certificates after receipt of a certificate  describing any
such  adjustment);  nor  shall it by any act  hereunder  be  deemed  to make any
representation  or warranty as to the authorization or reservation of any shares
of Preferred Stock to be issued pursuant to this Rights  Agreement or any Rights
Certificate or as to whether any shares of Preferred Stock 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 the  Rights  Agreement.  

     (g)  The  Rights  Agent  is  hereby   authorized  and  directed  to  accept
instructions  with respect to the  performance of its duties  hereunder from the
Chairman of the Board,  the President or any Vice  President or the Secretary or
the  Treasurer  of the  Company,  and to 


<PAGE>

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 to be taken by it in
good faith in accordance with instructions of any such officer.

     (h) The Rights Agent and any shareholder,  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 the Rights  Agent under
this Rights  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  Rights
Agreement  upon 30 days'  notice in writing  mailed to the  Company  and to each
transfer  agent of the Common Stock and the  Preferred  Stock by  registered  or
certified mail. The Company may remove the Rights Agent or any successor  Rights
Agent  (with or without  cause) 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 Stock and the  Preferred  Stock by  registered  or certified
mail. If the Rights Agent shall resign or be removed or shall  otherwise  become
incapable of acting,  


<PAGE>

the Company shall appoint a successor to the Rights Agent.  Notwithstanding  the
foregoing  provisions of this Section 21, in no event shall the  resignation  or
removal of a Rights Agent be effective until a successor Rights Agent shall have
been appointed and have accepted such appointment.  If the Company shall fail to
make such appointment  within a period of 30 days after 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 Rights  Certificate  (who
shall,  with such notice,  submit his Rights  Certificate  for inspection by the
Company),  then the incumbent Rights Agent or the holder of record of any Rights
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) a  corporation  organized  and  doing
business  under the laws of the United States or of any state  thereof,  in good
standing,  which is authorized  under such laws to exercise  corporate  trust or
stock  transfer  powers and is  subject to  supervision  or  examination  in the
conduct of its corporate  trust or stock  transfer  business by federal or state
authorities  and which  has at the time of its  appointment  as  Rights  Agent a
combined  capital  and  surplus  of at  least  $5,000,000  or (b)  an  Affiliate
controlled  by a  corporation  described in clause (a) of this  sentence.  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  


<PAGE>

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
Stock  and  Preferred  Stock,  and  mail a  notice  thereof  in  writing  to the
registered  holders  of the  Rights  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.
Notwithstanding the foregoing provisions,  in the event of resignation,  removal
or incapacity  of the Rights Agent,  the Company shall have the authority to act
as the Rights Agent until a successor Rights Agent shall have assumed the duties
of the Rights Agent hereunder.

     Section 22. Issuance of New Rights Certificates. Notwithstanding any of the
provisions  of this  Rights  Agreement  or of the  Rights to the  contrary,  the
Company may, at its option,  issue new Rights Certificates  evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change  in the  Exercise  Price per share and the  number or kind or class of
shares of stock or other  securities  or property  purchasable  under the Rights
Certificates  made in accordance  with the provisions of this Rights  Agreement.

     Section 23. Redemption. 

     (a) The Company  may, at its option,  but only by the vote of a majority of
the Board of Directors, redeem all but not less than all of the then outstanding
Rights,  at any time prior to the Close of  Business  on the  earlier of (i) the
tenth day  following  the Stock  Acquisition  Date  (subject to extension by the
Company as  provided  in Section 26 hereof) or (ii) the  Expiration  Date,  at a
redemption  price of $0.01 per Right,  subject to  adjustments  as  provided  in
subsection  (c)  below  (the  "Redemption  Price").   Notwithstanding   anything
contained in this Agreement to the contrary, the Rights shall not be exercisable
pursuant to Section  11(a)(ii) prior to the expiration of the Company's right of
redemption hereunder. 


<PAGE>


     (b)  Without  any  further  action and  without  any  notice,  the right to
exercise the Rights will terminate effective at the time so designated by action
of the Board of  Directors  ordering the  redemption  of the Rights and the only
right  thereafter  of the holders of Rights  shall be to receive the  Redemption
Price.  Within 10 days  after the  effective  time of the action of the Board of
Directors  ordering the redemption of the Rights,  the Company shall give notice
of such redemption to the holders of the then outstanding Rights by mailing such
notice to all such  holders  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 Stock.  Any notice which is
mailed in the manner herein  provided shall be deemed given,  whether or not the
holder  receives the notice.  Each notice of redemption will state the method by
which the  payment of the  Redemption  Price will be made.  At the option of the
Board of  Directors,  the  Redemption  Price may be paid in cash to each  Rights
holder or by the issuance of shares (and, at the Company's  election pursuant to
Section 14(b) hereof, cash or depositary receipts in lieu of fractions of shares
other than fractions which are integral  multiples of one one-hundredth  (1/100)
of a share) of Preferred  Stock or Common Stock having a Fair Market Value equal
to such cash  payment.  

     (c) In the  event  the  Company  shall at any time  after  the date of this
Rights Agreement (A) pay any dividend on Common Stock in shares of Common Stock,
(B)  subdivide  or split the  outstanding  shares of Common Stock into a greater
number of shares or (C) combine or consolidate the outstanding  shares of Common
Stock  into a  smaller  number  of  shares  or  effect  a  reverse  split of the
outstanding   shares  of  Common  Stock,  or  (D)  combine  or  consolidate  the
outstanding  shares  of  Common  Stock  into a  smaller  number of shares of its
capital  stock in a  reclassification  of the Common Stock  (including  any such
reclassification  in  


<PAGE>

connection with a consolidation or merger in which the Company is the continuing
or surviving  corporation),  then, and in each such event,  the Redemption Price
shall be appropriately adjusted to reflect the foregoing.

     Section 24. Notice of Proposed Actions. 

     (a) In case the Company,  after the Distribution Date, shall propose (i) to
effect any of the transactions  referred to in Section 11(a)(i) or 11(g) or (ii)
to offer to the  holders of record of its Common  Stock  options,  warrants,  or
other rights to subscribe for or to purchase  shares of Common Stock  (including
any security  convertible  into or  exchangeable  for Common Stock) or shares of
stock of any class or any other securities,  options,  warrants,  convertible or
exchangeable securities or other rights, or (iii) to effect any reclassification
of its Preferred Stock or Common Stock or any recapitalization or reorganization
of the Company,  or (iv) to effect any  consolidation or merger with or into, 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  more  than  50% of the  assets  or  earning  power  of the  Company  and its
Subsidiaries  (taken as a whole)  to,  any other  Person or  Persons,  or (v) to
effect the liquidation,  dissolution or winding up of the Company, then, in each
such  case,  the  Company  shall  give to each  holder  of  record  of a  Rights
Certificate,  in accordance  with Section 25,  notice of such  proposed  action,
which  shall  specify  the  record  date for the  purposes  of such  transaction
referred to in Section 11(a)(i) or such dividend or distribution, or the date on
which such reclassification,  recapitalization,  reorganization,  consolidation,
merger, sale or transfer of assets,  liquidation,  dissolution, or winding up is
to take place and the record date for determining  participation  therein by the
holders of record of Common Stock or Preferred  Stock, if any such date is to be
fixed,  and such notice  shall be so given in the case of any 


<PAGE>

action  covered by clause (i) or (ii) above at least 10 days prior to the record
date for  determining  holders of record of the Preferred  Stock 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 record of Common Stock or Preferred  Stock,  whichever
shall be the earlier.  The failure to give notice required by this Section 24 or
any defect therein shall not affect the legality or validity of the action taken
by the Company or the vote upon any such action.

