Item 1.  Description of Securities to be Registered.
         ------------------------------------------

                  On June 10, 1998, the Board of Directors of the
Company declared a dividend of one Preferred Stock Purchase Right (the
"Right(s)") for each outstanding share of Common Stock, par value $0.10 per
share (the "Common Stock"), of the Company. The dividend is payable as of June
22, 1998 to stockholders of record on that date. Each Right entitles the
registered holder to purchase from the Company one one-hundredth (1/100) of a
share of a new series of preferred shares of the Company, designated as Series A
Junior Preferred Stock ("Preferred Stock"), at a price of $150.00 per one
one-hundredth (1/100) of a share (the "Exercise Price"), subject to certain
adjustments. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and American Stock
Transfer & Trust Co., as Rights Agent ("Rights Agent"), dated as of June 18,
1998.

                  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 a public announcement
that a



                                        2
<PAGE>

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") 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 would not be exercisable,
would not be represented by a separate certificate, and would not be
transferable apart from the Company's Common Stock, but will instead be
evidenced, with respect to any of the Common Stock certificates outstanding as
of June 22, 1998, by such Common Stock certificate with a copy of this Summary
of Rights attached thereto. 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 voting stock
for or



                                        3
<PAGE>

pursuant to the terms of any such plan, (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 issued and 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% 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)) or (E)
any person who, as of June 22, 1998, together with all affiliates and associates
of such person, was the beneficial owner of 15% or more of the voting stock of
the Company outstanding as of such date; provided, however, that any person
described in this clause (E) shall no longer be an exempt person and shall
become an Acquiring Person if (i) such person, together with all affiliates and
associates of such person, after June 22, 1998, acquires beneficial ownership of
an additional 1% or more of the voting stock



                                        4
<PAGE>

(unless such acquisition is pursuant to a transaction described in clause (D)(i)
or (D)(ii) above) or (ii) such person, together with all affiliates and
associates of such person, after June 22, 1998, reduces its beneficial ownership
of the voting stock to less than 15% of the outstanding voting stock and
thereafter acquires beneficial ownership of 15% or more of the outstanding
voting stock (unless such acquisition is pursuant to a transaction described in
clause (D)(1) or (D)(ii) above).

                  Until the Distribution Date (or earlier redemption or
expiration of the Rights), new Common Stock certificates issued after June 22,
1998 will contain a legend incorporating the Rights Agreement by reference.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
the surrender for transfer of any of the Company's Common Stock certificates
outstanding as of June 22, 1998 with or without a copy of the Summary of Rights
attached, will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate. As soon as practicable following
the Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Company's Common Stock
as of the close of business on the Distribution Date and such separate



                                        5
<PAGE>

certificates alone will evidence the Rights from and after the Distribution 
Date.

                  The Rights are not exercisable until the Distribution Date.
The Rights will expire at the close of business on June 10, 2008, unless earlier
redeemed by the Company as described below.

                  The Preferred Stock is non-redeemable 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 the greater of $0.10 per share and 100
times the cash dividends declared on the Company's Common Stock. In addition,
the 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 liquidation, the holders of Preferred Stock will be
entitled to receive for each share, a liquidation payment in an amount equal to
the greater of $1,500.00 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



                                        6
<PAGE>

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.

                  The number of shares of Preferred Stock issuable upon exercise
of the Rights and the Exercise Price for the Rights are 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 also 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 the
Company's 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



                                        7
<PAGE>

holder of record 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 having a market value at the time of such
transaction equal to two times the Exercise Price. In addition, unless the
Rights are earlier redeemed, if a person 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 would thereupon
become null and void), will thereafter have the right to receive, upon payment
of the Exercise Price, that number of shares of the Company's Preferred Stock
having a market value at the time of the transaction equal to two times the
Exercise Price (such market value to be determined with reference to the market
value of the Company's Common Stock as provided in the Rights Agreement). The
Rights Agreement also grants the Board of Directors the option, after any person
or group acquires beneficial ownership of 15% or more of the voting stock but
before there has been a 50% acquisition, to exchange one share of common stock
for each then valid right (which would exclude rights held by the Acquiring
Person that have become void).



                                        8
<PAGE>

                  Fractions of shares of Preferred Stock (other than fractions
that are integral multiples of one one-hundredth (1/100) 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 (1/100) of a share.

                  At any time on or prior to the close of business on the tenth
day after the time that a person has become an Acquiring Person, the Company may
redeem the Rights in whole, but not in part, at a price of $.01 per Right
("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
the 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.



                                        9
<PAGE>

                  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 June 17, 1998, there were 18,175,716 shares of Common
Stock issued and outstanding, 3,610,398 treasury shares issued (and 3,928,239
shares reserved for issuance under stock plans). 277,500 shares of Preferred
Stock have been reserved for issuance upon exercise of the Rights.

                  The Rights have certain anti-takeover effects. The Rights will
cause substantial dilution to a person or group who attempts to acquire the
Company on terms not approved by the Company's Board of Directors. The Rights
should not interfere with any merger or other business combination approved by
the Board since they may be redeemed by the Company at $.01 per Right at any
time until the close of business on the tenth day after a person or group has
obtained beneficial ownership of 15% or more of the voting stock.

                                    AGREEMENT

                  Agreement, dated as of June 18, 1998, by and between NAC Re
Corp., a Delaware corporation (the "Company"), and American Stock Transfer &
Trust Co., a banking corporation organized under the laws of the State of New
York (the "Rights Agent").