     (b) In case any of the transactions referred to in Section 11(a)(i),  11(g)
or 13 of this Rights Agreement are proposed, then, in any such case, the Company
shall  give to each  holder of Rights,  in  accordance  with  Section 25 hereof,
notice  of  the  proposal  of  such  transaction  at  least  10  days  prior  to
consummating such transaction, which notice shall specify the proposed event and
the consequences of the event to holders of Rights under Section 11(a)(i), 11(g)
or 13 hereof, as the case may be, and, upon consummating such transaction, shall
similarly give notice thereof to each holder of Rights.

this  Rights  Agreement  to be given or made by the  Company or by the holder of
record of any Rights  Certificate  or Right to or on the Rights  Agent  shall be

                     Re:  Moore Medical Corp.

Notices or demands  authorized  by this Rights  Agreement to be given or made by
the  Company  or the  Rights  Agent  to  the  holder  of  record  of any  Rights
Certificate or Right shall be sufficiently  given or made if sent by first-class
mail, postage prepaid, addressed to such holder at the address of such holder as
shown on the registry books of the Company.

     Section 26. Supplements and Amendments.  For as long as the Rights are then
redeemable  and except as provided in the last  sentence of this Section 26, the
Company may in its sole and absolute  discretion,  and the Rights Agent shall if
the Company so directs,  supplement  or amend any  provision  of this  Agreement
without the  approval of any holders of the Rights.  At any time when the Rights
are not then  redeemable,  the Company  may,  and the Rights  Agent shall if the
Company so  directs,  supplement  or amend this  Rights  Agreement  without  the
approval of any holders of Rights  Certificates (i) to cure any ambiguity,  (ii)
to correct or supplement any provision  contained  herein which may be defective
or  inconsistent  with  any  other  provisions  herein  or (iii)  to  change  or
supplement  the  provisions  hereunder  in 


<PAGE>

any manner which the Company may deem  necessary or desirable,  provided that no
such  supplement  or amendment  pursuant to this clause  (iii) shall  materially
adversely  affect the interest of the holders of Rights  Certificates.  Upon the
delivery of a  certificate  from an  appropriate  officer of the  Company  which
states that the proposed supplement or amendment is in compliance with the terms
of this Section 26, the Rights Agent shall execute such supplement or amendment.
Notwithstanding  anything contained in this Rights Agreement to the contrary, no
supplement or amendment shall be made which changes the Redemption  Price or the
Expiration  Date and  supplements  or amendments may be made after the time that
any Person becomes an Acquiring  Person only if at the time of the action of the
Board of Directors  approving  such  supplement  or amendment  there are then in
office not less than two Continuing  Directors and such  supplement or amendment
is approved by a majority of the Continuing Directors then in office.

     Section 27. 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 7(e) hereof)
for  shares  of  Common  Stock at an  exchange  ratio of one  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 an  Exempt  Person),  together  with  all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Voting Stock then outstanding.


<PAGE>



     (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 27
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 shares of Common  Stock 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 shares of Common  Stock 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 7(e) hereof) held by each holder of Rights.

     (c) In the event that there shall not be sufficient  shares of Common Stock
issued but not  outstanding or authorized but unissued to permit any exchange of
Rights as contemplated in accordance with this Section 27, the Company shall use
its best efforts to cause additional shares of Common Stock to be authorized for
issuance upon exchange of the Rights.

     (d) The  Company  shall not be  required  to issue  fractions  of shares of
Common Stock or to distribute  certificates which evidence fractional shares. In
lieu of such 


<PAGE>

fractional shares, the Company shall pay to the registered holders of the Rights
Certificates  with regard to which such fractional  shares of Common Stock would
otherwise  be  issuable  an amount  in cash  equal to the same  fraction  of the
current market value of a whole share of Common Stock.  For the purposes of this
paragraph  (d), the current  market value of a whole share of Common Stock shall
be the closing price of a share of Common Stock for the Trading Day  immediately
prior to the date of exchange pursuant to this Section 27.

     Section 28. Successors.  All of the covenants and provisions of this Rights
Agreement  by or for the benefit of the  Company or the Rights  Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

     Section  29.  Benefits  of this  Rights  Agreement.  Nothing in this Rights
Agreement shall be construed to give to any person or corporation other than the
Company,  the Rights Agent and the registered holders of the Rights Certificates
(and,  prior to the  Distribution  Date,  the  holders of Common  Stock in their
capacity as holders of the Rights) any legal or equitable right, remedy or claim
under this Rights Agreement; but this Rights Agreement shall be for the sole and
exclusive benefit of the Company,  the Rights Agent and the holders of record of
the Rights  Certificates  (and, prior to the  Distribution  Date, the holders of
Common Stock in their capacity as holders of the Rights).

     Section  30.  Delaware  Contract.  This  Rights  Agreement  and each Rights
Certificate  issued  hereunder  shall be deemed to be a contract  made under the
laws of the State of  Delaware  and for all  purposes  shall be  governed by and
construed and enforced in accordance  with the laws of such state  applicable to
contracts to be made and performed entirely within such state.



<PAGE>


     Section  31.  Counterparts.  This Rights  Agreement  may be executed in any
number of counterparts and each of such  counterparts  shall for all purposes be
deemed to be an original,  and all such counterparts  shall together  constitute
but one and the same instrument.

     Section  32.  Descriptive  Headings.  Descriptive  headings  of the several
Sections of this Rights  Agreement are inserted for  convenience  only and shall
not  control or affect  the  meaning or  construction  of any of the  provisions
hereof.

     Section 33. Severability.  If any term, provision,  covenant or restriction
of this Rights  Agreement is held by a court of competent  jurisdiction or other
authority  to be invalid,  void or  unenforceable,  the  remainder of the terms,
provisions,  covenants and restrictions of this rights agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

     IN WITNESS WHEREOF, the parties hereto have caused this Rights Agreement to
be duly executed, all as of the day and year first above written.

                   THE RIGHTS AGREEMENT (AS REFERREDTO BELOW),
                   RIGHTS ISSUED TO OR BENEFICIALLY OWNED BY

                 OF SUCH RIGHTS SHALL BE NULL AND VOID AND MAY

                               MOORE MEDICAL CORP.

                          SUMMARY OF RIGHTS TO PURCHASE
                         SERIES I JUNIOR PREFERRED STOCK


     On November 18, 1998,  the Board of Directors of MOORE MEDICAL  CORP.  (the
"Company")  declared a dividend  distribution  of one preferred  stock  purchase
right for each outstanding share of Common Stock, par value $0.01 per share (the
"Common Stock"), of the Company held by stockholders of record on March 17, 1999
(the "Record Date").  Each Right entitles the registered holder to purchase from
the  Company  one  one-hundredth  (1/100) of a share of  preferred  stock of the
Company,  designated as Series I Junior Preferred Stock (the " Preferred Stock")
at a price  of $70 per  one  one-hundredth  (1/100)  of a share  (the  "Exercise
Price").  The  description  and  terms of the  Rights  are set forth in a Rights
Agreement (the "Rights  Agreement"),  dated as of November 18, 1998, between the
Company and  American  Stock  Transfer & Trust Co., as Rights Agent (the "Rights
Agent").

     AS  DISCUSSED  BELOW,   INITIALLY  THE  RIGHTS  WILL  NOT  BE  EXERCISABLE,
CERTIFICATES WILL NOT BE SENT TO STOCKHOLDERS AND THE RIGHTS WILL  AUTOMATICALLY
TRADE WITH THE COMMON STOCK.



<PAGE>


     The  Rights,  unless  earlier  redeemed by the Board of  Directors,  become
exercisable  upon the close of  business  on the day (the  "Distribution  Date")
which is the earlier of (i) the tenth day  following  the first date (the "Stock
Acquisition  Date")  on which  there is a public  announcement  that a person or
group of affiliated or associated  persons,  with certain  exceptions  set forth
below,  has  acquired  beneficial  ownership  of 15% or more of the  outstanding
voting  stock of the Company (an  "Acquiring  Person") or such  earlier or later
date (not  beyond the  thirtieth  day after the Stock  Acquisition  Date) as the
Board of Directors may determine and (ii) the tenth  business day (or such later
date as may be  determined  by the Board of Directors  prior to such time as any
person or group of affiliated or associated persons becomes an Acquiring Person)
after the date of the  commencement  or  announcement  of a person's  or group's
intention to commence a tender or exchange offer the consummation of which would
result in the ownership of 15% or more of the Company's outstanding voting stock
(even if no  shares  are  actually  purchased  pursuant  to such  offer);  prior
thereto,  the  Rights  will not be  exercisable,  will not be  represented  by a
separate certificate,  and will not be transferable apart from the Common Stock,
but will instead be  evidenced,  (i) with respect to any of the shares of Common
Stock held in uncertificated  book-entry form (a "Book-Entry") outstanding as of
the  Record  Date,  by such  Book-Entry  and (ii) with  respect to the shares of
Common Stock evidenced by Common Stock certificates outstanding as of the Record
Date, by such Common Stock certificate,  together with a copy of this Summary of
Rights. An Acquiring Person does not include (A) the Company, (B) any subsidiary
of the  Company,  (C) any employee  benefit  plan or employee  stock plan of the
Company  or of any  subsidiary  of the  Company,  or any  trust or other  entity
organized, appointed, established or holding 


<PAGE>

Common  Stock for or pursuant to the terms of any such plan or (D) any person or
group  whose  ownership  of 15% or more of the  shares  of  voting  stock of the
Company then  outstanding  results  solely from (i) any action or transaction or
transactions  approved  by the Board of  Directors  before  such person or group
became an  Acquiring  Person or (ii) a  reduction  in the number of  outstanding
shares of voting stock of the Company  pursuant to a transaction or transactions
approved by the Board of Directors  (provided that any person or group that does
not  become an  Acquiring  Person by reason of clause  (i) or (ii)  above  shall
become an Acquiring  Person upon  acquisition of an additional 1% or more of the
Company's voting stock unless such  acquisition of additional  voting stock will
not result in such  person or group  becoming an  Acquiring  Person by reason of
such clause (i) or (ii)).  For  purposes of the  foregoing,  outstanding  voting
stock of the Company  includes voting stock that trades on a "when issued" basis
on a national securities  exchange or on the National  Association of Securities
Dealers, Inc. Automated Quotation System ("NASDAQ").

     Until the  Distribution  Date (or earlier  redemption  or expiration of the
Rights),  new Common Stock certificates issued after March 17, 1999 will contain
a legend incorporating the Rights Agreement by reference. Until the Distribution
Date (or  earlier  redemption  or  expiration  of the  Rights),  transfer on the
Company's  Direct  Registration  System of any  Common  Stock  represented  by a
Book-Entry or a certificate outstanding as of March 17, 1999, and, in each case,
with or without a copy of this  Summary of Rights  attached  thereto,  will also
constitute  the  transfer  of  the  Rights  associated  with  the  Common  Stock
represented by such Book-Entry or certificate.  As soon as practicable following
the  Distribution  Date,  separate  certificates  evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the 


<PAGE>

Distribution Date and such separate Rights  Certificates alone will evidence the
Rights from and after the Distribution Date.

     The Rights are not exercisable until the Distribution  Date. Unless earlier
redeemed by the Company as described  below, the Rights will expire at the close
of business on March 17, 2009 (the  "Expiration  Date") (or, if the Distribution
Date shall have occurred  before March 17, 2009, at the close of business on the
90th day following the Distribution Date).

     The Preferred  Stock is  nonredeemable  and, unless  otherwise  provided in
connection  with  the  creation  of a  subsequent  series  of  preferred  stock,
subordinate to any other series of the Company's  preferred stock. The Preferred
Stock may not be issued except upon exercise of Rights.  Each share of Preferred
Stock will be entitled to receive when, as and if declared, a quarterly dividend
in an amount equal to (i) 100 times the cash dividends declared on the Company's
Common Stock,  and (ii) a preferential  cash dividend,  if any, in preference to
holders of Common Stock in an amount equal to $1.00 per share of Preferred Stock
less the per share amount of all cash dividends  declared on the Preferred Stock
pursuant  to clause  (i)  since the  immediately  preceding  quarterly  dividend
payment date. In addition, Preferred Stock is entitled to 100 times any non-cash
dividends (other than dividends  payable in equity  securities)  declared on the
Common Stock, in like kind. In the event of the liquidation of the Company,  the
holders  of  Preferred  Stock will be  entitled  to  receive,  for each share of
Preferred  Stock,  a payment  in an amount  equal to the  greater of $70 per one
one-hundredth share plus accrued and unpaid dividends and distributions  thereon
or 100 times the payment made per share of Common Stock. Each share of Preferred
Stock will have 100 votes,  voting  together with the Common Stock. In the event
of any merger,  consolidation  or other  transaction  in which  Common  Stock is
exchanged,  each share of Preferred  Stock will be entitled to receive 100 times
the amount received per share of Common Stock.  The rights of Preferred Stock as
to dividends,  liquidation and voting are protected by anti-dilution provisions.
If the  dividends  accrued  on the  Preferred  Stock for four or more  quarterly
dividend periods,  whether  consecutive or not, shall not have been declared and
paid or  irrevocably  set  aside  for  payment,  the  holders  of  record of the
Preferred  Stock of the Company of all series  (including  the Preferred  Stock)
will have the right to elect two members to the Company's Board of Directors.