                              W I T N E S S E T H :

                  WHEREAS, on June 10, 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, $0.10 par value per share, of
the Company outstanding as of the close of business on June 22, 1998 (the
"Record Date"), each such Right representing the right to purchase one
one-hundredth of a share of Series A Junior Preferred Stock of the Company
("Preferred Stock") having the rights and preferences set forth in the form of
Certificate of Designations attached hereto as Exhibit C authorized by the Board
of Directors on June 10, 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, the Expiration Date or the Final
Expiration Date (as such terms are hereinafter defined);


<PAGE>


                  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:

                           (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, shall be the Beneficial Owner (as such term is
                  hereinafter defined) of 15% or more of the Voting Stock 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 who or which, together
                  with all Affiliates and Associates of such Person, would be an
                  Acquiring Person solely by reason of (A) being the Beneficial
                  Owner of shares of Voting Stock of the Company, the Beneficial
                  Ownership of which was acquired by such Person (together with
                  all Affiliates and Associates of such Person) pursuant to any
                  action or transaction or series of related actions or
                  transactions approved by the Board of Directors before such
                  Person (together with all Affiliates and Associates of such
                  Person) otherwise became an Acquiring Person or (B) a
                  reduction in the number of issued and outstanding shares of
                  Voting Stock



                                        2
<PAGE>

                  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 (together with all Affiliates and
                  Associates of such Person) thereafter acquires Beneficial
                  Ownership of an additional 1% of the Voting Stock of the
                  Company, 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 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 Agreement.

transfer of any certificate for Common Stock shall constitute the surrender for
transfer of the Right or Rights associated with the Common Stock evidenced
thereby, whether or not accompanied by a copy of the Summary of Rights.

                  (c) Rights shall be issued in respect of all shares of Common
Stock that become outstanding after the Record Date but prior to the earlier of
the Distribution Date, the Expiration Date or the Final Expiration Date.
Certificates for Common Stock (including, without limitation, certificates
issued upon original issuance, disposition from the Company's treasury or
transfer or exchange of Common Stock) after the Record Date but prior to the
earliest of the Distribution Date, the Expiration Date, or the Final Expiration
Date shall have impressed, printed, written or stamped thereon or otherwise
affixed thereto the following legend:

                  This certificate also evidences and entitles the holder hereof
         to the same number of Rights (subject to adjustment) as the number of
         shares of Common Stock represented by this certificate, such Rights
         being on the terms provided under the Rights Agreement between NAC Re
         Corp. and American Stock Transfer & Trust Co. (the "Rights Agent"),
         dated as of June 18, 1998, as it may be amended from time to time (the
         "Agreement"), the terms of which are incorporated herein by reference
         and a copy of which is on file at the principal executive offices of
         NAC Re Corp. Under certain circumstances, as set forth in the
         Agreement, such Rights shall be evidenced by separate certificates and
         shall no longer be evidenced by this certificate. NAC Re Corp. shall



                                       14
<PAGE>
         mail to the registered holder of this certificate a copy of the
         Agreement without charge within five days after receipt of a written
         request therefor. As provided in Section 7(e) of the Agreement, Rights
         issued to or Beneficially Owned by Acquiring Persons or their
         Affiliates or Associates (as such terms are defined in the Agreement)
         or any subsequent holder of such Rights shall be null and void and may
         not be exercised by or transferred to any Person.

                  (d) As soon as practicable after the Distribution Date, the
Company will prepare and execute, the Rights Agent will countersign, and the
Company will send or cause to be sent (and the Rights Agent will, if requested,
send), by first-class mail, postage prepaid, to each record holder of the Common
Stock as 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 "Right 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 Right Certificates and may be transferred by the transfer
of the Right Certificate as permitted hereby, separately and apart from any
transfer of one or more shares of Common Stock.

                  Section 4. Form of Right Certificates. The Right 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



                                       15
<PAGE>

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 Agreement. Subject to the
provisions of Section 22 hereof, Right 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 thereon 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").

                  Section 5.  Countersignature and Registration.

                  (a) Each Right 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 Right 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



                                       16

<PAGE>

the Company who shall have signed any Right 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 Right 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 Right
Certificates had not ceased to be such officer of the Company. Any Right
Certificate may be signed on behalf of the Company by any person who, on the
date of the execution of such Right Certificate, shall be a proper officer of
the Company to sign such Right Certificate, although at the date of the
execution of this Agreement any such person was not such an officer.

                  (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 surrender of Right Certificates upon
exercise or transfer, and in such other locations as may be required by law,
books for registration and transfer of the Right Certificates issued hereunder.
Such books shall show the names and addresses of the respective holders of the
Right Certificates, the number of Rights evidenced on its face by each of the
Right Certificates and the date of each of the Right Certificates.

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

                  (a) Subject to the provisions of Section 7(e), 7(f) and 14
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the earlier of the Expiration Date or the
Final Expiration Date, any Right Certificate, may be (i) transferred or (ii)
split up, combined or exchanged for one or more other Right Certificates,
entitling the registered holder to purchase a like number of shares of Preferred
Stock as the Right Certificate or Rights Certificates surrendered then entitled
such holder to purchase. Any registered holder desiring to transfer any Right
Certificate shall surrender the Right Certificate at the office of the Rights
Agent designated for the surrender of Right Certificates with the form of
certificate and assignment on the reverse side thereof duly endorsed (or enclose
with such Right 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 Right Certificate shall make such request in writing
delivered to the Rights Agent, and shall surrender the Right Certificate to be
split up, combined or exchanged at the office of the Rights Agent designated
therefor. Thereupon, the Rights Agent shall countersign and deliver to the
person entitled



                                       18
<PAGE>

thereto a Right Certificate or Right 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 Right Certificates.

                  (b) Subject to the provisions of Section 7(e), 7(f) and 14
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 Right
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 Right Certificate if mutilated, the Company shall cause a new Right
Certificate of like tenor to be issued and delivered to the registered owner in
lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

                  (a) The Rights shall not be exercisable until, and shall
become exercisable on, the Distribution Date (unless otherwise provided herein,
including, without limitation, the restrictions on exercisability set forth in
Section 7(e), 23(a) and 27(b) hereof). Except as otherwise provided herein, the
Rights may be exercised, in whole or in part, at any time commencing with the
Distribution Date upon surrender of the Right Certificate, with



                                       19
<PAGE>

the form of election to purchase and certificate on the reverse side thereof
duly executed (with signatures duly guaranteed), to the Rights Agent at the
principal office of the Rights Agent in New York, New York, together with
payment of the Exercise Price for each Right exercised, subject to adjustment as
hereinafter provided, at or prior to the Close of Business on the earlier of (i)
June 10, 2008 (the "Final Expiration Date") or (ii) the date on which the Rights
are redeemed as provided in Section 23 hereof or the date on which the Rights
are exchanged as provided in Section 27 hereof (such earlier date being herein
referred to as the "Expiration Date").

                  (b) The Exercise Price shall initially be $150.00 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
Right Certificate representing exercisable Rights with the form of election to
purchase and certificate 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



                                       20
<PAGE>

of the Right Certificate in accordance with Section 9(e) hereof, the Rights
Agent shall thereupon promptly (i) requisition from any transfer agent 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 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 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 (other than fractions that are
integral multiples of one one-hundredth of a share) 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 Right 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 Right 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



                                       21
<PAGE>

of Preferred Stock upon exercise of a Right for a reasonable period, not in
excess of 90 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(d)
hereof.

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

                  (e) Notwithstanding any provision of this Agreement to the
contrary, from and after the time (the "invalidation time") when any Person
first becomes an Acquiring 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 (or any such Associate or
Affiliate) to holders of its equity securities or to any Person with whom it has
any



                                       22
<PAGE>

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 such Persons
referred to in clause (y) and (z) above, shall be null and 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 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 Right Certificates or any other Person as a result of its failure to make any
determination with respect to an Acquiring Person or its Affiliates, Associates
or transferees hereunder. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person or any Affiliate or Associate thereof whose Rights would be null and void
pursuant to the provisions of this Section 7(e); no Right Certificate shall be
issued at any time upon the transfer of any Rights to an Acquiring Person (or an
Affiliate or Associate of such Acquiring Person) whose Rights would be null and
void pursuant to the provisions of this Section 7(e) or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate; and any Right Certificate delivered to the Rights Agent for transfer
to an Acquiring Person (or an Associate or Affiliate of



                                       23
<PAGE>

such Acquiring Person) whose Rights would be void pursuant to the provisions of
this Section 7(e) shall be cancelled.

                  (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 Right 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 as the Company shall reasonably request.

                  Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Agreement. The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall cancel
and retire, any Right Certificate purchased or acquired by the Company otherwise
than upon the exercise thereof. The Rights Agent shall deliver all cancelled
Right Certificates to the Company, or shall, at the



                                       24
<PAGE>

written request of the Company, destroy such cancelled Right 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.

                  (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 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 in the National Association of Securities Dealers'
Automated Quotation System 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



                                       25
<PAGE>

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 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 earlier of the
Expiration Date and the Final Expiration Date. The Company may temporarily
suspend, for a period of time not to exceed ninety 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



                                       26
<PAGE>

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 issuance or delivery of the Right 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 Right 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
Right Certificate, and the Company shall not be required to issue or deliver a
Right 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 holder of such Right 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 Right Certificate evidencing such Rights
was duly surrendered and payment of the Exercise Price (and any



                                       27
<PAGE>

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.

                  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 are subject to adjustment from time to time
as provided in this Section 11.

                           (a) (i) In the event the Company shall at any time
                  after the date of this Agreement (A) declare 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 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 one
                  one-hundredths of a share 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 one one-hundredths of a
                  share of Preferred Stock issuable immediately prior to such
                  event multiplied by a fraction, the numerator of



                                       28
<PAGE>

                  which is the number of shares of Common Stock outstanding
                  immediately prior to such event and the denominator of which
                  is the number of shares of Common Stock outstanding
                  immediately after such event and the Exercise Price to be in
                  effect after the record date for such event (if one shall have
                  been established or, if not, after the date of such event)
                  shall be determined by multiplying the Exercise Price in
                  effect immediately prior to such event 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 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 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
                           Agreement and payment of the Exercise Price, such
                           number of one one-hundredths of a share of Preferred
                           Stock as shall equal the result obtained by (1)
                           multiplying the then



                                       29
<PAGE>

                           current Exercise Price by the number of one
                           one-hundredths of a share of Preferred Stock for
                           which a Right is then exercisable and dividing the
                           product by (2) 50% of the per share Fair Market Value
                           of the Preferred Stock (determined pursuant to
                           Section 11(b) hereof) on the date of such occurrence.