     The number of shares of  Preferred  Stock  issuable  upon  exercise  of the
Rights is  subject to  certain  adjustments  from time to time in the event of a
stock  dividend on, or a subdivision or  combination  of, the Common Stock.  The
Exercise  Price  for the  Rights  is  subject  to  adjustment  in the  event  of
extraordinary  distributions  of cash or other  property  to  holders  of Common
Stock.

     Unless the Rights are earlier  redeemed,  in the event that, after the time
that a Person becomes an Acquiring Person,  the Company were to be acquired in a
merger or other  business  combination  (in which any shares of Common Stock are
changed into or exchanged  for other  securities  or assets) or more than 50% of
the assets or earning  power of the  Company  and its  subsidiaries  (taken as a
whole)  were  to  be  sold  or  transferred  in  one  or  a  series  of  related
transactions,  the Rights Agreement  provides that proper provision will be made
so that each holder of record,  other than the Acquiring Person, of a Right will
from and after such date have the right to receive, upon payment of the Exercise
Price,  that number of shares of common stock of the acquiring  company as shall
equal the result  obtained by dividing the  Exercise  Price by 50% of the market
value of the common stock of the acquiring company.

     In addition,  unless the Rights are earlier  redeemed,  in the event that a
person or group becomes an Acquiring Person,  the Rights Agreement provides that
proper  provision  will be made so that each holder of record of a Right,  other
than the Acquiring  Person (whose Rights will  thereupon  become null and void),
will thereafter  have the right to receive,  upon payment of the Exercise Price,
that number of one  one-hundredths  of a share of Preferred Stock as shall equal
the result obtained by dividing the Exercise Price by 50% of the market value of
the Preferred  Stock (such market value to be determined  with  reference to the
market value of the Company's Common Stock as provided in the Rights Agreement).

     At any time after any person or group becomes an Acquiring Person and prior
to the  acquisition  by such  person or group of 50% or more of the  outstanding
voting  stock,  the Board of  Directors  of the Company may  exchange the Rights
(other than Rights  owned by such person or group which will have become  void),
in whole or in part, at an exchange ratio of one share of Common Stock per Right
(subject to adjustment).

     Fractions of shares of  Preferred  Stock  (other than  fractions  which are
integral  multiples of one one-hundredth of a share) may, at the election of the
Company, be evidenced by depositary receipts. The Company may also issue cash in
lieu of fractional shares which are not integral  multiples of one one-hundredth
of a share.

     At any time on or prior to the close of  business on the earlier of (i) the
tenth day after the Stock  Acquisition Date (or such later date as a majority of
the Board of Directors may determine) or (ii) the  Expiration  Date, the Company
may redeem the Rights in whole,  but not in part,  at a price of $0.01 per Right
(the "Redemption  Price").  Immediately upon the effective time of the action of
the Board of Directors of the Company authorizing  redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price.

     For as long as the Rights are then redeemable, the Company may, except with
respect to the redemption  price or date of expiration of the Rights,  amend the
Rights in any manner,  including an amendment to extend the time period in which
the Rights may be redeemed. At any time when the Rights are not then redeemable,
the  Company  may  amend  the  Rights in any  manner  that  does not  materially
adversely  affect the interests of holders of the Rights as such.  Amendments to
the  Rights  Agreement  from and  after  the time  that any  Person  becomes  an
Acquiring  Person and amendments to the redemption  price or expiration  date of
the Rights  require the approval of a majority of the  Continuing  Directors (as
defined and provided in the Rights Agreement).

     Until a Right is exercised,  the holder,  as such, will have no rights as a
stockholder of the Company, including,  without limitation, the right to vote or
to receive dividends.

     A copy of the  Rights  Agreement  has been filed  with the  Securities  and
Exchange  Commission  as an  Exhibit to the  Company's  report on Form 8-K dated
December [ ], 1998. A copy of the Rights  Agreement is available  free of charge
from the Company.  This summary description of the Rights does not purport to be
complete and is  qualified in its entirety by reference to the Rights  Agreement
which is incorporated in this summary description herein by reference.

Preferred  Stock") of the  Company at a purchase  price of $70,  as the same may
from time to time be  adjusted  in  accordance  with the Rights  Agreement  (the
"Exercise  Price"),  upon presentation and surrender of this Rights  Certificate
with the Form of Election to Purchase attached hereto duly executed.

     As provided in the Rights  Agreement,  the Exercise Price and the number of
shares of Preferred Stock which may be purchased upon the exercise of the Rights
evidenced by this Rights  Certificate are subject to modification and adjustment
upon the happening of certain events and, upon the happening of certain  events,
securities  other than shares of  Preferred  Stock,  or other  property,  may be
acquired upon exercise of the Rights  evidenced by this Rights  Certificate,  as
provided in the Rights Agreement.

     This  Rights  Certificate  is subject to all of the terms,  provisions  and
conditions of the Rights Agreement,  which terms,  provisions and conditions are
incorporated  herein by  reference  and made a part  hereof and to which  Rights
Agreement  reference  is  hereby  made  for a full  description  of the  rights,

for such purpose,  may be exchanged  for another  Rights  Certificate  or Rights
Certificates  of like tenor and date evidencing  Rights  entitling the holder of
record to purchase a like aggregate  number of shares of Preferred  Stock as the
Rights evidenced by the Rights  Certificate or Rights  Certificates  surrendered
shall have entitled such holder to purchase. If this Rights Certificate 


<PAGE>

shall be  exercised  in part,  the holder  shall be  entitled  to  receive  upon
surrender  hereof,  another Rights  Certificate or Rights  Certificates  for the
number of whole Rights not exercised.

     Subject to the provisions of the Rights Agreement,  the Rights evidenced by
this  Certificate  may be redeemed by the Company at its option or under certain
other  circumstances  at a redemption  price of $0.01 per Right.  No  fractional
shares of Preferred Stock (other than fractions which are integral  multiples of
one  one-hundredth  (1/100)  of a share)  are  required  to be  issued  upon the
exercise  of any Right or  Rights  evidenced  hereby,  and in lieu  thereof  the
Company may cause depositary  receipts to be issued and/or a cash payment may be
made, as provided in the Rights Agreement.