                                        (iii) In the event that the Company does
                           not have available sufficient authorized but unissued
                           Preferred Stock to permit the exercise in full of the
                           Rights in accordance with the foregoing subparagraph
                           (ii), the Company shall take all such action as may
                           be necessary to authorize 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 the foregoing subparagraph (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,
                           or



                                       30
<PAGE>

                           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 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



                                       31
<PAGE>

ex-dividend date for a dividend or distribution on such stock payable in shares
of Common Stock or securities convertible into 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 posteffective 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 the National Association of Securities Dealers, Inc. Automated Quotation
System ("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



                                       32
<PAGE>

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 independent investment
banking firm experienced in the valuation of securities 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; 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 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



                                       33
<PAGE>

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) In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of Common Stock entitling
them (for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Common Stock or securities convertible into Common
Stock at a price per share (or having a conversion price per share, if a
security convertible into Common Stock) less than the then current per share
Fair Market Value of the Common Stock on such record date, the Exercise Price to
be in effect after such record date shall be determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
on such record date plus the number of shares of Common Stock which the
aggregate offering price of the total number of shares of Common Stock so to be
offered (and/or the aggregate initial conversion price of the convertible
securities so to be offered) would purchase at such current Fair Market Value
and the denominator of which shall be the number of shares of Common Stock
outstanding on such record date plus the number of additional shares of Common
Stock to be offered for subscription or purchase (or into which



                                       34
<PAGE>

the convertible securities so to be offered are initially convertible). In case
such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent.
Shares of Common Stock owned by or held for the account of the Company shall not
be deemed outstanding for the purpose of any such computation. Such adjustment
shall be made successively whenever such a record date is fixed and in the event
that such rights, options or warrants are not so issued, the Exercise Price
shall be adjusted to be the Exercise Price which would then be in effect if such
record date had not been fixed.

                  (d) In case the Company shall fix a record date for the making
of a distribution to all holders of the Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of
indebtedness, cash (other than a regular quarterly cash dividend not in excess
of 150% of the previous regular quarterly cash dividend out of the earnings or
retained earnings of the Company), assets (other than a dividend payable in
shares of Common Stock) or subscription rights or warrants (excluding those
referred to in Section 11(c) hereof), the Exercise Price to be in effect after
such record date shall be determined by multiplying the Exercise Price in effect
immediately prior to such record date by a fraction, the numerator of which



                                       35
<PAGE>

shall be the Fair Market Value of the shares of Common Stock on such record
date, less the fair market value (as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent) of the portion of the assets or evidences of
indebtedness so to be distributed or of such subscription rights or warrants
applicable to one share of Common Stock and the denominator of which shall be
such current Fair Market Value of the shares of Common Stock. Such adjustment
shall be made successively whenever such a record date is fixed and in the event
that such distribution is not so made, the Exercise Price shall again be
adjusted to be the Exercise Price which would then be in effect if such record
date had not been fixed.

                  (e) Unless the Company shall have exercised its election as
provided in Section 11(f), upon each adjustment of the Exercise Price as a
result of the calculations made in Section (c) and (d), each Right outstanding
immediately prior to the making of such adjustment shall thereafter evidence the
right to purchase, at the adjusted Exercise Price, that number of one
one-hundredths of a share of Preferred Stock obtained by (i) multiplying (x) the
number of one one-hundredths of a share of Preferred Stock covered by a Right
immediately prior to the adjustment pursuant to this Section 11(e) by (y) the
Exercise Price in effect immediately prior to such adjustment of the Exercise
Price and (ii) dividing the product so obtained by the Exercise Price in effect
immediately after such adjustment of the Exercise Price.



                                       36
<PAGE>

                  (f) The Company may elect on or after the date of any
adjustment of the Exercise Price pursuant to Section (c) and (d) to adjust the
number of Rights in substitution for any adjustment pursuant to Section 11(e) in
the number of one one-hundredths of a share of Preferred Stock purchasable upon
the exercise of a Right. Each of the Rights outstanding after such adjustment of
the number of Rights shall be exercisable for the number of one one-hundredths
of a share of Preferred Stock for which a Right was exercisable immediately
prior to such adjustment. Each Right held of record prior to such adjustment of
the number of Rights shall become that number of Rights obtained by dividing the
Exercise Price in effect immediately prior to adjustment of the Exercise Price
by the Exercise Price in effect immediately after adjustment of the Exercise
Price. The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made. This record date may
be the date on which the Exercise Price is adjusted or any day thereafter, but,
if the Right Certificates have been issued, shall be at least 10 days later than
the date of the public announcement. If the Right Certificates have been issued,
upon each adjustment of the number of Rights pursuant to this Section 11(e), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Right Certificates on such record date Right Certificates evidencing,
subject to Section 14 hereof, the additional Rights, if any, to which such
holders shall be entitled as



                                       37
<PAGE>

a result of such adjustment, or, at the option of the Company, shall cause to be
distributed to such holders of record in substitution and replacement for the
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Right Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein and shall be registered in
the names of the holders of record of Right Certificates on the record date
specified in the public announcement.

                  (g) 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.

                  (h) 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 Right Certificates theretofore and thereafter issued may
continue to express the Exercise Price and the number of shares to be issued
upon exercise of the Rights as in the initial Right Certificates issued
hereunder but, nevertheless, shall represent the Rights as so adjusted.

                  (i) 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



                                       38
<PAGE>

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.

                  (j) 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 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.

                  Section 12. Certification of Adjusted Exercise Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11, 13, 23 or
27, 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



                                       39
<PAGE>

summary thereof to each holder of a Right 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 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



                                       40

<PAGE>

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, in one or more 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 at a price equal to the then current Exercise Price
multiplied by the number of one one-hundredths of a share of Preferred Stock for
which a Right is then exercisable, in accordance with the terms of this
Agreement and in lieu of shares of Preferred Stock, such number of shares of
validly issued, fully paid, non-assessable and freely tradeable 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 (1) multiplying the then current Exercise Price by the number of one
one-hundredths of a share of Preferred Stock for which a Right is then
exercisable and dividing that product by (2) 50% of the then per share Fair
Market Value of the Common Stock of the Principal Party on the date of the
consummation, 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 Agreement; (iii) the term "Company" for all purposes of



                                       41
<PAGE>

this 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 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



                                       42
<PAGE>

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
survives such merger or 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



                                       43
<PAGE>

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 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 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



                                       44
<PAGE>


and that such transaction shall not result in a default by the Principal Party
under this 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 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



                                       45
<PAGE>
                  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 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



                                       46
<PAGE>

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 Right 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 Right 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 that are integral multiples of
one one-hundredth of a share) upon exercise of the Rights or to distribute
certificates which evidence fractional shares (other than fractions that are
integral multiples of one 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



                                       47
<PAGE>
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 shares that are not integral multiples of one
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 Right Certificates at the time such Right Certificates 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 Agreement, except the rights of action given to the Rights Agent in
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the holders of record of the
Common Stock); and any holder of record of any Right 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 Right 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



                                       48
<PAGE>

Company to enforce, or otherwise act in respect of, his right to exercise the
Rights evidenced by such Right Certificate in the manner provided in such Right
Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and will be entitled to specific performance of the
obligations under, and injunctive relief against actual or threatened violations
of, the obligations of any Person subject to this Agreement.

                  Section 16. Agreement of Right Holders. 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 certificates for Common Stock registered in the name
         of the holders of Common Stock (together, as applicable, with the
         Summary of Rights), which certificates for Common Stock shall also
         constitute certificates for Rights, and not by separate Right
         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 Right Certificates are
         transferable only on the registry books of the Rights Agent if
         surrendered at the office of the Rights Agent



                                       49
<PAGE>

         designated for such purpose, duly endorsed or accompanied by
         a proper instrument of transfer; and

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

                  Section 17. Right Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of 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 Right
Certificate be construed to confer upon the holder of any Right Certificate, as
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof (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



                                       50
<PAGE>

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

                  Section 18.  Concerning the Rights Agent.

                  (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
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 Agreement, including the cost and expenses of defending
against any claim of liability relating to the Rights or this 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 Agreement in reliance upon
any Right 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



                                       51
<PAGE>

and to be signed, executed and, where necessary, verified or acknowledged, by
the proper person or persons.

                  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 Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto, provided that such corporation would
be eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement any of the 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
Right Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall

                                       52
<PAGE>

have the full force provided in the Right Certificates and in this
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 Right Certificates so countersigned; in case at
that time any of the Right Certificates shall not have been countersigned, the
Rights Agent may countersign such Right Certificates either in its prior name or
in its changed name; in all such cases such Right Certificates shall have the
full force provided in the Right Certificates and in this Agreement.

                  Section 20. Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Company and the holders of
Right Certificates by their acceptance thereof shall be bound:

                  (a) The Rights Agent may consult with legal counsel (who may
be legal counsel for the Company), and the opinion of such counsel shall be full
and complete authorization and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking or suffering any
action hereunder, such



                                       53
<PAGE>

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 Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable hereunder only for its
own negligence, bad faith or willful misconduct. Anything to the contrary
notwithstanding, in no event shall the Rights Agent be liable for special,
indirect, consequential or incidental loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Rights Agent has been
advised of the likelihood of such loss or damage.

                  (d) The Rights Agent shall not be liable for or by reason of
any of the statements of fact or recitals contained in this Agreement or in the
Right Certificates (except its counter-signature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

                  (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any



                                       54

<PAGE>

Right Certificate (except its countersignature thereof); nor shall it be
responsible for any breach by the Company of any covenant or condition contained
in this Agreement or in any Right Certificate; nor shall it be responsible for
any 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 Right 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 Agreement or any Right 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 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 apply to such officers for advice or
instructions in



                                       55
<PAGE>

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 Agreement. Nothing herein shall preclude the Rights Agent from
acting in any other capacity for the Company or for any other legal entity.

                  (i) The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys or agents, and the Rights Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company resulting from any such
act, default, neglect or misconduct, provided reasonable care was exercised in
the selection and continued employment thereof.

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Stock and the Preferred Stock by registered or
certified mail. The Company may remove the Rights Agent or any successor Rights



                                       56
<PAGE>

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, 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
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Company), then the incumbent Rights Agent or the holder of
record of any Right Certificate may apply to any court of competent jurisdiction
for the appointment of a new Rights Agent. Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be (a) 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


                                       57
<PAGE>

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 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 Right Certificates. Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be. 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 Right Certificates.  
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved



                                       58
<PAGE>

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 Right Certificates made in
accordance with the provisions of this 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 or (ii) the Final
Expiration Date, at a redemption price of $.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.