     No holder of this Rights Certificate, as such, shall be entitled to vote or
receive  dividends or be deemed for any purpose the holder of Preferred Stock or
of any other  securities of the Company which may at any time be issuable on the
exercise hereof,  nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder  hereof,  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 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  the  Rights
Agreement), or to receive dividends or subscription rights, or otherwise,  until
the  Right or  Rights  evidenced  by this  Rights  Certificate  shall  have been
exercised as provided in the Rights Agreement. This Rights Certificate shall not
be valid or obligatory for any purpose until it shall have been countersigned by
the Rights Agent.

                         SERIES I JUNIOR PREFERRED STOCK

                               MOORE MEDICAL CORP.

                     Pursuant to Section 151 of the Delaware
                             General Corporation Law

     I, [name],  [title] of Moore Medical  Corp.,  a  corporation  organized and
existing  under  the  Delaware  General  Corporation  Law  (the  "Company"),  in
accordance  with the  provisions  of Section 151 of such law, DO HEREBY  CERTIFY
that: 

     1. No shares of the  Company's  Series I Junior  Preferred  Stock have been
issued. 

     2. The original  Certificate of Designations  of Series I Junior  Preferred
Stock of Moore Medical  Corp.  was filed with the Secretary of State of Delaware
on March 17, 1989 (the "Original  Certificate of Designations").  

     3. Pursuant to the authority  conferred  upon the Board of Directors by the
Certificate of  Incorporation  of the Company and pursuant to Section 151 of the
Delaware  General  Corporation  Law the Board of  Directors on November 18, 1998
adopted the  following  resolution  which  amends the  Original  Certificate  of
Designations, as follows:

     RESOLVED,  that pursuant to the authority  vested in the Board of Directors
of  the  Company  in  accordance  with  the  provisions  of its  Certificate  of
Incorporation,  a series of  Preferred  Stock of the  Company be, and hereby is,
created  and that the  designation  and amount  thereof  and the voting  powers,
preferences and relative, participating, optional or other special 


<PAGE>

rights of the shares of such  series,  and the  qualifications,  limitations  or
restrictions thereof are as follows:

     Section  1.  Designation  and Amount.  The shares of such series  shall be
designated as "Series I Junior Preferred Stock" (the "Series I Preferred Stock")
and the number of shares  constituting  such  series  shall be  70,000.  

     Section 2.   Dividends and Distributions. 

     (A) Subject to the  provisions for adjustment  hereinafter  set forth,  the
holders of shares of Series I  Preferred  Stock  shall be  entitled  to receive,
when,  as and if  declared  by the  Board  of  Directors  out of  funds  legally
available for the purpose, (i) cash dividends in an amount per share (rounded to
the nearest  cent) equal to 100 times the aggregate per share amount of all cash
dividends  declared or paid on the Common Stock,  $0.01 par value per share,  of
the Company (the "Common  Stock") and (ii) a  preferential  cash  dividend  (the
"Preferential Dividends"), if any, on the first day of February, May, August and
November of each year (each 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 I  Preferred  Stock,  in an amount  (except in the
case of the  first  Quarterly  Dividend  Payment  Date if the date of the  first
issuance of Series I Preferred  Stock is a date other than a Quarterly  Dividend
Payment  Date,  in which case such  payment  shall be a prorated  amount of such
amount) equal to $1.00 per share of Series I Preferred  Stock less the per share
amount of all cash dividends  declared on the Series I Preferred  Stock pursuant
to  clause  (i) of this  sentence  since  the  immediately  preceding  Quarterly
Dividend  Payment Date or, with respect to the first Quarterly  Dividend Payment
Date,  since the first  issuance of any share or fraction of a share of Series I
Preferred  Stock. In the event the Company shall, at any time after the issuance
of any  


<PAGE>

share or fraction of a share of Series I Preferred Stock,  make any distribution
on the shares of Common Stock of the Company,  whether by way of a dividend or a
reclassification  of  stock,  a  recapitalization,   reorganization  or  partial
liquidation  of the Company or  otherwise,  which is payable in cash or any debt
security,  debt  instrument,  real or personal  property  or any other  property
(other than cash dividends  subject to the  immediately  preceding  sentence,  a
distribution  of shares of Common Stock or other capital stock of the Company or
a  distribution  of rights or warrants to acquire any such share,  including any
debt security  convertible  into or exchangeable  for any such share, at a price
less than the Fair Market Value (as hereinafter  defined) of such share),  then,
and in each  such  event  the  Company  shall  simultaneously  pay on each  then
outstanding share of Series I Preferred Stock of the Company a distribution,  in
like  kind,  of 100 times  such  distribution  paid on a share of  Common  Stock
(subject to the provisions for adjustment  hereinafter set forth). The dividends
and  distributions  on the Series I Preferred Stock to which holders thereof are
entitled  pursuant  to clause (i) of the first  sentence of this  paragraph  and
pursuant to the second sentence of this paragraph are hereinafter referred to as
"Participating  Dividends" and the multiple of such cash and non-cash  dividends
on the  Common  Stock  applicable  to  the  determination  of the  Participating
Dividends,  which shall be 100 initially but shall be adjusted from time to time
as hereinafter  provided, is hereinafter referred to as the "Dividend Multiple".
In the event the Company shall at any time after March 17, 1999 (the  "Effective
Date")  declare or pay any  dividend or make any  distribution  on Common  Stock
payable  in shares  of  Common  Stock,  or  effect a  subdivision  or split or a
combination,  consolidation or reverse split of the outstanding shares of Common
Stock into a greater or lesser number of shares of Common Stock, or issue any of
its capital stock in a 


<PAGE>

reclassification  of the Common Stock  (including any such  reclassification  in
connection with a consolidation or merger in which the Company is the continuing
or  surviving  corporation),  then in  each  such  case  the  Dividend  Multiple
thereafter  applicable  to the  determination  of the  amount  of  Participating
Dividends  which holders of shares of Series I Preferred Stock shall be entitled
to receive shall be the Dividend Multiple  applicable  immediately prior to such
event multiplied 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 Company shall declare each Participating  Dividend at the same time
it declares any cash or non-cash dividend or distribution on the Common Stock in
respect of which a  Participating  Dividend is  required to be paid.  No cash or
non-cash  dividend  or  distribution  on the Common  Stock in respect of which a
Participating  Dividend  is  required  to be paid shall be paid or set aside for
payment on the Common Stock unless a  Participating  Dividend in respect of such
dividend or  distribution on the Common Stock shall be  simultaneously  paid, or
set aside  for  payment,  on the  Series I  Preferred  Stock.  

     (C) Preferential  Dividends shall begin to accrue on outstanding  shares of
Series I Preferred Stock from the Quarterly Dividend Payment Date next preceding
the date of  issuance  of any shares of Series I  Preferred  Stock.  Accrued but
unpaid  Preferential  Dividends  shall  cumulate  but shall  not bear  interest.
Preferential  Dividends  paid on the  shares of Series I  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.  