                  (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



                                       59
<PAGE>

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 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 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, 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



                                       60
<PAGE>

Section 11(a)(i) or to pay any dividend to the holders of record of its shares
of Common Stock payable in shares of capital stock of any class or to make any
other distribution to the holders of record of its Common Stock (other than a
regular periodic cash dividend at a rate not in excess of 150% of the rate of
the last cash dividend theretofore paid), 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 Right 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



                                       61
<PAGE>

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 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 the event referred to in Section 11(a)(ii) shall
occur, then the Company shall as soon as practicable thereafter, in accordance
with Section 25 hereof, give to each holder of a Right notice of the occurrence
of such event, which notice shall describe the event and the consequences of the
event to holders of Rights under Section 11(a)(ii) hereof.

                  Section 25.  Notices.  Notices or demands authorized by
this Agreement to be given or made by the Rights Agent or by the holder of
record of any Right Certificate or Right to or on the Company shall be

                  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

<PAGE>

Rights Agent shall if the Company so directs, supplement or amend this Agreement

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 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 Right 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. This Agreement may be amended or
supplemented at any time with the approval of a majority of the registered
holders of the Right Certificates (and, prior to the Distribution Date, the
Common Stock). Notwithstanding anything contained in this Agreement to the
contrary, no supplement or amendment shall be made which changes the Redemption
Price or the Final Expiration Date.

                  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 null and 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



                                       64
<PAGE>

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.

                  (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



                                       65
<PAGE>

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 null and
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 take all such action as may be necessary to authorize additional
shares of Common Stock 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 fractional shares, the Company shall pay to the
registered holders of the Right 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 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 Agreement. Nothing in this
Agreement shall be construed to give to any person or corporation other than the
Company, the Rights Agent and the registered holders of the Right 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 Agreement; but this Agreement shall be for the sole and exclusive
benefit of the Company, the Rights Agent and the holders of record of the Right
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 Agreement and each Right
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.

                  Section 31. Counterparts. This 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 Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

restriction of this 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 Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

                     EXERCISED OR TRANSFERRED TO ANY PERSON.

                                  NAC RE CORP.

                          SUMMARY OF RIGHTS TO PURCHASE
                         SERIES A JUNIOR PREFERRED STOCK


                  On June 10, 1998, the Board of Directors of NAC Re Corp. (the
"Company") declared a dividend distribution of one Preferred Stock Purchase
Right for each outstanding share of Common Stock, par value $.10 per share (the
"Common Stock"), of the Company. The distribution is payable as of June 22, 1998
to stockholders of record on that 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 A Junior Preferred Stock
(the "Preferred Stock") at a price of $150.00 per one one-hundredth (1/100) of a
share ("Exercise Price"). The description and terms of the Rights are set forth
in a Rights Agreement (the "Rights Agreement") 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 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") 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

<PAGE>


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 would not be exercisable,
would not be represented by a separate certificate, and would not be
transferable apart from the Company's Common Stock, but will instead be
evidenced, with respect to any of the Common Stock certificates outstanding as
of June 22, 1998, by such Common Stock certificate with a copy of this Summary
of Rights attached thereto. 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 voting stock
for or pursuant to the terms of any such plan, (D) any person or group of
affiliated or associated persons 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
issued and 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% 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)) or (E) any person who, as
of June 22, 1998, together with all affiliates and associates of such person,
was the Beneficial Owner of 15% or more of the voting stock of the Company
outstanding as of such date; provided, however, that any person described in
this clause (E) shall no longer be an exempt person and shall become an
Acquiring Person if (i) such person, together with all affiliates and associates
of such person, after June 22, 1998, acquires beneficial ownership of an
additional 1% or more of the voting stock (unless such acquisition is pursuant
to a transaction described in clause (D)(i) or (D)(ii) above) or (ii) such
person, together with all affiliates and associates of such person, after June
22, 1998, reduces its beneficial ownership of the voting stock to less than 15%
of the outstanding voting stock and thereafter acquires beneficial ownership of
15% or more of the outstanding voting stock (unless such acquisition is pursuant
to a transaction described in clause (D)(i) or (D)(ii) above).

                  Until the Distribution Date (or earlier redemption, exchange
or expiration of the Rights), new Common Stock certificates issued after June
22, 1998 will contain a legend incorporating the Rights Agreement by reference.
Until the Distribution Date (or earlier redemption, exchange or expiration of
the Rights), the surrender for transfer of any of the Common Stock certificates
outstanding as of June 22, 1998, 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 certificate. As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right 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 certificates alone will evidence the Rights from and after the
Distribution Date.

                  The Rights are not exercisable until the Distribution Date.
The Rights will expire at the close of business on June 10, 2008, unless earlier
redeemed by the Company as described below.

                  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 the greater of $0.10 per share or 100
times the cash dividends declared on the Company's Common Stock. In addition,
the holders of the Preferred Stock are entitled to receive 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 $0.10
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.

                  The number of shares of Preferred Stock issuable upon exercise
of the Rights and Exercise Price of the Rights are subject to certain
adjustments from time to time in the



                                        3
<PAGE>

event of a stock dividend on, or a subdivision or combination of, the Common
Stock. The Exercise Price for the Rights also 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 or exchanged, 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 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 having a market
value at the time of such transaction equal to two times the Exercise Price.