<PAGE>



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

     (A) Subject to the provisions for adjustment  hereinafter  set forth,  each
share of Series I Preferred  Stock shall entitle the holder thereof to 100 votes
on all matters  submitted  to a vote of the  stockholders  of the  Company.  The
number of votes which a holder of Series I Preferred  Stock is entitled to cast,
as the  same may be  adjusted  from  time to time as  hereinafter  provided,  is
hereinafter  referred to as the "Vote Multiple".  In the event the Company shall
at any time after the Effective Date declare or pay any dividend on Common Stock
payable  in shares  of  Common  Stock,  or  effect a  subdivision  or split or a
combination,  consolidation or reverse split of the outstanding shares of Common
Stock into a greater or lesser number of shares of Common Stock, or issue any of
its capital stock in a reclassification  of the Common Stock (including any such
reclassification  in  connection  with a  consolidation  or  merger in which the
Company is the continuing or surviving  corporation,  then in each such case the
Vote Multiple thereafter  applicable to the determination of the number of votes
per  share to which  holders  of shares of  Series I  Preferred  Stock  shall be
entitled after such event shall be the Vote Multiple  immediately  prior to such
event multiplied 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  the   Certificate  of
Incorporation or By-laws,  the holders of shares of Series I Preferred Stock and
the holders of shares of Common  Stock  shall vote  together as one class on all
matters  submitted to a vote of  stockholders  of the Company.  



<PAGE>


     (C) In the event that the  Preferential  Dividends  accrued on the Series I
Preferred Stock for four or more quarterly dividend periods, whether consecutive
or not,  shall not have been  declared  and paid or set apart for  payment,  the
holders of record of Preferred Stock of the Company of all series (including the
Series I Preferred Stock),  other than any series in respect of which such right
is expressly  withheld by the  Certificate of  Incorporation  or the authorizing
resolutions included in the Certificate of Designations therefor, shall have the
right, at the next meeting of stockholders called for the election of directors,
to elect two  members to the Board of  Directors,  which  directors  shall be in
addition to the number  required by the  By-laws  prior to such event,  to serve
until the next  Annual  Meeting  and until  their  successors  are  elected  and
qualified or their  earlier  resignation,  removal or  incapacity  or until such
earlier  time  as  all  accrued  and  unpaid  Preferential  Dividends  upon  the
outstanding  shares  of  Series I  Preferred  Stock  shall  have  been  paid (or
irrevocably  set aside for  payment) in full.  The holders of shares of Series I
Preferred  Stock shall continue to have the right to elect directors as provided
by the immediately  preceding sentence until all accrued and unpaid Preferential
Dividends  upon the  outstanding  shares of Series I Preferred  Stock shall have
been paid (or set aside for payment) in full.  Such directors may be removed and
replaced by such stockholders, and vacancies in such directorships may be filled
only  by  such  stockholders  (or by the  remaining  director  elected  by  such
stockholders,  if  there  be  one) in the  manner  permitted  by law;  provided,
however,  that any such  action by  stockholders  shall be taken at a meeting of
stockholders  and shall not be taken by written consent  thereto.  

     (D) Except as otherwise  required by the  Certificate of  incorporation  or
By-laws or set forth herein,  holders of Series I Preferred  Stock shall have no
special  voting rights 


<PAGE>

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 the taking of any
corporate action.

     Section 4.  Certain  Restrictions.  

     (A) Whenever  Preferential  Dividends  or  Participating  Dividends  are in
arrears or the Company shall be in default of payment  thereof,  thereafter  and
until all accrued and unpaid Preferential Dividends and Participating Dividends,
whether or not declared, on shares of Series I Preferred Stock outstanding shall
have been paid or set aside for payment in full,  and in addition to any and all
other rights which any holder of shares of Series I Preferred  Stock may have in
such circumstances, the Company shall not

         (i) declare or pay  dividends on, make any other  distributions  on, or
     redeem or purchase or otherwise  acquire for  consideration,  any shares of
     stock  ranking  junior  (either  as  to  dividends  or  upon   liquidation,
     dissolution or winding up) to the Series I Preferred Stock;

         (ii) declare or pay dividends on or make any other distributions on any
     shares of stock  ranking  on a parity  as to  dividends  with the  Series I
     Preferred  Stock,  unless  dividends  are  paid  ratably  on the  Series  I
     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 if the full dividends accrued thereon were to
     be paid;

         (iii) except as permitted by subparagraph  (iv) of this paragraph 4(A),
     redeem or purchase or  otherwise  acquire for  consideration  shares of any
     stock  ranking on a parity  (either as to  dividends  or upon  liquidation,
     dissolution or winding up) with the 


<PAGE>

     Series I Preferred Stock, provided that the Company may at any time redeem,
     purchase or otherwise  acquire  shares of any such parity stock in exchange
     for shares of any stock of the Company ranking junior (both as to dividends
     and upon liquidation,  dissolution or winding up) to the Series I Preferred
     Stock; or

         (iv)  purchase or  otherwise  acquire for  consideration  any shares of
     Series I Preferred  Stock,  or any shares of stock ranking on a parity with
     the Series I Preferred  Stock (either as to dividends or upon  liquidation,
     dissolution or winding up), except in accordance with a purchase offer made
     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 Company shall not permit any Subsidiary (as hereinafter defined) of
the Company to purchase or  otherwise  acquire for  consideration  any shares of
stock of the  Company  unless the Company  could,  under  paragraph  (A) of this
Section 4,  purchase or  otherwise  acquire such shares at such time and in such
manner. A "Subsidiary" of the Company shall mean any corporation or other entity
of which  securities or other ownership  interests  having ordinary voting power
sufficient  to elect a  majority  of the  board of  directors  or other  persons
performing similar functions are beneficially owned, directly or indirectly,  by
the Company or by any  corporation or other entity that is otherwise  controlled
by the Company.

     (C) The  Company  shall not issue any  shares of Series I  Preferred  Stock
except upon  exercise of Rights issued  pursuant to either the Rights  Agreement
dated as of 


<PAGE>

November 18, 1998 between the Company and American Stock Transfer & Trust Co. or
the Rights  Agreement dated as of March 8, 1989 between the Company and American
Stock Transfer and Trust Co.,  copies of which are on file with the Secretary of
the Company at its  principal  executive  office and shall be made  available to
stockholders of record without charge upon written request therefor addressed to
said Secretary. Notwithstanding the foregoing sentence, nothing contained in the
provisions  hereof  shall  prohibit or restrict the Company from issuing for any
purpose any series of  Preferred  Stock with rights and  privileges  similar to,
different from, or greater than, those of the Series I Preferred Stock.

     Section  5.   Reacquired  Shares.  Any shares of Series I  Preferred  Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and canceled  promptly after the  acquisition  thereof.  All such shares
upon their  retirement  and  cancellation  shall become  authorized but unissued
shares of Preferred Stock, without designation as to series, and such shares may
be  reissued  as part of a new  series  of  Preferred  Stock  to be  created  by
resolution or resolutions of the Board of Directors.