                  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 provisions 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 shares of the Preferred Stock having a market
value at the time of the transaction equal to two times the Exercise Price (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.

<PAGE>
                  At any time on or prior to the close of business on the
earlier of (i) the tenth day after the time that a person has become an
Acquiring Person, or (ii) June 10, 2008, the Company may redeem the Rights in
whole, but not in part, at a price of $.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.

                  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 a Current Report on Form 8-K
dated June 10, 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.

                  As provided in the Rights Agreement, the Exercise Price and

                         SERIES A JUNIOR PREFERRED STOCK
                                       OF
                                  NAC RE CORP.

                     Pursuant to Section 151 of the Delaware
                             General Corporation Law


                  I, Celia R. Brown, Secretary of NAC Re 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 pursuant to the authority conferred upon the Board of
Directors by the Restated Certificate of Incorporation of the Company, the Board
of Directors on June 10, 1998 adopted the following resolution which creates a
series of shares of Preferred Stock designated as Series A Junior Preferred
Stock, as follows:

                  RESOLVED, that pursuant to Section 151(g) of the Delaware
General Corporation Law and the authority vested in the Board of Directors of
the Company in accordance with the provisions of ARTICLE FOURTH of the Restated
Certificate of Incorporation of the Company, a series of Preferred Stock of the
Company be, and hereby is, created, and the powers, designations, preferences
and relative, participating, optional or other special rights of the shares of
such series,

<PAGE>


and the qualifications, limitations or restrictions thereof,
be, and hereby are, as follows:

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series A Junior Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting such series shall be
277,500.

                  Section 2.  Dividends and Distributions.
                  (A)  Subject to the provisions for adjustment
hereinafter set forth, and subject to the rights of the holders of any shares of
any series of Preferred Stock ranking prior and superior to the Series A
Preferred Stock with respect to dividends, the holders of shares of Series A
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, $0.10 par value per share, of the Company (the "Common Stock")
and (ii) a preferential cash dividend (the "Preferential Dividends"), if any, in
preference to the holders of Common Stock, on the first day of March, June,
September and December 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 A Preferred Stock, payable in an
amount (except in the case of



                                        2
<PAGE>





the first Quarterly Dividend Payment if the date of the first issuance of Series
A 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
$0.10 per share of Series A Preferred Stock less the per share amount of all
cash dividends declared on the Series A 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 A Preferred Stock. In the
event the Company shall, at any time after the issuance of any share or fraction
of a share of Series A 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



                                        3
<PAGE>





on each then outstanding share of Series A 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 A 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 "Dividends" and the multiple of such cash and non-cash dividends
on the Common Stock applicable to the determination of the 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 June 22, 1998 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, then in each such case the Dividend Multiple thereafter
applicable to the determination of the amount of Dividends which holders of
shares of Series A 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



                                        4
<PAGE>


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 Dividend at the same time
it declares any cash or non-cash dividend or distribution on the Common Stock in
respect of which a Dividend is required to be paid. No cash or non-cash dividend
or distribution on the Common Stock in respect of which a Dividend is required
to be paid shall be paid or set aside for payment on the Common Stock unless a
Dividend in respect of such dividend or distribution on the Common Stock shall
be simultaneously paid, or set aside for payment, on the Series A Preferred
Stock.
                  (C) Preferential Dividends shall begin to accrue on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issuance of any shares of Series A
Preferred Stock. Accrued but unpaid Preferential Dividends shall cumulate but
shall not bear interest. Preferential Dividends paid on the shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding.

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



                                        5
<PAGE>

                  (A) Subject to the provisions for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 100 votes on all matters submitted to a vote of the holders of the Common
Stock. The number of votes which a holder of Series A 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 June 22, 1998 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, 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 A 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 Restated
Certificate of Incorporation or by law, the holders of shares of Series A
Preferred Stock and the holders of shares of Common Stock shall vote together as
one class on



                                        6
<PAGE>

all matters submitted to a vote of stockholders of the Company.

                  (C) In the event that the Preferential Dividends accrued on
the Series A 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 Preferred Stock of the Company
of all series (including the Series A Preferred Stock), other than any series in
respect of which such right is expressly withheld by the Restated Certificate of
Incorporation or the authorizing resolutions included in any 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 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 incapaci- ty
or until such earlier time as all accrued and unpaid Preferential Dividends upon
the outstanding shares of Series A Preferred Stock shall have been paid (or
irrevocably set aside for payment) in full. The holders of shares of Series A
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 A Preferred Stock shall have



                                        7
<PAGE>

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

                  Section 4.  Certain Restrictions.

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



                                        8
<PAGE>


                         (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
         A 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 A Preferred Stock, unless dividends are paid
         ratably on the Series A Preferred Stock and all such parity stock on
         which dividends are payable or in arrears in proportion to the total
         amounts to which the holders of all such shares are then entitled 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
         Series A 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 A Preferred Stock; or



                                        9
<PAGE>


                        (iv) purchase or otherwise acquire for consideration any
         shares of Series A Preferred Stock, or any shares of stock ranking on a
         parity with the Series A 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 of such corporation or other entity 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 A
Preferred Stock except upon exercise of Rights issued pursuant to that certain
Rights Agreement dated as of June 18, 1998 between the Company and American
Stock Transfer & Trust Co., as Rights Agent, as it may be amended from time to
time, a copy of which is 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 A Preferred Stock.