     Section 6.   Liquidation,  Dissolution or Winding Up. Upon any voluntary or
involuntary   liquidation,   dissolution  or  winding  up  of  the  Company,  no
distribution  shall be made (i) to the holders of shares of stock ranking junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series I  Preferred  Stock  unless the  holders of shares of Series I  Preferred
Stock shall have received,  subject to adjustment as hereinafter  provided,  (A)
$70 per one-hundredth share plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment,
or (B) if greater than the amount  specified in clause (i)(A) of this  sentence,
an amount equal to 100 times the aggregate amount to be distributed per share to
holders of Common Stock,  as the

same may be adjusted as hereinafter  provided,  and (ii) to the holders of stock
ranking on a parity upon liquidation,  dissolution or winding up with the Series
I  Preferred  Stock,  unless  simultaneously  therewith  distributions  are made
ratably  on the Series I  Preferred  Stock and all other  shares of such  parity
stock in  proportion  to the total  amounts  to which the  holders  of shares of
Series I Preferred  Stock are entitled  under clause (i)(A) of this sentence and
to which the holders of such parity shares are entitled,  in each case upon such
liquidation,  dissolution or winding up. The amount to which holders of Series I
Preferred Stock may be entitled upon  liquidation,  dissolution or winding up of
the Company  pursuant to clause (i)(B) of the foregoing  sentence is hereinafter
referred to as the  "Participating  Liquidation  Amount" and the multiple of the
amount  to be  distributed  to  holders  of  shares  of  Common  Stock  upon the
liquidation,  dissolution  or winding up of the Company  applicable  pursuant to
said clause to the  determination of the  Participating  Liquidation  Amount, as
said  multiple may be adjusted  from time to time as  hereinafter  provided,  is
hereinafter referred to as the "Liquidation Multiple". In this event the Company
shall at any time after the Effective Date declare or pay any dividend on Common
Stock payable in shares of Common Stock,  or effect a subdivision  or split or a
combination,  consolidation or reverse split of the outstanding shares of Common
Stock into a greater or lesser number of shares of Common Stock, or issue any of
its capital stock in a reclassification  of the Common Stock (including any such
reclassification  in  connection  with a  consolidation  or  merger in which the
Company is the continuing or surviving  corporation,  then in each such case the
Liquidation   Multiple  thereafter   applicable  to  the  determination  of  the
Participating  Liquidation  Amount to which holders of Series I Preferred  Stock
shall be entitled after such event shall be the Liquidation  Multiple applicable
immediately

prior to such event  multiplied  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.   Certain Reclassifications and Other Events.

     (A) In the event  that  holders  of shares of Common  Stock of the  Company
receive after the Effective Date, in respect of their shares of Common Stock any
share of capital  stock of the Company  (other than any share of Common Stock of
the   Company),   whether   by   way  of   reclassification,   recapitalization,
reorganization,  dividend or other  distribution or otherwise (a "Transaction"),
then, and in each such event the dividend rights,  voting rights and rights upon
the  liquidation,  dissolution  or  winding  up of the  Company of the shares of
Series I Preferred  Stock shall be adjusted so that after such event the holders
of Series I  Preferred  Stock  shall be  entitled,  in  respect of each share of
Series I Preferred  stock held, in addition to such rights in respect thereof to
which such holder was entitled immediately prior to such adjustment, to (i) such
additional  dividends as equal the Dividend Multiple in effect immediately prior
to such Transaction multiplied by the additional dividends which the holder of a
share of Common  Stock  shall be entitled to receive by virtue of the receipt in
the  Transaction of such capital stock,  (ii) such  additional  voting rights as
equal  the  Vote  Multiple  in  effect  immediately  prior  to such  Transaction
multiplied by the additional voting rights which the holder of a share of Common
Stock shall be  entitled to receive by virtue of the receipt in the  Transaction
of such capital stock and (iii) such additional  distributions upon liquidation,
dissolution  or winding up of the Company as equal the  Liquidation  Multiple in
effect immediately prior to such Transaction multiplied by the additional amount
which the holder of a share of Common  Stock shall be  entitled to receive  


<PAGE>

upon  liquidation,  dissolution  or winding  up of the  Company by virtue of the
receipt in the  Transaction  of such capital  stock,  as the case may be, all as
provided by the terms of such capital stock.

     (B) In the event  that  holders  of shares of Common  Stock of the  Company
receive after the Effective Date, in respect of their shares of Common Stock any
right or warrant to purchase  Common Stock  (including as such a right,  for all
purposes of this paragraph,  any security  convertible  into or exchangeable for
Common Stock) at a purchase  price per share less than the Fair Market Value (as
hereinafter  defined) of a share of Common Stock on the date of issuance of such
right or warrant, then and in each such event the dividend rights, voting rights
and rights upon the liquidation, dissolution or winding up of the Company of the
shares of Series I  Preferred  Stock  shall each be  adjusted so that after such
event the Dividend  Multiple,  the Vote  Multiple and the  Liquidation  Multiple
shall each be the product of the Dividend  Multiple,  the Vote  Multiple and the
Liquidation  Multiple,  as the case may be, in effect  immediately prior to such
event  multiplied  by a fraction  the  numerator of which shall be the number of
shares of Common Stock outstanding immediately before such issuance of rights or
warrants  plus the  maximum  number of shares of  Common  Stock  which  could be
acquired  upon  exercise  in  full  of all  such  rights  or  warrants  and  the
denominator  of which shall be the number of shares of Common Stock  outstanding
immediately before such issuance of rights or warrants plus the number of shares
of Common Stock which could be purchased, at the Fair Market Value of the Common
Stock at the  time of such  issuance,  by the  maximum  aggregate  consideration
payable upon exercise in full of all such rights or warrants.

     (C) In the event  that  holders  of shares of Common  Stock of the  Company
receive after the Effective  Date in respect of their shares of Common Stock any
right or 


<PAGE>

warrant to purchase  capital  stock of the Company  (other than shares of Common
Stock),  including  as such a right,  for all  purposes of this  paragraph,  any
security  convertible  into or  exchangeable  for capital  stock of the Company,
(other  than  Common  Stock),  at a purchase  price per share less than the Fair
Market  Value of such  shares of capital  stock on the date of  issuance of such
right or warrant, then and in each such event the dividend rights, voting rights
and rights  upon  liquidation,  dissolution  or winding up of the Company of the
shares of Series I  Preferred  Stock  shall each be  adjusted so that after such
event each holder of a share of Series I Preferred  Stock shall be entitled,  in
respect of each share of Series I  Preferred  Stock  held,  in  addition to such
rights in respect thereof to which such holder was entitled immediately prior to
such  event,  to receive (i) such  additional  dividends  as equal the  Dividend
Multiple in effect  immediately  prior to such event  multiplied,  first, by the
additional  dividends  to which the holder of a share of Common  Stock  shall be
entitled  upon  exercise of such right or warrant by virtue of the capital 


<PAGE>

stock which could be acquired  upon such  exercise and  multiplied  again by the
Discount  Fraction  (as  hereinafter  defined) and (ii) such  additional  voting
rights as equal the Vote  Multiple  in effect  immediately  prior to such  event
multiplied,  first,  by the  additional  voting  rights to which the holder of a
share of Common Stock shall be entitled  upon  exercise of such right or warrant
by virtue of the capital  stock which could be acquired  upon such  exercise and
multiplied again by the Discount Fraction and (iii) such additional distribution
upon  liquidation,  dissolution  or  winding  up of the  Company  as  equal  the
Liquidation  Multiple  in effect  immediately  prior to such  event  multiplied,
first,  by the  additional  amount  which the holder of a share of Common  Stock
shall be entitled to receive upon liquidation,  dissolution or winding up of the
Company  upon  exercise of such right or warrant by virtue of the capital  stock
which could be acquired upon such exercise and multiplied  again by the Discount
Fraction.  For purposes of this  paragraph,  the "Discount  Fraction" shall be a
fraction the numerator of which shall be the difference  between the Fair Market
Value of a share of the capital stock subject to a right or warrant  distributed
to holders of shares of Common  Stock of the  Company  as  contemplated  by this
paragraph  immediately after the distribution thereof and the purchase price per
share for such share of capital stock  pursuant to such right or warrant and the
denominator  of which shall be the Fair Market  Value of a share of such capital
stock immediately after the distribution of such right or warrant.

     (D) For  purposes of this  Certificate  of  Designations,  the "Fair Market
Value" of a share of capital  stock of the Company  (including a share of Common
Stock) on any date shall be deemed to be the average of the daily  closing price
per  share  thereof  over the 30  consecutive  Trading  Days  (as  such  term is
hereinafter defined) immediately prior to such date; provided, however, that, in
the event that such Fair  Market  Value of any such  share of  capital  stock is
determined  during a period  which  includes  any date that is within 30 Trading
Days after (i) the  ex-dividend  date for a dividend  or  distribution  on stock
payable in shares of such stock or  securities  convertible  into shares of such
stock,  or (ii)  the  effective  date of any  subdivision,  split,  combination,
consolidation,  reverse stock split or reclassification of such stock, then, and
in each such case, the Fair Market Value shall be appropriately  adjusted by the
Board  of  Directors  of  the  Company  to  take  into  account  ex-dividend  or
post-effective  date  trading.  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  applicable  transaction  reporting  system  with  respect  to
securities listed or admitted to trading on the New York Stock Exchange), or, if
the shares are 


<PAGE>

not listed or admitted to trading on the New York Stock Exchange, as reported in
the applicable transaction reporting system with respect to securities listed on
the  principal  national  securities  exchange on which the shares are listed or
admitted  to trading  or, if the shares are 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
Quotation System  ("NASDAQ") or such other system then in use, or if on any such
date the  shares  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 shares  selected by the Board of Directors  of the Company.  The
term "Trading Day" shall mean a day in which the principal  national  securities
exchange  on which the shares are listed or  admitted to trading is open for the
transaction  of business or, if the shares are not listed or admitted to trading
on any national  securities  exchange,  on which the New York Stock  Exchange or
such other  national  securities  exchange  as may be  selected  by the Board of
Directors of the Company is open.  If the shares are not publicly held or not so
listed or traded on any day within the period of 30 Trading Days  applicable  to
the determination of Fair Market Value thereof as aforesaid, "Fair Market Value"
shall mean the fair market value  thereof per share as  determined in good faith
by the Board of  Directors  of the  Company.  In either case  referred to in the
foregoing sentence, the determination of Fair Market Value shall be described in
a statement filed with the Secretary of the Company.

     Section  8.   Consolidation,  Merger,  etc. In case the Company 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
outstanding  share  of  Series I  Preferred  Stock  shall  at the  same  time be
similarly  exchanged  for  or  changed  into  the  aggregate  amount  of  stock,
securities,  cash and/or other 


<PAGE>

property  (payable  in like  kind),  as the case may be, for which or into which
each share of Common Stock is changed or exchanged  multiplied by the highest of
the Vote Multiple,  the Dividend Multiple or the Liquidation  Multiple in effect
immediately prior to such event.

     Section 9.   Effective Time of Adjustments.

     (A)  Adjustments to the Series I Preferred Stock required by the provisions
hereof  shall be  effective  as of the time at which  the event  requiring  such
adjustments occurs.

     (B) The Company shall give prompt  written notice to each holder of a share
of Series I  Preferred  Stock of the  effect  of any  adjustment  to the  voting
rights, dividend rights or rights upon liquidation, dissolution or winding up of
the Company of such shares  required by the provisions  hereof.  Notwithstanding
the foregoing sentence, the failure of the Company to give such notice shall not
affect the  validity  of or the force or effect of or the  requirement  for such
adjustment.

     Section  10.  No  Redemption.  The shares of Series I Preferred Stock shall
not be  redeemable  at  the  option  of  the  Company  or  any  holder  thereof.
Notwithstanding the foregoing sentence of this Section,  the Company may acquire
shares of Series I Preferred  Stock in any other  manner  permitted  by law, the
provisions hereof and the Certificate of Incorporation of the Company.

     Section  11.  Ranking.  Unless  otherwise  provided in the  Certificate  of
Incorporation  of the Company or a  Certificate  of  Designations  relating to a
subsequent  series of  preferred  stock of the  Company,  the Series I Preferred
Stock shall rank junior to all other 


<PAGE>

series of the Company's  preferred  stock as to the payment of dividends and the
distribution of assets on  liquidation,  dissolution or winding up and senior to
the Common Stock.

     Section  12.  Amendment.  The  provisions  hereof  and the  Certificate  of
Incorporation  of the  Company  shall not be amended in any manner  which  would
adversely  affect the  rights,  privileges  or powers of the Series I  Preferred
Stock without,  in addition to any other vote of  stockholders  required by law,
the  affirmative  vote of the holders of two-thirds  or more of the  outstanding
shares of Series I Preferred Stock, voting together as a single class.

     Section  13.  Fractional  Shares. Series I Preferred Stock may be issued in
fractions  of a share (in one  one-hundredths  (1/100)  of a share and  integral
multiples thereof) that shall entitle the holder thereof,  in proportion to such
holder's  fractional  shares,  to exercise  voting  rights,  receive  dividends,
participate in distributions and have the benefit of all other rights of holders
of shares of Series I Preferred Stock.

     IN WITNESS  WHEREOF,  I have executed and  subscribed  this  Certificate to
Designations  and do affirm the foregoing as true under the penalties of perjury
this ___ day of December, 1998.