                  Section 5. Reacquired Shares. Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Company in any manner whatsoever
shall be retired and cancelled 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



                                       11
<PAGE>


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 A
Preferred Stock unless the holders of shares of Series A Preferred Stock shall
have received for each share of Series A Preferred Stock, subject to adjustment
as hereinafter provided, (A) $1,500.00 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 A Preferred Stock, unless
simultaneously therewith distributions are made ratably on the Series A
Preferred Stock and all other shares of such parity stock in proportion to the
total amounts to which the holders of shares of Series A 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 A 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



                                       12
<PAGE>


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 the event the Company
shall at any time after June 22, 1998 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, then, in each
such case, the Liquidation Multiple thereafter applicable to the determination
of the Participating Liquidation Amount to which holders of Series A 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 June 22, 1998 in respect of their shares of Common Stock
any share of capital stock



                                       13

<PAGE>

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 A Preferred Stock shall be
adjusted so that after such event the holders of Series A Preferred Stock shall
be entitled, in respect of each share of Series A 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



                                       14
<PAGE>


to receive 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 June 22, 1998 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
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 A 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



                                       15
<PAGE>

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 June 22, 1998 in respect of their shares of Common Stock
any right or 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 A Preferred Stock shall each be adjusted so that after such
event each holder of a share of Series A Preferred Stock shall be entitled, in
respect of each share of Series A Preferred Stock held, in addition to such
rights in respect thereof to which such holder was entitled immediately prior to

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 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 distributions 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



                                       17

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 reclassifica- tion 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



                                       18

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 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 on 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



                                       19
<PAGE>


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 A Preferred Stock shall at the same time be
similarly exchanged for or changed into the aggregate amount of stock,
securities, cash and/or other 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 A Preferred Stock
required by the provisions hereof shall be effective as of the time at which the
event requiring such adjustments occurs.

<PAGE>


                  (B) The Company shall give prompt written notice to each
holder of a share of Series A 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 A 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 A Preferred Stock in any other manner permitted by law,
the provisions hereof and the Amended and Restated Certificate of Incorporation
of the Company.

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



                                       21
<PAGE>


shall not be amended in any manner which would adversely affect the rights,
privileges or powers of the Series A 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 A Preferred Stock,
voting together as a single class.

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

                               [NAC RE LETTERHEAD]


                                                              June 23, 1998




To Our Stockholders:

                  On June 10, 1998, your Board of Directors adopted a
Stockholder Rights Plan, which replaced the Company's rights plan that expired
on June 21, 1998. As part of the new Plan, NAC Re declared a dividend
distribution of one Preferred Stock Purchase Right (a "Right") on each
outstanding share of Common Stock of the Company. A Summary of Rights explaining
the terms of the Rights is enclosed herewith.

                  We believe a Stockholders' Rights Plan enhances your Board's
ability to represent the interests of stockholders of the Company effectively in
the event of an unsolicited takeover attempt. The Board considers the Plan to be
an appropriate means of protecting both your right to retain your equity
investment in the Company and the full value of that investment. Many other
companies have adopted stockholders' rights plans similar to the Plan approved
by the Board.

                  There are numerous means by which an acquiror can obtain
control of a target company upon terms which are unfair to its stockholders and
by means which significantly weaken the target company. The Rights issued under
the Plan contain provisions designed to protect stockholders against abusive
practices which can unfairly pressure stockholders to sell their stock at less
than full value. Over 2,000 other U.S. companies have issued rights similar to
those approved by your Board to protect their stockholders against these
tactics.

                  The distribution of these Rights is not intended to prevent a
takeover of the Company on terms beneficial to its stockholders and, in fact,
will not do so. However, it should deter an attempt to acquire the Company in a
manner or on terms that the Board determines not to be in the best interests of
its stockholders. The Rights are designed to deal with the very serious problem
of a takeover attempt that deprives the Company's Board and its stockholders of
any real opportunity to determine the destiny of the Company.


<PAGE>

                  The Rights may be redeemed by the Company at $.01 per Right
prior to the close of business on the tenth day after a public announcement that
beneficial ownership of 15% or more of the Company's voting stock has been
accumulated by a single acquiror or group. Thus, the Rights should not interfere
with a negotiated merger or other business combination approved by the Board.

                  Issuance of the Rights does not in any way weaken the
financial strength of the Company or interfere with its business plans. The
issuance of the Rights has no present dilutive effect, will not affect reported
earnings per share, is not taxable to the Company or to you under current
federal income tax law, and will not change the way in which the Company's
shares of Common Stock may be traded. If the Rights should become exercisable,
stockholders, depending on then existing circumstances, may recognize taxable
income.

                  The Board was aware when it acted that some people have
advanced arguments that securities of the sort we are issuing deter legitimate
acquisition proposals. The Board carefully considered those views and concluded
that the arguments are speculative and unconvincing and certainly do not justify
leaving stockholders with less effective protection against unfair treatment by
an acquiror who, after all, would be seeking its own advantage, not yours. The
Board believes that these Rights represent a sound, reasonable and appropriate
means of addressing the complex issues of corporate policy developed as a
response to the threat of coercive takeovers.

                  In declaring the Rights dividend, we have expressed our
confidence in NAC Re's future and we believe we have increased your ability to
participate in that future.

                                                     Sincerely,

                                                     /s/ Ronald L. Bornhuetter
                                                     ---------------------------
